Novel water surface salvage cable robot built-in connecting mechanism

Abstract

The invention relates to a mechanism for connecting two components, in particular to a novel built-in connecting mechanism for water surface salvage cable robots, which connects a cylinder body and a ball end body or a tail cone body. The connecting mechanism comprises a connecting ring plate, wherein a plurality of flanges are evenly distributed on the outer wall of the connecting ring plate; one side surface of the connecting ring plate is provided with at least one stop key; a plurality of protrusions are evenly distributed on the outer wall of a cylinder body connecting end; axial insertion grooves corresponding to the flanges are formed between every two adjacent protrusions; the connecting ring plate is inserted into the end part of the cylinder body connecting end through the axialinsertion grooves; the end part of the cylinder body connecting end is provided with a radial ring groove for holding the connecting ring plate; a connecting screw is arranged on the ball end body orthe tail cone body and is connected with the connecting ring plate; and O-shaped sealing rings are respectively arranged between the connecting screw and the ball end body or the tail cone body as well as between the ball end body or the tail cone body and the cylinder body. The connecting mechanism is also applicable to the detachable connection among cylindrical parts in other fields, and has the advantages of compact and reliable connection, capability of reducing underwater resistance for robots, simple and rapid operation and wide application range.

Description

technical field [0001] The invention relates to a mechanism for connecting two components, in particular to a new type of built-in connection mechanism for a cabled robot for surface rescue. Background technique [0002] As a surface rescue robot navigating in water, it is composed of upper and lower buoys and two propellers. Through reliable and detachable axial connections, it forms a smooth and rounded whole. When the robot was navigating on the water surface, the lower buoys were all immersed in the water, while the upper buoys were partially (half) immersed in the water. Therefore, in order to reduce the resistance of the robot running in water, it is required in the structural design of the robot that the outer surfaces of the upper and lower buoys should be as smooth as possible, without other unnecessary external structures and raised structures. [0003] However, most of the detachable connection methods between the existing cylindrical parts are flange connection...

AI Technical Summary

Problems solved by technology

Since the outer flanges and bolts of the connecting flange are exposed on the outside of the structure, not only there is a sudden change in the structure, but also the size of the section increases, which increases the driving resistance of the robot in water. Obviously, this traditional connection method is not suitable for Surface rescue cable robot
