Description

Technical Field

[0001] This utility model relates to the technical field of online water quality monitoring equipment, specifically a water-saving multi-parameter online water quality monitoring and control device. Background Technology

[0002] With the development of society and the economy and the improvement of people's living standards, increasingly higher requirements have been placed on the quality of tap water supply. To achieve this, multi-parameter water quality monitoring technology for tap water supply networks has emerged, serving as a powerful means to ensure that tap water supply quality meets standards. Traditionally, this method largely relies on large-scale external drainage for water quality testing, which leads to a significant waste of water resources. This is detrimental to building a resource-saving society and hinders water companies from controlling the production-sales gap, and therefore requires improvement. Utility Model Content

[0003] One of the technical problems to be solved by this application is to overcome the defects of the above-mentioned related technologies and provide a water-saving multi-parameter online water quality monitoring and control device.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: a water-saving multi-parameter online water quality monitoring and control device, including a controller, a communication module for uploading water quality monitoring data, and a filter, a pressure reducing valve, a first solenoid valve, and a water quality analysis module for measuring multiple water quality parameters connected in sequence on the measuring water circuit. The communication module, the first solenoid valve, and the water quality analysis module are electrically connected to the controller, and a constant flow limiting device is provided between the water quality analysis module and the drain pipe.

[0005] Compared with related technologies, this application has the following advantages: by reducing the basic water flow rate during the water quality detection process through a pressure reducing valve and a constant flow limiting device, the water quality analysis module is ensured to work under appropriate water pressure, resulting in accurate measurements and extended service life. Furthermore, a first solenoid valve is installed in the measurement water circuit, which is closed during measurement intervals to completely stop the water flow, further reducing water sample consumption.

[0006] Preferably, the constant current limiting device is a throttle valve.

[0007] As an improvement, a cleaning bypass is connected between the water quality analysis module and the drain pipe. A second solenoid valve is installed on the cleaning bypass, and this second solenoid valve is electrically connected to the controller. This can be used to flush the measurement water path during measurement intervals, stabilizing measurement accuracy. The flushing wastewater is mainly discharged from the cleaning bypass at a relatively fast rate.

[0008] Preferably, the water quality analysis module includes a measuring chamber connected to the measuring water circuit and various types of water quality sensors and interconnects connected to each interface of the measuring chamber. The various types of water quality sensors are electrically connected to the controller via the interconnects. This modular design reduces maintenance difficulty, enables rapid repairs, and avoids periods of downtime in water quality monitoring.

[0009] Preferably, the controller is an RTU. An RTU is a low-power remote terminal control unit that can be powered by a battery, eliminating the need for wiring and reducing costs.

[0010] Preferably, one side of the housing is equipped with a quick-connect water inlet, which is connected to the filter via a flexible hose; the other side of the housing is equipped with a first quick-connect water outlet and a second quick-connect water outlet, which are connected to the measuring chamber via a T-joint. A throttling valve is connected between the T-joint and the first quick-connect water outlet, and a second solenoid valve is connected between the T-joint and the second quick-connect water outlet. This facilitates the upgrading and renovation of existing water supply network monitoring systems. Attached Figure Description

[0015] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0016] This implementation example Figure 2 and Figure 3 The image shows a water-saving multi-parameter online water quality monitoring and control device, including a battery 1 and a controller 2 installed in the upper part of the housing 11, a communication module for uploading water quality monitoring data, a filter 3, a pressure reducing valve 4, a first solenoid valve 5, and a water quality analysis module 6 for measuring multiple water quality parameters, arranged in the lower part of the housing 11 and connected in sequence to the measuring water path. The communication module, the first solenoid valve 5, and the water quality analysis module 6 are electrically connected to the controller 2, and a constant flow limiting device is provided between the water quality analysis module 6 and the drain pipe.

[0017] In this embodiment, as Figure 4 As shown, the controller 2 is an RTU, namely a remote terminal control unit, which can be connected to a wired network via a serial port, or connected to a mobile APP of nearby water quality monitoring and management personnel via Bluetooth, or upload water quality monitoring data to the water quality monitoring platform via other wireless communication modules; the constant flow limiting device is a throttle valve 8, and the communication module includes an antenna 10 installed outside the housing 11.

[0018] The water quality analysis module 6 is connected to the drainage pipe by a cleaning bypass, and a second solenoid valve 7 is provided on the cleaning bypass. The second solenoid valve 7 is electrically connected to the controller 2.

[0019] The water quality analysis module 6 includes a measuring chamber (not shown in the figure) connected to the measuring water path, and various types of water quality sensors and a hub line 9 connected to each interface of the measuring chamber. The various types of water quality sensors are electrically connected to the controller 2 via the hub line 9. These sensors include residual chlorine sensors, pH sensors, turbidity sensors, and conductivity sensors. Here, the measuring chamber is a flow cell formed by assembling multiple sensor mounting bases. The number of sensor mounting bases can be increased or decreased according to the number of water quality parameters to be detected.

[0020] In this embodiment, a quick-connect water inlet 12 is provided on one side of the housing 11. The quick-connect water inlet 12 is used to connect the sample inlet tube and is connected to the filter 3 through a flexible tube. On the other side of the housing 11, a first quick-connect water outlet 13 and a second quick-connect water outlet 14 are provided. The first quick-connect water outlet 13 and the second quick-connect water outlet 14 are connected to the measuring chamber through a three-way connector (not shown in the figure). The throttle valve 8 is connected between the three-way connector and the first quick-connect water outlet 13, and the second solenoid valve 7 is connected between the three-way connector and the second quick-connect water outlet 14.

[0021] like Figure 1 As shown, during measurement, the RTU controls the opening of the first solenoid valve 5, and the RTU supplies power to the residual chlorine sensor, pH sensor, turbidity sensor, and conductivity sensor. The chamber is filled with sample water, which flows slowly in a small amount under the action of the throttling valve 8. The residual chlorine sensor, pH sensor, turbidity sensor, and conductivity sensor measure accurate water quality parameters. During the measurement interval, the RTU controls the closing of the first solenoid valve 5, so that the water flow into the measurement chamber completely stops. During the measurement interval, when periodic flushing is required, the RTU controls the opening of the first solenoid valve 5 and the second solenoid valve 7. The flushing water is discharged from the throttling valve 8 and the cleaning bypass to the drain pipe, mainly discharged from the cleaning bypass at a relatively fast flow rate.

[0022] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
