Problems to be solved by the invention

Here, in the conventional cleaning device for a photovoltaic panel, the cleaning device has a length extending from an upper end to a lower end of the panel surface, and is configured to move in a substantially horizontal direction on the panel surface to perform cleaning. With such a configuration, compared to a cleaning device of a type in which a small-sized cleaning device performs cleaning by moving up and down and left and right, the cleaning device has advantages in that the operation is simple, the operation distance is short, and the cleaning can be completed in a short time.

However, since the cleaning device of this type is large in size and heavy in weight, it requires a great deal of labor for an operator to carry and install the large and heavy cleaning device when the device is installed on a solar panel unit or when the device is moved from a solar panel unit that has been cleaned to the next solar panel unit.

Therefore, if a small and light cleaning device is used to clean the solar panel unit in the vertical and horizontal directions, it takes time to complete the cleaning, and particularly, in the case of cleaning a large-area solar panel unit, or in the case of installing a large number of solar panel units, there is a possibility that the cleaning takes a long time and the efficiency is low.

Therefore, an object of the present invention is to provide a maintenance device for a photovoltaic panel such as a cleaning device, which can easily move and install the device, reduce the labor load of an operator, reduce the work time, and perform efficient work.

Means for solving the problems

In order to achieve the above object, the present invention provides 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, the solar panel maintenance device including: a device main body having a maintenance mechanism for performing maintenance work on the solar panel unit; and a moving mechanism for moving the device main body along the plate surface, wherein the solar panel maintenance device is configured to be capable of switching between a 1 st maintenance state and a 2 nd maintenance state, in the 1 st maintenance state, a connecting body formed by connecting and integrating a plurality of split bodies provided with the maintenance mechanism along the plate surface in a substantially one direction is used as the device main body, the maintenance operation is performed by using a 1 st moving member for moving the connecting body along a substantially orthogonal direction which is substantially orthogonal to the substantially one direction in which the connecting body is connected, and in the 2 nd maintenance state, a small body formed by connecting and integrating 1 of the split bodies or a number of split bodies smaller than the number of split bodies forming the connecting body along the plate surface in the substantially one direction is used as the device main body without using other split bodies The maintenance work is performed by using, as the moving mechanism, the 1 st moving member for moving the small body in the orthogonal direction or the 2 nd moving member different from the 1 st moving member and the 3 rd moving member for moving the small body in the substantially one direction.

In the present invention, it is preferable that the maintenance work is performed by reciprocating the connecting member on the plate surface in the substantially orthogonal direction by the 1 st moving member in the 1 st maintenance state, and the maintenance work is performed by reciprocating the small member on the plate surface in the substantially orthogonal direction by the 1 st moving member or the 2 nd moving member and moving the small member on the plate surface in the substantially one direction by the 3 rd moving member in the 2 nd maintenance state.

In the present invention, it is preferable that the photovoltaic panel maintenance apparatus is configured such that the 1 st moving member is formed in a state of being divided into pieces corresponding to the respective divided bodies, and the 1 st moving member is also connected to function by connecting and integrating the divided bodies.

In the present invention, it is preferable that, in the 2 nd maintenance state, a rail member is disposed so as to be engaged with an upper end position of the solar light panel unit and to extend to a lower end of the solar light panel unit, the small body is provided on the rail member, the small body is configured to be movable in a rail direction of the rail member, and the small body is configured to be movable in the orthogonal direction by the rail member.

In the present invention, it is preferable that, in the 2 nd maintenance state, a pinion gear provided on the small body meshes with a rack gear disposed on the guide rail member, and the small body is configured to move in the guide rail direction of the guide rail member.

In the present invention, it is preferable that a ledge portion protruding from the teeth of the rack is formed above the rack of the rail member, and the ledge portion prevents the pinion gear engaged with the rack from being displaced upward, so that the engaged state of the rack and the pinion gear is maintained.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present invention, maintenance work can be performed by setting the apparatus main body to the following two states: a connected body formed by connecting and integrating a plurality of divided bodies, and a small body formed by the divided bodies less than the connected body. Therefore, the state of the apparatus main body can be selected according to the work environment, and the operator can select the most appropriate state to perform the maintenance work.

In the present invention, by specifying the operation of the apparatus main body in each of the 1 st maintenance state and the 2 nd maintenance state more specifically, the state of the apparatus main body can be selected more appropriately according to the work environment, and the operator can further select the most appropriate state to perform the maintenance work.

In the present invention, the 1 st moving member, which is a relatively large-sized device structure used in the 1 st maintenance state, is formed in a state of being divided into the respective divided bodies, so that it is possible to adopt a structure that can be used by an operator by simply connecting the divided bodies, and it is possible to reduce the burden on the operator to perform work.

In the present invention, the installation of the solar panel maintenance device can be relatively easily performed by providing the small-sized body to the rail member in the 2 nd maintenance state.

In the present invention, by using the rack and pinion to move the small profile in the direction of the rail member in the 2 nd maintenance state, even when the inclination of the plate surface is gentle or substantially horizontal, the movement in the direction of the rail member can be reliably performed.

In the present invention, since the brim-shaped portion protruding from the teeth of the rack is provided above the rack, when the small body is likely to float from the plate surface in a case where the inclination is steep, the float of the pinion gear meshing with the rack can be pressed, and the pinion gear can be prevented from coming off from the state of meshing with the rack. As a result, the small profile can be prevented from coming off the guide rail member, and maintenance work can be performed reliably.

The solar panel cleaning device 10 of the present embodiment cleans the surface of the solar panel unit 1 as shown in fig. 1 and 2. The solar panel cleaning device 10 includes: a device main body provided with a cleaning mechanism as a "maintenance mechanism" that performs a cleaning operation as a maintenance operation on the solar panel unit 1; and a moving mechanism for moving the device body on the solar panel unit 1.

As shown in fig. 3, the solar panel cleaning device 10 of the present embodiment is configured to use, as a device main body, a configuration in which: the plurality of divided bodies 30A to 30D are connected to each other and configured as the connected body 20 as shown in fig. 1, or the divided bodies 30A to 30D are partially configured as the small-sized body 30 as shown in fig. 2, and the divided bodies 30A to 30D can be used as the connected body 20 or as the divided bodies 30A to 30D can be used as the small-sized body 30.

The apparatus main body is configured to be capable of performing cleaning work by appropriately changing the state to a 1 st maintenance state as shown in fig. 1 or a 2 nd maintenance state as shown in fig. 2, the 1 st maintenance state being a state in which a coupling body 20 is used, the coupling body 20 having a size that covers the entire longitudinal direction L of the solar panel unit 1, and the coupling body 20 performs cleaning work while moving in the lateral direction P, and the 2 nd maintenance state being a state in which a small-sized body 30 is used, the small-sized body 30 having a size that does not cover the entire longitudinal direction L of the solar panel unit 1, and the small-sized body 30 performs cleaning work while moving in the longitudinal direction L and the lateral direction P.

The 1 st maintenance state is selected when there are many solar panel units 1 for cleaning work (maintenance work), and it is desired to shorten the work time for performing work on one solar panel unit 1. The 2 nd maintenance state is selected from a case where the number of the solar panel units 1 to be cleaned (maintenance work) is small, and even if the work time for performing work on one solar panel unit 1 becomes slightly long, it is desired to reduce the weight of the apparatus to be carried or installed, thereby reducing the burden on the operator.

First, the solar panel unit 1 of this embodiment will be described.

In general, the solar panel unit 1 is installed in a state where the panel 3 is inclined or a state where the panel 3 is horizontal. That is, when the solar panel unit 1 is viewed from the side (south side) on which sunlight is irradiated, the back side surface 1a of the panel 3 is positioned above the front side surface 1b or is positioned horizontally to the front side surface 1 b. In fig. 1, the lateral direction P is a substantially horizontal direction ("orthogonal direction" in the present invention), and the longitudinal direction L is a direction (one direction "in the present invention) substantially parallel to the inclined plate surface 3 and substantially perpendicular to the horizontal direction (lateral direction P). In the following description, a direction indicated as a longitudinal direction L in fig. 1 is referred to as an oblique direction L.

When the connecting pin 39A is inserted into the insertion hole 39B, the connectors 56A and 56B of the divided shower pipes 59A and 59B are also coupled. Thus, in this embodiment, the coupling of the divided bodies 30A, 30B and the coupling of the divided watering pipes 59A, 59B can be performed simultaneously. In this embodiment, a fixing member K is provided for reliably fixing the coupling portions 36A and 36B after the coupling portions are coupled. The 3 rd coupling part 36C and the 4 th coupling part 36D and the 5 th coupling part 36E and the 6 th coupling part 36F are also coupled and fixed in the same manner as the 1 st coupling part 36A and the 2 nd coupling part 36B.

The solar panel cleaning device 10 of the present embodiment can change the types and the number of the segments 30A to 30D when used in the 1 st maintenance state according to the length of the solar panel unit 1 to be cleaned in the inclined direction L. For example, when the length of the solar panel unit in the inclined direction L is short, the 1 st segment 30A and the 4 th segment 30D can be connected to each other to form a shorter connecting member than the connecting member shown in fig. 1.

When the length of the solar panel unit in the inclined direction L is long, a total of 6 divided bodies, that is, the 1 st divided body 30A, a plurality of (for example, two) 2 nd divided bodies 30B, a plurality of (for example, two) 3 rd divided bodies 30C, and the 4 th divided body 30D, can be connected to form a connected body longer than the connected body in fig. 1.

Here, instead of at least one of the 1 st segment 30A to the 4 th segment 30D, a plurality of types of segments having different lengths from each other are prepared in advance, so that the size of the connected body can be easily changed in accordance with the solar panel units of a plurality of sizes.

As described above, the control unit 55 is provided for the operator to control the operation of the photovoltaic panel cleaning apparatus 10 using a remote controller or the like. Specifically, the control unit 55 executes control for driving the movement motor 54 to horizontally move the coupling body 20, control for driving the brush motors 43A to 43D and 44A to 44D to clean the plate surface 3, control for spraying water from the water spray pipe 59, and the like. The control unit 55 of this embodiment starts driving the movement motor 54 and the brush motors 43A to 43D and 44A to 44D after a predetermined standby time (for example, 3 to 5 seconds) has elapsed after the start of spraying water by the spray pipe 59. Accordingly, the rotation of the rotating brushes 41A to 41D and 42A to 42D is started in a state where the surface of the plate surface 3 is sufficiently wetted, and therefore, the cleaning effect at the work start position of the photovoltaic panel cleaning apparatus 10 can be sufficiently achieved. The length of the standby time can be adjusted substantially steplessly in accordance with a program change or the like.

The control unit 55 also has a function of digitally displaying the remaining battery level and the battery voltage. Further, the operator can accurately monitor the battery state by blinking the power supply lamp when the battery remaining amount and the battery voltage are lower than normal values.

The control unit 55 has a function of blinking a warning lamp when the operation is abnormally stopped due to an abnormal load on each driving part of the solar panel cleaning device 10. The warning lamp blinks in different colors (e.g., blue and red) according to the place of occurrence of the load, and the like. Thus, when the solar panel cleaning device 10 is abnormally stopped, the abnormality occurrence portion can be easily identified.

Next, the operation of the 1 st maintenance state of this embodiment will be described.

When the sunlight panel cleaning apparatus 10 of this embodiment is installed in the sunlight panel unit 1, first, the guide roller 21 provided in the 1 st segment 30A is engaged with the upper side surface 1a of the sunlight panel unit 1, and the guide roller 21 instructs the 1 st segment 30A.

Next, the 2 nd segment 30B is disposed below the 1 st segment 30A, and the 1 st protruding portion 37A and the 1 st retracting portion 38A provided in the 1 st coupling part 36A of the 1 st segment 30A are engaged with the 2 nd retracting portion 38B and the 2 nd protruding portion 37B provided in the 2 nd coupling part 36B of the 2 nd segment 30B, respectively, to couple the 1 st segment 30A and the 2 nd segment 30B.

At this time, as shown in fig. 4 and 5, the coupling pin 39A provided in the 1 st protruding portion 37A is engaged with the insertion hole 39B provided in the 2 nd retracting portion 38B, and the coupling pin 39A provided in the 2 nd protruding portion 37B is engaged with the insertion hole 39B provided in the 1 st retracting portion 38A. At this time, the two pairs of connectors 56A and 56B provided in the 1 st divided sprinkler tube 59A and the 2 nd divided sprinkler tube 59B are also coupled by one contact while the coupling pin 39A is inserted into the insertion hole 39B. Then, the 1 st projecting portion 37A and the 2 nd retracting portion 38B are fixed by the fixing member K, and the 2 nd projecting portion 37B and the 1 st retracting portion 38A are fixed by the fixing member K, and a connector of an unillustrated control electric wiring is connected.

Next, similarly to the coupling of the 1 st segment 30A and the 2 nd segment 30B, the 3 rd segment 30C is disposed below the 2 nd segment 30B, and the 2 nd segment 30B and the 3 rd segment 30C are coupled by engaging the 3 rd protruding portion 37C and the 3 rd retracted portion 38C provided in the 3 rd coupling portion 36C of the 2 nd segment 30B with the 4 th retracted portion 38D and the 4 th protruding portion 37D provided in the 4 th coupling portion 36D of the 3 rd segment 30C.

Similarly to the connection of the 1 st segment 30A and the 2 nd segment 30B, the 4 th segment 30D is disposed below the 3 rd segment 30C, and the 3 rd segment 30C and the 4 th segment 30D are connected by engaging the 5 th protruding portion 37E and the 5 th retracting portion 38E provided in the 5 th connecting portion 36E of the 3 rd segment 30C with the 6 th retracting portion 38F and the 6 th protruding portion 37F provided in the 6 th connecting portion 36F of the 4 th segment 30D.

Thereby, all the divided bodies 30A to 30D are connected, and the assembly of the cleaning device main body 30 is completed. In this embodiment, when the connecting portions 36A to 36D are connected, the rotating brushes 41A to 41D and the rotating brushes 42A to 42D of the connecting body 20 are arranged so as to partially overlap when viewed from the horizontal direction P, and are short → long and long → short → long → short. As a result, in the cleaning mechanism 40 of the present embodiment, as shown in fig. 1, the rotary brushes 41A to 41D and 42A to 42D are arranged in a staggered manner.

Then, the plate surface 3 is cleaned while moving the connecting member 20 on the solar panel unit 1, for example, from left to right. Then, if necessary, the plate surface 3 may be cleaned again while moving the coupling member 20 from right to left on the solar panel unit 1.

In the solar panel cleaning device 10 of the present embodiment, a frame is mainly made of aluminum, for example, to reduce the weight. Further, since the structures of engaging the protruding portions 37A to 37D and the retracting portions 38A to 38D, inserting the coupling pin 39A into the insertion hole 39B, fixing by the fixing member K, and the like are provided, the coupling portions 36A to 36D are firmly coupled. Therefore, when the solar panel cleaning device 10 is moved for cleaning the next solar panel unit 1 after cleaning of 1 solar panel unit 1 is completed, the solar panel cleaning device can be moved in an assembled state without being disassembled into the divided bodies 30A to 30D and moved.

As described above, the photovoltaic panel cleaning apparatus 10 according to the present embodiment can change the types and the number of the segments 30A to 30D in the 1 st maintenance state according to the length of the photovoltaic panel unit 1 to be cleaned in the inclined direction L. For example, when the length of the solar panel unit in the inclination direction L is short, the 1 st segment 30A and the 4 th segment 30D are connected to each other, and a solar panel cleaning device having a shorter connection member than that in fig. 1 can be obtained. When the length of the solar panel unit in the inclined direction L is long, a solar panel cleaning device having a longer connected body than the case of fig. 1 can be obtained by connecting a total of 6 divided bodies such as the 1 st divided body 30A, the two 2 nd divided bodies 30B, the two 3 rd divided bodies 30C, and the 4 th divided body 30D.

Next, a configuration in a case where the photovoltaic panel cleaning apparatus 10 is used in the 2 nd maintenance state will be described. As shown in fig. 2, the solar panel cleaning apparatus 10 in the 2 nd maintenance state has a configuration including: a small molded body 30 serving as an "apparatus main body" and having a cleaning mechanism 40; a 2 nd moving member 60 and a 3 rd moving member 70 as a "moving mechanism" for moving the small body 30; and a control unit (control device) 80 that controls the compact 30, the 2 nd moving member 60, and the 3 rd moving member 70. The small-sized body 30 is formed in a substantially rectangular parallelepiped shape having a size not covering the entire solar panel unit 1 in the inclination direction L. In this embodiment, the 3 rd moving member 70 and the control unit 55 are provided in the small body 30, and the 2 nd moving member 60 is provided outside the small body 30.

As shown in fig. 2, the small body 30 of the present embodiment uses the 4 th divided body 30D among the plurality of divided bodies 30A to 30D shown in fig. 3 as a single body. The small body 30 composed of the 4 th divided body 30D is provided with a cleaning mechanism divided part 40D which constitutes the cleaning mechanism 40 as a single body, and a 3 rd moving member 70 which moves the small body 30 in the oblique direction L. In this embodiment, when the 4 th divided body 30D is used in the 2 nd maintenance state, the shafts 51D and 52D and the travel wheel 53D provided in the 1 st moving member divided part 50D of the 4 th divided body 30D are detached in advance.

Specifically, the cleaning mechanism dividing section 40D constituting the cleaning mechanism 40 includes two left and right rotary brushes 41D, 42D extending in the oblique direction L, and rotary brush motors 43D, 44D for rotating the rotary brushes 41D, 42D. These configurations are the same as those in the 1 st maintenance state. These rotary brush motors 43D and 44D are configured to independently transmit power to the rotary brushes 41D and 42D under the control of the control unit 80.

As shown in fig. 6, the 3 rd moving member 70 has a pinion gear 72, the pinion gear 72 is engaged with a rack gear 71, and the rack gear 71 is formed to penetrate from the upper end to the lower end of the frame 61 along the oblique direction L at a substantially central position in the lateral direction of the frame 61 of the 2 nd moving member 60 described later, and a rack-and-pinion structure is formed by these. The pinion gear 72 is driven by a vertical movement motor 73 disposed in the 4 th divided body 30D, and the vertical movement motor 73 is driven in a state where the rack gear 71 is meshed with the pinion gear 72, so that the pinion gear 72 rotates in the vertical direction along the rack gear 71, and the 4 th divided body 30D moves vertically accordingly.

In the present embodiment, a brim portion 75 is disposed above the rack 71 (in the vertical direction with respect to the plate surface 3) so as to protrude laterally from the teeth of the rack 71, and the brim portion 75 is formed in an elongated shape so as to cover the entire surface in the oblique direction L in which the rack 71 is formed. The overhang-like portion 75 is pressed to prevent the pinion 72 from being displaced upward (in the vertical direction with respect to the plate surface 3), and the pinion 72 engaged with the rack 71 is prevented from being displaced upward (in the vertical direction with respect to the plate surface 3) and being out of engagement with the rack 71.

In this embodiment, a rail member 60 is disposed as the 2 nd moving means, and the compact 30 is mounted thereon and moved in the lateral direction (horizontal direction) P on the plate surface 3. As shown in fig. 2, the guide rail member 60 has two shafts 62 extending from an upper end (a rear side) to a lower end (a front side) in the inclination direction L, and a plurality of traveling wheels 63 are fixed to the shafts 62. Further, the movement motor 64 for transmitting power to the shaft 62 is disposed at a predetermined position, and by these configurations, the rail member 60 can reciprocate in the lateral direction P on the plate surface 3.

As shown in fig. 2, a guide roller 65 is provided at the upper end (back side) of the guide rail member 60. The guide roller 65 is provided to stably move the small-sized body 30 in the horizontal direction P of the solar panel unit 1, and is engaged with the upper side surface 1a of the solar panel unit 1. Further, the guide rollers 65 are formed by wheels facing the upper side surface 1a, and thus the small-sized body 30 can be moved in the horizontal direction P by the guide rollers 65.

The 4 th divided body 30D as the small body 30 is attached to the pinion gear 72 of the rail member 60, the up-down movement motor 73, and members which move up and down together with these members. Further, a control unit 80 for the 2 nd maintenance state is disposed at a lower end (front side) of the guide rail member 60, and the control unit 80 controls driving of the cleaning mechanism 40 and the 3 rd moving member 70 in the compact 30 and movement of the guide rail member 60 in the lateral direction P.

In the divided body 30D, as the structure of the cleaning mechanism divided part 40D, a shield brush (not shown) and a sprinkler pipe (not shown) as a "fluid supply pipe" may be provided together with the rotary brushes 41D and 42D. The frame 61 is mainly made of aluminum from the viewpoint of satisfying both the weight reduction and the strength.

Further, the rail member 60 of the present embodiment can be divided into two or more parts, and can be conveyed in a divided state during conveyance, and therefore, can be conveyed efficiently without limitation to a place. Further, since the sheets are transported in order and connected to each other even at the time of installation, the burden on the operator can be reduced.

In this way, the divided body 30D is mounted on the guide rail member 60 as a single body, and the divided body 30D is moved forward, backward, leftward and rightward by the horizontal moving means and the vertical moving means to perform cleaning, whereby the divided body can be moved in the 2 nd maintenance state.

Next, the operation of the 2 nd maintenance state of the present embodiment will be described.

When the solar panel cleaning device 10 of the present embodiment is installed in the solar panel unit 1, first, the divided rail members 60 are installed in the solar panel unit 1. Here, the guide roller 65 provided at the upper end (rear side) of the divided portion is engaged with the upper side surface 1a of the solar panel unit 1, and the other divided portion is connected to the lower side (front side) thereof, thereby completing the rail member 60.

Next, the 4 th divided body 30D is disposed on the rail member 60 and attached by a predetermined method, and the shafts 51D and 52D and the traveling wheel 53D of the 1 st moving member divided part 50D provided in the 4 th divided body 30D are detached in advance from the 4 th divided body 30D. In addition, a fluid supply pipe or the like is connected to a sprinkler pipe or the like, not shown, and is prepared.

Thereby, the 4 th divided body 30D and the rail member 60 are joined, and the assembly of the photovoltaic panel cleaning apparatus 10 in the 2 nd maintenance state is completed.

Then, the panel 3 is cleaned while moving the small-sized bodies 30 horizontally on the solar panel unit 1, for example, from the upper left to the upper right. After the small body 30 reaches the right end, the small body 30 is moved downward (toward the front) by an amount corresponding to the longitudinal length of the small body 30, and then moved horizontally from right to left. After the small body 30 reaches the left end, the small body 30 is further moved downward by the length in the longitudinal direction of the small body 30. This operation is repeated to sweep the board in a zigzag pattern up to the lower end of the board surface 3.

As described above, the solar panel cleaning device 10 according to the above embodiment can perform maintenance work with the device body in two states: a connected body 20 formed by connecting and integrating a plurality of divided bodies 30A to 30D, and a small body 30 formed by the divided bodies 30D less than the connected body 20. Therefore, the state of the apparatus main body can be selected according to the work environment, and the operator can select the most appropriate state to perform the maintenance work.

Further, according to the solar panel cleaning device 10 of the above-described embodiment, by more specifically defining the operation of the device main body in each of the 1 st maintenance state and the 2 nd maintenance state, the state of the device main body can be selected more appropriately according to the work environment, and the operator can further select the most appropriate state to perform the maintenance work.

Further, according to the solar panel cleaning device 10 of the above-described embodiment, the 1 st moving member 40, which is a relatively large device configuration used in the 1 st maintenance state, is formed in a state of being divided into the divided bodies 30A to 30D, so that it is possible to make the configuration usable only by connecting the divided bodies 30A to 30D to each other by an operator, and it is possible to reduce the burden on the operator in performing work.

In addition, according to the solar panel cleaning device 10 of the above-described embodiment, the small-sized body 30 is provided on the rail member 60 in the 2 nd maintenance state, so that the solar panel cleaning device 10 can be relatively easily installed.

Further, according to the solar panel cleaning device 10 of the above-described embodiment, by moving the small-sized body 30 in the direction of the rail member 60 in the 2 nd maintenance state by the rack 71 and the pinion 72, even when the inclination of the plate surface 3 is gentle or substantially horizontal, the movement in the direction of the rail member 60 can be reliably performed.

In the solar panel cleaning device 10 according to the above-described embodiment, the eaves 75 protruding from the teeth of the rack 71 are provided above the rack 71, so that when the small-sized body 30 is likely to float from the plate surface 3, for example, when the inclination is steep, the floating of the pinion 72 engaged with the rack 71 can be pressed, and the pinion 72 can be prevented from being disengaged from the engaged state with the rack 71. As a result, small body 30 can be prevented from coming off guide rail member 60, and maintenance work can be performed reliably.

The embodiments described above are described to facilitate understanding of the present invention, and do not limit the present invention.

For example, in the above-described embodiment, the guide rollers 21 and 65 move in the horizontal direction P while making the wheels abut on the upper side surface 1a of the solar panel unit 1, but the present invention is not limited to this, and the device main bodies 20 and 30 may be moved in the horizontal direction P using a crawler (caterpillar) or a member that slides with respect to the upper side surface 1a instead of the wheels.

In the above-described embodiment, the device main bodies 20 and 30 are held by the solar panel unit 1 by being caught on the upper side surface 1a of the solar panel unit 1 by the guide rollers 21 and 65, but the present invention is not limited to this, and for example, in the case where the installation angle of the solar panel 2 is gentle or horizontal, the guide rollers may be provided, and the device main body 20 and 30 can be moved on the panel surface 3 basically only by the linear movement capability of the moving member of the cleaning device main body 30. Alternatively, the device body may be held by the solar panel unit 1 using another structure.

In the above-described embodiment, the moving mechanism for moving the cleaning mechanism 40 as the maintenance mechanism is provided with the traveling wheels such as tires, but the present invention is not limited to this, and instead of the traveling wheels, crawler belts, sliding members, and the like may be provided to travel on the solar panel 2.

In the above-described embodiment, the 4 th divided body 30D is used as the small molded body 30, but the present invention is not limited to this, and another divided body may be used or a structure in which divided body is used can be selected. The small body is not limited to a structure composed of 1 divided body, and may be a small body in which two or 3 divided bodies are combined and moved in a meandering manner.

The configurations of the cleaning mechanism, the drive mechanism, the control device, and the like are not limited to the above-described embodiments, and appropriate configurations may be adopted.

For example, the structure of the coupling portion of the divided body is not limited to the structure in which the protruding portion and the retracted portion are provided, and the structure in which the coupling pin and the insertion hole are provided, and the coupling may be performed by other methods.

In the above-described embodiment, the cleaning is performed using water, but a liquid other than water or a gas such as air may be used. The fluid may be supplied by a mist spray method, a pulse spray method, a method of flowing down the fluid, or any other method.

In the above-described embodiment, the solar panel unit 1 has a structure in which the gap S is provided between the solar panels 2 adjacent to each other in the horizontal direction P, but the gap S is not provided between the solar panels 2 adjacent to each other in the oblique direction L. For example, the solar panel unit 1 may be used in which there is no gap between the solar panels adjacent in the horizontal direction P and a gap is provided between the solar panels adjacent in the oblique direction L. Further, the solar panel unit 1 may be used in which there is no gap between the solar panels adjacent to each other in the horizontal direction P and between the solar panels adjacent to each other in the oblique direction L.

In the above-described embodiment, the travel wheels 53 are driven by the driving force of 1 movement motor 54, but the present invention is not limited thereto. For example, the cleaning device main body 30 may be configured to transmit independent driving force to all the travel wheels.

In the above-described embodiment, when the divided body 30D is used as the small body 30, the moving mechanism attached in advance is detached and the moving mechanism of the rail member 60 is used, but the present invention is not limited to this, and the moving mechanism of the small body may be configured by using all or part of the moving mechanism attached in advance.

In the above-described embodiment, the moving mechanism using the guide rail member 60 is used as the moving mechanism in the 2 nd maintenance state, but the moving mechanism is not limited to this, and a mechanism that moves the small-sized body while the small-sized body moves by itself and meanders without using the guide rail member, or a mechanism that moves the small-sized body while being supported at a predetermined position by using a support member other than the guide rail member may be used. The movement mode is not limited to the meandering mode, and may be a mode in which the movement trajectory travels.

In the above-described embodiment, the rotary brushes 41A to 41D and 42A to 42D are configured to be independently driven by the brush motors 43A to 43D and 44A to 44D in the respective divided bodies 30A to 30D in the 1 st maintenance state, but the configuration is not limited to this. For example, when the divided bodies 30A to 30D are connected, the rotating brushes in the same row are connected and may rotate in conjunction with each other. In this case, the number of brush motors for driving the rotary brushes in the same row may be 1. The shafts of the rotating brushes of the segments 30A to 30D may be coupled to each other at the same time as the coupling of the segments 30A to 30D by a primary contact type connector or the like.

In the above-described embodiment, the case where the present invention is applied to the photovoltaic panel cleaning apparatus 10 has been described as an example of the photovoltaic panel maintenance apparatus, but the present invention is not limited to this. For example, the present invention can be applied to a solar panel coating apparatus in which a coating agent is applied to a surface of a solar panel to form an antireflection film for the purpose of improving or recovering power generation, and the present invention can also be applied to a solar panel coating apparatus having a function of spreading the applied coating agent by a squeegee or the like.

The present invention may be applied not only to a cleaning device of a type for cleaning with a brush and water as described above, but also to a cleaning device of another structure, for example, a cleaning device of a type for cleaning by blowing off dust or the like on a board surface with a blowing device, or a cleaning device of a type for cleaning or wiping a board surface without using water by using a brush or a squeegee to remove dust or the like. In addition, the present invention can be applied to a solar panel cleaning device that performs cleaning using a brush or a squeegee and cleaning using a blowing device simultaneously in parallel.
