The invention discloses an underwater multi-stage load rejection device, relates to the technical field of underwater systems or equipment, and solves the problems that an existing load rejection device is low in reliability and stability, single load rejection cannot meet task requirements, and a multi-stage load rejection release mechanism occupies a large space. The multiple stages of load rejection sections are sequentially from the Nth stage to the first stage from inside to outside and/or from top to bottom, and are assembled below the load rejection release mechanism in sequence; the load rejection releasing mechanism is composed of a load rejection fixing frame, a driving motor, a crank sliding block structure and plug pin rods, the driving motor is installed on the load rejection fixing frame, the Nth-stage load rejection section to the first-stage load rejection section are sequentially hung on the plug pin rods from inside to outside through the corresponding stages of hanging lugs, the two plug pin rods are driven by the driving motor to synchronously pull to slide, and the load rejection section and the first-stage load rejection section are sequentially hung on the plug pin rods from inside to outside. The equipment can realize a multi-stage operation mode of firstly suspending and then floating, and is small in occupied space and high in reliability.

    本发明公开了一种水下多级抛载装置,涉及水下系统或装备的技术领域,解决了目前抛载装置可靠性、稳定性低,单次抛载无法满足任务需求,多级抛载释放机构占用空间大的问题,本发明的技术要点包括:抛载释放机构和多级抛载段,多级抛载段由内至外和/或由上至下依次为第N级至第一级抛载段,并按顺序装配在抛载释放机构的下方;抛载释放机构由抛载固定架、驱动电机、曲柄滑块结构和插销杆组成,驱动电机安装在抛载固定架上,从第N级到第一级抛载段通过对应的各级挂耳由内至外依次挂在插销杆上,通过驱动电机驱动,同步拉动两个插销杆滑动,对第一级至第N级抛载段依次进行释放,该设备能够实现先悬浮再上浮的多级作业模式,占用空间小,可靠性高。
