Deep sea ballast releasing device

Abstract

The invention provides a deep sea ballast releasing device. The device comprises a bracket, wherein the bracket is provided with an electric solenoid component and a two-stage lever releasing component; the electric solenoid component consists of a deep sea electric solenoid and an electric solenoid plunger; the two-stage lever releasing component consists of a first-stage lever and a second-stage lever; the first-stage lever and the second-stage lever can rotate on a vertical plane around a supporting point on respective bracket; the position of the gravity point of the first-stage lever is restrained by one end of the electric solenoid plunger; the force point of the first-stage lever is the gravity point of the second-stage lever; and the force point of the second-stage lever is a ballast suspension point. The first-stage lever is matched with the second-stage lever to obtain a relatively long resistance arm with a relatively small space, and the release of the ballast is controlled by a small power produced after the electric solenoid is electrified, so that the safety and the reliability are achieved. The device has a simple and compact structure, can be used repeatedly and used in full sea depth, has pressure resistance and corrosion resistance, can be reliably carried and release ballast of 100 kilograms, has short response time and is particularly suitable for releasing the ballasts of underwater robots and deep sea engineering machinery.

Description

technical field [0001] The invention relates to a device for releasing heavy ballast installed on deep-sea operation equipment, and is especially suitable for ballast release of underwater robots and deep-sea engineering machinery. Background technique [0002] Existing devices for underwater dumping mostly use fuses, electric squibs, and balls to release ballast. The methods of fuses and squibs have poor reusability, and parts must be replaced after each use. The ball method has limited load capacity and is difficult to use in deep sea due to sealing problems, and its reliability is difficult to guarantee for heavier ballast release. The underwater dumping device is necessary for underwater operation equipment, and its reliability and economy need to be satisfied.
