Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation device technology, specifically to a foldable photovoltaic power generation device. Background Technology

[0002] Photovoltaic power generation devices are key equipment for converting solar energy into electrical energy. They are devices that directly convert light energy into electrical energy by utilizing the photovoltaic effect at the semiconductor interface. Solar energy has become a focus of attention due to its unique advantages. Abundant solar radiation energy is an important energy source that is inexhaustible, pollution-free, inexpensive, and freely usable by humans, and therefore it is widely used.

[0003] Chinese utility model patent CN219918786U discloses a portable foldable solar photovoltaic power generation device, which includes "a photovoltaic panel A and a housing connected by a rotating mechanism, and a photovoltaic panel B and a housing connected by a sliding mechanism, so that both photovoltaic panels A and B can absorb sunlight, solving the technical problem that the current photovoltaic panels do not receive much sunlight per unit area"; however, the photovoltaic panels A and B are positioned at different heights, which means that at a certain angle, some areas of photovoltaic panel B will not receive sunlight, resulting in shadow areas, thus affecting the efficiency of sunlight reception and reducing the subsequent power generation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a foldable photovoltaic power generation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a foldable photovoltaic power generation device, including an outer frame of the power generation device, wherein a photovoltaic module is slidably connected to the inner side of the outer frame of the power generation device.

[0006] The outer frame of the power generation device includes a box, a placement plate is fixedly connected to one side of the inner side of the box, sliding grooves are opened at both ends of the inner side of the box, and a box cover is hinged to both ends of the top of the box.

[0007] The photovoltaic module includes a limiting post slidably connected to the inner side of a sliding groove. A fixing block is rotatably connected to one end of the limiting post. A first photovoltaic panel is fixedly connected to the top of the fixing block. A bracket is installed on one side of each end of the first photovoltaic panel. A second photovoltaic panel is installed on the other side of one end of each bracket. A pad is installed on one side of the top of both the first and second photovoltaic panels. A fixing plate is installed on one side of both the first and second photovoltaic panels. A threaded post is threadedly connected to one side of the fixing plate. A handle is fixedly connected to one side of the threaded post.

[0008] The beneficial effects of this utility model are as follows: The photovoltaic module allows the first and second photovoltaic panels to be folded, facilitating storage in the housing and increasing portability. Simultaneously, the first and second photovoltaic panels can be unfolded, and after unfolding, they can slide within the sliding groove via limiting posts, allowing them to extend out of the housing. After extending, threaded posts can enter the limiting holes, thus limiting the first and second photovoltaic panels and preventing them from falling off. This ensures the first and second photovoltaic panels are on the same horizontal line, effectively preventing localized shading and maintaining consistent sunlight absorption, thereby significantly improving subsequent power generation efficiency.

[0009] To ensure that the first and second photovoltaic panels can work effectively:

[0010] Further configuration: the external dimensions of the limiting post are consistent with the internal dimensions of the sliding groove.

[0011] By adopting the above technical solution, the limiting column can slide inside the sliding groove, thereby driving the first photovoltaic panel and the second photovoltaic panel to extend out of the box, thus enabling effective solar energy absorption and subsequent power generation.

[0012] To prevent the first and second photovoltaic panels from colliding after being folded:

[0013] A further feature is provided: an elastic pad is mounted on the top of the pad.

[0014] By adopting the above technical solution, the pads can abut against each other after the first photovoltaic panel and the second photovoltaic panel are folded, and the elastic pads can reduce damage during the abutment process, thereby effectively avoiding the collision between the first photovoltaic panel and the second photovoltaic panel after folding.

[0015] To enable limiting the position of the first and second photovoltaic panels:

[0016] Further configuration: Limiting holes are provided at the center of the upper part of both sides of the box.

[0017] By adopting the above technical solution, after the first photovoltaic panel and the second photovoltaic panel are unfolded, the threaded column can be moved horizontally by rotating the handle, and then enter the limiting hole, thereby limiting the first photovoltaic panel and the second photovoltaic panel and preventing them from falling off.

[0018] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0024] Please see Figures 1 to 3 A foldable photovoltaic power generation device includes an outer frame 1 for the power generation device, and a photovoltaic module 2 is slidably connected to the inner side of the outer frame 1.

[0025] The outer frame 1 of the power generation device includes a box 101. A placement plate 102 is fixedly connected to one side of the inner side of the box 101. Sliding grooves 103 are provided at both ends of the inner side of the box 101. A box cover 104 is hinged to both ends of the top of the box 101.

[0026] The photovoltaic module 2 includes a limiting post 201 slidably connected to the inner side of the sliding groove 103. A fixing block 202 is rotatably connected to one end of the limiting post 201. A first photovoltaic panel 203 is fixedly connected to the top of the fixing block 202. A bracket 204 is installed on one side of both ends of the first photovoltaic panel 203. A second photovoltaic panel 205 is installed on the other side of one end of the bracket 204. A pad 206 is installed on one side of the top of both the first photovoltaic panel 203 and the second photovoltaic panel 205. A fixing plate 207 is installed on one side of both the first photovoltaic panel 203 and the second photovoltaic panel 205. A threaded post 208 is threadedly connected to one side of the fixing plate 207. A handle 209 is fixedly connected to one side of the threaded post 208.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the external dimensions of the limiting post 201 are consistent with the internal dimensions of the sliding groove 103.

[0028] In this embodiment, as Figure 1 and Figure 3 As shown, a resilient washer is installed on the top of the pad 206.

[0029] In this embodiment, as Figure 1 and Figure 2 As shown, limit holes are provided at the center of the upper part of both sides of the box 101.

[0030] The working process of this foldable photovoltaic power generation device is as follows:

[0031] First, move the device to the corresponding area, then open the cover 104. At this time, the first photovoltaic panel 203 and the second photovoltaic panel 205 are in a folded state. Then, grasp one side of the first photovoltaic panel 203 and the second photovoltaic panel 205 and drag it to the right. At this time, the limiting post 201 will slide from left to right inside the sliding groove 103. When it moves to the right side of the sliding groove 103, the first photovoltaic panel 203 and the second photovoltaic panel 205 will extend out of the box 101, so that the bottom of the first photovoltaic panel 203 will contact the top side of the box 101, and one side of the fixing plate 207 will fit against one side of the box 101. At this time, the handle 209 can be rotated to drive the threaded post 208 to rotate and move horizontally, so that the threaded post 208 enters the limiting hole, thus completing the limiting work of the first photovoltaic panel 203. Then rotate the second photovoltaic panel 205 so that the bottom of the second photovoltaic panel 205 contacts the other side of the top of the box 101, and the threaded post 207... 8. Enter the limiting hole, thus completing the limiting work of the second photovoltaic panel 205, which can absorb sunlight and then carry out subsequent power generation. When it is necessary to retract, the handle 209 can be rotated to drive the threaded post 208 to rotate, so that the threaded post 208 disengages from the limiting hole, thereby canceling the limiting work of the first photovoltaic panel 203 and the second photovoltaic panel 205. The first photovoltaic panel 203 and the second photovoltaic panel 205 are model Hi-MO7. Then, the first photovoltaic panel 203 and the second photovoltaic panel 205 are folded. At this time, the pads 206 will contact each other, and the elastic pads will minimize damage. Then push the first photovoltaic panel 203 and the second photovoltaic panel 205 to the left. At this time, the limiting post 201 will slide from right to left inside the sliding groove 103. When it moves to the leftmost side, the first photovoltaic panel 203 and the second photovoltaic panel 205 are retracted into the box 101 and supported by the placement plate 102. Finally, the box cover 104 is closed.
