Embodiment Construction

[0015] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0016] combine Figure 1-4 , the technical scheme realized by the present invention is:

[0017] Two left and right hydraulic cylinder devices are installed on the basis of common hydrofoils. The hydrofoil designed by the present invention has two states, working state and non-working state. The working state means that in order to reduce the draft of the ship during high-speed navigation, the distance between the hydrofoil and the bottom of the ship is controlled by the control device system through the upper rotating shaft of the hydraulic cylinder, so that the hydraulic cylinder swings with the rotating shaft as a fixed point to adjust the draft of the ship. It can reduce the resistance of the ship when it is sailing; the non-working state means that the hydrofoil is folded to the bottom of the ship when the ship is sailing at low speed. In addition, the axi...

Abstract

The invention provides a marine adjustable hydrofoil device. The marine adjustable hydrofoil device comprises a hull, a hydrofoil, a first hydraulic cylinder and a second hydraulic cylinder. A first hinge support and a second hinge support are fixed to the lower part of the hull, and a third hinge support and a fourth hinge support are fixed to the upper part of the hull. The top end of the firsthydraulic cylinder is connected with the first hinge support through a first rotating shaft, and the bottom end of the first hydraulic cylinder is connected with the third hinge support through a second rotating shaft. The top end of the second hydraulic cylinder is connected with the second hinge support through a third rotating shaft, and the bottom end of the second hydraulic cylinder is connected with the fourth hinge support through a fourth rotating shaft. The marine adjustable hydrofoil device can enable a ship installing the same to control the distance between the hydrofoil and the bottom of the ship and the angle of attack of the hydrofoil under different speed conditions, so as to reduce the draught of the ship and reduce the resistance of the ship in the sailing process to achieve the goal of energy saving and emission reduction.

Description

technical field [0001] The invention relates to a ship, in particular to a hydrofoil device of the ship. Background technique [0002] At present, some high-performance ships are equipped with fixed hydrofoils, which are characterized in that they cannot be adjusted once they are installed, that is to say, their relative position to the ship is fixed. However, when the ship sails at different speeds, the floating state of the ship is not constant, and the required distance between the hydrofoil and the bottom of the ship and the angle of attack of the hydrofoil are all different. From this, it can be known that under certain sailing conditions, the fixed hydrofoil may not be able to reduce the resistance, and may even cause negative effects such as increased resistance and reduced stability of the ship. Contents of the invention [0003] The object of the present invention is to provide a marine adjustable hydrofoil device that can not only adjust the distance from the bo...
