The invention discloses a variable-buoyancy driving device and method for a long-distance underwater glider. The variable-buoyancy driving device comprises an inner oil tank, a primary booster pump, a filter, a high-pressure plunger pump, a one-way valve, an outer leather bag, an electromagnetic valve, an overflow valve and an energy accumulator, the outer leather bag, the one-way valve, the high-pressure plunger pump, the primary booster pump and the inner oil tank are connected in series, and the overflow valve is connected to the primary booster pump; a filter is installed at the air inlet of the high-pressure plunger pump; the outer housing material of the energy accumulator is carbon fiber; according to the variable-buoyancy driving device of the long-distance underwater glider, sufficient power is provided for the long-distance underwater glider through the change of the volume of the outer leather bag, the variable-buoyancy driving device is connected to the primary booster pump through the overflow valve, the filter is connected to the high-pressure plunger pump, the device volume is reduced, and flow channel loss is reduced. And an energy accumulator shell is made of carbon fibers, and an inlet valve and an outlet valve of the high-pressure plunger pump are subjected to hard sealing through steel balls, so that the mass and the volume of the device are reduced, and better power is achieved.

    本发明公开了一种长距离水下滑翔机变浮力驱动装置及其方法,包括内油箱、初级增压泵、过滤器、高压柱塞泵、单向阀、外皮囊、电磁阀、溢流阀、蓄能器,外皮囊、单向阀、高压柱塞泵、初级增压泵、内油箱串联连接,溢流阀连接在初级增压泵上,高压柱塞泵入油口处安装有过滤器,蓄能器外部壳体材料为碳纤维,该长距离水下滑翔机变浮力驱动装置,通过外皮囊体积变化,为长距离水下滑翔机提供充足的动力,通过溢流阀连接在初级增压泵上,过滤器连接在高压柱塞泵上,减小装置体积和量,又减少流道损失,通过蓄能器壳体设置为碳纤维,高压柱塞泵进出阀采用钢球硬密封,降低了装置的质量和体积,从而有更好的动力。
