Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic modules, and particularly to a photovoltaic module bracket that can be quickly stored under strong wind conditions. Background Art

[0002] A photovoltaic module is a device that directly converts light energy into electrical energy, mainly composed of photovoltaic cells, encapsulation materials, and other auxiliary components. The core components of a photovoltaic module include: 1. Photovoltaic cells: This is the key part that converts light energy into electrical energy, usually made of semiconductor materials such as silicon. Photovoltaic cells work through the photovoltaic effect, that is, when light irradiates on the semiconductor, electrons in the material are excited to form an electric current. 2. Encapsulation materials: Include glass, backsheet, and EVA (ethylene-vinyl acetate copolymer) film, etc. These materials are used to protect the photovoltaic cells from environmental factors such as ultraviolet rays, humidity, and temperature changes. 3. Frame: Used to fix and protect the photovoltaic cells, usually made of aluminum alloy, with high strength and the ability to resist mechanical impacts. 4. Electrical connection devices: Include solder tapes and junction boxes. Solder tapes are used to connect the cell pieces, and the junction box is responsible for transmitting the generated current to the external circuit.

[0003] Photovoltaic modules installed outdoors are generally installed on the ground through fixed brackets. For example, the patent publication number CN211981799 U discloses a photovoltaic bracket assembly, including: a photovoltaic panel; purlins provided on both sides of the photovoltaic panel, and an installation groove for installing the photovoltaic panel is provided on the side edge of the purlin, and the installation groove extends along the length direction of the purlin; a filling part provided between the photovoltaic panel and the groove wall of the installation groove to fill the gap between the photovoltaic panel and the groove wall of the installation groove, and at least one of the photovoltaic panel and the installation groove can slide relative to the filling part. The filling part is provided between the photovoltaic panel and the groove wall of the installation groove to fill the gap between the installation groove and the groove wall, so that one edge of the photovoltaic panel is completely in contact with the purlin. Under the action of strong wind or external force, the photovoltaic panel is subjected to a force, and the contact area between the photovoltaic panel and the purlin is large, and the force is completely dispersed to each position on the edge of the photovoltaic panel, dispersing the stress and not easily causing damage to the photovoltaic panel.

[0004] When strong wind occurs, the photovoltaic panel is easily overturned or damaged under the action of the wind force. When encountering hail, rain, or snow weather, it may cause damage to the photovoltaic panel, resulting in the inability of the photovoltaic panel to be used normally. In addition, after experiencing bad weather, the surface of the photovoltaic panel will also get dirty, which will affect the sunlight absorption efficiency of the photovoltaic panel and thus affect the service life of the photovoltaic panel.

[0005] The patent publication number is CN 205584916 U, which discloses a photovoltaic greenhouse installed with a flipable solar photovoltaic module. A bracket and a solar photovoltaic panel are installed on the shed roof. On the bracket, there are a rotation axis mounting frame and a fixture mounting frame that are mutually perpendicular at 90°. A rotation axis driven by a motor is installed at the center of the rotation axis mounting frame. The solar photovoltaic panel is fixed on the rotation axis. A transparent protective film covers the bottom of the solar photovoltaic panel. The fixture mounting frame is equipped with a movable fixture that can fix the solar photovoltaic panel. The utility model can provide energy for the photovoltaic greenhouse when the sun is sufficient, and when encountering bad weather, turn the side with the protective film upwards to protect the solar photovoltaic panel, extending the service life of the photovoltaic module;

[0006] Although the above patent can achieve protection under strong wind by flipping, it has not been implemented in actual application. Although the above patent can achieve flipping, in the actual use process, for the fixation of the solar photovoltaic panel by the movable fixture before and after flipping, it is necessary to manually control the movable plate on the movable fixture to fully open first, loosen the clamping of the solar photovoltaic panel, and then manually control the movable fixture to clamp and fix it after flipping. This process has too many human factors. Moreover, solar photovoltaic panels are generally placed at high places, and when a large number of photovoltaic panels are arranged and used in batches, it is impossible for humans to operate. Therefore, the operation is extremely inconvenient and impossible to implement; thus, its structure needs to be improved and optimized. Summary of the Invention

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0033] Please refer to Figures 1-7 , the present invention provides a technical solution: a photovoltaic module bracket that can be quickly stored under strong wind conditions. Through the setting of the protection unit, in strong wind weather, the protection unit can protect the surface of the photovoltaic panel. In addition, the lifting unit drives the mounting frame to move downward, so that the photovoltaic panel moves downward, avoiding the photovoltaic panel with a high installation position being overturned when the wind force is large; the specific structure is as follows: it includes a base 1 installed on the outdoor ground through expansion bolts. On both sides of the length direction of the base 1, two hinge rods 5 are respectively hinged. The upper ends of the four hinge rods 5 are jointly hinged to a mounting frame 14. A photovoltaic panel 10 is installed on the mounting frame 14. One end of the mounting frame 14 is horizontally rotatably connected to a winding shaft 17. A protective part 8 is wound on the winding shaft 17. Corresponding to the two axial ends of the winding shaft 17 on the mounting frame 14, two sliding seats are horizontally slidably connected. A cloth pulling shaft 9 is horizontally rotatably connected to the two sliding seats together;

[0034] A blind hole-shaped installation groove is opened on the mounting frame 14. A volute spring 7 is installed in the installation groove. The volute spring 7 is wound around the cloth pulling shaft 9, and the two ends in the elastic force direction are respectively fixedly connected to the inner wall of the installation groove and the cloth pulling shaft 9. In the initial state, through the elastic potential energy of the volute spring 7, the volute spring 7 drives the winding shaft 17 to rotate, thereby winding the protective cloth. In addition, when the cloth pulling shaft 9 moves in the direction away from the winding shaft 17, the cloth pulling shaft 9 can pull the protective cloth 8, so that the protective cloth 8 is unwound on the winding shaft 17. When unwinding, the winding shaft 17 drives the volute spring 7 to be in a scattered state, so that the volute spring 7 accumulates elastic potential energy;

[0035] A servo motor 6 is installed on the sliding seat. The output shaft of the servo motor 6 is fixedly sleeved with a gear 18. A U-shaped bracket 13 is welded to the side wall of the mounting frame 14. The middle section of the bracket 13 has a rectangular longitudinal section. A sliding hole for the free passage of the middle section of the bracket 13 is provided on the sliding seat. A rack portion is provided on the middle section of the bracket 13. The gear 18 meshes with the rack portion. By driving the gear to rotate through the servo motor, the meshing transmission between the gear and the rack portion is achieved, thereby driving the sliding seat to move linearly on the mounting frame. During the movement, the cloth pulling shaft can pull the protective cloth to unwind on the winding shaft, so that the protective portion can cover the surface of the photovoltaic panel, thereby protecting the photovoltaic panel. The structure is simple and the operation is convenient.

[0036] A connecting cylinder 2 is hinged to the base 1. The inside of the connecting cylinder 2 is hollow. One of the hinge rods 5 is hinged with a telescopic rod 4. The end of the telescopic rod 4 away from the hinge rod 5 penetrates into the connecting cylinder 2. The telescopic rod 4 slides freely in the connecting cylinder 2. And the end of the telescopic rod 4 penetrating into the connecting cylinder 2 is coaxially fixedly connected with a first piston 19. The first piston 19 slides freely in the connecting cylinder 2. A first connection port 3 is provided on the outer wall of the connecting cylinder 2. The first connection port 3 communicates with the inside of the connecting cylinder 2. A gas charging cylinder 11 is horizontally and fixedly connected to the mounting frame 14. A second connection port 12 is provided on the end face of the closed end of the gas charging cylinder 11. The second connection port 12 communicates with the first connection port 3 through a trachea. A second piston 16 is clamped in the gas charging cylinder 11. The second piston 16 slides freely in the gas charging cylinder 11. A push rod 15 is fixedly connected to the sliding seat. The end of the push rod 15 away from the sliding seat is fixedly connected to the end face of the second piston 16.

[0037] When the sliding seat moves in the direction away from the winding shaft 17, the movement of the sliding seat will drive the push rod 15 to move, so that the push rod 15 drives the second piston 16 to slide in the gas charging cylinder 11, and then the air in the gas charging cylinder 11 is squeezed to the second connection port 12, and then enters the connecting cylinder 2 through the second connection port 12 and the first connection port 3, so as to be able to make the first piston 19 in the connecting cylinder 2 move downward, so that the telescopic rod 4 moves in the direction of shrinking into the connecting cylinder 2, and then makes the mounting frame 14 move downward. Furthermore, when protecting the photovoltaic panel 10, the photovoltaic panel 10 is also moved downward at the same time, avoiding the phenomenon that the photovoltaic panel 10 is overturned under strong wind conditions. Through the horizontal movement of the sliding seat, the push rod is driven to move, so that the push rod drives the second piston to slide in the gas charging cylinder, and then the air in the gas charging cylinder is squeezed to the second connection port, and then enters the connecting cylinder through the second connection port and the first connection port, so as to be able to make the first piston in the connecting cylinder move downward, so that the telescopic rod moves in the direction of shrinking into the connecting cylinder, and then makes the mounting frame move downward. Furthermore, when protecting the photovoltaic panel, the photovoltaic panel is also moved downward at the same time.

[0038] The working principle of the present invention:

[0039] Remotely connect the power supply of the servo motor 6, so that the servo motor 6 drives the gear 18 to rotate. The gear 18 meshes with the rack portion, and then drives the sliding seat to move horizontally in the middle section of the bracket 13. When the sliding seat moves horizontally, it will drive the cloth pulling shaft 9 to move. When the cloth pulling shaft 9 moves in the direction away from the winding shaft 17, it can make the cloth pulling shaft 9 pull the protective cloth 8, so that the protective cloth 8 is unrolled on the winding shaft 17. When unrolling, the winding shaft 17 drives the scroll spring 7 to be in a spread state, so that the scroll spring 7 stores elastic potential energy, and then makes the protective cloth 8 in a tensioned state. In addition, when the sliding seat moves in the direction away from the winding shaft 17, the movement of the sliding seat will drive the push rod 15 to move, so that the push rod 15 drives the second piston 16 to slide in the air cylinder 11, and then squeezes the air in the air cylinder 11 to the second connection port 12, and then enters the connection cylinder 2 through the second connection port 12 and the first connection port 3. Furthermore, it can make the first piston 19 in the connection cylinder 2 move downward, so that the telescopic rod 4 moves in the direction of retracting into the connection cylinder 2, and then makes the mounting bracket 14 move downward. Furthermore, when protecting the photovoltaic panel 10, it also makes the photovoltaic panel 10 move downward at the same time, avoiding the phenomenon that the photovoltaic panel 10 is overturned under strong wind conditions.
