DEVICE FOR TYING ROPE TO TOWED UNDERWATER VEHICLES Russian patent published in 2008 - IPC B63B21/66 B63B21/56 

FIELD: transportation; shipbuilding.

SUBSTANCE: invention can be used in towed underwater vehicles, dropped platforms and in wells for oil and gas extraction. The device for tying rope to a towed underwater vehicle provides for electrical and mechanical contact between the towed underwater vehicle and the towing vehicle, which allows for free winding of the rope and protects the device itself from external effects. The device consists of two sealed chambers in line, made from strong protective case and inner sections, in which there is a powered built-in support of wires armouring, unit for sealing the cable inlet the section, unit for sealing the cable itself, rotating current collector and a pressure-sealed connector socket. The chambers are joined through bearing units, providing for rotation of the inner chamber with the powered built-in support of the cable and taking up tractional axial and lateral loads. The chambers are filled with an electrically insulating liquid and have compensators for varying the volume of the dielectric liquid. The device is joined in line to the body frame of the vehicle and through a pressure-sealed connector to the neck of the vehicle.

EFFECT: more reliable operation of the device.
