Abstract

本实用新型公开了一种发电设备,具体是适用于风力发电的对转风力发电机。其主轴(1)装置在内转子(2)内中部,内转子(2)由两个第一轴承(3)装置在外转子(4)内中部,内转子扇翅(6)装置在主轴(1)上端;外转子(4)由两个第二轴承(5)装置在外壳(8)内部,外转子扇翅(7)装置在外转子(4)上端。由于本实用新型设计了内转子与外转子反向相互转动,采用新颖扇翅,能自动追踪风向,使内外转子不停的转动,大大增加了发电量,提高了发电效率,且具有稳定性好,可靠性高的特点。

Description

对转风力发电机技术领域:本实用新型涉及一种发电设备,具体是适用于风力发电的对转 风力发电机。背景技术:原风力发电机的定子是固定的,只有转子转动,从而使发电量 大大减少且发电效率低。实用新型内容:本实用新型克服了原定向风力发电机的弊端,提供了一种 增加发电量,提高发电效率的对转风力发电机。其主轴l装置在内转子2内中 部,内转子2由两个第一轴承3装置在外转子4内中部,内转子扇翅6装置在 主轴l上端;外转子4由两个第二轴承5装置在外壳8内部,外转子扇翅7装 置在外转子4上端。由于本实用新型设计了内转子与外转子反向相互转动,釆 用新颖扇翅,能自动追踪风向,使内外转子不停的转动,其转动的速度约是定 向风力发电机(定子和转子结构)相对速度及二者之间的切割磁力线的二倍, 发电量和发电效率是定向风力发电机(定子和转子结构)的三倍多,且具有稳 定性好,可靠性高的特点。附图说明:图l是本实用新型的主剖视图。 图2是图1的俯视图具体实施方式;如图1图2所示,主轴1装置在内转子2内中部,内转子2 由两个第一轴承3装置在外转子4内中部,其主轴l和内转子2应在一条轴线 上及保持同心度;内转子扇翅6装置在主轴1上端,并应和主轴l保持垂直度。 外转子4由两个第二轴承5装置在外壳8内部,并应和内转子2在一条轴线上及保持同心度;外转子扇翅7装置在外转子4上端,并应和外转子4保持垂直 度。内转子2和外转子4都是由矽钢片迭压并缠绕铜芯漆包线而成。如图1图2所示,内转子扇翅6与外转子扇翅7截面的形状呈半圆环,轮 廓分为凹面和凸面,且内转子扇翅6和外转子扇翅7扇翅轮廓的凹面与凸面相 反。因此,来自同一方向的风力推动扇翅的凹面的力大于推动扇翅凸面的力, 使内转子扇翅与外转子扇翅转向相反。同时当扇翅水平放置的时候,来自任何 方向的风都会推动扇翅转动。

Claims (2)
