一种定压采水器
本技术涉及海洋观测领域,尤其涉及一种定压采水器。
技术介绍
获取指定深度的海水样品在海洋调查中是一项最基本的工作,研究人员通常采用各种采水器来实现。如今国内的采水器一部分是采用矢锤击发的采水器,另一部分是由国外引进的大型CTD及其配套的玫瑰采水器。普通采用矢锤击发的采水器通过所释放缆绳长度来确定采水器深度,虽然价格低廉,但是操作复杂、受外界条件影响大,难以做到准确的定深定压采水;大型CTD和玫瑰采水器的组合可以很好的实现准确的定压采水,但是设备体积庞大,单套设备成本在80到100万人民币之间,并不适合大范围推广,并且因为体积过大难以在近海、湖泊、水库等环境进行采水。以上两种采水器前者价格低廉但是采水深度的准确度不高,受外界条件影响大,后者价钱昂贵体积较大,难以在近海、湖泊、水库中,进行采水。
技术实现思路
本技术要解决的技术问题是提供一种根据对压力的调节控制来实现对水深的控制,从而达到精确采集指定水深水样目的的定压采水器,其价格较为低廉、实用性强、应用范围广,可满足海洋、湖泊、水库等水质样品采集工作。本技术所采用的技术方案是:一种定压采水器,包括采水本体、 ...
