DIVER TOWER Russian patent published in 2015 - IPC B63C11/46 A63B35/12 

FIELD: transport.

SUBSTANCE: diver tower includes pressure-resisting hull, submersible electric motor, propulsor, accumulator batteries and is provided with light hull, waist belt, compressed-air reservoir and residual buoyancy control system. The pressure-resisting hull is made in the form of hollow cylinder with upper and lower semiballs the tops of which are connected by tube where propulsor is installed which propulsor is made in the form of hollow screw tube capable to rotate under power of reversible submersible electric motor. The light hull repeats shape of pressure-resisting hull and is installed with clearance h, envelopes surface of pressure-resisting hull and has holes on its side surface in the area of semiball bases. The residual buoyancy control system includes reservoir with holes in its bottom which reservoir is located in upper semiball of light hull, and ejector in the form of pipeline the inlet fitting of which is located in reservoir cavity and communicates via adjustable manual throttle with outlet fitting located in pipe behind propulsor. The compressed-air reservoir is installed in pressure-resisting hull and communicates by pipeline with reservoir cavity via adjustable manual throttle.

EFFECT: higher manoeuvrability of diver.
