Hydrofoil and wave-driven unmanned boat with wing plate limit angle adjustment control device

Abstract

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 control system gives the required optimal limit angle according to the perceived wave motion, adjusts it by opening and closing the air valve and one-way vent hole on the cylinder, and verifies whether the optimal limit angle has been reached through the change of air pressure fed back by the barometer . When the wave energy vehicle sails in waves of different wave heights and wavelengths, according to the preset rotation angle requirements, the limit angle amplitude of the hydrofoil rotation motion can be adjusted to adapt to different sea conditions and ensure that the hydrofoil provides thrust under various sea conditions , greatly improving the comprehensive utilization efficiency of wave energy.

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...

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
