Description

Technical Field

[0001] The invention relates to the technical field of fluid metering instruments, in particular to a water meter counter detection device. Background Art

[0002] As global water resources become increasingly scarce, the rational and effective management and utilization of water resources has become the focus of attention of governments and scientific research institutions around the world. As a key tool for water resource measurement, the accuracy and reliability of water meters directly affect the effectiveness of water resource management. As an important device to ensure accurate water meter measurement, the technical development and application of water meter counter detection devices are of great significance to improving the efficiency of water resource management.

[0003] For example, the patent application with the prior art announcement number CN220853795U discloses a water meter counter detection device, which relates to the field of fluid metering instruments. The detection device has a simple structure and an ingenious design, and can be used to detect the quality of a water meter counter. The water meter counter detection device includes a detection platform for placing a water meter counter, a drive motor and a first sensor, the drive motor is used to sense and connect the central gear of the water meter counter placed on the detection platform, the first sensor is connected to the drive motor, and the first sensor is used to measure the rotational resistance of the drive motor.

[0004] The currently commonly used water meter counter detection technology mainly relies on setting up a drive motor to drive its center gear to rotate, and then detect the rotational resistance in this process. However, this method appears to be rather one-sided in practical applications, because it only focuses on the mechanical properties of the center gear, while ignoring other equally critical factors in the overall function of the water meter counter. In particular, the blades of the water meter counter are the core components of the water flow drive, and their precision and manufacturing process directly determine the metering accuracy and durability of the water meter. If the blades have design defects, manufacturing errors or wear, even if the rotational resistance test results of the center gear show normal, the water meter may still have problems such as inaccurate counting, missed counting or frequent failures during actual use. To this end, the present application proposes a water meter counter detection device. Summary of the invention

[0012] Preferably, one end of the pressure cylinder is fixedly connected to an exhaust pipe, and the other end of the double-headed piston rod extends into the interior thereof, the top of the exhaust pipe is connected to an air release pipe, one end of the air release pipe extends into the interior of the pillar, one side of the annular shell is rotatably connected to a crank, one end of the air release pipe is slidably connected to a driven piston rod adapted thereto, and the end of the driven piston rod away from the air release pipe is rotatably connected to the crank.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] By realizing the recycling of water flow, the waste of water resources is reduced, and the test process is also simplified. By directly comparing the readings of the test water meter with the benchmark water meter (calibrated standard water meter) under the same water flow conditions, the counting accuracy of the test water meter can be quickly and accurately evaluated. Through different valve combinations, the test mode can be easily switched. It can perform both conventional counting accuracy tests and performance evaluations under specific conditions, such as corrosion resistance and wear resistance tests in hard water environments. By performing multiple performance tests on the test water meter, potential problems in the design or manufacturing process can be discovered and corrected in a timely manner.

[0018] The central axis in the test water meter is directly driven to rotate by the drive assembly, simulating the actual movement of the central axis when water flows through the water meter.

The turbine is used to replace the blades inside the test water meter, and its counting position can be calculated under the same water volume, so as to accurately determine whether the blades in the test water meter are damaged. This method avoids the damage and inconvenience that may be caused by directly disassembling the water meter. When the test water meter and the reference water meter flow through the same water flow, if the counting index of the test water meter is inconsistent with that of the reference water meter, it means that the test water meter has defects. At this time, the same water flow is introduced by the drive assembly to drive the turbine to rotate, which can further determine whether the defect comes from the blade or the central axis. If the count of the test water meter is consistent with that of the reference water meter under the drive of the turbine, it means that the damage of the blade is the cause of the inaccurate counting; if it is still inconsistent, it means that the problem lies in the central axis. This step-by-step detection method greatly improves the efficiency and accuracy of troubleshooting. The design of the piston and tension spring enables the water flow to be introduced or blocked as needed, further enhancing the flexibility and controllability of the test.

[0019] Detectors such as industrial cameras can capture the state of the test water meter under dynamic changes, which helps to observe the performance of the water meter under different working conditions, such as counting accuracy, stability of pointer or digital display, etc. Through the cooperation of the pressure cylinder and the double-headed piston rod, the increase of water pressure inside the water meter is simulated, and whether there is water leakage is observed. At the same time, the water flow sprayed from the nozzle can simulate the influence of external water pressure on the surface of the water meter, detect its reading clarity and visibility, use water pressure to push the double-headed piston rod, and then drive the rotation of the crank and the ring shell through gas compression and the transmission of the driven piston rod, so as to realize the automation of the detection process. By simulating extreme working conditions such as water pressure increase and water leakage, potential problems that may exist in the water meter can be discovered in advance, such as poor sealing performance and material aging.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figure 1 , Figure 2 as well as Figure 3The present invention provides a technical solution: a water meter counter detection device, comprising a box body 100 with a built-in water tank, one side of the box body 100 is connected to a plurality of water inlet pipes 101, the other side of the box body 100 is provided with a plurality of through pipes 102, the top of the box body 100 is fixedly connected to a plurality of supports 104, and the plurality of supports 104 are used to support the through pipes 102 and the water inlet pipes 101, a test water meter 103 is fixedly connected between the plurality of water inlet pipes 101 and the plurality of through pipes 102, the test water meter 103 can be connected to the water inlet pipe 101 and the through pipe 102 through a meter clamp, the other ends of the plurality of through pipes 102 are fixedly connected to a benchmark water meter 105, the benchmark water meter 105 is a rectified standard, and its various indicators meet the requirements, and the other ends of the plurality of benchmark water meters 105 are connected to There is a return pipe 107 connected to the built-in water tank in the box body 100. The return pipe 107 can supply water back to the interior of the box body 100 to achieve recycling. The interiors of multiple water inlet pipes 101 are fixedly connected to water pumps 106. The water pump 106 can pump the water in the box body 100 into the interior of the test water meter 103. The top of the water inlet pipe 101 is fixedly connected to a pressure gauge 109. The pressure gauge 109 can measure the water pressure in the water inlet pipe 101, thereby detecting the water pressure strength that the test water meter 103 is borne by. The top of the box body 100 is fixedly connected to an auxiliary box 200. The auxiliary box 200 is used to store hard water. Detection components for detecting the test water meter 103 are arranged on both sides of the auxiliary box 200. By setting the detection components, the test water meter 103 can be effectively detected, and its multiple performances can be detected at the same time.

[0036] For further information, see Figure 4 , Figure 5 as well as Figure 6 The detection component includes an inlet pipe 201 connected to one side of the auxiliary box 200, the end of the inlet pipe 201 away from the auxiliary box 200 is connected to the through pipe 102, the other side of the auxiliary box 200 is connected to the return pipe 202, the side of the return pipe 202 away from the auxiliary box 200 is connected to the water inlet pipe 101, and the end of the through pipe 102 close to the test water meter 103 is fixedly connected to the fourth valve 205, the inside of the water inlet pipe 101 is fixedly connected to the fifth valve 206, the inside of the inlet pipe 201 is fixedly connected to the third valve 204, and the inside of the return pipe 202 is fixedly connected to the second valve 203. The cooperation between the third valve 204 and the second valve 203 can allow the water in the auxiliary box 200 to continuously pass through the test water meter 103 for detection, and the cooperation between the fifth valve 206 and the fourth valve 205 can allow water to flow through the test water meter 103 and the benchmark water meter 105, so as to facilitate the use of the test water meter 103 to detect the benchmark water meter 105 to test its quality.

[0037] Among them, closing the second valve 203 and the third valve 204 and opening the fifth valve 206 and the fourth valve 205 can achieve the continuity of water flow. The continuous water flow passes through the test water meter 103 and the benchmark water meter 105, so that the test water meter 103 and the benchmark water meter 105 are tested under the same water flow conditions, and the consistency of the test water meter 103 and the benchmark water meter 105 during the measurement process can be checked, which is helpful to discover potential measurement deviations or inconsistencies, so as to take corrective measures in time. Closing the fifth valve 206 and the fourth valve 205 and opening the second valve 203 and the third valve 204 will allow the hard water in the auxiliary box 200 to continuously pass through the test water meter 103, so that it can be subjected to a simulation test of a harsh environment.

[0038] Specifically, firstly, one end of the test water meter 103 is installed at one end of the through pipe 102, and the other end is installed at one end of the water inlet pipe 101. The second valve 203 and the third valve 204 can be closed, and the fifth valve 206, the fourth valve 205 and the first valve 108 can be opened. Then, the water pump 106 is turned on to pump the water in the box 100 into the inside of the water inlet pipe 101. At this time, the water flows through the test water meter 103, the through pipe 102, the reference water meter 105, and finally flows through the return pipe 107. Back to the inside of the box 100, the water flows through the test water meter 103 and the reference water meter 105, where the reference water meter 105 is the standard, and the counting accuracy of the test water meter 103 is detected by comparing with the reference water meter 105. The fourth valve 205 and the fifth valve 206 are closed, and the second valve 203 and the third valve 204 are opened. The water pump 106 is controlled to pump the hard water in the auxiliary box 200 into the inside of the test water meter 103 to perform a long-term continuous test to observe the operation of the water meter under different water quality conditions. This test can evaluate the corrosion resistance and wear resistance of the internal parts of the water meter.

[0039] In summary, by realizing the recycling of water flow, the waste of water resources is reduced, and the test process is also simplified. By directly comparing the readings of the test water meter with the calibrated standard water meter under the same water flow conditions, the counting accuracy of the test water meter can be quickly and accurately evaluated. Through different valve combinations, the test mode can be easily switched. It can perform both conventional counting accuracy tests and performance evaluations under specific conditions, such as corrosion resistance and wear resistance tests in hard water environments. By performing multiple performance tests on the test water meter, potential problems in the design or manufacturing process can be discovered and corrected in a timely manner.

[0040] Example 2: Please refer to Figure 7 , Figure 8 as well as Fig.11The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a water meter counter detection device, the top of the box 100 is provided with a driving component for driving the central axis of the test water meter 103 to rotate, and the central axis of the test water meter 103 can be directly driven to rotate by setting the driving component, so as to simulate its rotation under the same water volume, and the driving component includes a straight cylinder 302 connected to one end of the water inlet pipe 101, and the bottom of the straight cylinder 302 is connected to the side flow pipe 300, and the bottom of the test water meter 103 is provided with a connecting piece 307, and the bottom spline of the connecting piece 307 A coupling 301 is connected, and a casing 304 is rotatably connected to the outer surface of the coupling 301. The inside of the casing 304 is rotatably connected to a rotating shaft 305 fixedly connected to the coupling 301. A plurality of turbines 306 are fixedly connected to the outer surface of the rotating shaft 305. One side of the casing 304 is connected to a return pipe 303 connected to the casing 100. The side flow pipe 300 is connected to the casing 304. By setting the turbine 306, the blades inside the test water meter 103 can be replaced, and its counting position can be calculated under the same water volume, so as to know whether the blades in the test water meter 103 are damaged.

[0041] Furthermore, a piston 308 is slidably connected inside the straight cylinder 302 , a tension spring 309 is fixedly connected to one end of the straight cylinder 302 , and one end of the tension spring 309 is fixedly connected to the piston 308 .

[0042] Specifically, the fourth valve 205, the second valve 203 and the third valve 204 are closed, and the fifth valve 206 is opened. At this time, the water pump 106 is operated to pump the water in the box 100 into the water inlet pipe 101. At this time, the water pressure in the water inlet pipe 101 will gradually increase and push the piston 308 to slide inside the straight cylinder 302, so that the piston 308 passes over the side flow pipe 300 and the water supply flow passes through the side flow pipe 300 into the inside of the casing 304. At this time, the water flows through the casing 304 into the return pipe 303 and drives the rotating shaft 305 to rotate, thereby driving the coupling 301 to rotate and driving the central axis inside the test water meter 103 to rotate, thereby simulating the motor driving its central axis to rotate, and detecting whether its blades have defects.

[0043] It is worth mentioning that when the test water meter 103 and the benchmark water meter 105 flow through the same water flow, the counting index of the test water meter 103 is different from that of the benchmark water meter 105, which means that the test water meter 103 has a defect, and the defect may be caused by the damping of the central axis or the damage of the blades. At this time, the same water flow is introduced into the casing 304 to drive the turbine 306 to rotate. This turbine 306 is complete and qualified, and is used to replace the blades in the test water meter 103 to drive the central axis of the test water meter 103 to rotate. Subsequently, the count in the test water meter 103 is consistent with the count in the benchmark water meter 105, which means that the blades in the test water meter 103 are damaged, resulting in inaccurate counting of the test water meter 103. The count in the test water meter 103 is still inconsistent with the benchmark water meter 105, which means that the problem is not the blade problem but the damage to its central axis.

[0044] In summary, the central axis in the test water meter 103 is directly driven to rotate by the driving component, simulating the actual movement of the central axis when the water flows through the water meter. This simulation method can more accurately reflect the performance of the water meter under normal working conditions. The turbine 306 is used to replace the blades inside the test water meter 103, and its counting position can be calculated under the same water volume, so as to accurately determine whether the blades in the test water meter are damaged. This method avoids the damage and inconvenience that may be caused by directly disassembling the water meter. When the test water meter 103 and the reference water meter 105 flow through the same water flow, if the counting index of the test water meter is inconsistent with that of the reference water meter, it means that the test water meter has defects. At this time, the same water flow is introduced by the driving component to drive the turbine 306 to rotate, and it can be further determined whether the defect comes from the blade or the central axis. If the count of the test water meter is consistent with that of the reference water meter under the drive of the turbine 306, it means that the damage of the blade is the cause of the inaccurate counting; if it is still inconsistent, it means that the problem lies in the central axis. This step-by-step detection method greatly improves the efficiency and accuracy of troubleshooting. The design of the piston 308 and the tension spring 309 enables the water flow to be introduced or blocked as needed, further enhancing the flexibility and controllability of the test.

[0045] Example 3: Please refer to Fig. 9 , Fig.10 as well as Fig.12The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a water meter counter detection device, the top of the auxiliary box 200 is fixedly connected with a pillar 409, the inside of the pillar 409 is slidably connected with an annular shell 400, the bottom of the annular shell 400 is fixedly connected with a detector 410, the detector 410 can be an industrial camera, etc., which is used to shoot the dynamic changes of the test water meter 103 at a close distance, one side of the through pipe 102 is connected with a pressure cylinder 403, one end of the through pipe 102 close to the benchmark water meter 105 is fixedly connected with a first valve 108, one end of the pressure cylinder 403 is slidably connected with a double-headed piston rod 405, the top of the pressure cylinder 403 is connected with a water pipe 402, one end of the water pipe 402 away from the pressure cylinder 403 extends to the top of the annular shell 400 and is connected with it through a spring tube, the inner structure of the annular shell 400 is hollow, and the bottom thereof is provided with a plurality of nozzles 411 connected with the cavity, the inner part of the annular shell 400 is hollow and connected with a plurality of nozzles 411 to spray water to the surface of the test water meter 103.

[0046] For further information, see Fig.11 , Fig.12 as well as Fig.13 One end of the pressure cylinder 403 is fixedly connected to an exhaust pipe 404, and the other end of a double-headed piston rod 405 extends into the interior thereof, the top of the exhaust pipe 404 is connected to an air release pipe 401, one end of the air release pipe 401 extends into the interior of a support 409, one side of the annular shell 400 is rotatably connected to a crank 408, one end of the air release pipe 401 is slidably connected to a driven piston rod 407 adapted thereto, the end of the driven piston rod 407 away from the air release pipe 401 is rotatably connected to the crank 408, and the outer surface of the double-headed piston rod 405 is sleeved with a spring 406 for its own reset.

[0047] Specifically, by opening the fifth valve 206 and the fourth valve 205, and closing the second valve 203, the third valve 204 and the first valve 108, the water pump 106 is turned on to pump the water in the box 100 into the test water meter 103, and the water flows through the through pipe 102 and is blocked by the first valve 108. At this time, the water pressure in the through pipe 102 increases, which will push the piston at one end of the double-headed piston rod 405 to move toward the exhaust pipe 404. At this time, the gas in the exhaust pipe 404 is compressed and transported through the vent pipe 401 to push the activity of the driven piston rod 407. The plug end moves, thereby driving one end of the crank 408 to move and drive itself to tilt and pull the annular shell 400 to rotate in the support 409, thereby changing the positions of the multiple nozzles 411 and the detector 410. At the same time, the double-headed piston rod 405 moves to cross the water pipe 402, so that the water flow is transported to the inside of the annular shell 400 through the water pipe 402 and sprayed from the multiple nozzles 411 to the test water meter 103, so as to simulate the internal water pressure of the test water meter 103 to increase its water leakage condition. At the same time, the water flow is sprayed on its surface to detect its reading clarity and visibility.

[0048] In summary, the detector 410, such as an industrial camera, can capture the state of the test water meter 103 under dynamic changes, which is helpful to observe the performance of the water meter under different working conditions, such as counting accuracy, stability of the pointer or digital display, etc. Through the cooperation of the pressure cylinder 403 and the double-headed piston rod 405, the increase of water pressure inside the water meter is simulated, and whether there is water leakage is observed. At the same time, the water flow sprayed by the nozzle 411 can simulate the influence of external water pressure on the surface of the water meter, detect the clarity and visibility of its readings, use water pressure to push the double-headed piston rod 405, and then drive the rotation of the crank 408 and the ring shell 400 through gas compression and the transmission of the driven piston rod 407, so as to realize the automation of the detection process. By simulating extreme working conditions such as water pressure increase and water leakage, potential problems that may exist in the water meter can be discovered in advance, such as poor sealing performance and material aging.

[0049] Working principle: when in use, first install one end of the test water meter 103 at one end of the through pipe 102, and install the other end at one end of the water inlet pipe 101. The second valve 203 and the third valve 204 can be closed, and the fifth valve 206, the fourth valve 205 and the first valve 108 can be opened. Then, the water pump 106 is turned on to pump the water flow in the box 100 into the inside of the water inlet pipe 101. At this time, the water flows through the test water meter 103, through the through pipe 102, through the reference water meter 105, and finally flows through the return pipe 107 back to the inside of the box 100. At this time, the water flows through the test water meter 103 and the reference water meter 105, wherein the reference water meter 105 is the standard, and the counting accuracy of the test water meter 103 is detected by comparing with the reference water meter 105.

[0050] The fourth valve 205 and the fifth valve 206 can also be closed, the second valve 203 and the third valve 204 can be opened, and the water pump 106 can be operated to pump the hard water in the auxiliary tank 200 into the interior of the test water meter 103 to perform a long-term continuous test to observe the operation of the water meter under different water quality conditions. This test can evaluate the corrosion resistance and wear resistance of the internal parts of the water meter;

[0051] The fourth valve 205, the second valve 203 and the third valve 204 can also be closed, and the fifth valve 206 can be opened. At this time, the water pump 106 is operated to pump the water in the box 100 into the water inlet pipe 101. At this time, the water pressure in the water inlet pipe 101 will gradually increase, thereby pushing the piston 308 to slide inside the straight cylinder 302, so that the piston 308 passes over the side flow pipe 300 and the water flow enters the inside of the casing 304 through the side flow pipe 300. At this time, the water flows through the casing 304 into the inside of the return pipe 303 and drives the rotating shaft 305 to rotate, thereby driving the coupling 301 to rotate, thereby driving the central axis inside the test water meter 103 to rotate, and then simulating the motor driving its central axis to rotate, and detecting whether its blades have defects;

[0052] The fifth valve 206 and the fourth valve 205 can also be opened, while the second valve 203, the third valve 204 and the first valve 108 are closed. At this time, the water pump 106 is turned on to pump the water in the box 100 into the test water meter 103, and the water flows through the through pipe 102 and is blocked by the first valve 108. At this time, the water pressure in the through pipe 102 increases, which will push the piston at one end of the double-headed piston rod 405 to move toward the exhaust pipe 404. At this time, the gas in the exhaust pipe 404 is compressed and will be transported through the vent pipe 401 to push the piston end of the driven piston rod 407. The crank 408 moves, thereby driving one end of the crank 408 to move and drive itself to tilt and pull the annular shell 400 to rotate in the support 409, thereby changing the positions of the multiple nozzles 411 and the detector 410. At the same time, the double-headed piston rod 405 moves to pass over the water pipe 402, so that the water flow is transported to the inside of the annular shell 400 through the water pipe 402 and sprayed from the multiple nozzles 411 to the test water meter 103, so as to simulate the internal water pressure of the test water meter 103 to increase its water leakage condition. At the same time, the water flow is sprayed on its surface to detect the clarity and visibility of its readings.

[0053] In summary, by connecting the test water meter 103 and the reference water meter 105 in series and passing water at the same time, the counting accuracy of the two can be intuitively compared. The reference water meter 105 is used as a standard to accurately reflect the counting error of the test water meter 103, which is helpful to timely discover and correct potential counting problems. The specific valve is closed and the water pump 106 is turned on to pump the hard water or other specific water quality in the auxiliary box 200 into the test water meter 103 for long-term continuous testing. This test mode can simulate the working conditions of the water meter under long-term operation and different water quality conditions, evaluate the corrosion resistance and wear resistance of the internal parts of the water meter, ensure the stability and durability of the water meter in a complex environment, and detect whether there are defects in its blades by simulating the rotation of the central axis of the test water meter 103 driven by a motor. By controlling the valve and the water pump 106, the increase in water pressure inside the test water meter 103 is simulated, and whether there is water leakage is observed. At the same time, the water flow sprayed by the nozzle 411 simulates the influence of external water pressure on the surface of the water meter, and detects the clarity and visibility of its readings.
