Embodiment Construction

[0020] As shown in Fig. 1, the present invention is a fan blade structure and a speed-stabilizing device specially designed for vertical-axis movable blade wind turbines. Several small wind blade frames 2 are housed in each large wind blade frame 1, and the small wind blade frame shaft 5 is connected with the large wind blade frame 1 on the upper and lower sides of a mullion on the outside of the small wind blade frame 2 away from the main shaft 9 of the wind turbine. The inner side of the small fan blade frame 2 facing the wind-receiving facade is provided with movable small blades 3 and is connected with the small fan blade frame 2 with the second small shaft on the upper and lower sides of the inside of the vertical frame, and the movable small blades 3 can be wound around The second small axial small blade frame 2 rotates towards the inside of the wind-receiving facade to form the open and closed states of the wind blades. The small wind blade frame 2 is provided with a sup...

Abstract

One kind of vertical shaft-blade wind motor includes blades, vertical shaft and speed stabilizing mechanisms. The blade consists of large blade frame and small blade frames mounted on the large blade frame via movable shaft. The speed stabilizing mechanism mounted between each small blade frame and the large blade to start the rotation of the small blade frame relatively to the large blade frame and around the shaft. The present invention has effectively raised wind energy utilizing efficiency of wind motor, and in case that the wind speed exceeds the rated value, the speed stabilizing mechanisms will alter the position of the blades to penetrate wind to reach the speed reducing and stabilizing effect. The present invention adopts two or many layer serial large blade frame structure to raise wind driving efficiency and makes it possible to realize large wind motor system.

Description

technical field [0001] The invention belongs to a novel fan blade structure and a speed stabilizing device with the function of fan automatic protection on a vertical axis movable fan blade wind power engine. Background technique [0002] At present, there are two main types of wind power engines used for wind power generation or mechanical power in the world: one is the lift type, with a horizontal axis structure, using propeller blades; the other is drag type, with a vertical axis structure, using sail type blades . Compared with these two types of wind turbines, the lift type (horizontal axis) technology is more mature and widely used, but it has high costs, the blades are prone to fatigue damage, and the installation and maintenance of power generation equipment is inconvenient. It is necessary to set up windward devices and other issues; while resistance type (vertical axis) wind turbines have the advantages of large rotational torque, convenient installation and maint...
