Description

Special foldable life raft of fire control

Technical Field

The utility model relates to a life raft technical field specifically is a special foldable life raft of fire control.

Background

The life raft is a boat for life saving without self-navigation capability. A certain amount of food and fresh water are prepared in the life raft for passengers to drift for rescue on the sea. The life rafts can be divided into rigid life rafts and inflatable life rafts according to the structural form.

The rigid life raft is also called a traditional life raft, and the structure of the rigid life raft is that a plurality of conjoined air boxes are made of galvanized iron sheets, aluminum alloy plates, stainless steel plates or hard plastic materials around the life raft to be used as the main buoyancy part of the life raft, and then the periphery of the life raft is covered or not covered with flame retardant materials; the top of the raft is provided with a fixed rigid canopy and an entrance and exit, and the bottom of the raft is provided with a wooden lattice board. The raft is fixed and stored on the ship gunwale inclined plane sliding frame or the deck of the driving platform at ordinary times, when the raft is released, the sliding frame fixing hook is opened, and the raft slides down by the sliding frame to be released into the water or the raft is released into the water by the raft hanging frame. The life raft has the biggest characteristics of simple structure and low manufacturing cost; but it is bulky, heavy and has few people.

Inflatable liferafts are further classified into inflatable liferafts, inflatable life-saving buoys, inflatable self-righting liferafts, and the like. The inflatable life raft is made up of upper and lower float tyres made of rubber material for providing buoyancy, double-layer water-proof nylon cloth for making tent, and small raft with tent made up by using gas through inflation into circular, elliptical or polygonal shape. The life raft body is folded and stored in the glass fiber reinforced plastic storage barrel together with the accessories. The inflatable life raft has advanced design, compact structure, good safety, convenient movement, simple operation and rapid formation, thus being widely used for various civil and military ships on the sea.

The inflatable life-saving floating tool has the same manufacturing materials, main structure, performance requirements, forming process, storage requirements, accessory equipment and the like as the inflatable life-saving raft except that the tent is not arranged, but the application method is only a throwing type.

In order to overcome the overturning condition which may be formed in the sea surface forming process of the inflatable life raft and avoid the difficulty of personnel launching the righting raft so as to meet the requirements of offshore survival personnel on safety and quick response, some manufacturers develop the inflatable self-righting life raft. Once the life raft is in an overturning state on the sea surface in the releasing process, the top of the life raft is circular, so that the contact surface with water can be reduced, the gravity center of the life raft can be positioned at the bottom of the life raft due to the sum of the weight of the raft body and accessories, and the life raft can be automatically righted after being inflated and formed.

Most of the existing rigid life rafts special for fire fighting have good bearing performance, but have certain defects. For example, the volume occupied is large, the transportation is inconvenient, and in order to solve the problem, the folding life raft special for fire fighting is provided.
