Abstract
The utility model discloses a wing type automatic-orientation vertical wind wheel device which comprises a plurality of leaf blades, a wind wheel bracket, a bearing and a vertical shaft. The leaf blades are provided with wing type cross sections, and are connected with the wind wheel bracket. The wind wheel bracket which is fixed by a wheel hub is connected with a wind wheel power generator systemby the bearing and the vertical shaft, drives a rare earth permanent-magnetic generator to carry out power generation by a wind wheel and to be controlled by a controller, and outputs electric energywhich is used by load. Each leaf blade of the wing type automatic-orientation vertical wind wheel device adopts the structure of the cross section of an airplane wing, and a plurality of wind wings are vertically combined. The force lifting direction of each wind wing is designed into the tangential direction, so as to lead low requirement for the starting wind speed of the wind wheel and high rotating efficiency, thereby not only solving the problem that the wind wheel cannot carry out automatic-orientation starting or low wind-speed starting, but also increasing the power efficiency of thesystem.
Description
Technical field
The utility model relates to the wind wheel field of wind-driven generator, relates in particular to a kind of rotational efficienty and the high wind wheel apparatus of stability.
Background technique
Present wind turbines rotor device adopts eight or five fan blades, and its leaf cross-section is flat face or curved surface.But not aircraft airfoil section structure.The sub-wind wheel structure of also employing that has to drive big wind wheel according to wind direction and rotates.Existing wind turbines rotor device is not because blade adopts streamlined type design, and wherein the wind wheel apparatus windage loss of resistance type is big; The wind wheel apparatus of lift formula, its blade lift direction not on tangent line and angle of lift excessive, cause wind power conversion efficiency low, equipment requires highly to starting wind speed, can't work under gentle breeze; And low from directed ability, when wind direction was disorderly, wind wheel may not change.
Summary of the invention
The utility model embodiment provides a kind of wing blade automatic orientation vertical wind wheel apparatus, and under breeze conditions, wind wheel can both start by automatic orientation, and unidirectional stable rotation, has improved the power factor of device, has reduced manufacturing and mounting hardness.
The utility model embodiment provides a kind of wing blade automatic orientation vertical wind wheel apparatus, comprise that multi-disc has the blade of wing blade cross section, wind wheel support, bearing and vertical shaft, the wind wheel support that is connected with described blade is fixed by wheel hub, be connected with the wind wheel generator system with vertical shaft by bearing, be sent to controller by the generating of wind wheel drive rare earth permanent-magnetic generator and control the electric energy that output loading is used.
Further, described blade has adopted aircraft wing type cross section design, and the actual lift direction that makes each blade is for being the tangent direction of the slewing circle in the center of circle with the vertical shaft center line.
Further, described wind wheel is crossed the wind wheel support by orthogonal four or five blade pass and is composed of a fixed connection with quadrangle or pentagonal wheel hub, makes that under any wind direction condition wind wheel can both unidirectional stable rotation.
Further, the pressure center point position of described blade is according to the adjustment that is complementary of the position of the size of blade incidence, the string of a musical instrument, and blade has been selected the wing shape of aircraft for use, when wind wheel rotates, it can not be subjected to because of distortion changes efficient, guarantees the vane aerodynamic maximization.
The vertical wind wheel apparatus of wing blade automatic orientation that the utility model provides, the blade of wind wheel, promptly the wind wing adopts the aircraft wing cross-sectional structure, windy wing combination.And the lift direction that designs each wind wing is for being the tangent direction of the slewing circle in the center of circle with the vertical shaft center line, it is low to make wind wheel start the wind speed requirement, the rotational efficienty height, solved the problem that wind wheel can not directedly voluntarily start or low wind speed starts, improved the power factor of system, made the output power of main air wheel in very wide wind speed range, reach specified output.
Described wing blade automatic orientation wind wheel apparatus is simple in structure, and design science is reasonable, has reduced manufacture cost and mounting hardness.
