Description

Technical Field

[0001] This utility model relates to the field of urban drainage system technology, and in particular to a rainwater and sewage control system based on online monitoring. Background Technology

[0002] In traditional urban drainage systems, rainwater and sewage typically share the same pipe network, leading to mixed sewage overflows and environmental pollution during the rainy season, or causing sewage treatment plants to operate beyond their capacity. Existing technologies, such as some separation systems, rely on manual judgment or fixed water level threshold control, resulting in delayed response and an inability to dynamically adapt to changes in water quality. Current rainwater and sewage separation control systems lack integrated water quality monitoring functions, making it impossible to accurately distinguish between rainwater and sewage, leading to low separation efficiency. Therefore, there is an urgent need for a rainwater and sewage separation system that combines multi-parameter online water quality monitoring and intelligent control to achieve efficient and environmentally friendly drainage management. Utility Model Content

[0003] This application addresses the shortcomings of the prior art by providing a rainwater and sewage control system based on online monitoring. It uses multiple sensors to monitor water quality and level in real time, and combines the main control module to dynamically control the start and stop of sewage pumps and rainwater pumps, thereby achieving precise separation of rainwater and sewage. At the same time, it adopts a concealed pump station design to reduce the occupation of urban road space.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A stormwater and sewage control system based on online monitoring includes a submerged pumping station pre-embedded at a stormwater collection point on an urban road, and a control cabinet installed above the nearby ground. Multiple sensors are installed below the water level in the submerged pumping station. A main control module is installed inside the control cabinet. A sewage discharge drive component is installed at the low water level of the submerged pumping station, and a rainwater drive component is installed at the middle water level. The sewage discharge drive component and the rainwater drive component are signal-connected to the main control module and are activated by signals sent by the main control module. All sensors are signal-connected to the main control module to monitor the water level and water quality of the submerged pumping station in real time.

[0006] Furthermore, a PE pipe is vertically installed from the top cover to the bottom of the sunken pump station. A cable is threaded through the PE pipe. One end of the cable is connected to the control cabinet, and the other end is connected to a detection probe. Multiple detection components are integrated on the detection probe.

[0007] Furthermore, the detection device includes an integrated COD sensor, an SS suspended matter sensor, a turbidity sensor, and a conductivity sensor.

[0008] Furthermore, the sewage discharge drive assembly includes a sewage pump arranged in the submerged pumping station, the outlet of which is connected to a sewage pipe extending from the bottom to the top outlet of the submerged pumping station.

[0009] Furthermore, the rainwater drive assembly includes a rainwater pump located at the middle of the water level in the submerged pumping station, and the outlet of the rainwater pump is connected to a drain pipe that extends from the bottom to the top outlet of the submerged pumping station.

[0010] Furthermore, the control cabinet is also equipped with a communication module, which sends and receives signals to and from external clients.

[0011] Furthermore, the PE pipe is fixed to the wall of the submerged pumping station by setting U-shaped pipe clamps.

[0012] The advantages of this utility model over the prior art are as follows:

[0013] This invention uses multi-parameter water quality sensors to monitor the sewage index in the pipeline in real time, enabling intelligent switching between sewage pumps and rainwater pumps. The system can automatically adjust its operating strategy according to different working conditions such as sunny days, early rain, and the rainy season, reducing energy consumption while ensuring the interception effect, achieving precise diversion, and reducing the load on sewage treatment plants and the risk of water pollution. Moreover, the sunken pump station is installed discreetly, avoiding the occupation of road space. It also supports remote monitoring, which can reduce operation and maintenance costs, and has significant practicality and economy. Attached Figure Description

[0017] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0018] like Figures 1 to 2 As shown, this utility model provides a rainwater and sewage control system based on online monitoring, which aims to solve the problem that existing urban rainwater and sewage control systems do not integrate water quality monitoring functions, cannot accurately distinguish between rainwater and sewage, and thus have low diversion efficiency.

[0019] In one embodiment of this utility model, the sunken pump station 1 is pre-buried in the rainwater collection point of the urban road, with an openable cover on the top, and the bottom and side walls are made of concrete or high-density polyethylene (HDPE) material, forming a water storage cavity inside.

[0020] In one embodiment of this utility model, the control cabinet 2 is located on the ground near the sunken pump station 1 and contains a main control module (such as a PLC or embedded controller), a power supply module, and a communication module. The enclosure of the control cabinet 2 meets the IP65 protection rating and is suitable for outdoor environments.

[0021] In one embodiment of this utility model, the detection component is disposed within the submerged pumping station 1 and includes:

[0022] Water level sensor: Installed on the side wall of the pumping station, using ultrasonic or pressure sensors to monitor the water level in real time.

[0023] Water quality sensor group: integrated into the detection probe 3 (such as a multi-parameter water quality analyzer), including COD sensor, SS suspended solids sensor, turbidity sensor and conductivity sensor, and connected to the control cabinet 2 via cable 8.

[0024] In one embodiment of this utility model, the detection probe 3 is connected to the main control module through a cable 8 (such as an RS485 communication cable 8) that passes through a PE pipe 4. The PE pipe 4 is vertically fixed to the pump station wall and fixed at intervals of 0.5-1m by U-shaped pipe clamps 9 to ensure the protection of the cable 8 and the convenience of maintenance. The bottom of the PE pipe 4 has multiple water passage holes 7 (the number is not limited and can be 10-20).

[0025] In one embodiment of this utility model, the driving component is a sewage driving component 6, which is located in the low water level area of ​​the pumping station and includes a sewage pump 61 (such as a submersible centrifugal pump) and a sewage pipe 62, the outlet of which extends to the municipal sewage pipe network.

[0026] In one embodiment of this utility model, the rainwater drive component 5 is located in the middle water level zone of the pumping station and includes a rainwater pump 51 and a drainage pipe 52. The outlet of the drainage pipe 52 is connected to the rainwater discharge channel.

[0027] In one embodiment of this utility model, both components are connected to the main control module via frequency converters to receive start / stop and speed adjustment commands.

[0028] It should be noted that the various hardware components involved in this utility model can be selected according to the actual situation. Specific sensor models (such as HACH COD analyzers), pump power, and communication protocols (such as Modbus RTU) are not limited here.

[0029] Working Principle: Data Acquisition: The water level sensor and water quality sensor group collect real-time data on water level, COD, SS, turbidity, and conductivity within the pumping station and transmit it to the main control module. Mode Judgment: The main control module determines the water quality type based on a preset algorithm (such as threshold comparison or machine learning model): If COD > 200 mg / L and SS > 100 mg / L, it is determined to be sewage, triggering the start of sewage pump 61; if the water quality parameters are below the threshold and the water level reaches the set height, it is determined to be rainwater, triggering the start of rainwater pump 51. Execution Control: The main control module dynamically adjusts the pump operating frequency according to the rise and fall of the water level. When the water level exceeds the limit, an alarm is triggered, and a warning message is sent to the management platform via a communication module (such as a 4G / NB-IoT module).

[0030] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
