Abstract
The utility model discloses a power station tail lock placer. Including gate pier (1), gate pier (1) top surface is draft tube deck (2), and draft tube deck (2) surface is located below the design flood position, just is higher than all units and completely sends out the tailwater level with gate (3) height, being equipped with on draft tube deck (2) and opening and close framed bent (4) and floodgate door hole (5), floodgate door hole (5) are the rectangular hole, and the length direction of floodgate door hole (5) is perpendicular with water flow direction, the degree of depth of floodgate door hole (5) is greater than gate (3) height, and the drill way of floodgate door hole (5) is equipped with locking roof beam (6) of a pair of symmetry, and locking roof beam (6) is perpendicular with floodgate door hole's (5) length direction, locking roof beam (6) bottom is equipped with the hoist of being connected with gate (3). The utility model discloses a place the gate in floodgate door hole, avoided flood period the flood or the stone sediment produce great influence to the gate, reduced the risk that the gate became invalid, provide the guarantee for the safe operation in power station.
Description
Technical field
This utility model is related to a kind of hydropower station tail water gate apparatus for placing, belongs to Hydraulic and Hydro-Power Engineering technical field.
Background technology
For the higher power station of tail water design flood level, check flood level, if the setting of draft tube deck elevation is higher than tail
Water check flood level, will increase larger civilwork engineering quantity and investment, in order to reduce civilwork engineering quantity and investment, typically by tail
Horizontal stand elevation is set lower than tail water design flood level, that is, be equivalent to tail water design flood level, the relatively low power station of check flood level
Central tail lock inspection platform.It is usually that tail lock is placed on draft tube deck, gate bottom is stamped on locking beam,
Top, side are fixed using certain way, and this gate modes of emplacement affects when flood is less less, but when meet with great flood or
During person's over-level flood, taken due to flood and wrap up in rock ballast collision gate and turbulent water, lead to gate damaged, or even cannot normally open
Close or gate is flushed away, have a strong impact on the safe operation in power station.
Content of the invention
The purpose of this utility model is, provides a kind of hydropower station tail water gate apparatus for placing.Avoid breaking due to gate
Damage or the normal safe losing efficacy and affecting power station run.
The technical solution of the utility model：
A kind of hydropower station tail water gate apparatus for placing, including gate pier, is provided with draft tube deck, draft tube deck table in gate pier top surface
Face is located at below design flood level, and completely sends out tailwater level higher than all units and add gate height；Draft tube deck is provided with keying row
Frame and gate hole, gate hole is rectangular opening, and the length direction of gate hole is vertical with water (flow) direction；The depth of gate hole is more than gate
Highly, the aperture of gate hole is provided with a pair symmetrical locking beam, and locking beam is vertical with the length direction of gate hole；Locking beam bottom
It is provided with the suspender being connected with gate.
Compared with prior art, this utility model is by being placed on gate in the hole by gate, it is to avoid flood period flood or
Person's rock ballast produces large effect to gate, reduces the risk of gate inefficacy, is that the safe operation in power station provides guarantee.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the top view of Fig. 1.
In figure is labeled as：1- gate pier, 2- draft tube deck, 3- gate, 4- open and close framed bent, 5- gate hole, 6- locking beam.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, but not as new to this practicality
Any restriction of type.
Embodiment
A kind of hydropower station tail water gate apparatus for placing, as shown in Figure 1：Including gate pier 1, gate pier 1 top surface is draft tube deck 2,
Draft tube deck 2 surface is located at below design flood level, and completely sends out tailwater level higher than all units and add gate 3 highly；Draft tube deck 2
It is provided with keying framed bent 4 and gate hole 5, gate hole 5 is rectangular opening, the length direction of gate hole 5 is vertical with water (flow) direction；Gate
The depth in hole 5 is more than gate 3 height, and the aperture of gate hole 5 is provided with a pair symmetrical locking beam 6, locking beam 6 and gate hole 5
Length direction is vertical；Locking beam 6 bottom is provided with the suspender being connected with gate 3.
The technical scheme of this example includes：
1st, tail water gate pier structure is designed to structure as shown in Figure 1, gate hole 5 is set in gate pier 1；
2nd, after should ensure that gate 3 is placed in gate hole 5, gate 3 Bottom Altitude is higher than tail when all units are completely sent out
Water level elevation, that is, draft tube deck 2 elevation should be greater than all units and completely send out tailwater level+gate height；
3rd, using locking beam 6, gate 3 is hung in gate hole 5, locking beam 6 is fixed on draft tube deck 2；
4th, during gate 3 maintenance, using headstock gear, gate 3 lifting is placed on draft tube deck 2.
Points for attention：（1）Locking is placed on the gate Bottom Altitude of gate in the hole when completely must send out higher than whole units
Tailwater level, it is to avoid the disturbance to gate for the generating tail water；（2）The fixed form of locking beam will guarantee reliability.
