Telescopic submarine
A telescopic submarine includes: a front submarine unit (1), a rear submarine unit (2), and a lift tower (3). A ring-shaped piston (14) connected with the rear submarine unit (2) is in a hydrocylinder (7) connected with the front submarine unit (1). When the piston (14) is moved forward, a volume of the telescopic submarine is decreased, a specific gravity of the telescopic submarine is increased, and therefore the telescopic submarine dives into the water gradually. The telescopic submarine is able to surface via operating the horizontal rudder (20) to raise the telescopic submarine to a surface of the water, and then pumping the hydraulic oil (32) into the hydrocylinder (7) via the hydraulic pump (11) to drive the piston (14) to move backward. Therefore the volume of the telescopic submarine is increased, the specific gravity of the telescopic submarine is decreased, and the telescopic submarine surfaces.
