Air seal mechanism for acceleration ship

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 invention relates to a fast-moving ship, which includes small and medium-sized ships and ships. Background technique [0002] 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. The reason for this phenomenon is mainly due to air intake, because the ship is driving between water and air, the natural flow rate of water has a certain limit at a certain depth, when the speed of the propeller exceeds a certain limit, the propeller will be dry If there is a water cut-off, the air will be added at this time, which is the so-called air intake. The water in the air intake is white, and the white color is the air bubbles. Water without air bubbles is colorless. The higher the rotation speed, the more intake air, the lower the proportion of water in the water vapor, and the smaller the thrust genera...
