Description

Technical Field

[0001] The utility model relates to the field of protective facilities for live working, in particular to a pole shielding cover. Background Art

[0002] In the live working tools, the shielding cover cannot play the main insulation role. It is only suitable for the protection of insulation shielding or isolation when the live working personnel have an accidental short collision, that is, when they touch by brushing. However, the role of the shielding cover cannot be ignored. It is a direct isolation protection structure for the live working personnel to accidentally touch the live conductor, and it is one of the necessary safety protection facilities in the live working.

[0003] Especially the pole shielding cover. During the installation of the pole, in order to avoid accidental contact between the pole and the wires, and during high-altitude power operations, in order to avoid contact between the pole and the personnel on the working platform, it is usually necessary to install a shielding cover on the outside of the pole. The current pole shielding cover is directly hooped and fits onto the outer wall of the pole. Because the shielding cover is elastic, it can be tightened to the outside of poles of different sizes. At the same time, the current shielding covers cannot connect multiple shielding covers in sequence to form overall protection for the pole. There may be gaps at the joints of adjacent shielding covers, which poses a risk of leakage and is not safe to use. Utility Model Content

[0029] The outer wall of the cover body 1 is recessed inward to form an inner protrusion 103 which is respectively arranged in the groove 104 on the outer side of the cover body 1. The protrusion 103 and the groove 104 cooperate to form a buckling part that connects adjacent cover bodies 1 end to end. In this way, the connection and locking of the two sides of the cover body 1 can be achieved through the buckling part at the overlapping part of the two edges, so that it can be stably buckled to the outer circumference of the pole. In addition, adjacent shielding covers can be inserted and overlapped, which ensures the requirement for the overlapping distance of the shielding covers in live working and also realizes the combined connection of multiple shielding covers.

[0030] As an optional embodiment, the buckle parts are evenly distributed in a rectangular array along the outer wall of the cover body 1, and the protruding surface of the convex block 103 toward the center of the cover body 1 gradually decreases, thereby reducing the contact area between the cover body 1 and the inner pole, and forming a cavity between the cover body 1 and the pole, which can also provide an anti-collision buffering effect during the installation of the pole, and the convex block 103 can be snap-fitted with the groove 104, and the convex block 103 and the cover body 1 are integrally formed;
