Description

NB-IOT gas meter with movable disassembly alarm function

Technical Field

The utility model relates to a gas table especially relates to a NB-IOT gas table with remove and dismantle alarming function.

Background

The NB-IoT (Internet of things) gas meter is a gas meter comprehensive management platform based on a mobile operator Internet of things private network, adopts a mobile communication module special for the Internet of things, takes a diaphragm gas meter as a base meter, and is additionally provided with a remote transmission electronic controller to realize data remote transmission and control. The NB-IoT Internet of things gas meter can be matched with a management system to realize functions of card-free prepayment, remote valve control, stepped gas price, price adjustment and the like, and the prepayment function of the meter end and the management system is required to be realized, and the data of the management system is finally used as the standard. When an existing NB-IoT (network B-IoT) gas meter is found in use, when people intentionally detach and move the gas meter or accidentally collide to cause position change of the gas meter, if the gas meter cannot be found in time, gas leakage can be caused, and further danger is caused.

Disclosure of Invention

According to the technical problem, the utility model provides a NB-IOT gas meter with movable disassembly alarm function, which is characterized in that the NB-IOT gas meter comprises a gas meter body and a movable disassembly alarm device, the movable disassembly alarm device is fixedly installed on the back of the gas meter body, the movable disassembly alarm device comprises an upper frame, a lower frame, a connecting beam, a trigger alarm, a fixing part, a trigger area, an elastic rope, a trigger ball, a bolt, a base surface and an installation hole, the upper frame is arranged on the upper side of the gas meter body, the lower frame is arranged on the lower side of the gas meter body, the two ends of the upper frame and the lower frame are respectively provided with the bolt, the connecting beam is arranged between the upper frame and the lower frame, the middle part of the connecting beam is provided with the trigger alarm, the periphery of the trigger alarm is equidistantly provided with the fixing part, the trigger area is arranged between, the elastic rope other end is equipped with the trigger ball, the elastic rope winding three-quarters circle that the trigger ball end was located is on the bolt, be equipped with the mounting hole on the base face, the bolt is installed in the mounting hole.

The upper frame and the lower frame are arranged in parallel, and the lengths of the upper frame and the lower frame are equal and are greater than the width of the gas meter body.

The elastic cord is initially in a stretched condition.

The length of the connecting beam is equal to half of the length of the upper frame and the lower frame.

The utility model has the advantages that: the utility model relates to a NB-IOT gas table with remove and dismantle alarming function, when someone is intentionally dismantling the removal to the gas table, or when collision results in the gas table position change unintentionally, at first can lead to becoming flexible of bolt, lead to the elasticity rope can't be suppressed after the bolt is not hard up, the elasticity rope is because the characteristic of self, elasticity can stretch the trigger ball to trigger alarm department, the trigger area is touched to the trigger ball, make the alarm start alarming function, can make the people in time discover that the gas table is dismantled or remove, thereby avoid dangerous emergence.

Drawings

FIG. 1 is a view of the main structure of the present invention;

FIG. 2 is a schematic structural view of a mobile dismounting alarm device;

fig. 3 is a schematic view of the position between the elastic rope and the bolt.

As shown in the figure, the gas meter comprises a gas meter body-1, an upper frame-2, a lower frame-3, a connecting beam-4, a trigger alarm-5, a fixing part-6, a trigger area-7, an elastic rope-8, a trigger ball-9, a bolt-10, a base-11 and a mounting hole-12.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

example 1:

the utility model relates to a NB-IOT gas meter with remove and dismantle alarming function, including gas meter body 1, remove and dismantle alarm device, gas meter body 1 back fixed mounting has the removal and dismantles alarm device, remove and dismantle alarm device again and include upper frame 2, underframe 3, tie-beam 4, trigger alarm 5, fixed department 6, trigger district 7, elastic rope 8, trigger ball 9, bolt 10, base face 11, mounting hole 12, upper frame 2 sets up at gas meter body 1 upside, underframe 3 sets up at gas meter body 1 downside, the both ends of upper frame 2, underframe 3 are equipped with bolt 10 respectively, be equipped with tie-beam 4 between upper frame 2 and underframe 3, upper frame 2, underframe 3 set up in parallel, upper frame 2, underframe 3 length equals and is greater than the width of gas meter body 1, 4 length of tie-beam equals the half of upper ledge 2, 3 length of underframe, 4 middle parts of tie-beam are equipped with trigger alarm 5, 5 periphery equidistant fixes 6 of trigger alarm, be equipped with trigger area 7 between the fix 6, fix 6 respectively with 8 one end fixed connection of elasticity rope, the 8 other ends of elasticity rope are equipped with trigger ball 9, 8 initial state of elasticity rope are in by tensile state, 8 winding three-quarters circles on bolt 10 of elasticity rope at trigger ball 9 end place, be equipped with mounting hole 12 on basic face 11, bolt 10 is installed in mounting hole 12.
