Description

Dynamic laser bird-repelling device

The present invention relates to a bird-repelling device, especially a bird-repelling device that uses a light diffraction principle to project a laser light source into a dot pattern, and uses dynamic rotation to make the dots constitute a large area of dynamic interference.

According to a long time, the losses caused by bird damage to agriculture have continued to plague agricultural workers, and the commonly used bird repellent methods are nothing more than artificial bird repellence, scarecrow establishment, and bird net establishment. However, artificial bird repelling takes time and wastes manpower. Scarecrows can be easily spotted by flocks of birds, and the deterrent effect is not good. Setting up a bird net can easily cause birds to get stuck on the net, resulting in bird injury or death, and disrupting the natural ecological balance. Therefore, following the development of laser bird repellent devices, the bird's eyes were temporarily blinded by means of laser light source irradiation, and the purpose of repelling birds was achieved without causing bird injuries.

For the prior technology related to laser bird repelling, please refer to the Republic of China Patent No. 201320893, which discloses a "driving device", which is provided with a fixed plate, a turntable with a control circuit, and a first motor on a fixed seat. , Laser device, second motor, power supply device and remote control device, so as to start the power supply device and control the laser device to rotate at different angles and directions through the remote control device, and then use the laser light to drive birds .
