The invention relates to the technical field of underwater robots, in particular to a power-off load rejection device of an autonomous underwater robot. Comprising a shell, an insulating sleeve, an electromagnetic iron core, a coil and an underwater cable, the insulating sleeve is arranged in the shell, the upper end of the electromagnetic iron core penetrates through the insulating sleeve and the shell and then is locked through a locking nut, the lower end face of the electromagnetic iron core is an adsorption face used for adsorbing a throwing object, and the underwater cable is connected with the coil. The electromagnetic iron core generates a magnetic field to attract the throwing object, and the throwing of the throwing object is realized through the power failure of the coil. A power-down load rejection mode is adopted, the stability of the system is greatly improved, the load rejection state of the ballast is controlled through circuit on-off of the coil, and the purposes of high reliability, rapid response, simple structure and convenient installation are achieved.

    本发明涉及水下机器人技术领域,特别涉及为一种自主式水下机器人的下电抛载装置。包括外壳、绝缘套、电磁铁芯、线圈及水下电缆,其中绝缘套设置于外壳内,电磁铁芯的上端穿过绝缘套及外壳后通过锁紧螺母锁紧,电磁铁芯的下端面为用于吸附抛载物的吸附面,水下电缆与线圈连接,线圈通电后,使电磁铁芯产生磁场吸附抛载物,通过线圈断电来实现抛载物的抛载。本发明采用下电抛载的模式,极大的提高了系统的稳定性,通过线圈的电路通断来控制压载物的抛载状态,达到了可靠性高,响应快速,结构简单,安装方便的目的。
