An upper sealing cover for a cable protection tube

Abstract

The invention relates to a cable protection pipe upper seal cover device, belonging to the technical field of power system line installation. The device comprises a cover body installed at a cable protection pipe upper seal, the cover body is C-shaped, a rotating cover that can rotate and can block the cover body covers the cover body, a cable insertion channel is provided at a C-shaped opening ofthe cover body, the cable insertion channel extends from the outer circumference of the cover body to the center of the cover body, the width of the cable insertion channel matches the outer diameterof the cable, the end of the cable insertion channel is designed to a semicircle attached to the outer wall of a cable, and a slot for inserting a cable protection pipe is formed in the middle of thelower surface of the cover body. The device has the advantages of convenient installation, strong sealing performance, water and leakage protection and long service life.

Description

technical field [0001] The invention relates to an upper sealing and capping device for a cable protection tube, which belongs to the technical field of power system line installation. Background technique [0002] At present, when installing cables, a galvanized cable protection tube 2.5-3 meters above the ground is often installed on the outside of the cable. The purpose is to protect the cable. The structure of the cable and the cable protection tube is as attached figure 1 As shown, after the protective tube is installed, it is necessary to seal the seal on the protective tube. In the past, the method of treatment was to insert cloth strips, plastic cloth, fireproof sludge, cement and other sealing materials 9 at the upper seal. figure 2 As shown, although such an approach can prevent rainwater from entering in a short period of time, after a long time, after being exposed to wind and sun, sealing materials such as cement and fireproof sludge will fall off, break, and ...

Problems solved by technology

In the past, the method of treatment was to insert cloth strips, plastic cloth, fireproof sludge, cement and other sealing materials 9 at the upper seal. figure 2 As shown, although this method can prevent rainwater from entering in a short period of time, after a long time, after being exposed to wind and sun, sealing materials such as cement and fireproof sludge will fall off, break, and melt.

Not only is it unsightly, but also rainwater will flow into the protection tube from the crack at the seal on the protection tube, forming water accumulation inside the protection tube, which will cause the protection tube to rust, corrode the outer material of the cable, and cause damage to people, equipment, and the power grid. huge security risk
