Abstract

An air inflation life raft comprises a raft bottom, a lower buoyancy chamber fixed on the raft bottom, an upper buoyancy chamber fixed on the lower buoyancy chamber, and principal body, which consists of arches bridged at the middle position of the upper buoyancy chamber. The life raft is characterized in that an annular aerating buoyancy tube is arranged fixedly under the raft bottom of the life raft principal body. As the technical solution is adopted, i.e. an annular aerating buoyancy tube is arranged fixedly under the raft bottom of the life raft principal body, the buoyancy of the tube offsets the own weight of the principal body. Moreover, when a plurality of liters of water goes into the life raft, the raft bottom surface can be properly higher than the water lever outside the life raft. Thus, the function of self-displacement can be realized conveniently.

Description

A kind of air inflation raft

(1) technical field

The utility model relates to a kind of air inflation raft.

(2) background technology

The tire of floating downward at the bottom of existing air inflation raft comprises raft, on being fixed at the bottom of the raft, be fixed on the come-up tire on the tire of floating downward and be connected across paulin post on the come-up tire midway location.This liferaft in use generally need possess from drain function, therefore, is equiped with drain gutter usually at the bottom of the raft, or other measure realizes from drain function, but all can not reach desirable effect, in some cases, even is difficult to realize from draining.This is owing to place the sole mass of the in running order liferaft of water, the raft baseplane is under the outer water surface of liferaft, some liters if intake in the liferaft this moment, the last plane of the some premium on currency that have in its liferaft even be lower than the outer water surface of liferaft, so draining can't realize.

(3) summary of the invention

The purpose of this utility model is to provide a kind of air inflation raft that has from drain function.

A kind of air inflation raft provided by the utility model, comprise by the tire of floating downward at the bottom of the raft, on being fixed at the bottom of the raft, be fixed on the come-up tire on the tire of floating downward and be connected across the liferaft body that the paulin post on the come-up tire midway location is formed, it is characterized in that the side is fixed with an annular inflatable buoyancy tube under the raft of described liferaft body.

Owing to adopted above-mentioned technical solution, promptly below at the bottom of the raft, be fixed with an annular inflatable buoyancy tube, make the quality of its buoyancy payment liferaft body self, and water inlet during some liter the in liferaft, its raft baseplane also can appropriateness exceed the outer water surface of liferaft, therefore, can realize from drain function easily.

(4) description of drawings

Fig. 1 is the front view of example structure of the present utility model;

Fig. 2 is the birds-eye view among Fig. 1;

Fig. 3 is the A-A cutaway view among Fig. 1.

(5) specific embodiment

As shown in Figure 1 and Figure 2, the example structure of the utility model air inflation raft comprises the annular inflatable buoyancy tube 2 that liferaft body 1 is beneath with the raft that is fixed on the liferaft body.This liferaft body 1 comprises at the bottom of the raft 11, be fixed at the bottom of the raft the tire 12 of floating downward on 11, be fixed on come-up tire 13 and two paulin posts 14 that are connected across come-up tire both sides on the tire 12 of floating downward.

As shown in Figure 3, the quality of the buoyancy of buoyancy tube 2 payment liferaft body 1 self, make the raft baseplane of liferaft body 1 exceed the outer water surface 3 of liferaft, and can reach a desired value at the diameter of buoyancy tube 2 time, even make some liters of in liferaft, intaking, 11 plane also can appropriateness exceed the outer water surface 3 of liferaft at the bottom of its raft, so just can realize from drain function easily.

Claims

1. air inflation raft, comprise by the tire of floating downward at the bottom of the raft, on being fixed at the bottom of the raft, be fixed on the come-up tire on the tire of floating downward and be connected across the liferaft body that the paulin post on the come-up tire midway location is formed, it is characterized in that the side is fixed with an annular inflatable buoyancy tube under the raft of described liferaft body.
