Abstract

The invention discloses a multi-ball conjoined manned cabin of a large-diving-depth submersible, which consists of a plurality of spherical shell cabin sections, wherein each spherical shell cabin is connected through a cylindrical shell transition section structure, the spherical shell cabin sections and the transition sections are formed by forging, the central circumferential direction of the transition sections is welded, so that the two spherical shell cabin sections form an integral conjoined structure, and the connection part of the spherical shell cabin sections and the transition sections extends in the inner cavity of the transition sections to form reinforcing ribs. The thickness control of the welding part of the transition section shell can bear larger water pressure and can submerge to a deeper depth under the condition that the welding can be completed by the existing welding process.

Description

Multi-ball conjoined manned cabin of large-diving-depth submersible Technical Field The invention relates to the technical field of diving equipment, in particular to a multi-ball conjoined manned cabin of a large diving depth submersible. Background With the continuous development of the fields of ocean resource development, deep sea scientific research and the like, the demand for large submersible vehicles is growing. The traditional multi-cabin submersible has a plurality of defects in structural design, such as limited space of the submersible with a single cabin structure, difficult meeting the complex operation requirement, complicated and complex connection mode of the traditional multi-cabin submersible in process realization, and the welding position just coincides with a larger stress area, so that the structure damage of the cabin section connection position is easy to occur under a large-depth hydraulic environment, or the problems of sealing leakage and the like are faced when flange connection is adopted, and the safety and the reliability of the submersible are seriously affected. In order to improve the safety of the connecting part of the large submerged cabin, the thickness of the connecting part of the cabin needs to be increased, and if the connecting part of the cabin is formed by welding, the welding process is limited, and the upper limit of the thickness of the connecting part exists, so that the whole submersible cannot realize large submerged depth. If the bolts are used for connection, flange connection is added, weight is increased, and meanwhile, tightness of the connection part is guaranteed, so that leakage is easy under the environment of large submergence depth. Therefore, there is a need to design a multi-ball conjoined manned cabin of a large diving device with reasonable structure, stable connection and good compression resistance. Disclosure of Invention The invention aims to provide a multi-ball conjoined manned cabin of a large-diving-depth submersible, wherein a reinforcing rib is arranged at the joint of the cabin section, so as to solve the technical problems in the prior art. In order to solve the technical problems, the invention specifically provides the following technical scheme: A large diving depth submersible multi-ball conjoined manned cabin comprising: the cabin section is a spherical shell; the cabin comprises a cabin section, a transition section, a reinforcing rib, a connecting piece and a connecting piece, wherein the transition section is arranged between the cabin sections, is a cylindrical shell, is communicated with the transition section and is integrally formed; the reinforcing ribs are arranged in parallel relative to the welding positions of the two transition sections. Further, the inner side wall of the joint of the reinforcing rib and the cabin section is in arc transition with an opening facing the inside of the submersible, so that a first transition section is formed. Further, the outer side wall of the joint of the transition section and the cabin section is in arc transition with an opening facing the outside of the submersible, so that a second transition section is formed.
