Description
Technical field
The present invention relates to a kind of rescue aid, specifically a kind of lifebuoy, belong to rescue aid technical field.
Background technology
The whole world has ten hundreds of citizens to drown every year, and basic reason is not having to carry with and energy is urgent
The rescue aid using.Existing lifebuoy, life raft etc. seal charger, typically with the sealing air ring after inflating, gas
Pad offer give people use, because in advance inflate and bulky it has not been convenient to carry.
The Chinese patent literature cn201385770(patent No.: quickly inflation immediately is rescued 200920084456) to disclose one kind
Raw circle, is made up of waterproof grommet and Mini compressed air storage tank, and Mini compressed air storage tank has valve and gas to derive
Mouthful, the two ends of air accumulator are connected in the inner surface of waterproof grommet, are provided with valve inside in waterproof grommet by adhesive-layer bonding.
The Chinese patent literature cn2688610(patent No.: 200420049310.4) disclose a kind of escape device, specifically one kind is worn in
Loins, at ordinary times for waistband shape, the rapid belt-type gas-filled lifebelt that can inflate rapidly during use;This belt type fast aeration lifesaving
Circle includes life saving air bag, and this life saving air bag is provided with inflation inlet;It is provided with check valve, gas storage cylinder at this inflation inlet, use
When, pull pull bar, by pricker, the bottleneck of gas storage cylinder is punctured, thus discharging the compressed gas in gas storage cylinder, and then
Quickly complete the inflation action to life saving air bag,
Above two escape devices, when inflation is not carried out, are equipped as back-up safety, small volume, foldable placement, with
Body carries, and solves existing sealing charger, bulky because of prior inflation it has not been convenient to the technical problem that carries, but
Have the disadvantage in that 1, charger inflationtime length (in 20 seconds), general drowning person can lose because choking water certainly in overboard 5 seconds
Rescue ability；2nd, operating difficulties, after drowning person is overboard, not only flurried but also fear is it is difficult to accurately completing by lower valve or pulling pull bar
Operation；And the lifebuoy being through loins has been submerged under water when drowned, the powerful resistance of water and behaviour is made to blocking of sight line
Make to become more difficult, 3, high cost, compressed air reservoir or steel cylinder need high pressure resistant, and it is filling and valve is installed and is required for very
High technical requirements, expensive.4th, compressed air reservoir or steel cylinder have certain deadweight in itself, increased inflation on the whole and set
Standby weight, increased the danger of rescue.
