Termite-proof and rat-proof cable plugging

Abstract

The invention relates to a termite-proof and rat-proof cable plugging, which comprises a flexible rubber block, outer pressure plates, square-head bolts, inner pressure plates and nuts, wherein the flexible rubber block comprises a first expansion block and a second expansion block; pressure plate grooves are formed in the front and back side surfaces of the first expansion block and the second expansion block; the outer pressure plates and the inner pressure plates are arranged in the corresponding pressure plate grooves in the front and back side surfaces of the flexible rubber block separately; through holes are formed in corresponding positions of the flexible rubber block, the outer pressure plates and the inner pressure plates; fixed seats are arranged at the outer sides of the through holes in the inner pressure plates; and the square-head bolts sequentially pass through the inner pressure plates, the flexible rubber block and the outer pressure plates and are in screw-thread fit with the corresponding nuts. According to the termite-proof and rat-proof cable plugging, the phenomena of flooding and termite and rat entering caused by damage to a rigid cable plugging are avoided, and cables and other electric equipment are effectively protected.

Description

technical field [0001] The invention relates to a cable plug, in particular to a termite-proof and rodent-proof cable plug. Background technique [0002] The purpose of sealing or blocking the opening of the underground cable duct is to keep the cable duct network in a clean and dry environment for a long time, and the extremely destructive termites and rodents cannot enter the cable duct network for damage. It is to create a good working environment for the later repair and maintenance. However, due to various reasons, many underground cable duct plugging projects have not been done well in the past, resulting in cables being bitten by termites or rodents, causing great difficulties in later repairs or maintenance operations, not only delaying repairs It also increases the cost and difficulty of construction. Now, with the acceleration of urbanization and the improvement of the national power department's quality standards and construction grades for underground cable pro...

AI Technical Summary

Problems solved by technology

The material of this method is greatly affected by thermal expansion and contraction, the duration of waterproof and anti-leakage effects is very short, and it cannot effectively prevent termites. Generally, it needs to be redone after two or three years; rigidly sealed cables cannot be moved at short intervals position and bending, which is not conducive to later construction and maintenance; on-site mixing is required during construction, and the requirements for construction materials, tools, mixing and transportation are relatively high; if it needs to be knocked when dismantling, it is troublesome and easy to cause damage to the pipeline

In order to solve such problems, there is an urgent need for a new product to solve a series of problems that cannot be effectively waterproofed and termite-proofed due to rigid sealing
