[0002] CPVC power pipes are usually used as cable protection pipes. This product has 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, convenient construction, etc. The product performance is much better than traditional asbestos cable pipes and ordinary PVC pipes, and it is an ideal substitute for traditional power cable protection pipes. According to the Chinese patent publication number CN218732821U, a cable protection pipe convenient for wire threading, it can be known that: in this utility model, a wire threading device is arranged inside the cable protection pipe. During the cable threading process of the cable protection pipe, one or more cables are driven by the wire threading device for rapid wire threading, and the wire threading efficiency is relatively high. In addition, multiple wire threading holes arranged at intervals on the wire threading device can separate multiple strands of cables and enable multiple strands of cables to be threaded simultaneously, without causing the cables of each strand to be wound around each other, reducing cable usage failures. Its defect is that: the balls roll on the inner wall of the cable protection pipe for a long time, and the balls will lack lubrication, and the rolling speed of the balls will become slower, affecting the wire threading effect. Moreover, no positioning device is arranged in the existing wire threading holes, and the cable will rotate randomly when the cable is pushed through the CPVC power protection pipe. Therefore, we propose a CPVC power cable protection pipe provided with a wire threading device. Summary of the Utility Model

[0020] Embodiment 1:

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution: a CPVC power cable protection pipe provided with a wire threading device, including a CPVC power protection pipe 1, a wire threading plate 2 is arranged inside the CPVC power protection pipe 1, a plurality of ball grooves 7 are arranged on the outer side wall of the wire threading plate 2, and the plurality of ball grooves 7 are arranged in a circular array on the outer side wall of the wire threading plate 2. A ball 4 is arranged in each of the plurality of ball grooves 7, and the outer side walls of the plurality of balls 4 are all in contact with the inner side wall of the CPVC power protection pipe 1. A plurality of wire threading holes 3 are arranged on the outer side wall of the wire threading plate 2, a plurality of cavities 9 are arranged inside the wire threading plate 2, a positioning component 8 is arranged in each of the plurality of cavities 9, and a lubricating component 6 is arranged inside the wire threading plate 2;

[0022] The lubricating component 6 includes an oil storage cavity 60 and an oil filling cavity 61 arranged inside the wire threading plate 2. An osmotic layer 64 is arranged on the inner side wall of the oil filling cavity 61. The osmotic layer 64 is a sponge. A plurality of oil outlet holes 62 are arranged on the inner side wall of the oil filling cavity 61, and the plurality of oil outlet holes 62 are arranged in a circular array on the inner side wall of the oil filling cavity 61. The oil outlet holes 62 are communicated with the ball grooves 7. A plurality of oil guiding ropes 63 are arranged in the oil storage cavity 60. One ends of the plurality of oil guiding ropes 63 are all located in the oil filling cavity 61. An oil filling port 10 communicated with the oil storage cavity 60 is arranged on the front side wall of the wire threading plate 2. A sealing bolt 5 is threadedly connected in the oil filling port 10. Lubricating oil is added to the oil filling cavity 61 through the oil filling port 10, and then the oil filling port 10 is sealed by the sealing bolt 5.

[0023] Please refer to Figure 5 , the positioning component 8 includes a sliding plate 81 slidably connected inside the cavity 9. A spring 80 is arranged on the top of the sliding plate 81. One end of the spring 80 is connected to the inner top of the cavity 9. An activity rod 82 is arranged at the bottom of the sliding plate 81. A positioning plate 83 is arranged inside the wire threading hole 3.
