Brushing device
The invention provides a brushing device which is used for solving the technical problem that the brushing device in the prior art is not convenient for efficiently brushing the inner and outer walls of pipelines. The brushing device comprises a flexible brush body and a brushing surface type regulating mechanism, wherein the flexible brush body comprises a flexible leaf spring and a cleaning block tightly arranged on the flexible leaf spring; a paint delivery pipe is arranged in the cleaning block in a wrapping form; a plurality of pores of which the pore diameters are matched with the paint granularity are distributed on the pipe wall of the paint delivery pipe and are communicated with the paint delivery pipe; the brushing surface type regulating mechanism is tightly connected with the flexible brush body; at least one surface on the cleaning block serves as a cleaning surface; and the brushing surface type regulating mechanism applies at least one of end extrusion force, middle thrust and middle tension to the flexible leaf spring so as to change the surface type of the cleaning surface. The brushing device provided by the invention is more suitable for brushing outer and inner walls of pipelines with irregular cross sections.
