[0034] The embodiment of the present application provides a photovoltaic bracket for installing photovoltaic modules. In a photovoltaic power station system, the photovoltaic bracket is used to install photovoltaic modules, which can achieve regular monitoring and timely cleaning of the dirtiness of the photovoltaic modules, thereby avoiding hot spots caused by dirt, avoiding dirt blocking the photovoltaic modules from absorbing light, and improving the power generation efficiency and service life of the photovoltaic power station system.

[0035] Figure 1 A schematic structural diagram of a photovoltaic bracket according to an embodiment of the present application is shown. Figure 2 A schematic partial structural diagram of a photovoltaic bracket according to an embodiment of the present application is shown. Figure 3 Shows Figure 2 A local enlarged structural diagram of the A position in the figure. Figures 1 to 3 As shown, the photovoltaic support includes a supporting unit, a moving unit, a dirt detection unit and a cleaning unit.

[0036] The support unit includes two cross bars 110 and at least two strips 120 ; the two cross bars 110 are arranged opposite to each other; two ends of the strips 120 are respectively fixedly connected to the two cross bars 110 , and the photovoltaic module 500 is fixed on at least two strips 120 .

[0037] In one example, the number of the bars 120 can be two, and the two bars 120 are mounted on the two crossbars 110 to form a square frame. The photovoltaic module 500 is mounted on the frame, and the two ends of the photovoltaic module 500 are mounted on the bars 120. The photovoltaic module 500 can be fixedly connected to the bars 120; multiple photovoltaic modules 500 can be mounted in one frame along the extension direction of the bars 120 to install a row of photovoltaic modules 500.

[0038] In one example, the number of the bars 120 can be 4, and the four bars 120 are mounted on two cross bars 110. The two bars 120 form a frame for mounting the photovoltaic components 500 between the two cross bars 110, and two frames are formed between the four bars 120 and the two cross bars 110, so that two rows of photovoltaic components 500 can be mounted on the photovoltaic bracket.

[0039] It is understandable that the number of the beams 120 may also be 6, 8, or 9, etc. The number of the beams 120 is set according to the requirements of the photovoltaic system to be installed.

[0040] The moving unit includes a moving mechanism and a first slider 210, and the moving mechanism drives the first slider 210 to move between the two crossbars 110. The moving unit can be a driving force for cleaning at least one row of photovoltaic components 500, for example, driving the dirt detection unit to move so that the dirt detection unit can detect multiple positions of at least one row of photovoltaic components 500 to ensure that the detection results are accurate and comprehensive.

[0041] The dirt detection unit includes a support rod 320 and a data acquisition device 310 . The head end of the support rod 320 is fixedly connected to the first slider 210 , and the tail end of the support rod 320 is fixedly connected to the data acquisition device 310 .

[0042] The support rod 320 can be bent or folded so that the data collection device 310 can collect data from above the photovoltaic assembly 500 .

[0043] In the embodiment of the present application, the sliding of the first slider 210 drives the dirt detection unit to move, so that the dirt detection unit can detect multiple positions of at least one row of photovoltaic components 500, thereby ensuring that the detection results are accurate and comprehensive.

[0044] The cleaning unit includes a cleaning member and a first driving mechanism. The cleaning member is used to clean the photovoltaic assembly 500 . The first driving mechanism drives the cleaning member to move between the two cross bars 110 .

[0045] When the dirt detection unit detects that the photovoltaic assembly 500 is dirty, the cleaning unit moves to the dirty area and performs local cleaning on the dirty area, thereby avoiding excessive material and human resources in one cleaning.

[0046] In the embodiment of the present application, the dirty area is determined based on the detection result of the dirt detection unit. When the dirty area is determined, the cleaning room is controlled to move to the dirty area for cleaning. There is no need to clean the entire surface of the photovoltaic module 500 at one time, thereby improving the cleaning efficiency and being able to deal with dirt more promptly, thereby improving the power generation efficiency of the photovoltaic module 500.

[0047] In one embodiment, the moving mechanism includes a second driving mechanism and a sliding rod 220 , the two ends of the sliding rod 220 are respectively fixedly connected to the two cross bars 110 , and the first sliding block 210 is sleeved on the sliding rod 220 ; the second driving mechanism drives the first sliding block 210 to slide along the sliding rod 220 .

[0048] By sleeve-mounting the first slider 210 on the slide bar 220, the first slider 210 can be limited to move between the two cross bars 110 along the direction of the slide bar 220. The data acquisition device 310 driven by the first slider 210 also moves between the two cross bars 110, so that image data of multiple positions of the photovoltaic assembly 500 can be dynamically acquired.

[0049] In one example, when the first slider 210 moves, the movement coordinates of the first slider 210 can be collected, so as to determine the specific position coordinates of the dirty area, so that the cleaning unit moves to the dirty area for directional cleaning.

[0050] The second driving mechanism may be any driving device capable of driving the first slider 210 to move along the direction of the slide bar 220. For example, the slide bar 220 may be a screw rod, and screw transmission is performed between the first slider 210 and the slide bar 220. This driving method is relatively slow. The embodiment of the present application provides a moving method in which the first slider 210 is driven by a moving trolley 232, as described below.

[0051] In one embodiment, the second driving mechanism includes a limiting slide groove 231, a moving trolley 232 and a first connecting rod 233; the limiting slide groove 231 is arranged below the two cross bars 110 and located between the two cross bars 110; the moving trolley 232 moves in the limiting slide groove 231; the head end of the first connecting rod 233 is fixedly connected to the moving trolley 232, and the end of the first connecting rod 233 is fixedly connected to the first slider 210.

[0052] The limiting slide groove 231 may be a groove structure, and the depth of the groove is adapted to the height of the moving trolley 232 , so that the moving trolley 232 is limited to move within the limiting slide groove 231 .

[0053] The first connecting rod 233 connects the moving trolley 232 and the first sliding block 210 , so that the moving trolley 232 can drive the first sliding block 210 to move.

[0054] The width of the limiting slide groove 231 may be greater than the width of the moving trolley 232 , so that the moving trolley 232 can move along the length direction of the limiting slide groove 231 and also along the width direction of the limiting slide groove 231 .

[0055] In one example, the slide bar 220 may be a straight slide bar 220 or a curved slide bar 220, and may be curved in any shape; the width of the limiting slide groove 231 is adapted to the width of the slide bar 220. If the slide bar 220 is a straight slide bar, the width of the limiting slide groove 231 is sufficient to accommodate the moving trolley 232. If the slide bar 220 is a curved slide bar 220, the width of the limiting slide groove 231 is greater than the width of the slide bar 220, so that the moving trolley 232 can move laterally as the slide bar 220 bends.

[0056] The mobile vehicle 232 may have an electric drive device which is equipped with a power source and can be charged.

[0057] In the embodiment of the present application, the first slider 210 is driven to move by the moving trolley 232. Compared with the screw transmission, the movement of the moving trolley 232 is not limited by speed. When the target position is determined, it can be accelerated first, and then decelerated when approaching the target position, so that it can move to the target position accurately and improve the movement efficiency.

[0058] When the mobile cart 232 drives the data acquisition device 310 to collect data, uniform motion can be adopted. The movement of the mobile cart 232 does not contact or approach other hardware devices, so that the movement of the mobile cart 232 drives the first slider 210 to move, and vibration is not likely to occur, so that the image results collected by the data acquisition device 310 are more stable.

[0059] In one embodiment, the second driving mechanism further includes a busbar (not shown in the figure) and a busbar brush (not shown in the figure), the busbar is laid in the limiting slide groove 231, and the busbar brush is arranged on one side of the limiting slide groove 231 close to the cross bar 110.

[0060] A busbar and a busbar brush are arranged in the limiting slide groove 231 to charge the mobile trolley 232 , so as to prevent the data acquisition device 310 or the cleaning unit from being located above the photovoltaic module 500 when the mobile trolley 232 loses power, thereby affecting the power generation of the photovoltaic module 500 .

[0061] The sliding contact brush may be electrically connected to the electrical output terminal of the photovoltaic assembly 500 to draw electricity from the photovoltaic assembly 500 .

[0062] The sliding contact brush may also be electrically connected to the data acquisition device 310 to provide power to the data acquisition device 310 .

[0063] In one example, the photovoltaic bracket can also be provided with an inductive coupling system, which uses the principle of electromagnetic induction to provide wireless power supply to provide backup power for the mobile vehicle 232. The installation of the inductive coupling system is more flexible and is not limited by the length of the positioning slot 231.

[0064] In one embodiment, the support unit also includes at least two columns 130 for fixing the two cross bars 110; the at least two columns 130 include a first column 130 and a second column 130 respectively used to fix the two cross bars 110, and the first column 130 and the second column 130 are arranged opposite to each other; the limiting slide groove 231 is arranged between the first column 130 and the second column 130.

[0065] like Figure 1 As shown, the column 130 is used to be fixed to the installation area of ​​the photovoltaic system, and the installation area can be the ground or the roof.

[0066] In one example, if Figure 1As shown, four columns 130 are included, wherein one crossbar 110 is fixed to every two columns 130, and the tilt angle of the photovoltaic assembly 500 can be adjusted by adjusting the height difference between the two columns 130. The four columns 130 include a first column 130 and a second column 130 located on the same side of the crossbar 120, and a limiting slide groove 231 is provided between the first column 130 and the second column 130 to fix the limiting slide groove 231.

[0067] In one example, for Figure 1 As shown, the first column 130 and the second column 130 can also extend outward through the mounting plate, that is, the first column 130 and the second column 130 are respectively fixed with a mounting plate, and then the limiting slide groove 231 is fixedly connected to the two mounting plates, so that the limiting slide groove 231 can protrude from the sandalwood bar 120 or the photovoltaic component 500, and the installation position of the limiting slide groove 231 can be conveniently adjusted by adjusting the length of the mounting plate, so as to facilitate the movement of the mobile trolley 232 and drive the first slider 210 to move.

[0068] The limiting sliding groove 231 is disposed on one side of the photovoltaic support close to the sliding rod 220 .

[0069] In one embodiment, the first driving mechanism includes a second connecting rod 420 , a head end of the second connecting rod 420 is connected to the first sliding block 210 , and a tail end of the second connecting rod 420 is connected to the cleaning member.

[0070] In the embodiment of the present application, through the connection of the second connecting rod 420, when the first slider 210 moves, the cleaning element can be driven to move, so that the cleaning unit and the dirt detection unit share the same power drive device, reducing the hardware setting, making the structure of the photovoltaic bracket more simple, and avoiding too many devices causing the installation efficiency of the photovoltaic bracket.

[0071] The cleaning member moves with the first slider 210 to clean the photovoltaic module 500. The cleaning member and the data acquisition device 310 are fixed to the first slider 210, so that the data acquisition device 310 can preliminarily clean the photovoltaic module 500, for example, to clean the dust on the surface of the photovoltaic module 500.

[0072] The cleaning member and the data acquisition device 310 are both arranged above the photovoltaic component 500, that is, above the sandalwood bar 120; to prevent the cleaning member from blocking the collection operation of the data acquisition device 310, the cleaning member and the data acquisition device 310 can be distributed front and back along the sliding direction of the first slider 210.

[0073] In one example, the cleaning piece may be located at the front end of the data acquisition device 310, which is an end close to the photovoltaic component 500, so that the data acquisition device 310 collects data on the photovoltaic component 500 after preliminary cleaning, thereby preventing dust on the surface of the photovoltaic component 500 from affecting data collection.

[0074] In one example, the data acquisition device 310 may be located at the front end of the cleaning member, which can reduce the sliding distance of the first slider 210. For example, when the data acquisition device 310 collects data from the outermost photovoltaic component 500, data can be obtained before reaching the outermost position. If the cleaning member is in front, in order to collect data from the outermost photovoltaic component 500, the first slider 210 needs to continue to move forward to complete the data collection of the outer photovoltaic component 500.

[0075] In one embodiment, the cleaning member includes a roller brush 410; the first driving mechanism also includes a guide groove 430 and a supporting wheel 440, the two ends of the guide groove 430 are respectively fixedly connected to the two cross bars 110, and the guide groove 430 and the first slider 210 are respectively arranged on the opposite sides of at least two cross bars 120; the supporting wheel 440 is fixedly connected to the rolling shaft 411 of the roller brush 410, and the supporting wheel 440 cooperates with the guide groove 430 so that the supporting wheel 440 rolls in the guide groove 430.

[0076] The embodiment of the present application cleans the photovoltaic module 500 by means of a roller brush 410. The roller brush 410 is arranged across at least two slats 120. When the roller brush 410 moves on the photovoltaic module 500, it contacts the upper surface of the photovoltaic module 500, thereby cleaning away dirt on the upper surface of the photovoltaic module 500. In actual application, the height of the roller brush 410 is matched with the height of the slats 120, so that the roller brush 410 can move on the surface of the photovoltaic module 500 and can brush away dirt.

[0077] The supporting wheel 440 is disposed at an end of the roller brush 410 opposite to the second connecting rod 420. The second connecting rod 420 is not connected to the rotating shaft, but may be connected to the outer shell component of the roller brush 410. The supporting wheel 440 may be fixedly connected to the rolling shaft 411, and the supporting wheel 440 rolls along with the rolling shaft 411.

[0078] The supporting wheel 440 is clamped in the guide groove 430, and the width of the guide groove 430 can be adapted to the axial size of the supporting wheel 440. The height of the guide groove 430 is adapted to the radius of the supporting wheel 440, so that the rolling shaft 411 is mounted on the guide groove 430. The height of the guide groove 430 is adapted to the radius of the supporting wheel 440, and the height of the guide groove 430 can be less than the radius of the supporting wheel 440, or equal to the radius of the supporting wheel 440 minus the radius of the rolling shaft 411, so that when the rolling shaft 411 is mounted on the guide groove 430, the supporting wheel 440 can contact the bottom of the guide groove 430. The supporting wheel 440 can contact the bottom of the guide groove 430, so that when the second connecting rod 420 drives the roller brush 410 to move, the supporting wheel 440 can roll, thereby driving the roller brush 410 to roll. In order to make the rolling brush 410 have greater friction, a rack can be set in the guide groove 430, and the supporting wheel 440 is a gear structure. The gear is driven to rotate by the rack, so that the rolling brush 410 has greater friction and the cleaning force of the photovoltaic component 500 is enhanced.

[0079] In one embodiment, the two cross bars 110 are respectively a first cross bar 110 and a second cross bar 110 ; the photovoltaic assembly 500 is fixed to an area close to the first cross bar 110 on at least two slats 120 , and a hollow area is formed near the second cross bar 110 .

[0080] In the photovoltaic support provided in the embodiment of the present application, a dirt detection unit and a cleaning unit are additionally provided, which can move on the photovoltaic assembly 500. However, if the dirt detection unit and the cleaning unit stay on the photovoltaic assembly 500 without detection and cleaning, the power generation efficiency of the photovoltaic assembly 500 will be greatly affected.

[0081] In the embodiment of the present application, a hollow area is formed near the second cross bar 110, that is, the photovoltaic component 500 is not installed in the area, which can facilitate the installation and control of the dirt detection unit and the cleaning unit and avoid affecting the power generation of the photovoltaic component 500.

[0082] In one embodiment, the cleaning unit further includes a serrated brush strip 450 , which is disposed at a first position of the hollow area, and a height of the serrated brush strip 450 matches a height of the roller brush 410 .

[0083] Since the photovoltaic support is provided with a hollow area, the sawtooth brush strip 450 can be higher than the height of the sandalwood strip 120, and can be flush with or slightly higher than the height of the photovoltaic module 500. When the roller brush 410 rolls over the sawtooth brush strip 450, the sawtooth brush strip 450 can brush off dust or larger stains on the roller brush 410, ensuring the cleanliness of the roller brush 410, and preventing the roller brush 410 with stains from rolling on the surface of the photovoltaic module 500, causing scratches on the packaging glass, and reducing the power generation efficiency of the photovoltaic module 500.

[0084] The sawtooth brush strips 450 can be provided in multiple strips according to the width of the roller brush 410 to ensure that the outer surface of the roller brush 410 is cleaned. The sawtooth brush strips 450 can be fixed on two opposite strips 120.

[0085] In one embodiment, the cleaning unit further includes a water spraying mechanism, which includes a water tank 460 and a plurality of nozzles 461 , wherein the plurality of nozzles 461 are disposed on the upper surface of the water tank 460 , and the water tank 460 is disposed at the second position of the hollow area.

[0086] The water tank 460 is filled with water, and the water is sprayed out through the spray head 461 and toward the roller brush 410, so that the roller brush 410 can be cleaned by spraying water.

[0087] In one example, after the roller brush 410 starts cleaning, the water spraying mechanism first sprays water toward the photovoltaic component 500, and then moves the roller brush 410 toward the photovoltaic component 500, so that the surface of the photovoltaic component 500 is cleaned with the roller brush 410 with water, which can clean various types of stains and cool the dirty areas at the same time, thereby reducing the high temperature caused by the hot spot effect caused by the dirt.

[0088] In one implementation, the data acquisition device 310 is a thermal imaging camera device or an image camera device.

[0089] The thermal imaging camera device collects the temperature distribution map of the surface of the photovoltaic module 500. If there is dirt on the surface of the photovoltaic module 500, a hot spot effect will occur, causing the temperature around the dirt to rise. Therefore, the dirty area can be determined based on the temperature distribution map.

[0090] The image camera device is used to capture the surface image of the photovoltaic module 500. The surface of the photovoltaic module 500 itself has the same appearance. The location where the appearance difference occurs is the location where the dirt appears. The judgment of the appearance difference can be determined by image processing.

[0091] The present application also provides a method for cleaning a photovoltaic module. Figure 4 As shown, including: S410, acquiring image data collected by a data collection device, and determining a dirt detection result based on the image data.

[0092] As in the above embodiment, the image data collected by the data collection device may be a temperature distribution image or a surface image. In the case where the image data is a temperature distribution image, the position where the temperature is higher than a preset threshold value may be determined as a dirty area. In the case where the image data is a surface image, the position where the appearance difference occurs is a dirty area.

[0093] The dirt detection result includes the center coordinates of the dirty area and the dirt size; the cleaning instruction includes the cleaning distance and the number of cleaning times. The cleaning distance is the reciprocating distance of the cleaning unit starting from the center coordinate for reciprocating cleaning; the cleaning number is the number of times the cleaning unit is controlled to perform reciprocating cleaning.

[0094] Based on the determined dirty area and the movement data of the mobile vehicle, the center coordinates of the dirty area can be determined, and based on the center coordinates and the dirty area, the edge coordinates of the dirty area or the size of the dirty area can be determined. Based on the dirty size, data processing can be performed to obtain the cleaning distance required for cleaning.

[0095] In one example, if the cleaning distance is 8 cm, the mobile trolley can drive the roller brush to move to the left of the center, and then the area 8 cm forward and 8 cm backward is the reciprocating cleaning area. That is, the reciprocating cleaning area is 16 cm.

[0096] In one example, the cleaning distance may be 8 cm forward and 6 cm backward, and the mobile trolley may drive the roller brush to move to the left of the center, and the area 8 cm forward and 6 cm backward is the area for reciprocating cleaning. That is, the reciprocating cleaning area is 14 cm.

[0097] In one example, the cleaning distance may be equal to the dirt size, and the dirt size may be greater than the dirt size to ensure that the dirty area is cleaned. The size greater than the dirt size may be preset, for example, 1 cm greater than the dirt size, that is, in the above example where the cleaning distance may be 8 cm forward and 6 cm backward, the actual detected dirt size is 7 cm forward of the center coordinate and 5 cm backward of the center coordinate.

[0098] The center coordinate may be the position where the temperature of the dirty area is the highest in the temperature distribution image; or may be the position where the appearance difference is the greatest in the surface image.

[0099] In an example, the center coordinates may also be the coordinates of any specified point in the detected dirty area.

[0100] The number of reciprocating cleanings is adapted to the degree of dirtiness of the dirty area. It is understandable that the dirtier the area, the more reciprocating cleanings are performed. The number of reciprocating cleanings may include a plurality of preset number values, and when determining the number of reciprocating cleanings, it is determined to be one of the plurality of preset number values. For example, the degree of dirtiness is divided into three levels, and each level has a corresponding number value. For example, when the degree of dirtiness is level three, the number of reciprocating cleanings is 7 times; when the degree of dirtiness is level two, the number of reciprocating cleanings is 5 times; when the degree of dirtiness is level one, the number of reciprocating cleanings is 2 times.

[0101] The degree of dirtiness of the dirty area can be determined based on the temperature value in the image data, and the higher the temperature, the higher the degree of dirtiness.

[0102] The degree of dirtiness of the dirty area can also be determined based on the dirt thickness in the image data; the higher the thickness, the higher the degree of dirtiness.

[0103] S420, generating a cleaning instruction based on the dirt detection result.

[0104] According to the center coordinates of the dirty area, the target position that the mobile cart needs to move to is generated; according to the size of the dirt, the moving distance or moving range of the mobile cart for reciprocating movement is generated.

[0105] S430, in response to the cleaning instruction, sending a corresponding control signal to the cleaning unit, so that the cleaning unit performs a cleaning operation in the target area indicated by the cleaning instruction.

[0106] The target area is an area indicated by coordinates determined based on the dirty area.

[0107] The control signal controls the movement of the mobile carriage. During the movement of the mobile carriage, the roller brush moves on the upper surface of the photovoltaic module, thereby rolling and cleaning the photovoltaic module.

[0108] In one example, the roller brush may further include a starter device, and when the starter device is turned on, the roller brush rolls to clean the photovoltaic assembly. The cleaning instruction may also include an on and off operation of the starter device.

[0109] In the embodiment of the present application, based on the detection result of the dirt detection unit, when the dirty area is determined, the cleaning room is controlled to move to the dirty area for cleaning. There is no need to clean the entire surface of the photovoltaic module at one time, thereby improving the cleaning efficiency and being able to deal with dirt more promptly, thereby improving the power generation efficiency of the photovoltaic module.

[0110] In one embodiment, the data acquisition device acquires image data of the photovoltaic assembly according to a preset time period.

[0111] The time period may be one week, one day, etc. By periodically collecting image data instead of periodically cleaning, damage to the photovoltaic modules can be reduced, and it is avoided that when there is no stain on the photovoltaic modules, the photovoltaic modules are cleaned aimlessly, which affects the quality of the photovoltaic modules.

[0112] In the embodiment of the present application, image data of the photovoltaic module is collected at preset time period intervals. When there is no dirt, cleaning is not started; when there is dirt, the cleaning unit reciprocates in the dirty area to ensure that the dirty area is cleaned thoroughly without the need to clean the entire photovoltaic module, thereby improving the cleaning efficiency.

[0113] The photovoltaic module cleaning method provided in the embodiment of the present application may also include sending a roller brush cleaning instruction, which includes controlling the roller brush to move to a first position and / or a second position of the perforated area to achieve water spray cleaning or brush strip cleaning of the roller brush.

[0115] In one embodiment, the dirt detection result in the dirt detection module 501 includes the center coordinates and dirt size of the dirty area; the cleaning instruction includes the cleaning distance and the number of cleaning times, the cleaning distance is the reciprocating distance of controlling the cleaning unit to perform reciprocating cleaning starting from the center coordinate; the number of cleaning times is the number of times the cleaning unit is controlled to perform reciprocating cleaning.

[0116] In one embodiment, the data acquisition device in the dirt detection module 501 acquires image data of the photovoltaic module according to a preset time period.
