Description

【Technical Field】 【0001】 The present invention relates to a hydroponic cultivation panel and hydroponic cultivation equipment. 【Background Art】 【0002】 Hydroponic cultivation is known in which a panel is floated in a water tank (also called a cultivation bed) filled with a culture solution, and plants held on the panel are grown. This hydroponic cultivation panel mainly uses styrofoam, but styrofoam is likely to be damaged such as cracked or chipped during high-pressure cleaning, and there is a problem with durability. 【0003】 As a solution to the above problems, a hydroponic cultivation panel having a hollow structure in which an upper sheet and a lower sheet, which are molded products of a plastic sheet, are bonded together has been proposed (see, for example, Patent Document 1). However, this hydroponic cultivation panel has a problem that the manufacturing cost becomes high because it is manufactured through processes such as a process of manufacturing the upper sheet and the lower sheet with their respective dedicated molds and a process of bonding the upper sheet and the lower sheet. In addition, the bonding portion between the upper sheet and the lower sheet may peel off, and there is still a problem with durability. 【0004】 In addition, the hydroponic cultivation panel made of the above styrofoam board and the hydroponic cultivation panel having a hollow structure in which the upper sheet and the lower sheet are bonded together have a problem that since the panel itself has a thickness, it is bulky during storage and the storage efficiency is poor, and the scale of the cultivation equipment becomes large. 【0005】 In addition, in the hydroponic cultivation equipment using the above-described hydroponic cultivation panel, since a plurality of hydroponic cultivation panels are simply arranged in a non-connected state in the water tank, when moving and collecting these panels, it is necessary to move each panel, and there is a problem that the workability is poor. 【Prior Art Documents】 【Patent Documents】 【0006】 【Patent Document 1】 Japanese Patent Publication No. 2012-183046 [Overview of the project] [Problems that the invention aims to solve] 【0007】 In light of the above problems, the present invention aims to provide a hydroponic cultivation panel that is highly durable, has low manufacturing costs, and is easy to move when multiple panels are connected together.

[Brief explanation of the drawing] 【0011】 [Figure 1] This is a perspective view of a hydroponic system equipped with a hydroponic panel according to one embodiment of the present invention. [Figure 2] Figure 1 is a perspective view of a hydroponic cultivation panel. [Figure 3] Figure 2 is an exploded view of a hydroponic cultivation panel. [Figure 4] Figure 1 is an explanatory diagram of the connection structure between one hydroponic cultivation panel and other hydroponic cultivation panels. [Figure 5] Figure 1 is a cross-sectional view of the plant-holding section of the hydroponic cultivation panel. [Modes for carrying out the invention] 【0012】 A "hydroponic cultivation panel" and "hydroponic cultivation equipment" according to one embodiment of the present invention will be described with reference to Figures 1 to 5. 【0013】 The hydroponic cultivation system 10 shown in Figure 1 comprises multiple hydroponic cultivation panels 1 and a container 4 holding nutrient solution. In Figure 1, the container 4 is shown interrupted midway, but in reality, the container 4 extends further in the direction of the arrangement of hydroponic cultivation panels 1. Also, although only two hydroponic cultivation panels 1 are shown in the illustration, in reality, two or more are connected and set in the container 4. 【0014】 As shown in Figures 2 and 3, each hydroponic cultivation panel 1 uses two panels 2 and 3 of the same shape and size, stacked vertically as the upper panel 2 and lower panel 3. The upper panel 2 is made of a white synthetic resin, and the lower panel 3 is made of a black synthetic resin. Although the materials are different, they can be manufactured using a single mold. 【0015】 Each panel 2, 3 has a flat plate portion 21, 31, a plurality of plant holding portions 22, 32 protruding downward from the plate portions 21, 31, connecting portions 23, 33 provided only on one end side of the panel 2, 3 and protruding downward from the plate portions 21, 31, ribs 24, 34 protruding upward from the plate portions 21, 31, and grooves 25, 35 provided so as to surround each plant holding portion 22, 32. 【0016】 The plate portions 21, 31, that is, each panel 2, 3, is formed in a rectangular shape when viewed from above. In this example, it is formed in a rectangular shape having a short side and a long side. 【0017】 The connecting portions 23, 33 are provided near one short side of each panel 2, 3 and extend in the short side direction. As shown in FIG. 4, the connecting portions 23, 33 have a hollow tapered shape, and a cross section parallel to the short side of each panel 2, 3 is rectangular, and a cross section parallel to the long side of each panel 2, 3 is an isosceles triangular shape. That is, the connecting portions 23, 33 are recessed downward from the plate portions 21, 31 and become narrower toward the bottom. 【0018】 The ribs 24, 34 are provided near each pair of long sides of each panel 2, 3 and extend in the long side direction. The ribs 24, 34 have a hollow shape that is recessed upward from the plate portions 21, 31. 【0019】 As shown in FIG. 5, the plant holding portions 22, 32 have a cylindrical shape with openings at the upper and lower ends. The plants held in the plant holding portions 22, 32 have roots extending downward and stems extending upward. In this example, the plant holding portions 22, 32 are formed so that the diameter gradually decreases toward the bottom. In addition to this example, a configuration may be adopted in which a bottom wall is provided at the lower end and through holes for passing the roots of the plants are formed in the bottom wall. 【0020】 The grooves 25, 35 are recessed downward from the plate portions 21, 31. Although the grooves 25, 35 and the ribs 24, 34 are not essential components of the present invention, they are effective in improving the rigidity of each panel 2, 3. 【0021】 The upper panel 2 and lower panel 3 are stacked vertically, excluding the connecting parts 23 and 33, in a horizontally inverted state to form the hydroponic cultivation panel 1. Specifically, the plate parts 21 and 31 are stacked vertically, the plant holding parts 22 and 32 are stacked vertically (almost inward and outward), the ribs 24 and 34 are stacked vertically, and the grooves 25 and 35 are stacked vertically. The connecting part 23 of the upper panel 2 is located on one end of the hydroponic cultivation panel 1, and the connecting part 33 of the lower panel 3 is located on the other end of the hydroponic cultivation panel 1. 【0022】 Furthermore, multiple hydroponic cultivation panels 1 are connected by overlapping the connecting parts 23 and 33 vertically. That is, as shown in Figure 4, the connecting part 23 of the upper panel 2 of one hydroponic cultivation panel 1 and the connecting part 33 of the lower panel 3 of another hydroponic cultivation panel 1 adjacent to the first hydroponic cultivation panel 1 are overlapped vertically, thereby connecting one hydroponic cultivation panel 1 to the other hydroponic cultivation panels 1. In this case, it is preferable to have the connecting part 23 on top and the connecting part 33 on the bottom. 【0023】 As shown in Figure 1, the container 4 has horizontal walls 42 extending horizontally on each of a pair of opposing side walls 41. The distance between the pair of side walls 41 is approximately equal to the length of the shorter side of the hydroponic cultivation panel 1. The horizontal walls 42 extend throughout the entire surface of the container 4. In such a container 4, the culture solution is poured in such a way that the liquid level is lower than the horizontal walls 42. 【0024】 Multiple hydroponic panels 1 are set in the container 4 in a connected state as described above. Each hydroponic panel 1 is set in the container 4 by having the vicinity of a pair of long sides (near the back side of the ribs 24 and 34) rest on a pair of horizontal walls 42. When moving or retrieving these multiple hydroponic panels 1, the leading hydroponic panel 1 may be pulled, the last hydroponic panel 1 may be pushed out, or the hydroponic panels 1 in the middle may be pulled or pushed out. 【0025】 The hydroponic cultivation panel 1 of the present invention has sufficient durability to withstand high-pressure washing. Furthermore, since the panels 2 and 3 are simply stacked on top of each other and not glued together, they can be easily assembled and disassembled. Because these two types of panels 2 and 3 can be manufactured with a single mold by simply changing the material, costs can be reduced. In addition, the upper panel 2 is a white color that easily reflects light, which can promote photosynthesis and growth, while the lower panel 3 is a black color that does not easily transmit light, which can suppress the growth of algae in the container 4. 【0026】 Furthermore, by connecting multiple hydroponic cultivation panels 1 using the connecting parts 23 and 33 provided on each panel 2 and 3, multiple hydroponic cultivation panels 1 can be easily moved and collected, thereby improving work efficiency. In addition, by creating a structure in which the connecting parts of the hydroponic cultivation panels 1 are stacked vertically to eliminate gaps, light can be prevented from shining underneath the hydroponic cultivation panels 1 (see Figure 4. The multiple arrows in Figure 4 represent light). 【0027】 Furthermore, the hydroponic cultivation system 10 of the present invention does not float the hydroponic cultivation panel 1 in the culture solution, but rather rests the edge of the hydroponic cultivation panel 1 on the horizontal wall 42 of the container 4. Therefore, there is no need to provide buoyancy to the hydroponic cultivation panel 1. Thus, thin materials can be used for each panel 2, 3, reducing the weight of the panels 2, 3 themselves and the total height when stacked, making it possible to downsize the storage space and the entire system. 【0028】 Furthermore, in the above-described embodiment, the culture solution was stored in the container 4. However, in the present invention, there may be an alternative configuration in which the culture solution is sprayed in a mist-like manner onto the lower surface of the hydroponic cultivation panel 1 set in the container 4. 【0029】 The embodiments described above merely represent typical forms of the present invention, and the present invention is not limited to these embodiments. That is, it can be implemented with various modifications without departing from the core principles of the present invention. As long as such modifications still possess the configuration of the present invention, they are of course included within the scope of the present invention.
