Description

Technical Field

[0001] This utility model relates to the field of steel strand connection technology, specifically an anchor and steel strand connection structure. Background Technology

[0002] Flexible photovoltaic brackets are a new type of photovoltaic bracket. They are characterized by simple structure, less material usage, light weight, and large span, making them suitable for various environments such as mountains, fish ponds, and barren slopes. The space under the brackets can also serve as a simple indoor space for parking lots, clear water pools, etc.

[0003] With the widespread application of flexible photovoltaic support systems, especially in mountain photovoltaic systems using multi-span prestressed cable structures, the accumulated frictional force generated by cable sagging and anchorages often leads to wear on the cable surface, resulting in corrosion failure and affecting the safety of photovoltaic modules in the later stages.

[0004] For example, patent document CN 222509166 U discloses an anchor and steel strand connection structure, including two concrete bases, two uprights on one side of each concrete base, cement columns fixed to the bottom of the two concrete bases and the bottom of the two uprights, and a docking assembly fixed to the top of each upright. The docking assembly includes a docking frame. This utility model, by adding a flared opening to the docking sleeve, can minimize the friction between the cable and the edge of the docking sleeve, reduce friction in the actual working state of the cable, and ensure the safety of the assembly. During the factory processing of the docking sleeve, a docking sleeve with a flared opening is used. After on-site tensioning, the steel strand will swing up and down due to gravity and wind suction. Due to the flared opening design, the arc surface between the steel strand and the inner wall of the flared opening fits together, which can reduce the friction between the steel strand and the docking sleeve.

[0005] The existing technology can only achieve synchronous up-and-down swinging with a single direction. In addition, the anchor will be exposed after installation, and wear and tear on the connection between the anchor and the steel strand is unavoidable. Long-term exposure will also cause the worn surface to be exposed to rain and rust. Therefore, a new connection structure between the anchor and the steel strand is proposed to optimize the existing technology. Utility Model Content

[0006] The purpose of this utility model is to provide a connection structure between an anchor and a steel strand to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An anchor and steel strand connection structure includes a connection base, which comprises a steel frame. The top surface of the steel frame has two connection points, one high and one low. Each connection point is equipped with a connection component. Each connection component includes a fixing frame and an installation base. The fixing frame is fixedly installed to the steel frame by bolts. The installation base is a horizontally cylindrical structure fixedly connected to the fixing frame. One side of the installation base has a receiving cavity with an arc-shaped groove on its end face. The other side of the installation base has a bowl-shaped groove corresponding to and communicating with the arc-shaped groove. A hemispherical seat is movably connected within the arc-shaped groove. The spherical surface of the hemispherical seat slides in contact with the spherical surface of the arc-shaped groove. A portion of the hemispherical seat protrudes into the bowl-shaped groove, and a fixed connection is passed through the hemispherical seat. The assembly includes a connecting sleeve with a flared end fixedly connected to one end of the sleeve extending from the bowl-shaped groove. A sealing cap is threaded to the opening end of the mounting base corresponding to the receiving cavity. The sealing cap has internal threads on its inner side, and external threads on the outer wall of the mounting base corresponding to the opening end of the receiving cavity. By adding a flared end to the connecting sleeve, the friction between the cable and the edge of the connecting sleeve can be minimized, reducing friction during actual cable operation and ensuring component safety. With the connecting sleeve featuring a flared end, after on-site tensioning, the steel strand will swing up and down due to gravity and wind suction. The flared end design allows the arc surfaces between the steel strand and the inner wall of the flared end to fit together, reducing the friction between the steel strand and the connecting sleeve.

[0009] As a further embodiment of this utility model: a steel strand runs through the connecting sleeve, and the tail end of the steel strand extends into the receiving cavity and is connected to an anchor, which abuts against the hemispherical seat.

[0010] As a further embodiment of this utility model: the connecting foundation also includes two concrete foundations, each of which is fixedly connected with anchor bolts. The anchor bolts are pre-embedded parts. The steel structure frame is fixedly installed on the anchor bolts on one of the concrete foundations by nuts. The steel structure frame has round holes for the anchor bolts to pass through. On the other concrete foundation, two fixing seats are symmetrically fixedly installed on the anchor bolts by nuts. The fixing seats connected to the concrete foundation have round holes for the anchor bolts to pass through. The fixing seats are aligned with the two connection points on the steel structure frame. A fixing seat is also fixedly connected below the two connection points on the steel structure frame.

[0011] As a further embodiment of this utility model: each of the fixing seats is provided with a U-shaped buckle, and each end of the U-shaped buckle is connected to an end plate. The end plate has symmetrically arranged round holes for the U-shaped buckle to pass through. A diagonal threaded steel bar is connected through the end plates. The end plate has a centrally arranged round hole for the diagonal threaded steel bar to pass through.

[0012] As a further improvement of this utility model: the two ends of the U-shaped buckle are threaded with nuts after passing through the end plate, and the two ends of the U-shaped buckle are provided with external threads.

[0013] As a further improvement of this utility model: the two ends of the inclined threaded steel bar are threaded with nuts after passing through the corresponding end plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The anchor of this utility model rests against the hemispherical seat, and the steel strand passes through the connecting sleeve. Thus, when the steel strand swings due to wind and gravity, the hemispherical seat can form synchronous rotation and alignment in all directions (up, down, left, and right) within the arc groove. At the same time, the anchor is stored in the storage cavity and isolated by the sealing cover, thereby effectively avoiding the exposure of the anchor and the anchor connection position on the steel strand, and avoiding the situation of corrosion on the wear surface after rain.

[0016] 2. This utility model tensions the two end plates by locking the nuts at both ends of the inclined threaded steel bar, and achieves tension between the end plates and the fixed seat by locking the nuts at both ends of the U-shaped buckle, thereby providing a tension warning for the steel structure frame and providing stable anti-tipping capacity when the steel strand is tensioned.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3In this embodiment of the utility model, an anchor and steel strand connection structure includes a connecting base 1, which includes a steel frame 2. The top surface of the steel frame 2 has two connection points, one high and one low. Each connection point is provided with a connecting component 3. The connecting component 3 includes a fixing frame 4 and an installation base 5. The fixing frame 4 is fixedly installed to the steel frame 2 by bolts. The installation base 5 is a horizontally cylindrical structure and is fixedly connected to the fixing frame 4. One side of the installation base 5 has a receiving cavity 6, and the end face of the receiving cavity 6 has an arc-shaped groove 7. The other side of the installation base 5 has a bowl-shaped groove 8 that corresponds to and communicates with the arc-shaped groove 7. A hemispherical seat 9 that is adapted to the arc-shaped groove 7 is movably connected in the arc-shaped groove 7. The spherical surface of the hemispherical seat 9 slides in contact with the spherical surface of the arc-shaped groove 7. Part of the hemispherical seat 9 protrudes into the bowl-shaped groove 8. A through-hole fixed connection is provided on the hemispherical seat 9. The connecting sleeve 10 has a flared end 11 fixedly connected to one end of the connecting sleeve 10 extending out of the bowl-shaped groove 8. The mounting base 5 is threadedly connected to the opening end of the receiving cavity 6 with a sealing cap 12. The inner side of the sealing cap 12 is provided with internal threads, and the outer wall of the mounting base 5 is provided with external threads at the opening end of the receiving cavity 6. By adding a flared end 11 to the connecting sleeve 10, the friction between the cable and the edge of the connecting sleeve 10 can be reduced to the maximum extent, reducing friction in the actual working state of the cable and ensuring the safety of the component. With the connecting sleeve 10 in the form of a flared end 11, after the tensioning is completed on site, the steel strand 13 will swing up and down due to gravity and wind suction. Due to the design of the flared end 11, the arc surface between the steel strand 13 and the inner wall of the flared end 11 fits together to reduce the friction between the steel strand 13 and the connecting sleeve 10.

[0023] Anchor 14 rests against hemispherical seat 9, while steel strand 13 passes through connecting sleeve 10. Thus, when steel strand 13 sways due to wind and gravity, hemispherical seat 9 can achieve synchronous rotation and alignment in all directions (up, down, left, and right) within arc groove 7. Meanwhile, anchor 14 is housed in receiving cavity 6 and isolated by sealing cover 12, effectively preventing exposure of the connection position between anchor 14 and steel strand 13, and avoiding corrosion of the wear surface after rain.

[0024] A steel strand 13 runs through the connecting sleeve 10. The tail end of the steel strand 13 extends into the receiving cavity 6 and is connected to an anchor 14, which rests against the hemispherical seat 9.

[0025] The connecting foundation 1 also includes two concrete pile caps 15, each of which is fixedly connected with anchor bolts 16. The anchor bolts 16 are pre-embedded parts. The steel structure frame 2 is fixedly installed on the anchor bolts 16 on one of the concrete pile caps 15 by nuts. The steel structure frame 2 has a round hole for the anchor bolts 16 to pass through. On the other concrete pile cap 15, two fixing seats 17 are symmetrically fixedly installed on the anchor bolts 16 by nuts. The fixing seats 17 connected to the concrete pile cap 15 have a round hole for the anchor bolts 16 to pass through. The fixing seats 17 are aligned with the two connection points on the steel structure frame 2. A fixing seat 17 is also fixedly connected below the two connection points on the steel structure frame 2.

[0026] Each of the fixed bases 17 is provided with a U-shaped buckle 18, and each end of the U-shaped buckle 18 is connected to an end plate 19. The end plate 19 has symmetrically arranged round holes for the U-shaped buckle 18 to pass through. A diagonal threaded steel bar 20 is connected through the end plates 19. The end plate 19 has a centrally arranged round hole for the diagonal threaded steel bar 20 to pass through.

[0027] The two ends of the U-shaped buckle 18 pass through the end plate 19 and are threaded with nuts. The two ends of the U-shaped buckle 18 are provided with external threads.

[0028] The two ends of the inclined threaded steel bar 20 pass through the corresponding end plates 19 and are connected with nuts by threads.

[0029] Tensioning is achieved by locking the nuts at both ends of the inclined threaded steel bar 20 to the two end plates 19. Tensioning between the end plates 19 and the fixed seat 17 is achieved by locking the nuts at both ends of the U-shaped buckle 18, thereby giving the steel structure frame 2 a tension warning and providing stable anti-tipping capacity when the steel strand 13 is tensioned.

[0030] The working principle of this utility model is as follows:

[0031] In use, two separate fixing seats 17 are locked and fixed to the anchor bolts 16 on the corresponding concrete foundation 15 with nuts. The steel structure frame 2 is then fixed to the anchor bolts 16 on the corresponding concrete foundation 15 with nuts. U-shaped buckles 18 can be threaded onto both fixing seats 17 to further connect the upper end plate 19 and the inclined threaded steel bars 20. The nuts are then tightened, allowing the steel structure frame 2 to withstand the tension of the fixing seats 17. The fixing frame 4 of the connecting assembly 3 is then fixed to the steel structure frame 2 with bolts. The stranded wire 13 has a flared opening 11 that passes through the docking sleeve 10 and then extends to the rear side of the hemispherical seat 9. It then connects to the anchor 14 and is tensioned. At this time, the anchor 14 rests against the hemispherical seat 9. The sealing cap 12 is then screwed on, which seals the storage cavity 6. Thus, when the steel stranded wire 13 swings due to wind and gravity, the hemispherical seat 9 can form synchronous rotation and alignment in all directions (up, down, left, and right) within the arc groove 7. At the same time, the anchor 14 is stored in the storage cavity 6 and isolated by the sealing cap 12, thereby effectively preventing the anchor 14 and the connection position of the anchor 14 on the steel stranded wire 13 from being exposed.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
