Embodiment Construction

[0028] Such as Figure 1 to Figure 5 Shown is a hydrofoil device for anti-rolling at the tail of a hull, which includes a horizontal hydrofoil 1 , a vertical hydrofoil 2 , a hydrofoil rotating mechanism 3 and a hydrofoil mounting seat 4 . The tail of the hull 5 is connected to the hydrofoil mechanism 6 through the hydrofoil mount 4 and the hydrofoil rotating mechanism 3 .

[0029] A deceleration motor 8 is fixed on the hydrofoil mount 4 at the tail of the hull 5, and the deceleration motor 8 drives the worm 9; The two ends are respectively fixed on the end plate 12, the sleeve 7 is fixed on the hydrofoil mount 4, the middle part of the rotating shaft 11 is provided with a worm wheel 10, and the worm wheel 10 meshes with the worm 9 to drive the end plate 12 to rotate (such as figure 2 , image 3 shown).

[0030] The two end plates 12 are respectively fixedly connected to the vertical hydrofoil 2 in the hydrofoil mechanism 6, the V-shaped structure formed by two horizontal h...

Abstract

The invention discloses a ship body tail stabilization hydrofoil device and a working method, and belongs to the technical field of ship stabilization. The stabilization device is arranged at the tail of a ship body through a hydrofoil mounting seat and comprises a horizontal hydrofoil, a vertical hydrofoil, a hydrofoil rotating mechanism and the hydrofoil mounting seat. The hydrofoil rotating mechanism can drive the whole hydrofoil to rotate around the hydrofoil rotating mechanism rotating shaft. When the ship navigates normally, the vertical wings are in a vertical state to stabilize the ship; when the ship needs emergency braking, the whole hydrofoil is rotated backwards by a proper angle, so that the tail of the horizontal hydrofoil is close to the water surface, and the emergency braking effect is achieved; when a ship enters a port or passes through a shallow sea area, passive hydrofoil stabilization is not needed, the whole hydrofoil rotates to the horizontal position or the position above the horizontal position, and the whole hydrofoil leaves the water surface. According to the device, the problem that the ship shakes violently under the high sea condition is solved, pitching and heaving of the ship can be relieved efficiently, and the ship is safer and more comfortable in the sailing process.

Description

technical field [0001] The invention belongs to the field of ship anti-rolling devices, and in particular relates to a ship hull stern anti-rolling hydrofoil device. Background technique [0002] Under the influence of environmental loads such as waves, ships are prone to large-scale swaying motions under the influence of waves and other environmental loads, resulting in a significant reduction in the operability, safety and comfort of the ship. In order to reduce the adverse effects of the swaying motion of the ship on the comfort and structural safety of the ship, various anti-rolling devices have emerged as the times require. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention provides a hull stern anti-rolling hydrofoil device to slow down the ship's swaying motion under high sea conditions. [0004] The technical scheme of the present invention is as follows: a hydrofoil device for anti-rolling at the tai...
