Abstract

The invention discloses a bird leading frame for a power transmission line. The cone-cylinder-shaped bird leading frame is installed in a tower body of a power transmission tower. The bird leading frame comprises a cylindrical base and a circular mouth ring, the diameter of the mouth ring is more than 10 times that of the base, and a plurality of supporting rods are arranged between the mouth ring and the base. The bird leading frame is installed in the tower body below power transmission tower wires, birds are led to nest in the bird leading frame, the bird leading frame changes a 'blocking' mode in the traditional bird repellent method, and an 'evacuation' method is adopted, so that influences of the birds on operation of the power transmission line are reduced, and living and multiplying of the birds are also protected.

Description

A kind of used for transmission line draws the bird frame

Technical field

The present invention relates to used for transmission line and draw the bird device.

Background technology

In prior art, normal employing is various prevents the bird measure of driving that birds perch on cross arm of tower or prevents that birds droppings from forming the quarantine measures of discharge channel.

1. install large disk track insulator or umbrella cover additional in the suspension insulator upper end.

2. use glass fibre to make the shutoff case and carry out shutoff, can stop birds and do nest on cross arm of tower.

3. it is the bird measure of driving that many power supply units are commonly used that bird-resistant is installed.

4. the induced electricity pole plate utilizes the high voltage electric energy of circuit self transmission that 1 metal polar plate insulated with cross-arm is installed above insulator.

But there is following defect in prior art:

1. large disk track insulator or umbrella cover: to the circuit successful of 110kV and following electric pressure, along with the rising of electric pressure, the required distance of flashover is increasing, and effect is also poorer.

2. shutoff case: install cumbersomely, be unfavorable for carrying out follow-up service work.

3. bird-resistant: after long-play, the bird thorn can corrosion and aging, the reduction effect on driving birds.

4. induced electricity pole plate: cost of manufacture is high, operating experience is few.

Summary of the invention

Technical problem to be solved by this invention just is to provide a kind of used for transmission line and draws the bird frame, simple in structure, with low cost, and effect on driving birds is good.

For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of used for transmission line draws the bird frame, what cone barrel was installed in the tower body of transmission tower draws the bird frame, describedly draw the choma that the bird frame comprises columniform base and annular, described choma diameter is more than 10 times of base diameter, is provided with some support bars between described choma and base.

Preferably, described support bar is waste wire, and it is circular that described choma is that iron wire is bent into, between described support bar and choma by the iron wire colligation.

Preferably, described base is the bending of waste wire termination and closes up the cylinder of formation.

Preferably, described support bar is the circular arc linear structure to drawing bird frame outer circumferential sides protuberance.

Preferably, this voltage that draws bird frame place transmission line of electricity is greater than 110kV.

Preferably, described slide plate left end is fixed an arch bearing, in the arch bearing, bearing is installed, and described armature spindle is through described bearing.

Install and draw the bird frame in the tower body of the present invention below the transmission tower wire, the guiding birds are cooked nest within drawing the bird frame.As the support bar waste wire that draws the main skeleton structure of bird frame, be to make material, it is firm that one end of wire is distinguished colligation by iron wire, the other end is broken aluminium wire, and bending aluminium wire termination makes each aluminium wire connect into a columniform integral body, wholely like this draw bird and put up the cone barrel seedpod of the lotus shape of hollow (or cry).Thereby after the employing technique scheme, advantage of the present invention is:

1. this draws the bird frame and utilizes waste wire to make, and draws materials easily, with low cost.

This to draw bird frame manufacture craft simple, easy for installation, be convenient to promote on a large scale.

3. this draws the bird frame and changes tradition and drive the mode that bird " block up ", adopts the method for " dredging ", has reduced the impact that birds move transmission line of electricity, also makes multiplying and living of birds be protected.

The accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the invention will be further described:

Fig. 1 is for drawing bird frame front view;

Fig. 2 is for drawing bird frame vertical view.

Embodiment

Fig. 1 and Fig. 2 show the concrete structure that used for transmission line of the present invention draws the bird frame, and what cone barrel was installed in the tower body below the transmission tower wire draws the bird frame.

Describedly draw the choma 3 that the bird frame comprises columniform base 1 and annular, described choma diameter is more than 10 times of base diameter, is provided with some support bars 2 between described choma and base.The choma diameter is 45mm, and base diameter is 20mm, is highly 50mm, and base top is 35mm to the height of choma, and described support bar is that waste wire is made, and it is circular that described choma is that iron wire is bent into, between described support bar and choma by the iron wire colligation.Described base is the bending of waste wire termination and closes up the cylinder of formation.Described support bar is the circular arc linear structure to drawing bird frame outer circumferential sides protuberance.This voltage that draws bird frame place transmission line of electricity is greater than 110kV.
