The invention relates to a matched device of an autonomous underwater vehicle, in particular to a one-way buoyancy regulation device used for the autonomous underwater vehicle. The one-way buoyancy regulation device comprises a buoyancy material outer cover, an outer leather bag cabin, leather bags, a control cabin pressure-resistant shell, a control valve, a pressure-resistant cabin side end cover and a pressure-resistant cabin shell. The outer leather bag cabin, the control cabin pressure-resistant shell, the pressure-resistant cabin side end cover and the pressure-resistant cabin shell are sequentially connected and wrapped by the buoyancy material outer cover. The leather bags are arranged in the outer leather bag cabin and the pressure-resistance cabin shell respectively. A water passing hole is formed in the outer leather bag cabin. A control valve is installed in the control cabin pressure-resistant shell and communicated with the two leather bags. The control valve controls the oil flowing direction between the two leather bags through the autonomous underwater vehicle. The oil in the leather bag in the outer leather bag cabin flows into the leather bag in the pressure-resistant cabin shell. The buoyancy is regulated according to the changes of the size of the leather bag in the outer leather bag cabin. Trimming can be conducted through one-time submerging, and the optimized trimming of the heavy buoyancy can be achieved without conducting extra trimming operation.
