Orbit-controlled angle-of-attack vibrating wing wind energy and tidal current energy conversion device

Abstract

The invention provides a vibration wing wind energy and tidal current energy conversion device with tracks controlling an attack angle. The vibration wing wind energy and tidal current energy conversion device with the tracks controlling the attack angle comprises supporting frames, oval attach angle control tracks, linear guide rails, vanes, attach angle control rods, connecting rods, crankshafts and wheel discs, wherein the linear guide rails are fixedly installed on the supporting frames, the two ends of each vane are embedded into the guide rails through a bearing and a sliding block, and the two ends of each connecting rod are hinged to a vane rotary shaft and a crank of the crankshaft or edge supporting points of the wheel discs respectively. Each crankshaft is connected with a transmission main shaft and is installed on the supporting frames through bearings. One end of each attack angle control rod is perpendicularly and fixedly connected with the corresponding vane rotary shaft in the chordwise direction, the other end of each attack angle control rod is embedded in a guide wheel of an oval control track disc and is provided with a mass block, the wheel discs are installed at the two ends of each crankshaft respectively, and end wing plates are installed at the two ends of each vane. Three or more vanes are adopted, the projections of the crankshafts connected with the vanes on the plane of a transmission main shaft disc are evenly distributed, and therefore the purpose of continuous and stable operation of the vibration wing wind energy and tidal current energy conversion device with the tracks controlling the attack angle is achieved. The vibration wing wind energy and tidal current energy conversion device with the tracks controlling the attack angle is high in energy efficiency, and can be applied to the fields of wind power generation and tidal current energy generation on the lands or near shores.

Description

technical field [0001] The invention relates to a power generation device, specifically a device for generating electricity by utilizing wind energy and tidal current energy. Background technique [0002] Wind energy and tidal current energy are excellent renewable energy sources that are clean and pollution-free. The development and utilization of wind energy and tidal current energy are important supplements to energy demand, and efficient and stable wind energy and tidal current energy conversion devices are the core key technologies for wind and tidal current energy generation. [0003] The current mainstream wind energy / tidal current energy generation devices can be roughly divided into horizontal axis type and vertical axis type. Most of them use the lift force received by the blades to drive the motor to generate electricity by arranging the blades. However, these two types of power generation devices still have their own technical advantages and disadvantages more ...
