The new unit adopts hollow sucker rod working with pump and as fluid passage instead of conventional sucker rod, and uses a new hanger to fix the one-piece barrel rod pump on the casing wall, improving the operation stability of the subsurface pump.

针对这种情况，大港油田新世纪机械制造有限公司研制成功一种新型无油管采油装置，这种装置以空心抽油杆代替实心抽油杆带泵工作并兼作出油流道，还通过一种新型悬挂器将整筒抽油泵固定在套管壁上，提高了抽油泵的工作稳定性。

In this design, according to the principle of crank-rocker, a special four-bar linkage swaying mechanism combined with the flexible tail fin is adopted to guarantee the stable swimming of robofish. The skillful application of hall position sensors achieves the detection of critical position of the swing link, which makes it possible to detect the position of the tail fin and control the turning of robofish. For effective raising and lowering, a mechanism using a cylinder as a pump to imitate the swimming bladder is developed.
