CN2819569Y - Cable protective cover - Google Patents

Abstract

The utility model relates to a cable protective cover. The protective cover is composed of an outer layer protective cover which is made of hard material and an inner layer protective cover which is made of insulation material. The cable is protected by the protective cover on the part where the cable is penetrated from underground; when a vehicle impacts the part where the cable is penetrated or the cable is artificially cut by a knife, because the protective cover has the favorable compression resistant and cut resistant performances, the cable can be effectively protected and the power transmission safety can be ensured. The cable protective cover is formed by the combination of two parts with concave cavities, and the two parts are connected by a fixed part. The two parts with the concave cavities can be removed and connected conveniently, which causes the assembly and the disassembly of the protective cover to be more convenient and which is helpful for the assembly of the protective cover.

Description

cable protector

Technical field:

The utility model relates to a cable protective cover, in particular to a cable protective cover used at the place where the cable passes through the ground.

Background technique:

In order to change the problem of exposed urban transmission lines, many cities have adopted underground cables for power transmission. Where the cable passes through the ground, most of the cables with insulating properties are directly passed through the ground. Because the cable directly passes through the ground, when the vehicle collides with the cable or cuts the cable artificially with a knife, the cable will be damaged, thereby affecting the safety of power transmission.

Invention content:

The purpose of the utility model is to provide a cable protective cover which can effectively protect the place where underground cables pass through. The utility model is achieved through the following technical solutions:

A cable protective sheath; the sheath consists of an outer sheath made of hard material and an inner sheath made of insulating material. Use a protective sheath to protect the cable where the cable passes through the ground. When the vehicle collides with the cable or cuts the cable with a knife, the protective sheath has good compression resistance and anti-cutting performance, which can effectively protect the cable and ensure the safety of power transmission.

In the utility model, the cable protection sheath is composed of two parts with concave cavities, and the two parts are connected by a fixing piece. The two parts with concave cavities can be easily disassembled or connected, which makes the installation and disassembly of the protective cover more convenient and facilitates the installation of the protective cover. Of course, one end of the two parts can also be connected by a hinge type, and the other end can be connected by a fixing piece.

In the utility model, the outer protective sheath is a steel sheath, and the outer protective sheath and the inner protective sheath are combined into one. The outer protective sheath is made of steel, which has good pressure resistance and cut resistance; the inner protective sheath made of insulating material can improve the insulation performance and make power transmission safer.

In the present utility model, the cross-sectional shape of the protective sleeve is a regular hexagon. The cross-sectional shape of regular hexagon can improve the compressive performance of the protective sleeve. Of course, the cross-sectional shape of the present utility model can also adopt shapes such as circle, ellipse, and regular polygon.

In the present utility model, the two parts are provided with flanges for installing the fixing parts at the joints. Facilitate the installation of fixtures.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Fig. 2 is a schematic cross-sectional view of the utility model.

Detailed ways:

As shown in Fig. 1 and Fig. 2: the cable protective sheath of this embodiment is composed of an outer protective sheath 1 made of hard material and an inner protective sheath 2 made of insulating material. The outer protective sheath 1 is a steel sheath, and the outer protective sheath 1 and the inner protective sheath 2 are combined into one. The cable protection sheath is composed of two parts with concave cavities, and the two parts are connected by a fixing part 3 . The two parts are provided with a flanging 4 for installing the fixing part at the joint. The cross-sectional shape of the protective cover is a regular hexagon. The fixing member 3 can adopt fixing members such as screws and bolts. The fixing part is preferably a fixing part with an anti-theft rotation structure.

The protective sheath of this embodiment is used to protect the cable where the cable goes out of the ground. Since the protective sheath has good compression resistance and anti-cutting performance, it can effectively protect the cable and ensure the safety of power transmission. And the installation of the protective cover is also very convenient.
