Description
Water Retaining and Flushing Stoplog Gate for Lock Chamber Water-drained Overhauling, and Drainage Method
Technical Field
[0001] The present invention relates to a water retaining and flushing stoplog gate for lock chamber water-drained overhauling, and a drainage method.
Background Art
[0002] For first lock chamber water-drained overhauling of multi-level lock chambers, besides closing a miter gate, it is also necessary to arrange several stoplog gates upstream of the miter gate to realize reliable water retaining. After finishing the overhauling, the lock chamber is filled with water, and a reverse radial gate cannot be used for water filling due to an excessively high head. A measure adopted currently is to fill water between the stoplog gates, which means that an uppermost stoplog gate is lifted by a crane for a certain distance to form a gap for filling water, so that a water filling speed and a flow rate are not easy to control, and high-head water filling is easy to cause damage to a bottom plate of the lock chamber, so that a crane device and a crane driver are in danger.
Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a water retaining and flushing stoplog gate for lock chamber water-drained overhauling, and a drainage method, which can effectively alleviate adverse effects of high-head water filling on a bottom plate of a lock chamber [0004] In order to solve the above problem, the technical solution to be solved by the present invention is as follows.
A water retaining and flushing stoplog gate for lock chamber water-drained overhauling comprises a gate slot, and a bottom plate, a plurality of flashboards and a top plate which are inserted into the gate slot, and sealing gaskets are arranged among the bottom plate, the plurality of flashboards and the top plate, wherein two ends of the flashboard are fixedly connected with a curved pipe, upper ends of the curved pipe are respectively communicated with a first water intake hole and a first drainage hole arranged in the flashboard, for two adjacent flashboards, the first water intake hole in one flashboard is communicated with the first drainage hole in the other flashboard, and the first water intake holes, the first drainage holes and the curved pipes are connected to form a curved flow channel; a second drainage hole is arranged in the bottom plate, one end of the second drainage hole is communicated with a lower end of the curved flow channel, and the other end of the second drainage hole is
Description
communicated with a downstream face of the bottom plate, and a second water intake hole is arranged in the top plate, one end of the second water intake hole is communicated with an upper end of the curved flow channel, the other end of the second water intake hole is communicated with an upstream face of the top plate, and a valve is arranged in the second water intake hole.
[0005] The valve comprises a cylinder mounted on the top plate and a valve hole arranged in the top plate, the valve hole intersects with the second water intake hole, a plunger is arranged in the valve hole, and the plunger is communicated with the cylinder.
[0006] A plurality of limiting pipes are mounted on an upstream face of the flashboard, a rubber inflatable bag is arranged in each limiting pipe, and the rubber inflatable bag is connected with a buoy through a hose.
[0007] A stop valve and a pressure gauge are mounted on the hose.
[0008] In a drainage method for a lock chamber by the water retaining and flushing stoplog gate for lock chamber water-drained overhauling, after the valve is opened, water in a front lock chamber passes through the second water intake hole, the curved flow channel and the second drainage hole, and then is drained into a rear lock chamber; when a water level in the rear lock chamber rises to more than 1/2 height of the bottom plate, the rubber inflatable bags are inflated, the rubber inflatable bags drag the flashboards at all levels to move upwardly, and the water in the front lock chamber flows into the rear lock chamber through a gap between the flashboards or a gap between the flashboard and the bottom plate.
[0009] The present invention has the beneficial effects that: high-head water filling into the rear lock chamber is changed into low-position water filling, and the curved flow channel is used to slow down a water flow speed, thus greatly reducing an impact of a high-head water flow on the bottom plate of the rear lock chamber; in addition, after the rear lock chamber is filled with water of a certain depth, the inflatable bags hold up the flashboards, so that the water flow is filled into the rear lock chamber through a bottom portion, which increases a speed of the rear lock chamber on one hand, and buffers the filled water flow with the water in the rear lock chamber on the other hand; and meanwhile, the original vertical impact on the bottom portion of the rear lock chamber is changed into horizontally entering the lock chamber, thus further weakening the impact of the water flow on the bottom plate of the lock chamber.

Detailed Description of the Preferred Embodiments
[0012] A water retaining and flushing stoplog gate for lock chamber water-drained overhauling comprises a gate slot 1, and a bottom plate 5, a plurality of flashboards 3 and a top plate 2 which are inserted into the gate slot 1, and sealing gaskets are arranged among the bottom plate 5, the plurality of flashboards 3 and the top plate 2. Two ends of the flashboard 3 are fixedly connected with a U-shaped curved pipe 4, and upper ends of the curved pipe 4 are respectively communicated with a first water intake hole 16 and a first drainage hole 17 arranged in the flashboard 3. For two adjacent flashboards 3, the first water intake hole 16 in one flashboard 3 is communicated with the first drainage hole 17 in the other flashboard 3, and the first water intake holes 16, the first drainage holes 17 and the curved pipes 4 are connected to form a curved flow channel. A second drainage hole 18 is arranged in the bottom plate 5, one end of the second drainage hole 18 is communicated with a lower end of the curved flow channel, and the other end of the second drainage hole 18 is communicated with a downstream face of the bottom plate 5. A second water intake hole 15 is arranged in the top plate 2, one end of the second water intake hole 15 is communicated with an upper end of the curved flow channel, the other end of the second water intake hole 15 is communicated with an upstream face of the top plate 2, and a valve is arranged in the second water intake hole 15.
[0013] When it is necessary to drain water in the front lock chamber into the rear lock chamber, the valve may be opened, and after passing through the second water intake hole 15 and the curved flow channel, the water in the front lock chamber is drained into the rear lock chamber through the second drainage hole 18, so that high-head water filling into the rear lock chamber is changed into low-position water filling, and a water flow speed is slowed down by the curved flow channel, thus greatly reducing an impact of a high-head water flow on the bottom plate 5 of the rear lock chamber.
[0014] When it is necessary to lift the flashboard 3, a lifting rope may be connected to two curved pipes 4 to lift the flashboard 3.
[0015] The valve comprises a cylinder 12 mounted on the top plate 2 and a valve hole 13 arranged in the top plate 2, the valve hole 13 intersects with the second water intake hole 15, a plunger 15 is arranged in the valve hole 13, and the plunger 14 is communicated with the cylinder 12.
[0016] The cylinder 12 drives the plunger 14 to quickly and conveniently open and close the second water intake hole 15 during movement of the valve hole 13.
Description
[0017] A plurality of limiting pipes 7 are mounted on an upstream face of the flashboard 3, a rubber inflatable bag 8 is arranged in each limiting pipe 7, and the rubber inflatable bag 8 is connected with a buoy 6 through a quick coupling and a hose 11. After the hose 11 is communicated with an air source, compressed air enters the rubber inflatable bag 8, and the inflated rubber inflatable bag 8 generates a buoyancy to hold up the flashboard 3 and the top plate 2, so that a gap is formed between the flashboard 3 and the bottom plate 5 or between the flashboards 3. The water in the front lock chamber 20 passes through the gap to quickly enter the rear lock chamber 19, thus realizing quick water filling into the rear lock chamber. Meanwhile, a vertical impact of a water flow on a bottom portion of the rear lock chamber is changed into horizontally entering the rear lock chamber 19, thus weakening the impact of the water flow on the bottom plate 5 of the rear lock chamber.
[0018] A stop valve 9 and a pressure gauge 10 are mounted on the hose 11. As shown in Fig. 2, during inflation of each rubber inflatable bag 8, an inflation amount of the rubber inflatable bag 8 may be determined by observing the pressure gauge 10, so as to adjust a buoyancy of the rubber inflatable bag, and then adjust the gap between the flashboard 3 and the bottom plate 5.
[0019] In a drainage method for a lock chamber by the water retaining and flushing stoplog gate for lock chamber water-drained overhauling, after the valve is opened, water in a front lock chamber passes through the second water intake hole 15, the curved flow channel and the second drainage hole 18, and then is drained into a rear lock chamber. When a water level in the rear lock chamber rises to more than 1/2 height of the bottom plate 5, the rubber inflatable bags 8 are inflated, the rubber inflatable bags 8 drag the flashboards 3 at all levels to move upwardly, and the water in the front lock chamber flows into the rear lock chamber 19 through a gap between the flashboards 3 or a gap between the flashboard 3 and the bottom plate 5, thus avoiding a direct impact of an intake water flow on a bottom portion of the rear lock chamber.
