Description
Technical field
The utility model relates to hydraulic engineering technical field, particularly the absorption basin in power station.
Background technology
In the Energy Dissipation Modes in power station, absorption basin is comparatively common one, and it is arranged on the downstream part of outlet structure escape works.By forming hydraulic jump in absorption basin, the torrent gushed by outlet structure escape works is transformed into unhurried current, to eliminate unnecessary kinetic energy.Absorption basin often has fluid stable, feature that effect of energy dissipation is good.But in existing absorption basin, it needs to build longer protection-apron, according to multistage energy-dissipating structure, its overall length is longer, causes the arrangement space of building not enough, earthwork evacuation amount and concrete square amount larger, construction costs is higher, is more not suitable for for narrow region.
Utility model content
The applicant, for the above-mentioned shortcoming of prior art, carries out studying and improving, and provides a kind of novel hydropower absorption basin structure, and it substantially reduces protection-apron length, is adapted to the use of various region, has low, the convenient feature of arranging of cost.
In order to solve the problem, the utility model adopts following scheme:
A kind of novel hydropower absorption basin structure, comprise the absorption basin being arranged at outlet structure escape works downstream, the water intake end of absorption basin is with energy dissipating tooth bank, and its discharge ends is with energy dissipating tail bank, energy dissipating tooth bank is with cancave cambered surface and the backwater cancave cambered surface of meeting water, and the leading portion of meet water cancave cambered surface and absorption basin seamlessly transits; The top of energy dissipating tooth bank arranges watertight shutter, watertight shutter is tilted to lower setting along the drainage direction of absorption basin, the lower end of watertight shutter is with water guide web plate and weather board, weather board is placed in the top of water guide web plate, with water guide space between weather board and water guide web plate, watertight shutter and water guide web plate are connected respectively by support bar and absorption basin.
Further improvement as technique scheme:
Described water guide inclined meshed plate is arranged downwards, and its end is placed in the top of the upstream face of energy dissipating tail bank.
The central angle of the cancave cambered surface place fan-shaped section that meets water of described energy dissipating tooth bank is 60 °-65 °.
The central angle of the backwater cancave cambered surface place fan-shaped section of described energy dissipating tooth bank is 55 °-60 °.
Technique effect of the present utility model is:
The utility model adopts energy dissipating tooth bank to combine with watertight shutter, water guide web plate and weather board, and realize repeatedly concentrating energy dissipating, effect of energy dissipation is good; Its compact conformation, without the need to building longer protection-apron, reduces construction cost, not by the restriction in narrow place, and wide accommodation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, absorption basin; 2, energy dissipating tooth bank; 21, meet water cancave cambered surface; 22, backwater cancave cambered surface; 3, energy dissipating tail bank; 31, upstream face; 4, watertight shutter; 5, weather board; 6, water guide web plate; 7, water guide space; 8, support bar.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
As shown in Figure 1, the novel hydropower absorption basin structure of the present embodiment, comprise the absorption basin 1 being arranged at outlet structure escape works downstream, the water intake end of absorption basin 1 is with energy dissipating tooth bank 2, its discharge ends is with energy dissipating tail bank 3, energy dissipating tooth bank 2 is with cancave cambered surface 21 and the backwater cancave cambered surface 22 of meeting water, and the cancave cambered surface 21 that meets water seamlessly transits with the leading portion of absorption basin 1; The top of energy dissipating tooth bank 2 arranges watertight shutter 4, watertight shutter 4 is tilted to lower setting along the drainage direction of absorption basin 1, the lower end of watertight shutter 4 is with water guide web plate 6 and weather board 5, and weather board 5 is placed in the top of water guide web plate 6, with water guide space 7 between weather board 5 and water guide web plate 6.
Watertight shutter 4 and water guide web plate 6 are connected respectively by support bar 8 and absorption basin 1.
Water guide web plate 6 is tilted to lower setting, and its end is placed in the top of the upstream face 31 of energy dissipating tail bank 3.
The central angle of the cancave cambered surface 21 place fan-shaped section that meets water of energy dissipating tooth bank 2 is 60 °-65 °, and the central angle of its backwater cancave cambered surface 22 place fan-shaped section is 55 °-60 °.Because energy dissipating tooth bank 2 has the cancave cambered surface 21 that meets water of 60 °-65 ° degree, what namely have buffering current chooses angle, the current of the both sides and surface portion of letting out groove cross section can be provoked by energy dissipating tooth bank 2, flow rate of water flow is reduced to original about 1/4th very soon afterwards, and secondary reduces flow velocity under the stop of watertight shutter 4, when flowing to water guide web plate 6, due to cancellated barrier effect, the most finally steady flow, to downstream, thus reduces the fluctuation of current in absorption basin 1 greatly in absorption basin 1 and in water guide space 7.
The utility model adopts energy dissipating tooth bank to combine with watertight shutter, water guide web plate and weather board, and realize repeatedly concentrating energy dissipating, effect of energy dissipation is good; Its compact conformation, without the need to building longer protection-apron, reduces construction cost, not by the restriction in narrow place, and wide accommodation.
Above illustrated embodiment is better embodiment of the present utility model, only be used for conveniently the utility model being described, not any pro forma restriction is done to the utility model, have in any art and usually know the knowledgeable, if do not depart from the utility model carry in the scope of technical characteristic, utilize the utility model disclose the Equivalent embodiments changed or modify in the done local of technology contents, and do not depart from technical characteristic content of the present utility model, all still belong in the scope of the utility model technical characteristic.
