[0009] By adopting the above technical solution, the bracket is rotated as a whole until the wind energy rotating axis is perpendicular to the incoming wind direction, and the wind energy is used to blow the blades of the fan blade assembly, so that the blades drive the wind energy rotating axis to rotate, and under the meshing action of the first bevel gear and the second bevel gear, the eccentric shaft is driven to rotate, and under the meshing action of the inner gear and the middle gear, the eccentric shaft drives the middle gear to rotate, and under the meshing action of the middle gear and the outer gear, the outer gear drives the transmission shaft to rotate, and under the meshing action of the third bevel gear and the fourth bevel gear, the transmission shaft drives the drive shaft to rotate, so that the drive shaft drives the auxiliary propeller to rotate, and pushes the bulk carrier to move, so as to realize the use of wind energy during navigation to assist the bulk carrier to sail, reduce the power consumption of the main propeller, save energy and protect the environment, and effectively improve the endurance of the bulk carrier. Among them, the bracket is integrally positioned and rotatably installed on the hull, so that the horizontal direction of the wind energy rotating axis can be adjusted according to the wind direction, so as to make full use of wind energy and reduce the wind resistance of the blades.

[0010] Furthermore, the bracket includes a vertically arranged central axis, a support is provided at the lower end of the central axis, and a frame body arranged on the hull is provided below the support; the lower end of the central axis is positioned and rotatably installed on the support and is connected to a deflection motor for driving its rotation, and the deflection motor is installed on the frame body; the side wall of the support is provided with an eccentric plate arranged along the length direction of the wind energy rotating axis, and the eccentric shaft is positioned and rotatably installed at the end of the eccentric plate away from the support; a wind direction sensor is provided on the bracket, and the wind direction sensor is connected to the deflection motor for communication and control.

[0011] By adopting the above technical solution, the support, frame, eccentric plate, etc. realize the positioning and rotating installation of the central axis around its axis, the positioning and rotating installation of the eccentric axis around its axis, and the eccentric installation relative to the axis of the central axis.

[0012] Furthermore, a mounting ring coaxially arranged with the wind energy rotating shaft is provided at the upper end of the central shaft, the wind energy rotating shaft is positioned and rotatably mounted in the mounting ring, and the mounting ring is located between the two sets of fan blade assemblies.

[0013] By adopting the above technical solution, the wind energy rotating shaft is positioned and rotatably installed on the central shaft using the mounting ring, and the stability of the rotation of the wind energy rotating shaft is ensured, thereby preventing the wind energy rotating shaft from deviating and shaking after working for a long time.

[0017] By adopting the above technical scheme, the limit block is slidably installed in the limit ring groove. When the bracket is positioned and rotated to drive the eccentric shaft to rotate eccentrically, the limit block slides along the circumference of the limit ring groove to limit the eccentric rotation of the eccentric shaft and ensure the stability of the eccentric shaft during rotation. During the positioning and rotation of the eccentric shaft, the installation of the eccentric shaft on the bracket is coordinated to ensure the stability of the eccentric shaft during positioning and rotation, thereby avoiding the eccentric shaft from bending and deformation due to uneven force, and ensuring the accurate meshing of the first bevel gear and the second bevel gear, the internal gear and the intermediate gear.

Among them, the guide ring groove guides the eccentric rotation of the eccentric shaft to avoid interference with the eccentric rotation of the eccentric shaft.

[0020] Furthermore, a plurality of first elastic protective members are arranged in a circumferential array on the outer wall of the ring plate, and a plurality of second elastic protective members are arranged in a circumferential array on the inner circle of the protective cover. The plurality of first elastic protective members and second elastic protective members are arranged in an alternating manner and cover the guide ring groove.

[0021] By adopting the above technical solution, the first elastic protective member and the second elastic protective member are arranged alternately and cover the guide ring groove, and the first elastic protective member, the second elastic protective member and the eccentric shaft cover the guide ring groove, thereby reducing the entry of debris, rainwater, etc. from the guide ring groove into the protective cover and the bottom of the environmental protection. When the eccentric shaft rotates eccentrically, the first elastic protective member and the second elastic protective member are pushed away when passing by, and the first elastic protective member and the second elastic protective member are automatically reset after leaving, so as to avoid affecting the eccentric rotation of the eccentric shaft.

[0022] Furthermore, the internal gear is installed on the eccentric shaft along its axial limiting sliding, and a fixing ring fixed on the eccentric shaft is provided above the internal gear, and an anti-slip ring fixed on the eccentric shaft is provided below the internal gear; an electromagnetic attraction ring is embedded in the lower end face of the fixing ring, and a magnetic ring cooperating with the electromagnetic attraction ring is embedded in the upper end face of the internal gear; the electromagnetic attraction ring is adsorbed by the magnetic ring when energized, and the internal gear is fixed on the lower end face of the fixing ring and meshes with the middle gear; when the electromagnetic attraction ring is powered off, the internal gear slides downward under the action of gravity and rests on the anti-slip ring, and its upper end face is located below the middle gear.

[0023] By adopting the above technical scheme, when the wind energy is normally used to drive the wind energy rotating shaft to rotate, the electromagnetic suction ring is energized and adsorbed with the magnetic ring, and the internal gear is fixed at the lower end of the fixed ring to ensure the internal meshing of the internal gear and the intermediate gear. Under the coordinated transmission action of the wind energy rotating shaft, the first bevel gear, the second bevel gear, the eccentric shaft, the internal gear, the intermediate gear, the external gear, the transmission shaft, the third bevel gear, the fourth bevel gear, and the driving shaft, the auxiliary propeller is driven to rotate and work, and the bulk carrier is driven to sail. When there is no need to drive the auxiliary propeller to work or drive the bracket to rotate and adjust the direction of the wind energy driving shaft, the electromagnetic suction ring is powered off, the internal gear loses the adsorption effect and slides downward along the eccentric shaft under the action of gravity, and is placed on the anti-slip ring to avoid separation from the eccentric shaft, and its upper end face is located below the intermediate gear, the meshing transmission action of the internal gear and the intermediate gear is released, and the transmission drive auxiliary propeller can be stopped, and the eccentric rotation of the internal gear can also be prevented from interfering with the meshing of the internal gear and the intermediate gear.

[0036] like Figure 2 As shown, a drive shaft 7 is provided inside the hull 8 along its length direction and is positioned and rotatably installed. The drive shaft 7 is located below the transmission shaft 6. A third bevel gear 62 coaxial with the transmission shaft 6 is provided at the lower end of the transmission shaft 6.

The main propeller 81 and the power mechanism are the same as those in the prior art, and will not be described in detail. They are only briefly illustrated in the figure.

[0037] like Figure 2 and Figure 3As shown, the deflection motor 15 drives the central shaft 11 to rotate as a whole until the wind energy rotating shaft 2 is perpendicular to the incoming wind direction, and the wind energy is used to blow the blades 31 of the fan blade assembly 3, and the blades 31 drive the wind energy rotating shaft 2 to rotate, and the eccentric shaft 4 is driven to rotate under the meshing action of the first bevel gear 21 and the second bevel gear 41, and the eccentric shaft 4 drives the intermediate gear 5 to rotate under the meshing action of the internal gear 42 and the intermediate gear 5, and the external gear 61 drives the transmission shaft 6 to rotate under the meshing action of the intermediate gear 5 and the external gear 61, and the transmission shaft 6 drives the drive shaft 7 to rotate under the meshing action of the third bevel gear 62 and the fourth bevel gear 71, so that the drive shaft 7 drives the auxiliary propeller 72 to rotate, and assists the main propeller 81 to push the bulk carrier to move, so as to make full use of the wind energy in the navigation process to assist in the propulsion of the bulk carrier, reduce the power consumption of the main propeller 81, save energy and protect the environment, and effectively improve the endurance of the bulk carrier.

[0038] Among them, Figure 2 or Figure 3 As shown, a wind direction sensor 16 connected to the deflection motor 15 for communication control is provided on the bracket 1. The wind direction sensor 16 is used to automatically detect the wind direction, and the deflection motor 15 is automatically controlled according to the wind direction to drive the central axis 11 to rotate, thereby improving the degree of automation.

[0039] like Figure 3 As shown, in order to realize the detachable installation of the blades 31, a plurality of mounting protrusions 22 extending radially outward are arranged in a circumferential array on the outer wall at both ends of the wind energy rotating shaft 2, and the plurality of mounting protrusions 22 correspond to the blades 31 one by one. A U-shaped clip 32 matching the mounting protrusion 22 is arranged at one end of each blade 31 close to the mounting protrusion 22, and the mounting protrusion 22 is clamped in the U-shaped clip 32 and fixedly connected by bolts 23 arranged along the length direction of the wind energy rotating shaft 2.

The eccentric shaft 4 can slide in the guide ring groove 52 as the central shaft 11 rotates, avoiding interference between the eccentric rotation of the protective cover 51, the ring plate 18 and the eccentric shaft 4.

[0044] like Figure 1 and Figure 3As shown, a plurality of first elastic protective members 53 are arranged in a circumferential array on the outer wall of the ring plate 18, and a plurality of second elastic protective members 19 are arranged in a circumferential array on the inner circle of the protective cover 51.
