[0030] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0031] like Figures 1-12As shown, a bidirectional photovoltaic power generation flexible adjustment bracket for tracking light includes a stand 1; the number of the stand 1 is two, and the two stands 1 are located on both sides of the whole body for providing elevated support, and an inclined beam 101 is fixedly installed on the side of the stand 1; it is characterized by further comprising: A support rope 4, both ends of which are connected to a first adjustment mechanism 2 via a tensioning mechanism 6, and the first adjustment mechanism 2 is mounted on the top of the stand 1; A second adjustment mechanism 8, wherein the number of the second adjustment mechanism 8 is multiple, and the multiple second adjustment mechanisms 8 are installed at equal intervals along the length direction of the support rope 4; the second adjustment mechanism 8 is connected to the photovoltaic panel 3; A movable rope 7, wherein the movable rope 7 is connected to the input portion of the plurality of second adjustment mechanisms 8, and each end of the movable rope 7 is connected to a pulling mechanism 5; The cleaning scraper bar 14 is connected to a moving mechanism 15 .

[0032] like Figure 1-Figure 2 As shown, as a specific technical solution, the first adjusting mechanism 2 includes a first motor 202; the first motor 202 is fixedly installed to the top of the stand 1, the output shaft end of the first motor 202 is fixedly connected to the first rotating shaft 203, and the first rotating shaft 203 is rotatably installed to the top of the stand 1, and the first rotating shaft 203 is fixedly connected to the frame plate 201.

[0033] The two first adjustment mechanisms 2 are respectively installed on the two vertical frames 1. The two first adjustment mechanisms 2 are used to flip and adjust the support rope 4, thereby realizing the adjustment of the photovoltaic panel 3 on the support rope 4; the specific adjustment process is as follows: the first motor 202 drives the first rotating shaft 203 and the frame plate 201 to rotate, thereby driving the support rope 4 connected to the frame plate 201 to rotate.

[0034] like Figure 2 As shown, as a specific technical solution, the tensioning mechanism 6 includes a movable frame 604 and a connecting rod 606; a stud 602 is rotatably installed in the middle of the movable frame 604, and the stud 602 is threadedly connected to a fixing nut 601 fixedly installed on the frame plate 201, and a turntable 603 is fixedly installed on the end of the stud 602 away from the movable frame 604, and a guide column 605 is fixedly installed on the movable frame 604, and the guide column 605 is connected to the guide hole on the frame plate 201, and a ring is provided at one end of the connecting rod 606, and the ring is sleeved on the end of the movable frame 604, and a nut 607 is threadedly connected on the end of the movable frame 604, and the connecting rod 606 passes through the hole on the frame plate 201, and the connecting rod 606 is fixedly connected to the support rope 4.

[0035] The tensioning mechanism 6 is used to tension the support rope 4 on the frame plate 201 of the two first adjustment mechanisms 2; specifically, after the support rope 4 is fixed to the connecting rod 606, the support rope 4 is not tightened. By turning the turntable 603, the stud 602 and the fixing nut 601 are threaded, and the guide column 605 and the guide hole are guided to drive the movable frame 604 to move, and the movable frame 604 pulls the connecting rod 606 to tighten the support rope 4.

[0036] like Figure 6 As shown, as a specific technical solution, the second adjustment mechanism 8 includes a shell 801 fixedly mounted on the support rope 4; a second rotating shaft 804 is rotatably mounted in the shell 801, and a gear 805 is fixedly sleeved on the second rotating shaft 804, and the gear 805 is meshedly connected with a rack 802, and the rack 802 is fixedly mounted on the movable rope 7, and both sides of the shell 801 are provided with hole sleeves 8011 for the movable rope 7 to pass through; a guide rail 803 is fixedly mounted in the shell 801, and the rack 802 is slidably mounted on the guide rail 803.

[0037] The two hole sleeves 8011 are respectively used for the movable rope 7 to enter and exit the shell 801; when the movable rope 7 is dragged by the dragging mechanism, the movable rope 7 drives the rack 802 of the second adjustment mechanism 8 to move together, and through the engagement transmission between the rack 802 and the gear 805, the second rotating shaft 804 is driven to rotate, and the second rotating shaft 804 drives the photovoltaic panel 3 to flip and adjust.

[0038] The first adjustment mechanism 2 and the second adjustment mechanism 8 are used to drive the photovoltaic panel 3 to adjust in two directions; specifically, the first adjustment mechanism 2 performs angle adjustment in the north-south direction, and the second adjustment mechanism 8 performs angle adjustment in the east-west direction, thereby realizing bidirectional light chasing.

[0039] Compared to existing technologies, the second adjustment mechanism 8 moves by pulling the movable rope 7 through the pulling mechanism 5, thereby driving the racks 802 in all second adjustment mechanisms 8 to move synchronously, achieving joint drive. This design cleverly avoids the need for a separate power source for each second adjustment mechanism 8 and the power connection and control required for each power source, simplifying the structure. The first adjustment mechanism 2 is installed on both sides of the overall structure. Through the coordinated operation of both sides, the synchronous angle adjustment of all photovoltaic panels 3 can be achieved, eliminating the need for separate angle adjustment devices for each photovoltaic panel 3 in the north-south direction.

[0040] like Figure 2-Figure 4As shown, as a specific technical solution, the pulling mechanism 5 includes a screw 502 and a wheel body 507; both ends of the screw 502 are rotatably connected to an end seat 501, the end seat 501 is fixedly mounted on the frame plate 201, a second motor 503 is fixedly mounted on the end seat 501, the output shaft end of the second motor 503 is fixedly connected to the end of the screw 502, a guide rod 505 is fixedly mounted between the two end seats 501, a movable seat 504 is threadedly connected to the screw 502, a guide groove is provided on the movable seat 504, the guide groove is slidably engaged with the guide rod 505, a mounting frame 508 is fixedly mounted on the frame plate 201, the wheel body 507 is rotatably mounted on the mounting frame 508, the movable rope 7 passes through the through hole provided on the frame plate 201, the movable rope 7 passes around the wheel body 507, and the end of the movable rope 7 is fixedly connected to the movable seat 504. The pulling mechanism 5 further includes a protective cover 506 , which is mounted on the frame plate 201 . The protective cover 506 surrounds all components of the pulling mechanism 5 except the protective cover 506 itself to provide protection.

[0041] When the movable rope 7 moves, one pulling mechanism 5 pulls the movable rope 7 so that the movable rope 7 is retracted into its protective cover 506, while the other pulling mechanism 5 releases the movable rope 7 from its protective cover 506. The two pulling mechanisms 5 alternately perform the above-mentioned driving to realize the left and right movement of the movable rope 7.

[0042] The specific operation of the pulling mechanism 5 is as follows: the second motor 503 drives the screw 502 to rotate, the screw 502 and the movable seat 504 are threaded, and the guide rod 505 slides with the guide groove on the movable seat 504 to provide guidance, so that the movable seat 504 moves, and the movable seat 504 drives the end of the movable rope 7 to move together, thereby realizing the driving of the movable rope 7.

[0043] like Figure 1 Figure 5 as well as Figure 7 As shown, as a specific technical solution, a first protective box 10 and a second protective box 11 are provided on the front side of each of the multiple second adjustment mechanisms 8; the front and rear sides of the photovoltaic panel 3 are fixedly connected to the second protective box 11 and the first protective box 10 respectively; a moving mechanism 15 is provided in each of the first protective box 10 and the second protective box 11; the first protective box 10 is fixedly connected to the second rotating shaft 804 of the second adjustment mechanism 8.

[0044] The first protection box 10 and the second protection box 11 provide a space for installing the moving mechanism 15 . The moving mechanism 15 is used to drive the cleaning strip 14 to scrape the top surface of the photovoltaic panel 3 to remove dirt attached to the surface.

[0045] like Figure 7 and Figure 9As shown, as a specific technical solution, the moving mechanism 15 includes two first pulleys 1501 and a first transmission belt 1502; the first transmission belt 1502 is wound around the two first pulleys 1501, and the first pulley 1501 is rotatably installed inside the first protective box 10 and the second protective box 11. A connecting shaft 13 is rotatably installed between the first protective box 10 and the second protective box 11, and the two ends of the connecting shaft 13 are respectively fixedly connected to the first pulley 1501 located in the first protective box 10 and the first pulley 1501 located in the second protective box 11; the first transmission belt 1502 is connected to a slider 16, and the first protective box 10 and the second protective box 11 are both provided with a slide groove 12, and the slider 16 is slidably connected to the slide groove 12, and the slider 16 is connected to the end of the cleaning scraper 14.

[0046] like Figure 9 As shown, as a specific technical solution, a transmission mechanism 20 is provided in the second protective box 11; the transmission mechanism 20 includes a second pulley 2002 and a third pulley 2003, the diameter of the third pulley 2003 is larger than the diameter of the second pulley 2002, and the second pulley 2002 and the third pulley 2003 are wrapped with a second transmission belt 2001, and the second pulley 2002 is coaxially fixedly connected to a first pulley 1501 in the second protective box 11.

[0047] When driving the third pulley 2003 to rotate about the second protective box 11, the belt transmission provided by the second transmission belt 2001 causes the second pulley 2002 to rotate, and the second pulley 2002 drives the first pulley 1501 to rotate, driving the first transmission belt 1502 to move, and the first transmission belt 1502 drives the cleaning strip 14 through the slider 16 to scrape the photovoltaic panel 3 to achieve cleaning.

[0048] like Figure 5 and Figure 11 As shown, as a specific technical solution, the number of the support ropes 4 is two; the second adjusting mechanism 8 is installed on one of the support ropes 4, and a plurality of front seats 9 are fixedly installed on the other support rope 4 at equal intervals, and the front seat 9 is rotatably installed with a rotating cylinder 17, and the rotating cylinder 17 is fixedly connected to the second protection box 11; the third pulley 2003 is fixedly connected to a circular shaft 18 extending into the rotating cylinder 17, and the circular shaft 18 is rotatably connected to the second protection box 11, the circular shaft 18 is coaxially arranged with the rotating cylinder 17, and a 180° arc groove 1801 is opened on the end face of the circular shaft 18, the front seat 9 is fixedly connected with a fixing column 19, and the fixing column 19 is inserted into the arc groove 1801; a clockwork spring is installed between the circular shaft 18 and the second protection box 11.

[0049] When the photovoltaic panel 3 is in a horizontal state, Figure 8As shown, the fixed column 19 is located in the middle of the arc groove 1801. After driving the photovoltaic panel 3 to rotate 90° clockwise, the fixed column 19 moves relatively to one end of the arc groove 1801 and continues to drive the photovoltaic panel 3 to rotate clockwise. Through the obstruction of the fixed column 19, the circular shaft 18 cannot rotate with the photovoltaic panel 3, and the first protective box 10, the second protective box 11 and the internal structure thereof rotate together with the photovoltaic panel 3, so that the circular shaft 18 rotates relative to the above structure and twists the clockwork spring. Through the transmission of the third pulley 2003, the second pulley 2002 and the second transmission belt 2001, the first pulley 1501 rotates, driving the first transmission belt 1502 to move, and the first transmission belt 1502 drives the cleaning scraper 14 to move through the slider 16 to clean the photovoltaic panel 3.

[0050] After the photovoltaic panel 3 is cleaned, the photovoltaic panel 3 is driven to return to a horizontal state. The elastic force of the spring causes the shaft 18 and the second protective box 11 to rotate and return to their original position. The transmission mechanism 20 and the moving mechanism 15 drive the cleaning strip 14 to its original position. Figure 5 Position shown.

[0051] Through the above design, the cleaning strip 14 is indirectly driven by the movement of the movable rope 7 , and the cleaning operation of the cleaning strip 14 does not require an additional power source.

[0052] like Figure 6 As shown, this is a schematic diagram of the structural state of the second adjustment mechanism 8 when the photovoltaic panel 3 is in a horizontal state; the right side of the rack 802 has sufficient length. When the rack 802 moves to the left, the driving gear 805 and the second rotating shaft 804 rotate 90° clockwise together, and can continue to drive the gear 805 and the second rotating shaft 804 to rotate clockwise, while the left side of the rack 802 is shorter. When the rack 802 moves to the right, it is only enough to drive the gear 805 and the second rotating shaft 804 to rotate counterclockwise 90°.

[0053] The design of rotating clockwise and counterclockwise to 90° satisfies the light tracking adjustment, and the part rotating clockwise over 90° is used to drive the cleaning scraper 14.

[0054] The first pulley 1501 , the second pulley 2002 and the third pulley 2003 are synchronous pulleys, and the first transmission belt 1502 and the second transmission belt 2001 are synchronous belts.

[0055] like Figure 10As shown, as a specific technical solution, the slider 16 includes a frame 1601 fixed to the first transmission belt 1502; a connecting strip 1602 is slidably installed in the frame 1601, and the connecting strip 1602 is elastically connected to the inner wall of the frame 1601 through a spring 1603, and one end of the connecting strip 1602 is fixedly connected to the cleaning scraper 14.

[0056] like Figure 12 As shown in the figure, as a specific technical solution, the inner wall of the first protective box 10 and the inner wall of the second protective box 11 are both provided with a long groove 21, in which a stop bar 22 is fixedly installed. The long groove 21 is divided into a long and flat circular slide by the stop bar 22. A magnet 23 for magnetically attracting the connecting bar 1602 is fixedly installed at the bottom of one side of the circular slide, and the magnet 23 extends to the bottom of one end of the stop bar 22. The connecting bar 1602 is made of metal iron and can be magnetically attracted.

[0057] When the photovoltaic panel 3 is in a horizontal state, Figure 10 As shown, the spring 1603 is in a stretched state, and the position of the connecting strip 1602 in the circular slide is as shown in FIG. Figure 12 As shown, at this time, the connecting strip 1602 is magnetically attracted by the magnetic block 23, maintaining the stretched state of the spring 1603, and the cleaning strip 14 is in contact with the surface of the photovoltaic panel 3; when cleaning the photovoltaic panel 3, the slider 16 slides in the slide groove 12, and the connecting strip 1602 moves to the bottom of the stop bar 22 and is blocked by the stop bar 22. The connecting strip 1602 is not affected by the elastic force of the spring 1603 and moves upward. After the cleaning is completed, the connecting strip 1602 moves to the end of the return slide away from the magnetic block 23, loses the block bar 22 and is blocked by the spring 1603. The elastic force causes the connecting bar 1602 to move to the side above the stop bar 22, and the connecting bar 1602 drives the cleaning strip 14 to separate from the photovoltaic panel 3. When the photovoltaic panel 3 is reset to a horizontal state, the cleaning strip 14 is reset and moved. In this process, the cleaning strip 14 does not rub against the surface of the photovoltaic panel 3, reducing unnecessary wear. At the same time, the connecting bar 1602 moves above the stop bar 22. After the reset is completed, the connecting bar 1602 moves above the magnetic block 23. The magnetic attraction of the magnetic block 23 restores the connecting bar 1602 to the horizontal state. Figure 12 position and stretch spring 1603.

[0058] Through the above design, when the cleaning scraper 14 is cleaning, the cleaning scraper 14 can be in contact with the photovoltaic panel 3 to ensure the effect of scraping away dirt; and after cleaning, when the cleaning scraper 14 is reset, the cleaning scraper 14 is separated from the photovoltaic panel 3 to avoid unnecessary friction and wear of the cleaning scraper 14 and ensure its service life.

The scope of protection of the present invention is defined by the appended claims.
