An external ultrasonic bird repeller with adjustable emission angle

Abstract

The invention provides an external ultrasonic bird dispeller adjustable in emission angle. The external ultrasonic bird dispeller adjustable in emission angle comprises a bird dispeller support fixed on an overhead line device by use of a fixing device; the bird dispeller support is designed to be hollow; external bird dispelling devices are arranged on the two sides of the top of the bird dispeller support; the ultrasonic emission angles of the working faces of the external bird dispelling devices are adjustable. The external ultrasonic bird dispeller is adjustable in emission angle and the field intensity near the vertical direction of an ultrasonic reflecting surface can be transmitted further, and therefore, compared with the prior art, the external ultrasonic bird dispeller is improved in multiples in bird dispelling range, bird dispelling distance and bird dispelling effect; besides, due to the external design of the ultrasonic bird dispeller, the bird dispeller is mounted by use of a connecting hinge and a connecting rib plate, and therefore, the requirements on the mounting conditions are greatly reduced, a position more convenient for mounting can be selected and the mounting is safer, and non-power-off mounting operation can be realized. The external ultrasonic bird dispeller adjustable in emission angle is suitable for dispelling birds to approach various overhead line devices.

Description

technical field [0001] The invention relates to an ultrasonic generating device, in particular to an ultrasonic bird repelling device for driving birds away from overhead line equipment, the structure of which is external, and the emission angle is adjustable. Background technique [0002] At present, the overhead line equipment of various power companies is mainly composed of 110KV lines, 35KV lines and 10KV lines. The stability of the operation of these overhead lines directly affects the power consumption of regional enterprises, units and residents. [0003] With the advancement of science and technology, the firmness and reliability of the overhead line equipment under the existing technology is increasing day by day. Unless there is a strong natural disaster weather, the usual daily maintenance can ensure the long-term stable operation of the overhead line equipment. However , the existing overhead line equipment still has uncontrollable loss factors, and the biggest ...

AI Technical Summary

Problems solved by technology

It can be seen from the data that the bird repelling ability on the oblique upper side of the bird repellent is extremely weak, and there is a problem that the ultrasonic energy generated by the bird repellent cannot be completely transmitted to repel birds, and the installation requirements of the bird repellent are very high , should be considered from the structure of the bird repellent, the conditions of the installation site, and the scope of the bird repellent. When these three conditions cannot be fully satisfied, the bird repellent effect will be poor or even malfunction. In order to solve The problem of unsatisfactory bird repelling effect caused by various defects in human repellent, wind bird repellent and ultrasonic bird repellent in the prior art, the present invention provides an improved external ultrasonic repellent with adjustable emission angle. Bird device, change the built-in ultrasonic transmitter to an external one, and change the fixed emission angle to an adjustable angle to adapt to various installation conditions, so as to realize all-round 360° bird repelling, which is neither affected by Due to the limitation of installation conditions, the ultrasonic energy for repelling birds can be maximized.
