Embodiment Construction

[0025] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0026] See attached figure 1 , an underwater winch that can independently realize the retraction and release of communication buoys, which includes: a watertight motor 1, a worm gear installed in the first sealed box 2, an electromagnetic clutch 4 installed in the second sealed box 5, and a drum winch 6. Stroke detection device 9, electric slip ring 10, buoy retractable controller 12 and buoy guide cylinder 13;

[0027] The second sealed box body 5 and the reel winch 6 are installed on the winch support 3; the winch support 3 is the installation base of the whole winch, plays the role of support and fixing, and it is connected with the underwater vehicle by four screws; watertight Motor 1, worm and gear, electromagnetic clutch 4, reel capstan 6 are executive mechanism of the present invention;

[0028] The first sealed box 2 is sealed and connected with ...

Abstract

The invention discloses an underwater winch which can independently realize the retraction and deployment of a communication buoy. When it is necessary to communicate with the outside world, the buoy retracting controller sends a command to release the buoy, the electromagnetic clutch changes from the engaged state to the released state, the drum winch is separated from the worm gear, and the communication buoy pulls the drum winch to rotate under the action of its own positive buoyancy , to realize its own release. After the communication is completed, the buoy retracting and releasing controller sends a buoy retracting command, the electromagnetic clutch changes from the released state to the engaged state, the drum winch is connected to the worm gear and worm sealed box, and the watertight motor is started, and the watertight motor drives the drum winch to rotate through the worm gear and worm. Realize the recovery of communication buoys. When the communication buoy is recovered in place, the stroke detection mechanism is touched, and the watertight motor is powered off. At this time, the communication buoy is fixed in place by the self-locking function of the worm gear, and will not be accidentally pulled out. The invention can independently realize the complete process of retracting and releasing the communication buoy.

Description

technical field [0001] The invention relates to the technical field of underwater self-retracting and retracting, in particular to an underwater winch for realizing the retracting and retracting of communication buoys. Background technique [0002] Autonomous underwater vehicles are an important branch of underwater unmanned vehicles. Because it gets rid of the shackles of tethers and is more flexible in underwater operations and operations, this technology is increasingly valued by the military, marine and other technical departments of developed countries. [0003] Communication between autonomous underwater vehicles and the ground is an integral part. For reasons of safety, concealment, and communication reliability, it is an important research direction for the autonomous underwater vehicle to actively release the communication buoy and recover the buoy to the autonomous underwater vehicle after the communication is completed. . It is a common way to use a winch to re...
