Description

Technical Field

[0001] The invention relates to the field of water supply measurement, and in particular to an intelligent water meter. Background Art

[0002] The water supply measurement field focuses on accurately measuring and monitoring the water flow of the water supply system through technical means to optimize water resource management and provide efficient and reliable water supply services. Smart water meters are indispensable tools in the field of water supply measurement. They are used to measure the amount of water consumed by users. They can help water supply companies to accurately bill and effectively monitor the use of water resources. The accuracy and reliability of water meters directly affect the management level and efficiency of the entire water supply system.

[0003] The Chinese patent with the publication number "CN211425563U" discloses "a water meter, comprising a base meter body, a base meter cover and an electric control body, the base meter body comprising a dial glass, a clamping locking cover arranged on the dial glass and a base meter housing threadedly connected to the clamping locking cover, the clamping locking cover comprising a clamping portion, the base meter cover is detachably connected to the base meter body through the clamping portion, the electric control body is fixedly connected to the base meter cover, and the electric control body cooperates with the base meter body to form a locking structure for limiting the rotation of the base meter cover";

[0004] In the above patent, "the metering base meter part is completely separated from the electronic control main body part, and maintenance and replacement are very convenient; the base meter cover is detachably fixed on the base meter body through the clamping part and the locking structure. When the water meter is repaired, the base meter cover will not be scrapped due to one-time dismantling of the meter for maintenance, which can reduce the maintenance cost of the water meter; a rotary clamping structure is adopted, and a clamping part and a locking structure are added. The assembly of the metering base meter is convenient and simple, and the positioning is accurate, and the water meter as a whole is easy to disassemble and assemble." However, it cannot prevent water backflow, so water backflow will occur, causing the precision metering components inside the base meter to be susceptible to backflow shock, which will not only affect the accuracy of the measurement and cause deviations in the water consumption data statistics, but also long-term and frequent backflow shocks may cause damage to the metering components, greatly shortening the service life of the water meter and increasing the frequency and cost of maintenance.

Detailed implementation manners

[0033] To make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0034] As Figure 1 - Figure 10 shown, an intelligent water meter includes a meter body 1, a dial 5 is arranged at the top of the meter body 1, a top cover 2 is rotatably connected to the top of the meter body 1, a water inlet connecting pipe 3 is fixedly connected through the rear part inside the meter body 1, a water outlet connecting pipe 4 is fixedly connected through the front and rear parts inside the meter body 1, and a check structure 6 is arranged inside the water outlet connecting pipe 4;

[0035] The non-return structure 6 includes two non-return plates 8. A molding block 7 is fixedly connected to the inside of the water outlet pipe 4. The two non-return plates 8 are arranged inside the molding block 7 and are symmetrical to each other. Two pairs of fixed blocks 10 are arranged inside the molding block 7 and at the top and bottom. A connecting block 9 is rotatably connected between each pair of fixed blocks 10. The connecting block 9 is fixedly connected to the non-return plate 8. The adjacent surfaces of the two non-return plates 8 are fixedly connected with sealing gaskets 11.

[0036] In actual operation, the water inlet pipe 3 is connected to the external water supply pipe, and the water outlet pipe 4 is connected to the external water pipe. Then, when the user uses water, the external water will enter the inside of the water inlet pipe 3 through the water supply pipe, and then flow through the inside of the meter body 1. The water consumption is calculated by the metering component inside the meter body 1, and the value is displayed on the dial 5.

[0037] Specifically, when water flows through the water outlet pipe 4, it will press against the two check plates 8, causing the two check plates 8 to rotate forward. At this time, the water can flow through the water outlet pipe 4 normally. When the water is about to flow back along the water outlet pipe 4, since the fixing block 10 and the connecting block 9 are located in front of the check plate 8, the check plate 8 can only rotate forward through the connecting block 9 and along the pair of fixing blocks 10, and cannot rotate backward. Therefore, when the water flows back along the water outlet pipe 4, it will be blocked by the two check plates 8, thereby preventing the water from flowing back to the meter body 1. Internally, therefore, under normal water use conditions, the check plate 8 can rotate flexibly to ensure that water flows smoothly through the water outlet pipe 4, does not affect normal water supply use, and maintains a stable water use experience; when unexpected water backflow occurs, such as in the initial stage of restoring water supply after water outage or when the water pressure is unstable, the check plate 8 blocks the water backflow, effectively protecting the precise metering components inside the meter body 1 from damage caused by the impact of water backflow, greatly extending the service life of the water meter, reducing maintenance costs and replacement frequency, and ensuring the stable operation of the water supply system.

[0038] In this embodiment, the interior of the molding block 7 is rectangular in shape, and the check plate 8 is adaptively matched with the interior of the molding block 7 .

[0039] In this embodiment, the connecting block 9 is located in front of the check plate 8, and a connecting shaft 12 is fixedly connected on both sides of the fixed block 10 and inside a pair of fixed blocks 10. A disc spring 13 is arranged inside the fixed block 10, one end of the disc spring 13 is fixedly connected to one end of the connecting shaft 12, and the other end of the disc spring 13 is fixedly connected to the inside of the fixed block 10.

[0040] When the check plate 8 rotates forward, it drives the connecting block 9 to rotate forward along a pair of fixed blocks 10 through the connecting shaft 12, thereby causing the connecting shaft 12 to rotate clockwise, thereby causing the disc spring 13 to contract. When the water supply stops, the check plate 8 is no longer pressed by the water flow, so the check plate 8 is no longer subjected to force, and the disc spring 13 rebounds, driving the check plate 8 to reset, thereby starting to perform a check operation on the water flow.

[0041] In this embodiment, the rear portions of the two check plates 8 are both provided with anti-water hammer structures 14, and the anti-water hammer structures 14 include ball seats 15, which are fixedly connected to the rear portions of the check plates 8, and the interior of the water outlet pipe 4 is fixedly connected to two support blocks 16, and a connecting tube 17 is fixedly connected through the two support blocks 16, and the interior of the ball seats 15 is connected to a rotating ball 20 through the rear portion, and a rotating rod 21 is fixedly connected to the outer surface of the rotating ball 20, and one end of the rotating rod 21 is rotatably connected to four rotating rods 22 rotatably connected to each other, and a piston 23 is fixedly connected to the outer surface of the rotating rod 22 at the rearmost and inside the connecting tube 17.

[0042] When the check plate 8 is pushed forward by the water flow, it will drive the ball seat 15 and the rotating ball 20 to rotate clockwise together, and then drive the rotating rod 1 21 to rotate forward, so that the four rotating rods 22 will not only rotate clockwise together, but also rotate with each other, and then drive the piston 23 to slide forward along the inside of the connecting tube 17. When the check plate 8 is reset due to the rebound of the disc spring 13, the piston 23 slides backward along the inside of the connecting tube 17 in the same way as above. Therefore, the piston 23 slides along the inside of the connecting tube 17, slowing down the reset speed of the check plate 8 due to the rebound of the disc spring 13, avoiding the water hammer effect caused by the rapid reset of the check plate 8. Therefore, the phenomenon of severe vibration of the water outlet pipe 4 due to the water hammer effect is avoided, thereby achieving the purpose of protecting the water outlet pipe 4 and the external water pipe connected thereto.

[0043] In this embodiment, the rear portion of the support block 16 is in a conical shape, and the rear portion of the connecting tube 17 is fixedly connected to a conical block 18 .

[0044] In this embodiment, a guide ring 19 is fixedly connected to the rear of the molding block 7, and the interior of the guide ring 19 is in a conical shape.

[0045] In this embodiment, a support structure 24 is provided at the front of the two check plates 8, and the support structure 24 includes an insert cylinder 26. Slots 25 are provided inside the molding block 7 near the top and the bottom. The insert cylinder 26 is fixedly connected to the front of the check plate 8. A rotating shaft 28 is rotatably connected to the front of the check plate 8 and located inside the insert cylinder 26. A guide groove 29 is provided on the outer surface of the rotating shaft 28. A guide block 30 is slidably connected inside the guide groove 29. An extrusion ring 32 is slidably connected between the inside of the insert cylinder 26 and the outer surface of the rotating shaft 28. The inner ring of the extrusion ring 32 is fixedly connected to the guide block 30. The rear part of the check plate 8 is located at the bottom of the ball seat 15 and is rotatably connected to a small turbine 27.

[0046] Specifically, the check plate 8 rotates forward due to the advancement of the water flow. When the check plate 8 rotates ninety degrees clockwise, the check plate 8 is in a horizontal state, and the water flow squeezes the top of the check plate 8. Since the cross-sectional area of ​​the top of the check plate 8 is small, the check plate 8 cannot continue to rotate clockwise at this time. Therefore, the maximum rotation angle of the check plate 8 is ninety degrees.

[0047] When the check plate 8 rotates clockwise to a horizontal state, at this time, the insert 26 will be inserted into the interior of the slot 25, and the small turbine 27 is in a horizontal state, and the flow of water will squeeze the blades of the small turbine 27, thereby driving the small turbine 27 to rotate, and then driving the rotating shaft 28 to rotate together, and through the guide groove 29, guide the guide block 30 to slide upward, thereby driving the extrusion ring 32 to slide upward, so that the extrusion ring 32 will squeeze the two blocks 31. Since the rear part of the block 31 is arranged in an inclined surface, the extrusion ring 32 will squeeze the two blocks 31, so that the two blocks 31 slide away from each other, and then the two blocks 31 enter the interior of the slot 25, so that the block 31 is engaged with the slot 25, and the small turbine 27 is continuously squeezed by the water flow, so that the block 31 is continuously engaged with the slot 25, thereby fixing the insert 26, and then driving the check plate 8 to be fixed, so that the check plate 8 will not be squeezed by the water flow when the water flows, resulting in a situation where it continues to shake.

[0048] Specifically, when the water supply is stopped, the water flow no longer flushes the small turbine 27, so that the small turbine 27 no longer rotates, and the extrusion ring 32 will slide down due to gravity, so that the extrusion ring 32 no longer squeezes the block 31, so the block 31 and the slot 25 are no longer engaged, so that the insert 26 and the check plate 8 are no longer fixed.

[0049] In this embodiment, two clamping blocks 31 are symmetrically slidably connected inside the inserting tube 26 , near one end thereof and penetrating the outer surface thereof. Both the clamping blocks 31 and the inserting tube 26 are adaptively matched with the slot 25 .

[0050] In this embodiment, the small turbine 27 is fixedly connected to the rotating shaft 28, and the rear portion of the clamping block 31 is arranged in an inclined surface.

[0051] In some embodiments, the smart water meter also includes a processor (not shown in the figure) and an ultrasonic sensor (not shown in the figure). The ultrasonic sensor is facing the check plate 8, and the processor is connected to the ultrasonic sensor signal. When water backflow occurs, the ultrasonic sensor continuously transmits multiple ultrasonic signals to the check plate 8, and receives multiple continuous ultrasonic data and sends them to the processor. The processor has a built-in trained generative adversarial network and a gated loop unit. The input of the generative adversarial network is multiple continuous ultrasonic data, and the output of the generative adversarial network is multiple check plate 8 working simulation images. The input of the gated loop unit is multiple check plate 8 working simulation images, and the output of the gated loop unit is that the check plate 8 is working normally or the check plate 8 is working abnormally. If the check plate 8 is working abnormally, the processor sends a check plate 8 working abnormality signal to the control port of the management user.
