Abstract
The utility model relates to technical field of electric wires and cables; particularly relate to lever apparatus on a kind of power cable; comprise support anchor ear, protection tube, flared tube and curved steel pipe; protection tube is fixed on electric pole or external wall by support anchor ear; protection tube upper port is bell mouth shape, and lower port is connected with curved steel pipe by flared tube.The beneficial effects of the utility model are, lever apparatus on the utility model power cable, by upper lever apparatus by power cable under distribution facility electric pole or external wall lay and draw, specification is installed, and firm cable, greatly reduces the generation of security incident; Go up steel pipe used in lever apparatus simultaneously and, all through hot galvanizing process, improve anticorrosive property, greatly strengthen the useful life of lever apparatus on this.
Description
Technical field
The utility model relates to technical field of electric wires and cables, particularly relates to lever apparatus on a kind of power cable.
Background technology
Along with the development of society, the use of cable gets more and more, the field of application is also more and more extensive, especially in modern power systems construction and transformation, power cable is used widely, simultaneously also more and more higher to the requirement of cable type and performance in the application, how do not affecting on the structure of distribution facility electric pole or external wall, load and aseptic condition basis, by safe, efficient for power cable lay draw under be a difficult problem of power engineering construction always.At present; in prior art, under power cable lays draw mainly through power cable upper boom, and the upper boom of power cable protection great majority are coating steel pipes or directly outside exposed; useful life is lower; and fix insecure or protect unreal, when using in some particular surroundings, intensity is too low; technique is lack of standardization and inadequate to the protection of cable; easily cause the damage of external force, cause power failure, affect the normal use of cable.
Utility model content
The technical problems to be solved in the utility model is: short, fixing insecure for useful life in order to solve lever apparatus on current power cable; mounting process is lack of standardization and protect insufficient strength; easily cause the problem of security incident, the utility model provides lever apparatus on a kind of power cable to solve the problems referred to above.
The utility model solves the technical scheme that its technical problem adopts: lever apparatus on a kind of power cable; comprise support anchor ear, protection tube, flared tube and curved steel pipe; described protection tube is fixed on electric pole or external wall by support anchor ear; described protection tube upper port is bell mouth shape, and lower port is connected with curved steel pipe by flared tube.
For the ease of imbedding underground, keep the steadiness of protection tube, flared tube and curved fastener for connection, described protection tube lower port polishes smooth and forms integrative-structure with flared tube, curved steel pipe.
In order to improve the corrosion resistance of parts surface, described formed integrative-structure external heat is coated with zinc protective layer.
For the ease of installing, curved steel pipe is arranged on electric pole side or external wall underground, and after thorough with brick, firmly, described curved steel pipe is arranged on underground, and its overbending direction is towards the cable trough of underground, and end extends in the cable trough of underground for filling yellow sand or weak soil compacting.
As preferably, the bending of described curved steel pipe is arc-shaped, and the central angle alpha of described circular arc is 45 °.
In order to improve the corrosion resistance on support anchor ear surface, described support anchor ear external heat is coated with zinc protective layer.
The beneficial effects of the utility model are, lever apparatus on the utility model power cable, by upper lever apparatus by power cable under distribution facility electric pole or external wall lay and draw, specification is installed, and firm cable, greatly reduces the generation of security incident; Go up steel pipe used in lever apparatus simultaneously and, all through hot galvanizing process, improve anticorrosive property, greatly strengthen the useful life of lever apparatus on this.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of lever apparatus on the utility model power cable.
Fig. 2 is flared tube and curved steel-tube construction schematic diagram in Fig. 1.
In figure, 1, support anchor ear, 2, protection tube, 3, flared tube, 4, curved steel pipe, 5, electric pole, 6, cable trough.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As Fig. 1, shown in 2, lever apparatus on the utility model power cable, comprise support anchor ear 1, protection tube 2, flared tube 3 and curved steel pipe 4, protection tube 2 is fixed on electric pole 5 or external wall by support anchor ear 1, protection tube 2 upper port is bell mouth shape, lower port is connected with curved steel pipe 4 by flared tube 3, protection tube 2 lower port polishes smooth and flared tube 3, curved steel pipe 4 forms integrative-structure, the integrative-structure external heat formed is coated with zinc protective layer, curved steel pipe 4 is arranged on underground, its overbending direction is towards the cable trough 6 of underground, and end extends in the cable trough 6 of underground, the bending of curved steel pipe 4 is arc-shaped, the central angle alpha of circular arc is 45 °, support anchor ear 1 external heat is coated with zinc protective layer.
Power cable is laid by protection tube 2, flared tube 3 and curved steel pipe 4 according to this along electric pole 5 or external wall edge and draws downward-extension in below ground or cable trough 6; and by the support anchor ear 1 of suitable size, protection tube 2 is fixed on electric pole 5 or external wall; further enhancing steadiness, improve protection intensity and coefficient of safety.Simultaneously because steel pipe used in upper lever apparatus is all through hot galvanizing process, define layer protective layer, its antiseptic power is stronger; adhesive force and the hardness of zinc coat are better; with general zinc-plated compared with, run into wet environment and be not easy to come off, greatly strengthen the useful life of lever apparatus on this.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
