The invention discloses a marine paddle type propeller device. The marine paddle type propeller device comprises two layers of parallel supports, chain wheels, chains, a power device and a propelling force control mechanism (further comprises a plurality of propelling mechanisms and two propelling direction control devices). Each propelling mechanism comprises a blade, a blade rotating shaft, two bearings and a set of blade limiting wheels, wherein the two bearings are fixed to all the layers of chains respectively, the blade is fixed to the blade rotating shaft, the blade limiting wheels are fixed to the blade rotating shaft through connecting rods, and the blade limiting wheels are located on the two sides of the blade respectively. The propelling direction control device comprises two parallel linear limiting chutes, and the blade limiting wheels slide in the motion direction of the chains with one linear limiting chute serving as a rail. The problems that an existing marine propeller is low in paddling efficiency and high in energy consumption cost can be solved through the marine paddle type propeller device.
