Description

{Laver Farming System on Land}

The present invention relates to a seaweed cultivation device or a seaweed cultivation system for cultivating seaweed.

Kim is farmed in coastal waters, and is mainly farmed by floating long nets on the sea surface. In Korea, due to climate conditions, farming is possible between November and March of the year, and harvesting occurs two to three times a month.

However, there are many cases where nets and buoyancy devices for laver farming are lost due to typhoons. In addition, microplastics are also found in laver produced due to the effects of ocean pollution such as microplastics.

Kim is mainly farmed on the southern coast where the calm sea spreads out, but as water temperatures gradually rise due to climate change, Kim farming on the southern coast is also affected, and the production of Kim per unit area is decreasing.

The purpose of the present invention is to provide a seaweed farming system that is not affected by the marine environment.

Another object of the present invention is to provide a seaweed cultivation system capable of cultivating seaweed all year round.

A land-based laver aquaculture system according to one aspect of the present invention is characterized by including: a seaweed net holder for placing a long single seaweed net in a zigzag manner back and forth between one side and the other; a sprinkler array in which sprinklers are arranged in an array to spray seawater and nutrient solution toward the seaweed net placed on the seaweed net holder; and an LED light array in which LED lights are arranged in an array to irradiate light simulating sunlight toward the seaweed net placed on the seaweed net holder.

FIG. 1 is a side view illustrating a seaweed farming system according to a first embodiment of the present invention, and FIG. 2 illustrates a seaweed net holder in a seaweed farming system according to the first embodiment of the present invention.

The laver cultivation system according to the first embodiment of the present invention is a system for cultivating laver on land, and is configured to include a seaweed net holder (1), a sprinkler array (21:21a, 21b, 21c), an LED light array (22:22a, 22b), a blower array (23:23a, 23b), a water receiver (24), a tank (27), a filter (25), and a pump (26).

The seaweed net holder (1) is used to hold a long single seaweed net (net) (M) as in seaweed farming. In order to maximize space efficiency, the seaweed net is held in a zigzag manner between one side and the other. When performing laver farming, the seaweed net with laver spores collected is held on the seaweed net holder (1), and harvesting and holding are more conveniently performed by using a long seaweed net. Considering that the seaweed net holder (1) is directly exposed to salt water, it is preferred to be made of stainless steel.

A sprinkler array (21: 21a, 21b, 21c), an LED light array (22: 22a, 22b), and a blower array (23: 23a, 23b) are configured around a seaweed net stand (10). The sprinklers (21a, 21b, 21c) spray seawater or seawater mixed with a nutrient solution (hereinafter, may be simply referred to as “seawater”) toward a seaweed net mounted on a seaweed net stand (1). The sprinklers are positioned to be distributed on the side (see 21a, 21b) and top (see 21c) of the seaweed net stand so that the seawater and nutrient solution can be sprayed as evenly as possible over the entire seaweed net mounted on the seaweed net stand (1). A plurality of sprinklers configured on the side and top are arranged in an array to configure a sprinkler array. Nutrients can be mixed and sprayed with purified seawater supplied from a well on land near the sea, and the sprinkler can spray over a designated area by moving up, down, left, and right.

The LED light (22a, 22b) is a light source using an LED element, and irradiates light simulating sunlight toward the fishing net mounted on the fishing net stand, and may be composed of a single or multiple LED elements that generate light containing white light, ultraviolet light, and infrared light. The LED lights are configured innumerable times on the side of the fishing net stand, and may also be configured further on the upper surface of the fishing net stand, so that the entirety of the LED light array is configured. In addition, the LED lights may be installed directly on the fishing net stand to improve light efficiency, and may be installed directly on frames such as vertical frames (11a, 11b, 11c) and horizontal frames (11d, 11e), and may have packaging applied that is waterproof from seawater sprayed from a sprinkler.

The blowers (23a, 23b) are installed on the sides of the fishing net stand and blow wind toward the fishing nets installed on the fishing net stand, simulating the wind in a marine environment. Of course, the sprinklers, LED lights, and blowers can be additionally installed on other sides as well as the two sides of the fishing net stand, and the LED lights and blowers can also be additionally installed on the upper side of the fishing net stand.

The water receiver (24) collects and reuses the seawater sprayed by the sprinkler that has wetted the seaweed net and then fallen. It can be collected in a tank (27) or directly supplied to the sprinkler using a pump (26). The filter (25) filters the supplied seawater to filter out foreign substances, especially microplastics and tidal flat debris, so that clean seawater can be supplied to the laver being farmed. Seawater supplied from a well on land near the sea is first filtered by sand, but is secondarily filtered by the filter (25), and furthermore, fine dust or pollutants in the environment captured by seawater during farming are filtered. The pump (26) receives seawater from the tank (27) through the filter (25) using a pipe, is connected to the sprinkler using a pipe, and pumps the seawater so that it can be sprayed (sprayed) by the sprinkler.

Haetae Net grows laver only in an air-conditioned environment without submerging it in a tank or the like. In addition, seawater and nutrient solution are circulated and reused using a water catcher and sprinkler.

According to the laver cultivation system according to the present invention, laver can be cultivated on land, so it has the effect of enabling laver cultivation all year round without being affected by the marine environment. In particular, according to the laver cultivation system according to the present invention, it has the effect of enabling large-scale laver cultivation on land by spraying (spraying) seawater and using LED light simulating sunlight (or adding wind).

The seaweed net support of the seaweed farming system according to the first embodiment of the present invention comprises a frame including vertical frames (11a, 11b, 11c) and horizontal frames (11d, 11e), a left roller array including a plurality of left rollers (L1 to L11), a right roller array including a plurality of right rollers (R1 to R11), and a middle roller array including a plurality of middle rollers (C1 to 11).

The frame is composed of vertical frames (11a, 11b, 11c) and horizontal frames (11d, 11e), and forms the skeleton of the fishing net stand, and allows various rollers to be installed. For example, as shown in Fig. 2, the vertical frame may be formed by a left vertical frame (11a), a right vertical frame (11b), and a middle vertical frame (11c) being installed vertically to the ground, and a horizontal frame connecting them to form a hexahedron. The horizontal frame is installed horizontally between the vertical frames, and is composed of an upper horizontal frame (11d) and a lower horizontal frame (11e).

The left rollers (L1 to L11) are rollers installed horizontally on the frame so as to rotate in place on the left side of the frame. A plurality of left rollers are arranged in an array while being spaced apart from each other in the vertical direction to form a left roller array. The left roller is rotatably supported by two vertical frames (11a) on the left side.

The right roller (R1 to R11) is a roller installed horizontally on the frame so as to rotate in place on the right side of the frame in the fishing net support, and a number of right rollers are arranged in an array while being spaced apart from each other in the vertical direction to form a right roller array. The right roller is rotatably supported by two vertical frames (11b) on the right side.

The intermediate rollers (C1 to C11) are a plurality of rollers that rotate in place in the middle between the left and right sides of the frame. A plurality of intermediate rollers are arranged in an array while being spaced apart vertically to form an intermediate roller array. The intermediate rollers are supported so as to be rotatably horizontally by two intermediate frames (11c) in the middle.

The seaweed net (M) is sequentially moved back and forth between the two left rollers in the left roller array and the two right rollers in the right roller array, thereby zigzagging between one side (left) and the other side (right) of the seaweed net stand. The seaweed net (M) mounted on the seaweed net stand (1) is a single long mesh net that vertically forms a number of layers (a total of 11 layers in the city) from the bottom to the top. When the seaweed net changes layers, it is made to span two rollers. By spanning two rollers in this way, a certain amount of vertical space is secured between the seaweed nets of the adjacent layers, thereby securing a certain amount of space for the seaweed to grow.

The first layer's net is connected to the second layer's net after being spanned by two right rollers (R10, R11) spaced apart at a regular interval. The second layer's net is connected to the third layer's net after being spanned by two left rollers (L9, L10) spaced apart at a regular interval. The third layer's net is connected to the fourth layer's net after being spanned by two right rollers (R8, R9) spaced apart at a regular interval. In this manner, the nets of all layers are interconnected in a zigzag shape by alternately moving back and forth across the rollers formed on the left and right sides.

Ropes (B1, B2) are connected to both ends of the seaweed net (M), and by tying these ropes to a frame, etc., the positions of the two ends of the seaweed net can be fixed during seaweed cultivation. In addition, when the seaweed is to be harvested, the ropes (B1, B2) can be released, and the seaweed net can be transported to the seaweed harvesting device. For example, the rope (B1) is used to pull the entire seaweed net in the direction of P1 so that the seaweed net gradually passes the seaweed harvesting device (not shown) to harvest seaweed. The length of the rope (B2) is longer than the entire length of the seaweed net, so that when the seaweed net is moved toward the seaweed harvesting device, the rope (B2) is sequentially placed on the rollers instead of the seaweed net, starting from the roller at the top. When the seaweed harvesting by the seaweed harvesting device is completed, the rope (B2) is now pulled in the direction of P2 so that the seaweed net is placed on the seaweed harvesting device holder as shown in FIG. 2, and returned.

A rope guide groove (T) is formed along the circumference of the central portion of the left roller and the right roller to guide the rope. When the seaweed of the seaweed net is transported to be harvested, the rope (B2) can be sequentially placed on the rollers of the stand, and a rope guide groove (T) can be formed to allow the rope to be hung on the central portion of each roller.

According to the seaweed net holder of the first embodiment of the present invention, there is an effect of greatly simplifying the process of harvesting after seaweed cultivation is completed and the process of placing the seaweed net again.

Fig. 3 illustrates a seaweed net holder used in a seaweed farming system according to a second embodiment of the present invention. The seaweed farming system according to the second embodiment of the present invention is identical to the seaweed farming system according to the first embodiment of the present invention in terms of its surrounding components, except for the seaweed net holder, and therefore, a description thereof will be omitted.

A fishing net stand (2) according to a second embodiment of the present invention is configured to include a frame (12a, 12b, 12c, 12d, 12e) that serves as a skeleton, a fixed roller array composed of a plurality of rollers (U1 to U11), and a movable roller array composed of a plurality of movable rollers (D1 to D9).

The seaweed net holder (2) according to the second embodiment of the present invention is the same as the seaweed net holder of the first embodiment in that it holds a single seaweed net of a long length in a zigzag manner back and forth between one side (upper side) and the other side (lower side), but differs in several points, such as the direction of holding. The seaweed net is moved back and forth between one side (upper side) and the other side (lower side) in a zigzag manner by sequentially moving one fixed roller from the fixed roller array and one moving roller from the moving roller array alternately.

The frame is configured by integrally combining a pair of left frames (12) that are vertically installed relative to the ground, a pair of right frames (12b) that are vertically installed with a certain width therebetween, a pair of middle frames (12c) that are vertically installed between the left and right frames, an upper frame (12d) that is joined to the upper ends of the left frame, the middle frame, and the right frame, and a lower frame (12e) that is joined to the lower ends of the left frame, the middle frame, and the right frame.

The fixed rollers (U1 to U11) are hung on the upper side of the frame so that both ends can rotate in place on the upper frame, and a plurality of fixed rollers are arranged in an array while being horizontally spaced apart to form a fixed roller array.

The moving rollers (D1 to D9) are mounted on the lower side of the frame or on the upper side of the frame, and can be moved to one of two positions. They can be rotated in place with both ends hanging over the lower frame, or moved upward and rotated in place. A plurality of moving rollers are arranged in an array while being spaced apart in the horizontal direction to form a moving roller array. The moving rollers can be rotated with both ends hanging over the hooks (13a) installed on the upper frame. In addition, the moving rollers can be rotated with both ends guided by the shaft guides (13b) installed on the upper surface of the lower frame. Such movement of the moving rollers can be performed by a user (manpower).

For example, when forming a seaweed, each moving roller of the moving roller array is located at the lower side of the frame as shown in Fig. 3, and specifically, is guided by the shaft guide (13b). Although not shown, a locking means may be further included to prevent the shaft of the moving roller located within the shaft guide (13b) from moving upward. The locking means may be in various forms, such as a locking form that closes the opening of the shaft guide (13b), or a means that can switch the opening and closing of the opening by a push button.

Meanwhile, when the cultivated seaweed is to be harvested, the user moves each movable roller of the movable roller array to the upper side of the frame so that both ends thereof are placed on the mounting hooks (13a). Accordingly, the movable rollers are fixed so that they can rotate in place at a position very close to the fixed roller. Accordingly, when one end of the seaweed net is pulled in the direction of P1 using the rope (B1) to send the seaweed net to the seaweed harvesting device, the work of pulling the seaweed net becomes easier. In addition, the length of the rope (B2) can be much shorter than in the first embodiment. Meanwhile, after the harvesting is completed, the rope (B2) is appropriately pulled and then fixed, and the movable rollers that have been moved upward and placed are sequentially lowered starting from the movable roller (D9) at the end and placed inside the shaft guide (13b).

In the above, it has been described that the lower rollers can move in position, as indicated by the name of the 'moving roller', but similarly to the first embodiment, the lower rollers may also be fixed to the lower side (to the lower frame).

In addition, in the embodiment of Fig. 3, the net is configured to form a zigzag shape by sequentially moving up and down one fixed roller from the fixed roller array and one moving roller from the moving roller array alternately, but a configuration is also possible in which a zigzag shape is formed by sequentially moving back and forth two fixed rollers and two moving rollers alternately, or two for only one of them.

FIGS. 4 and 5 illustrate a seaweed net holder used in a seaweed farming system according to a third embodiment of the present invention. FIG. 4 is a front view and FIG. 5 is an enlarged perspective view of part A in FIG. 4.

The seaweed farming system according to the third embodiment of the present invention is identical to the seaweed farming system according to the first embodiment of the present invention in terms of its surrounding components, except for the seaweed net holder, and therefore, a description thereof is omitted.

And the fishing net stand according to the third embodiment of the present invention has a frame structure similar to the second embodiment, and the frame is configured by integrally combining a pair of left frames (14a) that are vertically installed with respect to the ground, a pair of right frames (14b) that are vertically installed with a predetermined width therebetween, a pair of middle frames (14c) that are vertically installed between the left and right frames, an upper frame (14d) that is coupled to the upper ends of the left frame, the middle frame, and the right frame, and a lower frame (14e) that is coupled to the lower ends of the left frame, the middle frame, and the right frame.

In the third embodiment, a crossbar (30) that crosses the width of the net (M) is uniquely attached at regular intervals, so that the crossbar (30) is fixed to the net. For example, the crossbar (30) can be fixed to the net using a short, thin rope. Accordingly, when the net is transported for harvesting, it can be transported together with the crossbar (30).

The upper side of the Haetaenet support is provided with a pair of parallel support beams that extend horizontally and are spaced apart from each other in the width direction, and both ends of the above-described crossbar (30) can be supported on these support beams. In the third embodiment, the above-described upper frame (14d) performs the role of the support beam, and therefore, the same symbol 14d is used for the support beam hereinafter.

When forming seaweed, both ends of the crossbar (30) are placed on a pair of support beams (14d), but the adjacent crossbars (30) are placed with a gap between them, and the seaweed net between them is hung downward, so that a single seaweed net of a long length is placed in a zigzag manner between the upper and lower sides.

In order to maintain the state in which the crossbars (30) are placed at regular intervals, a position fixing means (15) is used. The fishing net stand (3) further includes a position fixing means (15) that fixes the position of the crossbars (30).

The position fixing means (15) may be configured as a pair of means (15a, 15b) in the shape of a diagonal line or a ring, one end of which is rotatably connected to the side of the mounting beam (14d) using an axis (K1, K2). This position fixing means has a body in the shape of a diagonal line or a ring, and one end of which is rotatably connected to the mounting beam using two axes (K1, K2) spaced apart from each other on the left and right.

For example, when it is desired to fix the position of the crossbar (30), the position fixing means is rotated so that the two main bodies in the shape of a letter or a ring surround one end of the crossbar (30) from above. The position fixing means fixes the crossbar to both ends of the crossbar, thereby restricting the movement in the left-right direction on the support beam (14d) and fixing the position. Meanwhile, the movement in the forward-backward direction is restricted because the net is caught between the two support beams (upper frame).

Meanwhile, when transporting the seaweed net for harvesting laver, the position fixing means is rotated to allow free left-right movement of the crossbar (30). When allowing movement of the crossbar on the support beam, each position fixing means is rotated in the opposite direction to the direction in which it was rotated for fixation. When hanging in a free state after rotation, as shown in Fig. 5(b), the uppermost part of the position fixing means is prevented from protruding above the upper surface (the sliding surface on which the crossbar slides) of the support beam (14d). Accordingly, the crossbar fixed to the seaweed net and transported to the laver harvesting device can freely move (slide) left-right without interference from the position fixing means.

In the above, it was stated that one crossbar is installed at regular intervals, but two crossbars may be installed as a pair at close intervals and mounted on a support beam.

According to the seaweed net holder of the third embodiment according to the present invention, there is an effect in which the fixing force for the seaweed net can be strengthened during seaweed cultivation, and further, when harvesting seaweed, the load reduction due to not using a roller is greater than the load increase due to the weight of the crossbar, so there is an advantage in which the pulling force can be further reduced.
