Description
Technical field
The utility model relates to field of water conservancy, especially a kind of water power catch-drain energy-dissipating structure.
Background technology
In field of water conservancy, in order to let out the unnecessary kinetic energy of torrent under eliminating outlet structure escape works or drop structure, prevent or alleviate the erosion damage of current to hydraulic structure and downstream rivers and canals etc. thereof, general needs builds the energy-dissipating structure eliminating water flow dynamic energy, is commonly called as " energy dissipater ".
The current conventional drainage ditch gradient is more slow, flow is less, and conventional general structure design can meet the demands, but along with draining the increase of flow, the increase of drop, the increase of the gutter gradient, the kinetic energy of ditch-water is along Cheng Zengjia, and conventional gutter can not meet energy dissipating needs, affect the safety of its structure, if destructurized, its drain function will be lost, and then affect the building safety around it.
Utility model content
Technical problem to be solved in the utility model is to provide one according to the flexible adjust structure of actual landform, and can effectively can eliminate the water power catch-drain energy-dissipating structure of the unnecessary kinetic energy that sluices.
The utility model solves the technical scheme that its technical problem adopts: water power catch-drain energy-dissipating structure, comprise Upstream section, at least one absorption basin and tract that the flow direction along current connects successively, the bottom of trench of described Upstream section is provided with Upstream section energy dissipating ladder, the bottom of trench of tract is provided with tract energy dissipating ladder, and described current are the energy dissipating by the buffering of Upstream section energy dissipating ladder, absorption basin and tract energy dissipating ladder successively.
Further, comprise the axis angle be made up of the Upstream section axis of Upstream section and the tract axis of tract, described axis angle span is 0 ~ 180 °.
Further, the water level of described Upstream section is higher than the water level of tract.
The beneficial effects of the utility model are: when practical application, and first the current with unnecessary kinetic energy flow to Upstream section, and in the flowing along described Upstream section, first current are cushioned step by step by Upstream section energy dissipating ladder thus consume the kinetic energy of current; Ensuing, current temporarily can be converged in absorption basin, the kinetic energy consuming the current from Upstream section that absorption basin is then relatively concentrated; Last, the current overflowed in absorption basin move on, the energy dissipating by the buffering of the tract energy dissipating ladder of tract, discharge until flow to exit.The present invention not only has the effect well eliminating the unnecessary kinetic energy of current, and the layout of Upstream section, absorption basin and tract can adjust flexibly with the actual needs of landform, improves the ability that the utility model adapts to objective landform complicated and changeable greatly.In addition, an ingenious part of the utility model design is water flow dynamic energy " to eliminate step by step ", not only do not need extra driving force completely, and the mode of described " eliminating step by step " reduces the impact failure of current to this energy-dissipating structure, is particularly useful among various water power catch-drain.

Be labeled as in figure: Upstream section 1, Upstream section energy dissipating ladder 11, Upstream section water (flow) direction 12, Upstream section axis 13, absorption basin 2, absorption basin water storage cavity 21, tract 3, tract energy dissipating ladder 31, tract water (flow) direction 32, tract axis 33, axis angle α.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Water power catch-drain energy-dissipating structure as shown in Figure 1, Figure 2, Figure 3 shows, comprise Upstream section 1, at least one absorption basin 2 and tract 3 that the flow direction along current connects successively, the bottom of trench of described Upstream section 1 is provided with Upstream section energy dissipating ladder 11, the bottom of trench of tract 3 is provided with tract energy dissipating ladder 31, and described current are the energy dissipating by the buffering of Upstream section energy dissipating ladder 11, absorption basin 2 and tract energy dissipating ladder 31 successively.
As shown in Figure 2, when current flow through Upstream section energy dissipating ladder 11, can along Upstream section energy dissipating ladder 11 step by step toward current downflow, general, suitably can design the difference in height of each Upstream section energy dissipating ladder 11, ensure that each Upstream section energy dissipating ladder 11 has the effect of buffer stop to the current from upper level ladder, thus play the effect eliminating water flow dynamic energy.This is equally also applicable to when designing the ladder height difference of tract energy dissipating ladder 31.For absorption basin 2, then be arranged at the stage casing of total, described absorption basin 2 mainly plays the effect of the elimination of comparatively being concentrated by the kinetic energy that the current from Upstream section 1 are also remaining, and from the current that absorption basin 2 overflows, when its kinetic energy has been far smaller than and has entered into absorption basin 2.
In order to adapt to the needs of different terrain, such scheme can also be selected: comprise the axis angle α be made up of with the tract axis 33 of tract 3 the Upstream section axis 13 of Upstream section 1, described axis angle α span is 0 ~ 180 °.Fig. 1 and Fig. 3 show respectively the structure when axis angle α value is respectively 180 degree and 0 degree, certain, and the span of axis angle α is 0 ~ 180 ° arbitrarily angled, and this needs the actual conditions depending on landform.This flexibility is also of the present utility model one large feature.
Certain, according to the design of general waterpower water power, the water level of preferred Upstream section 1 is higher than the water level of tract 3.Such current only need utilize its top-down flowing of conducting oneself with dignity, and the process of whole energy dissipating is without the need to extra power drive.
