Concave-convex underwater butt joint device

Abstract

The invention provides a concave-convex underwater butt joint device. The butt joint device comprises a telescopic skirt, a telescopic mechanism for controlling the telescopic skirt to move, a primaryconnecting ring arranged on the telescopic skirt, a butt joint platform and a mechanical arm body arranged on the butt joint platform. The mechanical arm body is matched with the primary connecting ring; the telescopic skirt comprises a submersible vehicle connecting plate connected with the submersible vehicle, a fixed skirt arranged at the lower end of the submersible vehicle connecting plate,and a movable skirt arranged outside the fixed skirt; the primary connecting ring is arranged outside the movable skirt, annular protrusions with trapezoidal sections are arranged at the lower end ofthe fixed skirt and the lower end of the movable skirt respectively, locking mechanisms matched with the annular protrusions are arranged at the upper end of the movable skirt and the upper end of thebutt joint platform respectively, and a sealing mechanism is arranged between the movable skirt and the contact face of a skirt opening in the butt joint platform. According to the invention, underwater butt joint operation can be completed simply, conveniently, rapidly, accurately and reliably under unknown sea conditions.

Description

technical field [0001] The invention relates to a concave-convex underwater docking device, which is a material and personnel exchange device for connecting underwater submersibles and ocean space stations, and is applied to underwater docking between submersibles and ocean development operations. Background technique [0002] The earth is not really a "terrestrial" ball, but a water sphere, and the ratio of land to ocean on the earth is about 0.43. Most of the earth's area is ocean, and the ocean has a lot of resources. With the development of society, human beings need more resources. The decrease of land resources, the increase of the population base, the dependence on resources, and the future development of the vast ocean increasingly important. The development and utilization of marine resources has become a scientific research project that countries are competing to invest in research and development. Submersibles, ships, ocean platforms and undersea space stations ...

AI Technical Summary

Problems solved by technology

The docking devices of early underwater vehicles have fixed docking skirts and rotating docking skirts. Although they have their own advantages, in unknown sea conditions, the success rate of docking operations is low, and docking cannot be realized actively
