Description

Technical Field

[0001] The utility model relates to the technical field of intelligent water meters, in particular to a high-precision intelligent water meter sensor. Background Technique

[0002] In an intelligent water meter system, as a key component, the sensor is responsible for real-time monitoring and transmitting water flow data. Its accuracy and stability are directly related to the efficiency and accuracy of water resource management. However, with the popularization and complexity of the intelligent water network system, the requirements for the sensor and its connection method with the external system are also increasing day by day.

[0003] When the existing intelligent water meter sensors are connected to an external data acquisition or control system, a simple plug-and-play interface is mostly used. Although this design is convenient for installation and replacement, there are problems of unstable connection and easy loosening. Especially under long-term vibration or external force, it may cause data transmission interruption or distortion, affecting the continuity and accuracy of data collection. In addition, the working environment of the water meter sensor is often in a humid or water-rich environment, which poses strict requirements on the waterproof performance of the sensor. Traditional plug interfaces are often difficult to effectively isolate water penetration. Once water invades the interior of the sensor, it may not only damage electronic components but also cause safety problems such as short circuits, seriously threatening the stable operation of the entire intelligent water network system.

[0027] Embodiment 1:

[0028] Referring to Figures 1 - 6 , a high-precision intelligent water meter sensor includes a chip 1, an integrated wire harness 2, and a plug 3, and further includes: the chip 1 and the plug 3 are electrically connected through the integrated wire harness 2; side grooves 7 are provided on both sides of the plug 3, an arc-shaped locking member 4 is provided in the side grooves 7, and a protruding part 402 is provided on the arc-shaped locking member 4; surface fixing plates 6 are provided on both the upper and lower surfaces of the plug 3, and second anti-slip grooves 601 are provided on the surface fixing plates 6.

[0029] In the present utility model, when in use, the user presses the arc-shaped locking member 4 by hand, causing the arc-shaped locking member 4 to contract into the side groove 7, and the protruding portion 402 also retracts into the side groove 7. At this time, the surface fixing plate 6 is also flush with the surface of the plug 3. At this time, the plug 3 can be inserted into the interface of an external device. Then, the arc-shaped locking member 4 is released, and both the arc-shaped locking member 4 and the surface fixing plate 6 will automatically pop out. The upper and lower surface fixing plates 6 abut against the upper and lower surfaces of the external device interface, and the protruding portions 402 on the arc-shaped locking member 4 abut against the left and right sides of the external device interface, thereby more conveniently and stably fixing the plug 3.

[0030] Embodiment 2:

[0031] Referring to Figures 1 - 6 , which is basically the same as Embodiment 1. Furthermore: A first anti-slip groove 401 is provided in the part of the arc-shaped locking member 4 extending outside the side groove 7; A positioning plate 5 is provided in the part of the integrated wire harness 2 close to the plug 3. The integrated wire harness 2 passes through the positioning plate 5. Limiting holes 501 are provided at both ends of the positioning plate 5. A limiting rod 403 is fixedly connected to the part of the arc-shaped locking member 4 extending outside the side groove 7, and the limiting rod 403 is inserted into the limiting hole 501; A first plug rod 8 is fixedly connected to the surface of the arc-shaped locking member 4 facing the side groove 7; An inner built-in groove 9 is provided in the plug 3, and the first plug rod 8 is inserted into the inner built-in groove 9. A piston plate 10 is fixedly connected to the part of the first plug rod 8 placed in the inner built-in groove 9, and an elastic component 11 is provided between the piston plate 10 and the inner built-in groove 9; An inner built-in groove 14 is provided in the plug 3, and the inner built-in groove 9 and the inner built-in groove 14 are connected by an air pipe 12; A second plug rod 13 is fixedly connected to the surface fixing plate 6, and the second plug rod 13 is inserted into the inner built-in groove 14. A piston plate 15 is fixedly connected to one end of the second plug rod 13 placed in the inner built-in groove 14, and an elastic component 16 is provided between the piston plate 15 and the inner built-in groove 14; There are two arc-shaped locking members 4.

[0032] When pressing the arc-shaped locking member 4 by hand to cause the arc-shaped locking member 4 to contract into the side groove 7, the first plug rod 8 pushes the piston plate 10 to move inward into the inner built-in groove 9. At the same time, the piston plate 10 compresses the elastic component 11. At this time, the piston plate 10 also extracts the air in the inner built-in groove 14 through the air pipe 12, pulling the surface fixing plate 6 into the plug 3 (i.e., the slot for placing the surface fixing plate 6). At this time, the elastic component 16 is in a compressed state;

[0033] When the plug 3 is inserted into the interface of an external device and the arc-shaped locking member 4 is released, the elastic component 11 and the elastic component 16 reset, respectively pushing out the arc-shaped locking member 4 and the surface fixing plate 6. The upper and lower surface fixing plates 6 abut against the upper and lower surfaces of the external device interface, and the protruding portions 402 on the arc-shaped locking member 4 abut against the left and right sides of the external device interface, thereby more conveniently and stably fixing the plug 3;

[0034] The convex portions 402 and the anti-slip grooves II 601 on the surface fixing plate 6 are both made of rubber material. The multiple convex portions 402 and the anti-slip grooves II 601 can all form an overflow water groove, which can prevent external moisture from penetrating into the external connection device, thereby ensuring the stable operation of the entire intelligent water network system.

[0035] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
