Abstract

The invention discloses an ROV underwater docking and retracting / deploying device which comprises a top plate with holes at the middle, wherein a locking module is mounted between the holes; a telescopic mechanism is mounted at the upper part of the locking module; a cable penetrates in the telescopic mechanism through a sleeve; the cable is connected with ROV; the ROV is positioned below two top plates; a first ear plate is fixed at each of the two ends of the telescopic mechanism respectively; the first ear plate is articulated with a first hydraulic push rod; a chute is formed in the upper surface of the top plate; a slider is mounted in the chute; an opening / closing plate vertical to the top plate is mounted at the outer end of the top plate; the head part of the first hydraulic push rod is connected with the slider; a first connecting rod is articulated between the slider and the opening / closing plate; a second ear plate is fixed at the outer-side middle of the opening / closing plate; the second ear plate is articulated with a second hydraulic push rod; the head part of the second hydraulic push rod is connected with an underlying structure; the underlying structure is mounted at the bottom of the opening / closing plate through a hinge; and the ROV underwater docking and retracting / deploying device also comprises a control module for controlling the first hydraulic push rod and the second hydraulic push rod to work. The ROV underwater docking and retracting / deploying device has low cost and wide applicability.

Description

technical field [0001] The invention relates to the technical field of underwater docking and retracting devices, in particular to an ROV underwater docking and releasing device. Background technique [0002] In deep-sea exploration and research, ROVs are required to perform various operations. For the retraction and deployment of ROVs, the relatively mature and most widely used method is to use surface ships for deployment and recovery: one is to directly lift and retract ROVs through lifting mechanisms. The other is to lift and retract the ROV together with the repeater. However, these two forms are limited by factors such as wind and waves, and put forward more stringent environmental requirements for retractable conditions. For deep-sea operations, underwater retraction can not only shorten the time required for deployment and recovery, but also avoid external disturbances such as wind and waves, improve operational efficiency, and enhance concealment. However, this me...
