Vertical axis wind power generation and navigation aid wind energy utilization device without middle supporting shaft

Abstract

The invention relates to a vertical axis wind power generation and navigation aid wind energy utilization device without a middle supporting shaft. The vertical axis wind power generation and navigation aid wind energy utilization device comprises an upper end plate, a lower end plate, a wind turbine blade, a generator shell, an upper flange, a lower flange and a base; a plurality of first mounting connecting holes are formed in the middle positions of the upper end plate and the lower end plate at intervals, and a plurality of second mounting connecting holes are symmetrically formed in the edge positions of the upper end plate and the lower end plate; the first mounting connecting holes and the second mounting connecting holes are in one-to-one correspondence in the positions of the upper end plate and the lower end plate; the upper end and the lower end of the wind turbine blade are fixedly connected with mounting bolts for being fixedly mounted with the upper end plate and the lower end plate; a generator body is arranged in the generator shell, and the generator shell comprises a shell stator and a rotor shaft; the rotor shaft penetrates through the center of the generator body and extends out of the lower end of the generator shell; the upper flange is arranged at the top end of the generator shell; the lower flange is fixedly arranged at the lower end of the rotor shaft in a sleeving manner; the base is fixedly mounted on a ship; and the upper flange and the lower flange are fixedly connected with the lower end plate and the base correspondingly. The vertical axis wind power generation and navigation aid wind energy utilization device has the advantages of double wind energy utilization modes and high wind energy utilization rate.

Description

technical field [0001] The invention relates to the fields of wind power generation and sail navigation aid, in particular to a vertical axis wind power generation and navigation aid wind energy utilization device without an intermediate support shaft. Background technique [0002] When ships sail at sea, they need to consume a lot of fuel for power generation and navigation. The current international environmental protection regulations are becoming more and more stringent, and the requirements for energy efficiency, harmful gas emissions and greenhouse gas emissions of ships are getting higher and higher. Offshore wind energy for power generation and navigation aid will definitely reduce fuel consumption of ships and promote the application of clean energy in shipping. [0003] At present, research at home and abroad is mainly focused on ship wind power generation or ship sailing to aid navigation, without considering the effective combination of the two to improve the com...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a vertical axis wind power generation and navigation aid wind energy utilization device without an intermediate support shaft, by adopting a vertical axis wind turbine with variable blades and adjustable radius, and fully considering the different navigation conditions of ships, By changing the blades, the flexible composition can be used for both power generation and navigation aid dual-purpose wind energy utilization device. In particular, the device has no intermediate support shaft to interfere with the internal flow field of the wind rotor, which is conducive to deeper mechanism research , which solves the problems of the single mode of the existing wind energy utilization device, the low utilization rate of wind energy, and the interference of the intermediate support shaft on the internal flow field, etc.
