The invention relates to the field of underwater technology, and more particularly to submersible unmanned self-propelled or towed vehicles.

To provide research and practical work on the development and utilization of mineral resources of the World ocean created the whole direction of the rapidly developing underwater technology, composed and self-propelled underwater uninhabited vehicles and towed surface ship underwater vehicles. The subs are carriers of a wide variety of electronic equipment, sonar equipment, sensors and measuring devices, many of which must be in position at the required distance from the body of the device, which requires their locations on the special panels and the pylons, which are usually rigidly attached to the hull of the submersible. However, speakers panels, as well as necessary to stabilize the movement of the apparatus in the water hydrodynamic vertical and horizontal wings, stabilizers provide the technical and operational problems during deployment and retrieval of the underwater vehicle and require a cumbersome and complicated trip podemnik devices on surface ship carrier even for small underwater vehicle. To avoid this drawback in the construction of the underwater apparatus is of ATA, as well as in the aerospace and rocket technology, which suffers from similar disadvantages, use the idea of a retractable device panels, which involves automatic way of niš corps on a given plot movement or timing program, or reach any other criterion parameter. With the use of different principles of construction of the device of the extension panels and stabilizer apparatus (for example device according to U.S. patent No. 4,323,208 from 04.1982,; 4,334,657 from 06.1982,; 4,471,923 from 09.1984 year). Closest to the proposed invention is a device for U.S. patent No. 5,602,801 from 11.02. 1997 hydroacoustic system for self-propelled underwater vehicle containing a movable panel with acoustic sensors. Panels can be folded or unfolded position perpendicular to the axis of the submersible. The design principle of the device extension in the invention is not declared in the form of analog reference is made to US Patent 4,667,899 from 26.05.1987, samostanowienia double wing variable sweep.

Samostanowienia the structure of the wing to improve the characteristics of the missile and its maneuverability without significantly reducing the useful volume includes rotary wing attached to the apparatus body in vtyanuta the state in which the wing wrase is camping around "located at wingspan" axis relative to the open position, and turn forward next to the body of the rocket. The rotatable components allow air flow to rotate the wing in the open position when it is released from venutolo status during flight. This device uses the energy of air flow. The environment for underwater vehicle is water, and in addition, due to specific characteristics of an air missiles, this device does not solve the problem, reusable rockets with automatic reverse folding of the wings (panels) in the environment after completion of its work.

The present invention is the development of automatic sliding and folding sliding panels moving underwater vehicle that provides small size and compactness of its design as in the transport position and in the process of setting and sampling underwater vehicle, due to the presence automatically extendable and collapsible panels.

This task is ensured by the fact that the automatic sliding and folding retractable horizontal and vertical panels moving underwater vehicle includes a power mechanism that provides two-way force on the sliding mechanism driving the connected panel fixed axes to the body apt the rata with the possibility of rotation of the panels around their axes, and the slide mechanism includes a Central tube axis can be moved along the axis of the two levers, each of which is hinged to one side of the Central tube and the other side with the inner surface of one of the horizontal panels, and can move along an axis fixed to the Central tube of the vertical bracket stops constantly in contact with the ends of the vertical panels and creates a torque reversal vertical panels around their axes to bring them in vertical position.

The lift mechanism may be made in the form of electric drive with worm and screw on the axis of the worm Central tube with the opportunity during the operation of the drive movement of the Central tube in the direction of sliding panels, reverse movement of the Central tube in the direction of folding of the panels when the drive is running in reverse mode, and also includes a control system consisting of a software device, a speed sensor of the apparatus, the limit switches of the actuator and the power source.

Power mechanism for automatic sliding and folding sliding panels moving underwater vehicle made in the form of a hydrodynamic drive connected to the Central tube and return C lindrical spring, mounted on the Central tube. This hydrodynamic drive is interoperable with a forced flow of water and facilitates the movement of the Central tube along its axis and the actuation of a sliding mechanism when the speed of the towed underwater vehicle, in which the action of the incoming water pressure in the hydrodynamic drive overcomes the resistance of the return spring and return spring is installed with the possibility of a reverse automatic folding back the panels at the speed of towing, in which incoming water pressure does not provide power to overcome the forces bogatoi recoil.

To implement the device features a design in which the power mechanism is in the form of a hydrodynamic drive sleeve and the cylindrical return spring mounted on the sleeve, having the opportunity to provide under the action of the incoming water pressure in the hydrodynamic drive at speeds towing underwater vehicle, when the action of the incoming water pressure in the hydrodynamic drive overcomes the resistance of the return spring, the movement of the sleeve along the axis of the power mechanism and to actuate the slide mechanism, representing the Executive device. The first device consists of dvuhruchevoj, United hinge connections with the sleeve of the power mechanism and the inner surfaces of the horizontal panels, with the possibility during movement of the sleeve and spatial movement of the levers to provide a force on the horizontal bar and to deploy the latest around the axes of rotation of the panels to bring them in horizontal position and contact with the rest of the submersible. Second - in the form attached to the sleeve of the power mechanism of the vertical bracket with lugs in contact with the ends folded in a horizontal position vertical panels, with the possibility during movement of the sleeve providing a force action on the ends of the vertical panels and expand the latter around the axis of rotation of the panels to bring them in vertical position and contact with the rest of the submersible. The return spring is installed with the possibility of a reverse automatic folding back the panels at speeds towing underwater vehicle, when the incoming water pressure is not providing power to overcome the forces bogatoi recoil.

Figure 1 illustrates the proposed design of automatic sliding and folding sliding panels, which is located on axis 1, is installed in the sleeve 2 with the bracket 3, is rigidly fixed on the center on the bottom of the hull underwater vehicle 4. The device consists of a Central pipe and 5, to the front end of which is attached a removable hydrodynamic disk 6 by bolts 7, and the rear end is attached to the threaded connecting sleeve 8. With this Central tube 5 with hydrodynamic drive 6 have a Central through hole, providing freedom of movement along the axis 1. In the first actuators retractable mechanism includes a sleeve 8 having two brackets 9, which are located at a certain angle in the upper half-plane, on which are mounted the brackets 10, which provides swivel levers 11, secured its other end a similar hinge connections with horizontal panels 12 (in particular the constructions are horizontal hydrodynamic stabilizers underwater vehicle). The second execution unit sliding mechanism is attached to the sleeve 13 vertical bracket 14 with the lugs 15 in contact with the ends folded in a horizontal position vertical panels 16. The sleeve 13 is freely mounted on the Central tube 5 with the possibility of free movement along it. At the same time, the inner side of the sleeve 13 has a latch 17, which is a longitudinal slot 18 of the Central tube 5, which determines the stroke of the latch 17. On the Central tube 5 planted suratna spring 19 and the spring 20. Return spring 19 one end of which rests in the hydrodynamic drive 6 and the other at point blank range 21 rigidly mounted on the housing of the underwater apparatus 4 and provides for the free passage of the Central tube 5 inside it. The stop 21 is separated from bogatogo hydrodynamic disk 6 at a distance, providing a working stroke return spring 19. Spring 20 one end of which rests in the sleeve 13 with a vertical bracket 14, and the other at point blank range 22 rigidly mounted on the Central tube 5. The stop 22 is separated from the sleeve 13 at a distance that ensures the progress of the latch 17 in the longitudinal slots 18 and working stroke of the spring 20. Fastening device for automatic separation of axis 1 and the panels 12 and 16 on the submersible must provide their correct relative position.

Figure 2 shows a detailed construction of the automatic sliding and folding vertical panels. Point of contacts "To" emphasises vertical bracket 14 with the ends folded in a horizontal position vertical panels 16 must be distant from the axis of rotation 23 of the panels 16 at distances L₁"equal distance "L₂" the ends of the panels 16 from the axis of rotation 23. While the torsion spring 24, one end attached to the hooks 25 of the panels 16 and the other on the housing of the underwater apparatus 4, in an unstressed condition ensures retention Vert is unique panels 16 in the folded position, and when they are forced disclosure provide torque, requiring the return of the panels in the folded state.

Figure 3 displays the horizontal bar 12 attached to the housing of the underwater vehicle 4 on two swivel connection 26 with the axes 27 and the torsion spring 28, the principle of which is similar to the previously described vertical panels 16.

Figure 4 shows the location of the device in the composition of the underwater vehicle 4 with folded 12 horizontal and 16 vertical panels. The position of the panels is provided in the transport position of the underwater vehicle 4, and during its production, sampling and towing at speeds towing V_B≤V_Pwhere V_P- threshold speed towing underwater vehicle 4. The pressure flow in the hydrodynamic disk 6 does not provide sufficient force to overcome the force bogatoi return spring 19. Hydrodynamic drive 6 with the Central tube 5 and, respectively, the power and pull-out mechanisms are at rest.

Figure 5 shows the device in the composition of the underwater vehicle 4 in the working position apart horizontal 12 and 16 vertical panels. The position of the panels is ensured when towing underwater vehicle 4, when the pressure of the incoming flow on the Hydra is a dynamic disk 6 provides the force sufficient to overcome the force bogatoi return spring 19, and a hydrodynamic drive 6 with the Central tube 5 is moved to a distance of H₁to another dynamic disk 6 in the end a fully compressed return spring 19. The distance H₁moves and sleeve 8, which provides a spatial movement of the levers 11, which exert a force on the horizontal bar 12, overcoming the efforts of the preload of the torsion spring 28 and turning the plate around the axis of rotation 27 to bring the panels in a horizontal position and contact with the rest of the underwater apparatus 4. Simultaneously with the movement of the Central tube 5 with the stop 22 is a compression spring 20 and the movement of the latch 17 of the sleeve 13 in the longitudinal slot 18 of the Central tube 5. The length of the slot 18 compensates for the difference (H₁-H₂in working movement of the sleeve 8 (H₁and sleeve 13 (H₂)needed to bring the panels 16 in a vertical position. After bringing the latch 17 in the extreme right position of the slot 18, the force of movement of the Central tube 5 through the point of contact "To" lugs 15 of the vertical bracket 14 is transmitted to the ends folded in a horizontal position vertical panels 16, overcoming the efforts of the preload of the torsion spring 24 vertical panels 16. The lugs 15 are deploying vertical the main panel 16 around axis 23, bringing and holding them in a vertical position due to the contact planes of the lugs 14 and the ends of the panels 16. By reducing the speed of the towed underwater vehicle 4 to those values when the force of the return spring 19 together with the torsion springs 24 and 28 all panels overcome the force of the pressure flow in the hydrodynamic drive 6 and bring him and, respectively, the power and pull-out mechanisms of the device to its original state of rest. Thus, automatic folding retractable panels moving underwater vehicle 4.

6 illustrates the construction of an automatic sliding and folding sliding panels, in which the pulling device can be used in the drive. Thus instead of axis 1 in the sleeve 2 is mounted on the bearings of the worm 30, which is screwed on the Central tube 31. The front end of the worm 30 is connected to the shaft of the actuator 32. On the outer surface of the tube 31 is rigidly fixed to the latch 33, which can make free longitudinal movement along the guide 34 attached to the lower housing 29 underwater vehicle 4. When the actuator 32 of the rotational movement of the worm 30 is converted into a longitudinal movement along the axis of the device Central tube 31, which established the modern sleeve 8 and 13 actuators retractable mechanism, construction and operation of which are described above. The operation of the power device is controlled according to commands of the control system, consisting of software switching device 35, a speed sensor 36, the movement of the device, limit switches 37 of the actuator 32 and the power source 38.

Thus, as in the transport position of the underwater vehicle 4, and during its production, sampling and towing at speeds towing V_B≤V_Pthe Central tube 31 is in its rightmost position and the underwater vehicle 4 is towed with folded 12 horizontal and 16 vertical panels.

When reaching the speed of towing V_B>V_Pfrom the speed sensor 36 signals using software switching device 35 to actuate the actuator 32, which provides movement of the Central tube 31 and, accordingly, actuators retractable mechanism, thereby opening 12 horizontal and 16 vertical panels underwater vehicle 4. Upon reaching the Central tube 31 of the leftmost position of the latch 33 abuts against the end deactivation switch 37 and the actuator 32 terminates.

After work underwater vehicle 4 and the speed reduction towing to the value of V_B≤V_Pfrom the speed sensor 36 is fed the signal through PR is gramme-switching device 35 on the reverse actuation of the actuator 32, which provides backward movement of the Central tube 31 and, accordingly, actuators retractable mechanism than is achieved by folding 12 horizontal and 16 vertical panels underwater vehicle 4. Upon reaching the Central tube 31 rightmost position, the latch 33 reaches the second limit deactivation switch 37 and the actuator 32 terminates.

The automatic sliding and folding retractable horizontal 12 and 16 vertical panels moving underwater vehicle 4 operates as follows. When the underwater vehicle 4 in the transport position, with his deployment and retrieval on a surface ship and towing at speeds when the pressure flow in the hydrodynamic disk 6 does not provide sufficient force to overcome the force bogatoi return spring 19, 12 horizontal and vertical panel 16 underwater vehicle 4 are in the folded position. When the underwater vehicle 4 in working condition in the speed range, when the pressure of the flow in the hydrodynamic drive 6 provides sufficient force to overcome the force bogatoi return spring 19, and a hydrodynamic drive 6 with the Central tube 5 is moved to another dynamic disk 6 in the end completely samovozgoranii spring 19. At the same time moves the sleeve 8, which provides a spatial movement of the levers 11, which exert a force on the horizontal bar 12, overcome the efforts of the preload of the torsion spring 28 and deploy the horizontal bar 12 around the axis of rotation 27 to bring them in horizontal position and contact with the rest of the underwater apparatus 4. Simultaneously with the movement of the Central tube 5 with the stop 22 is a compression spring 20 and the movement of the latch 17 of the sleeve 13 in the longitudinal slot 18 of the Central tube 5. After bringing the latch 17 in the extreme right position of the slot 18, the force of movement of the Central tube 5 through the lugs 15 of the bracket 14 is transmitted to the ends folded in a horizontal position vertical panels 16 and overcomes the efforts of the preload of the torsion spring 24 vertical panels 16, turning them around axis 23, leading and holding them in a vertical position due to the contact planes of the lugs 15 and the ends of the panels 16. Underwater vehicle 4 in the working position is apart horizontal 12 and 16 vertical panels. By reducing the speed of the towed underwater apparatus to, when the force of the return spring 19 together with the torsion spring all panels overcome the force of the pressure flow in the hydrodynamic drive 6, provide p is evidenee disk 6 and accordingly, the power and pull-out mechanisms of the device to its original state of rest. Thus, automatic folding retractable panels moving underwater vehicle 4.
