Spherical manned cabin submersible cabin cover

Abstract

The invention provides a spherical manned cabin submersible cabin cover. The spherical manned cabin submersible cabin cover comprises a cabin cover body, a cabin cover fence, a torsional spring power-assisting connection mechanism, a rotating shaft and a locking mechanism, the cabin cover body is connected with the cabin cover fence through the torsional spring connection mechanism, a cabin coverinner plate is mounted in the cabin cover through a bolt, the rotating shaft is mounted on the axes of the cabin cover body and the cabin cover inner plate and penetrates through the cabin cover bodyand the cabin cover inner plate, an inner hand wheel and an outer hand wheel are arranged at the two ends of the rotating shaft correspondingly, a rotating disc is mounted on the rotating shaft, the locking mechanism is arranged on the rotating disc, the end of the locking mechanism is connected with the cabin cover body, the rotating disc is driven to rotate by rotating the rotating shaft, the locking mechanism is driven to move, and thus the cabin cover body is locked. The problem that the cabin cover fence is formed on a cabin body in a machined mode, consequently, the shell structure is damaged, clamping force is distributed unevenly, and consequently the sealing effect is poor is solved, and the underwater water tightness, reliability and safety of the cabin cover are improved.

Description

technical field [0001] The invention relates to a hatch cover of a spherical manned cabin submersible, which belongs to the field of submersible equipment. Background technique [0002] With the continuous development of the ocean and the development of marine tourism, the demand for manned submersibles continues to increase. As one of the core components of the manned submersible, the access hatch cover is directly related to the safety and reliability of the personnel in the cabin and whether the equipment in the cabin can operate reliably. Therefore, the hatch cover should have high reliability. At the same time, the hatch cover locking mechanism should be easy to operate, convenient for the operator to lock and unlock, and should have the function of unlocking both inside and outside the cabin, so as to facilitate rescue in emergency situations. [0003] Most of the material of the cabin of the existing manned submersible is metal, and the hatch cover fence is fixed wi...

AI Technical Summary

Problems solved by technology

For the locking mechanism of the hatch cover, some of them adopt multi-point locking structures respectively, but this scheme is cumbersome to operate on the one hand, and on the other hand, it cannot ensure the uniform distribution of the pressing force, which will affect the gap between the hatch cover and the hatch cover frame. The sealing has adverse effects; the rotating shaft of the locking mechanism is often fixed with the transmission thread and the hatch cover, but the transmission thread is easy to wear, which will cause the self-locking performance of the thread to deteriorate, and also reduce the sealing performance
