Abstract
The utility model relates to an arc-shaped combination gate used for the water conservancy and hydropower project. The arc-shaped combination gate is composed of an arc-shaped gate whose upper portion is provided with an opening and a tongue flat gate hinged in the opening of the arc-shaped gate. The bottom edge and the side edge of the tongue flat gate are matched with the water stopping of the arc-shaped gate. The back surface of the tongue flat gate is hinged with a hydraulic opening and closing mechanism arranged on the arc-shaped gate. The contamination in front of a dam can be discharged by controlling the opening and the closing of the tongue flap gate under the condition that the arc-shaped gate is closed.
Description
The utility model relates to the gate on a kind of hydroelectric project.
For a long time, in the power station of having gone into operation, the processing of reservoir area dirt is a great problem of the normal operation of puzzlement power plant always, and especially southern power station is whenever flood season, bank slope is subjected to the erosion of violent storm and the beating of wave around the reservoir area, a large amount of foreign material and spoil enter the reservoir area, swim in the water surface, flow to the dam before, cause unit output to descend, and directly have influence on the safe operation in power station; As the power station, Ge Zhou Ba, the outer maximal head difference of trashrack in flood season can reach 9 meters, and is less as Gong Zui, husky small stream saliva power station, also reaches 3 meters; And because the rotting of spoil, cause before the dam stuffyly, stench is attacked the people.Though but thing interval of grid strip venting fraction is blocked in suitable increase the hydraulic turbine is not caused the flexible foreign material of destruction, still need adopt additive method to be got rid of floating wood, spoil etc.Handling as dirt being put on bank, need are built a fairly large dirt processing and buried the place underground, and do like this except increasing construction investment and operating cost passively, is not radical solving method.At present, blowdown is mainly still adopted the flood spillway Service gate is promoted to certain aperture, the method that dirt is drained into the downstream under the local opening of gate is solved, this measure water loss is bigger, can not often open, the upstream water yield only can satisfy for the generating water situation under, this method for discharging pollution is a cost to lose a large amount of electric energy beyond doubt, and when letting out dirt, dirt bump gate gently then damages the gate flap anticorrosive coat, shorten the anticorrosion cycle of gate, heavy then make panel deformation, water seal damages, and influences the safety of engineering.
The purpose of this utility model provides a kind of combination Segment gate that can remove dirt before the dam effectively.
The utility model comprises Segment gate 4, opening is arranged at the top of Segment gate 4, be hinged with gate door 2 in the described opening, the bottom of gate door 2 and Segment gate 4 are hinged, gate door 2 back sides and hydraulic hoist structure 5 are hinged, the other end of hydraulic hoist structure 5 is hinged on the Segment gate 4, water seal part 3 is equipped with on the side of gate door 2 and base, gate door 2 cooperates with Segment gate 4 sealings, deflector is equipped with at the position that cooperates with the side of gate door 2 on the Segment gate 4, and the locking device 1,6 of gate door 2 is contained on the described guide plate.
The utility model has the advantages that when arc-shaped door is in the complete shut-down position, can be by the open and close of gate door, the discharge of dirt before the control dam, and water loss is minimum, can reduce the influence of dirt to greatest extent to engineering operation, improve the engineering overall efficiency, eliminated the unsafe factor that is brought with conventional gate blowdown; Also can finely tune reservoir water level simultaneously by the switch of gate door.
Further specify the utility model below in conjunction with accompanying drawing:
Fig. 1 is a lateral view of the present utility model;
Lateral plan when Fig. 2 is a gate full-gear of the present utility model;
Fig. 3 is an elevation of the present utility model;
Fig. 4 is a vertical view of the present utility model.
With reference to accompanying drawing:
The utility model comprises a Segment gate 4, opening is arranged at the top of Segment gate 4, be hinged with gate door 2 in the described opening, the bottom of gate door 2 and Segment gate 4 are hinged, gate door 2 back sides and hydraulic hoist structure 5 are hinged, the other end of hydraulic hoist structure 5 is hinged on the Segment gate 4, water seal part 3 is equipped with on the side of gate door 2 and base, gate door 2 cooperates with Segment gate 4 sealings, side matching part with gate door 2 on the Segment gate 4 is equipped with deflector 7, and the locking device 1,6 of gate door 2 is contained on the described deflector.
Generally, the piston rod of hydraulic hoist structure 5 is in extended configuration, and gate door 2 is erect, and constitutes complete gate together with other parts of Segment gate 4, and this moment, the gate door 2 was in the complete shut-down position, and by locking device 1 location.When the need blowdown, gate door 2 is opened, and current and dirt flow through from 2 at gate door in the zone that deflector 7 limits.
