AI Technical Summary

Technical Problem

Existing MPP power pipes are laborious to install protective sleeves and are easily damaged by compression after being buried underground, lacking effective pressure-resistant structures and buffer mechanisms.

Method used

A protective sleeve is fitted onto the outer surface of the power conduit body, and two sets of parallel anti-pressure mechanisms are set up, including a mounting plate, a buffer box, a vertical rod, a sliding plate, a spring, and a U-shaped anti-pressure plate, combined with ball bearings and buffer rings to reduce friction and buffer external pressure.

Benefits of technology

This technology saves time and effort when installing protective sleeves on power conduits, improves their compressive strength after burial, prevents damage to power conduits, and ensures the stability of power transmission.

Abstract

The utility model discloses a pressure-resistant MPP electric power pipe, relates to the technical field of electric power pipes, and aims to solve the problems that the electric power pipe is strenuous to install a protective sleeve and the electric power pipe is easy to be extruded and damaged after being buried, the pressure-resistant MPP electric power pipe comprises an electric power pipe body, and the outer surface of the electric power pipe body is sleeved with the protective sleeve. Two groups of compression-resistant mechanisms distributed in parallel are arranged on the outer surface of the protective sleeve; through cooperation of the U-shaped pressure-resistant plate, the sliding plate and the spring, external pressure borne by the U-shaped pressure-resistant plate is buffered, the external pressure is prevented from directly acting on the electric power pipe body, and the pipe body is prevented from being damaged; the friction force between the outer surface of the buffer ring and the inner surface of the protective sleeve is reduced, so that the electric power pipe body can be easily pushed into the protective sleeve, and the problems that the electric power pipe is strenuous when the protective sleeve is installed and the electric power pipe is easily extruded and damaged after being buried are effectively solved.
