Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, specifically a photovoltaic support for a solar power plant. Background Technology

[0002] The global energy crisis has spurred the rapid development of the new energy industry, and solar energy is the most important basic energy among various renewable energy sources. Therefore, the photovoltaic industry, which converts solar radiation energy into electrical energy, has developed rapidly. In the old concept, the photovoltaic industry mainly includes the production chain of solar modules, and the production chain of electrical control components such as controllers and inverters.

[0003] Patent publication number CN118432509B relates to the field of photovoltaic support technology. It includes a support leg, a tripod rotatably mounted on the upper end of the support leg, and a photovoltaic panel receiving frame hinged to the left end of the tripod. A support controller is fixedly installed on the upper end of the tripod. By employing the aforementioned stabilizing sleeve, adaptive stabilizing assembly, and photovoltaic support control system, the stability and portability of the photovoltaic support installation are effectively improved, as well as its installation efficiency and automation. Furthermore, it effectively promotes the adaptability of the photovoltaic support to the installation environment, enhancing its versatility. It can be effectively applied to environments such as wastelands, plains, deserts, and large reservoirs, thereby reducing the construction cost of solar power plants, minimizing cost losses, effectively reducing the difficulty and cost of subsequent maintenance, promoting the reusability of the photovoltaic support, and effectively enhancing its economic adaptability.

[0004] The aforementioned patents effectively reduce the difficulty and cost of subsequent photovoltaic (PV) mounting system maintenance, promote the reuse rate of PV mounting systems, and effectively enhance the economic adaptability of PV mounting systems. However, during use, PV panels may become loose or fall off due to extreme weather conditions. Loosening or slipping of PV panels may cause them to fall directly or be impacted by external forces, resulting in damage. This will not only reduce the power generation efficiency of the system but may also cause irreparable losses and increase maintenance costs. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a photovoltaic support system for solar power plants, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a photovoltaic support for a solar power station, including a support leg and a fixing device, wherein a motor is fixedly installed on the right side of the support leg, the output end of the motor rotatably passes through the support leg, a support frame is fixedly installed on the side of the support leg away from the motor, a rotating shaft is slidably installed on the inner wall of the support frame, a fixing frame is fixedly installed on the circumferential surface of the rotating shaft, and a fixing plate is fixedly installed on the side of the fixing frame away from the support leg;

[0008] According to the above technical solution, the fixing device further includes a slot tube, a sliding plate, a locking key, and a push rod. A sliding groove is provided on the side of the support frame near the support leg. The sliding plate is slidably installed on the inner wall of the sliding groove. One end of the sliding plate near the square block is fixedly installed on the movable end of the elastic telescopic rod.

The locking key is slidably installed on the side of the sliding plate near the push rod. A locking groove is provided on the side of the push rod near the locking key. The locking key contacts the inner wall of the locking groove. When the protrusion moves, it loses contact with the groove, thus releasing the limit of the stop rod. The stop rod is then driven by the first spring to slide towards the photovoltaic panel, strengthening the fixing of the installed photovoltaic panel. Strengthening the fixing between the photovoltaic panel and the fixing frame ensures that the photovoltaic panel is more secure under various weather conditions, preventing loosening or detachment of the photovoltaic panel under strong winds, heavy rain, or other extreme weather conditions.

[0009] According to the above technical solution, the side of the push rod and the sliding rod that are close to each other is set as an inclined surface.

The blocking rod is slidably installed on the surface of the fixing plate. One end of the blocking rod contacts the stop bar, and the other end contacts the first elastic baffle. The limiting effect of the blocking rod on the first elastic baffle is released to prevent accidental activation of the protective device during photovoltaic panel installation.

The fixed frame is fixedly installed on the side of the support leg near the slot tube. When the inner rod moves, it will drive the clamping plate to move. When the clamping plate moves, it will contact the fixed frame. The clamping plate will limit the fixed frame when it stops rotating, preventing the fixed frame from rotating rapidly in one direction. Sudden rapid rotation may cause the structure of the fixed frame and photovoltaic panel to be impacted. Over time, this may cause damage or deformation to the fixed frame or photovoltaic panel, affecting the service life of the equipment.

[0012] According to the above technical solution, the side of the first elastic baffle and the second elastic baffle that are close to each other is set as an inclined surface.

The fixing key is slidably mounted on the side of the support leg near the outer plate. The pull plate is fixedly mounted on the side of the fixing key away from the motor. The sliding arc plate slides... The sliding arc plate is fixedly installed on the bottom of the sliding plate, the round rod is fixedly installed on the side of the support leg away from the motor, the insert rod is slidably installed on the inner wall of the round rod, the push block is fixedly installed on the top of the inner wall of the sliding arc plate, the rotating key is rotatably installed on the outer wall of the round rod, the short plate is fixedly installed on the top of the rotating key, the rotating key slides through the round rod, and the insert rod has a round hole on the side near the rotating key. The rotating key contacts the inside of the round hole, and the inner plate will contact the ground to strengthen the support for the support leg. When the bracket is rotating, if it hits a large object, if the bracket itself is reinforced, 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 and avoid damage or displacement of the bracket and other components.

[0014] According to the above technical solution, a No. 7 spring is provided between the round rod and the insert rod to drive the insert rod to move away from the round rod. A No. 8 spring is provided between the outer plate and the inner plate to drive the inner plate to move away from the outer plate. The side of the vertical rod near the pressure plate is set as an inclined plane to facilitate the pressure plate to press the vertical rod to move. The side of the pull plate and the pressure rod near each other is set as an inclined plane to facilitate the pressure rod to push the pull plate to move. A No. 3 torsion spring is provided between the outer plate and the support leg to drive the outer plate to rotate away from the support leg. A round opening is opened on the side of the fixing frame near the insert rod, and the shape of the insert rod matches the round opening.

[0015] This invention provides a photovoltaic (PV) mounting system for a solar power plant. It offers the following advantages:

[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 stop rod will be released, and the stop rod will be driven by the first spring to slide towards the photovoltaic panel, thereby 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 the photovoltaic panel from loosening or falling off under strong winds, rainstorms or other extreme weather conditions.

[0017] (2) In this invention, the blocking rod will be driven by the No. 5 spring to slide away from the No. 1 elastic baffle, and the limit of the blocking rod on the No. 1 elastic baffle will be released, so as to avoid accidentally touching the protection device when installing photovoltaic panels. Premature activation of the protection device may delay the installation progress. The staff needs to check and release the accidentally triggered protection device before they can continue to work, which may lead to unnecessary downtime.

[0018] (3) In this 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 away from the push rod. The limit of the push rod will be released, and the slot tube will be driven by the No. 4 spring to slide away from the motor. The fixed frame will stop rotating, so as to avoid damage to the output end of the motor when the fixed frame contacts an object. If the bracket hits a large object during rotation, the motor may be overloaded or jammed, causing the motor to stop working or burn out. Excessive collision force may exceed the motor's bearing capacity and even damage the motor's drive part.

[0019] (4) In this invention, when the rotating rod rotates away from the fixed frame, the inner rod will be pushed by the No. 6 spring to slide away from the rotating rod. The movement of the inner rod will drive the clamp to move. When the clamp moves, it will contact the fixed frame. The clamp will limit the fixed frame when the fixed frame stops rotating, preventing the fixed frame from rotating rapidly in one direction. Sudden rapid rotation may cause the structure of the fixed frame and photovoltaic panel to be impacted. Over time, this may cause damage or deformation to the fixed frame or photovoltaic panel, affecting the service life of the equipment.

[0020] (5) In this invention, 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. 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. When the bracket is rotated and hits a large object, if the bracket itself is strengthened, 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 and avoid damage or displacement of the bracket and other components.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-12 One embodiment of the present invention is: a photovoltaic support for a solar power station, including a support leg 1 and a fixing device. A motor 2 is fixedly installed on the right side of the support leg 1. The output end of the motor 2 rotates through the support leg 1. A support frame 4 is fixedly installed on the side of the support leg 1 away from the motor 2. A rotating shaft 5 is slidably installed on the inner wall of the support frame 4. A fixing frame 3 is fixedly installed on the circumferential surface of the rotating shaft 5. A fixing plate 6 is fixedly installed on the side of the fixing frame 3 away from the support leg 1.

[0036] The fixing device includes a square block 7, a push rod 8, a sliding rod 9, a stop rod 10, a push plate 11, and an elastic telescopic rod 16. The square block 7 is fixedly installed on the surface of the fixing plate 6. A groove is provided on the surface of the fixing plate 6. The push rod 8 is slidably installed on the inner wall of the groove. The sliding rod 9 is slidably installed on the inner wall of the square block 7. The stop rod 10 is slidably installed on the inner wall of the square block 7. The push plate 11 is slidably installed on the side of the fixing frame 3 near the square block 7. The elastic telescopic rod 16 is fixedly installed on the inner wall of the fixing frame 3. The push plate 11 is fixedly installed on the movable end of the elastic telescopic rod 16.

[0037] The fixing device also includes a slot tube 12, a sliding plate 13, a locking key 14, and a push rod 15. The support frame 4 has a sliding groove on the side near the support leg 1. The sliding plate 13 is slidably installed on the inner wall of the sliding groove. The end of the sliding plate 13 near 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 near the sliding plate 13. The locking key 14 is slidably installed on the side of the sliding plate 13 near the push rod 15. The push rod 15 has a slot on the side near the locking key 14. The locking key 14 contacts the inner wall of the slot. When the protrusion moves, it loses contact with the groove, and the limit of the stop rod 10 is released. The stop rod 10 is then driven by the first spring to slide towards the photovoltaic panel, strengthening the fixing of the installed photovoltaic panel. Strengthening the fixing between the photovoltaic panel and the fixing frame 3 can ensure that the photovoltaic panel is more secure under various weather conditions and prevent the photovoltaic panel from loosening or falling off under strong winds, heavy rain, or other extreme weather conditions.

[0038] The side of the push rod 8 and the sliding rod 9 that are close to each other is set as an inclined surface. This is to facilitate the push rod 8 to push the sliding rod 9 to move. A first spring is provided between the stop rod 10 and the fixed frame 3. The first spring is provided to drive the stop rod 10 back to its original position. A groove is provided at the bottom of the stop rod 10. A protrusion is fixedly installed on the top of the sliding rod 9. The protrusion contacts the inner wall of the groove. A second spring is provided between the sliding rod 9 and the fixed frame 3. The second spring is provided to drive the sliding rod 9 back to its original position. A third spring is provided between the key 14 and the sliding plate 13. The third spring is provided to drive the key 14 back to its original position. A plug is provided on the circumferential surface of the output end of the motor 2. A sliding groove is opened on the inner wall of the slot tube 12. The shape of the plug matches the sliding groove. A fourth spring is provided between the slot tube 12 and the rotating shaft 5. The fourth spring is provided to drive the slot tube 12 back to its original position.

[0039] In this embodiment, when the photovoltaic panel is to be used for energy storage, it needs to be installed on the inner wall of the mounting frame 3. When the photovoltaic panel is installed, the push plate 11 will slide towards the side closer to the motor 2. The movement of the push plate 11 will push the push rod 8 to move. The push rod 8 will then contact the inclined surface of the sliding rod 9, causing it to push the sliding rod 9 upwards. The movement of the sliding rod 9 will cause the protrusion to move. As the protrusion moves, it will lose contact with the groove, releasing the limit of the stop rod 10. The stop rod 10 will then 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 mounting frame 3 ensures that the photovoltaic panel is more secure under various weather conditions, preventing loosening or detachment under strong winds, heavy rain, or other extreme weather conditions. When plate 11 moves, it pushes the movable end of elastic telescopic rod 16 to move. The movement of the movable end of elastic telescopic rod 16 drives the sliding plate 13 to move. The movement of sliding plate 13 drives the locking key 14 to move. The movement of locking key 14 drives the push rod 15 to move. The movement of push rod 15 drives the slot tube 12 to slide towards the motor 2. Then the inner wall of the slot tube 12 will contact the plug 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 rotating shaft 5 will drive the fixing frame 3 to rotate. The rotation of fixing frame 3 will drive the photovoltaic panel to rotate. During the installation of the photovoltaic panel, the fixing frame 3 is in a stationary 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 that the photovoltaic panel is firmly fixed during installation, and reduce the risk of accidents.

[0040] Please see Figures 1-12 Based on the above embodiments, in another embodiment of the present invention, the surface of the fixing frame 3 is further provided with a protective device to prevent collision and a support device for reinforcing the support leg 1. The protective device includes a first elastic baffle 20, a second elastic baffle 21, a rotating baffle 22, a fixing block 23, a fixing baffle 24, and a blocking rod 295.

The fixed frame 3 is located on the side near the rotating shaft 5. The fixed baffle 24 is fixedly installed on the side of the rotating baffle 22 near the fixed block 23. The blocking rod 295 is slidably installed on the surface of the fixed plate 6. One end of the blocking rod 295 contacts the baffle 10, and the other end of the blocking rod 295 contacts the first elastic baffle 20.

Then, the clamping plate 293 will limit the fixed frame 3 when the fixed frame 3 stops rotating, so as to prevent the fixed frame 3 from rotating rapidly in one direction. Sudden rapid rotation may cause the structure of the fixed frame 3 and the photovoltaic panel to be impacted. Over time, it may cause damage or deformation of the fixed frame 3 or the photovoltaic panel, affecting the service life of the equipment.

The vertical rod 33 is slidably mounted on the side of the support leg 1 near the pressure plate 32. The pressure rod 34 is fixedly mounted on the bottom of the vertical rod 33. The outer plate 37 is rotatably mounted on the side of the support leg 1 near the vertical rod 33. The inner plate 38 is slidably mounted on the inner wall of the outer plate 37. The fixing key 36 is slidably mounted on the side of the support leg 1 near the outer plate 37. The pull plate 35 is fixedly mounted on the side of the fixing key 36 away from the motor 2. The arc plate 39 is slidably installed on the inner wall of the fixed frame 294. The sliding arc plate 39 is fixedly installed on the bottom of the sliding plate 30. The round rod 391 is fixedly installed on the side of the support leg 1 away from the motor 2. The insertion rod 392 is slidably installed on the inner wall of the round rod 391. The push block 393 is fixedly installed on the top of the inner wall of the sliding arc plate 39. The rotating key 394 is rotatably installed on the outer wall of the round rod 391. The short plate 395 is fixedly installed on the top of the rotating key 394. The rotating key 394 slides through the round rod 391. The insertion rod 392 has a round hole on the side near the rotating key 394. The rotating key 394 contacts the inside of the round hole. The inner plate 38 will contact the ground to strengthen the support for the support leg 1. When the bracket is rotating, if it hits a large object, if the bracket itself is reinforced, 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 and avoid damage or displacement of the bracket and other components.

[0044] A No. 7 spring is provided between the round rod 391 and the insertion rod 392. The No. 7 spring is provided to drive the insertion rod 392 to move away from the round rod 391. A No. 8 spring is provided between the outer plate 37 and the inner plate 38. The No. 8 spring is provided to drive the inner plate 38 to move away from the outer plate 37. The side of the vertical rod 33 closest to the pressure plate 32 is set as an inclined surface. The inclined surface on the side of the pull plate 35 and the pressure rod 34 closest to each other is set as an inclined surface. The inclined surface on the side of the pull plate 35 and the pressure rod 34 closest to each other is provided to facilitate the pressure rod 34 to push the pull plate 35 to move. A No. 3 torsion spring is provided between the outer plate 37 and the support leg 1. The No. 3 torsion spring is provided to drive the outer plate 37 to rotate away from the support leg 1. A round opening is opened on the side of the fixing frame 3 closest to the insertion rod 392. The shape of the insertion rod 392 matches the round opening.

[0045] In this embodiment, during operation: when the photovoltaic panel installation is complete 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. The blocking lever 295 will then be driven by spring number five to slide away from the first elastic baffle 20, thus releasing the limit of the blocking lever 295 on the first elastic baffle 20. This prevents accidental activation of the protection device during photovoltaic panel installation, as premature activation of the protection device could delay the installation progress. Workers would need to check and deactivate any falsely triggered protection devices before continuing work, potentially causing unnecessary downtime. When motor 2 drives the fixing frame 3 to rotate, the fixing frame 3 may collide with a large object. When the rotating baffle 22 collides with a large object, the rotating baffle 22... The rotating baffle 22 will rotate towards the direction of the second elastic baffle 21. The rotation of the baffle 22 will cause the fixed block 23 to move towards one end of the fixed baffle 24. The fixed block 23 will then contact the inclined surface of the fixed baffle 24 and slide downwards along the inclined surface of the fixed baffle 24. The downward movement of the fixed block 23 will cause the second elastic baffle 21 to move downwards. The downward movement of the second elastic baffle 21 will push the slide rod 25 downwards. The downward movement of the slide rod 25 will contact the inclined surface of the sliding block 26, which will then push the sliding block 26 towards the direction of the sliding block 27. The sliding block 26 will then contact the inclined surface of the sliding block 27, which will push the sliding block 27 towards the direction of the latch 14. The movement of the sliding block 27 will push the short... When lever 28 moves, the inclined surface of short lever 28 will contact key 14, pushing key 14 away from push rod 15. This releases the limit on push rod 15, causing slot tube 12 to slide away from motor 2, driven by spring number four. Fixture 3 will then stop rotating to prevent damage to the output of motor 2 if it continues to rotate while in contact with an object. If the bracket hits a large object during rotation, motor 2 may be overloaded or jammed, causing it to stop working or burn out. Excessive impact force may exceed motor 2's tolerance, even damaging the drive mechanism. Sliding block 27 will push limit key 292 away from the rotating area. When rod 29 moves in a certain direction, the limit of rotating rod 29 will be released. Then, the second torsion spring will drive rotating rod 29 to rotate away from the fixed frame 3. When rotating rod 29 rotates away from the fixed frame 3, inner rod 291 will be pushed by spring 6 to slide away from rotating rod 29. The movement of inner rod 291 will drive clamping plate 293 to move. When clamping plate 293 moves, it will contact fixed frame 294. Then clamping plate 293 will limit fixed frame 3 when fixed frame 3 stops rotating, to prevent fixed frame 3 from rotating rapidly in one direction. Sudden rapid rotation may cause the structure of fixed frame 3 and photovoltaic panel to be impacted. Over time, it may cause damage or deformation of fixed frame 3 or photovoltaic panel, affecting the service life of equipment.

[0046] When clamp 293 rotates toward fixed frame 294, it contacts the inclined surface of sliding plate 30. Clamp 293 then pushes sliding plate 30 to slide closer to motor 2. The sliding of sliding plate 30 pushes push plate 31 to move. Push plate 31 moves pressure plate 32 to move. Pressure plate 32 contacts the inclined surface of vertical rod 33, pushing vertical rod 33 downward. Vertical rod 33 moves downward, pushing pressure rod 34 downward. Pressure rod 34 contacts the inclined surface of pull plate 35, pushing one end of pull plate 35. Pull plate 35 moves and pulls fixed key 36 away from outer plate 37. The limit of outer plate 37 is released, and outer plate 37 is rotated away from support leg 1 by torsion spring No. 3. Inner plate 38 is pushed away from outer plate 37 by spring No. 8, and inner plate 38 contacts the ground to strengthen support for support leg 1. During the rotation of the frame, if it collides with a large object, its impact resistance will be significantly enhanced if the frame itself is reinforced. This means that even when encountering strong external forces, it can effectively absorb impact energy and prevent damage or displacement of the frame and other components. The movement of the sliding plate 30 will drive the sliding arc plate 39 to move, which in turn will drive the push block 393 to move. The movement of the push block 393 will push the short plate 395 to move, which will drive the rotating key 394 to rotate. The rotation of the rotating key 394 will release the limit on the insertion rod 392. Once the limit on the insertion rod 392 is released, the insertion rod 392 will be driven by the No. 7 spring to move towards the fixed frame 3. Then the insertion rod 392 will contact the inner wall of the circular opening, which will strengthen the limit on the fixed frame 3. This can effectively reduce the continuous stress on the clamping plate 293, prevent excessive fatigue damage to the clamping plate 293, and make the fixed frame 3 and the protective device more durable.
