A Ferris wheel type wind power generation system according to Embodiment 1 of the present disclosure will be described with reference to FIGS. 1A to 1C. FIG. 1A is a front view showing a schematic configuration of a Ferris wheel type wind power generation system according to Embodiment 1, and FIG. 1B is a side view thereof. The Ferris wheel type wind power generation system includes a unit holding ring 10 and a plurality of wind power generation units 20 installed around the outer periphery of the unit holding ring 10. The unit retaining ring 10 is supported by a support structure 30.

The unit holding ring 10 is rotatable around a horizontally held shaft portion 11. In this embodiment, a plurality of spokes 12 connect the shaft portion 11 and the outer periphery of the unit holding ring 10, and a so-called tension type structure is adopted. A plurality of spokes 12 pull the outer periphery of the ring toward the center to maintain the shape of the unit retaining ring 10. In this disclosure, the unit holding ring 10 will be described as a tension type ring, but the unit holding ring 10 may have a strong (so-called compression type) structure that stands on its own through a frame such as a truss. The unit retaining ring 10 can be manufactured using the structure of a rotating ring of a Ferris wheel.

In this embodiment, the shaft portion 11 is provided with an inspection rotation mechanism 13, and the unit holding ring 10 is rotated around the shaft portion 11 by a gear mechanism or the like disposed inside the inspection rotation mechanism 13. can be done. The rotation mechanism 13 for inspection may have a drive mechanism such as a motor therein, or may receive a drive force for moving the gear mechanism from the support structure 30. In this embodiment, the unit holding ring 10 does not need to constantly rotate, and is used for inspection in order to move the wind power generation unit 20 to be inspected to a predetermined position (lowermost position) when inspecting the wind power generation unit 20, which will be described later. The unit holding ring 10 is rotated by the rotation mechanism 13.

The wind power generation unit 20 is a unit that generates power using wind power. In this embodiment, 24 wind power generation units 20 having the same structure are installed at equal intervals outside the outer periphery of the unit holding ring 10. Note that the number of wind power generation units 20 is not limited to 24, and any number may be arranged depending on the sizes of the wind power generation units 20 and the unit holding ring 10.

An example of the configuration of the wind power generation unit 20 will be described with reference to FIGS. 2A and 2B. FIG. 2A is a front view showing a schematic configuration of the wind power generation unit 20, and FIG. 2B is a side view thereof. Each of the wind power generation units 20 is a small wind power generation device, and includes a blade 21 that rotates due to wind flow, a nacelle 22 that converts the rotation of the blade 21 into electrical energy, and a nacelle 22 that is connected to the unit retaining ring 10.

The wind power generation unit 20 may include a wind body (diffuser) 24 around the blades (windmill) 21 . As shown in FIG. 2B, the wind body 24 has a cylindrical structure that expands from the wind inlet to the wind outlet, and increases the wind speed flowing into the rotating surface of the blade 21, that is, the inflow energy. can be done.

Although the size of the wind power generation unit 20 can be arbitrarily set, since a plurality of wind power generation units 20 are installed around the unit holding ring 10, a relatively small structure is adopted. For example, the diameter of the windmill can be approximately 1 m to 10 m. In FIG. 2A, a windmill with six blades 21 is illustrated, but the number of blades of the windmill can be designed arbitrarily. Although the wind body 24 is not an essential configuration, the wind body 24 makes it possible to dramatically improve the power generation capacity of the small wind power generation unit 20.

Returning to FIG. 1A, the electric power generated by each wind power generation unit 20 can be extracted to the outside through, for example, the shaft portion 11 of the unit retaining ring 10, and further through the inside of the support structure portion 30.

The support structure section 30 includes a rotation mechanism, rotates around the axis of the columnar structure (vertical axis), and can change the direction of the shaft section 11 of the unit holding ring 10 within a horizontal plane. Thereby, the wind turbine of the wind power generation unit 20 installed on the unit holding ring 10 can be oriented in an optimal direction according to the wind direction. An inspection work structure 31 may be provided at the bottom of the support structure 30, and a drive mechanism 32 for rotating the support structure 30 may be provided at the lowest power generation system installation structure. can. Inside the inspection work structure 31, a measuring device for checking the state of each wind power generation unit 20 and a management device for controlling the entire wind power generation system may be installed. Note that the rotation operation of the unit holding ring 10 and the operation of directing it in the optimum direction depending on the wind direction can utilize electricity generated by this Ferris wheel type wind power generation system.

When installing the Ferris wheel-type wind power generation system of this embodiment on the ground, a lower stabilizing pillar (not shown) is further installed underground under the power generation system installation structure, so that the entire system is attached to the ground. It may be stabilized by Moreover, when installing the Ferris wheel type wind power generation system of this embodiment on the ocean, the power generation system installation structure part may be installed on a floating body floating on the ocean. In the following embodiments, the Ferris wheel type wind power generation system will be described as being installed on the ground, but an offshore wind power generation system can also be realized with a similar structure.

FIG. 1C is a partially enlarged view of the Ferris wheel type wind power generation system of this embodiment, and shows a side view when a wind power generation unit 20 is lowered to the lowest position. The upper surface (rooftop) of the inspection structure 31 is close to the wind power generation unit 20. The inspection work structure 31 is provided with, for example, an elevator for an inspector, stairs, a ladder, etc. inside, so that the inspector can go up to the roof of the inspection work structure 31.

The roof of the inspection work structure 31 can be a flat and wide space, and the position can be such that the worker can directly touch the wind power generation unit 20 and work by simply standing there. It is.

During inspection or repair work, for example, if a wind power generation unit 20 is found to have an abnormality in power generation by a measuring device, the unit holding ring 10 is rotated and the wind power generation unit 20 in which the abnormality is found is moved to the bottom. After lowering it, the operator can perform maintenance work on the roof of the inspection work structure 31. Even if it is difficult to repair and the equipment needs to be replaced, it is only necessary to replace the defective wind power generation unit 20, and there is no need to replace or repair the entire large-scale power generation system. can reduce costs. Furthermore, even when performing maintenance on a plurality of wind power generation units 20, the wind power generation units 20 to be maintained can be lowered to the bottom one after another, and the worker does not have to move to perform inspection work. There is no need for special work at heights, as is required for large wind power generation systems.

A supplementary explanation of the structure of the support structure 30 based on FIG. 1C is that the columnar structure of the support structure 30 has a drive shaft 33 at its center, and the shaft cover or shaft holding pipe 34 covers the periphery of the drive shaft 33. It may also be a structure. At this time, a structure may be adopted in which the shaft holding pipe 34 does not rotate, but the drive shaft inside thereof rotates to change the direction of the shaft portion 11 of the unit holding ring 10. Further, a driving force transmission mechanism (such as a belt) may be arranged inside the shaft holding pipe 34 in order to apply a driving force to the inspection rotation mechanism 13 that rotates the unit holding ring 10.
