Abstract

本实用新型涉及一种防爆型潜水电机。包括电机壳、接线盒盖、电缆线、电机引出线,其特征在于:在电机壳与接线盒盖之间有防爆端盖,防爆端盖有上、下两个碗状腔体组成,上碗状腔体的顶部与接线盒盖相联,下碗状腔体的下部与电机壳相联,在防爆端盖上有接线柱,接线柱贯穿于防爆端盖,电机引出线与接线柱的下端连接,电缆线与接线柱的上端联接。上碗状腔体的顶部与接线盒盖相联处有O形密封圈,下碗状腔体的下部与电机壳相联处有O形密封圈。接线柱由螺纹与防爆端盖上的螺纹孔连接。本实用新型的优点是能够防止普通型潜水电机在水中使用时水从接线盒中渗入电机内,同时也能够防止电缆线和电机引出线的接线处产生电火花而引爆易燃易爆气体。

Description

防爆型潜水电机
技术领域
本实用新型涉及一种潜水电机,特别是一种防爆型潜水电机。
背景技术
目前现有的普通型潜水电机接线盒盖与机壳之间只有一道O形圈密封,机壳与接线盒盖之间的接线腔空间很小,电缆线在接线腔内与电机引出线直接联接,如遇有易燃易爆混合气体,接线腔内产生的电火花就会引爆易燃易爆气体,所以现有的普通型潜水电机接线盒只能用于一般性的无需隔爆的场合,不能满足既有易燃易爆混合气体又需要使用潜水电机的场合的需求。
发明内容
本实用新型的目的是解决现有技术中普通型潜水电机接线盒盖所存在的问题,提供一种接线盒密闭效能好的防爆型潜水电机。本实用新型设计防爆型潜水电机,包括电机壳、接线盒盖、电缆线、电机引出线,其特征在于:在电机壳与接线盒盖之间有防爆端盖,防爆端盖有上、下两个碗状腔体组成,上碗状腔体的顶部与接线盒盖相联,下碗状腔体的下部与电机壳相联,在防爆端盖上有接线柱,接线柱贯穿于防爆端盖,接线柱的上端位于上碗状腔体内,接线柱的下端位于下碗状腔体内,电机引出线与接线柱的下端连接,电缆线与接线柱的上端联接。上碗状腔体的顶部与接线盒盖相联处有O形密封圈,下碗状腔体的下部与电机壳相联处有O形密封圈。接线柱由螺纹与防爆端盖上的螺纹孔连接。本实用新型的优点是能够防止普通型潜水电机在水中使用时水从接线盒中渗入电机内,同时也能够防止电缆线和电机引出线的接线处产生电火花而引爆易燃易爆气体。
附图说明
下面结合附图和实施例对本实用新型作详细说明,
附图为本实用新型的结构示意图,
具体实施方式
图中包括电机壳1、接线盒盖2、电缆线3、电机引出线4,其特征在于:在电机壳1与接线盒盖2之间有防爆端盖11,防爆端盖11有上、下两个碗状腔体5、6组成,上碗状腔体5的顶部与接线盒盖2相联,下碗状腔体6的下部与电机壳1相联,在防爆端盖11上有接线柱7,接线柱7贯穿于防爆端盖11,接线柱7的上端位于上碗状腔体5内,接线柱7的下端位于下碗状腔体6内,电机引出线4与接线柱7的下端连接,电缆线3与接线柱7的上端联接。上碗状腔体5的顶部与接线盒盖2相联处有O形密封圈8,下碗状腔体7的下部与电机壳1相联处有O形密封圈9。接线柱7由螺纹与防爆端盖11上的螺纹孔10连接。由于防爆端盖11有上、下两个碗状腔体5、6组成,它隔离了外界的空气与接线处的连接,因此能够防止引爆外界的易燃易爆气体。
