DETAILED DESCRIPTION

[0017] The following will be combined with the drawings of the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] This embodiment provides a photovoltaic high-voltage cable laying device, such as Figure 1 As shown, the photovoltaic high-voltage cable laying device includes a set of brackets 1 located on the left and right sides of the cable reel 2, and is composed of two parts, a support shaft 3 passing through the center of the cable reel 2. Among them, the bracket 1 is used as a support body, the purpose of which is to prop up the cable reel 2 so that its bottom is out of contact with the ground; the support shaft 3 is a central rotating shaft, the purpose of which is to enable the cable reel 2 to rotate between the brackets 1 on the left and right sides through the support shaft 3 to realize the high-voltage cable pay-out action.

[0019] like Figure 1 and Figure 2 As shown, the bracket 1 includes a group of symmetrically arranged triangular frames 7. The triangular frames 7 are made of steel pipes. The top of the triangular frames 7 is welded and fixed to the top steel plate 8, and the bottom is welded to the angle steel frame 9 in contact with the ground. Two guide support columns 10 are symmetrically arranged between the top steel plate 8 and the angle steel frame 9 inside the bracket 1. The guide support columns 10 are made of steel pipes. The top is welded and fixed to the top steel plate 8, and the bottom is welded and fixed to the angle steel frame 9. The overall height of the bracket 1 is greater than the radius of the cable reel 2. A jack placement platform 4 and a support seat 6 are installed between the two guide support columns 10. The jack placement platform 4 is a plate structure, and the support seat 6 is a seat body. Both sides of the support seat 6 are slidably mounted on the two guide support columns 10 through an annular body. A jack 5 is placed on the jack placement platform 4. The top rod of the jack 5 is connected to the bottom of the support seat 6. The top rod of the jack 5 is controlled to rise and fall, so that the support seat 6 moves vertically in the bracket 1. Considering the convenience of the movement of the bracket 1, as shown in FIG. Figure 1 As shown, in this embodiment, a pair of traveling wheels 16 are installed on the side of the angle steel frame 9 away from the cable reel 2 .

[0020] like Figure 1As shown, in this embodiment, a number of connecting angle steels 11 are arranged in an equiangular circumferential direction on the left and right end faces of the cable reel 2, and the extended ends of the connecting angle steels 11 are fixedly connected to the disc bodies on the left and right sides of the cable reel 2 by bolts; at the same time, the support shaft 3 passes through the center of the cable reel 2, and one end of the connecting angle steel 11 is welded and fixed to the support shaft 3 at the center of the circle on the left and right sides of the cable reel 2. The two ends of the support shaft 3 are supported by the support seats 6 on the brackets 1 on the left and right sides of the cable reel 2 at the same time, and the height of the support shaft 3 and the cable reel 2 is raised by controlling the jack 5, so that the bottom of the cable reel 2 can be rotated between the brackets 1 on the left and right sides after it is out of contact with the ground.

[0021] Furthermore, since the diameters of the cable reels 2 of the high-voltage cables vary during the photovoltaic high-voltage cable laying construction, in order for the photovoltaic high-voltage cable laying device to be adaptable to the cable reels 2 of different diameters, such as Figure 1 and Figure 2 As shown, in this embodiment, a plurality of positioning through holes 14 are arranged at equal intervals on the two guide support columns 10, and at the same time, the two sides of the jack placement platform 4 are slidably mounted on the two guide support columns 10 through annular bodies, and two pins 15 passing through the positioning through holes 14 are used to lower the annular bodies on both sides of the jack placement platform 4 to form a positioning function, so that the bracket 1 can meet the support function of cable reels 2 of different diameters.

[0022] In addition, in order to reduce the rotation resistance of the support shaft 3 relative to the support seat 6, as Figure 3 As shown, in this embodiment, an arc groove 12 that cooperates with the support shaft 3 is formed at the center position of the support seat 6, and a roller 13 is symmetrically installed in the arc groove 12. The roller 13 is in contact with the support shaft 3 to reduce the rotational resistance of the support shaft 3 relative to the support seat 6.

[0023] The method of using the photovoltaic high-voltage cable laying device is as follows:

[0024] First, use a crane to erect the cable reel 2 of the high-voltage cable, and pass the support shaft 3 through the center of the cable reel 2. By placing brackets 1 on the left and right sides of the cable reel 2, respectively, use the jack 5 on the jack placement platform 4 of the bracket 1 and the support seat 6 that can move vertically in the bracket 1 to support the two ends of the support shaft 3; use the jack 5 to lift the overall height of the support shaft 3 and the cable reel 2 so that the bottom of the cable reel 2 can be separated from the ground and rotated between the brackets 1 on the left and right sides, and use the wire puller to pull the outlet end of the high-voltage cable, so as to realize the rapid laying of high-voltage cables and improve the efficiency of engineering construction.
