Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above-described conventional solar panel installation device, about 10 to 15 years after the solar panel is installed on a base such as the rooftop or roof of a building, there are times when, for example, waterproofing work must be performed as maintenance of the rooftop or roof. As the waterproofing work, for example, a waterproof sheet or the like is pasted on the base surface. Conventionally, in this case, the solar panel mounting frame to which the solar panel is attached must be removed from the solar panel support to perform the waterproofing work. In particular, when many solar panels are installed, the removal process is time-consuming and incurs extra costs. Furthermore, the need to temporarily store the numerous removed solar panels during maintenance presents a problem in terms of storage space.

[0005] Therefore, the objective of the present invention is to resolve the above-mentioned problems and to enable repair work, such as waterproofing, to be carried out on rooftops and other installation areas of solar panels with simple effort and without hindering the storage of a large number of solar panels. [Means for solving the problem]

[0006] The first characteristic configuration of the present invention is that a solar panel support is provided, which includes a pair of solar panel mounting frames for attaching solar panels, a base-side fixing part at the lower end that can be attached to a base, and a mounting frame fixing part at the upper end that can be attached to one end of each of the pair of solar panel mounting frames, a pivot mechanism is provided at the mounting frame fixing part that pivotally supports each of the pair of solar panel mounting frames so that the solar panels can swing up and down, and their other ends can move closer to and further apart from each other, and an upright posture holding device is provided that allows each of the pair of solar panel mounting frames to be erected in order to swing the solar panels upward, and to be held in a position where their other ends are close to each other.

[0007] According to the first characteristic configuration of the present invention, the solar panel mounting frame for attaching the solar panel is attached to the mounting frame fixing part of the solar panel support at one end of each pair, and a pivot mechanism is provided at the mounting frame fixing part that pivotally supports each of the pair of solar panel mounting frames so that the solar panel can swing up and down, and the other ends of the frames can move closer to and further apart from each other. A standing posture holding device is provided that allows each of the pair of solar panel mounting frames to be erected in order to swing the solar panel upward, and to be held in a position where the other ends of the frames are close together. As a result, when performing maintenance on rooftops or roofs, such as waterproofing work, the pair of solar panels can be swung upward by the pivot mechanism provided at the mounting frame fixing part, thereby exposing a large portion of the substrate on the rooftop or roof where the solar panel was installed, making it easy to perform maintenance such as waterproofing work with less effort. Furthermore, by providing an upright posture holding device that allows the pair of solar panels, which are swung upward, to be held in a position where their other ends are close together by erecting the solar panel mounting frames for each panel, it becomes possible to store a large number of solar panels without difficulty and to perform maintenance work.

[0008] A second characteristic feature of the present invention is that the upright posture holding device is configured to connect the other ends of a pair of upright solar panel mounting frames, thereby preventing the solar panel mounting frames from swinging up and down.

[0009] According to the second characteristic configuration of the present invention, by simply connecting the other ends of a pair of solar panel mounting frames with an upright posture holding device, their vertical swinging can be easily prevented, thereby improving work efficiency.

[0010] A third characteristic feature of the present invention is that a stopper device is provided on the mounting frame fixing portion which prevents the other end of the solar panel mounting frame from swinging upward and falling to the opposite side when the solar panel is in an upright position by contacting one end of the solar panel mounting frame.

[0011] According to the third characteristic configuration of the present invention, the stopper device makes it easier to stabilize the upright position of the solar panel mounting frame so that it does not fall to the opposite side, thereby improving the safety of maintenance work.

[0012] A fourth characteristic feature of the present invention is that, in the solar panel mounting frame, support legs that can be placed on the base are attached to the other end.

[0013] According to the fourth feature configuration of the present invention, the support legs attached to the solar panel mounting frame allow the solar panel to be easily and stably installed in a position that receives sunlight when installed on the substrate. Furthermore, when the solar panel swings upward, it rises together with the other end of the solar panel mounting frame, exposing a larger portion of the substrate and making maintenance work easier.

[0014] A fifth characteristic feature of the present invention is that the support leg is capable of having a weight installed that presses against the substrate while it is placed on the substrate.

[0015] According to the fifth characteristic configuration of the present invention, by simply adding a weight, a solar panel in a light-receiving position that receives sunlight from above while its support legs are placed on a base can be stabilized even when strong winds are acting on it. Therefore, by adding a separate weight, the solar panel mounting frame and support legs can be made lighter while still maintaining stability. This allows for easy vertical movement of the solar panel, reducing the effort required for maintenance.

[0016] A sixth characteristic feature of the present invention is that, while the other ends of the solar panel mounting frame are swung downward to bring them close to the base, a locking device is provided that prevents the solar panel from swinging upward, and this locking device is provided in a lockable and unlockable manner between the solar panel support and the solar panel mounting frame, or between adjacent solar panel mounting frames.

[0017] According to the sixth feature configuration of the present invention, by providing a locking device that prevents the solar panel from swinging upward while each of the other ends of the solar panel mounting frame is swung downward to bring it close to the substrate, the solar panel can be easily installed in a stable position to receive sunlight. Furthermore, by unlocking the locking device, when the solar panel swings upward, it rises together with the other ends of the solar panel mounting frame, exposing a larger portion of the substrate and making maintenance work easier. Furthermore, a locking device provided between the solar panel support and the solar panel mounting frame, or between adjacent solar panel mounting frames, mechanically prevents the solar panel support from swinging up and down, thereby enabling stable installation of the solar panel.

[0018] A seventh characteristic feature of the present invention is that, while the other ends of the solar panel mounting frame are swung downward to bring them close to the base, a locking device that prevents the solar panel from swinging upward is provided on the pivot mechanism, and this locking device can be released.

[0019] According to the seventh characteristic configuration of the present invention, when installing a solar panel on a substrate, the other ends of the solar panel mounting frame can be lowered and swung to bring them closer to the substrate, allowing for easy and stable installation in a position that receives sunlight. Furthermore, when the locking device is released and the solar panel swings upward, the other ends of the solar panel mounting frame rise together, exposing a larger portion of the substrate and making maintenance work easier. Furthermore, by providing a locking device that prevents the solar panel from swinging upward on the pivot mechanism in a way that allows it to be unlocked, the locking device can be made more compact.

[0020] The eighth characteristic feature of the present invention is the provision of a solar panel auxiliary support device, which has a mounting frame attachment / detachment fixing part at its upper end that allows it to be detachably attached to the other end of the solar panel mounting frame, and a base-side fixing part at its lower end that allows it to be attached to a base.

[0021] According to the eighth characteristic configuration of the present invention, in order to swing the solar panel upward, when raising the other end side portion of the solar panel mounting frame, the other end side portion of the solar panel mounting frame can be detached from the mounting frame detachable fixing portion of the solar panel auxiliary support tool with the base side fixing portion fixed to the base. Also, both the one end side and the other end side of the solar panel can be surely and stably fixed to the base against the action of external forces in the vertical and horizontal directions due to strong winds and seismic vibrations.

[0022] The ninth characteristic configuration of the present invention is that the mounting frame detachable fixing portion is provided with an operating mechanism that enables attachment and detachment operations to the solar panel mounting frame from above in a state where the solar panel is installed along the base.

[0023] According to the ninth characteristic configuration of the present invention, from a state where a large number of solar panels are installed along the base, since the other end side portion of the solar panel mounting frame can be attached and detached to the solar panel mounting frame from above, the fixing release operation becomes easy for releasing the fixing from the solar panel auxiliary support tool and swinging it upward.

[0024] The tenth characteristic configuration of the present invention is that the mounting frame detachable fixing portion is configured to be attachable such that another pair of the solar panel mounting frames adjacent to the pair of solar panel mounting frames are arranged side by side along the surface of the solar panel.

[0025] According to the tenth characteristic configuration of the present invention, two pairs of solar panel mounting frames adjacent to each other can be installed on one solar panel auxiliary support tool, improving the installation efficiency for the solar panel.

[0026] The characteristic configuration of the method for installing the solar panel in the eleventh aspect of the present invention is that when installing the solar panel installation device, an output cable device spanning between another pair of the solar panel mounting frames adjacent to the pair of solar panel mounting frames is arranged to come to one end side of each of the solar panel mounting frames, and the solar panel is attached to the solar panel mounting frame.

[0027] According to the 11th characteristic configuration of the present invention, when the solar panels are swung up and down, the output cable device that spans between the pair of solar panel mounting frames and another adjacent pair of solar panel mounting frames is located near the pivot mechanism, so that the cables are not pulled and the solar panels can be individually swung up and down, preventing electrical wiring problems during maintenance.

[Modes for carrying out the invention]

[0029] Embodiments of the present invention will be described below with reference to the drawings. As shown in Figure 1, the solar panel 3 is fixed to a building (an example of a base 2) such as a concrete floor on a roof or a balcony using the solar panel installation device 1 of the present invention.

[0030] As shown in Figures 1 and 2, the solar panel installation device 1 includes a solar panel mounting frame 4 for mounting the solar panel 3, a solar panel support 7 with a base-side fixing part 5 at its lower end that can be attached to a base 2, and a mounting frame fixing part 6 at its upper end that can be attached to one end of the solar panel mounting frame 4, and a support leg 8 that can be placed on the base 2 is attached to the other end of the solar panel mounting frame 4.

[0031] As shown in Figures 3 and 4, the solar panel support 7 is divided into upper and lower sections: a base-side support member 9 with a base-side fixing portion 5, and an other-object support member 10 with a mounting frame fixing portion 6. The upper end of the base-side support member 9 and the lower end of the other-object support member 10 are provided with connecting portions 13 that can be connected to each other by connecting bolts 11 and nuts 12.

[0032] The base-side fixing portion 5 of the base-side support member 9 has an anchor bolt insertion hole 15 formed so that it can be fixed to the base 2 by an anchor bolt 14, and the connecting portion 13 has a first elongated hole 16 for inserting a connecting bolt 11. A second insertion slot 17 for the connecting bolt 11 is formed in the connecting portion 13 of the object support member 10, and the first insertion slot 16 and the second insertion slot 17 are formed such that the longitudinal directions of each slot intersect each other in the lateral direction. Therefore, the other object support member 10 is configured to be able to adjust its relative position to the base support member 9 in a two-dimensional lateral direction, and to rotate around the vertical axis in a twisting direction to fix its relative position and connect to it.

[0033] As shown in Figures 3 to 5, the mounting frame fixing portion 6 of the other object support member 10 is provided with a pair of pivot mechanisms 18 that pivotally support the solar panel mounting frame 4 so that each of the multiple solar panels 3 can swing up and down. In other words, each pivot mechanism 18 has bolt insertion holes 20 formed in each of the two side walls 19 that stand opposite each other, and bolts 21 and nuts 22 are attached to these opposing pairs of bolt insertion holes 20. A metal cylindrical sheath tube 23 is loosely fitted around the bolt 21 so as to be rotatable around its coaxial axis, and a pivot shaft 24 is formed on the sheath tube 23 so as to pivot the solar panel mounting frame 4 so as to be able to swing up and down.

[0034] Furthermore, a stopper device 25 is formed by ribs attached to each of the side walls 19 to prevent the other end of the solar panel mounting frame 4 from swinging upward and tipping over to the opposite side when the solar panel 3 is in an upright position, by contacting one end of the solar panel mounting frame 4 with it. As shown in Figures 2 and 6, a standing position holding device 26 is detachably provided to allow the other end of a pair of solar panel mounting frames 4 attached to the other object support member 10 to be swung upward so that the solar panel 3 is in an upright position, and to maintain that upright position. Furthermore, the upright posture holding device 26 is provided with a pair of wing screws 27, and by tightening and rotating the wing screws 27, the pair of solar panel mounting frames 4 are clamped and their upright postures are maintained.

[0035] As shown in Figures 1, 2, 5, and 7, the solar panel 3 is pivotally supported by a pivot mechanism 18 so that each of the pair of solar panel mounting frames 4 can swing up and down, and their other ends can move closer to and further apart from each other. In addition, another pair of solar panel mounting frames 4, different from the pair of solar panel mounting frames 4, can be mounted in parallel along the surface of the solar panel 3. In total, one solar panel support 7 is configured to be able to mount four sets of solar panel mounting frames 4 so that they can swing up and down.

[0036] As shown in Figure 7, the solar panel mounting frame 4 is formed by assembling arm members 4A and cross members 4B, each made of metal angle, in a grid pattern and connecting them with bolts. The solar panel 3 is placed on a pair of cross members 4B, and panel fastening brackets 28 are detachably attached to the frame so that the edges of the solar panel 3 can be clamped and fixed in place.

[0037] Furthermore, instead of using the panel fastening brackets 28 to secure the solar panel 3 to the solar panel mounting frame 4, the solar panel 3 may be directly fixed to the solar panel mounting frame 4 via bolts.

[0038] As shown in Figure 1, the left and right solar panel mounting frames 4 are installed with a gentle slope that becomes lower towards the left and right sides, so that one end on the pivot side is slightly higher than the other end, and the pivot sides are installed along the north-south direction (SN in the figure), so that each of the left and right solar panels 3 can receive sunlight equally throughout the day.

[0039] In the installation of the solar panel 3, as shown in Figures 1, 2, and 7, the solar panel mounting frame 4 is pivotally fixed to the solar panel support 7 at one end, as described above, while the other end is positioned to receive sunlight from above with the support legs 8 resting on the base 2. To stabilize it in this light-receiving position, a weight (not shown) that normally presses the support legs 8 against the base 2 is made detachable.

[0040] Furthermore, the aforementioned weight is not necessarily required unless the solar panel 3, when attached to the solar panel mounting frame 4, is heavy enough to cause it to float due to strong winds or other factors.

[0041] However, the other end of the solar panel mounting frame 4 to which the support legs 8 are attached may be the other end of the arm member 4A, or the left and right intermediate parts of the crossbar member 4B located on the other end, from both ends to the center. In other words, the position where the support legs 8 are attached is collectively referred to as the other end of the solar panel mounting frame 4.

[0042] Furthermore, when installing the solar panel mounting device, the output cable device that spans between one pair of solar panel mounting frames 4 and another adjacent pair of solar panel mounting frames 4 is positioned so that it is located at one end of each solar panel mounting frame 4. In other words, when the solar panels 3 are swung up and down by attaching one end of each solar panel mounting frame 4 to the pivot mechanism 18 of the mounting frame fixing part 6, even if a pair of solar panels 3 and adjacent solar panels 3 are connected to each other by output cable devices such as connectors and cables that electrically connect them, the cables will not be pulled, and the solar panels 3 can be individually swung up and down, preventing electrical wiring problems during maintenance.

[0043] [Another embodiment] Other embodiments are described below. In addition, in the following other embodiments, the same reference numerals are used for components similar to those in the above embodiment. <1> In order to stabilize the solar panel 3 in a light-receiving position, a locking device (not shown) that prevents the solar panel 3 from swinging upward while the support legs 8 are placed on the base 2 may be provided in a lockable and unlockable manner between the solar panel support 7 and the solar panel mounting frame 4, or between multiple adjacent solar panel mounting frames 4. <2> In order to stabilize the solar panel 3 in a light-receiving position, a locking device (not shown) that prevents the solar panel 3 from swinging upward while the support legs 8 are placed on the base 2 may be provided on the pivot mechanism 18 in a way that allows it to be unlocked. <3> As shown in Figures 1, 2, and 7, the support legs 8 are provided approximately in the center of the longitudinal direction of the crossbar member 4B in the solar panel mounting frame 4. However, they may also be provided in locations other than the center, or in pairs at each end, or at the other end of the arm member 4A. The location where the support legs 8 are provided, including these locations, will be referred to as the other end side of the solar panel mounting frame 4. Similarly, in the solar panel support 7, the location where the solar panel mounting frame 4 is attached to the mounting frame fixing part 6 may also be the middle or both ends of the crossbar member 4B attached to the mounting frame fixing part 6, in addition to one end of the arm member 4A in the solar panel mounting frame 4. This will be referred to as attaching the one end side of the solar panel mounting frame 4 to the mounting frame fixing part 6. <4> In the solar panel mounting frame 4, instead of providing support legs 8 on the other end, a solar panel auxiliary support 30 may be provided, as shown in Figures 8 and 9, which has a mounting frame attachment / detachment fixing part 30B at its upper end that allows the other end to be attached and detached, and a base-side fixing part 30A at its lower end that can be attached to a base. In order to swing the solar panel 3 upward, when raising the other end of the solar panel mounting frame 4, the other end of the solar panel mounting frame 4 may be detached from the mounting frame attachment / detachment fixing part 30A of the solar panel auxiliary support 30, which has the base-side fixing part 30A fixed to the base. Furthermore, the base-side fixing part 30A and the mounting frame attachment / detachment fixing part 30B are formed from separate metal fittings and are configured to be connectable to each other with bolts 31A and nuts 31B. Furthermore, in Figures 8 and 9, the other end of each of the two adjacent solar panel mounting frames 4 can be attached to and secured to a single solar panel auxiliary support 30. In this case, one end and the other end of the solar panel 3 can be securely and stably fixed to the substrate even when subjected to vertical and horizontal external forces caused by strong winds or seismic activity. <5> When providing the solar panel auxiliary support 30, as shown in Figures 8 and 9, the connection structure of the solar panel mounting frame 4 to the mounting frame attachment / detachment fixing part 30B should be such that an operating mechanism 32 can be attached and detached from above when the solar panel 3 is installed roughly along the base 2, and the other end of the solar panel mounting frame 4 can be released from the solar panel auxiliary support 30 and swung upward, from a state in which a number of solar panels 3 are arranged and fixed in a roughly planar manner on the base 2, and the release operation should be made easy. The operating mechanism 32 described above is constructed by providing an elongated bolt insertion hole 32A at the other end of the arm member 4A, and a bolt insertion hole 32B that is longer in a direction different from the bolt insertion hole 32A in the mounting frame attachment / detachment fixing part 30B, and providing a bolt 32C that can be inserted into these bolt insertion holes 32A and bolt insertion hole 32B, and a nut 32D that connects to the bolt 32C. Furthermore, the mounting frame attachment / detachment fixing part 30B is provided with large elongated holes 32E in the bolt insertion holes 32A and 32B, for inserting the bolt 32C from below, bolt head and all (Figure 9). <6> The stopper device 25 is made up of ribs, but it may be made up of other structures. <7> The upright posture holding device 26 is not limited to the one shown in Figure 6, but may also be made of a flexible material other than metal, or a chain-like object that can connect the other ends of a pair of erected solar panel mounting frames 4, in which case it may be permanently attached to one side of the pair of solar panel mounting frames 4. <8> The mounting position of the upright posture holding device 26 is not limited to the height shown in Figure 2, but can be mounted at any height that facilitates attachment and detachment. <9> The solar panel support 7 is composed of separate components, the base support member 9 and the other object support member 10, but it may also be formed as a single unit. <10> In the embodiment shown, the pair of pivot mechanisms 18 provided on the solar panel support 7 have pivot shafts 24 of the same height, but they may be of different heights.

[0044] As mentioned above, reference numerals have been used to facilitate comparison with the drawings, but this does not mean that the present invention is limited to the configuration shown in the attached drawings. Furthermore, it goes without saying that the present invention can be implemented in various forms without departing from the spirit of the invention. [Explanation of Symbols]
