”SPRUT” FLOATING BARRIER AND FLOATING ELEMENT Russian patent published in 2023 - IPC F41H11/05 E02B15/06 

FIELD: barriers.

SUBSTANCE: the invention is intended to mark the boundaries of the restricted area in the water area and create a physical barrier to prevent the penetration of surface intruders (watercraft with a displacement of up to 4 tons) and underwater intruders at a depth of up to 10 meters into the water area of the protected object. A floating barrier “Sprut” is proposed, consisting of floating sections, each of which includes at least two floating elements connected in parallel by means of a power frame and connected in series with each other using detachable movable terminal connectors, a surface barrier structure with rack-holders, underwater barrier structure with an underwater barrier network, whereas between the two floating elements a central beam is introduced, the ends of which are rigidly connected to the power frame, the surface barrier structure is made in the form of catcher cables passed through collapsible guide elements on rack-holders mounted on the central beam power frame, and the barrier underwater structure is installed on the beam of the central power frame in the underwater part, the rack-holders are configured to tilt when the catcher cables are tensioned, whereas each detachable movable terminal connector is made in the form of a metal connecting plate with holes at the ends, located in vertical plane and freely fixed in a loop with its end through a hole at the end of the power frame, and two limiter chains fixed at the ends of the power beams of floating elements, providing sagging of the limiter chains when bending and turning the floating sections in the line of the floating barrier, and protective bumpers are installed on the power frame. A floating element for the barrier is also proposed.

EFFECT: creating a floating barrier with increased survivability, water resistance, strength and increased resistance to UV radiation.
