Problems solved by technology

[0004] Many cable protection pipes constructed in the early years are inconvenient to maintain due to their long history, especially most of them are buried deep underground. Cause cable damage, and then large-scale power outages and equipment damage accidents
And after the cable protection tube is damaged, it is almost impossible to replace it as a whole

Embodiment 1

[0029] Embodiment 1: a kind of cable protection tube (see Figure 1-Figure 6 ), which includes two mutually butted protection tubes 1, the protection tube 1 is composed of an end tube head 1-1 and a tail straight tube 1-2, and the diameter of the end tube head 1-1 is larger than that of the tail The pipe diameter of the straight pipe 1-2, the pipe diameter of the end pipe head 1-1 is 21.6cm, and the pipe diameter of the tail straight pipe 1-2 is 18.8cm. The protection tube 1 is provided with two butted pipe pillows 2, and each pipe pillow 2 is provided with a semicircular pipe groove 2-1, and the joint of each pipe pillow 2 is provided with a trapezoidal pipe pillow slot 2- 2. The length L of the pipe pillow 2 is 24cm, the width W is 10cm, the height H is 12cm, the diameter R of the semicircular pipe groove 2-1 is 19cm, and the length of the long side of the trapezoidal pipe pillow slot 2-2 is 1.2cm , the length of the short side is 1.0cm, and the height is 0.8cm. Two butted ...

Embodiment 2

[0031] Embodiment 2: a kind of cable protection tube (see Figure 8 ), its structure and principle are basically the same as in Embodiment 1, the difference is that it is composed of three groups of cable protection tubes in Embodiment 1, wherein the first group of protection tubes 1 is inserted into the second group of protection tubes through its tail straight tube 1-2 The end tube head 1-1 of 1 is connected with the second group of protection tubes 1, and the second group of protection tubes 1 is inserted into the end tube head 1-1 of the third group of protection tubes 1 through its tail straight tube 1-2. The third group of protection tubes 1 are connected.

[0032] This embodiment is mainly used for laying cable protection tubes for directly buried cables.

[0033] During use, in order to ensure waterproof requirements, at this time, waterproof rubber should be clamped on both sides of the cable protection tube of the present invention, and a strong adhesive tape should...

Embodiment 3

[0034] Embodiment 3: a kind of cable protection tube (see Figure 9 ), its structure and principle are basically the same as in Embodiment 2, the difference is that it is composed of four sets of cable protection tubes in Embodiment 2 connected, and the other three faces of the pipe pillow 2 except the docking face are symmetrically arranged on the two sides and the bottom face 2 trapezoidal pipe pillow jacks 2-4, the pipe pillows 2 of the four groups of cable protection pipes are connected through the latches 2-3 in the side pipe pillow jacks 2-4.

Abstract

The present invention discloses a cable protection pipe, characterized by comprising at least one group of protection pipes (1), wherein each group of protection pipes (1) consists of two protection pipes (1) which are butted with each other, each protection pipe (1) consists of an end pipe head (1-1) and a tail straight pipe (1-2) which are connected to form the whole, the pipe diameter of the end pipe head (1-1) is greater than the pipe diameter of the tail straight pipe (1-2),the protection pipes (1) are provided with at least one group of pipe carriers (2), each group of pipe carriers (2) consists of two pipe carriers (2) which are butted with each other, each pipe carrier (2) is provided with a semicircular pipe groove (2-1), butting positions of each pipe carrier (2) are provided with trapezoid pipe carrier slots (2-2), and two pipe carriers (2) which are butted with each other are connected through inserted pins (2-3) in the pipe carrier slots (2-2). The cable protection pipe of the present invention is simple in structure, convenient to install, high in mechanical strength, and is capable of reducing enterprise cost.

Description

Technical field: [0001] The invention relates to a cable protection tube, which is widely used in the construction of power transmission and distribution projects in electric power systems, and belongs to the field technical field of power distribution maintenance. Background technique: [0002] The cable protection tube is mainly installed at the intersection of communication cables and power lines to prevent short-circuit accidents caused by disconnection of power lines, and to avoid electrification of communication cables and steel wire ropes, so as to protect cables, switches, core boards, and the whole machine from being burned out. The power line magnetic field interference also plays a certain role in isolation. With the development of the times, composite materials made of cement or other non-metallic materials are gradually replaced by FRP. Most of the cable protection tubes made of FRP can improve its corrosion resistance and life in the ground. It has a smooth sur...
