Problems solved by technology

[0004] The present invention aims at the defects of large resistance of the existing displacement surface ships, and proposes a wheeled ship type, which changes the existing ship's underwater drainage body and the water hull into a fixed integral structure, so that the existing ship's drainage body is relatively water. The straight forward movement mode is changed to the combination of rotation and forward movement of the buoyancy wheel, and the water-immersed part of the rotating buoyancy wheel has the characteristic of moving in the same direction as the incoming water, so as to realize the reduction of the displacement relative to the water of the wheeled ship at a certain speed. The speed in the forward direction, so as to achieve the purpose of reducing water resistance

Embodiment Construction

[0014] Such as figure 1 Shown, the present invention comprises: port side buoyancy wheel 1,3, starboard side buoyancy wheel 2,4, buoyancy wheel shaft 5,6, port side buoyancy wheel shaft bearing 7,9, starboard side buoyancy wheel shaft bearing 8,10, water hull 11. The buoyancy wheels 1 and 3 on the port side and the buoyancy wheels 2 and 4 on the starboard side are partially submerged in water, the depth of immersion in water is less than the radius of the buoyancy wheels, and the shape of the section of the buoyancy wheels is streamlined; the hull 11 on the water is supported on the buoyancy wheel shafts 5 and 6, The hull 11 is completely separated from the water surface. The buoyancy wheel 1 on the port side and the buoyancy wheel 2 on the starboard side are connected through the buoyancy wheel shaft 5 to form a buoyancy wheel group. Connect with buoyancy wheel shaft 5,6 by port side buoyancy wheel shaft bearing 7,9 and starboard side buoyancy wheel shaft bearing 8,10 respect...

Abstract

The wheel type ship as one kind of transportation facility includes right and left buoyancy wheels with small part soaked in water, right and left buoyancy wheel bearings, and ship body supported on the buoyancy wheel shafts to over water surface. The right and left buoyancy wheels capable of rotating freely are connected via the buoyancy wheel shafts to constitute buoyancy wheel combination, the ship body is connected to the buoyancy wheel shafts via the buoyancy wheel shaft bearings. The wheel type ship has reduced navigation resistance, raised wave resistance, raised stability, improved laying status and other excellent performance, and has excellent application foreground in high speed ship.

Description

technical field [0001] The invention relates to a ship in the technical field of vehicles, in particular to a wheeled ship. Background technique [0002] The hull and superstructure of the existing ship are an inseparable integral structure, a part of the watertight hull is in the water, and the ship floats on the water surface and is driven by a propeller to sail. The hull submerged in water advances at a speed equal to the speed of the ship. Because water is a viscous fluid, it will generate greater frictional resistance and viscous pressure resistance. In addition, the ship is moving forward at the interface of two different fluids (water and air), which will generate wave-making resistance. No matter what kind of water resistance, its size is not only related to the water-immersed surface area and shape, but also depends on the moving speed of the drainage body relative to the water, and the water resistance is an exponential relationship above the square of the relativ...
