The invention discloses an underwater pressure-bearing sealed cylinder and a preparation method thereof. The underwater pressure-bearing sealed cylinder comprises a front part, a middle part and a rear part, wherein the front part takes the shape of a centrosymmetric spherical cap; the middle part is cylindrical; the rear part adopts a convergent shape; the front, middle and rear parts are all connected with one another through convex platforms and concave platforms; the convex and concave platforms are mutually matched in shape; grooves used for placing of sealing rings are formed in the contact planes of the convex and concave platforms, and lower than the sealing rings; sealing rings used for angle sealing are also arranged at the contact ridges of the convex and concave platforms. The underwater pressure-bearing sealed cylinder has the characteristics of being beautiful in fluid appearance, high in strength, pressure resistance and water tightness, relatively light in structural weight, relatively large in internal accommodating space, low in cost, and the like; the requirements for a relatively high depth of underwater sinking, high navigation maneuverability and the like can be met; the maximum fluid static loads and dynamic loads during sinking and navigation can be born.
