Description

[0002] Flexible photovoltaic bracket is a commonly used photovoltaic support method at present. It has the characteristics of simple structure, less material use, light weight and large span. It can adapt to various working environments with high construction difficulty such as mountains, fish ponds and orchards. Since flexible photovoltaic brackets are supported by steel cables, steel cables are very important. When installing photovoltaic panels, if they can have a certain tilt angle, it will greatly improve their solar radiation receiving ability in most areas and improve the efficiency of light energy receiving. In existing flexible photovoltaic brackets, the setting of steel cables is often parallel. This design cannot effectively adjust the tilt angle when installing photovoltaic panels. At the same time, on snowy days in winter, when the top of the photovoltaic panel is covered with snow, if measures are not taken in time to remove the snow, the weight of the photovoltaic panel will increase.

Through the action of the balls 415, the friction between the steel cable body 3 and the inner wall of the bending guide tube 403 can be effectively reduced, thereby preventing the strength of the steel cable body 3 from being affected by wear.

[0022] like Figure 3 , Figure 5 , Figure 6As shown, the spacing between the two first connecting plates 406 and the adjusting plate 404 is smaller than the spacing between the two second connecting plates 407 and the adjusting plate 404, the inner diameter length of the y-axis of the positioning opening 405 is larger than the inner diameter length of the x-axis, the surfaces of the two positioning blocks 412 are slidably connected to the inner wall of the positioning opening 405, and the structures of the two sets of adjustable connecting structures 4 are set in the same manner.

The tops of the two bending guide tubes 403 and the inner walls of the tops of the bending guide tubes 403 are provided with lubrication components 5. The bending guide tubes 403 on both sides can be installed at different heights respectively, so that the two steel cable bodies 3 will form a certain height difference after penetrating these bending guide tubes 403. This design enables the photovoltaic panels to have a certain inclination angle when installing them, so that they can better receive solar radiation.

[0023] like Figure 6 , Figure 7 As shown, the lubrication assembly 5 includes an oil storage box 501 arranged above the bending guide tube 403, the bottom of the oil storage box 501 is fixedly connected with a connecting port 502, the bottom end of the connecting port 502 is fixedly connected to the top of the bending guide tube 403, an oil outlet 503 is provided in the middle of the bottom of the oil storage box 501, a groove 504 is provided on the inner wall of the top of the bending guide tube 403, a sponge 505 is provided inside the groove 504, and oil filling ports 506 are evenly provided at the bottom of the groove 504, the oil filling ports 506 and the rolling grooves 414 correspond to each other one by one, the grooves 504 are connected with the rolling grooves 414 through the oil filling ports 506, the bottom end of the connecting port 502 extends to the inside of the groove 504, and springs 508 are fixedly connected to both sides of the bottom of the oil storage box 501, and the bottom ends of the two springs 508 An extrusion plate 507 is provided, and both sides of the top of the extrusion plate 507 are fixedly connected to the bottom ends of the two springs 508 respectively. The extrusion plate 507 extends to the inside of the slot 504 through the connecting port 502 and contacts the surface of the sponge 505. A sealing rod 509 is fixedly connected to the middle of the top of the extrusion plate 507, and the top of the sealing rod 509 is tightly connected to the inner wall of the oil outlet 503. The lubricating oil flows into the inside of the slot 504 through the oil outlet 503. The sponge 505 expands after absorbing the lubricating oil and applies pressure to the extrusion plate 507 and the spring 508. As the sealing rod 509 moves upward, it will close the oil outlet 503. At the same time, the lubricating oil inside the sponge 505 is squeezed into the inside of the rolling groove 414 through the oil filling port 506 under pressure to provide lubrication for the ball 415.

[0024] like Figure 8 , Fig. 9As shown, the two groups of buffer components 6 include fixed boxes 601 arranged at the two front sides, the top of the fixed box 601 is fixedly connected to two guide wheels 602, one end of the steel cable body 3 passes through the middle of the two guide wheels 602 and extends to the inside of the fixed box 601, a counterweight block 603 is arranged inside the fixed box 601, and guide rods 604 are passed through both sides of the counterweight block 603, and the upper and lower ends of the two guide rods 604 are fixedly connected to the upper and lower inner walls of the fixed box 601 respectively, and the two sides of the bottom of the fixed box 601 are fixedly connected to pull rings 605, and the two pull rings 605 The inner side of each of the two boxes is connected to a buffer spring 606, the top ends of the two buffer springs 606 are fixedly connected to the bottom of the counterweight block 603, and the internal structures of the two fixed boxes 601 are configured identically. When snow accumulates on the top of the photovoltaic panel on a snowy day, the weight of the photovoltaic panel increases, which will exert greater pressure on the steel cable body 3 supporting the photovoltaic panel. When the counterweight block 603 is subjected to the force exerted by the steel cable body 3, it can stretch and compress the buffer spring 606 and move it upward, thereby increasing the extended length of the steel cable body 3 outside the fixed box 601 to relieve the tension of the steel cable body 3.

[0025] The working process of the present invention is as follows: when in use, the first connecting plate 406 and the second connecting plate 407 are sleeved on both sides of the adjustment plate 404, the pull rod 409 is pulled outward and rotated at the same time, the positioning block 412 and the limiting protrusion 413 are rotated to the vertical position in the natural state, the bending guide tube 403 is adjusted to a suitable height, the positioning block 412 and the limiting protrusion 413 are pushed and passed through the corresponding positioning opening 405, and then the force previously applied to the pull rod 409 is released. Under the action of the torsion spring 411, the positioning block 412 and the limiting protrusion 413 will rotate back to their initial positions, thereby fixing the bending guide tube 403. The bending guide tubes 403 on both sides can be installed at different heights respectively, so that after the two steel cable bodies 3 pass through these bending guide tubes 403, a certain height difference will be formed. This design enables the photovoltaic panels to have a certain inclination angle when installing the photovoltaic panels, so that they can better receive solar radiation, which can significantly improve the power generation efficiency of the photovoltaic power generation system; at the same time, when there is snow on the top of the photovoltaic panel on a snowy day, the weight of the photovoltaic panel increases, which will exert greater pressure on the steel cable body 3 supporting the photovoltaic panel, causing the steel cable body 3 to be in an over-tightened state, which This over-tightened state may cause damage to the steel cable body 3, but when the counterweight block 603 is subjected to the force exerted by the steel cable body 3, it can stretch and compress the buffer spring 606 to move it upward, thereby increasing the extension length of the steel cable body 3 outside the fixed box 601 to relieve the tight state of the steel cable body 3 and the thermal expansion and contraction of the steel cable body 3; through the action of the ball 415, the friction between the steel cable body 3 and the inner wall of the bending guide tube 403 can be effectively reduced, thereby preventing the strength of the steel cable body 3 from being affected by wear, and the lubricating oil flows into the oil outlet 503 through the oil outlet 503. Inside the slot 504, the sponge 505 expands after absorbing the lubricating oil and applies pressure to the squeezing plate 507 and the spring 508. As the sealing rod 509 moves upward, it closes the oil outlet 503. At the same time, the lubricating oil inside the sponge 505 is squeezed into the rolling groove 414 through the oil filling port 506 under pressure to provide lubrication for the ball 415. After the lubricating oil inside the sponge 505 is completely discharged, the sponge 505 shrinks to its initial state, and the squeezing plate 507 drives the sealing rod 509 to move downward under the action of the spring 508, and the lubricating oil can continue to be added to the inside of the slot 504.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
