Problems solved by technology

However, the existing semi-planing ships do not have the function of using spoilers to reduce the resistance of the ship, thereby reducing the power loss when the ship is sailing, and achieving the purpose of energy saving and emission reduction.

Abstract

The invention discloses a spoiler of a ship, which comprises a voltage controller, a speed reduction motor, a threaded steel column, a first boss and a three-layer convex plate structure. The three-layer convex plate structure fits with a molded line of the tail of the ship and further consists of a first spoiler plate, a first fixing plate and a second fixing plate, the first fixing plate and the second fixing plate are fixed to a stern, and the middle spoiler plate can move relative to the first fixing plate and the second fixing plate; an opening is disposed on the first fixing plate, and the first boss is fixed onto the middle spoiler plate via the opening; and the voltage controller adjusts output voltage, controls the speed reduction motor, and drives the threaded steel column to move relative to the first boss. Accordingly, the middle spoiler plate is driven to move relative to the first fixing plate and the second fixing plate, and purposes of improving the service condition of the ship, reducing running resistance of the ship, further saving energy and reducing emission are achieved. In addition, the spoiler device of the ship is simple and convenient in installation, low in cost, and remarkable in resistance reduction and energy conservation effects, and is excellent when used for commercial and military purposes.

Description

technical field [0001] The invention belongs to the technical field of ship design, in particular to a ship spoiler applied to the stern of a ship. Background technique [0002] Knownly, the navigation state of the ship is divided by the Froude number (also known as the length Froude number), wherein the Froude number: [0003] Fr = υ s gL [0004] In the formula, vs is the speed of the ship (in m / s), g is the acceleration of gravity (in 9.81m / s2), and L is the design waterline length of the ship (in m). Fr<0.4 is displacement sailing state; 0.4<Fr<1 is semi-sliding state; Fr>1 is sliding state. [0005] The semi-planing ship refers to the application of a semi-planing hull on a large ship, which combines the advantages of large displacement of a conventional displacement ship and good speed of a planing boat. For example, the U.S. Littoral Combat Ship (...
