Description

Submersible cable synthetic resin protection tube {A protected tube of a cables for underground}

The present invention relates to a cable synthetic resin protective tube for embedding, in particular, the extrusion of the protective tube to a certain shape by using waste vinyl as the main raw material, so that the cable through hole is formed in the protective tube according to the diameter of the cable embedded in the basement, In addition, by extruding the shape of the protective tube into a circle, triangular, square, and polygonal shape, it is possible to protect the natural environment by using waste vinyl to discard the main composition of the protective tube, and also when excavation due to other buried work The present invention relates to a cable synthetic resin protective tube for preventing accidental damage to a cable, thereby preventing safety accidents such as communication failures.

In general, a cable embedded in the basement or the like is generally a means of protecting the cable so that a synthetic resin coating such as synthetic rubber or polyethylene is coated on the circumferential surface of the cable so that moisture can penetrate into the cable. Oxidation is prevented.

In this way, the conventional cable can be prevented and protected from various damages from the outside by the sheath coated on the outer circumferential surface.However, after the cable is buried underground or undersea, the cable itself is There is an unreasonable point that it is difficult to maintain the position and the cable is damaged due to carelessness during excavation due to other burial work.

The present invention is to solve the above problems, the present invention constitutes a protective tube that can prevent the flow by the external action when buried, and also a cable that can be maintained by passing the cable through the protective tube By extrusion molding to form through-holes, the production of protective tubes that can protect cables can be simplified, resulting in lower production costs. Especially, cable protective tubes protect cables that are buried underground. As it does not need to be used as a high-quality synthetic resin, the synthetic resin, which is the main composition, is collected by recycling waste vinyl discarded in rural areas and recycled as raw materials, thereby making the cable synthetic resin for laying a cable cheaper. I want to provide a shelter.

The present invention consists of an outward flange which radially protrudes on the outer circumferential surface of the cable protection tube, a thin cable passage through which the cable can be stored and stored inside, and a relatively thick cable or a composite cable penetrates the inner central portion of the protection tube. It is achieved by having a thick cable path that can be stored and formed in a triangular or square shape so as to prevent the cable protection tube from flowing when it is buried instead of an outward flange on the outer circumferential surface.

Therefore, the present invention is buried in the basement by radially forming an outward flange on the outer circumferential surface of the cable sheath, or when buried in the seabed, it is buried so that it can be securely fixed to the strata or the seabed. Characterized in that can be prevented.

It is an object of the present invention to provide a cable protecting tube which can be freely selected and inserted into any cable having a different thickness, so as to be provided with a plurality of thick and thin cable passages inside the cable protecting tube.

Hereinafter, a preferred embodiment of the buried cable protective tube according to the present invention will be described in detail based on the accompanying drawings.

1 and 2 are a perspective view and a front view showing a temporary example of the buried cable synthetic resin protective tube according to the present invention, the protective tube is protruding radially outward on the outer circumferential surface of the round-shaped round tube 1 A plurality of outward flanges 2 are formed.

The outward flange 2 serves to prevent the flow of the cable 10 and the cable body 1 when the pipe body 1 is buried underground as shown in Figs. 6 and 7 to maintain the embedding position. .

In the inner central portion of the tubular body 1, one cable passage 3 in which a relatively thick passage is formed in the longitudinal direction, and a plurality of relatively narrow passages in the longitudinal direction are formed in the longitudinal direction of the outer side of the cable passage 3. It consists of a narrow cable passage (4).

The size of the cable passages (3) and (4) is not limited to that only the center and the passage around the periphery should be formed by a small hole, it can also be designed and manufactured according to the diameter of the cable to be embedded.

In addition, as shown in FIG. 3, the outer periphery of the tubular body 1 may be omitted, and only the cable passages 3 and 4 through which the cable 10 may be formed may be formed. It can be used for the purpose of fixing the cable to the structure which is thin or not for underground laying.

In addition, even when the cable protection tube itself is not formed in the shape of a tubular body 1, and is formed as a triangular protective tube 5 as shown in FIG. 4 or a quadrangular protective tube 6 as shown in FIG. If the triangle (5) or the quadrilateral (6) itself is also inhibited flow in the strata, it is possible to prevent the closed end to flow arbitrarily by the external action.

In addition, the present invention, as shown in Figures 8a and 8b can be assembled by dividing the tubular body (2) into one or a plurality of extrusion, and also a clamp that can be fixed to the divided pipe bodies (2) (not shown) ) May be assembled.

The split pipe 2 allows the split pipe 2 to be installed on an element element while protecting the cable 10 using the pipe 1 as described above, thereby replacing and repairing the cable 10. There is an easy advantage.

In particular, it may be provided so as to protect the cable 10 by configuring only the split pipe (2).

Since the above-described tubular bodies 2 are formed by extrusion molding, they can be cut and installed according to the design of the length of the cable and the formation of the terminal portion of the cable, and also a simple regeneration operation in which waste vinyl is melted to add a predetermined composition. As can be produced by, there is an advantage that can significantly reduce the production cost.

According to the cable synthetic resin protective tube for embedding according to the present invention as described above, a cable that can be made to penetrate and maintain the protective tube to prevent the flow by the external action at the time of the buried By extrusion molding to form through-holes, the production of protective tubes that can protect cables can be simplified, resulting in lower production costs. Especially, cable protective tubes protect cables that are buried underground. As it does not have to be used as a good synthetic resin, the synthetic resin, which is the main composition, is recycled as raw materials by collecting waste vinyl discarded in rural areas, thereby making it possible to reduce the manufacturing cost of the one-layer cable protective tube.
