Abstract
Description
Technical Field
[0001] This invention relates to the field of single-axis tracking photovoltaic support technology, specifically to a single-axis tracking photovoltaic power generation support and installation method. Background Technology
[0002] Single-axis tracking photovoltaic (PV) brackets can improve power generation efficiency by 15%-30% by adjusting the angle of the PV panels in real time to track the sun's trajectory, and have become the mainstream technology for large-scale PV power plants. A search revealed an existing patent (publication number: CN206629016U) that discloses a single-axis tracking PV power generation bracket, including a torque tube with a cap on top and a drive mechanism. The cap has a bearing at its top, and the torque tube is fixed within the bearing. The torque tube is horizontally mounted on top of the pile, and the PV panels are installed on the torque tube. The drive mechanism includes a thrust arm, a thrust rod, and a drive mechanism that drives the torque tube to rotate around its own axis. To allow for height adjustment and improved adaptability, the detachable cap and pile are adjusted via bolts at the mounting holes, allowing for vertical and horizontal position adjustments. To avoid on-site welding and speed up installation, the torque tube thrust rod is segmented, with adjacent segments of the torque tube and thrust rod detachably fixed together.
[0003] The existing technology still has the following significant drawbacks:
[0004] 1. The challenge of self-cleaning photovoltaic panels: Photovoltaic panels are commonly installed in arid and windy areas and rely heavily on external energy sources for cleaning. This requires additional power lines and control systems that cannot be linked to the rotation trajectory of the photovoltaic panels, increasing construction costs. They often require frequent manual cleaning, increasing the workload.
[0005] 2. Insufficient terrain adaptability of the support frame: The rigid structure is difficult to level. Traditional support frames use fixed-height columns, which require a lot of earthwork to level in undulating terrain. Once the installation position is offset, it is difficult to self-correct through structural adjustment. Summary of the Invention
[0006] This invention proposes a flat single-axis tracking photovoltaic power generation bracket and installation method, which solves the problems in related technologies that photovoltaic panels cannot self-clean during the flipping process and that the support frame has insufficient terrain adaptability.
[0007] The technical solution of the present invention is as follows: A single-axis tracking photovoltaic power generation bracket includes: a steering rod, a mounting frame and a synchronous shaft that are detachably fixed to the outside of the steering rod, an outer frame mounted on the mounting frame, and a photovoltaic panel mounted on the inner side of the outer frame. A base frame is provided on the lower side of the photovoltaic panel. Two arc-shaped abutment rods are symmetrically fixed to the top of one side of the base frame. Several multi-functional support frames are provided on the outside of the base frame to support the steering rod. The steering rod can be rotated in the multi-functional support frames by pushing the synchronous shaft.
[0008] The outer frame is provided with a cleaning mechanism, which includes two reciprocating sliders and a rubber scraper connected between the two reciprocating sliders. During the process of the photovoltaic panel flipping with the steering rod, the cleaning mechanism, in cooperation with the arc-shaped abutment rod, can clean the photovoltaic panel once by means of the rubber scraper.
[0009] A reset mechanism is provided between the steering rod and the outer frame to reset the reciprocating slider and rubber scraper after cleaning, thereby achieving secondary cleaning.
[0010] Preferably, two right-angled sliding grooves are provided on both sides of the outer wall of the outer frame, and the reciprocating slider is slidably connected to the right-angled sliding grooves.
[0011] Preferably, a fixing plate extends outward from the two corners of the outer frame and is fixedly connected thereto. A rotating roller is rotatably connected to the fixing plate. An elastic traction rope slides through the inner side of the rotating roller. One end of the elastic traction rope is fixedly connected to the reciprocating slider, and the other end of the elastic traction rope is connected to the outer wall of the base frame.
[0012] Preferably, a limiting component is provided on one side of the reciprocating slider. The limiting component includes a first insert plate and a second insert plate. The top of the first insert plate is rounded. A sliding cavity is provided on the inner side of the outer frame for the first insert plate and the second insert plate to slide. A return spring is connected between the first insert plate and the bottom of the sliding cavity, and between the second insert plate and the top of the sliding cavity. The first insert plate extends out of the upper outer wall of the outer frame, and the second insert plate extends out of the lower outer wall of the outer frame.
[0013] Preferably, the limiting component further includes a linkage gear rotatably connected inside the outer frame, and the outer walls of the first insert plate and the second insert plate on opposite sides are provided with tooth grooves that mesh with the linkage gear.
[0014] Preferably, the reset mechanism includes a second gear fixedly sleeved on the outer wall of the steering rod, a first gear meshing with one side of the second gear, a diagonal brace fixedly connected to the top of the base frame, and the first gear rotatably connected to the diagonal brace.
[0015] Preferably, the reset mechanism further includes a rectangular push frame, a T-shaped slider is fixedly connected to one side of the rectangular push frame, and a T-shaped slide rail that cooperates with the T-shaped slider is provided on the side wall of the outer frame, so that the rectangular push frame can slide along the side wall of the outer frame;
[0016] A telescopic rod is fixedly connected to the outer wall of the first gear. One end of the telescopic rod is hinged to a connecting rod, and the other end of the connecting rod is fixedly connected to the rectangular push frame.
[0017] Preferably, the multifunctional support frame includes a support column and a tray fixed to the top of the support column. A base is slidably clamped inside the tray, and a base is fixed to one side of the base. The base and the base are integrated into one piece. The base and the tray are slidably connected. A horizontally arranged lead screw is rotatably arranged inside the tray. The lead screw is threaded to the base and the base. By rotating the lead screw, the base and the base can be slidably displaced inside the tray.
[0018] A worm gear is rotatably connected to the top of the base, and a worm is meshed with one side of the worm gear. The worm is rotatably connected to the inside of the chassis. A support is fixed to the top of the worm gear, and a rotating component is installed on the upper side of the support.
[0019] Preferably, the rotating assembly includes two fixed outer rings, one end of which is rotatably connected by a rotating shaft, and the other end of which is detachably fixed by bolts. A rotating half-ring is rotatably sleeved on the inner side of each of the two fixed outer rings, and the steering rod is constrained by the two rotating half-rings.
[0020] A method for installing a single-axis tracking photovoltaic power generation bracket includes the following steps:
[0021] Step 1: Install the multi-functional support frame in rows along a straight line at equal intervals in the work area. Then, distribute the multi-functional support frame into multiple rows according to work needs in the same way, so that the multi-functional support frame is arranged in a matrix in the work area.
[0022] Step 2: Open the two fixed outer rings by rotating the shaft, place the steering rod inside the rotating half ring, and the longer steering rod will span several multi-functional support frames at the same time. Adjacent steering rods can be connected by bolts, and the base frame is fixed to the installation site.
[0023] Step 3: During the process of the multi-functional support frame being distributed in a matrix or during the installation of the steering rods, the structure of the multi-functional support frame itself can be adjusted. The support height of the rotating component can be adjusted by the support column. The worm gear can be rotated to make the worm wheel drive the support platform to rotate, thereby adjusting the direction of the mounting holes of the rotating component. The chassis can be translated by rotating the lead screw, thereby moving the rotating component along a direction perpendicular to the central axis of the steering rod, and thus distributing multiple steering rods along the same straight line.
[0024] Step 4: After arranging multiple steering rods along the same straight line using a multi-functional support frame, mounting brackets are installed on the steering rods for installing photovoltaic panels with outer frames. Synchronous shafts are fixedly installed at the same position in each row of steering rods, with the synchronous shafts located near the middle of each row of steering rods. The synchronous shafts in this row are connected in series by a push-pull rod.
[0025] Step 5: Flip and close the two fixed outer rings and fix them with bolts so that the steering rods are engaged inside the two rotating half rings. When the external drive device pushes and pulls each synchronous shaft synchronously through the push-pull rod, each synchronous shaft drives each row of steering rods to flip synchronously, so that the mounting frame drives the photovoltaic panel to adjust its direction.
[0026] Step Six: Initially or in the early morning, the photovoltaic panel faces eastward at an angle towards the sun. As the sun moves from east to west, the photovoltaic panel's orientation flips from eastward to westward. During this process, the photovoltaic panel can be cleaned once by the rubber scraper and reciprocating slider on the cleaning mechanism. When the photovoltaic panel returns to the eastward orientation, the cleaning mechanism can reset the rubber scraper and reciprocating slider after cleaning.
[0027] The working principle and beneficial effects of this invention are as follows:
[0028] 1. This invention achieves zero-energy drive and efficient dust removal by setting up a dual self-cleaning system. The first cleaning is achieved by employing a cleaning mechanism and a reset mechanism working in tandem: when the photovoltaic panel rotates from east to west, the arc-shaped abutment pushes the second insert plate to compress the reset spring, the linkage gear releases the first insert plate, and the elastic traction rope pulls the reciprocating slider, causing the rubber scraper to scrape the photovoltaic panel in one direction. The second cleaning is achieved when the photovoltaic panel resets to the east, the steering rod drives the second gear to drive the first gear, which, through the telescopic rod and connecting rod, pushes the rectangular push frame along the T-shaped slide, forcibly resetting the reciprocating slider to its starting point. During the reset process, the rubber scraper scrapes the panel again. This invention utilizes the natural rotation of the photovoltaic panel to track the sun for cleaning, requiring no additional energy or control system. It is purely mechanical transmission without electronic components, adaptable to outdoor high and low temperatures and dusty environments, and has a lower failure rate than traditional motor-driven solutions. It automatically completes two comprehensive cleaning and tracking processes plus a reset process daily, reducing dust impact, effectively improving power generation efficiency, and reducing manual maintenance.
[0029] 2. In this invention, the multi-functional support frame adopts a modular design, including support columns, a tray, a movable chassis, a worm gear mechanism, and an openable rotating assembly. By rotating the lead screw to move the chassis laterally and rotating the worm gear to adjust the rotation angle of the support platform, combined with the height adjustment of the support columns, a three-dimensional spatial adjustment capability is achieved. The rotating assembly consists of two fixed outer rings hinged together by a pivot and an inner rotating semi-ring, allowing for quick opening and closing to lock the steering rods. In case of a single support frame failure, it can be independently disassembled and repaired, avoiding the need for disassembly of the entire structure. In matrix installation, the height, horizontal position, and rotation angle of each support frame can be independently adjusted to ensure precise alignment of multiple rows of steering rods, solving the installation deviation problem caused by uneven terrain and providing excellent terrain adaptability.

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0043] Example 1
[0044] Please see Figure 1 , Figure 2 as well as Figure 3 An installation method for a single-axis tracking photovoltaic power generation bracket includes: a steering rod 4, a mounting frame 7 and a synchronous shaft 5 detachably fixed to the outside of the steering rod 4, an outer frame 2 mounted on the mounting frame 7, and a photovoltaic panel 3 mounted inside the outer frame 2. A base frame 1 is provided on the lower side of the photovoltaic panel 3. Two arc-shaped abutment rods 11 are symmetrically fixed to the top of one side of the base frame 1. Several multi-functional support frames 8 are provided on the outside of the base frame 1 to support the steering rod 4. The steering rod 4 can be rotated in the multi-functional support frames 8 by pushing the synchronous shaft 5.
[0045] Specifically, the multi-functional support frame 8 includes a support column 81 and a tray 83 fixed to the top of the support column 81. A base 85 is slidably clamped inside the tray 83, and a base 84 is fixed to one side of the base 85. The base 85 and the base 84 are integrated into one piece, and the base 84 is slidably connected to the tray 83. A horizontally arranged lead screw 88 is rotatably installed inside the tray 83. The lead screw 88 is threadedly connected to the base 84 and the base 85, that is, the lead screw 88 is threaded through the inside of the base 84 and the base 85. By rotating the lead screw 88, the base 85 and the base 84 can slide and move within the tray 83. It should be noted that the support column 81 is a height-adjustable telescopic structure, including an inner rod and an outer cylinder. The inner rod is slidably sleeved inside the outer cylinder, and the inner rod and the outer cylinder are fixedly connected by bolt compression. The top of the inner rod is fixed to the bottom of the tray 83.
[0046] Furthermore, a worm gear 87 is rotatably connected to the top of the base 84, and a worm 86 is meshed with one side of the worm gear 87. The worm 86 is rotatably connected to the inside of the chassis 85, and a support platform 89 is fixed to the top of the worm gear 87. A rotating component 82 is installed on the upper side of the support platform 89.
[0047] Furthermore, the rotating assembly 82 includes two fixed outer rings 822, which are rotatably connected at one end by a rotating shaft 823, and the other end of the two fixed outer rings 822 can be detachably fixed by bolts. A rotating half-ring 821 is rotatably sleeved on the inner side of each of the two fixed outer rings 822, and the steering rod 4 is constrained by the two rotating half-rings 821.
[0048] In this embodiment, the two fixed outer rings 822 are flipped open via the rotating shaft 823, and the steering rod 4 is placed inside the rotating semi-ring 821. The longer steering rod 4 will span several multi-functional support frames 8 simultaneously, and adjacent steering rods 4 can be connected by bolts. When the multi-functional support frames 8 are distributed in a matrix, or during the placement of the steering rods 4, the structure of the multi-functional support frames 8 can be adjusted. The support height of the rotating component 82 can be adjusted by the support column 81. By rotating the worm gear 86, the worm wheel 87 drives the support platform 89 to rotate, thereby adjusting the direction of the mounting hole of the rotating component 82. By rotating the lead screw 88, the chassis 85 can be translated, thereby moving the rotating component 82 along a direction perpendicular to the central axis of the steering rod 4, and thus distributing multiple steering rods 4 along the same straight line.
[0049] In this embodiment, multiple steering rods 4 are arranged along the same straight line using a multi-functional support frame 8. Mounting brackets 7 are installed on the steering rods 4 for mounting the photovoltaic panels 3 with outer frames 2. Synchronous shafts 5 are fixedly installed at the same position in each row of steering rods 4, with the synchronous shafts 5 located near the middle of each row. These synchronous shafts 5 are connected in series via a push-pull rod (not shown in the figure). Two fixed outer rings 822 are flipped and closed and secured with bolts, causing the steering rods 4 to engage inside the two rotating semi-rings 821. When an external drive device (not shown in the figure) pushes and pulls each synchronous shaft 5 synchronously via the push-pull rod, each synchronous shaft 5 drives each row of steering rods 4 to flip synchronously, causing the mounting brackets 7 to adjust the orientation of the photovoltaic panels 3.
[0050] Example 2
[0051] Please see Figure 1 , Figures 4 to 10 An installation method for a single-axis tracking photovoltaic power generation bracket is disclosed, including all the contents of Embodiment 1. Furthermore, a cleaning mechanism 6 is provided on the outer frame 2. The cleaning mechanism 6 includes two reciprocating sliders 62 and a rubber scraper 61 connected between the two reciprocating sliders 62. During the rotation of the photovoltaic panel 3 with the steering rod 4, the cleaning mechanism 6, in cooperation with the arc-shaped abutment rod 11, can perform a primary cleaning of the photovoltaic panel 3 using the rubber scraper 61. A reset mechanism 9 is provided between the steering rod 4 and the outer frame 2 to reset the cleaned reciprocating sliders 62 and the rubber scraper 61, achieving a secondary cleaning.
[0052] Furthermore, two right-angled grooves 65 are provided on both sides of the outer wall of the outer frame 2, and the reciprocating slider 62 is slidably connected to the right-angled grooves 65. At the two corners of the outer frame 2, fixed plates 68 extend outward and are fixedly connected. Rollers 66 are rotatably connected to the fixed plates 68. An elastic traction rope 67 slides through the inner side of the roller 66. One end of the elastic traction rope 67 is fixedly connected to the reciprocating slider 62, and the other end of the elastic traction rope 67 is connected to the outer wall of the base frame 1.
[0053] Furthermore, a limiting component 63 is provided on one side of the reciprocating slider 62. The limiting component 63 includes a first insert plate 631 and a second insert plate 632. The top of the first insert plate 631 is rounded. A sliding cavity is provided on the inner side of the outer frame 2 for the first insert plate 631 and the second insert plate 632 to slide. A return spring 633 is connected between the first insert plate 631 and the bottom of the sliding cavity, and between the second insert plate 632 and the top of the sliding cavity. The first insert plate 631 extends out of the upper outer wall of the outer frame 2, and the second insert plate 632 extends out of the lower outer wall of the outer frame 2.
[0054] Furthermore, the limiting component 63 also includes a linkage gear 635 rotatably connected inside the outer frame 2, and the outer walls of the first insert plate 631 and the second insert plate 632 on opposite sides are provided with tooth grooves 634 that mesh with the linkage gear 635.
[0055] Specifically, the reset mechanism 9 includes a second gear 94 fixedly sleeved on the outer wall of the steering rod 4, a first gear 92 meshing with one side of the second gear 94, a diagonal brace 91 fixedly connected to the top of the base frame 1, and the first gear 92 rotatably connected to the diagonal brace 91.
[0056] Furthermore, the reset mechanism 9 also includes a rectangular push frame 96, with a T-shaped slider fixedly connected to one side of the rectangular push frame 96. A T-shaped slide rail 64, which mates with the T-shaped slider, is provided on the side wall of the outer frame 2, allowing the rectangular push frame 96 to slide along the side wall of the outer frame 2. A telescopic rod 93 is fixedly connected to the outer wall of the first gear 92. One end of the telescopic rod 93 is hinged to a connecting rod 95, and the other end of the connecting rod 95 is fixedly connected to the rectangular push frame 96. It should be noted that the telescopic rod 93 is a common existing structure, and a compression spring can be built inside to achieve the telescopic function.
[0057] In this embodiment, reference Figure 1 and Figure 4 Initially, photovoltaic panel 3 faces eastward. As the sun moves from east to west, the synchronous shaft 5 is pushed, causing the steering rod 4 to rotate the mounting frame 7, thus turning photovoltaic panel 3 towards the west (e.g., Figure 9 (As shown). During this process, as the photovoltaic panel 3 rotates counterclockwise around the steering rod 4, refer to... Figure 4 and Figure 7 The outer frame 2 drives the rotating roller 66 to rotate counterclockwise via the fixed plate 68. The rotating roller 66 pulls the elastic traction rope 67, causing the elastic traction rope 67 to stretch and deform to the point where... Figure 9 As shown in the diagram, with the further rotation of photovoltaic panel 3, reference... Figure 10 The second insert plate 632 will abut against the arc-shaped abutment 11. Since the position of the arc-shaped abutment 11 is fixed, the second insert plate 632 extends inward toward the outer frame 2. (Refer to...) Figure 6 Under the action of the linkage gear 635, the first insert plate 631 moves down, removing the limit on the reciprocating slider 62. The stretched elastic traction rope 67 needs to deform and reset, thereby driving the reciprocating slider 62 to move to the right along the side wall of the outer frame 2, thereby driving the rubber scraper 61 to move to the right to wipe and clean the photovoltaic panel 3, until the reciprocating slider 62 slides to the rightmost side of the right angle slide groove 65, that is, after the photovoltaic panel 3 has completed the work of changing from east to west for a day, the photovoltaic panel 3 has achieved a self-cleaning.
[0058] In this embodiment, in order for the photovoltaic panel 3 to receive the rising sun the next day, the photovoltaic panel 3 needs to be flipped back to face east, that is, the photovoltaic panel 3 is rotated from its original position to face east. Figure 9The position shown is transformed into... Figure 4 The location shown. During this process, refer to... Figure 9 The steering rod 4 drives the photovoltaic panel 3 to rotate clockwise. The steering rod 4, through the second gear 94, drives the first gear 92 to rotate counterclockwise. The first gear 92 drives the telescopic rod 93 to rotate counterclockwise. The telescopic rod 93, through the connecting rod 95, drives the rectangular push frame 96 to slide down along the side wall of the outer frame 2. The T-shaped slider on the rectangular push frame 96 slides along the inner side of the T-shaped slide rail 64. It should be noted that at this time, the reciprocating slider 62, due to the traction of the elastic traction rope 67, is already located at the right end of the outer frame 2, that is, the reciprocating slider 62 is in contact with the left end of the rectangular push frame 96. This allows the rectangular push frame 96 to push the reciprocating slider 62 when it slides down or moves to the left along the side wall of the outer frame 2, causing the reciprocating slider 62 to slide downwards or to the left to reset. (Reference) Figure 8 When the photovoltaic panel 3 flips back to face east, the rectangular push frame 96 pushes the reciprocating slider 62 to the left end of the outer frame 2, as shown in the reference. Figure 5 and Figure 6 When the reciprocating slider 62 moves to the left to reset, it pushes the rounded end of the upper side of the first insert plate 631, causing the first insert plate 631 to slide inward to the outer frame 2 and compress the reset spring 633. When the reciprocating slider 62 slides to the left side of the first insert plate 631, the first insert plate 631 extends outward to the outer side of the outer frame 2 again under the action of the reset spring 633, thus limiting the reciprocating slider 62.
[0059] Working principle and usage process:
[0060] First, the multi-functional support frame 8 is installed in rows along a straight line at equal intervals in the work area. Then, the multi-functional support frame 8 is distributed in multiple rows according to work needs, so that the multi-functional support frame 8 is arranged in a matrix in the work area.
[0061] Next, the two fixed outer rings 822 are flipped open via the rotating shaft 823, and the steering rod 4 is placed inside the rotating semi-ring 821. The longer steering rod 4 will span several multi-functional support frames 8 simultaneously, and adjacent steering rods 4 can be connected by bolts. When the multi-functional support frames 8 are distributed in a matrix, or during the placement of the steering rods 4, the structure of the multi-functional support frames 8 can be adjusted. The support height of the rotating component 82 can be adjusted by the support column 81. By rotating the worm gear 86, the worm wheel 87 drives the support platform 89 to rotate, thereby adjusting the direction of the mounting holes of the rotating component 82. By rotating the lead screw 88, the chassis 85 can be translated, thereby moving the rotating component 82 along a direction perpendicular to the central axis of the steering rod 4, thus distributing multiple steering rods 4 along the same straight line.
[0062] Afterwards, multiple steering rods 4 are arranged along the same straight line using a multi-functional support frame 8. Mounting brackets 7 are then installed on the steering rods 4 for mounting the photovoltaic panels 3 with outer frames 2. Synchronous shafts 5 are fixedly installed at the same position in each row of steering rods 4, with the synchronous shafts 5 located near the middle of each row. These synchronous shafts 5 are connected in series via a push-pull rod. Alternatively, in existing technology, an external drive device pushes and pulls the push-pull rod, causing the synchronous shafts 5 to rotate, thus rotating the steering rods 4. This will not be elaborated upon here. The two fixed outer rings 822 are flipped and closed, and then secured with bolts, so that the steering rods 4 are engaged inside the two rotating semi-rings 821. When the external drive device pushes and pulls each synchronous shaft 5 synchronously via the push-pull rod, each synchronous shaft 5 drives each row of steering rods 4 to flip synchronously, causing the mounting brackets 7 to adjust the orientation of the photovoltaic panels 3.
[0063] Initially, or in the early morning, the photovoltaic panel 3 faces eastward at an angle towards the sun. As the sun moves from east to west, the orientation of the photovoltaic panel 3 flips from near east to near west. During this process, the rubber scraper 61 and reciprocating slider 62 on the cleaning mechanism 6 can complete one cleaning of the photovoltaic panel 3. When the orientation of the photovoltaic panel 3 returns to east, the reset mechanism 9 can reset the rubber scraper 61 and reciprocating slider 62 after cleaning, achieving a second cleaning. For details, refer to... Figure 1 and Figure 4 Initially, photovoltaic panel 3 faces eastward. As the sun moves from east to west, the synchronous shaft 5 is pushed, causing the steering rod 4 to rotate the mounting frame 7, thus turning photovoltaic panel 3 towards the west (e.g., Figure 9 (As shown). During this process, as the photovoltaic panel 3 rotates counterclockwise around the steering rod 4, refer to... Figure 4 and Figure 7 The outer frame 2 drives the rotating roller 66 to rotate counterclockwise via the fixed plate 68. The rotating roller 66 pulls the elastic traction rope 67, causing the elastic traction rope 67 to stretch and deform to the point where... Figure 9 As shown in the diagram, with the further rotation of photovoltaic panel 3, reference... Figure 10 The second insert plate 632 will abut against the arc-shaped abutment 11. Since the position of the arc-shaped abutment 11 is fixed, the second insert plate 632 extends inward toward the outer frame 2. (Refer to...) Figure 6 Under the action of the linkage gear 635, the first insert plate 631 moves down, removing the limit on the reciprocating slider 62. The stretched elastic traction rope 67 needs to deform and reset, thereby driving the reciprocating slider 62 to move to the right along the side wall of the outer frame 2, thereby driving the rubber scraper 61 to move to the right to wipe and clean the photovoltaic panel 3, until the reciprocating slider 62 slides to the rightmost side of the right angle slide groove 65, that is, after the photovoltaic panel 3 has completed the work of changing from east to west for a day, the photovoltaic panel 3 has achieved a self-cleaning.
[0064] Afterwards, in order for photovoltaic panel 3 to face the eastern sun the next day, it needs to be rotated back to face east, i.e., photovoltaic panel 3 is rotated from facing east to facing east. Figure 9 The position shown is transformed into... Figure 4 The location shown. During this process, refer to... Figure 9 The steering rod 4 drives the photovoltaic panel 3 to rotate clockwise. The steering rod 4, through the second gear 94, drives the first gear 92 to rotate counterclockwise. The first gear 92 drives the telescopic rod 93 to rotate counterclockwise. The telescopic rod 93, through the connecting rod 95, drives the rectangular push frame 96 to slide down along the side wall of the outer frame 2. The T-shaped slider on the rectangular push frame 96 slides along the inner side of the T-shaped slide rail 64. It should be noted that at this time, the reciprocating slider 62, due to the traction of the elastic traction rope 67, is already located at the right end of the outer frame 2, that is, the reciprocating slider 62 is in contact with the left end of the rectangular push frame 96. This allows the rectangular push frame 96 to push the reciprocating slider 62 when it slides down or moves to the left along the side wall of the outer frame 2, causing the reciprocating slider 62 to slide downwards or to the left to reset. (Reference) Figure 8 When the photovoltaic panel 3 flips back to face east, the rectangular push frame 96 pushes the reciprocating slider 62 to the left end of the outer frame 2, as shown in the reference. Figure 5 and Figure 6 When the reciprocating slider 62 moves to the left to reset, it pushes the rounded end of the upper side of the first insert plate 631, causing the first insert plate 631 to slide inward to the outer frame 2 and compress the reset spring 633. When the reciprocating slider 62 slides to the left side of the first insert plate 631, the first insert plate 631 extends outward to the outer side of the outer frame 2 again under the action of the reset spring 633, thus limiting the reciprocating slider 62.

4. An installation method for a single-axis tracking photovoltaic power generation bracket, characterized in that, Includes the following steps: Step 1: Install the multi-functional support frame (8) at equal intervals along a straight line in rows on the work site. Then, distribute the multi-functional support frame (8) into multiple rows according to work needs in this manner, so that the multi-functional support frame (8) is arranged in a matrix on the work site. Step 2: Open the two fixed outer rings (822) by rotating the shaft (823), place the steering rod (4) inside the rotating half ring (821), the longer steering rod (4) will span several multi-functional support frames (8) at the same time, and the two adjacent steering rods (4) can be connected by bolts, and the base frame (1) is fixed to the installation site; Step 3: When the multi-functional support frame (8) is distributed in a matrix, or when the steering rod (4) is installed, the structure of the multi-functional support frame (8) itself can be adjusted. The support height of the rotating component (82) can be adjusted by the support column (81).

Step 6: Initially or in the early morning, the photovoltaic panel (3) faces east and is tilted towards the sun. As the sun moves from east to west, the orientation of the photovoltaic panel (3) flips from east to west.
