Description

An acoustic release device based on an unsealed underwater electromagnet

Technical field

The utility model belongs to the field of marine equipment and engineering application, and relates to an acoustic release device based on an unsealed underwater electromagnet, which is suitable for sea search, rescue, salvage and recovery of sea test equipment.

Background technique

At present, the manufacturing technology of foreign acoustic release devices has matured. As far as the separation and release methods of the acoustic release device are concerned, there are three methods commonly used abroad. The first is the rotary release method driven by the motor, which has two disadvantages: one is that the motor control is more complicated; the other is that the sealing (dynamic sealing) part during the movement of the motor rotating shaft has always been the core technology. Technology depends on materials and processing technology, and is related to performance such as release load, maximum working water depth, and reliability. The second is the pneumatic separation and release method that uses high-pressure gas to drive the pin movement. The disadvantage is that the pneumatic source needs to be replaced before each use, and the sealed cabin needs to be opened, which brings hidden dangers to watertightness. The third type is the separation type of burning wire, and its disadvantage is that the fuse time of the connecting wire is long (generally 20-60 minutes), which is affected by seawater temperature, salinity, seabed water quality, depth of seabed mud, installation position, material of fuse wire, and processing of fuse wire. Factors such as craftsmanship have a great influence, and the success rate is not high. In addition, the cost of the acoustic release device adopting the above three release methods is high, and the whole is bulky. The separation and release methods of the acoustic release devices manufactured in my country are mostly similar to those of foreign countries, and the reliability is not high. Therefore, most of the acoustic release devices used in my country rely on imports and are expensive.
