[0015] The present invention provides a photovoltaic support for a solar power station. It has the following beneficial effects:

[0016] (1) In this invention, the push rod will move and contact the inclined surface of the sliding rod, then the push rod will push the sliding rod to slide upward, the sliding rod will move and drive the protrusion to move, the protrusion will lose contact with the groove, then the limit of the blocking rod will be released, then the blocking rod will be driven by the No. 1 spring to slide in the direction of the photovoltaic panel, strengthening the fixation of the installed photovoltaic panel. Strengthening the fixation between the photovoltaic panel and the fixing frame can ensure that the photovoltaic panel is more secure under various weather conditions, and avoid loosening or falling off of the photovoltaic panel under strong winds, heavy rains or other extreme weather conditions. (2) In this invention, the blocking rod will be driven by the No. 5 spring to slide in the direction away from the No. 1 elastic baffle, then the limit of the blocking rod on the No. 1 elastic baffle will be released, avoiding accidental triggering of the protection device when installing the photovoltaic panel. The premature activation of the protection device may cause delays in the installation progress. The staff needs to check and release the mistakenly triggered protection device before continuing to work, which may cause unnecessary downtime.

[0017] (3) In the present invention, when the short rod moves, the inclined surface of the short rod will contact the key, and the key will be pushed by the short rod to slide in the direction away from the push rod, and the limit of the push rod will be released, and the slot tube will be driven by the No. 4 spring to slide in the direction away from the motor, and the fixed frame will stop rotating, so as to avoid damage to the output end of the motor due to continued rotation when the fixed frame contacts an object. If the bracket hits a large object during rotation, the motor may be affected by overload or jamming, causing the motor to stop working or burn out. Excessive collision force may exceed the bearing capacity of the motor and even damage the driving part of the motor.

[0018] (4) In the present invention, when the rotating rod rotates in the direction away from the fixed frame, the inner rod will be pushed by the No. 6 spring to slide in the direction away from the rotating rod. The movement of the inner rod will drive the clamping plate to move. The movement of the clamping plate will contact the fixed frame. Then, the clamping plate will limit the fixed frame when the fixed frame stops rotating, so as to prevent the fixed frame from rotating rapidly in one direction. The sudden rapid rotation may cause the structure of the fixed frame and the photovoltaic panel to be impacted, which may cause damage or deformation of the fixed frame or the photovoltaic panel in the long run, thus affecting the service life of the equipment.

[0019] (5) In this invention, the movement of the pull plate will pull the fixed key to move away from the outer plate, and the limit of the outer plate will be released. The outer plate will be driven by the No. 3 torsion spring to rotate away from the support leg, and the inner plate will be pushed by the No. 8 spring to move away from the outer plate. The inner plate will contact the ground to strengthen the support for the support leg. During the rotation of the bracket, when it hits a larger object, if the bracket itself has strengthened support, its impact resistance will be significantly enhanced. This means that even if it encounters a strong external force, it can effectively absorb the impact energy to avoid damage or position displacement of the bracket and other components.

One end of the sliding plate 13 close to the square block 7 is fixedly installed on the movable end of the elastic telescopic rod 16. The slot tube 12 is slidably installed on the circumferential surface of the rotating shaft 5. The push rod 15 is fixedly installed on the side of the slot tube 12 close to the sliding plate 13. The key 14 is slidably installed on the side of the sliding plate 13 close to the push rod 15. A slot is provided on the side of the push rod 15 close to the key 14. The key 14 contacts the inner wall of the slot. When the convex block moves, it will lose contact with the groove, and the limit of the stop rod 10 will be released. Then, the stop rod 10 will be driven by the first spring to slide towards the photovoltaic panel, strengthening the fixation of the installed photovoltaic panel.

[0037] During the operation of this embodiment: When it is necessary to use the photovoltaic panel for electricity storage, the photovoltaic panel needs to be installed on the inner wall of the fixing frame 3. When installing the photovoltaic panel on the inner wall of the fixing frame 3, it will push the push plate 11 to slide towards the side close to the motor 2. The movement of the push plate 11 will push the push rod 8 to move. The movement of the push rod 8 will contact the inclined surface of the sliding rod 9, so the push rod 8 will push the sliding rod 9 to slide upward. The movement of the sliding rod 9 will drive the convex block to move, and the convex block will lose contact with the groove, so the limit of the blocking rod 10 will be released, and the blocking rod 10 will be driven by the first spring to slide towards the photovoltaic panel, strengthening the fixation of the installed photovoltaic panel. Strengthening the fixation between the photovoltaic panel and the fixing frame 3 can ensure that the photovoltaic panel is more firmly fixed under various weather conditions, avoiding loosening or falling off of the photovoltaic panel under strong winds, heavy rains or other extreme climate conditions. When the push plate 11 moves, it will push the movable end of the elastic telescopic rod 16 to move. The movement of the movable end of the elastic telescopic rod 16 will drive the sliding plate 13 to move. The movement of the sliding plate 13 will drive the key 14 to move. The movement of the key 14 will drive the push rod 15 to move. The movement of the push rod 15 will drive the groove tube 12 to slide towards the motor 2, so the inner wall of the chute of the groove tube 12 will contact the insert block at the output end of the motor 2. When the motor 2 rotates, it will drive the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 will drive the fixing frame 3 to rotate. The rotation of the fixing frame 3 will drive the photovoltaic panel to rotate, so that during the installation process of the photovoltaic panel, the fixing frame 3 is in a static state, and the photovoltaic panel will not be driven by the motor 2. This can avoid instability caused by the rotation or movement of the photovoltaic panel during the installation process, ensure the firm fixation of the photovoltaic panel during installation, and reduce the risk of accidents.

[0043] During the operation of this embodiment: When the photovoltaic panel is installed and the stop lever 10 moves to limit the photovoltaic panel, the contact between the blocking lever 295 and the stop lever 10 will be released. Then, the blocking lever 295 will be driven by the fifth spring to slide away from the first elastic baffle 20, and the limit of the blocking lever 295 on the first elastic baffle 20 will be released, avoiding accidentally touching the protection device during the installation of the photovoltaic panel, which may cause the premature activation of the protection device and delay the installation progress. The staff needs to check and release the accidentally triggered protection device before they can continue working, which may result in unnecessary downtime. When the motor 2 drives the fixed frame 3 to rotate, the fixed frame 3 may hit a relatively large object. When the rotating baffle 22 hits a relatively large object, the rotating baffle 22 will rotate towards the second elastic baffle 21. The rotation of the rotating baffle 22 will drive the fixed block 23 towards one end of the fixed baffle 24. Then, the fixed block 23 will contact the inclined surface of the fixed baffle 24, and the fixed block 23 will slide downward along the inclined surface of the fixed baffle 24. The downward movement of the fixed block 23 will drive the second elastic baffle 21 to move downward. The downward movement of the second elastic baffle 21 will push the sliding rod 25 to slide downward. The downward sliding of the sliding rod 25 will contact the inclined surface of the sliding block 26. Then, the sliding rod 25 will push the sliding block 26 to slide towards the sliding block 27. The sliding block 26 will contact the inclined surface of the sliding block 27. Then, the sliding block 26 will push the sliding block 27 to slide towards the key 14. The movement of the sliding block 27 will push the short rod 28 to move. When the short rod 28 moves, the inclined surface of the short rod 28 will contact the key 14. Then, the key 14 will be pushed by the short rod 28 to slide away from the push rod 15. The limit of the push rod 15 will be released. Then, the slot tube 12 will be driven by the fourth spring to slide away from the motor 2, and the fixed frame 3 will stop rotating, avoiding damage to the output end of the motor 2 when the fixed frame 3 continues to rotate after contacting an object. If the bracket hits a large object during rotation, the motor 2 may be affected by overload or jamming, resulting in the motor 2 stopping working or burning out. The excessive impact force may exceed the bearing capacity of the motor 2 and even damage the driving part of the motor 2. The sliding of the sliding block 27 will push the limit key 292 to move away from the rotating rod 29. The limit of the rotating rod 29 will be released. Then, the second torsion spring will drive the rotating rod 29 to rotate away from the fixed frame 3. When the rotating rod 29 rotates away from the fixed frame 3, the inner rod 291 will be pushed by the sixth spring to slide away from the rotating rod 29. The movement of the inner rod 291 will drive the clamping plate 293 to move. When the clamping plate 293 moves and contacts the fixed frame 294, the clamping plate 293 will limit the fixed frame 3 when the fixed frame 3 stops rotating, avoiding the fixed frame 3 rotating rapidly in one direction. The sudden rapid rotation may cause the structures of the fixed frame 3 and the photovoltaic panel to be impacted, which may lead to damage or deformation of the fixed frame 3 or the photovoltaic panel over time and affect the service life of the equipment.

[0044] When the clamping plate 293 rotates towards the fixed frame 294, it will contact the inclined surface of the sliding plate 30. Then, the clamping plate 293 will push the sliding plate 30 to slide towards the motor 2. The sliding of the sliding plate 30 will push the push plate 31 to move. The movement of the push plate 31 will drive the pressing plate 32 to move. The movement of the pressing plate 32 will contact the inclined surface of the vertical rod 33. Then, the pressing plate 32 will push the vertical rod 33 to slide downwards. The downward movement of the vertical rod 33 will push the pressing rod 34 to move downwards. The downward movement of the pressing rod 34 will contact the inclined surface of the pulling plate 35. Then, the pressing rod 34 will push one end of the pulling plate 35. The movement of the pulling plate 35 will pull the fixing key 36 to move away from the outer plate 37. Then, the limitation of the outer plate 37 will be released. Then, the outer plate 37 will be driven by the third torsion spring to rotate away from the support leg 1. Then, the inner plate 38 will be pushed by the eighth spring to move away from the outer plate 37. The inner plate 38 will contact the ground to strengthen the support for the support leg 1. During the rotation of the bracket, when hitting a larger object, if the bracket itself strengthens the support, its impact resistance will be significantly enhanced. This means that even when encountering a strong external force, it can effectively absorb the impact energy and avoid damage or position deviation of the bracket and other components. The movement of the sliding plate 30 will drive the sliding arc plate 39 to move. The movement of the sliding arc plate 39 will drive the push block 393 to move. The movement of the push block 393 will push the short plate 395 to move. The movement of the short plate 395 will drive the rotating key 394 to rotate. The rotation of the rotating key 394 will release the limitation on the insertion rod 392. When the limitation on the insertion rod 392 is released, the insertion rod 392 will be driven by the seventh spring to move towards the fixed frame 3. Then, the insertion rod 392 will contact the inner wall of the round opening. Then, the insertion rod 392 will strengthen the limitation on the fixed frame 3, can effectively reduce the continuous stress of the clamping plate 293, and avoid excessive fatigue damage of the clamping plate 293, making the fixed frame 3 and the protection device more durable.
