Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] The optical fiber passive cable-releasing buoy release mechanism provided by the present invention is generally installed on the relay station system of the remotely controlled submersible, and is used for the relay station to release cylindrical equipment underwater, such as the optical fiber passive cable-releasing buoy.

[0039] Optionally, the buoy release mechanism of the passive cable-releasing buoy is installed on the relay station of the ROV through bolts.

[0040] When the remotely controlled submersible is separated from the relay station system, the optical fiber passive cable release buoy clamped on the optical fiber passive cable release buoy release mechanism is released synchronously, and the fine optical fiber is ...

Abstract

The invention discloses an optical fiber passive cable-laying buoy release mechanism, and belongs to the field of remotely operated underwater vehicles. The mechanism includes a double-acting thrust hydraulic cylinder, a base and two sets of clamping components. The two sets of clamping components are fixed on the base, the first clamping component includes a wide circular claw and a wide circularclaw tension spring, the second clamping component includes a narrow circular claw and a narrow circular claw tension spring. The wide circular claw and the narrow circular claw are crossed and connected in series to form a scissors-like structure. When the optical fiber passive cable-laying buoy release mechanism is in a clamping state, the inner diameter of a circular profile formed by the widecircular claw and the narrow circular claw is same as the outer diameter of an optical fiber passive cable-laying buoy; when the optical fiber passive cable-laying buoy release mechanism is in a release condition, the inner diameter of a circular profile formed by the wide circular claw and the narrow circular claw is larger than the outer diameter of the optical fiber passive cable-laying buoy.The problem that it can not be ensured that the optical fiber passive cable-laying buoy can be released in time is solved, the optical fiber passive cable-laying buoy can be released in time, and thesafe descending effect of the remotely operated underwater vehicles is ensured.

Description

technical field [0001] The embodiment of the present invention relates to the field of remotely controlled submersibles, in particular to a buoy release mechanism for passive optical fiber cable laying. Background technique [0002] The remote-controlled submersible is an intelligent robot widely used in underwater operations. The remote-controlled submersible is connected to the deck control room or control unit on the mother ship through an umbilical cable. For remote-controlled submersibles with large depths, when using this traditional method, an extremely long armored umbilical cable is required to operate, which puts forward high technical requirements for both the surface deployment device and the armored umbilical cable, and increases the system capacity. difficulty. [0003] At present, the commonly used method is to add a relay station system between the mother ship and the remote-controlled submersible. The mother ship and the relay station are connected by an ar...
