Изобретение относитс к сельско- му хоз йству и может быть использовано при изучении поверхностного стока и водной эрозии почв.The invention relates to agriculture and can be used to study surface runoff and water erosion of the soil.
Целью изобретени вл етс упрощение конструкции, монтажа и обслуживани устройства дл учета поверхностного стока, а также повышение точности измерений,The aim of the invention is to simplify the design, installation and maintenance of a device for recording surface runoff, as well as improving the accuracy of measurements
На фиг. 1 представлено устройство , общий вид; на фиг. 2 - разрезFIG. 1 shows the device, a general view; in fig. 2 - section
А-А на фиг. 1.A-A in FIG. one.
Устройство включает тонкостенный водослив-водомер 1 с треугольным вырезом , снабженный направл юищми валиками 2, и цилиндрический стержень 3 из малорастворимого вещества в защитном корпусе 4. Защитный корпус 4 выполнен в виде отрезка металлической трубы с отверсти ми дл циркул ции воды, устанавливаемого вертикально в прудке перед водосливом.The device includes a thin-walled weir-water meter 1 with a triangular cutout, provided with guide rollers 2, and a cylindrical rod 3 of a slightly soluble substance in a protective housing 4. The protective housing 4 is made in the form of a piece of metal pipe with holes for water circulation, installed vertically in the pond before weir.
Верхний конец стержн 3 закреплен в крышке 5 корпуса 4, а нижний: конец находитс на одном уровне с нулем водослива 1.The upper end of the rod 3 is fixed in the lid 5 of the housing 4, and the lower one: the end is flush with the zero of the weir 1.
Устройство работает следующим образом .The device works as follows.
Талые и ливневые воды, стекающие с исследуемой водосборной площади , направл ютс валиками 2 к водосливу 1 и стекают через его вырез. На водосливе устанавливаетс определенный напор воды, завис щий от расхода стока. Величина его сначала нарастает, а затем, достигнув своего максимума, уменьшаетс . Стер (.The melt and storm waters flowing from the catchment area under study are directed by rollers 2 to weir 1 and drain through its notch. A certain water pressure is established on the weir, depending on the discharge flow. Its value first increases, and then, having reached its maximum, decreases. Stehr (.

жень 3 смачиваетс водой в период стока и постепенно раствор етс с поверхности. Продолжительность, смачивани измен етс по высотеGum 3 is wetted with water during runoff and gradually dissolves from the surface. Duration, wetting varies in height
5 стержн в соответствии с гидрографом стока, позтому степень растворени стержн по его высоте за период стока различна.5 rod in accordance with the flow hydrograph, therefore, the degree of dissolution of the rod along its height for the period of flow varies.
Измер диаметр стержн штангенциркулем на различных уровн х и вычисл уменьшение диаметра, можно, зна скорость растворени материала стержн , определить врем пребывани под водой любого из уровнейMeasuring the diameter of the rod with a caliper at various levels and calculating the reduction in diameter, it is possible, by knowing the rate of dissolution of the material of the rod, to determine the residence time under water of any of the levels.
5 и построить график изменени во 5 and plot the change in
времени напора на водосливе, по которому , .использу таблицу или тари- ровочную.кривую, стро т график изменени во времени расхода через водо20 слив. Последний график позвол ет судить о динамике расхода стока, определить максимальное значение его и объем стока.discharge time on the weir, according to which, using a table or a calibration curve, plot the time variation of flow through the discharge water. The last graph allows us to judge the dynamics of flow discharge, determine its maximum value and flow volume.
Скорость растворени стержней ° определ ют лутем тарировки опытных образцов с учетом температуры воды. Материал дл стержней подбирают по степени растворимости в зависимости от предполагаемого режима работы устройства: учета малого стока или ливневого, или накоплени информации за длительный период. В качестве материала стержн может быть использованы гипс, хлорид свинца, бура и другие малорастворимые соли и вещества .The dissolution rate of the rods ° is determined by the method of calibration of the test samples, taking into account the water temperature. The material for the rods is selected according to the degree of solubility, depending on the intended mode of operation of the device: taking into account low flow or storm water, or accumulation of information for a long period. Gypsum, lead chloride, borax and other poorly soluble salts and substances can be used as the material of the rod.
