Description

Technical Field

[0001] The present invention relates to a solar power generation panel stand for installing a solar power generation panel.

Background Art

[0002] In the event of a disaster, there is often a situation where power is not supplied, for example, a power outage occurs, and the affected people who have taken refuge in a shelter or the like feel inconvenienced. In such a case, if there is a facility that can easily generate electricity, it can help relieve the inconvenience of the affected people.

[0003] The stand for mounting a solar power generation panel disclosed in Patent Document 1 was developed for the purpose of ensuring a stable stand structure with simple installation work, and is a tank stand integrally formed of a lightweight material such as plastic, having an upper surface on which the solar power generation panel is mounted, and a side surface provided with a first opening (inlet) and a second opening (outlet) that opens at a position lower than the first opening.

[0004] The solar power generation equipment disclosed in Patent Document 2 was mainly developed for relocation between fields, and comprises a solar panel, a frame for holding the solar panel, a pair of foundations arranged symmetrically on the left and right sides of the frame in the longitudinal direction, and a pair of folding frames, arranged symmetrically on the left and right sides of the frame in the longitudinal direction, fixed so as to be able to take a folded position in contact with the frame and an upright position perpendicular to the frame, wherein each of the pair of folding frames has a base that is pivotally supported to the frame by a hinge provided on the frame, a long side that is inclined at a predetermined angle of inclination with respect to the base, and a short side that is perpendicular to the long side and connected to the base, and each of the pair of folding frames, in the folded position, is located within the frame in the thickness direction of the frame The settling and pair of foundations consist of a bottom surface that rests on the ground, a handle having a top surface parallel to the bottom surface, and an even number of tanks having a gap below the handle through which a belt can be inserted, arranged close together with the long side of the pair of folding frames as the axis of symmetry when the pair of folding frames are in the upright position, the even number of tanks are fastened together with a horizontal belt, and each of the even number of tanks is filled with water. The relocating solar power generation equipment for fields further consists of a pair of foundation plates that rest on the top surface of each of the even number of tanks and have hook legs that engage with at least some of the handles of the even number of tanks, and have grooves in the longitudinal center that are aligned with the axis of symmetry and touch the long side, and transmit the load acting on the solar panels and frame to the foundation, and a connecting belt that removably fastens the pair of foundations and the pair of folding frames.

[0005] The aforementioned solar power generation equipment was developed for use between fields, but each component can be moved from one farmland with poor footing to another. After installation, it can achieve structural strength performance exceeding the standards set by the Building Standards Act, and can be removed during the farming season. Therefore, it is considered that it can also be used as equipment to supply electricity in evacuation centers and other locations. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Japanese Patent Publication No. 2004-6566 [Patent Document 2] Japanese Patent Publication No. 2015-144555 [Overview of the project] [Problems that the invention aims to solve]

[0007] The mounting frame for solar power generation panels disclosed in Patent Document 1 is a tank frame integrally molded from lightweight materials such as plastic, making it difficult to ensure durability. For example, the sides and bottom of the tank frame are not protected and are directly subjected to external forces. Therefore, during transportation or installation, accidental collisions with something could cause cracks or chips in the tank.

[0008] The solar power generation equipment disclosed in Patent Document 2 uses many relatively lightweight parts. For example, the foundation has a pair of foundation units. The foundation unit consists of four tanks, each connected by horizontal belts, by placing two commercially available plastic tanks side by side and connecting them with vertical belts, then placing two more tanks connected by vertical belts side by side vertically. Although the weight of each individual part is relatively light, the large number of parts necessitates multiple steps in assembling them to form the foundation, making installation time-consuming. Furthermore, if water is stored in the plastic tanks for a long period, there is a possibility that it may emit an unpleasant odor due to the growth of algae, etc. In this case, it is necessary to drain the water from the plastic tanks, but draining the water requires dismantling the foundation.

[0009] This invention was made in view of these problems and provides a solar power generation panel mounting frame that can be easily set up and taken down, and has excellent load-bearing capacity against impact forces and other factors, as well as durability. [Means for solving the problem]

[0010] The invention for solving the above problems is a solar power generation panel mounting frame comprising a support beam section for supporting solar power generation panels, a support column for detachably fixing the support beam section at its end, a bottomed grid cylinder in a cylindrical shape, a bottom plate, side plates, and a top plate, wherein the grid cylinder is fitted into the container body, and the support columns are arranged opposite each other with the grid cylinder in between, and connected to the side plates via the grid cylinder.

[0011] In this configuration, the container body is fitted into the grid cylinder, and the support columns are positioned opposite each other across the grid cylinder, connecting to the side plates via the grid cylinder at their lower ends. Thus, the container body, grid cylinder, and support columns are structurally integrated. Furthermore, the support columns have a support beam section that detachably attaches to the support beam section that supports the solar power generation panels at their tips. Therefore, after installing the structurally integrated container body and other components on the installation surface, the support beam section is fixed to the support columns, and the solar power generation panels are connected to the support beam section, thus easily completing the installation of the solar power generation panels. In addition, the external forces applied to the solar power generation panels are borne by the support columns via the support beam section, but since the support columns are connected to the side plates via the grid cylinder, these external forces are borne by the container body via the grid cylinder. This allows the external forces to be distributed among multiple components, thereby reducing the member forces generated on the support columns and other components.

[0012] Preferably, the lattice tube has an installation frame that contacts the bottom plate, a plurality of vertical members that extend from the installation frame toward the top plate while in contact with the side plates, and a plurality of horizontal members that are connected to the plurality of vertical members and surround the plurality of vertical members, and the support columns are fixed to the plurality of horizontal members.

[0013] In this configuration, the lattice tube has an installation frame that contacts the bottom plate, multiple vertical members that extend from the installation frame toward the top plate while in contact with the side plates, and multiple horizontal members that connect to and surround the multiple vertical members. The support columns are fixed to the multiple horizontal members, so that each horizontal member distributes and bears the external force. In addition, the fixing length of the support columns can be set to be long, which reduces the member force generated on the support columns.

[0014] Preferably, the support columns are detachably connected and fixed to the horizontal members by U-bolts.

[0015] With this configuration, the support columns are detachably connected and fixed to the horizontal members by U-bolts, making it easy to secure the support columns to the horizontal members.

[0016] Preferably, the container body has an outer shape that is approximately a rectangular parallelepiped.

[0017] With this configuration, the container body has a roughly rectangular shape, making it easy to handle at the installation site. Furthermore, it improves transportation efficiency when transporting the container to the installation site.

[0018] Preferably, the container is characterized by having an inlet on the top plate for allowing liquid to flow into the container body, and an outlet on the lower end of the side plate for discharging liquid to the outside of the container body.

[0019] With this configuration, an inlet for letting liquid into the container body is provided on the top plate, and an outlet for discharging liquid to the outside of the container body is provided on the lower end of the side plate. This makes it easy to let liquid into the container body and to discharge liquid to the outside of the container body even when a solar power generation panel is attached.

[0020] Preferably, the support beam section is characterized by having a connecting section for connecting to other support beam sections.

[0021] With this configuration, each support beam section has a connecting section for connecting to other support beam sections, making it possible to connect multiple solar power generation panel mounting structures in a continuous manner.

[0022] Preferably, the connecting portion is located at the end of the supporting beam portion.

[0023] With this configuration, the connection point is located at the end of the support beam, so multiple solar power generation panel mounting frames can be easily connected in a continuous manner by connecting the ends of the frames via the connection point.

[0024] Another aspect of the invention for solving the above problems is a method of continuously installing solar power generation panel pedestals, comprising the steps of connecting and fixing a lattice cylinder into which a container body is inserted and a support beam portion with a U-bolt, then connecting and fixing a support column and the support beam portion; moving a plurality of lattice cylinders and arranging one support beam portion and the other support beam portion linearly while bringing one connecting portion and the other connecting portion close to each other; connecting the one connecting portion and the other connecting portion to make the solar power generation panel pedestals continuous; and filling each container body with liquid.

[0025] According to this configuration, a plurality of solar power generation panel pedestals can be installed easily and in a short period of time.

Modes for Carrying Out the Invention

[0027] Hereinafter, Embodiment 1 of the solar power generation panel pedestal 1 (hereinafter referred to as pedestal 1) of the present invention will be described in detail with reference to FIGS. 1 to 4.

[0028] As shown in FIGS. 1 and 2, the solar power generation panel 100 (hereinafter referred to as power generation panel 100) is installed on the installation surface 110 via the pedestal Ⅰ. The installation surface 110 is preferably a flat ground. For example, it is preferably a school ground that serves as an evacuation place during disasters.

[0029] The container body 20 can store water. The weight effect of the water stored in the container body 20 makes it possible to make the mounting frame 1 a gravity-type foundation structure. In this embodiment, the container body 20 is installed in the internal area of ​​the power generation panel 100 in a plan view, but it is not limited to this. The container body 20 only needs to have a shape and weight that prevents it from tipping over when subjected to external forces such as wind.

[0030] The frame 1 comprises a support beam section 10, a container body 20, a grid cylinder 30, and support columns 40. The support beam section 10 directly supports the power generation panel 100 with two support beams 11. The material for the support beams 11 is preferably lightweight, strong, and easy to process. In this embodiment 1, lip channel steel as specified in JIS G 3350 is used as an example, but it is not limited to this.

[0031] The lattice tube 30 has an installation frame 38 that contacts the bottom plate 21 of the container body 20, a plurality of vertical members 31 that extend upward DU (from the bottom plate 21 toward the top plate 23) from the installation frame 38 while in contact with the side plates 22 of the container body 20, and a plurality of horizontal members 32 that are connected to the plurality of vertical members 31 and surround the plurality of vertical members 31. The vertical members 31 and horizontal members 32 are assembled vertically and horizontally and cooperate to form a so-called lattice shape.

[0032] The vertical members 31 are galvanized metal rod-shaped members arranged at predetermined intervals. They extend upward DU from the outer edge of the mounting frame 38, while in contact with the side plate 22.

[0033] The horizontal member 32 is a galvanized metal annular rod member, and is provided in an annular shape surrounding the outer circumference of the vertical member 31. The vertical member 31 has a recess 31a at the position where it connects to the horizontal member 32. By providing the recess 31a, the connection position with the horizontal member 32 can be uniquely determined, and the connection between the vertical member 31 and the horizontal member 32 can be made stronger.

[0034] The mounting base 38 has a flat plate structure that is roughly rectangular in plan view, with its lower end surface 38a in contact with the mounting surface 110 and its upper end surface 38b in contact with the bottom plate 21 of the container body 20. In addition, insertion holes 39a are provided on the side circumferential surface 39 into which forklift forks can be inserted. This allows the grid cylinder 30 to be easily transported to the construction site by using a forklift when loading and unloading onto a truck.

[0035] The container body 20 is a roughly rectangular container having a bottom plate 21, side plates 22, and a top plate 23, and is designed to store water inside. The side plates 22 and the top plate 23 are treated to block light. Specifically, a light-blocking sheet 26 is attached to the outer surface of the side plates 22 and the top plate 23. Sunlight shining from the outside into the container body 20 is blocked by the light-blocking sheet 26, so that photosynthesis by algae living in the stored water can be suppressed. The stored water is preferably a liquid that can be easily procured at the construction site and has a low possibility of polluting the surrounding environment when discharged, such as well water, river water, or tap water.

[0036] The bottom plate 21 is in contact with the upper end surface 38b of the mounting frame 38. The side plates 22 are in contact with the vertical members 31, so that the container body 20 is fitted into the grid cylinder 30. In addition, the top plate 23 is in contact with the restraining member 35 that spans across the opposing vertical members 31 (see Figure 5). As a result, the upward movement of the container body 20 to the DU is restrained.

[0037] An inlet 24 for allowing stored water to flow into the container body 20 is provided in the center of the top plate 23. The inlet 24 can be sealed with a cap (see Figure 5). In addition, an outlet 25 for discharging stored water is provided at the lower end of the side plate 22. The outlet 25 can be opened and closed with a cock.

[0038] The support column 40 is composed of a pair of first support columns 41, 41 and a pair of second support columns 42, 42. The first support column 41 is a longer member than the second support column 42. The first support column 41 and the second support column 42 are arranged opposite each other, with the container body 20 in between.

[0039] The support beam 11 is spanned across the first and second support columns 41 and 42, which are arranged in a row. This provides a predetermined inclination in the direction in which the support beam 11 extends. The support beam 11 and the first support column 41, and the support beam 11 and the second support column 42 are detachably connected by bolts (see Figure 4).

[0040] The four horizontal members 32 located in the middle of the side plate 22 and the first support column 41 are detachably connected by U-bolts 45 (see Figure 3). Similarly, the four horizontal members 32 located in the middle of the side plate 22 and the second support column 42 are detachably connected by U-bolts 45. As a result, the first support column 41 and the second support column 42 are elastically supported by the side plate 22 of the container body 20 via the horizontal members 32 located in the middle of the side plate 22 and the vertical members 31 connected to the horizontal members 32.

[0041] The first support column 41 and the second support column 42 are connected and fixed to each of the four horizontal members 32 arranged in the vertical direction, so that the member forces generated by the first support column 41 and the second support column 42 do not concentrate at a specific location. Furthermore, even if an impact force acts on the first support column 41 and the second support column 42 due to a gust of wind or the like, the impact force is mitigated because the first support column 41 and the second support column 42 are elastically supported by the container body 20. The material for the support columns is preferably lightweight, strong, and easy to process. In this embodiment 1, lip channel steel as specified in JIS G 3350 is given as an example, but it is not limited to this.

[0042] As Embodiment 2 of the present invention, another embodiment of the solar panel power generation mounting frame 201 (hereinafter referred to as mounting frame 201) will be described in detail. Since the first embodiment and the second embodiment have many similarities, the differences from the first embodiment will be mainly explained. Components similar to those in the first embodiment will be denoted by the same reference numerals, while components that differ will be denoted by reference numerals in the 200s.

[0043] Embodiment 2 has a structure in which the two support beams 211 of the two support frames 201 can be integrated by connecting them at their ends. Note that Figure 5 does not show the entire support frame, but only a part of it.

[0044] The support column 40 is composed of a pair of first support columns 41, 41 and a pair of second support columns 42, 42. The first support column 41 is longer than the second support column 42. The pair of first support columns 41, 41 and the pair of second support columns 42, 42 are arranged in a row along the side plate 22. The first support columns 41 and the second support columns 42 are also arranged opposite each other, with the container body 20 in between.

[0045] The support beam section 210 directly supports the power generation panel 100 by two support beams 211. The support beams 211 are detachably connected to the support column 240.

[0046] The support beam 211 spans across a pair of first columns 41, 41 and a pair of second columns 42, 42, which are positioned opposite each other with the container body 20 in between. This provides a predetermined inclination in a direction perpendicular to the direction in which the support beam 211 extends. The support beam 211 and the first columns 41, and the support beam 11 and the second columns 42 are detachably connected by bolts.

[0047] The ends of the support beams 211 are provided with connection holes 250 (connection parts) for inserting bolts. One support beam 211 and the other support beam 211 are arranged in a straight line. Furthermore, one support beam 211 and the other support beam 211 are connected by connecting plates 251 across their respective ends and bolted together using the connection holes 250. As a result, one support beam 211 and the other support beam 211 are structurally integrated.

[0048] The connection holes 250 may be provided only at the ends where connections are planned, but it is preferable to provide them at both ends. This eliminates the need to specify the arrangement of each frame 201 when connecting multiple frames 201.

[0049] This section explains the procedure for connecting and installing multiple mounting frames.

[0050] The grid cylinder 30, into which the container body 20 is fitted, is placed on the installation surface 110. At this time, the container body 20 is not filled with stored water.

[0051] U-bolts 45 are used to connect the four horizontal members 32 located in the middle section with the pair of first support columns 41, 41 and the pair of second support columns 42, 42. At this time, the pair of first support columns 41, 41 and the pair of second support columns 42, 42 are arranged as described above.

[0052] The support beams 211 are connected and fixed to the first columns 41, 41 and the second columns 42, 42 using bolts. The lattice tube 30 is moved to position one support beam 211 and the other support beam 211 in a straight line, bringing the connection holes 250 of one support beam and the other connection hole 250 close together, and the support beams 211 and the other support beam 211 are connected using the connection plate 251.

[0053] After the stored water is poured into each of the container bodies 20, the power generation panels 100 are installed.

[0054] This embodiment is illustrative and can be modified without departing from the technical spirit of the present invention. For example, in Embodiment 1, the direction in which the support beam extends is the direction in which the incline is provided, but it may also be attached in a direction perpendicular to the incline. Also, in Embodiment 2, two frames are connected in a continuous manner, but three or more frames may be connected and made continuous. [Industrial applicability]

[0055] The mounting structure according to the present invention allows for easy installation of power generation panels in evacuation areas during disasters, construction sites, and other locations, and is also easy to remove. Because it can quickly and easily supply electricity to the necessary locations, it has great industrial potential. [Explanation of Symbols]
