Abstract

本实用新型涉及一种风力发电机，其特征在于：支架上设有至少4片垂直于地面的风轮。使用时本实用新型的发电机设有垂直于地面的风轮，这种风力发电机无方向性，降低了启动风速，提高了发电机转速，继而提高了发电效率，同时风轮呈流线型，大大降低了迎风的噪声，达到了静音的效果。

Description

一种风力发电机
技术领域：
本实用新型涉及发电机的技术领域，具体地说是一种静音风力发电机。
背景技术：
现有的风力发电机往往采用水平装于地面的结构，这种风轮正面直接迎风，风轮受阻后变形旋转，因而在气流中旋转的风轮噪声很大，风轮的转速减慢，发电机发电效率低。
发明内容：
本实用新型的目的在于提供一种改进的风轮发电机，它可克服现有技术中风轮噪音大、发电机发电效率低的一些不足。
为了实现上述目的，本实用新型的技术方案是：一种风力发电机，它主要包括发电机组和设在发电机组上的支架，其特征在于：支架上设有至少4片垂直于地面的风轮。
使用时本实用新型的发电机设有垂直于地面的风轮，这种风力发电机无方向性，降低了启动风速，提高了发电机转速，继而提高了发电效率，同时风轮呈流线型，大大降低了迎风的噪声，达到了静音的效果。
附图说明：
图1为本实用新型一实施例的结构示意图
图2为本实用新型发电机组的结构示意图
具体实施方式：
下面结合附图和实施例对本实用新型作进一步的描述。
本实用新型主要包括发电机组1和设在发电机组上的支架2，其特征在于：支架上设有至少4片垂直于地面的风轮4，发电机组是由发电机7、发电机轴5和离合器6依次连接而成的，离合器外设有风轮的支架轮毂8，支架轮毂上设有至少8根支架，每两根支架上设有一风轮，风轮通过支架和支架轮毂连接到离合器，再经离合器连接到增速器和发电机，风轮呈流线型，每片风轮之间的夹角相等，绕着发电机组等距分布，这种流线型风轮大大降低了迎风噪声。
在实施中，发电机组设在风力发电机的立杆3上，采用5个风轮垂直安装在支架上，风轮、支架和支架轮毂均采用轻型材料制作而成的，在低风速时也能旋转发电，同时360度的任意风向均能使风轮受到风力而旋转，这种风力发电机无方向性，降低了启动风速(约在2m/s风速启动)，提高了发电机转速，发电效率提高了18-20％。
