Description

Technical Field

[0001] This invention belongs to the field of water meter technology, and particularly relates to a water meter and its manufacturing system and method. Background Technology

[0002] A water meter is an instrument used to measure water flow, mostly for measuring cumulative water flow. Currently, most residential water meters use water to drive an impeller to measure the cumulative amount of water used, i.e., rotary vane water meters. Water meters can be divided into volumetric and rotary vane types. Volumetric meters measure the amount of water used, while rotary vane meters measure indirectly based on the speed of the water flow and the rotation speed of the impeller. However, in actual use, the quality of the water flowing through the water meter cannot be guaranteed, so impurities in the water can easily enter the water meter. Over time, this can cause excessive impurities to adhere to the rotor, affecting the measurement results and thus the lifespan of the water meter. To overcome this, existing technologies incorporate a filter inside the water meter to filter the water flowing through it and extend its lifespan. However, current technologies cannot efficiently and automatically detect the filtration effect of the filter in water meters with filters during the manufacturing process, requiring manual detection, which is inefficient and wastes human resources. Summary of the Invention

[0003] In view of this, the technical problem to be solved by the present invention is to provide a water meter and its manufacturing system and method, which can efficiently and automatically detect the filtration effect of the filter in the water meter with filter.

[0004] A water meter manufacturing system includes a fixed frame and a vertical rod. Two fixed clamps are slidably connected to the fixed frame. A moving head is slidably connected to the vertical rod. A tension spring is fixed between the vertical rod and the moving head. A scale is provided on the vertical rod. A detection part is rotatably connected to the moving head. A filter plate is slidably connected to the detection part. A toggle rod is connected to the vertical rod. The toggle rod can move up and down on the vertical rod. A displacement sensor is fixed to the vertical rod. The moving end of the displacement sensor is fixed to the moving head. Multiple through holes are provided on the filter plate.

[0005] It also includes two fixing rods fixed to the fixing frame, with the two fixing rods located directly above the two fixing clamps.

[0006] It also includes an arc-shaped brush fixed to the detection unit.

[0007] It also includes a horizontal bar fixed to the vertical bar, a horizontal block slidably connected to the horizontal bar, a striking head connected to the horizontal block, a drive head slidably connected to the vertical bar, a carriage slidably connected to the drive head, a toggle rod rotatably connected to the carriage, and an auxiliary plate A fixed to the toggle rod.

[0008] It also includes an auxiliary plate B fixed to the lever, the length of which is less than the length of the auxiliary plate A.

[0009] A method for manufacturing a water meter manufacturing system, comprising the following steps:

[0010] Step 1: Place the inlet and outlet of the water meter to be tested on the two fixing clamps respectively, and then slide the two fixing clamps upward so that the two fixing clamps and the two fixing rods work together to clamp and fix the two sides of the water meter.

[0011] Step 2: Connect two water pipes to the water inlet and outlet of the water meter respectively, and make the opening of the water pipe connected to the outlet face the location of the detection unit.

[0012] Step 3: Move the lever downwards. Once the moving head has slid to a stable equilibrium position, read the signal obtained by the displacement sensor and compare it with the value obtained by the water meter to test the accuracy of the water meter reading.

[0013] Step 4: Push the toggle lever to slide the detection unit upwards until the moving head returns to the water-receiving position, then operate the detection unit to rotate counterclockwise on the moving head;

[0014] Step 5: Rotate the detection unit back to its original position, and slide the lever down again to move the moving head, and read the signal obtained by the displacement sensor again;

[0015] Step Six: If the moving head continues to slide downwards to a position lower than the sum of its own weight and the weight of the detection part, it proves that the filter on the water meter under test has a poor filtration effect and fails the test. Conversely, if it slides downwards, it proves that the filter has a good filtration effect, meaning that the water meter has passed the test and can be shipped normally. Attached Figure Description

[0026] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 The diagram shows a schematic representation of an embodiment of the present invention that enables efficient and automatic detection of the filtration effect of a filter in a water meter with a filter, further illustrating this embodiment.

[0027] A water meter manufacturing system includes a fixed frame 101 and a vertical rod 201. Two fixing clamps 103 are slidably connected to the fixed frame 101. A moving head 301 is slidably connected to the vertical rod 201. A compression spring is fixed between the vertical rod 201 and the moving head 301. A scale 203 is provided on the vertical rod 201. A detection part 303 is rotatably connected to the moving head 301. A cylindrical rod is provided on the detection part 303, which is rotatably connected to the moving head 301 via the cylindrical rod. A filter plate 305 is slidably connected to the detection part 303. A toggle rod 501 is connected to the vertical rod 201. The toggle rod 501 can... The moving head 301 is able to move up and down on the vertical rod 201. A first motor that can drive the detection unit 303 to rotate is fixedly connected to the moving head 301. The output shaft of the first motor is fixedly connected to the cylindrical rod on the detection unit 303. A displacement sensor is fixedly connected to the vertical rod 201. The moving end of the displacement sensor is fixedly connected to the moving head 301. A first electric push rod that can push the filter plate 305 to slide is fixed to the detection unit 303. The filter plate 305 is provided with multiple through holes. The fixing frame 101 and the vertical rod 201 are fixed in a suitable position by screwing multiple bolts into the fixing frame 101 and the vertical rod 201.

[0028] The water meter with an internal filter is placed on two fixing clips 103. Then, two water pipes are connected to the water inlet and outlet of the water meter respectively, with the opening of the water pipe connected to the outlet facing the location of the detection unit 303. The water meter with an internal filter is a conventional setting in the prior art to extend the service life of the water meter and ensure that the water meter has a longer service life. It is very common and mature in the prior art, so it will not be described in detail here. Then, water with impurities is continuously introduced from the water pipe connected to the inlet, so that the water with impurities flows through the water meter with an internal filter and is gradually discharged from the water pipe at the outlet into the detection unit 303.

[0029] As the above operations continue, the overall weight of the detection unit 303 will continuously increase. During this process, the lever 501 will always be pressed against the lower side of the cylindrical rod, thus ensuring that the vertical height of the detection unit 303 remains unchanged during the process of adding water to the detection unit 303. This ensures that the water pipe at the outlet can smoothly enter the detection unit 303. After the addition work is completed, the lever 501 can be moved downward. At this time, due to the increase in the overall weight of the detection unit 303, the moving head 301 will gradually overcome the elastic force of the tension spring and move downward, so that the moving head 301 will gradually slide downward on the vertical rod 201. When the moving head 301 slides to a stable equilibrium position, the signal obtained by the displacement sensor can be read to determine the overall weight increase of the detection unit 303, that is, to determine the overall water content in the detection unit 303. After reading, the reading value can be compared with the value obtained by the water meter to determine whether the display value of the water meter is accurate, thus performing an accuracy test on the water meter before it leaves the factory.

[0030] Meanwhile, if the staff is always next to the equipment, they can also read the scale on the ruler 203 that the moving head 301 is facing, and then manually obtain the overall weight increase of the detection unit 303, and then make a manual comparison, thereby further ensuring the reliability of the detection results of the equipment.

[0031] After confirming the accuracy of the water meter reading, the filter plate 305 can be slid until it completely blocks the upper part of the detection unit 303. Then, the lever 501 can be slid upwards, pushing the detection unit 303 upwards until the moving head 301 returns to its water-receiving position. The detection unit 303 is then rotated counter-clockwise on the moving head 301, causing all the water inside to drain from the multiple through-holes on the filter plate 305. If both water and impurities are present in the detection unit 303, the impurities will be unable to drain through the through-holes. The detection unit 303 is then rotated back to its original position, and the lever 501 is slid down again, so that the moving head 301 is only subjected to the gravity provided by the detection unit 303. The spring force provides movement, and the signal obtained by the displacement sensor can be read again to automatically obtain the sliding status of the moving head 301. If the moving head 301 still slides downward to a position lower than the sum of its own weight and the weight of the detection unit 303, it proves that there are impurities inside the detection unit 303. This proves that the filtration effect of the filter on the water meter being tested is poor, and impurities will still enter the water meter. This inevitably results in some impurities remaining in the water meter, thus affecting the service life of the water meter. Conversely, it proves that the filtration effect of the filter is good and can achieve the ideal filtration effect. Thus, the above structure achieves the purpose of efficient and automatic detection of the filtration effect of the filter in the water meter with filter.

[0032] See Figure 1 , Figure 8 , Figure 9 The diagram shows a schematic representation of an embodiment of the invention that facilitates fixing of the water meter.

[0033] It also includes two fixing rods 102 fixed to the fixing frame 101. The two fixing rods 102 are respectively located directly above the two fixing clamps 103. The fixing frame 101 is fixed with two second electric push rods of the fixing rods 102. The telescopic rods of the two second electric push rods are respectively fixed to the two fixing clamps 103.

[0034] When placing the water meter, the water inlet and outlet of the water meter are placed on the two fixing clips 103 respectively. Then, by operating the two fixing clips 103 to slide upward, the two fixing clips 103 and the two fixing rods 102 cooperate to clamp and fix the two sides of the water meter, thereby facilitating subsequent testing operations.

[0035] See Figure 2-3 The diagram shows a schematic representation of an embodiment of the present invention that facilitates the long-term maintenance of the multiple through holes on the filter plate 305.

[0036] It also includes an arc-shaped brush 306 fixed to the detection unit 303.

[0037] During the screening of water and impurities in the detection section 303 using the filter plate 305, the filter plate 305 can be periodically slid back and forth on the detection section 303, and the arc-shaped brush 306 can be used to brush the lower side of the filter plate 305, thereby brushing the multiple through holes on the filter plate 305. This automatically removes the impurities that are stuck to the filter plate 305 without manual intervention, ensuring that the filter plate 305 can complete the screening of water and impurities efficiently and for a long time, providing convenience for subsequent testing work.

[0038] See Figure 2 , Figure 4 , Figure 5 and Figure 9 The diagram shows a further embodiment of the present invention that facilitates the long-term maintenance of the plurality of through holes on the filter plate 305.

[0039] It also includes a horizontal bar 202 fixed to the vertical bar 201, a horizontal block 601 slidably connected to the horizontal bar 202, a striking head 602 connected to the horizontal block 601, a drive head 401 slidably connected to the vertical bar 201, a slide 402 slidably connected to the drive head 401, a toggle lever 501 rotatably connected to the slide 402, an auxiliary plate A502 fixedly connected to the toggle lever 501, a first motor fixedly connected to the vertical bar 201, a first lead screw fixedly connected to the output shaft of the first motor, the first lead screw being threadedly connected to the drive head 401, a third electric push rod fixedly connected to the drive head 401 capable of pushing the slide 402 to slide, a second motor fixedly connected to the slide 402 capable of driving the toggle lever 501 to rotate, and a fourth electric push rod fixedly connected to the horizontal bar 202 capable of pushing the horizontal block 601 to slide.

[0040] When it is necessary to move the lever 501, the drive head 401 can be driven to slide on the vertical rod 201, thereby causing the slide 402 to slide, and then the slide 402 can be used to drive the lever 501 to slide up and down.

[0041] During operation, the drive head 401 can be periodically slid upwards, moving the filter plate 305 to a position offset from the striking head 602, until the filter plate 305 is above the striking head 602. Then, the filter plate 305 is slid back, placing it tangent to the striking head 602. The actuating lever 501 can then rotate on the slide 402, causing the auxiliary plate A502 to move the cylindrical rod on the detection unit 303 upwards, thus moving the filter plate 305 away from the striking head. The head 602 then slides on the drive head 401, causing the auxiliary plate A502 to gradually shift away from the cylindrical rod. This causes the detection part 303 to quickly reset downwards, resulting in a forceful impact between the filter plate 305 and the striking head 602. This vibration loosens the impurities blocking the multiple through holes on the filter plate 305, further facilitating the removal of the impurities stuck to the filter plate 305 and achieving the effect of keeping the multiple through holes on the filter plate 305 unobstructed for a long time.

[0042] See Figure 5 The diagram shows a further embodiment of the invention that facilitates the long-term maintenance of the multiple through holes on the filter plate 305.

[0043] It also includes an auxiliary plate B503 fixed to the lever 501, the length of which is less than the length of the auxiliary plate A502.

[0044] When the filter plate 305 is driven to perform multiple power-charging tapping operations by rotating the lever 501 and using the movement trajectory of the auxiliary plate A502, the rotation direction of the lever 501 can be changed, and the auxiliary plate B503 can then take on the task of moving the detection unit 303. Subsequently, the slide 402 is operated to slide on the drive head 401, and the auxiliary plate B503 is used to perform power-charging tapping operations, thereby providing power-charging tapping of the filter plate 305 with different forces. This further facilitates the loosening of impurities in the multiple through holes on the filter plate 305, making it easier to keep the multiple through holes on the filter plate 305 unobstructed for a long time.

[0045] See Figure 7 The diagram shows a further embodiment of the invention that facilitates keeping the plurality of through holes on the filter plate 305 unobstructed.

[0046] The transverse block 601 is slidably connected to the striking head 602, and a fourth electric push rod that can push the striking head 602 to slide is fixed on the transverse block 601.

[0047] During the power-charging tapping process using the tapping head 602, the tapping head 602 can slide on the transverse block 601, thereby changing the tapping position between the tapping head 602 and the filter plate 305, thus changing the contact position of the power-charging tapping. It can also slide on the crossbar 202 in conjunction with the transverse block 601, thereby further changing the power-charging tapping position, thus providing a more comprehensive tapping effect for the filter plate 305, and further facilitating the keeping of the multiple through holes on the filter plate 305 unobstructed.

[0048] See Figure 2-4 The diagram shows a schematic representation of an embodiment of the present invention that facilitates the removal of all impurities remaining in the detection unit 303, ensuring the accuracy of subsequent detection results.

[0049] It also includes a striking plate 304 fixed to the detection unit 303.

[0050] During a test, it was found that the filter on the water meter had poor filtration efficiency, indicating a large amount of impurities in the detection section 303. The detection section 303 was then rotated on the moving head 301 to empty the impurities from the detection section 303. Subsequently, the sliding drive head 401 moved the striking plate 304 to a position directly above and forward-facing with the striking head 602. The rotation of the toggle lever 501 and the sliding of the slide 402 then caused the striking plate 304 and the striking head 602 to perform multiple, forceful strikes, loosening the impurities adhering to the detection section 303. This facilitated the complete removal of all impurities from the detection section 303, ensuring accurate subsequent test results.

[0051] See Figure 6The diagram illustrates an embodiment of ensuring the operational stability of the device according to the present invention, further.

[0052] It also includes a rotating rod 204 rotatably connected to the vertical rod 201, a cylindrical rod 302 fixedly connected to the moving head 301, an angle sensor fixedly connected to the vertical rod 201, the moving end of the angle sensor fixedly connected to the rotating rod 204, a third motor capable of driving the rotating rod 204 to rotate fixedly connected to the vertical rod 201, and a pressure sensor provided on the cylindrical rod 302.

[0053] When the displacement sensor receives a signal, the rotating rod 204 can be rotated until it contacts the cylindrical rod 302. At this time, the pressure sensor receives a signal, and the height of the moving head 301 can be further determined by the signal obtained by the angle sensor. Thus, the height of the moving head 301 can be more accurately determined by the cooperation of the angle sensor and the displacement sensor, avoiding the situation where a sensor is damaged, which would directly lead to the distortion of the detection results.

[0054] Meanwhile, if the power source driving the drive head 401 to move fails, causing the drive head 401 to be unable to move at the lowest position of the vertical rod 201, the moving head 301 can be temporarily moved by rotating the rotating rod 204, which in turn moves the cylindrical rod 302. This allows the equipment to complete subsequent testing work without stopping normal operation, ensuring the stability of the equipment's operation.

[0055] A method for manufacturing a water meter manufacturing system, comprising the following steps:

[0056] Step 1: Place the inlet and outlet of the water meter to be tested on the two fixing clips 103 respectively, and then operate the two fixing clips 103 to slide upward, so that the two fixing clips 103 and the two fixing rods 102 cooperate to clamp and fix the two sides of the water meter.

[0057] Step 2: Connect two water pipes to the water inlet and outlet of the water meter respectively, and make the opening of the water pipe connected to the outlet face the location of the detection unit 303.

[0058] Step 3: Move the lever 501 downwards. When the moving head 301 slides to a stable equilibrium position, read the signal obtained by the displacement sensor and compare it with the value obtained by the water meter to test the accuracy of the water meter reading.

[0059] Step 4: Push the detection unit 303 upward with the lever 501 until the moving head 301 returns to the water-receiving position, and then operate the detection unit 303 to rotate counterclockwise on the moving head 301.

[0060] Step 5: Rotate the detection unit 303 back to its original position, and slide the lever 501 down again to move the moving head 301, and read the signal obtained by the displacement sensor again;

[0061] Step Six: If the moving head 301 continues to slide downwards to a position lower than the sum of its own weight and the weight of the detection unit 303, it proves that the filter on the water meter under test has a poor filtration effect and fails the test. Conversely, if it slides downwards, it proves that the filter has a good filtration effect, meaning that the water meter has passed the test and can be shipped out normally.

[0062] The water meter manufactured by the aforementioned water meter manufacturing system has a filter that has undergone filtration effect testing.
