Problems solved by technology
Due to structural differences and the influence of environmental factors, bird nests are often built on transmission line towers in areas lacking tall trees, posing a threat to safe power supply
[0004] The hazards of bird nests to transmission lines mainly include the following points: (1) increase the probability of short circuit of transmission lines; Prompt insulation damage and increase the probability of short circuit; (3) Dirty insulators reduce their insulation strength, and increase the probability of pollution flashover during the foggy season in spring and autumn
[0005] Due to the high randomness of the appearance of bird's nests, in the prior art, the discovery and removal of bird's nests is generally carried out manually, that is, the power supply maintenance personnel inspect the transmission line with the naked eye, and once a bird's nest is found, it is immediately cleaned manually. However, This method consumes a lot of manpower and material resources, and the efficiency of bird nest removal is not high

Embodiment Construction
[0018] The implementation of the transmission line anti-interference system of the present invention will be described in detail below with reference to the accompanying drawings.
[0019]For some areas lacking trees, when birds in this area are looking for a suitable place to build nests and reproduce the next generation, because the cross-arms of transmission line towers are very suitable for birds to build nests, birds often choose them as nesting places. However, during the nesting process, wooden sticks, iron wires, weeds, plastic bags and other sundries will be brought back. These sundries falling on the line may easily cause the line to "mistakenly" trip. At the same time, the birds will excrete a lot of feces during their life on the pole tower. The pollution flashover caused by line insulators will give inspectors a false impression of insulator flashover, which will have many adverse effects on line operation and maintenance.
[0020] In the prior art, in order to ov...

The present invention relates to a transmission line anti-interference system which comprises an ultrasonic bird repeller, a bird nest identification device, a robot main body structure and an SD memory chip. The ultrasonic bird repeller, the bird nest identification device and the SD memory chip are in the robot main body structure which is used for inspecting a transmission line. The bird nest identification device is used for carrying out nest identification on the iron towers near the transmission line. The ultrasonic bird repeller is connected to the bird nest identification device and is used for controlling the frequency of bird driving ultrasonic waves based on a nest identification result. Through the system, the bird nest at the iron tower near the transmission line can be subjected to accurate species identification and deportation, and the interference of the transmission line by the birds in the bird nest is effectively overcome.
Description
[0001] The present invention is a divisional application of a patent with the application number 2015109625366, the application date is December 17, 2015, and the invention name is "Transmission line anti-interference system". technical field [0002] The invention relates to the field of power grid maintenance, in particular to an anti-interference system for transmission lines. Background technique [0003] At present, except for a few underground cables, most of the power transmission is overhead transmission lines. The voltage level of the overhead transmission line is different, and the tower structure and wiring method are also different. Due to structural differences and the influence of environmental factors, bird nests often occur on transmission line towers in areas lacking tall trees, posing a threat to safe power supply. [0004] The hazards of bird nests to transmission lines mainly include the following points: (1) increase the probability of short circuit of ...
