[0031] Embodiment 2:

[0032] The cleaning component 2 includes a slide plate 201, which is slidably arranged on the inner wall of the back side of the water intake bin 7, and two fixing components 3 are arranged on the top of the slide plate 201. Two dovetail grooves 202 are arranged on the surface of the slide plate 201, and dovetail bars 203 are slidably connected to the inner walls of the two dovetail grooves 202.

A connecting pipe 210 is fixedly provided on the surface of the diversion tank 209. One end of the connecting pipe 210 is fixedly connected to a water injection pipe 211 through a connecting flange. One end of the water injection pipe 211 is fixedly provided with a telescopic hose 212. The two partitions 207 divide the interior of the rectangular water spray frame 205 into two independent parts. The diversion tank 209 and the two water pipes 208 are used to realize water injection at two places. Compared with the existing one-place water injection method, the two diverted wastewaters generated by the one-place water injection method are prevented from converging at the part of the rectangular water spray frame 205 away from the water injection port (the movement directions of the two wastewaters are opposite, resulting in violent collision, reducing the flushing effect of the nearby nozzle 206), and the flushing effect of the nozzle 206 away from the water injection port is guaranteed. The diversion tank 209 and the two water pipes 208 can divide the wastewater into two streams, and the two streams of wastewater flow into the two parts separated by the two partitions 207 respectively, and then are sprayed out from the nozzle 206 to clean the inner wall of the water intake tank 7.

[0034] Specifically, when the nozzle 206 of the rectangular water spray frame 205 needs to be inspected and maintained, first, the fixation of the dovetail strip 203 by the fixing assembly 3 is released, and then the rectangular water spray frame 205 is pulled longitudinally. The rectangular water spray frame 205 drives the dovetail strip 203 to move longitudinally through the longitudinal plate 204, and the dovetail strip 203 slides along the dovetail groove 202 until the dovetail strip 203 is separated from the dovetail groove 202. At this time, the rectangular water spray frame 205 extends out from the inside of the water intake bin 7, which is convenient for manual observation of the nozzles 206 on the front, back and both sides of the rectangular water spray frame 205. Further, the rectangular water spray frame 205 is clamped by hand, and then the water pump 8 is started. The water pump 8 will prompt the nozzle 206 to spray water. The water spraying effect of the nozzle 206 on the front, back and both sides of the rectangular water spray frame 205 can be observed by naked eyes to judge the blockage of the nozzle 206. Then, the water pump 8 is turned off and the blocked nozzle 206 is disassembled and replaced, which is very convenient.

[0035] Embodiment 3:

[0036] The two fixing components 3 each include a fixing seat 301 and a through slot 306. The two fixing seats 301 are respectively fixedly arranged on both sides of the top of the slide plate 201. The tops of the two fixing seats 301 are provided with a receiving slot 302. One side of the two fixing seats 301 is provided with a slide slot 303. The inner walls of the two slide slots 303 are slidably connected with L-shaped blocks 304. A return spring 305 is fixedly arranged between the two L-shaped blocks 304 and the corresponding slide slots 303. The two through slots 306 are both provided on the surface of the slide plate 201. The inner walls of the two through slots 306 are slidably connected with T-shaped blocks 307. The backs of the two T-shaped blocks 307 are respectively slidably connected with the fronts of the two dovetail strips 203. The surfaces of the two T-shaped blocks 307 are provided with a slot engaged with the L-shaped block 304. The tops of the two T-shaped blocks 307 are fixedly provided with a pulling block 308.

[0038] Specifically, the extension of the return spring 305 will push the L-shaped block 304, and the L-shaped block 304 will be inserted into the slot to fix the T-shaped block 307. The back of the T-shaped block 307 will abut against the front of the dovetail strip 203, and the back of the dovetail strip 203 will be abutted by the inner wall of the back of the dovetail slot 202, so that the dovetail strip 203 can be fixed without using bolts to fix the dovetail strip 203. It is very convenient. By fixing the dovetail strip 203, the rectangular water spray rack 205 can be fixed. When the rectangular water spray rack 205 needs to be taken out from the inside of the water intake tank 7, 5, first pull the L-shaped block 304 horizontally, the L-shaped block 304 will compress the return spring 305 and disengage from the slot, releasing the fixation of the L-shaped block 304 to the T-shaped block 307, and then move the T-shaped block 307 upward to cause the T-shaped block 307 to disengage from the through slot 306 and slide into the interior of the receiving slot 302, thereby releasing the fixation of the dovetail strip 203 and the rectangular spray rack 205. There is no need to remove the bolts, which is very convenient. The fixing seat 301 will stabilize the T-shaped block 307 through the receiving slot 302 to prevent the T-shaped block 307 from being lost.

[0042] When in use, first pull the L-shaped block 304 horizontally, the L-shaped block 304 compresses the return spring 305 and disengages from the slot, thereby releasing the fixation of the L-shaped block 304 to the T-shaped block 307, and then move the T-shaped block 307 upward to cause the T-shaped block 307 to disengage from the through slot 306 and slide into the interior of the storage slot 302, thereby releasing the fixation of the dovetail strip 203 and the rectangular water spray frame 205, without the need to remove the bolts, which is very convenient, and then pull the rectangular water spray frame 205 longitudinally, the rectangular water spray frame 205 will drive the dovetail strip 203 to move longitudinally through the longitudinal plate 204, and the dovetail strip 203 will slide along the dovetail groove 202 until the dovetail strip 203 is disengaged from the dovetail groove 202, at which time the rectangular water spray frame 205 is released from the inner part of the water intake bin 7. The rectangular water spray frame 205 is extended to facilitate manual observation of the nozzles 206 on the front, back and both sides of the rectangular water spray frame 205. Further, the rectangular water spray frame 205 is clamped by hand and the water pump 8 is started.
