Description

Technical Field

[0002] Transmission line icing is an important factor affecting the safe operation of power grid lines. Generally speaking, overhead transmission lines are erected above the ground and directly exposed to the external environment. In cold weather seasons, the surface of the line cables is prone to ice and snow. The presence of icing will greatly increase the weight of the transmission line cables, and the mechanical stress of the line will change accordingly, which will affect the overall working performance of the transmission line and make it impossible to ensure the smooth transmission of electricity. Severe icing can cause ground short circuits, line breaks, and even tower collapse accidents, which are extremely harmful.

[0003] In order to solve the problem of icing on transmission lines, the power grid adopts de-icing devices of various structures to clean the transmission lines. However, in major practical applications, it is necessary to first solve the problem of the movement of the de-icing device on the transmission lines. In view of this, the movement structure of the de-icing device adopted in the prior art is relatively complex, the movement direction is inconvenient to control, and the cost is high, which makes the energy consumption of the entire de-icing device too high and the de-icing efficiency cannot meet expectations.

[0030] It should be noted that the number and shape of the deicing blade heads are determined by the actual icing conditions of the transmission line, and their positions can be respectively set at the upper and lower positions of the transmission line to remove ice from the upper and lower parts; the deicing blade seat can be tightly connected with the deicing blade head through a compression spring, and the pressure generated by the spring compression ensures that the deicing blade head is in close contact with the transmission line. At the same time, the spring ensures the fixed state of the deicing blade head to prevent the deicing effect from being greatly reduced due to the shaking between the deicing blade head and the transmission line.
