Description

Hydroponic system using round flat-plate cultivation frame and pot lid {The hydroponic system}

The present invention relates to a hydroponic cultivation system using a round flat-plate cultivation frame and a pot lid.

In general, hydroponics refers to a cultivation method in which plants are grown in a nutrient solution (culture solution) containing water and various nutrients necessary for plant growth under an artificial light source.

According to hydroponics, unlike the usual case of growing plants outdoors or in a greenhouse, the growing environment of plants can be controlled relatively easily, so not only can clean vegetables or crops be harvested without contamination because pesticides harmful to the human body are not used, but the growing period of crops can be shortened, so a large harvest can be obtained in a short period of time.

Conventional hydroponics have been carried out in solar-powered facilities such as vinyl houses or greenhouses, but recently, plant cultivation machines or plant factories have been developed that allow crops to be grown regardless of the season or location without the occurrence of pests and diseases by artificially controlling environmental conditions such as light, temperature, humidity, carbon dioxide concentration, and nutrient solution in facilities isolated from the outside.

A large-scale plant cultivation facility can be called a plant factory, so from now on it is simply called a plant cultivation facility.

Since plant cultivation machines are usually operated indoors, artificial light sources such as incandescent lamps, fluorescent lamps, or LEDs are used. One of the major advantages of plant cultivation machines is that the cultivation period of crops can be significantly shortened by irradiating the optimal cycle of light of wavelength and intensity suitable for crop growth through the use of these artificial light sources.

However, there is a problem that the temperature inside the plant cultivation device rises excessively by using multiple artificial light sources in a closed space. For example, general lighting fixtures such as fluorescent lamps or incandescent lamps generate heat and light together, and in the case of LEDs, light goes out in front, but heat is generated at the back and directed into the inside of the module, so the internal heat is discharged to the outside (plant factory space) by a certain heat dissipation structure. However, since a plant cultivation device uses relatively high-density artificial lighting, the temperature inside the plant cultivation device increases as a result, which is a problem.

In the case of existing plant cultivation equipment, the temperature of the culture medium is not cooled to the optimum growth temperature of 20~25℃, which causes necrosis in the heat of summer. In other words, as the temperature of the culture medium rises and the amount of dissolved oxygen required for plant growth decreases, the roots of the plants rot.

Therefore, it is common for conventional plant cultivation equipment to have a separate cooling system, such as an air conditioner, to control the internal temperature.

Patent Publication No. 10-2011-0071636 proposes a system for efficiently cooling an LED lighting device by forming a water cooling pipe of a specific structure in an LED heating device and installing a circulating water cooling device. Patent Publication No. 10-2012-0015684 discloses a structure for cooling the heat generated from an LED lighting device by circulating a hydroponic culture solution stored in the tray by closely attaching an LED substrate to the bottom of a plant tray. However, these technologies are not only complicated in terms of system, but also require a separate cooling system for controlling the temperature of the internal space of a plant factory because they are intended to prevent the temperature of the lighting device itself from rising.

In addition, patent publications No. 10-2004-0010426 and 10-2012-0041538 describe installing a cooling fan on one side to prevent excessive temperature rise or providing a duct to supply air to control temperature and humidity.

However, when the plant cultivation device becomes larger, it is not possible to control the temperature rise inside the plant cultivation device through simple air circulation or air supply.

Patent registration No. 10-1222399 discloses a hydroponic cultivation device equipped with a cooler consisting of a conventional compressor, condenser, expansion valve, etc. According to this, although the temperature control of the plant cultivation device is smooth, there is a disadvantage in that the production cost of crops increases as the amount of electricity used increases. That is, even if it is a plant cultivation device with a cooling system for the nutrient solution (compressor, thermoelectric cooling), it consumes a lot of energy to cool the appropriate temperature required for plant cultivation.

In addition, a plant cultivation machine with a separate cooling system cools the culture medium regardless of the surrounding environment (temperature/humidity), so condensation occurs in the tank and flow path of the cooled culture medium. To prevent this, a separate condensation prevention component must be configured, making the system more complex.

To solve these problems, a technology using vaporization cooling is disclosed in Korean Patent Publication No. 2015-0071834.

However, these prior arts are complex structures including an vaporizing filter that absorbs water while allowing air to pass through; a water supply unit that supplies water to the vaporizing filter; and one or more blowers that allow air to pass through the vaporizing filter, wherein the water supply unit is composed of a pump that supplies water to the upper surface of the vaporizing filter and a water supply pipe.

The purpose of the present invention is to provide a hydroponic cultivation system using a round flat-plate cultivation frame and a pot lid that can solve conventional problems.

According to one embodiment of the present invention for solving the above problem, a cultivation system using a round flat-plate cultivation frame and a pot lid comprises: a water tank; a multi-stage cultivation frame in which a hemispherical cultivation frame, a flat-plate cultivation frame, and a cylindrical cultivation frame are sequentially arranged and laminated at preset intervals, and perforated holes having different diameters are formed on the surfaces of each cultivation frame; a pump unit positioned in the water tank and supplying water in the water tank at a preset pressure through a two-channel pump pipe; a water supply pipe inserted into the hollow of the multi-stage cultivation frame, having a spray nozzle attached to an upper end, and a lower end connected to one of the two-channel pump pipes; and a water supply pipe rotating unit that rotates the water supply pipe with water pressure supplied from the other of the two-channel pump pipes, wherein the perforated holes are holes into which a cultivation sponge is inserted, which is provided with artificial soil on a surface, has a micro-mesh for accommodating seeds, has a Velcro attached to one end, and is manufactured so as to be able to be rolled into a cylindrical shape.

In one embodiment, the cylindrical re-grinding member is characterized by including a buoyancy material therein to provide buoyancy within the tank.

In one embodiment, the water supply pipe is characterized by including a circular fastening ring pressurized and fastened to the hollow portion of the multi-stage rearrangement frame.

In one embodiment, the water supply pipe rotating member is characterized by having a cylindrical frame connected to the lower end of the water supply pipe within the hollow space; and web panels arranged at a predetermined interval on the side of the cylindrical frame and arranged at a preset inclination angle.

Therefore, by using a cultivation system using a round flat-plate cultivation frame and a pot lid according to one embodiment of the present invention, there is an advantage in that various plants can be hydroponically cultivated by changing their positions in a multi-tier cultivation frame according to growth.

Hereinafter, with reference to the attached drawings, preferred embodiments will be described in detail so that those with ordinary skill in the art can easily practice the present invention. However, when describing preferred embodiments of the present invention in detail, if it is determined that a specific description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. In addition, the same reference numerals are used throughout the drawings for parts that perform similar functions and actions.

In addition, throughout the specification, when a part is said to be 'connected' to another part, this includes not only the case where it is 'directly connected' but also the case where it is 'indirectly connected' with another element in between. Also, 'including' a component means that it can include other components rather than excluding other components unless specifically stated otherwise.

Hereinafter, a cultivation system using a round flat-plate cultivation frame and a pot lid according to one embodiment of the present invention will be described in more detail based on the attached drawings.

The above multi-stage rearrangement frame (110) is configured with hemispherical and flat-plate rearrangement frames arranged vertically at regular intervals, and each rearrangement frame has multiple punching holes of different sizes formed therein.

As a hole for inserting the above cultivation sponge, the cultivation sponge may be configured to be provided with artificial soil and manufactured to accommodate seeds. The cultivation sponge is configured to be formed with a micro-network to form a micro-space capable of accommodating seeds, and to be manufactured to be rolled into a cylindrical shape by attaching Velcro to one end. The cultivation sponge rolled into a cylindrical shape is inserted into the perforated hole of each cultivation frame.

The above cultivation sponge has Velcro attached, so when rolled up, it becomes a snail shape due to the Velcro, so even if seeds are inserted, they will not fall out or come off. As the plants grow, the velcro can be removed to expand the space according to their size.

Therefore, by manufacturing the perforation holes of the cultivation frame differently, when used for sprouting purposes, as the sprouts grow, the snaps can be removed to secure space and then moved to a cultivation frame with larger perforation holes, and even when the sprouted plants grow, there is an advantage in that the cultivation sponge can be used as is without replacing it.

Meanwhile, the multi-stage cultivation frame (110) can be composed of a hemispherical cultivation frame, a flat-plate cultivation frame, and a cylindrical cultivation frame, and the hemispherical cultivation frame (111) is manufactured in the shape of a pot lid, and a stand for mounting on a water supply pipe (120) described later is provided at the bottom.

The flat-plate type rearrangement frame (112) is manufactured in a flat-plate shape and has a plurality of perforated holes formed on the surface. In addition, the flat-plate type rearrangement frame (112a) is configured with a buoyancy material and is located at the very bottom of the multi-stage rearrangement frame (110).

The cylindrical cultivation frame (113) is provided with a partition frame to classify the plants to be cultivated, and a plurality of perforated holes are formed on the upper surface and/or the lower surface.

Meanwhile, the multi-stage cultivation frame (110) may further include a flower pot holding net (a) that can hold flower pots between cultivation frames.

The above flowerpot holding network (a) may be a structure in which multiple flowerpot holding holes are connected, such as an artificial neural network or tree branches.

Next, the water supply pipe (120) may be a pipe for moving water pumped from the pump unit (160) described later upward.

In addition, the water supply pipe (120) functions to secure the multi-stage rearrangement frame (110) described above.

Next, the injection nozzle part (130) may be configured to be connected to the upper end of the water supply pipe (120) and spray water supplied from the water supply pipe (120) in a certain direction or radially.

Next, the lighting unit (140) may be configured to be installed in a water supply pipe between a hemispherical rearrangement frame (111) and a flat-plate rearrangement frame (112) and irradiate preset light.

Next, the water supply pipe rotation part (150) may be configured to rotate the water supply pipe (120) in one direction, and may be configured to rotate at a preset water pressure in the pump part (160) described later. The water supply pipe rotation part (150) may have a shape similar to a water mill.

The above water supply pipe rotating part (150) may be provided with a cylindrical frame connected to the lower end of the water supply pipe within the hollow space and web panels arranged at a predetermined angle of inclination at a set interval on the side of the cylindrical frame.

Next, the pump unit (160) may be configured to supply water in the tank to the water supply pipe rotation unit (150).

Therefore, the water supply pipe rotation part (150) can rotate the water supply pipe (120) in one direction with the water pressure supplied from the pump part (160).

In addition, a hydroponic cultivation system using a round flat-plate cultivation frame and a pot lid according to one embodiment of the present invention may further include a rotating support.

The above-mentioned rotary support may be configured to prevent the water supply pipe from shaking. In the present invention, a cross-shaped structure is exemplified, but any shape that prevents the water supply pipe from shaking may be used.

Therefore, by using a cultivation system using a round flat-plate cultivation frame and a pot lid according to one embodiment of the present invention, there is an advantage in that various plants can be hydroponically cultivated by changing their positions in a multi-tier cultivation frame according to growth.

As described above, although a specific description of the present invention has been made by means of embodiments with reference to the attached drawings, the above-described embodiments have only described preferred examples of the present invention, and therefore the present invention should not be understood as being limited to the above-described embodiments. Therefore, in addition to what has been described above, a person having ordinary knowledge in the technical field to which the present invention pertains will be able to easily implement other forms of the present invention within the same category as the above-described embodiments, or implement inventions in an equivalent field to the present invention, only with the description of the embodiments of the present invention.
