[0035] The bulk carrier with wind energy auxiliary propulsion device of the present invention has a working principle. When the bulk carrier is sailing on the sea, when strong wind occurs, the wind blows the fan blades 4 to rotate, so that the fan blades 4 drive the driving shaft 3 to rotate, and then the driving shaft 3 drives the transmission worm 5 to rotate through the transmission of the primary driving pulley 6, the primary driven pulley 7 and the primary transmission belt 8, and the transmission worm 5 drives the transmission rod 10 to rotate through the meshing with the primary transmission worm wheel 11, and the transmission rod 10 drives the transmission shaft 13 to rotate through the meshing of the worm shaft section 12 and the secondary transmission worm wheel 14, so that the transmission shaft 13 drives the power-assisting shaft 16 to rotate through the transmission of the secondary driving pulley 18, the secondary driven pulley 19 and the secondary transmission belt 20, and then the power-assisting shaft 16 drives the propeller 21 to rotate, so that the wind energy can be utilized through the fan blades 4, and after the transmission, the propeller 21 is rotated, and the propeller 21 is driven to rotate. The rotation of the paddle 21 assists in the navigation of the bulk carrier and provides additional power for the navigation of the bulk carrier. During the power transmission process, the size of the first-stage active pulley 6 is larger than the size of the first-stage driven pulley 7, so that the rotation speed of the transmission worm 5 is greater than the rotation speed of the drive shaft 3, and the rotation speed of the transmission rod 10 is greater than the rotation speed of the drive shaft 3. Because the size of the second-stage active pulley 18 is larger than the size of the second-stage driven pulley 19, the rotation speed of the power-assisting shaft 16 is greater than the rotation speed of the transmission shaft 13, so that the rotation speed of the propeller 21 is greater than the rotation speed of the fan blades 4, so that when the fan blades 4 rotate, they drive the propeller 21 to rotate faster, and the canvas 23 can catch the wind, further playing a role in promoting the movement of the hull. When the canvas 23 is damaged, the knob bolt 26 can be unscrewed, and then the U-shaped rod 24 can be lifted out of the U-shaped slot 25, and the U-shaped rod 24 can be removed so that the canvas 23 can be replaced in the future.

[0036] The installation method, connection method or setting method of the bulk carrier with a wind-assisted propulsion device of the present invention are all common mechanical methods, and can be implemented as long as they can achieve their beneficial effects; the fan blades and propellers of the bulk carrier with a wind-assisted propulsion device of the present invention are purchased on the market, and technicians in the industry only need to install and operate them according to the accompanying instruction manual.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
