Abstract
The utility model discloses a laminated water taking structure sets up the waterwall between the bulkhead gate of trash rack and water inlet, on the waterwall not the co -altitude interval set up the water intaking hole more than two, one set of gate that can overturn has been established in every water intaking hole, the gate that can overturn rotates along the gate center pin that can overturn. Compared with the prior art, the utility model discloses operate more in a flexible way, can satisfy the reservoir water level and frequently change, have positive result of use.
Description
Technical field
The utility model relates to a kind of Hydraulic and Hydro-Power Engineering layered water drawing structure, especially relate to a kind of in Hydraulic and Hydro-Power Engineering intake place can obtain superficial water for slowing down the layered water drawing structure of Water Temperature.
Background technology
Big-and-middle-sized reservoir is after especially the good reservoir of adjusting function forms, and layering will appear in reservoir area water temperature, in reservoir area lower floor's water temperature under let out the distribution of water temperature to lower reache impacted, thereby to irrigating, aquatile causes adverse effect. In order to address this problem, numerous reservoirs all change deep water intake into stratified pumping, all can obtain exactly upper water under different operating modes.
At present, layered water intake structures pattern is mainly by patterns such as multilayer intake, Stoplog gates. The feature of multilayer intake arrangement is along being vertically set as highly respectively several imports by water intaking by water inlet, each import can meet water intaking ability, when water level is higher, close lower water inlet gate, when water level is lower, open lower water inlet gate, multilayer intake is mainly applicable to the engineering that the reservoir depth of water is little, drainage flow is less.
Stoplog gate layered water drawing structure be more piece is set in intake tower can be along the Stoplog gate of the short transverse lifting of tower body, every joint Stoplog gate all can contact by hydraulic automatic grabbing beam and lift structure. Block lower floor's water at low temperature in reservoir with Stoplog gate, the operation of Liangmen through the stack, the water-carriage system that makes reservoir surface water enter generating or irrigate by aperture, Stoplog gate top, according to the variation of reservoir operating level, mention or put down the Stoplog gate of corresponding joint number, quote reservoir surface water thereby reach, improve the lower warm object that sluices. For the ease of the elevating control of Stoplog gate, on the body of intake tower, be respectively equipped with the stoplog groove of arranging along the short transverse of tower body, Stoplog gate is arranged in stoplog groove. The deficiency of Stoplog gate water intaking structure is complex structure, leaning on headstock gear and Automatic coupling and decoupling beam to take out section by section Stoplog gate easily breaks off relations, and complete Stoplog gate and arrange that the required time often needs several hours or 10 several hours, inapplicable for the reservoir that reservoir level change frequency is larger.
Utility model content
The purpose of this utility model is to provide a kind of layered water drawing structure, and stratified pumping is as required let out the impact on downstream ecology environment to slow down under water at low temperature, to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of layered water drawing structure, between trash rack and the bulkhead gate of water inlet, waterwall is set, on waterwall, differing heights interval arranges plural water intaking hole, each water intaking hole is provided with a set of turning gate, and turning gate rotates along turning gate central shaft.
The quantity in described water intaking hole is determined according to water temperature of reservoir structure.
Described turning steel gate height be generally 2 ~ 5 meters, concrete size is determined according to water temperature of reservoir structure.
Described turning steel gate rotational power plant is that motor drives.
Described turning steel gate and waterwall are salable.
Compared with prior art, the utility model operation is more flexible, can meet reservoir level and frequently change, and has positive result of use.
Brief description of the drawings
Fig. 1 is layered water drawing structure vertical cross section;
Fig. 2 is turning steel gate schematic diagram;
Fig. 3 is layered water drawing structure section plan.
The turning gate of description of reference numerals: 1-, the turning gate central shaft of 2-, 3-water inlet, 4-bulkhead gate, 5-trash rack, 6-water inlet base plate, 7-dividing plate.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment:
As shown in Figure 1, first, this layered water drawing structure,: between trash rack 5 and the bulkhead gate 4 of water inlet 3, waterwall is set, on waterwall, differing heights interval arranges plural water intaking hole, each water intaking hole is provided with a set of turning gate 1, and turning gate 1 rotates along turning gate central shaft 2.
Gate is opened successively from top to bottom, and the gate quantity of opening is definite according to reservoir level and water temperature of reservoir situation, and before dam, current flow into water inlet base plate 6 from the gate of opening, and enter water inlet 3. Reservoir surface water is taken in guarantee, improves sluicing temperature under reservoir.
Certainly, be more than concrete exemplary applications of the present utility model, the utility model also has other embodiment, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the desired protection domain of the utility model.
