Description

Technical Field

[0001] This invention relates to the field of solar power generation technology, and to a portable, mobile solar power generation device. Background Technology

[0002] To enable disaster victims who seek refuge in shelters and other locations to access electricity as quickly as possible, various portable solar power generation devices have been developed.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 9-199748 [Patent Document 2] Japanese Patent Application Publication No. 2016-15836 The portable solar power generation device of Patent Document 1 allows for the tilting arrangement of several permanent solar cell modules on the casing during power generation. Furthermore, the casing includes: a storage chamber for accommodating several additional solar cell modules during transport; a battery for charging with electricity generated by the permanent solar cell modules; and a control chamber equipped with a connection panel, control panel, distribution panel, measuring instruments, etc., for removing the permanent solar cell modules and / or the battery for use as an external power source.

[0004] The portable solar power generation device of Patent Document 2 includes a portable main body, a top solar panel mounted on the top surface of the main body, and side solar panels connected to the sides of the main body in a foldable manner. After the main body is installed, the side solar panels can be unfolded to generate electricity through the top solar panel and the side solar panels.

[0005] The portable solar power generation device proposed in Patent Document 1 is based on the premise that the batteries in the battery room are placed directly on the ground while connected to each other. Because it is a flat surface, a large area is required, making it difficult to transport several portable solar power generation devices efficiently. In addition, during on-site installation, components such as solar panels need to be installed separately.

[0006] The mobile solar power generation device proposed in Patent Document 2 requires additional assembly of support components when the side solar panels are deployed, making it difficult to improve the efficiency of the installation process. Furthermore, when installing batteries, they need to be installed and removed during movement. Additionally, no measures have been taken to create a suitable environment for battery storage. Summary of the Invention

[0007] This invention addresses the aforementioned problems by providing a mobile solar power generation device with excellent transmission efficiency and simple setup and dismantling operations.

[0008] To address the aforementioned issues, the present invention provides a portable solar power generation device comprising: a solar power generation panel, a device storage section for storing an energy storage device, and a pair of legs connected in a rotatable state to a frame portion constituting the skeleton of the device storage section via rotating ends. The device storage section includes a first panel defining a first wall surface, a second panel defining an intersecting surface with the first wall surface, i.e., a second wall surface, and a ceiling panel. The solar power generation panel includes: a panel body whose base end is rotatably connected to the frame portion, and a posture maintenance section for maintaining the posture of the panel body. The front ends of each pair of legs can be in an open-leg posture on the mounting surface in an opposing state, spaced apart from the rotating ends, and can also be in a closed-leg posture. The distance between the front ends is shorter than when the legs are in an open-leg posture.

[0009] Based on the above structure, the portable solar power generation device has a device storage section that can accommodate energy storage devices. Devices requiring pre-generation, such as batteries and inverters, can be stored in this section, allowing for direct power supply after installation. Furthermore, the solar panel has a panel body with its base rotatably connected to the frame, and a posture holding section to maintain the panel body's posture. Therefore, the planar area occupied by the solar panel can be reduced during transport, and increased during power generation, allowing for a posture suitable for the current situation. Additionally, the front ends of the legs can be in an open-leg posture, facing each other and grounded to the installation surface, while simultaneously in a closed-leg posture with a shorter distance between the front ends compared to the open-leg posture. This achieves device stability and improves transport efficiency.

[0010] Ideally, the posture maintaining part has a first arm rotatably connected to the middle part of the frame, a second arm rotatably connected to the middle part of the panel body, and a positioning pin. The first arm and the second arm are slidably connected along the axial direction, and the positioning pin is inserted into the overlap of the first hole provided in the first arm and the second hole provided in the second arm.

[0011] Based on this structure, the posture maintaining part has a first arm rotatably connected to the middle part of the frame and a second arm rotatably connected to the middle part of the panel body. The first arm and the second arm are slidably connected along the axial direction, so the panel body can be smoothly rotated. In addition, by inserting a positioning pin into the overlapping part of the first hole provided in the first arm and the second hole provided in the second arm, axial sliding is restricted, so the panel body can be stopped at a designated position.

[0012] An ideal feature of a solar panel is that, in a lockable configuration, the distance between the front end of the panel body and the first wall surface is the same as or shorter than the distance between the base end of the panel body and the first wall surface.

[0013] Based on this design, by assuming a locked position during relocation, the planar footprint of the solar power generation device can be reduced. This improves the relocation efficiency of the solar power generation device.

[0014] An ideal feature of a solar panel is that it can be positioned in an open manner, such that the distance between the front end of the panel body and the first wall surface is longer than the distance between the base end of the panel body and the first wall surface.

[0015] Based on this structure, by arranging the solar panels in an open position during installation, the light-receiving area of ​​the solar panels is increased. This improves the power generation efficiency of the solar power system.

[0016] An ideal feature of a solar panel is that it has a suppressing part that inhibits rotation downwards from the panel body, and the suppressing part is rotatably connected to both the frame and the panel body.

[0017] Based on this structure, the solar panel has a restraining part that inhibits rotation downwards from the panel body, achieving a state of force balance at a designated position. Therefore, even a heavy panel body can be rotated manually.

[0018] Ideally, the ceiling panel is defined by a downward sloping surface that slopes downwards from the top toward the first panel.

[0019] Based on this structure, since the ceiling panel defines a downward sloping surface that descends from the top towards the first panel, rainwater will fall through this sloping surface. This maintains the energy storage and power supply environment within the storage space of the device. Furthermore, wind blowing towards the first wall will change direction at the downward sloping surface and rise through the gaps in the solar panels. This prevents the solar power unit from being blown away by the wind and also reduces vibration of the solar panels.

[0020] Ideally, the hammer storage section is located below the device storage section.

[0021] Based on this structure, since the weight storage part is located below the device storage part, the stability of the installation can be ensured. Attached Figure Description

Detailed Implementation

[0037] The following is for reference Figures 1-9 The present invention provides a detailed description of an embodiment 1 of the mobile solar power generation device 1 (hereinafter referred to as power generation device 1).

[0038] like Figures 1-4 As shown, the power generation device 1 includes a device storage section 10, a solar power generation panel 30 (hereinafter referred to as the power generation panel 30), and a pair of feet 51. The power generation panel 30 has two panel bodies 31. The base end 32 of the panel body 31 is rotatably connected to the support beam 24 via a rotating part R1. The support beam 24 is located at the upper end of the frame 20 that constitutes the skeleton of the device storage section 10.

[0039] The device storage section 10 defines a storage space 16a by two opposing first panels 11, two opposing second panels 12, a base plate 13, and a ceiling plate 14. The storage space 16a houses an energy storage device B. The energy storage device B is used to store electricity generated by the panel body 31. Additionally, an AC power converter can also be stored in the storage space 16a.

[0040] The device storage section 10 is roughly rectangular in plan view, with two first panel 11s and two second panel 12s facing each other and connected to the support column 21. The first panel 11 is a flat plate, with its outer side defining a first wall surface 11a. The second panel 12 is a flat plate, with its outer side defining a second wall surface 12a. The ceiling panel 14 is a convex flat plate with a descending inclined surface 14a that slopes down from the top 14T toward the first panel 11.

[0041] Below the device storage section 10 is a weight storage section 15 for storing the weight WT. The weight storage section 15 is connected to the device storage section 10 via the base plate section 13.

[0042] Ideally, the hammer should be made of heavy, easily handled parts. While this embodiment illustrates several concrete blocks, it is not limited to these. It could also be an iron block.

[0043] When the two panel bodies 31 are in a locked position, their inner surfaces 31b face the first wall surface 11a. Alternatively, the panel bodies 31 can be in an open position, where the distance between the front end 31c of the panel and the first wall surface 11a, i.e., the first distance L1, is longer than the distance between the base end 31a of the panel and the first wall surface 11a, i.e., the second distance L2 (see reference). Figure 1 , 3 Alternatively, a locking posture in which the first interval L1 and the second interval L2 are the same or shorter can be adopted (see [reference]). Figure 2 , 4 In this embodiment, although the two panel bodies are arranged facing each other, one on each side, it is not limited to this and more than two panel bodies can also be arranged facing each other. In addition, the panel bodies can also be arranged only on one side.

[0044] The power generation panel 30 also includes a posture maintaining part 40, which maintains the posture of the panel body 31. The posture maintaining part 40 includes a first arm 41, a second arm 42, and a positioning pin P. The first arm 41 is rotatably connected to the support column 21 via a first hinge 61 located in the middle of the support column 21. The second arm 42 is rotatably connected to a second shaft 82 located in the middle of the inner side surface 31b of the panel body 31 via a second hinge 62. The first arm 41 is a square tube, and the second arm 42 is a square tube that can slide while the first arm 41 is inserted. Furthermore, the first arm 41 and the second arm 42 are not limited to square tubes; for example, they can also be round tubes.

[0045] The first arm 41 and the second arm 42 are respectively provided with a first hole 41a and a second hole 42a. When the first hole 41a and the second hole 42a are overlapped, the positioning pin P is inserted into the first hole 41a and the second hole 42a, thus forming a structure that can maintain a specified position.

[0046] Rotation downwards toward the panel body 31 is suppressed by a gas spring GS (suppression part). One end of the gas spring GS is rotatably connected to the upper end of the support column 21 (below the rotating part R1), and the other end is rotatably connected to the vicinity of the second shaft 82 of the shaft mounting part 35. Thanks to the effect of the gas spring GS, the solar panel 30 can be easily switched on and off manually. In addition, while maintaining the posture of the panel body 31, by inserting the positioning pin P into the first hole 41a and the second hole 42a provided in the first arm 41 and the second arm 42, the panel body 31 can maintain its posture and not rotate even if it is subjected to external forces such as wind.

[0047] A pair of feet 51 are rotatably connected to the frame portion 20 via rotating ends 52. The feet 51 can be positioned in an open stance, and with the front end 53 spaced apart from the rotating end 52, they are grounded to the mounting surface (see reference). Figure 1 , 3 At the same time, a closed-leg posture can be adopted, forming a state where the distance between the individual front ends 53 is shorter than the width of the second panel 12. Specifically, a pair of feet 51 can stand up and be almost parallel (see reference). Figure 2 , 4 ).

[0048] like Figure 5As shown, the frame 20 has four support pillars 21 rising from the base 22. The support pillars 21 are positioned at the four corners of the device storage section 10, and the first panel 11 and the second panel 12 are connected and fixed together. (Ref) Figure 1 , 3 The base 22 is the frame structure for mounting the weight WT and forms part of the weight storage section 15. A support beam 24 is mounted on the upper end of the support column 21. The support beam 24 is a part that extends in the long side direction DL.

[0049] At the lower end of the support column 21, a mounting part 27 for mounting the base plate 13 is connected. A connecting member 23 extending in the short side direction DS is connected to the upper end, and a support beam 24 extending in the long side direction DL is also erected. Additionally, a reinforcing member 25 is installed to reinforce the support column 21. Furthermore, a mounting part 26 is installed between the connecting member 23 and the reinforcing member 25 to mount the ceiling panel 14. In this embodiment, the three reinforcing members 25 extending in the short side direction are installed facing each other, but this is not a limitation. For example, the number may be one, two, or four or more. Alternatively, they may be installed around all four sides.

[0050] like Figure 6 As shown, a shaft mounting part 35 is installed on the inner side 31b of the panel body 31. The first shaft 81 and the second shaft 82 are connected and fixed to the panel body 31 through the shaft mounting part 35. In addition, the panel body 31 is reinforced by the shaft mounting part 35.

[0051] The first shaft 81 is rotatably connected to the support beam 24 via the rotating part R1. In addition, the second shaft 82 is rotatably connected to the second arm 42 via the second hinge 62, and is also rotatably connected to the gas spring GS.

[0052] Figure 7 This is a partial oblique view of the rotating end 52 of the foot 51 when it is in an open-leg posture. The foot 51 is rotatably mounted on the base 22 via a foot rotation hinge 57. The foot 51 is fixed by a foot fixing metal part 54 to maintain the open-leg posture. In addition, when the foot 51 is in an open-leg posture, the front ends 53 of the pair of feet 51 are in a state where they can be grounded with the mounting surface 100, supporting the device storage part 10, etc.

[0053] When foot 51 is in a closed position, its position is maintained by inserting metal part 55 and abutment plate 56. Specifically, as Figure 8 As shown, with the foot 51 in contact with the abutment plate 56, a metal part 55 is inserted into the hole 51a provided in the foot 51. In this way, the rotation of the foot 51 can be stopped.

[0054] like Figure 9As shown in (a) and (b), when the power generation panel 30 is in the locked state, the second arm 42 will penetrate the first arm 41 and extend from the upper end of the support column 21 toward the base 22.

[0055] The following describes the procedure for moving and setting up the power generation device 1 in this embodiment 1.

[0056] When the power generation device 1 is moved, Figure 2 In this state, the power generation device 1 is placed on the transfer vehicle. That is, the power generation plate 30 maintains a locked posture, and the foot 51 maintains a closed posture. Furthermore, to maintain the closed posture, the foot 51 is inserted into the insertion hole 51a of the metal part 55 while maintaining the closed posture. In addition, while maintaining the locked posture, the positioning pin P is inserted into the first hole 41a and the second hole 42a where the first arm 41 and the second arm 42 overlap. The method of maintaining the closed posture is not limited to this; a locking metal part (not shown) provided on the support column 21 can also be used to directly lock the power generation plate 30. Alternatively, the two methods described above can be used in combination.

[0057] Ideally, the device storage unit 10 should pre-store the necessary devices for power generation, such as the energy storage device B and the converter, and be transferred while connected to the power generation board 30. This way, the power generation device 1 can be used directly after installation. Ideally, when not connected to the necessary devices for power generation via the power generation board 30, a separate connector for easy connection should be provided.

[0058] Furthermore, it is ideal that the weight WT is not stored in the weight storage section 15, but is transferred separately. This makes it easier to stack the power generation device 1 onto the transfer vehicle and unload it from the transfer vehicle. In addition, to make the transfer more stable, the power generation device 1 can also be transferred with the weight WT stored in the weight storage section 15.

[0059] After the transfer is completed, the power generation device 1 is unloaded and placed in the pre-designated installation location. Simultaneously, the insert metal part 55 inserted into the hole 51a is removed, and the foot 51 is rotated into an open-leg position. The foot fixing metal part maintains the open-leg position of the foot 51. In this state, the front end 53 of the foot 51 contacts the installation surface, supporting the power generation device 1. This ensures the stability of the power generation device 1 and prevents it from easily tipping over. Furthermore, by storing the counterweight WT in the counterweight storage part 15, the stability of the power generation device 1 is further ensured, preventing it from easily tipping over.

[0060] Remove the locating pin P, allowing the first arm 41 and the second arm 42 to slide axially. This releases the locked position of the solar panel 30. Manually rotate the solar panel 30 to the designated open position. The two solar panels 30 can rotate independently, so they do not need to be in the same open position. Assess local conditions and determine the appropriate open position for each solar panel 30, maintaining its open position using the locating pin P.

[0061] The generator plate 30 usually requires a lot of force to rotate, but thanks to the action of the gas spring GS, it does not require a particularly large force and can be operated manually.

[0062] When the two panel bodies 31 are in the open state, there is a certain gap between them. Part of the wind blowing towards the first panel 11 rises along the descending inclined surface 14a as it passes through the ceiling panel 14, and then passes through the gap between the two panel bodies 31. This reduces the likelihood of the power generation device 1 being blown away by the wind.

[0063] When transferring from the location of installation to the storage location, the procedure is the reverse of the above procedure.

[0064] Reference Figures 10-16 This section details Embodiment 2 of the present invention. Since it includes content that is repeated in Embodiments 1 and 2, the differences will be primarily described. The structures corresponding to Embodiment 1 are assigned numbers starting with 200.

[0065] like Figures 10-12 As shown, the power generation device 201 has a power generation plate 230 with three panel bodies 231 on each side, totaling six. Additionally, there are three pairs of feet 251 on each side. Specifically, one pair of feet 251 is located at each end and in the middle.

[0066] The feet 251 are rotatably mounted on the bottom surface of the base 222 via rotating ends 252. The feet 251 are secured by foot fixing devices 254 to maintain an open-leg posture. Furthermore, when the feet 251 are in an open-leg posture, the front ends 253 of the pair of feet 251 are in a state where they can be grounded on the mounting surface 100, supporting the device storage section 210, etc. When the feet 251 move from an open-leg posture to a closed-leg posture, or from a closed-leg posture to an open-leg posture, they rotate along a parallel surface on the bottom surface of the base 222.

[0067] The posture maintaining unit 240 includes a first arm 241 and a second arm 242. The first arm 241 is rotatably connected to the support column 221 via a first hinge 261 provided in the middle portion of the support column 221. The second arm 242 is rotatably connected to a second shaft 282 provided in the middle portion of the inner side surface 231b of the panel body 231 via a second hinge 262. The first arm 241 is a square tube, and the second arm 242 is a square tube that can slide while the first arm 241 is inserted.

[0068] When the generator panel 230 is in the locked state, the second arm 242 extends through the first arm 241 and extends from the base 222 toward the upper end of the support column 221. As described above, the first arm 241 and the second arm 242 exhibit actions different from those in embodiment 1.

[0069] The first arm 241 and the second arm 242 are respectively provided with a first hole 241a and a second hole 242a. When the first hole 241a and the second hole 242a overlap, the positioning pin P is inserted into the first hole 241a and the second hole 242a to form a structure that can maintain a specified position.

[0070] like Figure 12 As shown, the first panel 211 is composed of several single-door structures, forming a structure in which the energy storage device B and the like can be easily installed, removed, and stored in the device storage section 210.

[0071] like Figures 13-16 As shown, the foot 251 is rotatably mounted on the base 222 via the rotating end 252. Unlike embodiment 1, the foot 251 rotates along a parallel plane on the bottom surface of the base 222. The foot 251 maintains both closed and open leg positions via the foot fixing device 254 provided at the rotating end 252.

[0072] The foot fixing device 254 includes a rotation limiting band 255 and a rotation stop bolt 256. Loosening the rotation limiting band 255 and simultaneously removing the rotation stop bolt 256 allows the foot 251 to rotate. Furthermore, the tightness of the rotation limiting band 255 can be adjusted to allow rotation of the foot 251 under appropriate load. Installing the rotation stop bolt 256 prevents rotation of the foot 251.

[0073] This embodiment is exemplified, and modifications can be made without departing from the technical concept of this invention, which goes without saying.

[0074] The electrical device of the present invention is a device that can immediately supply power after relocation. It can be used in a short time at disaster sites with urgent needs, making a significant contribution to disaster recovery.
