Fast hook device for ROV suspension

Abstract

The invention discloses a fast hook device for ROV suspension. The hook device comprises an umbilical cable, a bearing steel cable, an unlocking string and a shackle and further comprises a hook device body connected through the umbilical cable. The hook device body is of an internally hollow structure. A hook device matching piece matched with the hook device body and a connecting fixed seat are sequentially connected below the hook device body through the umbilical cable from top to bottom. The umbilical cable sequentially penetrates the center of the hook device body, the center of the hook device matching piece and the center of the connecting fixed seat and then is fixedly connected with an ROV. An unlocking mechanism and locking mechanisms are further arranged on the hook device body. The unlocking mechanism is mounted on one side end face of a hook device shell of the hook device body through a sliding pin seat. The locking mechanisms are symmetrically mounted on the two sides of the hook device shell of the hook device body through screws. The unlocking string is connected to a sliding pin shaft of the unlocking mechanism. The fast hook device is simple in structure and convenient to operate, water suspension can be fast and safely achieved on the ROV, and the safety of personnel and equipment is greatly guaranteed.

Description

technical field [0001] The present invention relates to a hook device, in particular to a quick hook device for hoisting and launching an ROV, which is mainly used for lifting the ROV from the working water surface to the deck or lowering the ROV from the deck to the working water surface. Background technique [0002] Generally speaking, ROV is a remotely operated submersible, which is connected to the water surface through an umbilical cable, and the umbilical cable realizes power supply, operation control and data transmission to ROV on land. [0003] Specifically, the cabled underwater robot ROV (Remote Operated Vehicle) is powered and functionally controlled by the surface equipment through the umbilical cable, and the operation is completed by the surface control personnel. Usually, the umbilical cable of ROV with cable is zero-buoyancy cable, which has a certain carrying capacity. However, due to the difficulty of reliable connection between the umbilical cable and RO...

AI Technical Summary

Problems solved by technology

With the increasing application of ROV, such as in offshore oil, scientific research and other fields, the carrier of ROV is a platform or a large ship, and the distance between the working platform and the water surface is generally greater than 6m. Big potential safety hazard, and the operation is time-consuming and labor-intensive

Another example is in the fields of hydropower dams, energy storage power station pipeline inspection and other fields, the distance between the land and the water surface is generally greater than 10m, and it is difficult for personnel to reach the water surface for hooking or uncoupling operations in the narrow hole space. In short, it greatly affects the application field of ROV
