Embodiment Construction

[0010] Below in conjunction with accompanying drawing, the present invention will be further described:

[0011] attached figure 1 , figure 2 It is an embodiment of the present invention, the impeller 10, the volute 11, the current collector 3 and the wind direction control rudder 2 of the volute type vertical axis wind power generator are installed on the frame 7, and the transmission 5 and the power generator are installed under the frame 7. Machine 6 and electric energy storage output device 8, and frame 7 is fixed with fixed steel cable 9 oblique pulls. The B-direction airflow enters the airflow passage in the volute 11 through the current collector 3, the impeller 10 of the wind-driven generator is installed in the volute 11, and the airflow entering the volute passage is used to drive all the blades of the wind-driven generator impeller 10. The impeller 10 of the generator drives the wind generator 6 through the transmission 5 to generate electricity, and the generate...

Abstract

The invention relates to a vertical-axis wind turbine, specifically to a vertical-axis wind turbine in which a wind turbine impeller 10 is mounted within a volute 11; the exterior of an airflow channel inside the volute 11 is connected to a windward current collector 3 that can enlarge windward area, all the airflows of windward face are converged to the airflow channel inside the volute 11, the airflows in the airflow channel inside the volute 11 are used for driving all the blades of the wind turbine impeller 10 so that driving torque of the wind turbine is much higher than that of general vertical-axis wind turbine, and meanwhile, requirement of start-up wind speed of the wind turbine are greatly reduced, the start-up wind speed is lower than 2m/s and coefficient of utilization of wind energy is raised to above 0.8, thus realizing maximization of the efficiency of the wind turbine.

Description

technical field [0001] The invention relates to a vertical axis wind power generator, in particular to a vertical axis wind power generator in which the impeller of the wind power generator is installed in a volute. Background technique [0002] Existing wind power generators are basically divided into two types: horizontal axis and vertical axis. The wind power generators currently used all have wind energy utilization coefficients within 0.5, and there is a problem of low efficiency. [0003] In the existing technology, most of the horizontal axis wind turbines are impellers with three blades, and the actual wind energy utilization coefficient is only 0.3-0.5; Various shapes of blade shapes, blade angle changes and various windshields are used to improve the wind energy utilization factor. Contents of the invention [0004] The purpose of the present invention is to reduce the resistance of the impeller of the vertical axis wind power generator and improve the wind ener...
