Embodiment 1

[0028] A pole shield provided in this embodiment, such as figure 1 As mentioned above, it includes: a cover body structure, at least including a first cover body 1 and a second cover body 2 sleeved outside the first cover body 1, the first cover body 1 and the second cover body 2 are respectively openable and closable A cylindrical structure set on the pole; the inner diameter of the first cover body 1 closely matches the outer diameter of the pole so that the first cover body 1 cannot move downward relative to the pole under the action of gravity, and the second cover body The inner diameter of 2 is greater than the outer diameter of the first cover body 1 so that the second cover body 2 can fall freely relative to the first cover body 1 under the action of gravity; When the electric pole is on, the second cover body 2 is prevented from breaking away from the first cover body 1 from the lower end of the first cover body 1 .

Abstract

The invention discloses an electric pole shield. The electric pole shield comprises a shield body structure and a first anti-shedding structure, wherein the shield body structure at least comprises afirst shield body and a second shield body set outside the first shield body, the first shield body and the second shield body are tubular structures set on an electric pole in a foldable mode, the inner diameter of the first shield body is tightly matched with the outer diameter of the electric pole to make the first shield body be unable to move downwards relative to the electric pole under theaction of gravity, the inner diameter of the second shield body is greater than the outer diameter of the first shield body to make the second shield body freely fall relative to the first shield bodyunder the action of gravity, and the first anti-shedding structure is suitable for preventing the second shield body from being disengaged from the first shield body from a lower end of the first shield body when the shield body structure is set on the electric pole. The electric pole shield is advantaged in that the shield body structure is set to have the first shield body and the second shieldbody set outside the first shield body, adjustment on length of the electric pole shield can be realized through adjusting the overlapping portion between the first shield body and the second shieldbody, and a problem of fixed length of an electric pole shield in the prior art is solved.

Description

technical field [0001] The invention relates to insulation and shielding equipment for live work, in particular to a retractable pole shield. Background technique [0002] According to the electric safety regulations, during the live operation of 10kV overhead power distribution lines, the operator should keep a safe distance of 0.4 meters and 0.6 meters from the grounding body. Effective insulation and shielding measures for the grounding body. The 10kV pole is equipped with a grounding wire, the root is buried deep in the ground, and metal devices such as cross arms are installed on the upper part, which is the largest grounding body that operators may touch during operation. Therefore, operators need to effectively insulate and shield the poles according to the actual situation on site. The pole shielding cover is a shielding tool commonly used in power distribution live work. , power grid and equipment security. [0003] In the prior art, the Chinese patent document ...
