Wireless gas detection device applicable to restricted space

Abstract

The invention discloses a wireless gas detection device applicable to a restricted space, comprising a gas detection control unit CPU, an acoustic alarm unit, an optical alarming unit, a display unit, a wireless module, a gas detection unit and a power supply unit. The wireless gas detection device applicable to a restricted space is characterized that the gas detection control unit CPU is connected to the acoustic alarm unit, the optical alarming unit, the display unit, the wireless module, the gas detection unit and the power supply unit. The beneficial effects of the invention are that the wireless gas detection device disclosed by the invention is easily applicable to detecting gas in the restricted space and utilizes the wireless communication to safely transmit signals.

Description

technical field [0001] The invention relates to a wireless gas detection and alarm device applied in a confined space. Background technique [0002] Confined spaces exist in petroleum, chemical, pharmaceutical, smelting and other fields. The defined confined spaces are all kinds of towers, kettles, tanks, tanks, furnaces, drums, pipes, containers and basements, manholes, pits, sewers or other closed and semi-closed places of chemical production units. Most of these confined spaces have flammable, toxic and other dangerous gases, especially in the daily inspection and maintenance process of confined spaces, there are great safety hazards. At present, there is no gas detection specifically for confined spaces in the industry. Products, the current confined space monitoring mostly uses conventional hand-held gas detection products for detection, and this detection method is a method of contact first and then detection, which requires people to hold a hand-held gas detection in...

Problems solved by technology

Most of these confined spaces have flammable, toxic and other dangerous gases, especially in the daily inspection and maintenance process of confined spaces, there are great safety hazards. At present, there is no gas detection specifically for confined spaces in the industry. Products, the current confined space monitoring mostly uses conventional hand-held gas detection products for detection, and this detection method is a method of contact first and then detection, which requires people to hold a hand-held gas detection instrument for monitoring, and in restricted spaces The general environment of space operations is relatively narrow and dark, and it is generally a closed or semi-closed place. When the gas is detected, people have already penetrated into the hazardous gas, which has a very high personal safety hazard.

Although the person in charge of the inspection is equipped with a gas mask, and according to the current requirements of the "Safety Regulations for Confined Space Operations of Chemical Production Units", it is a periodic inspection, that is, inspections are carried out at intervals, and workers will start operations after confirming safety , and most workers are not equipped with safety equipment such as gas masks, and the confined space environment is complicated, and dangerous gases are often triggered during inadvertent cleaning operations such as decontamination, causing serious personnel and property disasters
