The invention discloses a sinking and floating device for a small underwater vehicle. The device adopts a stepping motor as a driving mechanism; the stepping motor drives a lead screw to rotate, and the lead screw and a nut cooperate to drive a middle support plate to move, and the middle support plate drives two pistons When the mechanism moves, it absorbs water or discharges water synchronously, so that the water storage volume in the two piston cylinders changes. The diameter of the suction and discharge port of the piston cylinder is small, and the water flows through the piston rod to drive the rubber piston to quickly inhale or discharge the piston cylinder, changing the gravity of the aircraft; when the suction and drainage are produced, the force is generated and controls the attitude adjustment of the aircraft and the speed of ups and downs, changing the navigation. The gravity of the aircraft makes the aircraft produce downward or upward acceleration to realize the ups and downs of the aircraft. The vehicle sinking and floating device has small structural size and light weight, can precisely control the suction and displacement, and enhances the adaptability and operation ability of unmanned underwater vehicles in complex environments. The sinking and floating device is highly expandable and can be applied to small underwater robots and other small underwater delivery devices.

The invention relates to a naturally-energy-driven wing-rudder linkage long-endurance twin-hull unmanned boat, and belongs to the field of unmanned boats. The naturally-energy-driven wing-rudder linkage long-endurance twin-hull unmanned boat comprises a twin-hull sheet body, four wave swinging hydrofoils, wing-rudder linkage mechanisms, hydrofoil mounting plates, a solar panel, a wind generator and a fan bracket. Two of the swinging hydrofoils are arranged at the bow and two of the swinging hydrofoils are arranged at the stern, and the swinging hydrofoils are arranged side by side in the widthdirection of a hull. The arrangement method overcomes the structural weight gain burden when the wings are greatly expanded. The front and rear hydrofoils extend towards the bow and the stern correspondingly, so that the hydrofoils utilize the longitudinal motion of the hull in waves and the heave amplitude is larger than the heave amplitude of the bow and the stern of the sheet body, and thus the thrust generated by the hydrofoils is effectively improved. The wing-rudder linkage mechanisms adopt hydraulic transmission devices, the thrust of the hydrofoils on the left side and the right sideof the hull is changed by limiting the rotation range of the swinging hydrofoils on the left side and right side of the hull, a thrust difference is generated to drive the unmanned boat to rapidly rotate the bow, and when the rotation of all the hydrofoils are limited at the same time so that the unmanned boat cannot generate thrust, the unmanned boat can quickly stop, and therefore, the unmannedboat has the capability of rapidly rotating the bow and stopping in an emergency.
