Description
Technical field
The present invention relates to Hydropower Station Underground formula workshops to go out port strobe technical field, more particularly, to a kind of Hydropower Station Underground formula
The arrangement of workshop machine set outlet gate.
Background technology
Powerhouse of hydropower station is divided into ground type workshop and underground powerhouse.The major advantage of underground powerhouse is that workshop does not take up an area
Face position, less with the interference of ground water conservancy project architecture construction, the duration is relatively short, usually by the group of cavern of crossings on different level
At.It requires geological conditions that can meet cavern's stable calculation using the workshop of this form, reduces cavern excavation amount to the greatest extent, avoid
It excavates excessive influence cavern's stable structure and then generates security risk.Conventional hydropower station underground powerhouse goes out port strobe using vertical
Gate slot mode, usually gate lock is above lock top, when unit needs maintenance by closing gate.It is generally disposed at the top of lock chamber
Headstock gear and electric control equipment, this traditional arrangement mode require lock roof panel to export position higher than downstream highest, avoid tail water
Lock top is flooded, therefore outlet lock chamber excavated volume is larger, increases difficulty of construction, and be unfavorable for the stability of cavern's structure, is
This needs to use a large amount of cavern's reinforcement measure, thereby increases construction investment.
Invention content
The present invention provides a kind of arrangement of Hydropower Station Underground formula workshop machine set outlet gate, it is therefore intended that solves existing
Underground powerhouse exports lock chamber and excavates the problem that difficulty is big, construction investment is big.
To achieve the above object, the present invention can take following technical proposals：
The arrangement of Hydropower Station Underground formula workshop machine set outlet gate of the present invention, including be arranged in unit lower exit
Gate in pipeline is prefabricated with the storage gate slot for horizontal gate, the storage door in the outlet conduit top concrete structure
It is provided with hydraulic switch machine platform above slot, is provided with vertical guide between the hydraulic switch machine platform and storage gate slot
Vertical passageway is provided with caulking gum between the hydraulic headstock gear rack and the vertical passageway on hydraulic switch machine platform
Pad, the suspending head end of the hydraulic headstock gear is provided with slides the directive wheel being connected with the vertical track；The gate is close
One end of unit is hinged with storage gate slot, and gate upper surface is hinged by the suspending head of connecting rod and hydraulic headstock gear, gate following table
Face side is coated with the water seal rubber with preburied frame sealing cooperation in outlet conduit.
The hydraulic headstock gear rack is sealing structure.
The hydraulic switch machine platform is located under the peak level of unit downstream.
The arrangement of Hydropower Station Underground formula workshop machine set outlet gate provided by the invention, by the way that sealing hydraulic is arranged
The modes such as headstock gear rack, turning hinge formula open-close sluice gate and embedded gate arrangement, enable headstock gear operating platform to be arranged in down
It swims under peak level, space is used in the operation to reduce gate, greatly reduces cavern excavation amount and gate slot concrete
The amount of pouring not only improves cavern's stable structure, and has saved construction cost.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention（Gate opening state）.
Fig. 2 is the structural schematic diagram of the present invention（Closing gate state）.
Specific implementation mode
As shown in Figure 1, the arrangement of Hydropower Station Underground formula workshop machine set outlet gate of the present invention, including use
The upper horizontal turning hinge open-close type gate 2 being arranged in unit lower exit pipeline 1.Specifically, 1 top concrete knot of outlet conduit
Storage gate slot 3 is prefabricated in structure, 3 inside of storage gate slot is close to one end of unit（It is left end in figure）Embedded turning hinge free bearing, to hinged
Gate 2, gate 2 can be rotated around hinged shaft, can be completely embedded into when in horizontality in the storage gate slot 3 and are used as outlet conduit 1
A part for roof does not influence passing through for normal flow；Hydraulic switch machine platform 4 has been built in 3 top of storage gate slot, the hydraulic switch
It is connected by the vertical passageway 6 with vertical guide 5 between machine platform 4 and storage gate slot 3；It is installed on hydraulic switch machine platform 4
There is hydraulic headstock gear 7, the rack of the hydraulic headstock gear 7 is provided with caulking gum between sealed structure, with vertical passageway 6
Pad 8, and be bolted together, to ensure that higher than when opening and closing machine platform water leak accident does not occur for the level of tail water；In order to
The hydraulic stem for ensuring hydraulic headstock gear 7 axially movable, avoids hydraulic pressure rod bending or destroys sealing, in hanging for hydraulic headstock gear 7
Head end is equipped with slides the directive wheel 9 being connected with vertical track 5, it is made vertically to be run along track；Meanwhile hydraulic headstock gear
7 suspending head is hinged by connecting rod 10 and 2 upper surface of gate, and 2 rotating folding of gate is driven by hydraulic headstock gear 7；In addition, gate
2 lower surfaces（That is gate panel）Side is also wrapped on water seal rubber 12, for making gate 2 be in closed state as shown in Figure 2
When, excellent sealing can be formed with 11 palette of preburied frame being arranged in outlet conduit 1, to stop that downstream water enters
Unit provides nonirrigated farmland for unit and overhauls condition.
Above-mentioned hydraulic switch machine platform can be arranged under the peak level of downstream, reduce the operation of gate with empty
Between, cavern excavation amount and gate slot concreting amount are greatly reduced, not only improves cavern's stable structure, and saved and be constructed into
This, can promote the use of hydraulic and hydroelectric engineering underground power house machine set outlet gate and be arranged in the indoor technical field in hole.
