Abstract

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.

Description

technical field [0001] The invention relates to a propulsion device for ships, in particular to a paddle propulsion device for ships. Background technique [0002] With the integration of the global economy, the global shipping business has greatly increased, and currently the cost of shipping business fuel accounts for about 50%. Whoever reduces the cost of fuel will be more competitive in the market. The market is invincible. At present, most marine propellers on the market are generally propeller devices. When the propeller rotates to push the water flow, the speed at the edge is much greater than the speed at the center of the propeller. The thrust is mainly generated near the edge, and the utilization rate of the blade area is low. Under the premise of the same blade area, the rotational speed of the propeller blade is inversely proportional to the stroke efficiency of the propeller. To produce the same thrust and improve the stroke efficiency, it is necessary to incr...
