Embodiment 1

[0047] figure 1 It is a schematic diagram of the overall structure of the underwater pressure-bearing sealing cylinder according to the preferred embodiment of the present invention. Such as figure 1 As shown in , the sealing cylinder mainly includes a front part 1, a middle part 2 and a rear part 3. The front part 1 has a semi-ellipsoidal shape structure, which can effectively reduce the movement resistance of the underwater pressure-bearing sealing cylinder when navigating underwater. The rear part 3 is a convergent structure, and 8 stabilizing wings 4 are evenly distributed, which can effectively increase the stability of the attitude of the underwater pressure-bearing sealing cylinder when navigating underwater; Internal equipment maintenance and fault diagnosis. The middle part 2 is a cylindrical structure, which is integrally connected with the front part 1 and the rear part 3 by screwing. The length of the sealing cylinder can be adjusted by increasing or decreasing ...

Embodiment 2

[0076] The parameters of embodiment 2 are basically the same as those of embodiment 1, the differences are:

[0077] The element composition and the mass percentage of each element of the aluminum alloy raw material are as follows: Si 10.5%, Mg 0.35%, Mn 0.5%, Sr 0.06%, Cu0.09%, Zn 0.24%, Ti+Zr 0.14%, Sn 0.009%, Pb 0.04%, Fe0.5%, B 0.07%, the balance is Al.

[0078] After the casting is prepared, the casting is kept at a temperature of 530° C. for 360 minutes for solution treatment; then, the casting is kept at a temperature of 160° C. for 240 minutes for aging treatment.

Embodiment 3

[0080] The parameters of embodiment 3 are basically the same as those of embodiment 1, the differences are:

[0081] The elemental composition of the aluminum alloy raw material and the mass percentage of each element are as follows: 8% Si, 0.17% Mg, 0.2% Mn, 0.02% Sr, 0.01% Ti+Zr, 0.005% B, and the balance is Al.

[0082] After the casting is prepared, the casting is kept at a temperature of 530° C. for 360 minutes for solution treatment; then, it is kept at a temperature of 170° C. for 300 minutes for aging treatment.

Abstract

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.

Description

technical field [0001] The invention belongs to the field of underwater detection vehicles, and more particularly relates to an underwater pressure-bearing sealing cylinder for underwater vehicles and a preparation method thereof. Background technique [0002] The pressure-bearing sealing cylinder working in the underwater environment, as the shell of the underwater vehicle, its shell structure and connection must meet the two basic requirements of pressure resistance and long-term watertightness, and at the same time try to pursue the minimum structural weight (thin and light) and high strength). [0003] Hydrostatic pressure is the most basic and important external load on the shell of the sealing cylinder. At the same time, the structural characteristics of the sealing cylinder (including material selection, configuration, strength and stability, mode and connection sealing method) should also meet the requirements of transportation, hoisting And the influence of dynamic...
