Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology and relates to a multi-point attached water quality detection device for wastewater treatment plants. Background Technology

[0002] Municipal sewage and industrial wastewater contain large amounts of heavy metal ions, organic pollutants, pathogenic microorganisms, and nutrients such as nitrogen and phosphorus, requiring treatment at sewage treatment plants. Sewage treatment plants generally employ online monitoring systems to control the treatment process, continuously monitoring water levels and quality within the sewage tanks and uploading this information to the sewage treatment analysis system. Currently, water level monitoring typically uses electronic water level gauges attached to the walls of the sewage tanks. These gauges contain a microcontroller and multiple water level sensors, enabling real-time monitoring of the water level and digitizing the data before uploading it to the system via wired or wireless means. However, water quality monitoring often uses handheld water quality analyzers. This involves sampling sewage and dripping it into the analyzer, requiring frequent operation by staff and consuming significant manpower. Furthermore, each test can only measure water quality parameters at a single level and time period, failing to provide real-time monitoring of water quality changes or reflect longitudinal water quality gradients at different depths within the sewage treatment tank, thus hindering the provision of real-time data to the sewage treatment analysis system platform. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a multi-point attached water quality testing device to achieve real-time monitoring of water quality in sewage tanks.

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

[0005] A multi-point attached water quality monitoring device is characterized by comprising an electronic water level gauge and multiple water quality monitoring boxes; the electronic water level gauge contains a microcontroller and a water level sensor; each water quality monitoring box includes a housing, within which a water quality detection probe is fixedly installed, a water inlet is provided at the bottom of the housing, and an vent is provided at the top of the housing; multiple water quality monitoring boxes are arranged at regular intervals along the longitudinal direction of the electronic water level gauge, each water quality monitoring box is fixed to the electronic water level gauge by screws, and the data lines of the water quality detection probes in each water quality monitoring box converge with the data lines of the water level sensors in the electronic water level gauge to form a data bus connected to the data interface of the microcontroller.

[0006] This invention utilizes the existing electronic water level gauge structure to attach multiple water quality detectors to the electronic water level gauge. The water quality detection probes use the wiring channels of the existing water level sensor inside the electronic water level gauge and a microcontroller to transmit water quality signals to the microcontroller for processing and then send them to the backend system. This allows for real-time monitoring of both the water level and water quality in the sewage tank, saving manpower and enabling the monitoring of water quality at different depths within the sewage tank, reflecting the gradient changes in water quality within the sewage tank, and providing detailed data information for the sewage treatment and monitoring system.

[0013] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this utility model includes an electronic water level gauge 1 and multiple water quality testing boxes 2; the electronic water level gauge 1 is equipped with a microcontroller and a water level sensor; each water quality testing box 2 includes a housing 21, a water quality testing probe 22 is fixedly installed inside the housing 21, a water inlet hole 23 is provided at the bottom of the housing 21, and an exhaust hole 24 is provided at the top of the housing; multiple water quality testing boxes 2 are arranged at certain intervals along the longitudinal direction on the electronic water level gauge 1, and each water quality testing box 21 is fixed to the electronic water level gauge 1 by screws 25. The data lines 3 of the water quality testing probes in each water quality testing box converge with the data lines of the water level sensors in the electronic water level gauge to form a data bus and connect to the data interface of the microcontroller.

[0014] In a specific implementation of this utility model, in order to facilitate installation and fixation on the wall of the sewage tank, a wing plate 4 can be extended from both sides of the back plate of the electronic water gauge in a direction parallel to the back plate surface. The thickness of the wing plate is less than the thickness of the electronic water gauge.

[0015] In use, this invention can be fixed to the sewage tank wall with bolts using the wing plates on both sides of the electronic water gauge. To facilitate installation and disassembly and ensure a secure installation, mounting slots can also be pre-set on the sewage tank wall, allowing the electronic water gauge to be directly inserted into the slots.

[0016] like Figure 5 As shown, during the construction of sewage tank 5, slots 6 can be set longitudinally on the tank wall. The cross-sectional shape of the slot is T-shaped, and there are limiting grooves on both sides, which match the cross-section of the electronic water gauge with wing plates.

[0017] like Figure 6 As shown, when the present invention is inserted into the slot, the wing plates 4 on both sides of the electronic water level gauge 1 are respectively inserted into the limiting grooves on both sides of the slot 6 on the sewage tank wall, which can keep the electronic water level gauge in a fixed position. When sewage 7 is injected or discharged into the sewage tank 5, the water level sensor in the electronic water level gauge 1 can send the water level signal to the microcontroller as the water level in the sewage tank changes. The detection probe in each water quality detection box 2 below the water level line also sends the detected water quality information and its position information to the microcontroller. The microcontroller converts the analog signal sent by the sensor into a digital signal and sends it to the remote control center or other data receiving device via wired or wireless means.
