Abstract
The utility model provides a kind of hydraulic and hydroelectric engineering gate chamber exhaust structure, gate shaft, gate, exhaust passage is arranged in the gate chamber, it is characterized in that venthole is arranged by the gate shaft, the top of the venthole has transverse passage-way, in gate shaft, the venthole is connected to transverse passage-way and communicates the venthole and gate shaft and constitute exhaust main channel in the exit of transverse passage-way；Gas vent top exit channel is also set up above the gas vent, the gas vent and top exit channel communicate, and the outlet in top exit channel is the outlet that can be covered and open, and the exit in top exit channel is other at the top of gate chamber inner gate well.A transverse passage-way, connection venthole and gate shaft is arranged on venthole top in the utility model, and transverse passage-way, which can change the direction of a stream of water, reduces security risk, it avoids flooding gate chamber, top exit can usually cover, and can open when needing, it is practical flexible, increase inspection platform working space.
Description
Technical field
The utility model relates to a kind of exhausts of the hydraulic and hydroelectric engineering gate chamber of hydraulic engineering more particularly to gate shaft to tie
Structure.
Background technique
In hydraulic and hydroelectric engineering, underground water tunnel needs to be arranged various gates for water blocking, and such as bulkhead gate, work lock
Door etc., in tunnel, gate opens (promotion) or closing (decline) in gate shaft and will cause one lateral pressure of closing and increase suddenly
Or become smaller, therefore one of venthole connection tunnel and gate chamber can be set beside gate shaft, for tonifying Qi to balance pressure.But
It is that will cause tunnel flow instability in water turbine set removal of load, surges in venthole formation, or even gate chamber can be flushed to,
Threaten gate chamber safety, it is therefore desirable to design biggish structure, gate chamber is avoided to be flooded, and engineering cost is caused to increase.
Utility model content
It is avoided that gate chamber is flooded the water conservancy and hydropower work fallen the technical problem to be solved by the utility model is to provide a kind of
Journey gate chamber exhaust structure, and project cost can be reduced or hardly increase project cost.For this purpose, the utility model is using following
Technical solution:
Gate shaft, gate, exhaust passage, feature is arranged in hydraulic and hydroelectric engineering gate chamber exhaust structure, the gate chamber
Be that venthole is arranged by the gate shaft, the top of the venthole has a transverse passage-way, the exit of transverse passage-way in gate shaft,
The venthole is connected to transverse passage-way and communicates the tunnel and gate shaft and constitute exhaust main channel；In the gas vent
Top also sets up gas vent top exit channel, and the gas vent and top exit channel communicate, the outlet in top exit channel
For the outlet that can be covered and open, the exit in top exit channel side at the top of gate chamber inner gate well.
Further, the upper outlet of the venthole is provided with lid, and in described cover, the lid is used as gate chamber
In inspection platform.
Further, the top exit channel and the gas vent be on the same line.
Due to using the technical solution of the utility model, a transverse passage-way, connection is arranged on venthole top in the utility model
Way vent hole and gate shaft, transverse passage-way can change the direction of a stream of water and eliminate safe hidden trouble, and avoid flooding gate chamber, top exit is usually
It can cover, can be opened when needing, it is practical flexible, increase inspection platform working space.
Detailed description of the invention
Fig. 1 is gate shaft floor plan.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Specific embodiment
Referring to attached drawing.The exhaust structure of hydraulic and hydroelectric engineering gate chamber provided by the utility model, the gate chamber 1 are set
Gate shaft 4, gate 3, exhaust passage are set, venthole 5 is set by the gate shaft 4, the top of the venthole 5 has transverse passage-way
7, the outlet 70 of transverse passage-way 7 is in gate shaft 4, the venthole be connected to transverse passage-way 7 and communicate tunnel 2 and gate shaft 4 and
Constitute exhaust main channel；Gas vent top exit channel 6, the gas vent 5 and top are also set up in the top of the gas vent 5
Exit passageway 6 communicates, and the outlet 60 in top exit channel 6 is the outlet that can be covered and open, the outlet 60 in top exit channel 6
It is in other at the top of gate chamber inner gate well.The height of outlet 70 lower than outlet 60 height, and towards in gate shaft, gate shaft
It can be used as the pond of coming down in torrents that gas vent is surged, make enough height come down in torrents space and can reduce gas vent of surging, outlet 60
Upward and it can cover and open, two 60,70 action compensatings of outlet, significant effect both avoids flooding gate chamber, it is hidden to eliminate safety
Suffer from, and gate chamber elevation can be reduced, reduce structure, reduces engineering cost.
The upper outlet of the venthole is provided with lid 9, usually, can cover the lid 9, as the maintenance in gate chamber
Platform.Increase gate chamber platform area, facilitate work, when needing to overhaul, opens top blind flange, enter from top exit；When
When water level rises to certain altitude, gate shaft can be flowed to from transverse passage-way, avoid water level from rising to gate chamber, cause to flood loss.
Preferably, the top exit channel and the gas vent be on the same line.
The foregoing is merely the structure features of specific embodiment of the utility model, but the utility model to be not limited to
This, in the field of the utility model, made changes or modifications all cover practical new at this any those skilled in the art
Among the protection scope of type.
