[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0030] A large-caliber electronic water meter with emergency protection and alarm based on pressure sensing includes a water meter body 1, a fixing cylinder 2 is provided on the top of the water meter body 1, an electronic meter core 3 is provided inside the fixing cylinder 2, an alarm protection mechanism 4 is provided on the side wall of the water meter body 1, and a sealing antifreeze mechanism 5 is installed on the top of the fixing cylinder 2;

[0031] The alarm protection mechanism 4 includes an installation tube 401, a placement groove 402, a pressure sensor 403, a cover 404, an information processing module 405 and an audible and visual alarm 406. The installation tube 401 is arranged at the top of the water meter body 1, the placement groove 402 is opened on the inner wall of the installation tube 401, the pressure sensor 403 is arranged inside the placement groove 402, the detection end of the pressure sensor 403 is located inside the water meter body 1, the cover 404 is threadedly connected to the top of the installation tube 401, the information processing module 405 is installed on the top of the water meter body 1, the audible and visual alarm 406 is installed on one side of the water meter body 1, and the information processing module 405 is electrically connected to the electronic watch movement 3, the pressure sensor 403 and the audible and visual alarm 406.

[0032] Specifically, such as Figure 4 As shown, a protective mesh cup 11 is provided inside the mounting cylinder 401 , and one end of the pressure sensor 403 is located inside the protective mesh cup 11 .

[0033] Specifically, such as Figure 4As shown, a sealing insert ring 12 is provided at the bottom of the cover 404 , and a slot 13 is provided at the top of the pressure sensor 403 , and the sealing insert ring 12 is plugged into and matched with the slot 13 .

[0034] Specifically, such as Figure 1 As shown, flow stabilizing impellers 14 are provided at both ends of the water meter body 1 .

[0035] The electronic watch movement 3 is mainly used for water flow detection and signal processing. The pressure sensor 403 is placed in the placement groove 402 in the installation tube 401. Its detection end can be extended into the water meter body 1 to detect the pressure change of the water flow. The detection end of the pressure sensor 403 is deep inside the water meter body 1 and can sense the change of water flow pressure in real time. When the water flow pressure exceeds the preset safety range, the pressure sensor 403 will immediately transmit this signal to the information processing module 405. The information processing module 405 receives data from the electronic watch movement 3 and the pressure sensor 403, and performs comprehensive analysis and processing. Once abnormal data is detected (such as water flow pressure is too high or too low, water flow is too large or too low), the information processing module 405 will immediately trigger the sound and light alarm 406, and emit a loud sound. The alarm sound and obvious light signal are used to remind the operator to pay attention and take corresponding emergency measures. The protective net cup 11 inside the installation cylinder 401 protects the pressure sensor 403 to prevent it from being directly impacted by the water flow or interfered by impurities. The sealing ring 12 at the bottom of the cover 404 is plugged into the slot 13 on the top of the pressure sensor 403, which further enhances the sealing and waterproof performance of the entire device. At the same time, in order to ensure that the flow rate of the water meter is uniform during operation, flow stabilizing impellers 14 are set at both ends of the water meter body 1, which helps to improve the measurement accuracy. In this way, accurate measurement of the water flow and water pressure of the water meter body 1 is achieved, and an alarm warning can be implemented when the water pressure or water flow exceeds the predetermined threshold, reminding the user that the water flow pressure in the current water meter working environment is abnormal.

[0036] Specifically, such as Figure 5 As shown, the sealing antifreeze mechanism 5 includes a connecting tube 501, a sealing tube 502, a tempered glass 503 and an electric heating wire 504. The connecting tube 501 is threadedly connected to the top of the fixed tube 2, the bottom of the connecting tube 501 is in contact with the electronic watch movement 3, the sealing tube 502 is threadedly connected to the top of the connecting tube 501, the tempered glass 503 is installed on the top of the sealing tube 502, and the electric heating wire 504 is arranged between the connecting tube 501 and the sealing tube 502.

[0037] Specifically, such as Figure 5 As shown, a protective cover 6 is hingedly connected to the top of the sealing cylinder 502 , and a clamping strip 7 is fixedly connected to the top of the sealing cylinder 502 , and the protective cover 6 and the clamping strip 7 are clamped and matched.

[0038] Specifically, such as Figure 5As shown, a sealing groove 8 is formed on the top of the sealing cylinder 502 , a sealing gasket 9 is bonded inside the sealing groove 8 , and the sealing gasket 9 contacts the bottom of the protective cover 6 .

[0039] Specifically, such as Figure 5 As shown, a rubber ring 10 is bonded to the bottom of the sealing tube 502 , and the bottom surface of the rubber ring 10 is in contact with the electronic watch movement 3 .

[0040] The threaded connection between the connecting tube 501 and the sealing tube 502 enables the electronic watch movement 3 to be firmly installed in the fixed tube 2, and the sealing tube 502 and the tempered glass 503 are used to achieve sealing protection for the electronic watch movement 3. The electric heating wire 504 is arranged between the mounting tube 401 and the sealing tube 502, and the heat generated by the power is used to prevent the temperature around the electronic watch movement 3 from being too low, thereby playing an anti-freezing role. A protective cover 6 is hingedly installed on the top of the sealing tube 502. The protective cover 6 is clamped with the clamping strip 7 on the top of the sealing tube 502, which can effectively block the tempered glass 503 when not in use to prevent dust or moisture from entering. A sealing gasket 9 is installed in the sealing groove 8 opened on the top of the sealing tube, which can further enhance the sealing effect, prevent external moisture from entering through the gap, and protect the electronic watch movement 3 from being damaged by moisture. The rubber ring 10 bonded to the bottom of the sealing tube 502 provides additional sealing and buffering. In this way, sealing protection for the electronic watch movement 3 is achieved, and the electronic watch movement 3 can be heated at low temperatures to prevent frostbite and damage to the electronic watch movement 3.

[0041] By adopting the above technical solution, the problems of existing large-caliber electronic remote water meters that cannot monitor the water pressure inside the electronic water meter and issue a pressure overload alarm, cannot quickly provide emergency protection for large-caliber electronic water meters, and cannot issue an alarm when the water flow exceeds a defined threshold are solved.

[0042] Working principle: When the present application is in use, first, the electronic watch core 3 is mainly used for water flow detection and signal processing. The pressure sensor 403 is placed in the placement groove 402 in the installation tube 401, and its detection end can be extended into the interior of the water meter body 1 to detect the pressure change of the water flow. The detection end of the pressure sensor 403 goes deep into the interior of the water meter body 1 and can sense the change of water flow pressure in real time. When the water flow pressure exceeds the preset safety range, the pressure sensor 403 will immediately transmit this signal to the information processing module 405. The information processing module 405 receives the data from the electronic watch core 3 and the pressure sensor 403, and performs comprehensive analysis. Analysis and processing, once abnormal data is detected (such as water pressure that is too high or too low, water flow that is too large or too low), the information processing module 405 will immediately trigger the sound and light alarm 406, emitting a loud alarm and obvious light signals. The threaded connection between the connecting tube 501 and the sealing tube 502 allows the electronic watch movement 3 to be firmly installed in the fixed tube 2. The sealing tube 502 and the tempered glass 503 realize the sealing protection of the electronic watch movement 3. The electric heating wire 504 is arranged between the installation tube 401 and the sealing tube 502, and the heat generated by the power supply is used to prevent the temperature around the electronic watch movement 3 from being too low, thereby playing an anti-freeze role.

[0043] Finally, it should be noted that 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 above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
