Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0033] In some embodiments, please refer to the accompanying drawings of the specification. Figures 1-6 , a sealed moisture-proof intelligent water meter, comprising a box 1,

[0034] The upper end of the box body 1 is hinged with a baffle, which is made of transparent acrylic material. It can not only block dust for the water meter body 2 and ensure a sealed environment, but also make it convenient for users to check the water level of the water meter body 2.

[0035] The inner wall of the box body 1 is made of moisture-proof material;

[0036] A water meter body 2 is fixedly installed inside the box 1; the left end of the water meter body 2 is the water inlet, and the right end of the water meter body 2 is the water outlet;

[0037] The left and right ends of the water meter body 2 are equipped with quick disassembly and assembly mechanisms 3 for conveniently connecting the water meter body 2 to the water inlet pipe 6 and the water outlet pipe 7;

[0038] The quick disassembly and assembly mechanism 3 includes a pressurized rotary positioning assembly 31 for rapid positioning for disassembly and assembly, and a self-locking assembly 32 for maintaining the connection between the water meter body 2 and the water inlet pipe 6 and the water outlet pipe 7.

[0039] The front end of the box 1 is fixedly mounted with a central control box 5;

[0040] The quick disassembly and assembly mechanism 3 is equipped with an automatic water leakage alarm mechanism 4; when water leakage occurs at the connection of the water meter body 2, the automatic water leakage alarm mechanism 4 can remind the user;

[0041] The automatic water leakage alarm mechanism 4 is connected to the central control box 5;

[0042] In the present invention, after the installer aligns the water meter body 2 with the water inlet pipe 6 and the water outlet pipe 7 by means of the pressurized rotary positioning assembly 31, the water meter body 2 is locked and fixed to the water inlet pipe 6 and the water outlet pipe 7 by means of the self-locking assembly 32. In addition, the sealing effect of the water meter body 2 is further enhanced by the sealing ring provided in the pressurized rotary positioning assembly 31. After the installation is completed, the automatic water leakage alarm mechanism 4 can monitor the tightness of the connection of the water meter body 2 at any time. If a water leakage occurs, the automatic water leakage alarm mechanism 4 can quickly send a signal to the central control box 5, and issue a water leakage warning to the user through the central control box 5, thereby improving the practicality of the water meter.

[0043] The pressurized rotation positioning assembly 31 includes a first snap ring 311, a second snap ring 312, a T-shaped block 313, a positioning inclined groove 314, a positioning block 315 and a pressurized inclined surface 316. The first snap ring 311 is symmetrically fixedly installed at the left and right ends below the water meter body 2; the two second snap rings 312 are fixedly installed at the right end of the water inlet pipe 6 and the left end of the water outlet pipe 7; the outer ends of the first snap ring 311 and the second snap ring 312 are symmetrically fixedly installed with T-shaped blocks 313 on both sides. Positioning blocks 315 are symmetrically fixedly installed on the front and rear sides of the outer ends of the first and second retaining rings 311 and 312. A positioning bevel 314 is provided in the middle of the T-shaped block 313. The positioning bevel 314 is in the shape of a T-shape that gradually narrows from wide. A sealing ring is fixedly installed in each of the first and second retaining rings 311 and 312. A pressurizing inclined surface 316 is provided on the positioning block 315 to cooperate with the positioning bevel 314. The positioning block 315 and the positioning bevel 314 are in limited sliding connection.

[0044] The self-locking assembly 32 includes a locking pin 321, a locking groove 322, a fixing block 323 and a compression spring 324. The fixing block 323 is fixedly installed at the opposite ends of the two T-shaped blocks 313 on the first snap ring 311. One end of the compression spring 324 is fixedly connected to the inside of the fixing block 323, and the other end of the compression spring 324 is fixedly connected to one end of the locking pin 321. A sliding groove 325 is provided in the middle of the first snap ring 311, and the locking pin 321 is limitedly slidably connected to the sliding groove 325. A locking groove 322 is provided in the middle of the two positioning blocks 315 on the second snap ring 312. The locking pin 321 is plugged into the locking groove 322.

[0045] When the water meter is in a closed position, the water inlet pipe 6 with the second clamping ring 312 is moved closer to the first clamping ring 311 at the left end of the water meter body 2. At this time, the T-shaped block 313 on the second clamping ring 312 is misaligned with the T-shaped block 313 on the first clamping ring 311 until the right end of the second clamping ring 312 touches the left end of the first clamping ring 311. The second clamping ring 312 is then rotated so that the positioning block 315 on the second clamping ring 312 rotates toward the T-shaped block 313 on the first clamping ring 311, and the T-shaped block 313 on the second clamping ring 312 rotates toward the positioning block 315 on the first clamping ring 311. When the positioning block 315 on the second clamping ring 312 rotates to the position of the positioning bevel 314 on the first clamping ring 311, the positioning bevel 314 will compress the pressurizing inclined surface 316 inwardly, and the compressed pressurizing inclined surface 316 will apply elastic force outward to make the positioning bevel 314 and the positioning block 315 move toward each other. When the cam 321 is in the closed position, the locking pin 321 is pressed against the locking groove 322, and the locking pin 321 is pressed against the locking groove 322. When the cam 321 is in the closed position, the locking pin 321 is pressed against the locking groove 322, and the locking pin 321 is pressed against the locking groove 322.

[0046] The automatic water leakage alarm mechanism 4 includes a test paper 41 and a color sensor 42. The two test papers 41 are bonded to the first clamp ring 311 and the second clamp ring 312. The color sensor 42 is symmetrically fixedly mounted on the bottom end of the box 1. The test paper 41 is cobaltous chloride test paper. The color sensor 42 is electrically connected to the central control box 5.

[0047] In the present utility model, after the connection between the water meter body 2 and the water inlet pipe 6 and the water outlet pipe 7 is completed, two test papers 41 are pasted at the connection between the first clamp ring 311 and the second clamp ring 312; the test paper 41 is blue in a dry state. If a water leak occurs at the connection, the test paper 41 changes from blue to purple and finally to pink. The set color detected by the color sensor 42 is pink. When the color sensor 42 detects that the color of the test paper 41 changes to pink, a signal will be generated to the central control box 5, and the central control box 5 will notify the user of the water leak. At this time, the user can check the leaking part in time, thereby improving the practicality of the smart water meter.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
