Изобретение относитс к ограждающим устройствам и может быть использовано дл защиты сооружений, стро щихс в поймах рек.The invention relates to enclosing devices and can be used to protect structures built in floodplains of rivers.
Известно тросовое ограждение дл защиты ото льда опоры ЛЭП, содержащее фундамент , верхний и нижний опорные элементы , на которых смонтированы огибаемые тросом ролики.Known cable fence to protect from ice pylons, containing the base, the upper and lower supporting elements, on which are mounted around the cable rollers.
Однако указанное ограждение выполнено в виде усеченной пирамиды и поэтому на ее боковых гран х возможно скопление льда, кроме того, оно выполнено неподвижным, что увеличивает напр жени в тросе и передачу его на опору ЛЭП, при нагромождении льда.However, this fence is made in the form of a truncated pyramid and therefore ice accumulation is possible on its lateral faces, moreover, it is made stationary, which increases the voltage in the cable and transfers it to the power transmission tower when ice is piled up.
Цель изобретени - уменьшение напр жени в тросе от действующих нагрузок и устранение скоплени льда.The purpose of the invention is to reduce the voltage in the cable from the actual loads and eliminate the accumulation of ice.
Дл достижени поставленной цели тросовое ограждение дл защиты ото льда опоры ЛЭП, содержащее фундамент, верхний и нижний опорные элементы, на которых смонтированы огибаемые тросом ролики, выполнено в виде усеченного конуса, при этом опорные элементы выполнены из подвижной и неподвижной обойм, между которыми установлены тела качени , а ролики к верхней опоре прикреплены посредством амортизаторов.To achieve this goal, the cable fence for protecting the power transmission line supports from ice containing the foundation, the upper and lower supporting elements, on which the rollers bend around the cable, is made in the form of a truncated cone, while the supporting elements are made of a movable and stationary holder, between which bodies are installed rolling, and the rollers to the upper support attached by shock absorbers.
На фиг. 1 - ограждение, общий вид; на фиг. 2 - разрез верхней опоры; на фиг. 313рез нижней опоры.FIG. 1 - fencing, general view; in fig. 2 - section of the upper support; in fig. 313 cut of the bottom support.
разрез нижней опоры.cut bottom support.
Тросовое ограждение дл защиты ото льда опоры ЛЭП содержит верхний опорный элемент 1, закрепленный на опоре ЛЭПCable guard for protection of the power transmission line from ice contains the upper support element 1 fixed on the power transmission line support
2, к которому при помощи амортизатора 3 подвещена пластина 4 с роликами 5 и нижний опорный элемент 6 с роликами 7. Ролики 5 и 7 огибают предварительно напр женный трос 8, на котором закреплен трос 2, to which, using a shock absorber 3, a plate 4 with rollers 5 and a lower supporting element 6 with rollers 7 are led. Rollers 5 and 7 bend around a pre-tensioned cable 8, on which a cable is fixed
,5 9. Каждый опорный элемент содержит подвижную 10 и неподвижную 11 обоймы. Неподвижна обойма нижнего опорного элемента закреплена на фундаменте 12. Удар при сталкивании льдины с тросовым ограждением см гчаетс тросом 8. Поворотные, 5 9. Each supporting element contains a movable 10 and a fixed 11 holder. The fixed cage of the lower support element is fixed on the foundation 12. The impact when pushing the ice with the cable fence is softened by the cable 8. Swivel
20 опорные элементы и амортизаторы, на которых установлены ролики, снижают напр жени в тросе от действующих нагрузок, а также исключают скопление льда у опоры ЛЭП.The 20 supporting elements and shock absorbers on which the rollers are mounted reduce the stress in the cable from the actual loads, and also eliminate the accumulation of ice at the power transmission tower.
