Hydraulic gravity force type vertical ship lift
The invention relates to a waterpower gravity type vertical ship lift. A ship chamber and a gravity water chamber are caused to be in butted joint by an assembly pulley and a steel cable winding system of a wound roll in the way of bilateral balance so as to cause the lifting points of the ship chamber and the gravity water chamber to be in mutual rigid connection, thereby benefiting the maintenance of favorable synchronization during up and down running. When the ship chamber needs to be descended, water in the gravity water chamber is discharged; and when the ship chamber needs to be lifted, water is added to the gravity water chamber. By changing the gravity difference of counterpoise on both sides, the abrasion resisting moment of the steel cable winding system is overcome, thereby causing a ship reception chamber to be moved up and down and realizing the navigable butted joint of upstream and downstream water levels. A method for adding water to the gravity water chamber is as follows: by enlarging the area of a feed water inlet, the flow of the water is decelerated, and the mode of multi-layer water supply is adopted so as to reduce the water supply drop height of the feed water inlet and the gravity water chamber. The water flows out from overflow pore plates of a water storage chamber in a way of overflow and then flows downwards into the gravity water chamber along water curtain wall plates.

A structure for use in a body of water has at least one level that includes a boat lift, a narrow dock, or a larger entertainment area, or combinations of these items on multi-level structures (e.g. a boat lift on a first level and an entertainment area on a second level). The structure can be towed to or from a body of water independently of other structures. The structure includes a buoyancy system, e.g. at least one ballast tank or inflatable bladder, for allowing the structure to float in a buoyant state or to sink in a non-buoyant state into engagement with a bottom of the body of water. One or more structures such as these can be assembled to form an artificial breakwater by placing a wall or skirt on the windward side(s) thereof with each wall or skirt extending from below to significantly above the waterline. This forms a calmer area of water on the leeward side(s) thereof. In addition, an opposing wall or skirt can be placed on opposite sides of the structures to form a bounded chamber beneath the structure. A water recirculating device is used to pull up warmer water from near the bottom of the body of water and to discharge this warmer water into the bounded chamber and / or a water heating device is provided in the bounded chamber. This helps keep the structure sufficiently ice free to permit year round use if so desired even in northern climates.
