The invention relates to rescue crews, emergency submarines (PL) in a submerged position with the use of rescue underwater vehicle (SPA).

Known connecting device (French patent No. 2264713, the IPC 63 G 6/40, publ. 17.10.75), performed in the camera view landing and suction with a support flange and seal.

A disadvantage of the known connecting devices is the limited performance, because it can be combined only with horizontal coaming area of the underwater object.

The known device provides means for coupling camera landing and suction, providing for the positioning of the camera in the horizontal plane near the coaming-site emergency underwater object only if its horizontal bedding, which significantly limits the possibility of mating with emergency underwater object.

There are other docking device that allows you to dock underwater vehicle (PA), for example, diving, ship's deck decompression complexes “...top, side, and sometimes from below...” (Ghauts. Underwater engineering. Leningrad: Sudostroenie, 1972, s.255, 256). However, such connecting devices cannot be reoriented to fit on the object having a different angle of the receiver, especially if this angle is not zwesten in advance.

A device for docking SPA with underwater object, mainly, with emergency PL camera including planting and suction with a support flange and a seal housing which includes an upper belt, rigidly connected with the stationary element, the intermediate and the lower belt made with the possibility of rotation of the belt by using the rotation mechanism placed inside the chamber, which is connected between a flange connectors with garter clips, and the intermediate belt is made so that the bottom plane of its connector is with the top plane of its connector angle not less half of the maximum angle of inclination of the coaming-site underwater object there are plans to plant (patent RF №2157776, the IPC 63 G 8/40, publ. 20.10.2000).

A disadvantage of the known connecting devices SPA is the deterioration of the conditions of the rescue operations, the difficulty of the passage of personnel through the camera landing and suction due to the placement of the rotation mechanism of the intermediate and lower zones, made in the form of two gears that control the rotation of each of the belts on the inside of the chamber and reduce the useful volume of the latter, and in the absence of the elements of the clamping-disconnection of connectors flanges swivel ball segments camera body boarding and suction needed to obespecheniya integrity by eliminating gaps in the sealing, and the ease of spread of the flanges at the expense of creating these gaps. In addition, the presence of holes for the passage of the swivel mechanisms through the “wall” belts cameras planting and suction is also a disadvantage because it reduces the reliability of both device and PA in General.

The known device for docking SPA with underwater object, mainly, emergency DPS, including fixed base camera landing and suction with a support flange and the seal of the upper, intermediate and lower zones associated with each other by means of flanges with garter clips and a rotation mechanism of the intermediate and lower zones, made in the form of two gears, while the upper zone is rigidly connected to the fixed base, and the intermediate belt is made so that the bottom plane of its connector forms with the top plane of its connector angle not less half of the maximum angle of inclination of the coaming-site underwater object selected as the closest analogue of the claimed invention.

The known device provides means for coupling SPA with underwater object, mainly, emergency DPS, using the device for docking into the camera view of the landing and sucker made of spherical zones (segments), movable relative to each other /patent RF №2157776, MP is 63 G 8/40, publ. 21.10.2000/. The method includes positioning an underwater vehicle over an underwater object, the rotary movement of ball segments camera body boarding and suction by turning consistently lower, and then the intermediate spherical zones with the possibility of parallel placement of the planes of the mating flange cameras planting and suction and coaming-site underwater object, the accession of the mentioned cameras SPA to coaming-site emergency DPS, with the formation of the transition chamber and the draining of the transition zone. There is a method of dock allows you to carry out the emergency works at an inclined position coaming-site emergency DPS, but it is characterized by the duration and difficulty of the work due to the absence of the possibility of closing-opening of the connector flanges swivel ball segments camera body boarding and suction to ensure their integrity, and the relative ease of spread, as well as reduced bandwidth of the transition chamber.

The known method of joining SPA with underwater object, mainly, emergency DPS, using the device for docking camera including planting and suction body with the moving belts, which provides for the positioning of the rescue submersible over underwater object to supply the second position, move the swivel ball segments camera body boarding and suction by turning consistently lower, and then the intermediate spherical zones with the possibility of parallel placement of the planes of the mating flange cameras planting and suction and coaming-site underwater object, the subsequent addition of the above-mentioned camera to coaming-the site of an underwater object with the formation of the transition zone and the drainage of the transition zone, is selected as the closest analogue of the claimed device.

The objective of the invention is to improve the operational characteristics of the SPA, as well as improving the efficiency of the rescue crews with emergency DPS, reliability and high speed connections and help in distress.

The problem is solved by the fact that in the known device for docking rescue underwater vehicle with an underwater object, mainly, emergency submarine, including fixed base camera landing and suction with a support flange and the seal of the upper, intermediate and lower zones connected by connectors through the flanges with garter clips, as well as the mechanism of rotation of the intermediate and lower zones, the upper zone is rigidly connected to the fixed base, and the intermediate belt is made such that the lower is locost its connector forms with the top plane of its angle connector, not lower half of the maximum angle of inclination of the coaming-site underwater object, in accordance with the invention, the said rotation mechanism intermediate and lower zones is installed outside zones and made in the form of epicycle gear, containing the Central toothed wheel mounted on a fixed base or on the top belt for rotation about a vertical axis of the upper connector of the intermediate belt, a sun gear rigidly connected with the lower belt, the axis of which is aligned with the inclined axis of the lower connector of the intermediate belt, and connected with a flexible coupling of the planetary gear, pivotally mounted on the intermediate belt securing engagement with the said Central and the sun gears and the Central gear wheel is connected with the source of movement, rigidly connected to the fixed base, and tightening clip connectors flanges of belts fitted with an individual hydraulic clamping-disconnection of connector flanges.

In addition, the solar wheel is mounted at an angle to the vertical axis of the intermediate chamber, not lower half of the maximum angle of inclination of the coaming-site underwater object, which is provided by the landing.

In addition, as a fixed base selected case SPASATEL the aqueous underwater vehicle.

The problem is solved also by the fact that in the known method of joining rescue underwater vehicle with an underwater object, mainly emergency submarine, using the device for docking camera including planting and suction body with movable belts, providing a positioning and rescue underwater vehicle over an underwater object in a submerged position, the rotation of the lower and intermediate spherical zones with the possibility of parallel placement of the planes of the mating flange of the mentioned cameras and coaming-site underwater object, the subsequent addition of the above-mentioned camera to coaming-the site of an underwater object with the formation of the transition zone and the drainage of the transition zone, in accordance with the invention, when the positioning rescue submersible provide the possibility of relative movement of the lower belt mentioned the camera, turn the lower zone of the mentioned cameras to ensure the equality of the angles of inclination of the plane of the support flange of the said belt and coaming-site emergency underwater object to the horizontal plane, then match the intermediate and lower zones of the mentioned cameras and allow their joint movement relative to the upper belt and parallel to the plane of the mating flange and omings-site provide by turning the paired intermediate and lower zones referred to the camera about its vertical axis, then match the intermediate and upper zones of the mentioned cameras.

The technical result of the invention is to increase the useful volume of the chamber planting and suction without increasing its size by placing the rotary mechanisms outside of the camera (outboard motor), with the exception of the holes in the chamber walls for the passage of the swivel mechanisms, ensuring speed and tightness of coupling SPA with alarm object in a submerged position.

The invention is illustrated by figure 1, which presents a General view of the camera landing and suction, and figure 2, which presents the same camera in a ready position for docking with the coaming area lying at an angle to the vertical axis of the camera.

With the lower belt 4 cameras planting and suction rigidly connected to the mounting flange 9, which provides landing camera on the emergency object. The upper surface of the connector 5 of the intermediate zone 3 horizontal and its lower plane of the connector 6 is located at an angle not smaller floors shall have a maximum slope angle coaming-platform object, on the scheduled landing. The flanges of the zones 2, 3, 4 cameras planting and suction is supplied with seals 10, 11 and 12. The upper belt 2 and the intermediate zone 3 coaxial, vertical axis 13 is the axis and the upper connector and the rotation of the intermediate belt 3, and the rotation of the lower belt 4 is inclined around the axis 14 of the lower connector intermediate zone 3, perpendicular to the plane of the flange connector 6 between the intermediate 3 and the bottom 4 zones. The rotation of the intermediate 3 and the bottom 4 of the zones is carried out by means of the rotary mechanism, is placed outside of the camera landing and suction in the form epicycle (including links committing rotation about a movable axis) transmission.

The rotary mechanism includes a Central gear wheel 15 mounted on the housing 1 or on the upper belt 2 with a possibility of rotation about the axis 13, the planetary gears 16 and 17, pivotally connected with the intermediate zone 3 and connected with a flexible coupling 18 (articulated coupling), and includes a sun gear 19 rigidly connected with the lower belt 4, and the axis of the sun gear 19 is aligned with the axis 14. Pairs of gear wheels 15 and 16, 17 and 19 are in constant engagement. The Central gear wheel 15 is connected with the motor 20, which is the source of movement, through the tooth to the ECA 21, 22, 23 and coupling 24. The hydraulic motor 20 is rigidly connected with the main body 1 SPA. Pairs of gear wheels 15 and 21, 22 and 23 are in constant engagement, and the wheels 21 and 22 are rigidly connected to each other. Each of the tightening of the clamps 7 and 8 are connected with the hydraulic motors 25 and 26 respectively engaged in circuit - opening flanged connectors 5 and 6 of their belts. The hydraulic motors 25 are rigidly connected either with the upper belt 2, or housing 1 SPA. The hydraulic motors 26 are rigidly connected with the intermediate belt 3 and is equipped with a movable element 27 for supplying a working fluid.

The device contains the valves 28, 29 with the average position 30, 31 piping from discharge. Positions 32, 33 of the distributor 28 respectively correspond to the mode of the pressure for the hydraulic motors 25, 26. Positions 34, 35 of the distributor 29 answer mode “pressure” to rotate in the opposite side of the motor 20. Hose 36, 37, 38, the valves 28, 29 are connected with a pressure source (not shown), and the hose 39, 40, 41 are connected with the drain tank 42. The valve 28 hose 43, 44, 45 associated with the hydraulic motors 25 and hose 46, 27, 47, 48, 49 associated with the hydraulic motors 26. The valve 29 hose 50, 51 associated with the motor 20, which drain hydroline 52 is connected to the tank 42. In the initial position, the hydraulic motor 20 and the hydraulic motors 25, 26 soy is inany with the drain tank 42 through positions 31, 30 valves 29, 28, respectively hose 50, 51, 40, 41, 44, 45, 43, 39, 41 and 48, 49, 47, 27, 46, 39, 41.

Docking SPA with emergency underwater object in a submerged position is as follows. In the initial position the camera landing and suction SPA installed in position “travelling”, as shown in figure 1.

SPA moves, managed with its own propulsion and steering unit, is released in the disaster area, the underwater object and taking possible or convenient for planting (depending on the underwater environment) position, hangs over the coaming area of the emergency object (a special case of positioning SPA active or passive management process local linear and angular displacements of the SPA in the water space at low speeds its translational movements).

Connectivity is determined by the maximum angle of inclination of the coaming-site emergency underwater object (not more than 60 degrees relative to the horizontal plane), and considered, as a rule, already when designing the intermediate and lower zones of the cameras of planting and suction SPA by setting the bevel angle of one of the joints flanged connector forming her belt.

SPA held in a predetermined position in space without progress. Using system hydraulic control ensures p is syedinenie connector flanges 6 of the bottom 4 and the intermediate 3 zones cameras planting and suction, providing relative movement of these belts, and then using the rotary mechanism deploy lower belt 4 cameras planting and suction so that the angle of the support flange 9 has become equal to the desired angle coaming-site emergency underwater object relative to a horizontal plane. After this match intermediate 3 and the bottom 4 of the belt connector 6 flanges and provide separation of the connector 5 intermediate flanges 3 and top 2 zones cameras planting and suction, and then deploy the intermediate zone 3 together with the lower belt 4 so that the mounting flange 9 position, parallel coaming-site, as shown in figure 2, and then match the intermediate 3 and the top 2 belt connector flanges 5.

In this work mechanisms and hydraulic actuator is controlled as follows. For reversal of the lower belt 4 cameras planting and suction valve 28 is installed in position 33, while the working fluid under working pressure for hose 36, 37, 46, 27, 47, 48, 49 through position 33 is supplied to the hydraulic motors 26, and the hydraulic motors 25 to the hose 44, 45, 43, 39 and 41 through position 33 is connected with the drain tank 42. The hydraulic motors 26 open spring-loaded tightening clamps 8 and unlock the flange connector 6. This garter spring clip 7 stauts is closed, and flanged connector 5 is normally closed. Then the valve 29 is installed in the appropriate position 35 (or 34) and the working fluid under working pressure of the hose 36, 38, 51 (36, 38, 50) through the position of the 35 (or 34) is fed to the hydraulic motor 20 and the hose 50, 40, 41 through the position 35 (or hose 51, 40, 41 through the position 34) flows into the drain tank 42. The hydraulic motor 20 carries out the rotation in the appropriate direction and transmits torque through the clutch 24 toothed wheel 23 through which rotation is transmitted rigidly interconnected gear wheels 21 and 22 and further the Central toothed wheel 15, the transmitting rotation of the planetary gear wheel 16. Then through the hinge coupling 18, the rotation is transmitted to the planetary gear wheel 17, which causes the rotation of the sun gear 19 mounted at an angle to the vertical axis of the intermediate chamber, not lower half of the maximum angle of inclination of the coaming-site underwater object, which is provided by the landing. The sun gear 19 due to the rigid connection with the lower belt 4 expands its axis 14 at a desired angle, so that the plane of the support flange 9 is rotated in space to the desired angle relative to the horizontal plane. Then the valve 29 is installed in position 31 connection with the discharge of the motor 20 through the hydroline 50, 51, 40, 41 to stop the spread of the lower belt 4.

To turn the intermediate zone 3 together with the lower belt 4, the valve 28 is installed in position 32 and the working fluid under working pressure of the hose 36, 37 43, 44, 45 through the position 32 is supplied to the hydraulic motors 25 and the hydraulic motors 26 for hose 48, 49, 47, 27, 46, 39, 41 through position 32 are connected with the drain tank 42. Occurs simultaneous actuation of the hydraulic motors 25 and 26. The hydraulic motors 25 open spring-loaded tightening clamps 7 and unlock the flanged connector 5. Simultaneously, the garter spring clips 8 are closed due to the connection with the discharge of the hydraulic motors 26, flange connector 6 is normally closed. Then the valve 29 is installed in the appropriate position 34 (or 35) and the working fluid under working pressure of the hose 36, 38, 50 (36, 38, 51) through the position 34 (or 35) is fed to the hydraulic motor 20 and the hose 51, 40, 41 through the position 34 (or hose 50, 40, 41 through the position 35) flows into the drain tank 42. The hydraulic motor 20 starts to rotate in the appropriate direction, transmitting torque through the clutch 24 toothed wheel 23 through which rotation is transmitted rigidly interconnected gear wheels 21 and 22 and further the Central toothed wheel 15. Since the flange connector 6 normally closed and intermediate p the Yas 3 is rigidly connected with the lower belt 4, which is rigidly connected a sun wheel 19, which is in constant mesh with the toothed wheel 17 and interconnected by a coupling 18 of the planetary gears 16, 17 are pivotally connected with the intermediate zone 3, the rotation of the gear wheels 16, 17 relative to the intermediate zone is excluded, this shall also be eliminated and the rotation gear wheel 16 relative to the Central gear wheel 15. The Central gear wheel 15 and the planetary gear 16 are in constant engagement. Thus, during the rotation of the Central gear 15 synchronously with him takes place in the desired position relative to the axis 13 are rigidly interconnected intermediate 3 and the bottom 4 belt camera landing and suction, while with them relative to the same axis 13 unfolding planetary gears 16, 17 and sleeve 18. Then the valve 29 is installed in position 31 connection with the discharge of the motor 20 through the hydroline 50, 51, 40, 41 to stop the spread of interconnected intermediate 3 and the bottom 4 zones, after which the valve 28 is installed in position 30 connection with the discharge of the hydraulic motors 25, 26 to ensure proper closure flange connector 5, and continue with normal closure flange connector 6. The mounting flange 9 of the camera landing and suction SPA is state is parallel to the coaming-site emergency PL.

After this SPA, working vertical propulsion complex, falls on coaming-the site of the underwater object and pressed against her anchor flange 9. Once the mounting flange 9 will be pressed against the coaming-the site of an underwater object, the camera landing and suction sharply reduce the pressure by discharge of water in the inner tank SPA. There is a “sucker” SPA to an underwater object.

The sealing rings 10 and 11 provide a seal in the normally closed flange connectors 5, 6, and the seal ring 12 is between the support flange 9 camera landing and suction SPA and coaming-site emergency underwater object.

Under the effect of external hydrostatic pressure SPA through the camera landing and suction (stationary upper belt 2 and the movable intermediate 3 and the bottom 4 of the belt) is pressed against the coaming-the site of the underwater object, providing the rigidity and tightness of contact that allows after pumping water from the transition zone camera landing and suction inside the containers, placed in a SPA, to open the sun roof system, sun roof emergency underwater object and to accept or transfer of people and cargo.

Undocking SPA from the underwater object and bringing the device to its original position is in the reverse order.

Known simple epicycle gear, made in the form of differential before the Chi, which includes links committing rotation about a movable axis (satellite), with one leash-led (Snegirev, AIESEC, Jamesin. Elements of mechanisms. M: Barongis, 1956, s-206, Fig). The movement of the links of such a mechanism will be determined if you will set the rotation of any two parts of the transmission. In the particular case of one link can be fixed, resulting in still leash-the driver can get a simple transfer, and in case of stop of the Central wheel of the planetary gear. However, the known design of the differential transmission can not be used for rotary mechanisms mobile belts cameras planting and suction SPA due to the inability to deploy each of the mobile belts separately.

The invention improves the operating characteristics of the SPA by increasing the useful volume of the chamber planting and suction without increasing its size, ease of passage of personnel through this chamber, the improvement of the conditions of the rescue operations in extreme situations, as well as through operational support as full tightness of connectors flanges swivel belt camera landing and suction and ease of their relative movement. It also increases the reliability of the design both device and SPA in Elam due to the exclusion of holes for the passage of the swivel mechanisms through the “wall” in the zone chambers landing and sucker. In addition, improving the efficiency of the rescue crews with emergency PL, increases high speed connections and help in distress.
