Wave energy power generation device

Abstract

The invention discloses a wave energy power generation device. The wave energy power generation device comprises a sealing outer shell, and an overall motion unit, a direct-current motor II and a geararranged in the sealing outer shell; the overall motion unit is radially limited in the sealing outer shell, and can move up and down; the overall motion unit comprises an inner shell, a direct-current motor I, an eccentric wheel, a first main shaft, a second main shaft and a rack; the direct-current motor I, the inner shell and the second main shaft are arranged from top to bottom; the eccentricwheel is positioned in the inner shell, and is mounted on the first main shaft; an output shaft of the direct-current motor I is connected with the first main shaft; the upper end of the second mainshaft is fixed at the lower end of the inner shell; the rack is arranged at the lower part of the second main shaft; the gear is engaged with the rack; the gear is arranged on an output shaft of the direct-current motor II; when waves drive the sealing outer shell to move, the sealing outer shell and the overall motion unit are relatively displaced to urge the eccentric wheel to rotate around thefirst main shaft so as to drive the direct-current motor I to generate electricity; and through engagement between the gear and the rack, the direct-current motor II is driven to generate the electricity.

Description

technical field [0001] The invention belongs to the field of new energy and energy collection, and more specifically relates to a wave energy generating device, which can collect ocean wave energy and improve energy collection efficiency. . Background technique [0002] Like tidal energy, ocean temperature difference energy, salt gradient energy, and ocean current energy, ocean energy is one of the most abundant, common, and difficult-to-use resources in ocean energy. Wave energy is an ocean energy that accounts for a large proportion of ocean energy. The wave motion of sea water produces wave power to generate very huge energy. It is estimated that the wave energy in the world's oceans reaches 70 billion kilowatts, accounting for 94% of all ocean energy, and it is the "first household" among all kinds of ocean energy. Waves are one of the forms of movement of seawater, and their generation is the result of the joint action of external forces (such as wind, changes in atm...
