Problems solved by technology

The disadvantage is that multiple bolts are often required, and it is difficult to ensure that all bolts are disconnected at the same time
In addition, it is necessary to ensure that the wreckage does not damage the surrounding structures and equipment when the bolts are disconnected. If necessary, a protective structure should be installed accordingly, which increases the cost.

Abstract

The invention relates to a load rejection device for underwater equipment, and particularly relates to an electrochemical corrosion type load rejection device for an oceanographic instrument. The load rejection device for the underwater equipment comprises a communication unit, a load rejection control unit and a load rejection movement unit, wherein the communication unit communicates with the load rejection control unit, and the load rejection control unit is connected with the load rejection movement unit respectively through a cathode lead (2) and an anode lead (1). The load rejection device is simple and convenient and easy to operate, and a load rejection weight is only suspended every time before the load rejection device is in use.

Description

technical field [0001] The invention relates to an underwater dumping device, in particular to an electrochemical corrosion type loading dumping device for marine instruments. Background technique [0002] With the development of my country's ocean exploration technology, ocean exploration instruments, especially deep-sea instruments, are more and more widely used in scientific research and investigation. When marine exploration instruments work underwater, due to the complex operating environment, in case of emergency situations such as failure and power failure, in order to ensure that the instrument can be recovered safely, it is necessary to set up a dumping device to dump the heavy objects carried by the instrument so that The instrument uses its own buoyancy to rise to the sea surface. And it can also increase the sinking and floating speed of the marine instrument by dumping the weight, saving the time for underwater operations. [0003] At present, the dumping syst...
