The invention provides a negative buoyancy compensation device applied to an unmanned underwater vehicle. The negative buoyancy compensation device can quickly perform negative buoyancy compensation on the vehicle. The negative buoyancy compensation device comprises a buoyancy compensation water tank, a linear motor, an upper push rod, a lower push rod, an upper sealing plug and a lower sealing plug. Two ends of a motor shaft of the linear motor are coaxially connected with the upper push rod and the lower push rod respectively; the upper sealing plug is arranged at the upper end of the upperpush rod, and a through hole matched with the upper sealing plug is formed in the upper end of the buoyancy compensation water tank; the lower sealing plug is arranged at the lower end of the lower push rod; a through hole matched with the lower sealing plug is formed in the lower end of the buoyancy compensation water tank; when the linear motor drives the upper push rod and the lower push rod tomove upwards, the upper sealing plug extends out of the buoyancy compensation water tank, and meanwhile, the lower sealing plug moves upwards into the buoyancy compensation water tank, the two through holes are opened; when the linear motor drives the upper push rod and the lower push rod to move downwards, the upper sealing plug and the lower sealing plug are matched with the corresponding through holes at the same time, and the buoyancy compensation water tank is sealed.

    本发明提供一种应用于水下无人航行器的负浮力补偿装置,能够快速的对航行器进行负浮力补偿。该负浮力补偿装置包括:浮力补偿水舱、直线电机、上推杆、下推杆、上密封堵头和下密封堵头;其中直线电机电机轴的两端分别同轴连接上推杆和下推杆;上推杆的上端设置有上密封堵头,浮力补偿水舱上端设置有与上密封堵头配合的通孔;下推杆的下端设置有下密封堵头,浮力补偿水舱下端设置有与下密封堵头配合的通孔;当直线电机带动上推杆和下推杆上移,使上密封堵头伸出浮力补偿水舱,同时使下密封堵头上移至浮力补偿水舱内部时,两个通孔打开;当直线电机带动上推杆和下推杆下移,使上密封堵头和下密封堵头同时和对应的通孔配合时,密封浮力补偿水舱。
