[0002] In recent years, with the development of my country's photovoltaic industry, the photovoltaic industry has become one of the symbols of my country's advanced manufacturing industry; due to the complex environment of photovoltaic installation, the cable must withstand stronger tensile loads and strong impacts. Therefore, in the photovoltaic industry, naturally cross-linked photovoltaic cables with higher cable sheath strength are usually used; existing photovoltaic cable laying devices are usually equipped with cable rollers. Naturally cross-linked photovoltaic cables have stronger tensile resistance. When it is necessary to lay cables, the cable rollers are driven by manual traction to rotate, so that the cable laying can be achieved. However, some cable rollers are heavy and large in size. Therefore, when the manpower stops pulling the cable, the cable rollers still maintain a strong inertia, which will cause the excess cable to keep Fly out; The patent with publication number (CN116435913A) in the prior art provides a cable installation device applied to photovoltaic equipment, including an installation device base and a cable roller, the top of the installation device base is fixedly connected with a photovoltaic equipment cable bracket, the top of the photovoltaic equipment cable bracket is fixedly connected with a limited shaft seat, a central axis is provided at the axis of the cable roller, the central axis is movably clamped in the limited shaft seat, the top of the installation device base is fixedly connected with a limited sleeve, the top of the limited sleeve is provided with a cable positioning pulley, the bottom of the cable positioning pulley is fixedly connected with a rotating column, the bottom of the rotating column is fixedly connected with a positioning wheel, and the positioning wheel) is rotatably connected in the limiting sleeve.

The rotation of the connecting rod 83 drives the push rod 84 to make a horizontal reciprocating motion. Since the push rod 84 is fixedly connected to the brake block 7, the brake block 7 makes a horizontal reciprocating sliding with the push rod 84.

[0025] In an optional embodiment, if Figures 1 to 3 , Figure 7 and Fig.11As shown, in order to meet the overall rotation of the two groups of fixed pulleys 641, the guide pulley device 6 includes a column 61 and an axle seat 62.

[0028] Working principle: the cable passes through the bottom of roller 2 51 and the top of roller 1 41 in sequence, then enters the horizontally arranged fixed pulley set 64, and finally extends out from the vertically arranged fixed pulley set 64; first, rotate the turntable 60 to adjust the angle of the fixed pulley set 64 so that the fixed pulley set 64 arranged vertically at the front end faces the direction where it needs to appear; the operator pulls the cable to lay it, and the cable will lift the roller 2 51 after being stressed, and the sliding column 53 of the roller 2 51 will rise, and the brake block 7 will be pushed to shrink through the connecting rod mechanism 8 to disengage the brake on the baffle plate 21 of the cable roller 2; when the operator stops pulling, the cable is not stressed, and the sliding column 53 slides downward under the action of gravity and drives the connecting rod mechanism 8, and the brake block 7 is quickly extended and reset under the dual drive of the spring S and the connecting rod mechanism 8, so as to achieve the brake on the baffle plate 21 of the cable roller 2.

[0029] The beneficial effects of the present invention are as follows: by arranging two groups of fixed pulley blocks, one group of fixed pulley blocks is arranged horizontally to bear the force of the cable swinging left and right in the horizontal direction, and the other group of fixed pulley blocks is arranged vertically to bear the force of the cable swinging up and down in the vertical direction, and a roller assembly is added at the same time, the cable can be adjusted to the same height as the wire passing opening of the fixed pulley block before entering the fixed pulley block. When the two groups of fixed pulleys are rotated to a larger angle as a whole, the cable first enters the horizontal fixed pulley block, and the horizontal fixed pulley block bears the left and right forces to make a turn for the cable before entering the vertical fixed pulley block, so that it will not be manually pulled in a predetermined direction. Hard friction occurs with the inner wall of the vertical fixed pulley group, and the vertical fixed pulley bears the force in the up and down swinging direction. In this way, there is a corresponding pulley transition at each turning point of the cable. Manual traction is not only labor-saving but also free of hard friction between the cable and the device during the whole process. By setting a brake block and a connecting rod mechanism cooperating therewith, it can be achieved that when the cable is manually pulled, the cable lifts drum two, and drum two drives the connecting rod mechanism to push the brake block to disengage from the brake on the cable roller. When the traction stops, drum two resets and drives the connecting rod mechanism to reset. Through the action of the connecting rod mechanism and the brake block spring, the brake block extends out to restore the brake on the cable roller.
