Problems solved by technology

However, the combined control of T-shaped hydrofoils and wave-suppressing plates is the main method of anti-rolling for wave-piercing catamarans. In the research of catamaran anti-rolling motion, only the pitching and heaving motions are often considered and the influence of rolling motion on the hull is ignored, but in actual sailing, the influence of rolling motion on the hull cannot be ignored

Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 and figure 2 As shown, the upper end of the pillar 1 of the T-shaped hydrofoil is fixed on the bottom of the ship; the lower end is connected to the horizontal main wing 2; the pillar 1 is vertically connected to the horizontal main wing 2; the flap 3 is hinged to the horizontal main wing 2, and the hydraulic cylinder drives the swing of the flap 3 , 6 is the cylinder rod of the hydraulic cylinder; the aileron plate 4 is located at the two ends of the horizontal main wing 2 and there is a small gap between the horizontal main wing 2, which is convenient for the aileron plate to swing, and the aileron plate 4 and the horizontal main wing 2 are driven by hydraulic pressure. Transmission shaft connection, see below for the specific connection form.

[0021] figure 2 It is an overall schematic diagram of the p...

Abstract

The invention provides a T-shaped hydrovane and auxiliary wing plate composite roll-stabilization device which comprises a T-shaped hydrovane and two auxiliary wing plates, wherein when a catamaran needs roll stabilization, under the driving of a vertical hydraulic cylinder, the two auxiliary wing plates swing to different directions at the same time phase to achieve a roll-stabilization effect; when the catamaran does not need roll stabilization, the two auxiliary wing plates horizontally straighten to be meshed with a horizontal main wing of the T-shaped hydrovane under the action of a hydraulic cylinder, so that the span-chord ratio of the T-shaped hydrovane is increased, the lift coefficient of the T-shaped hydrovane is increased, and the roll-stabilization efficiency of the T-shaped hydrovane is improved. According to the T-shaped hydrovane and auxiliary wing plate composite roll-stabilization device, seakeeping of a high-speed ship under low ship speed is guaranteed, the probability of seasickness is reduced, and the working environment is improved.

Description

technical field [0001] The invention relates to an anti-rolling device, in particular to a composite anti-rolling device of a T-shaped hydrofoil and an aileron plate, which belongs to the field of ship control hydrofoils. Background technique [0002] Due to the structural characteristics of the wave piercing catamaran, it can sail at high speed under high sea conditions and has good sailing performance. However, the combined control of T-shaped hydrofoils and wave-suppressing plates is the main method of anti-rolling for wave-piercing catamarans. In the research of anti-rolling motion of catamaran, only the pitching and heaving motions are often considered and the influence of rolling motion on the hull is ignored, but in actual navigation, the influence of rolling motion on the hull cannot be ignored. According to the working principle of the catamaran wave control plate, it can be known that the wave control plate swings in opposite directions at the same time to reduce ...
