Description

Technical Field

[0001] The invention relates to a photovoltaic mounting bracket, and in particular 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 point them toward the sun. With the advancement of solar photovoltaic technology, photovoltaic brackets gradually developed into industrially produced products and used more durable and stable materials. In the 1980s, aluminum alloys began to be widely used in the manufacture of photovoltaic brackets, becoming the preferred material due to its lightness, corrosion resistance and recyclability.

[0003] At present, photovoltaic brackets have become an indispensable part of the construction of photovoltaic power generation systems around the world. Photovoltaic brackets of various types and specifications are widely available in the market, meeting the photovoltaic power generation installation requirements of different sites and needs. However, photovoltaic bracket project sites are often located in mountainous areas, basins, Gobi deserts and other places. These places often have complex terrain conditions and various problems often occur during the installation process. After the installation is completed, since the photovoltaic bracket project installation site is often located in mountainous areas, basins and other harsh geographical environments, it will be affected by external factors such as strong winds and snow, causing the main frame structure of the photovoltaic bracket to be damaged by external forces.

[0004] After searching, the invention patent document with announcement number CN114362649A discloses a mountain photovoltaic bracket structure, including an inclined rod, a horizontal rod, a ground pile, an angle adjustment assembly and a height adjustment assembly; the ground pile is driven into the ground according to the depth required by the construction strength; the bottom surface of the horizontal rod is installed on the top of the ground pile through the height adjustment assembly, and the distance with the top of the ground pile is adjusted through the height adjustment assembly; the inclined rod is installed on the top surface of the horizontal rod through the angle adjustment assembly and is perpendicular to the horizontal rod; the horizontal rod is used to support the photovoltaic panel, and the horizontal rod adjusts its own slope through the angle adjustment assembly.

[0005] The above-mentioned photovoltaic bracket includes several groups of symmetrically arranged height adjustment components. When adjusting the height of the photovoltaic bracket, the height adjustment components on both sides need to be adjusted separately.

[0019] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0020] Embodiment 1: See also Figure 1 A photovoltaic bracket suitable for complex terrain. 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 photovoltaic support plates 1 spliced ​​together, and the overall inclined surface of the photovoltaic bracket after installation is north-south, which is convenient for photovoltaic panels to perform photoelectric conversion.

[0021] See also Figure 2 The lower surface of the photovoltaic support panel 1 is symmetrically fixed with no less than four vertical rods 11 by bolts, and the lower part of the vertical rods 11 is symmetrically fixed with cross rods 12 by bolts. Through the coordinated connection of the cross rods 12 and the vertical rods 11, several photovoltaic support panels 1 are combined and spliced, so that a larger number of photovoltaic panels can be installed.

[0022] See also Figure 2-4 A support assembly 2 is symmetrically installed under each cross bar 12, and an angle adjustment assembly 3 is also connected between the support assembly 2 and the cross bar 12. The support assembly 2 includes a support rod 1 21, a support rod 22 and a support rod 3 23. The above rods are all made of hollow steel pipes, and a stepped shaft is fixedly provided at the lower end of the support rod 3 23. The lower end rod of the stepped shaft slides in the support rod 22, and the lower end rod of the support rod 22 slides in the support rod 1 21, which is convenient for height adjustment. At the same time, the angle adjustment assembly 3 is used to enable the photovoltaic panels on the surface of the photovoltaic support panel 1 to better adapt to the harsh installation environment, so that it can ensure efficient and stable light energy conversion.

[0023] See also Figure 1-4 In this embodiment, in order to further improve the supporting capacity of the photovoltaic bracket, a transverse telescopic support rod 16 can be symmetrically arranged between two corresponding transversely installed support rods 21. The lower end of the transverse telescopic support rod 16 is fixed to the support rod 21 by a buckle 17, and the intersection of the upper ends of the transverse telescopic support rods 16 on both sides is connected to the rigid connecting piece on the connecting shaft 15 by bolts. When installing the photovoltaic bracket, the upper ends of the transverse telescopic support rods 16 on both sides 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 converted into a tightened state by tightening the bolts.

[0024] See also Figure 1-4A vertical telescopic support rod 13 is symmetrically arranged between two corresponding vertically installed 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 support rod 21. At the same time, the intersection of the upper ends of the two vertical telescopic support rods 13 is hinged to the vertical rod 11 through bolts to complete the installation of the photovoltaic bracket. When it needs to be finally fixed, the hinged state is changed to a fastened state by tightening the bolts.

[0025] Specifically, the transverse telescopic support rod 16 and the vertical telescopic support rod 13 are both composed of two slidably sleeved rods.

[0026] The angle adjustment assembly 3 includes a connection seat 1 31 and a connection seat 2 32. See also Figure 5 The connecting seat 2 32 is mainly composed of a connecting base plate 323, two triangular connecting plates 321 and two circular connecting plates 325. The two triangular connecting plates 321 are symmetrically fixed on the lower surface of the connecting base plate 323, and the two circular connecting plates 325 are symmetrically fixed on the upper surface of the connecting base plate 323, and the triangular connecting plates 321 and the circular connecting plates 325 are vertically arranged. The outer side surface of the triangular connecting plate 321 is fixedly provided with a long stiffening plate 322, and the long stiffening plate 322 is fixed on the lower surface of the connecting base plate 323. The outer side surface of the circular connecting plate 325 is fixedly provided with a triangular stiffening plate 324, and the triangular stiffening plate 324 is fixed on the upper surface of the connecting base plate 323.

[0027] See also Figure 5 The triangular connecting plate 321 can be fixedly connected to the support rod 323 by bolts, and can be deflected before being finally fixed, thereby playing an adjusting role. The long stiffening plate 322 is welded together with the triangular connecting plate 321 to fix the triangular connecting plate 321 to prevent its deformation. The triangular stiffening plate 324 strengthens the connection strength of the circular connecting plate 325 to prevent the circular connecting plate 325 from being deformed and damaged due to excessive force in the east-west direction.

[0028] See also Figure 5 The connecting seat 31 is mainly composed of a top plate 313 and a symmetrically arranged long connecting plate 311. A sliding block 312 is arranged on the outer side of the long connecting plate 311. The sliding block 312 can be used in conjunction with the circular connecting plate 325, and the components of the connecting seat 31 are fixed together by welding. At the same time, the arc surface of the sliding block 312 is smooth and no welds are allowed to avoid the situation where it is difficult to install and adjust due to the welds.

[0029] Specifically, the connecting seat 1 31 is fixedly matched with the cross bar 12 by bolts, and the circular connecting plate 325 will correspond to the position of the sliding block 312, and a connecting shaft 15 is arranged between the two corresponding connecting seats 1 31. Before the connecting seat 1 31 is fixed with the cross bar 12, the connecting seat 1 31 and the connecting seat 2 32 on both sides are connected together by the connecting shaft 15, and after the angle of the connecting seat 1 31 and the connecting seat 2 32 is adjusted, bolts and nuts can be used to fix them. After the fixing is completed, the angle between the support rod 3 23 and the cross bar 12 can adapt to the harsh terrain environment.

[0030] See also Figure 3-5 In this embodiment, due to the influence of the harsh environment, the photovoltaic bracket will be affected by wind and snow factors after installation, causing damage to the main frame of the photovoltaic bracket. Therefore, a first shock-absorbing assembly 4 can be installed between the support rod 22 and the support rod 3 23. The shock-absorbing assembly can effectively improve the wind and snow resistance of the photovoltaic bracket body, and can effectively absorb and disperse the impact and vibration of external loads such as wind and snow on the photovoltaic bracket, thereby improving the supporting effect of the bracket body on the photovoltaic panel and extending the service life of the bracket.

[0031] See also Figure 5 The first shock-absorbing assembly 4 includes two groups of connecting buckles 41. The upper two connecting buckles 41 are sleeved on the surface of the support rod three 23, and the lower two connecting buckles 41 are sleeved on the surface of the support rod two 22, and then fixed with bolts. Four groups of shock-absorbing assemblies are symmetrically arranged between the two corresponding upper and lower connecting buckles 41. Each group of shock-absorbing assemblies consists of two upper and lower shock-absorbing rods 42 that are hinged and angled, and the hinged positions of the two shock-absorbing rods 42 are connected by pins.

[0032] See also Figure 5 The outer surface of the connecting buckle 41 is symmetrically fixed with protrusions 411, and the protrusions 411 and the free ends of the corresponding shock-absorbing rods 42 are also hingedly matched through pins. A rubber block 421 is fixedly installed on the corresponding outer surfaces of the two shock-absorbing rods 42 at an included angle, and a shock-absorbing spring 422 is fixedly connected between the two rubber blocks 421.

[0033] See also Figure 5 A shock absorbing spring four 232 is sleeved on the outer surface of the lower end rod of the support rod three 23, and an annular rubber base four 231 is fixedly provided on the upper and lower end surfaces of the shock absorbing spring four 232. The upper rubber base four 231 is fixed on the end surface of the stepped shaft at the lower end of the support rod three 23, and the lower rubber base four 231 is fixed on the upper end surface of the support rod two 22.

[0034] Specifically, the rubber block 421 and the rubber base four 231 have good softness and plasticity. When vibrated, the rubber molecular chain will deform and absorb the vibration energy through friction energy dissipation between molecules, thereby reducing the amplitude and frequency of the vibration. Together with the shock-absorbing spring one 422 and the shock-absorbing spring four 232, the vibration impact of wind on the photovoltaic bracket can be effectively reduced, thereby increasing the service life of the photovoltaic bracket.

[0035] Furthermore, when the photovoltaic support panel 1 and the support rod three 23 are affected by wind, the stepped shaft at the lower end of the support rod three 23 will slide in the support rod two 22. At the same time, the lateral wind will also exert a lateral force on the support rod one 21, the support rod two 22 and the support rod three 23, causing the stepped shaft at the lower end of the support rod three 23 to shake slightly in the support rod two 22, affecting the service life of the support rod three 23 and the support rod two 22. At this time, the shock-absorbing spring four 232 cooperates with the rubber base four 231 to reduce the vertical vibration. At the same time, the shock-absorbing rod 42 around the support rod three 23 cooperates with the shock-absorbing spring one 422 to reduce the vibration caused by the shaking, thereby achieving shock absorption of the photovoltaic bracket, providing a more stable support for the photovoltaic panel, reducing shaking and displacement caused by external factors, thereby improving the stability and power generation efficiency of the photovoltaic panel and also improving the service life of the photovoltaic bracket.

[0036] See also Figure 3 In this embodiment, the bottom end of the support rod 21 needs to be fixed in position. Due to the poor terrain environment of the mountain basin, a cubic cement base 6 needs to be cast in advance under the 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 bracket.

[0037] See also Figure 3 A height adjustment component 5 is installed on the surface of the cement base 6, and the height adjustment component 5 is used to adjust the height of the support rod 22 so that the photovoltaic panel above can perform photoelectric conversion in a suitable tilt state.

[0038] See also Fig. 9 A mounting groove 61 is symmetrically provided on the surface of the cement base 6, and the mounting groove 61 can be matched with the lower end rod of the support rod 21. After the support rod 21 is inserted into the mounting groove 61, the support rod 21 and the cement base 6 can be fixed by using bolts and buckles 17.

[0039] See also Figure 4-9 The height adjustment assembly 5 includes a rotating shaft 51 and a symmetrically arranged T-shaped bracket 52. The T-shaped bracket 52 is composed of a horizontal hollow steel pipe on the top and a vertical hollow steel pipe on the bottom, and the rotating shaft 51 passes through the hollow steel pipe at the upper end of the T-shaped support and rotates together. A mounting groove three 64 is symmetrically opened on the surface of the cement base 6 away from the mounting groove one 61. The hollow steel pipe at the lower end of the T-shaped bracket 52 is inserted into the mounting groove three 64, and then the T-shaped bracket 52 is fixed to the cement base 6 using bolts and buckles 17.

[0040] See also Figure 4-8 A control box 53 is fixedly installed on the surface of the cement base 6 just below the rotating shaft 51, and a driving motor 531 used in conjunction with the control box 53 is installed above the control box 53. Both the control box 53 and the driving motor 531 are prior arts, wherein the driving motor 531 has a self-locking function, and a bevel gear 1 212 is fixedly provided on the surface of the output shaft of the driving motor 531, and a bevel gear 2 212 is fixedly provided on the middle surface of the rotating shaft 51, and the bevel gear 1 212 and the bevel gear 2 212 are meshed with each other, and the driving motor 531 drives the rotation of the bevel gear 1 212, thereby driving the rotation of the bevel gear 2 212 and the rotating shaft 51, and a protective cover can be installed on the cement base 6 to shield the control box 53 and the driving motor 531 as well as the positions of the bevel gear 1 212 and the bevel gear 2 212 to avoid the influence of external wind and sand.

[0041] See also Figure 4-8 A thread groove is provided on the surface of one end of the horizontal hollow steel pipe above the T-shaped bracket 52, and a tightening nut 521 is threadedly arranged here. A thread groove is also provided on the corresponding surface of the rotating shaft 51, so that the tightening nut 521 can connect and fix the T-shaped bracket 52 and the rotating shaft 51, thereby reducing the load transmitted to the driving motor 531 through the rotating shaft 51 when the lifting rod 24 supports the upper component, thereby improving the service life of the driving motor 531.

[0042] See also Figure 4-8 A lifting rod 24 is fixedly arranged below the support rod 22, and the lifting rod 24 also slides inside the support rod 1 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 fixed together by welding.

[0043] See also Figure 4-8, both ends of the rotating shaft 51 pass through the support rods 21 on both sides, and a bearing 512 is fixedly arranged on the surface of the rotating shaft 51 at the penetration position, and the bearing 512 is fixed to the support rod 21 to ensure the rotation stability of the rotating shaft 51, and a worm 511 is fixedly arranged on the end faces of the two ends of the rotating shaft 51 located inside the support rod 21, and the end of the worm 511 will not contact the rack 25, and a rotating shaft 211 is arranged above the worm 511, and the rotating shaft 211 is rotationally matched with the support rod 21, and a worm wheel 213 is fixedly arranged on the middle surface of the rotating shaft 211, and the worm wheel 213 will not contact the rack 25, and the worm wheel 213 is meshed with the worm 511, and gears 212 are symmetrically fixedly arranged on the surface of the rotating shaft 211 on both sides of the worm wheel 213, and the gear 212 is meshed with the rack 25.

[0044] 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 smaller than the equivalent friction angle between the meshing gear teeth, the worm wheel 213 and worm 511 mechanism has self-locking properties. In the transmission structure here, the worm 511 serves as a driving member. 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.

[0045] See also Fig. 9 In this embodiment, in order to further improve the supporting effect of the lifting rod 24, a second installation groove 63 and a connecting groove 62 can be symmetrically opened on both sides of the cement base 6, the second installation groove 63 is connected to the outside, the connecting groove 62 connects the first installation groove 61 and the second installation groove 63, and a shock-absorbing support component 7 is arranged in the first installation groove 61, the connecting groove 62 and the second installation groove 63.

[0046] See also Figure 9-10 The shock-absorbing support assembly 7 includes a placement frame 71 and a shock-absorbing spring 741. An air pump 72 is fixedly installed in the placement frame 71. The air pump 72 is a prior art that can realize air suction and air discharge. In addition, an air hole communicating with the outside world is opened on the surface of the closed plate of the placement frame 71 to ensure the normal use of the air pump 72.

[0047] See also Figure 9-10The shock absorbing spring 741 is arranged in the support rod 21, and the upper and lower ends of the shock absorbing spring 741 are respectively fixed with a connecting piece 743 and a rubber base 74, the rubber base 74 is arranged at the bottom of the mounting groove 61 and is fixed to the support rod 21, the upper connecting piece 743 is fixed to the bottom of the lifting rod 24, and a spiral rubber sleeve 742 is sleeved on the outer side of the shock absorbing spring 741, the shock absorbing spring 741 can provide internal support to the rubber sleeve 742, and the rubber sleeve 742 can extend up and down following the shock absorbing spring 741, and the upper and lower ends of the rubber sleeve 742 are respectively fixed to the connecting piece 743 and the rubber base 74.

[0048] See also Figure 9-10 An air pipe 73 is fixedly installed in the connecting groove 62 , one end of the air pipe 73 is connected to the output end of the air pump 72 , and the other end passes through the rubber base 74 and is connected to the inside of the rubber sleeve 742 .

[0049] Specifically, when the gear 212 rotates to drive the lifting rod 24 to rise, the air in the rubber sleeve 742 can be exhausted through the air pump 72 and the air pipe 73 to effectively support the lifting rod 24 above the connecting piece 743, thereby reducing the wear and consumption between the rack 25 in the lifting rod 24 and the gear 212, and improving the service life of the gear 212 and the rack 25. When encountering strong winds, the air pump 72 below inflates the air so that the air pressure in the rubber sleeve 742 can provide effective support for the lifting rod 24 above.

[0050] Furthermore, when external environmental factors cause vibration to the photovoltaic bracket, part of the vibration will be transmitted to the lifting rod 24 through the support rod 22, and then transmitted to the shock-absorbing spring 2 741 by the lifting rod 24. Then, the vibration is reduced by the coordinated use of the shock-absorbing spring 2 741 and the rubber base 1 74, thereby improving the stability and service life of the photovoltaic bracket.

[0051] Embodiment 2: See also Figure 11-14 On the basis of the first embodiment, the electrically driven components in the height adjustment assembly 5 and the shock absorbing support assembly 72 can be replaced, and the height adjustment can be performed manually, while the lifting rod 24 can be supported by hydraulic means.

[0052] See also Figure 11-14 , the control box 53 , the driving motor 531 , the bevel gear 212 1 and the bevel gear 212 2 in the first embodiment are removed, and then a manual rotating wheel 54 is fixedly installed on the middle surface of the rotating shaft 51 .

[0053] Specifically, when the height needs to be adjusted, the tightening nut 521 is first screwed to the outer side of the hollow steel pipe above the T-shaped bracket 52, and then the manual wheel 54 is manually rotated to make the worm 511 on both sides drive the worm wheel 213 to rotate at the same time, thereby making the lifting rods 24 on both sides perform synchronous height adjustment. Since the lead angle of the worm 511 is smaller than the equivalent friction angle between the meshing gear teeth, the worm wheel 213 and worm 511 mechanism are self-locking. In the transmission structure here, the worm 511 serves as a driving member. 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 lifting rod 24 will not continue to descend, thereby improving the adjustment effect of the lifting rod 24.

[0054] See also Figure 11-14 The placement frame 71, air pump 72, air pipe 73, shock absorbing spring 2 741, rubber base 1 74, connecting piece 743 and rubber sleeve 742 in the installation groove 2 63 in the first embodiment are replaced with an oil frame 75, an oil inlet pipe 1 76 and an oil cylinder 78.

[0055] See also Figure 11-14 The oil frame 75 is fixedly installed in the installation groove 2 63, the oil inlet pipe 1 76 is fixed in the connecting groove 62 and communicated with the oil frame 75, the oil cylinder 78 is fixed in the support rod 1 21, and an oil discharge pipe 786 communicated with the oil inlet pipe 1 76 is fixedly provided at the lower end of the oil cylinder 78.

[0056] See also Figure 11-14 An L-shaped fixing plate 751 is fixedly set in the oil frame 75, and 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 connecting groove 62 is sufficient, and the oil in the oil cavity on the other side does not fill the oil cavity on this side, and the volume of the oil cavity near one end of the connecting groove 62 is smaller than the volume of the oil cavity on the outside.

[0057] See also Figure 11-14 A through hole communicating with the outside world is opened on the surface of the external closing plate of the oil frame 75. The highest height of the oil in the oil chamber on this side is lower than the height of the through hole here. The through hole can ensure the stability of the air pressure in the oil frame 75. An inverted U-shaped oil guide pipe 752 is fixed on the surface of the L-shaped fixed plate 751. The oil outlets at both ends of the oil guide pipe 752 are small, which can realize the oil conversion in the oil chambers on both sides.

[0058] See also Figure 11-14 A piston rod 781 is slidably disposed in the oil cylinder 78 , and a rubber base 785 is fixedly disposed on the upper end surface of the piston rod 781 . The rubber base 785 is fixed to the lower end of the lifting rod 24 to support the lifting rod 24 .

[0059] See also Figure 11-14A cylinder 77 is fixedly set inside the oil inlet pipe 76 at one end close to the oil frame 75. The cylinder 77 is provided with a T-shaped through hole 771 which communicates with the oil frame 75 and the oil inlet pipe 76. A spring 5 772 is fixedly set on the outer end face of the T-shaped through hole 771. A circular closing block 773 is fixedly set on the outer end of the spring 5 772. The diameter of the circular closing block 773 is smaller than the inner diameter of the oil inlet pipe 76, so that the oil can pass through smoothly. When the spring 5 772 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 oil frame 75.

[0060] See also Figure 11-14 A push rod 1 774 is fixedly provided on the outer side surface of the closing block 773, and a push rod 2 782 is fixedly provided on the lower end surface of the piston rod 781. The push rod 2 782 will not affect the oil entering the oil inlet pipe 1 76 from the oil cylinder 78. Both the push rod 1 774 and the push rod 2 782 are provided with inclined surfaces, which can drive the push rod 2 782 to push the push rod 1 774 through the downward movement of the piston rod 781, so that the push rod 1 774 can push the closing block 773 to close the T-shaped through hole 771.

[0061] See also Figure 11-14 A shock-absorbing spring three 784 is arranged above the oil cylinder 78, and the upper end of the shock-absorbing spring three 784 is fixed to the bottom end of the lifting rod 24, and the lower end is fixedly provided with a rubber base two 783, and the rubber base two 783 is fixed to the oil cylinder 78. When external environmental factors cause vibration to the photovoltaic bracket, a part of the vibration will be transmitted to the lifting rod 24 through the support rod two 22, and then transmitted to the shock-absorbing spring three 784 by the lifting rod 24. Then, the vibration is reduced by the coordinated use of the shock-absorbing spring three 784 and the rubber base two 783, thereby improving the stability and service life of the photovoltaic bracket.

[0062] Specifically, when the support rod 22 is at the highest position, the shock absorber spring 3 784 is at its original length, and the oil in the oil chambers on both sides is at the same horizontal plane. At this time, the adjustment of the support rod 22 can only make it descend. As the support rod 22 descends, the lifting rod 24 drives the piston rod 781 to press down. At this time, the oil in the oil cylinder 78 passes through the oil drain pipe 786 and the oil inlet pipe 1 76 into the left oil chamber, and then enters the right oil chamber through the U-shaped oil guide pipe 752. When it rises again, the oil will fill the oil cylinder 78 through the U-shaped oil guide pipe 752.

[0063] Furthermore, when the wind pressure on the photovoltaic panel above is too great, coupled with the daily wear of the gear 212 and the rack 25, the meshing effect of the gear 212 and the rack 25 fails after being subjected to the overload pressure. At this time, the lifting rod 24 drives the piston rod 781 to move downward with a rapid downward trend. However, at this time, since the oil inlet of the U-shaped oil guide pipe 752 is small, the rapid downward trend of the piston rod 781 is blocked, and its downward speed is slowed down. When the second push rod 782 contacts the first push rod 774, the push rod 781 is pushed downward. A 774 drives the closing block 773 to enter the T-shaped through hole 771. At this time, the piston rod 781 is still some distance away 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, thereby 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 inside the oil cylinder 78 cannot be discharged. At this time, supporting force is provided for the piston rod 781 and the upper lifting rod 24. This anti-falling method can effectively reduce the losses suffered by the photovoltaic bracket after being affected by wind.
