Description

This invention relates to a natural energy power generation device that can be easily installed in a disaster prevention warehouse.

The following natural energy power generation devices have been proposed:
1. Technology for installing a solar power generation system on the roof of an existing carport (Patent Document 1).
2. A carport equipped with a solar power generation system and a disaster prevention storehouse (Patent Document 2).

JP 2014-120538 A JP 2016-44515 A

Since the system disclosed in Patent Document 1 does not include a wind power generation device, it is not possible to generate power at night, in rainy weather, or when snow accumulates on the solar power generation device.
In Patent Document 2, the solar power generation device and the disaster prevention warehouse share the same support pillars, making it difficult to apply this to existing warehouses.

Disaster prevention warehouses are often prefabricated buildings or converted storerooms, but for durability and crime prevention reasons, they generally have no windows or other light sources. As their main purpose is to store food, drinking water, and household goods, many of them do not have lighting inside. However, when inspecting the warehouse or replacing equipment, the lack of lighting inside the warehouse reduces workability.

If a power grid is to be connected from outdoors to a disaster prevention warehouse, extensive construction work will be required and electricity bills will have to be paid.
When installing a wind turbine or solar power generation system mounting bracket on the roof of a disaster prevention warehouse, holes must be drilled into the roof, which, in the worst case scenario, could allow water to seep into the warehouse through the holes.
When installing a power generation system and mounting frame on the roof of a disaster prevention warehouse, the load-bearing capacity of the roof must be verified, and if the load-bearing capacity is insufficient, reinforcement work on the roof and the building itself will be required.
In order to avoid construction work on disaster prevention warehouses, if wind or solar power generation equipment is to be installed around the warehouse, it will be necessary to secure installation space around the warehouse.

The purpose of this invention is to provide a natural energy power generation device that does not require securing a new installation location and can be easily installed in a disaster prevention warehouse without major construction work.

The natural energy power generation device of this invention comprises a stand having a stand upper part located in the space above the disaster prevention storehouse and legs not connected to the disaster prevention storehouse, a solar power generation panel installed on the stand upper part of the stand, and a wind turbine for wind power generation installed on the stand.

According to this configuration, a solar power generation panel and a windmill for wind power generation are installed on a stand having an upper part of the stand located in the space above the disaster prevention warehouse and legs that are not connected to the disaster prevention warehouse. By using the space above the disaster prevention warehouse in this way, there is no need to secure a new installation location for the solar power generation panel, windmill, etc. The legs of the stand are not connected to the disaster prevention warehouse, that is, they are separate structures from the disaster prevention warehouse, so the solar power generation panel and the windmill can be easily installed without carrying out major construction work in the disaster prevention warehouse, and can be applied to existing disaster prevention warehouses. The electricity generated by the rotation of the solar power generation panel or the windmill can be used as a power source for, for example, lighting in the disaster prevention warehouse. Since both the solar power generation panel and the windmill are installed, electricity can be generated by the rotation of the windmill even when electricity cannot be generated by the solar power generation device at night or in rainy weather. Even when electricity cannot be generated by the windmill when there is no wind during good weather during the day, electricity can be generated by the solar power generation panel. In this way, the solar power generation panel and the windmill can be easily installed without carrying out major construction work, which reduces costs and increases the versatility of this natural energy power generation device.

The system may include a power storage device that stores the electricity generated by the solar power generation panel and the generator connected to the wind turbine, and a control device that controls the storage of the generated electricity in the power storage device. In this case, the control device controls the storage of the electricity generated by the solar power generation panel and the generator in the power storage device. Under normal circumstances, the generated electricity can be used, for example, for lighting inside and outside the disaster prevention warehouse, or as a power source for operating security cameras, etc. The electricity stored in the power storage device can be used, for example, as an emergency power source in the event of a power outage or disaster in the area where the disaster prevention warehouse is installed.

The control device and the power storage device may be installed on the stand or inside the disaster prevention warehouse. If the control device and the power storage device are installed on a stand that is a separate structure from the disaster prevention warehouse, additional construction work on the disaster prevention warehouse can be reduced. If the control device and the power storage device are installed inside the disaster prevention warehouse, the natural energy power generation device can be installed by performing additional construction work such as running wiring through the disaster prevention warehouse.

The generator that generates electricity by rotating the windmill may be mounted on the frame. In this way, if the generator is mounted on a frame that is a separate structure from the disaster prevention warehouse, additional construction work on the disaster prevention warehouse can be reduced.

The natural energy power generation device of this invention comprises a stand with a stand upper part located in the space above the disaster prevention storehouse and legs that are not connected to the disaster prevention storehouse, a solar power generation panel installed on the stand upper part of the stand, and a wind turbine for wind power generation installed on the stand, so there is no need to secure a new installation site and it can be easily installed in the disaster prevention storehouse without major construction work.

<About stand 1>
As shown in Figures 1 to 3, the platform 1 has a platform upper part 8 located in the space above the disaster prevention storehouse 6, and legs 9 that are separate structures and not connected to the disaster prevention storehouse 6, i.e., separated from the disaster prevention storehouse 6. A plurality of legs 9 (four in this example) are erected around the disaster prevention storehouse 6, and the platform upper part 8 is connected to the upper ends of these legs 9. As shown in Figure 3, the platform upper part 8 has an outer peripheral frame member 8a that is rectangular in plan view as shown in Figure 3, and a plurality of inner frame members 8b. In this example, the platform 1 is installed so that the disaster prevention storehouse 6 fits within the rectangular frame of the outer peripheral frame member 8a in plan view of the platform 1.

The outer peripheral frame material 8a has first and second outer peripheral frame parts 8a1 and 8a2 and third and fourth outer peripheral frame parts 8a3 and 8a4. The first and second outer peripheral frame parts 8a1 and 8a2 each extend parallel to the longitudinal direction of the disaster prevention storehouse 6 and are formed to be longer than the width of the disaster prevention storehouse 6. The third and fourth outer peripheral frame parts 8a3 and 8a4 each extend parallel to the depth direction of the disaster prevention storehouse 6 and are formed to be longer than the depth of the disaster prevention storehouse 6.

One longitudinal end of the first and second outer periphery frame portions 8a1, 8a2 is joined to one longitudinal end of the third and fourth outer periphery frame portions 8a3, 8a4, and the other longitudinal end of the first and second outer periphery frame portions 8a1, 8a2 is joined to the other longitudinal end of the third and fourth outer periphery frame portions 8a3, 8a4. The first to fourth outer periphery frame portions 8a1, 8a2, 8a3, 8a4 form an outer periphery frame member 8a having a rectangular frame shape in plan view.
Each of the internal frame members 8b extends, for example, parallel to the depth direction of the disaster prevention storehouse 6 and is installed from the first outer peripheral frame portion 8a1 to the second outer peripheral frame portion 8a2. The multiple internal frame members 8b are provided, for example, at regular intervals.

<Solar power generation device 2>
As shown in Figs. 1 and 2, the solar power generation device 2 has a solar power generation panel 2a installed on an upper part 8 of a frame, and a control device 4A. The solar power generation panel 2a is a panel-shaped panel formed by arranging a plurality of solar battery cells. In this example, the control device 4A is installed on a leg 9 of the frame 1. The control device 4A is composed of a charge controller that stores the power generated by each solar power generation panel 2a in a power storage device 5. As this charge controller, a maximum power point tracking control method (abbreviated as MPPT) or a pulse control method (PWM control method) is applied. As the power storage device 5, for example, a lead battery, a lithium ion battery, a nickel metal hydride battery, or the like is applied.

<Wind power generation device 3>
2 and 4, the wind power generation device 3 includes a wind turbine 7, a generator 10 that generates power by the rotation of the wind turbine 7, a power storage device 5, and a control device 4B. The control device 4B is provided separately from the control device 4A of the solar power generation device 2, and is housed in the same housing as the control device 4A. This housing is fixed to the legs 9. However, the housing may include parts common to the control devices 4A and 4B.

The windmill 7 is a vertical-axis windmill in which a plurality of blades 13 (two in this example) are connected via arms 12 to a main shaft (not shown) that is rotatable on the top of a support 11 and is supported coaxially with the support 11. In this example, a support member 14 is connected to the top of one leg 9, and the support 11 is installed so that it extends upward from the upper end of the support member 14. The support 11 is made of a round steel pipe or the like. The main shaft is rotatably supported at its lower end on the support 11 by a double-row rolling bearing (not shown) provided in the upper end of the support 11. The plurality of blades 13 are connected to the arms 12 so as to extend vertically around the main shaft 11. The plurality of blades 13 and the arms 12 form a rotor.

The generator 10 is provided inside the upper end of the support 11, and its input shaft is connected to the main shaft. A power storage device 5 is provided below the housing of the control devices 4A and 4B in the leg 9. The control device 4B includes an AC/DC converter that converts the AC power generated by the generator 10 into a voltage that can be stored in the power storage device 5, a power generation controller that controls the power generation by the rotation of the windmill 7, and an inverter that converts the power stored in the power storage device 5 into a sine wave AC similar to commercial AC power, or into a square wave AC. The generated power is sent to an outlet or terminal provided in the disaster prevention storehouse 6 and can be consumed inside or outside the disaster prevention storehouse 6.

<Action and effect>
According to the natural energy power generation device described above, the solar power generation panel 2a and the windmill 7 are installed on a stand having a stand upper part 8 located in the space above the disaster prevention warehouse 6 and a leg part 9 not connected to the disaster prevention warehouse 6. By using the space above the disaster prevention warehouse 6 in this way, it is not necessary to secure a new installation location for the solar power generation panel 2a, the windmill 7, etc. The leg part 9 of the stand 1 is not connected to the disaster prevention warehouse 6, that is, it is a separate structure separated from the disaster prevention warehouse 6, so that the solar power generation panel 2a and the windmill 7 can be easily installed without performing large-scale construction work on the disaster prevention warehouse 6. The windmill 7, the control devices 4A, 4B, and the storage device 5 are installed on the leg part 9 of the stand 1, so that the windmill 7, the control devices 4A, 4B, and the storage device 5 can be installed firmly and stably.

The electricity generated by the rotation of the solar power generation panel 2a or the windmill 7 can be used as a power source for lighting, etc. in the disaster prevention storehouse 6. Since both the solar power generation panel 2a and the windmill 7 are installed, electricity can be generated by the rotation of the windmill 7 even when electricity cannot be generated by the solar power generation device 2 at night, during rainy weather, etc. Even when electricity cannot be generated by the windmill 7 when there is no wind during good weather during the day, electricity can be generated by the solar power generation panel 2a. The solar power generation panel 2a and the windmill 7 can be easily installed in the existing disaster prevention storehouse 6 without large-scale construction work, which reduces costs and increases the versatility of this natural energy power generation device.

The control device 4A stores the electricity generated by the solar power generation panel 2a in the power storage device 5, and the control device 4B stores the electricity generated by the generator 10 in the power storage device 5. The electricity stored in the power storage device 5 can be used as an emergency power source in the event of a power outage or disaster in the installation area of the disaster prevention warehouse 6, for example. The control devices 4A, 4B and the power storage device 5 are installed on the frame 1, which is a separate structure from the disaster prevention warehouse 6, so additional construction work on the disaster prevention warehouse 6 can be reduced.

<Other embodiments>
In the following description, parts corresponding to matters previously described in each embodiment are given the same reference symbols, and duplicated description is omitted. When only a part of the configuration is described, the other parts of the configuration are the same as the previously described embodiment unless otherwise specified. The same action and effect are achieved from the same configuration. It is possible to combine not only the parts specifically described in each embodiment, but also partially combine the embodiments, provided that there is no particular problem with the combination.

As shown in FIG. 5, the control devices 4A and 4B and the power storage device 5 may be installed inside the disaster prevention warehouse 6. In this case, a natural energy power generation device can be installed by performing additional work such as running wiring through the disaster prevention warehouse 6.

As shown in FIG. 6, wind turbines 7 may be installed on each of multiple legs 9. In this example, control devices 4A, 4B and a power storage device 5 electrically connected to these wind turbines 7 are installed on the legs 9, but they may also be installed in the disaster prevention storehouse 6 as in FIG. 5. Although not shown below, either the control device or the power storage device may be installed on the stand and the other installed in the disaster prevention storehouse. Solar power generation panels may be installed not only on the top of the stand but also on the legs.

In each of the above-described embodiments, the solar power generation panel 2a is installed flat along the upper part of the frame 8, but as shown in FIG. 7, the solar power generation panel 2a may be installed at an angle to the horizontal plane of the upper part of the frame 8 so that it can easily receive sunlight.

In a plan view of the stand 1, the stand 1 may be installed so that a portion of the disaster prevention storehouse 6 extends beyond the rectangular frame of the outer peripheral frame material 8a of the upper part 8 of the stand.
For example, as shown in Figure 8 (a), when viewed in a plane, the stand 1 may be installed so that both front and rear end portions of the disaster prevention warehouse 6 extend beyond the rectangular frame of the peripheral frame material 8a of the upper part 8 of the stand.
As shown in Figure 8 (b), the stand 1 may be installed so that, in a plan view of the stand 1, both left and right ends of the disaster prevention storehouse 6 extend beyond the rectangular frame of the outer peripheral frame material 8a of the upper part 8 of the stand.

The wind turbine can also be installed on the top of the frame. The wind turbine is not limited to the vertical axis type, but may be a propeller type.
The shape of the upper part of the stand in a plan view is not limited to a rectangle, but can also be formed into a polygonal, circular, elliptical, or other shape depending on the shape of the disaster prevention warehouse, for example.
As a reference proposal example, instead of the disaster prevention warehouse 6, it is also possible to use a warehouse such as a container or a prefabricated hut.

The above describes the mode for carrying out the present invention based on the embodiment, but the embodiment disclosed herein is illustrative in all respects and is not restrictive. The scope of the present invention is indicated by the claims, not the above description, and is intended to include all modifications within the meaning and scope of the claims.
