Double-buoyancy-body pendulum type bidirectional turbine wave power generation device

Abstract

The invention belongs to the technical field of energy development, and relates to a power generation device for converting ocean wave energy to power, in particular to a double-buoyancy-body pendulum type bidirectional turbine wave power generation device. The double-buoyancy-body pendulum type bidirectional turbine wave power generation device mainly consists of a base, a buoyancy pendulum supporting structure and a self-variable pitch horizontal-shaft tidal current energy power generator, wherein the tidal current energy power generator and a buoyancy pendulum reciprocally swing under the action of waves; during the process, a tidal current energy turbine absorbs the energy of incoming flows in two directions through rotating towards the same direction and changing the pitch, so that the efficiency of the complete machine is improved greatly; since an inflation-deflation valve is installed on the buoyancy pendulum, the posture of a power generation system can be adjusted for the lifting completion of the unit; and therefore, when the maximum wave energy on the sea surface is obtained, the whole machine simultaneously can sink into the sea so as not to be damaged by a disaster. The double-buoyancy-body pendulum type bidirectional turbine wave power generation device is simple in structure and easy to repair; and in addition, the technical difficulties such as excessive energy consumption and unavailable long-term reliable operation resulting from the three-level energy conversion of the traditional pendulum type power generation device are solved.

Description

technical field [0001] The invention belongs to the technical field of energy development, and relates to a power generation device for converting ocean wave energy into electric energy. [0002] Background technique [0002] With the outbreak of the worldwide energy crisis and the urgency of accomplishing the goal of energy saving and emission reduction, all countries have increased the development and utilization of clean energy. In particular, the development and utilization of ocean energy has been increased, among which wave energy has become a hot spot in ocean energy research and development due to its large reserves and wide distribution. In the past 30 years, more than 30 wave energy demonstration power generation devices have been built in the world, but there are still The goal of commercial utilization has not been achieved because of the harsh marine environment and the failure to make breakthroughs in key technologies, which have resulted in the inability of ...
