TOWED NON-AUTONOMOUS UNDERWATER LOAD CARRIER Russian patent published in 2021 - IPC B63C11/52 

FIELD: diving technology.

SUBSTANCE: invention relates to the field of diving technology, in particular to underwater vehicles for the transportation of various goods and equipment. A towed non-autonomous underwater cargo container (TNAUCC) consists of a cylindrical body, in the cavity of which the bow, cargo and aft compartments and the buoyancy control system are located. The hull additionally contains a pivoting loop, a lock, a tail stabilization system during movement, a towing and anchoring device, a system of fastenings for carrying, for loading and unloading and transportation, as well as a mooring system and reflective elements. All compartments of the hull, except for the cargo compartment, are in communication with the outboard space and are designed so that if the TNAUCC is immersed in water, it freely penetrates into these compartments. The buoyancy control system is installed in the fore and aft compartments and contains a forward and aft tank of constant volume, high-pressure air cylinders with a reducer, valves: ventilation, medium-pressure air, filling, as well as a depth sensor, a battery, a control unit and a control panel. The cargo compartment is equipped with a sealing cover, which is the rear wall of the bow compartment, a system of fastenings and manual control valves for filling and ventilation, additional technological hatches, a cargo uncoupling system designed to protect the interior of the cargo compartment from the effect of external hydrostatic pressure during immersion in the entire operating range of depths. The nasal compartment is made with the possibility of reclining it on a pivoting hinge for access to the cargo compartment and closing it with a lock for sealing.

EFFECT: expansion of the arsenal of technical means, increase of maneuverability and speed of transportation, convenience of diving with loads, stopping at the required depth with a minimum consumption of compressed air.
