[0024] Example, see Figure 1 、 Figure 2 A bidirectional output planetary gear reduction device, mounted on a generator for power generation, includes a fixed rod 1, a first power assembly, and a second power assembly. Fixed rod 1 is mounted on the ground and supports the first and second power assemblies in mid-air. The first power assembly is connected to the other end of fixed rod 1, and the second power assembly is connected to the first power assembly. The power output directions of the first and second power assemblies are opposite. Through the connection between the first and second power assemblies, both can meet the requirements of bidirectional power output under the support of fixed rod 1, providing a more flexible power transmission method for the generator.

[0025] In the embodiment of the present disclosure, the first power assembly includes a first power rod 2, one end of which is sleeved on a fixed rod 1 and rotatably connected to the fixed rod 1. A sun gear 3 is fixedly mounted on the first power rod 2, and planetary gears 4 are connected to the outer side of the sun gear 3. A first inner ring gear 5 is connected to the planetary gears 4. A first drive assembly is mounted on the first power rod 2. The first drive assembly drives the first power rod 2 to rotate (for example, the first power rod 2 rotates clockwise in this case), the first power rod 2 drives the sun gear 3 to rotate clockwise, the sun gear 3 drives the planetary gears 4 to rotate counterclockwise, and the planetary gears 4 rotate counterclockwise while simultaneously revolving clockwise around the sun gear 3, thereby realizing power transmission.

[0026] In the embodiment of the present disclosure, the sun gear 3 is meshed with the planetary gears 4, and the planetary gears 4 are meshed with the first inner ring gear 5. The meshing connection ensures the efficiency and stability of the power transmission.

[0027] Specifically, three planetary gears 4 are provided, and are arranged in a circular array on the periphery of the sun gear 3 with the axis of the sun gear 3 as a base point.

[0028] In the embodiment of the present disclosure, a connecting assembly is mounted on the planetary gears 4. Specifically, the connecting assembly includes a connecting post 6 mounted on each planetary gear 4. A second inner gear ring 7 is mounted on the connecting post 6. The second inner gear ring 7 has a through hole through which the connecting post 6 is rotatably connected to the second inner gear ring 7. The connecting assembly connects the first power assembly to the second power assembly.

[0029] In the embodiment of the present disclosure, a support ring 8 is fixedly mounted on one side of the second inner gear ring 7. The support ring 8 is located between the first inner gear ring 5 and the second inner gear ring 7. The first power rod 2 passes through the inner cavity of the support ring 8 and is rotatably connected to the support ring 8. The support ring 8 is used to limit the second power assembly.

[0030] In the embodiment of the present disclosure, the second power assembly includes a second power rod 9, which is sleeved on the first power rod 2 and is rotatably connected to the first power rod 2. A power gear 10 is fixedly installed at one end of the second power rod 9, which is rotatably connected to the support ring 8. The power gear 10 is meshed with a driven gear 11, which is rotatably connected to the support ring 8. The driven gear 11 is meshed with the second inner ring gear 7, and a second drive assembly is installed on the second power rod 9. The first power rod 2 passes through the drive gear, the support ring 8 and the sun gear 3 in sequence and is rotatably connected to the fixed rod 1. Assume that at this time, the planetary gear 4 revolves clockwise while driving the second inner ring gear to rotate clockwise, the second inner gear 7 drives the driven gear 11 to rotate clockwise, and the driven gear 11 drives the power gear 10 and the second power rod 9 to rotate counterclockwise, thereby causing the second drive assembly to rotate counterclockwise. This achieves the goal of the first power rod 2 and the second power rod 9 having opposite rotation directions.

[0031] In the embodiments of the present disclosure, referring to Figure 3 The first driving assembly includes a plurality of first blade brackets 12 mounted on the first power rod 2, and first fan blades 13 are mounted on the first blade brackets 12.
