Description

Technical Field

[0001] The invention patent relates to the field of wave energy power generation technology, specifically a body-mounted wave energy power generation device used in unmanned ships. Background Art

[0002] As intelligent water equipment, unmanned ships have the advantage of breaking through the limitations of time, weather and environment in terms of patrolling waters, underwater detection, water rescue, and remote operations compared to traditional manned ships. At present, unmanned ships mainly use disposable batteries, batteries and fuel cells. Due to the space and weight limitations of the ship, the above-mentioned power supply methods can only provide short-term power supply for the ship. In the process of offshore operations, unmanned ships will face problems such as difficulty in replenishment and high costs, which limits the operation level and endurance of unmanned ships. Although waves are just the ups and downs of fluid particles in place, they contain huge energy. It is estimated that the wave energy on one square kilometer of sea surface can be as high as 250,000 kilowatts. Therefore, as long as wave energy is used properly, it can effectively solve the energy shortage problem faced by unmanned ships when operating in the open sea. In order to solve the above problems and realize "sea energy use, local energy acquisition", it is necessary to develop a sustainable wave energy generation technology with on-board power supply according to the characteristics of the unmanned ship itself. Using the structure of the unmanned ship itself to generate wave energy on-board power is one of the effective ways to solve the energy supply of unmanned ships in the future. Summary of the invention

[0003] Unmanned ships need to operate in the deep sea away from land. Electric energy is the basis for supporting the long-term stable operation of the power system of unmanned ships and many electronic instruments and equipment on board in the open sea. At present, unmanned ships mainly use disposable batteries, storage batteries and fuel cells. Due to the space and weight limitations of the ship, the above-mentioned power supply methods can only provide short-term power supply for the ship, thus limiting the operation level and endurance of the unmanned ship. Wave energy has the advantages of high energy density, wide distribution range and easy acquisition. Combined with the structural characteristics of the unmanned ship itself, the use of waves and the movement of the unmanned ship in the waves to provide electricity for the unmanned ship can effectively solve the problem of energy shortage of unmanned ships in the deep sea.

When the hull is in the sailing state, the side hatch is closed, and the float mechanism is extended into the hull cabin under the drive of the driving cylinder to reduce the resistance of the unmanned boat when sailing. A fan-shaped inertial rotor generator with an angle of 75° is installed at the bottom of the cabin below the water surface. When the hull is in the sailing or positioning state, the inertial rotor can rotate depending on the roll and pitch of the unmanned boat to drive the generator to generate electricity; the control mechanism is used to adjust the motor damping to optimize the power generation efficiency, rectify the output power of the motor, and control the expansion and contraction of the float mechanism.

The fan-shaped inertial rotor generator is composed of a fan-shaped inertial rotor, a generator, and a connecting shaft, and a circular protective panel is installed on the periphery of the fan-shaped inertial rotor. When the hull is in a navigation or positioning state, the inertial rotor can rely on the roll and pitch of the unmanned ship itself to rotate, thereby driving the generator to generate electricity. The power generation mechanism is a low-speed AC motor, which converts mechanical energy into electrical energy under the drive of the inertial rotor;

[0009] The intelligent multi-modal wave energy power generation resistance reduction and range extension device applied to unmanned ships is characterized in that: with the unmanned ship as the carrier, in the upper deck cabin located at the bow of the unmanned ship, the float power generation device is symmetrically installed in the side cabins of the hull, the bottom of the side cabin is above the waterline position, and has a certain slope to the outside to prevent water accumulation in the cabin bottom; when the unmanned ship is in the positioning state, the side hatch is opened, the float mechanism is extended under the drive of the rotating motor, the float contacts the water surface, the wave energy drives the float swing arm to swing continuously, and the generator is driven by the hydraulic cylinder and the hydraulic motor to generate electricity. When the hull is in the sailing state, the side hatch is closed, and the float mechanism is extended into the hull cabin under the drive of the rotating motor to reduce the resistance of the unmanned ship when sailing.

The pressure oil enters the accumulator through the first oil pipe 209, and then enters the hydraulic motor to drive the generator to generate electricity; when the hull is in a sailing state, the side hatch is closed, and the float mechanism is extended into the hull cabin under the drive of the driving cylinder; when the hull is in a positioning state, the side hatch is opened, and the float mechanism is extended into the hull cabin under the drive of the driving cylinder, and the float contacts the water surface.

The acceleration of the inertial rotor is collected by the acceleration sensor and transmitted to the PLC. When the acceleration is greater than the preset acceleration threshold, the resistance is adjusted to increase the damping of the generator, thereby reducing the movement speed of the inertial rotor, so that the movement of the inertial rotor remains relatively stable; vice versa. The controllable switch is used to control the extension and contraction of the float mechanism.
