Fig. 2 is the front elevational schematic of a specific embodiment of the utility model buoyance lift structure;

Fig. 3 is the schematic side view of a specific embodiment of the utility model buoyance lift structure;

Fig. 4 is for adopting the scheme drawing of air cushion vehicle of the present utility model when being subjected to the alluvion state.

As shown in Figure 1, the buoyance lift structure that is used to control air cushion vehicle is by constituting around hard flank 2 and the described axle 3 that axle 3 rotates, when described hard flank 2 and axle 3 are arranged at hull 1 both sides, fluctuating along with wave, the hard flank can fluctuate around axle 3, described hard flank 2 can be made by steel plate or other hard material, described hard flank 2 can be similar platy structure, the hard flank 2 of described buoyance lift structure can be arranged side by side several, described several hard flanks 2 that are arranged side by side both can a shared axle 3, this 3 side that is connected in hull 1,2 of adjacent flanks are provided with locating part 14 (as shown in Figure 3), also can be separately link to each other with separately axle, this is connected in the side of hull equally

As shown in Figure 2, in order to make the buoyance lift structure adapt to the characteristic of air cushion vehicle better, when sealing adjacent hard flank 2 and fluctuating because of the staggered space that produces up and down, prevent a large amount of leakages of air-flow, the both sides of hard flank 2 respectively are provided with a side plate 9, hard flank 2 can be with described side plate 9 surperficial perpendicular, in order to adapt with hard flank 2, the bottom of described hard flank 2 can be provided with a base plate 12, hard flank 2 can be perpendicular with described base plate 12, the top connecting bridge of hard flank 2 is a hollow bushing 7, and described hollow bushing 7 is socketed on the axle 3, so that hard flank 2 rotates up and down around axle 3 by bearing 8.

Buoyance lift structure of the present utility model can be by the adjusted control of simple control setup, make the described hard flank 2 can be with the change of landform, as the ground that rises and falls or water surface wave 15 (as shown in Figure 4) and bob, nationality is to avoid the friction with interface 6, realize the full response effect of air cushion vehicle, the air stream outlet gap that is hard flank 2 and wave 15 keeps an about fixed constant, when just the hard flank floats with the interface, its clockwise moment and anticlockwise moment are about equally, and flank is in case upwards rotate, it is increasing that its anticlockwise moment then can become, clockwise moment is then roughly constant, this is to increase because sine θ is increase with the θ angle, in order to keep the roughly balance of two moments, need to reduce the length of the arm of force, like this, the regulating control mechanism of hard flank is oversimplified, promptly be provided with a regulating mechanism that together fluctuates with the hard flank, this regulating mechanism is to be made of an arc-shaped rail 4 and the rolling bodys 5 that are arranged on rolling in the arc-shaped rail 4, utilize the anticlockwise moment of regulating flank that moves of rolling body 5 centers of gravity, with the roughly balance of maintenance, reach the full response effect of air cushion vehicle with clockwise moment.
