Description
Technical field
The utility model relates to a kind of drain cavern structure, especially relates to a kind of drain cavern structure for rotational flow silo, belongs to Hydraulic and Hydro-Power Engineering Building Design building technology field.
Background technology
Larger in the intake-outlet discrepancy in elevation, and intake-outlet close together, or there are other buildings to arrange in the drain cavern design of impact, high speed water in hole fail to be convened for lack of a quorum in hole and export structure and underwater bed and bank slope cause erosion damage, and affect the safety of Adjacent Buildings, therefore, be necessary to seek the effective measures of first energy dissipating in hole.Generally, be the method for relatively commonly using by building a hole inward eddy energy dissipating drilled shaft elimination part energy.This energy dissipating drilled shaft can only make lower sluicing stream be issued to the effect of preliminary energy dissipating along the rotation of the energy dissipating drilled shaft borehole wall, but the high-velocity flow that carries larger dump energy still can impact silo bottom, form bottom current disorder, rapid, easily vertical shaft base plate, vertical shaft hole crossing with bottom cave of debouchure section and delivery port etc. are caused to erosion damage.
Utility model content
Technical problem to be solved in the utility model is: provides a kind of and can eliminate in a large number the more dump energy that high-velocity flow carries, thus the drain cavern structure for rotational flow silo of protection rotational flow silo bottom.
For solving the problems of the technologies described above adopted technical scheme be: a kind of drain cavern structure for rotational flow silo, the horizontal cave of debouchure that comprises rotational flow silo body and be communicated with described rotational flow silo body, bottom at described rotational flow silo body is also provided with energy dissipator, and the elevation of described energy dissipator bottom surface is lower than the elevation of the base plate of the described horizontal cave of debouchure.
Further, described energy dissipator is made up of to the pit of downward-extension described rotational flow silo body, and the elevation of the bottom surface of described pit is lower than the elevation of the base plate of the described horizontal cave of debouchure.
Further, described rotational flow silo body is rounded in the projection of its cross section.
Further, the bottom surface of described pit is to recessed spheric.
Further, the tangent connection of sidewall of the upper limb of the bottom surface of the described pit of spheric and described rotational flow silo body.
The beneficial effects of the utility model are: because the bottom at described rotational flow silo body is also provided with energy dissipator, and make the elevation of bottom surface of described energy dissipator lower than the elevation of the base plate of described horizontal flood discharging tunnel.Like this, through described rotational flow silo body eddy flow and under current after preliminary energy dissipating, more further eliminate remaining potential energy by described energy dissipator, thereby realize the object of the more dump energy that a large amount of elimination high-velocity flows carries.The elevation setting of the bottom surface of described energy dissipator is come lower than the elevation of the base plate of the described horizontal cave of debouchure, it is the water yield for a storage part enters in advance in described energy dissipator, increase aeration concentrater to form water cushion, and then make the high-velocity flow of letting out under postorder spin current vertical shaft body in the time entering described energy dissipator, reach the effect that effectively supplements energy dissipating, alleviate the impact of rotary water current to vertical shaft base plate simultaneously.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model for the drain cavern structure of rotational flow silo;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the B-B sectional view of Fig. 1.
In figure, be labeled as: rotational flow silo body 1, the horizontal cave of debouchure 2, energy dissipator 3, spheric 4.
Detailed description of the invention
As shown in Figure 1, Figure 2 and shown in Fig. 3, be that a kind of that the utility model provides can eliminate the more dump energy that high-velocity flow carries in a large number, thus the drain cavern structure for rotational flow silo of protection rotational flow silo bottom.The horizontal cave of debouchure 2 that described drain cavern structure comprises rotational flow silo body 1 and is communicated with described rotational flow silo body 1, bottom at described rotational flow silo body 1 is also provided with energy dissipator 3, and the elevation of described energy dissipator 3 bottom surfaces is lower than the elevation of the base plate of the described horizontal cave of debouchure 2.Because the bottom at described rotational flow silo body 1 is also provided with energy dissipator 3, and make the elevation of described energy dissipator 3 bottom surfaces lower than the elevation of the base plate of the described horizontal cave of debouchure 2.Like this, through described rotational flow silo body 1 rotate and under current after preliminary energy dissipating, more further eliminate remaining potential energy by described energy dissipator 3, thereby realize a large amount of objects of eliminating the more dump energy that high-velocity flows carry.The elevation setting of the bottom surface of described energy dissipator 3 is come than the elevation of the base plate of the described horizontal cave of debouchure 2, it is the water yield for a storage part enters in advance in described energy dissipator 3, increase aeration concentrater to form water cushion, and then make the high-velocity flow that postorder spin current vertical shaft body is let out for 1 time in the time entering described energy dissipator 3, reach the effect that effectively supplements energy dissipating, alleviate the impact of rotary water current to vertical shaft base plate simultaneously.
In above-mentioned embodiment, in order to simplify the structure of described energy dissipator 3, convenient construction, is set to the pit to downward-extension by described rotational flow silo body 1 by described energy dissipator 3, and makes the elevation of bottom surface of described pit lower than the elevation of the base plate of the described horizontal cave of debouchure 2.Like this, just can make described energy dissipator 3 build in the lump in the time being built into described rotational flow silo body 1, reach convenient object of building.In conjunction with rotational flow silo body 1 described in the prior art in the rounded design feature of the projection of its cross section, in order to improve effect of energy dissipation, simultaneously protect again described energy dissipator 3 not to be rotated as much as possible and under high-velocity flow erosion damage, the bottom surface of described pit is set to recessed spheric 4 structures, and make the upper limb of bottom surface and tangent connection of sidewall of described rotational flow silo body 1 of the described pit of spheric 4, reach improve along the 1 wall rotation of rotational flow silo body and under flow condition, alleviate impact and the pulsation of current to energy dissipator 3 base plates, realize the sufficient aeration of water cushion, reach the effect of more fully supplementing energy dissipating.Meanwhile, the stress condition of circular arc base plate is good, and structure is survivable, can reduce current pit is cheated the erosion attack risk of the structure upstream faces such as wall, bottom cave of debouchure section and outlet, makes flow regime of impeller outflow more stable, effectively improves high-velocity flow energy dissipation rate in hole.
