Fecha de publicación: 16/05/2023 Fuente: Wipo "IOT" The utility model discloses an anti-dismantle NB-IOT intelligent water meter, which relates to the technical field of water meters, and comprises a water meter body and an NB-IOT intelligent module, and the NB-IOT intelligent module is assembled on the top of the water meter body. According to the anti-disassembly NB-IOT intelligent water meter, through cooperative use of a movable column, a contact probe, a signal line and an NB-IOT intelligent module, after the anti-disassembly NB-IOT intelligent water meter and a water supply pipeline are connected and fixed, the water supply pipeline is in threaded connection with a connecting pipe and makes contact with the movable column, and therefore the water supply pipeline is connected with the NB-IOT intelligent module; the water supply pipeline pushes the movable column to move in the fixed pipe and extrude the contact probe, the NB-IOT intelligent module monitors the contact state between the contact probe and the movable column through a signal line, and when the water meter body and the NB-IOT intelligent module are directly disassembled without authorization, after the connecting pipe is separated from the water supply pipeline, the movable column is reset under the action of the elastic force of the spring, and the NB-IOT intelligent module is disassembled. The NB-IOT intelligent module sends an alarm signal to the outside after monitoring the state of the contact probe.
