[0022] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0024] For details, please refer to Figure 1 , the tools for removing bird nests on power towers include: A telescopic rod body 3 is a hollow structure, and one end of the telescopic rod body 3 is connected to a base, and the other end of the telescopic rod body 3 is connected to a rotating nozzle 4, and the rotating nozzle 4 is connected to the telescopic rod body 3 through a rotating shaft; the base is connected to the bottom of the drone 1, and the drone 1 is equipped with a solution tank, and a flow pump is provided in the solution tank, and the flow pump is connected to the rotating nozzle 4 through a hose; the hose is arranged in the telescopic rod body 3; the solution tank is filled with insulating liquid.

[0025] The rotating spray head 4 includes two nozzles, a rotating shaft and an orientation ring, the two nozzles are connected to the rotating shaft, the rotating shaft is connected to the hose, and the fixed part of the rotating shaft is fixedly installed on the end of the telescopic rod 3 by screw thread; the rotating part of the rotating shaft is installed with an orientation ring. In this way, the rotating spray head 4 can rotate in a directional manner.

[0026] The telescopic rod body and the rotating nozzle both adopt an insulating structure.

[0027] When used, the drone 1 is controlled to hover over the bird's nest, and the telescopic rod is controlled to extend downward until the rotating nozzle 4 reaches the bird's nest. The flow pump is started, and the insulating liquid impacts the rotating nozzle 4 to rotate and spray the bird's nest. The insulating liquid plays a lubricating role, and the bird's nest is dispersed under the impact of the insulating liquid.

[0028] In order to prevent the bird's nest from being too tight, the impact force of the insulating liquid alone cannot disperse the bird's nest. In one embodiment of the present invention, a cutter 5 is fixedly connected to both nozzles. Specifically, the outer shell of the nozzle is provided with a fixing groove, and the handle of the cutter 5 is fixed to the fixing groove of the nozzle through a fixing hoop. In this way, the cutter 5 rotates under the drive of the nozzle to cut and disperse the resin weeds, thereby quickly disintegrating the bird's nest structure.

[0029] In addition, there are debris such as thin iron wires in some bird nests, so a cutting knife 5 with a barb is designed, such as Figure 2 The cutter 5 is designed as a curved knife, with the barb facing the blade side, so that the barb can catch the thin wire to prevent it from falling on the wire and causing a short circuit.

[0030] In another embodiment of the present invention, the telescopic rod body 3 is an electric telescopic rod. The driving device of the electric telescopic rod is electrically connected to the controller 2, and the controller 2 is electrically connected to the flow pump. A laser ranging sensor is installed at one end of the telescopic rod body 3 where the rotating nozzle 4 is installed, and the laser of the laser ranging sensor points to the extension direction of the telescopic rod. The drone 1 has a camera at the bottom.

[0031] A camera is set up to capture the bird's nest, and a laser sensor is set up to control the extension amount of the electric telescopic rod to avoid over-extension. The operation is automated through the controller 2.

[0032] Specifically, the present invention provides a method for removing a bird's nest on a power tower, comprising the following steps: S1. Collect pictures of power poles and towers through a camera and identify the pictures.

[0033] The camera uses a large depth of field lens, which can capture the distance from the camera to the target.

[0034] The controller of the drone sends the collected pictures to the remote terminal through the 5G communication chip, and the remote terminal uses the target recognition algorithm to identify the bird's nest target from the picture. If the bird's nest target is identified, the controller of the drone calculates the movement route of the drone based on the coordinates of the bird's nest target in the picture and the pre-set expected coordinates. The authorization information and movement route are sent to the controller of the drone.

[0035] If the bird's nest target is not identified, the received image is cleared.

[0036] S2. If a bird's nest is identified in the picture, the drone is controlled to hover above the bird's nest, and the telescopic rod is controlled to extend downward until the distance signal collected by the laser ranging sensor reaches a set distance threshold.

[0037] After receiving the movement route, the controller controls the drone to adjust its position according to the movement route, and controls the drone to hover when it reaches the end of the movement route, and collects pictures at this point. The new picture is uploaded to the remote terminal, and the remote terminal determines whether the coordinates of the bird's nest in the picture are the expected coordinates. If they are expected, authorization information is generated. If they are not expected coordinates, a new movement route is generated and sent to the drone controller.

[0038] If the controller receives the authorization information, it controls the electric telescopic rod to extend downward, and continuously receives the distance signal collected by the laser ranging sensor, processes the distance signal to obtain the distance between the electric telescopic rod and the target below. If the distance reaches the set distance threshold, the electric telescopic rod is controlled to stop extending, and the flow pump is controlled to start.

[0039] S3, control the flow pump to start and start timing, when the timing time reaches the set time threshold, control the flow pump to pause, and re-collect the picture to verify whether there is a bird's nest in the picture.

[0040] The flow pump is started and the timing starts. If the timing reaches 10S, the flow pump is controlled to pause. The image is collected again and uploaded to the remote terminal. The remote terminal uses the target detection algorithm to identify the bird's nest target in the image. If the recognition is successful, the remote terminal sends the authorization information to the drone controller. If the recognition is unsuccessful, the remote terminal sends a termination command to the drone controller.

[0041] If the drone controller receives the authorization information, it controls the flow pump to run for another 10 seconds; if the drone controller receives the termination command, it controls the electric telescopic rod to retract to the shortest.

[0042] Although the present invention has been described in detail with reference to the accompanying drawings and in combination with the preferred embodiments, the present invention is not limited thereto. Without departing from the spirit and essence of the present invention, a person of ordinary skill in the art may make various equivalent modifications or substitutions to the embodiments of the present invention, and these modifications or substitutions shall be within the scope of the present invention. Any person of ordinary skill in the art may easily think of changes or substitutions within the technical scope disclosed by the present invention, and these shall be within the scope of protection of the present invention.
