DETAILED DESCRIPTION

[0040] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0041] Embodiment 1:

[0042] like Figure 1-Figure 8 As shown, the anti-leakage detection device for the smart water meter of this embodiment includes a detection water pipe 201, one end of the detection water pipe 201 is fixedly provided with a joint 202, the joint 202 is used in conjunction with the water inlet 101 provided on the water meter body 100, a water outlet 102 is fixedly provided on the side of the water meter body 100 away from the water inlet 101, a first shell 203 is fixedly provided on the joint 202, and a second shell 204 is covered on the water inlet 101, and the second shell 204 is connected to the side of the water meter body 100. Fixedly connected, the first shell 203 is used together with the second shell 204, a detection cover 205 is provided on the water outlet 102, and detection parts are connected to the second shell 204 and the detection cover 205, and a sealing mechanism 300 is provided in the first shell 203 and the second shell 204 for improving the sealing performance when the joint 202 is connected to the water inlet 101 to prevent water leakage during detection, and a locking mechanism 400 is provided on the second shell 204 for fixing the joint 202 to prevent the joint 202 from falling off during detection.

[0043] The anti-leakage detection device for the intelligent water meter realizes leakage detection of the water inlet 101 and the water outlet 102 of the water meter body 100 by designing specific structures and components. One end of the detection water pipe 201 is connected to the water inlet 101 of the water meter body 100 through the joint 202, and the other end covers the water outlet 102 through the detection cover 205. During detection, the detection water pipe 201 is connected to the water inlet 101 through the joint 202, and the locking mechanism 400 is locked to fix the joint 202 in the water inlet 101, and then the liquid is transported through the detection water pipe 201. The sealing mechanism 300 seals the joint 202 and the water inlet 101, and whether the water meter body 100 is leaking is checked by the condition of the detection part. The sealing mechanism 300 effectively prevents the leakage problem during the detection process and ensures the accuracy of the detection result. The locking mechanism 400 ensures that the joint 202 will not fall off during the detection process, thereby enhancing the structural stability of the entire detection device.

[0044] like Figure 1-Figure 3 As shown, the detection component includes a connecting tube 206, two connecting tubes 206 are provided and correspond one to one with the second shell 204 and the detection cover 205, one end of the connecting tube 206 is fixedly connected with the second shell 204 and the detection cover 205 respectively, and the other end of the connecting tube 206 is fixedly connected with the detection box 207, and anhydrous copper sulfate powder for detection is placed in the detection box 207.

[0045] When the water meter body 100 leaks, water will flow into the detection box 207 through the connecting pipe 206 and react with the anhydrous copper sulfate powder. The anhydrous copper sulfate powder will turn blue, thereby confirming that the water meter body 100 is leaking. The anhydrous copper sulfate powder is very sensitive to moisture and can react quickly, thereby improving the sensitivity of detection.

[0046] like Figure 3-Figure 5 As shown, the sealing mechanism 300 includes a fixing ring 301, a rubber pad 303, a guide head 304 and a fixing rod 305. The fixing ring 301 is fixedly arranged on the first shell 203 and is coaxially arranged with the first shell 203. The guide head 304 is fixedly arranged on the side of the second shell 204 and close to the side of the first shell 203. There are multiple guide heads 304 distributed equidistantly along the circumference of the second shell 204. The first shell 203 is provided with fixing holes 302 for limiting the guide heads 304. The number of fixing holes 302 is the same as that of the guide heads 304 and corresponds one to one. The number of fixing rods 305 is the same as that of the guide heads 304 and corresponds one to one. The fixing rod 305 is rotatably arranged on one side of the guide head 304 close to the fixing hole 302. The rubber pad 303 is arranged on the fixing ring 301 and is coaxially arranged with the fixing hole 302. The number of rubber pads 303 is the same as that of the fixing holes 302 and corresponds one to one.

[0047] The sealing mechanism 300 achieves a tight seal between the joint 202 and the water inlet 101 through the cooperation of the fixing ring 301, the rubber pad 303, the guide head 304 and the fixing rod 305. When the joint 202 is docked with the water inlet 101, the guide head 304 enters the fixing hole 302 and simultaneously rotates the fixing rod 305 and presses the rubber pad 303, thereby achieving sealing. The elasticity of the rubber pad 303 and the pressing effect of the guide head 304 ensure the sealing between the joint 202 and the water inlet 101, thereby preventing water leakage.

[0048] like Figure 7 As shown, the locking mechanism 400 includes a locking ring 401, a fixed block 402, an insertion rod 403 and an eccentric wheel 404. The locking ring 401 is fixedly arranged on the second shell 204 and is coaxially arranged with the second shell 204. Two fixed blocks 402 are provided. The two fixed blocks 402 are respectively fixedly arranged at two ends of the locking ring 401 close to each other. One end of the insertion rod 403 is fixedly passed through one of the fixed blocks 402 and extends outward and moves to pass through the other fixed block 402. The eccentric wheel 404 is rotatably arranged at one end of the insertion rod 403 that passes through the fixed block 402, and the eccentric wheel 404 is arranged parallel to the insertion rod 403.

[0049] When the joint 202 is docked with the water inlet 101, the eccentric wheel 404 is rotated so that the thick edge of the eccentric wheel 404 contacts the side wall of the fixed block 402, so that the inserted rod 403 drives the fixed block 402 to move closer to the middle, so that the two fixed blocks 402 are close to each other, thereby locking the joint 202, effectively preventing the joint 202 from falling off during the detection process, and enhancing the structural stability of the entire detection device.

[0050] like Figure 6-Figure 8 As shown, the sealing mechanism 300 further includes a sealing ring 306 and a mounting groove 308 . The mounting groove 308 is provided in the first housing 203 . The mounting groove 308 cooperates with the second housing 204 . The sealing ring 306 is fixed in the mounting groove 308 .

[0051] A sealing ring 306 is arranged in the installation groove 308. When the joint 202 is connected to the water inlet 101, the sealing ring 306 achieves a tighter sealing effect, thereby improving the sealing between the joint 202 and the water inlet 101 and preventing water leakage.

[0052] like Figure 7 As shown, a rotating handle 405 is fixedly provided on the eccentric wheel 404. The design of the rotating handle 405 allows the user to lock or unlock the device through a simple rotation action, thereby improving the convenience of operation.

[0053] Embodiment 2:

[0054] Compared with Example 1, Figure 2-Figure 3As shown, a sealing gasket 208 is fixedly provided on a side of the first shell 203 that contacts the second shell 204. When the first shell 203 and the second shell 204 are connected, the sealing gasket 208 plays a role of buffering and sealing, thereby preventing water leakage.

[0055] like Figure 6 As shown, a plurality of sealing balls 307 are evenly distributed along the circumference of the sealing ring 306 and located in the installation groove 308. When the joint 202 is docked with the water inlet 101, the sealing balls 307 are deformed under the action of pressure to fill the possible tiny gaps and achieve a tighter seal. At the same time, the sealing balls 307 are adaptively deformed according to the shape and size of the joint 202, thereby improving the adaptability and flexibility of the sealing mechanism 300.

[0056] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
