Support frames 221 are placed between the top recesses of the water storage tank 201. A filter screen plate 203 is installed on the top of the water storage tank 201. The support frames 221 are used to support the filter screen plate 203. The other end of the rotating rod 206 is movably penetrated through the inner wall of the treatment box 204. The dust filter 222 is used to filter the air entering the air inlet hole 210. The air inlet hole 210 and the water outlet hole 211 are located on both sides of the partition plate 205. A guide pipe 213 is fixed to the bottom of the treatment box 204, which is used to guide the water output by the water outlet hole 211. The outer wall of the guide pipe 213 is fixedly provided with a fixing part 214. The fan blade 208 is located in the circular hole of the treatment box 204.

When the air blows through the strip-shaped filter screen 103, the back-blowing air can blow away the dust attached to the surface of the strip-shaped filter screen 103, so as to clean the dust on the surface of the strip-shaped filter screen 103. When the water in the water storage tank 201 is drained, the previously started one of the second electric valves 218 and the first electric valve 216 can be closed.

[0047] When it rains outside, the falling rain will fall on the filter screen plate 203, then pass through the mesh of the filter screen plate 203 and enter the inside of the water storage tank 201, and be stored. When the strip-shaped filter screen 103 needs to be cleaned after a long time of use, the monitoring personnel in the monitoring room can use the monitoring equipment and the antenna 119 to send a command to the controller 115 to start one of the second electric valves 218 (the second electric valve 218 connected with the connecting pipe 219) and the first electric valve 216. At this time, the controller 115 receiving the specified command will start the first electric valve 216 and one of the second electric valves 218. When one of the second electric valves 218 is started, the water in the water storage tank 201 will directly pass through the communication pipe 220 and the first electric valve 216 with the open valve, enter the inside of the water outlet pipe 215, and then be transported to the water wheel 207. When the water wheel 207 is continuously impacted by the water output by the water outlet pipe 215, the rotating rod 206 will quickly rotate under the cooperation of the processing box 204, the partition plate 205, and the rectangular plate 212. At the same time, the water flowing down from the water wheel 207 will also pass through the water outlet hole 211 and enter the inside of the flow guide pipe 213. The continuously rotating rotating rod 206 will also continuously drive the fan blade 208 to rotate. When the fan blade 208 continuously rotates, the air in the environment will be filtered and then sucked into the inside of the air guide shell 209 under the cooperation of the processing box 204, the air inlet hole 210, the partition plate 205, the dust filter 222, and the rectangular plate 212. Then the air is transported to the inside of the connecting pipe 219, and then transported to the inside of the connector 217 through the cooperation of one of the second electric valves 218 with the open valve. Then the air is divided into two directions of the strip-shaped filter screen 103. When the air blows through the strip-shaped filter screen 103, the back-blowing air can blow away the dust attached to the surface of the strip-shaped filter screen 103, thereby cleaning the dust on the surface of the strip-shaped filter screen 103. When the water in the water storage tank 201 is drained, the previously started one of the second electric valves 218 and the first electric valve 216 can be closed.

[0048] Among them, the fan 106, the controller 115, the infrared temperature sensor 118, the antenna 119, the first electric valve 216, and the second electric valve 218 are all prior art, and their models can be selected according to actual conditions, and will not be explained here.
