Separated type actuating mechanism for deep-sea visual sampler

Abstract

The invention provides a separated type actuating mechanism for a deep-sea visual sampler and belongs to the technical field of deep-sea hydrothermal area investigating, detecting and sampling equipment. The separated type actuating mechanism comprises a peripheral non-load-bearing framework, a load bearing structure, a grab bucket and a grab bucket hydraulic cylinder, wherein the load bearing structure, the grab bucket and the grab bucket hydraulic cylinder are arranged in the framework; the top of the grab bucket is fixed to the upper part of the peripheral non-load-bearing framework throughthe load bearing structure, two bucket-shaped jaw plates of the grab bucket are respectively driven by the grab bucket hydraulic cylinder, and the top end of a piston rod of the grab bucket hydrauliccylinder is in rotary connection with the middle of the bottom end of the load bearing structure; the top of the load bearing structure is separately connected with a control system of the actuatingmechanism through two separated type lifting point connection mechanisms which are distributed in the direction perpendicular to the axial direction of the grab bucket hydraulic cylinder, and a cameraand a lighting lamp are arranged in the load bearing structure. By means of the separated type actuating mechanism disclosed by the invention, the deep-sea visual sampler can flexibly change operation tools according to target objects when job tasks are executed; thus, functions are expanded, and an operation efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of investigation, detection and sampling equipment in deep-sea hydrothermal areas, and in particular relates to a separate actuator of a deep-sea visual sampler (DCVS). Background technique [0002] In recent years, the exploration of deep-sea hydrothermal areas has become a hot spot in international ocean surveys, and it is highly dependent on the performance of exploration equipment. At present, the main detection and sampling equipment used in the investigation of deep-sea hydrothermal areas include: submersibles, deep-sea towing systems (referred to as "deep towing systems"), and television grabs. Among them, a submersible is a device that can move underwater, has a vision and perception system, and uses tools such as manipulators to replace or assist humans to complete certain underwater operations through remote control or autonomous operation. There are many types of submersibles, among which manned ...

Problems solved by technology

However, ROV also has certain limitations: ROV operation is complicated, and it needs to be operated and maintained by specially trained personnel. Usually, a complete ROV operation and maintenance team needs at least 4 to 8 people; With the cooperation of advanced equipment, the time period is long and the efficiency is low; the design of ROV uses floating body materials to achieve the purpose of free movement on the seabed. ROV cannot be replaced or loaded with other modules at will, otherwise there will be a mismatch between buoyancy and gravity. ROV does not have The large weight carrying capacity has certain restrictions on the volume and weight of collected samples; the ROV's working environment is extremely complex and changeable, and it is easy to be blocked, collided or even stuck by some undetectable obstacles in the deep sea, and then damaged, lost, and caused huge loss

The traditional TV grab does not have the support function of the bottom bracket, and it is easy to dump during the sampling process; the working tools cannot be replaced according to different operation requirements, and the execution efficiency is low; the entire sampler needs to be discarded in case of an accident
