Here, some conventional solar panel cleaning devices have a length that covers the panel surface from the top to the bottom edge, and clean by moving approximately horizontally on the panel surface. There are things that exist. With this kind of configuration, compared to a type of cleaning device in which a small cleaning device moves up and down and left and right to clean, the movement of the cleaning device is simple and the distance it moves is short, making it possible to clean in a short time. There is an advantage.

However, this type of cleaning device is large and heavy, so it is difficult to install the device on the solar panel unit or move it from one solar panel unit to the next solar panel unit after cleaning. When transporting and installing large and heavy cleaning equipment, workers have to put in a lot of effort.

Therefore, if you try to clean by moving a conventional small and light cleaning device up, down, left or right, the cleaning device may lack running stability depending on the angle of the panel surface, etc. It takes a long time to finish cleaning, and there is a risk that cleaning will take a long time and be inefficient, especially if the solar panel unit has a large area or if many solar panel units are installed. Ta.

Therefore, the present invention makes it possible to easily move and install the equipment, reduce the labor burden on the worker, reduce the working time, perform the work efficiently, and improve the stability of the work. The objective is to provide solar panel maintenance equipment, such as cleaning equipment, that can be maintained.

In order to achieve such a problem, the present invention provides a solar panel maintenance device that maintains and manages a solar panel unit in which a plurality of solar panels each having a panel surface are installed side by side, and includes an upper end portion of the solar panel unit. A moving mechanism that is hooked onto 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. A solar panel maintenance device is characterized in that the solar panel maintenance device has a device main body equipped with a maintenance mechanism that performs maintenance work on the solar panel unit.

In the present invention, it is preferable that the length of the maintenance mechanism in the apparatus main body in the vertical direction has a length that covers two panel surfaces of the solar panel in the vertical direction.

In the present invention, it is preferable that the maintenance mechanism has a main cleaning device that cleans the panel surface, and a joint cleaning device that cleans the joints provided at the edges of the panel surface.

In the present invention, the joint cleaning means has a rotary brush that performs cleaning by rotating around a rotation axis extending substantially perpendicular to the panel surface, and the rotary brush has bristles in the direction of the panel surface. It is desirable that the direction be approximately perpendicular to the surface.

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

According to the present invention, by making the main body of the device small, the device can be easily moved and installed, reducing the labor burden on the worker, reducing the working time, and working efficiently. be able to. In addition, by having a moving mechanism and mounting the main body of the device there, the solar panel maintenance device can operate stably regardless of the angle of the solar panel unit, etc. Work stability can also be ensured.

In addition, in the present invention, since the vertical length of the maintenance mechanism of the device main body is set to cover two panel surfaces of the solar panel in the vertical direction, sunlight can be Maintenance work for two panels can be performed. Therefore, it is no longer necessary to perform maintenance work on one solar panel unit by moving the device body back and forth many times, and maintenance work on one solar panel unit can be performed with the minimum necessary horizontal movement. In addition, the size and weight of the device itself is smaller than that of a type that covers the entire top and bottom of the solar panel unit, so it can be moved quickly between units, reducing the overall burden on workers. Able to work efficiently.

Moreover, in the present invention, by having a joint cleaning means in addition to the main cleaning means as a maintenance mechanism, the joint cleaning means having a simple structure can remove dirt from the joints that is difficult to remove with the main cleaning means alone. It can be removed reliably using

Further, in the present invention, the joint cleaning means has a rotating brush that rotates around a rotating shaft extending substantially perpendicular to the panel surface, and the rotating brush has bristles in a direction substantially perpendicular to the panel surface. By being oriented in this direction, the cleaning means can be configured to reliably remove dirt from the joint portion, and dirt from the joint portion can be removed more reliably.

Furthermore, in the present invention, the rotating brush is controlled to rotate in the same direction as the moving direction of the device main body by the moving mechanism, making it easier to scrape out dirt from the joints and scrape off floating dirt. This allows you to remove dirt from the joints more reliably.

A pinion gear (not shown) is provided to mesh with the pinion gear (omitted), and these form a rack and pinion structure. Further, the pinion gear is driven by a vertical movement motor 73 disposed in the device main body 30, and by driving the vertical movement motor 73 with the rack and pinion gear meshed, the rack can be driven by a vertical movement motor 73. Along this line, the pinion gear rotates in the vertical direction, and the device main body 30 is configured to move up and down accordingly. Note that here, the rack was configured to have a single edge and mesh with one pinion gear driven by one motor, but it is possible to mesh the rack with two or more pinion gears driven by two or more motors. may be in mesh with each other, and the device body 30 may be moved up and down using two motive powers. By moving the device main body 30 up and down using a plurality of motors, the speed of the vertical movement of the device main body can be maintained at a predetermined speed even when the inclination angle is steep. Further, at this time, if the rack is made double-edged so that the pinion gear meshes with both the left and right sides, holding and driving force can be applied from the left and right sides, so that the rack can be moved in a more stable state.

Further, in this embodiment, a flange-shaped portion (not shown) is provided above the rack (in a direction perpendicular to the panel surface 3) so as to protrude laterally from the teeth of the rack, and this flange-shaped portion is formed into an elongated shape so as to cover the entire inclination direction L in which the rack is formed. This flange-like part holds the pinion gear so that it does not shift upward (in the direction perpendicular to the panel surface 3), and the pinion gear meshed with the rack moves upward (in the direction perpendicular to the panel surface 3). This is designed to prevent the rack from becoming out of alignment due to misalignment.

Further, in this embodiment, a rail member 60 is disposed as a first moving means for mounting the apparatus main body 30 described above and moving it in the lateral direction (horizontal direction) P on the panel surface 3. As shown in FIG. 2, this rail member 60 has two shafts 62 that cover the upper end (rear side) to the lower end (front side) in the inclination direction L, and a plurality of running wheels are attached to this shaft 62. 63 is fixed.

This guide roller 65 is provided to stably move the device main body 30 in the horizontal direction P of the solar panel unit 1, and is hooked onto the upper side surface 1a of the solar panel unit 1. It will be installed. Further, the guide roller 65 is constituted by a wheel that faces the upper side surface 1a, so that the device main body 30 can be moved in the horizontal direction P by the guide roller 65. Note that this guide roller 65 normally faces perpendicularly to the upper side surface 1a, but if it is better to change this angle depending on the angle of the panel surface etc., the angle may be changed. A motor and a control mechanism may be provided so as to be variable.

Further, a control unit 80 is arranged at the lower end (front side) of the rail member 60, and this control unit 80 controls the drive of the cleaning mechanism 40 and the second moving means 70 in the apparatus main body 30, and controls the lateral direction of the rail member 60. It is designed to control movement to P.

The cleaning mechanism 40 may include a shielding brush (not shown) and a water spray pipe (not shown) as a "fluid supply pipe" in addition to the rotating brushes 41 and 42 as part of the cleaning mechanism 40. Further, the frame 61 is mainly made of aluminum from the viewpoint of achieving both weight reduction and strength.

Furthermore, the rail member 60 in this embodiment can be divided into two or more pieces, and can be transported in a divided state during transport, so it can be transported efficiently without taking up space. . In addition, when installing the devices, all they have to do is carry them one by one and connect them, which reduces the burden on the workers.

In this way, cleaning can be performed by mounting the apparatus main body 30 on the rail member 60 and moving the apparatus main body 30 back and forth and left and right using the horizontal moving means and the vertical moving means.

Next, the device main body 30 is placed on the rail member 60 and attached using a predetermined method. At this time, the device main body 30 is stably installed and installed on the rail member 60 because it meshes with the rail member 60 using a rack and pinion, and the left and right wheels (not shown) ride on the shaft 62 of the rail member 60. It can be moved up and down with respect to the rail member 60. In addition, preparations are made by connecting a fluid supply pipe etc. to a water sprinkling pipe etc. (not shown).

Thereby, the device main body 30 and the rail member 60 are combined, and the assembly of the solar panel cleaning device 10 is completed.

Thereafter, while moving the device main body 30 horizontally over the solar panel unit 1 from, for example, the upper left to the upper right, the upper and lower two panels of the panel surface 3 are cleaned. Further, when the device main body 30 reaches the right end, it is moved downward (toward the near 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. When the device main body 30 reaches the left end, cleaning of the solar panel unit 1 is finished, the device main body 30 and the rail member 60 are removed, and the device moves to the next solar panel unit 1.

As described above, the solar panel cleaning device 10 of the embodiment described above has a small device main body, so that the device can be easily moved and installed, reducing the labor burden on the operator. This allows you to reduce work time and work more efficiently. In addition, by having a moving mechanism and mounting the main body of the device there, the solar panel maintenance device can operate stably regardless of the angle of the solar panel unit, etc. Work stability can also be ensured.

Further, according to the solar panel cleaning device 10 of the embodiment described above, the length in the vertical direction of the maintenance mechanism of the main body of the device is set to cover two panel surfaces of the solar panel in the vertical direction, so that the moving mechanism Maintenance work for two solar panels can be performed with one horizontal movement of the device body. Therefore, it is no longer necessary to perform maintenance work on one solar panel unit by moving the device body back and forth many times, and maintenance work on one solar panel unit can be performed with the minimum necessary horizontal movement. In addition, the size and weight of the device itself is smaller than that of a type that covers the entire top and bottom of the solar panel unit, so it can be moved quickly between units, reducing the overall burden on workers. Able to work efficiently.
[Embodiment 2 of the invention]
Next, a second embodiment of the present invention will be described using FIGS. 2 and 3. In addition, here, things that are different from the first embodiment of the invention described above will be explained, and the same components will be given the same reference numerals and the explanation will be omitted.

As shown in FIGS. 2 and 3, the solar panel cleaning device 10 of this embodiment has a cleaning mechanism 40 as a "maintenance mechanism" including rotating brushes 41, 42 and rotating brush motors 43, 44. In addition to the main cleaning means for cleaning the panel surface 3 by cleaning the panel surface 3, there is also a joint cleaning means 50 for cleaning the joints at the edge 5 of the panel surface 3.

The joint cleaning means 50 of this embodiment is provided on both left and right sides of the lower part of the device main body 30, and has a rotating shaft 51 extending substantially perpendicularly to the panel surface 3. It has a rotating brush 52 that rotates around the center to perform cleaning, and a rotating brush motor 53 that serves as a power for rotating the rotating brush 52.

Further, the rotating brush 52 has bristles in a direction substantially perpendicular to the panel surface 3, and is configured to easily scrape out dirt from the joints with its bristles.

Furthermore, the rotating brush 52 of this embodiment is controlled to rotate in the same direction as the left-right moving direction of the device main body 30 with respect to the left-right moving direction by the first moving means 60. That is, when cleaning is performed so that the main body 30 of the apparatus moves to the right, the rotating brush 52 rotates to the right, and conversely, when cleaning is performed so that the main body 30 of the apparatus moves to the left. During this process, the rotating brush 52 rotates to the left.

As a result, when moving to the right, for example, the front (right side) rotary brush 52 is rotated clockwise to scrape out dirt from the joint and float it, and then when the main cleaning means 41 and 42 spray water, The water and the floating dirt are mixed, and finally the rear (left side) rotating brush 52 is rotated clockwise to scrape off the floating dirt along with the water, thereby making it possible to reliably clean the dirt in the joint area. .

As described above, the solar panel cleaning device 10 of the second embodiment described above has, in addition to the first embodiment described above, a joint cleaning means 50 in addition to the main cleaning means 41 to 44 as a maintenance mechanism. By doing so, it is possible to reliably remove dirt from the joints that is difficult to remove using the main cleaning means 41 to 44 alone using the joint cleaning means 50 having a simple configuration.

Further, according to the solar panel cleaning device 10 of the second embodiment described above, the joint cleaning means 50 includes the rotating brush 52 that rotates about the rotating shaft 51 extending substantially perpendicularly to the panel surface 3. However, since the rotating brush 52 has its bristles in a direction substantially perpendicular to the panel surface 3, it can be used as a cleaning means that is configured to reliably remove dirt from the joint area, which is more reliable. You can remove dirt from the joints.

Further, according to the solar panel cleaning device 10 of the second embodiment described above, the rotating brush 52 is controlled to rotate in the same direction as the moving direction of the device main body 30 by the moving mechanism 60, thereby cleaning the joints. This makes it easier to scrape out dirt from the joints, makes it easier to scrape off loose dirt, and more reliably removes dirt from the joints.

Furthermore, in the above-described embodiment, as the solar panel unit 1, there is a gap S between the solar panels 2 adjacent to each other along the horizontal direction P, but between the solar panels 2 adjacent to each other along the inclination direction L. Although the one without the gap S was used, it is not limited to this. For example, the solar panel unit 1 is a solar panel unit 1 in which there is no gap between adjacent solar panels along the horizontal direction P and there is a gap between adjacent solar panels along the inclination direction L. May be used. Furthermore, you may use the solar panel unit 1 in which there is no gap both between the solar panels adjacent to each other along the horizontal direction P and between the solar panels adjacent to each other along the inclination direction L.

In addition, the present invention may be applied to a solar panel cleaning device that simultaneously performs cleaning using a brush or blade and cleaning using a blow device in parallel.

Furthermore, in the embodiments described above, the movement mechanism is operated by the operator using a remote control, but this is not limited to this, and sensors may be attached to the device body (or the operation body and the rail member). The vehicle may also be equipped with automatic operation. For example, in the case of a solar panel unit with four panels in the vertical direction as described above, when you press the cleaning start button, the sensor checks the current location, cleans from left to right, and the sensor confirms that it has reached the right end. Once completed, the device moves downward, then cleans from right to left, and when the sensor confirms that it has reached the left end, it stops, and so on. You can leave it there.
