Detailed Description
A gate chamber drain overhaul water retaining flushing stop log gate comprises a gate slot 1, a bottom plate 5, a plurality of gate plates 3 and a top plate 2, wherein the bottom plate 5, the plurality of gate plates 3 and the top plate 2 are inserted into the gate slot 1; a second drain hole 18 is formed in the bottom plate 5, one end of the second drain hole 18 is communicated with the lower end of the bent runner, and the other end of the second drain hole 18 is communicated with the back water surface of the bottom plate 5; a second water inlet hole 15 is formed in the top plate 2, one end of the second water inlet hole 15 is communicated with the upper end of the bent flow channel, the other end of the second water inlet hole 15 is communicated with the upstream face of the top plate 2, and a valve is arranged in the second water inlet hole 15.
When the water in the front stage lock chamber needs to be discharged into the rear stage lock chamber, the valve can be opened, the water in the front stage lock chamber passes through the second water inlet hole 15 and the bent flow passage and then is discharged into the rear stage lock chamber through the second water outlet hole 18, therefore, the high-water-head water filling of the rear stage lock chamber is changed into the low-water-head water filling, the water flow speed is slowed down by the bent flow passage, and the impact of the high-water-head water flow on the bottom plate 5 of the rear stage lock chamber is greatly weakened.
When the flashboard 3 needs to be lifted, a lifting rope can be connected to the two curved pipes 4 to lift the flashboard 3.
The valve comprises a cylinder 12 installed on the top plate 2 and a valve hole 13 formed in the top plate 2, the valve hole 13 is intersected with a second water inlet hole 15, a plunger 14 is arranged in the valve hole 13, and the plunger 14 is communicated with the cylinder 12.
The cylinder 12 drives the plunger 14 to open and close the second water inlet hole 15 quickly and conveniently in the process of moving the valve hole 13.
A plurality of limiting pipes 7 are arranged on the upstream surface of the gate plate 3, rubber air bags 8 are arranged in the limiting pipes 7, and the rubber air bags 8 are connected with the buoy 6 through quick connectors and hoses 11. After the hose 11 is communicated with an air source, compressed air enters the rubber air bag 8, the inflated rubber air bag 8 generates buoyancy to lift the gate plate 3 and the top plate 2, a gap is formed between the gate plate 3 and the bottom plate 5 or between the gate plate 3 and the gate plate 3, water in the front stage chamber 20 passes through the gap to rapidly enter the rear stage chamber 19, rapid water filling of the rear stage chamber is achieved, meanwhile, water flow vertically impacts the bottom of the rear stage chamber and horizontally enters the rear stage chamber 19, and impact of the water flow on the bottom plate 5 of the rear stage chamber is weakened.
A shut-off valve 9 and a pressure gauge 10 are mounted on the hose 11.
