Description

Technical Field

[0001] This utility model belongs to the field of water meter technology, and in particular relates to an Internet of Things (IoT) water meter. Background Technology

[0002] An IoT water meter is a smart water meter based on Internet of Things (IoT) technology. It transmits water usage data in real time through wireless communication technologies (such as NB-IoT, LoRa, 4G / 5G, etc.) to achieve remote monitoring, data analysis, and automated management. Although users can remotely monitor water usage data during use, maintenance personnel need to conduct on-site inspections of the IoT water meter during maintenance, such as meter calibration, communication fault diagnosis, and power supply maintenance.

[0003] Currently, most IoT water meters adopt a fixed structure, and the meter head cannot rotate. This makes it difficult for maintenance personnel to directly observe the meter data when the installation location is limited (such as a corner or narrow space). To address this, an IoT water meter with a rotatable meter head, as disclosed in application number CN2024212486128, includes an IoT water meter assembly. The assembly includes an IoT water meter head, a water inlet pipe communicating with the meter head, a hexagonal bolt fixed to the outer wall of the water inlet pipe, and a water supply pipe located on the side of the water inlet pipe. A rotating sealing assembly includes an internal thread within the water supply pipe, an external threaded pipe communicating with the water inlet pipe, a sealing sleeve fitted with the external threaded pipe, a rubber sleeve fitted with the water supply pipe, and an annular sealing groove on the inner side of the sealing sleeve. This technical solution allows for tilt adjustment of the entire IoT water meter head, so that even in corners where the readings cannot be directly observed, the display area of ​​the meter head can be directly aligned with the user for convenient observation and use.

[0004] However, the above technical solution still has some drawbacks: 1. After rotating the meter head, the internal and external threads are prone to loosening, making it difficult to guarantee a good waterproof seal; 2. The rubber sleeve is exposed, making it prone to aging and cracking, resulting in a short service life. Therefore, there is still room for improvement. Utility Model Content

[0008] Preferably, the inner wall of the sleeve protrudes inward to form an annular inner boss, one end of the inner boss is fixedly connected to the connecting plate, the other end of the inner boss is spaced apart from the limiting ring, and the inner boss abuts against the outer side of the first waterproof sealing ring.

[0009] Preferably, the inner ring of the inner boss is provided with a plurality of first protruding rings, which are distributed at intervals along the axial direction of the sleeve.

[0010] Preferably, the annular cover plate is formed by splicing two arc-shaped plates. One end of the arc-shaped plate is provided with a groove, and the other end of the arc-shaped plate is provided with a locking block that cooperates with the groove. The outer convex arc surface of the arc-shaped plate is provided with a screw hole, and the outer side surface of the sleeve is provided with a through hole that corresponds to the two screw holes one by one.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] Example 1: As Figures 1 to 4 As shown, an IoT water meter includes a meter body 1 and two water pipes 2. The meter body 1 has two connectors 11 corresponding to the two water pipes 2. The connectors 11 are threadedly connected to the corresponding water pipes 2. A waterproof sealing assembly 3 is provided between the connectors 11 and the corresponding water pipes 2. The waterproof sealing assembly 3 includes a sleeve 31, an annular cover plate 32, and a limiting ring 33. One end of the sleeve 31 protrudes inward to form an annular connecting plate 311, which is fitted onto the outside of the connector 11 and fixedly connected to the outer side of the connector 11. The other end of the sleeve 31 extends to the outside of the water pipe 2. The annular cover plate 32 covers the other end of the sleeve 31 between the sleeve 31 and the water pipe 2. The limiting ring 33 is fixedly disposed on the outside of the water pipe 2 and located inside the sleeve 31. The limiting ring 33 divides the inside of the sleeve 31 into two chambers, each containing a waterproof sealing ring 34. The water pipes 2 have internal threads, and the connectors 11 have external threads on the outside. The connectors 11 are threadedly connected to the corresponding water pipes 2. It should be noted that there is a gap between the outer ring of the limiting ring 33 and the inner wall of the sleeve 31.

[0027] In this embodiment, the chamber near one end of the sleeve 31 is defined as the first chamber 312, and the waterproof sealing ring 34 in the first chamber 312 is defined as the first waterproof sealing ring 341. The two ends of the first waterproof sealing ring 341 abut against the connecting plate 311 and the limiting ring 33, respectively. The chamber near the other end of the sleeve 31 is defined as the second chamber 313, and the waterproof sealing ring 34 in the second chamber 313 is defined as the second waterproof sealing ring 342. The two ends of the second waterproof sealing ring 342 abut against the limiting ring 33 and the annular cover plate 32, respectively.

[0028] When the maintenance personnel rotate the meter head body 1, the meter head body 1 moves closer to or further away from the water pipe 2 by a small distance. At this time, the limiting ring 33 will squeeze the first waterproof sealing ring 341 or the second waterproof sealing ring 342 inside the sleeve 31 to ensure that a waterproof sealing ring 34 maintains a good sealing effect, thereby ensuring the sealing performance.

[0029] Example 2: Figure 3 and Figure 4As shown, the rest of the components are the same as in Embodiment 1, except that the inner wall of the sleeve 31 protrudes inward to form an annular inner boss 314. One end of the inner boss 314 is fixedly connected to the connecting plate 311, and the other end of the inner boss 314 is spaced apart from the limiting ring 33. The inner boss 314 abuts against the outer side of the first waterproof sealing ring 341. The inner boss 314 can restrict the position of the first waterproof sealing ring 341, optimize the sealing pressure distribution, and also improve the structural strength of the sleeve 31. The end face of the water pipe 2 is located between the other end of the inner boss 314 and the connecting plate 311 to ensure that the inner boss 314 and the water pipe 2 cooperate to press the first waterproof sealing ring 341 tightly.

[0030] In this embodiment, the inner ring of the inner boss 314 is provided with a plurality of first protruding rings 3141. The plurality of first protruding rings 3141 are distributed at intervals along the axial direction of the sleeve 31, which helps to improve the waterproof sealing performance of the contact surface between the first waterproof sealing ring 341 and the inner boss 314.

[0031] Example 3: Figure 2 , Figure 3 and Figure 5 As shown, the rest of the parts are the same as in Embodiment 1, except that the annular cover plate 32 is formed by splicing two arc-shaped plates 321. One end of the arc-shaped plate 321 is provided with a groove 3211, and the other end of the arc-shaped plate 321 is provided with a locking block 3212 that mates with the groove 3211. The outer convex arc surface of the arc-shaped plate 321 is provided with a screw hole 3213, and the outer side surface of the sleeve 31 is provided with a through hole 315 that corresponds one-to-one with the two screw holes 3213. The bolt 4 passes through the through hole 315 and is threaded into the corresponding screw hole 3213. In this embodiment, the locking block 3212 of one arc-shaped plate 321 engages with the groove 3211 of the other arc-shaped plate 321.

[0032] In this embodiment, an arc-shaped protrusion 3214 is provided on the side of the arc plate 321 facing the limiting ring 33. The protrusions 3214 on the two arc plates 321 are spliced ​​to form a second protruding ring, which helps to improve the waterproof sealing performance of the contact surface between the second waterproof sealing ring 342 and the arc plate 321.

[0033] Example 4: Figure 2 , Figure 4 and Figure 5 As shown, the rest of the parts are the same as in Embodiment 3. The difference is that the outer convex arc surface of the arc plate 321 protrudes outward to form a lug 323. The lug 323 rests on the other end of the sleeve 31. A waterproof sealing gasket 5 is provided between the lug 323 and the other end of the sleeve 31, which helps to improve the local waterproof sealing.

[0034] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
