Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline network testing, specifically to a multi-parameter measuring device for pipeline networks. Background Technology
[0002] In today's urban construction and industrial production, the efficient operation of pipeline systems plays a crucial role in ensuring people's daily lives and production activities. Whether it's urban water supply and drainage networks or various liquid transport networks in industrial production, accurate monitoring of their internal parameters is essential. With technological advancements, there is a desire to acquire comprehensive information on pressure, flow rate, temperature, and water quality within the pipeline network simultaneously using a multi-parameter measuring device, thereby achieving complete control and refined management of the pipeline system. However, significant challenges exist in the actual water quality measurement process.
[0003] The water inside the pipeline network is not in a pure, ideal state; its composition is complex and diverse. It may contain solid particles such as silt and rust. These particles, carried by the water flow, easily collide with and adhere to the surface of the sensor components, gradually accumulating to form a layer of dirt, affecting the sensor's sensitivity and measurement accuracy. Simultaneously, the water also contains a large number of microorganisms. Under suitable temperature and nutrient conditions, these microorganisms can multiply rapidly on the sensor, forming a biofilm. This biofilm hinders normal contact between the sensor and the water, interfering with the sensor's detection of substances in the water and leading to deviations in the measurement data.
[0004] Therefore, a multi-parameter measurement device for pipeline networks is proposed. Utility Model Content
[0005] In view of the problems existing in the above-mentioned multi-parameter measurement devices for pipeline networks, this utility model is proposed.
[0006] Therefore, the purpose of this utility model is to provide a multi-parameter measuring device for pipeline networks, which solves the problems raised in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A multi-parameter measuring device for pipelines includes an arc-shaped fixing clamp, a housing, a data processing module, a data transmission module, a measuring tube, and a sensor assembly. The housing is fixedly mounted on the top of the arc-shaped fixing clamp, and a fixing mechanism is provided at the bottom of the arc-shaped fixing clamp. One end of the measuring tube is fixedly connected to the bottom of the housing, and the other end of the measuring tube extends into the interior of the arc-shaped fixing clamp. The sensor assembly is fixedly embedded in the wall of the measuring tube. The data processing module and the data transmission module are both fixedly installed inside the housing. A motor is fixedly mounted on the bottom inner wall of the housing, and a rotating shaft is fixedly mounted on the output end of the motor. The rotating shaft passes through the interior of the measuring tube, and a connecting rod is fixedly mounted on the lower end of the rotating shaft. A cleaning brush is fitted against the wall of the measuring tube, and a cleaning plate is fixedly mounted on one side of the cleaning brush. The lower end of the cleaning plate is fixedly connected to one end of the connecting rod.
[0009] Preferably, the fixing mechanism includes two fixing rings, a fixing bolt, and a fixing nut. The two fixing rings are respectively fixedly disposed at the bottom ends of the arc-shaped fixing clamp, and the two fixing rings are fixedly connected by the fixing bolt and the fixing nut.
[0010] Preferably, a sealing rubber gasket is fixedly provided on the inner side wall of the arc-shaped fixing clamp.
[0011] Preferably, the cleaning brush is made of nylon bristles.
[0012] Furthermore, both ends of the measuring tube are enclosed structures, and both ends of the measuring tube are fixedly embedded with sealed bearings that are rotatably connected to the rotating shaft.
[0013] Preferably, the measuring tube has a metal shielding mesh inside its sidewall, and the metal shielding mesh is composed of annular wires and straight wires.
[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0015] 1. Effective anti-fouling and descaling ensures measurement accuracy: The motor drives the rotating shaft, which in turn moves the connecting rod and cleaning plate. The cleaning brush then wipes the surface of the sensor assembly, effectively removing the scale layer formed by solid particles such as silt and rust in the water. This ensures that the sensor maintains high sensitivity and measurement accuracy at all times, avoiding measurement data deviations caused by scale buildup. This greatly improves the accuracy and reliability of the device in long-term measurements under complex water quality environments. At the same time, the regular mechanical cleaning action ensures that the sensor assembly maintains good contact with the water, preventing interference from biofilms in the measurement process. This guarantees the stability of the sensor's detection of substances in the water, ensuring that the acquired water quality parameters are true and valid, and providing stable data support for the refined management of the pipeline network system.
[0016] 2. Enhanced anti-interference capability with metal shielding: The metal shielding mesh inside the side wall of the measuring tube is composed of ring wires and straight wires. The sensor group's wiring passes through the inside of the measuring tube, which can effectively shield external electromagnetic interference, ensure the accuracy of measurement data and the stability of transmission, and enable the device to work stably in various environments, thus enhancing the applicability and reliability of the device.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0024] This utility model provides, for example Figure 1-2The illustrated multi-parameter measuring device for a pipeline network includes an arc-shaped fixing clamp 1, a housing 2, a data processing module 3, a data transmission module 4, a measuring tube 5, and a sensor assembly 6. The housing 2 is fixedly mounted on the top of the arc-shaped fixing clamp 1, and a fixing mechanism is provided at the bottom of the arc-shaped fixing clamp 1. One end of the measuring tube 5 is fixedly connected to the bottom of the housing 2, and the other end of the measuring tube 5 extends into the interior of the arc-shaped fixing clamp 1. The sensor assembly 6 is fixedly embedded in the wall of the measuring tube 5. The data processing module 3 and the data transmission module 4 are both fixedly installed inside the housing 2. A motor 7 is fixedly mounted on the inner bottom wall of the housing 2, and a rotating shaft 8 is fixedly mounted on the output end of the motor 7. The rotating shaft 8 passes through the interior of the measuring tube 5, and a connecting rod 9 is fixedly mounted on the lower end of the rotating shaft 8. A cleaning brush 10 is attached to the wall of the measuring tube 5. The cleaning brush 10 is made of nylon bristles, which have good wear resistance. When cleaning the surface of sensor assembly 6, even with frequent friction against solid particles such as mud, sand, and rust, it is not easily worn or broken, maintaining a long-term cleaning effect and effectively reducing the frequency of brush replacement, thus ensuring the continuous and stable operation of the device. Secondly, the nylon bristles have a certain degree of flexibility, generating sufficient friction to remove dirt and microorganisms when in contact with the surface of sensor assembly 6, without causing scratch damage to sensor assembly 6, ensuring the integrity and measurement accuracy of sensor assembly 6. In addition, nylon material has stable chemical properties and is not easily corroded or chemically reacted by chemicals in the water in complex water quality environments, thus maintaining its own physical and cleaning performance and adapting to long-term use under different water quality conditions. Furthermore, a cleaning plate 11 is fixedly provided on one side of the cleaning brush 10, and the lower end of the cleaning plate 11 is fixedly connected to one end of the connecting rod 9.
[0025] like Figure 1 The fixing mechanism includes two fixing rings 12, fixing bolts 13, and fixing nuts 14. The two fixing rings 12 are respectively fixed at the bottom ends of the arc-shaped fixing clamp 1, and the two fixing rings 12 are fixedly connected by the fixing bolts 13 and fixing nuts 14. A sealing rubber gasket 15 is fixedly provided on the inner side wall of the arc-shaped fixing clamp 1. During installation, the arc-shaped fixing clamp 1 is wrapped around the outer wall of the pipe so that the sealing rubber gasket 15 fits against the outer wall of the pipe. Then, the arc-shaped fixing clamp 1 is fixed to the pipe by tightening the fixing bolts 13 and fixing nuts 14.
[0026] like Figure 2-3 Both ends of the measuring tube 5 are closed structures, and both ends of the measuring tube 5 are fixedly embedded with sealed bearings that are rotatably connected to the rotating shaft 8, thereby increasing the rotational sealing between the rotating shaft 8 and the measuring tube 5. A metal shielding mesh 16 is provided inside the side wall of the measuring tube 5, and the metal shielding mesh 16 is composed of annular wires and straight wires. The circuit of the sensor group 6 passes through the inside of the measuring tube, which can effectively shield external electromagnetic interference and ensure the accuracy of the measurement data and the stability of the transmission.
[0027] Working principle: During pipeline installation, the device is fixed to the pipeline using the fixing mechanism (two fixing rings 12, fixing bolts 13 and fixing nuts 14) at the bottom of the arc-shaped fixing clamp 1. The sealing rubber gasket 15 on the inner side of the arc-shaped fixing clamp 1 ensures tight installation and prevents water leakage. At the same time, it allows the measuring tube 5 to be inserted into the pipeline. When the device is working, the sensor group 6 monitors parameters such as pressure, flow, temperature and water quality in the pipeline in real time and transmits the data to the data processing module 3. After the data processing module 3 analyzes and processes the data, it sends the results out through the data transmission module 4. When the sensor group 6 needs to be cleaned, the motor 7 is started. The motor 7 drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the connecting rod 9 and the cleaning plate 11 to move. The cleaning brush 10 slides on the wall of the measuring tube 5 to clean the surface of the sensor group 6, removing dirt and microorganisms, which greatly improves the accuracy and reliability of the device in long-term measurement under complex water quality environments.
