Background Art

[0002] In the event of a disaster, a state where power is not supplied, so-called power outages occur, and situations where disaster victims who have taken refuge in shelters or the like feel inconvenienced are often seen. In such cases, if there is equipment that can easily generate electricity, it can help relieve the inconvenience of the disaster victims.

[0003] The pedestal for mounting a solar power generation panel disclosed in Patent Document 1 was developed for the purpose of ensuring a stable pedestal structure with simple installation work, and has an upper surface on which a 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. It is a tank pedestal integrally formed of a lightweight material such as plastic.

[0004] The solar power generation equipment disclosed in Patent Document 2 was mainly developed for relocation between fields, and comprises solar power generation panels, a frame for holding the solar power generation panels, a pair of foundations arranged symmetrically on both sides along the longitudinal direction of the frame, and a pair of folding frames fixed to the left and right sides symmetrically on the longitudinal direction of the frame, 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 pivotally supported on the frame by a hinge provided on the frame, a long side provided at a predetermined angle of inclination with respect to the base, and a short side 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 with respect to the thickness direction of the frame The settling and pair of foundations consist of a bottom surface that rests on the installation surface, 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 in contact with the long side corresponding to the axis of symmetry and transmit the load acting on the solar power generation panel 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-type mounting frame integrally molded from lightweight materials such as plastic, and therefore has the problem that it cannot be restrained in various ways by various types of three-dimensional structures.

[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 consisting of two commercially available plastic tanks placed side by side and connected by a vertical belt, and then two more tanks connected by a vertical belt placed side by side vertically, with the four tanks connected by a horizontal belt. Similar to Patent Document 1, the fixing method is limited to plastic tanks, and there is a problem that it cannot be restrained in various ways by various three-dimensional structures.

[0009] This invention addresses these problems and provides a solar power generation panel restraint structure that can restrain solar power generation panels in various ways using various types of three-dimensional structures. [Means for solving the problem]

[0010] The invention for solving the above problems is a solar power generation panel restraint structure comprising: a lower structure that can be installed on an installation surface and can be restrained by a three-dimensional structure; an upper structure that is attached to and supported by the lower structure and pivotally mounted to the lower structure so as to be rotatable within a specific angular range with the left-right direction as the axis of rotation, and which can fix a solar power generation panel, wherein the lower structure comprises a pair of axial members having a mountain shape and being installable on the installation surface, a first restraint member provided in the front-rear direction and connected to the axial members, and / or a second restraint member provided in the left-right direction and connected to the axial members, and the first restraint member and / or the second restraint member are restrained by the three-dimensional structure. Preferably, there are multiple first restraining members and second restraining members, and at least two of the first restraining members and at least two of the second restraining members are assembled in a grid pattern and attached to the axial member to form a grid structure, and a part of the grid structure penetrates a hole in the three-dimensional structure so that the grid structure is restrained to the three-dimensional structure.

[0011] This configuration allows for the restraint of solar power generation panels in various ways by various types of three-dimensional structures using a simple structure. Examples of "three-dimensional structures" include, but are not limited to, storage tanks, concrete weights, and sandbags. Furthermore, depending on the situation (for example, if the three-dimensional structure is an empty tank), the solar power generation panel restraint structure can also be used to restrain various types of three-dimensional structures to prevent them from moving. Furthermore, this configuration makes it possible to restrict the movement of solar power generation panels in the left-right and front-back directions.

[0012] Preferably, the first restraining member and / or the second restraining member are provided with fastening portions that restrain the first restraining member and / or the second restraining member to the three-dimensional structure.

[0013] This configuration further increases the binding force.

[0014] Preferably, the axial member has a bottom, and a pile to be installed in the ground can be attached to the bottom.

[0015] This configuration allows for a high level of restraint on the solar panels with a simple structure. Furthermore, by attaching piles, the solar panel restraint structure can be used to restrain the structure itself, for example, if the structure is an empty tank, preventing the structure from moving.

[0016] It is preferable that the shaft-like member and the first restraint member form an A-shaped configuration.

[0017] With this configuration, it becomes easier to change the angle of the solar power generation panel.

[0018] It is preferable that the first restraint member is bent inward In this state .

[0019] With this configuration, the restraining force on the three-dimensional structure can be enhanced.

[0022] It is preferable that the first restraint member and / or the second restraint member is attached to the lower part of the shaft-like member, and the first restraint member and / or the second restraint member has a structure restrained by a sandbag or a base of a sandbag.

[0023] With this configuration, a restraint structure suitable for use in the civil engineering and construction fields can be provided.

[0024] Furthermore, the present invention comprises a lower structure that can be installed on an installation surface and can be restrained by a three-dimensional structure, and an upper structure that is attached to and supported by the lower structure and pivotally mounted to the lower structure so as to be rotatable within a specific angular range with the left-right direction as the axis of rotation, and the upper structure capable of fixing a solar power generation panel, wherein the lower structure has a mountain shape and comprises a pair of axial members that can be installed on the installation surface, a first restraining member provided in the front-rear direction and connected to the axial members and / or a second restraining member provided in the left-right direction and connected to the axial members, and the first restraining member and / or the second restraining member are restrained by the three-dimensional structure. The upper structure is provided in the front-rear direction and includes a pair of first members pivotally attached to a top member provided at the top of the shaft-like member, two pairs of second members pivotally attached to the first members, a pair of third members pivotally attached to the second members and also pivotally attached to the top member, and a rotating member pivotally attached to the pair of third members and capable of fixing a solar power generation panel. The first member and the third member are arranged in parallel and are rotatable within a specific angular range with respect to the top member. Along with this rotation, the first to third members change into a rectangular or parallelogram shape. The upper structure further includes a pair of sliding members having two members with different lengths that are pivotally attached to the third member and extend downward from different positions of the third member and are slidable within a specific position range with respect to the shaft-like member. motion and ru .

[0025] With this configuration, a structure for controlling the elevation angle of the solar power generation panel in a continuously variable manner can be realized, and the solar power generation panel can take a vertical posture, a horizontal posture, or an inclined posture. The purpose of the vertical posture is to save space during storage and transportation. The purpose of the horizontal posture is to install the solar panel in a horizontal posture when, for example, it is impossible to take an elevation angle due to layout at the installation location.

[0026] When attempting to fix the vertical posture, for example, by extending the lower end bending member downward from the second member and fastening it to the rotating member, the vertical posture can be fixed. By releasing the fastening, it can be changed to another posture. When attempting to fix the horizontal posture or the inclined posture, for example, by supporting a fixing member pivotally attached to the rotating member with the third member, the horizontal posture or the inclined posture of the power generation panel can be fixed. By rotating the fixing member, this fixing can be released.

[0027] Ma However, the above solar power generation panel restraint structure Equipped with A three-dimensional structure comprising a storage tank, an installation part for installation on the installation surface, and an annular outer peripheral part extending upward from the outer edge end of the installation part, and the storage tank is fitted in a state of being inserted into the annular outer peripheral part. Preferably .

[0028] According to this configuration, since the storage tank is fitted in a state of being inserted into the annular outer peripheral part in the three-dimensional structure, structural integration of the storage tank, the installation part, and the annular outer peripheral part can be achieved. With this configuration, after installing the structurally integrated three-dimensional structure, lower structure, upper structure, etc. on the installation surface, the installation of the solar power generation panel can be easily completed. Also, it is possible to adopt a structure in which the storage tank does not directly bear external forces such as wind applied to the solar power generation panel, and the load-bearing performance can be improved without giving the storage tank any special strength.

[0029] The storage tank preferably comprises a bottom plate in contact with the installation portion, side plates in contact with the annular outer circumference, and a top plate facing the solar power generation panel. The top plate is provided with an inlet for allowing the stored liquid to flow into the storage tank, and the lower end of the side plate is provided with a discharge port for discharging the stored liquid to the outside of the storage tank.

[0030] With this configuration, an inlet is provided on the top plate for allowing the stored liquid to flow into the storage tank, and an outlet is provided at the lower end of the side plate for discharging the stored liquid to the outside of the storage tank. Therefore, even with the solar power generation panel installed, the stored liquid can be introduced into and discharged from the storage tank. This configuration makes it easy to replace the stored liquid.

[0031] It is preferable that the side panels and the top panel be treated to block light.

[0032] With this configuration, the side and top plates are treated to block light, thereby suppressing photosynthesis by algae present in the stored liquid. This configuration also reduces the frequency of changing the stored liquid.

[0033] Preferably, the annular outer periphery includes a vertical member extending upward from the outer edge of the installation portion and an annular horizontal member connected to the vertical member in a manner that surrounds the vertical member.

[0034] With this configuration, the annular outer periphery has a vertical member extending upward from the outer edge of the installation part and an annular horizontal member that surrounds the vertical member and connects to it. Therefore, it is possible to reduce the weight compared to a cylindrical structure that is generally used.

[0035] Preferably, the installation portion is provided with an insertion hole into which the forks of a forklift can be inserted.

[0036] With this configuration, the installation section is provided with insertion holes into which the forks of a forklift can be inserted, allowing the solar power generation panels to be installed at the installation site using a forklift.

[0037] The annular outer periphery preferably has a grid shape in which the vertical members and the annular horizontal members are arranged vertically and horizontally, and the vertical members are provided with recesses at positions where they intersect with the annular horizontal members, and the annular horizontal members engage with the recesses.

[0038] With this configuration, the recess determines the connection position between the vertical member and the annular horizontal member, and the engagement with the annular horizontal member allows for a stronger connection between the annular horizontal member and the vertical member.

[Modes for carrying out the invention]

[0040] The solar power generation panel restraint structure 1 of Embodiment 1 of the present invention (hereinafter referred to as restraint structure 1) will be described in detail below with reference to Figures 1 to 28.

[0041] The restraint structure 1 comprises a lower structure 3 that can be installed on the installation surface 110 (see Figure 2) and is restrained by a three-dimensional structure 2, and an upper structure 4 that is attached to and supported by the lower structure 3 and pivotally mounted to the lower structure 3 so as to be rotatable about the left-right direction X as the axis of rotation, and is capable of fixing a solar power generation panel 100 (hereinafter referred to as the power generation panel 100). With this configuration, the restraint structure 1 can be restrained by various types of three-dimensional structures 2 in various ways. Furthermore, depending on the situation, the restraint structure 1 can restrain various types of three-dimensional structures 2 in various ways. The details of each configuration will be described below.

[0042] As shown in Figures 1 to 6, 10, 12 to 18, and 20 to 28, in this embodiment, the three-dimensional structure 2 comprises a storage tank 21, an installation portion 22 for installation on the installation surface 110, and an annular outer peripheral portion 23 extending upward from the outer edge of the installation portion 22, and the storage tank 21 is fitted into the annular outer peripheral portion 23 with the storage tank 21 inserted into it.

[0043] Since the three-dimensional structure 2 is fitted with the storage tank 21 inserted into the annular outer circumference 23, at least the storage tank 21, the installation section 22, and the annular outer circumference 23 can be structurally integrated. With this configuration, the installation of the power generation panels 100 can be easily completed by installing the structurally integrated three-dimensional structure 2 etc. on the installation surface 110, and then installing the lower structure 3, upper structure 4, and power generation panels 100. In addition, because of the installation section 22 and the annular outer circumference 23, the storage tank 21 does not have to directly bear external forces such as wind that are applied to the power generation panels 100, and the load-bearing performance can be improved without giving the storage tank 21 any special strength.

[0044] As shown in Figure 2, the three-dimensional structure 2 is installed on the installation surface 110 via the installation part 22. The installation surface 110 is preferably a flat piece of ground. For example, it is preferably a school playground that serves as an evacuation site during disasters.

[0045] The three-dimensional structure 2 has a storage tank 21, an installation section 22, and an annular outer perimeter 23. The installation section 22 is a flat plate structure with a roughly rectangular shape in plan view, with a bottom plate 111 in contact with the installation surface 110 and an upper surface 112 in contact with the storage tank 21. The installation section 22 is provided with insertion holes 22-3 on its side surface 22-2 into which forklift forks (not shown) can be inserted. The forks can be inserted into and removed from the insertion holes 22-3, and are structured to be easily inserted into and removed from the insertion holes 22-3. The installation section 22 and other components can be easily transported to the construction site by using a forklift when loading and unloading from a truck.

[0046] The storage tank 21 holds a storage liquid. The weight effect of the storage liquid makes it possible to make the installation section 22 a gravity-type foundation structure. In this embodiment, the storage tank 21 is located almost entirely within the internal area of ​​the power generation panel 100 in a plan view. The storage tank 21 only needs to have a shape and weight that prevents it from tipping over when subjected to external forces such as wind.

[0047] The storage tank 21 is a roughly rectangular container having a bottom plate 24 (not shown), side plates 25, and a top plate 26, and the storage liquid is stored inside.

[0048] The storage tank 21 is fitted into the annular outer circumference 23 by the side plate 25 coming into contact with the vertical member 23-1. The bottom plate 24 is also in contact with the upper surface 112 of the installation part 22. The storage tank 21 is protected by the installation part 22 and the annular outer circumference 23. External forces such as wind are mainly borne by the installation part 22 via the annular outer circumference 23.

[0049] As shown in Figure 1, the annular outer periphery 23 has a vertical member 23-1 extending upward from the outer edge of the installation portion 22, and an annular horizontal member 23-2 that surrounds the vertical member 23-1 and connects to the vertical member 23-1. Compared to a cylindrical structure that is generally used, it is possible to reduce the weight.

[0050] The annular outer periphery 23 has a so-called grid shape in which vertical members 23-1 and annular horizontal members 23-2 are assembled vertically and horizontally, and is fitted in place with the storage tank 21 inserted, extending upward (away from the installation surface 110) from the outer edge of the installation section 22. The vertical members 23-1 are metal rod-shaped members that have been subjected to surface protection treatment such as zinc plating, and are arranged at predetermined intervals at the outer edge of the installation section 22, extending upward. The annular horizontal members 23-2 are metal rod-shaped members that have been subjected to surface protection treatment such as zinc plating, and are provided in an annular shape surrounding the vertical members 23-1. The vertical members 23-1 have recesses 23-3 at positions where they intersect with the annular horizontal members 23-2 (for example, at perpendicular positions) (see Figure 26). The recess 23-3 is intended to determine the connection position with the annular horizontal member 23-2 and to maintain a stronger connection between the annular horizontal member 23-2 and the vertical member 23-1 through engagement with the annular horizontal member 23-2. The upper end of the vertical member 23-1 is joined to the annular joint 23-4, and is structurally integrated with it.

[0051] The side panels 25 and the top panel 26 are treated to block light. Because the side panels 25 and the top panel 26 are treated to block light, photosynthesis by algae present in the storage liquid can be suppressed. This reduces the frequency of changing the storage liquid.

[0052] Specifically, light-shielding sheets 26A are attached to the outer surfaces of the side plates 25 and the top plate 26 (see Figure 26). Sunlight shining from the outside into the storage tank 21 is blocked by the light-shielding sheets 26A, thereby suppressing photosynthesis of algae present in the stored liquid. The stored liquid is preferably a liquid that can be easily procured at the construction site and is unlikely to pollute the surrounding environment if discharged, such as well water, river water, tap water, or rainwater.

[0053] An inlet 27 for allowing the stored liquid to flow into the storage tank 21 is provided in the center of the top plate 26. The inlet 27 can be sealed with a cap. An outlet 28 for discharging the stored liquid is provided at the lower end of the side plate 25. The outlet 28 can be opened and closed with a cock.

[0054] With the power generation panel 100 installed, the stored liquid can be introduced into and discharged from the storage tank 21. This facilitates the replacement of the stored liquid.

[0055] There is one hanging bracket (not shown) in the center of each side of the tabletop 26, and a total of multiple hanging brackets are attached.

[0056] The housing (not shown) contains a battery for storing the electricity generated by the power generation panel 100, an inverter for converting the electricity stored in the battery into alternating current, and other components, and is supported by a top plate 26.

[0057] Alternatively, instead of the storage tank 21, concrete weights or the like can be inserted into the space defined by the installation section 22 and the annular outer circumference 23.

[0058] As shown in Figures 1 and 2, the lower structure 3 has a V-shape and is made of pipes, comprising a pair of axial members 31 that can be installed on the installation surface 110, a pair of first restraining members 32 provided in the front-rear direction Y and connected to the axial members 31, a pair of second restraining members 33 provided in the left-right direction X and connected to the axial members 31, and a top member 34 provided at the top of the axial members 31. Each of the pair of axial members 31 has a bottom portion 31-1, and a hole 31-2 is provided in the bottom portion 31-1.

[0059] As shown in Figures 1 and 2, the first restraining member 32 is bent inward toward the three-dimensional structure 2 at two points and comprises a pair of inclined plates 32-1 and a flat plate 32-2 extending in the Y direction that connects the inclined plates 32-1. The movement in the left-right direction X is restrained by the annular outer circumference 23 of the three-dimensional structure 2 when the flat plate 32-2 is restrained, thereby increasing the overall restraining force.

[0060] The axial member 31 and the first restraining member 32 form an "A" shape when viewed from the side. This makes the structure compact and makes it easy to change the angle of the power generation panel 100. The axial member 31 has its top bent in a curved shape. The top member 34 consists of a pair of parallel rectangular plates arranged vertically, and is fastened by multiple fastening members in a state where the top is sandwiched at specific intervals. The top member 34 is positioned above the second restraining member 33.

[0061] The first restraining member 32 includes a fastening portion 32-3 that restrains the first restraining member 32 to the three-dimensional structure 2. The fastening portion 32-3 is a fastening member that fastens the flat plate 32-2 of the first restraining member 32 to the annular transverse member 23-2 of the annular outer circumference 23 of the three-dimensional structure 2. The fastening portion 32-3 restrains the first restraining member 32 to the three-dimensional structure 2 with a plurality of U-bolts. The second restraining member 33 includes a fastening portion 33-1 that restrains the second restraining member 33 to the three-dimensional structure 2. The fastening portion 33-1 is a fastening member that fastens both ends of the second restraining member 33 to the annular joint portion 23-4 located at the upper end of the annular outer circumference 23 of the three-dimensional structure 2. The fastening portion 33-1 restrains the second restraining member 33 to the three-dimensional structure 2 with a plurality of metal fittings made from processed steel plates and bolts. In this embodiment, both the first restraining member 32 and the second restraining member 33 are provided, and the restraining effect is enhanced by restraining with both members. However, it is also possible to provide either the first restraining member 32 or the second restraining member 33 and restrain with either one.

[0062] As shown in Figures 5 to 10, the upper structure 4 has a structure that supports a pair of power generation panels 100 and is mounted to the lower structure 3 so as to be rotatable with respect to the left-right direction X as the axis of rotation within a specific angular range (for example, elevation angle 0 to 25°).

[0063] The superstructure 4 is a structure provided in the front-rear direction Y, left-right direction X, and height direction Z, and comprises a pair of long angle frame-shaped first members 41 that are pivotally attached to the top member 34 by shafts 34-4, two pairs of short plate-shaped second members 42 and 43 that are pivotally attached to the first members 41, a third member 44 made of a pair of pipes that are pivotally attached to the second members 42 and 43 and also pivotally attached to the top member 34 by shafts 34-5 and rotate in the R direction (see Figure 10), and an angle frame-shaped rotating member 45 that is pivotally attached to the pair of third members 44 and can rotate in the T direction about specific positions of the third members 44 (both ends in this embodiment) (see Figure 17), and is capable of fixing the power generation panel 100. The rotating member 45 has a grid structure.

[0064] The first member 41 and the third member 44 are arranged parallel to each other and are rotatable in the R direction at an angle within a specific range relative to the top member 34. The first member 41, the second members 42 and 43, and the third member 44 change into a rectangle or parallelogram shape as they rotate in this R direction. The superstructure 4 further includes a pair of sliding members 48, as shown in Figure 10, which are pivotally attached to the third member 44 and extend downward from different positions on the third member 44, respectively, and are slidable within a specific range of positions relative to the opposing members of the axial member 31 in diagonal directions L and N. The lower ends of members 46 and 47 are connected to the axial member 31 by saddle bands 45-1 and 45-2. The pair of sliding members 48 slide along the axial member 31 in the axial direction (L direction and N direction) as the third member 44 rotates.

[0065] This configuration allows for a structure that controls the elevation angle in a stepless variable manner, for example, a stepless variable structure with an elevation angle of 0° to 25° within a specific range. As a result, the power generation panel 100 can assume a horizontal position with the upper structure 4 horizontal (Figures 12 to 16), a vertical position with the upper structure 4 horizontal (Figures 17 to 18), a vertical position with the upper structure 4 tilted (Figures 20 to 22), and a tilted position (Figures 23 to 25). The purpose of the vertical position with the upper structure 4 horizontal is to save space during storage and transportation. The purpose of the horizontal position with the upper structure 4 horizontal is to allow the power generation panel 100 to be installed in a horizontal position when, due to layout constraints at the installation site, it is not possible to adopt a tilted position that utilizes the elevation angle.

[0066] To fix the vertical position of the power generation panel 100, as shown in Figures 17 to 19, a pair of lower end bending members 49 are extended downward from the second members 42 and 43, and the lower end bending members 49 and the rotating member 45 are fastened together with a fastener 49-1 and a hole 49-2 in the rotating member 45 (see Figure 10), thereby fixing the upper structure 4 in a horizontal vertical position.

[0067] When the fastener 49-1 and the hole 49-2 overlap, a lock pin (not shown) is inserted into the rotating member 45 and connected to the fastener 49-1, thereby fixing the vertical position of the power generation panel 100. Although the lock pin is not shown in the drawing, a safety coupler pin with a D-shaped arch is an example. By releasing this fastening, the panel can be changed to another position.

[0068] To fix the power generation panel 100 in a horizontal or inclined position, as shown in Figures 9 and 15, a fixing member 45-3, which is rotatably attached to the rotating member 45, is supported by the third member 44, thereby fixing the power generation panel 100 in a horizontal or inclined position. This fixing can be released by rotating the fixing member 45-3.

[0069] As shown in Figure 28, lifting operations using the crane 130A are also possible. The panels can be lifted using ropes or hooks on the lifting section, which is composed of the top member 34, etc. The design ensures that the lifting section is not hidden whether the power generation panel 100 is in a vertical position or in an inclined position with an elevation angle.

[0070] As shown in Figure 28, the restraint structure 1, the three-dimensional structure 2, and the power generation panel 100 may be transported as a single unit using a crane truck 130 or the like, or they may be transported separately. In the case of transported as a single unit, the remaining loading space is expanded, allowing other materials 140, 150, etc. to be loaded, thus increasing transport efficiency. To improve transport efficiency, the storage tank 21 is kept empty of stored liquid. In this embodiment, a crane truck was used for transport, but a transport vehicle such as a truck may also be used. In this case, the loading and unloading of the three-dimensional structure 2 may be handled using a forklift.

[0071] After being transported to the installation site, the crane 130A attached to the Unic truck 130 is used to unload the restraint structure 1, the three-dimensional structure 2, and the power generation panels 100 to the planned installation site and install them on the installation surface 110.

[0072] When transporting the restraint structure 1, the three-dimensional structure 2, and the power generation panel 100 in separate parts, the parts are assembled after being installed at the planned installation site. Installation is completed by storing the liquid in the storage tank 21 using the inlet 27. If there is a nearby river, river water can be used as the liquid; if there is a well, well water can be used. If it is difficult to procure river water or well water at the planned installation site, the liquid may be stored in the storage tank 21 in advance before transport.

[0073] Dismantling can be done by first draining the liquid from the storage tank 21, and then following the reverse procedure of setup. It is preferable to drain the liquid from the storage tank 21 by connecting a hose to the outlet 28 and discharging it through this hose into a nearby drain.

[0074] The photovoltaic panel restraint structure 201 of Embodiment 2 of the present invention will be described in detail below with reference to Figures 29 to 32. The parts corresponding to Embodiment 1 will be renumbered in the 200s.

[0075] Let's explain using an example where the three-dimensional structure 2 is the concrete weight 202.

[0076] In this embodiment, two second restraint members 233, which are made of pipes and are provided in the left-right direction X, are connected and fixed to the lower part of the shaft-shaped member 231 by fastening members. Also in this embodiment, four first restraint members 232, which are provided in the front-rear direction Y, are connected to the shaft-shaped member 231. Two of the four first restraint members 232-1 have substantially the same configuration as the first restraint member 32 of Embodiment 1 and are directly connected and fixed to the approximate center of the shaft-shaped member 231. Two of the four first restraint members 232-2, which are made of pipes, are connected and fixed to the two second restraint members 233 by fastening members, and as a result, the two first restraint members 232-2 are connected and fixed to the lower part of the shaft-shaped member 231 via the second restraint members 233. The two second restraint members 233 and the two first restraint members 232-2 constitute a lattice-like structural frame. The grid structure is restrained by the concrete weight 202 when the first restraining member 232-2 penetrates the hole in the concrete weight 202. Here, the concrete weight 202 has legs 202-1 at its four corners, and the first restraining member 232-2 penetrates the holes in the legs 202-1. In addition, the first restraining member 232-1 is restrained by abutting against the side surface of the concrete weight 202. Of course, weights made of other materials such as metal, resin, or ceramic may be used instead of the concrete weight 202.

[0077] This configuration allows the solar power generation panel 200 to be constrained by a three-dimensional concrete weight 202, thereby restricting the movement of the solar power generation panel 200 in the left-right direction (X) and the front-back direction (Y). Because a concrete weight 202 is used, it is suitable for use in civil engineering and construction fields.

[0078] The photovoltaic panel restraint structure 301 of Embodiment 3 of the present invention will be described in detail below with reference to Figures 33 to 36.

[0079] Let's explain using an example where three-dimensional structure 2 is a three-dimensional structure 302 composed of sandbags 302-1 as weights and a base 302-2 on which the sandbags 302-1 are stacked.

[0080] In this embodiment, two second restraint members 333, which are made of pipes and are provided in the left-right direction X, are connected and fixed to the lower part of the shaft-shaped member 331 by fastening members. In this embodiment, five first restraint members 332, which are provided in the front-rear direction Y, are also connected to the shaft-shaped member 331. Two of the five first restraint members 332-1 have a configuration substantially similar to the first restraint member 32 of Embodiment 1 and are directly connected and fixed to the approximate center of the shaft-shaped member 331. Three of the five first restraint members 332-2, which are made of pipes, are connected and fixed to the two second restraint members 333 by fastening members, and as a result, the three first restraint members 332-2 are connected and fixed to the lower part of the shaft-shaped member 331 via the second restraint members 333. The two second restraint members 333 and the three first restraint members 332-2 constitute a lattice-like structural frame. The first restraining member 332-2 penetrates the hole in the base 302-2, thereby restraining the grid structure to the three-dimensional structure 302. Here, the base 302-2 has five legs 302-3 at the four corners and in the center, and the first restraining member 332-2 penetrates the holes in the legs 302-3. As the sandbags 302-1 are stacked higher, the first restraining member 332-1 is restrained to the sides of the sandbags 302-1.

[0081] This configuration allows the solar power generation panel 300 to be constrained to the three-dimensional structure 302, thereby restricting the movement of the solar power generation panel 300 in the left-right direction X and the front-back direction Y. Because it uses sandbags 302-1 stacked on the base 302-2, it is suitable for use in civil engineering and construction fields.

[0082] The photovoltaic panel restraint structure 401 of Embodiment 4 of the present invention will be described in detail below with reference to Figures 37 to 40.

[0083] Let's explain using an example where three-dimensional structure 2 is represented by sandbags 402 as weights.

[0084] In this embodiment, two second restraining members 433, which are made of pipes and are provided in the left-right direction X, are connected and fixed to the lower part of the axial member 431 by fastening members. The first restraining member 432 has substantially the same configuration as the first restraining member 32 of Embodiment 1 and is directly connected and fixed to the approximate center of the axial member 431. The second restraining members 433 are restrained by the weight of the sandbags 402. As shown in the figure, if sandbags 402 having a constricted portion in the center are used and the constricted portion of the sandbags 402 engages with the second restraining members 433, the restraint can be made more secure. If the sandbags 402 are stacked high, the first restraining members 432 will be restrained to the sides of the sandbags 402. Instead of the second restraining member 433, which is provided in the left-right direction X and connected and fixed to the lower part of the axial member 431, a first restraining member 432-1 may be provided in the front-rear direction Y and connected and fixed to the lower part of the axial member 431. Alternatively, as in embodiments 2 and 3, the second restraining member 433 and the first restraining member 432-1 may be used to form a lattice-like frame.

[0085] This configuration allows the solar power generation panel 400 to be constrained by the three-dimensional structure, the sandbag 402, thereby restricting the movement of the solar power generation panel 400 in the left-right direction (X) and the front-back direction (Y). Because it uses sandbags 402, it is suitable for use in civil engineering and construction fields.

[0086] As shown in Figure 41, the axial member 3 has a bottom portion 31-1, which is applicable to embodiments 1 to 4. A screw pile 35, which is installed in the ground, can be attached to a hole 31-2 in the bottom portion 31-1. The screw pile 35 and the three-dimensional structure 2 (202, 302, 402) restrain the solar power generation panel 100 (200, 300, 400). This configuration allows for a high restraining force on the solar power generation panel with a simple structure.

[0087] While screw piles 35 are used on soil surfaces, installation on concrete surfaces can be handled by replacing the screw piles 35 with anchor bolts (not shown). Diagrams using anchor bolts are omitted.

[0088] This embodiment is illustrative and can, of course, be modified without departing from the technical spirit of the present invention. [Industrial applicability]

[0089] The solar power generation panel restraint structure according to the present invention has great industrial potential because it can be used in a wide range of applications, such as in places where a power source is temporarily required, for example, evacuation sites during disasters, construction sites, and factories using spot coolers.
