DEVICE FOR FLOATING DEVICE SEPARATION INTO PRESSURE-TIGHT COMPARTMENTS Russian patent published in 2019 - IPC F16B2/16 B63B22/08 B63G8/34 

FIELD: ocean engineering.

SUBSTANCE: invention relates to underwater equipment and can be used in drifting autonomous hydroacoustic instrument. Proposed device comprises sealed power casing consisting of compartments and buoy compartments, piston and wedge planks. Separation device is made in the form of a remote-controlled detachable structure and consists of a bulkhead. Bulkhead is made in the form of disc with wide rim, having on external cylindrical surface stepped annular groove with longitudinal slots, along axis of which in bulkhead there are blind holes with installed in them springs, and two flats diametrically located in the annular groove zone. Piston is tightly installed in stepped hole by means of sealing elements arranged in annular grooves of cylindrical surface of piston, on one end surface of which there is a cone, and on the other – a chamfer. Piston cone protrudes above bulkhead flattening surface, and drain channel is located between piston sealing elements. Wedge bars are hinged in grooves provided on outer surface of housing buoy compartment, and enter lengthwise grooves and step annular groove bulkhead, wedge planks are squeezed by band installed in annular groove bulkhead. Band consists of two belts and a pin; at the ends of one band there is a pad and a fork with a conical hole; at the ends of the other band there is an overlay and a lug with a conical hole; a cone of the piston enters the aligned conical holes of the assembled fork with the eye. Ends of straps with straps have holes, which are interconnected by tension pin.

EFFECT: higher reliability of device for separation of floating instrument into sealed compartments while in water.
