Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated pumping station technology, specifically a prefabricated pumping station with a dredging mechanism. Background Technology
[0002] The reference patent title is: A Prefabricated Pumping Station (Patent Publication No.: CN217811534U, Patent Publication Date: 2022.11.15), which includes a pumping station cylinder, a pipeline system, a control system, and a water pump system. The pumping station cylinder has an internal cavity. The control system is electrically connected to the pumping station cylinder. The pipeline system and the water pump system are located within the cavity and are both electrically connected to the control system. This design improves the pumping station's processing capacity by modifying the cylinder structure to be elliptical, allowing for the arrangement of more water pumps. Furthermore, the smaller minor diameter of the elliptical cylinder reduces the cargo height during horizontal transport, facilitating transportation.
[0003] Based on the aforementioned documents, prefabricated pumping stations are integrated devices widely used in municipal engineering, industry, and other fields for lifting and transporting liquids. During the operation of these pumping stations, the transported liquids often contain impurities such as silt and sand. Over time, this silt and sand accumulates at the bottom of the pumping station's inner cavity, affecting not only the normal operating efficiency of the pumping station but also potentially causing equipment damage and shortening its service life. Most existing prefabricated pumping stations lack effective dredging methods. Manual dredging is not only inefficient but also poses safety hazards. Some pumping stations with dredging functions have complex dredging structures, poor dredging effects, and are also inconvenient for cleaning and maintaining the components that filter impurities. Therefore, this utility model provides a prefabricated pumping station with a dredging mechanism. Utility Model Content

[0013] Beneficial effects
[0014] This utility model provides a prefabricated pumping station with a dredging mechanism. Compared with the prior art, it has the following advantages:
[0015] 1. This prefabricated pumping station with a sludge removal mechanism, by starting the water pump, introduces external water through the diversion pipe. The water flows through the connecting pipe into the annular pipe, and then is sprayed out from the sludge removal pipe to flush the silt at the bottom of the pumping station's internal cavity. The silt is then guided into the diversion pipe through the conical slot and guide channel. At this time, by starting the sludge discharge motor, the sludge discharge motor drives the feeding auger to rotate, transporting the silt collected in the guide pipe to the discharge pipe, and finally discharged outside the pumping station. By setting up sludge removal and discharge components, it can automatically flush and discharge the silt at the bottom of the pumping station's internal cavity, achieving good sludge removal effect without the need for manual sludge removal. The design of the conical slot and multiple sets of guide channels is conducive to the collection and flow of silt, which can further improve the sludge removal effect and quality of this prefabricated pumping station.
[0016] 2. This prefabricated pump station with a sludge removal mechanism moves the lifting screw upward by rotating the handwheel. The lifting screw then moves the connecting plate, filter basket, and positioning rod upward synchronously until the filter basket is removed. After cleaning the impurities inside the filter basket, the filter basket is reset so that it is placed back into the inner cavity of the baffle plate. The lifting assembly allows the filter basket to be easily raised and lowered, facilitating the cleaning of filtered impurities, ensuring the filtration effect of the filter basket, and also facilitating the maintenance and replacement of the filter basket.

[0043] When the prefabricated pumping station needs dredging, the water pump 815 is first started, and external water is introduced through the diversion pipe 816. The water flows through the connecting pipe 814 into the annular pipe 812, and then is sprayed out from the dredging pipe 813 to flush the mud and sand at the bottom of the inner cavity of the pumping station body 2. The mud and sand are then guided into the guide pipe 824 through the conical slot 6 and the guide channel 7. At this time, the dredging motor 821 is started, which drives the feeding auger 823 to rotate, thus removing the mud and sand collected in the guide pipe 824. The silt is transported to the sludge discharge pipe 822 and finally discharged outside the pump station body 2. When the prefabricated pump station has been working for a long time, the maintenance personnel can rotate the handwheel 42 to drive the lifting screw 43 to move upward. The lifting screw 43 will drive the connecting plate 44, the filter basket 5 and the positioning rod 9 to rise synchronously until the filter basket 5 is taken out. After cleaning the impurities in the filter basket 5, the filter basket 5 is reset so that the filter basket 5 is placed back in the inner cavity of the baffle plate 10.
