Abstract
The utility model relates to a well type water inlet/outlet structure for a water-pumping energy-storing power station. The technical problem which needs to be solved is to provide the well type water inlet/outlet structure for a water-pumping energy-storing power station; a well type water inlet/outlet is positioned in a reservoir, the position selection can not be limited by geological conditions of the topographic form of a bank slope, and the utility model can be swimmingly and limberly connected with a tunnel; the excavated volume of the bank edge is less, the loss of the water head of the water inlet/outlet is small, and the anti-vortex effect is good; the utility model is provided with a horizontal gate which is convenient to open. In order to achieve the purpose, the utility model has the technical scheme that the structure of the utility model presents a vertical well type, and a top cover is arranged on the top of the utility model; a water inlet/outlet is provided with a plurality of holes which are radially arranged; gate piers are arranged on both ends of each hole, the tail of each gate pier shrinks to form a sharp angle, and anti-vortex beams which are arranged in a staircase shape are arranged between two adjacent gate piers; bulkhead gates, the amount of which is consistent with the amount of the holes are arranged around the water inlet/outlet; a door shaft is arranged on the position of the gate pier of one side of each gate, and a door storing groove is arranged in the gate pier of the side provided with the door shaft. The utility model can be used for structural arrangement of the water inlet/outlet of the water-pumping energy-storing power station.
Description
Technical field
The utility model relates to a kind of well formula intake-outlet structure of pumped storage power plant.Be applicable to pumped storage power plant intake-outlet structural configuration.
Background technology
In the advancing of the pumped storage power plant of at home and abroad having built/delivery port pattern, side formula and well type structured pattern have both at the same time, and need according to all multifactor relatively backs such as landform, geological conditions, flow-shape, connection and reasonable arrangement selected.The side formula advances/and delivery port is built in the reservoir bank, and easy to connect with the storehouse bank, the layout of traffic, gate is all convenient, imports and exports the section flow direction and changes for a short time, and velocity flow profile is more easily adjusted evenly when going out to flow, and head loss is generally less.But it is higher relatively that hillside fields, side formula water inlet opposite bank shape geological conditions requires, and the bank excavated volume is bigger.The derivation conduit of domestic a lot of pumped storage power plants is that horizontal direction enters reservoir, landform, geological conditions are better again, therefore the side formula advance/delivery port is used morely, for example: the Ming Tombs of having built, extensively hold (one, second phase), day waste level ground and in pumped storage power plants such as the Tongbai of building, Tai'an, Yixing, Bao Quan.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of well formula intake-outlet structure of pumped storage power plant is provided, and the well formula advances/and delivery port is arranged in reservoir, and the restriction of bank slope topographic and geologic condition is selected not to be subjected in the position, is connected more smooth and easy, flexible with tunnel; The bank excavated volume seldom; Advance/the delivery port head loss is little; Anti-whirlpool is effective; The I-shaped gate is set, makes things convenient for gate opening/closing.
The technical scheme that the utility model adopted is: the well formula intake-outlet structure of pumped storage power plant, it is characterized in that this structure is vertical shaft type, the top is provided with top cover, the intake-outlet branch has several holes, be radial arrangement, each hole two ends is provided with gate pier, its afterbody is shrunk to wedge angle, be provided with the anti-whirlpool beam of stepped arrangement between adjacent two gate piers, the intake-outlet border arranges and the corresponding to Emergency Gate of described hole quantity that every fan brake Men Zaiyi side gate pier place is provided with door-hinge and has the storage gate slot in the gate pier of this side.
The upper end of every described door-hinge is connected with crank, and the other end of crank is connected with the opening/closing device of top cover central authorities.
Described Emergency Gate is enclosed box-structure.
Described intake-outlet is arranged six holes at least.
Described anti-whirlpool beam is provided with three layers, and Emergency Gate and storage gate slot are positioned at the below of a bottom anti-whirlpool beam.
The beneficial effects of the utility model are: this structural configuration is flexible, and reduced investment is mild for the reservoir landform especially, geological conditions is relatively poor, and the side formula advances/and delivery port can not satisfy the power station of water conservancy project arrangement requirement, and the advantage of this structure is fairly obvious.By rational layout, reduced head loss, avoided harmful air-breathing whirlpool, operating gate is very convenient.Thisly advance/the delivery port structural shape has been built does not at home also have application example in the engineering.
Description of drawings
Fig. 1 is a vertical view of the present utility model.
Fig. 2 is a main sectional view of the present utility model.
The specific embodiment
As shown in Figure 1, 2, present embodiment is a vertical shaft type intake-outlet structure, and the top is concrete top cover 1, and top cover is risen a little more than level of dead water, does not establish trashrack.The intake-outlet branch has six above holes 9, this example is eight holes, is radial arrangement, and each hole two ends is provided with gate pier 8, the afterbody of each gate pier is shrunk to wedge angle, be provided with from bottom to top three layers of anti-whirlpool beam 2 of stepped arrangement between adjacent two gate piers, anti-whirlpool beam adopts stepped arrangement, and its build adapts to the water movement direction more, the assurance current are smooth-going, reduce the base plate recirculating zone, effectively reduce head loss, do not produce harmful air-breathing whirlpool in the influent stream operating mode.The intake-outlet border is arranged and the corresponding to Emergency Gate 4 of described hole 9 quantity, guarantee when a hole overhauls, not influence the operation of adjacent unit, be that this example is furnished with eight fans, one word gate-type Emergency Gate, every fan brake Men Zaiyi side gate pier place is provided with door-hinge 5 and has storage gate slot 3 in the gate pier of this side, the upper end of every door-hinge 5 is connected with crank 6, the other end of crank is connected with the opening/closing device 7 of top cover 1 central authorities, and this routine opening/closing device is a bottle gouard moved by hands.Emergency Gate 4 and storage gate slot 3 are positioned at the below of a bottom anti-whirlpool beam 2.
This routine Emergency Gate 4 adopts enclosed box-structure, but utilizes buoyancy of water balance portion gate weight, gate can be rotated around door-hinge with manpower realize opening and closing operation, and the pressure reduction when utilizing emptying reaches the gate sealing purpose.When reservoir level was reduced to level of dead water, operating personnel can rotate door-hinge by crank gate is opened and closed operation by marking time and People's Bank of China's suspension bridge arrival operating gate platform on the bank slope, and gate opening is locked in the groove (storage gate slot 3) of gate pier at ordinary times.
