Abstract

The utility model relates to power transmission line equipment, in particular to a bird-preventing position occupier for a transmission line. In order to solve a technical problem that birds are easy to nest in a steel bar junction at an end part of a cross arm of a power transmission iron tower, a bird-preventing position occupier for a transmission line which can be mounted on a power iron tower is provided. The bird-preventing position occupier comprises a U-shaped fixing bracket and is characterized by comprising a bottom plate of the position occupier and three side plates of the position occupier; the bottom plate of the position occupier is connected with the U-shaped bracket together; and the three side plates of the position occupier are fixed on the bottom plate of the position occupier. As the structure is adopted in the utility model, the shape and the size of a triangular body formed by the other parts are the same as a space which is suitable for the birds to nest at the end part of the cross arm of the power transmission iron tower; therefore, the space in which the birds are easy to nest is occupied so that the birds cannot be nested in the space to effectively avoid short-circuit accidents caused by nesting of the birds; and moreover, the bird-preventing position occupier for the transmission line has the advantages of good effect on nesting prevention, simple structure and convenience in mounting and dismounting.

Description

Transmission line is prevented the bird occupying device

Technical field

The utility model relates to a kind of power transmission line equipment, is specially the anti-bird occupying device of a kind of transmission line.

Background technology

Along with the improvement of biological environment in recent years; Birds quantity increases, and a large amount of transmission lines are exposed to the field, endangered by various birds; Have a strong impact on power system security, because the caused electric power system circuit breaker trip of bird pest accident takes place and the frequency increases thereupon.Birds mainly are because the structure of electric power pylon causes to the harm of transmission line: in order to improve the fail safe of iron tower; Cross-arm end at suspension insulator string; The interconnection herein of many stiffening angles is arranged, and the structure of its formation is fit to birds and is nesting at this very much.Owing to usually comprise electric conducting materials such as wire in the material of nesting of birds, cause instantaneous short circuit easily, and, cause insulator string insulating sublayer decreased performance, even cause failure of insulation owing to birds outside defecation from nest.

In order to address the above problem, people have taked the measure of several anti bird: 1, windmill type bird proof device lean on the rotation of windmill to frighten the birds of nesting away, but this method does not have the effect of anti-bird at all under calm situation; 2, ultrasonic wave bird proof device relies on ultrasonic wave to drive birds, but the speed of this method performance effect is slow and birds are easy to generate adaptability; 3, the artificial Bird's Nest that directly destroys, this method need drop into great amount of manpower, and destroys soon, and birds can be nested again again, and effect is bad, also is unfavorable for the protection to birds.

The utility model content

Thereby the utility model is to be prone to nest at many angle steel infalls of electric power transmission iron tower cross-arm end and to cause this technical problem of wire short-circuiting in order to solve birds, and a kind of anti-bird occupying device of transmission line that is installed on the electric power electricity iron tower is provided.

The technical scheme of the utility model is: a kind of transmission line is prevented the bird occupying device, comprises the U-shaped fixed support, it is characterized in that: it comprises the occupying device base plate that links together with the U-shaped support and is fixed on has three blocks of occupying device side plates on the occupying device base plate.

Compared with prior art; The utlity model has following advantage and good effect: because the utility model has adopted said structure; U-shaped support through the bottom is fixed on the electric power tower cross-arm, and the triangle body shape that other parts form is identical with the space that the suitable birds that size and electric power pylon cross-arm end exist are nested, and has just in time occupied the space that birds are nested easily; Birds can't be nested at this, thereby effectively avoided birds to nest and the generation of the short circuit accident that causes; The anti-bird point of this transmission line position device is prevented the effective, simple in structure, easy to loading and unloading of Bird's Nest.

Fig. 2 is the right view of Fig. 1;

Fig. 3 is the scheme of installation of the anti-bird occupying device of transmission line;

Fig. 4 is the anti-result of use sketch map of bird occupying device on electric power pylon of transmission line.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Like Fig. 1, shown in Figure 2, the anti-bird occupying device of the described transmission line of the utility model comprises U-shaped support 1, occupying device base plate 5 and three blocks of occupying

device side plates

4,6,7.Base plate 5 is formed triangle body with

side plate

4,6,7, and its shape just in time with on the electric power pylon is easy to the space fit that birds are nested with size, can design different shapes for different iron towers, to guarantee best performance occupy-place effect.Clamping screw 2 is arranged on the U-shaped support, and its quantity is no less than 2.

During use; Occupying device 8 is put into electric power pylon 9 cross-arm ends be fit to the position that birds are nested, simultaneously U-shaped support 1 is inserted on the electric power pylon cross-arm angle bar, clamping screw 2 is screwed in the screwed hole of U-shaped support 1; Utilize bolt that bird proof device is fixed on the electric power pylon cross-arm, make its firm connection.

Claims

1. the anti-bird occupying device of transmission line comprises the U-shaped fixed support, and it is characterized in that: it comprises the occupying device base plate that links together with the U-shaped support and is fixed on has three blocks of occupying device side plates on the occupying device base plate.
