Problems solved by technology

Because it is generally believed that the tip speed ratio of vertical axis wind turbines cannot be greater than 1, and the wind energy utilization rate is lower than that of horizontal axis wind turbines, vertical axis wind turbines have not been valued for a long time.

Embodiment Construction

[0012] refer to figure 2 , the invention points out the process flow path for preparing multiple sets of fan impellers. Specifically, the helical blades 3 that assemble at least two hubs are prepared in order, at least two keel frames 5 are prepared, and at least two or more fasteners 7 are prepared; one end of the blade 3 is installed on the The blade positioning groove 6 of the hub 4 is locked with a fastener 7, and then the other end of the blade is connected with the keel frame 5 and locked with a fastener 6 to complete the assembly of one set of impellers, and then assemble the other in the same way. A group of impellers, after that, adjust the gap between each blade so that it is between 0.01 and 1.77 centimeters and make the spacing even; then each group of impellers is assembled on a shaft 4 concentrically and coaxially (hub The hole position is coaxial with the generator), at this time, the shape of the blades of each set of impellers assembled should be stacked rel...

Abstract

The invention relates to a method for preparing multiple sets of impellers of a wind power generator, comprising the steps of: preparing at least two helical blades equipped with hubs, preparing at least two keel frames, and preparing at least two or more fasteners; One end of the blade is installed in the blade positioning groove of the hub and locked with a fastener, and the other end is connected with the keel frame and locked with a fastener to complete the assembly of one set of impellers, and assemble another set of impellers in the same way, and then , adjust the gap between each blade so that it is between 0.01 and 1.77 cm and make it evenly spaced; assemble each group of impellers on the same shaft according to concentricity and coaxiality, and the blades in each group are relatively the same The shafts are stacked and rotated 180° from top to bottom to surround the shafts, and the distance between each impeller group is between 0.02 and 2 cm.

Description

technical field [0001] The invention relates to a method for preparing an impeller of a power generation device in the field of wind power generation, in particular to a method for preparing multiple groups of impellers for a wind power generator. Background technique [0002] Human beings have used wind energy for thousands of years. Before the invention of the steam engine, wind energy was used as an important driving force and applied to many aspects of human life. The exploration of wind power generation originated in Denmark at the end of the 19th century, but until the 1970s, only small-scale charging wind generators reached the practical stage. From the outbreak of the oil crisis in 1973 to today's society, developed countries such as the United States and Western Europe have invested a lot of money in seeking energy alternatives to petroleum fuels, mobilizing high-tech industries, and using new technologies in the fields of computers, aerodynamics, structural mechani...
