Here, some conventional solar panel cleaning devices have a length that covers from the upper end to the lower end of the panel surface, and cleaning is performed by moving on the panel surface in a substantially horizontal direction. There is something that is. With such a configuration, the movement of the cleaning device is simple and the moving distance is shorter than that of the type of cleaning device in which a small cleaning device moves up, down, left and right to perform cleaning, and cleaning can be performed in a short time. There is a merit.

However, in such a type of cleaning device, the device itself becomes large and heavy, so that the device is installed in the solar panel unit, and the solar panel unit that has been cleaned is replaced with the next solar panel unit. It took a lot of labor for the worker to carry and install a large and heavy cleaning device when moving to.

Therefore, if the conventional small and light cleaning device is moved up, down, left and right to clean it, the running stability of the cleaning device may be lacking depending on the angle of the panel surface, etc., and because of its small size, cleaning is performed. It takes time to finish, especially when it is for a large area solar panel unit or when many solar panel units are installed, there is a possibility that cleaning will take a long time and there will be a problem of inefficiency. It was.

Therefore, according to the present invention, the device can be easily moved and installed, the labor burden on the operator can be reduced, the work time can be reduced, the work can be performed efficiently, and the work stability is also improved. An object of the present invention is to provide a solar panel maintenance device such as a cleaning device that can be secured.

In order to achieve such a problem, the present invention is a solar panel maintenance device for maintaining and managing a solar panel unit in which a plurality of solar panels having panel surfaces are arranged side by side, and the upper end portion of the solar panel unit. A moving mechanism that is hooked on and held by the solar panel unit, has a length that covers the vertical direction of the solar panel unit, and moves laterally along the panel surface, and is mounted so as to be movable in the vertical direction with respect to the moving mechanism. The solar panel maintenance device is characterized by having a main body of the device provided with a maintenance mechanism for performing maintenance work on the solar panel unit.

In the present invention, it is desirable that the vertical length of the maintenance mechanism in the device main body has a length that covers two vertical lengths of the panel surface of the solar panel.

In the present invention, it is desirable that the maintenance mechanism has a main cleaning means for cleaning the panel surface and a joint cleaning means for cleaning the joint portion at the edge of the panel surface.

In the present invention, the joint cleaning means has a rotary brush that rotates around a rotation axis extending in a direction substantially perpendicular to the panel surface to perform cleaning, and the rotary brush has a flocking direction of the panel. It is desirable that the direction is substantially perpendicular to the surface.

In the present invention, it is desirable that the rotating brush is controlled so as to rotate in the same direction as the moving direction of the apparatus main body by the moving mechanism.

According to the present invention, by reducing the size of the apparatus main body, the apparatus can be easily moved and installed, the labor burden on the operator can be reduced, the working time can be reduced, and the work can be performed efficiently. be able to. In addition, since it has a moving mechanism and the device body is mounted here, the solar panel maintenance device can be operated stably regardless of the angle of the solar panel unit. Work stability can also be ensured.

Further, in the present invention, since the vertical length of the maintenance mechanism of the apparatus main body is set to cover two vertical lengths of the panel surface of the solar panel, sunlight can be obtained by one lateral movement of the moving mechanism and the apparatus main body. Maintenance work for two panels can be performed. Therefore, it is not necessary to reciprocate the device main body many times for one solar panel unit to perform maintenance work, and it is possible to perform maintenance work for one solar panel unit with the minimum necessary lateral movement. In addition, since the size and weight of the main body of the device are smaller than the type that covers the entire vertical direction of the solar panel unit, it is possible to quickly move between units, reducing the burden on workers as a whole. You can work efficiently.

Further, in the present invention, since the maintenance mechanism includes the joint cleaning means in addition to the main cleaning means, the joint cleaning means having a simple structure can remove dirt on the joints that cannot be easily removed by the main cleaning means alone. Can be reliably dropped using.

Further, in the present invention, the joint cleaning means has a rotary brush that rotates about a rotation axis extending in a direction substantially perpendicular to the panel surface, and the rotary brush has a flocking direction substantially perpendicular to the panel surface. By the direction, the cleaning means can be used as a cleaning means having a structure for surely removing the dirt on the joint portion, and the dirt on the joint portion can be removed more reliably.

Further, in the present invention, since the rotating brush is controlled to rotate in the same direction as the moving direction of the device main body by the moving mechanism, it is easy to scrape off the dirt on the joint portion and it is easy to scrape off the floating dirt. It is possible to remove dirt from the joints more reliably.

Further, when the device main body 30 reaches the right end, the device main body 30 is moved downward (front side) by about the length of the device main body 30 in the vertical direction, and is moved horizontally from right to left. As a result, cleaning is performed in a zigzag manner up to the lower end of the panel surface 3. Then, when the device main body 30 reaches the left end, cleaning of the solar panel unit 1 is completed, the device main body 30 and the rail member 60 are removed, and the solar panel unit 1 is moved to the next one.

As described above, in the solar panel cleaning device 10 of the above-described embodiment, the device can be easily moved and installed by reducing the size of the device body, and the labor burden on the operator can be reduced. It is possible to reduce the work time and work efficiently. In addition, since it has a moving mechanism and the device body is mounted here, the solar panel maintenance device can be operated stably regardless of the angle of the solar panel unit. Work stability can also be ensured.

Further, according to the solar panel cleaning device 10 of the above-described embodiment, the vertical length of the maintenance mechanism of the device main body is set to be the length covering two vertical panels of the panel surface of the solar panel, so that the moving mechanism And the maintenance work for two solar panels can be performed by one lateral movement of the main body of the device. Therefore, it is not necessary to reciprocate the device main body many times for one solar panel unit to perform maintenance work, and it is possible to perform maintenance work for one solar panel unit with the minimum necessary lateral movement. In addition, since the size and weight of the main body of the device are smaller than the type that covers the entire vertical direction of the solar panel unit, it is possible to quickly move between units, reducing the burden on workers as a whole. You can work efficiently.
