Vertical shaft wind motor three-halberd vortex-eliminating windwheel

Abstract

The invention discloses a three-halberd vortex elimination wind wheel for a vertical shaft wind motor, wherein, the structure of a three-bladed closed cavity is formed by enclosure of vane plates on three side faces and three-halberd cover plates on the top and at the bottom; a vane plate is an S-shaped circular arc column panel which is formed by smooth connection of two sections of circular arc column panels the arc roofs of which face to opposite directions; air flow slots are uniformly distributed on one section of the circular arc column panel along the height direction; two outer ends of various vane plates are respectively provided with butt-joint arc cylinders which are mutually butted; arcs on both sides of various halberd arms of the three-halberd cover plates on the top and the bottom of the wind wheel respectively are matched with and correspond to arcs of the two sections of circular arc column panels of the vane plates; head peripheral surfaces of various halberd arms of the halberd arm shaped cover plates form circular curved surfaces which correspond to the butt-joint circular cylinders of the vane plates. The wind wheel is characterized by low eddy loss, high power coefficient, simple structure, reliable operation, beautiful appearance and so on.

Description

technical field [0001] The invention belongs to the technical field of wind power engines, and relates to a three-half vortex-eliminating wind energy transmission wind wheel of a vertical axis wind power motor. Background technique [0002] Wind energy is a clean, safe and renewable green energy, and it has gradually become a new energy that is vigorously developed and utilized by countries all over the world. Wind turbines can be divided into two types: horizontal axis wind turbines and vertical suction wind turbines, and vertical axis wind turbines can be divided into lift wind turbines and drag wind turbines. The publication specification of the Chinese invention patent application with the application number 200610017530 discloses a three-blade wind energy transfer cavity wind wheel of a vertical axis wind power engine. The wind wheel belongs to the resistance type wind wheel, and its structure is Figure 7 As shown, it is formed by connecting S-shaped arc cylindrical bl...

The publication specification of the Chinese invention patent application with the application number 200610017530 discloses a three-blade wind energy transfer cavity wind wheel of a vertical axis wind power engine. The wind wheel belongs to the resistance type wind wheel, and its structure is Figure 7 As shown, it is formed by connecting S-shaped arc cylindrical blade plates 22 on three sides and upper and lower cover plates 21, and the middle part of the wind wheel is a three-leaf closed cavity surrounded by blade plates 22 and cover plates 21. In order to make the blade plate 21 of the impeller have a relatively large windward resistance surface, the outermost end of each blade plate 22 of the wind wheel has a circular arc column-shaped fan blade 23 extending out of the three-blade closed cavity, The central angle of the arc surface of the protruding fan blade 23 is 40°. Since the blade plates 1 on each side of the three-leaf closed cavity are provided with air flow passages, the three-bladed closed cavity of the impeller has an air flow channel. This wind wheel makes up for the deficiency of the large starting moment of the traditional Sabinius type wind wheel, and improves the power coefficient of wind energy utilization; When facing the wind, eddy currents will be generated in the concave cavity of the wind rotor that accepts wind energy, and the wind energy size entering the three-leaf closed transmission cavity will be reduced, so that the power of the wind rotor will be reduced; The column panel increases the manufacturing cost and assembly difficulty of the wind wheel
