Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
To enable above-mentioned purpose of the present utility model, feature and advantage more obvious understandable, below in conjunction with the accompanying drawings and tool
Body embodiment is described in further detail to the utility model.
As Figure 1-3, the utility model provides a kind of structure for adjusting release floodwatering flow distribution, and it is arranged on drain tank
Terminal position, including current lateral dispersion structure and current vertical direction dispersed structure.
The current lateral dispersion structure is that ligulate chooses bank 2, is arranged on the bottom plate position of drain tank end, is let out described in stretching
The side wall of tank and bottom plate end.Arrange that extending type chooses bank 2 similar to the ligulate of tongue shape, not only may be used on the bottom plate of drain tank
To increase the range of scatter of overflow, moreover it is possible to which the gradient that bank is chosen by adjusting ligulate casts angle to adjust overflow to aerial, makes water
Tongue avoids endangering building inherently safe away from buildings such as drain tanks.Ligulate chooses the setting of bank 2 so that bottom surface in drain tank
Current form the lower floor's current layer fully spread, lower floor's current layer is cross direction profiles.The current vertical direction dispersed structure
Drain tank is arranged on the concave side wall 3 of bank side, the current vertical direction dispersed structure is hung by the feet to hang patch bank 1 by the feet
Patch bank 1 is arranged on terminal position of the drain tank close to the concave side wall 3 of bank side.Hang the setting of the patch structure of bank 1 by the feet, make drain tank
In concentrate on and let out the current of geosynclinal concave side and overturn in vertical direction and fully spread, form the upper strata disperse water fluid layer fully spread,
And can change the direction of a stream of water, away from bank, avoid current side slope from causing seriously to wash away.Lower floor's current layer and upper water fluid layer
The flip shot flow velocitys of current is different, and flip shot angle is different, so that current flip shot, apart from different, lower floor's current flip shot distance is big
In upper strata current, during falling under a stream of water, upper and lower layer current intersect, collided in the air, consume the portion of energy of current,
Underwater bed and bank slope are washed away so as to weaken current.The direction of arrow in Fig. 1 and Fig. 2 is the side of the current in drain tank
To.
The side wall of the drain tank end is arc side wall, respectively concave side wall 3, convex side wall 4.Concave side wall 3 and convex side wall 4
Between connecting bottom board for distortion bottom plate 5, concave side wall 3 with distortion bottom plate 5 intersection elevation higher than convex side wall 4 with distortion bottom plate 5
Intersection elevation so that cross fall be present in concave side wall 3, the sluicing trough floor of 4 sections of convex side wall.
Concave side wall 3 in the arc side wall close to bank is identical with the arcuate shape steering of the convex side wall 4 away from bank,
It is away from bank direction that the arc side wall, which turns to, the flow direction in drain tank can be effectively adjusted, so that overflow is remote
Offshore side.For the concave, convex shape of concave side wall 3 in the present invention and convex side wall 4 is the runner of relative drain tank.
The method of the structural adjustment release floodwatering flow distribution of adjustment release floodwatering flow distribution of the present utility model, will go out drain tank
Overflow is adjusted to two layers, is comprised the following steps：
A, choose bank 2 and make to flow through ligulate in drain tank by being arranged on the ligulate of drain tank end and choose the current of bank 2 transversely
Fully diffusion, form lower floor's lateral current layer；
B, by be arranged on drain tank on the concave side wall 3 of bank side hanging by the feet patch bank 1 make in drain tank due to from
Mental and physical efforts cause to concentrate concave side current vertically to overturn abundant diffusion, form upper strata divergent flow layer；
C, the upper strata divergent flow layer in the lower floor's lateral current layer and step b in step a collides in the air, eliminates part
Flow energy, reduce the erosion damage degree of underwater bed and the degradation degree on riverbank.
Apply specific case in the utility model to be set forth principle of the present utility model and embodiment, the above
The explanation of embodiment is only intended to help and understands method and its core concept of the present utility model；Meanwhile for the one of this area
As technical staff, according to thought of the present utility model, there will be changes in specific embodiments and applications.To sum up
