Low-power underwater load rejection device

Abstract

The invention discloses a low-power underwater load rejection device which comprises a motor, a watertight barrel, a permanent magnet, an iron load rejection block, a connecting flange, a load rejection mechanism cover plate, a watertight joint fixing piece and a pressure-resistant wet-plug connector male head; the load rejection mechanism cover plate is fixedly sealedly connected with the watertight barrel; the motor is mounted in the watertight barrel; the upper end of the motor is electrically connected with a binding post of the end part of the pressure-resistant wet-plug connector male head; the connecting flange is fixed on the rotating shaft of the motor; the permanent magnet is fixed at the lower side of the connecting flange; a position, relative to the permanent magnet, of the bottom end of the watertight barrel is provided with a circular slot; a small part of the iron load rejection block is embedded into the circular slot and is inserted into or divorced from the slot according to the conditions; the circular slot plays a guiding role, to prevent the iron load rejection block from deviating the circular slot under the suction action of the permanent magnet when the permanent magnet is displaced under the action of the motor. The device can smoothly discard ballast, has low power consumption and easy and quick ballast installation process, and ensures that an underwater aircraft can form positive buoyancy and can be normally recovered to the water surface.

Description

technical field [0001] The invention relates to a load dumping device, in particular to a low power consumption underwater load dumping device. Background technique [0002] In order to improve the safety of underwater vehicles, emergency dumping devices are usually equipped. When the underwater vehicle is in an emergency, the dumping device is triggered 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] (1) Electromagnetic device dumping: Usually, an electromagnet or a energized coil is used as a power component. When the electromagnet or energized coil is energized, a magnetic field is generated to hook the ballast weight on the underwater equipment; when the power is cut off, the ballast weight is removed. throw it away. The disadvantage of this device is that it is large in...

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] (3) Some underwater ejectors use electrochemical methods, which have certain pollution to the ocean, but are difficult to use in fresh water;

[0006] 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, but the underwater dumping device that meets the above requirements has not been reported yet.
