Vertical offshore wind power generation device

Abstract

The invention discloses a vertical offshore wind power generation device, which relates to the field of offshore wind power generation, and is characterized in that the vertical offshore wind power generation device comprises a floating platform and a generator, and the floating platform is provided with a wind gathering device for converting transverse wind power on the sea surface into longitudinal wind power through a wind gathering pipeline; the air gathering device comprises an air funnel arranged on the floating platform in the vertical direction, an air gathering assembly which is arranged at the bottom of the air funnel and guides air into the air funnel through a pipeline, and a drainage assembly which is rotationally connected to the top of the air funnel, can rotate along with the air and can guide airflow in the air funnel to move upwards; and a power generation device capable of rotating under the action of longitudinal wind and transmitting kinetic energy to the generator is further arranged in the ventilation barrel, so that the technical effects that the power generation device only bears impact load of airflow in the vertical direction, the stress directions of the power generation device are more consistent, and a power generation part cannot be damaged due to acting force in multiple directions.

Description

technical field [0001] The invention relates to the field of offshore wind power generation, in particular to a vertical offshore wind power generation device. Background technique [0002] With the advancement of society and the rapid improvement of the level of science and technology, people's demand for electricity is also constantly increasing. Conventional thermal power generation methods have gradually been unable to meet people's daily electricity needs, and also cause pollution to the environment. Therefore, there is a need for continuous pollution-free and sustainable supply of wind power technology. [0003] The principle of wind power is to drive the windmill impeller to rotate through the wind, and then make the generator generate electricity. Compared with wind power on land, wind energy resources on the ocean are abundant and stable, and will not interfere with human daily life. [0004] At present, in deep-sea wind power, wind power generation equipment is g...

AI Technical Summary

Problems solved by technology

[0004] At present, in deep-sea wind power, wind power generation equipment is generally installed on the floating platform, but when working, the floating platform will be affected by the wave and shake, and at the same time, the wind power generation device will shake, especially in the case of strong wind, the wave The impact force generated is relatively large, and the shaking of the floating platform is more severe. The windmill impeller of the wind power generation equipment is also affected by the shaking of the floating platform while rotating against the wind, so that the windmill impeller is subjected to both lateral impact load and longitudinal force. When the wind power cannot be used, it will cause the windmill impeller to be twisted and deformed, resulting in damage
