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
Technical field:
The utility model relates to cable protective sleeve, particularly a kind of at cable from the underground cable protective sleeve that uses that passes.
Background technology:
The problem that exposes of city transmission line for a change, many cities have adopted underground cable to transmit electricity.Pass from underground at cable, the cable that directly will have insulation property mostly directly passes from underground.Because cable directly passes from underground,, all can cause the damage of cable, safety thereby influence is transmitted electricity when the vehicle collision cable place of passing or when artificially cutting cable with knife.
Summary of the invention:
The purpose of this utility model is: provide a kind of underground cable of can effectively protecting to pass the cable protective sleeve at place.The utility model is achieved through the following technical solutions:
A kind of cable protective sleeve; The internal layer protective sleeve that outer layer protective sleeve that protective sleeve is made by hard material and insulating material are made is formed.Protect cable at cable from underground passing,,, can effectively protect cable, guarantee transmission of electricity safety because protective sleeve has good resistance to compression and anti-cutting performance when the vehicle collision cable place of passing or when artificially cutting cable with knife with protective sleeve.
In the utility model, described cable protective sleeve is formed by two unit constructions with cavity, connects by fixture between two parts.Two parts with cavity can be pulled down or connect easily, make the protective sleeve installation and removal more convenient, are beneficial to the installation of protective sleeve.Certainly, also can adopt hinge type to flexibly connect by an end between two parts, the other end adopts fixture to connect.
In the utility model, described outer layer protective sleeve is the iron and steel cover, and outer layer protective sleeve and internal layer protective sleeve are combined into one.Outer layer protective sleeve adopts the iron and steel cover, and it has good resistance to compression and anti-cutting performance; The protective sleeve that internal layer is made by insulating material can improve insulation property, makes transmission of electricity safer.
In the utility model, the cross sectional shape of described protective sleeve becomes regular hexagon.Orthohexagonal cross sectional shape can improve the compressive property of protective sleeve.Certainly, cross sectional shape of the present utility model also can adopt shapes such as circle, ellipse, regular polygon.
In the utility model, described two parts are provided with the flange that is used for mounting fixing parts in the junction.Be convenient to the installation of fixture.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model schematic cross-section.
Embodiment:
In conjunction with Fig. 1, shown in Figure 2: the internal layer protective sleeve 2 that outer layer protective sleeve 1 that the cable protective sleeve of present embodiment is made by hard material and insulating material are made is formed.Outer layer protective sleeve 1 is the iron and steel cover, and outer layer protective sleeve 1 and internal layer protective sleeve 2 are combined into one.Cable protective sleeve is formed by two unit constructions with cavity, connects by fixture 3 between two parts.Two parts are provided with the flange 4 that is used for mounting fixing parts in the junction.The cross sectional shape of protective sleeve becomes regular hexagon.Fixture 3 can adopt such as screw, bolt class fixture.Fixture preferably adopts has the antitheft fixture that revolves structure.
From the underground protective sleeve protection cable that uses present embodiment that passes,, can effectively protect cable at cable, guarantee transmission of electricity safety because protective sleeve has good resistance to compression and anti-cutting performance.And the installation of protective sleeve is also very convenient.
