Detailed Implementation

[0022] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0023] This application aims to address at least one of the technical problems existing in the related art. To this end, this application proposes a photovoltaic system that can reduce the amount of engineering materials and construction and installation work on site while maintaining the load-bearing capacity of the shutdown position.

[0024] The following is for reference. Figures 1-10 A photovoltaic system 1 according to an embodiment of this application is described.

[0025] like Figure 1 As shown, Figure 1 This is one of the structural schematic diagrams of the photovoltaic system 1 provided in the embodiments of this application. The photovoltaic system 1 includes: a photovoltaic support 10; a plurality of photovoltaic rows 20, which are installed on the photovoltaic support 10 at intervals along a first direction X; at least one connecting bridge 30, which connects adjacent photovoltaic rows 20, and the at least one connecting bridge 30 forms a parking position 40 for parking a photovoltaic cleaning robot 70.

[0026] In this embodiment, such as Figure 1 and Figure 2 As shown, Figure 1 This is one of the structural schematic diagrams of the photovoltaic system 1 provided in the embodiments of this application. Figure 2This is a second schematic diagram of the structure of the photovoltaic system 1 provided in the embodiments of this application. The photovoltaic system 1 may include a photovoltaic support 10, a plurality of photovoltaic rows 20 and at least one connecting bridge 30, wherein the first direction X is the length direction of the photovoltaic support 10, the plurality of photovoltaic rows 20 are installed on the photovoltaic support 10 at intervals along the first direction X, and adjacent photovoltaic rows 20 are connected by the connecting bridge 30. The photovoltaic row 20 may include a plurality of photovoltaic modules distributed along the first direction X, and the number of photovoltaic modules in the same photovoltaic row 20 is not limited.

[0027] like Figure 3 As shown, Figure 3 yes Figure 2 A partial enlarged view at point A. The photovoltaic support 10 may include a main shaft 130 and multiple columns 120. The photovoltaic support 10 drives multiple photovoltaic arrays 20 to rotate via the main shaft 130. The multiple photovoltaic arrays 20 installed on the same main shaft 130 have the same rotation amplitude. The multiple columns 120 are spaced apart along the first direction X and installed in the ground or other installation environments. The main shaft 130 extends along the first direction X and is installed at the top of the columns 120. The photovoltaic arrays 20 are installed on the main shaft 130 via purlins 110, and the connecting bridges 30 between adjacent photovoltaic arrays 20 correspond one-to-one with the columns 120.

[0028] In addition, such as Figure 2 and Figure 4 As shown, Figure 2 This is the second schematic diagram of the structure of the photovoltaic system 1 provided in the embodiments of this application. Figure 4 This is the third structural schematic diagram of the photovoltaic system 1 provided in this application embodiment. Connecting bridges 30 connect adjacent photovoltaic rows 20. At least one connecting bridge 30 forms a parking position 40 for parking the photovoltaic cleaning robot 70. The parking position 40 is divided into an emergency parking position 40 and a regular parking position 40. During the cleaning process of the photovoltaic cleaning robot 70, when severe weather such as strong winds prevents the photovoltaic cleaning robot 70 from working, the photovoltaic cleaning robot 70 moves to the nearest emergency parking position 40 to achieve emergency avoidance. After each cleaning cycle, the photovoltaic cleaning robot 70 returns to the regular parking position 40.

[0029] like Figure 5 and Figure 6 As shown, Figure 5 This is the fourth structural schematic diagram of the photovoltaic system 1 provided in the embodiments of this application. Figure 6This is the fifth structural schematic diagram of the photovoltaic system 1 provided in the embodiments of this application. The photovoltaic system 1 also includes reversing positions. The photovoltaic bracket 10 is provided with reversing positions at both ends along the first direction X. The reversing positions are the positions where the photovoltaic cleaning robot 70 changes its moving direction after completing the cleaning of multiple photovoltaic modules on a photovoltaic bracket 10. After the photovoltaic cleaning robot 70 reaches the end of the photovoltaic bracket 10, it performs a reversing operation through the reversing positions. At the same time, the top of the photovoltaic cleaning robot 70 is provided with a photovoltaic panel for charging. The reversing positions can also have the function of cleaning the photovoltaic panels of the photovoltaic cleaning robot 70.

[0030] It should be noted that one photovoltaic bracket 10 is equipped with one photovoltaic cleaning robot 70. Figure 1 The photovoltaic cleaning robot 70 in the image is only used to illustrate the possible stopping positions of the photovoltaic cleaning robot 70, for example... Figure 2 The photovoltaic cleaning robot 70 is located at emergency stop position 40. Figure 4 The photovoltaic cleaning robot 70 is located in the regular parking position 40. Figure 5 and Figure 6 The photovoltaic cleaning robot 70 is located in the reversing position.

[0031] In related technologies, the reversing position and stopping position of photovoltaic cleaning robots are mostly set separately on both sides of the flat single-axis bracket. However, the stopping position requires additional pile foundation to be laid during on-site installation, which increases the amount of on-site engineering materials and the workload of construction and installation. In addition, photovoltaic cleaning robots usually identify the stopping position through a sensor switch. When the sensor switch malfunctions or the sensor switch fails due to the bending of the lower end of the photovoltaic module, it is easy to fail to identify the stopping position, which indicates room for improvement.

[0032] This application sets the stopping position 40 on the connecting cable tray 30 and sets the reversing position at both ends of the photovoltaic bracket 10. The connecting cable tray 30 corresponds to the column 120 of the photovoltaic bracket 10. While maintaining the load-bearing capacity of the stopping position 40, it helps to reduce the amount of engineering materials and the workload of construction and installation on site. At the same time, this application sets a sensing structure 410 on the stopping position 40, and the installation position of the sensing structure 410 corresponding to at least one stopping position 40 is different from that of the sensing structure 410 corresponding to other stopping positions 40, which helps the photovoltaic cleaning robot 70 to accurately identify the stopping position 40.

[0033] According to the photovoltaic system 1 provided in the embodiments of this application, by setting the stop position 40 on the connecting cable tray 30, the amount of engineering materials and the workload of construction and installation on site can be reduced while maintaining the load-bearing capacity of the stop position 40.

[0034] In some embodiments, such as Figure 3 As shown, Figure 3 yes Figure 2A partial enlarged view at point A. The connecting cable tray 30 includes a connecting section 310, a fixing section 320, and a cable tray connector 330. The fixing section 320 is installed on the purlin 110 of the photovoltaic support 10. The connecting section 310 is connected to the fixing section 320 through the cable tray connector 330. The connecting section 310 includes a first part 311 and a second part 312. The first part 311 forms a stop position 40, and the second part 312 protrudes upward.

[0035] In this embodiment, the first direction X is the length direction of the photovoltaic support 10, the second direction Y is the width direction of the photovoltaic support 10, and the connecting bridge 30 includes two connecting sections 310, two fixing sections 320 and four bridge connectors 330. The connecting sections 310 extend along the first direction X and are spaced apart along the second direction Y. The fixing sections 320 extend along the second direction Y and are spaced apart along the first direction X. The fixing sections 320 are installed on the purlins 110 of the photovoltaic support 10, and the ends of the connecting sections 310 and the ends of the fixing sections 320 are connected by the bridge connectors 330 to form a rectangular connecting bridge 30.

[0036] In addition, the connecting section 310 includes a first part 311 and a second part 312. The first part 311 is arranged horizontally to form a stopping position 40, and the second part 312 is arched upward. The first part 311 and the second part 312 of the connecting section 310 are respectively distributed at intervals along the second direction Y. When the photovoltaic cleaning robot 70 is located at the stopping position 40, the two ends of the photovoltaic cleaning robot 70 are respectively located at the first part 311 of the connecting section 310 which is spaced apart along the second direction Y.

[0037] It should be noted that the column 120 and the connecting bridge 30 are vertically opposite each other, and the part where the main shaft 130 is connected to the column 120 is not linear. It is higher than other parts of the main shaft 130 and protrudes from the upper surface of the photovoltaic module. For example, a motor can be installed at the top of the column 120, and the output end of the motor is poweredly coupled to the main shaft 130. The motor is used to drive the main shaft 130 to rotate, and the column 120 can serve as a rotation support part of the main shaft 130.

[0038] The second part 312 of the connecting section 310 arches upward to facilitate the passage of the photovoltaic cleaning robot 70. When the photovoltaic cleaning robot 70 is located in the second part 312 of the connecting section 310, the height of the photovoltaic cleaning robot 70 is higher than that of the column 120, thereby reducing the interference of the column 120 on the photovoltaic cleaning robot 70.

[0039] Understandably, the upward arching of at least part of the connecting cable tray 30 helps to reduce the interference of the column 120 with the photovoltaic cleaning robot 70.

[0040] In some embodiments, such as Figure 3 As shown, Figure 3yes Figure 2 A partial enlarged view of point A. The connecting bridge 30 is equipped with a sensing structure 410, which is used to position the photovoltaic cleaning robot 70. When the photovoltaic cleaning robot 70 is in the parking position 40, the sensing structure 410 and the projection of the photovoltaic cleaning robot 70 along the second direction Y at least partially coincide, and the second direction Y intersects with the first direction X.

[0041] In this embodiment, the first direction X is the length direction of the photovoltaic bracket 10, and the second direction Y is the width direction of the photovoltaic bracket 10. The bottom side of the connecting bridge 30 is provided with a sensing structure 410. The sensing structure 410 is located at the stop position 40, and the installation positions of the sensing structure 410 at the emergency stop position 40 and the normal stop position 40 are different. When the photovoltaic cleaning robot 70 is located at the stop position 40, the photovoltaic cleaning robot 70 determines whether the stop position 40 is the emergency stop position 40 or the normal stop position 40 by recognizing the position of the sensing structure 410.

[0042] When the photovoltaic cleaning robot 70 is located at the parking position 40, the photovoltaic cleaning robot 70 crosses the connecting bridge 30 along the second direction Y. The projection of the sensing structure 410 and the photovoltaic cleaning robot 70 along the second direction Y at least partially overlaps. The photovoltaic cleaning robot 70 determines the installation position of the sensing structure 410 by measuring the distance between itself and the sensing structure 410 along the second direction Y, and then determines the parking position 40.

[0043] In some embodiments, such as Figure 7 As shown, Figure 7 This is a schematic diagram of the structure of the photovoltaic support 10 of the photovoltaic system 1 provided in this application embodiment. There are multiple parking positions 40, and the installation position of the sensing structure 410 corresponding to at least one of the multiple parking positions 40 is different from the installation position of the sensing structure 410 corresponding to the other parking positions 40.

[0044] In this embodiment, the parking position 40 can be divided into an emergency parking position 40 and a regular parking position 40. The emergency parking position 40 is used to park the photovoltaic cleaning robot 70 in case of an emergency, while the regular parking position 40 is used to park the photovoltaic cleaning robot 70 after it has finished cleaning.

[0045] The installation position of the sensing structure 410 corresponding to at least one of the multiple parking positions 40 is different from the installation position of the sensing structure 410 corresponding to the other parking positions 40. In other words, at least one of the multiple parking positions 40 is a regular parking position 40, and the other parking positions 40 are all emergency parking positions 40. The installation positions of the sensing structures 410 corresponding to the regular parking positions 40 and the emergency parking positions 40 are different. The photovoltaic cleaning robot 70 determines the type of parking position 40 by detecting the installation position of the sensing structure 410.

[0046] It is understandable that the installation position of the sensing structure 410 corresponding to at least one parking position 40 is different from that of the sensing structure 410 corresponding to other parking positions 40, which helps the photovoltaic cleaning robot 70 to accurately identify the parking position 40.

[0047] In some embodiments, such as Figure 7 As shown, Figure 7 This is a schematic diagram of the photovoltaic support 10 of the photovoltaic system 1 provided in this application embodiment. The induction structure 410 has various installation positions, including but not limited to: Example 1: The sensing structure 410 is installed on the fixed section 320.

[0048] In this embodiment, the fixed segment 320 extends along the second direction Y and is spaced apart along the first direction X. The photovoltaic cleaning robot 70 extends along the second direction Y. In other words, the length directions of the fixed segment 320 and the photovoltaic cleaning robot 70 are the same as the second direction Y. The sensing structure 410 is installed at the bottom of the fixed segment 320 and extends along the first direction X. At least a portion of the sensing structure 410 is located on the side of the fixed segment 320 away from the photovoltaic array 20, so as to correspond to the photovoltaic cleaning robot 70.

[0049] Example 2: The sensing structure 410 is installed on the first part 311 of the connecting section 310.

[0050] In this embodiment, the connecting segment 310 extends along the first direction X and is spaced apart along the second direction Y. The photovoltaic cleaning robot 70 extends along the second direction Y. In other words, the length direction of the connecting segment 310 is the same as the first direction X, and the length direction of the photovoltaic cleaning robot 70 is the same as the second direction Y. The sensing structure 410 is installed at the bottom of the connecting segment 310 and extends along the first direction X.

[0051] In some embodiments, such as Figure 1 As shown, Figure 1 This is one of the structural schematic diagrams of the photovoltaic system 1 provided in the embodiments of this application. The projection of the connecting bridge 30 along the vertical direction surrounds the projection of the column 120 of the photovoltaic support 10 along the vertical direction, and the vertical direction intersects with the first direction X.

[0052] In this embodiment, the vertical projection of the connecting cable tray 30 is rectangular, the vertical projection of the connecting cable tray 30 surrounds the vertical projection of the column 120 of the photovoltaic support 10, and the vertical projection of the connecting cable tray 30 and the vertical projection of the column 120 of the photovoltaic support 10 are spaced apart in the horizontal direction.

[0053] It is understandable that the vertical alignment of the connecting cable tray 30 with the column 120 of the photovoltaic support 10 helps to improve the load-bearing capacity of the connecting cable tray 30.

[0054] In some embodiments, such as Figure 5 and Figure 6 As shown, Figure 5 This is the fourth structural schematic diagram of the photovoltaic system 1 provided in the embodiments of this application. Figure 6 This is the fifth structural schematic diagram of the photovoltaic system 1 provided in the embodiments of this application. The photovoltaic system 1 also includes a first commutation position 50 and a second commutation position 60, which are respectively installed at both ends of the photovoltaic bracket 10 along the first direction X, and are both connected to the end of the photovoltaic array 20.

[0055] In this embodiment, the photovoltaic bracket 10 is provided with reversing positions at both ends along the first direction X. The reversing position is the position where the photovoltaic cleaning robot 70 changes its direction of movement after cleaning multiple photovoltaic modules on a photovoltaic bracket 10. After reaching the end of the photovoltaic bracket 10, the photovoltaic cleaning robot 70 performs a reversing operation through the reversing position. For example, the photovoltaic cleaning robot 70 can realize the reversing function by recognizing the baffle of the reversing position.

[0056] In addition, the top of the photovoltaic cleaning robot 70 is equipped with a photovoltaic panel for charging. The reversing position can also have the function of cleaning the photovoltaic panel of the photovoltaic cleaning robot 70. For example, the photovoltaic system 1 can include a first reversing position 50 and a second reversing position 60. Both the first reversing position 50 and the second reversing position 60 are used for reversing operations, and one of the first reversing position 50 and the second reversing position 60 has a cleaning function and can be used to clean the photovoltaic panel of the photovoltaic cleaning robot 70.

[0057] The first reversing position 50 is used to perform the reversing operation of the photovoltaic cleaning robot 70, and the second reversing position 60 is used to perform the reversing operation of the photovoltaic cleaning robot 70. When the photovoltaic cleaning robot 70 reverses at the second reversing position 60, the second reversing position 60 can clean the charging components of the photovoltaic cleaning robot 70.

[0058] In some embodiments, such as Figure 8 As shown, Figure 8 yes Figure 7 A partial enlarged view at point B. The first reversing position 50 includes a first reversing position bracket 510 and a first sensing baffle 520. The first reversing position bracket 510 includes a first segment 511, a second segment 512 and a third segment 513 connected in sequence. The second segment 512 is installed on the purlin 110 of the photovoltaic bracket 10. The first sensing baffle 520 is installed on the second segment 512. At least a portion of the projection of the first sensing baffle 520 along the first direction X coincides with the projection of the photovoltaic cleaning robot 70 along the first direction X.

[0059] In this embodiment, the first reversing position 50 is located at one end of the photovoltaic bracket 10. The first reversing position 50 may include a first reversing position bracket 510 and a first sensing baffle 520. The first reversing position bracket 510 is the main structure of the first reversing position 50. The first sensing baffle 520 is installed on the first reversing position bracket 510, and the first sensing baffle 520 includes, but is not limited to, a C-shaped structure facing the photovoltaic cleaning robot 70.

[0060] When the photovoltaic cleaning robot 70 detects that the distance to the first sensing baffle 520 is less than a certain value, the photovoltaic cleaning robot 70 reaches the first reversing position 50 and changes its direction of movement at the first reversing position 50.

[0061] The first commutation support 510 includes a first segment 511, a second segment 512, and a third segment 513 connected in sequence. The first segment 511 and the third segment 513 are L-shaped structures, the second segment 512 is a long strip structure, and the second segment 512 is installed on the purlin 110 of the photovoltaic support 10 by bolts or other connection structures. The first segment 511 and the third segment 513 are distributed at intervals along the second direction Y.

[0062] It should be noted that the first segment 511 and the third segment 513 of the first reversing bracket 510 both include limiting structures, and the limiting structures of the first segment 511 and the third segment 513 extend in opposite directions to each other, thereby blocking the photovoltaic cleaning robot 70.

[0063] In addition, the first commutation position 50 may also include a corner connector and a component connector 530. The corner connector is L-shaped, and the first segment 511 and the third segment 513 each include two mutually perpendicular sub-segments. The corner connector is installed at the sub-segment connection of the first segment 511 and the third segment 513, which helps to increase the strength of the first segment 511 and the third segment 513. The component connector 530 is T-shaped, and the first segment 511 and the third segment 513 are connected to the second segment 512 through the component connector 530. The first commutation position bracket 510 is connected to the photovoltaic row 20 through the component connector 530.

[0064] In some embodiments, such as Figure 9 As shown, Figure 9 yes Figure 7 A partial enlarged view at point C. The second reversing position 60 includes a second reversing position bracket 610, a second sensing baffle 620, and a cleaning component 630. The second reversing position bracket 610 is mounted on the purlin 110 of the photovoltaic bracket 10. The second sensing baffle 620 and the cleaning component 630 are both mounted on the second reversing position bracket 610. At least a portion of the projection of the second sensing baffle 620 along the first direction X coincides with the projection of the photovoltaic cleaning robot 70 along the first direction X. The cleaning component 630 is located above the second reversing position bracket 610.

[0065] In this embodiment, the second reversing position 60 is located at one end of the photovoltaic bracket 10. The second reversing position 60 may include a second reversing position bracket 610 and a second sensing baffle 620. The second reversing position bracket 610 is the main structure of the second reversing position 60. The second sensing baffle 620 is installed on the second reversing position bracket 610, and the second sensing baffle 620 includes, but is not limited to, a C-shaped structure facing the photovoltaic cleaning robot 70.

[0066] When the photovoltaic cleaning robot 70 detects that the distance to the second sensing baffle 620 is less than a certain value, the photovoltaic cleaning robot 70 reaches the second reversing position 60 and changes its direction of movement at the second reversing position 60.

[0067] The second commutation bracket 610 includes multiple segments to form a rectangular frame structure. The two sides of the rectangular frame structure spaced apart along the first direction X are installed on the purlins 110 of the photovoltaic bracket 10 by bolts or other connecting structures. The length of the side of the two sides spaced apart along the first direction X that is farther away from the photovoltaic row 20 along the second direction Y is greater than the length of the side of the side that is closer to the photovoltaic row 20 along the second direction Y.

[0068] It should be noted that the protruding structure on the side furthest from the photovoltaic array 20 of the two sides spaced apart along the first direction X is used to block the photovoltaic cleaning robot 70.

[0069] In addition, the second reversing position 60 may also include a cleaning component 630, which is mounted on the second reversing position bracket 610 and is used to clean the charging components of the photovoltaic cleaning robot 70 when the photovoltaic cleaning robot 70 reverses direction.

[0070] In some embodiments, the cleaning assembly 630 includes a brush fixing bracket 631 and a cleaning brush 632. The brush fixing bracket 631 is mounted on the second reversing position bracket 610, and the cleaning brush 632 is mounted on the brush fixing bracket 631. The cleaning brush 632 is used to clean the charging components of the photovoltaic cleaning robot 70 when the photovoltaic cleaning robot 70 reverses direction.

[0071] In this embodiment, the cleaning assembly 630 is installed on the second reversing bracket 610. The cleaning assembly 630 includes a brush fixing bracket 631 and a cleaning brush 632. The brush fixing bracket 631 is installed on the section of the second reversing bracket 610 that is spaced apart along the first direction X, away from the photovoltaic array 20. The brush fixing bracket 631 is located above the second reversing bracket 610. The brush fixing bracket 631 can be two L-shaped structures spaced apart along the second direction Y. One end of the L-shaped structure is connected to the second reversing bracket 610, and the other end of the L-shaped structure is connected to the cleaning brush 632. The cleaning brush 632 is located on the side of the brush fixing bracket 631 closer to the photovoltaic array 20.

[0072] When the photovoltaic cleaning robot 70 reaches the second reversing position 60 and changes its direction of movement at the second reversing position 60, the cleaning brush 632 can clean the charging components of the photovoltaic cleaning robot 70.

[0073] In some embodiments, such as Figure 10 As shown, Figure 10 This is a schematic diagram of the structure of the photovoltaic cleaning robot 70 of the photovoltaic system 1 provided in this application embodiment. The photovoltaic cleaning robot 70 may include an identification device 710 and a windproof component 720. The identification device 710 is used to identify the sensing structure 410, and the windproof component 720 is used to limit the engagement with the positioning hole 411 on the sensing structure 410.

[0074] In this embodiment, the photovoltaic cleaning robot 70 may include an identification device 710 and a windproof component 720. The identification device 710 includes a sensor switch 711 and an ultrasonic sensor 712. Taking the photovoltaic cleaning robot 70 located at the parking position 40 as an example, the ultrasonic sensor 712 is installed on the side of the sensor switch 711 away from the sensing structure 410. Both the sensor switch 711 and the ultrasonic sensor 712 can be used to identify the sensing structure 410. For example, the sensor switch 711 and the ultrasonic sensor 712 can determine the position of the parking position 40 by detecting the distance from the sensing structure 410. In addition, the windproof component 720 includes an anti-fall hook and a motor assembly. The motor assembly includes a motor, a mounting component, a limiting component, and a fixing component. The motor includes, but is not limited to, a push rod motor. The motor, the limiting component, the fixing component, the anti-fall hook, and the identification device 710 are all mounted on the mounting component. The fixing component is located on the side of the motor facing the sensing structure 410. A portion of the anti-fall hook is parallel to the sensing structure 410, and another portion is located at the bottom of the sensing structure 410. The limiting component is located on the side of the motor away from the sensing structure 410. The identification device 710 is located at the bottom of the motor, and at least a portion of the motor is limited and engaged with the positioning hole 411 on the sensing structure 410.

[0075] When the photovoltaic cleaning robot 70 is in the parking position 40, the photovoltaic cleaning robot 70 cooperates with the sensing structure 410 to limit the movement, which helps the photovoltaic cleaning robot 70 to cope with severe weather such as strong winds.

[0076] It should be noted that the redundant identification design of the inductive switch 711 and the ultrasonic sensor 712 can improve the reliability of the photovoltaic cleaning robot 70 stopping, and help reduce the risk of coupling deviation between the windproof component 720 and the sensing structure 410 caused by the photovoltaic cleaning robot 70 climbing upwards and inaccurate stopping.
