Fuse-type load rejection device for underwater equipment and control method thereof

Abstract

The invention relates to a fuse-type load rejection device for underwater equipment and a control method thereof. The device comprises a fuse-type load rejection device control unit in an underwater equipment bay and a load rejection device sealing connecting piece outside the equipment bay, wherein the load rejection device control unit and the load rejection device sealing connecting piece are electrically connected by a conducting wire; the load rejection device sealing connecting piece is provided with a first terminal, a second terminal, insulating sealing fillers, a first low-resistance connection pin, a second low-resistance connection pin and an alloy resistance wire, wherein the first low-resistance connection pin and the second low-resistance connection pin penetrate through a cavity body of a sealing fixing piece; one ends of the low-resistance connection pins are respectively and electrically connected with the terminals which are arranged at the end part of the sealing fixing piece, and the other ends pass through a short circuit arranged outside the sealing fixing piece; the cavity body of the sealing fixing piece is filled with the insulating sealing fillers; and the alloy resistance wire is connected with a ballast weight by a high-strength nonmetal connecting line. The device of the invention does not have any movement mechanism or movement in a load rejection process, is not corroded by seawater or affected by biological contaminants, and has the advantages of low working voltage, safety, reliability and flexible quality of the ballast weight.

Description

technical field [0001] The invention relates to underwater load dumping technology, in particular to a fusing type load dumping device for underwater equipment and a control method thereof. Background technique [0002] With the deepening and development of robot research, its application is becoming more and more extensive, and there are underwater equipment such as underwater robots that can replace humans in various dangerous operations underwater. In order to improve the safety of underwater equipment, it is usually equipped with an emergency dumping device. When an emergency occurs in the underwater equipment, trigger the throwing device to throw off the ballast weight, so that the underwater equipment is in a positive buoyancy state, safely surfaced, and waits for the recovery of the surface ship. At present, the common ways of dumping underwater equipment are as follows: [0003] Electromagnetic device dumping: usually using an electromagnet or a energized coil as a...

AI Technical Summary

Problems solved by technology

This device is suitable for the release of super-mass ballast heavy objects ranging from hundreds of kilograms to hundreds of tons. It has high cost and large explosion impact, and is not suitable for small-weight underwater equipment such as underwater robots.

[0005] In order to further improve the stability, safety, low power consumption, modularization and other performances of the underwater equipment dumping device, it is necessary to further develop a new type of underwater dumping device , and the dumping device for underwater equipment that meets the above requirements has not been reported yet.
