Abstract

Изобретение относитс к области эксплуатации резервуаров дл хранени жидких продуктов и предназначено дл ремонта эластичных резервуаров дл нефтепродуктов, преимущественно в полевых услови х. Цель изобретени - обеспечение надежной герметизации резервуара и расширение эксплуатационных возможностей устройства. Дл этого средство дл приведени внутреннего пластыр 2 (ВП) в рабочее положение выполнено в виде пластинчатых пружин и двуплечего рычага. ВП выполнен в виде пластины, шарнирно смонтированной на штыр х. Последние диаметрально противоположно расположены на гайке 4, установленной на разъемном стержне 3 дл ст гивани наружного 1 пластыр (НП) и ВП. Пластинчатые пружины смонтированы на штыр х. Двуплечий рычаг одним плечом контактирует с нижним торцом стержн 3. На втором плече рычаг имеет зацеп дл взаимодействи с окном ВП. На НП имеетс уплотнение в виде герметичного шланга 8, заполн емого сжатой рабочей средой из источника 10 при разрушении мембраны последнего игольчатым элементом 11. На внутренней поверхности НП установлены емкости дл вспенивающего материала, заполн ющего полость между НП и ВП после их ст гивани . Дл воздействи на игольчатые элементы источников дл подачи сжатой рабочей среды на НП с возможностью поворота относительно стержн 3 установлена втулка 14 с кулачком 17. Устройство позвол ет быстро и надежно ремонтировать большие эластичные резервуары в полевых услови х. 3 з.п. ф-лы, 5 ил.The invention relates to the field of operation of storage tanks for liquid products and is intended for the repair of elastic tanks for petroleum products, mainly in field conditions. The purpose of the invention is to provide reliable sealing of the tank and expanding the operational capabilities of the device. For this, the means for bringing the inner patch 2 (VP) to the working position is made in the form of plate springs and a double-arm. VP made in the form of a plate, hinged mounted on pins x. The latter are diametrically opposed on the nut 4 mounted on the detachable rod 3 for tightening the outer 1 patch (NP) and VP. Plate springs are mounted on pins x. The double-shouldered lever with one shoulder contacts the lower end of the rod 3. On the second shoulder, the lever has a hook to interact with the window VP. The NP has a seal in the form of a sealed hose 8 filled with compressed working medium from the source 10 when the membrane of the latter is destroyed by the needle element 11. Capacities for foaming material are installed on the inner surface of the NP, filling the cavity between the NP and VP after shrinking. To act on the needle elements of the sources for supplying the compressed working medium to the NP, the sleeve 14 with the cam 17 is installed with the possibility of rotation relative to the rod 3. The device allows you to quickly and reliably repair large elastic tanks under field conditions. 3 hp f-ly, 5 ill.

Claims

Claim

1. A device for sealing damage to tanks, containing a box-shaped outer patch with a perimeter seal, an inner patch, a means for tightening the patches in the form of a detachable threaded rod and a nut mounted on it, a sleeve located concentrically to the rod, means for bringing the inner patch into position and means for filling the cavity between the plasters with a foaming material, characterized in that, in order to ensure reliable sealing of the tank and expand operational x the device’s capabilities, a detachable threaded rod is made up of upper and lower parts pivotally connected to each other, and a nut is installed on its lower part, and the means for bringing the internal patch into working position are made in the form of plate springs mounted on the nut by diametrically opposite pins , and a two-shouldered lever pivotally mounted on the nut, in contact with one shoulder with the lower end of the rod and having a hook on the second shoulder for interaction with friction patch and the inner patch is formed as a plate pivotally mounted on pins and having a window for passage of the nut.

2. The device according to π. 1, characterized in that the seal is made in the form of a sealed elastic hose and connected to it through a destructible membrane of a source of compressed working medium with a needle element for breaking the membrane.

3. The device according to π. 1, characterized in that the means for feeding the expandable material is made in the form of a container for expanding material with a piston installed on the inner surface of the outer patch for displacing the latter and an elastic section on the wall facing the rod and connected to the container with an additional source of compressed working medium with a destructible membrane and needle * element to destroy the latter.

4. The device according to paragraphs. 2 and 3, characterized in that the sleeve is mounted on the outer patch with the possibility of rotation relative to the threaded rod and equipped with a wife cam for acting on the needle elements and a cutting element for breaking the elastic portion of the container for foaming material.
