Description

Release device for underwater vehicle Technical Field The invention relates to the field of underwater vehicles, in particular to an underwater vehicle releasing device. Background Currently, underwater equipment presents a diversity of developments, and deployment of weapons or monitoring equipment in the vicinity of enemy waters or vessels with unmanned underwater vehicles has become an important direction of research in many countries. In concealed deployment of weapons or monitoring equipment, various release devices are often used. Currently, the release device commonly employs an explosive bolt or a mechanical release mechanism. The explosion bolt release device is characterized in that the connecting part is damaged by igniting a detonator in the explosion bolt, so that the aim of effective release is fulfilled. The mechanical release mechanism is driven by adopting shrinkage or extension of an electromagnet mandrel as driving, the electromagnet drives the mandrel to act through electromagnetic force generated by a coil, the driving force is required to be larger along with the increase of the separating force of a separating device, the volume requirement of the electromagnet is larger, the electromagnet cannot be driven as the mechanical release mechanism at all, the electromagnet is easy to be driven by electromagnetic interference, and the electromagnet is easy to lose efficacy in an enemy electromagnetic interference environment, so that the aim of arranging weapons or monitoring equipment is not realized.
