Problems solved by technology

[0005] 1. The heat insulation effect is poor, which affects the service life of the internal cables;
[0006] 2. Because the cable protection tubes are often used in multiple bundles, the outer circle structure makes it difficult to locate the relative position of the cable protection tubes, and it is easy to roll during installation, making installation difficult;
[0007] 3. The single-layer ring structure has low compressive strength. When the cable is routed underground, it is easy to cause damage to the pipeline, thus affecting the normal use of the cable.

Embodiment 1

[0032] Such as figure 1 As shown, the special-shaped communication cable protection tube includes an inner pipe 100, an outer pipe 200 and a support rib 300; the outer pipe 200 is composed of 8 outer pipe ribs 201, and the 8 outer pipe ribs 201 are surrounded by a regular octagon; The middle part of the outer pipe rib 201 is connected with the inner pipe 100; both ends of the outer pipe rib 201 are connected with support ribs 300;

[0033] Therefore, there are 8 support ribs 300 in the special-shaped communication cable protection tube, and they are in an equiangular circular array. The included angle between the adjacent support ribs 300 is 45°, which can well disperse the external force, so that the protection tube is evenly compressed.

[0034] The inner pipe 100 is a hollow cylinder; the inner pipe 100 , the outer pipe 200 and the support ribs 300 enclose a hollow and triangular gap cavity 400 . The gap cavity 400 not only plays a good role in heat insulation, but also r...

[0038] Such as figure 2 As shown, the special-shaped communication cable protection tube includes an inner pipe 100, an outer pipe 200 and a support rib 300; the outer pipe 200 is composed of 8 outer pipe ribs 201, and the 8 outer pipe ribs 201 are surrounded by a regular octagon; The middle part of the outer pipe rib 201 is connected with the inner pipe 100; both ends of the outer pipe rib 201 are connected with support ribs 300;

[0039] The inner pipe 100 is a hollow cylinder; the inner pipe 100 , the outer pipe 200 and the support ribs 300 enclose a hollow and triangular gap cavity 400 .

[0040] The gap cavity 400 includes a short right-angled side 401, a long right-angled side 402 and a hypotenuse 403; the short right-angled side 401 is adjacent to the support rib 300; the long right-angled side 402 is adjacent to the inner pipe 100, and the length The right-angled side 402 is perpendicular to the radius of the inner pipe 100 ; the hypotenuse 403 is adjacent to the out...

Embodiment 3

[0043] Such as image 3 As shown, the special-shaped communication cable protection tube includes an inner pipe 100, an outer pipe 200 and a support rib 300; the outer pipe 200 is composed of 8 outer pipe ribs 201, and the 8 outer pipe ribs 201 are surrounded by a regular octagon; The middle part of the outer pipe rib 201 is connected with the inner pipe 100; both ends of the outer pipe rib 201 are connected with support ribs 300;

[0044] The inner pipe 100 is composed of 16 inner pipe ribs 101, and the 16 inner pipe ribs 101 are surrounded by a hollow regular hexagon; one end of the inner pipe rib 101 is connected to the support rib 300, and the other end is connected to the outer The middle part of the tube rib 201 ; the inner tube rib 101 , the outer tube rib 201 and the support rib 300 enclose a hollow and triangular gap cavity 400 .

[0045] The gap cavity 400 includes a short right-angled side 401, a long right-angled side 402 and a hypotenuse 403; the short right-angl...

Abstract

The invention discloses a special-shaped communication cable protective pipe and belongs to the technical field of wire conduits. The protective pipe comprises an inner pipeline, an outer pipeline and supporting ribs. The outer pipeline is composed of eight outer pipe ribs, and the eight outer pipe ribs form an octagon. The middles of the outer pipe ribs are connected with the inner pipeline. The two ends of each outer pipe rib are connected with the corresponding supporting ribs. The supporting ribs are arranged in the radial direction, and the inner sides of the supporting ribs are connected with the inner pipeline. The inner pipeline and outer pipeline double-layer structure is adopted for the special-shaped communication cable protective pipe, the supporting ribs are arranged in the radial direction between the inner pipeline and the outer pipeline, and in this way, the protective pipe improves compressive strength and bending-resistive performance, and is firm, durable and good in impact-resistive performance. The supporting ribs are arranged between the inner pipeline and the outer pipeline, and gaps are formed in the two sides of each supporting rib. Because air is a hot poor conductor, inside and outside temperature transfer can be well isolated through the special-shaped communication cable protective pipe, a cable is prevented from being affected by outside temperature fluctuations, signal transmission is better facilitated, and meanwhile the service life of the cable is prolonged.

Description

technical field [0001] The invention belongs to the technical field of conduits, and in particular relates to a special-shaped communication cable protection tube. Background technique [0002] With the transformation of urban power grids and the advancement of communication services, cable protection tubes will be widely used to prevent cable damage. Traditional cable protection pipes include steel pipes, cement pipes and plastic pipes. [0003] Steel pipes and cement pipes are inconvenient to install because of their heavy weight. When the cables are overhead, the load will increase, endangering the safety of the brackets or bridges. [0004] Plastic pipes, such as the cable protection pipe described in Chinese Patent Publication No. 103439778A, the pipe body is a hollow cylinder, and its disadvantages are as follows: [0005] 1. The heat insulation effect is poor, which affects the service life of the internal cables; [0006] 2. Because the cable protection tubes are ...
