Abstract
The invention relates to a ship lifting machine operation controlling method and device, especially a hydraulic floating type ship lifting machine operation docking controlling method and device, The invention is characterized in that: an ancillary filling valve and an ancillary emptying valve are respectively connected in parallel with the main filling valve and the main emptying valve of the hydraulic floating type ship lifting machine water carriage system pipeline; the main filling valve and the main emptying valve are larger than the corresponding ancillary filling valve and ancillary emptying valve; regulating the opening of the small sized ancillary filling/emptying valve can control the ship lift chamber to enter and exit from the chamber pool; the big sized main filling/emptying valve is only opened before the ship lift chamber enters or after the ship lift chamber exits completely to increase the running speed of the ship lift chamber in air.
Description
Technical field
The present invention relates to a kind of ship elevator control method and device thereof, specifically hydraulic-floating ship elevator butt joint control method and device thereof.
Background technology
The hydraulic-floating ship lift be a kind of can serve as the ship lift pattern that drives power with water, it mainly controls by adjusting flow size in the water delivery main line that the ship reception chamber of ship lift goes out that entry, ship railway carriage or compartment are accurately docked, the operation problems such as balance adjustment before the release of ship railway carriage or compartment.Traditional hydraulic-floating ship elevator butt-joint control device as shown in Figure 1,2 arrange single (or a plurality of same size in parallel) water-filling valve 3 and emptying valves 4 on the water-main road, control the operation problems such as balanced adjustment that ship reception chamber 1 Water Exit, ship reception chamber 1 accurately docks, ship reception chamber 1 release is front that uninterrupted in the hydraulic pipeline 2 is controlled ship lift by the aperture size of adjusting single valve (water-filling valve 3 and emptying valve 4).Because water-main road 2 sizes are bigger, the interior flow velocity of pipeline is higher, and (diameter as Jinghong ship lift valve section is 2.5m, and Peak Flow Rate has reached 15m/s.), accurately dock in the operation realization ship railway carriage or compartment that will accurately control ship lift ship railway carriage or compartment, need carry out frequent accurately adjustment to the aperture of water-filling valve 3 and emptying valve 4, and the small action error of the valve of large scale, high flow rate all can cause the great changes of flow, and it is very big directly to realize that by the large scale valve low discharge of waterpower formula ship lift docking operation is accurately controlled difficulty.
Summary of the invention
Technical problem to be solved by this invention is: for the shortcoming that above prior art exists, propose a kind of hydraulic-floating ship elevator docking control method and the device thereof that can simple, safe and reliablely accurately control.
The technical scheme that the present invention solves above technical problem is:
Hydraulic-floating ship elevator docks control method, comprises that ship reception chamber rising operation is accurately docked and ship reception chamber decline moves accurately butt joint,
The accurate docking of ship reception chamber rising operation is carried out according to the following steps: (1) opens auxiliary drain valve; (2) judge whether ship reception chamber speed satisfies the water outlet rate request, if, then carry out next step, if not, then return previous step, adjust auxiliary drain valve aperture; (3) keep auxiliary drain valve aperture, make the ship reception chamber water outlet; (4) judge whether water outlet of ship reception chamber, if, then carry out next step, if not, then return previous step; (5) open main drain valve; (6) judge whether ship reception chamber speed meets design requirement, if, then carry out next step, if not, then return previous step, adjust main drain valve aperture; (7) keep main drain valve aperture and auxiliary drain valve aperture, make upwards operation of ship reception chamber; (8) close main drain valve, under auxiliary drain valve effect, make ship reception chamber low speed near docking location; (9) close auxiliary drain valve to little aperture, make ship reception chamber begin to dock with minimum speed and upstream; (10) judge whether ship reception chamber aligns with the upstream, if, then close auxiliary drain valve, if not, then return previous step, so that ship reception chamber docks successfully with the upstream;
The accurate docking of ship reception chamber decline operation is carried out according to the following steps: (1) opens auxiliary filling valve to standard-sized sheet; (2) open main filling valve; (3) judge the requirement that whether outpaces of ship reception chamber speed, if, then carry out next step, if not, then return previous step, adjust main filling valve aperture; (4) keep main filling valve aperture and auxiliary filling valve aperture, ship reception chamber is moved downwards; (5) close main filling valve, judge whether ship reception chamber satisfies the digging water speed requirement, if, then carry out next step, if not, then return previous step; (6) under auxiliary filling valve effect, the entry of ship reception chamber low velocity; (7) close auxiliary filling valve to little aperture, make ship reception chamber begin to dock with minimum speed and downstream; (8) judge whether ship reception chamber aligns with the downstream, if, then close auxiliary filling valve, if not, then return previous step, so that ship reception chamber docks successfully with the downstream.
The hydraulic-floating ship elevator butt-joint control device comprises main water-filling valve and main emptying valve, at least one auxiliary water-filling valve in parallel on main water-filling valve, at least one auxiliary emptying valve in parallel on main emptying valve.Main fill that (letting out) penstock place can be parallel with a plurality of different sizes fill (letting out) penstock, and fill (letting out) penstock aperture and control come in and go out pond, ship railway carriage or compartment or realize that the ship railway carriage or compartment docks with water levels of upstream and downstream, ship lift ship railway carriage or compartment by adjusting small size.
The size (flow) of auxiliary water-filling valve is less than the size (flow) of main water-filling valve, and the size (flow) of auxiliary emptying valve is less than the size (flow) of main emptying valve.
Only (after the complete water outlet of the ship reception chamber) unlatching before ship reception chamber begins entry of large-sized main water-filling valve and main emptying valve is to improve ship railway carriage or compartment speed of service in air.When rising operation on the ship lift ship railway carriage or compartment before the complete water outlet of ship reception chamber, large-sized main emptying valve is closed fully, go out water speed by the aperture control ship reception chamber of adjusting auxiliary emptying valve, open main emptying valve after the complete water outlet of ship reception chamber and improve the ship reception chamber speed of service, ship reception chamber is prepared and is closed main emptying valve fully before dock the upstream, controls ship reception chamber and accurately docks with the upstream by adjusting auxiliary emptying valve aperture.When ship reception chamber descends operation, open earlier auxiliary water-filling valve, open main water-filling valve after ship reception chamber starts and improve the ship reception chamber speed of service, close main water-filling valve before the ship reception chamber entry fully, by controlling auxiliary water-filling valve opening control ship reception chamber digging water speed and docking with the accurate of the level of tail water.
Advantage of the present invention is: the present invention can overcome the deficiency that existing hydraulic-floating ship lift adopts single large scale valve control ship elevator and accurately docking aspect of ship reception chamber, solve ship booster supporting compartment accurately docking and ship reception chamber operation control problem by undersized auxiliary filling (letting out) penstock, can be simple, safety, reliably hydraulic-floating ship elevator and docking are accurately controlled.
