Ultrahigh pressure large-diameter anti-shear block loading, unloading and locking mechanism for simulator under deep ocean environment

Abstract

The invention relates to an ultrahigh large-diameter anti-shear block loading, unloading and locking mechanism for a simulator under the deep ocean environment. The anti-shear block loading, unloading and locking mechanism comprises a pressure drum; a sealing cover is arranged at the top of the pressure drum; a shearing slot is formed in the inner ring surface of the upper part of the pressure drum; anti-shear blocks are arranged and positioned on the sealing cover; the anti-shear blocks are clamped in the shearing slot formed on the pressure drum; the anti-shear blocks comprise oblique anti-shear blocks and straight anti-shear blocks which are arranged at the top of the sealing cover at intervals and encircle by one circle; a bearing block is arranged in the middle of the sealing cover; the mechanism also comprises an oil cylinder seat; an oil cylinder is arranged on the oil cylinder seat; the oil cylinder seat and the bearing block are integrally assembled by a bearing, so an anti-shear block loading and unloading device is formed. The anti-shear block loading, unloading and locking mechanism is flexible and reliable in use and high in work efficiency.

Description

technical field [0001] The invention relates to an auxiliary device of a pressure vessel, especially a shear block loading and unloading and locking mechanism applied to a deep-sea ultra-high pressure environment simulation and detection device, and can also be used on a pressure vessel that needs to frequently open the cover, or other devices with On equipment in the form of shear block structures. Background technique [0002] Deep-sea submersibles and related equipment are the main tools for human beings to conduct deep-sea scientific research, deep-sea environmental monitoring, and deep-sea resource exploration, development, utilization and protection. While developing deep-sea submersibles and related equipment, the world's marine powers all pay great attention to the basic test capabilities of deep-sea equipment, and have successively built a series of deep-sea simulation test devices including deep-sea simulation test systems. The development provides an ultra-high p...
