Description
Technical Field
The utility model belongs to the technical field of power transmission lines, relates to a bird damage prevention device for the power transmission lines, and particularly relates to a telescopic bird thorn prevention device for a power transmission tower.
Background
In recent years, with the improvement of ecological environment and the enhancement of protection consciousness of people on wild animals, birds move more frequently, and the number of faults of the overhead transmission line caused by the bird movement is also obviously increased. The bird trouble problem of the overhead transmission line has the characteristics of obvious seasonality, multiple times, strong burstiness and the like. According to the bird-involved fault risk distribution diagram, the power department needs to configure a corresponding bird damage prevention device for the overhead power transmission line bundle.
The bird-proof thorn is a common bird damage prevention device for the power transmission line, has the advantages of low cost and convenient installation, can prevent birds from inhabiting the upper part of a tower provided with the bird-proof thorn, and has a certain bird-proof effect. However, at the present stage, bird spikes are difficult to install on the cross arm right above the side phase suspension insulator of the door-shaped linear cement pole due to the special structure, and the bird spikes are inconvenient to install on the cross arm above the insulator of a part of steel pipe poles, so that the bird spikes cannot be installed right above the insulator, and therefore, the pole insulator of the type has a protection leak, and birds are easy to stay in the protection blank to discharge feces and nest, so that bird-related faults are caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art, provides a telescopic bird-preventing thorn for a transmission tower and solves the problem of bird-related faults caused by the fact that the bird-preventing thorn cannot be arranged right above an insulator.
The utility model solves the technical problems in the prior art by adopting the following technical scheme:
the utility model provides a bird thorn is prevented to retractable for transmission tower, includes mounting fixture, telescoping device and prevents the bird thorn, mounting fixture installs on the flange of shaft tower cross arm, the one end of telescoping device is installed on mounting fixture, prevent that the bird thorn is installed perpendicularly at the other end of telescoping device.
And, telescoping device includes scalable knob and telescopic bracket, the one end of scalable knob is connected with mounting fixture, the other end of scalable knob links together with telescopic bracket's one end, telescopic bracket's the other end with prevent that the bird thorn is installed together.
The utility model has the advantages and positive effects that:
the anti-bird thorn device is reasonable in design, is arranged at a cross arm flange of a tower, the position of the anti-bird thorn at one end of the telescopic bracket is adjusted by extending or shortening the telescopic bracket, the anti-bird thorn is positioned right above the insulator, birds are prevented from staying and nesting above the insulator, the protection blank spots can be effectively eliminated, the requirement of the anti-bird thorn protection range is met, the anti-bird thorn device has the characteristics of simple structure, safety, effectiveness, convenience in use and the like, the tripping of an overhead transmission line caused by bird damage can be effectively reduced, and the safe and stable operation of the transmission line is guaranteed.
Drawings
FIG. 1 is a block diagram of an anti-bird spike component of the present invention;
in the figure, 1-a fixed clamp, 2-a telescopic knob, 3-a telescopic bracket, 4-an anti-bird thorn, 5-a tower cross arm and 6-an insulator.
Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The utility model provides a telescopic prevents bird thorn for transmission tower, includes mounting fixture 1, scalable knob 2, telescopic bracket 3 and prevents bird thorn 4, mounting fixture installs on the flange of shaft tower cross arm 5, realizes the fixed function of whole bird thorn of preventing. The telescopic knob is installed on the outer side of the fixing clamp, one end of the telescopic support is installed together with the telescopic knob, and the other end of the telescopic support is installed together with the bird-preventing stabs.
In an overhead transmission line, a tower cross arm is installed on a tower through a flange, and an insulator 6 is installed below the tower cross arm to realize a wire fixing function. Therefore, when the telescopic rotary knob is rotated, the telescopic support can be controlled to extend or contract. The telescopic support can be transversely telescopic above the tower under the control of the telescopic knob, so that the position of the bird-preventing stabs on the cross arm of the tower is adjusted, and finally the bird-preventing stabs are located right above the insulator. The bird-proof thorn is vertically arranged at one end of the telescopic bracket, can effectively prevent birds from staying and nesting and effectively protect the insulator below the bird-proof thorn. Because the anti-bird thorn is positioned right above the insulator, the protection blank point can be effectively eliminated, and the requirement of the anti-bird thorn protection range is met.
It should be emphasized that the embodiments described herein are illustrative rather than restrictive, and thus the present invention is not limited to the embodiments described in the detailed description, but also includes other embodiments that can be derived from the technical solutions of the present invention by those skilled in the art.
