Low-water-resistance vessel with speed-increasing cabin

Abstract

The invention discloses a low-water-resistance vessel with a speed-increasing cabin. The low-water-resistance vessel comprises a hull and the speed-increasing cabin located below the hull bottom. A horizontal air blocking section, a contracting section, a water entering section, an arching section and a water outlet section are sequentially arranged at the hull bottom from front to back in an end-to-end connection mode. An opening in the rear end of the speed-increasing cabin is a water outlet, and the water outlet is located in the tail of the hull. An opening in the front end of the speed-increasing cabin is a water inlet, and the upper end of the water inlet of the wall of the speed-increasing cabin is located in the middle of the horizontal air blocking section. The hull bottom surfaces of the horizontal air blocking section, the water entering section and the water outlet section are mutually parallel. The arching section arches upwards, and two impellers are arranged in the arching section side by side and located on the same horizontal position. The two impellers are respectively connected with a motor in a transmission mode. The speed-increasing cabin becomes thinner gradually from front to back, water is supplied to the impellers more sufficiently, the flowing speed of the water is rapider, and the front-sucking and rear-pushing effect is more obvious. Due to the fact that the arching section used for installing the impellers is arranged, the working area of the impellers is much larger than the sectional area of a cavity below the water outlet section, and therefore the traveling speed of the vessel is higher.

Description

[0001] [0002] This application is a divisional application, the original patent number is: 201110118724.2, the application date: April 29, 2011, and the invention title is: a boat with low water resistance. technical field [0003] The invention relates to a ship with low water resistance, and the ship includes large, medium and small ships, submarines, ships and aircraft carriers. 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 l...

AI Technical Summary

Problems solved by technology

In order to reduce the contact area and resistance between the ship and the water, the shape of the bottom of the ship is warped forward based on the horizontal plane. When the ship is running, the bottom surface of the front end of the ship is away from the water surface. If it is pumped into the speed-increasing tube, it is easy to have the above-mentioned air intake problem, which will affect the further improvement of the ship's speed

On the other hand, the water inlet diameter at the front end of the speed-increasing pipe is similar to the water outlet diameter at the rear end. When the impeller drains water at high speed, the water supply is limited, which ultimately affects the drainage speed, and the speed-up effect is not ideal.
