Marine oil hose reel

Abstract

Disclosed is a marine oil hose reel, including a mounting frame, a reel, a hose, an oil pump assembly and a driving assembly. The reel is rotatably mounted on the mounting frame. The hose is wound around the periphery of the reel. The oil pump assembly is arranged on the mounting frame and provided with a first port communicated with an oil depot and a second port connected to an end of the hose. The driving assembly is arranged on the mounting frame and provided with two driving parts spaced apart, one of the driving parts is connected to the reel to drive the reel to rotate, and the other one is connected to the oil pump assembly to drive the oil pump assembly to pump oil. The integrated structural design of the present disclosure allows for integration of the reel and an oil pump device, reducing the occupied space.
