Boat with function of more sufficient water supply of impellers and function of rapid running

Abstract

The invention discloses a boat with the function of more sufficient water supply of impellers and the function of rapid running. A boat tip is arranged at the front end of a hull, the bottom face of the boat tip portion is flush with a load water line of the boat, an accelerating pipe is arranged at the bottom of the hull, boat sides are arranged on the left side and the right side of the front end of the accelerating pipe respectively, the upper ends of the boat sides are connected with the hull, the lower ends of the boat sides are flush with the lower edge of the accelerating pipe, a water inlet of the accelerating pipe is arranged between the two boat sides, one or more than two impellers are installed in the accelerating pipe, and the section, with the impellers, of the accelerating pipe serves as an arching section. The boat with the function of more sufficient water supply of the impellers and the function of rapid running further comprises a floating air-sealing mechanism which is composed of a floating air-sealing device and the two boat sides, wherein a base plate of the floating air-sealing device serves as an air-sealing floating plate, the front portion of the air-sealing floating plate is triangular, two vertical plates are fixedly connected to two side edges of the front portion of the air-sealing floating plate respectively, the front ends of the vertical plates are connected with each other in a butt joint mode, the bottom edges of the vertical plates are connected with the two side edges on the front portion of the air-sealing floating plate in a butt joint mode respectively, the inner side faces of the two vertical plates of the floating air-sealing device are attached to the two sides of the boat tip respectively, and the rear portion of the air-sealing floating plate is arranged between the two boat sides. The boat with the function of more sufficient water supply of the impellers and the function of rapid running is higher in running speed.

Description

[0001] [0002] This application is a divisional application. The original patent number is: 201110118713.4, the application date: April 29, 2011, and the invention name is: a fast-moving ship. technical field [0003] The invention relates to a ship capable of traveling fast. Background technique [0004] The current boats are very slow, and the concept of high horsepower and low speed has been adopted. The ensuing problem is that the speed of the ship cannot be increased simply by increasing the propeller speed. There are two reasons for this phenomenon. One is that the resistance of water is greater, and the deeper the draft, the greater the resistance; the other is air intake, because the ship is driving between water and air, and the natural flow rate of water is at a certain depth. There is a certain limit. When the speed of the propeller exceeds a certain limit, there will be no water for the propeller, and the water will be cut off. At this time, the air will be a...

Problems solved by technology

Because the entry of air cannot be sealed by relying on the existing technology, this problem has not been solved.

[0005] On the other hand, when the ship is running with no load or light load, the bottom of the front end of the ship is usually away from the water surface. When the ship is moving forward at high speed, the airflow is drawn into the speed-increasing tube from the space below the bottom of the front end of the ship along with the water, which is easy to appear. The problem of vortex air intake affects the further improvement of ship speed
