The invention relates to support equipment of an underwater robot, in particular to an underwater robot buoyancy adjusting device, comprising a carrier shell, end covers, an inner leather barrel, an outer leather barrel, a direct current motor, a gear pump and a valve group, wherein two ends of the carrier shell are connected with the end covers to jointly define a sealed cabin in which the inner leather barrel, the direct current motor, the gear pump and the valve group are arranged; the gear pump is driven to work by the direct current motor; an oil outlet of the gear pump is in series connection with a check valve and a filter and then connected to the valve group; an oil suction port of the gear pump is in direct connection with the valve group through a pipeline; oil ports of the inner leather barrel and the outer leather barrel are connected with the valve group through the pipeline. The size of the outer leather barrel is increased as oil is injected into the outer leather barrel through the gear pump, and buoyancy is increased; hydraulic oil in the outer leather barrel flows to the inner leather barrel through water pressure or oil suction by the gear pump, the size of the outer leather barrel is decreased and the buoyancy is decreased. The underwater robot buoyancy adjusting device is simple and reliable and independent in functions, can be applied to an underwater robot as an independent module, and has advantages of small power, low energy consumption, low noise and the like.
