The invention discloses a load rejection device for an underwater unmanned vehicle. The load rejection device comprises a main mounting plate, a load rejection executing mechanism, a load rejection block, a spring and a load rejection block cover, the load rejection executing mechanism and the load rejection block cover are mounted on the main mounting plate; a load rejection block and a spring are mounted in the load rejection block cover; the spring is located between the load rejection block and the load rejection block cover, and one end of the spring is fixedly connected with the load rejection block cover; when the load rejection executing mechanism is locked, the load rejection executing mechanism compresses the load rejection block, the load rejection block is restrained in the load rejection block cover, and the spring is in a compressed state; after the load rejection executing mechanism is unlocked, pressing constraint on the load rejection block is released, and the load rejection block falls off from the interior of the load rejection block cover under the combined action of gravity and the spring. According to the load rejection device of the unmanned underwater vehicle, the lever principle is utilized, the electromagnet with small attraction force can be used for fixing and throwing away the load rejection block with large weight, and energy loss is small.

    本发明公开了一种水下无人航行器抛载装置,包括:主安装板、抛载执行机构、抛载块、弹簧和抛载块罩;抛载执行机构和抛载块罩安装在主安装板上;抛载块罩内部安装有抛载块和弹簧;弹簧位于在抛载块与抛载块罩之间,且弹簧一端与抛载块罩固联;抛载执行机构锁定时,抛载执行机构压紧抛载块,将抛载块约束在抛载块罩内,弹簧处于压紧状态;抛载执行机构解锁后,释放对抛载块的压紧约束,抛载块在重力和弹簧的联合作用从抛载块罩内脱落。本发明所述的水下无人航行器抛载装置,利用杠杆原理,使用较小吸力的电磁铁即可实现重量较大的抛载块的固定和抛离,能量损耗较小。
