[0002] A pulse NB water meter typically refers to a water meter that uses narrowband Internet of Things (IoT) technology. This water meter has a pulse output function and can upload water consumption data to the cloud or management platform in real time or periodically.

[0003] Typically, due to the different lifespans and maintenance requirements of the pulse communication section and the mechanical water meter section, the mechanical water meter section can usually still operate normally after many years of use, while the pulse communication section is more prone to failure. Currently, most pulse water meters require the entire water meter to be replaced or disassembled even if only the pulse communication section fails, which increases the difficulty and cost of maintenance. Utility Model Content

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a detachable pulse NB water meter, including a frame 1, a fixing plate 2 fixedly connected to the outer wall of the frame 1, a fixing column 3 fixedly connected to the lower surface of the fixing plate 2, a retaining ring 4 fixedly connected to the bottom end of the fixing column 3, a fixing frame 5 provided between the retaining ring 4 and the outer wall of the frame 1, sleeves 6 fixedly connected to the inner sides of the fixing frame 5, a sliding column 7 slidably connected to the inner wall of the sleeve 6, a push button 8 fixedly connected to one end of the sliding column 7, a locking block 9 fixedly connected to the other end of the sliding column 7, the lower surface of the locking block 9 being provided on the upper surface of the retaining ring 4, a spring 10 provided on the outer wall of the sliding column 7, one end of the spring 10 fixedly connected to the outer wall of the sleeve 6, the other end of the spring 10 fixedly connected to the outer wall of the locking block 9, and a measuring component provided on the outer wall of the fixing frame 5, the measuring component being used to measure water flow rate;

[0024] Specifically, the frame 1 and the fixing plate 2 are equipped with pulse communication modules. The frame 1 can provide fixed support for the fixing plate 2, and the fixing plate 2 can also provide fixed support for the fixing column 3. The fixing column 3 can in turn provide fixed support for the retaining ring 4. When the fixing column 3 is placed into the inner wall of the fixing frame 5, the spring force of the spring 10 drives the retaining block 9 to limit the retaining ring 4, thus achieving the fixed effect. When disassembly is required, the push button 8 is pulled, which drives the sliding column 7 to slide on the inner wall of the sleeve 6. When the sliding column 7 slides, it also drives the retaining block 9 to slide, releasing the limit on the retaining ring 4, thus achieving the function of quickly disassembling the frame 1. The mechanical parts of the water meter are usually more durable and have a longer lifespan, while the pulse communication part is more prone to problems. By quickly separating the two parts, the individual maintenance and replacement of the communication module significantly reduces the long-term maintenance cost and repair time of the entire device.

[0025] Reference Figure 1 The measuring component includes a water meter body 11, the outer wall of the fixing frame 5 is fixedly connected to the outer wall of the water meter body 11, and a water pipe 12 is fixedly connected inside the water meter body 11.

[0026] Specifically, the water meter body 11 can measure the water flow inside the water pipe 12, read the water meter data through the non-magnetic sensor inside the fixing plate 2, and transmit it to the metering communication module inside the frame 1 to finally obtain the water meter reading.

[0027] Reference Figure 3 The inner wall of frame 1 is provided with a battery compartment 13, and a sliding column 14 is slidably connected to the inner wall of battery compartment 13. A push button 15 is fixedly connected to one end of sliding column 14, and a U-shaped plate 16 is fixedly connected to the other end of sliding column 14. The U-shaped plate 16 is slidably connected to the inner wall of battery compartment 13. A rotating column 17 is rotatably connected inside the U-shaped plate 16, and a sliding plate 18 is slidably connected to the outer wall of rotating column 17. The outer wall of sliding plate 18 is slidably connected to the inner wall of battery compartment 13. A groove 19 is opened inside the sliding plate 18, and the outer wall of rotating column 17 is slidably connected to the inner wall of groove 19. A connecting column 20 is fixedly connected to the outer wall of sliding plate 18, and a locking column 21 is fixedly connected to the outer wall of connecting column 20. The outer wall of locking column 21 is provided on the inner wall of frame 1. A spring 22 is provided on the outer wall of connecting column 20. One end of spring 22 is fixedly connected to the inner wall of battery compartment 13, and the other end of spring 22 is fixedly connected to the outer wall of locking column 21.

[0028] Specifically, the sliding post 14 can provide fixed support for the push button 15. When the push button 15 is pushed, the push button 15 will cause the sliding post 14 to slide. The sliding of the sliding post 14 will cause the U-shaped plate 16 to slide. The U-shaped plate 16 can also support the rotating post 17 and cause the rotating post 17 to slide on the inner wall of the groove 19. At the same time, the sliding of the rotating post 17 will cause the sliding plate 18 to slide. The sliding of the sliding plate 18 will cause the connecting post 20 to slide. The sliding of the connecting post 20 will cause the locking post 21 to slide. When the locking post 21 slides from the inner wall of the frame 1 to the inner wall of the battery compartment 13, the limitation on the battery compartment 13 is released. Then, the battery compartment 13 can be quickly disassembled by pulling out the handle.

[0029] Working principle: When the device is needed, the operator first pulls push button 8, causing push button 8 to move sliding column 7 along the inner wall of sleeve 6. The sliding of sliding column 7 will cause the locking block 9 to slide and compress spring 10. The sliding of locking block 9 will release the limiting position of locking ring 4, thereby achieving the effect of quick disassembly of frame 1, making it convenient for maintenance of pulse communication module. When the pulse module is out of power and the battery needs to be replaced, first pull push button 15, causing push button 15 to move sliding column 14, thereby moving U-shaped plate 16, which in turn moves rotating column 17. The rotating column 17 slides along the inner wall of the groove 19, which in turn drives the sliding plate 18 to slide. The sliding plate 18 also drives the connecting column 20 to slide, thereby causing the locking column 21 to slide from the inner wall of the frame 1 to the inner wall of the battery compartment 13, releasing the limit and achieving the function of quickly disassembling the battery compartment 13. That is, this device can not only make the pulse communication module individually maintained or replaced by quickly disassembling the frame 1, reducing maintenance time and maintenance costs, but also allow the battery to be replaced directly without disassembling other parts by opening the disassembly battery compartment 13, reducing equipment downtime.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
