Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology. Background Technology

[0002] Water supply networks are the main channels for delivering drinking water. The water quality in the network directly affects whether end users can access clean and qualified water. To ensure that the water quality at the end of the water supply network meets national drinking water safety standards, it is necessary to monitor the water quality in the network in real time.

[0003] The sensing end of the sensor module is the core of water quality parameter detection. Rust, biofilm, suspended impurities and other substances in the water supply network can easily adhere to the surface of the sensing end, causing the detection signal to drift and the response speed to slow down. Therefore, the sensor module needs to be cleaned and maintained regularly. However, the process of removing the sensor module from the water supply network in the existing device is complicated and requires the water supply network to be shut down during the removal process.

Detailed Implementation

[0016] Please see Figures 1-2 ,in, Figure 1 This is a schematic diagram of the multi-parameter online water quality monitoring device for water supply networks according to this utility model. Figure 2 This is a cross-sectional view of the multi-parameter online water quality monitoring device for water supply networks according to this utility model.

[0017] This utility model provides a multi-parameter online water quality monitoring device for a water supply network, including a pipe body 101, a connecting module, a connecting component, a monitoring module, and a main control module. The connecting module includes a fixing base 102 disposed on the outer wall of the pipe body 101. A monitoring cylinder 104 is disposed on a platform above the fixing base 102. An inlet pipe 103 and an outlet pipe 105 are respectively connected to the two ends of the monitoring cylinder 104. One end of the inlet pipe 103 and one end of the outlet pipe 105 are respectively welded to the two ends of the pipe body 101 and connected. A solenoid valve 106 for controlling water flow is disposed on the outlet pipe 105. The monitoring cylinder 104 and the main control module are connected to the main control module. A connecting pipe 107 is welded between the water outlet pipes 105; the connecting assembly includes a threaded cylinder 108 fixed above the monitoring cylinder 104, the inner wall of the threaded cylinder 108 is threaded, and a mounting post 110 adapted to its thread is provided above it, and a mounting plate 111 is fixed on the mounting post 110; the monitoring module is disposed on the mounting plate 111, and the sensing end of the monitoring module passes through the mounting plate 111 and the mounting post 110 and extends into the monitoring cylinder 104; the main control module is disposed on one side of the fixed base 102, and the main control module is electrically connected to the monitoring module and the solenoid valve 106 respectively. The main control module consists of a main controller, a communication module and a drive unit;

[0018] Main controller: It adopts STM32F407ZGT6 microprocessor, which has strong computing performance and low power consumption. It is suitable for calculating the data collected by the monitoring module and meets the long-term continuous operation requirements of pipeline monitoring.

[0019] Communication Module: Integrates a SIM868 4G module and a MAX485 communication chip. The 4G module supports remote data upload to the monitoring platform, adapting to outdoor pipeline network scenarios without wired networks; the MAX485 chip enables RS485 wired communication, compatible with existing monitoring networks in water systems, ensuring data transmission stability.

[0020] Drive unit: ULN2003 Darlington tube array is used to drive the solenoid valve 106 on the water outlet pipe 105 to realize automatic control of the water level in the monitoring cylinder 104; equipped with LM1117-3.3V voltage regulator chip to provide stable power supply for each sensor and control circuit.

[0021] Furthermore, the solenoid valve 106 is disposed between the monitoring cylinder 104 and the connecting pipe 107 and the outlet pipe 105.

[0022] In this embodiment, when the monitoring device is working, the solenoid valve 106 is in the closed state. At this time, the water flowing into the monitoring cylinder 104 flows back into the pipe body 101 through the connecting pipe 107. The water level in the monitoring cylinder 104 is high, and the sensing end of the monitoring module is submerged in water. When the monitoring module needs to be disassembled for maintenance, the solenoid valve 106 is opened. At this time, the water in the monitoring cylinder 104 will flow back into the pipe body 101 through the water outlet pipe 105, and the water level in the monitoring cylinder 104 will drop, ensuring that no water splashes out from the top of the monitoring cylinder 104 after the mounting column 110 is disassembled.

[0023] Furthermore, the monitoring module includes a pH sensor 112, a dissolved oxygen sensor 113, and a conductivity sensor 114. The pH sensor 112, the dissolved oxygen sensor 113, and the conductivity sensor 114 are respectively disposed on the mounting plate 111, and the sensing end passes through the mounting plate 111 and the mounting post 110 and extends into the monitoring cylinder 104.

[0024] In this embodiment, the pH sensor 112 is model SEN0161. This device can monitor the pH value of water samples in the water supply network in real time, with a range of 0-14 pH, an accuracy of ±0.01 pH, and a response time of ≤5s. It can directly reflect the chemical stability of the water in the network.

[0025] The dissolved oxygen sensor 113DO-600 is a fluorescence-based dissolved oxygen sensor 113 with a range of 0-20 mg / L, an accuracy of ±0.05 mg / L, a response time of ≤8s, and no need for frequent calibration. It can stably monitor the dissolved oxygen content in the pipe network water.

[0026] The conductivity sensor 114 is an EC-400 type conductivity sensor with a range of 0-2000 μS / cm, an accuracy of ±1%FS, and a response time of ≤1s. It can indirectly reflect the content of dissolved solids (such as salts and minerals) in water by detecting the conductivity of the water sample.

[0027] Furthermore, the pH sensor 112, the dissolved oxygen sensor 113, and the conductivity sensor 114 are electrically connected to the main control module.

[0028] The pH sensor 112, the dissolved oxygen sensor 113, and the conductivity sensor 114 are respectively electrically connected to the main controller in the main control module, and the data collected by each sensor will be sent to the main controller for processing.

[0029] Furthermore, a sealing ring 109 is provided above the monitoring cylinder 104 to seal the gap between the mounting plate 111 and the monitoring cylinder 104.

[0030] In this embodiment, the sealing ring 109 is made of rubber. When the mounting post 110 and the threaded cylinder 108 are connected, the sealing ring 109 is squeezed between the threaded cylinder 108 and the mounting plate 111, and blocks the tiny gap between the threaded cylinder 108 and the mounting plate 111 to prevent water from overflowing.

[0031] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
