Description

Technical Field

[0001] This utility model relates to the field of water meter calibration technology, and in particular to a water meter calibration device. Background Technology

[0002] Water meters are flow meters that calculate the volume of water flowing through a tap water pipe by measuring the direct mechanical movement of the movable wall volume measuring chamber or the effect of water flow velocity on the impeller. They are widely used in industries such as tap water, heating, and chemicals. National metrological verification regulations stipulate that water meter manufacturers or metrology departments must verify the error of water meters at three flow points: nominal flow rate, boundary flow rate, and minimum flow rate. After verification, the water inside the water meter needs to be emptied before loading. In existing technologies, loading and unloading of water meters during verification is usually done manually or automatically by robotic arms. However, manual loading and unloading can lead to water spillage due to worker fatigue or forgetting to empty the water before removing the water meter, resulting in water everywhere. When using robotic arms to unload, the large rotation required when emptying water can cause water to splash out, creating a damp working environment and affecting work efficiency.

[0024] Example 1

[0025] See attached document Figure 1-4This application provides a water meter calibration device, including a frame 1, on which a calibration platform 2 is provided. The calibration platform 2 includes multiple sets of clamps 3 that slide left and right. The clamps 3 are used to place and fix water meters 32. Each set of clamps 3 is rotatably connected to the frame 1. By rotating the clamps 3, the water meter 32 is tilted and water is poured out. The frame 1 is provided with several connecting rods 4, which are located on both sides of the clamps 3. Connecting heads 5 are provided on the connecting rods 4. During calibration, the connecting heads 5 are connected to the water meters 32, so that the water meters 32 are connected in series on the calibration platform 2 for testing. The water flows through the connecting heads 5 and the water meters 32, and the water is placed on the rightmost side of the platform. Link 4 is fixedly connected to the frame 1. The rightmost end of the connector 5 on the rightmost link 4 is connected to a water outlet pipe 6 for drainage. The water outlet pipe 6 can be connected to a water storage device. The remaining links 4 are slidably connected to the frame 1. A hydraulic rod 7 is provided on the frame 1, connected to the leftmost link 4. The hydraulic rod 7 extends and pushes the link 4. The connector 5 on the leftmost link 4 is connected to a water inlet pipe 8. The frame 1 is equipped with a water pump 33, which is connected to a water supply tank via a pipe. The outlet end of the water pump 33 is equipped with an inlet valve 34 and a flow meter 35. The inlet pipe 8 is connected to the flow meter 35. Water is pumped into the meter 33 for testing via the water pump 33. The calibration platform 2 is equipped with a photoelectric flow meter 9. During operation, the water meters 32 to be tested can be placed on the clamp 3 and fixed by manual or automated loading. The hydraulic rod 7 extends, pushing the leftmost connecting rod 4 to the right, causing the connector 5 on it to connect with the water meter 32. The hydraulic rod 7 continues to extend until all the water meters 32 and connectors 5 are connected in series. The water pump 33 is then started, and water is pumped into the meter 33. The water flows sequentially from the inlet pipe 8 through the water meter 32, and is detected and processed by the photoelectric flow meter 9. After completion, the hydraulic rod 7 retracts, and each of the clamps 3 and the connecting rod 4 resets. At this time, the water meter 32 and the connector 5 separate. The clamps 3 are rotated to tilt and empty the water from the water meter 32. After emptying, the meter is reset, and the meter can be manually or automatically removed and collected separately as good and bad products. The structure is simple. The clamps 3 fix the water meter 32 and raise the positioning angle of the water meter 32, making it easier for the photoelectric flow meter 9 to detect. After verification, the water in the water meter 32 can be automatically emptied, preventing water from splashing outside and causing a humid working environment, thus improving work efficiency.

[0026] Specifically, an L-shaped plate 10 is slidably connected to the frame 1. A slide rail 30 is provided on the frame 1, and a slider 31 is fitted onto the slide rail 30. The L-shaped plate 10 is mounted on the slider 31 to ensure smooth and stable sliding of the L-shaped plate 10 back and forth. The L-shaped plates 10 are symmetrically arranged on the frame 1, and each set of symmetrically arranged L-shaped plates 10 is used in conjunction with a clamp 3. One end of a first spring 11 is connected to each side of the L-shaped plate 10, and the other end of the first spring 11 is connected to a fixing block 12. The fixing block 12 is fixed to the frame 1. The L-shaped plate 10 is extended by the hydraulic rod 7 through the first springs 11 on both sides, which pushes the clamp 3 to move and move the L-shaped plate 10 to the right. After retraction, the clamp 3 can return to the middle position. The clamp 3 is rotatably connected to the L-shaped plate 10. The L-shaped plate 10 is provided with a rotating device 13, which can be a motor, cylinder 16, or hydraulic cylinder, etc. The output end of the rotating device 13 is connected to the clamp 3. The clamp 3 is driven to rotate by the rotating device 13, so that the clamp 3 can rotate and tilt to pour water. The structure is simple.

[0027] Specifically, the clamp 3 includes a connecting bed 14, a pillow block 15, a cylinder 16, a chuck 17, and a connecting shaft 18. The connecting shaft 18 is fixedly connected to both ends of the connecting bed 14 and rotatably connected to the L-shaped plate 10. The rotating device 13 is connected to the connecting shaft 18. The rotating device 13 rotates to drive the connecting shaft 18 to rotate, thereby driving the connecting bed 14 to rotate. The pillow block 15 is connected to the connecting bed 14 and has an arc-shaped opening that conforms to the shape of the water meter 32 for easy placement of the water meter 32. The two cylinders 16 are fixedly connected to both sides of the connecting bed 14. The chuck 17 is installed on the output end of the cylinder 16. The cylinder 16 extends to drive the chuck 17 to clamp the water meter 32 for fixation and positioning. The structure is simple.

[0028] Specifically, the frame 1 is provided with a light rod 19, and a linear bearing 20 is connected to the light rod 19. The connecting rod 4 is connected to the linear bearing 20. There are two light rods 19, which are fixedly connected to the frame 1. The linear bearing 20 is sleeved on the light rod 19, and the connecting rod 4 is installed on the linear bearing 20 to improve the sliding stability of the connecting rod 4.

[0029] Specifically, the light rod 19 is fitted with a second spring 21. One end of the second spring 21 is connected to the right end of the connecting rod 4, and the other end is connected to a fixing sleeve 22. The fixing sleeve 22 is fixed to the light rod 19. During operation, the connecting rod 4 works in conjunction with the second spring 21. When the hydraulic rod 7 extends, the connecting rod 4 can move to the right. When the hydraulic rod 7 resets, the connecting rod 4 resets under the elastic force of the second spring 21. Under the action of the first spring 11, the clamp 3 can reset back to the middle position after the hydraulic rod 7 retracts, so that the water meter 32 and the connector 5 reset and separate, making it convenient to rotate and pour out water, avoiding interference, and with a simple structure.

During operation, after the water meter 32 is placed and can be calibrated, the module 24 is driven to move forward, which in turn moves the horizontal plate 25 forward, thereby moving the photoelectric flow meter 9 above the water meter 32 for detection. After the detection is completed, the module 24 is driven to move backward, which in turn moves the photoelectric flow meter 9 away from directly above the water meter 32, which facilitates the loading and unloading of the water meter 32. The structure is simple.

[0032] Specifically, the frame 1 is provided with a base plate 26, and the base plate 26 is provided with a water baffle 27. The water baffle 27 blocks and collects the spilled water, thus preventing the working environment from becoming damp.
