Embodiment Construction

[0012] The present invention will be further described below in conjunction with the drawings and embodiments.

[0013] Such as figure 1 As shown, this embodiment includes a hull 1 with a power engine, and also includes a speed-increasing cabin enclosed by the bottom of the ship and a speed-increasing bulkhead located below the bottom of the ship. The speed increasing cabin is only open at the front and rear ends. The bilge of the speed increasing cabin is at the same level.

[0014] From front to back, the bottom of the ship is composed of a horizontal choke section 3, a contraction section 4, a water inlet section 5, an arching section and a water outlet section which are connected end to end, each section having the same width, which is not less than the width of the bottom of the ship. The bottom surfaces of the horizontal choke section 3, contraction section 4, water inlet section 5 and water outlet section are all flat. The front end of the horizontal choke section 3 is lo...

Abstract

The invention discloses an air seal mechanism for an acceleration ship. The mechanism comprises a ship body, a speed increase cabin and a rectangular air seal floating plate, wherein the speed increase cabin is enclosed by a ship bottom and a speed increase cabin wall which is positioned below the ship bottom; the ship bottom sequentially comprises a horizontal air prevention section, a contraction section and a water feeding section which are connected with one another end to end one by one from the front side to the rear side; rear guide rails are arranged on the left side edge and the right side edge of the ship bottom surface of the contraction section; front guide rails which are parallel to guide rails right behind the horizontal air prevention section are arranged on the left side and the right side at the front end of the horizontal air prevention section; the four side edges of the air seal floating plate are connected with a flexible air baffle plate respectively; the top edges of the flexible air baffle plates are fixedly arranged on the ship bottom surface of the horizontal air prevention section; and the two side edges of each flexible air baffle plate are fixed on sliding blocks in the guide rails respectively. A height-adjustable seal body which is enclosed by the four flexible air baffle plates, the air seal floating plate and the ship bottom surface of the horizontal air prevention section is arranged and can automatically rise and lower along with the change of the water line of the ship, so that airflow space is not reserved in front of the water inlet of the speed increase cabin within a certain distance all the time, and the phenomenon of air inflow is effectively prevented.

Description

Technical field [0001] The present invention relates to a fast-moving ship. The ship includes small and medium-sized ships and ships. Background technique [0002] Nowadays, the speed of ships is very slow, and the concept of high horsepower and low speed has been adopted. The consequent problem is that simply increasing the propeller speed will not increase the ship's speed. The main reason for this phenomenon is air intake, because the ship is traveling between water and air, and the natural flow rate of water is limited at a certain depth. When the speed of the propeller exceeds a certain limit, the propeller will have no water. If there is a water cut, the air will be supplemented at this time. This is the so-called intake. The intake water is white, white is air bubbles, and water without air bubbles is colorless. The higher the speed, the more intake air, the lower the proportion of water in the water and the lower the thrust generated, so the propeller speed is very high...
