Description

Technical Field

[0001] The utility model relates to the technical field of alarm water meters, in particular to an anti-disassembly automatic alarm water meter. Background Art

[0002] A water meter is an instrument used to measure water flow, mainly used to record the cumulative flow of water. In order to prevent damage due to human intervention, the water meter will adopt an anti-dismantling automatic alarm function. If someone attempts to illegally dismantle the water meter or change the metering data, the alarm system will trigger an alarm to prevent water theft.

[0003] Currently, alarm water meters still have certain deficiencies. For example, the water meter does not have an alarm function when it is disassembled by non-technical personnel:

[0004] To overcome the problem of water meters not having an alarm function, a prior art Chinese patent (publication number: CN114166302A) discloses a multifunctional water meter with a disassembly alarm function. By driving a movable plate downward, when an extension rod at the bottom of the movable plate contacts a light touch switch, the power of the alarm light is turned off. At this time, when the water meter body is disassembled, the alarm will not be triggered because the power of the alarm light is turned off. Conversely, when unskilled personnel are disassembling, they are unaware of the existence of the alarm mechanism. Therefore, when disassembling, there is no contact between the extension rod and the light touch switch, so the power of the alarm light remains on, thus alerting illegal disassembly.

[0005] However, the alarm water meters currently in use still have certain shortcomings. The alarm function in the above document needs to be turned off using an external tool. If the tool is lost or forgotten, the operator will not be able to maintain or replace the water meter in time, which may affect the daily maintenance efficiency. Secondly, water leakage may occur at the connection of the water meter, resulting in waste of water resources. Therefore, the existing structure needs to be improved. Utility Model Content
