Description

Technical Field

[0001] The utility model relates to the technical field of anchoring of photovoltaic cables, in particular to a special anchor for photovoltaic main cables. Background Art

[0002] Photovoltaic brackets are structures used to support solar panels in solar photovoltaic power generation systems. With the further development of solar photovoltaic power generation technology, photovoltaic power generation projects in complex environments such as mountains, water surfaces, Gobi, deserts, and bays have gradually been carried out. In terms of the selection of photovoltaic brackets, rigid brackets are difficult to apply to complex geographical conditions due to their limitations such as non-adjustability after fixation, poor wind resistance and weak corrosion resistance. The flexible prestressed bracket using steel stranded cables has the advantages of better improving the support method of photovoltaic power generation systems with large spans, high environmental space utilization, and low cost, and has been increasingly used in projects in complex terrain areas. Generally, the double anchoring of photovoltaic anchor products on the market is to add a support structure between the anchor anti-loosening cover and the extrusion sleeve, and then adjust and lock the support structure after the extrusion is completed, which plays a role of mutual tightening. It is necessary to first install the support structure and adjust it to the minimum distance, and then use a special extrusion equipment to extrude it. After the extrusion is completed, adjust the support structure to the tightening position. The construction is relatively cumbersome and requires relatively high requirements for construction workers. Utility Model Content

[0003] The utility model aims to provide a special anchor for photovoltaic main cables, which can solve the problem that the double anchoring construction of existing photovoltaic anchor products is relatively cumbersome and has relatively high requirements on construction workers.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: this special anchor for photovoltaic main cables includes a steel strand, one end of which is connected to a bracket, and the other end of the steel strand is equipped with a photovoltaic anchor, the front end of the photovoltaic anchor is crimped with one side of the bracket, and a clip wrapped around the steel strand is squeezed inside the photovoltaic anchor, an anti-loosening cover is provided on the rear end of the photovoltaic anchor, a steel strand connector is sleeved on the steel strand segment extending out of the anti-loosening cover, the outer wall of the rear section of the steel strand connector is provided with an external thread, and the anti-loosening cover of the photovoltaic anchor is screwed on the rear section of the steel strand connector; a photovoltaic anchor support sleeve is sleeved on the steel strand segment between the anti-loosening cover of the photovoltaic anchor and the anti-loosening cover.

[0005] In the technical solution of the above-mentioned special anchor for photovoltaic main cables, a more specific technical solution may also be: the steel strand connector is a columnar body, and a long through hole adapted to the steel strand is provided in the columnar body.

[0006] Furthermore, the anti-loosening cover is provided with an internal thread therein, and the photovoltaic anchor has an external thread thereouter corresponding to the internal thread of the anti-loosening cover, and the anti-loosening cover is threadedly connected to the photovoltaic anchor.

[0007] Furthermore, the rear section of the photovoltaic anchor support sleeve is crimped onto the outer wall of the steel strand connector, the rear end thereof abuts against the front end of the photovoltaic anchor anti-loosening cover, and the front end thereof abuts against the cover plate of the anti-loosening cover.

[0008] Furthermore, the vertical rod of the bracket is provided with a through hole that penetrates the bracket transversely, and the side of the bracket plate of the bracket is provided with a through hole corresponding to the through hole of the vertical rod, and the steel strand passes through the two through holes.

[0009] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0010] 1. This special anchor for photovoltaic main cable is installed after extrusion, and then the photovoltaic anchor support sleeve and photovoltaic anchor anti-loosening cover are installed for tightening. The construction is convenient and fast, and does not require complicated construction technology.

[0011] 2. A steel strand connector is installed behind the photovoltaic anchor. The steel strand connector is cold-extruded on the steel strand. After extrusion, it forms a whole with the steel strand, and then cooperates with the photovoltaic anchor support sleeve and the photovoltaic anchor anti-loosening cover to form a secondary locking protection. When the front-end photovoltaic anchor clip fails for some reason, it will not cause the steel strand to fall off and cause a collapse accident due to the slippage of the main cable.

[0012] 3. This photovoltaic main cable special anchor can completely seal the clip and the steel strand without adding a protective cover device. It only needs to fill grease between the special anchor and the steel strand to make the clip, steel strand connector and steel strand anchor end rainproof, dustproof and anti-oxidation, effectively protecting the main cable from corrosion and oxidation.

[0013] 4. This special anchor for photovoltaic main cables has novel design, simple structure and low cost. It only needs to open threads on the steel strand connector and lock the photovoltaic anchor anti-loosening cover to achieve the top tightening and double protection of the photovoltaic anchor, truly achieving low-cost and high-efficiency product design.

[0014] 5. Since the anti-loosening cover and anti-loosening cover of the photovoltaic anchor are connected to the steel strand connector and the photovoltaic anchor respectively through threads, when the clip needs to be replaced, you only need to loosen the anti-loosening cover of the photovoltaic anchor, take out the photovoltaic anchor support sleeve, and then loosen the anti-loosening cover to replace the clip, effectively protecting the safety of photovoltaic products.
