Bird repelling device capable of adjusting light according to wind directions

Abstract

A bird repelling device capable of adjusting light according to the wind direction comprises a supporting frame, a concave reflector is fixedly embedded in a wind bowl, a limiting ring is movably connected to the top of a supporting plate and on a sleeve, a vertical reflector is rotationally connected to the top of the wind bowl, and plane reflectors which are evenly distributed are movably hingedto the top of a base. A downward reflection light area is formed through the concave reflectors, birds are prevented from nesting on the lower contact net, an upward reflection light area is formed through the vertical reflectors and the plane reflectors to repel the birds passing through the upper space, the three vertical reflectors face the same direction through the limiting ring, and when the birds pass through the area along the wind, the reflected light directly irradiates the eyes of the birds, so that the birds are difficult to bear and quickly leave the area, the birds do not stop on the contact net below, and the possibility of bird nesting is avoided from the source.

Description

technical field [0001] The invention relates to the technical field of railway safety, in particular to a bird repelling device that adjusts light according to the wind direction. Background technique [0002] There are often birds nesting on the catenary of the railway. The long branches and bird excrement and other sundries when building the nest are in contact with the wires, which may easily cause a short circuit of the wires. Therefore, bird repellents are installed on the catenary. Commonly used The bird repellent is a wind-powered bird-repelling device installed in areas where birds are easy to nest. The traditional wind-powered bird-repelling device includes three reflective mirrors on the horizontal plane to reflect sunlight to the position where birds are easy to nest. The sunlight is vertical After being illuminated, the reflected light is concentrated in the lower horizontal direction, forming a small reflected light area, but there is a blind spot in the reflect...

[0002] There are often birds nesting on the catenary of the railway. The long branches and bird excrement and other sundries when building the nest are in contact with the wires, which may easily cause a short circuit of the wires. Therefore, bird repellents are installed on the catenary. Commonly used The bird repellent is a wind-powered bird-repelling device installed in areas where birds are easy to nest. The traditional wind-powered bird-repelling device includes three reflective mirrors on the horizontal plane to reflect sunlight to the position where birds are easy to nest. The sunlight is vertical After being illuminated, the reflected light is concentrated in the lower horizontal direction, forming a small reflected light area, but there is a blind spot in the reflected light range, which basically has no function of dispersing the flying birds directly above, and due to the small reflection angle, some birds Humans can gradually adapt to this light after staying in the air for a period of time, resulting in a gradual decrease in the bird repelling effect. After long-term evolution, birds have become more accustomed to flying with the wind. hover over the nest position with the wind, and then gradually adapt to the light of the optical bird repellent. At present, there is no device for repelling birds based on this characteristic of birds.
