Description

Technical Field

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

[0002] The laying of photovoltaic cables is an important part of rooftop distributed photovoltaic power generation projects. During construction, because the photovoltaic cables are relatively thin in diameter and the laying volume is large, the laying is relatively complicated. Improper laying can easily cause entanglement and twisting. The original method of placing rotatable bearings under the cable reel requires workers to rotate the cable reel at the cable reel, and people laying the cables at a distance must pull them at the same time. A high degree of coordination is required, otherwise the cable tension is too great and it is easy to cause damage. Utility Model Content

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0018] As shown in the figure, the utility model discloses a rotating bracket device for laying photovoltaic cables, including a cable drum 1, a longitudinal angle steel bracket 2, a transverse angle steel bracket 3 and a metal ring 4. The cable drum 1 is placed flat on the ground, and a bearing 5 is installed at the center disk hole of the cable drum 1. The inner ring of the bearing 5 is installed at the lower end of the longitudinal angle steel bracket 2. A metal ring 4 for passing through the photovoltaic cable is installed on the top of the longitudinal angle steel bracket 2. The transverse angle steel bracket 3 is installed at the lower end of the longitudinal angle steel bracket 2, and a circular hole 31 is opened at the end of the transverse angle steel bracket 3.

[0019] The length of the longitudinal angle steel bracket 2 is 1.5m, and the longitudinal angle steel bracket 2 extends into the bearing 0.2m. The angle between the longitudinal angle steel bracket 2 and the hypotenuse is as close to 30° as possible to facilitate the laying of cables high on the roof. The end of the longitudinal angle steel bracket 2 is equipped with a metal ring 4 for passing the photovoltaic cable. The length of the transverse angle steel bracket 3 is 0.6m.

[0020] In one embodiment of the present invention, the horizontal angle steel bracket 3 and the vertical angle steel bracket 2 are perpendicular, that is, the included angle is 90 degrees.

[0021] In one embodiment of the present utility model, the transverse angle steel bracket 3 and the longitudinal angle steel bracket 2 are connected by bolts 7, and the bolts 7 are connected at the intersection of the transverse angle steel bracket 3 and the longitudinal angle steel bracket 2 0.1m above the upper end surface of the cable reel. The transverse angle steel bracket 3 is located at the upper end of the cable reel 1.

[0022] In one embodiment of the present invention, one end of the photovoltaic cable 6 passes through the circular hole 31 and the metal ring 4 at the end of the horizontal axis angle steel bracket 3, and then is pulled to the factory roof. Through the oblique pulling force of the roof, the bracket naturally rotates clockwise to realize the laying of the photovoltaic cable.

[0023] In one embodiment of the present invention, two vertically arranged mounting holes 21 are provided on the top of the longitudinal axis angle steel bracket 2 , and the metal rings are installed at the two mounting holes 21 .

[0024] In one embodiment of the present invention, the cable drum 1 includes two stop plates 11 and a central shaft 12. The central shaft 12 is mounted between the two stop plates 11. The bottom stop plate 11 rests flat on the ground, and the bearing 5 is mounted in the center hole of the top stop plate 11. The stop plate 11 is a circular disk with a radius of 0.4m.

[0025] The utility model has a simple structure and uses less materials. It only requires measuring the size of the center hole of the photovoltaic cable reel in advance, configuring a bearing of corresponding size and fixing it on the limit plate 11, using an angle steel bracket of appropriate size or cutting or grinding the angle steel bracket to form a longitudinal angle steel bracket 2, and then clamping the longitudinal angle steel bracket 2 on the inner ring of the bearing and fixing it firmly, thereby completing the construction of the rotation system. The transverse angle steel bracket is determined according to the radius length of the cable reel, and the length of the longitudinal angle steel bracket is determined according to the length of the transverse angle steel bracket, the height of the transverse angle steel bracket from the reel surface and other information. Finally, a simple rotating bracket device for cable laying is formed by reliable connection. The bracket device gets rid of the traditional laying method and no longer needs to be manually rotated. The cable is automatically detached from the cable reel by rotating the bracket in circles, and finally the laying effect is achieved.

[0026] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
