ABSTRACT:
An automatic level-control floating apparatus supports a pontoon bridge, a floating floor or another superstructure floating on the sea, where the height of tide or the sea level varies. It is difficult to maintain the level of such a superstructure, which the floating apparatus can keep at a constant level without using motive power.The floating apparatus includes a supporting tank3, which rests on the water bottom. The top of the supporting tank3is open to the atmosphere. A piston body1can reciprocate vertically in the supporting tank3. The apparatus also includes floating tanks2, which are integral with and positioned outside the piston body1. The tops of the floating tanks2are open to the atmosphere. The floating tanks2are floating on the water. A floating body4can move vertically in each floating tank2and supports the superstructure. The interior of each floating tank2and the interior of the supporting tank3are connected by an elastic or flexible communicating tube5, through which liquid can flow between them.
