Description

A kind of bird-proof device

Technical field

This utility model relates to scarecrow device field, particularly relates to a kind of bird-proof device.

Background technology

Along with the arriving in summer, the activity such as nest of substantial amounts of birds easily causes electric power transmission line to take place frequently large-area power-cuts Accident.Use effective bird dispelling measure, prevent birds activity from causing transmission line malfunction, ensure grid power transmission circuit safe, Stable operation is a critically important job of power department.

Birds are nested and can cause transformer station's phase fault, and extracing bird's nest has two kinds of methods: method one, find making an inspection tour After bird's nest, formulate ad hoc inspection and repair plan, have a power failure and extract bird's nest.Cause result: in birds easy nests season, frequently make an inspection tour, frequently Have a power failure, have a strong impact on power supply reliability.Method two, finding after bird's nest, using charged excision bird's nest.Cause result: this kind of side There is limitation in method, this kind of method is relatively big by regional impact, and some region, shaft tower place, band electric car can not arrive.

Refering to shown in Fig. 1, the position that bird's nest is set up is usually located at the intersection of cross-arm 4 and line club body 5, i.e. dotted line in figure Circle position.There is bigger space between M ferrum 3 and cross-arm 4, between anchor ear 1, cross-arm 4 and line club body 5, also form space, this The space of two positions causes birds to be had ready conditions nest.Support insulator 2 is positioned on cross-arm 4.

Existing Wind bird scaring device, its principle is to stop birds to place branch in the range of blade, also by rotating vane It it is a kind of method intercepting space.Owing to anti-bird windmill is high to the requirement of natural environment, it is necessary to just can rotate in windy day Reach the effect of anti-bird, bird dispelling.Provide an auxiliary magnet even in the case of there is no wind bird nest, it is easier to put Put branch.Owing to anti-bird windmill uses of long duration, birds have been already adapted to the anti-bird principle of anti-bird windmill, still can equipped with Set up bird's nest on the shaft tower of anti-bird windmill, can not meet present running environment.

Summary of the invention

This utility model embodiment provides a kind of bird-proof device, there are birds to existing anti-bird in order to solving in prior art The problem that windmill still can set up bird's nest at shaft tower after adapting to.

This utility model embodiment provides a kind of bird-proof device, and this device includes: rubber cover 6 in shaped hollow round table, rubber Cover 6 upper opening diameter identical with the diameter of line bar outer rim, rubber cover 6 upper opening by restraint zone 7 fix online bar and Cross-arm intersection top, rubber cover 6 lower openings edge contacts with cross-arm, the bus of round table-like rubber cover 6 and line rod axis Angle is more than or equal to 40 ° and less than or equal to 50 °, and restraint zone 7 is soft steel bar.

Preferably, the bus of round table-like rubber cover 6 and the angle of line rod axis are 45 °.

This utility model beneficial effect includes: interruption maintenance plan is reduced, the most just reduces frequency of power cut；Improve Power supply reliability, improves good service；Having a power failure and extract bird's nest and need operating personnel to step on bar to complete, frequency of power cut reduces, and subtracts simultaneously Lack operating personnel and stepped on the frequency of bar operation, decrease danger；Charged excision bird's nest frequency reduces, and reduces livewire work personnel's Job content.Owing to this circuit birds nest frequency is the highest, spy is repeatedly arranged to patrol for this circuit, after bird's nest quantity reduces, Spy patrols number of times and can reduce, reduce operations staff work.

Accompanying drawing explanation

Fig. 1 is that shaft tower top view structure of the prior art sets up position view with bird's nest；

Fig. 2 is that the shaft tower front view in this utility model embodiment sets up position view with bird-proof device；

Fig. 3 is the structural representation of the bird-proof device in this utility model embodiment.

Detailed description of the invention

In order to provide reduction birds rate of nesting on shaft tower, it is to avoid birds activity causes the implementation of line fault, This utility model embodiment provides a kind of bird-proof device, below in conjunction with Figure of description to preferred embodiment of the present utility model Illustrate.

Refering to shown in Fig. 2, it is trapezoid area in figure that bird-proof device sets up position.Refering to shown in Fig. 3, this utility model is implemented Example provides a kind of bird-proof device, it is characterised in that described device includes: rubber cover 6 in shaped hollow round table, the top of rubber cover 6 Opening diameter is identical with the diameter of line bar outer rim, and rubber cover 6 upper opening fixes online bar and cross-arm intersection by restraint zone 7 Top, rubber cover 6 lower openings edge contacts with cross-arm, and the bus of round table-like rubber cover 6 and the angle of line rod axis are more than In 40 ° and less than or equal to 50 °, restraint zone 7 is soft steel bar.

Preferably, the bus of round table-like cover is 45 ° with the angle of line rod axis.

By consulting dielectric friction factor, the angle of the bus and line rod axis that calculate round table-like rubber cover 6 is 45 ° Time, the tightst with the joint of line bar, the intersection of birds least easily online bar and cross-arm nests, the biggest or the least in angle Time, birds all can be caused to can continue to nest.

In sum, the scheme that this utility model embodiment provides so that interruption maintenance plan reduces, the most just reduces and stops Electricity number of times；Improve power supply reliability, improve good service；Have a power failure and extract bird's nest and need operating personnel to step on bar to complete, have a power failure time Number reduces, and decreases operating personnel simultaneously and steps on the frequency of bar operation, decreases danger；Charged excision bird's nest frequency reduces, and reduces The job content of livewire work personnel.Owing to this circuit birds nest frequency is the highest, spy is repeatedly arranged to patrol, bird for this circuit Nest quantity reduce after, spy patrols number of times and can reduce, reduce operations staff work.

Obviously, those skilled in the art can carry out various change and modification without deviating from this practicality to this utility model Novel spirit and scope.So, if of the present utility model these amendment and modification belong to this utility model claim and Within the scope of its equivalent technologies, then this utility model is also intended to comprise these change and modification.
