Problems solved by technology

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.

Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] In the process of absorbing wave energy of conventional passive wave propulsion devices, because the devices are often fixed installations that can only meet the sea conditions of specific wave conditions, and because the front end of the vibrating wing will be affected by the induced resistance of the incoming flow when the front end of the vibrating wing moves head-on, thus reducing the Thrust generation reduces the efficiency of the propulsion unit. ...

Abstract

The invention discloses a retractable adjustable-distance ship wave propulsion device, which comprise double ship bodies, a horizontal regulation component, a height regulation component, a wing component and a floater component, wherein each trapezoidal wing is hinged to a floater connecting rod through a connecting rod and is connected with a lifting rack through a rotation shaft; the lifting rack is meshed with a gear; a gear motor controls the water entry depth of each trapezoidal wing, and each trapezoidal wing rotates around a rotation shaft; the horizontal regulation component pushes the corresponding component to be horizontally regulated through the work of a telescopic motor so as to realize the horizontal distance regulation of the wing; and the floater heaves on a free liquid level, and the vertical movement of the floater drives the trapezoidal wing to rotate through the connecting rod so as to generate power required for the ship to advance. The device belongs to a passive vibration hydrofoil, the floater is adopted to adsorb the wave on the free liquid level to a maximum degree to drive the hydrofoil to rotate, and therefore, the problems that the hydrofoil must be immersed for a certain depth for guaranteeing that the hydrofoil can not come out of water in the wave and wing movement amplitude is reduced exponentially along with the increase of the immersion depth can be solved.

Description

technical field [0001] The invention relates to the field of new wave propulsion for ships, in particular to a novel wave propulsion device with adjustable pitch, retractable floats and series trapezoidal wings. Background technique [0002] With the mandatory implementation of EEDI, newly designed ships whose EEDI index exceeds the standard will not be able to pass the audit of classification societies or IMO. Nowadays, the concept of "green ship" has been paid more and more attention by people, and the pace of development of green ship technology has been accelerated. , to promote the research and development of renewable clean energy. 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 a...
