The invention provides an embedded-type passive self-winding-unwinding device for a wave propeller. The embedded-type passive self-winding-unwinding device for the wave propeller comprises a mass block arranged in a ship body, a spring, a reversing air room, an air storage device, a steel wire rope and a wave propeller winding-unwinding connecting rod. The ship body heaves and sinks caused by influence of waves, relative movement is generated between the mass block and the ship body. A power input rod which is connected with the mass block is pulled up and down. The reversing air room blows air to the air storage device. Air pressure of the air storage device is increased. A piston of the air storage device drives the steel wire rope which is connected with the piston, and then the wave propeller is driven to wind and unwind the connecting rod, so that the wave propeller overcomes the pull force of the spring to stretch below the water surface. When wave energy is decreased, the air pressure of the air storage device is decreased, the thrust of the steel wire rope is not enough to overcome the pull force of the spring, the steel wire rope is pulled back above the water surface, and recovery is completed. According to the embedded-type passive self-winding-unwinding device for the wave propeller, the passive self-winding-unwinding device is provided for the wave propeller of an unmanned ship, the energy is saved, the good marine environmental suitability is provided, and support is provided for running of long endurance of the unmanned ship.
Description
technical field [0001] The invention relates to the conversion and collection of wave energy, in particular to an embedded passive self-retractable device of a wave propeller. Background technique [0002] Wave energy is a renewable energy that is easily obtained at sea, and there are many ways to collect it at this stage. The wave-driven unmanned boat has been developed in recent years, and the unmanned boat is driven by the wave propeller under the hull, which has initially satisfied the maneuverability. [0003] For example, the patent number 201520183626.0 is named as a biplane wave-propelled remote unmanned boat, which provides a wave energy propulsion of the unmanned boat by using the propelling hydrofoils fixed on the bow and stern of the boat, which greatly improves the battery life of the unmanned boat. ability. The wave-propelled unmanned boat can effectively drive the unmanned boat to sail when the waves are sufficient, but in sea conditions where the wave energ...
