Abstract

The invention discloses an ocean tidal current power generation system. The system comprises a supporting mechanism, an ocean tidal current power generator set and a signal monitoring mechanism. The supporting mechanism comprises a foundation pile, a horizontal supporting rod and an operating platform. The ocean tidal current power generator set comprises underwater components and an overwater component; each underwater component comprises blades, a hub, a spindle, a gearbox, a coupler, a power generator, a stern compartment and a yawing mechanism, wherein a variable propeller mechanism is arranged in the hub, and the yawing mechanism is arranged between the coupler and the horizontal supporting rod; the overwater component comprises a converter and a control cabinet, and the converter and the control cabinet are both arranged on the operating platform. The signal monitoring mechanism comprises a current meter connected with the control cabinet, and the current meter is arranged on the horizontal supporting rod and used for monitoring the ocean current direction in real time. The ocean tidal current power generation system has advantages that by adoption of the fixed ocean tidal current power generation system and the half-direct-driven wind power generator set, efficient conversion of ocean current energy into electric energy can be realized safely and reliably.

Description

technical field [0001] The invention relates to the technical field of ocean energy power generation, in particular to a fixed semi-direct drive ocean tidal current energy power generation system. Background technique [0002] Ocean tidal current energy is the kinetic energy contained in the tide water when it moves horizontally, also known as ocean current energy. Ocean currents are water masses of different densities formed by seawater in the ocean due to heat radiation, evaporation, precipitation, and cold shrinkage, plus wind stress, geostrophic deflection force, and tidal force. The ocean tidal current energy generation system uses the kinetic energy of the horizontal motion of the ocean current to generate and provide electrical energy through energy capture, energy conversion, and energy transmission. [0003] my country has abundant ocean tidal current energy resources, and the research and development of efficient and reliable ocean tidal current energy power gener...
