The U-shaped block 57 passes through a sliding hole 60 provided on the extension seat 56, and the sliding U-shaped block 57 is adapted to slide in the sliding hole 60, so that the user can adjust the position of the U-shaped block 57 conveniently. The user can adjust the position of the U-shaped block 57 according to the diameter of the liquid pipe 52 body. The sliding hole 60 is provided to prevent the liquid pipe 52 from getting knotted at the bend, thereby reducing the fluidity of the liquid in the liquid pipe 52. An extension tube 53 is provided on the side of the U-shaped block 57 body, and the extension tube 53 is fixed on the half U-shaped column on one side of the U-shaped block 57.

[0037] The present application also provides a working principle of a photovoltaic panel cleaning drone device: the user first fills the liquid container under the body with cleaning liquid and seals the opening, then manually rotates the extension seat and adjusts the angle of the extension tube. When the angle is adjusted, the user starts the drone, plans a path based on the overall size of the photovoltaic panel and the area of the photovoltaic panel, and transmits the planned path to the wireless signal module and the path planning module via wireless. The path planning module uses Beidou positioning to send its own position and receive instructions in real time through the wireless signal module. When the drone takes off to clean the photovoltaic panel, the user opens the liquid pipe connected to the body through a handheld terminal. The liquid pipe is connected to the liquid container on the body, and the liquid switch is controlled to close by an electric valve. The electric valve is an existing product and will not be described in detail here. The liquid pipe transports the cleaning liquid and sprays it from the nozzle. The nozzle is an existing product and will not be described in detail here. When the user needs to adjust the nozzle angle to more than 90 degrees, he only needs to adjust the liquid pipe left and right to always keep the liquid pipe within the rotating axis and groove to prevent the liquid pipe from getting tangled and affecting the drone's cleaning operation of the photovoltaic panel.
