A bird repelling device that adjusts the light according to the wind direction

Abstract

A bird repelling device that adjusts light according to the wind direction, including a support frame, the inside of the wind bowl is fixedly inlaid with a concave reflector, the top of the support plate is movably connected with a limit ring located on the sleeve, and the wind bowl The top is rotatably connected with a vertical reflector, and the top of the base is articulated with uniformly distributed plane reflectors. The downward reflected light area is formed by the concave reflector to prevent birds from nesting on the catenary below, and the upward reflected light area is formed by the vertical reflector and the plane reflector to expel the birds passing by in the sky. The ring keeps the orientation of the three vertical reflectors in the same direction. When a bird passes by in the downwind, the reflected light will directly hit the bird's eyes, making it unbearable for the bird to leave the area quickly, so it will not stop at the The contact net below avoids the possibility of birds nesting 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.
