Description
Technical field
The present invention relates to Prospect of Marine Fire Protection decision commanding technical field, specifically a kind of fire prevention side for limiting ship fire sprawling
Boundary and Smoke prevention border rapid generation.
Background technology
Naval vessel due to the demand of operation, carry substantial amounts of inflammable and explosive dangerous goods, such as fuel oil, jet fuel, ammunition with
And all kinds of electrical equipments.Ship fire Dangerous Load is more, and the possibility that fire hazard occurs is big.It is military especially on wartime, waterline
The attack of device can more cause the fire of naval vessel occurrence of large-area.During Prospect of Marine Fire Protection, it is necessary to accomplish directly fire extinguishing and limitation
Fire is combined.Because the thermal conductivity of hull steel design is strong, and fire and flue gas can be climing along the opening such as hatch door, hatch board
Prolong, therefore, how quickly to formulate the fire prevention border and Smoke prevention border of limitation fire and fire and smoke spread, be to stamp out a fire, reduce
Fire burnt area and the key for ensureing warship safety.
At present, when carrying out fire-fighting command, mainly according to files such as cabin plan, fire proof construction figure, plan of fire fighting
The mode that scene is consulted, fire prevention border and Smoke prevention border are set.In the case of single cabin is on fire, this method relative efficiency.
But, it is necessary to the fire prevention border and Smoke prevention border number that set are more in the case of multiple cabins are on fire, and segment boundary
It is to need preferential set to be set with emphasis.Now, if also relying on the subjective judgement of warship person, border will occurs and set not
Entirely, border sets inaccurate phenomenon, and fire and flue gas as a result will be caused not to be limited effectively, and spreads to and face cabin,
Even dangerous ammunition store, engine space and power station cabin etc., the vitality on serious threat naval vessel.
Prevent fires the setting not only company with the opening such as cabin spaces syntople and hatch door, hatch board on border, Smoke prevention border
Connect that relation is relevant, type, bulkhead fire proof construction grade, the segmentation situation of bulkhead also with cabin etc. are closely related, it is necessary to many
The overall collection and analysis with structural information in naval vessel.Prevent fires border, Smoke prevention marginal analysis result not only include will be in which cabin
Room sets fire prevention border, Smoke prevention border, in addition to needs to carry out spraying cooling, and preferential and emphasis to which bulkhead, deck
The bulkhead of spraying cooling.Therefore, the rapid generation on fire prevention border and Smoke prevention border how is established, is Support, Command person's standard
Really, the key of fire-fighting command work is efficiently carried out.
The content of the invention
The present invention provides a kind of fire prevention border for limiting ship fire sprawling and Smoke prevention border rapid generation, Ke Yiti
The fire-fighting command ability of high naval ship commander, Support, Command person is accurate, efficiently carries out fire-fighting command work.
A kind of fire prevention border for limiting ship fire sprawling and Smoke prevention border rapid generation, it is characterised in that including such as
