Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic components, and in particular to a photovoltaic component support capable of being quickly stored in a strong wind condition. Background Art

[0002] ‌Photovoltaic modules are devices that convert light energy directly into electrical energy. They are mainly composed of photovoltaic cells, packaging materials, and other auxiliary components. The core components of photovoltaic modules include: 1. Photovoltaic cells: This is the key part of converting light energy into electrical energy. It is usually made of semiconductor materials, such as silicon. Photovoltaic cells work through the photovoltaic effect, that is, when light shines on the semiconductor, the electrons in the material are excited to form an electric current. 2. Packaging materials: including glass, backplane, and EVA (ethylene-vinyl acetate copolymer) film. These materials are used to protect photovoltaic cells from environmental factors such as ultraviolet rays, humidity, and temperature changes. 3. Frame: used to fix and protect photovoltaic cells, usually made of aluminum alloy, with high strength and resistance to mechanical shock. 4. Electrical connection device: including welding ribbon and junction box, welding ribbon is used to connect the battery cells, and the junction box is responsible for transmitting the generated current to the external line.

[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: photovoltaic panels; purlins, arranged on both sides of the photovoltaic panels, and the sides of the purlins are provided with mounting grooves for mounting photovoltaic panels. The mounting grooves extend along the length direction of the purlins and are provided with: filling parts, arranged between the photovoltaic panel and the groove wall of the mounting groove, filling the gap between the photovoltaic panel and the groove wall of the mounting groove, and at least one of the photovoltaic panel and the mounting groove can slide relative to the filling part. The filling part is arranged between the photovoltaic panel and the groove wall of the mounting groove, filling the gap between the mounting 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 the force, and the contact area between the photovoltaic panel and the purlin is large. The force is completely dispersed to various positions on the edge of the photovoltaic surface, which disperses the stress and is not easy to cause damage to the photovoltaic panel.

[0004] When strong winds occur, photovoltaic panels are easily overturned or damaged under the action of wind. When encountering hail, rain or snow, the photovoltaic panels may be damaged, resulting in the inability to use them normally. In addition, after experiencing bad weather, the surface of the photovoltaic panels will become dirty, which will affect the photovoltaic panels' efficiency in absorbing sunlight and thus affect their service life.

[0005] The patent publication number is CN 205584916 U, which discloses a photovoltaic greenhouse equipped with a flippable solar photovoltaic module. A bracket and a solar photovoltaic panel are installed on the roof. The bracket is provided with a flip axis mounting frame and a clamp mounting frame that are 90 degrees to each other. A motor-driven flip axis is installed at the center of the flip axis mounting frame. The solar photovoltaic panel is fixed on the flip axis. The bottom of the solar photovoltaic panel is covered with a transparent protective film. The clamp mounting frame is equipped with a movable clamp that can fix the solar photovoltaic panel. The utility model can provide energy for the photovoltaic greenhouse when there is sufficient sunlight. When encountering bad weather, the side with the protective film can be flipped to the top to protect the solar photovoltaic panel, thereby extending the service life of the photovoltaic module. Although the above patent can achieve protection against strong winds by flipping, it is not implemented in actual application. Although the above patent can achieve flipping, in actual use, the fixation of the solar photovoltaic panel by the movable clamp before and after flipping requires manual control of the movable plate on the movable clamp to fully open and release the clamp of the solar photovoltaic panel. After flipping, the movable clamp is clamped and fixed by manual control. This process has too many manual factors, and solar photovoltaic panels are generally placed at high places. Moreover, when a large number of photovoltaic panels are arranged in batches for use, manual operation is impossible. Therefore, the operation is extremely inconvenient and it is impossible to implement it. Therefore, its structure needs to be improved and optimized. Summary of the invention

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 7 The present invention provides a technical solution: a photovoltaic component bracket that can be quickly stored under strong wind conditions. Through the setting of a protection unit, the protection unit can protect the surface of the photovoltaic panel in strong wind weather. In addition, the lifting unit drives the mounting frame to move downward, so that the photovoltaic panel moves downward, to avoid overturning the photovoltaic panel installed at a higher position when the wind is strong; the specific structure is as follows: it includes a base 1 installed on the outdoor ground through expansion bolts, two hinge rods 5 are hinged on both sides of the length direction of the base 1, and the upper ends of the four hinge rods 5 are hinged together with a mounting frame 14, and 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, and a protective portion 8 is wound on the winding shaft 17. The mounting frame 14 is horizontally slidably connected to sliding seats at both ends of the axial direction of the winding shaft 17, and the two sliding seats are horizontally rotatably connected to a cloth pulling shaft 9; The mounting frame 14 is provided with a mounting groove in the form of a blind hole, in which a vortex spring 7 is installed. The vortex spring 7 is wound around the cloth-pulling shaft 9, and the two ends in the direction of elastic force are respectively fixedly connected to the inner wall of the mounting groove and the cloth-pulling shaft 9 in a one-to-one correspondence. In the initial state, the vortex spring 7 drives the winding shaft 17 to rotate through the elastic potential energy of the vortex spring 7, thereby winding up the protective cloth. In addition, when the cloth-pulling shaft 9 moves in a 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 vortex spring 7 to spread out, so that the vortex spring 7 accumulates elastic potential energy. A servo motor 6 is installed on the sliding seat, and a gear 18 is fixedly sleeved on the output shaft of the servo motor 6. A U-shaped bracket 13 is welded to the side wall of the mounting frame 14. The longitudinal section of the middle section of the bracket 13 is rectangular. A sliding hole is provided on the sliding seat for the middle section of the bracket 13 to pass freely. A rack portion is provided in the middle section of the bracket 13, and the gear 18 is meshed with the rack portion. The gear is driven to rotate by the servo motor, so that the gear and the rack portion are meshed and transmitted, thereby driving the sliding seat to move linearly on the mounting frame. During 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.

[0020] The base 1 is hinged with a connecting tube 2, which is hollow inside. A telescopic rod 4 is hinged on one of the hinge rods 5. The end of the telescopic rod 4 away from the hinge rod 5 penetrates the connecting tube 2. The telescopic rod 4 slides freely in the connecting tube 2. The end of the telescopic rod 4 that penetrates the connecting tube 2 is coaxially fixed with a first piston 19. The first piston 19 slides freely in the connecting tube 2. A first connecting port 3 is provided on the outer wall of the connecting tube 2. The first connecting port 3 is connected to the inside of the connecting tube 2. An inflatable cylinder 11 is horizontally fixedly connected to the mounting frame 14. A second connecting port 12 is provided on the end surface of the closed end of the inflatable cylinder 11. The second connecting port 12 is connected to the first connecting port 3 through an air pipe. A second piston 16 is engaged in the inflatable cylinder 11. The second piston 16 slides freely in the inflatable cylinder 11. A push rod 15 is fixed to the sliding seat. The end of the push rod 15 away from the sliding seat is fixed to the end surface of the second piston 16. ; 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 inflation cylinder 11, and then squeezes the air in the inflation cylinder 11 to the second connecting port 12, and then enters the connecting cylinder 2 from the second connecting port 12 and the first connecting port 3, so that the first piston 19 in the connecting cylinder 2 can move downward, so that the telescopic rod 4 moves in the direction of retracting into the connecting cylinder 2, and then the mounting frame 14 moves downward, and then when protecting the photovoltaic panel 10, the photovoltaic panel 10 is moved downward at the same time to avoid the photovoltaic panel 10 being 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 inflation cylinder, thereby squeezing the air in the inflation cylinder to the second connecting port, and then entering the connecting cylinder from the second connecting port and the first connecting port, thereby enabling the first piston in the connecting cylinder to move downward, so that the telescopic rod moves in the direction of being retracted into the connecting cylinder, thereby causing the mounting frame to move downward, thereby simultaneously moving the photovoltaic panel downward while protecting the photovoltaic panel.

[0021] Working principle of the present invention: The power supply of the servo motor 6 is remotely connected, so that the servo motor 6 drives the gear 18 to rotate, and the gear 18 meshes with the rack part, thereby driving 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 pull the protective cloth 8 on the cloth pulling shaft 9, so that the protective cloth 8 is unwound on the winding shaft 17. When unwinding, the winding shaft 17 drives the vortex spring 7 to spread out, so that the vortex spring 7 accumulates elastic potential energy, thereby making the protective cloth 8 in a tensioned state. In addition, when the sliding seat moves in the direction away from the winding shaft 17, When the push rod 15 is in motion, 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 inflation cylinder 11, and then squeezes the air in the inflation cylinder 11 to the second connecting port 12, and then enters the connecting cylinder 2 from the second connecting port 12 and the first connecting port 3, so that the first piston 19 in the connecting cylinder 2 can move downward, so that the telescopic rod 4 moves in the direction of being retracted into the connecting cylinder 2, and then the mounting frame 14 moves downward, and then when the photovoltaic panel 10 is protected, the photovoltaic panel 10 is moved downward at the same time to avoid the photovoltaic panel 10 being overturned under strong wind conditions.
