Abstract

The invention discloses a crosswind type all-weather wind power generator and relates to the technical field of wind power generation equipment. A main shaft of the generator is vertically arranged and externally connected with an impeller; a plurality of windward boards are evenly distributed on the impeller and each windward board is provided with a window; one side of each window is connected with a vane through a torsion spring and a rotation shaft parallel to the main shaft of the generator; the main shaft of the generator is externally connected with a wind shield through a bearing and the wind shield covers outside a part of the impeller; and a guiding empennage is fixedly connected with the outer side of the wind shield. The invention has the advantages of good dynamic balance, small vibration, stable and reliable running and large output power, and can greatly reduce the basic production cost and normally work under the condition of heavy wind and even storm wind.

Description

technical field [0001] The invention relates to the technical field of wind power generation equipment. Background technique [0002] Wind power plays an important role in new energy and has been greatly developed in recent years, but some problems also restrict its further development due to existing wind power technology. The traditional wind turbine shaft is installed horizontally, and the wind acts on the three blades to generate driving force, which makes the horizontal shaft rotate. Due to the poor dynamic balance performance and serious vibration during operation, the iron tower foundation for installing the generator must be It is very large to overcome the problem of vibration, and the existing basic investment sometimes accounts for more than 50% of the total investment. Second, due to severe vibrations, the reliability of wind turbines is reduced and maintenance is frequent. Furthermore, when the wind is very strong, in order to avoid damage to the wind turbine,...
