Japanese Unexamined Patent Publication No. 2014-12038 Japanese Unexamined Patent Publication No. 2016-44515

Since Patent Document 1 does not include a wind power generation device, it cannot generate power at night, in the rain, or when snow accumulates on the solar power generation device.
In Patent Document 2, since the solar power generation device and the support of the disaster prevention warehouse are shared, it is difficult to apply to the existing warehouse.

Many disaster prevention warehouses are prefabricated or remodeled storage, but from the viewpoint of durability and crime prevention, a structure without light such as windows is common. Since the main purpose of disaster prevention warehouses is to store food, drinking water, household goods, etc., many warehouses are not equipped with lighting equipment. However, when inspecting the disaster prevention warehouse or replacing equipment, workability deteriorates if there is no lighting equipment in the warehouse.

When drawing grid power from the outdoors into a disaster prevention warehouse, large-scale construction work is required and electricity costs must be paid.
When installing a windmill or a stand for a solar power generation device on the roof of a disaster prevention warehouse, it involves drilling holes in the roof, so in the worst case, the warehouse will be flooded from the hole processing part.
When installing a power generation device and a gantry on the roof of a disaster prevention warehouse, it is necessary to verify the load-bearing performance of the roof, and if the load-bearing performance is insufficient, reinforcement work of the roof and the building itself is required.
When installing wind power and solar power generation equipment around the disaster prevention warehouse in order to avoid construction work on the disaster prevention warehouse, it is necessary to secure an installation location around the warehouse.

An object of the present invention is to provide a renewable energy power generation device that does not need to secure a new installation place and can be easily installed in a disaster prevention warehouse without major construction work.

The renewable energy power generation device of the present invention includes a pedestal having an upper part of a gantry located in the space above the disaster prevention warehouse, a pedestal having legs not joined to the disaster prevention warehouse, and a photovoltaic power generation panel installed on the pedestal upper part of the pedestal. It is provided with a wind turbine for wind power generation installed on the gantry.

According to this configuration, a solar power generation panel and a wind turbine for wind power generation are installed on a pedestal having an upper part of the gantry located in the space above the disaster prevention warehouse and a leg portion not joined to the disaster prevention warehouse. By using the space above the disaster prevention warehouse in this way, it is not necessary to secure a new installation location for solar panels, wind turbines, etc. Since the legs of the gantry are not joined to the disaster prevention warehouse, that is, they have a separate structure separated from the disaster prevention warehouse, solar power generation panels and wind turbines can be easily installed without major construction work in the disaster prevention warehouse. It can also be applied to existing disaster prevention warehouses. The electric power generated by the rotation of the photovoltaic power generation panel or the wind turbine can be used as a power source for, for example, lighting in a disaster prevention warehouse. Since both the photovoltaic power generation panel and the wind turbine are installed, power can be generated by the rotation of the wind turbine even when the photovoltaic power generation device cannot generate electricity at night or in rainy weather. Even if the wind turbine cannot generate electricity when there is no wind, such as when the weather is fine in the daytime, the photovoltaic power generation panel can generate electricity. As described above, since the photovoltaic power generation panel and the wind turbine can be easily installed without performing a large-scale construction, the cost can be reduced and the versatility of the renewable energy power generation device can be enhanced.

A storage device for storing electric power generated by the photovoltaic power generation panel and a generator connected to the wind turbine, and a control device for controlling the storage of the generated electric power in the power storage device may be provided. .. In this case, the control device controls to store the electric power generated by the photovoltaic power generation panel and the generator in the power storage device. In normal times, the generated power can be used, for example, as lighting inside and outside the disaster prevention warehouse, or as a power source for operating a security camera or the like. The electric power stored in the power storage device can be used as an emergency power source in the event of a power failure or disaster in the installation area of the disaster prevention warehouse, for example.

The control device and the power storage device may be installed in the gantry or the disaster prevention warehouse. If the control device and the power storage device are installed on a stand that has a separate structure from the disaster prevention warehouse, the additional work for the disaster prevention warehouse can be reduced. When the control device and the power storage device are installed in the disaster prevention warehouse, the renewable energy power generation device can be installed by performing additional work such as passing wiring through the disaster prevention warehouse.

The generator that generates electricity by the rotation of the wind turbine may be installed on the gantry. In this way, when the generator is installed on a stand that has a separate structure from the disaster prevention warehouse, additional work on the disaster prevention warehouse can be reduced.

The renewable energy power generation device of the present invention includes a pedestal having an upper part of a gantry located in the space above the disaster prevention warehouse, a pedestal having legs not joined to the disaster prevention warehouse, and a photovoltaic power generation panel installed on the pedestal upper part of the pedestal. Since it is equipped with a wind turbine for wind power generation installed on the gantry, it is not necessary to secure a new installation place, and it can be easily installed in a disaster prevention warehouse without major construction work.
