Insulator sweeper

The invention discloses an insulator sweeper, which comprises an operating rod and a water injection air gun positioned on the operating rod. The rear of a shell of the water injection air gun is provided with a high pressure fan; a power switch is arranged on the high pressure fan; the front end of the high pressure fan is provided with an airflow cavity; the front end of the airflow cavity is provided with a nozzle; the front end of the nozzle is provided with a water-air mixing cavity; an injection pipe is arranged at the front end of the water-air mixing cavity; the nozzle is connected with a water inlet pipe provided with a water outlet switch; and the water inlet pipe has water pressure. The insulator sweeper has a simple structure, the water injection air gun is only required to be arranged on the insulating operating rod, and the water injection air gun is improved slightly on the basis of the prior art and can be used. In addition, the airflow cavity at the front end of the high pressure fan is a tap
