It is about a farming type solar power generation panel inspection device.

In addition to the need for various environmental regulations for environmental preservation, new and renewable energy is in the spotlight as the dangers of existing energy power generation facilities such as thermal power generation or nuclear power generation and problems caused by emission of various pollutants have emerged.

Among these new and renewable energies, power generation using solar light, which is cheap in new construction cost and highly convenient to install, has attracted the most attention, and solar panels are generally used for power generation facilities using such solar light.

In addition, Korean Patent Registration No. 10-2091493 discloses a remote management system for a solar power plant that can check and manage the temperature of the solar panel and the climate condition of the area where the solar panel is installed using an unmanned flying observer. .

However, the photovoltaic panel inspection device using a drone as described above determines whether the photovoltaic panel is out of order when the temperature of the photovoltaic panel is higher than normal. There is a problem with falling.

In addition, since the solar power generation panel inspection device using such a drone needs to fly the drone, it is difficult to operate because it requires the user to have flying skills to operate the drone, and the user's inexperience in operation causes the drone to fall toward the solar power generation panel. If it does, there is a problem that not only the drone but also the solar power generation panel is damaged.

In addition, recently, as the number of farming-type solar power generation panels installed on farmland for growing crops has increased in order to maximize the use efficiency of the site, inspection of the solar power generation panels as well as the growth status of crops or irrigation Demand for inspection devices capable of managing crops by checking their conditions together or supplying pesticides or nutrients to crops is increasing.

And, in the agricultural solar power generation panel inspection device according to an embodiment of the present invention, the user rotates the spacing adjusting member 67 in the forward and reverse direction to move it along the longitudinal direction of the forward and backward arm 65, thereby moving the spacing adjusting member 67 ) And the restoring force of the spring 69 can be adjusted by adjusting the spacing between the support portion 64, so that even if the drive wheel 100 is worn out due to long-term use, it is possible to maintain the gripping force between the drive wheel 100 and the rail 30 have possible advantages.

In addition, in the agricultural solar power generation panel inspection device according to an embodiment of the present invention, the user remotely monitors the irrigation status and growth information of crops through a thermal imaging camera 72 and a spectrum sensor 73, or sprays chemicals. Through the unit 80, the drug can be remotely sprayed on the crops, so it has the advantage of saving manpower for managing the crops.

In addition, the agricultural solar power generation panel inspection device according to an embodiment of the present invention can adjust the angle of the spectrum sensor 73 through the rotation support 90, so that the spectrum sensor 73 collects the spectrum image. By expanding, it has the advantage of being able to manage a wide area of crops with a small number of devices.
