As shown in fig. 1, an embodiment of the present invention discloses a photovoltaic cable locking device, which includes a base 100, a locking device 200, and a limiting portion. Wherein the locking device 200 is mounted on the base 100, and the main rope 400 is placed between the first locking part and the second locking part through a gap between the first locking part and the second locking part. When the main rope 400 is locked, the first locking part and the second locking part are close to each other, so that the first locking part and the second locking part are abutted on the main rope 400 to lock and fix the main rope 400, and meanwhile, the relative movement between the first locking part and the second locking part is limited by the limiting part, so that the first locking part and the second locking part keep locking and fixing the main rope 400. When the first locking portion and the second locking portion are far away from each other, the main rope 400 is unlocked and can be pulled to slide between the first locking portion and the second locking portion along the self extending direction. Therefore, in the photovoltaic construction process, the main rope arranged in the photovoltaic support not only realizes locking and fixing of the main rope, but also can slide on the support so as to meet the pulling and adjusting requirements of the main rope.
As shown in fig. 1, the base 100 is provided with a receiving cavity, and the locking device 200 is placed in the receiving cavity, so that the receiving cavity of the base 100 not only protects the locking device 200, but also separates the locking device 200 from other surrounding parts, and interference of the surrounding parts to the locking device 200 is avoided in the using process of the locking device 200, thereby improving the convenience of operation of the locking device 200. In order to avoid interference of the side wall of the accommodating cavity with the main cable 400, the side wall of the accommodating cavity is provided with an avoidance groove 110, so that the main cable 400 passes through the base 100 through the avoidance groove 110 and is mounted on the locking device 200.
Meanwhile, in the sliding process of the main rope 400 in the photovoltaic cable locking device provided by the embodiment, in order to avoid the damage of the base 100 to the sliding main rope 400 caused by scratches, a U-shaped protective sleeve 300 is further arranged, and the protective sleeve 300 is clamped and fixed on the edge of the avoidance groove 110 through the clamping groove 310, so that the direct contact of the avoidance groove 110 to the main rope 400 is prevented, and the damage of the sliding main rope 400 caused by scratches is avoided.
As shown in fig. 2 and fig. 5, the inner wall of the clamping groove 310 of the protecting sleeve 300 is provided with a limit bump 311, and meanwhile, the edge of the avoiding groove 110 is provided with a limit groove 111, when the protecting sleeve 300 is clamped on the limit groove 111, the limit bump 311 is correspondingly embedded into the limit groove 111, and then the protecting sleeve 300 on the avoiding groove 110 is limited through the mutual matching of the limit bump 311 and the limit groove 111, so that the problem that the protecting sleeve 300 slides from the avoiding groove 110 and is separated in the use process is prevented.
In a specific embodiment, as shown in fig. 1 and 4, the locking device 200 includes a U-bolt 210 and a supporting block 220, the limiting portion includes a limiting nut 230, and the base 100 is provided with a first U-bolt mounting hole 120. The supporting block 220 is provided with a main cable accommodating groove 221 and a second U-shaped bolt mounting hole 222, when the supporting block 220 is clamped on the main cable 400 through the U-shaped bolt 210 and the supporting block 220, the main cable 400 is placed in the main cable accommodating groove 221, the supporting block 220 is abutted against one surface of the base 100, and the U-shaped bolt 210 passes through the base 100 and is in threaded connection with the limit nut 230 through the second U-shaped bolt mounting hole 222 of the supporting block 220 and the first U-shaped bolt mounting hole 120 of the base 100. The U-shaped bolt 210 and the supporting block 220 are close to each other by screwing the limit nut 230 and abutting on the other surface of the base 100, and finally abutting on the main rope 400, locking and fixing of the main rope 400 are achieved through the U-shaped bolt 210, the supporting block 220 and the limit nut 230, so that the U-shaped bolt 210 forms a first locking part, and the supporting block 220 forms a second locking part. When the limit nut 230 is reversely rotated, the limit nut 230 is far away from the base 100, so that a gap for sliding the main cable 400 can be formed between the U-shaped bolt 210 and the supporting block 220, thereby locking and fixing the main cable 400, and the main cable 400 can be pulled to be adjusted according to requirements.
Further, a round chamfer is formed on the edge of the main cable accommodating groove 221 of the supporting block 220, so that when the main cable 400 in the main cable accommodating groove 221 slides, the main cable 400 is prevented from being scratched and damaged by the edge of the main cable accommodating groove 221, and the protection capability of the main cable 400 in the use process of the photovoltaic cable locking device provided by the embodiment is further improved.
In a specific embodiment, the base 100 provided in this embodiment is manufactured by welding, and the base 100 is also welded and fixed to the cross beam 500 by welding.
