Abstract
The invention discloses a bottom hole top plate gate groove plug device used under the dam notch and bottom hole united discharge condition. The bottom hole top plate gate groove plug device comprises a gate groove lifting mechanism, a gate top plate bearing mechanism and a sealing water stop mechanism. The gate groove lifting mechanism is used for transmitting opening and closing of a gate and fixing the gate. The gate top plate bearing mechanism is used for connecting the gate groove lifting mechanism and the sealing water stop mechanism, bearing the gravity of the gate, transmitting the load and connecting a gate opening and closing device. The sealing water stop mechanism is used for sealing a gap of a gate groove. The bottom hole gate is fixed through engagement force between racks and gears, and gate groove damage due to sharp vibration of the gate in the discharge process is avoided; and the bottom hole gate groove is sealed, vortex in front of the gate is avoided, and the hydraulic conditions of the gate are improved.
Description
Technical field
The invention belongs to Hydraulic and Hydro-Power Engineering and mechanical engineering technical field, be specifically related to a kind of concrete dam body breach bottom outlet joint discharge condition lower bottom hole top board gate slot slot plug device.
Background technology
The Hydraulic and Hydro-Power Engineering of building, when its construction diversion flow is very large, often adopts concrete dam body future insufficiency and bottom outlet joint discharge.General bottom diversion outlet gate slot is connected without retraining with gatehouse, gate high vibration under flow action during earial drainage, and collision gate slot inwall, usually causes gate slot structure to be destroyed; Simultaneously because current enter from untight bottom outlet gate slot, before making lock there is eddy current in the water surface, occurs cavitation corrosion at bottom outlet inducer, weakens the supporting capacity of gate support, produces engineering safety hidden danger.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of concrete dam body breach bottom outlet joint discharge condition lower bottom hole top board gate slot slot plug device, ensure the structural safety of bottom diversion outlet and gate slot under concrete dam body breach bottom outlet joint discharge condition, improve gate hydraulics.
The technical solution adopted in the present invention is: a kind of dam body breach bottom outlet joint discharge condition lower bottom hole top board gate slot slot plug device, is characterized in that: comprise gate slot elevating mechanism, gate top board load carrier and hermetic seal mechanism;
Described gate slot elevating mechanism comprises tooth bar, gear, gear fixed head, and described gate top board load carrier comprises gate top board, hanger, bolt, and described hermetic seal mechanism comprises gate support, hermetic seal batten;
Gate is fixedly mounted on described gate top board; Described tooth bar is fixedly mounted on hollow quoin, and described gear is fixedly mounted on described gear fixed head, and described gear fixed head is fixedly mounted on described gate top board; Described gate top board is provided with described hanger for connecting opening and closing device, when described gate opening/closing, the keying of described tooth bar, gear drive gate, and produce snap-in force and fix described gate;
Described gate opens and closes in described gate support, described hermetic seal plate is embedded with in described gate support, after gate is closed, be bolted to described in described hermetic seal plate passes through on described gate top board, block described gate upstream face gate slot gap, avoid current to enter gate slot and form double-deck overcurrent, improve gate hydraulics.
As preferably, gate is welded on described gate top board, and described gear fixed head is welded on described gate top board.
The invention has the beneficial effects as follows:
1, while being convenient to gate opening/closing, realize bottom gate and be engaged with gate slot and retrain, prevent because gate high vibration destroys gate slot;
2, the present invention utilizes the gap that slot plug device shutoff gate and gate slot are formed, and to avoid before gate, because the double-deck overcurrent of concrete dam body breach and bottom outlet forms eddy current, improving gate hydraulics;
3, the present invention can be used as a part for following shutoff gate, reduces shutoff difficulty, saves material, reduces construction costs.
