Floating Vertical Axis Wave Power Plant

Abstract

The invention proposes a floating vertical-shaft wave power generation device, and belongs to the field of wave power generation. The floating vertical-shaft wave power generation device comprises a floating table, a support plate, a vertical pendulum, a shaft connection device, a power generator, a protection cover, a fixed anchoring chain, a direction limiter and a rolling device, wherein the support plate is fixed above the floating table, the protection cover is fixed below the floating table, the power generator is vertically fixed in the protection cover, a rotation shaft of the power generator vertically penetrates through the floating table and the support plate, the vertical pendulum is horizontally arranged on the support plate, is connected with the rotation shaft of the power generator via the shaft connection device and swings and rotates under a wave rising and falling effect, a rotor of the power generator is driven to rotate so as to further generate power, one end of the fixed anchoring chain is connected with the floating table, and the other end of the fixed anchoring chain is fixed at a seabed. With the adoption of a vertical-shaft structure, the application area of the power generation device is effectively reduced, the power generation efficiency of unit area is improved, the defect brought by a platform of conventional wave power generation fixed at the seabed is prevented, the floating vertical-shaft wave power generation device is applicable for offshore power generation and is also suitably used for building a central- and far-sea large-size wave power generation plant.

Description

technical field [0001] The invention relates to an ocean wave power generating device, in particular to a vertical axis ocean wave power generating device floating on the sea surface. It belongs to the field of wave power generation. Background technique [0002] With the trend of environmental degradation and fossil energy shortage becoming more and more obvious, people have gradually paid attention to the development and utilization of clean energy. Wave power generation is a means of effectively utilizing clean energy. In the wave power generation devices studied and applied at the present stage, the generators are all designed as long-axis horizontal generators, and generally all need to install special platforms on the seabed or in the sea to fix the generators, which results in limited offshore space. It is impossible to build such power generation devices on a large scale, which reduces the power generation per unit area and increases the cost of power generation. ...
