This sophisticated design not only improves the device's adaptability in complex environments, but also significantly reduces maintenance costs and downtime, enhancing the device's overall performance. While operating efficiently.

[0044] Water quality sensor 42 is mounted on the end of detection tube 41.

[0045] A detection flow channel is formed between the first interface 412 , the accommodating cavity and the second interface 413 , which may be composed of one detection cylinder or multiple detection cylinders, depending on different design requirements.

[0046] In this application, a throttle valve 8 is provided at the outlet of the detection channel to control the water flow rate. Figure 11-12 A throttle flow channel is provided in the throttle valve 8, and a first retaining ring 81 and a second retaining ring 82 are provided on the inner wall of the throttle flow channel. The first retaining ring 81 and the second retaining ring 82 are coaxially arranged circular ring structures, which are rigidly arranged on the inner wall of the throttle valve 8. There is a gap between the first retaining ring 81 and the second retaining ring 82 to form an installation area 80; wherein, the first retaining ring 81 is located at the water inlet end, and a first hole body is provided at its center for water inlet, and the second retaining ring 82 is located at the water outlet end, and a second hole body is provided at its center for water outlet, and the aperture of the second hole body is smaller than that of the first hole body. At the same time, a working surface 82a facing the first retaining ring 81 is provided on the second retaining ring 82; a The elastic retaining ring 83 is made of rubber, is elastic and can produce elastic deformation. In this embodiment, the cross-section of the elastic retaining ring 83 is roughly circular, and a pressure surface is provided on one side of its water inlet end to increase the contact area with the water flow. A water hole is provided in the center of the elastic retaining ring 83. When the water flows through, it can impact the elastic retaining ring 83 and cause it to produce corresponding elastic deformation, resulting in extrusion, thereby changing the aperture of the water hole and realizing the adjustment of the water flow rate. The deformation amount depends on the flow rate. The greater the flow rate, the greater the deformation amount, and the smaller the flow rate, the smaller the deformation amount, thereby realizing autonomous flow regulation, so that there is always a stable water flow inside, thereby improving the detection accuracy.

[0047] In order to facilitate remote monitoring, a wireless communication module is also provided in the housing in this application for wireless signal transmission. The wireless communication module can not only transmit water quality data in real time, but also remotely control the solenoid valve according to the monitoring results.

[0048] In order to facilitate assembly, in this application, the cross-section of the shell 1 is a regular hexagon, and a fixed bracket 14 is fitted on its inner wall, and the detection component is installed on the fixed bracket 14. At the same time, in order to improve the internal cleanliness, a hub 5 is provided in the shell for connecting various water quality sensors, and the control module is arranged at the upper end of the shell.

[0049] To facilitate use in different locations, especially when there is no power supply, a battery is installed in the housing to provide power for detection. This makes the device easy to carry and move, adaptable to various environments, and highly practical. In addition, a non-slip pad is designed on the bottom of the housing to ensure stable operation of the device under various ground conditions and avoid errors caused by vibration.

[0050] At the same time, in order to facilitate assembly and improve structural strength, a horizontal partition is provided in the shell. The horizontal partition is arranged at the upper end of the shell and divides the installation cavity into an upper cavity and a lower cavity. The battery is arranged in the upper cavity and the detection component is arranged in the lower cavity. The structure is compact, the space occupied is small, and the structural strength is high.

[0051] The following is a brief description of its working principle:

[0052] The water sample to be tested enters from the manual valve, flows through the pressure reducing valve, and reaches the solenoid valve. This solenoid valve is normally closed and opens once every period of time. When the solenoid valve opens, the water sample to be tested enters the measurement module. The measurement module is equipped with a variety of water quality sensors, including but not limited to turbidity sensors, residual chlorine sensors, pH sensors, conductivity sensors, etc. An automatic throttle valve is installed at the outlet of the measurement module. When the water flow pressure is low, the inner hole of the elastic element inside the throttle valve increases, which can increase the cross-section of the water flow passing through. When the water flow pressure is high, the inner hole of the elastic element inside the throttle valve decreases, which reduces the cross-section of the water flow passing through, so that the entire measurement system has a stable water flow rate. The measured water sample will be discharged to the outside through a hose; the hub can uniformly transmit the data read by each sensor to the control module 7. The control module centrally processes the data and transmits it to the cloud platform through the antenna, while controlling each actuator.

[0053] The utility model discloses a multi-parameter water quality online monitoring device for a water supply network pipe, which has a compact structure, a small size, can realize external detection, and is flexible to install. It can be directly installed on an existing pipe network or placed on other platforms. It only needs to open one water inlet on the pipe network, which will not damage the pipe network. When not in use, the hole can be blocked or a valve or plug can be installed during installation. The utility model adopts a modular structure, which can be assembled and disassembled and upgraded according to different design requirements, and has high flexibility in use. The flexible pipe is adopted, which is convenient for placing the equipment at any position and docking with the water supply pipe, and has a wide range of applications. The throttle valve is provided to ensure the stability of the water flow and improve the detection precision and accuracy. The solenoid valve is provided to realize automatic opening, realize timed or interval detection, reduce manual intervention, and improve monitoring efficiency. The wireless communication module is provided to realize remote monitoring. The entire water quality detection module is installed vertically, which can effectively avoid the accumulation of bubbles in the water sample, eliminate the interference of bubbles on the detection, and improve the detection accuracy. The utility model discloses a multi-parameter water quality online monitoring device for a water supply network pipe, which has a compact structure, a small size, is convenient to install, has a wide range of applications, good use effect and high detection accuracy.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
