Embodiment Construction

[0009] Now refer to the attached figure 1 , 2 , 3, detailed description is as follows in conjunction with embodiment: column type multi-stage wind-driven generator of the present invention relates to two major components of wind-driven generator and upright blade paddle, specifically comprises: frame 1, blade paddle A2, It consists of blade B3, generator stator 4, generator rotor 5, rectifier, charger, storage battery and inverter. The so-called paddles, including paddle B3 and paddle A2, are two blades whose cross-sectional area is in the shape of a semicircle, and interact on a straight line on a plane, forming a hollow circle in the middle. It can be called a vertical paddle. The blades of each stage have the same structure and are 90 degrees from the center of the circle. The generator stator 4 is composed of a plurality of permanent magnets distributed discretely, and automatically forms a graded cutting magnetic field line motion according to the rotation speed of the...

Abstract

The invention relates to a columnar multistage aerogenerator, which comprises a stander, an impeller A, an impeller B, a generator stator, a generator rotor, a rectifier, a charger, a storage battery and an inverter. The impellers are two blades having semicircular sections, which are intercrossed on a straight line of one plane, have a hollow circle at center and are vertically arranged. The distance between the generator stator and the rotor is adjustable, so that the columnar multistage aerogenerator has the electricity generation efficiency of different levels without changing the structure of the aerogenerator. The center point of the stander is vertically provided with an impeller shaft, the impellers B and A are arranged on the impeller shaft in an interactive mode, the upper end of the impeller shaft is arranged at the center of the upper end of the stander, while the lower end is connected with the generator rotor. The columnar multistage aerogenerator is movable, is convenient to move, carry and mount, and can be mounted at any position and height.

Description

Technical field: [0001] The invention relates to a wind power generator, in particular to a cylindrical multi-stage wind power generator. Background technique: [0002] The conversion of wind energy into electrical energy, that is, the wind power conversion system, has reached the level of 1MW to 1.5MW in the field of industrial applications. The wind power generators in the prior art rely on facilities such as high towers and large blades in specific wind farms to obtain high wind speeds to generate electric energy, which is feasible in tuyere areas where there is wind all year round. However, the areas with downwind wind all year round are limited after all, and it is impossible to install and operate high towers in densely populated areas. Therefore, it is difficult to realize the civilian application of this wind power equipment characterized by high towers. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies of the prior a...
