Description

Technical Field

[0001] The utility model relates to the technical field of heptafluoropropane fire extinguishers, in particular to a suspended heptafluoropropane gas fire extinguishing device. Background Art

[0002] Heptafluoropropane is a colorless, almost odorless, non-conductive gas that can be liquefied and stored at low pressure. When used as a fire extinguishing agent, it has the advantages of high fire extinguishing efficiency (low fire extinguishing concentration required), rapid fire extinguishing, rapid gasification after fire extinguishing, no residue, no secondary pollution, low toxic side effects, and zero ozone depletion potential (ODP). Therefore, it is called clean gas and is the most ideal substitute for halon fire extinguishing agent.

[0003] After searching, the patent (application number: 202221612697.4) discloses a "suspended heptafluoropropane gas fire extinguishing device". The device can make the two clamping plates move away from each other and release the clamping of the support plate through the cooperation between the connecting plate and the slider and the cross bar and the reset spring. At the same time, the reset spring is compressed, and the clamping rod and the side hole can be connected through the cooperation between the side rod and the side plate. The support plate can be rotated through the cooperation between the support column and the side block and the connecting shaft and the mounting block, so as to facilitate the adjustment of the angle of the storage cylinder and facilitate large-area fire extinguishing. However, the device has the following problems during use:

[0004] First, when the device finds a dangerous situation, in order to adjust the spray range of the fire extinguisher, it is necessary to manually adjust the corresponding structure. However, in a fire environment, the environment is very harsh, and manual operation is very dangerous.

[0005] In addition, the spraying method of this fire extinguisher only relies on the nozzle at the bottom of the storage cylinder. It is unclear how the nozzle can spray HFC-227ea gas in time. If the HFC-227ea gas cannot be sprayed out in the first time when a fire is discovered, it is easy to cause the fire to spread and expand the losses. Utility Model Content
