Abstract

This invention relates to the field of solar photovoltaic panel support technology, and more particularly to a solar photovoltaic panel support bracket and its operating method. It includes a support base frame, a support platform rotatably connected to one side of the top of the support base frame, photovoltaic panels symmetrically installed inside the support platform, and a through-type sliding groove at the center of the top of the support platform. It also includes a retraction mechanism installed on the top of the support base frame. Through the retraction mechanism, when the wind-receiving panel is blown by strong winds, the wind-receiving panel drives the brake plate to move, thereby causing the guide groove to press against the sliding shaft. The first gear and the second rack mesh to drive the transmission. The pressing of the guide groove against the sliding shaft allows the clamping plate to no longer restrict the height of the top shaft.

Description

Technical Field

[0001] This invention relates to the field of solar photovoltaic panel support technology, and in particular to a solar photovoltaic panel support bracket and its operation method. Background Technology

[0002] With the rapid development of the new energy industry, solar photovoltaic panels are widely used due to their advantages of power generation and wide range of applications. As the core support structure that carries photovoltaic modules, the structural stability and environmental adaptability of photovoltaic power stations directly determine their service life, power generation stability and operation and maintenance safety.

[0003] To ensure the power generation efficiency of photovoltaic panels, they are mostly installed outdoors in open-air environments without any obstructions. This makes them highly susceptible to severe outdoor weather conditions. For example, in windy weather, since most photovoltaic panels are installed at an angle, their windward area is large and they are subjected to strong wind pressure, which can easily damage the panels and even cause the support frame to deform or the entire panel to tip over. Therefore, there is an urgent need for a photovoltaic panel support bracket that can automatically retract the photovoltaic panels and reduce the windward side in windy conditions. Summary of the Invention

[0008] Preferably, the shielding mechanism further includes a third rack, and L-shaped brackets are symmetrically fixed to the top of the support base. A commutator is fixed to the end of each of the two L-shaped brackets. The input end of the commutator rotatably passes through the L-shaped bracket and is fixed to a second gear.

Both rotating columns are rotatably connected to the support base through rotating seats.

[0009] Preferably, the system also includes a clamping mechanism. The clamping mechanism is installed inside the support base and includes a second T-shaped slider.

[0014] As a preferred embodiment, a method for operating a solar photovoltaic panel support bracket specifically includes the following steps: S1: In windy weather, the wind blows the wind-receiving plate to slide in the sliding groove. The wind-receiving plate pushes the brake plate to move through the push plate and the force block. The nitrogen spring extends and stores force. S2: Through the cooperation of the guide groove and the sliding shaft, the card plate is gradually pulled out from the top ring and the sliding cylinder, and through the meshing transmission of the first gear and the second rack, the top shaft is driven to rotate the support table downwards, so that the support table rotates to a horizontal state. S3: Under the meshing transmission of the third rack and the second gear, the rotating column will drive the shielding plate to rotate above the support platform, and through the cooperation of the pressing block and the elastic hydraulic telescopic component, the shielding plate can move downward and shield the photovoltaic panel. S4: When the strong wind ends, the brake plate moves in the opposite direction, the baffle plate and the top shaft move in the opposite direction to reset, and the support platform rotates back to the tilted state.

[0015] The beneficial effects of this invention are: 1. The present invention, through the setting of the retraction mechanism, enables the wind-receiving plate to drive the brake plate to move when the wind-receiving plate is blown by strong winds. This causes the guide groove to press against the sliding shaft, and the first gear and the second rack mesh to drive the transmission. The pressing of the guide groove against the sliding shaft enables the clamping plate to no longer restrict the height of the top shaft. The meshing transmission of the first gear and the second rack enables the top shaft to move downward, thereby driving the support platform and photovoltaic panel to rotate to a horizontal state, avoiding the situation where strong winds blow directly on the photovoltaic panel and thus damage the photovoltaic panel.

[0016] 2. By setting up a shielding mechanism, the present invention can drive the rotating column to rotate 90° through the meshing of the third rack and the second gear when the wind-receiving plate is blown by strong wind. Then, through the elastic release of the elastic hydraulic telescopic component, the shielding plate moves downward and shields the photovoltaic plate. In this way, the photovoltaic plate can be directly isolated from the strong wind, thereby protecting the photovoltaic plate. Attached Figure Description

Detailed Implementation

[0019] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Example 1

[0020] A solar photovoltaic panel support bracket, such as Figures 1-12As shown, the system includes a support base 1, a support platform 2 rotatably connected to one side of the top of the support base 1, photovoltaic panels 3 symmetrically installed inside the support platform 2, and a sliding groove 4 penetrating through the center of the top of the support platform 2. It also includes a retraction mechanism installed on the top of the support base 1, comprising a wind-receiving plate 5, which is slidably connected inside the sliding groove 4. Both ends of the wind-receiving plate 5 slide within the support platform 2. A hinge block 6 is fixedly connected to the bottom of the wind-receiving plate 5, and a push plate 7 is hinged inside the hinge block 6. The hinge block 6 can limit the rotation angle of the push plate 7. A sliding cylinder 14 is symmetrically fixed to the top of the support base 1, and nitrogen springs 8 are symmetrically installed via fixed seats. The nitrogen springs 8 consist of a cylinder, piston rod, high-pressure nitrogen, damping holes, and a spring. The nitrogen springs 8 can extend and store force normally, and retract and release force at a relatively slow speed. The retraction time of the nitrogen springs 8 can be controlled by adjusting the damping holes. The two nitrogen springs 8 are fixedly connected to the same brake plate 9 at their output ends. A force-bearing block 10 that can contact and cooperate with the push plate 7 is fixedly connected to the top of the brake plate 9. Guide grooves 11 are opened at both ends of the brake plate 9. The guide groove 11 consists of an inclined groove and a vertical groove. A sliding shaft 12 is slidably connected inside the guide groove 11. An L-shaped slide rail 101 is symmetrically opened at the top of the support base 1. The bottom of the two sliding shafts 12 is limited and slidably connected to the L-shaped slide rail 101. A card plate 13 that slides horizontally through the sliding cylinder 14 is fixedly connected to the top of the sliding shaft 12. A top shaft 15 is vertically slidably connected inside the sliding cylinder 14. A connecting joint 16 that is slidably connected to the bottom of the support platform 2 is fixedly connected to the top of the top shaft 15. The connecting joint 16 consists of two joints that are rotatably connected to each other. One joint is fixedly connected to the top shaft 15, and the other joint is slidably connected to the support platform 2.

[0021] The retracting mechanism also includes a top ring 17. The top ring 17, which is slidably connected to the bottom of the top shaft 15, is slidably connected inside the sliding cylinder 14. A locking plate 13 is slidably connected to the top ring 17 and can be locked into the top ring 17 to limit the position of the top shaft 15. A shaped rod 18 is fixedly connected to the bottom of the top ring 17. The shaped rod 18 is slidably connected to the sliding cylinder 14 and the support base 1. A first rack 19 is fixedly connected to the bottom of the shaped rod 18. A worm gear 20 is meshed on one side of the first rack 19. Inside the frame 1, two rotating bodies 21 are symmetrically fixed. The two rotating bodies 21 are rotatably connected to two worm gears 20 respectively. A worm 22 is meshed on one side of the worm gear 20. Both worms 22 are rotatably connected to the support base frame 1. The top of both worms 22 rotatably passes through the support base frame 1 and is fixedly connected to a first gear 23. The bottom of the brake plate 9 is symmetrically fixed with a second rack 24. The two second racks 24 are meshed with the two first gears 23 respectively. Both second racks 24 are slidably connected to the support base frame 1.

[0022] It also includes a shielding mechanism. The shielding mechanism is installed on the top of the support base 1. The shielding mechanism includes compression blocks 25 symmetrically fixed to the top of the brake plate 9. The support base 1 is fixed to an elastic hydraulic telescopic member 26 by two symmetrically arranged fixed frames. The elastic hydraulic telescopic member 26 is filled with hydraulic oil. Both sides of the output end of the elastic hydraulic telescopic member 26 are inclined. The end of the elastic hydraulic telescopic member 26 is fixedly connected to a conveying hose 27. One end of the conveying hose 27 is fixedly connected to a hydraulic telescopic plate 28. The telescopic end of the hydraulic telescopic plate 28 is fixedly connected to a shielding plate 29. The shielding plate 29 is in an elastic telescopic state. The top of one side of the support platform 2 and the top of the wind receiving plate 5 are symmetrically provided with grooves 201. The grooves 201 of the support platform 2 correspond to the grooves 201 of the wind receiving plate 5. The end of the shielding plate 29 can be inserted into the grooves 201 of the support platform 2 and the wind receiving plate 5 at the connection point with the hydraulic telescopic plate 28.

[0023] The shielding mechanism also includes a third rack 30. L-shaped brackets 31 are symmetrically fixed to the top of the support base 1. Commutators 32 are fixed to the ends of both L-shaped brackets 31. The input end of the commutator 32 rotatably passes through the L-shaped bracket 31 and is fixed to a second gear 33. The output end of the commutator 32 rotatably passes through the L-shaped bracket 31 and is fixed to a rotating column 34. Both rotating columns 34 are rotatably connected to the support base 1 through a rotating seat. A third rack 30 is symmetrically fixed to one side of the brake plate 9. The two third racks 30 mesh with the two second gears 33 respectively. The meshing transmission between the third racks 30 and the second gears 33 can only drive the commutator 32 to drive the rotating column 34 to rotate 90°.

[0024] It also includes a clamping mechanism. The clamping mechanism is installed inside the support base 1. The clamping mechanism includes a second T-shaped slider 38. A T-shaped groove 35 is opened on the top of the support base 1. A first T-shaped slider 36, which is fixed to the bottom of the brake plate 9, is slidably connected inside the T-shaped groove 35. A limit groove 37 is opened through the top of the support base 1. A second T-shaped slider 38 is slidably connected inside the limit groove 37.

[0025] The clamping mechanism also includes an elastic telescopic plate 3801. The bottom of the first T-shaped slider 36 has a slot 3601. The top of the second T-shaped slider 38 is rotatably connected to the elastic telescopic plate 3801. One side of the output end of the elastic telescopic plate 3801 is a slope. Both ends of the elastic telescopic plate 3801 are connected to the second T-shaped slider 38 by torsion springs.

[0026] The clamping mechanism also includes a first pull rope 39, and the first pull rope 39 is fixedly connected to one side of the second T-shaped slider 38. One end of the first pull rope 39 is fixedly connected to a sliding block 41 that is slidably connected to the support base 1. A first guide shaft 40 is wound around the outer wall of the first pull rope 39, and the first guide shaft 40 is rotatably connected to the support base 1.

[0027] The clamping mechanism also includes a second guide shaft 43. The second guide shaft 43 is rotatably connected to the side of the support base 1 away from the first guide shaft 40. Four second pull ropes 42 are wound on the second guide shaft 43. The second pull ropes 42 are slidably connected to the support base 1. One end of each of the four second pull ropes 42 is fixedly connected to the sliding block 41. The other end of each of the four second pull ropes 42 is slidably connected to the same fixing body 44. The fixing body 44 is fixedly connected to the support platform 2.

[0028] The clamping mechanism also includes wedge blocks 45. Four wedge blocks 45 are slidably connected inside the fixed body 44. The ends of the wedge blocks 45 are inclined. The four wedge blocks 45 are respectively fixed to the four second pull ropes 42. A compression spring 46 is fixed between the ends of the four wedge blocks 45 and the fixed body 44. The sum of the elastic forces of the torsion springs at both ends of the elastic telescopic plate 3801 is greater than the sum of the elastic forces of the four compression springs 46.

[0029] In the initial state, the support platform 2 and the photovoltaic panel 3 are tilted. The wind-receiving plate 5 is located at the end of the sliding groove 4 and does not block the photovoltaic panel 3. This allows the photovoltaic panel 3 to fully receive sunlight and generate electricity. The sliding shaft 12 is located at the end of the inclined groove of the guide groove 11. The clamping plate 13 is inserted into the top ring 17. The two ends of the clamping plate 13 are in contact with the sliding cylinder 14. The top surface of the clamping plate 13 is in contact with the bottom of the top shaft 15. The bottom surface of the clamping plate 13 is in contact with the top surface of the top ring 17. At this time, the top shaft 15 is restricted by the clamping plate 13 and cannot move downward. Thus, the two top shafts 15 support the support platform 2, making the support platform 2 tilted. Under good weather conditions, photovoltaic panel 3 will fully receive sunlight and generate electricity. However, in windy weather, the wind will blow directly onto photovoltaic panel 3 and wind-receiving plate 5, causing wind-receiving plate 5 to slide within sliding groove 4. Wind-receiving plate 5 slides upward along the tilt angle of support platform 2, and wind-receiving plate 5 will drive push plate 7 to slide synchronously via hinge block 6. When push plate 7 slides, it will contact force block 10. It should be noted that the elasticity of nitrogen spring 8 can be set to match that of photovoltaic panel 3. When the wind is not strong enough to damage photovoltaic panel 3, push plate 7 cannot drive brake plate 9 to move by pushing force block 10, and nitrogen spring 8 cannot extend. However, when the wind is strong enough to damage photovoltaic panel 3, push plate 7 can drive brake plate 9 to move by pushing force block 10. 10. When the brake plate 9 moves, the nitrogen spring 8 extends and stores force. When the brake plate 9 moves, the two second racks 24 move synchronously with the brake plate 9, and the guide groove 11 at the end of the brake plate 9 will squeeze the sliding shaft 12, causing the sliding shaft 12 to move along the inclined groove of the guide groove 11 and the L-shaped slide rail 101. Since the brake plate 9 is in a moving state at this time, when the guide groove 11 squeezes the sliding shaft 12, the sliding shaft 12 will be in a lateral movement state. The lateral movement of the sliding shaft 12 will drive the clamping plate 13 to move laterally, so that the clamping plate 13 is gradually pulled out from the sliding cylinder 14 and the top ring 17. It should be noted that the clamping plate 13 will be completely pulled out from the top ring 17, but not completely pulled out from the sliding cylinder 14. When the sliding shaft 12 moves to the guide groove 11, the sliding shaft 12 will move laterally. At the end of the vertical groove 1, the end of the clamping plate 13 away from the sliding shaft 12 will move to the inner edge of the sliding cylinder 14. At this time, the clamping plate 13 no longer supports the top shaft 15. At the same time, the second rack 24 meshes with the first gear 23. The brake plate 9 continues to move, and the sliding shaft 12 slides in the vertical groove of the guide groove 11. The sliding shaft 12 and the clamping plate 13 do not move. The sliding shaft 12 will gradually disengage from the vertical groove of the guide groove 11 during the movement of the brake plate 9. The sliding shaft 12 will not disengage from the L-shaped slide rail 101. The second rack 24 drives the first gear 23 to rotate. The first gear 23 drives the worm 22 to rotate. The worm 22 drives the worm wheel 20 to rotate. The worm wheel 20 drives the first rack 19 to move downward. The first rack 19 drives the shaped rod 18 downward. The irregularly shaped rod 18 moves downwards via the top ring 17, causing the top shaft 15 to move downwards. This downward movement of the top shaft 15, through the connecting joint 16, causes the support platform 2 to rotate, gradually bringing it to a horizontal position. The support platform 2 then rotates the photovoltaic panel 3 to a horizontal position. This directly prevents strong winds from blowing directly onto the photovoltaic panel 3, thus avoiding damage. It's important to note that the meshing between the worm gear 20 and the worm 22 has a self-locking property. When the clamping plate 13 no longer supports the top shaft 15, the top shaft 15 will not move downwards instantly due to strong winds, and the support platform 2 and photovoltaic panel 3 will not rotate instantly due to strong winds. Simultaneously, the meshing between the worm gear 20 and the worm 22 also reduces the transmitted force.This allows the first rack 19 and the top shaft 15 to move downwards at a slower speed. This also prevents the support platform 2 and the photovoltaic panel 3 from rotating instantly due to strong winds. If the support platform 2 and the photovoltaic panel 3 were to rotate instantly due to strong winds, and the clamping plate 13 no longer supports the top shaft 15, the support platform 2 would instantly rotate to a horizontal position, and the support platform 2 would collide violently with the support base 1. This collision would generate strong vibrations that could be transmitted to the photovoltaic panel 3, causing it to be damaged instantly. The worm gear 20 and worm 22 prevent this from happening. As the brake plate 9 moves, the pressing block 25 and the third rack 30 move synchronously with it. After the support platform 2 and the photovoltaic panel 3 rotate to a horizontal position, the brake plate 9 continues to move, the first gear 23 and the second rack 24 disengage, and the pressing block 25 contacts one of the inclined surfaces of the output end of the elastic hydraulic telescopic member 26. The brake plate 9 and the pressing block 25 continue to move, and the output end of the elastic hydraulic telescopic member 26 is compressed. The elastic hydraulic telescopic member 26 begins to contract and store force, and the hydraulic oil inside flows through the delivery hose 27 into the hydraulic telescopic plate 28, causing the hydraulic telescopic plate 28 to extend. The extension of the hydraulic telescopic plate 28 will drive the shielding plate 29 to move synchronously. At this time, the output end of the elastic hydraulic telescopic member 26 will always be in contact with the pressing block 25, thereby avoiding the elastic hydraulic... The telescopic member 26 is released elastically, the brake plate 9 and the pressing block 25 continue to move, the third rack 30 meshes with the second gear 33 and drives the second gear 33 to rotate. The rotation of the second gear 33 is transmitted to the commutator 32 and then to the rotating column 34, causing the rotating column 34 to rotate 90°. The rotating column 34 will drive the hydraulic telescopic plate 28 and the shielding plate 29 to rotate 90° synchronously. After the rotating column 34 rotates 90°, the hydraulic telescopic plate 28 rotates from a horizontal state to a vertical state, and the shielding plate 29 is located above the support platform 2 and the photovoltaic panel 3. The brake plate 9 and the pressing block 25 continue to move, the third rack 30 and the second gear 33 disengage, and then after the pressing block 25 moves a certain distance, the pressing block 25 disengages from the elastic hydraulic telescopic member 26. Upon contact, the elastic hydraulic telescopic component 26 releases elastically. At this time, the elastic hydraulic telescopic component 26 draws hydraulic oil from the inside of the hydraulic telescopic plate 28, causing the hydraulic telescopic plate 28 to begin to retract. Since the hydraulic telescopic plate 28 is in a vertical state at this time, the retraction of the hydraulic telescopic plate 28 will drive the baffle plate 29 to move downward. The baffle plate 29, moving downward, will contact and press against the inclined surfaces of the four wedge blocks 45, causing the wedge blocks 45 to retract into the fixed body 44. The compression spring 46 retracts, and the baffle plate 29 continues to move downward, passing over the wedge blocks 45. The compression spring 46 releases, causing the wedge blocks 45 to extend out of the fixed body 44. At this time, the four wedge blocks 45 can restrict the baffle plate 29, preventing the baffle plate 29 from moving upward. At this point, the elastic hydraulic telescopic component 26 has completed its release. The shielding plate 29 stops moving downwards, while the wind-receiving plate 5 has completed its movement and is now positioned at the other end of the sliding groove 4. The connection between the shielding plate 29 and the hydraulic telescopic plate 28 is inserted into the groove 201 of the support platform 2 and the wind-receiving plate 5. At this point, the two shielding plates 29 are shielding the two photovoltaic panels 3. The bottom of the shielding plate 29 contacts and engages with the support platform 2. One end of the shielding plate 29 is restricted by the wedge block 45, and the other end is restricted by the hydraulic telescopic plate 28 and contacts the wind-receiving plate 5. This prevents the photovoltaic panels 3 from directly contacting the strong winds, thus preventing damage. It is worth noting that the shielding plate 29 can be made of transparent material. When the shielding plate 29 is made of transparent material, it can both protect the photovoltaic panels 3 and provide additional protection.This also allows the photovoltaic panel 3 to continue generating electricity.

[0030] When the brake plate 9 slides, the first T-shaped slider 36 slides synchronously with the brake plate 9. The first T-shaped slider 36 slides within the T-shaped groove 35. During the sliding process of the first T-shaped slider 36, one bottom side of the first T-shaped slider 36 will contact the inclined surface of the output end of the elastic telescopic plate 3801. At this time, the baffle plate 29 begins to move downward. It should be noted that the frictional force between the second T-shaped slider 38 and the limiting groove 37 is less than the elastic force of the elastic telescopic plate 3801 itself. The sum of the elastic forces of the torsion springs at both ends of the elastic telescopic plate 3801 is greater than the elastic force of the elastic telescopic plate 3801 itself. Therefore, the movement of the first T-shaped slider 36 will push the elastic telescopic plate 3801 to move synchronously. The elastic telescopic plate 3801 drives the second T-shaped slider 38 to slide to the left within the limiting groove 37 (towards...). Figure 9(Using the direction reference), until the second T-shaped slider 38 slides to the left end of the limiting groove 37, at which point the second T-shaped slider 38 can no longer slide, while the first T-shaped slider 36 is still sliding. At this time, the inclined surface at the output end of the elastic telescopic plate 3801 will be compressed and contracted by the first T-shaped slider 36. Subsequently, the first T-shaped slider 36 continues to slide until the wind-receiving plate 5 slides to the end of the sliding groove 4. The wind-receiving plate 5 is located at the other end of the sliding groove 4, and the first T-shaped slider 36 no longer slides. At this time, the slot 3601 is located in the elastic telescopic... Above plate 3801, elastic telescopic plate 3801 is released elastically, and its output end extends into slot 3601. At the same time, shielding plate 29 has completed the shielding work of photovoltaic panel 3. It should be noted that in the above process, when the second T-shaped slider 38 slides to the left in the limiting groove 37, it will affect the position of wedge block 45. This may cause shielding plate 29 to not squeeze wedge block 45 when it moves downward, but this will not affect the effect of wedge block 45 extending from the fixed body 44 and limiting shielding plate 29. Once the strong winds subside and there's no longer any concern about damage to the photovoltaic panel 3, the nitrogen spring 8 begins to release its elasticity and contract. Due to the inherent characteristics of the nitrogen spring 8, its contraction is slow to prevent damage to the entire structure from excessively rapid contraction. During contraction, the nitrogen spring 8, via the brake plate 9, causes the force-bearing block 10 to move in the opposite direction. The brake plate 9 then causes its upper structure to move synchronously in the opposite direction. The force-bearing block 10, through the push plate 7 and hinge block 6, causes the wind-receiving plate 5 to move in the opposite direction. The wind-receiving plate 5 slides in the opposite direction within the sliding groove 4, pushing the baffle plate 29 to elastically contract. The baffle plate 29 stores force. When the brake plate 9 moves in the opposite direction, the first T-shaped slider 36 drives the elastic telescopic plate 3801 to move synchronously through the slot 3601. The second T-shaped slider 38 pulls the sliding block 41 through the first pull rope 39. Due to the setting of the first guide shaft 40, the second T-shaped slider 38 and the sliding block 41 move in opposite directions. The movement of the sliding block 41 will pull the wedge block 45 through the second pull rope 42. This causes the wedge block 45 to retract into the fixed body 44, and the compression spring 46 to contract. At this time, the wedge block 45 no longer restricts the baffle plate 29. Simultaneously, the pressing block 25 contacts another inclined surface at the output end of the elastic hydraulic telescopic member 26 and presses it, causing the elastic hydraulic telescopic member 26 to contract. The hydraulic oil inside it flows into the hydraulic telescopic plate 28 through the delivery hose 27. The output end of the hydraulic telescopic plate 28 extends and drives the baffle plate 29 to move upward. The upward movement of the baffle plate 29 will move it from the groove 201. When the baffle 29 moves upward past the fixed body 44 and no longer contacts the wind-receiving plate 5, the baffle 29 elastically releases. Simultaneously, the second T-shaped slider 38 moves to the other end of the limiting groove 37 and can no longer move. The first T-shaped slider 36 continues to move, pressing the elastic telescopic plate 3801 through the slot 3601, causing the elastic telescopic plate 3801 to rotate and the torsion spring to contract. Subsequently, the first T-shaped slider 36 passes over the elastic telescopic plate 3801, and the torsion spring releases.The elastic telescopic plate 3801 rotates to its reset position, and the compression spring 46 is released simultaneously. The wedge block 45 resets, and at the same time, the third rack 30 re-engages with the second gear 33, driving the second gear 33 to rotate in the opposite direction. The commutator 32 receives the force of the second gear 33's reverse rotation and outputs it to the rotating column 34, causing the rotating column 34 to rotate in the opposite direction. The rotating column 34 drives the hydraulic telescopic plate 28 and the baffle plate 29 to rotate 90° in the opposite direction to reset. Subsequently, the brake plate 9 continues to move, and the third rack 30 disengages from the second gear 33. The compression block 25 no longer compresses the elastic hydraulic telescopic component 26, causing the elastic hydraulic telescopic component 26 to release elastically, drawing hydraulic oil from the hydraulic telescopic plate 28, causing the hydraulic telescopic plate 28 to contract. The brake plate 9 continues to move, and the sliding shaft 12 inserts into the vertical groove of the guide groove 11 and slides within the vertical groove. During this process, the first gear 23 re-meshes with the second rack 24, and the second rack 24 drives the first gear 23 to rotate in the opposite direction. The first gear 23 drives the worm 22 to rotate in the opposite direction, and the worm 22 drives the first rack 19 to rotate in the opposite direction through the worm wheel 20. The first rack 19 moves upward, driving the top shaft 15 upward via the shaped rod 18 and the top ring 17. The top shaft 15, through the connecting joint 16, drives the support platform 2 and the photovoltaic panel 3 to rotate upward, causing the support platform 2 and the photovoltaic panel 3 to rotate from a horizontal state to an inclined state. When the sliding shaft 12 slides to the end of the vertical groove, the first gear 23 disengages from the second rack 24. Through the self-locking property of the worm gear 20 and the worm 22, the position of the top shaft 15 is locked. Subsequently, the inclined groove of the guide groove 11 compresses the sliding shaft 12 to move laterally. Shaft 12 drives the clamping plate 13 to move towards the inside of the sliding cylinder 14. Finally, when the sliding shaft 12 slides to the end of the inclined groove of the guide groove 11, which is the initial position, the clamping plate 13 re-inserts into the sliding cylinder 14 and the top ring 17, restricting the top shaft 15. At this time, the nitrogen spring 8 has completed its retraction, and the support platform 2 and photovoltaic panel 3 are also in an inclined state. The wind-receiving plate 5 can slide in the reverse direction within the sliding groove 4 under its own weight until the wind-receiving plate 5 drives the hinge block 6 and the push plate 7 to move back to the initial state. At this point, the reset process is complete. Example 2

[0031] A method for operating a solar photovoltaic panel support bracket, the method specifically includes the following steps: S1: In windy weather, the wind blows the wind-receiving plate 5 to slide in the sliding groove 4. The wind-receiving plate 5 pushes the brake plate 9 to move through the push plate 7 and the force block 10, and the nitrogen spring 8 extends to store force. S2: Through the cooperation of the guide groove 11 and the sliding shaft 12, the clamping plate 13 is gradually pulled out from the top ring 17 and the sliding cylinder 14, and through the meshing transmission of the first gear 23 and the second rack 24, the top shaft 15 is driven to rotate the support platform 2 downward, so that the support platform 2 rotates to a horizontal state. S3: Under the meshing transmission of the third rack 30 and the second gear 33, the rotating column 34 will drive the shielding plate 29 to rotate above the support platform 2, and through the cooperation of the pressing block 25 and the elastic hydraulic telescopic member 26, the shielding plate 29 can move downward and shield the photovoltaic panel 3. S4: When the strong wind ends, the brake plate 9 moves in the opposite direction, the baffle plate 29 and the top shaft 15 move in the opposite direction to reset, and the support platform 2 rotates back to the tilted state.
