Further, second level buttress 8, the 3rd pole buttress 9 are disposed with from high to low after the first order buttress 6
With fourth stage buttress 10；Second level pulley track 7, two second level pulley rails are being installed described in four groups at the top of buttress
Being slidably installed between road 7 has the permeable cloth 11 of tail water, and the permeable cloth 4 of the abutment wall and the permeable cloth 11 of tail water are all disposed within cushion pool
12 surface.
Further, the height of the first order buttress 6 is higher than the height of abutment wall 2, first order pulley track 5 is tilted cloth
Put.According to trajectory nappe, parabolically form falls into riverbed downstream cushion pool, and the permeable cloth 4 of abutment wall can be from bottom to top from abutment wall
It is in tilted layout to first order buttress 6；The permeable cloth 11 of tail water can be in tilted layout to the third level from bottom to top from fourth stage buttress 9s
Buttress 8.
Further, the first order pulley track 5 includes roller 5-1, and the roller 5-1, which is slidably matched, is arranged on rolling
Inside groove 5-3, the fixed installation permeable cloth of abutment wall between roller arm 5-2, the roller arm 5-2 is installed between the roller 5-1.
Further, the structure of the second level pulley track 7 is identical with the structure of first order pulley track 5, and all adopts
Driven with motor.The permeable cloth 4 of abutment wall need to be erected highly to be provoked by the maximum of overflow under different periods, different operating modes and highly determined
It is fixed；The permeable cloth 11 of tail water need to erect the maximum height that height is impinged upon hydraulic jump after cushion pool by overflow under different periods, different operating modes
Degree determines, ensures the arrangement of permeable cloth 4 and permeable cloth 11 above overflow.
Further, first order pulley track 5 and second level pulley track 7 are equipped to be powered, the pulley on pulley track
Bar freely can advance or retreat with the rolling of two head sheaves in the case of energization, the permeable cloth 4 arranged on pulley track and permeable

Top；Current flow down from dam body 1, when hitting defrlector bucket 3, can produce a large amount of water smokes, are being provoked by the permeable cloth 4 of abutment wall
The source of water smoke tentatively reduces flood-discharge atomizing degree；Flow impact to the undermining of underwater bed cushion pool cheat when, can rise a large amount of
Water smoke, flood-discharge atomizing degree is further reduced by the permeable cloth 11 of tail water.
Further, when flood discharge is larger, the permeable cloth 11 of tail water is with the roller arm roller of second level pulley track 7 from trend
Upper slip, increase preventing atomization area, when flood discharge is especially big, roller can directly slide into first order buttress 6, when under flood discharge
Drop, roller is to abutment wall side and fourth stage buttress Slideslip, and permeable cloth shrinks with roller arm to be rolled, and its usable area reduces.
Further, during the flood discharge neutral gear phase, the roller slide downward of first order pulley track 5 is moved to abutment wall, and the second level is slided
The roller of wheel track 7 is slided down at fourth stage buttress 10, and the permeable cloth of this preventing atomization is all rolled, and can prevent bad weather etc.
Destroy, make the permeable cloth of this preventing atomization more durable in use.And the permeable cloth of this preventing atomization is located above overflow, prevents it by current scour
Cause bigger atomization, ensure that the service life of the permeable cloth of this preventing atomization.
Further, the permeable cloth of this preventing atomization is formed for the spacial framework functional high molecule material with strong hydrophilicity group
The permeable cloth of high-hygroscopicity resin, there is extremely strong water penetration, and cost is low, corrosion-free, pollution-free, renewable, can fully mitigate
Degree is changed in flood discharge five.
By chosen in flood discharge stream source and during multistage preventing atomization arrange, and the permeable cloth of this preventing atomization of flexible modulation
Preventing atomization size, mitigate downstream flood-discharge atomizing degree to greatest extent, save traditional preventing atomization process cost, flexibility
Height, it is workable.
