the upper floating tire 1 and the lower floating tire 2 are both annular, the middle parts of the upper floating tire 1 and the lower floating tire 2 are respectively provided with an upper central tire 7 and a lower central tire 8, the upper central tire 7 and the lower central tire 8 are communicated with a gas storage bottle through an air pump 13, a first bidirectional air valve is arranged at the communication part of the upper central tire 7 and the lower central tire 8 with the gas storage bottle, the air in the gas storage bottle can flow into the upper central tire 7 and the lower central tire 8, and the air in the upper central tire 7 and the lower central tire 8 can also flow into the gas storage bottle through the action of the air pump 13, so when the air needs to be discharged out from the upper central tire 7 and the lower central tire 8, the air can be filled into the gas storage bottle, and the waste of the air is prevented;

a zipper 9 is connected between the upper central tire 7 and the lower central tire 8 and the upper floating tire 1 and the lower floating tire 2, the upper central tire 7 and the upper floating tire 1 are provided with a connection point, then the upper floating tire 1 and the upper central tire 7 are connected together through the zipper 9, and when the upper central tire 7 is filled with gas, the upper central tire 7 has the same function as the upper floating tire 1, namely, the buoyancy is increased; after the upper central tire 7 and the lower central tire 8 release gas, the upper central tire 7 and the lower central tire 8 are held down, a hole which can be communicated with the two bearing spaces is formed in the positions of the upper central tire 7 and the lower central tire 8, and personnel in the raft can move in the two bearing spaces from front to back when sea waves come, so that the weight borne by the two bearing spaces is balanced, the possibility of vertical overturning of the life raft under the impact of the sea waves can be reduced, and the discomfort of the body caused by 360-degree rotation of the personnel in the life raft can be avoided;

the bottom surfaces of the upper floating tire 1 and the lower floating tire 2 form a raft bottom, anti-rotation assemblies 11 are arranged on the raft bottom, fixed shoulder straps 12 and fixed sitting bags 1201 are fixed on the anti-rotation assemblies 11, each anti-rotation assembly 11 comprises a supporting plate 1101, a bearing clamping rod 1102, a groove 1103 and a clamping seat 1104, the bearing clamping rod 1102 is fixedly arranged at the center of the supporting plate 1101, the groove 1103 is arranged at the raft bottom, the clamping seat 1104 is installed inside the groove 1103, the bearing clamping rod 1102 is rotatably clamped inside the clamping seat 1104, the clamping seat 1104 and the bearing clamping rod 1102 both have certain hardness and can support the weight of a normal person, the supporting plate 1101 is stored in a tool bag in advance as a tool, when wind and wave is heavy, the supporting plate 1101 can be taken out, the bearing clamping rod 1102 is clamped in the clamping seat 1104, the bearing clamping rod 1102 can rotate relative to the clamping seat 1104, and meanwhile, the human body 1101 is fixed on the supporting plate by the fixed shoulder straps 12 and the fixed sitting bags 1201 fixed on the anti-rotation assemblies 11, when the valve body rotates under the impact of sea waves, a human body keeps vertically downward under the action of gravity, so that the condition that the body is uncomfortable due to the rotation of the human body can be prevented;

in addition, an annular bag 10 is arranged at the raft bottoms of the upper floating tire 1 and the lower floating tire 2, the annular bag 10 is communicated with an air storage bottle, a second air valve 1001 is arranged on the annular bag 10, when wind and waves come, a supporting plate 1101 is installed, the second air valve 1001 is opened, the air in the air storage bottle props open the annular bag 10, the annular bag 10 is annular and is positioned at the periphery of the supporting plate 1101, therefore, two arms of people in the life raft are hung on the fixed shoulder straps 12 in a hanging mode and sit on the fixed seat bag 1201, when the life raft rotates, two feet of the people in the life raft can intermittently step on the annular bag 10 to provide upward force for the body, the phenomenon that the weight borne by the groove 1103 is too large due to the too large weight of the human body is avoided, the phenomenon that the joint of the groove 1103 and the raft bottoms of the upper floating tire 1 and the lower floating tire 2 is damaged is avoided, and the service life of the life raft is prolonged;

when the wind and the wave pass, the air in the upper central tire 7 and the lower central tire 8 is discharged again, the personnel in the two bearing spaces need to be transferred into the same bearing space, and the life raft is turned from the transverse state to the vertical state, the inner parts of the upper canopy 3 and the lower canopy 4 are uniformly provided with top plates 5, the sum of the areas of the top plates 5 is the same as the area of the top surfaces of the upper floating tire 1 and the upper central tire 7, namely, after the upper canopy 3 and the lower canopy 4 are completely contracted, the top plates 5 are clamped at the two sides of the upper floating tire 1 and the lower floating tire 2 side by side to form a whole with the upper floating tire 1 and the lower floating tire 2, the inner walls of the upper canopy 3 and the lower canopy 4 are provided with air bag support bars 6 at the positions of the top plates 5, the air bag support bars 6 are tightly adhered to the inner walls of the upper canopy 3 and the lower canopy 4, the contact point of the air bag support bars 6 and the top plates 5 is fixed with the outer walls of the upper canopy 3 and the lower canopy 4, the first air valve 601 is arranged on the air bag support bar 6, the air bag support bar 6 is communicated with the air storage cylinder through the air pump 13, namely when the upper canopy 3 or the lower canopy 4 is contracted, the air in the upper canopy 3 and the lower canopy 4 is collected into the air storage cylinder through the air pump, at the moment, the upper canopy 3 and the lower canopy 4 are in a folding state, personnel in a bearing space can step on the top plate 5, the top plate 5 has upward lifting force to the personnel under the action of seawater buoyancy, the personnel can be easily transferred into the other bearing space through the spaces at the upper central tire 7 and the lower central tire 8 under the lifting force, of course, the air in the upper canopy 3 or the lower canopy 4 needs to be slowly released in the transfer process, the upper canopy 3 and the lower canopy 4 can also block the pressure of seawater to transfer all the personnel, so that the personnel are prevented from being squeezed by the seawater, and the personnel are transferred into the other space, the upper canopy 3 or the lower canopy 4 is not filled with gas, the rough shape of the upper canopy is maintained under the action of the airbag supporting strips 6, the buoyancy at two ends of the life raft taking the upper floating tire 1 and the lower floating tire 2 as shafts is unbalanced, and personnel pull the fixed shoulder straps 12, the fixed seat bags 1201 and the annular bags 10 to move to one side, so that the whole valve body is turned over from a transverse state to a vertical state, and the life raft is straightened;

after the life raft is straightened, the upper canopy 3 or the lower canopy 4 at the bottom is upwards close to the upper floating tire 1 or the lower floating tire 2 under the buoyancy of seawater, the part which is not supported by the air bag support strips 6 is upwards folded, then the air in the air bag support strips 6 is slowly released, the top plate 5 supported by the air bag support strips 6 slowly moves upwards and is uniformly arranged below the upper floating tire 1 or the lower floating tire 2, the middle parts of the upper floating tire 1 and the lower floating tire 2 are inwards sunken, the volume values of the sunken parts of the upper floating tire 1 and the lower floating tire 2 are the same as the volume values of the upper canopy 3 and the lower canopy 4, namely the upper canopy 3 and the lower canopy 4 can be completely accommodated in the sunken parts of the upper floating tire 1 and the lower floating tire 2, meanwhile, the top plate 5 is clamped below the upper floating tire 1 and the lower floating tire 2, so that the surface of the life raft, which is contacted with the seawater, is as flat as possible, when the life raft needs to be pushed by the seawater to move, can not be subjected to large seawater resistance.
