More specifically, the artificial tunnel structure 110 is constructed on the railway. That is, the artificial tunnel structure 110 is formed as a tunnel structure in which the railway extends inside.
In addition, the solar power generation module 120 is mounted on the artificial tunnel structure 110, and the wind power generation modules 130A and 130B may be installed inside the artificial tunnel structure 110 or outside the artificial tunnel structure 110. The above-described automatic solar cell panel cleaning apparatus is mounted on the solar power generation module of the solar cell panel.
Further, the wind power generation modules 130B installed inside the artificial tunnel structure 110 may be installed on both sides of the railway, and the wind power generation modules 130A installed outside the artificial tunnel structure 110 may be installed on both sides of the artificial tunnel structure 110.
In general, since the railway is installed on flat ground without obstacles, as much sunlight as possible may be introduced into the artificial tunnel structure 110.
As described above, the wind power generation module may include a first wind power generation module 130A installed outside the artificial tunnel structure and a second wind power generation module 130B installed inside the artificial tunnel structure and located on both sides of the railway.
The first wind power generation module 130A is configured to generate electricity using natural wind flowing near the artificial tunnel structure 110.
The second wind power generation module 130B is configured to generate electricity using the wind flowing by the train traveling inside the artificial tunnel structure 110.
In addition, the first and second wind power generation modules 130A and 130B include a rotation detection sensor (not shown) and a rotating device (not shown) for detecting the rotation of the blade, respectively.
The controller is connected to the solar power generation module 120, the wind power generation modules 130A and 130B, and the railway artificial tunnel electric device 140, and controls them so that the electricity generated by the solar power generation module 120 and the wind power generation modules 130A and 130B is transmitted to the power storage unit or the railway artificial tunnel electric device (not shown).
The artificial tunnel electrical device (not shown) includes a display device, an air purifier, a detection sensor, a fluid supply device and the like.
The air purifier may be formed in a square or cylindrical shape.
In addition, the air purifier is formed to extend in a traveling direction of the train in the artificial tunnel structure, thereby improving air purification efficiency.
The fluid supply device is configured to supply fluid into the artificial tunnel structure, and may provide fluid for fire and quarantine. The detailed technical configuration for this will be described below.
In addition, the controller includes a wind speed sensor and a wired or wireless communication module to operate the rotating device of the wind power generation modules 130A and 130B, and receives information on the rotation status of the blade in real time through the rotation detection sensor of the blade to rotate the blade selectively based on the received information.

More specifically, the solar power generation unit includes a plurality of solar cell panels 11.
In addition, the plurality of solar cell panels are coupled so that the plurality of solar cell panels slide and move to fold and unfold. The above-described automatic solar cell panel cleaning apparatus is mounted on the solar power generation unit.
The support unit 12 includes panel supports 12a and central supports 12b.
The panel supports 12a are configured to support the plurality of solar cell panels 11 folded on one side, and the central supports 12b are configured to support the solar cell panels at a central portion of the river when the plurality of solar cell panels are unfolded.
In addition, a cylindrical or square air purifier may be installed on the central support 12b in an extension direction of the river. Therefore, the support unit may be implemented as one large air purifier.
To this end, the panel supports 12a are installed at the riverside of the river, thus a plurality of panel supports may be included.
In addition, the plurality of solar cell panels 11 are supported by the panel supports 12a located on the riverside, such that shade is generated by the plurality of solar cell panels 11 on the riverside.
Guide supports 12c are placed between the panel support 12a and the central support 12b to connect them, and the guide supports 12c may support the sides of the solar cell panels while guiding them to smoothly move.
To this end, the guide support 12c has a groove portion formed therein, by which the solar cell panel is supported.
In addition, the support unit may further include a central connection rod 12d for connecting the central supports 12b in the longitudinal direction. That is, the central connection rod 12d extends in the longitudinal direction of the river.
The plurality of solar cell panels 11 are unfolded by a solar cell panel driving device in a folded state on the panel supports 12a, and are unfolded to the central supports 12b while being supported by the guide supports 12c.
That is, the panel supports 12a are located on both sides of the riverside, and the central supports 12b are located in the central portion of the river. In this case, the plurality of solar cell panels are moved to selectively unfold from the riverside toward the central portion of the river.
Accordingly, the plurality of solar cell panels may be spread out to cover the river, thus to maximize solar power generation. When natural disasters such as strong winds or typhoons are expected, the panels may be safely kept in the folded state, and by arranging the panels along the river, there are no obstacles preventing sunlight from entering, and thereby maximizing solar power generation.
The central support 12b may be equipped with a river purifier and a water sprayer.
In addition, the present invention may be implemented by installing a plurality of solar cell panels so that they are spread out from the central support 12b to the panel support 12a.
In addition, the automatic solar cell panel cleaning apparatus according to the present invention and the solar cell panel cleaning system using the same may be implemented by being mounted on a bus platform, a barn, a greenhouse structure, a river structure and the like.
As such, embodiments of the present invention have been described with reference to the accompanying drawings, but it should be understood by those skilled in the art that the present invention may be implemented in other specific embodiments without changing the technical idea and essential characteristics of the invention. Accordingly, it should be understood that the above-described embodiments are only intended to illustrate the present invention and are not intended to limit the scope thereof in all aspects.
