Description

Technical Field

[0001] The utility model relates to a gas detection technical device, in particular to a gas detection device which can be raised and lowered and is used in a shipyard workshop. Background Art

[0002] Combustible gas refers to a substance that can be ignited and is in a gaseous state at normal temperature and pressure. For example, hydrogen, acetylene, ethylene, ammonia, hydrogen sulfide, etc. Combustible gas has the general characteristics of gas. A combustible gas of one component is called a single gas; a mixture of two or more combustible gases is called a mixed combustible gas. Combustible gases are mixed in a certain proportion in the corresponding combustion-supporting medium, and can cause combustion or explosion under the action of an ignition source. Combustible gas is ejected from the nozzle at a certain flow rate, and its combustion speed is determined by the diffusion speed of the combustible gas and air.

[0003] Shipyard workshops use a large amount of natural gas (composed of methane and a small amount of ethane, propane, nitrogen and butane) as cutting gas. According to relevant national regulations, the release source of flammable gas that is lighter than air is in a closed or partially poorly ventilated semi-open workshop. In addition to installing detectors above the release source, flammable gas detectors should also be installed at the highest point in the workshop where gas is likely to accumulate. The flammable gas alarm is also called a gas leak detection alarm instrument. It consists of an alarm controller and a detector. The detector is installed at a location where flammable gas is prone to leak. When flammable gas leaks, the flammable gas detector detects that the concentration of flammable gas reaches the alarm value set by the alarm, and the alarm will send out sound and light alarm signals to remind people to evacuate, and start strong exhaust and shut down equipment and other safety measures.

[0004] Since natural gas is lighter than air, combustible gas detectors are usually installed at the highest point in the shipyard where gas is easily accumulated. This can monitor the concentration of combustible gas in the shipyard in real time, ensure production safety in the shipyard and improve the production environment.

[0005] Most of the flammable gas detectors installed on the top of the shipyard are fixed. When the factory building is constructed, the flammable gas detector is directly installed on the top of the factory building structure. With the rapid development of the domestic shipbuilding industry, the workshops of domestic shipyards are relatively tall. The existing method is to use scaffolding to climb for calibration and maintenance. Due to the need to build scaffolding, the verification and maintenance is time-consuming, and the efficiency of the verification and maintenance of the flammable gas detector is low.
