[0040] Referring to Figure 1 and Figure 4The end of the quick fixing mechanism 12 away from the water outlet pipe 9 is fixedly connected with a mounting pipe 10. The mounting pipe 10 is arranged to facilitate the sewage discharged by the automatic sewage pump to be connected to other places for next treatment. The water outlet pipe flange 1201 is fixedly connected to the outer wall of the rear end of the water outlet pipe 9. The mounting pipe flange 1202 is fixedly connected to the outer wall of the front end of the mounting pipe 10. The water outlet pipe 9 and the mounting pipe 10 are fixed by the water outlet pipe flange 1201 and the mounting pipe flange 1202.

[0041] With reference to Figure 1 , Figure 4 and Figure 5 , the inner wall of the limiting groove 1203 is fixedly connected with a plurality of reset springs 1205. The reset springs 1205 are arranged to facilitate the clamping of the limiting block 1204 by the clamping plate 1206 and reset the clamping plate 1206 when the two flanges are separated. One end of the reset spring 1205 close to the middle of the inner wall of the limiting groove 1203 is fixedly connected with the clamping plate 1206. The clamping plate 1206 is arranged to facilitate the clamping of the limiting block 1204, thereby fixing the two flanges. The front end of the mounting pipe 10 is sleeved with a gasket 1207.

[0043] Working principle: When the automatic sewage pump works, the motor on the pump body 1 starts to drive the main shaft 5 to rotate, thereby driving the impeller 6 and the connecting rod 7 to rotate. The rotation of the impeller 6 generates suction to suck the sewage from the filter hole 3 and discharge the sewage through the water outlet pipe 9. The rotation of the connecting rod 7 drives the scraper 8 to rotate, thereby scraping off the accumulated impurities on the inner wall of the protective cover 2 to avoid the accumulation of impurities in the sewage pump, thereby reducing the sewage discharge efficiency. When the water outlet pipe 9 and the mounting pipe 10 need to be connected, the water outlet pipe flange 1201 and the mounting pipe flange 1202 are butt-jointed. The limiting block 1204 on the mounting pipe flange 1202 is aligned with the limiting groove 1203 on the water outlet pipe flange 1201. The reset spring 1205 in the limiting groove 1203 drives the clamping plate 1206 to fix the limiting block 1204, thereby fixing the two flanges. At the same time, the gasket 1207 sleeved on the front end of the mounting pipe 10 enters the inner wall of the water outlet pipe 9 to seal the pipe body, thereby ensuring the tightness of the connection between the water outlet pipe 9 and the mounting pipe 10.
