Description

Technical Field

[0001] The utility model relates to a modular interception pump station and belongs to the technical field of drainage pipeline engineering. Background Art

[0002] At present, interception pump stations play a vital role in the design and implementation of urban drainage systems. When faced with the initial rainfall, the washing effect of rainwater will cause it to quickly absorb automobile exhaust, industrial waste gas and pollutants dissolved on the road surface in the atmosphere. If such pollutant-rich rainwater flows into rivers or lakes without management, it will inevitably cause great pollution to the water environment. For this reason, the construction and operation of interception pump stations are extremely critical. Their main responsibility is to treat the initial rainwater with high concentrations of pollutants into the sewage pipeline.

[0003] After searching the prior art, it was found that a Chinese patent with the publication number CN220336089U disclosed a flow-cutting pump station. In the patent, the installation chamber is adjacent to the well body through a wall. During the on-site construction process, it was found that the use of an integrated flow-cutting pump station is prone to greater restrictions due to the irregular site restrictions. Summary of the invention

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a modular interception pump station which can be flexibly arranged according to the site conditions.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a modular interception pump station, comprising:

[0006] An intercepting well, wherein the intercepting well is provided with a water inlet and a water outlet, and a liquid storage cavity is provided in the intercepting well;

[0007] At least one submersible sewage pump, the submersible sewage pump is provided with a pump water inlet and a pump water outlet, the submersible sewage pump is installed in the interception well, and the pump water inlet of the submersible sewage pump is arranged in the liquid storage cavity of the interception well;

[0008] A valve well, wherein a drain pipe and a valve installed on the drain pipe are arranged in the valve well;

[0009] The pump outlet of the submersible sewage pump is connected to the drain pipe;

[0010] A gate is arranged on the water outlet of the intercepting well, and the gate is suitable for controlling the water outlet of the water outlet.

[0011] Furthermore, in order to reduce the kinetic energy of water, the modular interception pump station further comprises a stilling well, wherein the stilling well is provided with a stilling well water inlet and a stilling well water outlet;

[0012] The water inlet of the stilling well is connected to the drainage pipe of the valve well.

[0013] Furthermore, the modular interception pump station further comprises a flow meter well, wherein the flow meter well is provided with a flow meter well water inlet and a flow meter well water outlet;

[0014] The flow meter well is installed between the valve well and the stilling well;

[0015] The water inlet of the flow meter well is connected to the drainage pipe through a pipeline, and the water outlet of the flow meter well is connected to the water inlet of the energy dissipation well through a pipeline.

[0016] Furthermore, in order to facilitate the opening and closing of the gate, the modular interception pump station further includes a hoist, which is installed above the interception well;

[0017] The hoist is transmission-connected to the gate, and the hoist is suitable for controlling the opening and closing of the gate.

[0018] Further, in order to facilitate the control of the submersible sewage pump, the modular interception pump station further includes a controller and at least one liquid level sensor, and the liquid level sensor is arranged in the interception well;

[0019] The controller is electrically connected to the liquid level sensor and the submersible sewage pump respectively;

[0020] The controller is suitable for controlling the action of the submersible sewage pump according to the signal received from the liquid level sensor.

[0021] Furthermore, the modular intercepting pump station also includes a check valve, which is arranged on the drainage pipe in the valve well.

[0022] Furthermore, a specific type of check valve is provided, wherein the check valve is a clamp-type duckbill valve.

[0023] Furthermore, in order to avoid clogging of the intercepting well, a grid is provided on the water inlet of the intercepting well.

[0024] Furthermore, in order to provide a safety protection, a fence is provided on the intercepting well.

[0025] By adopting the above technical solution, the utility model has the following beneficial effects:

[0026] In the utility model, under normal circumstances without rain, the gate remains closed. At this time, sewage flows into the liquid storage chamber of the intercepting well through the water inlet, and is then pumped by a submersible sewage pump and discharged into the sewage network connected to the drain pipe. In the early stage of rainfall, the gate remains closed. At this time, rainwater and sewage are discharged into the sewage network together by the submersible sewage pump. When the rainfall increases to a certain level, the gate will open so that rainwater can be directly discharged through the outlet of the intercepting well. By installing the intercepting well and the valve well separately, they can be flexibly arranged according to the specific conditions on site during the installation process, which improves the applicability and flexibility of the intercepting pump station and facilitates necessary expansion or transformation according to actual conditions.

[0027] In addition, the energy dissipation well can effectively reduce the kinetic energy of the water flow and reduce the impact on the drainage network. The configuration of the flow meter well makes it easier to monitor and adjust the water flow. The combination of the liquid level sensor and the controller realizes the precise control of the submersible sewage pump, greatly improving the convenience and efficiency of operation. At the same time, the setting of the grid effectively filters the impurities in the inflowing sewage, and the existence of the fence provides the necessary safety protection for the interception well.

[0028] In summary, the utility model has not only been significantly improved in adaptability, making it easy to adjust and optimize according to actual needs, but also greatly improved the efficiency and reliability of the drainage system through precise water flow control and effective safety protection measures.
