Description

Technical Field

[0001] This utility model relates to the field of interception wells, specifically a prefabricated interception well with automatic separation of rainwater and sewage. Background Technology

[0002] Interception wells are key structures in municipal drainage systems, primarily used at the end outlets of stormwater or combined sewer systems. Their core function is to effectively regulate and separate stormwater, sewage, or combined sewer systems. On sunny days, they can intercept all sewage in the sewer system and transport it to a sewage treatment plant for treatment, preventing sewage from being directly discharged into natural water bodies and causing pollution. During the rainy season, when the rainwater flow reaches a certain scale, they can directly discharge excess rainwater into natural water bodies, ensuring the smooth flow of the drainage system. They are important infrastructure for achieving stormwater and sewage separation, protecting the water environment, and improving urban drainage and flood control capabilities.

[0003] Most interception wells on the market currently follow a relatively fixed pattern in terms of structural design and functional implementation. Their core configuration consists of two submersible pumps installed inside the well shaft. The submersible pumps use their power to lift sewage from the pipe network to the sewage pipe network to complete the sewage interception operation. At the same time, to prevent garbage and debris from entering the well shaft and damaging the submersible pumps, a basket grid is usually installed at the water inlet inside the pump well. This basket grid uses physical interception to block garbage and debris from entering the interception well with the water flow, thereby providing basic protection for the submersible pumps and preventing damage to the submersible pump impeller due to debris entanglement and impact, thus maintaining the basic operational stability of the equipment.

[0004] However, in existing intercepting well designs, when rainwater flow is high, the submersible pumps, which are directly installed inside the well shaft without an effective water flow isolation structure, are directly impacted by the large flow of rainwater. Over time, this impact can cause cavitation inside the submersible pumps, leading to equipment damage. Furthermore, in the later stages of rainfall, the debris intercepted at the grates has accumulated to a certain volume, significantly increasing the difficulty of cleaning and further affecting drainage efficiency by clogging the grates' openings. This severely restricts the operational efficiency and stability of the municipal drainage system. Utility Model Content

The pump well divides its interior into a rainwater chamber and a sewage chamber. On non-rainy days, the combined rainwater and sewage in the rainwater chamber will flow into the sewage chamber through the diversion channel. On rainy days, when the rainfall is excessive, the rainwater will be discharged directly from the rainwater outlet pipe. Furthermore, the rainwater entering the pump well will impact the baffle plate, which buffers the impact of the rainwater, thereby reducing the impact of the rainwater entering the pump well on the sewage pump.

[0028] 2. This utility model, by setting up a partition, a diversion channel, and a basket grille, allows sewage to flow into the pump well through the municipal pipe network from the rainwater inlet pipe on non-rainy days. After entering the pump well, the sewage first enters the rainwater chamber. The sewage inside the rainwater chamber flows into the sewage chamber through the diversion channel set at the bottom of the partition. The basket grille set at the end of the diversion channel filters the impurities mixed in the sewage, preventing the impurities from clogging the sewage pump. Attached Figure Description

[0050] In specific operation: rainwater flows into the pump well 1 through the municipal pipe network from the rainwater inlet pipe 13. After entering the pump well 1, the rainwater first enters the rainwater chamber 7. The level gauge 25 detects the water level inside the pump well 1 and transmits the detection data to the control cabinet 24.

[0051] If the detected water level exceeds the set level, the hydraulic gate 20 at one end of the rainwater outlet pipe 14 will automatically open upon receiving the instruction from the control cabinet 24. At the same time, the sewage pump 15 inside the sewage tank 8 will also stop operating, and the rainwater flowing into the pump well 1 will be discharged directly into the river through the rainwater outlet pipe 14.

[0052] If the water level detected by the level gauge 25 does not exceed the set level, the sewage flows into the sewage tank 8 through the gap between the bottom of the partition 10 and the rainwater tank 7. As the sewage enters the sewage tank 8, it passes through the basket grille 22, which filters and collects impurities in the sewage. At the same time, the hydraulic gate 20 is in a closed state. After the sewage enters the sewage tank 8, it is transmitted by the two sewage pumps 15 in the sewage tank 8 through the pressure pipeline 16 to the sewage outlet main pipe 19. Finally, the sewage is discharged into the municipal sewage network through the sewage outlet main pipe 19.
