Embodiment 1

[0036] This embodiment provides a cable protection tube dredging device, which includes a dredge 2 that can move back and forth in the cable protection tube 1 to crush and clean the mud, and a dredge that can move back and forth in the cable protection tube so that the dredge cannot be collected. The broken soil collector for collecting broken soil, the scourer that can move in the cable protection tube and use high-pressure water flow to wash away the sundries that cannot be collected by the dredger and the broken soil collector, can move in the cable protection tube and pass high-pressure airflow A blower that blows out the accumulated water in the cable protection tube, a wiper that can move back and forth in the cable protection tube to wipe off the water on the inner wall of the cable protection tube, and a hot blower that can move back and forth in the cable protection tube to dry the inside of the cable protection tube It also includes a driving device that can respectiv...

Embodiment 2

[0055] Embodiment 2 is on the basis of Embodiment 1. It is also provided with a control unit for controlling the on-off of the motor switch, which is located at both ends of the cable protection tube to detect the status of the dredger entering and exiting the cable protection tube. The infrared detection The device is electrically connected to the control unit; the control unit controls the two driving devices to act alternately according to the feedback information of the infrared detector, specifically: when the driving device I operates, the driving device II does not operate, and the cable is stretched out after the infrared detector detects the dredger, etc. When the protection tube is at one end of the driving device I, the two driving devices are controlled to operate alternately (the driving device I does not operate, and the driving device II operates), and so on.

Abstract

The invention relates to a dredging device and method for a cable protective pipe. The dredging device comprises a dredger, a pulverized soil collector, a flusher, an air blower, a wiper and a hot air blower, and further comprises a drive device and a controller. The device completely solves the dredging problem of the cable protective pipe, and improves cleanliness in the cable protective pipe, so that the cable protective pipe achieves a good protection effect on a cable.

Description

technical field [0001] The invention relates to the field of electric power construction, in particular to a device and method for dredging a cable protection pipe. Background technique [0002] As a trenchless construction technology, cable jacking construction technology is generally applicable in the cable laying process in the power industry. The main process includes exploration of underground cable paths, pipe jacking conduction, underground penetration of cable protection pipes, and laying of power cables through pipes. Among them, in the underground penetration link of the cable protection pipe, during the process of pulling the cable protection pipe (PE pipe) by the underground reamer, due to the poor sealing of the cable protection pipe mouth and scratches by underground hard objects (stones, tiles, etc.), It will often cause part of the soil to enter the pipe, which will easily cause the internal blockage of the laid cable protection pipe, which will affect the l...
