Technical Field

[0001] The utility model relates to the technical field of underground prefabricated pump stations, in particular to an underground prefabricated pump station. Background Art

[0002] A prefabricated pump station is an integrated device that combines a submersible pump, pump station equipment, decontamination screen equipment, control system, and remote monitoring system. It is highly integrated: the prefabricated pump station integrates multiple devices into a single cylinder, resulting in a compact structure and small footprint, reducing on-site construction workload and construction cycle. It is also highly reliable: factory-produced, using advanced production processes and quality control systems, ensures stable and reliable product quality. The cylinder is usually made of high-strength fiberglass or stainless steel, featuring corrosion resistance, wear resistance, and high strength.

[0003] Some existing underground prefabricated pump stations require users to climb up and down using ladders when installing and maintaining equipment inside the prefabricated pump stations. The tanks are tightly sealed, resulting in poor air circulation and the generation of harmful gases. Therefore, the sealed doors must be opened to allow air in and out.

[0004] The traditional underground prefabricated pump station has the following problems: when installing and maintaining the equipment inside the prefabricated pump station, workers may accidentally slip and get injured due to the influence of running water when climbing up and down the escalator. At the same time, harmful gases are generated inside the tank and cannot be discharged quickly. For this reason, we propose an underground prefabricated pump station. Utility Model Content
