Problems solved by technology

Among them, the latitudinal radius of the ribless cylindrical shell is infinite, resulting in low buckling load and poor compressive capacity under underwater high pressure conditions, and there are multiple modes of the same root, which are sensitive to initial geometric defects, and the manufacturing and installation accuracy requirements high
[0004] The ring-ribbed cylindrical shell is strengthened by a number of discrete circular ribs, which improves the compressive capacity and reduces the defect sensitivity to a certain extent, but its latitudinal radius is still infinite, which makes it prone to intercostal instability

Embodiment Construction

[0022] Such as figure 1 , the pressure device of the manned submersible is composed of three parts: the observation window head 2, the pressure shell 1 and the hatch door head 3, and the observation window head 2 and the hatch door head 3 are respectively installed at both ends of the pressure shell 1.

[0023] Such as figure 2 , the pressure shell 1 is a bionic spiral cylindrical pressure shell 1, and the spiral layer curve of the pupa snail is scanned to obtain the spiral layer curve, and the intercostal busbar equation is obtained by using software to fit the curve:

[0024]

[0025] Wherein, B is the height of the busbar, L is the span of the busbar, n is the shape factor of the busbar, and the shape factor of the busbar of the chrysalis is 0.06-0.16, preferably 0.114. After determining the span L of the busbar, the profile of the busbar between the ribs can be obtained; the spiral rib is a T-shaped rib, which enhances the axial and radial compression resistance. The...

Abstract

The invention discloses a pressure-resistant device for a manned submersible, which comprises a pressure-resistant shell. The two ends of the pressure-resistant shell are respectively an observation window head and a cabin door head. The door head and the pressure shell are connected by screws, and the pressure shell is a bionic spiral cylindrical pressure shell. Compared with the prior art, the present invention has the following remarkable features: the present invention adopts the bionic spiral cylindrical shell as the main body of the pressure-resistant device, which is beneficial to reduce the defect sensitivity of the pressure-resistant shell, is beneficial to avoid intercostal instability, and is beneficial to improve Axial and radial pressure resistance; the hatch of the present invention is provided with a pressure sensor, which can detect the pressing force of the hatch door, which is beneficial to judge the locking state of the hatch door according to the pressing force of the hatch door; the lock of the locking device of the present invention The contact surface between the tight pin and the ring groove is an inclined plane, and turning the handle will gradually increase the pressing force of the hatch, which is beneficial to improve the sealing effect.

Description

technical field [0001] The invention relates to the field of diving equipment, in particular to a pressure-resistant device for a manned submersible. Background technique [0002] The cylindrical pressure hull is an important device and buoyancy unit of a large-space deep-sea submersible, which plays a role in ensuring the normal operation of internal non-pressure-resistant equipment and the safety of personnel during the dive. [0003] The existing cylindrical pressure-resistant shells are mainly non-finned cylindrical shells and ring-ribbed cylindrical shells. Among them, the latitudinal radius of the ribless cylindrical shell is infinite, resulting in low buckling load and poor compressive capacity under underwater high pressure conditions, and there are multiple modes of the same root, which are sensitive to initial geometric defects, and the manufacturing and installation accuracy requirements high. [0004] The ring-ribbed cylindrical shell is strengthened by a numbe...
