Securing device of one man atmospheric diving apparatus

Abstract

The invention provides a securing device of a one man atmospheric diving apparatus. The lashing device comprises a released hook, a hoisting mechanism, a horizontal swinging mechanism and a vertical rotating mechanism, wherein the hoisting mechanism comprises a mounting frame; the mounting frame is provided with a vertical screw rod; the screw rod is in threaded connection with a nut; the screw rod is connected with a transmission device on the mounting frame; the nut is fixedly connected with a sliding bracket; the sliding bracket is in sliding match with a vertical guide rail on the mounting frame; the horizontal swinging mechanism comprises swinging oil cylinders at the two sides of the released hook; the released hook is connected with a base through a rotary shaft; the swinging oil cylinders are symmetrically arranged relative to the rotary shaft; piston rods of the swinging oil cylinders are connected with the released hook; the swinging oil cylinders are arranged on the base; the base is in pin joint with a connecting rod; the connecting rod is in pin joint with the sliding bracket; the vertical rotating mechanism comprises a securing oil cylinder; the securing oil cylinder is in pin joint with the sliding bracket; a piston rod of the securing oil cylinder is in pin joint with a rotary plate; and the two ends of the rotary plate are respectively in pin joint with the sliding bracket and the base. According to the lashing device disclosed by the invention, the one man atmospheric diving apparatus in a relay station is effectively secured; and the safety protection effect on the apparatus is realized.

Description

technical field [0001] The invention relates to the technical field of underwater operation devices, in particular to underwater operation devices applied to underwater moving bodies such as deep-sea remote control robots, single-person atmospheric pressure diving equipment, deep-sea space stations, and submarines, especially to underwater operation devices applied to single-person atmospheric pressure diving The securing device used in the system to secure the one-person atmospheric diving suit entering the relay station. Background technique [0002] The single-person atmospheric pressure diving system is mainly composed of three parts: the single-person atmospheric pressure diving suit 100 (ADS), the relay station 200 (TMS) and the surface deployment and recovery system 300 (LARS). figure 1 As shown, the relay station 200 carries the single-person atmospheric pressure diving equipment 100 and is hoisted by the surface deployment recovery system 300 through the armored cab...

AI Technical Summary

Problems solved by technology

The traditional way of connecting the equipment and the relay station is a one-point connection. From a mechanical point of view, this single-point support is an unstable support. The single-point support has the following defects: during the deployment and recovery of the equipment, due to the current Due to the impact and instability of the support, the equipment will rotate and shake, and the divers in the equipment will have adverse physiological reactions such as dizziness. If the external disturbance is too large, the equipment may also collide and rub against the lower part of the relay station. Cause damage to the harness, and may even cause meshing failure, and once the meshing device fails, the effective restraint between the harness and the relay station will be lost, and the harness may fall into the seawater from the clutch, causing a safety accident
