A bird's nest removal device for high-voltage electric towers

Abstract

The invention discloses a bird nest eliminating device used on a high-voltage tower. The bird nest eliminating device comprises a vertical rod and a grabbing mechanism. The grabbing mechanism comprises a box body, a fixed clamping handle, a movable clamping handle, a telescopic spring and a control mechanism. The movable clamping handle and the fixed clamping handle are respectively arranged at the left end and the right end of the box body. The inside of the fixed clamping handle and the inside of the movable clamping handle are respectively provided with a plurality of cleaning needles. The box body comprises a top board, a left side board, a right side board and a bottom board. The bottom of the bottom board is connected with the upper end of the vertical rod. The fixed clamping handle is connected with the top board. The lower end of the movable clamping handle penetrates through a box body chute and extends into the box body. The telescopic spring is mounted in the box body. The control mechanism comprises a traction rope, a reel, a rocking handle, a hook, a guiding wheel and a pulley. The bird nest eliminating device has advantages of simple structure and convenient operation. Not only can integral stable grabbing and movement of the bird nest for preventing scattering or inclination of the bird nest in the grabbing process be realized, but also the bird nest eliminating device is suitable for integral movement of the bird nests with different sizes. The bird nest eliminating device performs functions of effectively eliminating the bird nests on the high-voltage tower and ensuring normal operation of a power grid.

[0002] In recent years, due to the improvement of the environment and effective protection of wild animals, birds have reproduced rapidly, and the number of birds in cities has increased significantly. Although various types of bird repellents are used on transmission lines and high-voltage towers and anti-bird nesting devices, but it is still impossible to completely prevent birds from building nests on power supply equipment such as high-voltage electric towers, pole cross arms, and isolating switches. Bird nests are generally composed of branches and soil, and some birds may put some metal Once the bird's nest is built on the high-voltage tower or pole, the metal, soil and bird droppings in the bird's nest will have a certain impact on the insulation performance of the power facility, especially in the In bad weather such as windy and rainy, accidents may occur after hard objects such as metal wires that make up the bird's nest come into contact with the wires, resulting in accidents such as short circuits and power outages, which seriously threaten the safe operation of power grid equipment

[0003] Therefore, when line patrol workers find bird nests on high-voltage electricity towers or poles, they need to remove the bird nests as soon as possible. In the existing staff, they climb the poles or towers to directly remove the bird nests. This method not only The climbing process is dangerous, and the staff may get an electric shock. Therefore, removing the bird’s nest manually will usually result in a power outage, which will affect the power supply. There are also hooks or insulating rods that are used to directly disperse or poke the bird’s nest. Scattered, without the need for staff to climb, this method will cause some damage to the birds and affect the reproduction of the birds; there are also two movable claws for grasping, the two movable claws are on the same grasping seat, and the two movable claws are on the same grasping seat. Under the action of the control part, it can be closed or separated to clamp the bird's nest. In this way, the two movable claws have the same fulcrum gripping seat, and the distance between the fulcrum positions is limited, which cannot adapt to different sizes of bird's nests. For larger bird's nests, it is still There is some damage, and the two movable claws can only clamp the sides of the bird's nest. If the clamp is not the middle of the bird's nest, the bird's nest is prone to tilting, scattering, and falling; if multiple movable claws are installed, it will As a result, the entire clearing device is complex, costly, and inconvenient to operate; as for the control unit directly operating the handle of the grip handle, although the operation is convenient, the range of movement of the connecting buckle is limited, and the pulling distance of the pull cord is limited, which means that the two movable claws are open. The opening is limited, it is inconvenient to pick up the slightly larger bird's nest, and there is a danger of easily destroying the bird's nest, which is not conducive to the reproduction of birds
