Description

technical field [0001] The invention discloses a device for efficiently capturing and utilizing ocean current energy. Background technique [0002] The current energy harvesting device can be mainly divided into four structural forms: horizontal axis current energy turbine, vertical axis current energy turbine, lift-resistance type current energy device, and oscillating hydrofoil current energy device. The conversion efficiency of the horizontal axis current energy turbine is not high. When the ocean current velocity is small, the power generation efficiency is relatively low; the vertical axis current energy turbine usually has poor starting performance and low efficiency, and it will be subjected to periodic loads; the lift-resistance type ocean current energy device Adding the dome also increases the engineering volume of underwater installation and recovery; the force of the oscillating hydrofoil of the oscillating ocean current power generation device is determined by m...
