Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The present invention will be further described with reference to the accompanying drawings and the detailed description.

Referring to fig. 1 and 2, a disassembly-preventing type non-magnetic NB-IOT water meter includes a protection box 1, a containing cavity 11 and a battery compartment 12 are provided on the protection box 1, the containing cavity 11 is provided with an electronic module 2, the battery compartment 12 is provided with a battery and is connected with a cover plate 13, the electronic module 2 is provided with a sensor 3 at a corner near one side of the battery compartment 12, the battery compartment 12 is connected with a battery compartment flip 4, the battery compartment flip 4 can rotate around the battery compartment 12, the inner side wall of the battery compartment flip 4 is provided with a magnetic steel 7, the magnetic steel 7 is arranged right opposite to the sensor 3, the battery compartment flip 4 is fixedly provided on the battery compartment 12 through a screw one 5, that is, under normal conditions, the battery compartment flip 4 is fixed by the screw one 5 and cannot rotate, and then the screw one 5 holes are covered by a plug 6, so that not only the protection function but also is beautiful. In order to prevent the whole protection box 1 from being dismounted from the water meter and not sending signals, the protection box 1 is connected with a bottom plate 9 through an inner buckle 91 and a second screw 8, the second screw 8 is arranged in the battery bin flip cover 4, a plurality of mounting holes 92 connected with the water meter are formed in the bottom plate 9, the screws penetrate through the mounting holes 92 to be mounted on the water meter when the bottom plate 9 is mounted on the water meter, the second screw 8 can only be taken down when the bottom plate 9 is dismounted, the second screw 8 is mounted in the battery bin cover plate 4, namely the second screw 8 can be taken down when the battery bin cover plate 4 is required to be turned over, the bottom plate 9 is also protected from being dismounted from the water meter, and the whole protection box 1 is prevented from being dismounted from the water meter.

For higher sensitivity, the sensor 3 is a reed switch.

For later maintenance personnel dismantles, screw two 8 are installed in last spliced pole 14 and the lower spliced pole 93 that mutually supports the setting, last spliced pole 14 and lower spliced pole 93 set up respectively on the preceding terminal surface of protection box 1 and bottom plate 9, be equipped with lug 41 on the preceding terminal surface of battery compartment flip 4, lug 41 malleation is in go up spliced pole 14 top.

The utility model discloses a prevent tearing open principle: under normal conditions, the battery bin flip cover 4 is fixed by the first screw 5 and cannot be turned, the distance between the magnetic steel 7 and the sensor 3 is the shortest, the sensor 3 is in a disconnected state, and the electronic module 2 judges that the water meter works normally; if screw 5 is dismantled, battery compartment flip 4 just can overturn, will unpack apart apron 13 and take off the battery, just need go up battery compartment flip 4 upset, and the distance between magnet steel 7 and the sensor 3 is the farthest, and at this moment, sensor 3 is in the on-state, and electronic module judges for water gauge abnormal work, and then gives water management department with the signal transmission, can further promote the anti-dismantling performance of battery.
