Problems solved by technology

This results in high cost of power generation
At the same time, it is not suitable for the energy raising method with low energy density of waves
In the existing wave power generation device, its power generation system or energy raising system is in direct contact with seawater, and its survivability is poor due to reasons such as corrosion, marine biological pollution, and damage from extreme sea conditions.
Due to the low energy efficiency and the unsteady power output of the power generation system, the power quality produced by existing wave power generation devices is poor
Based on the above problems, most of the existing wave power generation devices are difficult to achieve commercial operation

Abstract

The invention relates to a resonant type wave power generating device which comprises a hull, a controlled energy-improving device and a generating device. The resonant type wave power generating device is characterized in that the controlled energy-improving device is composed of a gravity balancer, a rigidity regulating system and a swinging body, wherein the swinging body and the hull can move relatively driven by ocean wave so that the ocean wave energy can be extracted and then converted to mechanical vibration energy; the gravity balancer comprises a bracket, a swinging arm, an elastic mechanism and a track; the rigidity regulating system comprises a rigidity transfer mechanism and a variable-rigidity device, when the swinging body and the hull are in the relative motion, the rigidity regulating system can provide torsional rigidity together with a gear seat so as to form a vibration energy-absorbing system; the natural vibration period of a vibration system can be changed by regulating the rigidity of the variable-rigidity device, so that the rigidity of the variable-rigidity device can be in line with the period of ocean wave and the vibration system can realize resonance impelled by ocean wave, thus the highest energy-absorbing efficiency can be realized.

Description

technical field [0001] The invention aims at extracting the energy of sea waves to realize power generation. Ocean waves exist as waves whose energy consists of kinetic energy and potential energy. The kinetic energy of a wave refers to the energy of the wave moving forward, and the potential energy refers to the energy of the wave rising and falling. The kinetic and potential energies of waves are equal. According to the characteristics of ocean waves, the most direct way to extract energy from ocean waves is to use vibration to increase energy. The wave energy is extracted through vibration, converted into mechanical energy, and then converted into hydraulic energy, and the hydraulic energy drives the hydraulic motor and then drives the generator to generate electricity. Thereby realizing wave power generation using ocean waves. Background technique [0002] The energy reserves of ocean waves are large, and they are clean, renewable, inexhaustible, and do not occupy l...
