Description
Technical field
The present invention is a kind of proving installation of life-float, especially for a kind of proving installation of inflatable life-raft pressure releaser made test in the life-float examination and test of products project.
Background technology
Life-float is a kind of lifesaving appliance that the boats and ships operation at sea must be equipped with, and is the instrument of saving oneself the most directly, the most rapidly after overwater accident takes place.At present, all use air inflation raft both at home and abroad, only need pulling to start drag-line, just can be the life-float carcass and inflate, rescue effect in the performance water.Along with China's rapid economy development, the demand of domestic life jacket constantly rises, and many in recent years enterprises have pushed product to international market.Air inflation raft; Have easy to use, inflation rapidly, the relief number is more and advantage such as good heat insulating; In case run into maritime affairs, just possibly in time succoured after using air inflation raft, be that in a single day comparatively desirable lifesaving equipment behind the casualty takes place boats and ships.China waters can both be used at boats and ships, tourism, operation at sea more greatly, just has been equipped with air inflation raft on the fishing boat, can succour the life that surpasses 200 fishermen every year, and this has demonstrated fully the importance of this production.
Air inflation raft (Life raft) meets can the resolve relevant requirements of MSC.81 (70) of SOLAS in 1974 amendment in 1996 and " international lifesaving equipment rule " thereof and Hai'an.Life-float packaging and storing at ordinary times is installed on the special-purpose raft frame of ship side in the fiberglass cartridge, can directly be thrown into raft in the water when dangerous situation occurring; Inflatable life raft can be shaped in automatic inflation, supplies distress personnel to take, and is too fast if boats and ships sink; Have little time raft is thrown in the water, when boats and ships sank under water certain depth, the hydrostatic release unit on the raft frame can be automatically-unhooked; Discharge life-float, can emerge automatic inflation of life-float is shaped.
Country's industry is in order to ensure the security of inflatable life raft; A series of product standards have been worked out; One of them CB3065-1994 " inflatable life raft is with hydrostatic force releasing means technical conditions " code test requirement; When the depth of water was no more than 4m, releasing means can be automatically thrown off the fixing rope of tying up of life-float cartridge, and it is separated with lash ship.(easily broken rope should break off when bearing 2.2 ± 0.4KN pulling force), performance test comprise the level sinking; The hydrostatic force releasing means is in the top, tilts 45 ° 100 ° then; The hydrostatic force releasing means is in the below, tilts 45 ° 100 ° then; Vertically vertical subsidence.The real ship different angles of all above-mentioned simulations are sunk, and the release degree of depth of life-float all must not surpass 4m.
Present present situation is that testing standard has had, but does not have concrete method of testing and proving installation; Each production or applying unit are all just built separately and are pieced together some individual event purpose mechanisms, the formality trouble of test, and test speed is slow; The data of test since the test data that the difference of mechanism draws also differ greatly, therefore, in today of greatly developing inflatable life raft; Urgent need has a kind of test speed fast, easy to operate, and mechanism for testing comes out in strict conformity with the mechanism for testing of CB3065-1994 standard.
Summary of the invention
The object of the invention is intended provides a kind of test speed fast, easy to operate, and test data is complete, in strict conformity with the mechanism for testing appearance of CB3065-1994 standard.
A kind of inflatable life-raft pressure releaser made test unit is characterized in that:
