[0014] In the figure: 1 drainage riser, 2 horizontal pipe, 21 water nozzle, 3 roller brush, 4 frame, 41 sliding frame, 42 rotating shaft, 43 connecting rod, 44 fixed rod, 45 second rotating shaft, 5 tension spring, 6 water hose, 7 coil spring. DETAILED DESCRIPTION

[0015] The present invention is further described below:

[0016] See also Figure 1-2 ,

[0017] The present invention discloses a roller brush for cleaning walls, comprising a drainage riser 1, a horizontal pipe 2, a cylindrical roller brush 3, a frame 4, a tension spring 5, a water hose 6 and a coil spring 7. Two parallel horizontal pipes 2 are respectively connected to the side walls of the drainage riser 1; the frame 4 includes a sliding frame 41 that slides with the horizontal pipe 2, and the inner wall of the sliding frame is provided with a rotating shaft 42 for inserting the two ends of the roller brush 3, and a connecting rod 43 is provided between the side walls of the sliding frame 41 at both ends; one end of the two tension springs 5 ​​is connected to the upper and lower side walls of the connecting rod 43, respectively, and the other end is connected to the upper and lower side walls of the connecting rod 43. The outer end of the coil spring 7 is connected to the side wall of the drainage riser 1; the coil spring 7 is a metal strip curled into a spiral structure, its outer end connected to the side wall of the drainage riser 1, and its inner end is a circular ring structure; one side surface of the water hose 6 is fixedly connected to the coil spring 7, its closed end connected to the inner end surface of the coil spring 7, and its open end connected to the outer end surface of the coil spring 7; two fixing rods 44 are provided above and below the side wall of the connecting rod 43, and the inner wall of each fixing rod 44 is provided with a second rotating shaft 45 that is mounted on the inner end of the coil spring 7. The water hose is a tubular belt fabric that can withstand a certain liquid pressure. It can deliver water or foam fire extinguishing liquid at a relatively high pressure, greatly improving the cleaning efficiency of the wall and significantly reducing the workload of the user.

[0018] The fixing rod 44 is arranged parallel to the transverse tube 2 to ensure that the roller brush 3 moves along the direction thereof.

[0019] The surface of the horizontal pipe 2 is provided with a plurality of water spraying ports 21 at intervals. Water flows through the drainage vertical pipe 1, and the horizontal pipe 2 is connected thereto. The water can be sprayed out through the water spraying ports 21, so that the roller brush 3 can automatically get wet during the wall brushing process, and the wall surface can also be flushed with water, thereby improving its cleaning efficiency.

[0020] The surface of the roller brush 3 is in close contact with the wall being cleaned; a gap is provided between the frame 4 and the wall being cleaned to ensure that the frame 4 does not rub or collide with the wall to avoid damaging the wall.

[0021] Working process: When cleaning the exterior wall of a building, first install the roller brush 3 dipped in cleaning liquid on the rotating shaft 42 of the frame 4, then put the sliding frame 41 on it from the front end of the horizontal tube 2, then put the inner end of the coil spring 7 on the outside of the second rotating shaft 45, and finally connect the two ends of the tension spring 5 to the drainage riser 1 and the connecting rod 43 respectively; connect the open end of the water hose 6 to the external water injection device to provide or reduce the water pressure when injecting water into the water hose 6. When the water hose 6 is injected with water, the water hose 6 straightens and expands. , pushing the roller brush 3 forward against the elastic force of the tension spring 5 and the coil spring 7 to realize the left and right movement of the roller brush 3 on the track, thereby making the roller brush 3 brush the wall to perform scrubbing work. When the water hose 6 is released, that is, its internal pressure is reduced, the water hose 6 is moved toward the direction of the drainage riser 1 by the reset action of the tension spring 5. At the same time, due to the reset action of the coil spring 7, it automatically coils around the inner end of the coil spring 7 as the axis. When the scrubbing work is completed, the tension spring 5 is removed and the roller brush 3 can be directly taken out from the front end of the horizontal pipe 2.

[0022] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's description and drawings, or any direct or indirect application in related technical fields, are also included in the patent protection scope of the present invention.
