Abstract
The utility model discloses a bird prevention spacer applied to a transmission line. The bird prevention spacer comprises a spacer panel and a fixation bracket. A number of different sizes of nail holes are arranged on the spacer panel, and a groove is arranged on the lower end face. A bottom plate is correspondingly arranged below the spacer panel. The spacer panel and the bottom plate are mutually hinged through a hinge. The fixation bracket is fixedly arranged below the bottom plate. According to the utility model, the bird prevention spacer is fixed on a power steel tower cross arm through the fixation bracket on the bottom plate; a spine space formed by the spacer panel just occupies a space in which birds easily nest, so that the birds cannot nest in the space; and a short circuit accident caused by bird nesting can be effectively avoided.
Description
Technical field
The utility model relates to a kind of power transmission line equipment protection device, relates to a kind of anti-bird occupying device for transmission line specifically.
Background technology
For a long time, nearly half the fault trip of ultra-high-tension power transmission line is that the birds activity causes.The work of each tripping operation tracing for troubles point causes the loss of tens thousand of units for operation department, and it is bad and the system that influences normally moves to also have considerable part coincidence to occur, and individual cases also cause other accident.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, in the cross-arm end that hangs 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 owing to birds outside defecation from nest, cause insulator string insulating sublayer performance to descend, even cause failure of insulation.In order to address the above problem, people have taked multiple anti-bird measure: first kind of windmill type bird proof device lean on the rotation of windmill to frighten the birds of nesting away, but this method do not have the effect of anti-bird at all under calm situation; Second kind is the 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; The third is the artificial Bird's Nest that directly destroys, and 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.As can be seen, all do not have bird is protected birds simultaneously again to the harm of transmission line the effect that solves in the existing measure.
The utility model content
At above-mentioned the deficiencies in the prior art, the purpose of this utility model provides a kind of anti-bird occupying device for transmission line, thereby easily nests at many angle steel infalls of electric power transmission iron tower cross-arm end and cause this technical problem of wire short-circuiting to solve birds.
To achieve these goals, the technical solution adopted in the utility model is: a kind of anti-bird occupying device for transmission line, comprise occupying device panel and fixed support, offer the drift bolt hole that several vary in size on the described occupying device panel, its lower surface offers groove, correspondence is provided with a base plate below the occupying device panel, is hinged by hinge between occupying device panel and the base plate, is installed with fixed support below base plate.
Preferably, also be provided with hasp between described occupying device panel and the base plate, hasp and hinge are in the different edge of occupying device panel along last.
Preferably, described fixed support is the U-shaped support, at fixed support fastening bolt is installed.
Adopt the utility model of the technical program, its advantage and beneficial effect are: anti-bird occupying device of the present utility model is fixed on the electric power tower cross-arm by the fixed support on the base plate, the spine space that its occupying device panel forms 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; Anti-bird occupying device of the present utility model is prevented the effective, simple in structure, easy to loading and unloading of Bird's Nest.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1 to Fig. 3, anti-bird occupying device for transmission line of the present utility model, comprise occupying device panel 1 and fixed support 4, offer the drift bolt hole 11 that several vary in size on the described occupying device panel 1, its lower surface offers groove, correspondence is provided with a base plate 2 below occupying device panel 1, is hinged by hinge 3 between occupying device panel 1 and the base plate 2, is installed with fixed support 4 below base plate 2.Also be provided with hasp 31 between described occupying device panel 1 and the base plate 2, hasp 31 is in the different edge of occupying device panel 1 along last with hinge 3.Described fixed support 4 is the U-shaped support, at fixed support 4 fastening bolt 41 is installed.
During use, earlier occupying device panel 1 being opened according to circumstances needs, in the drift bolt hole 11 of occupying device panel 1, insert nail 5, occupying device panel 1 and base plate 2 are closed up with hasp 31 fastenings, the back is fixed on this anti-bird occupying device on the electric power tower cross-arm by fixed support 4 and fastening bolt 41 and gets final product again.This anti-bird occupying device namely drives bird does not influence the insulator string that cleans on the maintenance electric power tower cross-arm again, and installing/dismounting is very convenient.
Above-mentioned only is a kind of embodiment of the present utility model; not in order to limit the utility model; those skilled in the art can make various changes and modifications to said structure; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
Claims (3)
1. anti-bird occupying device that is used for transmission line, comprise occupying device panel and fixed support, it is characterized in that: offer the drift bolt hole that several vary in size on the described occupying device panel, its lower surface offers groove, correspondence is provided with a base plate below the occupying device panel, be hinged by hinge between occupying device panel and the base plate, below base plate, be installed with fixed support.
