Description

TECHNICAL AREA

The present invention relates to a stop log gate for chamber draining, overtaking, water blocking and flushing for a lock chamber and a drainage method.

STATE OF THE ART

In the multi-stage lock chamber, the primary lock chamber is drained and overhauled. In addition to closing the mortise gates, it is also necessary to lay a variety of stoplog gates to safely block the water. After completion of the overhaul, the lock chamber is filled with water. Because the water drop is too high, a reverse arch gate cannot be used to fill with water. Currently, water filling is carried out between the stop log gates, i.e. the top stop log gate is lifted off by a crane at a certain distance, creating a gap to fill with water. Thus, the speed and flow rate of the water are poorly controlled. Filling with water with a high water fall will damage the base plate of the lock chamber and endanger the crane system and the driver.

CONTENT OF THE PRESENT INVENTION

The main technical problem to be solved by the present invention is therefore to provide a stop log gate for chamber draining, overtaking, water blockage and flushing for a lock chamber and a drainage method, which can effectively reduce the adverse effects of water filling with a high water head on the bottom plate of the lock chamber.

To solve this problem, the invention creates the following technical solutions: A stop log gate for chamber emptying, overtaking, water blockages and flushing for a lock chamber, comprising gate slots and a base plate inserted into the gate slots, several flaps and a cover plate, wherein between the base plate, several flaps and sealing disks are arranged on the cover plate, with both ends of the flaps being fixedly connected to curved tubes, the upper ends of which communicate with a first inlet hole and a first drain hole inside the flaps, respectively, with between two adjacent flaps the first inlet hole on one of the flaps having communicating with the first vent hole at the other of the flaps, the first inlet hole, the first outlet hole and the curved tubes being connected in a curved flow channel, a second vent hole being provided inside the bottom panel, an end of the second vent hole being labeled e communicates in a lower end of the curved flow channel and another end of the second drain hole communicates with a non-water surface of the bottom plate, wherein a second inlet hole is provided inside the top plate, one end of the second inlet hole communicating with an upper end of the curved Flow channel communicates and another end of the second inlet hole communicates with a water-facing surface of the top plate, wherein a valve is provided inside the second inlet hole.

The valve includes a cylinder attached to the top plate and a valve hole provided in the top plate, the valve hole intersecting the second inlet hole, a piston disposed in the valve hole and communicating with the cylinder.

On the surface of the flaps facing the water, a plurality of limiting tubes are attached, with a rubber bladder being provided inside each of the limiting tubes, with the rubber bladder being connected to a buoy by a hose.

A shut-off valve and a pressure gauge are attached to the hose.

A method of dewatering a lock chamber using a stop log gate for chamber draining, overtaking, water blockage and flushing for a lock chamber, wherein after opening the valve, the water in the forward lock chamber is drained through the second inlet hole, the curved flow channel and the second drain hole into the rear lock chamber , when the water level in the rear sluice chamber rises to more than half the height of the bottom plate and the respective rubber bladders are filled with water, the respective flaps being pulled up by the rubber bladders, and the water in the front sluice chamber through a gap between the Flaps and the flaps or a gap between the flaps and the bottom plate flows into the rear lock chamber.

The advantageous effect of the invention is that by changing the water charge with a high water head of the rear lock chamber by a low water charge and by slowing down the water flow rate through the curved flow channel, there is an impingement of the water flow with a high water head on the bottom plate of the rear lock chamber can be severely weakened. By raising the flaps by the bladder, the water flow is filled from the bottom into the aft lock chamber, which on the one hand increases the speed of the aft lock chamber and on the other hand dampens the water entry into the water flow through the water in the aft lock chamber. At the same time, the vertical impact of the water flow on the bottom of the rear lock chamber is replaced by the water flow entering the rear lock chamber horizontally, thereby weakening the impact of the water flow on the bottom of the rear lock chamber.

DETAILED DESCRIPTION

Stop log gate for chamber emptying, overtaking, water blockages and flushing for a lock chamber, comprising gate slots 1 and a base plate 5 inserted into the gate slots 1, several flaps 3 and a cover plate 2, with sealing washers being arranged between the base plate 5, several flaps 3 and the cover plate 2 , wherein at both ends of the flaps 3 U-shaped curved tubes 4 are fixedly connected, the upper ends of which communicate with a first inlet hole 16 and a first drain hole 17 inside the flaps 3, respectively, with between two adjacent flaps 3 the first inlet hole 16 on one of the flaps 3 communicates with the first discharge hole 17 on the other of the flaps 3, the first inlet hole 16, the first outlet hole 17 and the curved tubes 4 being connected in a curved flow channel, with inside the bottom panel 5 a second Drain hole 18 is provided, one end of the second drain hole 18 having a lower end e of the curved flow channel and another end of the second drain hole 18 communicates with a non-water surface of the bottom plate 5, wherein a second inlet hole 15 is provided inside the top plate 2, one end of the second inlet hole 15 communicating with an upper end of the curved flow channel communicates and another end of the second inlet hole 15 communicates with a water-facing surface of the top plate 2, inside the second inlet hole 15 a valve is provided.

The valve can be opened when water in the front sluice chamber needs to be drained into the rear sluice chamber. The water in the front sluice chamber flows through the second inlet hole 15 and the curved flow channel, and is drained into the rear sluice chamber through the second drain hole 18, thereby changing the water charge with a high water head of the rear sluice chamber with a low water charge and reducing the water flow rate through the curved flow channel is slowed down, with an impact of the water flow with a high water head on the bottom plate 5 of the rear lock chamber is greatly weakened.

In order to lift the flaps 3, a hoisting rope can be tied to the two curved tubes 4.

The valve comprises a cylinder 12 attached to the cover plate 2 and a valve hole 13 provided in the cover plate 2, which valve hole intersects the second inlet hole 15, a piston 14 is disposed in the valve hole 13 and communicates with the cylinder 12.

The cylinder 12 drives the piston 14 to open and close the second intake hole 15 quickly and easily while the valve hole 13 moves.

A plurality of limiting tubes 7 are attached to the surface of the flaps 3 facing the water, a rubber bladder 8 being provided inside each of the limiting tubes 7 , the rubber bladder 8 being connected to a buoy 6 by a hose 11 . After switching on the hose 11 with the gas source, the compressed air enters the rubber bladder 8. The inflated rubber bladder 8 generates a lifting force to lift the flaps 3 and the top panel 2 so as to form a gap between the flaps 3 and the bottom panel 5 or between the flaps 3 and the flaps 3 . The water in the front lock chamber 20 quickly enters the rear lock chamber 19 through the gap, so that the rear lock chamber 19 is filled quickly. At the same time, the vertical impact of the water flow on the bottom of the rear sluice chamber is replaced by the water flow entering the rear sluice chamber 19 horizontally, and thereby the impact of the water flow on the bottom of the rear sluice chamber 5 is weakened.

A shut-off valve 9 and a manometer 10 are attached to the hose 11 . As in 2 As shown, the inflation of the bladder 8 can be determined during inflation of each bladder 8 by observing the manometer 10 to adjust the buoyancy of the bladder 8 and adjust the gap between the flaps 3 and the bottom panel 5.

Method of draining a sluice chamber using a stop log gate for chamber draining, overtaking, water blockages and flushing for a sluice chamber, wherein after opening the valve the water in the forward sluice chamber flows through the second inlet hole 15, the curved flow channel and the second drain hole 18 into the rear sluice chamber is discharged when the water level in the rear lock chamber rises to more than half the height of the bottom plate 5 and the respective rubber bladders 8 are filled with water, with the respective flaps 3 being pulled up by the rubber bladder 8 and the water in the front one lock chamber flows through a gap between the flaps 3 and the flaps 3 or a gap between the flaps 3 and the bottom plate 5 into the water level in the rear lock chamber 19, thereby preventing inflowing water flow from hitting the bottom of the rear lock chamber directly.
