A subsurface sampler includes a device for orientation at immersion, core barrel with shutoff mechanism. To provide sampling from large depths with guaranteed directed immersion of the device, decrease of sample wash out at lift to surface the orientation device comprises shaft that is placed at axis of the bypass ring and separate rods each of which is fixed in the upper section of the outer surface of the shaft with inclination in direction from it, the lower end of that one is rigidly fixed on the bypass ring and is equipped with armature and stabilization wing. The core barrel is placed in the shaft with possibility of motion along it, and shutoff element is arranged as leaf one, this is installed with possibility of closing the core barrel opening at instant of lift. |
