Sail propelling device and folding and unfolding mechanism of marine unmanned vehicle

Abstract

The invention discloses a sail propelling device and folding and unfolding mechanism of a marine unmanned vehicle. The sail propelling device and folding and unfolding mechanism comprises a linkage folding and unfolding mechanism, a corner adjusting mechanism, a sail and ballast keels, and is used for adjusting the sail corner of the sail and realizing the switching of the sail and the ballast keel between an unfolding state and a folding state. In the unfolding state, the sail stands on the upper portion of aircraft vehicle along a Z axis and can rotate around the Z axis, and the ballast keels on the two sides are folded below a hull. In the folding state, the linkage folding and unfolding mechanism and the corner adjusting mechanism are retracted into the vehicle, the sail is retracted to the rear middle portion of the vehicle and is parallel to the upper surface of the vehicle, and the ballast keels are arranged on the two sides of the vehicle respectively and are parallel to the XYplane. According to the device, wind energy is converted into an advancing propulsive force of the marine unmanned vehicle; meanwhile, the vehicle can be prevented from being overlarge in heeling angle and overturning in the navigation process; when the marine meteorological condition is not suitable for using the sail, the sail folding and unfolding mechanism can fold the sail to 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.
