Underwater automatic docking mechanism for ROV

Abstract

The invention relates to an underwater automatic docking mechanism for an ROV(remotely operated vehicle). The underwater automatic docking mechanism comprises a mounting seat, wherein an axial hole and a radial through slot I which are in communication are formed in the mounting seat; an oil cylinder piston rod extends into the axial hole, and a pushing head is hinged to the piston rod; the mounting seat is fixedly connected with a conical guide head with a radial through slot II, and the two radial through slots communicate to form mounting spaces for locking blocks, and the two locking blocks are symmetrically arranged on two sides of the pushing head; the locking blocks are hinged to one side wall of the radial through slot I, the shape of the cross section of each of the locking blocks is triangular, and springs are connected between the locking blocks and the bottom of the radial through slot II; under the action of the springs, the end surfaces of the outer sides of the two locking blocks are at the vertical positions or the lower ends of the two locking blocks are close to the tilted position of the axis of the mounting seat, and the tops of the two locking blocks are in docked connection with the bottom of the pushing head; a docking block is provided with an axial through hole, and an outwards-expanding tapered hole is formed in the lower part of the axial through hole; during docking, the mounting seat extends into the axial through hole, and the locking blocks are driven by the oil cylinder to rotate, until the end surfaces of the outer sides of the locking blocks are in docked connection with the wall surface of the tapered hole. According to the underwater automatic docking mechanism, the automatic docking of the ROV and underwater equipment can be realized.

Description

technical field [0001] The present invention relates to the technical field of underwater operation devices, in particular to underwater operation devices applied to underwater cable-controlled moving bodies such as remote-controlled underwater robots and single-person atmospheric pressure diving equipment, and in particular to remote-controlled underwater vehicles. The mechanism that can realize the fast and accurate docking of the remote control submersible and the underwater lifting object in the operation of hoisting to the water surface. Background technique [0002] Remotely operated vehicle (ROV) is a kind of underwater robot. It is a high-tech equipment that can work in an underwater environment for a long time. The advantages. ROV has become an effective means for underwater installation and maintenance operations in offshore oil exploration projects due to its strong operating capacity, multiple operating functions, high reliability and safe remote operation.

Problems solved by technology

[0003] At present, there is an underwater operation toolkit developed for ROV manipulators. The underwater operation toolkit is directly connected to the robotic arm, and the manipulator can be used to directly grasp and hold the tool to perform other operations such as maintenance of underwater equipment. However, for some Equipment for underwater maintenance and other operations needs to be hoisted to the surface mother ship for maintenance and other operations. On the other hand, the ROV manipulator has limited grasping capacity, which brings certain difficulties to underwater equipment maintenance or replacement. Therefore, it is necessary to A docking mechanism to realize the docking of remotely controlled submersibles and underwater equipment, so as to facilitate the transfer of underwater equipment to the surface mother ship

There is no corresponding docking mechanism in the prior art to realize the automatic docking of ROV and underwater equipment
