Underground communication pipe rodent-proof cover

Abstract

The invention discloses an underground communication pipe anti-rat cover comprising two pipe filling half bodies. Each pipe filling half body comprises a semicircular cover plate and an annular guide plate arranged at the lower end of the semicircular cover plate. The straight edge of each semicircular cover plate is provided with two symmetrical semicircular openings. The outer arc edge near each semicircular cover plate is provided with a filling through hole, a fixed duct is fixedly arranged at the lower end of the filling through hole, and the lower end of the fixed duct is fixedly connected with an elastic filling capsule. A clamping device is arranged on each pipe filling half body. When the two pipe filling half bodies are in butt joint, every two semicircular openings facing each other form a threading hole. The large threading holes formed through butt joint of the two pipe filling half bodies allow communication cables of different types to pass through. Meanwhile, gaps around a cable can be filled by filling an appropriate amount of filler in the elastic filling capsules, and dustproof and anti-rat effects are achieved.

Description

technical field [0001] The invention relates to a pipeline blocking end cover, in particular to a rodent-proof cover for an underground communication pipeline. Background technique [0002] With the continuous development of network technology, more and more communication and power transmission cables are erected underground in large, medium and small cities. Due to the dark and humid environment in underground pipelines and tube wells, it has become an ideal habitat for mice. Because the communication and transmission cables are moderately soft and hard, it has become an ideal molar material for mice. In areas where mice are densely populated, mouse bites often occur The power transmission and communication failure caused by it. The Chinese patent with authorized notification number CN 204464921 discloses a new type of rodent-proof cover for underground communication pipelines. The wire hole, and the wire hole passes through the cover body, and an opening communicating wi...

AI Technical Summary

Problems solved by technology

However, in the actual application process, the above-mentioned anti-rat cover has the following problems: 1. There is only one wire hole, which can only allow one cable to pass through. Two cables are installed in the pipeline, so the application range of the above-mentioned rodent-proof cover is relatively narrow; 2. Because there are many types of cables, the diameters of the cables are also different, which leads to the gap between the cables and the wire holes. The gaps between the gaps are large and small. Although the gaps are filled with fillers to prevent mice from entering, when the gaps are too large, it is not so easy to fill the gaps with fillers.
