Description
(54) ШАХТНЫЙ ВОДОСБРОС(54) MINE WATER DISCHARGE
1one
Изобретение относитс к гидротехническому строительству, в частности к шахтным водосбросам.FIELD OF THE INVENTION The invention relates to hydraulic construction, in particular to mine spillways.
Известен шахтный водосброс, включающий кольцевую водосливную воронку, расположенную в кольцевом резервуаре 1.Known mine spillway, including an annular overflow funnel located in the annular reservoir 1.
Известен также шахтный водосброс, включающий кольцевую водосливную воронку , размещенную в выемке берега водоема и цротивоводоворотное устройство 2.Also known mine spillway, including an annular overflow funnel, located in the recess of the reservoir and counter-rotating device 2.
Недостатком этих устройств вл етс неравномерность подхода воды к водосливной воронке, привод ща к снижению пропускной способности водосброса.The disadvantage of these devices is the uneven approach of the water to the overflow funnel, resulting in a decrease in the throughput of the spillway.
Цель изобретени - увеличение пропускной способности за счет повышени равномерности расхода по периметру воронки .The purpose of the invention is to increase the throughput by increasing the flow uniformity around the perimeter of the funnel.
Эта цель достигаетс тем, что противот водоворотное устройство . выполнено в виде четырех криволинейных стенок, расположенных над гребнем воронки, причем угол ер между стенками, расположенными со стороны водоема, составл ет не более 180°, аThis goal is achieved by countering a whirlpool. made in the form of four curvilinear walls located above the funnel ridge, and the angle between the walls located on the water side is not more than 180 °, and
со стороны берега определ етс по формулеfrom the coast is determined by the formula
cf2 270 - ) - {0,693 + (0,666 ), где Н - расчетный напор над гребнем воронки; R - радиус воронки;cf2 270 -) - {0.693 + (0.666), where H is the calculated head above the funnel ridge; R is the funnel radius;
- угол между стенками, расположенными со стороны водоема. - the angle between the walls located on the water side.
Кроме того, водосброс снабжен направл ющими лопатками, установленными по 10 периметру воронки.In addition, the spillway is equipped with guide vanes installed along the perimeter 10 of the funnel.
На фиг. 1 изображен шахтный водосброс , вид в плане; на фиг. 2 - то же, продольный разрез.FIG. 1 shows a mine spillway, a plan view; in fig. 2 - the same, longitudinal section.
Шахтный водосброс включает кольцевую водосливную воронку 1, размещенную Mine spillway includes an annular spillway funnel 1, placed
15 в выемке 2 берега водоема и вертикальную шахту 3. Над гребнем 4 воронки 1 расположено противоводоворотное устройство, выполненное в виде четырех криволинейных стенок 5 и 6. Угол ср, между стенками 5 составл ет не более 180°, а длина стенок 5 равна 1,5 R, где R - радиус воронки 1. Угол cf между стенками 6 определ етс по формуле cf2 (270- ,) 0,693-f(0,666-), а длина стенок 6 равна R. По периметру.15 in the recess 2 of the shore of the reservoir and the vertical shaft 3. A counter-rotating device is located above the ridge 4 of the funnel 1, made in the form of four curved walls 5 and 6. The angle cf between walls 5 is not more than 180 °, and the length of walls 5 is 1, 5 R, where R is the funnel radius 1. The angle cf between the walls 6 is determined by the formula cf2 (270-,) 0.693-f (0.666-), and the length of the walls 6 is equal to R. Around the perimeter.
