[0002] With the continuous expansion of photovoltaic projects, the installed capacity of mountain photovoltaic is also increasing. Part of the mountain photovoltaic slope is large, and the cable laying is more difficult. Cable untwisting refers to the phenomenon that the cable rotates after the torque is applied, wherein, when the cable is taken off from the cable reel, the cable is easy to rotate because of the torque stress generated during the winding of the cable, so that the cable is easy to produce kinks. Due to the complex terrain of mountain photovoltaic, it is difficult to eliminate the torque stress by using the traditional manual dragging and twisting method, and the large untwisting equipment is relatively bulky and inconvenient to transport.

[0003] Therefore, it is necessary to design a mountain photovoltaic cable outgoing line equipment which uses high-hanging cable to weaken the local torque stress of the cable. CONTENT OF THE UTILITY MODEL

[0021] The technical solutions in the embodiments will be described clearly and completely in combination with the drawings, and the described embodiments are only some of the embodiments, but not all, based on the embodiments in the embodiment, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the embodiment.

[0022] Example 1

[0023] like Figures 1-2 As shown in the figure, this embodiment designs a mountain photovoltaic cable outlet device, including a cable reel placement platform 1, a gate-shaped bracket 2, a fixed pulley 3, and a cable outlet mechanism.

[0024] The cable reel placement platform 1 can be in the shape of a frustum, a rectangular platform, a trapezoidal platform, etc. The upper surface of the cable reel placement platform 1 is flat to facilitate the placement of the cable reel 5 and the gate-shaped bracket 2.

[0025] One or more cable reel placement positions are provided on the upper platform. Each placement position can accommodate a cable reel 5. A limiting protrusion can be provided at each placement position, which can penetrate into the central hole of the cable reel 5 to prevent it from falling. For example: Figure 1 As shown, two spool placement positions are provided on the spool placement platform 1, and a fixed pulley 3 is provided at each of the two spool placement positions.

[0026] The portal frame bracket 2 is fixedly installed above the reel placement platform 1. The lower end of the portal frame bracket 2 can be placed on the reel placement platform 1 and pressed down by a counterweight, or the lower end of the portal frame bracket 2 can be fixed to the reel placement platform 1 with screws. The multiple reel placement positions are located below the same portal frame bracket 2.

[0027] One or more fixed pulleys 3 are installed on the crossbeam of the portal frame 2. The fixed pulleys 3 are generally located directly above the spool placement positions, and the number of fixed pulleys 3 corresponds one-to-one with the number of spool placement positions. Hooks for attaching to the cross arm 7 of the portal frame 2 are provided above the fixed pulleys 3.

[0028] The cable delivery mechanism includes a fixed body and a rotating body. The fixed body is used to fix and connect the cable reel 5. The rotating body is rotatably connected to the fixed body. A wire ring 9 is provided on the rotating body. When the cable 4 on the cable reel 5 is led outward, it passes through the wire ring 9 and wraps around the fixed pulley 3.

[0029] The fixing body includes a base 11 and a vertical shaft 10. The vertical shaft 10 is vertically arranged, and the base 11 is fixedly connected to the lower end of the vertical shaft 10. The base 11 is fixedly mounted on the cable reel 5. The rotating body includes a horizontal arm 7 and a diagonal arm 12. The horizontal arm 7, the diagonal arm 12, and the sleeve 6 are interconnected and form the three sides of a triangle. An extension arm 8 is provided at the end of the horizontal arm 7 away from the sleeve 6, and the wire ring 9 is fixed to the free end of the extension arm 8.

[0030] In use, the cable 4 wound on the cable reel 5 is first threaded into the wire guide ring 9, since the wire guide ring 9 is located radially outward of the cable reel 5, the cable 4 is prevented from rubbing against the edge of the cable reel 5, then the cable 4 is threaded through the fixed pulley 3, and then laid. Since the cable 4 is led upward by the fixed pulley 3 by a certain distance, the torque stress on the cable can be better transmitted along the cable 4, thereby reducing the phenomenon of excessive accumulation of local stress on the cable and kinking. The cable reel 5 is more easily laid in mountainous areas.

[0031] The above embodiments are merely examples for clearly illustrating the present application, and are not intended to limit the embodiments; all the embodiments are not required to be enumerated here. The obvious changes or modifications derived therefrom are still within the protection scope of the present application.
