Description

Technical Field

[0001] This utility model relates to the field of photovoltaic installation technology, specifically a flexible photovoltaic module support device. Background Technology

[0002] Flexible solar photovoltaic (PV) panels are an emerging technology product in the global solar energy industry. They are solar panels made by laying resin-encapsulated amorphous silicon, with the main photoelectric element layer, flat on a flexible substrate. Solar photovoltaic (PV) power generation systems utilize the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. They can operate independently or be connected to the grid. During installation, PV panels are typically mounted using brackets.

[0003] Currently, utility model publication CN220401671U proposes a flexible solar photovoltaic mounting bracket. This design has a simple structure and is easy to use. By adjusting the vertical and horizontal angles of the flexible solar panel, direct sunlight can be directed onto the flexible solar panel, thereby improving the solar energy conversion efficiency. It includes a mounting plate with four mounting pieces installed on its outer side. A rotating mechanism is located at the top of the mounting plate, connected to a rotating plate. A pushing mechanism is also located at the top, connected to a pushing bar. The pushing bar is slidably connected to the top of the rotating plate. Two diagonal braces are rotatably mounted on the top of the pushing bar, and the same photovoltaic support plate is rotatably mounted on the two diagonal braces. A flexible solar panel is mounted on the photovoltaic support plate. Two vertical rods are fixedly mounted on the top of the rotating plate, with the top ends of both vertical rods rotatably connected to the bottom of the photovoltaic support plate. The photovoltaic support plate has a rectangular structure.

[0004] However, the above-mentioned existing technologies still have the following shortcomings when in use: 1. The flexible solar panels do not have a flipping function. Since the back of the flexible solar panels contains electrical components and connecting lines, there is a defect that the maintenance of flexible solar panels is inconvenient; 2. The flexible solar panels have a horizontal rotation function in place. The purpose of this horizontal rotation function is to make the flexible solar panels meet the sunlight to the maximum extent. However, this horizontal rotation structure is prone to causing interference to the surrounding area. That is to say, the solar panels are usually square. When the square solar panels rotate, their corners tend to increase the space occupied.

[0005] Therefore, this utility model provides a flexible photovoltaic module support device. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a flexible photovoltaic module support device to solve the problems mentioned in the background technology. This utility model has the advantages of facilitating the flipping and maintenance of flexible photovoltaic panels, and also has the advantages of not occupying the surrounding space when adjusting the flexible photovoltaic panels and the angle of direct sunlight.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a flexible photovoltaic module support device, including a base and a flexible photovoltaic panel, wherein a lifting rod one and a lifting rod two are fixedly connected to the top of the base, and a positioning frame is rotatably connected between the moving ends of the lifting rod one and the lifting rod two, and the positioning frame is also respectively rotatably engaged with the moving ends of the lifting rod one and the lifting rod two, the flexible photovoltaic panel is fixedly installed in the positioning frame, and a control motor is provided on the lifting rod two for controlling the positioning frame to rotate in the same direction relative to the lifting rod one and the lifting rod two.

[0008] Furthermore, the moving end of the first lifting rod is rotatably connected to an upper guide sleeve, the moving end of the second lifting rod is rotatably connected to a lower guide sleeve, an upper support shaft fitted inside the upper guide sleeve is fixedly connected to the middle of one end of the positioning frame, the upper support shaft and the upper guide sleeve are rotatably and slidably engaged, and a lower support shaft fitted inside the lower guide sleeve is fixedly connected to the middle of the other end of the positioning frame, the lower guide sleeve and the lower support shaft are rotatably engaged.

[0009] Furthermore, the control motor is fixedly mounted at one end of the lower guide sleeve, and its output shaft is fixedly connected to one end of the lower support shaft.

[0010] Furthermore, the positioning frame is a square frame structure with an annular baffle welded inside for supporting the flexible photovoltaic panel. The inner peripheral wall of the positioning frame is fitted with a clearance fit to the outer peripheral wall of the flexible photovoltaic panel. A locking bolt is screwed onto the upper end face of the positioning frame, and a pressure plate is sleeved on the locking bolt.

[0011] Furthermore, a shock-absorbing rubber strip is adhered to the upper end face of the annular baffle, and a silicone pad is adhered to the lower end face of the pressure plate.

[0012] Furthermore, a pad is fixedly installed on the base near the side, and a shock-absorbing pad is adhered to the top of the pad.

[0013] Furthermore, the lifting rod one and the lifting rod two are either an electric telescopic rod or a control cylinder.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting up lifting rod one and lifting rod two, can realize the up-and-down swing adjustment of the front and rear ends of the flexible photovoltaic panel. Then, by setting up a control motor, the flexible photovoltaic panel can be controlled to rotate through the positioning frame, thereby realizing the up-and-down swing adjustment of the left and right ends. This setting makes it easy to control the flexible photovoltaic panel to flip in a horizontal state, so that the electrical components on the back of the flexible photovoltaic panel are exposed, which has the advantage of convenient maintenance.

[0016] 2. The flexible photovoltaic panel of this utility model does not have a horizontal rotation function while satisfying the function of universal adjustment to accommodate direct sunlight. Therefore, it does not increase the space occupied by the surrounding area and will not interfere with the surrounding objects, thus improving the applicability of this support device.

[0017] 3. The positioning frame of this utility model has a self-rotation function. When the positioning frame is in a horizontal state, it can easily move and disassemble the flexible photovoltaic panel on it in an almost horizontal manner during the self-rotation, which has the advantage of saving effort in replacing the flexible photovoltaic panel.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1 to 3This utility model provides a technical solution: a flexible photovoltaic module support device, including a base 1 and a flexible photovoltaic panel 2. A lifting rod 3 and a lifting rod 4 are fixedly connected to the top of the base 1. The lifting rod 3 and the lifting rod 4 are either electric telescopic rods or control cylinders. A positioning frame 5 is rotatably connected between the moving ends of the lifting rod 3 and the lifting rod 4. The positioning frame 5 also rotates vertically with the moving ends of the lifting rod 3 and the lifting rod 4 respectively. When the lifting rod 3 and the lifting rod 4 rise and fall, they can drive the front and rear ends of the positioning frame 5 to swing up and down. The flexible photovoltaic panel 2 is fixedly installed inside the positioning frame 5. The second lifting rod 4 is equipped with a control motor 6 for controlling the positioning frame 5 to rotate in the same direction relative to the first lifting rod 3 and the second lifting rod 4. The function of the control motor 6 is to control the left and right ends of the positioning frame 5 to swing up and down. Thus, the lifting and lowering movements of the first lifting rod 3 and the second lifting rod 4, as well as the rotation movement of the positioning frame 5, facilitate the adjustment of the angle between the flexible photovoltaic panel 2 and the sunlight in place, without causing any interference to the surrounding area. At the same time, when the positioning frame 5 rotates 180°, the back of the flexible photovoltaic panel 2 can be fully exposed, which is convenient for maintenance.

[0024] Specifically, the operating end of lifting rod 3 is rotatably connected to an upper guide sleeve 31, and the operating end of lifting rod 4 is rotatably connected to a lower guide sleeve 41. An upper support shaft 51, fitted inside the upper guide sleeve 31, is fixedly connected to the middle of one end of the positioning frame 5. The upper support shaft 51 and the upper guide sleeve 31 are in a rotatable and sliding fit; in practice, a clearance fit between the upper support shaft 51 and the upper guide sleeve 31 is sufficient. A lower support shaft 52, fitted inside the lower guide sleeve 41, is fixedly connected to the middle of the other end of the positioning frame 5. The lower guide sleeve 41 and the lower support shaft 52 are in a rotatable fit; alternatively, a clearance fit can also be used.

[0025] Furthermore, the control motor 6 is fixedly mounted at one end of the lower guide sleeve 41 and its output shaft is fixedly connected to one end of the lower support shaft 52. The control motor 6 can drive the positioning frame 5 to rotate by driving the lower support shaft 52 to rotate.

[0026] In this embodiment, the positioning frame 5 is a square frame structure with an annular baffle 7 welded inside for supporting the flexible photovoltaic panel 2. The annular baffle 7 is a square frame structure, and the outer peripheral wall of the positioning frame 5 is fitted with a clearance, which means that the difficulty of docking the flexible photovoltaic panel 2 and the positioning frame 5 is reduced. The upper end face of the positioning frame 5 is screwed with a locking bolt 8, and a pressure plate 9 is sleeved on the locking bolt 8. When the locking bolt 8 is tightened, the pressure plate 9 will press against the flexible photovoltaic panel 2, which has the function of locking the flexible photovoltaic panel 2 onto the positioning frame 5. The pressure plate 9 can rotate relative to the locking bolt 8. When the locking bolt 8 is loosened and the pressure plate 9 is swung outward from the flexible photovoltaic panel 2, it is convenient to remove the flexible photovoltaic panel 2.

[0027] Furthermore, a shock-absorbing strip 71 is bonded to the upper end of the annular baffle 7, and a silicone pad 91 is bonded to the lower end of the pressure plate 9. The function of the shock-absorbing strip 71 and the silicone pad 91 is to protect the flexible photovoltaic panel 2 and prevent it from being squeezed and damaged when it is fixed.

[0028] In this embodiment, a platform 11 near the side is fixedly installed on the base 1. A shock-absorbing pad 101 is adhered to the top of the platform 11. When it is necessary to disassemble the flexible photovoltaic panel 2, the flexible photovoltaic panel 2 is controlled to be in a horizontal position by lifting rod 1 3 and lifting rod 2 4. Then, the control positioning frame 5 is rotated to the bottom position close to and lower than the shock-absorbing pad 101. At this time, the flexible photovoltaic panel 2 can be transferred to the shock-absorbing pad 101 with less effort. It has the advantage of making the installation and disassembly of the flexible photovoltaic panel 2 more effortless.

[0029] Working principle: When the back of the flexible photovoltaic panel 2 needs to be inspected, the lifting rod 1 3 and lifting rod 2 4 are activated to bring the flexible photovoltaic panel 2 to a horizontal position. Then, the control motor 6 is started to rotate the positioning frame 5. At this time, the wiring and components on the back of the flexible photovoltaic panel 2 will be fully exposed, making inspection and maintenance more intuitive. When the flexible photovoltaic panel 2 needs to be disassembled and replaced, the positioning frame 5 is also kept in a horizontal state. Then, the positioning frame 5 is rotated to an inclined state. The locking bolt 8 is loosened with a tool, and then the pressure plate 9 is twisted. Finally, the flexible photovoltaic panel 2 is manually pushed outward from the current back of the positioning frame 5 to a vertical position. It can then be easily moved onto the shock-absorbing pad 101 to remove the current flexible photovoltaic panel 2. The new flexible photovoltaic panel 2 can then be installed in the same way.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
