Embodiment 1

[0036] This embodiment provides a cable protection pipe dredging device, which includes a dredge that can move reciprocally in the cable protection pipe 1 to crush and clean the mud. 2. It can move back and forth in the cable protection pipe to prevent the dredge from being collected. The crushed soil collector that collects the crushed soil, the scourer that can move in the cable protection pipe and wash the debris that can not be collected by the dredge and the crushed soil collector through the high-pressure water flow, and can move in the cable protection pipe and pass the high-pressure airflow A hair dryer that blows out the water in the cable protection tube, a wiper that can reciprocate in the cable protection tube to wipe the water on the inner wall of the cable protection tube, and a hot air blower that can reciprocate in the cable protection tube to dry the cable protection tube It also includes a drive device that can drive the dredge, soil collector, scrubber, blower...

Embodiment 2

[0055] The second embodiment is based on the first embodiment, and is also provided with a control unit that controls the on and off of the motor switch, which is located at both ends of the cable protection tube to detect the status of the dredge and other infrared detectors that enter and exit the cable protection tube. The control unit is electrically connected to the control unit; the control unit controls the two driving devices to alternately act according to the feedback information of the infrared detector, specifically: when the driving device I is active, the driving device II does not operate, and the infrared detector detects that the cable When the protection tube is at one end of the driving device I, the two driving devices are controlled to alternate (the driving device I does not operate, 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 cable protection pipe dredging device and method. Background technique [0002] As a trenchless construction technology, cable jacking construction technology is generally applicable in the process of cable laying in the power industry. The main process includes four processes: underground cable path exploration, pipe jacking, underground cable protection pipe penetration, and power cable laying through pipes. Among them, in the underground connection link of the cable protection pipe, the cable protection pipe (PE pipe) is forced by the underground reamer, because the cable protection pipe mouth is not tightly sealed, and the underground hard objects (stones, tiles, etc.) are scratched. It often causes some soil to enter the pipe, which is easy to cause the inside of the cable protection pipe to be blocked, which affects the next link of the power cable laying process. T...
