The invention discloses a buoyancy adjusting device for a large-depth underwater glider, and belongs to the field of underwater vehicles. The device comprises a hydraulic control module, an oil bag, a piston type oil tank and a pressure-resistant shell, wherein the oil bag is communicated with the piston type oil tank through the hydraulic control module; a high-pressure plunger pump, a hydraulic valve and a cartridge filter of the hydraulic control module are all mounted on a hydraulic valve block; the hydraulic valve comprises a two-position two-way valve, a three-position four-way valve, an overflow valve and a one-way valve; one side wall of the hydraulic valve block is mounted on the inner wall of the watertight end cover, and a plurality of oil duct holes which are communicated with one another are formed in the valve block body, so that communication of all parts is realized, and an oil duct loop is formed; one oil port on the hydraulic valve block is hermetically connected with the oil port of the watertight end cover, and the other oil port is hermetically connected with the piston type oil tank; and the motor is mounted on the high-pressure plunger pump. Hydraulic oil is controlled to flow from the oil tank to the oil bag or from the oil bag to the oil tank by opening and closing the hydraulic valves on the hydraulic valve block, so the volume of the oil bag is changed, and the buoyancy borne by the underwater vehicle is changed accordingly.

    本发明一种大深度水下滑翔机浮力调节装置,属于水下航行器领域;包括液压控制模块、油囊、活塞式油箱和耐压壳体,通过液压控制模块连通油囊与活塞式油箱;液压控制模块的高压柱塞泵、液压阀和插装滤器均安装于液压阀块上;液压阀包括二位二通阀,三位四通阀,溢流阀和单向阀;液压阀块的一侧壁安装于水密端盖内壁上,其阀块体内开有多个相互连通的油道孔,实现各部件的连通,构成油道回路;液压阀块上一个油口与水密端盖的油口密封连接,另一个油口与活塞式油箱密封连接;电机安装于高压柱塞泵上。通过液压阀块上各液压阀的开闭,控制液压油从油箱流向油囊或从油囊流向油箱内,实现油囊的体积改变,从而使水下航行器所受的浮力大小随之改变。
