[0003] This water quality testing instrument is equipped with various types of sensors to detect various parameters in the water, such as pH, dissolved oxygen, turbidity, temperature, conductivity, etc. The sensor can collect data in real time and transmit it to the processing unit inside the meter. The water meter body is the core part of the entire water meter and is used to measure water flow. It is usually made of metal or plastic and has a certain degree of corrosion resistance and durability. The water meter body contains a turbine or ultrasonic sensor inside to measure water flow.

[0004] However, this water meter detection structure often uses a turbine to monitor the flow rate. Its basic principle is to use the effect of water flow on the turbine blades to drive the turbine to rotate, thereby measuring the water flow rate by changing the rotation speed or rotation angle. The runner of this turbine often adopts an integrated fixed structure, which may be damaged when subjected to long-term water flow impact. The single fixed structure makes the turbine of this water meter detection instrument difficult to maintain, and the entire internal turbine needs to be disassembled, which increases the difficulty of maintenance and reduces maintenance efficiency.

[0026] Specifically, through the water flow measuring tube 1 and the sensor 11, parameters such as water flow, water quality, pressure and temperature can be monitored. The sensor 11 is responsible for collecting these data in real time to ensure the stability of water quality and water flow. By cooperating with the Internet of Things, the water meter system has functions such as real-time monitoring, remote control and data transmission, and realizes remote monitoring and management. This intelligent solution provides convenience for water management, enabling managers to monitor and regulate the use of water resources more efficiently, thereby improving the efficiency and sustainability of water management. When the impeller inside the water flow measuring tube 1 is disassembled and maintained, the motor 3 outputs a rotating force to the rotating plate 4, driving the rotating plate 4 to rotate. While the rotating plate 4 rotates, the tilt angle is changed by rotating the multiple connecting rods 5 on its side wall. The rotation of the connecting rod 5 pulls the slide 7 to slide on the top of the slide rail 6. The sliding of the slide 7 can drive multiple connecting plates 8 to move inward to engage the impeller base. The impeller base is engaged in the groove inside the connecting plate 8. At the same time, the pulley 10 rotates inside the fixed platform 9, so that the impeller will not be affected in its rotation function after being fixed.

[0027] Reference Figure 3 The detection component includes a sensor 11, which is arranged on the top of the water flow measuring tube 1. The upper surface of the water flow measuring tube 1 is fixedly connected to a connecting tube 12, and the lower surface of the sensor 11 is fixedly connected to a connecting column 19. A chute 13 is provided inside the connecting tube 12, and a sliding bin 21 is fixedly connected to the side wall of the connecting tube 12. A chute 3 17 is provided inside the sliding bin 21, and a chute 2 14 is provided inside the sliding bin 21. A sliding column 15 is slidably connected inside the chute 2 14, and the outer wall of the sliding column 15 It is slidably connected inside the connecting column 19, one end of the spring 16 is fixedly connected to the side wall of the sliding column 15, one end of the spring 16 is fixedly connected to the inside of the sliding bin 21, the side wall of the connecting tube 12 is slidably connected to the card plate 18, the side wall of the card plate 18 is slidably connected to the inside of the sliding column 15, the side wall of the card plate 18 is rotatably connected to the inside of the slide groove 13, one end of the card plate 18 is slidably connected to the inside of the slide groove 3 17, a card groove 20 is opened inside the connecting column 19, and one end of the sliding column 15 is slidably connected to the inside of the card groove 20.

[0028] Specifically, first, by pressing the card plate 18 to rotate inside the chute 13, the rotation of the card plate 18 can make one end of the side wall of the card plate 18 slide inside the slide column 15, driving the slide column 15 to slide inside the chute 2 14 and the connecting pipe 12. The sliding process of the slide column 15 can be engaged and unlocked with the card slot 20 inside the connecting column 19. This step ensures the safe disassembly of the sensor 11, so that it can be easily removed from the water flow measurement tube 1. When the card plate 18 is released, the spring 16 will push the slide column 15 to keep it in a fixed state inside the card slot 20 to prevent the slide column 15 from accidentally falling off or moving. Such a design improves the maintenance efficiency of the water quality detection instrument, makes the replacement and maintenance of the sensor 11 more convenient and reliable, and ensures that the sensor 11 can continuously monitor parameters such as water flow, water quality, pressure and temperature, and collects water quality and water use data in real time for transmission with the Internet of Things. Through regular inspection and maintenance, the normal operation of the sensor 11 can be ensured, thereby ensuring the reliability and accuracy of the water quality monitoring system, providing important support for water resource management.

[0029] Working principle: When it is necessary to disassemble and maintain the impeller inside the water flow measuring tube 1, first start the motor 3. The motor 3 outputs a rotating force to the rotating plate 4 to drive the rotating plate 4 to rotate. While the rotating plate 4 rotates, it drives multiple connecting rods 5 on its side wall to rotate and change the inclination angle. The rotation of the connecting rod 5 then pulls the slide 7 to slide on the top of the slide rail 6. The sliding of the slide 7 can drive multiple connecting plates 8 to move toward the center to engage the impeller base. At the same time, the rotation of the pulley 10 inside the fixed platform 9 can ensure the normal rotation of the impeller. Through the efficient disassembly and assembly of the impeller, the long-term operation of the flow monitoring is guaranteed. At the same time, the water flow measuring tube 1 and the sensor 11 can monitor the water flow, water quality, pressure, temperature and other parameters and accurately measure the water flow through the water meter. Cooperating with the Internet of Things, it has the functions of real-time monitoring, remote control, data transmission, etc., providing a convenient and intelligent solution for water management. , since the sensor 11 is a transmission structure, it needs regular maintenance. When disassembling it, first press the card plate 18 to make it rotate inside the slide groove 13. The rotation of the card plate 18 makes the other side slide inside the slide column 15, and makes the slide column 15 slide inside the slide groove 14 and the connecting pipe 12. The sliding process of the slide column 15 can be engaged and unlocked with the card slot 20 inside the connecting column 19. The state of the connecting column 19 inside the connecting pipe 12 affects whether the connection state of the sensor 11 and the water flow measuring tube 1 is engaged. At the same time, the setting of the spring 16 can ensure that when the card plate 18 is released, the spring 16 pushes the slide column 15 to keep it in a fixed state inside the card slot 20 and it will not fall off easily, thereby improving the maintenance efficiency of the water quality detection instrument, facilitating the replacement and maintenance of the sensor 11, and ensuring that the sensor 11 monitors parameters such as water flow, water quality, pressure and temperature, and collects data on water quality and water use in real time.
