A Local Gas Alarm Device Based on Internet

Abstract

The invention relates to the technical field of gas monitoring, in particular to an internet-based local gas alarming device. The device comprises a fixing frame, a box body, a suspension mechanism, agas monitoring alarm housing, a fixing belt, a winding mechanism, a filtering mechanism and an oxygen inhalation mechanism. According to the internet-based local gas alarming device, an alarm can befirmly arranged in front of the chest of a construction person through the suspension mechanism and the fixing belt and prevented from randomly swinging in the construction process, and meanwhile theconstruction person can visually view the gas concentration of a current position and timely discover a dangerous situation; when the gas concentration exceeds the standard, the construction person can take out an oxygen mask and put the oxygen mask on the nose and mouth, outside air can be filtered through the filtering mechanism to ensure that the construction person can inhale non-toxic air, and the device helps the construction person to escape as soon as possible; an oxygen tube can freely wind a winding cylinder and can be wound and released freely while the gas circulation is ensured, and the device is convenient to store and carry.

Description

technical field [0001] The invention relates to the technical field of gas monitoring, in particular to an Internet-based local gas alarm device. Background technique [0002] Gas is a mixed gas composed of methane, carbon dioxide and nitrogen escaped from coal and surrounding rock during coal mining. Gas is a harmful factor in coal mine production. It not only pollutes the air, but also when the gas content in the air reaches a certain value, it will It may cause an explosion and cause an accident. [0003] In mine operations, it is necessary to monitor the gas in real time, but the current monitoring equipment is mostly fixed-point monitoring, with limited coverage, and the construction personnel cannot monitor the gas concentration at their location, resulting in the construction personnel not being able to be the first to respond to dangerous situations. Time to evacuate; some of the monitoring equipment that is carried around is inconvenient to observe, the display is ...

[0003] In mine operations, it is necessary to monitor the gas in real time, but the current monitoring equipment is mostly fixed-point monitoring, with limited coverage, and the construction personnel cannot monitor the gas concentration at their location, resulting in the construction personnel unable to be the first to respond to dangerous situations. Time to evacuate; some of the monitoring equipment that is carried around is inconvenient to observe, the display is not intuitive enough, and affects the normal operation of the construction personnel; the monitoring equipment has a single function and cannot protect the construction personnel in case of danger
