The invention provides a mosquito killer. One or more mosquito repelling devices and a mosquito killing device are arranged in a mosquito killing space. The mosquito repelling devices can emit messages for repelling mosquitoes, and the mosquito killing device is further provided with a weakening device capable of weakening the effect of the messages emitted by the mosquito repelling devices. Through the weakening device, the mosquito killing device weakens the messages emitted by the mosquito repelling devices around the mosquito killing device, so that the intensity of the messages around the mosquito killing device is lower than that of the messages at other parts in the space, mosquitoes in the space will automatically get close to the mosquito killing device, and then mosquitoes are killed through an escape preventing device. Besides, the mosquito repelling devices can be placed at multiple positions in the space according to practical needs, mosquitoes are expelled to the mosquito killing device through the mosquito repelling devices and are killed, and therefore the killing range can be widened, and the killing effect can be improved.

The invention provides a transformer substation self-operation bird repelling device comprising a moving trolley and rail lines which are drawn in a transformer substation. The moving trolley is provided with a radar detection module, an ultrasonic bird repelling module and a first camera. The bottom part of the moving trolley is corresponding to a rail line setting recognition mechanism. A compartment is arranged behind the moving trolley. An unmanned aerial vehicle is arranged on the compartment. A cleaning mechanism for processing the nest is arranged below the unmanned aerial vehicle. An accommodating mechanism for collecting the nest is arranged on the compartment. The rail lines are set for the moving trolley so that the trolley is enabled to perform tour inspection in the transformer substation along the rail lines to repel birds, and the device is provided with multiple modules for monitoring the birds and modules for repelling the birds and thus the bird detection and repelling effect is better. The moving trolley is provided with the unmanned aerial vehicle for cleaning the high-altitude nest so that the function is more powerful.

The present invention provides a mosquito killer. By setting one or more insect dispelling devices and disinfestation devices in the mosquito dispelling space, the disinfestation device can send out annoying messages to mosquitoes. The device for weakening the message effect of the disinfestation device. The disinfestation device weakens the dissemination of the dissemination of information by the disinsection device around the disinsection device, so that the strength of the message around the disinsection device is weaker than that of other parts in the space, so the space The mosquitoes in the space will automatically move closer to the extermination device, and then be killed by the anti-escape device; and the present invention can place insect repellent devices in multiple places in the space according to actual needs, and expel mosquitoes to the exterminator through the insect repellent devices If it is killed everywhere, it can realize the increase of killing range and killing effect.

The invention provides a bird nest eliminating vehicle for checking power transmission lines. The bird nest eliminating vehicle comprises a vehicle body and a carriage arranged at the rear portion of the vehicle body, the vehicle body is provided with a radar detection module, an ultrasonic wave bird-dispelling module and a first camera lens, the carriage is provided with an unmanned aerial vehicle, a cleaning mechanism for disposing bird nests is arranged below the unmanned aerial vehicle, several accommodation cavities used for collecting the bird nests are arranged at the rear portion of the carriage, a protection plate is rotatably arranged at the portion, corresponding to the accommodation cavities, above the carriage, and solar cell panels are arranged at the four corners of the protection plate through piezoelectric cantilever arms. According to the bird nest eliminating vehicle for checking the power transmission lines, by using the vehicle body to conduct checking along the power transmission lines, the birds are dispelled,; meanwhile, the bird nest eliminating vehicle is provided with multiple modules for monitoring the birds and modules for dispelling the birds, the effects of detecting and dispelling the birds are better, the unmanned aerial vehicle is arranged on the vehicle body, high-altitude bird nests can be eliminated, and the functions are more powerful.

The invention relates to the biochemical field, in particular to a bird repelling agent and a preparation method thereof. The bird repelling agent comprises 4-8 parts of borneol by weight and 40-50 parts of ethanol by weight. The preparation method of the bird repelling agent comprise the step of putting and dissolving 4-8 parts of borneol by weight in 40-50 parts of ethanol by weight to obtain first mixture. Due to the bird repelling agent and the preparation method thereof provided by the invention, the toxicity of the bird repelling agent can be reduced. The bird repelling agent has the advantages of good biological performance, high safety, environmental friendliness, small pollution, high purity, good water solubility, high efficacy and slow release.
