Problems solved by technology
However, regardless of the type of transmission method, it will inevitably increase the power consumption of the entire meter. The gas meter is installed in the user's home as a civilian meter, and it is impossible to require the user to replace the battery frequently, which also affects the normal use of the gas meter.
The gas meter is used as a household instrument for conveying gas, and the national explosion-proof requirements do not allow external power supply, which caused the contradiction between the two

Embodiment Construction
[0017] A smart gas meter self-charging device includes a base meter casing 4.
[0018] The multi-pole magnetic steel 1 is fixed inside the magnetic steel bracket 2 .
[0019] The base meter casing 4 is fixed with a horizontal shaft box 3, and the magnetic steel bracket 2 is sleeved on the flange at the end of the horizontal shaft box 3 inside the base meter casing 4 to prevent falling off and can be placed on the flange at the end of the horizontal shaft box 3 turn.
[0020] The horizontal axis box 3 is provided with an induction coil 6, and the two ends of the induction coil 6 are correspondingly connected to the input end of the rectification filter voltage stabilization circuit, and the AC power transmitted from the induction coil 6 is rectified, filtered and stabilized to obtain a stable DC power.
[0021] The output end of the rectification filter voltage stabilizing circuit is connected to the input end of the energy storage element 9 to store direct current on the ener...

The invention discloses a self-charging device for an intelligent gas meter. The self-charging device for the intelligent gas meter is characterized in that: the multi-pole magnetic steel is fixed inside the magnetic steel bracket; a horizontal shaft box is arranged in the base table shell; the magnetic steel bracket is covered on the flange of the end of horizontal shaft box inside the base table shell; an induction coil is provided in the horizontal shaft box; the two ends of the induction coil are connected with the input end of the rectifying filter voltage stabilizing circuit; and the output end of the rectifying filter voltage stabilizing circuit is connected with the input end of the energy storage element. The magnetic steel bracket can be rotated on the flange of the end of the horizontal shaft box. According to the self-charging device for the intelligent gas meter, the original base table structure is not changed; the induction coil is added outside the gas meter, and according to the Faraday law of electromagnetic induction, the induction current is produced by cutting the magnetic induction lines by the induction coil through the transmission of the inner parts of the gas meter to provide energy for the gas meter electronic components, therefore, the self-sufficiency of the electric energy of the gas meter is realized, and the long plagued power problem of the gas meter for many years is solved.
Description
technical field [0001] The invention relates to the technical field of metering instruments, in particular to a self-charging device for a gas meter. Background technique [0002] The development trend of IoT and intelligence is changing with each passing day. Under the general trend of gas meter products, multiple series of IoT meters have also been derived, such as GPRS, ROLA, NB-IOT and series of small wireless. However, no matter which type of transmission method will inevitably increase the power consumption of the entire meter, the gas meter is installed in the user's home as a civilian meter, and it is impossible to require the user to replace the battery frequently, which also affects the normal use of the gas meter. The gas meter is used as a household instrument for conveying gas, and the national explosion-proof requirements do not allow external power supply, which caused the contradiction between the two. It is imminent to seek a new energy source. [0003] Th...
