[0002] With the development of industrial technology, modern power distribution cabinet technology has become more and more perfect. In distributed photovoltaic power plants, the cables pulled from several arrays of solar panels on the power plant need to be bundled together and connected to the power distribution cabinet. There will be strong winds outdoors, and the cables will swing under the influence of wind and pull the equipment connected to their ends. When the cables swing, it is easy to pull down the distribution box;

[0003] Secondly, in high-latitude areas, the cables become brittle and hard in winter, and the cable sheath may crack and suffer other damages when it is shaken, and it is difficult to maintain when these faults occur. Summary of the invention

When the device is in use, the cables of the photovoltaic power plant are bundled and inserted through the inside of the clamping platform. The cables will sway in strong winds, and then the clamping platform will move under the traction of the cables. The movement of the clamping platform will be pulled by the first buffer rubber band and the second buffer rubber band. The greater the movement amplitude of the clamping platform, the greater the tension of the first buffer rubber band and the second buffer rubber band. Then the first buffer rubber band and the second buffer rubber band on the upper and lower side walls of the first buffer platform have a certain buffering effect on the clamping platform and the cables inside it to prevent the cables from being broken in strong winds, so as to solve the problems raised in the above-mentioned background technology.

In a cold environment, the looseness of the cables is increased, and the heating wire inside the clamping platform heats the cables inside it to reduce the hardness of the cables.
