[0002] At present, underwater vehicles are widely used in the fields of marine scientific research, marine engineering, marine resource exploration, military reconnaissance, etc. In recent years, with the development of sensor technology and information technology, underwater vehicles have received more and more attention and have become a hot spot for the development of marine engineering, further promoting the development of autonomous unmanned underwater vehicles towards intelligence, integration, and refinement; among them, the device that crosses the air and water medium, transforms in the two media, and realizes amphibious navigation is called a cross-medium device. This type of device has obvious advantages and can take into account the speed of the aircraft and the concealment of the submersible. It can be used for underwater environmental detection and water rescue. However, when these devices cross different media, they often face the problem of excessive energy loss caused by damping changes, especially the technical challenges of amphibious vehicles in the cross-medium conversion process are particularly prominent, which has become a major problem restricting the development of cross-medium submersibles.

[0023] A telescopic underwater vehicle comprises a front cabin 2 and a rear cabin 3, a vehicle connecting plate 1 is fixedly installed on the right side of the front cabin 2, the rear cabin 3 is telescopically installed on the right side of the vehicle connecting plate 1, and a center of gravity transfer component is provided in the rear cabin 3, the left side of the rear cabin 3 is closely attached to the right side of the vehicle connecting plate 1, four storage grooves 6 distributed in a circular array are opened on the vehicle connecting plate 1, and a take-off component is provided in the storage groove 6, and the outer surfaces of the front cabin 2 and the rear cabin 3 are fixedly connected with balance wings.

[0024] Specifically, the take-off assembly includes an electric push rod 7, a drive motor 8 and a rotor 9. The electric push rod 7 is fixedly installed at the bottom of the storage slot 6, and the output end of the electric push rod 7 is fixedly connected to the drive motor 8. The output shaft of the drive motor 8 is fixedly installed with the rotor 9, and the rotor 9 is located in the storage slot 6, and the output shaft of the drive motor 8 faces the front cabin 2.

[0025] Specifically, the left end of the front cabin 2 is fixedly connected with the bow 4, and the right end of the rear cabin 3 is installed with a ducted propeller 5 to provide power for the underwater vehicle.

[0026] Specifically, an adjusting screw 101 is rotatably installed at the center of the right side of the aircraft connecting plate 1, and a plurality of guide rods 102 arranged parallel to the adjusting screw 101 are fixedly connected to the right side of the aircraft connecting plate 1. The center of gravity transfer assembly includes a counterweight 103, which is threadedly installed on the adjusting screw 101, and the counterweight 103 is slidably sleeved on each guide rod 102. The edge of the counterweight 103 is fixedly connected to the inner wall of the rear cabin 3. A servo motor 104 is fixedly installed on the left side of the aircraft connecting plate 1, and the output shaft of the servo motor 104 is fixedly connected to the left end of the adjusting screw 101.

[0027] Specifically, a plurality of telescopic rods 302 are fixedly connected to the right inner wall of the rear cabin 3, and the other end of the telescopic rod 302 is slidably connected in the guide rod 102. Four sealing cover plates 301 distributed in a circular array are fixedly connected to the outer side of the rear cabin 3. The sealing cover plates 301 slide in contact with the outer side of the aircraft connecting plate 1, and the sealing cover plates 301 cover the notches of the storage slots 6. When sailing underwater, the rotor 9 is stored in the storage slots 6 for protection, and the sealing cover plates 301 seal the storage slots 6 to prevent foreign objects from entering.

[0028] Specifically, a floatation air chamber 201 is provided in the front cabin 2. Inflation of the floatation air chamber 201 will increase the buoyancy of the front cabin 2, so that the front cabin 2 can float to the water surface.

[0029] The specific implementation of this embodiment is as follows: initially, the underwater vehicle is parallel to the horizontal plane, so that it can sail in the water to the designated area. At this time, the rear cabin 3 is against the vehicle interface plate 1, so that the front cabin 2, the vehicle interface plate 1 and the rear cabin 2 are integrated, reducing the power assistance. When the posture is switched, the servo motor 104 works and drives the adjustment screw 101 to rotate, so that the counterweight block 103 moves along the guide rod 102 and away from the front cabin 2 to adjust the center of gravity. At the same time, the counterweight block 103 drives the rear cabin 3 to move, and the telescopic rod 302 moves on the guide rod 1 02 slides inside to ensure the stability of telescoping.

Subsequently, the electric push rod 7 works to move the drive motor 8 out of the storage slot 6. The drive motor 8 works to drive the rotor 9 to rotate, thereby making the underwater aircraft fly off the water surface.

[0030] The rotation of the adjusting screw rod 101 is controlled by the servo motor 104 to adjust the position of the counterweight 103, thereby changing the center of gravity, so that the underwater vehicle can cross the medium in a vertical posture on the water surface, reduce the damping when crossing the medium, and reduce the loss of required energy, thus realizing sea and air amphibious operation, overcoming the uncertain factors that affect the stable navigation of the submersible in the underwater environment, and enabling the underwater vehicle to have stable water-air navigation and reliable cross-medium capabilities.
