Throwing type inflatable life raft frame and using method thereof

Abstract

The invention discloses a throwing type inflatable life raft frame. The throwing type inflatable life raft frame comprises a base, a first rocker arm, a second rocker arm, a third rocker arm and an inflatable life raft releasing mechanism, wherein the first rocker arm, the second rocker arm, the third rocker arm and the inflatable life raft releasing mechanism are sequentially hinged, the base is of an oblique frame structure with the front portion lower than the rear portion, and the rear end of the base vertically extends upwards to form a support. Each rocker arm is of a frame structure and comprises two side bars and a plurality of rocker arm cross bars arranged at intervals. The lower end of the first rocker arm is hinged to the upper side of the front end of the base, the lower end of the third rocker arm perpendicularly abuts against the outer side of the upper portion of the support, and the inflatable life raft releasing mechanism is arranged on the lower portion of the base. The throwing type inflatable life raft frame is used in the way that 1, the rocker arms are pushed to be located on an inclined straight line; 2, a locking pin is pulled out, a pull rod is pulled, a binding system disengages from the raft frame, and the three rocker arms are unfolded to form an inclined slideway; 3, an inflatable life raft falls off along the inclined surface of the upper side of the base and rolls into water along the slideway. The throwing type inflatable life raft frame is simple in structure and convenient to use, and the inflatable life raft can roll into water quickly from the slideway.

Description

technical field [0001] The invention relates to ship life-saving equipment, in particular to an inflatable life-saving raft frame and a throwing method, belonging to the technical field of ship engineering. Background technique [0002] Throwing type inflatable life raft is a life-saving equipment used by people in distress when a ship is in distress. It is usually fixed in the life raft on the deck of the ship. When in use, it is released from the life raft and thrown to the side. In the outer water, at this time, the life raft releases the mixed gas from its own inflatable steel cylinder to make it inflated and formed to float on the water surface, and the people on board and in the water can log into the life raft to be rescued. Throwable inflatable liferaft has become the main lifesaving equipment of modern seagoing ships because of its advantages over other types of lifeboats, such as small deck area, simple use method, and quick lifesaving effect. The structure of the...

Problems solved by technology

The extended inverted rod stands upright on the inflatable liferaft frame, which not only hinders the crew's vision, but also greatly weakens the shock resistance and wind and wave resistance of the inflatable liferaft frame
