[0002] During the operation of photovoltaic power generation components, a large amount of heat will be generated. The power conversion efficiency of photovoltaic power generation components will decrease as the temperature rises, which not only affects the power generation of photovoltaic power generation components, but also seriously reduces the service life of photovoltaic power generation components.

[0003] The patent with the patent announcement number CN213585697U relates to the technical field of photovoltaic power generation components, including a housing, a commutation mechanism and a locking mechanism. A disassembly plate is provided on the front of the housing. A ventilation plate is fixedly connected to the front of the disassembly plate. Ventilation holes are provided on the front of the ventilation plate. A dust-proof net is provided inside the ventilation holes. An upper cover is provided at the top of the housing. A water flow pipe is provided inside the housing. An inlet, an outlet and a control panel are provided on the side of the housing. In this patent, when the device needs to be repaired, the forward rotation of the first servo motor drives the screw to rotate, and then under the combined action of the screw and the screw hole column, the screw hole column drives the disassembly plate to move outwards, so as to achieve the purpose of easy disassembly. After disassembly, the opening can be increased, which facilitates the repair of the device, and solves the problem that the existing cooling device for photovoltaic power generation components is not easy to disassemble and is not convenient for repair.

[0004] The above patent solves the problem that the existing cooling device for photovoltaic power generation components is not easy to disassemble and is not convenient for repair.

The efficiency of the photovoltaic panel is closely related to the temperature. When the temperature is too high, the conversion efficiency of the photovoltaic cell will decrease, affecting the power generation. Summary of the Invention

[0014] The present invention provides a cooling device for a photovoltaic power generation component.

Through natural convection heat dissipation, the operation time of the cooling system can be reduced, the overall energy consumption can be lowered, the system economy can be improved, and after enhancing the air contact, the heat distribution is more uniform, local high temperature is reduced, and the service life of the photovoltaic panel is extended.

[0015] (2) In this invention, the push rod round rod limits the rotating blade to prevent the rotating blade from rotating rapidly when the power generation component is not operating due to too fast wind speed. The rapid rotation of the rotating blade may cause the support device to be accidentally touched, which may occupy space or affect subsequent installation, may lead to structural misalignment or functional locking, and increase the complexity of subsequent installation and debugging.

[0016] (3) In this invention, the movable end of the elastic telescopic rod extends out to contact the ground to enhance the support effect on the support frame. Under the action of strong winds, the support frame may be subjected to large external forces and is prone to tilting or damage. After the elastic telescopic rod extends out, the support force can be effectively enhanced to resist the action of the wind force, thereby increasing the stability of the support frame and preventing it from displacing or tilting.

[0017] (4) In this invention, when the sliding plug board moves, the limit on the support board will be released, and then the support board will be driven by the fourth torsion spring to rotate towards the direction of the rotating shaft, strengthening the support strength between the rotating shaft and the fixed plate. After the support between the fixed plate and the rotating shaft is enhanced, the influence of wind force on the structure can be effectively reduced, preventing the wind force from causing excessive relative displacement or deviation between the fixed plate and the rotating shaft, thereby improving the stability of the overall structure.

[0018] (5) In this invention, the rotating cover plate will be driven by the second torsion spring to seal the heat dissipation slots. Strong wind may cause unnecessary vibration or deviation of the photovoltaic panel, especially when the heat dissipation slots are open. The wind force may cause unstable wind force to affect the photovoltaic module. Closing the heat dissipation slots can reduce the interference of wind force on the photovoltaic module, maintain the stability and direction of the module, and ensure that they can maintain the best working state.

[0031] During the operation of this embodiment: When the cover plate 192 rotates, it will contact the inclined surface of the sliding rod 22. The movement of the sliding rod 22 will drive the round rod to move. The movement of the round rod will release the contact with the fixed slot 291, so that the rotating shaft 5 of the rotating blade 24 can be blown by the wind. The push rod round rod limits the rotating blade 24 to prevent the rotating blade 24 from rotating rapidly when the wind speed is too fast when the power generation component is not running. The rapid rotation of the rotating blade 24 may cause the support device to be accidentally touched, which may occupy space or affect subsequent installation, may cause structural misalignment or function locking, and increase the complexity of subsequent installation and debugging. When the wind force is too large, the rotating blade 24 will rotate rapidly. When the rotating blade 24 rotates rapidly, the rotating push rod 25 will rotate towards the slide plate 26 due to centrifugal force.

The movement of the first connecting rod 27 will push the ring 28 to move. The movement of the ring 28 will push the second connecting rod 29 to move. The movement of the second connecting rod 29 will push the sliding push plate 292 to move. The movement of the sliding push plate 292 will push the sliding plug rod 293 to move. The movement of the sliding plug rod 293 will release the limit on the square block 295, so that the limit of the elastic telescopic rod 294 will be released. Then the elastic telescopic rod 294 will be driven by the third torsion spring to rotate towards the side away from the support frame 11. Then the movable end of the elastic telescopic rod 294 will extend out to contact the ground to enhance the support effect on the support frame 11. Under the action of strong wind, the support frame 1 may be subjected to a large external force and is prone to tilt or damage. After the elastic telescopic rod 294 extends out, it can effectively enhance the supporting force and resist the action of the wind force, thereby increasing the stability of the support frame 1 and preventing it from displacing or tilting.

[0032] The movement of the sliding plug rod 293 will push the movable end of the first hydraulic device 31 to slide into the first hydraulic device 31. The sliding of the movable end of the first hydraulic device 31 will push the liquid on the inner wall of the first hydraulic device 31 into the inner wall of the second hydraulic device 32. The increase in the liquid in the inner wall of the second hydraulic device 32 will push the movable end of the second hydraulic device 32 to move away from the second hydraulic device 32. The movement of the movable end of the second hydraulic device 32 will push the sliding plug board 33 to move. The movement of the sliding plug board 33 will release the limit on the support board 34. Then the support board 34 will be driven by the fourth torsion spring to rotate towards the direction of the rotating shaft 5, strengthening the support strength between the rotating shaft 5 and the fixed plate 2. After the support between the fixed plate 2 and the rotating shaft 5 is enhanced, the influence of wind force on the structure can be effectively reduced, preventing the wind force from causing excessive relative displacement or deviation between the fixed plate 2 and the rotating shaft 5, thereby improving the stability of the overall structure. The rotation of the support board 34 will release the limit on the pull rod 35. Then the pull rod 35 will be pulled by the second spring. The pulling of the pull rod 35 will drive the insertion key 36 to move. The movement of the insertion key 36 will release the limit on the insertion block 38. When the limit on the insertion block 38 is released, the sliding sleeve 37 will be driven by the third spring to slide towards the side away from the support frame 11. The movement of the sliding sleeve 37 will drive the gear 12 to move. The movement of the gear 12 will release the limit on the rotating cover plate 192. Then the rotating cover plate 192 will be driven by the second torsion spring to seal the heat dissipation slot. Strong wind may cause unnecessary vibration or deviation of the photovoltaic panel 3. Especially when the heat dissipation slot is open, the wind force may cause unstable wind force to affect the photovoltaic module. Closing the heat dissipation slot can reduce the interference of wind force on the photovoltaic module, maintain the stability and direction of the module, and ensure that they can maintain the best working state.
