Wind power generation blade cleaning device

The invention belongs to the technical field of wind power generation, and discloses a wind power generation blade cleaning device. Comprising a connecting rod and two arc-shaped rods fixedly connected to the two ends of the connecting rod respectively, and the arc-shaped rods are elastic and tightly attached to the surfaces of the wind power generation blades. By arranging the spraying assembly and the cleaning assembly, when a cleaning agent needs to be sprayed to the wind power generation blade, the water pump is started to convey the external cleaning agent into the connecting pipe, so that the connecting pipe is filled with the cleaning agent, and after filling, the cleaning agent is continuously input into the connecting pipe to increase the pressure of the connecting pipe; the cleaning agent breaks through a sealing piece and enters a water outlet cavity of a round block from a connecting sleeve and a water outlet pipe, water in the water outlet cavity is sprayed to the surface of a wind power generati
