2、投捞爪能否张开到位是影响投捞器投捞成功 率的关键因素。本课题对投捞器投捞爪和凸轮控制装置进行改进设计，在投堵塞器 的下入过程中，要确保投捞爪以及堵塞器完全收入投捞器的腔体内，不超过投捞器 本身的最大直径，取消了投捞接头处的扭簧结构，提高了投捞的可靠性。对凸轮的 外轮廓线进行改进，使得当凸轮转过一定角度后，投捞爪就能被释放，凸轮在下入 过程中也要收入投捞器的最大直径内，上提时凸轮顺时针转动，释放投捞爪，导向 爪的释放装置与投捞爪处的释放装置相似。把导向和投捞分工化，比传统投捞器导 向和投捞都由投捞爪来完成更可靠，提高投捞的合格率。 关键词关键词：偏心配水器； 投捞器；堵塞器； II Abstra
