Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is provided for the rationalization of power consumption in a parking facility, and more particularly to a multilevel parking facility using a solar battery as a power source.

(Prior Art) Three-dimensional parking facilities include vertical circulation type, multi-layer circulation type, and elevator type, which are characterized by having a large parking capacity in spite of a small occupied land. And
Commercial electric power is supplied to all of the electric equipment such as the drive device, lighting equipment, and safety device of the multi-level parking equipment.

(Problems to be solved by the invention) Most of the electric power supplied to the multi-level parking facility is consumed in the daytime when the electricity charge is relatively high. Therefore, as the number of parking lots in the daytime, which is frequently used, increases, the electric power cost increases, so that rationalization by an alternative power source has been desired.

In addition, some of the multi-story parking facilities such as the vertical circulation type are installed in an independent tower. However, this independent tower house was covered with an exterior wall without windows, and this exterior wall was left unutilized.

In view of such conventional circumstances, the present invention provides a multilevel parking facility using a solar battery as a power source, which saves electric power cost by utilizing the exterior wall as a mounting place of the solar battery. It is an object.

(Means for Solving the Problem) A multi-level parking facility using a solar battery of the present invention as a power source is a three-dimensional parking system in which a parking device that circulates and accommodates a car is installed inside a tower house covered by an exterior wall. In a parking facility, a solar cell is attached to the exterior wall, the solar cell and a commercial power source can be used as a power source for the electrical facility in the parking device, and when the power of the solar cell falls below the power of the commercial power source. The electric power of the commercial power source is switched so as to be used for the electric equipment of the parking device.

(Operation) During fine weather in the daytime, the electric power from the solar battery is used as the power source for the parking device. When the vehicle is in the nighttime, cloudy weather, or rainy weather, it is switched to the commercial power source and the parking device continues to operate.

Then, during the daytime or when the weather recovers, the electric power can be switched to the solar cell again.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

The multi-storey parking facility 1 shown in FIG. 1 has a parking facility (not shown) for accommodating a vehicle in a circularly movable manner incorporated inside a tower 3 covered with an exterior wall 2.
For example, a vertical circulation parking device, an elevator parking device, and the like are applied. 4 is a lower entrance.

Outside the upper half of the exterior wall 2, a plurality of solar cells 5 ... Of appropriate size are attached adjacent to each other. The solar cells 5 are for obtaining switchable electric power and commercial power source electric power connected to a parking device (not shown), and are used for electric equipment 17A, 17D of Example 1 or Example 2 described later. AC power AC or DC power DC
In order to supply the electric power, the electric circuit for alternating current 11A or the electric circuit for direct current 11D is provided between the electric equipments 17A and 17D.

(Embodiment 1) An AC electric circuit 11A shown in FIG. 2 has, for example, a solar battery 5, a storage battery 12, a DC-AC converter 13A, and a changeover switch 1.
4A, the power receiving board 15A and the control device 16A are sequentially connected to an AC electrical equipment 17A including an electric motor, a lighting device, a safety device, and the like, and a changeover switch 14A includes a commercial power supply 18 that is AC power AC. Are connected.

In the above configuration, the DC power DC obtained by the solar cell 5 is sent to the storage battery 12. Next, this DC power
DC is converted to AC power AC by the DC-AC converter 13A, and then the changeover switch 14A to the power receiving panel 15A and the control device.
It is supplied to AC electrical equipment 17A via 16A.

Even now, at night or when the weather changes to cloudy or rainy weather and the voltage or current of the AC power AC that enters the changeover switch 14A from the solar cell 5 falls below a certain value.
The alternating-current power AC is switched to the power of the commercial power source 18 by the changeover switch 14A automatically performing the switching operation.

On the other hand, when the voltage or current of the AC power AC entering the changeover switch 14A exceeds a certain value during the daytime or when the weather is recovered, the power source is switched to the solar cell 5 side.

Second Embodiment A DC electric circuit 11D shown in FIG. 3 includes, for example, a solar battery 5, a storage battery 12, a changeover switch 14D, a power receiving board 15D, and a control device 16D including an electric motor, a lighting device, a safety device, and the like. The commercial power supply 18 is connected to the DC electrical equipment 17D sequentially, and the commercial power supply 18 is connected to the changeover switch 14D.
Connected via 3D.

In the above configuration, the DC power DC obtained by the solar cell 5 is used as it is as a driving power source. That is, the DC power DC is transferred from the storage battery 12 to the changeover switch 14D,
Electrical equipment for DC 17D via power receiving board 15D and control device 16D
Sent to.

Then, at night or when the weather continues to deteriorate, the change-over switch 14D is actuated to switch the DC power DC to the commercial power supply 18 converted into DC by the AC-DC converter 13D.

The power supply switching operation to the solar cell 5 side is performed according to the case of the first embodiment.

(Effects of the Invention) In a multi-level parking facility using the solar battery of the present invention as a power source, the solar battery is attached to the exterior wall of a tower building incorporating the parking device, and the solar battery and commercial The power supply is enabled, and when the power of the solar cell is lower than the power of the commercial power supply, the power of the commercial power supply can be switched to be used for the electric equipment of the parking device. Not only is the exterior wall of the vehicle effectively used as a space for securing power, but the power cost required for the parking device can be greatly reduced, which is an excellent advantage.
