A large slender ratio load system for underwater deployment and recovery of a manned submersible

Abstract

A manned submersible deploying and recovering a large slenderness load system under water, comprising a manned submersible and a manned cabin, the manned submersible outside the manned cabin is respectively equipped with a hydraulic source, a winch, an auxiliary mechanism and a water The power supply is lowered, and a control box is installed inside the manned cabin; the winch is connected with a claw through a load-bearing umbilical cable; the auxiliary mechanism includes multi-stage hydraulic cylinders arranged at intervals, and the top of each multi-stage hydraulic cylinder passes through the first hinge seat Hinged to the outside of the manned submersible, the head of the piston rod of each multi-stage hydraulic cylinder is hinged with a long strip bracket through the second hinge seat, and the two strip brackets are arranged in parallel and spaced apart. A small motor is fixed, and the output end of the small motor is connected to a pinion. A semicircular rotating bracket is installed between the two long strip brackets. The outer peripheral surface of the rotating bracket is provided with an arc-shaped rack and pinion. Engaging with the rack, the load is placed in the swivel bracket. Works reliably.

Description

technical field [0001] The invention relates to the technical field of deploying and recovering devices, in particular to a large slender ratio load system for underwater deploying and recovering a manned submersible. Background technique [0002] With the continuous expansion of seabed exploration, marine energy development, and marine security, the scale of underwater construction and facility installation is increasing. However, the deployment and recovery operations of traditional surface ships are greatly affected by sea wind and waves, and the operation time is limited. It is subject to certain restrictions, and with the increase of deployment and recovery depth, the system is more affected by the gradient flow, and the load will move with the water flow, so it is difficult to achieve precise deployment. During recovery, due to the influence of wind, waves and currents, it is difficult to be accurate. Grab the subsea load. At the same time, the path of surface ships n...

AI Technical Summary

Problems solved by technology

[0002] With the continuous expansion of seabed exploration, marine energy development, and marine security, the scale of underwater construction and facility installation is increasing. However, the deployment and recovery operations of traditional surface ships are greatly affected by sea wind and waves, and the operation time is limited. It is subject to certain restrictions, and with the increase of deployment and recovery depth, the system is more affected by the gradient flow, and the load will move with the water flow, so it is difficult to achieve precise deployment. During recovery, due to the influence of wind, waves and currents, it is difficult to be accurate. Grabbing Subsea Loads

At the same time, the path of surface ships navigating on the water is easy to be detected and recorded. If the payload is deployed and recovered in the field of national defense security, there will be a huge security risk

In addition, the stability of large slender ratio load deployment and recovery is worse, and it is more susceptible to environmental influences, and the difficulty of deployment and recovery is increased due to the large slender ratio of external dimensions.
