Abstract
The utility model discloses a rectification energy dissipater with an arc-shaped and linear combined threshold. The rectification energy dissipater with the arc-shaped and linear combined threshold comprises a force dissipating pool which is arranged at the downstream side of a water gate. An arc-shaped energy dissipating threshold and a linear energy dissipating threshold are sequentially arranged on a base board of the force dissipating pool in the direction of water flow. The linear energy dissipating threshold is located at a water outlet end of the tail portion of the force dissipating pool. A middle protruding portion of the arc-shaped energy dissipating threshold faces the linear energy dissipating threshold. The rectification energy dissipater with the arc-shaped and linear combined threshold can enhance energy dissipating effect in low Froude number flood discharge and energy dissipation, so that the purpose that water flows out smoothly is achieved, and scour of the concrete base board and a downstream bed is reduced.
Description
Technical field
The utility model relates to a kind of energy dissipator, particularly relates to a kind of rectifying energy dissipator with arc and linear combination bank, belongs to the hydraulic engineering technical field.
Background technology
The energy dissipater is a kind of unnecessary kinetic energy of letting out torrent under outlet structure escape works or the drop structure of eliminating, and prevents or alleviates the engineering services that current are built the erosion damage of hydraulic structure and downstream rivers and canals thereof etc.Existing one-level linear absorption basin comprises sluice and is located at the absorption basin in the downstream of sluice, the single linear of being located at the afterbody water side of the absorption basin power bank that disappears; There is following shortcoming in the energy dissipator of this structure: under low not formula number during flood-discharge energy-dissipating, there is flow instability problem in lock chamber and the absorption basin, and when sluice moves, need flow-shape steady, to reduce the washing away of concrete floor and underwater bed, one-level linear absorption basin can not satisfy this kind needs.
The utility model content
At the deficiencies in the prior art, the purpose of this utility model is for a kind of rectifying energy dissipator with arc and linear combination bank is provided, adopt this energy dissipater can be low when not formula is counted flood-discharge energy-dissipating, strengthen effect of energy dissipation, and then the purpose that has flowed out, reduce current washing away concrete floor and underwater bed. with having reached that the water flows gently
For achieving the above object, the utility model adopts following technical scheme:
Rectifying energy dissipator with arc and linear combination bank comprises it is characterized in that the absorption basin in the downstream of being located at sluice: be disposed with one arc energy dissipating bank with linear energy dissipating bank in the base plate upper edge of absorption basin water (flow) direction; Described linear energy dissipating bank is positioned at the afterbody water side of absorption basin, and the middle protuberance of described arc energy dissipating bank is towards linear energy dissipating bank.
Realize that the purpose of this utility model can also reach by taking following technical scheme:
Realize that a kind of embodiment of the present utility model is: described arc energy dissipating bank, linear energy dissipating bank and absorption basin are the overall structure of one-time-concreting moulding.
Realize that a kind of embodiment of the present utility model is: described arc energy dissipating bank, linear energy dissipating bank and absorption basin are for adopting the overall structure of steel concrete one-time-concreting moulding.
The beneficial effects of the utility model are:
The utility model is by being disposed with one arc energy dissipating bank with linear energy dissipating bank in the base plate upper edge of absorption basin water (flow) direction, go out the stream back by arc energy dissipating bank and guarantee concentrating of current, and the Fu Luode number of section before improving downstream linear energy dissipating bank and jumping, can be low when not formula be counted flood-discharge energy-dissipating, strengthen effect of energy dissipation, and then the purpose that has flowed out with having reached that the water flows gently, reduce current to the washing away of concrete floor and underwater bed, the technical problem of fluidised form shakiness when having overcome existing single linear energy dissipating bank and can not subdue current and enter.

The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
Specific embodiment 1:
With reference to Fig. 1-Fig. 2, the described rectifying energy dissipator with arc and linear combination bank of present embodiment, the absorption basin 3 that comprises the downstream of being located at Segment gate 4 is disposed with one arc energy dissipating bank 1 with linear energy dissipating bank 2 in the base plate 31 upper edge water (flow) directions of absorption basin 3; Described linear energy dissipating bank 2 is positioned at the afterbody water side of absorption basin 3, and the middle protuberance 11 of described arc energy dissipating bank 1 is towards linear energy dissipating bank 2.
With reference to Fig. 2, described arc energy dissipating bank 1, linear energy dissipating bank 2 and absorption basin 3 are for adopting the overall structure of steel concrete one-time-concreting moulding.Described camber line energy dissipating bank should calculate different radius of curvature according to different gate clear span and different lock flows.
The utility model mainly solves the low Fu Shi number rough sledding of sluice flood-discharge energy-dissipating down, water (flow) direction in flood discharge, the energy dissipating bank of one camber line is set earlier, the Fu Luode number of section made that the bank current were more steady before energy dissipating bank by camber line shape went out the stream back and guarantees concentrating of current and improve downstream linear energy dissipating bank to jump.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion should belong within the protection domain of the utility model claim all.
