A device for efficiently capturing and utilizing ocean current energy

Abstract

The invention discloses a device for efficiently capturing and utilizing ocean current energy, which comprises a box, and two diversion covers are installed on the top of the box to realize collection, acceleration and guidance of ocean currents; A plurality of movable blades, the bottom of each movable blade is connected with a blade bracket, each blade bracket is connected with a bushing, each bushing is set on two guide wheel shafts, and a guide wheel is installed at both ends of each guide wheel shaft , the guide wheel can move circularly along the circular guide track, all the bushings are fixedly connected with the same belt, the belt is driven to rotate by the movement of the movable blade, the belt drives the pulley to rotate, and the pulley Then, it is connected with the generator through the speed-increasing mechanism to realize the collection and conversion of ocean current energy.

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-drag 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 current velocity is small, the power generation efficiency is relatively low; the vertical axis current energy turbine usually has poor starting performance, low efficiency, and is subject to periodic loads; lift-drag type current energy device The addition of the shroud also increases the amount of subsea installation and recovery; the force on the oscillating hydrofoil of the oscillating ocean current energy power generation device is determined by multiple parameters, the control process ...
