A marine unmanned vehicle sail propulsion device and retracting mechanism

Abstract

The invention discloses a sail propulsion device and a retracting mechanism for an unmanned marine vehicle, which includes four parts: a linkage retracting mechanism, a rotation angle adjustment mechanism, a sail, and a ballast keel, which are used to adjust the turning angle of the sail and realize the sail and the ballast keel. Toggles between expanded and collapsed states. In the unfolded state, the sail stands on the upper part of the aircraft along the Z axis and can rotate around the Z axis, and the ballast keels on both sides are closed under the hull; The sails are retracted to the middle and rear of the aircraft and parallel to the upper surface of the aircraft, and the ballast keels are placed on both sides of the aircraft and parallel to the XY plane. The device of the invention realizes the conversion of wind energy into the forward propulsion force of the marine unmanned aircraft, and at the same time prevents the aircraft from excessive heel angle and overturning during navigation; when the marine meteorological conditions are not suitable for using sails, the sails of the invention can The mechanism can realize the furling of the sail and protect the sail.

Description

technical field [0001] The invention belongs to the technical field of new marine unmanned vehicles, and in particular relates to a sail propulsion device and a retracting mechanism for carrying and using marine unmanned vehicles. Background technique [0002] With the pace of human exploration and ocean cognition developing from near seas to far seas, unmanned and intelligent observation and detection technology has become a research hotspot in the field of marine engineering technology. Self-sustainability puts forward higher requirements. At present, marine unmanned aerial vehicles usually meet the energy needs of the propulsion and electricity consumption of the aircraft with their own batteries and fuel. The limited energy capacity of its own has greatly restricted the endurance and self-sustainability of marine unmanned aerial vehicles, and at the same time restricted the long-term and large-scale use of unmanned aerial vehicles in the open sea. [0003] There is hug...

Problems solved by technology

However, the marine meteorological conditions are changeable, and due to the light weight and limited structural strength of the sails of unmanned vehicles, the sails often break and break under strong ocean wind conditions.
