文档介绍：海洋微生物原位采样与分析装置的机械手
【设计总说明】
目前,海水内含微生物的数量及种类检测的主要手段是利用采样船采集水样,然后将水样在实验室中由专门的检测人员处理,利用各种相互独立的检测仪器检测水样中的微生物成分。这样的检测手段劳动强度大、耗时长、效率低,达不到对海洋环境微生物实时快速分析、监测与预报的要求。因此,研制一种海洋微生物的原位采样与分析装置已成为提高海洋环境预报能力的迫切需求。通常需要在海上,收集样本归还给实验室设备齐全个人分析。减少时间和成本,环境样品处理器(ESP)原位采样与分析装置是构建海洋环境微生物快速预警与监测网络的核心装备。

Marine anisms in situ sampling and analysis device of mechanical hand
【General Specification】
At present, the number and variety of seawater with anism detection is the primary means of using the sampling vessel for collecting water samples, and then the water in the laboratory detected by specialized personnel processing, using a variety of independent detection apparatus for detecting water samples in the position. Such a detection means great labor intensity, time consuming, low efficiency, not on marine environmental microbial rapid and real-time analysis, monitoring and forecasting demand. Therefore, to develop a kind of marine anisms in situ sampling and analyzing device has e to improve marine environmental forecasting ability is the urgent demand. Usually required in the sea, collection of samples returned to the laboratory equipment personal analysis. Reduce the time and cost, environment sample processor ( ESP ) in situ sampling and analyzing device is the construction of the marine environment of rapid microbial early warning andmonitoring of work equipment.
The design of mechanical hand the design specification for clamp, a telescopic arm, a stepping motor control system design thought and the design process. The content mainly includes: the holder and the telescopic arm of the whole scheme, using the electric drive system, there are electrical AC stepping motor, inverter and other ponents, corresponding to the motor selection and calculation, the overall structural
