An adjustable and retractable ship wave propulsion device

Abstract

The invention discloses a distance-adjustable and retractable ship wave propulsion device, which comprises a catamaran, a level adjustment assembly, a height adjustment assembly, a wing assembly and a float assembly, and each trapezoidal wing is connected with the float through a connecting rod The rod is hinged, each trapezoidal wing is connected with the lifting rack through the rotating shaft, the lifting rack is meshed with the gear, the gear motor controls the water entry depth of the trapezoidal wing, and the trapezoidal wing rotates around the rotating shaft, and the horizontal adjustment component pushes the corresponding component through the telescopic motor Horizontal adjustment realizes the horizontal distance adjustment of the wing. The float rises and sinks on the free liquid surface and its vertical movement drives the trapezoidal wing to rotate through the connecting rod to generate the power required for the ship to move forward. This device is a passive oscillating hydrofoil. The float at the free liquid surface absorbs the wave energy to the maximum extent and drives the hydrofoil to rotate, which solves the problem that the hydrofoil must be submerged to a certain depth in order to ensure that the hydrofoil does not come out of the water in the waves, and the range of motion of the wing decreases exponentially with the increase of the immersion depth. .

The wave propulsion device is one of the currently explored methods in the field of ship propulsion. The current wave propulsion device mainly uses two types of hydrofoils: active hydrofoil and passive hydrofoil. The active hydrofoil controls the hydrofoil through a complex and expensive control system. This implementation method requires additional energy consumption and an expensive control system, and the energy-saving effect is not obvious. However, the current passive hydrofoil mostly adopts a single hydrofoil structure, which only uses the energy of a certain depth of the wave. Moreover, the utilization of energy will decrease exponentially with the increase of the immersion depth of the hydrofoil, which is purely due to the problem of insufficient energy utilization.
