Under the condition of the optimal wind direction, a sailing navigation-aid ship using the catrig as the auxiliary power in the United states can save oil by 30 percent and increase the sailing speed by 18 percent. Due to the large size of the sails used, the cost is increased when considering the fixing of the sails, and although the fuel consumption is reduced, the cost of the ship is higher than that of the conventional ship. Meanwhile, due to the variability of wind power and wind direction, the direction of the sail of the ship needs to be adjusted to obtain the maximum wind power during sailing, so that the ship can deviate from a preset route, and the sailing distance and the sailing time are increased. Considering that the sail is mainly used for navigation aid, but the offshore wind direction is variable, it is not easy to always aid navigation, and when the ship sails against the wind, the sail can generate huge resistance and increase oil consumption, and if the sail is folded, the wind power cannot be fully utilized; therefore, when the ship sails against the wind, how to convert huge wind energy into energy beneficial to the ship through the sail enables the sail to assist in navigation and reduce the running cost of the ship, and the difficult problem to be solved is needed.

The mast 4 is fixedly connected with the sail body I1 and the sail body II 2 through double-end studs and nuts; the two ends of the mast 4 are cylinders, the middle of the mast is preferably provided with a square bump, and the convex dice are used for fixing the mast and the rotating shaft, so that the sail does not move, and the stability of the system is improved.
In this embodiment, the rotating shaft 3 is preferably a stepped shaft, and includes a square shaft section and a cylindrical shaft section, the square shaft section is provided with a radial through hole of the square, and the radial through hole of the stepped shaft is matched with the size of the square bump of the mast 4.
The two ends of the square shaft section of the stepped shaft are cylindrical shaft sections, and the cylindrical shaft sections are connected with the support 5 through rolling bearings and fixed through double-end studs and nuts. One side of the stepped shaft is provided with a shaft section with a diameter smaller than that of a cylinder connected with the bracket 5, and the shaft section is used for mounting a coupler and connecting a generator.
The support 5 is arranged on the base, a rolling bearing is arranged between the support and the base, the rolling bearing is fixed through a stud and a nut, and the support can rotate relative to the base.
The inner side of the center of the bottom edge of the bracket 5 is provided with a deep hole for installing the positioning rod 7. The positioning rod 7 is mainly used for fixing the relative position between the sail body and the support in the navigation aid form and realizing the relative rest of the sail body and the support.
The installation position and the conversion method of the invention in two forms of navigation aid and power generation are described below with reference to fig. 7 and 8:
as shown in fig. 7, when the sail is used for assisting in navigation, the sail body I1 and the sail body II 2 face in the same direction, and are fixedly connected with the mast 4 through a stud and a nut; adjusting the sail body II 2 to enable the sail body II 2 and the support 5 to form a deflection angle, placing the positioning rod 7 into a through hole in the back of the sail body II 2, then rotating the sail body II 2 to the original position, and enabling the positioning rod 7 to automatically slide into a deep hole in the support 5, so that the sail body II 2 and the support 5 are fixed.
When the wind direction changes, the position of the support 5 relative to the wind direction is adjusted to enable the sail body to be in an optimal position for generating power by utilizing wind energy, then the stud and the nut on the back of the sail body II 2 are screwed down, the orientation of the sail body II 2 is adjusted to enable the sail body II 2 and the sail body I1 to be in a back direction, and then the stud and the nut are screwed up to enable the sail body II 2 and the sail body I1 to be fixed; then the positioning rod 7 is lifted upwards, so that the positioning rod 7 is separated from the bracket 5, the sail body II 2 is stirred, the sail body II 2 forms a deflection angle with the bracket 5, and then the positioning rod 7 is taken out.
