Description

новени  остальных стоек с дном. При достижении одним из ноплавков 5 нижнего ограничител  15 реакци  грунта будет передаватьс  всей конструкции опоры, что приведет к дифференцированию и заклиниванию остальных опорных стоек 9 в направл ющих обоймах 7 и 8. Опора установлена и готова к работе. Дл  подъема опоры на поверхность осуществл етс  продувка поплавков через трубопроводы 11. Вода выходит через отверсти  12 и опора приобретает положительную плавучесть.New racks with bottom. When one of the floats 5 reaches the lower limiter 15, the ground reaction will be transmitted to the whole support structure, which will lead to differentiation and jamming of the remaining support posts 9 in the guide holders 7 and 8. The support is installed and ready for operation. To raise the support to the surface, the floats are blown through the pipes 11. The water exits through the holes 12 and the support acquires positive buoyancy.

Предмет изобретени Subject invention

Донна  опора дл  грунтового снар да, включающа  раму с направл ющей втулкой, поплавки и опорные стойки, отличающа с   тем, что, с целью обеспечени  вертикальной установки снар да при сложном рельефе дна акваторий, опорные стойки телескопически смонтированы в поплавках, а внутри каждого из последних расположена балластна  емкость с клапаном-ограничнтелем.The bottom support for the soil projectile, which includes a frame with a guide sleeve, floats and support posts, is characterized in that, in order to ensure a vertical installation of the projectile with difficult topography of the water area, there is a ballast tank with a valve-limiting device.
