Deformable paddle mechanism of ocean current energy power generation set

Abstract

The invention relates to a deformable paddle mechanism of an ocean current energy power generation set. The deformable paddle mechanism comprises a paddle, wherein a trailing edge flap is hinged to the paddle, the trailing edge flap is connected to a push rod which drives the trailing edge flap to rotate in a hinged manner, the push rod is fixedly connected to a micro displacement amplifier, a stacked piezoelectric ceramic is fixedly mounted in the micro displacement amplifier, and the stacked piezoelectric ceramic is connected to a piezoelectric controller which outputs a voltage to the stacked piezoelectric ceramic. Different from a conventional variable pitch mechanism which controls the load by changing the pitch angle, the deformable paddle mechanism changes the hydrodynamic characteristics by controlling deviation of the trailing edge flap at the trailing edge of the paddle, thereby achieving the purpose of controlling the load.

Description

technical field [0001] The invention belongs to the field of ocean current energy power generation, and in particular relates to a deformable paddle mechanism of an ocean current energy generating set. Background technique [0002] Renewable energy comes from wind energy, solar energy, biomass energy, ocean energy, etc. Among them, ocean energy is rich, environmentally friendly, and clean, and has won the favor of researchers from all over the world. 71% of the earth's surface is covered by the ocean, which breeds huge ocean energy. Ocean energy has abundant energy reserves, and the available energy greatly exceeds the sum of the current global energy demand, and has the advantages of high density and predictability. [0003] In the design of ocean current energy generating units, the design of the turbine is particularly important, because how much power the final unit can generate depends on how much power the turbine can capture from the ocean current. Good hydrodynamic c...

Problems solved by technology

However, the traditional pitch control mechanism is still relatively complicated at present. The oil circuit of the hydraulic pitch control mechanism needs to be connected to the rear of the hub by the oil distribution mechanism. The installation accuracy is relatively high, and the reliability in the complex and changeable marine environment needs to be improved.
