Problems solved by technology
[0002] In traditional ships, the center of gravity is basically below the center of buoyancy. Although these two forces act on the same straight line and in opposite directions, they do not act on one point. The resultant point of buoyancy is higher than the resultant point of gravity. To maintain the balance and stability of the hull, the bottom of most hulls needs to be equipped with a heavy body. The heavier the part above the water surface, the greater the buoyancy required, the greater the weight of the counterweight required, and the greater the buoyancy, the greater the immersion The larger the volume of the hull in the water, the greater the resistance of the ship moving in the water, the greater the power required, the slower the speed, and the more fuel it consumes; can it guarantee the transported load? How about finding a way to reduce the drag on the ship without changing the premise? The answer is to be able to find a more reasonable way

Embodiment Construction
[0008] from figure 1 and figure 2 It can be seen that this kind of ship is composed of upper and lower parts of the hull, and there is a streamlined and rigid structure in the middle that connects the upper and lower parts of the hull; image 3 As shown, since the center of gravity of the hull moves up to the buoyancy center point after the lower hull is discharged from the water during sailing, the hull will definitely turn over, and the overall balance of the boat can be dynamically adjusted by using the adjustable balance rudder and rudder, that is, in the When the center of gravity is higher than the buoyancy center of the ship, the angle of the balance rudder and the rudder can be adjusted to balance the hull to solve the problem of overturning; Figure 4 As shown, the lower part of the hull is filled with water when it is at rest, so that the center of gravity of the entire hull moves down to below the center of buoyancy, so the ship will not roll over in this state; i...

The invention discloses a ship with a gravity center above a buoyancy center point. The entire ship comprises an upper ship body and a lower ship body, wherein the upper ship body bears equipment, cargos and people and stays above and completely leaves off water surface during normal navigation; the lower ship body is a hollow ship body in a sealed streamline form, and the upper and lower parts of the ship are connected through a structure; the two sides of the lower ship body are provided with a balanced rudder and a rudder; when the gravity center of the ship is higher than the buoyancy center of the ship, the angles of the balanced rudder and rubber are adjusted to balance the ship body; and the lower ship body is provided with a water outlet / inlet channel which can totally or partially discharge water according to needs and fill the ship with water when the ship stops so as to lower the gravity center of the ship. The ship has the beneficial effects that the required buoyancy and the resistance are the smallest among various ships bearing the same payload, and certainly the power consumption is the lowest; and moreover, as the surge of the water surface cannot act on the ship body, the lower ship body can advance under calm water, and the entire moving of the ship body is very stable.
