Combined power generation device based on ocean wave energy and tidal energy

Abstract

The invention discloses a combined power generation device based on ocean wave energy and tidal energy, and relates to the technical field of new energy power generation. The device comprises a fixedframe, and the peripheral side face of the fixed frame is sleeved with a lifting plate; the upper surface of the lifting plate is rotationally connected with a first overturning frame and a second overturning frame; the peripheral side face of the first overturning frame is sleeved with a rotating sleeve cooperating with an engaged toothed bar; and ratchet bars engaged with the first overturning frame are arranged in the rotating sleeve in an annular array manner. According to the device, the lifting plate moves downwards along the fixed frame under the action of a floating block, the liftingplate drives the first overturning frame to rotate under the action of a ratchet wheel, the rotating sleeve and the ratchet bars to achieve tidal energy power generation while moving downwards, the first overturning frame rotates under the impact of waves, meanwhile, the waves impact on the coast or a dam body to splash, the second overturning frame rotates, wave energy is effectively collected and converted, and the generating capacity and the energy efficiency of ocean energy power generation are improved.

Description

technical field [0001] The invention belongs to the technical field of new energy power generation, in particular to a combined power generation device based on ocean wave energy and tidal energy. Background technique [0002] The use of ocean energy is the direction of energy research in the world today. Especially in the situation where energy is related to national security, the earth's mineral energy is gradually depleted and the environmental situation is deteriorating, how to effectively use the abundant and renewable marine resources is very important. [0003] Chinese patent CN202300819U (application number: 201120451088.0) discloses a "tidal energy and wave energy power generation device", and its embodiment includes a device that can be placed on the lake surface, reservoir surface or sea surface and is limited by the anti-drifting mechanism and can fluctuate with the water level. A floating body that moves up and down; a toothed straight guide rail that is fixed ...
