Abstract
The utility model relates to an inflatable life raft used for saving life in water, which comprises a floating tyre, tent poles, a raft bottom and a tent. The floating tyre, the tent poles and the raft bottom are made by rubber cloth which is formed by coating rubber layers on both faces of a piece of single-layer chinlon fiber fabric. The diameter of single fiber of the fiber fabric is 18-25 micrometres, and the thickness of the rubber cloth is 0.50 mm-0.75 mm. The inflatable life raft has the advantages of simple structure, easy manufacture and strong rubber cloth of which strength can reach ISO international standard. The utility model is suitable to be used for saving the distress people when a ship sailing on water come across shipwreck.
Description
The utility model relates to the inflatable liferaft that a kind of water survival is used.
The fixing at ordinary times system of inflatable liferaft is placed on the raft frame of gun wale.When boats and ships meet typhoon under sail, when contingency such as hit a submerged reef is wrecked, the occupant should get loose the liferaft trip mechanism immediately, and liferaft is slipped in the water automatically, the pressure gas that the steel cylinder in the raft is stocked is inflated the raft body automatically, liferaft inflation moulding.Wear the distress personnel of life jacket and climb up liferaft, cut off the connecting rope of raft body and boats and ships, draw from the scene, float at sea reaches the purpose of lifesaving.
In the prior art, inflatable liferaft is formed and is comprised floating tire, and floating tire top connects fluffy post, and floating tire bottom connects at the bottom of the raft, and fluffy post outside connects fluffy account; Be inflatable structure at the bottom of floating tire, fluffy post and the raft.Floating tire is formed by upper and lower two, is two independently air chambers.The come-up tire connects the fluffy post of inflation by the non-return charge valve.Floating tire bottom connects at the bottom of the inflatable rafts.The raft body of this liferaft (comprising at the bottom of floating tire, fluffy post and the raft) constitutes by the adhesive plaster of two-layer polyamide fibre silk therebetween rubber coated on both sides rubber layer is bonding.
The adhesive plaster manufacturing process complexity of this raft body adopts semi-cure behind the two-layer polyamide fibre silk therebetween rubber, then at adhesive plaster coated on both sides rubber layer, and, after cut-parts are adhesion-molded, make through baking again.This raft body adhesive plaster makes the adhesive plaster loss of strength reach 5-10% because of through twice baking, and the out of reach inflatable liferaft is to the ISO(International Standardization Organization of adhesive plaster intensity) standard (international standard).There are folding mark and color and luster irregular through the external sight of the raft of twice baking.Therefore, the manufacturing process complexity of this raft body, energy consumption height (because of twice sulfuration), production efficiency is low.In addition, form the adhesive plaster intensity out of reach iso standard that the single fiber thin (diameter is below 15 microns) of the polyamide fibre silk of this raft body is made.
The purpose of this utility model is by the structural development to inflatable liferaft, provides a kind of simple in structure, easily manufactured, adhesive plaster intensity to reach iso standard, the inflatable liferaft of appearance looks elegant.
The utility model is achieved in that the inflatable liferaft that this water survival is used, and comprises floating tire, and floating tire top connects fluffy post, and floating tire bottom connects at the bottom of the raft, and fluffy post outside connects fluffy account; Be inflatable structure at the bottom of floating tire, fluffy post and the raft.Be characterized at the bottom of floating tire, fluffy post and the raft constituting by the adhesive plaster of individual layer polyamide fibre or fabrics of polyester coated on both sides rubber layer.Baking technology behind the continuous synthetic fibre of adhesive plaster employing individual layer of this raft body (comprising at the bottom of floating tire, fluffy post and the raft) or the fabrics of polyester coated on both sides rubber layer, reduced in original technology the adhesive plaster loss of strength that causes because of twice baking, made the adhesive plaster intensity of raft body reach the iso standard of inflatable liferaft.The external sight of raft is attractive in appearance.
The diameter of the single fiber of individual layer polyamide fibre of the present utility model or fabrics of polyester is 18-25 micron (μ m).With the filament diameter of polyamide fibre silk fabric in the prior art is to compare below 15 microns, and the diameter of single fiber increases, and has improved the intensity that constitutes the adhesive plaster of raft body, makes it reach iso standard.
Adhesive plaster thickness behind individual layer polyamide fibre of the present utility model or the fabrics of polyester coated on both sides rubber layer is 0.50-0.75 millimeter (mm).Like this, both guaranteed to form the requirement of strength of the adhesive plaster of raft body, be no more than the weight requirement of ISO again raft body itself.
The rubber of individual layer polyamide fibre of the present utility model or polyster fibre coated on both sides rubber layer consists of:
Natural rubber (NR) 30-50%(weight),
Poly-chloroprene rubber (CR) 20-40%(weight),
Butadiene rubber (BR) 20-40%(weight).
The rubber layer of this component has satisfied raft body sun-proof, seawater corrosion resistance, oil resistant, cold-resistant and impact-resistant requirement.
The utility model compared with prior art has following advantage: owing to the adhesive plaster of raft body by individual layer polyamide fibre or fabrics of polyester coated on both sides rubber layer constitutes, adopt one time baking technology, reduced the adhesive plaster loss of strength that causes because of twice baking, made the adhesive plaster intensity of raft body reach iso standard.Attractive in appearance through the external sight of the raft of a baking, it is irregular not have folding mark and color and luster.Simplify manufacturing procedure, cut down the consumption of energy, improved production efficiency.Since overstriking the diameter of single fiber of fabric, improved the intensity of raft body adhesive plaster, make it reach iso standard.The rubber of the rubber layer that raft body adhesive plaster applies adopts natural rubber and neoprene to be mixed, to satisfy raft body sun-proof, seawater corrosion resistance, oil resistant, cold-resistant and impact-resistant requirement.Overcome that raft body adhesive plaster makes the adhesive plaster loss of strength reach 5-10% because of twice baking in the prior art, the external sight of raft has folding mark, color and luster irregular, oil resistant not, raft body processing technology complexity, energy consumption height, defective such as production efficiency is low.
Now in conjunction with the accompanying drawings an embodiment of the present utility model is specified.
