Background
At present, the design of the stabilizer of a large deep sea manned vehicle generally takes the resistance performance, stability and maneuverability for high-speed sailing, the size limit requirement for port entry and exit and the possibility of winding collision under complex working conditions as main design bases, the projected area of the stabilizer is relatively small, and the design does not exceed the size of a main body or slightly exceeds the size of the main body as far as possible, and the design has the following typical problems: the design of the small projection area stabilizing wing leads to insufficient current-resisting capability of the submersible during low-speed navigation and the danger of uncontrollable flow-by-flow along with waves when large ocean currents are encountered. For the transverse ocean current with the same flow speed, the resultant speed inflow angle formed when the submersible is sailed at the low sailing speed is larger, and the resultant speed inflow angle formed when the submersible is sailed at the high sailing speed is smaller. A larger deflection angle will result in a larger disturbance force, which can only be resisted by a larger configuration of the tail stabilizer area. However, the design of the stable span length is limited, and the effect of increasing the span length is not obvious, so that the problem of weak current-resisting capability of the submersible in low-speed sailing is brought. When the submersible adopts larger extension to form larger stable wing area, the maneuverability of the submersible is seriously weakened, the operation capability is influenced, and the sailing resistance is increased.

The invention can adjust the requirements of the large deep sea manned carrier on the performance thereof under different sailing conditions, has higher requirements on the resistance performance and the carrier maneuverability during high-speed sailing, and is in a contraction state as shown in figures 2 and 3, namely the top ends of the first-stage telescopic wing 3 and the second-stage telescopic wing 4 are flush with the top end of the fixed wing 2. The specific implementation when the vehicle is turned from high speed to low speed is as follows:
in the environment with ocean currents, when a large deep sea manned carrier is changed from a high-speed sailing state to a low-speed sailing state, an included angle between the sailing direction of the carrier and the flow direction of ocean currents and the ocean current speed can be measured through flow direction and flow speed sensors carried by the carrier, the requirement for the stability of the carrier is calculated through the sailing speed of the carrier, and the required area of a stable wing is calculated according to the requirement. Then, under the hydraulic action and control, the primary rod 8 extends out of the hydraulic cylinder 7 and drives the horizontal base 802 to move together, the horizontal base 802 pushes the two small lug plates 801 to move, the two small lug plates 801 push the perforated sealing plate 301 to move, and the perforated sealing plate 301 pushes the primary telescopic wing 3 to extend out of the fixed wing 2, so that the area of the stabilizing wing is increased. Before the primary telescopic wing 3 does not reach the telescopic stroke, the secondary rod 9 moves synchronously with the primary rod 8, namely the two rods are relatively static. At this time, the second-stage rod 9 drives the big ear plate 901 to move together when moving, and pushes the second-stage telescopic wing 4 and the first-stage telescopic wing 3 to move synchronously in the same direction. In the process of extending the first-stage telescopic wing 3, the extending distance of the first-stage telescopic wing 3 relative to the fixed wing 2 is measured by the first-stage distance measuring device 5 at any moment, and the transverse projection sectional area of the stabilizing wing is fed back to the carrier to calculate whether the transverse projection sectional area meets the stability requirement, and if the low-speed navigation stability requirement of the carrier is met, the hydraulic pressure is controlled to stop the telescopic wing to continue extending.
If the wing area of the first-stage telescopic wing 3 still cannot meet the stability requirement of low-speed navigation of the large deep-sea manned carrier after reaching the extension stroke as shown in fig. 6, the extension function of the second-stage telescopic wing 4 is started, and the wing area is further increased as shown in the figure. Because the first-level telescopic wing 3 reaches the extension stroke, the first-level rod 8, the horizontal base 802, the two small ear plates 801, the perforated sealing plate 301 and the first-level telescopic wing 3 are all in a static state, as shown in fig. 6, at this time, under the hydraulic control, the second-level rod 9 starts to move to extend out the first-level rod 8 and drive the big ear plate 901 to move, the big ear plate 901 pushes the second-level telescopic wing 4 to extend out the wing hole of the first-level telescopic wing 3, the whole area of the stabilizing wing continues to be increased, as shown in fig. 7, until the requirement of navigation stability is met. In the process of extending the secondary telescopic wing 4, the sliding-out distance of the secondary telescopic wing 4 relative to the primary telescopic wing 3 is measured by the secondary distance measuring device 6 at any moment, and whether the increase of the transverse projection sectional area of the carrier meets the stability requirement is calculated.
When the carrier changes from low-speed navigation to high-speed navigation, the requirements on the rapidity and the maneuverability of the carrier are high, and at the moment, the area of the wing needs to be reduced, the resistance of the wing is reduced, and the maneuverability is increased. The retraction of the telescopic wings is opposite to the extension described above.
First, the primary rod 8, the horizontal base 802, the two small ear plates 801, the holed closing plate 301, and the primary telescopic wing 3 are all in a stationary state with respect to the fixed wing 2. At this time, under the hydraulic control, the secondary rod 9 retracts towards the inner cavity of the primary rod 8, and drives the big lug plate 901 to retract together, and the big lug plate 901 drives the secondary telescopic wing 4 to retract towards the wing hole of the primary telescopic wing 3. When the top end of the secondary telescopic wing 4 is flush with the top end of the primary telescopic wing 3, the secondary rod 9 stops moving and stops the big lug plate 901 and the secondary telescopic wing 4, and meanwhile, under the hydraulic action, the secondary rod 9 is locked in the inner cavity of the primary rod 8, as shown in fig. 3. If the stabilizer wing area still meets the high speed sailing maneuverability requirements, the stabilizer wing area needs to be reduced continuously. At this time, under the hydraulic control, the primary rod 8 starts to retract into the hydraulic cylinder 7, the primary rod 8 drives the horizontal base 802 to retract, the horizontal base 802 drives the two small ear plates 801 to retract, and the small ear plates 801 drive the perforated sealing plate 301 and the primary telescopic wing 3 to retract into the wing holes of the fixed wing 2 until the top end of the primary telescopic wing 3 is flush with the top end of the fixed wing 2, as shown in fig. 2 and 3. At this time, because the secondary rod 9 is locked in the inner cavity of the primary rod 8, the secondary rod 9, the big ear plate 901 and the secondary telescopic wing 4 can synchronously move at the same speed and the same direction along with the movement of the primary rod 8. The two-stage telescopic wings are retracted into the wing holes of the fixed wing 2, so that the area of the stable wing of the carrier during high-speed navigation is reduced, the navigation resistance is reduced, and the maneuverability is improved.
The above description is intended to be illustrative and not restrictive, and the scope of the invention is defined by the appended claims, which may be modified in any manner within the scope of the invention.
