Description

Technical Field

[0001] This utility model relates to the technical field of water meter performance testing devices, specifically an ultrasonic water meter module production performance testing device. Background Technology

[0002] Ultrasonic water meters are increasingly widely used in both residential and industrial water metering due to their significant advantages, including no moving parts, wide measuring range, high accuracy, and long service life. The core metering unit of an ultrasonic water meter is the ultrasonic meter module, whose performance directly determines the accuracy, stability, and reliability of the entire meter. Therefore, before the module leaves the factory, it must undergo comprehensive, rapid, and precise performance testing and calibration to ensure product quality.

[0003] A search revealed a patent, CN221198610U, for example, a flow detection device for manufacturing smart water meters. This device includes a workbench, a fixing unit, and an automatic water pipe docking unit. The fixing unit is located on the left side of the upper surface of the workbench. The fixing unit comprises a lower fixing seat, a smart water meter, and a meter panel. The left side of the upper surface of the workbench is fixedly connected to the bottom ends of two lower fixing seats. The left and right ends of the smart water meter are respectively placed in the top grooves of the two lower fixing seats. The meter panel is located in the upper center of the smart water meter. The automatic water pipe docking unit is located on the right side of the upper surface of the workbench. This flow detection device for manufacturing smart water meters, by incorporating the automatic water pipe docking unit, allows the inlet pipe to automatically dock with the inlet of the smart water meter, saving time and manpower.

[0004] When using the weighing method for testing, air bubbles are easily drawn in as water flows directly from the module outlet into the weighing container (such as a bucket). If these bubbles burst or adhere to the container, they will cause unstable weighing readings, resulting in errors in the final volume conversion value and seriously affecting the accuracy of the test results. Utility Model Content

[0005] The purpose of this invention is to provide an ultrasonic water meter module production performance testing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic water meter module production performance testing device, including a workbench and a fixed base, the fixed base being installed on the top of the workbench, a water bucket being provided on one side of the workbench, and a weighing instrument being provided at the bottom of the water bucket;

[0007] A drain pipe is provided on one side of the fixing base, and the end of the drain pipe is embedded inside the water bucket.

[0008] A fixing plate is fixedly installed on the outer wall of the drain pipe, and an installation plate is fixedly connected to one end of the fixing plate. The installation plate is embedded in the inner wall of the water bucket.

[0009] As a further preferred embodiment of this technical solution, the bottom of the drain pipe is inclined toward the inner wall of the bucket.

[0010] As a further preferred embodiment of this technical solution, the mounting plate is provided with two connecting plates inside, each of the two connecting plates has a second movable plate at its top, and each of the two connecting plates has a limiting shaft fixedly connected to its bottom. The limiting shaft is embedded in the inner wall of the limiting groove, which is located inside the water bucket.

[0011] As a further preferred embodiment of this technical solution, multiple limiting grooves are evenly arranged.

[0012] As a further preferred embodiment of this technical solution, a spring is installed between the two connecting plates.

[0013] As a further preferred embodiment of this technical solution, a first movable plate is fixedly connected to one side of the top of the connecting plate, and the first movable plate is slidably installed inside the mounting plate.

[0014] As a further preferred embodiment of this technical solution, the top of the connecting plate is provided with a sliding groove, the inner wall of the sliding groove is slidably connected with a slider, the slider is fixedly installed at the bottom end of the second moving plate, and a slot is provided on one side of the second moving plate, the slot being opened at the top of the fixed plate.

[0015] This utility model provides a device for testing the production performance of ultrasonic water meter modules, which has the following beneficial effects:

[0016] (1) This utility model connects the water meter outlet end to the water bucket via a drain pipe. During operation, one end of the drain pipe is first connected to the outlet end of the ultrasonic water meter via an installation structure. Then, the inlet end of the ultrasonic water meter is connected to the inlet pipe. The water meter is then fixed via a fixing structure. Finally, water is pumped in and the water flows into the water bucket through the connection between the water meter and the drain pipe. The weight of the water is measured by a weighing instrument and converted into volume. The volume is compared with the water meter measurement value to determine whether the water meter measurement is accurate. This achieves the purpose of testing the production performance of the ultrasonic water meter module. The device, through the connection of the drain pipe, allows the measured water flow to be released smoothly and slowly, minimizing the generation of air bubbles in the water bucket and ensuring the accuracy of the test results.

[0017] (2) By fixing the mounting plate inside the water bucket, when the drain pipe is installed inside the water bucket, the two second moving plates are first moved inward. The movement of the second moving plates drives the movement of the connecting plate, and the movement of the connecting plate drives the movement of the limiting shaft, so that the limiting shaft slides into the mounting plate. Then the mounting plate is embedded into the inner wall of the water bucket. After the drain pipe is placed, the two second moving plates are moved outward, so that the limiting shaft slides out from the mounting plate and is embedded in the limiting groove, thereby fixing the mounting plate inside the water bucket. This prevents the drain pipe from shaking during operation and interfering with ultrasonic, electromagnetic and other flow meters, and helps to ensure the stability during detection.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] This utility model provides a technical solution: such as Figures 1 to 5 As shown in this embodiment, an ultrasonic water meter module production performance testing device includes a workbench 1 and a fixed base 2. The fixed base 2 is installed on the top of the workbench 1. A water bucket 3 is provided on one side of the workbench 1, and a weighing instrument 4 is provided at the bottom of the water bucket 3.

[0026] A drain pipe 5 is provided on one side of the fixing base 2, and the end of the drain pipe 5 is embedded inside the water bucket 3.

[0027] A fixing plate 6 is fixedly installed on the outer wall of the drain pipe 5, and an installation plate 7 is fixedly connected to one end of the fixing plate 6. The installation plate 7 is embedded in the inner wall of the water bucket 3.

[0028] The existing patent CN221198610U discloses a flow detection device for the production and processing of smart water meters. This patent discloses the workbench 1, fixed base 2, water bucket 3 and weighing instrument 4 proposed in this application. The technical means will not be described in detail here.

[0029] One end of the drain pipe 5 is connected to the outlet of the water meter through an installation structure. The installation method of this installation structure can be a traditional flange connection, which will not be described in detail here.

[0030] During operation, firstly, one end of the drain pipe 5 is connected to the outlet end of the ultrasonic water meter through the installation structure. Then, the inlet end of the ultrasonic water meter is connected to the inlet pipe. Next, the water meter is fixed through the fixing structure. Finally, water is pumped in, and the water flows through the connection between the water meter and the drain pipe 5 and finally enters the water tank 3. The weight of the water is measured by the weighing instrument 4, converted into volume, and compared with the water meter measurement value to determine whether the water meter measurement is accurate, so as to achieve the purpose of testing the production performance of the ultrasonic water meter module.

[0031] This device, through the connection of the drain pipe 5, allows the measuring water to be released smoothly and slowly, minimizing the generation of air bubbles in the water tank 3, thereby ensuring the accuracy of the test results.

[0032] like Figure 4 As shown, the bottom of the drain pipe 5 is inclined toward the inner wall of the bucket 3.

[0033] This provides a natural guide for the water flow, which will mainly spread upwards along the inner wall of bucket 3, instead of directly impacting the hard bottom of the bucket, thus avoiding the final energy burst and bubble entrainment.

[0034] like Figure 3 and Figure 4 As shown, the mounting plate 7 has two connecting plates 9 inside. The top of each connecting plate 9 is provided with a second movable plate 12. The bottom of each connecting plate 9 is fixedly connected to a limiting shaft 10. The limiting shaft 10 is embedded in the inner wall of the limiting groove 13, which is opened inside the water bucket 3.

[0035] The interior of the bucket 3 has a mounting groove for mounting the mounting plate 7;

[0036] When installing the drain pipe 5 into the water bucket 3, first move the two second moving plates 12 inward. The movement of the second moving plates 12 drives the movement of the connecting plate 9, and the movement of the connecting plate 9 drives the movement of the limiting shaft 10, so that the limiting shaft 10 slides into the mounting plate 7. Then, embed the mounting plate 7 into the inner wall of the water bucket 3. After placing the drain pipe 5, move the two second moving plates 12 outward, so that the limiting shaft 10 slides out from the mounting plate 7 and is embedded in the limiting groove 13, thereby fixing the mounting plate 7 in the water bucket 3. This prevents the drain pipe 5 from shaking during operation and interfering with ultrasonic, electromagnetic and other flow meters, and helps to ensure the stability during detection.

[0037] like Figure 3 As shown, multiple limiting grooves 13 are evenly arranged.

[0038] During operation, the distance between the bottom of the drain pipe 5 and the bottom of the water bucket 3 is adjusted according to different test water volumes, so that the limiting shaft 10 is embedded in the limiting groove 13 at different heights. The outlet depth of the drain pipe 5 can be adjusted for different test flow points, so that the most stable outflow state with the fewest bubbles can be achieved throughout the entire range, ensuring that the measurement at each flow point is carried out under optimal conditions.

[0039] like Figure 4 As shown, a spring 17 is installed between the two connecting plates 9.

[0040] The elastic potential energy of the spring 17 causes the two connecting plates 9 to always have a tendency to move outward, thereby making the limiting shaft 10 stably embedded in the limiting groove 13, which helps to improve the stability of the connection.

[0041] like Figure 3 and Figure 4 As shown, a first movable plate 11 is fixedly connected to one side of the top of the connecting plate 9, and the first movable plate 11 is slidably installed inside the mounting plate 7.

[0042] The first movable plate 11 can be pressed inward from the side to contact the mounting plate 7 and the water bucket 3 for fixed connection, adapting to different operating methods.

[0043] like Figure 5 As shown, a groove 15 is provided on the top of the connecting plate 9, and a slider 14 is slidably connected to the inner wall of the groove 15. The slider 14 is fixedly installed at the bottom of the second moving plate 12. A slot 16 is provided on one side of the second moving plate 12, and the slot 16 is located on the top of the fixed plate 6.

[0044] When the drain pipe 5 needs to be removed from the bucket 3 for maintenance, first press the two second moving plates 12 inward. When the second moving plate 12 is located on one side of the slot 16, push the second moving plate 12 into the slot 16. At this time, the slider 14 slides on the inner wall of the slide groove 15. When the second moving plate 12 slides into the slot 16, the slot 16 limits the second moving plate 12 to prevent it from being released due to the elastic potential energy of the spring 17. This makes the outer wall of the mounting plate 7 a whole plane when in the maintenance state, which is convenient for installation and maintenance.

[0045] This utility model provides a device for testing the production performance of ultrasonic water meter modules, the specific working principle of which is as follows:

[0046] During operation, firstly, the two second moving plates 12 or the two first moving plates 11 are moved inward. The movement of the second moving plates 12 or the first moving plates 11 drives the movement of the connecting plate 9. The movement of the connecting plate 9 drives the movement of the limiting shaft 10, so that the limiting shaft 10 slides into the mounting plate 7. Then, the mounting plate 7 is embedded into the inner wall of the water bucket 3, and the drain pipe 5 is placed into the water bucket 3 with the inclined opening at the bottom of the drain pipe 5 facing the inner wall of the water bucket 3.

[0047] After placing the drain pipe 5, loosen the two second moving plates 12 or the first moving plate 11. Release the elastic potential energy through the spring 17 to move the two connecting plates 9 outward, so that the limiting shaft 10 is embedded into the limiting groove 13 and the mounting plate 7 is fixedly installed in the bucket 3.

[0048] Then, one end of the drain pipe 5 is connected to the outlet end of the ultrasonic water meter through the installation structure, and the inlet end of the ultrasonic water meter is connected to the inlet pipe. The water meter is then fixed through the fixing structure. Finally, water is pumped in, and the water flows through the connection between the water meter and the drain pipe 5 and finally enters the water tank 3. The weight of the water is measured by the weighing instrument 4, converted into volume, and compared with the water meter measurement value to determine whether the water meter measurement is accurate, so as to achieve the purpose of testing the production performance of the ultrasonic water meter module.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
