Description

小型风力发电机浮动型集电环构件
技术领域
本实用新型涉及一种构件，特别是一种小型风力发电机浮动型集电环构件。
背景技术
现有小型发电机内的集电环与电刷都是固定接触，电刷是固定不动的，通过集电环的转动达到转向的目的。但此种结构存在以下缺点：结构不够合理，电刷与集电环接触面变动较大，产生的飞弧较强，增加了磨损，容易造成接触不良。
实用新型内容
本实用新型的目的在于提供一种结构合理，可减少电刷与集电环接触面的变动，从而减少了飞弧，延长了使用寿命的小型风力发电机浮动型集电环构件。
本实用新型的目的可以通过以下措施来达到：一种小型风力发电机浮动型集电环构件，包括电刷、弹簧、集电环，其特征在于：还有上刷架、下刷架，集电环夹装于上刷架与下刷架中间，上刷架与下刷架通过螺栓连接在一起，电刷及弹簧装于下刷架内，电刷与集电环接触。
本实用新型的目的还可以通过以下措施来达到：下刷架与盖板之间通过螺栓连接为一体，电刷及弹簧置于下刷架的空腔内。集电环包括环主体、接触片、导线，接触片设于环主体的对称面上，与电刷接触。
本实用新型相比现有技术具有如下优点：结构合理，可减少集电环与电刷接触面的变动，从而减少了飞弧，延长了使用寿命，保证接触良好。
附图说明
图1为本实用新型的正向剖视结构图；
图2为本实用新型的侧向剖视结构图。
具体实施方式
本实用新型下面将结合附图(实施例)作进一步详述：
参照图1、图2，本实用新型包括电刷1、弹簧2、集电环3、上刷架4、下刷架5、螺栓6、8，盖板7等。集电环3包括环主体3-1、接触片3-2、导线3-3。上刷架4及下刷架5呈近似的半圆弧状，并通过螺栓6组合为一体；集电环3夹装于上刷架4与下刷架5所形成的空腔内。盖板7盖于下刷架5底部，并通过螺栓8与其连接为一体；电刷1及弹簧2置于下刷架5的空腔5-1内。电刷1可与集电环3上的接触片3-2接触。在下刷架5的两侧还设有挡板(图中未画出)。当集电环3转动时(与风机转轴连动)，整个上刷架4、下刷架5、电刷1都会随之转动一定角度，当下刷架5被挡板挡住时，电刷1才与集电环3上的接触片3-2脱离接触。由于增加了这个转动角度，故减少了集电环3与电刷1接触面的变动，变成浮动型接触，故大大减少了飞弧，延长了整个构件的使用寿命。
