Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic supports, and in particular to a steel cable connection structure for a flexible photovoltaic support. Background Art

[0002] Flexible photovoltaic brackets are a commonly used photovoltaic support method. They have the characteristics of simple structure, low material consumption, light weight, and large span. They 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, the steel cables are very important. If photovoltaic panels can have a certain tilt angle during installation, it will greatly improve their ability to receive solar radiation in most areas and improve the efficiency of light energy reception. In existing flexible photovoltaic brackets, the steel cables are often set in 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 clear the snow, the weight of the photovoltaic panel will increase. This increased weight will put greater pressure on the steel cables supporting the photovoltaic panel, causing the steel cables to be over-tensioned, which may cause damage to the steel cables.

The lubricating oil flows into the groove through the oil outlet, and the sponge expands after absorbing the lubricating oil, and exerts pressure on the extrusion plate and the spring. As the sealing rod moves upward, it will close the oil outlet. At the same time, the lubricating oil inside the sponge is squeezed into the rolling groove through the oil filling port under pressure to provide lubrication for the balls.

The two mounting plates 402 are provided with a bent guide tube 403 between them. The middle of the two mounting plates 402 on the opposite side are fixedly connected with an adjustment plate 404. The two adjustment plates 404 are equidistantly provided with positioning openings 405. The left and right sides of the bent guide tube 403 are fixedly connected with a first connecting plate 406.

The plates 407 are respectively arranged on the front and rear sides of the two adjustment plates 404, and the two second connecting plates 407 are fixedly connected to the fixed shell 408 on the side away from the adjustment plate 404. The middle of the two fixed shells 408 is penetrated by a pull rod 409, and the rear ends of the two pull rods 409 are fixedly connected to the positioning blocks 412. Both sides of the two positioning blocks 412 are fixedly connected to the limiting protrusions 413. The surfaces of the two pull rods 409 located inside the fixed shell 408 are fixedly connected to the movable plates 410, and the surfaces of the two movable plates 410 are respectively connected to the inner walls of the two fixed shells 408. Sliding connection, the outside of the two pull rods 409 are each sleeved with a torsion spring 411, one end of the two torsion springs 411 are respectively fixedly connected to the inner wall of the two fixed shells 408, and the other end of the two torsion springs 411 are respectively fixedly connected to the surface of the two movable plates 410, and the inside of the bending guide tube 403 is evenly provided with rolling grooves 414, and the upper and lower sides of the rolling grooves 414 are rollingly connected with balls 415. 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 avoiding the influence of wear on the strength of the steel cable body 3.

[0034] 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 connection structures 4 are identically set. The two steel cable bodies 3 respectively pass through the two bending guide tubes 403, and the surfaces of the two steel cable bodies 3 are movably connected to the surfaces of the balls 415. 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. In this way, 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 tilt angle when installing, so that they can better receive solar radiation.

[0035] like Figure 6 、 Figure 7 As shown, the lubrication assembly 5 includes an oil storage box 501 arranged above the bending guide tube 403, and the bottom of the oil storage box 501 is fixedly connected with a connecting port 502, and the bottom end of the connecting port 502 is fixedly connected to the top of the bending guide tube 403, and an oil outlet 503 is provided in the middle of the bottom of the oil storage box 501, and 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. The bottom ends of the two springs 508 An extrusion plate 507 is provided, and the two 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 part of the top of the extrusion plate 507. 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 rolling groove 414 through the oil filling port 506 under pressure to provide lubrication for the ball 415.

[0036] like Figure 8 、 Figure 9As shown, the two groups of buffer components 6 include fixed boxes 601 arranged at the front, 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 interior of the fixed box 601, a counterweight block 603 is provided inside the fixed box 601, and guide rods 604 are passed through both sides of the counterweight block 603. 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. The two pull rings 605 The inner side of each is connected to a buffer spring 606, and the top ends of the two buffer springs 606 are fixedly connected to the bottom of the counterweight block 603. The internal structures of the two fixed boxes 601 are set in the same way. 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. 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, causing it to move upward, thereby increasing the extension length of the steel cable body 3 outside the fixed box 601 to relieve the tension of the steel cable body 3.

[0037] 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 position, thereby fixing the bending guide tube 403. 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 passing through these bending guide tubes 403. This design enables the photovoltaic panels to have a certain tilt angle when installing, 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 snowy days, 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-tensioned state. This over-tightened state may cause damage to the cable body 3, but when the counterweight block 603 is subjected to the force exerted by the cable body 3, it can stretch and compress the buffer spring 606, causing it to move upward, thereby increasing the extension length of the cable body 3 outside the fixed box 601 to relieve the tension of the cable body 3 and the thermal expansion and contraction of the cable body 3; through the action of the ball 415, the friction between the cable body 3 and the inner wall of the bending guide tube 403 can be effectively reduced, thereby preventing the cable body 3 from affecting its strength due to 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 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 rolling groove 414 through the oil filling port 506 under pressure, providing lubrication for the ball 415. After the lubricating oil inside the sponge 505 is completely discharged, the sponge 505 contracts to its initial state. The extrusion plate 507 drives the sealing rod 509 to move downward together under the action of the spring 508, and lubricating oil can continue to be added to the interior of the slot 504.

[0038] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
