[0002] Water quality testing is the process of testing and analyzing the physical, chemical and biological indicators in water bodies to assess the safety and suitability of water. These tests usually include the determination of pollutants, harmful substances, nutrients and microorganisms in the water. Drinking water quality testing can ensure that the water people drink is non-toxic and harmless, meets hygiene standards, and prevents various diseases caused by water quality problems. The usual practice for water quality testing is to use contact testing. After sampling the sample, the detection sensor is directly in contact with the water sample to detect the water quality of the water sample.

[0023] In this embodiment, when in use, the smart water meter 102, the forward and reverse motor 201, the electromagnet 208, the servo motor 302 and the PLC controller 106 are electrically connected, and a plurality of L-shaped rods 317 are installed on both sides of the detection sleeve 103. The L-shaped rods 317 distributed circumferentially on the same horizontal plane form a group, and there are two groups in total, which are installed on both sides of the detection sleeve 103 respectively. Three support rings 307 are arranged inside the detection sleeve 103, and the arc block 312 is located in the arc hole 309 on the left side. Figure 3As shown, the acoustic wave sensor 315 is started, and in the process of detecting the quality and flow of water through the water quality and water quantity detection component 1, the servo motor 302 is started, and the output end of the servo motor 302 drives the driving wheel 303 to rotate, and then drives the meshing driven wheel 304 to rotate, and drives the convex rod 305 to rotate, and at the same time drives the rotating wheel 306 to rotate on the outer surface of the L-shaped rod 317. When the convex rod 305 rotates, it drives the connecting block 311 and the arc block 312 to rotate together, so that the arc block 312 slides into the annular groove 308. The connecting block 311 is located on the outer surface of one side of the support ring 307. The connecting block 311 1 does not contact with the support ring 307, the driven wheel 304 drives the convex rod 305 to rotate around the outer surface of the detection tube 101, so that the arc block 312 rotates inside the annular groove 308. With the cooperation of the support ring 307 and the arc block 312, it is beneficial to improve the stability of the rotation of the connecting block 311. When the connecting block 311 rotates, it will drive the detection plate 314 and the internal acoustic wave sensor 315 to rotate along the outer surface of the detection tube 101, so that the acoustic wave sensor 315 can detect the water in the tube from different circumferential angles, overcoming the limitation that the fixed position detection can only be observed from a single angle. The distribution of substances in the water and possible unevenness can be more fully understood, and the reliability of the detection results can be improved. Through comprehensive analysis of detection data from multiple angles, measurement errors can be reduced, the accuracy of detection can be improved, and the accumulation of pollutants in a specific area can be avoided, which affects the accuracy of water quality detection. When the connecting block 311 and the arc block 312 rotate along the outer surface of the detection tube 101 for a circle, they will return to the arc hole 309 again. At this time, the servo motor 302 will automatically pause for a period of time, and the electromagnet 208 will be powered on and started. The magnetism of the electromagnet 208 is the same as that of the magnet 210, and repulsive magnetism will be generated between the electromagnet 208 and the magnet 210. Under the action of the repulsive force, the moving plate 209 is pushed downward, so that the reset spring 212 is squeezed and contracted, and the two plug rods 213 are pushed through the two moving holes 214 into the two card slots 316, thereby moving the slider 20 6 is connected with the connecting block 311, and then the forward and reverse motor 201 is started, and the rotation of the output end of the forward and reverse motor 201 drives the first transmission roller 202 to rotate, and then drives the transmission belt 203 and the second transmission roller 204 to rotate, and drives the slider 206 to move to the right on the outer surface of the support plate 205, and further drives the connecting block 311 to move to the right on the outer surface of the protruding rod 305. When the arc block 312 moves to the arc hole 309 in the middle, the forward and reverse motor 201 automatically pauses for a period of time. At this time, the electromagnet 208 is powered off, the repulsive force disappears, the reset spring 212 loses pressure, starts to rebound, pushes the moving plate 209 to move upward, and pulls the two plug rods 213 away from the card slot 316, so that the connection block 311 and the slider 206 lose connection, and then the servo motor 302 resumes work, and continues to drive the driving wheel 303, the driven wheel 304 and the protruding rod 305 to rotate.At this time, the arc block 312 slides into the annular groove 308 of the middle support ring 307, thereby driving the acoustic wave sensor 315 to rotate in a circle at the middle position of the detection tube 101, and performing multi-angle water quality detection on the middle position of the detection tube 101. After completing the water quality detection at the middle position, the servo motor 302 pauses for a period of time again, and repeats the above operation process, so that the connecting block 311 and the acoustic wave sensor 315 move to the right support ring 307, and perform multi-angle water quality detection on the right side of the detection tube 101. Finally, the output end of the forward and reverse motor 201 rotates in the opposite direction, driving the slider 206, the connecting block 311 and the acoustic wave sensor 315 to move in the opposite direction and return to the left position for the next round of water quality detection. Under the action of the moving component 2, it can be achieved The lateral movement of the acoustic wave sensor 315 allows the acoustic wave sensor 315 to perform detection at different horizontal positions of the detection tube 101, avoiding the local deviation that may occur in the detection of a single position, ensuring a more comprehensive understanding of the water quality in the length direction of the detection tube 101. With the cooperation of the moving component 2 and the rotating component 3, the effect of water quality detection in the horizontal direction and at multiple angles can be achieved, avoiding the accumulation of dirt in a certain place and affecting the detection result. This solves the problem that when a non-contact water quality detection water meter detects water quality, the detection sensor is generally fixedly installed in a certain position and can only obtain detection data in a specific area. When pollutants accumulate in a specific area, it is easy to cause deviations in the water quality detection results, reducing the accuracy of the water quality detection results.

[0024] Embodiment 2: Figure 1-Figure 4 and Figure 8 As shown, it includes a water quality and quantity detection component 1, which is used to detect water quality and water quantity. A moving component 2 and a rotating component 3 are arranged inside the water quality and quantity detection component 1. The moving component 2 is used to drive the detection sensor to move horizontally, and the rotating component 3 is used to drive the detection sensor to rotate in a circle; the water quality and quantity detection component 1 includes a detection tube 101, one end of the detection tube 101 is threadedly sleeved with a smart water meter 102, the outer surface of the detection tube 101 is movably sleeved with a detection sleeve 103, and the outer surface of the detection sleeve 103 A movable hole 108 is opened on the surface, and a mounting cover 104 is installed on the outer surface of the detection sleeve 103 near the movable hole 108 by bolts, a Bluetooth module 107 is installed on the rear wall inside the mounting cover 104 by bolts, a PLC controller 106 is installed on the rear wall inside the mounting cover 104 near the Bluetooth module 107 by screws, a communication module 105 is installed on the rear wall inside the mounting cover 104 near the PLC controller 106 by screws, and the detection sleeve 103 is connected to the detection tube 101 by bolts.

[0025] In this embodiment, when in use, the acoustic wave sensor 315 is connected to the PLC controller 106 via Bluetooth through the Bluetooth module 107, and the PLC controller 106 is wirelessly connected to the external control platform through the communication module 105. The other end of the detection tube 101 is threadedly connected to the external water supply equipment, and the water to be tested is transported to the detection tube 101, and the acoustic wave sensor 315 is driven to move and rotate by the moving component 2 to perform water quality testing on the water in the detection tube 101. The acoustic wave sensor 315 emits sound waves, so that the sound waves are transmitted to the detection tube 101 through the square hole at the bottom of the detection plate 314, and then transmitted to the water flow in the tube through the wall of the detection tube 101, and then returned to the acoustic wave sensor 315. The rate at which sound waves propagate in water is related to the physical and chemical properties of water. Changes in water quality will cause changes in the propagation speed and attenuation characteristics of sound waves. The reflected sound wave signal received by the sound wave sensor 315 is analyzed through a signal processing algorithm to extract information to determine the quality parameters of the water, thereby detecting the water quality. The information is then transmitted to the PLC controller 106 via Bluetooth for data processing and data storage to achieve non-contact water quality detection. After the water quality detection, the water enters the smart water meter 102. The smart water meter 102 can detect the water flow and transmit the detected water volume data to the PLC controller 106 in the form of an electrical signal for identification and comparison. In the next step, the water quality and water volume data are uploaded to the external control platform through wireless transmission, which is convenient for staff to detect the water quality and water volume in real time and achieve comprehensive monitoring. It can provide more comprehensive data, help to fully understand the use and quality of water, discover problems in time, and take measures.

[0026] The effect and working principle of the whole mechanism are as follows: the PLC controller 106 is wirelessly connected to the external control platform through the communication module 105, the other end of the detection tube 101 is threadedly connected to the external water supply equipment, the water to be detected is transported to the detection tube 101, the acoustic wave sensor 315 is started to detect the water quality of the water in the detection tube 101, and the data is transmitted to the PLC controller 106 via Bluetooth for data processing and data storage, so as to realize non-contact water quality detection, and then the water enters the smart water meter 102, the smart water meter 102 can detect the water flow, and transmit the detected water volume data to the PLC controller 106 in the form of electrical signals for identification and comparison, and the water quality and water volume data are transmitted wirelessly in the next step. Upload to the external control platform to facilitate the staff to detect the water quality and water quantity in real time, realize comprehensive monitoring, and provide more comprehensive data. Start the servo motor 302 to drive the active wheel 303 and the driven wheel 304 to rotate, and drive the convex rod 305 to rotate, and at the same time drive the rotating wheel 306 to rotate on the outer surface of the L-shaped rod 317. When the convex rod 305 rotates, it drives the connecting block 311 and the arc block 312 to rotate together, so that the arc block 312 slides into the annular groove 308. The driven wheel 304 drives the convex rod 305 to rotate around the outer surface of the detection tube 101, and drives the connecting block 311 to rotate, so that the acoustic wave sensor 315 rotates along the outer surface of the detection tube 101, and detects the water in the tube from different circumferential angles. When the connecting block 31 After the arc block 312 rotates along the outer surface of the detection tube 101 for one circle, it returns to the arc hole 309 again. At this time, the servo motor 302 will automatically pause for a period of time, and the electromagnet 208 is powered on and started. The magnetism of the electromagnet 208 is the same as that of the magnet 210. Repulsive magnetism will be generated between the electromagnet 208 and the magnet 210. Under the action of the repulsive force, the moving plate 209 is pushed to move downward, so that the reset spring 212 is squeezed and contracted, and the two insertion rods 213 are pushed through the two moving holes 214 into the two card slots 316, so that the slider 206 is connected with the connecting block 311. Then the forward and reverse motors 201 are started, driving the first transmission roller 202, the transmission belt 203 and the second transmission roller 204 to rotate, and driving The slider 206 moves to the right on the outer surface of the support plate 205, further driving the connecting block 311 to move to the right on the outer surface of the protruding rod 305. When the arc block 312 moves to the arc hole 309 in the middle, the forward and reverse motors 201 automatically pause for a period of time. At this time, the electromagnet 208 is powered off, the repulsive force disappears, the reset spring 212 loses pressure, and begins to rebound, pushing the moving plate 209 to move upward, and pulling the two plug rods 213 out of the slot 316, so that the connection between the connecting block 311 and the slider 206 is lost. Then the servo motor 302 resumes working and continues to drive the driving wheel 303, the driven wheel 304 and the protruding rod 305 to rotate. At this time, the arc block 312 slides into the annular groove 308 of the middle support ring 307.Thereby, the acoustic wave sensor 315 is driven to rotate in a circle at the middle position of the detection tube 101, and the water quality detection at the middle position of the detection tube 101 is performed at multiple angles. After the water quality detection at the middle position is completed, the servo motor 302 is paused for a period of time again, and the above operation process is repeated, so that the connecting block 311 and the acoustic wave sensor 315 are moved to the right support ring 307, and the water quality detection at the right position of the detection tube 101 is performed at multiple angles. Finally, the output end of the forward and reverse motor 201 rotates in the opposite direction, driving the slider 206, the connecting block 311 and the acoustic wave sensor 315 to move in the opposite direction, return to the left position, and perform the next round of water quality detection. Under the action of the moving component 2, the acoustic wave sensor 315 can be moved horizontally, so that the acoustic wave sensor 315 can be detected at different horizontal positions of the detection tube 101. Under the cooperation of the moving component 2 and the rotating component 3, the effect of water quality detection in the horizontal direction and at multiple angles can be achieved, and the accumulation of dirt in a certain place can be avoided to affect the detection result.
