Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, in particular to a cable laying device for a photovoltaic power station. Background Art

[0002] A cable laying device for a photovoltaic power station is a mechanical device or system specifically used for laying cables within the area of a photovoltaic power station. It aims to improve the efficiency, safety, and quality of cable laying.

[0003] For example, a wire and cable laying device (publication number: CN219420112U) includes a laying frame, pulleys, a cable setting roller, and a guiding assembly; the pulleys and the cable setting roller are arranged on the laying frame; a laying groove is arranged on the laying frame. By setting the guiding assembly, the guiding frame is used to guide the cable body to be laid extending from the cable setting roller, and by using the guiding seat slidably arranged on the guiding frame, the horizontal position of the guiding seat moves synchronously with the extending position of the cable body on the cable setting roller. A digital structure such as a single-chip microcomputer is set for the periodic sliding track of the guiding seat, so that after the cable body extends from the cable setting roller, it can reciprocally move on the sliding rod under the guidance of the guiding seat, thereby reducing the pulling between the cable body and the cable setting roller during the cable laying process and playing a better protective role for the cable body.

[0004] Based on the retrieval of the above patent and the combination with the equipment in the prior art, it is found that the above equipment lacks a structure for guiding and feeding the cable. The cable directly drives the movable guiding cylinder and the cable setting sleeve to move through the lead screw motor, and the cable is guided and laid by the cooperation of the movable guiding cylinder and the cable setting sleeve. The ends of the movable guiding cylinder and the cable setting sleeve directly contact the cable, which easily causes the cable to bend during cable laying, and the cable outer skin is easily damaged during the conveying process of the movable guiding cylinder and the cable setting sleeve. Therefore, we need to propose a cable laying device for a photovoltaic power station. Content of the Utility Model

In the laying mechanism, the laying motor drives the reciprocating lead screw to rotate, and the sliding block reciprocally moves through the reciprocating lead screw. Two laying wheels in the laying groove on the sliding block cooperate to lay the cable. As the sliding block moves, the mounting frame slidably arranged in the guiding and feeding mechanism moves synchronously to lay the cable, so as to solve the problems raised in the above background art.
