Description
Technical field
This utility model relates to a kind of Waterpower type ship elevator and method, a kind of band ship reception chamber self feed back stabilisation systems and have Waterpower type ship elevator and the method for resistance to capsizing, belongs to navigation building field.
Background technology
Waterpower type ship elevator is a kind of novel ship lift, number of patent application is: although the Chinese patent of 99116476.8 discloses the basic structure of a kind of Waterpower type ship elevator, that is: be respectively provided with in the lock chamber both sides accommodating ship reception chamber multiple separate with lock chamber and mutual connect fill, the vertical shaft discharged water, each vertical shaft arranges floating drum, multiple floating drums are by corresponding steel cable, reel, pulley position multiple with ship reception chamber is connected (i.e. forming multiple suspension centre on ship reception chamber), when vertical shaft water-filling, floating drum rises, ship reception chamber declines, otherwise ship reception chamber rises, thus complete hydro powered formula and rise ship or fall ship.But owing to not providing the technical scheme that can solve the problem that Waterpower type ship elevator ship reception chamber has antidumping under by unbalanced load situation, the most it is not promoted and applies.For wet type crosses dam class ship lift, owing to it is directly to inject water in ship reception chamber, berth in the water of ship reception chamber boats and ships again, roadster oceangoing ship is made together to rise with ship reception chamber or drop, therefore when ship reception chamber be in preferable level, i.e. ship reception chamber structure and equipment, water body loaded center of gravity is respectively positioned on the geometric center of ship reception chamber, and does not has the interference of external unbalanced load in running, when making water body keep absolute rest state, the problem that ship reception chamber does not haves inclination.But, in actual motion, ship reception chamber is inevitably affected by many unbalanced loads, and cause local buckling, cause water fluctuation in ship reception chamber, and then after causing ship reception chamber to occur, its interior water body of the ship reception chamber of inclination boosting again occurs bigger fluctuation, and make water body loaded center of gravity seriously offset, plus mobility and the characteristic that Water seeks its own level of water body, cause ship reception chamber to tilt and continue to amplify, the security incident of toppling after final initiation ship lift unstability.Therefore, if not solving Waterpower type ship elevator to ultimately result in the problem toppled because of local buckling, then Waterpower type ship elevator does not just have practical value.
Make a concrete analysis of as follows:
Ship reception chamber is anhydrous, and have water to distinguish the most intuitively from ship reception chamber be exactly that the load suffered by ship lift system is different, solves the ship reception chamber problem of toppling and first has to analyze after ship reception chamber loads water body, the impact that water body load brings to ship elevator.Under the anhydrous operating mode of ship reception chamber, no matter ship reception chamber is in inclination, is in level, and ship reception chamber structure and equipment loaded center of gravity are all without occurring great change, and the load that ship reception chamber acts on suspension centre is the most basically identical.Under ship reception chamber has the operating mode of water, when ship reception chamber is in preferable level, ship reception chamber structure and equipment, water body loaded center of gravity are in center, act on the load on each suspension centre equal；But when there is the state tilted in ship reception chamber, because the water body load of ship reception chamber there occurs skew, ship reception chamber structure and equipment, water body loaded center of gravity is caused all to change, the load that ship reception chamber acts on each suspension centre changes the most therewith, therefore having occurred as soon as the positive feedback phenomenon that ship reception chamber tilts, this is that the ship lift of all wire rope suspensionings all can problems faced.
Water is had to tilt positive feedback phenomenon in conjunction with ship reception chamber, ship reception chamber has water to understand with ship reception chamber anhydrous assay, under ship reception chamber has the operating mode of water, once there is less inclination in ship reception chamber, may result in water fluctuation in ship reception chamber, destroy the stress balance of each suspension centre of ship reception chamber, especially in the water body inclination that the generation of boosting ship reception chamber is bigger again in the case of height flowed toward lower moment, and then cause steel wire rope, synchronous shaft system is deformed, and work as steel wire rope, the gradient of ship reception chamber is increased the weight of the most in turn after synchronous shaft system deformation, so produce a ship reception chamber and deformed → increase the weight of, by force unbalance → hydraulic assist(ance) ship reception chamber inclination → steel wire rope/synchronous shaft system, the positive feedback phenomenon that ship reception chamber tilts, ultimately result in the problem that ship reception chamber has water to topple.
By above-mentioned analysis: under ship reception chamber has the operating mode of water, inevitably result from ship reception chamber, it is therefore necessary to study new technical scheme to solve the problem that ship booster supporting compartment has water to tilt.
