Abstract

The invention relates to a gas flow monitoring device and an indoor safety protection system. The device includes an impeller blade, an impeller shaft, a permanent magnet, a bearing, a fixed bearing mechanism, a coil and a pipeline body. The fixed bearing mechanism is installed in the center of the pipeline body. Bearings are installed on both ends of the bearing mechanism, and permanent magnets are installed in the fixed bearing mechanism. One end of the impeller shaft is connected to the impeller blade, and the other end of the impeller shaft passes through one of the bearings and permanent magnets, and is connected to the other bearing in rotation. The impeller shaft and the permanent magnet form a rotor, and the coils are fixed in the pipe body and distributed around the fixed bearing mechanism; the system includes the gas flow monitoring device, a micro-current amplifier, a controller, and a fan, and the micro-current amplifier is electrically connected to the coil and the controller , the controller is also electrically connected with the fan. The beneficial effect is that the structure is simple, the connection is simple and convenient, the operation is convenient, the gas flow monitoring is effectively realized, the monitoring operation is stable, and the safety factor is improved.

Description

technical field [0001] The invention relates to the field of gas safety monitoring and protection devices, in particular to a gas flow monitoring device and an indoor safety protection system. Background technique [0002] The development of my country's urban gas industry has gone through a glorious 30 years, and will continue to develop at a high speed in the future. With the convenience and speed of gas entering the household, safety issues cannot be ignored. According to the statistics of China Urban Gas Association, in 2011, there were 514 gas safety accidents across the country, resulting in 143 deaths and 776 injuries, of which indoor gas leakage accidents accounted for 51.61%. It can be seen that the high incidence and harmfulness of indoor gas accidents. [0003] Gas is a flammable, explosive, and toxic gas. In recent years, accidents such as burning, explosion, suffocation, and poisoning caused by various reasons such as improper use and gas leakage have been freq...
