Elliptic sealed lifeboat

Abstract

The invention discloses an elliptic sealed lifeboat. The elliptic sealed lifeboat has all the advantages of a spherical escape capsule, and has the characteristic of being balanced and upright due to an elliptic shape. The elliptic sealed lifeboat is provided with a water preventer which is in the shape of an axe edge and used for splitting a water surface to reduce an impact force in case of being thrown in air by a tsunami or a surge and then falling into seawater, thus guaranteeing the safety of the lifeboat under the heaps of times of overturning and throwing of violent storm and roaring waves. The lifeboat has the following four characteristics that: 1, the lifeboat has leak tightness and water tightness; 2, the lifeboat can resist a high impact load; 3, the lifeboat can be got up from a ship in distress or from the sea; and 4, the lifeboat has good thermal insulativity so as to avoid the too low temperature of people in a low-temperature environment. According to the lifeboat, a propulsion system is installed on a keel, and can achieve a navigational speed of 1.9 kts via the drive of labour power; and an automatic water-charging ballasting chamber is arranged on the lower part of a main structure to guarantee the balanced, upright and comfortable state of the lifeboat in severe sea conditions. The lifeboat is light in boat body and simple in structure; a safety problem in storm is effectively solved via the sealed type; and by adopting a polyvinyl chloride heat-insulating material, the lifeboat is coldproof in winter and sunproof in summer, thus effectively increasing the safety factor of driving.

Description

1. Technical field: [0001] The invention relates to an elliptical sealed lifeboat, which belongs to the field of marine safety and lifesaving supplies. 2. Background technology: [0002] All kinds of sea lifeboats currently on the market have deficiencies to varying degrees. Most of them are open structures. Winter can't resist the invasion of exhibition games, and it doesn't have the function of protecting against storms. The tragedy that the drilling platform near Newfoundland sank in a storm once again shocked the world. There were no survivors in the disaster. After the recent earthquake in Japan, a spherical rescue capsule was developed. It is not as advanced as the ellipse in terms of appearance. The spherical floating object has no stable center of gravity in harsh sea conditions, and it is easy to roll over in the sea. It cannot be weighed and stands upright. There is no oval airtight lifeboat resisting stormy waves and tsunamis in the sea at present. 3. Contents...

Problems solved by technology

After the recent earthquake in Japan, a spherical rescue cabin was developed. It is not as advanced as the ellipse in terms of appearance. The spherical floating object has no stable center of gravity in the harsh sea conditions, and it is easy to roll over in the sea. It cannot be weighed and stands upright.

At present, there is no oval airtight lifeboat against stormy waves and tsunamis in the sea
