Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a ship capable of reducing wave-making resistance. Background Art

[0002] For the existing common propeller arrangement at the stern, the center of gravity of the hull is in the middle of the ship, while the propulsion force acts on the stern. When the ship is sailing, the water at the stern is a negative pressure area, and the propeller is placed in the negative pressure area. Obviously, the efficiency of the propeller is difficult to fully exert, and surfing is caused at the bow. This is wave-making resistance. The higher the speed, the greater the wave-making resistance.

[0003] A Chinese patent document CN2429433Y discloses a device for reducing the wave-making resistance of a ship during navigation, which is to set one or more water pipes below the waterline of the hull, with the pipes opening at the bow and the stern, and a propeller set in the middle of the pipe. When the ship is sailing, the propeller sucks the water from the bow into the pipe and transports it to the stern for discharge, so as to reduce the wave-making resistance of the ship during navigation; however, the method of reducing the wave-making resistance of the ship during navigation needs to be further optimized.

[0004] Therefore, we provide a ship that can reduce wave resistance. By setting a U-shaped bottom hull at the bottom of the hull, a pump group is used to suck water in the bottom hull, so that the water at the bow is discharged through the side and stern of the ship, thereby reducing the wave resistance of the ship when sailing.
