The data collection unit 200 collects basic data for predicting the possibility of lightning. The data collection unit 200 first collects weather data by accessing the Korea Meteorological Administration's weather data open API. In addition, extended weather data is also collected through weather sensors such as thermometers and hygrometers installed on or near the solar structure 10.

The data collected in the data collection unit 200 is transmitted to the lightning probability prediction unit 210.

The lightning strike possibility prediction unit 210 predicts the possibility of lightning strike through big data-based machine learning on lightning occurrence conditions, based on meteorological data collected from the Korea Meteorological Administration's Open API, especially lightning forecast data and field weather data. This calculates the possibility of lightning striking near solar power facilities.

The lightning probability prediction unit 210 displays the probability of a lightning strike as a percentage, and when the probability increases above a set standard, it transmits this to the manager and transmits a drive command to the drive control unit 380 of the lightning rod unit 300, which will be described later. .

A detection unit 333 is provided on the ground corresponding to the formation position of the sensing unit 331 to periodically detect the magnetic field signal to determine the location of the sensing unit 331.

Through the sensing unit 331, the earth pressure and the end position of the grounding line 330 are periodically checked to predict the possibility of disasters such as landslides or ground collapse. In other words, if the earth pressure measured by the sensing unit 331 is higher than the reference value, it can be determined that soil is flowing toward the solar power generation facility (1). Conversely, if the earth pressure is lowered, there is a risk of ground collapse due to soil loss. You can judge.

By confirming the location of the sensing unit 331, judgment data for predicting the possibility of ground collapse or landslide can be obtained, thereby further increasing the accuracy of predicting the possibility of disaster.

The main body 320 includes a first spray nozzle 340 that sprays water toward the solar power generation facility 1, and a second spray nozzle 350 that sprays water toward the outside of the solar power generation facility 1. It is provided.

Lightning occurs when negative charges are discharged from clouds toward the ground, and these discharges are directed to places where charges tend to flow. One of the conditions in which discharge is likely to occur is a sharp object made of metal, and therefore the lightning rod 310 is provided. Another condition in which discharge is easy to occur is related to humidity; the drier it is, the easier discharge is.

In other words, the possibility of discharge occurring in places with high humidity is relatively low. Therefore, when the possibility of a lightning strike increases, the first spray nozzle 340 sprays water toward the solar power generation facility (1) to increase the surrounding humidity of the solar power generation facility (1), thereby causing lightning to strike the solar power generation facility (1). ) to avoid falling.

The second spray nozzle 350 is installed on the main body 320 to spray water toward the outside of the solar power generation facility 1. The second injection nozzle 350 is used to prevent the flame from moving toward the solar power generation facility (1) when a fire occurs outside the solar power generation facility (1).

If a fire occurs near the solar power generation facility (1) due to a lightning strike or other reasons, water is sprayed through the second spray nozzle (350) when the fire spreads toward the solar power generation facility (1). Prevent the fire from spreading until it is extinguished or the fire department arrives.

A thermal imaging camera 370 is provided to determine whether to spray water from the second spray nozzle 350, and the thermal imaging camera 370 detects a surrounding fire situation through thermal image images. Sensing information is transmitted to the drive control unit 380 so that water is sprayed through the second spray nozzle 350.

And it includes a hail determination unit 510 that determines whether it is hail through the vibration or impact frequency applied to the hail detection sensor 500.

The module protection unit 600 includes a first rotation rod 610, a second rotation rod 620, and a first rotation rod 610 installed adjacent to the bottom and top of the solar power module 420, respectively. A first rod sprocket 611, a second rod sprocket 621, and a first rod sprocket ( It includes a chain 630 that is hung on 611 and the second load sprocket 621 to transmit rotational force, and a cover plate 650 that is fixed to the chain 630 and rotates together with the chain 630.

The first rotation rod 610 and the second rotation rod 620 extend in parallel along the width direction of the solar power module 420 and are supported on the module frame 410 so as to be rotatable. The first rotation rod 610 and the second rotation rod 620 support the chain 630 and cover plate 650, which will be described later, to rotate in a direction surrounding the sun and the power generation module 420, so that solar power generation can be achieved. It is preferable that they are installed at a predetermined distance apart from the end of the module 420.

First rod sprockets 611 are installed at both ends of the first rotation rod 610, and second rod sprockets 621 are installed at both ends of the second rotation rod 620. Two chains 630 are installed to connect the sprocket 611 and the second load sprocket 621. Therefore, rotational force is transmitted to the first rotation rod 610 and the second rotation rod 620 through the chain 630, and rotation of one side causes the other rotation rod to rotate together.

In this case, since the cover plate 650 covers the upper part of the solar power generation module 420, the solar power generation module 420 can be protected by the cover plate 650 even if hail falls.

A scraper 651 protruding toward the solar power generation module 420 is formed on the cover plate 650 on the inner side facing the upper surface of the solar power generation module 420.
