Problems solved by technology

The disadvantage of this device is that the swing of the hydrofoil is completely dependent on wave regulation and cannot be actively controlled
[0008] To sum up, some of the existing wave wing limit adjustment devices need to consume a large amount of onboard energy of the unmanned boat for control and adjustment, which affects the endurance and self-sustainability of the unmanned boat; to both

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] The invention belongs to the field of wave energy-driven marine aircraft, and in particular relates to a hydrofoil and a wave-driven unmanned boat with a flap limit angle adjustment control device. The hull pitch motion energy capture and conversion devices are located at the bow and stern, and capture the pitch motion energy of the hull for limit adjustment. The wing plate limit angle adjustment control device is located in the bracket between the left and right wing plates, and the rotation angle amplitude is limited by the wing plate limit angle adjustment control device when the hydrofoil rotates. The angle control device is controlled by an electric push rod. The control system gives the required rotation angle amplitude according to the perceived wave motion, and controls the rotation angle of the limit device through the expansion and contraction of the ...

Abstract

The invention belongs to the field of wave energy driven marine aircrafts, and particularly relates to a hydrofoil with a wing plate limiting angle adjusting control device and a wave driven unmannedship. The wave driven unmanned ship is characterized in that hull pitching motion energy capturing and converting devices are located at the head and the tail and used for capturing hull pitching motion energy for limiting adjustment, the wing plate limiting angle adjusting control device is located in a support between a left wing plate and a right wing plate, the rotating angle amplitude is limited through the wing plate limiting angle adjusting control device when the hydrofoil rotates, a corner control device is controlled by an electric push rod, a control system gives a required rotationangle amplitude according to the sensed wave motion, and the rotation angle of a limiting device is controlled through stretching and retracting of the electric push rod. When a wave energy aircraftsails in sea waves with different wave heights and wavelengths, the limiting angle amplitude of the rotating motion of the hydrofoil is adjusted according to the preset rotating angle requirement, thewave energy aircraft can adapt to different sea conditions, it is guaranteed that the hydrofoil provides thrust under various sea conditions, and the comprehensive utilization efficiency of wave energy is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of wave energy-driven marine vehicles, and in particular relates to a hydrofoil and a wave-driven unmanned boat with a flap limit angle adjustment control device. Background technique [0002] Conventional marine vehicles generally carry fuel or batteries as a power source. Due to the limitation of displacement, the energy that can be carried is limited, and the endurance of the aircraft is short, making it difficult to perform long-term observation or combat missions. The ocean contains extremely rich clean energy, so people have shown great interest in using ocean energy as an energy source for ocean vehicles. At present, a lot of research has been carried out on ocean energy-propelled marine vehicle technology at home and abroad, mainly focusing on solar-powered underwater vehicles or unmanned boats, temperature difference energy-propelled underwater vehicles, wind or solar-powered unmanned boats, wave en...
