[0002] Photovoltaic power generation components can be installed above the water surface in hills, mountains, tidal flats, fish ponds, reservoirs, etc. For installation in places with poor terrain, photovoltaic flexible brackets are required for installation. Photovoltaic flexible brackets mainly include bracket bodies, cable bodies such as steel strands, and anchors. The ends of cable bodies such as steel strands need to be anchored by anchors to achieve clamping and fixing of the ends of the cable bodies.

[0003] The anchor structure of the existing photovoltaic flexible bracket is relatively simple, and there is a lack of anti-corrosion design for the anchor in the outdoors. Rainwater, dust, etc. can easily enter the interior of the anchor, causing corrosion to the clips, anchor plates, prestressed tendons, etc., affecting the service life. In addition, the long-term swinging and shaking of the anchor and the cable under the action of the wind can easily cause the anchor system to loosen, further aggravating the damage of the anchor structure. Damage to the anchor structure will cause the collapse of the photovoltaic flexible bracket. There has always been a lack of an anchor structure with a reasonable structure, easy installation, and anti-corrosion function to effectively solve this technical problem. Summary of the invention

[0036] Referring to the attached drawings of the specification, this application optimizes the anti-corrosion design of the photovoltaic flexible bracket, provides closed protection for the anchoring ends such as the cable body and anchor plate, and also provides anti-corrosion protection for the cable body close to the anchor, so that the anchor and the cable body end achieve good anti-corrosion and protection effects. Maintenance-free after installation not only effectively avoids rust and aging of the anchor, but also prevents it from loosening even when it is subjected to long-term wind swing and vibration, thus extending its service life. The specific structure and principle are as follows:

[0037] The cable body 1 is a variety of cable body structures such as slow-bonding prestressed tendons, epoxy non-bonding prestressed tendons or galvanized prestressed tendons. An anchor plate 2 is provided with a mounting hole, which is set as a tapered hole structure. One end of the cable body 1 is inserted into the mounting hole of the anchor plate 2, and the large hole end of the mounting hole is located at one side of the end of the cable body 1. The anchor plate 2 can also be set as a structural form of an anchor seat, and a steel pad 3 is set at the outer end of the anchor plate 2. A wedge-shaped locking member 4 is installed between the outer surface of the cable body 1 and the mounting hole. The cable body 1 is locked and fixed on the anchor plate 2 through the wedge-shaped locking member 4. The wedge-shaped locking member 4 is a wedge-shaped clip or a conical cylinder structure. The small end of the wedge-shaped clip or the conical cylinder structure faces the tensioning end. When the cable body 1 is subjected to tension, the wedge-shaped locking member 4 will squeeze the cable body 1 and act on the anchor plate 2 or the anchor seat. The greater the tension on the cable body 1, the greater the locking force generated.

[0038] An anti-loosening gland 5 is installed at the outer end of the anchor plate 2 and located outside the wedge-shaped locking member 4. The anti-loosening gland 5 is fixed to the outer end of the anchor plate 2 by threaded fixing or clamping to prevent the wedge-shaped locking member 4 from withdrawing outward. In order to further enhance the fixing effect of the wedge-shaped locking member 4, the present application installs an anti-loosening spring between the wedge-shaped locking member 4 and the anti-loosening gland 5. One end of the anti-loosening spring presses against the outer end of the wedge-shaped locking member 4, and the other end of the anti-loosening spring presses against the anti-loosening gland 5. The anti-loosening spring can be a double butterfly spring 6.

[0039] A protective cover 13 is provided outside the anchor plate 2 and outside the entire anchor. One end of the protective cover 13 is open and the protective cover 13 is fixed to the anchor plate 2 or the steel pad 3 by threaded connection. A sealing structure is provided at the joint between the protective cover 13 and the anchor plate 2. The sealing structure includes a protective cover sealing material 14 and a sealing ring 8 located at the outer end. The protective cover sealing material 14 adopts a sealing tape, a non-flowing non-solidifying sealing material, and an elastic sealing ring 8 is provided at the joint between the outer end of the protective cover 13 and the anchor plate 2 or the steel pad 3.

[0040] In addition, in order to improve the protective effect of the cable body 1, the present application provides a cover 9 sealed with the surface of the cable body 1 at one end of the sheath tube 11 close to the anchor plate 2, and a cover 9 or a heat shrink sleeve 12 is provided at the connection portion between the other end of the sheath tube 11 and the surface of the cable body 1, and a weather-resistant sealing ring 15 is provided between the outer end of the cover 9 and the surface of the cable body 1.
