The specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

Referring to shown in accompanying drawing shown in 1 to 6, the utility model comprises two sidewalls 12 of hull 1 and hull bottom 11, screw propeller 2, described hull bottom 11 is planar structure, and hull bottom 11 is divided into hull section 111 and bow section 112, and wherein hull section 111 forms the first angle of elevation alpha with the water surface, screw propeller 2 is arranged on the front end of hull section 111, improve stability, prevent upset, power is provided.The utility model does not form pipeline or conduit, and the object of sidewall 12 is to make high pressure water not leak.

Described screw propeller 2 is installed side by side for single-blade or many oars.

When if ship sails on the water, its power F approximates resistance f, F=f when linear uniform motion; Resistance be mainly water to the resistance f1 of hull and air the resistance f2 to hull, and f2 is much smaller than f1, therefore when modeling, f2 can ignore.The size of f1 and the relation of hull shape: stream line pattern is better, and f1 is less; The size of f1 and the relation of displacement: displacement is less, and f1 is less; Displacement is directly proportional to draft, the relation of f1 and draft: absorb water more shallowly, f1 is less; The size of f1 and the relation of moving velocity: speed is higher, and f1 is larger.For example, in water-skiing, when surfboard and the water surface keep a fixed angle of altitude, under external force, during high speed slide, water levels off to the summation of surfboard and sportsman's weight to the power of lifting of slide plate, and buoyancy is close to zero so, displacement and draft level off to zero, and water is very little to the resistance of slide plate.Utilize this principle, designed the utility model, when ship navigates by water at a high speed on the water surface, hull bottom 11 is lifted under power effect at the water surface, the whole floating of hull 1, and displacement reduces, and the resistance that hull 1 is subject to reduces, and power consumption also reduces; 1 both sides respectively arrange the sidewall 12 of a similar captured air bubble machine alow, from the sidewall 12 to tail setting, make ship when travelling forward, and to keep the high pressure water of hull bottom 11 not run off to both sides, thereby make hull bottom 11 continue to be subject to the power of lifting from water; The screw propeller 2 of preposition power provides outside the required enough power of hull 1, also have two large functions concurrently, the one, stress point is positioned at hull 1 center of gravity foremost, can haul hull 1 moves ahead, than being arranged on stern, to promote the structure that hull 1 moves ahead steady, the 2nd, traditional ship is when overwater service, part waters near ship screw propeller 2 front ends can form higher-pressure region, navigation is formed to resistance, and preposition screw propeller 2 in the running, the high pressure waters of energy drainage fore, thus the resistance of water to hull 1 reduced, reduced energy consumption.
