Description

The present invention relates to a small mobile solar power generation system that is supposed to be used as a power supply during disasters or as a power source for outdoor activities.

Solar power generation devices premised on use in the event of a power failure or outdoors without a power source have become widespread. By combining solar panels with batteries and control devices, it has become possible to use the power supply during power outages.

The existing photovoltaic power generation device is a movable but relatively large device mainly for supplying commercial power of 100V to 220V such as Patent Literature 1, Patent Literature 2, and Patent Literature 3. Or, there are many ultra-small ones that are intended to be used for charging mobile phones, etc., via USB output terminals, and are likely to be able to be brought into a railcar on a daily basis for movement. There are few outputs suitable for use with personal computers and loudspeakers.

In the case of the idea of Patent Document 1, it is necessary to fold the panel at the start of movement, and it is necessary to unfold the panel at the time of installation. Will occur. Moreover, since the panel is removed and folded, power generation during movement is impossible.

In the case of the devices of Patent Document 1 and Patent Document 2, since the switch and outlet-shaped terminal are exposed on the side surface, there is a risk of breakage or fouling during movement, or touching the switch or terminal accidentally during movement. Doing so may cause an accident such as an electric shock or malfunction.

Neither Patent Document 1, Patent Document 2, or Patent Document 3 is a cause of catching at the time of movement, and it is not assumed that the electric cables are required to be stored inside when moved. In addition, the wheel moving type requires operations such as braking the wheel and lifting the wheel, and if the wheel supports part or all of its weight even during installation, even if all wheels are braked However, there is a risk of unexpected movement due to wind or earthquake.
