Description

Technical Field

[0001] This invention relates to the field of smart water meter technology, specifically to a smart water meter with an anti-water hammer structure. Background Technology

[0002] The internal structure of a traditional water meter can be divided into three main parts from the outside in: the casing, the sleeve, and the inner core. The casing is made of cast iron. After water comes out from the inlet, it passes through the lower annular space of the casing, called the "lower annular chamber." Above this annular space is the "upper annular chamber," which connects to the outlet. The bottom of the sleeve has a filter screen with small holes to filter out impurities in the water. The side of the sleeve has two rows of circular holes, positioned opposite to the upper and lower annular chambers of the casing. Clearly, the lower row is the inlet, and the upper row is the outlet. It is particularly noteworthy that both rows of holes are angled along the tangent of the circle. The water flows in tangentially from the lower row of holes, inevitably creating a swirling water flow, which is crucial for the operation of the water meter. The inner core consists of three layers: upper, middle, and lower. Only the upper layer is visible through the glass window; only the finger... The needle and dial are important, but the most crucial part is the lower layer, which contains a plastic wheel with many plastic blades on its edge, called an "impeller." A smart water meter is a new type of water meter that uses modern microelectronics, modern sensing technology, and smart IC card technology to measure water consumption, transmit water data, and settle transactions. Compared to traditional water meters, which generally only have the functions of flow rate collection and mechanical pointer display of water consumption, this represents a significant improvement. Besides recording and electronically displaying water consumption, smart water meters can also control water consumption according to agreed-upon protocols. However, in pressurized pipelines, external factors such as sudden valve closure or sudden pump shutdown can cause a sudden change in water flow velocity, resulting in water hammer. This hydraulic phenomenon, known as water hammer, can easily damage the internal components of the water meter and requires preventative measures.

[0003] For example, patent document CN 113531177 B discloses a valve structure with stemless anti-water hammer effect, belonging to the field of valves. This stemless anti-water hammer valve structure includes a valve body and end caps fixed to both sides of the valve body. A valve core is located inside the valve body, and several rotating plates are evenly spaced at equal angles between the valve core and the inner wall of the valve body. The rotating plates have a fan-shaped structure, and a rotating shaft is fixed at the axis of the rotating plates. Bearing seats corresponding to the rotating shaft are provided on both the valve body and the valve core. An eccentric wheel is fixed at one end of the rotating shaft. A rubidium magnetic ring is slidably connected inside the valve body, and a pressure block corresponding to the eccentric wheel is provided on one side of the rubidium magnetic ring. An electromagnet matching the rubidium magnetic ring is fixed inside the valve body. Buffer ends are symmetrically provided on both sides of the valve core, and a guide post is fixed on one side of each buffer end. A sliding sleeve matching the guide post is provided on the valve core. This invention adopts a stemless structure design, has a long service life, effectively mitigates water hammer effect, provides strong protection, has market prospects, and is suitable for promotion.

[0004] However, in actual use, this structure can only protect against water hammer at the pipe valve. Therefore, it cannot reliably provide adequate water hammer protection for the impeller inside the water meter. Furthermore, because existing water meters typically use a straight-through connection design, the water entering the meter cannot flow in a curved path. This means that when water hammer occurs, the water inside the meter can generate significant water hammer force, causing severe impact on the impeller and easily damaging it. This necessitates timely maintenance, increasing the operating cost of the water meter and hindering daily use. Therefore, there is an urgent need to design a smart water meter with a water hammer-resistant structure to solve these problems. Summary of the Invention

[0005] The purpose of this invention is to provide a smart water meter with an anti-water hammer structure to solve the problem mentioned in the background art. In practical use, the existing structure can only prevent water hammer at the pipe valve, thus failing to provide stable and adequate anti-water hammer protection for the impeller inside the water meter. Furthermore, because existing water meters typically use a straight-through connection design, the water entering the meter cannot flow in a curved path. This leads to a significant water hammer force when water hammer occurs, causing severe impact on the impeller and easily damaging it. This necessitates timely maintenance, increasing the operating cost of the water meter and hindering daily use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a smart water meter with an anti-water hammer structure, comprising a connecting frame, a water meter body being provided at the right end of the surface of the connecting frame, a meter body frame being fixedly connected at the left end of the surface of the connecting frame, a meter body being provided on the surface of the meter body frame, a first side seat being fixedly connected at the left end of the bottom of the connecting frame, a second side seat being fixedly connected at the right end of the bottom of the connecting frame, a conveying seat being provided inside both the first and second side seats, a first fluid seat being fixedly connected at the bottom of the first side seat, a second fluid seat being fixedly connected at the bottom of the second side seat, a connecting rod being fixedly connected at the bottom of the conveying seat, a first rotating seat being provided at the bottom end of the connecting rod, rotating side frames being uniformly fixedly connected to the side of the first rotating seat, a biting frame being fixedly connected to one side of the rotating side frame, a shrinking seat being movably connected to the side of the biting frame, shrinking springs being provided inside the rotating side frame and the biting frame, and damping pads being provided on the inner walls of the rotating side frame and the biting frame;

[0007] A metering frame is provided, with its left and right ends fixedly connected to one end of a first side seat and a second side seat, respectively. A stabilizing frame is fixedly connected to the right side of the metering frame, and an adjusting frame is fixedly connected to the left side of the metering frame. A first control seat is fixedly connected to one end of the adjusting frame, and a water outlet frame is fixedly connected to one end of the first control seat. A second control seat is fixedly connected to the other end of the adjusting frame, and a water inlet frame is fixedly connected to one end of the second control seat. A fluid-connecting seat is fixedly connected to the bottom of the stabilizing frame, and a material injection valve seat is provided on one side of the fluid-connecting seat. Rotating rollers are provided at both ends of the inner wall of the stabilizing frame. A limiting band is movably connected to the inside of the stabilizing frame through the rotating rollers, and limiting strips are evenly fixedly connected to the sides of the limiting band.

[0008] Preferably, the bottom end of the rotating roller is provided with a second rotating seat, which has the same structure as the shrinking seat.

[0009] Preferably, the two ends of the control frame are fixedly connected to L-shaped support frames, one end of the L-shaped support frame is provided with a torque shaft, and one end of the L-shaped support frame is movably connected to an inclined rotating plate through the torque shaft.

[0010] Preferably, an adjusting spring is provided on the back of the tilting plate, and one end of the adjusting spring is fixedly connected to an adjusting seat.

[0011] Preferably, the inner wall of the first side seat is provided with a water inlet, and the inner wall of the second side seat is provided with a water outlet.

[0012] Preferably, the metering frame has an impeller body inside, and a first rotating shaft seat is provided at the top of the impeller body.

[0013] Preferably, rotating blades are uniformly fixedly connected to the side of the conveyor seat, and a second rotating shaft seat is fixedly connected to the top of the conveyor seat.

[0014] Preferably, an extension frame is fixedly connected to both sides of the bite frame, and the surface of the extension frame is provided with bite strips.

[0015] Preferably, the bottom ends of the first fluid seat and the second fluid seat are fixedly connected to a support seat, and one end of the water outlet frame and the water inlet frame is provided with a valve seat.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This smart water meter with an anti-water hammer structure, through its first side seat, second side seat, conveying seat, first fluid seat, second fluid seat, connecting rod, first rotating seat, rotating side frame, metering frame, stabilizing frame, connecting fluid seat, filling valve seat, rotating roller, limiting belt, and second rotating seat, provides more timely and stable anti-water hammer protection for the impeller body inside the metering frame. In actual use, the operator first connects the entire device to the water pipes at both ends of the outlet and inlet frames. The water flow rate inside the metering frame is then monitored daily through the meter body and the meter frame itself. The system efficiently records operations. When a sudden water outage occurs in the pipeline, the water inside the pipeline will stop abruptly, causing water hammer. At this time, the first and second side seats can quickly block the water flow at both ends of the metering frame, thus providing stable protection for the impeller body inside the metering frame. Normally, the conveying seats inside the first and second side seats rotate at a uniform speed under the impeller of the water flow through the rotating blades on the sides. At the same time, the first rotating seat connected to the bottom of the conveying seat by the connecting rod can rotate synchronously inside the first fluid seat and the second fluid seat respectively. At this time, the first fluid seat and the second fluid seat... Both the seat and the connecting fluid seat are filled with a pre-mixed and adapted non-Newtonian fluid. This non-Newtonian fluid has a relatively large hardening force, which matches the force generated during a water hammer. Normally, it does not affect the uniform rotation of the first rotating seat. At the moment a water hammer occurs, the first rotating seat, through its side rotating frame inside the first fluid seat, rapidly grasps the instantly hardened non-Newtonian fluid. This causes the contraction seat to contract within the rotating side frame and the biting frame via a contraction spring and damping pad. The biting frame, through its extension frames and biting strips on both sides, instantly grasps the hardened non-Newtonian fluid. At this moment, the first rotating seat... The moving seat restrains the rotating groove inside the first or second side seat of the conveying seat, thereby blocking the water flow at both ends of the conveying seat, reducing the force of water hammer. After the water hammer force disappears, the non-Newtonian fluid returns to a fluid state. At the same time, the rotating roller inside the stabilizing frame can also perform the same operation inside the fluid seat through the second rotating seat at the bottom. The limiting strip on the side of the limiting belt performs a stable emergency stop operation on the impeller body, which is normally limited. With stable cooperation, the instantaneous water hammer force is effectively blocked, thereby improving the service life of the impeller body and demonstrating the comprehensiveness of the equipment design.

[0018] This smart water meter with an anti-water hammer structure further improves the overall performance of the equipment through the arrangement of a first side seat, a second side seat, a control frame, a first control seat, a water outlet frame, an L-shaped support frame, a torque shaft, a tilting plate, an adjusting spring, an adjusting seat, an inlet, and a water outlet. During daily use, when water flows through both the water outlet and inlet frames, the control frame can adaptively adjust the water inlet and outlet through the L-shaped support frames at both ends, inside the first and second control seats respectively. When the water flows into the inlet frame, it contacts the tilting plate inside the second control seat. Driven by the water flow, the tilting plate rotates stably along the torque shaft of the L-shaped support frame, simultaneously coordinating with the adjusting spring and adjusting seat. The system employs adaptive reset and adjustment operations, performing adaptive regulation within the second control seat to ensure a more uniform water flow from the inlet into the first side seat. Similarly, when the water flows out of the outlet of the second side seat, adaptive control operations are also performed, resulting in more stable water flow within the first side seat, second side seat, and metering frame. This facilitates better subsequent water hammer protection. Furthermore, the water flow, after entering from the inlet, follows a centrifugal arc along the first side seat and also flows in an arc along the second side seat, preventing linear water hammer impact on the impeller within the metering frame. This further provides stable water hammer protection for the equipment components, demonstrating the comprehensiveness of the equipment design. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-8 One embodiment provided by the present invention:

[0030] A smart water meter with an anti-water hammer structure is disclosed in this application. The water meter body 2, meter body 4, contraction spring 15, damping pad 16, filling valve seat 25, torque shaft 31, adjusting spring 33, impeller body 37, first rotating shaft seat 38, and second rotating shaft seat 40 are commercially available products. Their principles and connection methods are existing technologies well-known to those skilled in the art. The meter includes a connecting frame 1, with the water meter body 2 mounted on the right end of the connecting frame 1, and the meter body frame 3 fixedly connected to the left end of the connecting frame 1. The meter body 4 is mounted on the surface of the meter body frame 3, and a first side seat is fixedly connected to the left end of the bottom of the connecting frame 1. 5. A second side seat 6 is fixedly connected to the right end of the bottom of the connecting frame 1. A conveying seat 7 is provided inside both the first side seat 5 and the second side seat 6. A first fluid seat 8 is fixedly connected to the bottom of the first side seat 5, and a second fluid seat 9 is fixedly connected to the bottom of the second side seat 6. A connecting rod 10 is fixedly connected to the bottom of the conveying seat 7. A first rotating seat 11 is provided at the bottom end of the connecting rod 10. Rotating side frames 12 are evenly fixedly connected to the side of the first rotating seat 11. A biting frame 13 is fixedly connected to one side of the rotating side frame 12. A shrinking seat 14 is movably connected to the side of the biting frame 13. A shrinking spring 15 is provided inside the rotating side frame 12 and the biting frame 13. The inner walls of the rotating side frame 12 and the biting frame 13 are provided with damping pads 16. The inner wall of the first side seat 5 is provided with a water inlet 35, and the inner wall of the second side seat 6 is provided with a water outlet 36. Rotating blades 39 are evenly fixedly connected to the side of the conveying seat 7. The top of the conveying seat 7 is fixedly connected with a second rotating shaft seat 40. The two sides of the biting frame 13 are fixedly connected with extension frames 41. The surface of the extension frames 41 is provided with biting strips 42. The bottom ends of the first fluid seat 8 and the second fluid seat 9 are fixedly connected with support seats 43. One end of the water outlet frame 21 and the water inlet frame 23 is provided with a valve seat 44. The first fluid seat 8, the second fluid seat 9 and the connecting fluid seat 24 are connected. The interior is filled with a well-mixed and adapted non-Newtonian fluid. This non-Newtonian fluid has a large hardening force, which matches the force generated during water hammer. Normally, it will not affect the uniform rotation of the first rotating seat 11. At the moment the water hammer occurs, the first rotating seat 11 quickly grasps the instantly hardened non-Newtonian fluid inside the first fluid seat 8 through the rotating side frame 12 on the side. This causes the contraction seat 14 to contract inside the rotating side frame 12 and the biting frame 13 through the contraction spring 15 and the damping pad 16. The contraction seat 14 then instantly grasps the hardened non-Newtonian fluid through the extension frame 41 and the biting strip 42 on both sides of the biting frame 13.

[0031] Metering frame 17 has its left and right ends fixedly connected to one end of the first side seat 5 and the second side seat 6, respectively. A stabilizing frame 18 is fixedly connected to the right side of the metering frame 17, and a regulating frame 19 is fixedly connected to the left side. One end of the regulating frame 19 is fixedly connected to a first control seat 20, and one end of the first control seat 20 is fixedly connected to a water outlet frame 21. The other end of the regulating frame 19 is fixedly connected to a second control seat 22, and one end of the second control seat 22 is fixedly connected to a water inlet frame 23. The stabilizing frame... A fluid-conducting seat 24 is fixedly connected to the bottom of the stabilizing frame 18. A material injection valve seat 25 is provided on one side of the fluid-conducting seat 24. Rotating rollers 26 are provided at both ends of the inner wall of the stabilizing frame 18. A limiting band 27 is movably connected to the inside of the stabilizing frame 18 through the rotating rollers 26. Limiting strips 28 are evenly fixedly connected to the side of the limiting band 27. A second rotating seat 29 is provided at the bottom end of the rotating rollers 26. The second rotating seat 29 has the same structure as the shrinkage seat 14. L-shaped support frames 30 are fixedly connected to both ends of the regulating frame 19. One end of the L-shaped support frame 30 is provided with a torque shaft 31. One end of the L-shaped support frame 30 is movably connected to an inclined rotating plate 32 via the torque shaft 31. An adjusting spring 33 is provided on the back of the inclined rotating plate 32. One end of the adjusting spring 33 is fixedly connected to an adjusting seat 34. An impeller body 37 is provided inside the metering frame 17. A first rotating shaft seat 38 is provided at the top of the impeller body 37. After the water flows into the water inlet frame 23, it can contact the inclined rotating plate 32 inside the second control seat 22. At this time, the water flow... Driven by the force, the tilting plate 32 can rotate stably along the torque shaft 31 of the L-shaped support frame 30. At the same time, it can perform adaptive reset adjustment in conjunction with the adjusting spring 33 and the adjusting seat 34. Adaptive control is performed inside the second control seat 22 to ensure that the water flow can enter the first side seat 5 more evenly from the inlet 35. Similarly, when the water flows out of the outlet frame 21 from the outlet 36 of the second side seat 6, adaptive control can also be performed.

[0032] Working Principle: During use, the operator first connects the entire device to the water pipes at both ends via the outlet frame 21 and the inlet frame 23. Normally, the water flow inside the meter frame 17 is efficiently recorded through the water meter body 2 and the meter body 4 inside the meter frame 3. When a sudden water outage occurs, the water inside the pipe will stop abruptly, causing water hammer. At this time, the first side seat 5 and the second side seat 6 can quickly block the water flow at both ends of the meter frame 17, thus providing stable protection for the impeller body 37 inside the meter frame 17. Normally, the conveyor seat 7 inside the first side seat 5 and the second side seat 6 rotates at a uniform speed under the push of the water flow through the rotating blades 39 on the sides. Simultaneously, the bottom of the conveyor seat 7 is connected by a connecting rod... The first rotating seat 11 connected to 10 can rotate synchronously inside the first fluid seat 8 and the second fluid seat 9. At this time, the interiors of the first fluid seat 8, the second fluid seat 9, and the connecting fluid seat 24 are all filled with a well-mixed and adapted non-Newtonian fluid. This non-Newtonian fluid has a large hardening force, which matches the force generated during water hammer. Normally, it will not affect the uniform rotation of the first rotating seat 11. At the moment of water hammer, the first rotating seat 11 quickly grasps the instantly hardened non-Newtonian fluid inside the first fluid seat 8 through the rotating side frame 12 on the side. This causes the contraction seat 14 to contract inside the rotating side frame 12 and the biting frame 13 through the contraction spring 15 and the damping pad 16. The contraction is then achieved through the extension frames 4 on both sides of the biting frame 13. 1. The gripping strip 42 performs an instantaneous gripping operation on the hardened non-Newtonian fluid. At this time, the first rotating seat 11 restrains the rotating groove inside the first side seat 5 or the second side seat 6 of the entire conveying seat 7, thereby blocking the water flow at both ends of the conveying seat 7, reducing the force of water hammer. After the water hammer force disappears, the non-Newtonian fluid returns to a fluid state. At the same time, the rotating roller 26 inside the stabilizing frame 18 can also perform the same operation inside the fluid seat 24 through the second rotating seat 29 at the bottom. The limiting strip 28 on the side of the limiting belt 27 performs a stable emergency stop operation on the impeller body 37, which is normally limited. With stable cooperation, the instantaneous water hammer force is effectively blocked, thereby improving the service life of the impeller body 37 in daily use. During the process, after water flows through both ends of the outlet frame 21 and the inlet frame 23, the control frame 19 can adaptively adjust the water inlet and outlet through the L-shaped support frames 30 at both ends, inside the first control seat 20 and the second control seat 22 respectively. When the water flows into the inlet frame 23, it can contact the inclined rotating plate 32 inside the second control seat 22. At this time, driven by the water flow, the inclined rotating plate 32 can rotate stably along the torque shaft 31 of the L-shaped support frame 30. At the same time, it cooperates with the adjusting spring 33 and the adjusting seat 34 to perform adaptive reset adjustment. Adaptive adjustment is performed inside the second control seat 22, thereby ensuring that the water flow can enter the first side seat 5 more evenly from the inlet 35.Similarly, when the water flows out of the outlet 36 of the second side seat 6 and exits the water rack 21, adaptive control operations can be performed to make the water flow inside the first side seat 5, the second side seat 6, and the metering rack 17 more stable, thus better supporting subsequent water hammer protection. Furthermore, the water flow, after entering from the inlet 35, can perform a centrifugal arc-shaped flow along the first side seat 5, and also flows in an arc-shaped manner when entering the second side seat 6. This prevents the impeller body 37 inside the metering rack 17 from experiencing straight-line water hammer impact, thereby further providing stable water hammer protection for the equipment components. The above describes the entire working principle of this invention.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
