Problems solved by technology

The propeller propeller not only needs to push the tens of thousands of tons of ship itself, but also pushes away the same tens of thousands of tons of water in front of the hull, so that the hull can move forward; the method of increasing the propeller speed and increasing the thrust also encounters cavitation and damages the propeller leaves; therefore, the ship can only crawl slowly in the sea like this

Embodiment Construction

[0016] When a moving object needs to pass through a solid, in order to overcome the blocking effect of the solid, people use the method of drilling first and then passing through; let it pass.

[0017] In a fluid medium, although a moving object can pass through it, the motion resistance increases with the multiplier of the speed. The faster the speed, the greater the resistance, which greatly inhibits the motion speed of the object.

[0018] The essence of motion resistance is: because the motion of the object invades the fluid in space, the fluid medium has a resistance to the motion of the object because it cannot be avoided; to eliminate resistance is to eliminate the conflict between the moving object and the fluid medium in space The environmental conditions that lead to the generation of resistance.

[0019] The concept principle of the present invention is to treat the fluid media such as water and air in the same way as the solid media. When the moving object moves i...

Abstract

The invention relates to a resistance-reducing energy-saving high-speed water absorption ship. A rectangular groove body is additionally formed in the lower portion of a ship body, and the rectangulargroove body and the ship body are combined to form a water suction channel. In the water suction channel, a plurality of propellers are respectively arranged at the bottom and two sides of the ship body, so that the front end and the rear end of the water suction channel and a centered propeller form a huge water pump. When the propellers rotate, the huge water pump sucks water from the front endof the water suction channel and pumps the water out towards the rear end of the water suction channel to push the ship to advance. And meanwhile, a hull water suction channel structure is utilized,so that the thrust is increased by increasing the number of the propellers, and the problem that the thrust is increased due to damage to propeller blades caused by the cavitation limit phenomenon isskillfully avoided. The water absorption ship has the advantages of reducing resistance, saving energy, improving ship speed, being remarkable in actual effect and the like; and the ship the is novelin idea, reasonable in structure and simple to manufacture, and has very high practical value and wide application prospect.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a drag-reducing, energy-saving, high-speed water-suction ship. Background technique [0002] Shipbuilding has a history of hundreds of years. From the perspective of development trend, ships are being built bigger and bigger. Why? The reason is very simple, because the sailing speed has been unexpectedly slow, so I simply made the boat bigger and jogged, and Dora jogged every time. [0003] So where is the problem of the slow speed of the ship? The problem is that the water has too much resistance to the hull! A large ship with a displacement of tens of thousands or even hundreds of thousands of tons suffers too much resistance in the water. The propeller propeller not only needs to push the tens of thousands of tons of ship itself, but also pushes away the same tens of thousands of tons of water in front of the hull, so that the hull can move forward; the method of increasing the...
