[0023] The implementation principle of the aquaculture sewage pumping pretreatment device of the present embodiment is as follows: when the sewage needs to be pumped for pretreatment, the operator fixes the device on the bottom of the aquaculture pond through the support rod 2, so that the bottom of the pumping box 1 contacts the sewage, and at this time the sewage will enter the water guide box 304 through the water inlet groove opened at the bottom of the pumping box 1, and the sewage can be preliminarily filtered by the filter net 309 installed inside the water inlet groove. At this time, the motor 301 is started to drive the rotating rod 302 to rotate, and the rotating rod 302 rotates through the belt 315 to transmit the sewage. The rotation of the rotating rod 316 drives the spiral blade 317 to rotate, and the rotation of the rotating rod 316 drives the spiral blade 317 to rotate. The spiral blade 317 can extract the sewage inside the water guide box 304, so that the sewage can be extracted from the water guide box 304 to the mounting plate 1 318, and the impurities in the sewage can be filtered by the filter screen 2 319 installed on the inner side of the mounting plate 1 318. As the rotating rod 1 302 rotates, the squeezing rod 1 303 rotates, and the squeezing plate 307 can be squeezed to slide on the guide rod 305 through the squeezing plate 30 The sliding of the squeezing plate 307 can squeeze the spring 308 and the sewage inside the water guide box 304, thereby increasing the flow rate of the sewage in the water guide box 304, thereby better performing the extraction work. The squeezing plate 307 slides to drive the connecting plate 310 to move, and the movement of the connecting plate 310 can indirectly drive the cleaning roller 312 to move. The movement of the connecting plate 310 can drive the gear 313 to move on the rack 314, and because the gear 313 and the rack 314 are in a meshing state, the gear 313 can move on the rack 314. The gear 313 drives the rotating rod 311 to rotate, and the rotating rod 311 drives the cleaning roller 312 to rotate, so that the cleaning roller 312 can move and rotate, and then the impurities in the sewage at the bottom of the pumping tank 1 can be stirred and cleaned, and the blockage can be effectively prevented. When the cleaning roller 312 moves to the bottom of the filter screen 309, the filter screen 309 can be cleaned, and the blockage of the filter screen 309 can be effectively prevented, so that the pumping work can be better performed, thereby improving the working efficiency of the sewage pumping pretreatment device; When it is necessary to pre-treat the sewage by pumping, the operator fixes the device on the bottom of the breeding pond through the support rod 2, so that the bottom of the pumping box 1 contacts the sewage. At this time, the sewage will enter the water guide box 304 through the water inlet groove opened at the bottom of the pumping box 1, and the sewage inside the breeding pond will be extracted and filtered through the filtering mechanism 3. As the squeezing rod 1 303 rotates, the squeezing plate 307 slides to drive the squeezing rod 2 404 to move. Through the movement of the squeezing rod 2 404, it can squeeze and contact with one side of the connecting plate 2 403, and then drive the connecting plate 2 403 to move. Through the movement of the connecting plate 2 403, the telescopic rod 405 is extended and retracted, and the spring 2 406 can be squeezed, so as to increase the stability of the connecting plate 2 403 when moving. As the connecting plate 2 403 moves, the moving plate 402 is driven to slide inside the fixed plate 2 401. The sliding of the moving plate 402 can indirectly drive the scraper 408 to move. As the moving plate 402 continues to slide, the travel switch 41 can be squeezed 3. When the travel switch 413 is squeezed, the electromagnet 2 411 can be controlled to be closed. At this time, the scraper 408 can be reset by the elastic force of the torsion spring, so that the scraper 408 is straightened. When the squeezing plate 307 is reset, the connecting plate 2 403 can be driven to reset, and then the scraper 408 can be reset. The impurities accumulated on the filter screen 2 319 can be pushed by the reset of the scraper 408, and the impurities can be pushed into the collection box 501 for storage. As the scraper 408 is reset, it can contact with one end of the blocking rod 412, and the blocking rod 412 can squeeze the scraper 408 to rotate. The movable rod 407 is driven to rotate by the rotation of the scraper 408, so that the electromagnet 1 409 and the electromagnet 2 411 can be contacted, and then the scraper 408 can be limited and fixed, so that the sewage can be collected in cooperation with the filtering mechanism 3, and the filter screen 2 319 can be effectively prevented from being blocked, which makes it more convenient to collect impurities, and further improves the working efficiency of the sewage pumping pretreatment device. When it is necessary to pre-treat the sewage by pumping, the operator will fix the device on the bottom of the breeding pond through the support rod 2, so that the bottom of the pumping box 1 is in contact with the sewage. At this time, the sewage will enter the water guide box 304 through the water inlet groove opened at the bottom of the pumping box 1, and the sewage inside the breeding pond will be extracted and filtered by the filtering mechanism 3, and the cleaning mechanism 4 will be used to clean the filter screen 319 and collect the impurities on the filter screen 319. At this time, the impurities cleaned by the scraper 408 can be collected by installing the collecting box 501, and the sewage entering can be discharged through the collecting box 501. Impurities can be collected and stored in the collecting box 501 by discharging through the water outlet holes opened on both sides of the collecting box 501, which is convenient for subsequent operators to handle. By installing the fixing sleeve 502, the rotating rod 302 can be fully protected to effectively prevent impurities from affecting the rotation of the rotating rod 302. By starting the treatment pump 504 installed on the inner side of the mounting plate 503, the filtered sewage can be extracted and transported to the sewage treatment system for treatment through the water pipe 505, which makes it more convenient for operators to use and improves the convenience of the sewage pumping pretreatment device.
