Swing preventing device for launching and retrieving processes of marine underwater survey equipment

Abstract

The invention relates to a swing preventing device for launching and retrieving processes of marine underwater survey equipment. A fixed seat is mounted on a deck of a survey vessel, a frame body is hinged to the fixed seat, one end of a hydraulic cylinder A is hinged to the fixed seat, the other end of the hydraulic cylinder A is hinged to the frame body, a fixed pulley is arranged on the frame body, one end of a rope is connected to the fixed seat, and the other end of the rope passes through the fixed pulley to be connected to a to-be-launched-and-retrieved marine survey instrument; a clamping arm fixing plate is hinged to the frame body, one end of a hydraulic cylinder B is hinged to the frame body, and the other end of the hydraulic cylinder B is hinged to the clamping arm fixing plate; and a hydraulic cylinder C is mounted on the clamping arm fixing plate, connecting rod mechanisms hinged to the clamping arm fixing plate are arranged on the left side and the right side of the output end of the hydraulic cylinder C correspondingly, the connecting rod mechanism on each side is connected with the output end of the hydraulic cylinder C, the other end of the hydraulic cylinder C is a clamping end for clamping the marine survey instrument, and the connecting rod mechanisms on the two sides are driven by the hydraulic cylinder C to be opened or clamped. According to the swing preventing device, swing of the marine survey instrument in the launching and retrieving processes is thoroughly prevented, and safety of marine scientific investigation operators is ensured.

Description

technical field [0001] The invention belongs to a marine deck hoisting and anti-sway device in the field of marine equipment, in particular to an anti-sway device for the deployment and recovery process of marine underwater survey equipment. Background technique [0002] Marine science is an observation-based discipline. To understand, develop and utilize the ocean, we must carry out marine surveys. Marine survey is inseparable from marine survey equipment, and the more commonly used one is the deck machinery part of the survey ship. In particular, the deployment and recovery of instruments and equipment in deep-sea surveys is inseparable from mechanical equipment with superior performance and reasonable design. Ship-borne hoisting equipment is a relatively important item of these mechanical equipment. [0003] In the process of conventional marine survey, under harsh sea conditions, during the deployment and recovery of underwater equipment, it is generally required to st...

AI Technical Summary

Problems solved by technology

The current hoisting equipment used on the rear deck of the survey ship has a simple design and structure, and can only meet the operation requirements of forward and backward swing and normal sea conditions, and cannot guarantee the safe operation of the survey equipment in and out of the water under extreme sea conditions
