Description

Technical Field

[0001] This application relates to the field of product testing, and in particular to a water meter factory testing device. Background Technology

[0002] Water meters, as key equipment for measuring water use in both residential and industrial applications, play a vital role in water resource management and economic activities. With continuous societal development, the demand for rational water resource utilization and accurate metering is increasing. The quality and performance of water meters directly affect the accuracy of water measurement and the interests of both supply and demand sides. Against this backdrop, the water meter manufacturing industry is also continuously developing and progressing, with its production scale expanding and product variety gradually increasing to meet the needs of different scenarios and users. However, ensuring the quality of water meters relies heavily on rigorous testing procedures. This process plays a decisive role in ensuring that products meet relevant standards and requirements, directly impacting the product's reliability in the market and user trust. In the past, two main testing methods were typically used in water meter manufacturing to ensure quality. One method is manual sampling, where inspectors, relying on their experience and skills, randomly select a certain number of water meters from the production line for testing. This method requires inspectors to carefully observe the appearance and operational performance of the water meters, manually recording and comparing relevant data to determine whether the water meters are qualified. Another type is semi-automated testing equipment, which combines some automation technology with manual operation. For example, it uses simple mechanical devices to perform preliminary tests on water meters, followed by further data analysis and judgment by operators. Both methods can ensure water meter quality to a certain extent, but they both have significant limitations. Traditional manual sampling and semi-automated testing equipment are no longer sufficient to meet the development needs of modern water meter manufacturing. Manual sampling is inefficient; in the face of large-scale production, it is impossible to comprehensively test every water meter, easily leading to some substandard products entering the market. Moreover, manual testing is susceptible to human error; different inspectors may have different judgment standards and operating habits, affecting the accuracy of the test results. While semi-automated testing equipment improves testing efficiency to some extent, it still relies heavily on manual operation, and its testing accuracy and functions are limited, making it difficult to meet the stringent requirements of large-scale, high-precision, and full-parameter testing in the era of IoT technology and smart water meters. Therefore, designing a device capable of automatically performing batch testing of water meters has become an urgent problem to be solved. Utility Model Content

[0003] The purpose of this application is to overcome the above-mentioned technical problems and provide a water meter factory testing device. A water meter factory testing device includes a base with multiple slots for placing water meters. An inlet pipe and an outlet pipe are positioned at the bottom of the base corresponding to each slot. The water meter has inlet and outlet pipes connected to both sides. A positioning mechanism within the base automatically connects the inlet pipes and outlet pipes. A flow meter is installed on the inlet pipe, and a water flow display is installed on the water meter. Using this technical solution, when the user uses the water meter, it is placed in the slot. The positioning mechanism automatically fixes the inlet and outlet pipes. Water enters the inlet pipe and flows out through the outlet pipe. The flow meter measures the water flow rate entering the water meter, and the water meter displays the water flow rate. By comparing the two data points, the quality of the water meter can be determined. Preferably, the base has a receiving cavity extending from the bottom of the slot to both symmetrical sides of the slot. The positioning mechanism includes sliding seats slidably connected within the receiving cavity, located on both sides of the slot. Inlet and outlet water pipes are respectively fixedly connected to the sliding seats on both sides. The ends of the inlet and outlet water pipes are provided with identical connecting structures. These connecting structures are used to connect and fix the inlet and outlet water pipes, and to automatically connect and fix the outlet and outlet water pipes. A driving component is provided within the receiving cavity to drive the sliding seats to move in opposite directions, thereby connecting the inlet and outlet water pipes and the connecting structure to each other. By adopting the above technical solution, when the user uses the water meter, the driving component drives the positioning seats to move in opposite directions, and the connecting structure connects the inlet and outlet water pipes, allowing water to be supplied for testing.

[0004] Preferably, the driving assembly includes a pair of wires, with a sliding seat threadedly connected to both ends of the pair of wires. A motor is fixedly connected within the receiving cavity, and the motor's output shaft is fixedly connected to the pair of wires. By adopting the above technical solution, when the user uses the device, the motor drives the pair of wires to rotate, which in turn causes the sliding seat to move towards or away from the water meter. This facilitates the connection structure moving towards or away from the water meter, making it easier to connect and separate the inlet conduit and the inlet pipe, as well as the outlet conduit and the outlet pipe. Preferably, the connection structure includes a connector fixedly connected to the inlet pipe, with the inlet pipe fixed inside the connector. The connector has a plug ring for inserting the inlet pipe, and the inner wall of the plug ring has a bevel. A pressure member is connected to the connector to press the inlet pipe and the inner wall of the plug ring together. By adopting the above technical solution, when the user uses the device, the bevel facilitates the insertion of the inlet pipe into the plug ring, and the pressure member presses against the connector, pressing the inlet pipe and the inner wall of the plug ring together, thus achieving the connection and fixation of the inlet pipe to the inlet conduit. Preferably, the pressure component includes a pressure ring sleeved on the inlet pipe, located between the sliding seat and the connecting joint. A pressure groove is formed on the side of the connecting joint near the pressure ring, and an inclined surface is formed on the inner wall of the pressure groove. A guide post is fixedly connected to the pressure ring, and the end of the guide post is slidably connected to the sliding seat and fixedly connected to a limiting part. By adopting the above technical solution, when the user operates the ribbon, the sliding seat moves in opposite directions, causing the inlet pipe to insert into the insertion ring. Simultaneously, the sliding seat pushes the pressure ring into the pressure groove, and the pressure ring applies pressure to the pressure groove, causing the connecting joint to more tightly abut against the side wall of the inlet pipe. Preferably, a return spring is sleeved on the pressure ring, located between the pressure ring and the connecting joint. By adopting the above technical solution, when the user operates the ribbon, as the pressure ring slides into the pressure groove, it compresses the return spring. When the sliding seat drives the inlet pipe to move in the opposite direction, the tension of the return spring facilitates the pressure ring's disengagement from the pressure groove. Preferably, the middle sections of both the inlet and outlet pipes are flexible hoses. By adopting the above technical solution, when the user uses the hose, the inlet and outlet water pipes can easily move in opposite directions with the sliding seat to connect and fix with the inlet and outlet water pipes without affecting the water flow. Preferably, the base is provided with a pressure component in the slot position; the pressure component includes a guide post, a pressure spring is sleeved on the guide post, and a pressure plate is slidably connected to the guide post. The pressure plate is L-shaped and is used to clamp onto the top of the water meter. By adopting the above technical solution, when the user installs the water meter, pulling the pressure plate compresses the pressure spring, making it easy for the water meter to clamp into the clamping position. Releasing the pressure plate, the pressure plate presses against the side wall and top of the water meter under the tension of the pressure spring, vertically fixing the water meter.

Detailed Implementation

[0007] The following will be combined with the appendix Figure 1-3 The technical solutions in the embodiments of this utility model are further described in detail below. The described embodiments are only possible technical implementations of this utility model, but are not limited thereto. Those skilled in the art can combine the embodiments of this utility model, and other embodiments obtained without creative labor are also within the protection scope of this utility model. This application mainly adopts a scheme of using a base with slotted stations and a positioning mechanism to test water meters, achieving the effect of automatic batch testing of water meters and improving testing efficiency and accuracy. The following is a further detailed description of this application. The water meter 3 factory testing device provided in the embodiment of this application includes a base 1, with multiple slotted stations for placing water meters 3 on the base 1. A receiving cavity 12 is opened in the base 1. Water inlet pipes 13 and water outlet pipes 14 are symmetrically arranged on both sides of the base 1. The water inlet pipes 13 and water outlet pipes 14 extend into the receiving cavity 12. The water inlet pipe 13 is used to introduce water into the water meter 3, and the water outlet pipe 14 is used to discharge water from the water meter 3. Water inlet pipes 31 and water outlet pipes 32 are symmetrically arranged on both sides of the water meter 3. The positioning mechanism 2 is located within the receiving cavity 12 of the base 1. It automatically connects and fixes the inlet conduit 13 and the inlet pipe 31, and automatically connects the outlet pipe 32 and the outlet conduit 14. A flow meter 16 is installed on the inlet pipe 31, and a water flow display 33 is installed on the water meter 3. This achieves the effect of automatically batch testing the water meters 3, improving testing efficiency and accuracy, and avoiding interference from human factors. This is possible because multiple slots can simultaneously hold multiple water meters 3 for testing. The positioning mechanism 2 enables automatic connection, which is convenient, fast, and reduces human error. The data comparison between the flow meter 16 and the water flow display 33 accurately determines the quality of the water meter 3.

[0008] The slot is located on the upper surface of the base 1 and is used to place the water meter 3 to be tested. The shape and size of the slot are adapted to the water meter 3, which can stably place the water meter 3 and prevent the water meter 3 from shaking during the testing process.

[0009] The base 1 is equipped with a pressure assembly 15 located in the slot. The pressure assembly includes a guide post 151, a pressure spring 152 sleeved on the guide post 151, and a pressure plate 153 slidably connected to the guide post 151. The pressure plate 153 is L-shaped and is used to snap onto the top of the water meter 3. When installing the water meter 3, pulling the pressure plate 153 compresses the pressure spring 152, making it easier for the water meter 3 to snap into the snap-fit ​​position 11. When the pressure plate 153 is released, it presses against the side wall and top of the water meter 3 under the tension of the pressure spring 152, thus vertically fixing the water meter 3.

[0010] The receiving cavity 12 extends from the bottom of the slot station to both symmetrical sides of the slot station. The receiving cavity 12 provides space for the installation and movement of the positioning mechanism 2. The inner wall of the receiving cavity 12 can be smoothed to reduce the frictional resistance when the positioning mechanism 2 moves. In addition to the conventional smooth inner wall, a lubricating coating can also be provided on the inner wall to further reduce friction.

[0011] These components work together to provide stable support and necessary water connection for the placement and testing of the water meter 3. The slot position ensures the positioning of the water meter 3. The inlet pipe 13 and the outlet pipe 14 enable water flow. The receiving cavity 12 creates conditions for the subsequent operation of the positioning mechanism 2.

[0012] Specifically, the positioning mechanism 2 includes two sliding seats 21, a connecting structure 22, and a drive assembly 23. The sliding seats 21 are slidably connected within the receiving cavity 12 and are located on both sides of the slot station. The sliding seats 21 can move linearly along the receiving cavity 12. Rollers can be installed at the bottom of the sliding seats 21 to further reduce friction during sliding and make the movement smoother.

[0013] The connecting structure 22 is fixed to the ends of the inlet pipe 13 and the outlet pipe 14, and is used to automatically connect and fix the inlet pipe 13 and the inlet pipe 31, and the outlet pipe 14 and the outlet pipe 32. Taking the connection between the connecting structure 22 and the inlet pipe 31 as an example, the connecting structure 22 includes a connector 221, a plug ring 222, a bevel, and a pressure member. The connector 221 is fixedly connected to the inlet pipe 13, and the inlet pipe 13 is fixed inside the connector 221. The plug ring 222 is formed inside the connector 221 for the inlet pipe 31 to be inserted into, and the bevel of its inner wall facilitates the insertion of the inlet pipe 31. The pressure member is used to press the inlet pipe 31 and the inner wall of the plug ring 222 together. The pressure member is ring-shaped and can be an elastic rubber ring with good elasticity and sealing performance; or it can be a metal spring sheet that provides stable pressure. The connector 221 can be made of plastic injection molding, which is low in cost and easy to process; the connector 221 and the water inlet pipe 13 can be fixed by means of adhesive bonding or snap-fit ​​connection to ensure a firm connection.

[0014] The pressure component includes a pressure ring 224 sleeved on the outside of the water inlet pipe 13. The pressure ring 224 is located between the sliding seat and the connecting joint. The connecting head 221 has a pressure groove 223 on the side near the pressure ring 224. The inner wall of the pressure groove 223 has an inclined surface. A limiting post 225 is fixedly connected to the pressure ring 224. The limiting post 225 is slidably connected to the sliding seat. The end of the limiting post 225 is fixedly connected to a limiting part. The connecting thread 231 drives the sliding seat 21 to move towards each other, so that the water inlet pipe 31 is inserted into the insertion ring 222. At the same time, the sliding seat 21 pushes the pressure ring 224 to be inserted into the pressure groove 223. The pressure ring 224 applies pressure to the pressure groove 223, so that the connecting head 221 abuts the side wall of the water inlet pipe 31 more tightly.

[0015] The drive assembly 23 is disposed within the receiving cavity 12 and is used to drive the sliding seats 21 to move towards each other. The drive assembly 23 includes a guide wire 231 and a motor 232. The sliding seats 21 are threadedly connected to both ends of the guide wire 231, and the output shaft of the motor 232 is fixedly connected to the guide wire 231. The motor 232 can be a stepper motor 232, which can precisely control the rotation angle and speed; or it can be a servo motor 232, which has higher precision and response speed. The surface of the guide wire 231 can be threaded to ensure the thread fit accuracy with the sliding seats 21. The motor 232 and the guide wire 231 can be connected by a coupling to ensure the stability of power transmission.

[0016] These components are combined together, and the drive assembly 23 drives the sliding seat 21 to move towards each other, so that the connection structure 22 connects and fixes the water inlet pipe 13 with the water inlet pipe 31, the water outlet pipe 14 and the water outlet pipe 32, realizing the automatic connection of the water circuit and facilitating the detection of the water meter 3.

[0017] Specifically, the flow meter 16 is installed on the inlet pipe 31 to measure the flow rate of water entering the water meter 3. The flow meter 16 can be an electromagnetic flow meter 16, which has high measurement accuracy and is not affected by factors such as fluid viscosity and density; or it can be an ultrasonic flow meter 16, which has the advantage of non-contact measurement and will not obstruct the fluid. The flow meter 16 is fixed to the inlet pipe 31 by means of flange connection or threaded connection to ensure the sealing and stability of the connection.

[0018] Specifically, a water flow indicator 33 is installed on the water meter 3 to display the water flow rate passing through the water meter 3. The water flow indicator 33 can be a digital display screen to display data clearly and intuitively; or it can be an analog display with a traditional display method. The water flow indicator 33 is connected to the sensing element inside the water meter 3 via a wire to acquire and display water flow data in real time.

[0019] The implementation principle of this embodiment is as follows: The water meter factory testing device of this embodiment has significant advantages and practicality. It can automatically perform batch testing on multiple water meters 3, greatly improving testing efficiency and solving the problem of low efficiency in traditional manual sampling and semi-automatic testing. Automatic connection of the water circuit is achieved through the positioning mechanism 2, avoiding interference from human factors and improving testing accuracy. Data comparison between the flow meter 16 and the water flow display 33 can accurately determine the quality of the water meter 3, ensuring the reliability of the test results. Compared with the prior art, this device has significant improvements and innovations in structure and function, meeting the needs of modern water meter manufacturing for large-scale, high-precision, and full-parameter testing. The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
