Therefore, there is a problem that a facility for installing the cleaning device on the photovoltaic power generation panel is required separately, and the configuration for controlling the moving cleaning of the cleaning body is complicated.

In the case where the outer frame body must be installed, it is necessary to prepare an outer frame body that matches the size of the solar power generation panel to be installed, which increases the cost. In addition, since the size of the outer frame is usually considered to be large, there is a problem that labor is required for installation. Accordingly, there has been a demand for the development of a cleaning device for a photovoltaic power generation panel that can be stably operated while solving the above problems.

The photovoltaic power generation panel 1 is usually installed on a roof, a rooftop, the ground, or the like so as to be mainly facing south with an inclination angle, but may be installed horizontally. In this case, since the cleaning device 10 is not suspended from the photovoltaic power generation panel 1 and the cleaning device 10 is put on the photovoltaic power generation panel 1, the suspension portion 110 is not necessary, and the suspension portion 110 is installed. If so, the weight balance becomes worse, and the straightness of the cleaning device 10 becomes worse.

  For this reason, it became possible to install the cleaning apparatus 10 in the photovoltaic power generation panel 1 of all aspects, ensuring the straightness of the cleaning apparatus 10 by making the suspension part 110 detachable.

The air blow-off mechanism 260 is a member for removing dust scattered on the panel surface and cleaning it by blowing strong wind on the surface (light-receiving surface) of the photovoltaic power generation panel 1 and applying wind pressure. Then, it is the structure installed in a pair at the right and left both ends of the cleaning body 200. In this embodiment, the compressed air for applying power to the wind of the air blow-off mechanism 260 is supplied from a compressed air generating mechanism (not shown) installed inside or outside the cleaning body 200. .

  In addition, when the cleaning body 200 reaches the left and right ends of the photovoltaic power generation panel 1, the air blow-off mechanism 260 installed on the end of the photovoltaic power generation panel 1 is activated to remove the separated dust from the panel. It is configured to blow away. Thereby, even if it is the edge part of the photovoltaic power generation panel 1 which the cleaning means 210 does not reach, it becomes possible to remove dust, and it becomes possible to clean the photovoltaic power generation panel 1 over the entire surface.

  As shown in FIG. 10, the suction collecting mechanism 250 is configured by a pair of suction nozzles 252 and a pair of squeegees 254 a and 254 b. The suction nozzle 252 is a nozzle for sucking dust that has been peeled off by the cleaning unit 210, and is provided near the cleaning unit 210 at a symmetrical position. Further, the squeegees 254a and 254b are a pair of left and right members that are in contact with the photovoltaic power generation panel 1 and move by pressing dust such as dust adhering to the surface (light receiving surface) of the panel, as shown in FIG. The solar power generation panel 1 is disposed so as to be freely contacted and separated at a position between the pair of suction nozzles 252.

  In this embodiment, when the cleaning body 200 moves, the squeegees 254a and 254b descend toward the light receiving surface of the photovoltaic power generation panel 1 when the squeegee 254a (or 254b) on the opposite side of the traveling direction moves down. The dust is pressed and moved in contact with. At this time, the other squeegee 254b (or 254a) remains elevated. As a result, the squeegee 254a (or 254b) wipes and collects dust, such as dust, left by the suction nozzle 252, and the suction nozzle 252 can suck and collect the dust again, which is likely to accumulate dust, such as dust. Even so, it is possible to efficiently clean the photovoltaic power generation panel 1.

  Since the cleaning device 10 according to the present invention is configured to detachably install the cleaning body 200, the cleaning device 200 can be an inspection device 20 in which an inspection body 300 for inspecting a photovoltaic power generation panel is installed instead of the cleaning body 200.

  The inspection camera 310 can be used by appropriately selecting one or more of the thermography camera 311 and the night vision camera 312. The thermography camera 311 is a camera that shoots by converting the surface temperature of the photovoltaic power generation panel 1 into color information. When the solar cell is damaged, the damaged solar cell generates heat, so that a defective portion can be detected by a temperature change. Further, the night vision camera 312 can inspect a defective portion of the photovoltaic power generation panel 1 in a situation where no light is irradiated such as at night.

  The transmission unit 320 is a unit for transmitting the image captured by the inspection camera 310 and / or failure / damage information detected by the EL inspection apparatus 313 to an external device. In this embodiment, the transmission unit 320 is based on a wireless communication standard. Communication device.
