Description

一种装配有防水保护罩的交流电机 技术领域
本实用新型属于交流电机领域，具体涉及一种装配有防水保护罩的交流电机。
背景技术
交流电机是用于实现机械能和交流电能相互转换的机械。由于交流电机功率的覆盖范围很大，因此常用于各种不同场合。在潮湿环境或者在雨水多的室外使用交流电机时，若交流电机未做防水处理，则水容易进入交流电机内部导致交流电机的损坏，因此需要对交流电机作防水处理。
现有的防水交流电机将外表的各个部件进行静密封处理，前后电机端盖和外壳均为无缝隙结构，缝隙处通过密封胶密封，具有较好的防水性能。但是这种防水交流电机若内部出现问题，修理较为麻烦，安装和拆卸都较为不便。
实用新型内容
本实用新型的目的是提供一种装配有防水保护罩的交流电机，防水保护罩拆卸和安装方便，同时防水性能好。
为了解决上述技术问题，本实用新型采用如下技术方案：
一种装配有防水保护罩的交流电机，交流电机安装在防水保护罩内，其特征在于：防水保护罩包括保护壳体、前遮板和后遮板，保护壳体固定于前遮板和后遮板内。防水保护罩分为三个部分围住整个交流电机，可避免外界的液体进入交流电机内，便于安装和拆卸。
进一步，保护壳体由上壳体和下壳体构成，上壳体设有凸起条，下壳体设有安装槽，凸起条与安装槽相匹配。上壳体和下壳体的设置便于交流电机的放入和取出，凸起条和安装槽便于上壳体和下壳体之间的安装。
进一步，安装槽周围设有防水条。防水条可以防止上壳体和下壳体之间的 间隙渗水，提高防水性能。
进一步，上壳体和下壳体的侧边均设有固定块，上壳体的固定块与下壳体的固定块之间通过螺杆和螺母固定。由于防水条在长时间使用后可能会发生形变，固定块可以压紧上壳体和下壳体，防止防水条出现缝隙。
进一步，下壳体的底部设有固定座，固定座包括底板和支撑板，下壳体固定在支撑板上。固定座用于支撑交流电机，提高交流电机的稳定性。
进一步，前遮板和后遮板之间固定有连接杆。连接杆加强前遮板和后遮板的稳定性，防止交流电机工作时由于震动导致前遮板和后遮板产生缝隙。
进一步，前遮板呈圆台状，前遮板的中心设有轴孔。交流电机工作时转轴转动，若有水喷射到前遮板时，水向外侧流动，防止水渗入交流电机内。
由于采用上述技术方案，本实用新型具有以下有益效果：
防水保护罩分为保护壳体、前遮板和后遮板三个部分围住整个交流电机，可避免外界的液体进入交流电机内，便于安装和拆卸。保护壳体分为上壳体和下壳体的设置便于交流电机的放入和取出，凸起条和安装槽便于上壳体和下壳体之间的安装。安装槽围有的防水条可以防止上壳体和下壳体之间的间隙渗水，提高防水性能。由于防水条在长时间使用后可能会发生形变，上壳体和下壳体设有的固定块可以压紧上壳体和下壳体，防止防水条出现缝隙。下壳体底部的固定座用于支撑交流电机，提高交流电机的稳定性。前遮板和后遮板之间的连接杆加强前遮板和后遮板的稳定性，防止交流电机工作时由于震动导致前遮板和后遮板产生缝隙。交流电机工作时转轴转动，若有水喷射到前遮板时，由于前遮板为圆台形，水向外侧流动，防止水渗入交流电机内。
附图说明
下面根据附图对本实用新型作进一步说明。
图1为本实用新型中一种装配有防水保护罩的交流电机的结构示意图；
图2为本实用新型中一种装配有防水保护罩的交流电机的爆炸图；
图3为图2中A处的放大示意图。
具体实施方式
如图1至图3所示的一种装配有防水保护罩的交流电机1，交流电机1安装在防水保护罩内，防水保护罩包括保护壳体、前遮板2和后遮板3，保护壳体固定于前遮板2和后遮板3内。前遮板2和后遮板3可以螺纹固定于保护壳体。防水保护罩分为三个部分围住整个交流电机1，可避免外界的液体进入交流电机1内，便于安装和拆卸。前遮板2和后遮板3与保护壳体之间的缝隙可以使用密封胶密封。
保护壳体由上壳体4和下壳体5构成，上壳体4设有凸起条6，下壳体5设有安装槽7，凸起条6与安装槽7相匹配。上壳体4和下壳体5的设置便于交流电机1的放入和取出，凸起条6和安装槽7便于上壳体4和下壳体5之间的安装。安装槽7周围设有防水条8。防水条8可以防止上壳体4和下壳体5之间的间隙渗水，提高防水性能。
上壳体4和下壳体5的侧边均设有固定块9，上壳体4的固定块9与下壳体5的固定块9之间通过螺杆和螺母固定。由于防水条8在长时间使用后可能会发生形变，固定块9可以压紧上壳体4和下壳体5，防止防水条8出现缝隙。下壳体5的底部设有固定座，固定座包括底板10和支撑板11，下壳体5固定在支撑板11上。固定座用于支撑交流电机1，提高交流电机1的稳定性。
前遮板2和后遮板3之间固定有连接杆12。连接杆12加强前遮板2和后遮板3的稳定性，防止交流电机1工作时由于震动导致前遮板2和后遮板3产生缝隙。前遮板2呈圆台状，前遮板2的中心设有轴孔13，交流电机1的转轴14贯穿轴孔13。交流电机1工作时转轴14转动，若有水喷射到前遮板2时，水向外侧流动，防止水渗入交流电机1内。
安装防水保护罩时，先将交流电机1放在下壳体5上，将上壳体4的凸起条6对准下壳体5的安装槽7，用螺杆和螺母固定上壳体4和下壳体5的固定块9。将前遮板2和后遮板3安装在保护壳体的前端和后端，最后将连接杆12螺栓固定于前遮板2和后遮板3之间，完成安装。
以上仅为本实用新型的具体实施例，但本实用新型的技术特征并不局限于 此。任何以本实用新型为基础，为解决基本相同的技术问题，实现基本相同的技术效果，所作出地简单变化、等同替换或者修饰等，皆涵盖于本实用新型的保护范围之中。
