Collective life raft used for ship navigation

Abstract

The invention discloses a collective life raft used for ship navigation. The collective life raft used for ship navigation comprises an inflatable raft bottom. The inflatable raft bottom is composed of multiple gas bag units. Gas tension releasing channels are arranged between the adjacent gas bag units. Elastic blocking rods are arranged in the gas bag units. The two ends of each elastic blockingrod are provided with plugs capable of blocking the corresponding gas tension releasing channels on the two sides. Retainer rings are arranged on the inner sides of the plugs. An inflation port is formed in the inflatable raft bottom. The edge portion of the upper surface of the inflatable raft bottom is surrounded by an inflation enclosure ring. In the collective life raft, when the gas bag units are inflated with gas, the gas tension releasing channels can be tightly blocked through the plugs on the elastic blocking rods, the multiple elastic blocking rods mutually act, so that the inflatable raft bottom is tightly supported, the whole life raft is stable in structure and unlikely to be overturned, when the gas in the gas bag units is drawn out, the elastic blocking rods are loosened, the whole life raft is easy to store and carry, and the whole raft is simple in structure and convenient to use and can contain multiple people.

Description

technical field [0001] The invention relates to the technical field of ship navigation equipment, in particular to a collective life raft for ship navigation. Background technique [0002] Ship life-saving equipment is a general term for the special equipment and accessories installed on board to rescue people who fell into the water or evacuate the occupants when the ship is in distress. Generally include: rescue boats, lifeboats, life rafts, buoyancy aids, personal life-saving equipment, life-saving rope throwing devices, communications, pyrotechnic signals, and boarding and landing devices for boats. [0003] The life rafts in the prior art are too small to rescue many people. Collective rescue or collective distress often occurs at sea. The volume is too large, small tonnage ships cannot carry a large number of ships, and the equipment cost is high, and some structures are complicated to operate, the structure is not stable enough, and there is a risk of capsizing.
