Description

 The invention relates to the field of underwater technology and, in particular, to technology for performing various underwater technical works (search, diving, rescue).

At present, in Russia and in other countries there are a large number of types of subsea-submarine systems operated and under development that are autonomous (receiving power supply and cabled from a carrier vessel), including:
- Uninhabited underwater telecontrol vehicles having a propulsion-steering complex, television, sonar and navigation equipment, systems, manipulators and other devices. These devices, called uninhabited underwater vehicles (NPA) or ROV, are designed to perform search and survey work, as well as to perform various underwater technical works using manipulators without the use of diving labor.

 - Inhabited self-propelled diving bells intended for the delivery of divers to the ground, ensuring the performance of work by divers on the ground, with the supply from the bell to the divers through the hoses of gas breathing mixtures, hot water for heating the divers, etc. and ensuring return of divers to the decompression complex of the carrier vessel. These diving bells are equipped with propulsion systems, which makes it possible for divers to work not only directly under the carrier vessel, but also in a certain area remote from it.

 - Rescue self-propelled bells designed to save the crews of sunken submarines in the “dry” and “wet” ways. These bells are equipped with propulsion systems, docking shafts to ensure docking with coaming sites of emergency submarines, receiving submariners into the bell in a “dry” way and delivering them to the carrier ship.

 - Inhabited self-propelled observation cameras equipped with propulsion systems, visual observation equipment (portholes, underwater periscopes, television cameras) designed to search and examine underwater objects.

 When performing specific underwater technical works on the same underwater object, it is sometimes required to use several types of tethered self-propelled technical equipment, which increases the cost of operations.

 The aim of this invention is to create a multifunctional tethered (receiving electricity from a carrier vessel) complex for performing various underwater engineering works (MKTPR) (diving, rescue, search and survey, etc.).

 This goal is achieved by the fact that the design of the immersion module MKTPR consists of several detachable blocks, the first of which is a self-propelled submersible platform of the ROV type, and the others are functional blocks mounted on the platform. At the same time, the type of functional block installed on the platform depends on the type of upcoming underwater technical works (diving, rescue, search and survey, etc.).

 The closest analogue of this invention can be considered the design of a tethered self-propelled diving bell company Bruker Meerestehnik, Germany (see abstracts "Shipbuilding. Naval equipment", 1985, 2, p. 115, 116; 9, p. 103; 12, p. .126, 127).

 The disadvantage of this bell is the impossibility of replacing the diving bell in the submerged module with another functional unit (rescue, search and survey, etc.), which reduces the bell’s capabilities and requires, if necessary, the implementation of rescue and search and survey works using other devices, which in turn, increases the cost of complex underwater engineering.

 In FIG. 1 shows a diagram of a first block of an immersion MKTPR module. The block consists of a platform 1 with installed on it longitudinal and transverse movement 2 and vertical movement 3, trim tanks 4, leveling tanks 5, manipulators 6, television cameras 7, underwater lights 8, antennas for navigation and hydroacoustic equipment 9, cable for receiving electric power 10, power converters 11, sealed electrical connectors 12, a rod for securing the cargo cable 13. This unit can be used independently, as it is uninhabited underwater vehicle (NPA) type ROV.

 When installing and securing functional blocks (a diving bell, diving and rescue bell, observation camera, etc.) on the first block of the immersed module and connecting the power systems of the functional blocks through sealed electrical connectors 12 to the power system of the MKTPTR platform, it can be used (respectively) to perform diving and rescue operations for the evacuation of personnel of the emergency submarine in the "wet" way (when installing a diving bell), or rescue operations for the evacuation of personnel of the avar submarine “dry” and “wet” methods (when installing a diving and rescue bell), or search and survey work (when installing an observation camera).

 In FIG. 2 is a diagram of the MKTPTR submersible module, where a diver and rescue bell 14 is installed as the second block of the submersible module, having a robust housing 15 for accommodating divers and rescued divers, a hatch 16 with a cover for entering (leaving) divers, receiving rescued divers and docking with decompression cameras of the carrier vessel for decompression of divers and rescued submariners (if they were under pressure in the emergency submarine), a removable docking shaft ("suction chamber") 17 for docking the bell with a coaming-plane with emergency submarines, cylinders with stocks of compressed gas 18 for divers, pressure connectors 19 for receiving power to the bell and fencing 20, designed to fasten equipment from the outside of the casing and protect it from mechanical damage.

 MKTPTR in this configuration can, in addition to the work entrusted to the ROV (sonar and television search, survey of underwater objects and underwater work using manipulators), perform diving and rescue (“dry” and “wet” ways) work. At the same time, the operational characteristics of the MKTPR and hydrometeorological conditions under which it can be operated (sea state, speed of undercurrents) will not be worse than that of similar technical means having a submersible module of "integral" design.

 However, when a functional module is removed from the ICTR and used in the ROV mode, which has a significantly lower displacement, its operational characteristics and hydrometeorological conditions under which it can be used will be significantly higher than its analogues.

 Other configurations of the second block of the immersion module MKTPR are also possible. So the docking shaft ("suction chamber") 17 is removable and when it is removed, work to rescue the crews of sunken submarines by the "dry" method using MKTPR can not be performed. When replacing the diving and rescue bell with an observation camera (not shown in the drawings), which is a strong capsule with an upper entrance hatch and installed visual devices (portholes, telescopes, underwater observation periscopes), MKTPR will be designed for search and survey work, as well as performing underwater technical work with the help of manipulators.

 In general, the MKTPTR is capable of performing all the functions inherent in the above-mentioned non-autonomous underwater equipment.
