Abstract

The invention relates to an anti-skid soft insulation shielding tube for live working, which comprises at least one group of insulation shielding tube bodies which are connected end to end, each group of insulation shielding tube bodies comprises an opening part which is arranged on the tube wall of the insulation shielding tube body along the axis direction, and anti-skid hairs are arranged on the inner wall of the insulation shielding tube body. One end of the insulating shielding tube body is connected with the inner concave part, the other end is connected with the outer bulge, and the inner concave part is matched with the outer bulge in structure. When the plurality of insulation shielding tubes are used, the outer protrusions are embedded into the inner concave portions of the adjacent insulation shielding tubes to form locking, the locking structure meets the requirement for the safe distance of the overlapped portions of the two adjacent insulation shielding tubes, and the phenomenon that when non-parallel erected linear materials are subjected to insulation shielding, the linear materials cannot be blocked is avoided. And the insulating shielding object is easy to slide down along the linear material.

Description

technical field

[0001] The invention relates to the field of semiconductor components, in particular to a non-slip soft insulating shielding tube for live work. Background technique

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] During the live work of the distribution line, in order to avoid short-circuit or grounding causing personal, power grid and equipment damage, the operator needs to insulate and shield the adjacent live objects and grounding objects. For example, in the live operation of 10kV overhead distribution lines, when insulating and shielding overhead wires, drain wires, and pull wires, insulating shielding tubes or insulating blankets are usually used. However, due to the effect of gravity, for the non-horizontal overhead wires, drainage wires and pull wires, after the insulating shielding is completed, the insulating shielding material may ...

Examples

Embodiment 1

[0036] like figure 1 As shown, the purpose of this embodiment is to provide a non-slip soft insulating shielding pipe for live work, comprising at least one group of insulating shielding pipe bodies 4 connected end to end, and each group of insulating shielding pipe bodies 4 is included in the insulating shielding pipe body. 4 is an opening 5 arranged along the axial direction on the pipe wall of the insulating shielding pipe body. The inner wall of the insulating shielding pipe body is provided with anti-skid hairs 3. The structure of the outer protrusion 6 is matched.

[0037] One end of the insulating shielding pipe body 4 is connected to the pipe head 1, the pipe head 1 is annular, the inner surface of the pipe head 1 is connected to the outer surface of the insulating shielding pipe body 4, and the groove located in the inner circumferential direction of the pipe head 1 forms an inner recess. 2. The outer diameter of the pipe head 1 is larger than the outer diameter of ...
