[0002] Power pipelines are pipeline facilities used to protect and accommodate power cables and wires. They play a vital role in the power system and can ensure the safety, stability and reliability of power transmission. Power pipes have the characteristics of high strength, good flexibility, high temperature resistance, corrosion resistance, flame retardancy, good insulation performance, no pollution, not easy to age, light weight, and convenient construction. They are now widely used in municipal road projects and power line projects. Power pipelines can prevent wires and cables from external mechanical damage, chemical corrosion, water immersion, etc., extend the service life of wires and cables, isolate power lines from the external environment, reduce the impact of electromagnetic fields on the surrounding environment, and also reduce the interference of external factors on power transmission. Through power pipelines, power lines can be clearly planned and arranged, which is convenient for later maintenance, inspection and troubleshooting. After the power pipeline is laid, the cables and wires can be inserted into the power pipeline; When cables and wires are being laid and threaded through pipes, the pulled cables and wires often fall on the bottom of the inner wall of the power pipe. When there are a lot of debris such as mud accumulated in the power pipe, the cables and wires that fall on the bottom of the inner wall of the power pipe will be in contact with it for a long time during threading and will be damaged by friction.

When the electric roller 303 moves, it drives the annular frame plate 301 together. When the annular frame plate 301 moves, it drives the inner built-in connecting plate 304 to move. The built-in connecting plate 304 moves and drives the annular casing 309 and the motor 306 on one side to move together. The motor 306 is started to drive the linkage rod 307 at one end to rotate.

[0022] When the present invention is operated and used, before threading, the cable and wire are first passed through the wire pulling device 2 and then fixed on the wire threading device 3. At this time, the wire threading device 3 can be placed inside the power tube 1, and the cable and wire are pulled through the wire threading device 3 to perform wiring in the power tube 1. When the wire threading device 3 starts to pull the cable and wire for wiring, the wire pulling device 2 can be sleeved and fixed on the outside of the power tube 1 to straighten the pulled cable and wire, and the cable and wire to be pulled are passed between two heavy-duty rollers 203, and the heavy-duty rollers 203 are pushed by the electric push rod 202 to clamp and squeeze the cable and wire from above and below respectively. When the heavy-duty rollers 203 perform clamping and squeezing on the cable and wire, the pressure should not be too large so that the surface of the cable and wire has slight concave marks That is, the cables and wires that need to be pulled are squeezed by two heavy-duty rollers 203 to keep the cables and wires taut and straight at all times when being pulled. When the cables and wires are pulled, the heavy-duty rollers 203 are driven to rotate, and the heavy-duty rollers 203 rotate together with the pulling of the cables and wires. At the same time, the weight of the heavy-duty rollers 203 is set to be heavier, so that when the heavy-duty rollers 203 are squeezed by the pressure clamping method, the cables and wires need a larger traction force to be pulled. By setting the weight of the heavy-duty rollers 203 to be heavier, the heavy-duty rollers 203 will not be easily pulled. When the heavy-duty rollers 203 rotate, the outer side is always in contact with the arc scraper 205, and the arc scraper 205 scrapes the outer surface of the rotating heavy-duty rollers 203. In addition to cleaning, when the heavy roller 203 moves in the direction of the cable and wire to clamp the cable and wire, the vertical baffle 207 on one side of the concave plate 204 moves with the concave plate 204 through the curved connecting rod 206. When the vertical baffle 207 moves, the cable and wire are sandwiched in the middle and aligned for sliding limit. After the cable and wire pass through the wire pulling device 2, they are fixed on the locking ring 305. The electric roller 303 drives the threading device 3 as a whole to move and wire in the power pipe 1. When the electric roller 303 moves, it drives the annular frame plate 301 together. When the annular frame plate 301 moves, it drives the inner built-in connecting plate 304 to move. The built-in connecting plate 304 moves and drives the annular casing 309 and the motor 306 on one side to move together, and the motor 3 is started. 06 drives the linkage rod 307 at one end to rotate. When the linkage rod 307 rotates, it drives the crushing mechanism 308 at one end and the spiral scraper 310 on the outside to rotate. When the crushing mechanism 308 rotates, it crushes and cleans the position where the electric roller 303 inside the power pipe 1 is about to move. When the accumulated mud cleaned by the crushing mechanism 308 is large, it will overflow on the side close to the spiral scraper 310. When the spiral scraper 310 rotates, it stirs the accumulated mud overflowed from the crushing mechanism 308. When the spiral scraper 310 rotates, it pushes the accumulated mud to move into the inner oblique ring plate 311 through the spiral rotation. The cleaned accumulated mud continuously moves into the inner oblique ring plate 311 and passes through the inner oblique ring plate 311 to be discharged to the other side of the annular frame plate 301.By setting the outer diameter of the inner oblique ring plate 311 to be consistent with the inner diameter of the power pipe 1, the mud pushed by the spiral scraper 310 can enter the inner oblique ring plate 311, and the annular casing 309 sleeved on the linkage rod 307 fully wraps the motor 306. When the linkage rod 307 rotates, it drives the three-rod frame 3085 at one end to rotate. When the three-rod frame 3085 rotates, it drives the outer fan-shaped baffle 3086 and the annular scraper 3081 to rotate together. When the annular scraper 3081 rotates, it drives the side round rod 3082 on one side to rotate together. When the side round rod 3082 rotates, it drives the outer sharp thorn block 3083 to rotate together with the annular scraper 3081. When the sharp thorn block 3083 rotates, the mud accumulated inside the power pipe 1 is broken and cleaned. 3, the annular scraper 3081 is driven to move together. When the annular scraper 3081 moves, the conical thorn head 3084 at one end is driven to move together through the side round rod 3082. When the conical thorn head 3084 moves, the mud blocks with a large coverage area in the power pipe 1 are crushed by top punching. When the annular scraper 3081 moves, it is always in contact with the inner wall of the power pipe 1. The moving annular scraper 3081 slides and scrapes the inner wall of the power pipe 1. More and more mud is gradually accumulated on the side of the annular scraper 3081 close to the side round rod 3082. When too much mud is cleaned up, it will overflow to the spiral scraper 310 area through the material passing hole 3087. By setting the material passing hole 3087 with a small aperture, it is convenient for mud to pass through and block the mud blocks that are not completely crushed.
