Description
В подн том положении затвора крышка 10 не подверл ена внешним силовым воздействи м . Полностью перекрыва желоб 9, она преп тствует засорению его мусором , балластом, снегом и т. п. Благодар наличию выпуклости средн часть крышки (вдоль оси пути) несколько возвышает ( над уровнем верха желоба,-поэтому на среднюю часть крышки также не попадает мусор.In the raised position of the shutter, the cover 10 is not subjected to external force effects. Chute 9 is completely blocked, it prevents debris from clogging it with debris, ballast, snow, etc. Due to the bulge, the middle part of the lid (along the axis of the path) slightly elevates (above the top of the gutter), so there is also no debris on the middle part of the lid.
Опуска сь с полотном затвора 5, фасонный брус 6 нажимает на среднюю часть крышки 10 и вдавливает ее внутрь желоба 9. При этом крышка раст гиваетс и не преп тствует опусканию затвора в проектное положение, а мусор под нижнюю кромку бруса 10 не попадает.Descending from the shutter web 5, the shaped bar 6 presses the middle part of the lid 10 and presses it inside the gutter 9. At the same time, the lid expands and does not prevent the shutter from lowering into the design position, and debris does not fall under the lower edge of the beam 10.
При очередном подн тии затвора крышка 10 распр мл етс за счет сил упругости и восстанавливает свою выпуклость, отбрасыва на периферийную часть скатившиес на нее в момент опускани затвора частицы мусора или снега.When the shutter is raised again, the lid 10 expands due to the elastic forces and restores its bulge, throwing particles of debris or snow onto the peripheral part of the slide that is pulled onto it at the moment of lowering the shutter.
Благодар наличию упругой крышки, выполненной в виде выпуклой диафрагмы, перекрываюшей желоб, отпадает необходимость в посто нном надзоре за состо нием желоба и в его очистке от мусора и снега.Due to the presence of an elastic cover made in the form of a convex diaphragm overlapping the gutter, there is no need for constant supervision of the state of the gutter and its cleaning from debris and snow.
Использование изобретени позвол ет сократить затраты на эксплуатацию затвора на 30-50% и одновременно повысить надежность его работы.The use of the invention allows to reduce the cost of operating the shutter by 30-50% and at the same time increase the reliability of its operation.
