Carrying device for underwater movable platform of remote control submersible

Abstract

The invention relates to a carrying device for underwater movable platform of a remote control submersible, which is arranged in a non-pressure resistant structure at the top of an underwater movable platform. The underwater movable platform carrying device is characterized by comprising a traction winch and a guiding hoistable platform, wherein the traction winch is connected with the guiding hoistable platform through a traction steel cable and a fixed pulley block; a neutral cable retractable winch for receiving and releasing a neutral cable of the remote control submersible is arranged above the traction winch; a guiding positioning block of the guiding hoistable platform guides and positions the remote control submersible; and a capture locking mechanism of the guiding hoistable platform locks the remote control submersible. The underwater movable platform carrying device has the advantages of reducing the space occupation of the underwater movable platform, lightening the carrying weight of the underwater movable platform, along with simple and reliable structure, light weight, simple arrangement and recovery operation and recovery and high efficiency, and is suitable for carrying the remote control submersible by utilizing top space through the underwater movable platform and for arranging and recovering the remote control submersible from the back of the underwater movable platform.

Description

technical field [0001] The invention relates to an underwater operation equipment, in particular to an underwater mobile platform carrying device of a remotely controlled submersible. Background technique [0002] For remote-operated vehicles (ROVs) operating in deep sea, deployment and recovery are usually carried out by surface ships. When the surface ship deploys and recovers the ROV, it usually proceeds through a relay station (TMS) or a recovery cage (garage). When deploying, the surface ship lifts the relay station or the recovery cage together with the remote-controlled submersible to a certain depth underwater, and then the remote-controlled submersible departs from the relay station or recovery cage to carry out operations; when recovering, the remote-controlled submersible first enters the relay station or recovery The cage is docked or fixed, and then the relay station or recovery cage together with the ROV is hoisted to the surface mother ship. [0003] When th...

AI Technical Summary

Problems solved by technology

For example, when the underwater mobile platform needs to carry the remote-controlled submersible in its head space, and deploy and recover the remote-controlled submersible from the back of the underwater mobile platform, it is not appropriate to directly use the relay station to carry the remote-controlled submersible, because the relay station can only Docking with and restraining the ROV from below

In addition, it is not suitable to use the recovery cage to carry the remote control submersible on the underwater mobile platform, because when the remote control vehicle enters the recovery cage, it needs to carefully operate from the side to enter the rectangular space of the recovery cage

When the recovery cage is applied to the underwater mobile platform, it is necessary to set up a special mechanism to extend the recovery cage out of the profile line of the mobile platform in order to complete the deployment and recovery of the remote control submersible. Therefore, the above-mentioned relay station or recovery cage device When the underwater mobile platform is used to carry remote-controlled submersibles, it needs to occupy a large space of the underwater mobile platform, increase the carrying weight on the underwater mobile platform, and also increase the burden of the propulsion power of the underwater mobile platform; and remote-controlled diving The deployment and recovery operations of the device are complex and inefficient
