Description

The invention relates to the field of diving equipment, and in particular underwater vehicles of a permeable (“wet”) type for delivering a crew in light-diving equipment and payload to the area of the diving operations.

Given the life cycle of the transporter, it becomes necessary already at the design stage to take into account the possibility of changing external conditions, including not only design and technical, but also production, operational, and socio-political circumstances. Changes can affect the design of the transporter in different ways, taking into account the fact that the transporter is configured for specific customer tasks. Such a technological model for creating new models of underwater equipment, focused on solving specific problems, is very costly and time-consuming. Based on the foregoing, it seems appropriate to determine the configuration of the carrier, and then establish the rules for the integration of removable payloads for established tasks. Moreover, the payload for the carrier in this application (in the claimed technical solution) should be understood as AUV as a means to perform specific tasks in ensuring the effective implementation of diving operations.

The device of four local transporters of divers is known. The device of the four-seater transporter (group transporter) of divers "Grape", (V.P. Troshin, P.V. Troshin "From a diver to an ichthionaut," Publishing House St. Petersburg, St. Petersburg State Technical University, 2004, p. 283-286.) The transporter of the divers has a torpedo-shaped body in which the propulsion and propulsion system (DDK) is arranged in series, made in the form of two helical columns of the left and right sides, which are retractable into the housing niche when they are rotated 90 ° around the vertical axis, the device remote control compartment, battery and cargo container. Divers lie on the carrier on top.

The disadvantages of this analogue are:

- the limitations of its use, since it does not provide for the placement of additional payload;

- the presence of one DDK does not allow for its depth maneuvering without creating trim, which negatively affects the performance of divers.

Also known is the "Transporter of Divers" (patent RU No. 2458816, IPC G06F 12/16, published on 08/20/2012, bull. No. 23). The diver’s transporter contains a torpedo-shaped hull in which hydroacoustic equipment, a bow differential-equalization tank, a bow-propulsion complex made in the form of two helical steering columns of the left and right sides, retracted into the niche of the light body when turning around the vertical 90 ° axles, hinged fairing, instrument compartment with remote control, battery compartment, cargo compartment, aft trim tank and a compartment with a harpoon type anchor and a high-pressure air cylinder. Known transporter is the closest in technical essence to the claimed device and adopted as a prototype.

The disadvantages of the prototype are:

- the presence of only a bow DDK does not allow the conveyor to maneuver in depth without creating trim angles (up to ± 10 - 15 °), which creates real inconvenience for divers lying on its hull, thereby significantly reducing their performance;

- the transporter is not intended to solve several problems at once, since it does not provide for the placement of additional payload;

- the presence of only two differential leveling tanks does not allow you to quickly set the conveyor to a given level of height above the ground and make its sign;

- lack of additional energy reserves that could be used in critical situations.

The listed disadvantages limit the functionality of the transporter of divers and reduce the effectiveness of its use.

The basis of the proposed invention is the task to eliminate these shortcomings and to provide enhanced functionality of the transporter, for example, while transporting divers and carrying out the following important activities: lighting the situation in the area of performing tasks and on the route; delivery of payload to different points by different routes to the areas of work; environmental monitoring; protection of divers in the area of work.

The problem is solved in that the diver’s transporter containing a torpedo-shaped body, in which sonar equipment, a bow differential-equalization tank, a bow propulsion and propulsion system made in the form of two helical columns of the left and right sides, are retractable, are arranged sequentially from the bow to the stern. housing niche when rotated around the vertical axis by 90 °, hinged fairing, instrument compartment with remote control, high-pressure cylinder, battery compartment, g Uzes compartment aft trim balancing tank-compartment and the armature harpoon type and high-pressure air cylinder, is configured as a support autonomous underwater vehicle. For this, in the aft part of the diver’s transporter’s hull, in its diametrical plane, a wet-type hangar equipped with a docking module was made for placing an autonomous uninhabited underwater vehicle in it with the possibility of rigid fixation of its position and automatic undocking from the diver’s transporter. In addition, the diver’s transporter is additionally equipped with an identical bow-propulsion system with a stern-propulsion complex located in a niche made in the diver’s transporter’s housing between the battery compartment and the cargo compartment.

In addition, the task is also solved by the fact that the transporter of the divers is additionally equipped with an average differential equalization tank located between the high-pressure air cylinder and the battery compartment.

In the claimed underwater vehicle, the common essential features for him and for his prototype are:

- a torpedo-shaped body, in which are sequentially arranged from bow to stern

- sonar equipment;

- nasal differential equalization tank;

- nasal propulsion system, made in the form of two helical columns of the left and right sides, retractable in the niche of the housing when rotated around the vertical axis by 90 °,

- folding cowl

- instrument compartment with control panel,

- high pressure cylinder,

- battery compartment,

- cargo compartment

- feed differential equalization tank,

- compartment with harpoon type anchor and high pressure air cylinder.

A comparative analysis of the essential features of the claimed underwater vehicle and its prototype shows that the first, unlike the prototype, has the following significant distinguishing features:

- the diver’s transporter is designed as a carrier of an autonomous uninhabited underwater vehicle, for which a wet hangar equipped with a docking module for placing an autonomous uninhabited underwater vehicle with the possibility of rigid fixation of its position and automatic detaching from the transporter is made in the aft part of the diver’s transporter’s hull divers

- the diver’s transporter is additionally equipped with an identical bow-propulsion system with a stern-propulsion complex located in a niche made in the diver’s conveyor housing between the battery compartment and the cargo compartment;

- the transporter of the divers is additionally equipped with an average differential equalization tank located between the high-pressure air cylinder and the battery compartment.

Distinctive features of the proposed solution perform the following functional tasks to achieve the desired technical result:

- the transporter as an AUV carrier eliminates the need to develop and manufacture similar additional devices (transporters) for each specific task separately at the same time;

- equipping the conveyor with an additional propulsion and propulsion system (DDK), consisting of helical propellers included in the stern of the conveyor, allows it to be maneuvered in depth without creating a trim (i.e., on an even keel).

Based on the foregoing, we can conclude that the set of essential features of the claimed invention has a causal relationship with the achieved technical result, i.e. due to this combination of essential features of the invention, it became possible to solve the problem. These essential features that distinguish the declared transporter of divers from the prototype, together with the features common to him and the prototype, ensure the achievement of the claimed technical result in all cases to which the scope of legal protection applies.

The technical result is the creation of a transporter of divers as an AUV carrier, released from a torpedo tube of a submarine and ensuring the fulfillment of various tasks, by using at the first stage of application the entire transporter as a whole, and then part of it - an autonomous uninhabited underwater vehicle (AUV). Using AUV, which is structurally part of the transporter, allows you to perform additionally the following tasks:

- to illuminate the situation in the area of performance of tasks and on the route of the transporter;

- carry out the delivery of payload to different points by different routes to the areas of work;

- carry out environmental monitoring;

- carry out sonar resistance (GPA);

- protect divers in the area of work.

The invention is illustrated by drawings, where in FIG. 1 is a perspective view of a diver carrier from its side, FIG. 2 is a schematic representation of AUV; FIG. 3 is a top view of a diver’s conveyor, and in FIG. 4 cross section of the stern of the conveyor.

The diver’s transporter comprises a torpedo-shaped body 1, in which hydroacoustic means 2 are arranged sequentially from bow to stern, bow differential trim equalization tank 3, bow DDK 4, made in the form of two screw-steering columns of the left and right sides, which are retracted into the housing niche when turning around the vertical axis with the help of a rotary mechanism 5. In the middle part of the conveyor body 1 there is an instrument compartment 6 with control system equipment and a control panel, a hinged fairing 7, a cylinder 8 in high pressure air, medium differential equalization tank 9, compartment 10 of the battery. In the aft part of the conveyor’s hull 1, the aft DDK 11 is placed, made in the form of two screw-steering columns of the left and right sides, which are retracted into the aft niche of the hull 1 when turning around the vertical axis using the rotary mechanism 12. There is also a hangar 13 in the aft of the hull 1 wet type to accommodate the payload in it in the form of AUV, cargo compartment 14, stern trim leveling system 15, compartment 16 with a harpoon type anchor and high pressure air tank. Additionally, the drawing shows 17 - AUV.

Additionally included in the towing vehicle aft DDK 11 (together with the bow DDK 4) are controlled (both in automatic and in manual modes) individually for each rotor column, receiving commands from the control panel from the instrument compartment 6. Due to this, a new important property is achieved transporter - changing the immersion depth (i.e. depth maneuvering) without changing the trim angle (i.e., on an even keel). With this maneuvering, the divers lying on the body 1 of the transporter do not receive additional overloads and retain power to complete the tasks.

In the aft part of the transporter’s hull 1, a wet-type hangar 13 is made to accommodate a payload in it in the form of AUVs. The placement of the AUV in the hangar 13 is carried out manually by divers, and the fixation of its position in the hangar is carried out automatically. By means of a docking module (not shown in the drawing) installed in the hangar 13, the AUV is connected to the conveyor control systems. AUV control system is integrated into the conveyor control system. Docking AUV from

transporter is performed automatically according to the control program or at the command of the operator. Program - a task (i.e. a mission) is entered into the AUV by the operator from the control panel of the instrument compartment 6. AUV operates independently according to a given program, regardless of the carrier.

The presence of the ANPA 17 battery docked to the transporter, if necessary, allows to increase the range and speed of the conveyor.

The device operates as follows. After the release of the transporter from the torpedo tube of a submarine, divers leave the adjacent torpedo tube and are fixed lying on the surface of the hull 1 of the transporter. The driver-operator, upon a signal from the control panel of the instrument compartment 6, unfolds the bow DDK 4 and the aft DDK 11 and makes it sign without a move using trim-leveling tanks 3 and 9, 15. Then the conveyor displays to a predetermined depth. On the move of the transporter, control over the course, speed and depth is carried out automatically in accordance with the specified program or by the operator manually. Control signals are received from the control panel from the instrument compartment 6. During the movement of the conveyor, the hydroacoustic means 2 operate in the mode of ensuring navigational safety and lighting of the underwater environment. After the conveyor arrives at the desired point in the specified region, the operator-driver of the conveyor through the control panel of the instrument compartment 6 enters the necessary mission data from the task library into the AUV control system and automatically unmounts it from the transporter's hangar 13. Then the divers put the transporter on the ground or set at a predetermined height relative to the ground and fix this position by means of an anchor 16 of the harpoon type at this point. Now each of the underwater objects (AUV 17 and the transporter), being independent, carry out tasks each according to their plan. At the same time, the transporter of divers performs, as a rule, the main task, and the AUV is auxiliary.

Depending on the situation, the driver-operator of the transporter has the opportunity to enter the task program into the AUV control system at any stage of the conveyor’s following the task and undock the AUV at the desired point in the route to continue on its own to the area assigned to it and carry out the work planned by the program.

The proposed technical solution allows you to expand the functionality of the transporter and increase the efficiency of tasks for divers.
