Description

The utility model relates to the means of providing diving and underwater technical works, in particular to mobile complexes of diving equipment, and can be used in hard-to-reach, shallow-water places where a specialized vessel with diving equipment cannot approach.

Known mobile complex diving equipment (diving station PRS-VM), containing two modules [1]:

a module for diving descenders, located in the body of a van;

module of divers life support system in a decompression pressure chamber located in a van-trailer.

The disadvantages of this mobile diving equipment complex (diving station) include the fact that its design does not allow:

1) to use diving equipment working with artificial respiratory gas mixtures (GVD), since the mobile complex (diving station) is composed only of air cylinders and compressors;

2) to ensure the work of ventilation of the pressure chamber on a closed cycle, which requires periodic replenishment of the gas medium of the pressure chamber with oxygen, and also use oxygen in the pressure chamber to treat specific diving diseases, since the mobile complex (diving station) is not equipped with an oxygen system;

3) use a mobile complex (diving station) for special works on demining the water area, since its hull structures and equipment are made of magnetic materials;

4) to quickly use the mobile complex (diving station) for its intended purpose, as well as transport it to remote areas and place it on different carriers due to the presence of two large-sized modules in it.

The means for providing diving descents and the decompression pressure chamber with the life support system form a single module, inside which air compressors with cylinders are placed, as well as the pressure chamber and its life support system are separated into separate closed circuits, and a semi-closed or open ventilation is used as the ventilation chamber of the pressure chamber.

The disadvantages of this mobile diving equipment complex include the fact that its design does not allow:

1) use diving equipment working with artificial breathing gas mixtures (GVD), since the station has only air cylinders and compressors in its composition;

2) to ensure the work of the ventilation of the pressure chamber on a closed cycle, which requires periodic replenishment of the gas medium of the pressure chamber with oxygen, and also use oxygen in the pressure chamber for the treatment of specific diving diseases, since the diving station is not equipped with an oxygen system;

3) to use the station for special works on demining the water area, since the hull structures and equipment of the complex are made of magnetic materials.

The task of the utility model is to expand the technical capabilities of the mobile diving equipment complex (hereinafter - the mobile complex).

The task is achieved by the fact that in a mobile diving equipment complex containing a container, inside of which there are facilities for providing diving descents, air cylinders, an air supply console into the pressure chamber and its discharge into the atmosphere, a decompression pressure chamber with a life support system including air compressors located in a dedicated indoors, means of ventilation of the pressure chamber and air conditioning, according to the utility model:

one oxygen booster compressor is located in a dedicated room, and one cylinder with oxygen and a breathing gas mixture, oxygen supply and preparation of a breathing gas mixture, pipelines and fittings are additionally placed;

that the life-support system of the pressure chamber is additionally equipped with devices for the dosed supply of oxygen and individual breathing with oxygen with a control panel for feeding it into the pressure chamber;

The technical result from the use of the invention is to expand the functionality of the mobile complex, increase the efficiency and safety of its operation.

A schematic general view (side view) of the described mobile complex is shown in FIG. one.

The mobile complex consists of a container 1, an oxygen boosting compressor 2, an oxygen cylinder 3, an oxygen supply shield 4, a gas breathing gas cylinder 5, a DHS 6 preparation shield, a decompression pressure chamber 7, an oxygen control panel 8 for the pressure chamber, an individual oxygen breathing device 9, devices for supplying oxygen to the pressure chamber 10, means (unit) for closed ventilation and cleaning the gas medium of the pressure chamber 11, cylinders with a reserve of compressed air 12, a panel for supplying air to the pressure chamber and resetting it into the atmosphere 13, the air conditioner to create comfortable conditions in the container 14, folding diving ladder 15. At the same time, the oxygen booster compressor 2, one each with oxygen 3 and a breathing gas mixture 5, oxygen supply boards 4 and preparing a respiratory gas mixture 6, are placed in a dedicated room 16 of the container 1. A pressure chamber 7, equipped with individual oxygen breathing devices 9 and dosed supply of oxygen 10, means of closed ventilation and cleaning of the gas environment 11, as well as a compressed air system, including The cylinders 12, the compressed air supply panels 13 and the oxygen supply control 8 to the pressure chamber are placed in another room 17 of the container 1. Both rooms of the container 1 are equipped with supply and exhaust ventilation 18, fire alarm system 19, oxygen monitoring devices 20, and an outboard supply system water for cooling cylinders 21 in case of fire.

The container can be equipped with a filter 22 for filling cylinders with compressed air, suitable for diving breathing, which is located in room 17.

Container 1 is the carrier structure of the mobile complex and can be placed temporarily or permanently on any type of carrier (car, ship, ship, drilling platform, tug, ferry and other craft) and promptly delivered to the place of diving and underwater technical work or installed on unequipped coast.

Mobile diving equipment works as follows.

During the operation of diving equipment operating on artificial gas mixtures, including special purpose military equipment, the mobile complex uses an oxygen system and a DHS preparation system consisting of:

oxygen booster compressor 2 with an operating pressure of 20.0 MPa;

cylinder 3 for storing oxygen with a working pressure of up to 20.0 MPa and a capacity of 80 liters;

4 oxygen supply panel with fittings and pressure gauges;

cylinder 5 for the storage of DHS with a working pressure of 20.0 MPa and a capacity of 80 liters;

shield 6 preparation of DGS with valves and pressure gauges.

To replenish the supply of oxygen outside the container 1, a transport cylinder with gaseous oxygen is installed, which is connected to the oxygen system of the complex by means of removable pipelines available in the package bundle. Then, using an oxygen boosting compressor 2, oxygen from the transport cylinder is pumped to the standard cylinder 3, in which a pressure of 20.0 MPa is created, and to prepare DGS, oxygen from the cylinder 3 is fed through the oxygen supply shield 4 to the DGS shield 6 and further to the cylinder 5 to create the required composition DGS.

For charging diving breathing apparatus (VDA) cylinders, oxygen and DHS are used, for which oxygen from balloon 3 through the oxygen supply shield 4, as well as DHS from balloon 5 through the DHS preparation shield 6 is fed to the charging hose fitting of the BCA balloons.

To ensure the efficiency and safety of decompression and therapeutic recompression of divers in the pressure chamber 7 are used:

remote control oxygen supply 8 in the pressure chamber 7;

a device (mask) of individual breathing with oxygen 9 and the subsequent removal of oxygen outside the pressure chamber;

a device for supplying oxygen to the pressure chamber 10 to replenish the oxygen content in its gaseous environment;

means (unit) of the closed ventilation of the pressure chamber 11, which ensures the homogeneity of the gaseous medium due to the flow created by the electric fan built into it, as well as cleaning the gaseous medium from carbon dioxide and harmful substances using the cassettes attached to the unit with the appropriate types of absorbers.

Compressed oxygen from the cylinder 3 through the oxygen supply shield 4 enters the oxygen supply control console 8 to the pressure chamber 7, while on the console, before being fed into the balloon, it is reduced to a pressure of 1.0 MPa. After that, the oxygen enters the devices (masks) of individual breathing with oxygen 9 and further to the breathing of divers, and on the exhale through the hose to discharge outside the pressure chamber.

If necessary, increase the oxygen content in the gas atmosphere of the pressure chamber 7 compressed oxygen from the cylinder 3 through the shield supplying oxygen 4 enters the supply console 8 and the oxygen metering device 10, and then into the pressure chamber 7.

To ensure the diving descents and the functioning of the pressure chamber, the complex has a supply of compressed air in six cylinders 12 with a working pressure of 20.0 MPa and a capacity of 80 liters each. The compressed air from the cylinders 12 enters the control panel of the compressed air supply 13 into the pressure chamber to create pressure in it, on this control panel, before being fed into the pressure chamber, the compressed air is reduced to a pressure of 3.0 MPa, and this control also serves to release pressure from the pressure chamber to atmosphere during decompression. When replenishing the stock of compressed air in cylinders 12 of the mobile complex, air is supplied from an external source. The supplied compressed air before being pumped into the cylinders 12 is preliminarily cleaned of harmful impurities to the existing standards, for which a filter 22 of the type FVD-200U can be installed in the complex.

To create a comfortable stay (temperature and humidity) in the container 1, an air conditioner 14 is installed, and to ensure the safe descent of divers into the water, a folding ladder 15 is installed.

To ensure fire safety, the mobile complex is equipped with:

fire alarm 19 for temperature control;

instruments for monitoring the volume content of oxygen 20 in rooms 16 and 17 of container 1;

equipment exhaust ventilation 18 to reduce the volumetric oxygen content in the premises of the container;

the system of supplying outboard water for cooling all the cylinders 21 in case of fire, which is included in the work after the signal from the fire alarm system 19.

The described mobile complex was manufactured and tested in the design and manufacture of a mobile container diving complex (ICWC). In terms of its technical parameters, it allows the functionality of a mobile complex adopted as a prototype to be expanded through the use of oxygen equipment, the possibility of preparing oxygen-nitrogen gas mixtures and the use of structures and equipment of the complex made of low-magnetic materials. The safety of its operation is increased by ensuring the fire safety of oxygen equipment (its location in a dedicated room). In addition, the placement of individual respiratory devices (masks) in the pressure chamber improves the quality of therapeutic recompression and the safety of decompression of divers in the pressure chamber.

To ensure special works on demining the water area, hull structures and equipment of the mobile diving equipment complex can be made of low-magnetic materials, which will also expand the functionality of the proposed mobile complex.
