Problems solved by technology

[0002] In the process of line maintenance, due to the limitation of the structure of the suspension insulator itself, when replacing the insulator on the cross arm, it is necessary to effectively insulate the cross arm and the insulator, and remove the fixed wire on the insulator before the insulator can be replaced. , After replacing the new insulator, fix the wires on the new insulator. The original work is covered with an insulating blanket. When in use, the operator wraps the cross arm near the insulator with the insulating blanket, and then supports the insulation The board is clamped on the cross arm wrapped with insulating blanket, and then the wires fixed on the insulator are removed, the wires are placed in the insulating clamping board, the insulating clamping board is placed on the insulating support board, and a new insulator is replaced. When wrapping the blanket, personnel are required to wrap the insulation blanket on the cross arm. Many tools are required, and the operation is very complicated and cumbersome. The general operation takes 15 minutes, and the work efficiency is low. If the insulation blanket is not wrapped or the wrap is not firm , it is easy to cause the insulation blanket to fall, causing electric shock accidents. The material of the insulation blanket is soft and in contact with the hard cross arm, which is easy to be damaged. Completely shield the suspension insulator, and there is a problem that the shielding effect is not good
[0003] The notification number CN203589594U provides a suspended insulator shield, which includes a connecting plate and a pair of arc-shaped shielding plates hinged on both sides of the connecting plate respectively, and semicircular Shaped baffle, a groove is opened at the center of the semicircular baffle, a pair of arc-shaped shielding plates and the circular baffle form a cylindrical shielding cover, and an installation handle is fixed on the connecting plate, However, this
