Abstract
The utility model belongs to the field of designing workshops of hydropower stations, and in particular relates to a gate slot of a workshop of a hydropower station. A gate is arranged on the gate slot. The gate slot is characterized in that telescopic columns are arranged in the gate slot and are arranged at the bottom of the gate slot, the tops of the telescopic columns are fixed at the bottom of the gate; a column library is arranged at the bottom of the gate slot and is used for storing the telescopic columns; the telescopic columns are compressible plastic telescopic columns or rigid structure telescopic columns; and the column library is a concrete pothole or a concrete pothole lined with steel plates. The utility model provides the gate slot of the workshop of the hydropower station, solving a problem that the gate slot can be automatically temporarily blocked when the gate is started (lifted up) in a background technology.
Description
Technical field
The utility model belongs to the powerhouse of hydropower station design field, is specifically related to a kind of powerhouse of hydropower station gate slot.
Background technology
China's waterpower resourses (water ability) are very abundant; The first according to the world; Single economic developable total installation of generating capacity (power) just reaches about 4.5 hundred million kilowatts; Exactly because but the abundant reason of waterpower resourses (water can) perhaps, everybody does not note how improving the problem of generating efficiency, especially how improves the problem of generating efficiency through the design of optimizing the power generation construction thing.
Generated output (installed capacity) depends on the product of the discharge of river and effective head, and effective head is the productive head after the head loss of gross head deduction, and head loss mainly is the head loss that occurs in gate slot.Therefore, how can interim automatically shutoff gate slot when (mentioning) at gate opening, be problem just to be solved.
The utility model content
The purpose of the utility model is to provide a kind of powerhouse of hydropower station gate slot, with solve the gate opening described in the background technology can be automatically when (mentioning) problem of shutoff gate slot temporarily.
For reaching above-mentioned purpose, the utility model provides a kind of powerhouse of hydropower station gate slot, and it is provided with gate, it is characterized in that: be provided with telescopic mast in this gate slot, this telescopic mast is positioned at the bottom of this gate slot, and its top is fixed on the bottom of said gate; The bottom of this gate slot is provided with the post storehouse that is used to store this telescopic mast.
Said telescopic mast is compressible plastics telescopic mast or rigidity framework telescopic mast.
Said post storehouse is the coagulation heatable adobe sleeping platform groove after coagulation heatable adobe sleeping platform groove or the steel plate liner.
The utility model has the advantages that: utilize the concrete in mass completion coagulation heatable adobe sleeping platform groove of gate slot bottom or the coagulation heatable adobe sleeping platform groove conduct after the steel plate liner to deposit telescopic mast post storehouse, can save the concrete work amount; Telescopic mast is compressible plastics, rubber telescopic mast or rigidity framework telescopic mast, and manufacture craft is simple, cheap, be easy to apply; The compression of telescopic mast or promote and not need special equipment, power or technology, that leans on gate fully heavyly puts and promotes the purpose that reaches interim shutoff gate slot, simple to operate.The more important thing is the gate slot that provides through the utility model, improved the effective head amount in power station, practiced thrift the energy and cost.

The specific embodiment
Structure of hydropower station is in order to control flow and head, is provided with the gate of control flow and head, title service gate in the import of generating set; Import at generating set is provided with the gate that overhauls generating set respectively with outlet, claims access door; The head loss that three fan brake gate slotes produce is about 0.4m, accounts for 5/1000 of effective head usually, just reaches about 4.5 hundred million kilowatts of estimations by total installation of generating capacity (power), and about 10,000,000,000 kilowatt hours of electric weight (degree) are sent in then annual loss.
For fear of this loss; Like Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, the utility model provides a kind of powerhouse of hydropower station gate slot, and it is provided with gate 8; Be provided with telescopic mast 5,6,7 in this gate slot; As shown in Figure 2, access door 2, service gate 3 and tail water overhauling door (gate slot) bottom telescopic mast 5,6,7, its top is fixed on the bottom (see figure 3) of gate 8; The bottom of this gate slot is provided with post storehouse 9 (see figure 5)s that are used to store this telescopic mast 5,6,7.
Utilize the concrete in mass completion coagulation heatable adobe sleeping platform groove of gate slot bottom or the coagulation heatable adobe sleeping platform groove conduct after the steel plate liner to deposit telescopic mast post storehouse, can save the concrete work amount; The compression of telescopic mast 5,6,7 or promote and not need special equipment, power or technology, that leans on gate 8 fully heavyly puts and promotes the purpose that reaches interim shutoff gate slot, simple to operate.
Above gate slot will be reduced the about 0.13m of head loss by the interim shutoff of telescopic mast.Improve the effective head amount in power station, practiced thrift the energy and cost.
