The small underwater glider comprises a pressure-resistant cabin, a rear water immersion cabin, a posture adjusting module, a buoyancy driving module, a front water immersion cabin and a buoyancy compensation device, the front water immersion cabin is arranged at the front end of the pressure-resistant cabin, the buoyancy compensation device is installed in the front water immersion cabin, and the buoyancy compensation device comprises a shell, a piston and a spring; one end of the shell is closed, a water inlet is formed in the other end of the shell, the piston is installed in the shell in a sealed mode to divide the shell into a sealed cavity and a water inlet cavity communicated with the water inlet, the spring is installed in the sealed cavity, and the piston can reciprocate in the length direction of the shell under the action of acting force on the two sides of the piston. According to the underwater glider, the buoyancy compensation device is installed in the front immersion cabin, in the floating and diving process of the underwater glider, the piston reciprocates in the shell under the action of seawater pressure and spring restoring force, the drainage volume of the underwater glider is adjusted, buoyancy compensation of the underwater glider at different depths is achieved, and energy consumption is reduced.
本发明公开了一种具有浮力补偿的小型水下滑翔机,包括耐压舱、后浸水舱、姿态调节模块、浮力驱动模块、前浸水舱和浮力补偿装置,前浸水舱设置在耐压舱的前端,浮力补偿装置安装在前浸水舱内,浮力补偿装置包括壳体、活塞和弹簧,壳体的一端封闭,另一端设有进水口,活塞密封安装在壳体内以将壳体分割为密封腔以及与进水口连通的进水腔,弹簧安装在密封腔内,活塞可在其两侧作用力的作用下沿壳体长度方向往复移动;本申请通过在前浸水舱内安装浮力补偿装置,在水下滑翔机上浮和下潜过程中,活塞在海水压力和弹簧回复力作用下在壳体内往复移动,调节水下滑翔机的排水体积,实现水下滑翔机在不同深度下的浮力补偿,减少能耗。
