Description

{House opening/closing method by winding multiple types of integrated covering sheets and the system}

The present invention relates to a method for opening and closing a greenhouse by winding various types of connected integral covering sheets to control the microclimate by heat preservation, rain protection, and shading in a crop cultivation and work or rest house that opens and closes the covering material according to changes in the weather environment, and to a system therefor.

Animals and plants have evolved into forms suitable for growth in changing weather environments or have survived by moving to suitable environments. However, weather conditions such as temperature, sunlight, rain, and wind do not always provide suitable environmental conditions for people, livestock, and crops due to changes in weather environments.

Accordingly, as a means of dealing with this, facilities are being utilized that either permanently cover the area with covering materials for insulation, rain protection, shading, wind protection, insect repellent, etc., or in some cases, facilities that can be opened and closed.

In particular, it is widely used to improve the quality and productivity of horticultural crops by controlling the environment through insulation and rain cover in vinyl greenhouses for crop cultivation and blocking rain.

Its advantages include low-temperature insulation, suppression of heat source emission during heating, suppression of disease occurrence due to rain cover, planned nutrient management, and prevention of nutrient leaching. In addition, physical damage to crops due to rain can be avoided, and stable crop cultivation can be achieved more stably by blocking frost and wind.

A disadvantage in terms of crop cultivation is that when there is little light, there is shading from the covering material or structure, which can have a negative effect on crop growth.

However, certain fixed covering facilities do not respond flexibly to environmental changes. For example, vinyl covering is suitable for heat preservation and rain protection, but when the temperature is high and the light is strong in the summer, the temperature inside the facility rises significantly. Therefore, ventilation or shading is attempted to improve this, but in some cases, there are limits to the control.

On the other hand, when the light is strong, appropriate shading is required.

In particular, during high temperatures, it is necessary to open the facility to lower the temperature of the facility and provide appropriate shading to suppress the amount of light entering. For insulation, rain protection, or shading, a part of the house is covered with fixed coverings, and for the remaining part, the coverings are opened and closed using a motorized winding method (Korean Utility Model Registration No. 20-0168700, November 13, 1999) to control the microclimate environment inside the facility.

In the conventional opening/closing method using a winding motor in which one side is fixed to a vinyl fixing pad and the other side of the vinyl corresponding to the lower part in the direction of gravity is fixed to a winding pipe and opened/closed, if the vinyl attached to the winding pipe becomes loose or stretched, causing the winding pipe to bend or stretch, there are cases in which the winding pipe cannot be wound horizontally.

On the other hand, the conventional dome-shaped single-action house that opens and closes only part of the left and right sides is fixed with vinyl pads at the left and right side elevations, and the side vinyl and the winding pipe are hung on the house. To minimize damage or shaking due to the wind, the vinyl is fixed with vinyl fixing pads and the entire house is held at regular intervals with binder strings, but it is not fixed stably enough.

Also, since light transmittance may decrease by 15-20% due to contamination of the covering material when there is insufficient light, it is recommended to open the covering material or completely open the house for ventilation during high temperatures. At this time, in the case of a dome-shaped house, a vinyl fixing pad is installed on the ridge to open and close the winding, that is, the vinyl fixing pad is moved from the measurement position to the ridge, and even if it is tied with a binder string or at a regular interval, the downward pulling of the covering material is a phenomenon that occurs only by the load of the pipe, so the higher the winding pipe is located in the house, the lower the potential energy due to gravity, so the tension of the covering material becomes weak, and the covering material may sway in the wind or the vinyl may sag due to rainwater collecting in the rain. However, if the binder string is tightened to alleviate this, the winding pipe will rotate, which will put a load on it, and this may cause damage to the covering material such as the vinyl.

To improve this, a method was developed to divide the house roof into sections to reduce the opening and closing range by a single winding pipe, install a winding pipe catch, and fix the covering vinyl by rotating it in reverse at the catch section (Korean Patent Publication No. 10-2016-0082314, July 8, 2016).

Meanwhile, in order to prevent temperature rise inside the facility during high temperature periods, even if the covering vinyl is completely opened, a separate shading net is installed to block out light when the sunlight is too strong. However, although installing it on a separate shading net stand has a good effect on suppressing temperature rise, it requires a lot of investment costs, and covering it with a shading net over vinyl does not have a relatively large effect on lowering the temperature due to shading.

Meanwhile, a movable shading net is installed separately inside the house. In this case, a shading net with a fixed shading rate is generally used. Therefore, it is not flexible in terms of application to various light environments. In addition, if the house is low in height, the space is narrow, making it inconvenient to work with agricultural machinery, so there may be limitations in application depending on the structure and shape of the house. In this regard, Korean Patent Publication No. 10-2012-0074399 (July 6, 2012) discloses a method of adjusting the shading rate by a shading method using a moving shading material to overcome the limitations of the fixed shading rate of the shading net.

Meanwhile, Fig. 14 is a photo of a greenhouse for crop cultivation destroyed by heavy snow. Even if a greenhouse is installed relatively sturdily, it can collapse due to heavy snow, and as shown in Fig. 15, damage caused by wind during a typhoon can occur, resulting in economic loss.

Recently, as ICT technology has been applied to the environmental control system of crop cultivation facilities, various methods have been suggested, such as a method of remotely controlling the covering status of a shade net while observing it in real time (Korean Patent Publication No. 10-2018-0110485, October 10, 2018). However, there are many areas that need to be improved in a situation where the conventional, stereotyped methods are still in place.

As described above, facilities that are fixedly covered with covering materials for insulation, rain protection, shading, wind protection, insect protection, etc., or that can be opened and closed as needed, should be able to easily control the opening and closing of the covering material, ensure a stable covering state, and be completely openable to easily adapt to changes in the weather environment and protect the covering material and facilities from weather disasters in order to solve the above problems.

Accordingly, the present invention discloses a house opening/closing method and system by winding various types of connected integral covering sheets.

Republic of Korea Registered Utility Model No. 20-1999-0168700 (November 13, 1999) Republic of Korea Publication Patent No. 10-2011-0092133 (August 17, 2011) Republic of Korea Publication Patent No. 10-2012-0074399 (July 6, 2012) Republic of Korea Publication Patent No. 10-2016-0082314 (July 8, 2016) Republic of Korea Publication Patent No. 10-2018-0110485 (October 10, 2018)

The present invention aims to solve the problems of the prior art by providing a method for opening and closing a house by winding various types of connected integral covering sheets in a manner that stably covers and opens and closes the covering without a binder string or vinyl fixing pad that holds the covering material, and a system therefor.

In addition, the present invention provides a winding pipe fixing circular wheel that is installed horizontally at a certain interval in the length direction of the house on the rafters or crossbars near the ground at the lower left and right sides of the house to prevent bending of the winding pipe due to the tension of the covering material; and

A cladding material winding pipe fixing circular wheel having a plurality of bearings provided around the inner wall of the above-mentioned cladding material winding pipe fixing circular wheel to ensure smooth friction between the cladding material and the circular wheel and smooth flow of the cladding material; and

The purpose of this invention is to provide a method for opening and closing a house by winding various types of connected integral covering sheets, and a system thereof, characterized by including a winding pipe fixed circular wheel having an open upper portion so that covering material can be introduced into the circular wheel.

The purpose of this invention is to provide a house opening/closing method and system by winding of various types of connected integral covering sheets, characterized in that it includes a covering material winding pipe that rotates in place without moving significantly within a fixed circular wheel of the winding pipe.

In addition, the present invention aims to provide a method for opening and closing a house by winding a plurality of connected integral covering sheets and a system thereof, characterized in that the house covering shape is controlled by using an integral covering material in which two to five or more types of sheets, such as vinyl, shading nets, nets, and insect screens, are connected.

In addition, the purpose is to provide a method for opening and closing a house by winding various types of connected integral covering sheets, and a system thereof, characterized by having fixed winding pipes located at the lower left and right sides of the house and 1 to 2 movable winding pipes and a driving motor installed separately at two covering material connecting sections and moving left and right.

In order to achieve this purpose, a vinyl house opening/closing method according to one embodiment of the present invention may have 1 to 2 winding pipes that can move to the left and right of the house rafters and fixed winding pipes at the bottom of the left and right sides of the house, respectively.

When the vinyl of the house is removed to completely open it, the winding pipe goes up while wrapping the covering material from the side of the house to the crossbar of the ridge, so it works normally. However, when going down to the opposite side over the ridge, the pipe's potential energy works in the direction of gravity, but there is no force holding it from above, so the winding pipe slides down, making normal winding impossible. In addition, since the winding pipe cannot return to its original position without a fixed guide wire or sheet that suspends the winding pipe, complete opening was impossible in this way.

Although it is not a common method, one way to completely open the house is to place a vinyl fixing pad on the ridge and roll up the vinyl covering material using a winding pipe on the left and right sides, or to divide the open area into several sections and open and close it by winding it up.

In the present invention, since a movable winding pipe is installed at a seat-to-seat connection and a fixed winding pipe is installed at each end of a connected integral covering material to drive a winding motor, the fixed winding pipe always holds the covering material while rotating forward and backward to wind the covering material, and at the same time, since two movable winding pipes move while rotating forward and backward to wind the covering material, various forms of covering can be achieved, such as covering a house in an almost completely open form using various covering materials. In addition, in this operating method, a separate binder string or vinyl fixing pad that was used to hold the covering material in a conventional house is not necessary.

More specifically, as an embodiment of the present invention, a multi-sheet connection integral covering is formed by connecting two types of sheets at both ends of a vinyl covering, placing two movable winding pipes at the connection portion, and connecting another type of sheet to the end of the sheet connected to the vinyl, thereby forming a five-type sheet connection integral covering. At this time, the sheets connected to the vinyl can connect five types of sheets including vinyl, such as two types of covering materials having different shading rates and a net with a large mesh that can be considered an open covering form. In this way, by winding the covering material by the forward and reverse rotation of the two movable winding pipes on the left and right sides of the vinyl and the winding of the left and right fixed winding pipes, various forms of covering such as full vinyl covering, full shading, partial vinyl covering, partial shading, and complete openness can be formed depending on the weather conditions.

At this time, in order to implement various house covering forms, unlike the conventional winding method, the movable winding pipe is wound by overlapping two types of covering materials adjacent to the winding pipe during forward and reverse rotation, and the fixed winding pipe installed at the bottom left and right of the house may be wound with single layers of covering materials in succession.

In addition, in the conventional method of fixing the covering material, it was necessary to hold it with a vinyl fixing pad and a binder string in order to fix the covering material tightly to the house. However, in the present invention, since the fixed winding pipes at the bottom left and right of the house can always maintain the tension of the covering material and stably cover it, a separate binder string or vinyl fixing pad is not necessary.

More specifically, since the present invention does not have a vinyl fixing pad and a binder string, it must be a form in which the covering material is always held and wound. If the winding pipe is hung by tying a binder string, stable adhesion of the covering material such as vinyl is not achieved. Therefore, in order to solve this problem, a plurality of bearings are provided on the inner wall of the winding pipe circular wheel so that the fixed winding pipe has less friction when winding the covering material and minimizes the movement of the winding pipe, and a winding pipe fixed circular wheel having an opening that is open in the upper direction to allow the covering material to flow is installed at regular intervals. By having the winding pipes that operate at the bottoms of both sides of the house operate in the center of the circular wheel, the covering material can be held well without bending of the winding pipe.

As described above, the present invention is characterized by opening and closing a house by winding a variety of sheet-connected integral covering sheets.

According to the method for opening and closing a house by winding various types of connected integral covering sheets of the present invention and the effect of the system thereof, complete opening is possible, so facility collapse damage caused by heavy snow in winter can be prevented.

In addition, according to the effect of the method for opening and closing a house by winding the various types of connected integral covering sheets of the present invention and the system thereof, crop productivity can be increased by suppressing temperature rise through appropriate shading and opening.

In addition, according to the effect of the house opening/closing method and system thereof by winding the various types of connected integral covering sheets of the present invention, on cloudy days with insufficient light, the vinyl can be opened to alleviate the decrease in growth due to insufficient light.

In addition, according to the effect of the house opening/closing method and system by winding the various types of connected integral covering sheets of the present invention, damage to vinyl and facility caused by strong winds can be prevented in advance.

In addition, according to the method for opening and closing a house by winding various types of connected integral covering sheets of the present invention and the effect of the system, the problem of salt accumulation can be solved by fully opening the house when it rains.

In addition, according to the effect of the house opening/closing method and system thereof by winding the various types of connected integral covering sheets of the present invention, the impact of snow, strong winds, etc. can be reduced by opening the covering material, so that the weight of the frame can be reduced, and thus the installation cost can be reduced.

In addition, according to the effect of the house opening/closing method and system by winding the various types of connected integral covering sheets of the present invention, abnormal operation due to bending of the winding pipe, etc. can be minimized, so that the opening/closing of the covering material is stable.

Hereinafter, the present invention will be described more specifically based on examples.

The following examples are provided to facilitate understanding of the present invention, but the present invention is not limited to the following examples.

A simple method of covering a house with various types of sheets in various ways is to install the house frames in the same location with the number of sheets at a certain interval and height, and then open and close each covering material by controlling its own winding motor. However, this can require a lot of installation costs.

The method for opening and closing a house by winding various types of connected integral covering sheets of the present invention and the system thereof can be said to be a method that enables partial opening of a skylight, full opening, heat preservation, rain protection, and various types of shading efficiently with minimal facilities.

In conventional houses, for temperature control, the opening and closing of the house was mainly done by opening and closing the side windows, partially opening and closing the skylights, and operating the ventilation fan. Here, shading was difficult to effectively respond to changes in the daily light environment, temperature environment, etc. by opening and closing the shading net with a fixed shading rate while the vinyl was covered, or by applying shading material to the vinyl. In particular, it was impossible to avoid the risk of economic loss, such as damage to crop cultivation facilities installed at high cost due to snow, wind, etc.

In addition, as shown in Fig. 1, a conventional general house is fixed and assembled with dome-shaped rafters (2) and crossbars (6) by steel apertures, and vinyl covering is fixed and supported on the side of the house by vinyl fixing pads (3) and is supported by binder strings (5), and the side window part is moved up and down by the winding of a movable winding pipe (4) to adjust the area of the side window opening, thereby controlling the temperature by ventilation, and when the temperature rises further in the summer, the brightness and temperature are controlled by covering with a shading net or opening and closing the shading net.

In the present invention, in addition to vinyl, one or two types of covering materials, or at most four types, are connected to form a covering sheet, and by appropriately placing a winding pipe in the middle, various types of coverings are possible. Of course, covering can be simply done by connecting two or three covering materials, and it is technically possible to add and use more covering materials, but considering the growth characteristics of crops and the structural characteristics such as the facility surface area, it is reasonable to operate by connecting up to five types of covering materials including vinyl.

The covering method using a multi-sheet connection integral covering material can have fixed winding pipes on both sides and 1 to 2 movable winding pipes in the middle of the connecting section of the integral sheet. When 1 movable winding pipe is placed, the entire surface or part can be covered by adjusting 3 types of connecting sheets including vinyl, and when 2 movable winding pipes are placed, at least 3 types or at most 5 types of covering materials can be connected at the same time, so that the entire surface or part can be covered in a wider variety of covering forms. In addition, more winding movable pipes can be placed, or covering materials with different shading rates or other functions can be used.

In the present invention, more specifically, when the length of the house is long and the length of the covering material such as vinyl connected to the center of the integrally connected sheet is long, if the winding pipes placed on both sides of the house are not fixed, the covering material may shake or twist, making stable covering impossible. Accordingly, in order to stably hold the covering material without a binder string and prevent bending of the fixed winding pipe, various structures may be utilized, such as winding pipe fixing circular wheels that are placed at intervals of 3 to 5 m or more densely so that the upper part is open to allow the covering material to flow, or structures that hold the fixed winding pipe in a form that is open at the upper part to ensure smooth flow of the covering material. Accordingly, by installing fixed winding pipes and drive motors located at the lower ends of both sides of the house, and two movable winding pipes that move the full span from one side of the house to the other, and drive motors, the opening and closing of the covering material can be controlled.

Multi-sheets can be connected considering the characteristics of the ability to control the microclimate environment when growing house crops. That is, crops grow under the influence of light and temperature, and must be controlled to create appropriate environmental conditions. Therefore, on a clear day, when the sun first begins to rise until it sets, the temperature is not very high, and as time passes, it gradually increases, reaching its highest point around 2 p.m. and then gradually decreasing.

Therefore, the covering form of the shading material may vary depending on the case. For example, in the case of rain, the condition of not getting wet is a condition of covering the entire area with vinyl. At this time, when the temperature is somewhat high, the left and right side windows are opened appropriately so that rain does not flow into the house and ventilation is possible on both sides. In this case, when covering the entire area with one covering material, the entire area can be covered with each covering material. As an embodiment of the present invention, in the case of a connected integral covering sheet in which five types of sheets are connected, in addition to a form in which one type of covering material covers 100%, the entire area can be covered with up to four types of single covering materials, and up to 21 different covering forms can be used.

However, since most of the environmental control conditions are resolved by environmental control when managing crop cultivation with 2~3 types of covering materials, the benefits of covering with 4 types of covering materials for crop cultivation may not be great. In such cases, it may be acceptable to cover with a connected integral covering by connecting 3 types of covering materials.

For example, if the temperature is not very high and there is little shading, most of the upper part of the house can be covered with vinyl, one side can be covered with a large mesh netting that provides little shading and prevents snow from accumulating, and the other side can be covered with a low-rate shading netting that also repels insects. This will result in conditions almost identical to those in a vinyl house with the side windows open, so the side ventilation will be sufficient to control the temperature inside the facility.

Meanwhile, for covering the house to a completely open level, a net with a very low shading rate can be used, or if the insect repellent function is not considered, a net with a large mesh size (such as a bird net) can be used. In this case, a net with a mesh size that prevents snow from accumulating during winter snowfall can be used.

The method for opening and closing a house by winding various types of connected integral covering sheets of the present invention and the system thereof may be a connected integral sheet (100) in which five types of covering materials are connected in the order of high-rate shading net (10) - low-rate shading net (20) - vinyl (30) - insect/net (40) - medium-rate shading net (50), as shown in FIGS. 2, 3, and 4. Among these, the insect-proof net (40) may be an insect-proof net (41) of a height that can be used as a general side window of a house, and most of the rest may be a mesh net (42) with a large mesh. The above-mentioned connecting order of the covering materials is only an example, and they may be connected in various combinations and orders depending on the covering adjustment conditions.

Typical covering forms include insect repellent netting, which is covered with vinyl all over the field in case of rain or for insulation, a fully open-faced netting to prevent salt leaching by rain when crops are not being grown, to avoid damage from excessive wind or heavy snow during cultivation, or to prevent damage from snow when not growing crops during the winter off-season.

When the light is somewhat strong, a full-face low-rate shading net can be installed; when the light is stronger, a medium-rate shading net; and when the light is very strong and it is more necessary to suppress temperature rise to prevent damage from high temperatures rather than photosynthesis of crops, or to prevent seedlings from dying, or to improve the working environment when performing agricultural work unrelated to crop growth such as harvesting, three types of shading nets can be installed. Here, a low-rate shading net indicates a shading rate of 10 to 20%, a medium-rate shading net indicates a shading rate of 30 to 50%, and a high-rate shading net indicates a shading rate of 60% or more, indicating differences in shading rates. Sheets or insulating materials with various shading rates can be applied as needed.

In order to completely block the windward side in various environmental conditions, the windward side can be covered with vinyl and the upper part can be covered with netting or low-rate shading netting to allow light in. On the other hand, the upper part can be covered with high-rate shading netting or medium-rate shading netting, and one or both sides can be covered with netting or low-rate shading netting to allow ventilation and lower the temperature.

The above and below contents of the present invention are described for convenience of example, focusing on the covering of a greenhouse, which is a crop cultivation facility, and the method for opening and closing a greenhouse by winding various types of connected integral covering sheets and the system thereof can also be applied to various general facilities that require shading or opening and closing of covering materials other than agricultural ones.

The method for opening and closing a house by winding a variety of connected integral covering sheets of the present invention and the system thereof are described in detail with reference to the attached drawings, as follows, according to preferred embodiments.

As shown in FIGS. 2 and 3, it may be composed of a variety of covering materials including vinyl (30), a net (40) such as an insect screen, three or more types of shading nets (10, 20, 50) with different light blocking rates, a movable winding pipe (90) and a driving motor (91) located in the middle of the connecting sheet, and a fixed winding pipe (80) and a driving motor (81) located on the left and right sides of the house.

In addition, as shown in Fig. 5, it is composed of a solenoid lock (210) that connects a driving motor (200) and a winding pipe (240), a solenoid pin (211), a solenoid pin catch ring (212), and a driving motor and winding pipe connection socket (220), so that the winding pipe can be controlled to rotate freely above a certain load when winding a covering material.

Meanwhile, as the length of the house increases, the length of the winding pipe also increases. In order to prevent bending of the winding pipe, a fixed winding pipe fixed circular wheel (230) installed at regular intervals of 3 to 5 m and a plurality of position sensors can be installed to detect the position of the movable winding pipe, as shown in Fig. 12.

FIG. 6 is a perspective view showing only a detailed portion of a coiling pipe fixing circular wheel according to one embodiment of the present invention. The winding pipe fixing circular wheel (250) is a member that enables the covering material (300) to move without a fixing pad or binder string while horizontally fixing the winding pipe (310) located at the lower end of both sides of the house and allowing only minimal movement while restricting any further upward movement, and is a member that enables the covering material to be fixed without a fixing pad or binder string of the covering material. The member comprises a plurality of bearings (252) located on the inner wall of the circular wheel to minimize friction with the covering material wound on the winding pipe, a circular wheel opening (F in FIG. 6) that allows the covering material to move while restricting the movement of the upper part of the winding pipe, a detachable member (254) that enables the insertion of the winding pipe, a detachable member tightening bolt (256), a lower end of the house rafter (320) and an auxiliary vertical support member (330), an auxiliary cross member (340, 350), and a fixing member (360) that fixes the circular wheel (250).

In the house opening/closing method and system thereof by winding various types of connected integral covering sheets of the present invention, FIG. 12 is a schematic diagram showing an example of installation of a position sensor that can determine the current covering state in the step of covering various types of connected integral covering sheets according to one embodiment of the present invention. When the drive motor (931) of the movable winding pipe (930) and the fixed winding pipe (950) are rotated by the drive motor (951) to move the movable winding pipe, the position sensor (ls, rs) that can confirm the position can be a small magnetic contact sensor attached to one of the house rafters.

In addition, the position of the movable winding pipe can be specified by any other method, and since it is not actually required to set a precise position, the sensor can be attached to the required position. In general, taking an example of a general cultivation house, the position sensors are installed at 2 in the center of the roof (ls6, rs6), 2 on both sides of the skylight (ls5, rs5), 2 on both sides (ls4, rs4), 2 in the middle of the side windows (ls3, rs3), 2 at the bottom of the side windows (ls2, rs2), and the lower side (ls1, rs1), etc., and if 12 sensors are installed, it is possible to cover in as many as 21 types of covering forms as a connected integral covering sheet connected by 5 sheets, as shown in at least Figs. 2, 3, and 4. Of course, more detailed adjustment is possible if more position sensors are attached, but 12 sensors are sufficient considering the characteristics of crop cultivation and the greenhouse environment.

Meanwhile, as shown in Fig. 13, the current covering form can be determined by the operation signals of 12 position sensors and the rotational direction of the driving motor (931) of the movable winding pipe (930), and the covering form can also be changed into various forms by controlling the movement of the movable winding pipe.

At this time, the covering material is double-overlapped and wound when the driving motor (931) of the movable winding pipe (930) rotates forward and backward. The driving motor (951) of the fixed winding pipe (950) on the left and right lower sides can play a role in winding the covering material or pulling the covering material taut while winding it in place.

The fixed winding pipes at the bottom of both sides of the house are arranged in parallel on the side of the house by the fixed winding pipe fixed circular wheels attached at regular intervals, and when the covering material is wound by the operation of the winding pipe drive motor, the winding pipe moves upwards to the circular wheel, and the drive motor can be stopped by the limit switch or the drive motor inflow current overload sensor at the stage of moving upwards to the circular wheel.

This is because, when the covering is wound, a gap is provided to prevent damage to the covering due to malfunction. When the covering is completed, the lower fixed-type winding pipe is in contact with the upper part of the winding wheel. At this time, the covering is maintained taut. When the covering method is changed and one of the winding drive motors is to be operated, the pin of the solenoid lock of the fixed-type winding pipe on the side affected by the motor is disengaged and lowered below the winding wheel to freely rotate. Thus, the winding pipe goes down below the winding wheel due to gravity, and only when it contacts the lower limit sensor does the winding pipe drive motor in other positions operate. This prevents damage to the covering or malfunction of the driving motor. In addition, an overload sensor can be installed and operated on all drive motors so that they stop when there is unexpected damage to the covering or abnormal operation due to bending of the winding pipe.

FIG. 12 is a schematic diagram showing an example of installation of a position sensor that enables determination of the current covering state in a step of covering a variety of connected integral covering sheets according to an embodiment of the present invention, and FIG. 13 is a table for determining the covering state of a house according to a rotational direction signal of a driving motor of a position sensor and a movable winding pipe in an embodiment of the present invention.

In the present invention, a plurality of contact sensors capable of checking the position of a movable winding pipe can be installed. The contact sensors can automate the coating of a desired shape by stopping the driving motor of the movable winding pipe when the driving motor operates and reaches a contact sensor of a certain position. In addition, the current movable winding pipe can determine various combinations of coating shapes as shown in Fig. 13 according to the combination of the rotation direction signals of the contact sensors and the winding motor.

By placing the contact sensors in more locations like this, the shading shape and covering ratio can be changed accordingly. At this time, the position of the movable winding pipe can be confirmed by various types of sensors, such as a limit switch of the driving motor itself, a contact sensor by the movement of the driving motor, an ultrasonic sensor, etc., in addition to the magnetic contact sensor.

An example of applying a house opening/closing method and system by winding various types of connected integral covering sheets according to an embodiment of the present invention will be specifically described with reference to the drawings.

<Example 1> Vinyl Example of a front cover

Figure 7 is a schematic diagram showing a front vinyl covering type among various types of connected integral covering sheets according to one embodiment of the present invention. This covering type is a covering type generally used for insulation or when it rains.

As shown in FIG. 2, a multi-sheet integrated covering sheet (100) is connected in the order of high-rate shading net - low-rate shading net - vinyl - insect-proof net - medium-rate shading net. The connecting portions (B, C, D in FIG. 2) are connected by mutually joining the sheets to each other, and the medium-rate shading net (20) and vinyl (30) are connected by being fastened to a movable winding pipe (90a) on the left, and the vinyl (30) and insect-proof net (40) are connected by being fastened to a movable winding pipe (90b) on the right, and the left and right sides of the connected integrated sheet of these multi-sheets are fastened to a fixed winding pipe (80).

Each of these winding pipes is in the form of a covering material being wound by a winding pipe driving motor (81, 91). In FIG. 7, a movable winding pipe (430) is positioned on both sides of the lower part of the house with the covering material completely unwound. In addition, a fixed winding pipe (450a) located on the lower left side of the house is in the form of a roll (461) on which two types of sheets, a high-rate shading net (10) and a low-rate shading net (20), are both wound. A fixed winding pipe (450b) located on the lower right side of the house is in the form of a roll (462) on which two types of sheets, a medium-rate shading net (50) and an insect-proof net (40), are both wound. In the same covering form as the conventional vinyl-only covering of a vinyl greenhouse of FIG. 1, vinyl (400) can be completely covered on the rafters (410).

<Example 2> Example of full-face insect screen net covering

As an example of applying the method for opening and closing a house by winding the various types of connected integral covering sheets of the present invention and the system thereof, Fig. 8 is a schematic diagram showing a form in which a house is completely covered with a front insect screen. It is a representative covering form that can be taken to increase the inflow of light on a cloudy day when light is somewhat insufficient, to provide appropriate irrigation in case of rain, to remove contaminants by rain after crop cultivation, to prevent damage from typhoons and snow, and when not growing crops during winter.

In the multi-sheet connected integral covering sheet of the embodiments of FIGS. 2, 3, and 4, at the stage of changing from a vinyl front covering form (FIG. 7) to an insect repellent net front covering form (FIG. 8), the drive motor of the fixed winding pipe (550a) at the lower left of the house is briefly rotated to the left so that when the winding pipe reaches the bottom of the winding pipe fixed circular wheel (540a), the limit switch (not shown) operates to stop the drive motor, and then, as described above, the solenoid lock (210 of FIG. 5) is operated to release the binding so that the winding pipe can rotate freely.

In the next step, the drive motor of the movable winding pipe (530a) on the left is turned clockwise to wind the vinyl and low-rate shading net and move it to a position close to the movable winding pipe (530b) located on the right side of the house, and then the drive motor is stopped. Thereafter, the fixed winding pipe (50a) on the lower left side of the house and the drive motor are connected with a solenoid lock, and at the same time, the solenoid lock of the fixed winding pipe (450b) on the lower right side of the house is released as described above.

Then, when the drive motor of the fixed winding pipe (450a) at the lower left of the house is rotated clockwise, the high-rate shading net (10 in FIG. 2) is wound, and the left movable winding pipe (530a) in the form of a double roll (560) of low-rate shading net (20) and vinyl (30) and the right movable winding pipe (530b) with all of the covering materials released are pulled to the lower left of the house, and the insect screen net wound around the right lower fixed winding pipe (550b) is covered. At this time, when the left movable winding pipe (530a) and the right movable winding pipe (530b) that were being pulled are tilted to the left beyond the ridge of the house roof, movement due to free fall may occur, so that the fixed winding pipe at the lower right may include a member that does not rotate under a certain load to prevent this.

In the next step, when the movable winding pipe (530a) on the left side of the house reaches the proximity position sensor of the fixed winding pipe (550a) on the lower left side of the house, the drive motor of the fixed winding pipe on the left side stops. Thereafter, the solenoid lock of the fixed winding pipe (550b) on the lower right side of the house is engaged, and the drive motor is rotated to the left so that the fixed winding pipe on the lower right side (550a) stops when it contacts the upper limit switch of the right circular fixed wheel (540b), or when a certain amount of load is applied and the covering material becomes taut, the drive motor is stopped by the current detection sensor, thereby completing the covering.

In the case of changing back to the vinyl front cover after sunset, the same system operation method as described above is followed. First, the drive motor of the fixed winding pipe (550a) on the lower left of the house is briefly rotated to the left to loosen the cover material, and the solenoid lock is operated to release the connection between the drive motor and the winding pipe so that they can rotate freely. Then, the drive motor of the fixed winding pipe (550b) on the lower right of the house is rotated to the left to pull the net, so that the high-rate shading net (10 in FIG. 2) wrapped around the fixed winding pipe (550a) on the lower left is covered, and when all the movable winding pipes move to a position close to the fixed winding pipe (550b) on the lower right, the drive motor of the fixed winding pipe (550b) on the lower right is stopped. In the next step, the solenoid lock of the left lower fixed winding pipe (550a) and the driving motor is connected, the solenoid lock of the left movable winding pipe (530a) is dismantled, and the driving motor of the left lower fixed winding pipe (550a) is turned clockwise to wind all the high-rate shading nets (10 in FIG. 2), and then the low-rate shading nets (20 in FIG. 2) are wound, and when the left winding pipe (530a) reaches the position of the left lower fixed winding pipe (550a) proximity contact sensor, the driving motor of the left lower fixed winding pipe (550a) is stopped.

Then, the solenoid lock of the left movable winding pipe (530a) is connected, and then the drive motor of the left lower fixed winding pipe (550b) is turned clockwise so that the left fixed winding pipe (550a) stops when it contacts the limit switch at the upper position of the left circular winding wheel (540a), or when the covering material becomes somewhat taut and a load is applied to the driving motor, the driving motor can be stopped by the current detection sensor. After a series of processes, the embodiment of the full-face covering of the insect repellent net (500) is completed.

As described above, in this process, when the movable winding pipe (530a) on the left passes the ridge of the house and goes to the left, the winding pipe (530a) may move freely due to potential energy. To prevent this, the fixed winding pipe (550b) on the lower right may include a member that does not rotate under a certain load.

<Example 3> Example of full-face covering with low-rate shading net

As an example of applying the method for opening and closing a house by winding a variety of connected integral covering sheets of the present invention and the system thereof, FIG. 9 is a schematic diagram showing a form in which a house is completely covered with a low-rate shading net, which is a covering form that can be taken when the light is slightly high.

When changing the covering material to a low-rate shading net (600) at the stage of vinyl full-coverage (100%), first, briefly turn the drive motor of the fixed winding pipe (650a) on the lower right to the right so that it comes into contact with the lower part of the fixed circular wheel (640a) of the fixed winding pipe on the right, and when the covering material becomes loose, release the solenoid lock to make it rotate freely.

Next, the driving motor of the right-hand movable winding pipe (630b) is rotated to the left so that the vinyl and insect repellent net (660) overlap and are wound around the pipe, thereby moving the right-hand movable winding pipe (640b) to a position close to the left-hand movable winding pipe (640a).

Afterwards, the solenoid lock of the lower right fixed winding pipe (650b) is connected, the solenoid lock of the lower left fixed winding pipe (650a) is disengaged, and the lower right fixed winding pipe (650b) is then turned to the left to wind the medium-rate shading net (672) and the left and right movable winding pipes (630a, 630b) are pulled until the low-rate shading net (600) is covered and when the left and right movable winding pipes (630a, 630b) reach a position close to the lower right fixed winding pipe (650b), the drive motor of the lower right fixed winding pipe (650b) is stopped.

Next, the solenoid lock of the driving motor of the lower left fixed winding pipe (650a) is connected, and then the motor of the lower right fixed winding pipe (650b) is rotated to the left to stop the driving motor when it reaches the limit switch on the upper part of the circular winding wheel (640b).

<Example 4> Example of low-rate shading net-vinyl-insect net covering

As an example of applying the method for opening and closing a house by winding various types of connected integral covering sheets of the present invention and the system thereof, FIG. 10 is a schematic diagram showing a form in which the left side of the house is covered with a low-rate shading net, the right side with an insect-proof net, and the upper side with three types of covering materials, including vinyl.

This is a covering type that aims to maintain heat on days when the internal temperature of the house does not rise very much. The upper part is covered with vinyl and the sides are covered with a shading net to ensure adequate ventilation; in other words, this is a covering condition that is generally suitable for conditions in which ventilation is allowed to occur and the temperature is lowered appropriately. This covering condition is similar to the case where the side windows are opened in a conventional vinyl house as shown in Fig. 1, and since both side windows are covered with a shading net and an insect-proof net, this is a covering type that can minimize the inflow of pests.

When vinyl starts from the full-coverage (100%) stage and changes to the covering material of low-rate shading net-vinyl-insect net, the left lower fixed winding pipe (750a) briefly turns the driving motor to the left to loosen the tension of the covering material and then releases the solenoid lock. Then, the driving motor of the left movable winding pipe (730a) is turned to the right to wind the vinyl (700) while the low-rate shading net (701) covers the left side of the house and when it reaches a certain height position, the driving motor is stopped. Thereafter, the solenoid lock of the left lower fixed winding pipe (750a) is engaged and the driving motor is turned to the right to stop the driving motor when the left fixed winding pipe (750a) comes into contact with the upper limit of the circular wheel (740a).

Similarly, the drive motor of the fixed winding pipe (750b) on the lower right is turned clockwise for a moment to loosen the tension of the covering material, and then the solenoid lock is released. Next, the drive motor of the movable winding pipe (730b) on the right is turned counterclockwise to wind the vinyl (700) while the insect screen (702) covers the right side of the house, and when it reaches a certain height, the drive motor is stopped.

After that, the solenoid lock of the lower right fixed winding pipe (750b) is engaged and the driving motor is rotated to the left so that when the right fixed winding pipe (750b) comes into contact with the upper limit of the circular wheel (740b), the driving motor is stopped.

<Example 5> Example of covering with 50% low-rate shading net and 50% insect-proof net

As an example of applying the method for opening and closing a house by winding a variety of connected integral covering sheets of the present invention and the system thereof, FIG. 11 is a schematic diagram showing a form in which one side of a house is covered with a low-rate shading net and the other side is covered with an insect-proof net, which is a covering form suitable for shading the left side and ensuring sufficient ventilation on a day when the morning sunlight is excessively strong.

When the vinyl starts from the full-coverage stage and changes to a 50% low-rate shading net - 50% insect repellent net covering form, the drive motor of the fixed-type winding pipe (850a) on the lower left is briefly turned to the left to loosen the covering material, the solenoid lock is disengaged to allow the pipe to rotate, the drive motor of the movable-type winding pipe (830a) on the left is turned to the right to move to the center of the house, the drive motor is stopped, and the solenoid lock of the fixed-type winding pipe (850a) on the lower left is engaged.

Similarly, the drive motor of the fixed-type winding pipe (850b) at the lower right is turned clockwise for a moment to loosen the covering material, disengage the solenoid lock and allow the pipe to rotate, then the drive motor of the movable-type winding pipe (830b) at the right is turned counterclockwise to move to the center of the house, then the drive motor is stopped and the solenoid lock of the fixed-type winding pipe (850b) at the lower right is engaged.
