Bird repellent device for cross arms of suspension high-voltage line tower

Abstract

The invention discloses a bird repellent device for cross arms of a suspension high-voltage line tower. The device comprises a connecting end, a box body fixed below the connecting end, an air inlet component at the bottom of the box body, and a bent end at the top of the box body. Compared with the prior art, the device of the invention has a simple structure, and is suitable for bird repellent protection operations of equipment with relatively high height at the cross arms of transmission line towers. When birds stay at the bent end, the device is deflected as a whole by the own weight of the birds, then a second opening is opened, a driving motor is controlled to open a second ventilation pipe after a controller receives signals from a pressures sensor, furthermore, the airflow velocityof a first cavity is changed, the second opening can be further enlarged under the wind power of the second ventilation pipe, the release of bird repellent from the bent end can be accelerated, and birds on the bent end can be effectively repelled. The device of the invention has reasonable structure design, easy installation, long service life, and good bird repellent effect.

Description

technical field [0001] The invention relates to the technical field of bird repelling devices, in particular to a bird repelling device for a suspended crossarm of a high-voltage line tower. Background technique [0002] In recent years, with the enhancement of people's awareness of environmental protection and the continuous improvement of the ecological environment, the population, number and range of activities of birds living in nature have gradually increased. Because most of my country's power transmission overhead lines run in the wild, it is not easy to be monitored by manpower in time, so they are greatly affected by bird activities. Birds usually build their nests on high-voltage wire racks. When the wind blows, the branches and wires used to make the nests are likely to form a short circuit. It is possible that a power failure due to a small bird's nest will not only bring inconvenience to thousands of households, but also bring losses to the factory. And there ...

AI Technical Summary

Problems solved by technology

The frequent occurrence of bird damage accidents not only makes the operation and maintenance units suffer great losses in manpower and material resources, but also seriously threatens the safe operation of the power grid.

[0003] Currently used bird repellents mainly include windmill type, sound, ultrasonic, bird repellent and other bird repellents, wherein the structure of the bird repellent bird repellent is relatively single, the scope of action is small, and there is still a lack of effective bird repellent release mechanism to Realize the discharge of bird repellant, so there is an urgent need for a structurally reasonable bird repellent release mechanism to assist bird repellent operations
