MPP electric power tube

Abstract

The invention discloses an MPP electric power pipe, which comprises a pipe body, a positioning block is arranged on the top of the inner wall of the pipe body, balls are inlaid on the side of the positioning block away from the pipe body, and the bottom of the inner wall of the pipe body is fixedly connected with A ring block, and the top of the ring block is fixedly equipped with a telescopic rod, and the end of the telescopic rod away from the ring block is fixedly connected with a U-shaped bracket, the inside of the U-shaped bracket is provided with a buffer pad, and the pipe body includes an inner tube and outer tube. The MPP power pipe, through the improvement of the pipe body, improves the firmness of the pipe body itself, effectively protects the cable, and the setting of the buffer device not only achieves the protection effect of the pipe body when the cable is pulled, but also It also achieves the protective effect on the cable; the coordinated use of positioning blocks, balls, ring blocks, telescopic rods, U-shaped brackets and buffer pads further achieves the protective effect on the cable when pulling the cable, avoiding the Damage to cables.

Description

technical field [0001] The invention relates to the technical field of pipes, in particular to an MPP power pipe. Background technique [0002] MPP power pipes are divided into trench type and non-excavation type. MPP non-excavation pipe is also called MPP jacking pipe or tola pipe. MPP power pipe uses modified polypropylene as the main raw material. It has the characteristics of high temperature resistance and external pressure resistance, and is suitable for high-voltage transmission lines and cables above 10KV. The existing MPP power tubes have poor heat dissipation performance and are not easy to maintain. [0003] Chinese open patent, patent number: CN 205016979 U, once proposed a kind of MPP power pipe, including the pipe body made of MMP, in the channel of the pipe body, there is an axially arranged arc-shaped splint, and the outer arc of the arc-shaped splint Between the pipe body and the axially spaced and uniformly distributed elastic support assembly, the elast...

AI Technical Summary

Problems solved by technology

The power tube has the effects of heat dissipation, cable aging prevention and compression resistance, but this patent still has certain defects. For example, when the cable is pulled, it is easy to cause damage to the power tube, and it cannot completely achieve the effect of strong firmness. It is easy to cause damage to the surface of the cable when pulling the cable
