The water height that blocks of the full state of described rubber dam bag is 20-150cm.
The long limit, one end that described water-stop is connected to rubber dam bag is connected with the door-plate surface of described door body towards water channel upstream, and the long limit of the other end of rubber dam bag is connected towards the surface in water channel downstream with described door body.
Described rubber dam bag is formed by a plurality of monomer rubbers dam bag serial connection; A plurality of monomer rubbers dam bag is end-to-end and locates water-stop connection; Each monomer rubber dam bag has respectively rubber dam bag and charges and discharge control device.
A plurality of cabins that charge and discharge of the inner axial distribution of described rubber dam bag, respectively charge and discharge cabin and have respectively rubber dam bag and charge and discharge control device.
Method of work of the present invention, according to the following steps operation:
1), at steel gate, during in erectility, utilize rubber dam bag to charge and discharge control device and be filled to full state in rubber dam bag;
2), the upstream inpoundment of steel gate is to rubber dam bag apical margin height;
3), while discharging water, utilize rubber dam bag to charge and discharge the progressively off-load of control device operation rubber dam bag, progressively reduce rubber dam bag height, make current let out downstream by design discharge; Until the complete off-load of rubber dam bag.
After step 3), then topple over by door body drive driving gate body, further discharge water.
Described rubber dam bag is formed by a plurality of monomer rubbers dam bag serial connection; Each monomer rubber dam bag has respectively rubber dam bag and charges and discharge control device; When carrying out step 3), first start aforementioned each monomer rubber dam bag and there is respectively rubber dam bag and one of charge and discharge in control device, by its corresponding monomer rubber dam bag off-load, restart other monomer rubber dam bag.
A plurality of cabins that charge and discharge of the inner axial distribution of described rubber dam bag, respectively charge and discharge cabin and have respectively rubber dam bag and charge and discharge control device; When carrying out step 3), first start the aforementioned cabin that respectively charges and discharge and there is respectively rubber dam bag and one of charge and discharge in control device, by its corresponding cabin off-load, restart other monomer rubber dam bag.
The present invention arranges the rubber dam bag of " small-sized " at the steel gate top of prior art, utilize it to charge and discharge characteristic, can effectively reduce water level 20-150cm, and then reduces the water body static pressure of suffered high water level one side of door body.While discharging water on a small quantity, only need utilize rubber dam bag can realize the operation that discharges water; In the time of need discharging water in a large number, after the complete off-load of rubber dam bag, restart a body and discharge water, can greatly reduce the energy consumption of a body drive.In addition, because rubber dam bag belongs to compliant member, in the process of discharging water, contact all the time the lower edge of current, can effectively absorb water flow vibration, avoid water flow vibration to be directly delivered on rigid door body, the door body of damage rigidity and connection thereof, driving mechanism.The present invention can reduce the Energy in use of steel gate greatly, extends the application life of steel gate.
