Abstract

The invention relates to a vertical axis wind generator, in particular to an improvement on the structure of the vertical axis wind generator. The invention aims to provide the vertical axis wind generator with a simple structure and stable output power. The invention comprises a tower. The key points of the structure of wind generator are that a stator which is provided with a primary winding and a secondary winding is horizontally fixed on the vertical axis above the tower; a permanent magnet is arranged inside a housing rotor corresponding to the primary winding and the secondary winding of the stator; vanes are arranged outside the housing rotor; and the parts where the housing rotor is contacted with the vertical axis and the tower are respectively provided with a shaft.

Description

Technical field: [0001] The invention relates to the improvement of the structure of the vertical axis wind power generation device. Background technique: [0002] Existing wind power generation devices are usually arranged on the turntable of the tower, and its main structure is that the blades are connected with the generator through a gear box and a brake device. But there are the following disadvantages: the speed ratio of the gear box is large, the frequency of power generation is unstable; the power generation device is bulky and heavy; maintenance is also difficult. Invention content: [0003] The present invention aims at the above problems and provides a vertical axis wind power generation device with simple structure and stable output power. [0004] In order to achieve the above object, the present invention adopts the following technical solutions. The present invention includes a tower, and the main points of its structure are fixed horizontally on the vertic...
