Fixing structure for detachable cable protection pipe

Abstract

The invention discloses a fixing structure for a detachable cable protection pipe, including a holt hoop iron I corresponding to a pole and towel pair. One end of the holt hoop iron is provided with an extension section. A cable protection pipe body is arranged at one side of the extension section. With the adoption of cooperation between the arc clamp loop and the extension section, the cable protection pipe body is tightly clamped. The fixing structure subversively changes the overall pipe-shaped structure of the original cable protection pipe, and the cable protection pipe is designed to have the detachable structure by a mode that one divides into two, so that in the installation or the later replacement process, the efficiency is greatly improved, and the cost is reduced. The fixing structure is easy to manufacture and strong in practicality.

Description

technical field [0001] The invention relates to the technical field of cable protection, in particular to a fixing structure for a detachable cable protection tube. Background technique [0002] Throughout the various voltage levels of the power system, cables have been widely used due to their unique advantages in special environments. They play an important role as "bridges and tunnels" in the transmission and distribution lines that undertake power transmission. In today's developed world, limited land resources have become more precious. In many cases, the application of cables has become the only choice for power lines. Most power cables include cable parts. However, in order to consider the power lines themselves and their impact on the external environment For safety reasons, cable protection tubes are installed outside the cables when installing underground cable lines, and most cable protection tubes are made of integral galvanized steel pipes of various specificati...

[0002] Throughout the various voltage levels of the power system, cables have been widely used due to their unique advantages in special environments. They play an important role as "bridges and tunnels" in the transmission and distribution lines that undertake power transmission. In today's developed world, limited land resources have become more precious. In many cases, the application of cables has become the only choice for power lines. Most power cables include cable parts. However, in order to consider the power lines themselves and their impact on the external environment For safety reasons, cable protection tubes are installed outside the cables when installing underground cable lines, and most cable protection tubes are made of integral galvanized steel pipes of various specifications. The problem is that the current design of power lines has a long service life It can be said that the cables of power lines exist as "permanent" facilities in the environment of substations, main blocks in cities and passing through specific buildings, and the service life of the cable protection tubes is far less than the service life of the cables. After 6 to 10 years of service, many cable protection tubes have different degrees of corrosion and aging, which brings great hidden dangers to the personal safety of the first-level environment of the power line itself. Take out the rusted and aging old cable head, and then insert a new cable protection tube from the cable head. This process is very cumbersome, and it will inevitably cause damage and influence to the cable head and the cable itself to varying degrees.
