Pneumatic high-frequency impact penetration viewfinder for cable duct

Abstract

The invention discloses a pneumatic high-frequency impact penetration viewfinder for a cable duct. The pneumatic high-frequency impact penetration viewfinder is fixedly connected to one end of a glassfiber tube; the glass fiber tube is connected with one end of a glass fiber tube connector through a bolt; a camera is mounted at the outer side of the glass fiber tube connector; a transmission device is arranged inside the glass fiber tube; the other end of the glass fiber tube connector is connected with a rotary push-in sleeve through a connecting baffle plate; the connecting baffle plate isin sealing connection with the inner wall of the rotary push-in sleeve; an impact block piston is arranged inside the rotary push-in sleeve; and the outer wall of the impact block piston is in slidingconnection with the inner wall of the rotary push-in sleeve. The pneumatic high-frequency impact penetration viewfinder can effectively solve a blocking condition in the cable duct, monitors the blocking condition in the cable duct in real time, can perform high-frequency impact penetration on a blocked object, drives the glass fiber tube to effectively pass through the cable duct, is simple in structure, and greatly improves cable duct penetrating and dredging efficiency.

Description

technical field [0001] The application relates to the technical field of cable duct dredging and inspection devices, in particular to a pneumatic high-frequency impact penetrating viewer for cable ducts. Background technique [0002] When installing cables in wells and cable ducts for the second time, operators often need to use FRP pipe piercers to dredge the cable ducts or wells. During the construction process, when encountering wells with serious siltation, the functions of the pipe piercers are limited. , The dredging effect is not good. In addition, the structure of the shaft and cable duct is deformed or the cables are crossed, and the existing dredging tools rely entirely on manual experience and tentative blind operations, which cannot predict the internal conditions of the shaft, and the operation efficiency is low. Contents of the invention [0003] In order to overcome the weak and low efficiency of the existing cable duct dredging technology, the present inve...
