Gas flow monitoring device and indoor safety protection system

Abstract

The invention relates to a gas flow monitoring device and an indoor safety protection system. The device comprises impeller blades, an impeller shaft, a permanent magnet, two bearings, a bearing fixing mechanism, a coil and a pipeline body, wherein the bearing fixing mechanism is mounted at the internal center of the pipeline body, the bearings are mounted at the two ends of the bearing fixing mechanism, the permanent magnet is mounted in the bearing fixing mechanism, one end of the impeller shaft is connected with the impeller blades, the other end of the impeller shaft penetrates through one bearing and the permanent magnet and then is rotatably connected with the other bearing, a rotor is formed by the impeller shaft and the permanent magnet, and the coil is fixedly arranged in the pipeline body and is distributed around the bearing fixing mechanism. The system comprises the gas flow monitoring device, a micro-current amplifier, a controller and a blower, wherein the micro-current amplifier is electrically connected with the coil and the controller, and the controller is further electrically connected with the blower. The gas flow monitoring device and the indoor safety protection system have the beneficial effects that the structure is simple, the connection is simple and convenient, the operation is convenient, the monitoring on gas flow is effectively realized, the monitoring operation is stable, and the coefficient of safety is increased.

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 it will continue to develop rapidly in the future. With the convenience and speed of gas entry to residents, safety issues cannot be ignored. According to the statistics of the China City Gas Association, there were 514 gas safety accidents nationwide in 2011, resulting in 143 deaths and 776 injuries, of which 51.61% were indoor gas leakage accidents. It can be seen that the high incidence and harmfulness of indoor gas accidents. [0003] Gas is a kind of flammable, explosive and poisonous gas. In recent years, accidents such as burning, explosion, suffocation and poisoning caused by improper use and gas leakage in households have been frequently reported in newsp...
