Underwater glider power distribution device

The utility model discloses an underwater glider power distribution device comprising a power distribution power supply. The power distribution power supply is connected with low-voltage pre-warning circuits. The low-voltage pre-warning circuits adopt a voltage comparison chip to compare the output voltage of the power distribution power supply with a reference voltage, generate low-voltage pre-warning signals, and output the low-voltage pre-warning signals through isolation circuits. The underwater glider power distribution device is designed through overall consideration based on an existing machine body design method. The underwater glider power distribution device has an under-voltage isolation alarm function of the power distribution power supply. A low-power-consumption voltage regulation chip and low-power-consumption optical coupling devices are chosen. The power consumption can be controlled below 20muA, and the power supply efficiency is not lower than 90%.
