[0042] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0043] Hereinafter, the terms "first" and "second" are only used for description purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more features.

[0044] In the photovoltaic industry, the semi-automatic intelligent cleaning robot is a cleaning robot that needs to be manually transported. During the cleaning process, it needs to be manually transported to different photovoltaic module strings of the photovoltaic module, so as to realize the cleaning of multiple rows of photovoltaic module strings by the semi-automatic intelligent cleaning robot.

[0045] After the semi-automatic intelligent cleaning robot moves to the reversing position on the photovoltaic module string, the semi-automatic intelligent cleaning robot will trigger reversing information or stop information at the reversing position. When the stop information is triggered, the transport worker will transport the semi-automatic intelligent cleaning robot to the next photovoltaic module string, so as to clean the photovoltaic module string. At present, reversing positions are arranged on all photovoltaic module strings.

[0046] However, during the working process of a semi-automatic intelligent cleaning robot, it only cleans one row of photovoltaic module strings at the same time, and the reversing positions on the photovoltaic module strings of other rows do not play a role except for the working row of photovoltaic module strings. Therefore, the sensing baffle of the reversing position on the photovoltaic module string of the other row is idle, causing resource waste.

[0047] Based on this, the embodiment of the present application discloses a reversing assembly, which comprises a reversing device. When the cleaning robot changes the photovoltaic module string to be cleaned, the sensing baffle can be removed and installed on the photovoltaic module string to be cleaned by the cleaning robot, that is, the sensing baffle changes position with the cleaning robot. Therefore, it is not necessary to arrange sensing baffles on all photovoltaic module strings, which reduces the number of sensing baffles, thereby solving the problem of idle sensing baffles on the photovoltaic module string, and further solving the problem of resource waste.

[0048] As shown in the figure, Figures 1 to 3 The photovoltaic cleaning system disclosed by the embodiment of the present application comprises a photovoltaic module 100, a cleaning robot 200 and a reversing assembly. The reversing assembly comprises a reversing device.

[0049] The photovoltaic module 100 is a cleaning structure, and the specific structure and arrangement of the photovoltaic module 100 are not limited.

[0050] The cleaning robot 200 is a structure for cleaning the photovoltaic module 100, and the specific structure and type of the cleaning robot 200 can be selected according to different needs, and the application does not specifically limit. The cleaning robot 200 in the application file is provided with a sensor 201. The type of the sensor 201 can be set according to different needs, and all are within the protection scope.

[0051] The reversing device 300 is detachably mounted on the photovoltaic module 100. During the cleaning process of the cleaning robot 200, when the sensor 201 of the cleaning robot 200 is opposite to the reversing device 300, that is, the cleaning robot 200 detects the reversing device 300, the cleaning robot 200 stops, and the operator can move the cleaning robot 200 to another photovoltaic module 100 and move the reversing device 300 to the corresponding photovoltaic module 100.

[0052] It should be noted that the reversing device 300 can also be used to indicate the cleaning robot 200 to reverse to ensure the cleaning degree. Therefore, in some embodiments, the reversing device 300 can control the cleaning robot 200 to reverse when detecting the cleaning robot 200 for the first time, and control the cleaning robot 200 to stop working when detecting the cleaning robot 200 for the second time.

[0053] The sensing baffle 301 of the embodiment of the application is detachably connected with the photovoltaic module 100 through the clamping assembly, so that the sensing baffle 301 can be installed on different photovoltaic modules 100 as needed to realize the replacement of the sensing baffle 301 with the cleaning robot 200, so that the sensing baffle 301 does not need to be arranged on all photovoltaic strings, reducing the number of sensing baffles 301, thereby solving the problem of idle sensing baffles 301 on the photovoltaic string, and further solving the problem of resource waste.

[0054] In some embodiments, the reversing device 300 is bonded or clamped with the photovoltaic module 100, and as long as the mode of detachable connection of the reversing device 300 and the photovoltaic module 100 can be within the protection scope.

[0055] As shown in Figure 4 and Figure 5 The reversing device 300 includes a sensing baffle 301 and a clamping assembly. The clamping assembly includes an upper clamping part 302, a lower clamping part 303, a tensioning device 304, and a rotating shaft 305.

[0056] The upper clamping part 302 and the lower clamping part 303 are hinged through the rotating shaft 305, and a clamping part capable of clamping the photovoltaic module 100 is formed between the upper clamping part 302 and the lower clamping part 303. The sensing baffle 301 is connected with the clamping assembly, and has a detection position of the sensor 201 of the cleaning robot 200. When the sensor 201 of the cleaning robot 200 is opposite to the detection position of the sensing baffle 301, the cleaning robot 200 is reversed or stopped.

[0057] Optionally, the detection position of the sensing baffle 301 is a baffle. When the sensor 201 detects the baffle, a signal is sent.

[0058] In some embodiments, the sensing baffle 301 described above includes the baffle 3011 and the first connecting plate 3012. The upper clamping part 302 includes the upper clamping plate 3021 and the second connecting plate 3022. The lower clamping part 303 includes the hinged plate 3031 and the lower clamping plate 3032.

[0059] The baffle 3011 and the first connecting plate 3012 include but are not limited to vertical arrangement, and are connected as an L-shaped structure. The baffle 3011 is arranged towards or away from the photovoltaic module 100. Optionally, the baffle 3011 is arranged parallel to the photovoltaic module 100.

[0060] When the baffle 3011 is opposite to the sensor 201, the cleaning robot 200 is reversed or stopped. It can be understood that the baffle 3011 is configured as a trigger of the sensor 201 of the cleaning robot 200.

[0061] The second connecting plate 3022 is connected with the first connecting plate 3012. Optionally, the first connecting plate 3012 is adjustable in the height direction (the height direction is the thickness direction of the photovoltaic module 100) relative to the second connecting plate 3022, so that the distance of the baffle 3011 relative to the photovoltaic module 100 is adjustable.

[0062] Optionally, the first connecting plate 3012 and the second connecting plate 3022 are connected through a threaded connecting piece, and at least one of the first connecting plate 3012 and the second connecting plate 3022 is provided with a waist-shaped hole, and the waist-shaped hole extends in the height direction.

[0063] It should be noted that the sensing baffle 301 and the clamping assembly are connected through the waist-shaped hole, so that the sensing baffle 301 can be adjusted in the height direction to adapt to the height difference between the sensor 201 and the photovoltaic module 100 caused by the installation error of the photovoltaic support of different power stations or the rigidity of the photovoltaic module 100 itself.

[0064] For example, Figure 5As shown, the second connecting plate 3022 is provided with a first waist-shaped hole 30221 extending along the height direction, and the first connecting plate 3012 has a through hole. During assembly of the first connecting plate 3012 and the second connecting plate 3022, the through hole of the first connecting plate 3012 is opposite to the first waist-shaped hole 30221 of the second connecting plate 3022, and the height of the first connecting plate 3012 relative to the second connecting plate 3022 is adjusted by adjusting the position of the through hole opposite to the first waist-shaped hole 30221.

[0065] One end of the upper clamping plate 3021 is connected with the second connecting plate 3022, and the other end of the upper clamping plate 3021 is rotatably connected with the hinged plate 3031 through the rotating shaft 305. Optionally, in some embodiments, the rotating shaft 305 includes a rotating rod 3051 and a locking pin 3052, and the locking pin 3052 is inserted into the rotating rod 3051 to form a structure for rotatably connecting the hinged plate 3031 with the upper clamping plate 3021.

[0066] In some embodiments, the rotating shaft 305 is sleeved with a tensioning device 304, and the tensioning device 304 is used to form a clamping force for clamping the photovoltaic module 100 between the hinged plate 3031 and the upper clamping plate 3021.

[0067] The tensioning device 304 includes but is not limited to a torsion spring, and the strength and number of the torsion spring can be set according to different needs and are within the protection scope.

[0068] In optional embodiments, the upper clamping plate 3021 and the second connecting plate 3022 are arranged along a first direction, and the hinged plate 3031 and the lower clamping plate 3032 are arranged along the first direction. The first direction herein is a direction perpendicular to one side frame of the photovoltaic module 100 in a plane where the photovoltaic module 100 is located.

[0069] The lower clamping plate 3032 is inclined relative to the hinged plate 3031. Specifically, the distance from one end of the lower clamping plate 3032 close to the hinged plate 3031 to the hinged plate 3031 along the height direction is greater than the distance from the other end of the lower clamping plate 3032 away from the hinged plate 3031 to the hinged plate 3031 along the height direction.

[0070] It should be noted that the inclined arrangement of the lower clamping plate 3032 in the embodiments of the present application can make the end of the lower clamping plate 3032 away from the hinged plate 3031 have a greater clamping force, so as to improve the stability of the reversing device 300.

[0071] As shown, Figures 6 to 9 By changing the opening degree between the lower clamping plate 3032 and the upper clamping plate 3021, i.e., the torsion spring is under different torsion force, the clamping of photovoltaic modules 100 with different thicknesses can be realized.

[0072] It should be noted that by changing the clamping position of the hinge plate 3031 and the upper clamping plate 3021, the opening degree of the upper clamping plate 3021 and the lower clamping plate 3032 can be changed.

[0073] As shown in Figure 6 The baffle 3011 is arranged relative to the grid pattern on the surface of the photovoltaic module 100, the frame of the photovoltaic module 100, the support purlin and other string features.

[0074] Correspondingly, the sensor 201 of the cleaning robot 200 is arranged relative to the grid pattern on the surface of the photovoltaic module 100, the frame of the photovoltaic module 100, the support purlin and other string features.

[0075] As shown in Figure 5 and Figure 6 The upper clamping plate 3021 is provided with an observation hole 30211 at one end close to the first connecting plate 3012, and the observation hole 30211 is a through hole penetrating through the first connecting plate 3012 in the thickness direction (the same as the height direction).

[0076] By setting the observation hole 30211, the grid pattern of the photovoltaic module 100 can be seen, and the clamping position of the reversing device 300 can be quickly confirmed after the reversing device 300 is reversed.

[0077] The above-mentioned reversing device 300 in the reversing assembly is arranged towards the photovoltaic module 100, which can be understood as that the baffle 3011 of the reversing device 300 is arranged opposite to the photovoltaic module 100.

[0078] In other optional embodiments, as shown in Figure 10 and Figure 11 The reversing assembly in the photovoltaic cleaning system includes the reversing device 300 and the reversing support 400.

[0079] Among them, the reversing device 300 can be detachably connected with the photovoltaic module 100, and the reversing device 300 is used to prompt the cleaning robot 200 to change position. Specifically, the cleaning robot 200 detects the reversing device 300 during cleaning, and the cleaning robot 200 stops. The operator can move the cleaning robot 200 to another photovoltaic module 100, and move the reversing device 300 to the corresponding photovoltaic module 100. And the reversing device 300 can also be used to indicate the cleaning robot 200 to reverse.

[0080] Optionally, the structure of the reversing device 300 can refer to the structure of the reversing device 300 disclosed in the above-mentioned embodiments.

[0081] The reversing support 400 is used to be detachably connected with the photovoltaic module 100, and is used to support and limit the movement of the cleaning robot 200, so as to prevent the cleaning robot 200 from falling off the photovoltaic module 100.

[0082] The reversing support 400 comprises a first reversing support 401 and a second reversing support 402, wherein the first reversing support 401 is arranged at the first end of the photovoltaic module 100, the second reversing support 402 is arranged at the second end of the photovoltaic module 100, and the connecting direction of the first end and the second end is the installation direction of the cleaning robot 200 and is perpendicular to the walking direction of the cleaning robot 200.

[0083] The first reversing support 401 and the second reversing support 402 can provide support for the cleaning robot 200 and can limit the walking position of the cleaning robot 200 to prevent the cleaning robot 200 from falling off the photovoltaic module 100.

[0084] Optionally, the baffle 3011 of the reversing device 300 extends away from the photovoltaic module 100, and the first reversing support 401 and the second reversing support 402 extend away from the photovoltaic module 100,

[0085] It should be noted that the baffle 3011 of the reversing device 300 extends away from the photovoltaic module 100, which can increase the cleaning range of the cleaning robot 200 on the photovoltaic module 100 and reduce the cleaning dead angle when the baffle 3011 is opposite to the photovoltaic module 100, which is conducive to improving the cleanliness of cleaning the photovoltaic module 100.

[0086] However, the baffle 3011 of the reversing device 300 extends away from the photovoltaic module 100, so that the cleaning robot 200 has a position to escape at the first end and the second end of the photovoltaic module 100, and thus there is a risk that the cleaning robot 200 will fall off the photovoltaic module 100. The reversing support 400 provided can support the position of the cleaning robot 200 escaping from the photovoltaic module 100, prevent the cleaning robot 200 from failing to connect at the connecting position of the first end and the second end of the photovoltaic module 100, and prevent the cleaning robot 200 from falling off the photovoltaic module 100 when moving to the position of the baffle 3011.

[0087] In addition, the reversing support 400 can also limit the walking of the cleaning robot 200. When the cleaning robot 200 moves to be opposite to the baffle 3011, the cleaning robot 200 abuts against the reversing support 400, thereby limiting the cleaning robot 200, and avoiding the problem of the cleaning robot 200 continuing to walk and falling.

[0088] As shown in Figure 12 and Figure 13 The reversing device 300 comprises an induction baffle 301 and a clamping assembly, wherein the clamping assembly comprises an upper clamping part 302, a lower clamping part 303, a tensioning device 304, a rotating shaft 305 and a buffer pad 306.

[0089] The induction baffle 301 comprises a baffle 3011 and a first connecting plate 3012, the upper clamping part 302 comprises an upper clamping plate 3021 and a second connecting plate 3022, and the lower clamping part 303 comprises a hinged plate 3031 and a lower clamping plate 3032.

[0090] The structures of the induction baffle 301, the upper clamping part 302, the lower clamping part 303, the tensioning device 304 and the rotating shaft 305 can refer to the descriptions of Figure 4 and Figure 5 and will not be described herein.

[0091] It should be noted that: Figure 12 and Figure 13 the arrangement directions of the hinged plate 3031 and the lower clamping plate 3032 are opposite to those in Figure 4 and Figure 5 , that is, Figure 12 the hinged plate 3031 in the present application is close to the second connecting plate 3022, so that the hinged position of the hinged plate 3031 and the upper clamping plate 3021 is close to the second connecting plate 3022, and further, the end of the upper clamping plate 3021 away from the second connecting plate 3022 is opposite to the lower clamping plate 3032, forming a clamping part for clamping the photovoltaic module 100.

[0092] By using the reversing device 300, Figure 12 and Figure 13 , the baffle 3011 of the reversing device 300 can extend in a direction away from the photovoltaic module 100, so as to increase the stroke of the cleaning robot 200, thereby increasing the cleaning range of the cleaning robot 200 and reducing the health dead angle of the photovoltaic module 100.

[0093] It should be noted that, as shown in Figure 15 , a buffer pad 306 can be arranged at the position where the upper clamping plate 3021 is opposite to the lower clamping plate 3032, so as to reduce the abrasion of the photovoltaic module 100 by the upper clamping plate 3021 during clamping. The buffer pad 306 comprises but is not limited to a nylon pad, and can also be other elastic structural members.

[0094] In some embodiments, no observation hole is arranged on the upper clamping plate 3021, and an indication mark 30212 is arranged at the position of the upper clamping plate 3021 facing the photovoltaic module 100, so as to quickly confirm the installation position of the reversing device 300 on the photovoltaic module 100 by the indication mark 30212 being opposite to the grid lines on the surface of the photovoltaic module 100, the frame of the photovoltaic module 100, the support purlin and other string features.

[0095] Optionally, the indication mark 30212 comprises but is not limited to an indication arrow.

[0096] The first reversing support 401 and the second reversing support 402 disclosed by the embodiments of the present application have the same structure and are symmetrically arranged with respect to the center position of the first end and the second end of the photovoltaic module 100.

[0097] The structure of the first reversing support 401 will be described below in combination with the structure of the second reversing support 402. Figures 16 to 18 The structure of the first reversing support 401 will be described below in combination with the structure of the second reversing support 402.

[0098] As shown in Figure 16 and Figure 17 , the first reversing support 401 comprises an assembly seat 4011, a walking beam 4012, a limiting beam 4013 and a limiting buckle 4014.

[0099] The assembly seat 4011 is used to be connected to the top corner of the first end of the photovoltaic module 100 through the limiting buckle 4014. The assembly seat 4011 is an L-shaped corner structure which is adapted to the top corner of the photovoltaic module 100. The L-shaped corner structure is provided with a stop edge on one side along the thickness direction of the photovoltaic module 100 and is provided with the limiting buckle 4014 on the other side. The top corner of the photovoltaic module 100 is clamped in the assembly seat 4011 by using the stop edge and the limiting buckle 4014.

[0100] Optionally, the assembly seat 4011 comprises a bottom surface 40111, a stop edge 40112 and a side edge 40113. The bottom surface 40111 is provided with the limiting buckle 4014. The stop edge 40112 is opposite to the bottom surface 40111 along the thickness direction of the assembly seat 4011. The side edge 40113 connects the bottom surface 40111 and the stop edge 40112 and is used to be fitted to the frame of the photovoltaic module 100.

[0101] One end of the walking beam 4012 is connected to the assembly seat 4011, and the walking beam 4012 is arranged along the walking direction of the cleaning robot 200. It can be understood that the walking beam 4012 is parallel and collinearly arranged with the frame of the first end of the photovoltaic module 100 which extends along the walking direction of the cleaning robot 200, so that the frame is extended in the walking direction and is used to support the cleaning robot 200.

[0102] The limiting beam 4013 is connected to the other end of the walking beam 4012. The limiting beam 4013 intersects the walking beam 4012 and extends away from the second end of the photovoltaic module 100. For the second reversing support 402, the limiting beam 4013 of the second reversing support 402 extends away from the first end of the photovoltaic module 100.

[0103] The limiting buckle 4014 comprises a limiting block 40141, a spring 40142, a cover 40143, a connecting piece 40144 and a guide handle 40145.

[0104] The limiting block 40141 has an inclined surface at the position extending into the assembly seat 4011, and the inclined surface is located at the side of the limiting block 40141 away from the side edge 40113. The side of the limiting block 40141 towards the side edge 40113 is a plane parallel to the corresponding side edge 40113. It can be understood that the side of the limiting block 40141 towards the side edge 40113 is a vertical plane along the first direction, and the inclined surface gradually approaches the vertical plane along the direction from the bottom surface 40111 to the blocking edge 40112, so that the limiting block 40141 is formed as a wedge-shaped block.

[0105] The cover 40143 is detachably connected to the side of the bottom surface 40111 of the assembly seat 4011 away from the blocking edge 40112, and the connection manner includes but is not limited to using a connecting piece 40144, and the connecting piece 40144 includes but is not limited to a bolt.

[0106] The guide handle 40145 is inserted into the cover 40143 from the end of the cover 40143 away from the assembly seat 4011, and is limitingly connected or threadedly connected with the cover 40143. One end of the guide handle 40145 has a handle, and the other end is connected with the limiting block 40141 through the spring 40142. It can be understood that the spring 40142 is sleeved on the guide rod of the guide handle 40145, and one end is abuttingly connected with the handle, and the other end is connected with the limiting block 40141.

[0107] It should be noted that in the process of assembling the photovoltaic module 100 into the assembly seat 4011, the top corner of the photovoltaic module 100 is continuously inserted between the blocking edge 40112 and the bottom surface 40111, and the frame of the photovoltaic module 100 is continuously pressed downward under the guidance of the inclined surface, so that the limiting block 40141 moves towards the guide handle 40145 and continuously compresses the spring 40142, until the photovoltaic module 100 enters the assembly seat 4011; after the photovoltaic module 100 enters the assembly seat 4011, the frame of the photovoltaic module 100 is separated from the limiting block 40141, and under the action of the spring 40142, the limiting block 40141 extends into the assembly seat 4011 and limits the photovoltaic module 100 by using the plane of the limiting block 40141.

[0108] When it is needed to separate the photovoltaic module 100 from the assembly seat 4011, the operator can pull the guide handle 40145 downward to separate the guide handle 40145 from the cover 40143, and through the spring 40142, the limiting block 40141 is separated from the assembly seat 4011 to release the photovoltaic module 100.

[0109] In some embodiments, the limiting buckles 4014 are two, and the inclined surfaces of the limiting blocks 40141 of the two limiting buckles 4014 are arranged vertically and limit two intersecting side frames in the frame of the photovoltaic module 100.

[0112] In some embodiments, the windproof structure 4015 includes a binding rope 40151 and a lock 40152.

[0113] The two ends of the binding rope 40151 are both inserted through the walking beam 4012, so that a closed annular space is formed between the binding rope 40151 and the walking beam 4012. The end of the binding rope 40151 can be limited on the walking beam 4012 by the lock 40152.

[0114] Optionally, after the binding rope 40151 is inserted through the walking beam 4012 along the thickness direction of the photovoltaic module 100, the lock 40152 is locked with the binding rope 40151, and the binding rope 40151 is fixed with the walking beam 4012 by the lock 40152 abutting against the walking beam 4012. Specifically, the lock 40152 can abut against the side of the walking beam 4012 away from the walking of the cleaning robot 200.

[0115] The lock 40152 includes a lock body and a fastener. The lock body is inserted through the binding rope 40151, and the fastener can be inserted into the lock body and abut against the binding rope 40151 to fix the binding rope 40151 in the lock body.
