The invention provides a load rejection method of a load rejection device for underwater equipment and a load rejection system for the underwater equipment, and belongs to the technical field of equipment safety self-rescue. The load rejection method comprises the following steps that when the underwater equipment runs, a load rejection control capacitor in a control unit of the load rejection device is charged through a power supply end, a power-loss electromagnet of the load rejection device is controlled to be powered off, and at the moment, the power-loss electromagnet and a counterweight armature of the load rejection device are magnetically attracted and fixed; when the underwater equipment actively or passively cuts off the power supply of the power supply end, the load rejection control capacitor discharges to the power-losing electromagnet, at the moment, the magnetism of the power-losing electromagnet is counteracted reversely and loses the magnetic attraction force, and the counterweight armature loses the magnetic attraction force and is thrown out. The load rejection system comprises a load rejection device and a control unit. The load rejection control capacitor is a passive element, and the static standby power consumption of the load rejection control capacitor is very low, so that the limited battery electric energy of underwater equipment is saved, and the safe self-rescue problem that a traditional power-losing electromagnet is suddenly powered off due to power supply failure and cannot be controlled to complete load rejection can be solved.
本发明提供一种水下设备用抛载装置的抛载方法及水下设备用抛载系统,属于设备安全自救技术领域。抛载方法包括以下步骤:水下设备运行时,通过电源端向抛载装置的控制单元中的抛载控制电容充电,并控制抛载装置的失电电磁铁断电,此时失电电磁铁与抛载装置的配重衔铁磁吸固定;当水下设备主动或被动断开电源端供电时,抛载控制电容向失电电磁铁放电,此时失电电磁铁的磁性被反向抵消而失去磁吸力,配重衔铁失去磁吸力而抛出。抛载系统包括抛载装置和控制单元。本发明采用的抛载控制电容为无源元件,其静态待机功耗非常低,从而节省了水下设备有限的电池电能,又能克服传统失电电磁铁因供电故障突然断电而不能受控完成抛载的安全自救问题。
