In view of the key problem of subminiature underwater robots, structural improving,control algorithm and underwater experiment is studied. They can be described as follow: Firstly, the subminiature underwater robot should be compact in size and low cost, for which, it is difficult for us to control its balance. So that, a new kind of piston--style ups and downs system was invented, which can keep the underwater robot horizontally suspended in the water without driving force.

中文摘要本文针对超小型水下机器人在运动中存在的问题，设计了一种新的超小型水下机器人的沉浮结构形式，着重研究了其运动学动力学性能、探讨了相应控制算法、进行了水下试验，具体研究内容如下：首先，超小型水下机器人由于体积小重量轻，在水中沉浮时悬停平衡控制困难，为此进行了一种新的活塞式沉浮系统设计，该系统使水下机器人能够在无动力驱动的情况下，使其呈水平状态稳定悬浮在水中。

The differences is indeed that the source or power was the water-wheel, while in the prime motors of Europe, the force of steam was applied to the piston, but otherwise the set-ups were morphologically the same.

差别只在动力来源不同：中国是用水轮驱动，欧洲的原始发动机则以蒸汽力作用于活塞。至于结构方面，其形态大致相同。

The paper attempts to design and development a new type of hydraulic pump. It is the design of combining the advantages of sucker rod pump and rodless botttom hole pump, without pumping rod,and depends on the hydraulic system on the ground providing the impetus. The paper uses the pump Swabbing Principle to design the main parts of the pump structure and size, analyses and calculates the up down stroke of the piston and the switching process of pump valve, uses the finite element method to analyse the main force summing element and check intensity, and designs a ground hydraulic control system to match it. Considering the need of deep mining, salvage equipment is designed. The design shows that there is feasible and reliable to realize the exploitation underground using the new hydraulic pump. The design idea in this paper enlightens the rodless botttom hole pump production in the future and other similar issues.

本文尝试一种新型液力泵的设计和开发，它的设计思想是结合有杆泵和无杆泵各自的优点，取消抽油杆，依靠地面液压系统提供动力，本文从抽油泵抽汲原理出发，设计了抽油泵主要部件的结构和尺寸，对上下冲程柱塞的运动规律和泵阀启闭过程进行分析和计算，使用有限元法对主要零件进行了受力分析和强度校核，并设计与之配套使用的地面液压控制系统，考虑深井开采的需要，一并设计了打捞装置，为理论上实现了这种新型液力抽油泵井下开采的可行性和可靠性做了一些基础的工作，本文的设计思路对今后无杆泵采油等类似问题的研究做了有益的尝试。
