Description

Technical Field

[0001] This invention relates to the technical field of photovoltaic power plants, and more particularly to the technical field of photovoltaic brackets, specifically a photovoltaic bracket for photovoltaic power plants that can be adjusted at multiple angles. Background Technology

[0002] A photovoltaic power station is a photovoltaic power generation system that is connected to the power grid and transmits electricity to the grid. It uses the photovoltaic effect to directly convert solar radiation energy into electrical energy through photovoltaic cell modules. As an important form of renewable energy, photovoltaic power generation is different from traditional fossil energy and has advantages such as being environmentally friendly and pollution-free, being continuously renewable, and having high conversion efficiency. A photovoltaic power generation system is mainly composed of photovoltaic cell modules, support systems, power conversion and control components, and energy storage and distribution components. As for the support system, it is responsible for the fixed placement and support of the photovoltaic cell modules. In addition, in order to maximize the reception of sunlight and improve power generation efficiency, the support system is also responsible for the angle adjustment of the photovoltaic cell modules.

[0003] For example, Chinese patent CN115765593B discloses an adjustable bracket including a base plate, an adjustable plate hinged to one end of the base plate, a support plate on the surface of the adjustable plate, a telescopic adjustment control on the surface of the base plate, and a slider at the top of the telescopic adjustment control, which is slidably connected to the surface of the adjustable plate. The adjustable bracket proposed in this invention achieves tilt angle adjustment of the adjustable plate by manipulating the telescopic adjustment control to push the adjustable plate to swing, thus expanding the adaptability range of the adjustable plate and solving the defects of traditional fixed-angle support brackets.

[0004] Based on the aforementioned patents, existing solutions, and practical application, current photovoltaic (PV) mounting systems for power plants still have some problems, such as: 1. The adjustment method of the photovoltaic bracket in the above patent involves pushing the telescopic adjustment control to make the adjustment plate hinged to the base plate flip and swing, thereby driving the photovoltaic panel to adjust the tilt angle through the adjustment plate. However, the adjustment effect achieved by the adjustment method in the above patent can only be adjusted by flipping back and forth, that is, only the pitch angle can be adjusted. Its adjustment method is relatively simple and cannot meet the needs of multi-angle and all-round adjustment, which affects the efficiency of receiving solar radiation energy throughout the year. 2. In the above-mentioned patent, the telescopic adjustment control requires manual rotation of the adjustment component to raise or lower it, and the slider is moved by the traction component. The adjustment plate is flipped and adjusted by pushing and pulling. The adjustment method of the photovoltaic bracket in the above-mentioned patent is similar to the existing photovoltaic bracket adjustment method that uses sliding and bolt fixing. Both require manual adjustment, which cannot meet the purpose of automatic adjustment and affects the convenience of operation.

[0005] Therefore, we propose a photovoltaic support structure for photovoltaic power plants that can be adjusted at multiple angles to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a photovoltaic support for photovoltaic power plants that can be adjusted at multiple angles, so as to solve the problem that the adjustment methods proposed in the background art are relatively simple, which cannot meet the purpose of automatic adjustment and cannot meet the needs of multi-angle and all-round adjustment, thus affecting the efficiency of solar radiation energy reception throughout the year.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic support bracket for a photovoltaic power station that can be adjusted at multiple angles, comprising: A support box, wherein a tube frame connected to the box cavity is vertically and downwardly arranged at the middle position of the lower side wall of the support box; Also includes: The column component forms a lifting structure on the support box by being driven by an electric telescopic rod. The photovoltaic panel body automatically enters and exits the box cavity of the support box through the lifting movement of the column component. The front and rear side walls of the box opening are equipped with openable and closable protective doors. An adjustment mechanism is provided at the connection between the photovoltaic panel body and the column component. It can operate the photovoltaic panel body to automatically adjust the pitch angle and the azimuth angle.

[0008] Preferably, the adjustment mechanism includes a main adjustment seat that can rotate on the disc portion of the tubular component and a secondary adjustment seat that can flip on the main adjustment seat. The rotation center of the main adjustment seat coincides with the ring center of the circular toothed ring, and the circular toothed ring is fixedly connected to the disc portion of the tubular component. A worm gear is rotatably connected in the upper end cavity of the main adjustment seat, and the middle end shaft cover of the worm gear is fixedly connected to the secondary adjustment seat. The connecting frame in the secondary adjustment seat is fixedly connected to the back plate of the photovoltaic panel body.

[0009] Preferably, a worm gear that meshes with a worm wheel is rotatably connected to the middle cavity of the main adjusting seat, and a linkage gear that meshes with a circular gear ring is rotatably connected to the left end cavity of the main adjusting seat.

[0010] Preferably, a spline groove is provided inside the central shaft tube of the linkage gear, and the left section of the spline groove is engaged with a spline transmission rod rotatably connected in the main adjustment seat, and the spline transmission rod is driven to rotate by a servo motor fixed to the main adjustment seat. The right section of the spline groove is connected to the spline head by a snap-fit ​​mechanism, and the spline head is an integral structure located at the left end of the worm gear.

[0011] Preferably, the linkage gear forms a sliding structure within the main adjusting seat, and the linkage gear is used for the individual driving of the worm gear or for the individual driving of the circular gear ring. The left end of the central shaft tube of the linkage gear is rotatably connected to a connecting block that can slide synchronously with it, and the connecting block is driven to slide by a telescopic electromagnet fixed to the main adjusting seat.

[0012] Preferably, the protective door is connected to the side of the bracket box opening via a round shaft for assisted flipping, and a torsion spring is installed at the flipping connection between the protective door and the bracket box. A drive mechanism is provided at the connection between the protective door and the bracket box, and the protective door is automatically opened and closed by operating the drive mechanism.

[0013] Preferably, the drive mechanism includes a driven gear that rotates synchronously with the round shaft in the protective door, a toothed belt that pulls the driven gear to rotate, a drive gear for winding the toothed belt, and a rack for driving the drive gear to rotate. The driven gear is fixed to the middle of the round shaft in the protective door, and the driven gear forms a rotating structure inside the side of the box opening in the support box. The upper end of the toothed belt is fixed to the driven gear, and the two are wound around and meshed together. The two tapes at the lower end of the toothed belt are respectively fixed to the two ends of the drive gear, and the two are also wound around and meshed together. The drive gear forms a rotating structure inside the lower side wall of the support box, and the middle of the drive gear is meshed with the rack that is slidably connected inside the lower side wall of the support box. The toothed belt is wound around the guide wheel in the middle, and the guide wheel forms a rotating structure inside the lower side wall of the support box.

[0014] Preferably, a return spring is installed at the sliding connection between the rack frame and the support box. The semi-circular end of the rack frame is connected to the push bar, which is integrally set on the column component, by a pressing method. Both the upper and lower ends of the push bar are provided with inclined sidewalls, and the upper inclined sidewall of the push bar and the lower inclined sidewall are arranged in opposite directions.

[0015] Preferably, a water spray frame is fixed to the inner panel of the protective door to rinse the photovoltaic panel body. The front, back, left and right sides of the photovoltaic panel body correspond to the front, back, left and right sides of the water collection tank, and the water collection tank is set in the cavity of the support box. Drainage holes are opened at equal intervals on the lower side wall of the water collection tank.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: the photovoltaic support for the photovoltaic power station that can be adjusted at multiple angles can meet the needs of multi-angle and all-round automatic adjustment in addition to the adjustment of pitch angle, optimize the reception efficiency of solar radiation energy throughout the year, and achieve shading protection for photovoltaic panels in the face of severe environments such as heavy rain, strong wind and hail. 1. Through the meshing transmission between the worm gear and the worm, the auxiliary adjustment seat drives the photovoltaic panel body to form a flipping structure on the main adjustment seat, thereby adjusting the pitch angle of the photovoltaic panel body. In addition, through the meshing transmission between the linkage gear and the circular gear ring, the main adjustment seat drives the auxiliary adjustment seat and the photovoltaic panel body to form a rotating structure on the column component, thereby adjusting the azimuth angle of the photovoltaic panel body. Unlike a single adjustment method, this method combines pitch angle adjustment with azimuth angle adjustment to meet the needs of multi-angle and all-round adjustment, optimize the annual solar radiation energy reception efficiency, and effectively improve power generation efficiency. Furthermore, the telescopic electromagnet slides forward and backward via a linkage block pushing and pulling the linkage gear. When the linkage gear slides forward and engages with the worm, the servo motor drives the linkage gear to rotate via the spline transmission rod, thereby driving the worm gear to rotate independently and adjusting the pitch angle of the photovoltaic panel. When the linkage gear slides backward and engages with the circular gear ring, the servo motor drives the linkage gear to rotate via the spline transmission rod, thereby driving the circular gear ring to rotate independently and adjusting the azimuth angle of the photovoltaic panel. This achieves the purpose of fully automatic adjustment of both pitch and azimuth angles, making the operation more convenient. 2. The bracket box is equipped with a protective door that can be flipped open and closed. After the photovoltaic panel body enters the cavity of the bracket box, the protective door flips and closes at the opening of the bracket box. The closed protective door and the bracket box form a complete protective box. In the face of severe environments such as heavy rain, strong winds and hail, the photovoltaic panel is shielded and protected, and the photovoltaic panel is prevented from being damaged by external impact. Furthermore, when the tubular component moves the photovoltaic panel body out of the bracket box cavity, the pushing action of the push bar on the rack frame drives the drive gear to rotate. The drive gear then winds up the toothed belt and pulls the driven gear, causing the protective door to automatically flip and unfold on the bracket box. When the tubular component moves the photovoltaic panel body into the bracket box cavity, the push bar loses its pushing action on the rack frame. The elastic deformation of the return spring and torsion spring resets the drive gear, causing it to rotate and unwind the toothed belt. The toothed belt then loses its pulling action on the driven gear, causing the protective door to automatically flip and close on the bracket box. Through the linkage structure, the automatic flipping and unfolding or automatic flipping and closing of the protective door is achieved simultaneously when the photovoltaic panel body enters and exits the bracket box, ensuring ease of operation. Furthermore, after the photovoltaic panel body enters the cavity of the bracket box, the protective door flips and closes on the bracket box, so that the water spray rack is directly above the photovoltaic panel body. Through the setting of the water spray rack, the entire surface of the photovoltaic panel body can meet the needs of automatic rinsing and cleaning. The cleaning wastewater is centrally discharged through the water collection tank, which effectively improves the functionality of the photovoltaic bracket. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Example 1:

[0020] This invention provides a technical solution: a photovoltaic support for a photovoltaic power station that can be adjusted at multiple angles. This addresses the problem that photovoltaic supports cannot be automatically adjusted, and their adjustment methods are relatively limited, only allowing for pitch angle adjustment and unable to coordinate with azimuth angle adjustment. This fails to meet the needs of multi-angle, all-around adjustment, affecting the efficiency of solar radiation reception throughout the year. When the linkage gear 12 engages with the worm gear 11, it drives the worm gear 11 to rotate. Through the meshing transmission between the worm wheel 10 and the worm gear 11, the auxiliary adjustment seat 8 drives the photovoltaic panel body 4 to rotate, thus automatically adjusting the pitch angle of the photovoltaic panel body 4. When the linkage gear 12 engages with the circular gear ring 9, through the meshing transmission between the linkage gear 12 and the circular gear ring 9, the main adjustment seat 7 drives the auxiliary adjustment seat 8 and the photovoltaic panel body 4 to rotate, thus automatically adjusting the azimuth angle of the photovoltaic panel body 4.

[0021] This technical solution: Please refer to Figures 1-7 A photovoltaic support structure for a photovoltaic power station with multi-angle adjustable features includes a support box 1. Integrated brackets are installed at the four corners of the lower side wall of the support box 1. The brackets in the support box 1 are fixedly installed on a cement base (which is pre-cast at the designated installation position of the photovoltaic panels) using bolts, thus fixing the support box 1 at the photovoltaic panel installation position. A tubular frame 101, connected to the box cavity, is vertically installed at the middle of the lower side wall of the support box 1. After the support box 1 is placed on the cement base, the tubular frame 101 is inserted into a pre-reserved tubular groove in the cement base (the tubular groove is pre-reserved during the casting of the cement base). It also includes a column component 2 and an adjustment mechanism 6. The column component 2 forms a lifting structure on the support box 1 by being driven by an electric telescopic rod 3. The photovoltaic panel body 4 is externally connected to a photovoltaic grid-connected box (wherein the photovoltaic grid-connected box is existing technology and will not be described in detail in the manual) via a spring wire. After installation, the photovoltaic panel body 4 is positioned directly above the column component 2, and its middle position corresponds to the column component 2. The photovoltaic panel body 4 automatically enters and exits the box cavity of the support box 1 by the lifting movement of the column component 2. The upper side wall of the support box 1 is in an open state, which is set as the box opening. The front and rear side walls of the box opening in the support box 1 are provided with openable and closable protective doors 5. The adjustment mechanism 6 is set at the connection between the photovoltaic panel body 4 and the column component 2 and is used for the assembly connection between the photovoltaic panel body 4 and the column component 2. It can operate the photovoltaic panel body 4 to automatically adjust the pitch angle and the azimuth angle.

[0022] Specifically, in this technical solution, when performing the operation of moving the photovoltaic panel body 4 out of or into the cavity of the support box 1, according to... Figure 1 and Figure 2 As shown, before the photovoltaic panel body 4 is moved out of the box cavity of the bracket box 1, the protective doors 5 on the front and rear side walls of the box opening of the bracket box 1 are flipped and unfolded. Since the electric telescopic rod 3 is installed and inserted into the column cavity of the column component 2, and it is fixedly connected to the column cavity wall of the column component 2 by bolts, and the output end is fixedly connected to the lower tube cavity wall of the tube frame 101 by bolts, and since the electric telescopic rod 3 is connected to the control board (where the control board is existing technology and will not be described in detail in the manual) through the spring wire, the electric telescopic rod 3 is started to extend and operate, pushing the column component 2 to move upward. Since the adjustment mechanism 6 is used for the assembly connection between the photovoltaic panel body 4 and the tube column 2, the photovoltaic panel body 4 and the tube column 2 form a synchronous lifting and lowering motion structure through the connection action of the adjustment mechanism 6. Since the tube frame 101 is fixedly welded to the middle position of the lower side wall of the support box 1 in a vertical downward state, its cavity is connected to the cavity of the support box 1. Since the tube column 2 is installed and movably inserted into the cavity of the tube frame 101, the tube column 2 slides upward in the cavity of the tube frame 101 after being pushed. That is, the tube column 2 drives the photovoltaic panel body 4 to move upward on the support box 1 through the electric telescopic rod 3, and the photovoltaic panel body 4 is moved out of the cavity of the support box 1. Conversely, according to the above, the electric telescopic rod 3 is activated to retract and operate, pulling the column component 2 downward. Driven by the electric telescopic rod 3, the column component 2 drives the photovoltaic panel body 4 to descend on the bracket box 1. The photovoltaic panel body 4 is then operated to enter the cavity of the bracket box 1, and the protective doors 5 on the front and rear side walls at the opening of the bracket box 1 are flipped and closed.

[0023] Specifically, in this technical solution, the linkage gear 12 is operated to rotate, according to... Figure 3 and Figure 7 As shown, a motor protective shell is fixedly installed on the left end of the main adjustment seat 7 by bolts. Since the servo motor 14 is externally connected to the control motherboard (where the control motherboard is existing technology and will not be described in detail in the manual) through spring wires, and since the servo motor 14 is placed inside the motor protective shell in the main adjustment seat 7, it is fixedly connected to the left end shell wall of the main adjustment seat 7 by bolts, and its output end is fixedly inserted into the left end of the spline transmission rod 13. Since the left section of the spline transmission rod 13 is set in a round rod structure, bearings are fixedly clamped at equal intervals on the round rod body of its left section. After the spline transmission rod 13 is installed, the round rod body of its left section, together with the bearings, is inserted into the cavity wall of the left end seat cavity of the main adjustment seat 7. When the servo motor 14 is started to operate, the spline transmission rod 13 is driven by the servo motor 14 to rotate in the left end seat cavity of the main adjustment seat 7. Since the linkage gear 12 has an integrated shaft tube at its center, the linkage gear 12 is placed in the left end cavity of the main adjustment seat 7 after it is installed, and the two ends of the shaft tube are respectively movably inserted into the two side cavity walls of the main adjustment seat 7, so that the linkage gear 12 is positioned in a movable state within the main adjustment seat 7. Because a spline groove 1201 is provided inside the central shaft tube of the linkage gear 12, and the center of the spline groove 1201 coincides with the center of the central shaft tube of the linkage gear 12, and because the right section of the spline transmission rod 13 is set in a spline-shaped structure, after the spline transmission rod 13 is installed, the spline-shaped rod of its right section is movably inserted into the central shaft tube of the linkage gear 12. That is, the spline-shaped rod of the right section of the spline transmission rod 13 is engaged with the left section of the spline groove 1201. When the spline transmission rod 13 is driven to rotate, the linkage gear 12 is driven to move synchronously through the engagement between the spline transmission rod 13 and the spline groove 1201, so that the linkage gear 12 rotates in the left end cavity of the main adjusting seat 7.

[0024] Specifically, in this technical solution, during the position-changing operation of the linkage gear 12, the linkage gear 12 is individually connected to the worm gear 11, or the linkage gear 12 is individually connected to the circular gear ring 9, according to... Figure 3 , Figure 6 and Figure 7As shown, the telescopic electromagnet 16 is externally connected to the control board (which is existing technology and will not be described in detail in the manual) via a spring wire. After installation, the telescopic electromagnet 16 is fixedly connected to the upper cavity wall of the left end of the main adjustment seat 7 by bolts, and its output end is plugged into and fixedly connected to the upper end of the linkage block 15 by bolts. Furthermore, after installation, the linkage block 15 is movably locked within the left end cavity of the main adjustment seat 7. Its square structure allows the linkage block 15 to be positioned in a movable state within the main adjustment seat 7, thus limiting its movement. The control can only perform linear sliding. Since the lower end of the linkage block 15 is fixedly connected to a bearing, after the linkage block 15 is installed, its lower end, along with the bearing, is movably sleeved on the left end of the shaft tube of the linkage gear 12. The two form a synchronous sliding structure. When the telescopic electromagnet 16 is activated to extend and operate, the linkage block 15 is driven by the telescopic electromagnet 16 to slide in the left end cavity of the main adjustment seat 7. The linkage block 15 drives the linkage gear 12 to slide synchronously, so that the linkage gear 12 slides in the forward direction in the left end cavity of the main adjustment seat 7. Since the spline head 1101 is an integral structure set at the left end of the worm 11, the center of the spline head 1101, the center of the worm 11, and the core of the tube of the central shaft of the linkage gear 12 are all on the same horizontal central axis. After the linkage gear 12 is driven to slide forward, the right section of the spline groove 1201 is connected to the spline head 1101 by a snap-fit ​​method, completing the docking between the linkage gear 12 and the worm 11. At this time, the linkage gear 12 loses its meshing connection with the circular tooth ring 9. That is, the linkage gear 12 and the worm 11 are docked separately, and when the linkage gear 12 rotates, it only drives the worm 11 alone. Conversely, when the telescopic electromagnet 16 is activated and retracted, the linkage gear 12 is driven to slide synchronously through the linkage block 15. This causes the linkage gear 12 to slide in reverse within the left end cavity of the main adjusting seat 7. Since the lower side of the main adjusting seat 7 has an annular groove with the same center as its central shaft, and this annular groove is connected to the left end cavity of the main adjusting seat 7, the circular toothed ring 9 is inserted movably into the annular groove of the main adjusting seat 7 after being installed. After the linkage gear 12 is driven to slide in reverse, the linkage gear 12 and the circular toothed ring 9 mesh together, completing the docking between the linkage gear 12 and the circular toothed ring 9. At this time, the spline groove 1201 and the spline head 1101 lose engagement, that is, the linkage gear 12 and the circular toothed ring 9 are docked separately, and the rotation of the linkage gear 12 only drives the circular toothed ring 9.

[0025] Meanwhile, in the above technical solutions, according to Figure 3 and Figure 7As shown, since the length of the part where the spline drive rod 13 engages with the linkage gear 12 is greater than the maximum sliding distance of the linkage gear 12, and since the linkage gear 12 forms a sliding structure on the spline-shaped rod body of the right section of the spline drive rod 13, when the linkage gear 12 slides to switch between driving the worm gear 11 and driving the circular gear ring 9, the left section of the spline groove 1201 is always engaged with the spline drive rod 13, that is, the spline drive rod 13 can always drive the linkage gear 12 to rotate.

[0026] Meanwhile, in the above technical solutions, according to Figure 3 and Figure 7 As shown, since the lower end of the linkage block 15 is fixedly connected to a bearing, after the linkage block 15 is installed, its lower end, along with the bearing, is movably sleeved on the left end of the central shaft tube of the linkage gear 12, so that the linkage block 15 forms a rotating structure on the left end of the central shaft tube of the linkage gear 12. That is, when the spline transmission rod 13 drives the linkage gear 12 to rotate, the linkage block 15 will not affect the rotation of the linkage gear 12.

[0027] Specifically, in this technical solution, the tilt angle of the photovoltaic panel body 4 is automatically adjusted via the adjustment mechanism 6, according to... Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, when the telescopic electromagnet 16 is started to extend and operate, the linkage block 15 pushes the linkage gear 12 to slide forward, so that the linkage gear 12 and the worm gear 11 are individually connected. When the servo motor 14 is started to operate, the spline transmission rod 13 drives the linkage gear 12 to rotate. Through the locking action between the spline groove 1201 and the spline head 1101, the worm gear 11 is driven to rotate. Since bearings are fixedly engaged at both ends of the worm 11, the worm 11 is movably inserted into the middle cavity of the main adjusting seat 7 after installation, and its two ends are respectively connected with bearings and movably inserted into the side cavity walls of the main adjusting seat 7. When driven, the worm 11 rotates in the middle cavity of the main adjusting seat 7. Because the worm gear 10 has an integrated shaft at its center, with bearings fixedly attached to both ends of the shaft, the worm gear 10 is movably mounted in the upper cavity of the main adjusting seat 7 after installation. The two ends of the shaft, along with bearings, are movably inserted into the side cavity walls of the main adjusting seat 7. Furthermore, because the lower side of the worm gear 10 is meshed with the worm 11, the worm 11 is driven to rotate. Through the meshing action between the worm 11 and the worm gear 10, the worm gear 10 rotates in the upper cavity of the main adjusting seat 7. Since both ends of the worm gear 10's central shaft are snapped and fixed with "T"-shaped end caps by bolts, after the worm gear 10 is installed, the two ends of the shaft and the end caps respectively move through the two side cavity walls of the main adjusting seat 7 and extend outward. The end cap of the worm gear 10 is set with a square structure at its end, and after docking with the central shaft of the worm gear 10, the two form a synchronous rotation structure. Since the auxiliary adjusting seat 8 is installed and is movably locked on the upper side of the main adjusting seat 7, and the front and rear "T"-shaped end caps of the worm gear 10 are respectively inserted and fixedly connected to the front and rear sides of the auxiliary adjusting seat 8 by bolts, the auxiliary adjusting seat 8 is positioned on the main adjusting seat 7 in a movable state. After the worm gear 10 is driven to rotate, it drives the auxiliary adjusting seat 8 to rotate synchronously, so that the auxiliary adjusting seat 8 flips on the main adjusting seat 7. Since the upper side of the auxiliary adjustment seat 8 is equipped with an integrated "+" shaped connecting frame, after the auxiliary adjustment seat 8 is connected to the photovoltaic panel body 4, the front, back, left and right corners of the "+" shaped connecting frame in the auxiliary adjustment seat 8 are all fixedly connected to the back plate of the photovoltaic panel body 4 by bolts. After the auxiliary adjustment seat 8 is driven to flip, it drives the photovoltaic panel body 4 to perform synchronous flipping movement, that is, to automatically adjust the pitch angle of the photovoltaic panel body 4.

[0028] Meanwhile, in the above technical solutions, according to Figure 3 and Figure 6 As shown, after the photovoltaic panel body 4 completes the automatic adjustment of the pitch angle, the linkage gear 12 loses its connection with the worm gear 11 after the position is changed. The self-locking characteristic between the worm gear 11 and the worm wheel 10 is used to lock the worm wheel 10 after it rotates, that is, the automatic locking of the photovoltaic panel body 4 after the pitch angle is adjusted is completed.

[0029] Specifically, in this technical solution, the orientation angle of the photovoltaic panel body 4 is automatically adjusted by the adjustment mechanism 6, according to... Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, when the telescopic electromagnet 16 is activated to retract and operate, the linkage block 15 pulls the linkage gear 12 to perform reverse reset sliding, so that the linkage gear 12 is individually connected to the circular tooth ring 9. The servo motor 14 is activated to operate, so that the spline transmission rod 13 drives the linkage gear 12 to rotate. Because the upper end of the column component 2 is provided with an integrated disc portion, the center of the disc portion and the center of the column are on the same vertical central axis. After the column component 2 is installed, its upper end, along with the disc portion, is inserted into the cavity of the support box 1. Also, because the lower side of the main adjustment seat 7 is provided with an integrated shaft portion, the longitudinal section of the shaft portion is "T" shaped, and both the upper and lower ends of the shaft portion are fixedly clamped with bearings. Furthermore, the axis of the shaft portion coincides with the center of the disc portion in the column component 2. After the main adjustment seat 7 is installed, the shaft portion along with the bearing is movably clamped in the disc portion at the upper end of the column component 2. Through the special "T" shaped structure of the shaft portion in the main adjustment seat 7, the main adjustment seat 7 is positioned in a movable state on the disc portion in the column component 2. Since the circular toothed ring 9 is fitted onto the disc portion of the column component 2 after installation and fixed with bolts, the center of the circular toothed ring 9 coincides with the rotation center of the main adjusting seat 7. Furthermore, after the disc portion of the column component 2 is connected to the main adjusting seat 7, the circular toothed ring 9 is movably inserted into the annular groove of the main adjusting seat 7. That is, when the main adjusting seat 7 rotates on the disc portion of the column component 2, the annular groove of the main adjusting seat 7 provides rotational space for the circular toothed ring 9. Additionally, since the circular toothed ring 9 is meshed with the linkage gear 12, the linkage gear 12, driven to rotate, rotates around the circular toothed ring 9 through the meshing connection between the circular toothed ring 9 and the linkage gear 12. This causes the main adjusting seat 7 to rotate on the disc portion of the column component 2, driving the auxiliary adjusting seat 8 and the photovoltaic panel body 4 to rotate synchronously, thus automatically adjusting the orientation angle of the photovoltaic panel body 4.

[0030] Meanwhile, in the above technical solutions, according to Figure 3 and Figure 6 As shown, after the photovoltaic panel body 4 completes the automatic adjustment of the orientation angle, the linkage gear 12, after being repositioned, only engages with the circular gear ring 9. Since the servo motor 14 has an electromagnetic brake function for locking the motor shaft (the electromagnetic brake is existing technology and will not be described in detail in the manual), through the locking action between the spline transmission rod 13 and the spline groove 1201, after the servo motor 14 is locked, the linkage gear 12 is synchronously locked, that is, the circular gear ring 9 is locked, and the automatic locking after the orientation angle adjustment of the photovoltaic panel body 4 is completed. Example 2:

[0031] Based on Embodiment 1, please refer to the following: Figures 8-13The technical solution shown is highly susceptible to damage to photovoltaic panels from external impacts in harsh environments such as heavy rain, strong winds, and hail. However, existing photovoltaic support systems are functionally limited and cannot provide adequate shading and protection for photovoltaic panels in such conditions, affecting their applicability. Furthermore, photovoltaic panels exposed to the external environment for extended periods are prone to accumulating dust and other debris, causing contamination. Existing photovoltaic support systems also fail to meet the requirements for automatic cleaning of photovoltaic panels. To address the aforementioned issue of limited functionality in photovoltaic support systems, a drive mechanism 18 is implemented. When the column component 2 rises, the operating... When the photovoltaic panel body 4 is moved out of the cavity of the bracket box 1, the protective door 5 is automatically opened first, and then the protective door 5 is automatically closed. When the column component 2 moves down and the photovoltaic panel body 4 enters the cavity of the bracket box 1, the protective door 5 is automatically opened first, and then the protective door 5 is automatically closed. The closed protective door 5 and the bracket box 1 form a complete protective box to protect the photovoltaic panel body 4. In addition, a water spray rack 25 is installed on the protective door 5 so that the photovoltaic panel body 4 can be rinsed and cleaned after entering the cavity of the bracket box 1.

[0032] Specifically, in this technical solution, the automatic opening and closing operation of the protective door 5 is performed by the drive mechanism 18, according to... Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, a drive mechanism 18 is provided at the connection between the protective door 5 and the bracket box 1. The drive mechanism 18 is symmetrically arranged about the vertical central axis of the bracket box 1. The two drive mechanisms 18 correspond to the two protective doors 5 respectively and are used to operate the opening and closing movements of the two protective doors 5. Since the tubular component 2 has an integrated structure with push bars 201, the push bars 201 are symmetrically arranged about the vertical central axis of the tubular component 2. The two push bars 201 correspond to two drive mechanisms 18 respectively, which are used to operate the sliding movement of the two rack frames 22. After the tubular component 2 is connected to the tubular shell frame 101, the push bars 201 are movably locked in the tubular shell frame 101. With the limiting assistance of the push bars 201, the tubular component 2 can only slide linearly in the tubular shell frame 101. Since the upper end of the push bar 201 is provided with an inclined sidewall, the thickness of the push bar 201 is equal to the maximum sliding distance of the rack frame 22. Since the end of the rack frame 22 facing the column member 2 is set with a semi-circular structure, when the column member 2 initially moves upward and the photovoltaic panel body 4 is moved out of the box cavity of the bracket box 1, the push bar 201 slides upward in the tube cavity of the tube frame 101, so that the upper inclined sidewall of the push bar 201 is connected to the semi-circular end of the rack frame 22 by pressing, and the semi-circular end of the rack frame 22 slides along the upper inclined sidewall of the push bar 201 onto the push bar 201. At this time, the rack frame 22 is pushed by the push bar 201. Because an integrated limiting block is provided in the middle cavity of the lower side wall of the support box 1, and because a through-shaped sliding groove is provided in the middle of the rack frame 22, the rack frame 22 is movably locked in the middle cavity of the lower side wall of the support box 1 after being installed, and the limiting block in the support box 1 is movably inserted into the sliding groove of the rack frame 22, so that the rack frame 22 is positioned in a movable state in the support box 1, and the rack frame 22 slides in the lower side wall of the support box 1 after being pushed. Because a spring compartment is provided in the middle of the limiting block in the bracket box 1, and because a return spring 24 is installed at the sliding connection between the rack frame 22 and the bracket box 1, the return spring 24 is movably inserted into the spring compartment of the limiting block in the bracket box 1 after it is installed. One end of the return spring 24 presses against the wall of the spring compartment in the bracket box 1, and the other end of the return spring 24 presses against the wall of the sliding groove in the rack frame 22. After the rack frame 22 is pushed and slid, the return spring 24 is squeezed and undergoes elastic deformation. Since a shaft column is movably inserted at the center of the drive gear 21, with both ends of the shaft column movably inserted through the two sides of the drive gear 21 and extending outward, and a bearing is provided at the insertion connection between the shaft column and the drive gear 21, the drive gear 21 is placed in the middle cavity of the lower side wall of the support box 1 after being installed. The two ends of the shaft column are respectively inserted and fixed to the two side cavity walls of the lower side wall of the support box 1 by bolts. The drive gear 21 forms a rotating structure in the middle cavity of the lower side wall of the support box 1 with the assistance of the shaft column. Since the rack frame 22 is meshed with the middle of the drive gear 21, after the rack frame 22 is pushed and slid, the drive gear 21 rotates in the lower side wall of the support box 1 through the meshing action between the rack frame 22 and the drive gear 21. Because the lower end of the toothed belt 20 has a "U"-shaped structure with a slot, it is divided into two belts. After the toothed belt 20 is installed, the lower ends of the two belts are fixed to the two ends of the drive gear 21 by bolts. The lower ends of the two belts are wound around the two ends of the drive gear 21, and the teeth on them mesh with each other. Since the width of the rack frame 22 is smaller than the distance between the two belts at the lower end of the toothed belt 20, the rack frame 22 and the toothed belt 20 can be staggered to avoid interference between the rack frame 22 and the drive gear 21 when they mesh and the drive gear 21 and the toothed belt 20 when they mesh. After the drive gear 21 is driven to rotate, the two belts at the lower end of the toothed belt 20 are wound around and meshed with the two ends of the drive gear 21, which winds up the toothed belt 20 and pulls the toothed belt 20 to move. Since a shaft column is movably inserted at the center of the guide wheel 23, with both ends of the shaft column extending outwards through both sides of the guide wheel 23, and a bearing is provided at the insertion connection between the shaft column and the guide wheel 23, the guide wheel 23 is placed in the middle cavity of the lower side wall of the support box 1 after installation. The two ends of the shaft column are respectively inserted and fixed to the side cavity walls of the lower side wall of the support box 1 with bolts. The guide wheel 23 forms a rotating structure in the middle cavity of the lower side wall of the support box 1 with the assistance of the shaft column. Since the toothed belt 20 is wound around the guide wheel 23 in the middle, the guide wheel 23 is used to assist the toothed belt 20 to pass through the middle cavity on the side of the box opening of the support box 1 to the middle cavity of the lower side wall of the support box 1. After the toothed belt 20 is pulled, the guide wheel 23 rotates in the lower side wall of the support box 1, assisting the toothed belt 20 to be pulled smoothly. Since the toothed belt 20 is installed and its upper end is fixedly connected to the driven gear 19 by bolts, and its upper end is wrapped around the driven gear 19, the teeth on the two mesh with each other. When the toothed belt 20 is pulled, the upper end of the toothed belt 20 is wrapped around and meshed with the driven gear 19, pulling the driven gear 19, causing the driven gear 19 to rotate inside the side of the box opening in the bracket box 1. Because the protective door 5 is inserted into the outer side and fixedly connected to the round shaft rod by bolts, and because the driven gear 19 is placed in the middle groove of the side of the box opening in the support box 1, and is sleeved and fixedly connected to the middle of the round shaft rod in the protective door 5, after the driven gear 19 is pulled and rotated, it drives the round shaft rod in the protective door 5 to form a synchronous rotation structure in the middle groove of the side of the box opening in the support box 1. Because the protective door 5 has bearings fixedly fastened at equal intervals on the round shaft, after the protective door 5 is installed, it is movably fastened to the side of the box opening in the bracket box 1. The round shaft, along with the bearings, is movably inserted into the side of the box opening in the bracket box 1. Furthermore, because the protective door 5 has spring compartments at both the left and right ends facing outwards, and the left and right sides of the side of the box opening in the bracket box 1 are fastened and fixedly connected with end caps by bolts, after the protective door 5 is installed and docked with the bracket box 1, the two end caps of the bracket box 1 are movably inserted into the two spring compartments of the protective door 5, so that the protective door 5 is positioned in a movable state on the bracket box 1. Because a torsion spring 17 is installed at the flip connection between the protective door 5 and the support box 1, the torsion spring 17 is symmetrically arranged about the vertical central axis of the linkage block 15. The two torsion springs 17 are respectively placed in the two spring chambers of the linkage block 15. After the torsion spring 17 is installed, it is movably inserted into the spring chamber of the linkage block 15. One end of it is fixedly clamped to the wall of the spring chamber in the linkage block 15, and the other end is fixedly clamped to the end cap in the support box 1. After the round shaft rod in the protective door 5 rotates synchronously with the driven gear 19, the protective door 5 is automatically flipped and unfolded on the side of the box opening in the support box 1 with the assistance of the round shaft rod, and the torsion spring 17 is subjected to force and undergoes elastic deformation. Based on the above, when the column component 2 continues to rise, the semi-circular end of the rack frame 22 slides along the push bar 201 to ensure that the rack frame 22 is pushed, that is, to ensure that the protective door 5 is in a flipped and unfolded state on the bracket box 1, so as not to affect the upward movement of the photovoltaic panel body 4. Based on the above, when the column component 2 completes its upward movement, since the lower end of the push bar 201 is provided with an inclined sidewall, and the upper inclined sidewall of the push bar 201 is set in the opposite direction to its lower inclined sidewall, the semi-circular end of the rack frame 22 slides out of the push bar 201 along the lower inclined sidewall of the push bar 201, so that the push bar 201 loses its pushing effect on the rack frame 22. The rack frame 22 is reset by the elastic deformation of the return spring 24, and the rack frame 22 is reset and slids in the lower side wall of the support box 1. Through the meshing action between the rack frame 22 and the drive gear 21, the drive gear 21 is reset and rotated in the lower side wall of the support box 1, and the drive gear 21 unwinds the toothed belt 20. With the assistance of the guide wheel 23, the toothed belt 20 loses its pull on the driven gear 19. With the elastic deformation of the torsion spring 17, the protective door 5 is automatically flipped and closed at the side of the box opening in the support box 1 by the assistance of the round shaft rod. Conversely, when the column component 2 initially descends, the semi-circular end of the rack frame 22 slides along the lower inclined side wall of the pusher bar 201 onto the pusher bar 201, causing the rack frame 22 to be pushed. Relying on the transmission of the drive gear 21, the toothed belt 20, and the driven gear 19, the protective door 5 automatically flips and unfolds on the support box 1. When the column component 2 continues to descend, the semi-circular end of the rack frame 22 slides along the pusher bar 201, ensuring that the rack frame 22 is in a pushed state, that is, ensuring that the protective door 5 is in a flipped and unfolded state on the support box 1, without affecting the descent movement of the photovoltaic panel body 4. When the rack frame 22 completes its descent, the semi-circular end of the rack frame 22 slides out of the pusher bar 201 along the upper inclined side wall of the pusher bar 201, and the rack frame 22 loses its pushing effect, causing the protective door 5 to automatically flip and close on the support box 1.

[0033] Meanwhile, in the above technical solutions, according to Figure 8 and Figure 13As shown, since the upper ends of the left and right side walls at the opening of the support box 1 are vertically provided with integrated limiting strips, the left and right limiting strips are connected to the left and right sides of the protective door 5 by means of overlapping and fitting. The limiting strips in the support box 1 support the flip-closed protective door 5, so that the flip-closed protective door 5 is set in a horizontal state at the opening of the support box 1.

[0034] Meanwhile, in the above technical solutions, according to Figure 8 As shown, a through-hole is provided in the middle of the inner side of the protective door 5. The slot in the protective door 5 is used for the connection between the protective door 5 and the column component 2. After the column component 2 moves upward, it prevents the column component 2 from blocking the closing of the protective door 5. In addition, a rubber curtain baffle is fixedly connected to the slot in the protective door 5 by bolts to cover the slot in the protective door 5. At the same time, it will not affect the connection between the column component 2 and the slot in the protective door 5.

[0035] Specifically, in this technical solution, the photovoltaic panel body 4 is protected by the bracket box 1, according to... Figure 8 and Figure 13 As shown, the column component 2 moves downward, driving the photovoltaic panel body 4 into the cavity of the bracket box 1. Then, the protective door 5 is automatically flipped and closed by the drive mechanism 18. The protective door 5 seals the opening of the bracket box 1, so that the closed protective door 5 and the bracket box 1 form a complete protective box, which can shield and protect the photovoltaic panel body 4 in the face of harsh environment.

[0036] Specifically, in this technical solution, the photovoltaic panel body 4 is rinsed and cleaned using a water spray frame 25, according to... Figure 8 , Figure 9 , Figure 12 and Figure 13 As shown, after the photovoltaic panel body 4 enters the cavity of the bracket box 1, the protective door 5 flips and closes on the bracket box 1. Since a water spray frame 25 is fixedly connected to the inner plate surface of the protective door 5, and the water spray frame 25 is connected to a water supply device (the water supply device is existing technology and is not described in detail in the attached drawings of the specification) through a spring hose, and since there are spray nozzles evenly spaced on the water spray frame 25, the arrangement position of the spray nozzles corresponds to the entire surface of the photovoltaic panel body 4, and the entire surface of the photovoltaic panel body 4 is rinsed and cleaned by the water spray frame 25. Because a water collection trough 102 is provided inside the cavity of the bracket box 1, and the water collection trough 102 is arranged in a square ring structure according to the cavity of the bracket box 1, and because the area of ​​the photovoltaic panel body 4 is smaller than the area of ​​the cavity in the bracket box 1, that is, there are gaps between the front, back, left and right four sides of the photovoltaic panel body 4 and the front, back, left and right four sides of the cavity wall of the bracket box 1, and because the front, back, left and right four sides of the photovoltaic panel body 4 correspond to the front, back, left and right four sides of the water collection trough 102, the cleaning wastewater on the photovoltaic panel body 4 slides into the water collection trough 102 through the gaps between the sides of the photovoltaic panel body 4 and the cavity wall of the bracket box 1. Since the lower side wall of the water collection tank 102 is provided with drainage holes at equal intervals, and the lower side wall of the water collection tank 102 is inclined towards the drainage holes, the water collection tank 102 can completely catch the cleaning wastewater sliding off the photovoltaic panel body 4, and discharge the cleaning wastewater through the drainage holes in the water collection tank 102.
