Description

Technical Field

[0001] This utility model belongs to the field of water meter technology, specifically a water meter that prevents self-rotation and dripping. Background Technology

[0002] A water meter is a measuring instrument used to measure water flow. Its primary function is to record water consumption so that water supply departments or users can manage water usage and settle bills. Its core function is to accurately measure the amount of water passing through the pipes, ensuring fair pricing, reasonable water use, and effective water resource management.

[0003] Existing water meters, due to fluctuations in water pressure or slight backflow in the pipeline, will rotate on their own when water is not in use, especially in high-rise buildings or long-distance water supply systems, resulting in errors in water metering and waste of water resources. Summary of the Invention

[0004] The purpose of this invention is to provide a water meter that prevents self-rotation and dripping, which has the advantages of preventing the water meter from rotating and dripping.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A self-rotating and drip-proof water meter is provided, including a casing. A rotating shaft is disposed inside the casing. Multiple blades are fixedly connected to the outer wall of the rotating shaft. Multiple spring grooves are formed on the outer walls of both ends of the rotating shaft. Locking springs are fixedly connected to the inner walls of the multiple spring grooves. A locking block is fixedly connected to the other end of each locking spring. Ratchet grooves are formed on both sides of the inner wall of the casing. The two ends of the rotating shaft are located inside two of the ratchet grooves. The end of the locking block furthest from the spring groove is located inside the ratchet groove, and the end of the locking block furthest from the spring groove is triangular. Optionally, a water outlet pipe is fixedly connected to the outer wall of the casing, a fixing ring is fixedly connected to the inner wall of the water outlet pipe, a check spring is fixedly connected to the outer wall of the fixing ring, a moving plate is fixedly connected to one end of the check spring, a connecting rod is fixedly connected to the outer wall of the moving plate, and a sealing plate is fixedly connected to the other end of the connecting rod.

[0006] Optionally, the inner wall of the casing is provided with a limiting groove, and the number of limiting grooves is multiple. The outer wall of the movable plate is fixedly connected with a limiting block, and the number of limiting blocks is multiple. The multiple limiting blocks are respectively located inside the multiple limiting grooves.

[0007] Optionally, the movable plate has a through groove inside, and there are multiple through grooves. The diameter of the connecting rod is smaller than the inner diameter of the fixed ring.

[0008] Optionally, a water inlet pipe is fixedly connected to the outer wall of the watch case, and a connector is threadedly connected to the outer wall of the water outlet end of the water outlet pipe and the outer wall of the water inlet end of the water inlet pipe. A connecting groove is opened at both ends of the connector, and the water outlet pipe and the water inlet pipe are threadedly connected in the connecting groove at the corresponding position.

[0009] Optionally, a sealing ring is fixedly installed inside the connecting groove, and the ends of the water outlet pipe and the water inlet pipe are fitted with the sealing ring at the corresponding positions.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model has multiple spring grooves on the outer walls of both ends of the rotating shaft. Locking blocks are set inside the spring grooves, and locking springs are used to restrict the end of the locking block near the spring groove to the inside of the blade. When the water is not flowing, the triangular end of the locking block is inserted into the ratchet groove. When the water flows, the water enters the inside of the meter casing from the water inlet pipe and impacts the bottommost blade, causing the rotating shaft and multiple blades to rotate clockwise. When the rotating shaft rotates clockwise, multiple locking blocks rotate synchronously with the rotating shaft. During this process, the locking block first moves into the spring groove and disengages from the first ratchet groove. At this time, the locking spring is in a compressed state. After the locking block moves to the next ratchet groove, the locking spring rebounds, causing the locking block to enter the next ratchet groove. This allows the rotating shaft to rotate only clockwise, preventing the water meter from rotating when the water is not flowing due to water pressure fluctuations or slight backflow in the pipe.

[0011] 2. This utility model has a fixing ring inside the water outlet pipe. When water flows out from inside the casing through the water outlet pipe, the water flows through the middle of the fixing ring and pushes the sealing plate to the left. At this time, the anti-reverse spring is in a compressed state. After the water flow stops, the anti-reverse spring rebounds, causing the moving plate to return to its original position, and finally the sealing plate is tightly fitted with the fixing ring again to prevent water backflow. Both the water outlet pipe and the water inlet pipe have threaded connectors at their ends. The two connecting grooves inside the connectors are equipped with sealing rings. The connectors are connected to the ends of the water outlet pipe and the water inlet pipe by screwing, and finally the ends of the water outlet pipe and the water inlet pipe are tightly pressed against the sealing rings to achieve a sealing effect and prevent leakage.

[0019] Reference Figure 1-7 This invention provides a description of an anti-rotation and anti-drip water meter according to an embodiment of the present invention. The anti-rotation and anti-drip water meter includes a housing 1. A rotating shaft 2 is disposed inside the housing 1. Multiple blades 3 are fixedly connected to the outer wall of the rotating shaft 2. Multiple spring grooves 4 are formed on the outer walls of both ends of the rotating shaft 2. Locking springs 5 ​​are fixedly connected to the inner walls of the multiple spring grooves 4. A locking block 6 is fixedly connected to the other end of each locking spring 5. Ratchet grooves 7 are formed on both sides of the inner wall of the housing 1. The two ends of the rotating shaft 2 are located inside two ratchet grooves 7, respectively. The end of the locking block 6 furthest from the spring groove 4 is located inside the ratchet groove 7. The end of block 6 furthest from spring groove 4 is triangular. A water outlet pipe 8 is fixedly connected to the outer wall of the casing 1. A fixing ring 9 is fixedly connected to the inner wall of the water outlet pipe 8. A check spring 10 is fixedly connected to the outer wall of the fixing ring 9. A moving plate 11 is fixedly connected to one end of the check spring 10. A connecting rod 12 is fixedly connected to the outer wall of the moving plate 11. A sealing plate 13 is fixedly connected to the other end of the connecting rod 12. Multiple spring grooves 4 are opened on the outer walls of both ends of the rotating shaft 2. A locking block 6 is set inside the spring groove 4, and a locking spring 5 is used to restrict the end of the locking block 6 near the spring groove 4 to the blade 3. When the water is not flowing, the triangular end of the locking block 6 is inserted into the ratchet groove 7. When the water flows, the water enters the interior of the watch case 1 from the water inlet pipe 17 and impacts the bottommost blade 3, causing the rotating shaft 2 and multiple blades 3 to rotate clockwise. When the rotating shaft 2 rotates clockwise, multiple locking blocks 6 rotate synchronously with the rotating shaft 2. During this process, the locking block 6 first moves into the spring groove 4, disengaging from the first ratchet groove 7. At this time, the locking spring 5 is in a compressed state. After the locking block 6 moves to the next ratchet groove 7, the locking spring 5 rebounds, causing the locking block 6 to enter the next ratchet groove 7. The water meter is inserted into the next ratchet groove 7, so that the rotating shaft 2 can only rotate clockwise. This prevents the water meter from rotating when the water is not flowing due to fluctuations in water pressure or slight backflow in the pipe. A fixing ring 9 is set inside the water outlet pipe 8. When the water flows out from the inside of the meter casing 1 through the water outlet pipe 8, the water flows through the middle of the fixing ring 9 and pushes the sealing plate 13 to the left. At this time, the anti-reverse spring 10 is in a compressed state. After the water flow stops, the anti-reverse spring 10 rebounds, causing the moving plate 11 to reset. Finally, the sealing plate 13 is tightly fitted with the fixing ring 9 again to prevent the water from flowing back.

[0020] In another embodiment of this utility model, please refer to Figure 2 The inner wall of the casing 1 has a limiting groove 14, and there are multiple limiting grooves 14. The outer wall of the moving plate 11 is fixedly connected to a limiting block 15, and there are multiple limiting blocks 15. The multiple limiting blocks 15 are located inside the multiple limiting grooves 14, which improves the stability of the moving plate 11 when it moves. The inside of the moving plate 11 has a through groove 16, and there are multiple through grooves 16. The diameter of the connecting rod 12 is smaller than the inner diameter of the fixed ring 9, so that when the sealing plate 13 moves to the left, the water can flow out through the multiple through grooves 16 and the inside of the fixed ring 9 through the water outlet pipe 8.

[0021] In another embodiment of this utility model, please refer to Figures 1 to 3 The outer wall of the casing 1 is fixedly connected to a water inlet pipe 17. The outer wall of the water outlet pipe 8 and the outer wall of the water inlet pipe 17 are both threadedly connected to a connector 18. Both ends of the connector 18 are provided with connecting grooves 19. The water outlet pipe 8 and the water inlet pipe 17 are threadedly connected to the corresponding connecting grooves 19. A sealing ring 20 is fixedly installed inside the connecting groove 19. The ends of the water outlet pipe 8 and the water inlet pipe 17 fit with the corresponding sealing rings 20. The connector 18 is threadedly connected to the ends of the water outlet pipe 8 and the water inlet pipe 17. The two connecting grooves 19 inside the connector 18 are provided with sealing rings 20. The connector 18 is connected to the ends of the water outlet pipe 8 and the water inlet pipe 17 by screwing. Finally, the ends of the water outlet pipe 8 and the water inlet pipe 17 are pressed tightly against the sealing rings 20 to achieve a seal and prevent leakage.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
