Title:
LARGE-DEPTH UNDERWATER VEHICLE, PRESSURE-RESISTANT SHELL FOR LARGE-DEPTH UNDERWATER VEHICLE AND ASSEMBLING METHOD OF PRESSURE-RESISTANT SHELL
Document Type and Number:
WIPO Patent Application WO/2021/169680
Kind Code:
A1
Abstract:
A large-depth underwater vehicle, a pressure-resistant shell for the large-depth underwater vehicle and an assembling method of the pressure-resistant shell. The pressure-resistant shell for the large-depth underwater vehicle is a composite structure and comprises a shell outer plate (11), an outer-layer shell (12), an inner-layer shell (13) and a shell inner plate (14) that are sequentially and coaxially arranged from outside to inside, a pressure-resistant structure is arranged between the inner-layer shell (13) and the outer-layer shell (12), and the pressure-resistant structure comprises a plurality of frustum-shaped first rib units (15) which are uniformly arranged on the outer surface of the inner-layer shell (13) at equal intervals; and the inner surface of the outer-layer shell (12) is provided with a plurality of frustum-shaped second rib units (17) corresponding to the first rib units (15), and the first rib units (15) and the second rib units (17) are arranged in a staggered and overlapped mode so that radial force borne by the shell can be converted into in-plane force on the side walls of the rib units (15, 17). The structure improves the reserve buoyancy, and the safety of the pressure-resistant shell and the underwater vehicle.
