Description

Technical Field

[0001] The present invention relates to a photovoltaic mounting bracket, and more particularly to a photovoltaic bracket suitable for complex terrains. Background Art

[0002] Photovoltaic brackets originated in the 1970s when solar photovoltaic technology was still in its infancy. The earliest photovoltaic brackets were made of simple wood or metal materials to fix solar panels and orient them towards the sun. With the progress of solar photovoltaic technology, photovoltaic brackets have gradually developed into industrially produced products and use more durable and stable materials. In the 1980s, aluminum alloy began to be widely used in the manufacture of photovoltaic brackets and became the preferred material due to its light weight, corrosion resistance, and recyclability.

[0003] Currently, photovoltaic brackets have become an indispensable part of the construction of global photovoltaic power generation systems. Various types and specifications of photovoltaic brackets widely exist in the market, meeting the installation requirements of photovoltaic power generation in different sites and with different needs. However, the project sites of photovoltaic brackets are often located in places such as mountains, basins, and gobi deserts, where the terrain is often complex and various problems often occur during the installation process. Moreover, after the installation is completed, due to the fact that the installation sites of photovoltaic bracket projects are often located in harsh geographical environments such as mountains and basins, they are affected by external factors such as strong winds and snow, resulting in damage to the main body frame structure of the photovoltaic brackets.

[0004] After retrieval, the invention patent document with the publication number CN114362649A discloses a mountain photovoltaic bracket structure, including inclined rods, crossbars, ground piles, angle adjustment components, and height adjustment components; the ground piles are driven into the ground according to the depth required by the construction strength; the bottom surface of the crossbar is installed at the top of the ground pile through the height adjustment component, and the distance from the top of the ground pile is adjusted through the height adjustment component; the inclined rod is installed on the top surface of the crossbar through the angle adjustment component and is perpendicular to the crossbar; the crossbar is used to support the photovoltaic panel, and the slope of the crossbar itself is adjusted through the angle adjustment component.

[0005] The above-mentioned photovoltaic bracket includes several groups of symmetrically arranged height adjustment components. When adjusting the height of the photovoltaic bracket, it is necessary to adjust the height adjustment components on both sides separately. During the adjustment process, the height adjustment component on one side will hinder the adjustment of the height adjustment component on the side being adjusted, affecting the progress of height adjustment. Summary of the Invention

[0026] 4. In the present invention, the electric drive method can be replaced with a manual drive method for height adjustment, saving the installation and maintenance work of electrical equipment. And when rotating the manual wheel to drive the rotation of the rotating shaft, when the rotating shaft drives the worm to stop rotating, the worm wheel will also stop moving.

Specific embodiments

[0042] The following elaborates on the principles and spirit of the present invention in detail with reference to several representative embodiments of the present invention.

[0043] Embodiment 1:

[0044] Please refer to Figure 1 , a photovoltaic bracket suitable for complex terrains. A complete photovoltaic power generation site specifically has several photovoltaic brackets for installing photovoltaic panels. These photovoltaic brackets can be spliced and fixed. The photovoltaic bracket includes several spliced photovoltaic support plates 1, and the overall inclined surface of the installed photovoltaic bracket faces north-south, facilitating the photovoltaic panel components to perform photoelectric conversion.

[0045] Refer to Figure 2, at least four vertical rods 11 are symmetrically and fixedly installed on the lower surface of the photovoltaic support plate 1 by bolts. Below the vertical rods 11, a crossbar 12 is symmetrically and fixedly installed by bolts. Through the combined connection of the crossbar 12 and the vertical rods 11, several photovoltaic support plates 1 are assembled and spliced, enabling the installation of a relatively large number of photovoltaic panels.

[0046] Refer to Figure 2-4 , a support assembly 2 is symmetrically installed below each crossbar 12. An angle adjustment assembly 3 is also connected between the support assembly 2 and the crossbar 12. The support assembly 2 includes a first support rod 21, a second support rod 22, and a third support rod 23. The above-mentioned rods are all made of hollow steel pipes. And a stepped shaft is fixedly arranged at the lower end of the third support rod 23. The lower end rod of the stepped shaft slides within the second support rod 22, and the lower end rod of the second support rod 22 slides within the first support rod 21, facilitating height adjustment. At the same time, in cooperation with the angle adjustment assembly 3, the photovoltaic panels on the surface of the photovoltaic support plate 1 can better adapt to the harsh installation environment, ensuring efficient and stable light energy conversion work.

[0047] Refer to Figure 1-4 , in this embodiment, in order to further improve the support capacity of the photovoltaic bracket, a transverse telescopic support rod 16 can be symmetrically arranged between two correspondingly horizontally installed first support rods 21. The lower end of the transverse telescopic support rod 16 is fixed to the first support rod 21 through a buckle 17. The intersecting position at the upper ends of the two transverse telescopic support rods 16 is connected to the rigid connecting piece on the connecting shaft 15 by bolts. When installing the photovoltaic bracket, the upper ends of the two transverse telescopic support rods 16 can be hinged with the rigid connecting piece on the connecting shaft 15 to complete the installation of the photovoltaic bracket. When final fixation is required, the hinged state is changed to a tightened state by tightening the bolts.

[0048] Refer to Figure 1-4 , a vertical telescopic support rod 13 is symmetrically arranged between two correspondingly vertically installed first support rods 21. When installing the photovoltaic bracket, the lower end of the vertical telescopic support rod 13 is hinged to the buckle 17 fixed on the first support rod 21. At the same time, the intersecting position at the upper ends of the two vertical telescopic support rods 13 is hinged to the vertical rod 11 by bolts to complete the installation of the photovoltaic bracket. When final fixation is required, the hinged state is changed to a tightened state by tightening the bolts.

[0049] Specifically, both the transverse telescopic support rod 16 and the vertical telescopic support rod 13 are composed of two slidingly sleeved rods.

[0050] The angle adjustment assembly 3 includes a first connecting seat 31 and a second connecting seat 32.

[0051] Refer to Figure 5, the second connecting seat 32 is mainly composed of a connecting bottom plate 323, two triangular connecting plates 321 and two circular connecting plates 325. The two triangular connecting plates 321 are symmetrically and fixedly arranged on the lower surface of the connecting bottom plate 323, and the two circular connecting plates 325 are symmetrically and fixedly arranged on the upper surface of the connecting bottom plate 323. Moreover, the triangular connecting plates 321 and the circular connecting plates 325 are vertically arranged. A long strip stiffening plate 322 is fixedly arranged on the outer side surface of the triangular connecting plate 321, and the long strip stiffening plate 322 is fixed on the lower surface of the connecting bottom plate 323. A triangular stiffening plate 324 is fixedly arranged on the outer side surface of the circular connecting plate 325, and the triangular stiffening plate 324 is fixed on the upper surface of the connecting bottom plate 323.

[0052] Refer to Figure 5 , the triangular connecting plate 321 can be fixedly connected to the third support rod 23 through bolts and can be deflected before final fixation, thereby playing an adjusting role. The long strip stiffening plate 322 is welded to the triangular connecting plate 321 to fix the triangular connecting plate 321 and prevent it from deforming. The triangular stiffening plate 324 strengthens the connection strength of the circular connecting plate 325 and prevents the circular connecting plate 325 from deforming and being damaged due to excessive acting force in the east-west direction.

[0053] Refer to Figure 5 , the first connecting seat 31 is mainly composed of a top plate 313 and symmetrically arranged long strip connecting plates 311. A sliding block 312 is arranged on the outer side surface of the long strip connecting plate 311. The sliding block 312 can be used in cooperation with the circular connecting plate 325. Moreover, the components of the first connecting seat 31 are all fixedly connected together by welding. At the same time, the arc surface of the sliding block 312 is smooth and no welds are allowed to avoid situations where it is not easy to install and adjust due to the presence of welds.

[0054] Specifically, the first connecting seat 31 is fixedly fitted with the cross bar 12 through bolts, and the circular connecting plate 325 corresponds to the position of the sliding block 312. A connecting shaft 15 is arranged between two corresponding first connecting seats 31. Before the first connecting seat 31 is fixed to the cross bar 12, the two first connecting seats 31 and the second connecting seat 32 on both sides are connected together through the connecting shaft 15. And after the angles of the first connecting seat 31 and the second connecting seat 32 are adjusted, bolts and nuts can be used for fixation. After the fixation is completed, the angle between the third support rod 23 and the cross bar 12 can be adapted to the harsh terrain environment.

[0055] Refer to Figure 3-5, in this embodiment, due to the influence of the harsh environment, after the photovoltaic support is installed, it will be affected by wind and snow factors, causing damage to the main body frame of the photovoltaic support. Therefore, a first shock absorption assembly 4 can be installed between the second support rod 22 and the third support rod 23. This shock absorption assembly can effectively improve the wind and snow resistance of the main body of the photovoltaic support, effectively absorb and disperse the impact and vibration generated by external loads such as wind and snow on the photovoltaic support, improve the support effect of the main body of the support on the photovoltaic panel, and at the same time extend the service life of the support.

[0056] Refer to Figure 5 , the first shock absorption assembly 4 includes two groups of connection buckles 41. The two connection buckles 41 above are sleeved on the surface of the third support rod 23, and the two connection buckles 41 below are sleeved on the surface of the second support rod 22, and then fixed with bolts. Four groups of shock absorption assemblies are symmetrically arranged between the two corresponding connection buckles 41 up and down. Each group of shock absorption assemblies consists of two shock absorption rods 42 that are hinged at an angle. And the hinged positions of the two shock absorption rods 42 are connected by pins.

[0057] Refer to Figure 5 , convex blocks 411 are symmetrically and fixedly arranged on the outer surface of the connection buckle 41. The free ends of the convex blocks 411 and the corresponding shock absorption rods 42 are also hinged and matched by pins. Rubber blocks 421 are fixedly installed on the outer surfaces of the two shock absorption rods 42 that are at an angle. A first shock absorption spring 422 is fixedly connected between the two rubber blocks 421.

[0058] Refer to Figure 5 , a fourth shock absorption spring 232 is sleeved on the outer surface of the lower rod of the third support rod 23. Ring-shaped rubber bases four 231 are fixedly arranged on the upper and lower end faces of the fourth shock absorption spring 232. The upper rubber base four 231 is fixed on the end face of the lower stepped shaft of the third support rod 23, and the lower rubber base four 231 is fixed on the upper end face of the second support rod 22.

[0059] Specifically, both the rubber block 421 and the rubber base four 231 have good softness and plasticity. When subjected to vibration, the rubber molecular chains will deform, and the vibration energy will be absorbed by the friction energy consumption between molecules, thereby reducing the amplitude and frequency of vibration. Cooperating with the first shock absorption spring 422 and the fourth shock absorption spring 232 can effectively reduce the vibration influence of the wind on the photovoltaic support, thereby extending the service life of the photovoltaic support.

[0060] Furthermore, when the photovoltaic support plate 1 and the third support rod 23 are affected by wind force, the stepped shaft at the lower end of the third support rod 23 will slide within the second support rod 22. At the same time, the lateral wind force will also exert a lateral force on the first support rod 21, the second support rod 22, and the third support rod 23, causing the stepped shaft at the lower end of the third support rod 23 to slightly shake within the second support rod 22, which affects the service life of the third support rod 23 and the second support rod 22. At this time, the fourth damping spring 232 cooperates with the fourth rubber base 231 to slow down the vertical vibration. At the same time, the damping rods 42 around the third support rod 23 cooperate with the first damping spring 422 to slow down the vibration generated by the shaking, realizing the damping of the photovoltaic support, providing a more stable support for the photovoltaic panel, reducing the shaking and displacement caused by external factors, thereby improving the stability and power generation efficiency of the photovoltaic panel and also increasing the service life of the photovoltaic support.

[0061] Refer to Figure 3 , in this embodiment, it is necessary to fix the position of the bottom end of the first support rod 21. Due to the poor terrain environment in mountainous basins, it is necessary to pour a cubic cement base 6 in advance below the first support rod 21. The upper surface of the cement base 6 is in a horizontal state, which can ensure the installation stability of the photovoltaic support.

[0062] Refer to Figure 3 , a height adjustment assembly 5 is installed on the surface of the cement base 6. The height adjustment assembly 5 is used to adjust the height of the second support rod 22 so that the upper photovoltaic panel can perform photoelectric conversion in a suitable inclined state.

[0063] Refer to Figure 9 , symmetrically arranged installation grooves 61 are formed on the surface of the cement base 6. The installation grooves 61 can be adapted to the lower rod of the first support rod 21. After the first support rod 21 is inserted into the installation grooves 61, bolts and buckles 17 can be used to fix the first support rod 21 and the cement base 6.

[0064] Refer to Figure 4-9 , the height adjustment assembly 5 includes a rotating shaft 51 and symmetrically arranged T-shaped brackets 52.

[0065] The T-shaped bracket 52 is composed of a horizontal hollow steel pipe at the upper part and a vertical hollow steel pipe at the lower part welded together. The rotating shaft 51 passes through the hollow steel pipe at the upper end of the T-shaped support and is in rotational fit. Symmetrically arranged installation grooves 64 are formed on the surface of the cement base 6 at a position far from the installation grooves 61. The lower hollow steel pipe of the T-shaped bracket 52 is inserted into the installation grooves 64, and then bolts and buckles 17 are used to fix the T-shaped bracket 52 and the cement base 6.

[0066] Refer to Figure 4-8, a control box 53 is fixedly installed on the surface of the cement base 6 directly below the rotating shaft 51. Above the control box 53, a driving motor 531 that is used in cooperation with the control box 53 is installed. Both the control box 53 and the driving motor 531 are prior arts. Among them, the driving motor 531 has a self-locking function. On the surface of the output shaft of the driving motor 531, a first bevel gear 212 is fixedly arranged. On the middle surface of the rotating shaft 51, a second bevel gear 212 is fixedly arranged. The first bevel gear 212 and the second bevel gear 212 are meshed with each other. By driving the rotation of the first bevel gear 212 by the driving motor 531, the rotation of the second bevel gear 212 and the rotating shaft 51 is driven. And a protective cover can be installed on the cement base 6 to shield the positions of the control box 53, the driving motor 531, the first bevel gear 212, and the second bevel gear 212 to avoid the influence of external sand and wind.

[0067] Refer to Figure 4-8 , on one end surface of the horizontal hollow steel pipe above the T-shaped bracket 52, a threaded groove is opened, and a tightening nut 521 is threadedly arranged here. On the corresponding surface of the rotating shaft 51, a threaded groove is also opened, so that the tightening nut 521 can connect and fix the T-shaped bracket 52 and the rotating shaft 51, reducing the load transmitted to the driving motor 531 through the rotating shaft 51 when the lifting rod 24 supports the upper component and improving the service life of the driving motor 531.

[0068] Refer to Figure 4-8 , below the second support rod 22, a lifting rod 24 is fixedly arranged, and the lifting rod 24 also slides in the first support rod 21. The lifting rod 24 is composed of two vertically symmetrical circular connecting blocks, two vertical rods, and a rack 25, and the components inside the lifting rod 24 are all fixed together by welding.

[0069] Refer to Figure 4-8 , both ends of the rotating shaft 51 penetrate through the first support rods 21 on both sides, and on the surface of the rotating shaft 51 at the penetrating position, a bearing 512 is fixedly arranged. The bearing 512 is fixed to the first support rod 21 to ensure the rotational stability of the rotating shaft 51. At both ends of the rotating shaft 51, on the end faces located inside the first support rod 21, a worm 511 is fixedly arranged. The end of the worm 511 does not contact the rack 25. Above the worm 511, a rotating shaft 211 is arranged. The rotating shaft 211 is rotatably matched with the first support rod 21. On the middle surface of the rotating shaft 211, a worm gear 213 is fixedly arranged. The worm gear 213 does not contact the rack 25. The worm gear 213 is meshed with the worm 511, and on the surface of the rotating shaft 211 on both sides of the worm gear 213, gears 212 are symmetrically fixedly arranged. The gears 212 are meshed with the rack 25.

[0070] Specifically, the rotation of the rotating shaft 51 is driven by the driving motor 531, so that the worm 511 drives the rotation of the worm wheel 213, and then the gear 212 drives the lifting movement of the rack 25. Since the lead angle of the worm 511 is less than the equivalent friction angle between the meshing teeth, the worm wheel 213 and worm 511 mechanism has self-locking property. In this transmission structure, the worm 511 is used as the driving part. When the worm 511 stops rotating, the worm wheel 213 will also stop moving, which can further reduce the load borne by the driving motor 531.

[0071] Refer to Figure 9 , in this embodiment, in order to further improve the supporting effect on the lifting rod 24, mounting grooves two 63 and connecting grooves 62 can be symmetrically opened on both sides of the cement base 6. The mounting grooves two 63 communicate with the outside, and the connecting grooves 62 communicate the mounting grooves one 61 and the mounting grooves two 63. And a shock-absorbing support assembly 7 is arranged in the mounting grooves one 61, the connecting grooves 62 and the mounting grooves two 63.

[0072] Refer to Figure 9-10 , the shock-absorbing support assembly 7 includes a placement frame 71 and shock-absorbing springs two 741. An air pump 72 is fixedly installed in the placement frame 71. This air pump 72 is a prior art and can realize air intake and air release. And air holes communicating with the outside are opened on the closed plate surface of the placement frame 71 to ensure the normal use of the air pump 72.

[0073] Refer to Figure 9-10 , the shock-absorbing springs two 741 are arranged in the support rod one 21. And connecting pieces 743 and rubber bases one 74 are respectively fixedly arranged at the upper and lower ends of the shock-absorbing springs two 741. The rubber bases one 74 are arranged at the bottom of the mounting grooves one 61 and are fixed to the support rod one 21. The connecting piece 743 above is fixed to the bottom of the lifting rod 24. A spiral rubber sleeve 742 is sleeved outside the shock-absorbing springs two 741. The shock-absorbing springs two 741 can internally support the rubber sleeve 742. At the same time, the rubber sleeve 742 can extend up and down following the shock-absorbing springs two 741. And the upper and lower ends of the rubber sleeve 742 are respectively fixed to the connecting piece 743 and the rubber base one 74.

[0074] Refer to Figure 9-10 , an air pipe 73 is fixedly installed in the connecting groove 62. One end of this air pipe 73 is communicated with the output end of the air pump 72, and the other end penetrates through the rubber base one 74 and is communicated with the inside of the rubber sleeve 742.

[0075] Specifically, when the gear 212 rotates to drive the lifting rod 24 to rise, the air pump 72 and the air pipe 73 can be used to exhaust air from the rubber sleeve 742 to effectively support the lifting rod 24 above the connecting piece 743, reduce the wear between the rack 25 in the lifting rod 24 and the gear 212, improve the service life of the gear 212 and the rack 25, and when strong wind is encountered, the air pump 72 below inflates so that the air pressure in the rubber sleeve 742 can provide effective support for the upper lifting rod 24.

[0076] Further, when the external environmental factors cause vibration to the photovoltaic support, part of the vibration will be transmitted to the lifting rod 24 through the second support rod 22, and then transmitted from the lifting rod 24 to the second shock-absorbing spring 741, and then through the cooperation of the second shock-absorbing spring 741 and the first rubber base 74, the vibration is mitigated, and the stability and service life of the photovoltaic support are improved.

[0077] Embodiment 2:

[0078] Refer to Figure 11-14 On the basis of Embodiment 1, the components using electric drive in the height adjustment assembly 5 and the shock-absorbing support assembly 72 can be replaced, and the height adjustment is carried out manually, and at the same time, the lifting rod 24 is supported by hydraulic means.

[0079] Refer to Figure 11-14 Remove the control box 53, the drive motor 531, the first bevel gear 212 and the second bevel gear 212 in Embodiment 1, and then fixedly install a manual rotating wheel 54 on the middle surface of the rotating shaft 51.

[0080] Specifically, when the height needs to be adjusted, first screw the locking nut 521 to the outer side of the hollow steel pipe above the T-shaped bracket 52, and then manually rotate the manual rotating wheel 54 to make the two worms 511 drive the worm wheels 213 to rotate at the same time, so as to synchronously adjust the height of the two lifting rods 24. Since the lead angle of the worm 511 is less than the equivalent friction angle between the meshing teeth, the worm wheel 213 and the worm 511 mechanism has self-locking property. In this transmission structure, the worm 511 is used as the driving part. When the worm 511 stops rotating, the worm wheel 213 will also stop moving. Therefore, when the manual rotation stops, the rotating shaft 51 will also stop rotating, and the phenomenon that the lifting rod 24 continues to descend will not occur, improving the adjustment effect on the lifting rod 24.

[0081] Refer to Figure 11-14 Replace the placement frame 71, the air pump 72, the air pipe 73, the second shock-absorbing spring 741, the first rubber base 74, the connecting piece 743 and the rubber sleeve 742 in the second installation groove 63 in Embodiment 1 with an oil frame 75, a first oil inlet pipe 76, and an oil cylinder 78.

[0082] Refer to Figure 11-14 , the oil frame 75 is fixedly installed in the second installation groove 63, the first oil inlet pipe 76 is fixed in the connection groove 62 and communicates with the oil frame 75 at the same time, the oil cylinder 78 is fixed in the first support rod 21, and a drain pipe 786 communicating with the first oil inlet pipe 76 is fixedly arranged at the lower end of the oil cylinder 78.

[0083] Refer to Figure 11-14 , an L-shaped fixing plate 751 is fixedly arranged in the oil frame 75. The L-shaped fixing plate 751 divides the inner cavity of the oil frame 75 into two cavities for placing oil. The oil in the cavity near one end of the connection groove 62 is sufficient, and the oil in the other oil cavity does not fill the side oil cavity, and the volume of the oil cavity near the connection groove 62 is smaller than the volume of the outer oil cavity.

[0084] Refer to Figure 11-14 , a through hole communicating with the outside is opened on the surface of the outer closing plate of the oil frame 75. The maximum height of the oil in the side oil cavity is lower than the height of this through hole. This through hole can ensure the stable air pressure in the oil frame 75. An inverted U-shaped oil guide pipe 752 is fixedly arranged on the surface of the L-shaped fixing plate 751. The oil outlet openings at both ends of the oil guide pipe 752 are smaller, and the oil in the two side oil cavities can be converted.

[0085] Refer to Figure 11-14 , a piston rod 781 is slidably arranged in the oil cylinder 78. A rubber base three 785 is fixedly arranged on the upper end surface of the piston rod 781. The rubber base three 785 is fixed to the lower end of the lifting rod 24 to support the lifting rod 24.

[0086] Refer to Figure 11-14 , a cylinder 77 is fixedly arranged inside the first oil inlet pipe 76 near the oil frame 75. The cylinder 77 is provided with a T-shaped through hole 771 communicating with the oil frame 75 and the first oil inlet pipe 76. A spring five 772 is fixedly arranged on the outer end surface of the T-shaped through hole 771. A circular closing block 773 is fixedly arranged at the outer end of the spring five 772. The diameter of the circular closing block 773 is smaller than the inner diameter of the first oil inlet pipe 76, and the oil can pass through smoothly. When the spring five 772 reaches the compression limit, the closing block 773 can close one end of the T-shaped through hole 771, and at this time, the oil is prohibited from entering the inside of the oil frame 75.

[0087] Refer to Figure 11-14 , a first ejector rod 774 is fixedly arranged on the outer side surface of the closing block 773, a second ejector rod 782 is fixedly arranged on the lower end surface of the piston rod 781, and the second ejector rod 782 does not affect the oil from entering the first oil inlet pipe 76 from the oil cylinder 78. Both the first ejector rod 774 and the second ejector rod 782 are provided with inclined surfaces, and the second ejector rod 782 can drive the first ejector rod 774 by the downward movement of the piston rod 781 to push the closing block 773 to close the T-shaped through hole 771.

[0088] Refer to Figure 11-14 Figure 11-14 , a third shock-absorbing spring 784 is provided above the oil cylinder 78. The upper end of the third shock-absorbing spring 784 is fixed to the bottom end of the lifting rod 24, and a second rubber base 783 is fixedly arranged at the lower end, and the second rubber base 783 is fixed to the oil cylinder 78. When external environmental factors cause vibration to the photovoltaic bracket, part of the vibration will be transmitted to the lifting rod 24 through the second support rod 22, and then transmitted from the lifting rod 24 to the third shock-absorbing spring 784, and then through the cooperation of the third shock-absorbing spring 784 and the second rubber base 783, the vibration is slowed down, and the stability and service life of the photovoltaic bracket are improved.

[0089] Specifically, when the second support rod 22 is in the highest position, the third shock-absorbing spring 784 is in its original length at this time, and the oil in the two oil chambers is at the same horizontal plane. At this time, for the adjustment of the second support rod 22, it can only be lowered. As the second support rod 22 descends, it drives the lifting rod 24 to press down on the piston rod 781. At this time, the oil in the oil cylinder 78 enters the left oil chamber through the drain pipe 786 and the first inlet pipe 76, and then enters the right oil chamber through the U-shaped guide pipe 752. When rising again, the oil will fill the oil cylinder 78 through the U-shaped guide pipe 752.

[0090] Furthermore, when the wind pressure borne by the upper photovoltaic panel is too large, coupled with the daily wear of the gear 212 and the rack 25, after being subjected to an overload pressure, the meshing effect of the gear 212 and the rack 25 fails. At this time, the lifting rod 24 drives the piston rod 781 to move downward in a rapidly descending trend. However, at this time, due to the small inlet of the U-shaped guide pipe 752, the rapidly descending trend of the piston rod 781 will be blocked, so that its descending speed is slowed down. And when the second ejector rod 782 contacts the first ejector rod 774, it pushes the first ejector rod 774 to drive the closing block 773 into the T-shaped through hole 771. At this time, the piston rod 781 is still some distance from the inner bottom surface of the oil cylinder 78, and the piston rod 781 will not cause pressure on the bottom of the oil cylinder 78, avoiding damage to the oil cylinder 78 and the piston rod 781. After the closing block 773 closes the T-shaped through hole 771, the oil in the oil cylinder 78 cannot be discharged. At this time, a supporting force is provided for the piston rod 781 and the upper lifting rod 24 above. This anti-falling method can effectively reduce the losses suffered by the photovoltaic bracket after being affected by the wind.
