The invention discloses a trim buoyancy adjusting device, and belongs to the technical field of underwater vehicle structure design. The device comprises an oil pump unit, a spring piston low-pressure compensator, an electrical controller, an oil cylinder control hydraulic valve group, a double-acting seawater piston cylinder and a seawater flow distribution valve group, wherein the oil pump unit and the spring piston low-pressure compensator are mounted in a closed oil tank; the trim buoyancy adjusting device is installed outside a cabin of the aircraft and placed in seawater or in a pressure-bearing cabin. When the aircraft enters water, the oil pump unit controls the hydraulic valve group through the oil cylinder to drive the double-acting seawater piston cylinder, then seawater is injected into the pressure-bearing water tank through the seawater flow distribution valve group, or seawater in the pressure-bearing water tank is discharged out of the tank, and buoyancy adjustment of the aircraft is achieved. When the trim buoyancy adjusting device is connected with the stern pressure-bearing water tank and the bow pressure-bearing water tank of the aircraft, the trim buoyancy adjusting device allocates seawater between the stern pressure-bearing water tank and the bow pressure-bearing water tank or outside the outboard, and therefore trim adjustment of the aircraft is achieved.
本发明公开了一种纵倾浮力调节装置,属于水下航行器结构设计技术领域,装置包括安装在封闭油箱内的油泵机组和弹簧活塞低压补偿器以及安装在设备电气承压舱内的电气控制器、油缸控制液压阀组、双作用海水活塞缸和海水配流分配阀组,纵倾浮力调节装置安装在航行器的舱外置入海水中或承压的舱室内;航行器下水时,油泵机组通过油缸控制液压阀组驱动双作用海水活塞缸,再通过海水配流分配阀组将海水注入承压水舱,或将承压水舱的海水排除到舱外,实现航行器的浮力调节;当纵倾浮力调节装置连接航行器的艉承压水舱和艏承压水舱时,纵倾浮力调节装置将海水在艉承压水舱和艏承压水舱之间或舷外进行调配,从而实现航行器纵倾的调节。
