Description

Technical Field

[0001] This invention relates to the field of gas meter testing, specifically to an automatic power supply device used for gas meter testing. Background Technology

[0002] Currently, in the production and testing of wireless remote-reading smart gas meters, the core power supply solution for live-line testing is manual installation of dry cell batteries. This traditional technical solution has multiple structural defects, severely restricting testing efficiency and accuracy, and cannot adapt to the upgrade requirements of automated testing production lines. The specific technical defects are as follows:

[0003] First, the management of dry cell battery consumables is chaotic, and testing costs are high. In large-scale batch testing scenarios, the number of dry cell batteries required for testing is enormous. New and old batteries, fully charged batteries, and depleted batteries cannot be quickly distinguished, leading to frequent instances of battery mixing and misuse of faulty batteries. This directly results in distorted data from gas meter low-voltage detection and valve control function testing, leading to unstable test pass rates. Furthermore, dry cell batteries are disposable consumables, resulting in high long-term consumable costs. The recycling and disposal of used batteries is cumbersome, further increasing the production and testing costs for enterprises.

[0004] Secondly, the repeated battery installation and removal is cumbersome and inefficient. In the industry's standard production and verification process, gas meters are not pre-installed with dry cell batteries before leaving the factory to avoid long-term static storage leading to battery depletion and leakage. This results in the testing process requiring multiple battery installations and removals: the meter manufacturer installs the battery for production testing and removes it after testing; the metrological verification agency requires a second battery installation and removal after verification. This repeated installation and removal work is labor-intensive and significantly reduces the overall production and verification efficiency of gas meters, making it unsuitable for large-scale production capacity requirements.

[0005] Third, the inability to achieve variable voltage output prevents the accurate completion of core testing items. The low-voltage valve shut-off function of a gas meter is a core safety testing item, requiring a gradient variable voltage power supply test to verify the meter's low-voltage protection performance. Traditional dry-cell batteries, however, provide a fixed voltage output and cannot adjust the power supply voltage. They can only perform routine power-on testing and cannot accurately conduct tests on critical items such as low-voltage threshold valve shut-off and voltage fluctuation adaptability, resulting in blind spots and severely insufficient testing completeness and accuracy.

[0006] Fourth, poor adaptability and incompatibility with multiple meter specifications make automation upgrades difficult. Existing gas meters have diverse battery compartment layouts and electrode polarity arrangements. Even with the same four AA battery power supply specification, battery compartments have various structures, including 2 rows and 2 columns horizontally, 4 rows and 1 column horizontally, and 1 row and 4 columns vertically. Each layout corresponds to four different electrode polarity arrangements, including left-side top negative and bottom positive, left-side top positive and bottom negative, right-side top negative and bottom positive, and right-side top positive and bottom negative. No universal power supply equipment on the market is compatible with all structural types. Furthermore, existing testing stations lack a matching automatic power supply structure, relying solely on manual battery installation and removal, making automated power-on and power-off impossible. This contradicts the industry trend of automated meter testing upgrades, resulting in high equipment modification costs and significant adaptation difficulties.

[0007] In summary, existing gas meter testing power supply technology suffers from multiple technical bottlenecks, including chaotic consumable management, cumbersome procedures, non-adjustable voltage, poor meter compatibility, and inability to automate. There is an urgent need to develop an automated power supply device that is compatible with multiple battery compartments, adaptive to electrode polarity, adjustable in voltage, and adaptable to existing testing stations, in order to solve the industry's technical pain points.

[0027] 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.

[0028] Example 1: Please refer to Figures 1-7 The figure shows an automatic power supply device for testing a gas meter, including: a profile frame 1 and an operating table 2 fixed on the profile frame 1. Multiple testing seats 5 are distributed in a straight line at equal intervals above the operating table 2, and the testing seats 5 are fixedly suspended on the profile frame 1. A gas meter 6 is placed above each testing seat 5. The gas inlet and outlet of the gas meter 6 face upwards. A gas docking component is also provided above the gas meter 6. The gas docking component is used to detect the flow of gas inside the gas meter 6.

[0029] It also includes: a power supply unit for simultaneously supplying power to each gas meter 6. The power supply unit includes a crossbar 17, and a number of limiting plates 18, the same as the number of detection bases 5, are fixedly mounted on the top of the crossbar 17. The limiting plates 18 have five L-shaped positioning through holes 19 inside. Electrical contacts 20 are distributed at the end of the positioning through holes 19 closest to the detection base 5, and springs 21 are fixedly installed between the electrical contacts 20 and the positioning through holes 19. Electrical wires 22 are also fixedly installed at the end of the electrical contacts 20 away from the detection base 5. Electric push rods 34 and cylinder push rods 35 are fixedly installed at both ends of the crossbar 17, and abutments are fixedly installed at the output ends of the electric push rods 34 and cylinder push rods 35, and the output ends of the two are arranged opposite to each other. Two symmetrically distributed fixing plates are fixedly installed on the profile frame 1. 37. Rubber pads 36 are fixed to the opposing end faces of the two fixing plates 37. The two abutments abut against the two rubber pads 36 respectively. The crossbar 17 can be grasped by the existing robotic arm and placed in front of several gas meters 6. The electrical contacts 20 are inserted into the battery compartment of the gas meter 6. Through the operation of the electric push rod 34 and the cylinder push rod 35, the abutments at the output ends of the two can be tightly pressed against the two rubber pads 36, thereby fixing the crossbar 17 to the profile frame 1. The two electrical contacts 20 can effectively contact the positive and negative poles in the battery compartment. Under the action of the programmable controller, the two electrical contacts 20 can be energized through the wire 22 to provide power to the gas meter. The voltage can be selectively supplied according to the model of the gas meter. The voltage is adjusted by a voltage regulator or transformer.

[0030] The gas docking component includes a support plate 8 fixed to the top of the profile frame 1. Each detection platform 5 has a dual-channel docking block 13 distributed above it. The two bottom ports of the dual channels of the dual-channel docking block 13 are fixedly equipped with rubber gaskets 14, and the two rubber gaskets 14 are respectively located above the gas inlet and gas outlet of the gas meter 6. The two top ports of the dual channels of the dual-channel docking block 13 are fixedly connected to gas pipes. One gas pipe can input detection gas into the gas meter 6, and the other gas pipe can recover the detection gas output from the gas meter 6. The rubber gaskets 14 can ensure the gas seal between the dual-channel docking block 13 and the gas meter 6. The dual-channel docking block 13 is located below the support plate 8, and the top of the dual-channel docking block 13 is fixedly equipped with a sliding rod 10 that slides through the support plate 8. A triggering component is set between several sliding rods 10, which can control several dual-channel docking blocks 13 to move up and down simultaneously.

[0031] The actuation component includes a movable plate 9 located above the support plate 8. Each slide rod 10 is fixedly inserted through the movable plate 9. A retaining ring 11 is slidably sleeved on the outer surface of each slide rod 10, and the retaining ring 11 is fixedly set with the support plate 8. A tension spring 12 is fixedly set between the retaining ring 11 and the movable plate 9, and the tension spring 12 is distributed on the outside of the slide rod 10. A first motor 15 is fixedly set on the upper end surface of the support plate 8, and a cam 16 is fixedly sleeved on the output end of the first motor 15. The outer wall of the cam 16 slides against the top surface of the movable plate 9. When the first motor 15 drives the cam 16 to rotate, it can press the movable plate 9 down. The first motor 15 is a self-locking motor, that is, the output shaft will not be rotated arbitrarily when the power is off.

[0032] Example 2: Please refer to Figures 1-7 This embodiment is another implementation of the above embodiment one. The front end face of the detection platform 5 is also fixed with two symmetrically distributed limiting blocks 7, and the gas meter 6 of the limiting blocks 7 plays a clamping and limiting role. Because the rubber gasket 14 is tightly assembled with the upper end face of the gas meter 6, when the dual-channel docking block 13 moves upward and separates from the gas meter 6, the rubber gasket 14 will plastically stick to the port of the gas meter 6. By limiting the limiting blocks 7, the dual-channel docking block 13 can be prevented from moving with the gas meter 6. An axial displacement component and a longitudinal displacement component are provided between the crossbar 17 and the profile frame 1.

[0033] The axial displacement component includes a second slide rail 29 suspended on the top of the profile frame 1. A sleeve 27 is fixedly installed on the top of the second slide rail 29, and a third motor 28 is fixed above the sleeve 27. The output end of the third motor 28 faces downward, and a second screw 30 is fixedly installed on the output end of the third motor 28. The second screw 30 rotates through the sleeve 27 and the second slide rail 29. The bottom of the second slide rail 29 is open. A threaded sleeve block 31 is threaded on the outer surface of the second screw 30, and the threaded sleeve block 31 is slidably embedded in the second slide rail 29. A fixed seat block 33 is fixedly installed at the bottom of the threaded sleeve block 31 through a hollow sleeve 32, and the fixed seat block 33 is fixed in the middle section of the crossbar 17. Through the drive of the sleeve 27 to the second screw 30, and the threaded assembly of the threaded sleeve block 31 and the second screw 30, the threaded sleeve block 31 can move up and down inside the second slide rail 29 with the hollow sleeve 32 to adjust the height position of the crossbar 17.

[0034] The longitudinal displacement component includes a first slide rail 24 arranged longitudinally, a first screw 26 rotatably mounted inside the first slide rail 24, a sleeve 27 slidably embedded in the first slide rail 24, and the sleeve 27 threadedly mounted on the outside of the first screw 26. A second motor 25 is fixedly mounted at one end of the first slide rail 24, and the output end of the second motor 25 is fixedly mounted to the end of the first screw 26 via a coupling. A support plate 23 is also fixedly mounted between the top of the first slide rail 24 and the profile frame 1. By driving the first screw 26 through the second motor 25, the sleeve 27 can move longitudinally along the second slide rail 29.

[0035] The inner diameter of the hollow sleeve 32 is larger than the outer diameter of the second screw 30, which means that as the threaded sleeve block 31 moves downward, the hollow sleeve 32 can also retract into the interior of the second slide rail 29 for storage.

[0036] The position of the crossbar 17 can be adjusted by the drive of the second motor 25 and the third motor 28. It should be noted that the distance between two adjacent limit plates 18 is consistent with the distance between two adjacent detection bases 5. After the gas meters 6 are placed neatly, a limit plate 18 can be distributed in front of the battery compartment of each gas meter 6. According to the internal distribution of the battery compartment, the positions of the two electrical contacts 20 and the spring 21 can be adjusted in advance to ensure that when the limit plate 18 moves towards the gas meter 6, the two electrical contacts 20 can be effectively connected with the positive and negative terminals in the battery compartment. Power is directly supplied to the gas meter 6 through the wire 22, thereby realizing the simultaneous direct power supply to multiple gas meters 6. Through the automated design, the efficiency of powering multiple gas meters 6 can be effectively improved.

[0037] Working principle: When testing the power supply of multiple gas meters 6 simultaneously, the gas meters 6 are first placed orderly on the testing platform 5. Then, the first motor 15 drives the cam 16. After the cam 16 rotates half a turn, it presses down on the movable plate 9, thereby allowing the two lower ports of the dual-channel docking block 13 to connect with the two ports of the gas meters 6. The operator can use a robotic arm to pick up and adjust the position of the crossbar 17, so that the crossbar 17 is placed horizontally in front of the gas meters 6. At the same time, each set of electrical contacts 20 must be aligned. All can be inserted into the corresponding operating table 2. Two of the five flexible electrical contacts 20 can effectively contact the electrodes in the battery compartment of the gas meter 6. Then, through the operation of the electric push rod 34 and the cylinder push rod 35, the output ends of both can be pressed against the rubber pad 36, thereby stably fixing the crossbar 17 to the profile frame 1. At this time, the robot can leave the crossbar 17. Then, under the control of the programmable controller, the two electrical contacts 20 that are in contact with the electrodes in the battery compartment of the gas meter 6 can be energized, thus powering the gas meter 6.

[0038] refer to Figure 6 The five electrical contacts 20 are marked with symbols a, b, c, d, and e. The center distance between ab and ad is the center distance between two AA batteries arranged side by side. The center distance between ac and ae is the center distance between the first and fourth AA batteries arranged side by side. Therefore, the two contacts ab can power the battery compartments in a vertical 2x2 grid, the two contacts ad can power the battery compartments in a horizontal 2x2 grid, the two contacts ac can power the battery compartments in a vertical 1x4 grid, and the two contacts ae can power the battery compartments in a vertical and horizontal 4x1 grid. Depending on the polarity of the electrodes in different battery compartments, a custom-designed programmable power supply can be used to enable only the two required contacts for power supply. The electrodes and voltage of the two contacts can be set.

[0039] This design also achieves the following effects:

[0040] 1. The power supply device structure can be directly installed on the existing gas meter testing station without modifying the original testing station's mechanical structure, circuit system, or control program. This achieves seamless adaptation and rapid installation, significantly reducing equipment upgrade and modification costs. Unlike traditional power supply solutions that require overall modification of the testing equipment, this device is compatible with various existing testing equipment and has extremely strong versatility.

[0041] 2. For the various irregular layout structures of the existing gas meter's 4-cell AA battery compartment (2 rows 2 columns horizontal, 4 rows 1 column horizontal, 1 row 4 columns vertical), an adaptive and fitting power supply docking mechanism is designed. It is compatible with all mainstream battery compartment installation space structures, solving the technical problem of the traditional power supply tooling having a single structure and being unable to adapt to multiple specifications, and realizing universal docking power supply for different models of gas meters.

[0042] 3. To address the industry pain point of disordered electrode polarity arrangement in the battery compartments of different gas meters, a software programmable configuration module is set up. It can automatically switch the positive and negative polarities of the power supply electrodes according to the electrode polarity parameters of the meter. It is compatible with all working conditions with different polarity arrangements on the left, right, top, and bottom sides. No manual adjustment of hardware wiring is required, and polarity self-adaptive matching is achieved, which completely solves the problems of power supply failure and detection failure caused by polarity mismatch.

[0043] 4. Abandoning the traditional fixed voltage power supply mode of dry batteries, a programmable adjustable voltage power supply scheme is adopted, which can output gradient variable voltage to accurately match the voltage requirements of core testing items such as low voltage valve closure, voltage adaptability, and low voltage protection of gas meters. This eliminates the detection blind spots of traditional testing technologies and significantly improves the detection accuracy and completeness of gas meters.

[0044] 5. It enables automated power-on, voltage stabilization, and automatic power-off upon completion of testing, replacing the traditional manual operation mode of repeatedly installing and removing batteries. It completely solves problems such as chaotic management of dry cell battery consumables, mixing of new and old batteries, and false detection due to insufficient power. It is compatible with the operation requirements of automated test line production lines, reduces labor costs, and improves batch testing efficiency and consistency.

[0045] 6. It integrates a mechanical adaptive docking structure, an automatic polarity switching circuit, an adjustable voltage control module, and a software configuration control system into one compact and highly integrated unit. It balances mechanical adaptability, electrical stability, and intelligent controllability, forming an integrated intelligent power supply tooling specifically for gas meter detection scenarios, filling a technological gap in the industry.
