Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel regulation, and more particularly to a multi-link regulation device for photovoltaic panels based on outdoor camping vehicles. Background Technology

[0002] The photovoltaic power generation system of outdoor camping RVs relies on solar panels to efficiently collect sunlight. However, the solar altitude angle and azimuth angle change dynamically with geographical location, season, and time. If the photovoltaic panel maintains a fixed tilt angle, its light-receiving surface cannot always be perpendicular to the sunlight, resulting in a decrease in irradiance per unit area. This is especially true in dawn and dusk or in high-latitude regions, where the power generation efficiency is significantly reduced. By adjusting the tilt angle of the photovoltaic panel in real time to track changes in the solar altitude angle, the light energy conversion efficiency can be maximized, extending the RV's off-grid range. This is the core requirement for angle adjustment.

[0003] Traditional photovoltaic (PV) panel adjustment mechanisms often employ a single-axis rotation design, where one end is fixed as a pivot shaft, and the bottom is driven by a linkage structure to adjust the PV panel's pitch around the axis. However, this design has certain limitations: First, the pitch angle adjustment direction is fixed. When the pivot shaft is close to the direction of solar incidence, the PV panel needs to adjust its tilt angle in the opposite direction to be perpendicular to the sunlight. At this time, a horizontal rotation mechanism needs to be activated simultaneously to adjust the overall orientation, which not only increases the driving energy consumption but also reduces the efficiency of PV panel alignment. Second, when multiple PV panels on the roof of a motorhome are adjusted independently, adjacent panels are prone to forming shadows due to tilt angle deviations, resulting in a sharp decrease in power generation in local areas. Existing systems lack real-time collaborative algorithms based on shading feedback, making it difficult to dynamically balance angle deviations and overall energy efficiency.

[0004] Therefore, it is necessary to propose a multi-link adjustment device for photovoltaic panels based on outdoor camping RVs to solve the above problems. Summary of the Invention

[0040] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0041] According to one embodiment of the present invention, Figures 1-15 As shown.

[0042] like Figures 1-9As shown, a multi-link adjustment device for photovoltaic panels based on an outdoor camping RV includes a base frame 1 and three photovoltaic panels 2 mounted on the upper part of the base frame 1. A horizontal rotary motor 5 is installed at the bottom of the base frame 1 to drive its horizontal rotation. The horizontal rotary motor 5 is mounted on the roof of the camping RV. A multi-link adjustment mechanism is provided between each photovoltaic panel 2 and the base frame 1. The multi-link adjustment mechanism includes rotating shafts 15 located at both ends of the bottom of the photovoltaic panel 2. Support frames 12 corresponding to the rotating shafts 15 are provided on both sides of the base frame 1. The upper end of each support frame 12 has a groove 20 adapted to the rotating shaft 15. Connecting shafts 11 are symmetrically arranged at both ends below the photovoltaic panel 2. A pair of first connecting rods 10 are rotatably connected to each end of each connecting shaft 11. One end of each pair of first connecting rods 10, away from the connecting shaft 11, is rotatably connected to the bottom center of the photovoltaic panel 2, and the other end of the first connecting rod 10, away from the connecting shaft 11, is rotatably connected to the upper center of the photovoltaic panel 2. The photovoltaic panel 2 is symmetrically and movably connected to both ends of a traction frame 16. Specifically, the photovoltaic panel 2 is provided with linear guide rails corresponding to the traction frame 16 at both ends. The traction frame 16 is movably connected to the linear guide rails to ensure stability. A telescopic rod is rotatably provided at the upper end of the traction frame 16. The other end of the telescopic rod is rotatably connected to the connecting shaft 11. The telescopic rod includes a first inner rod 29 rotatably provided on the connecting shaft 11 and a second connecting rod 13 rotatably provided at the upper end of the traction frame 16. The second connecting rod 13 is a hollow structure, and one end of the second connecting rod 13 is movably sleeved outside one end of the first inner rod 29. The photovoltaic panel 2 is rotatably provided with a lead screw 9 at both ends. The lead screw 9 is threaded with a movable frame 8 that is movably engaged with the upper end of the base frame 1 and is used to push the traction frame 16 to move. Specifically, the photovoltaic panel 2 is provided with linear guide rails corresponding to the movable frame 8 at both ends. The movable frame 8 is movably connected to the linear guide rails. An angle adjustment motor 7 for driving the lead screw 9 to rotate is provided on the side of the base frame 1.

[0043] like Figures 7-9 , Figure 13As shown, in order to restrict the rotation shaft 15 at one end, a second limiting plate 17 is movably installed through the upper end of the fulcrum 12. The second limiting plate 17 is L-shaped. The end of the movable frame 8 is provided with a traction rod 18 corresponding to the second limiting plate 17 and used to pull the displacement of the second limiting plate 17. The traction rod 18 is a hollow structure and is installed through the fulcrum 12. A second inner rod 37 is provided on the side wall of one end of the second limiting plate 17 and is movably connected to the inside of the traction rod 18. A third elastic element is provided on the outside of the second inner rod 37. The third elastic element 38 is preferably a spring. The second inner rod 37 is T-shaped, and the spring is sleeved on the outside of the second inner rod 37. When the second inner rod 37 and the traction rod 18 move away from each other, the third elastic element 38 can be compressed. The side of the traction frame 16 is provided with a straight groove 23. The side wall of the moving frame 8 is provided with a T-shaped traction rod 22 extending to the inside of the straight groove 23. The T-shaped traction rod 22 is movably connected to the traction frame 16. The traction frame 16 will only be pushed to move when one end of the T-shaped traction rod 22 reaches the end of the straight groove 23.

[0044] like Figure 9 , Figures 11-12 As shown, to prevent the telescopic rod from extending or retracting after the angle of the photovoltaic panel 2 is adjusted, a housing 28 communicating with the second connecting rod 13 is provided on the side wall of the second connecting rod 13 near the traction frame 16. A floating frame 32 is movably connected to the inner side of the housing 28 along the width direction of the second connecting rod 13. A gear tooth 30 corresponding to the housing 28 is provided on the side wall of the first inner rod 29 near the traction frame 16. A second elastic element 36 is provided on the side of the floating frame 32. Specifically, a "T"-shaped guide rod is provided on the inner wall of the housing 28. The end of the floating frame 32 is movably sleeved on the outside of the guide rod. The second elastic element 36 is preferably a spring, and the spring is sleeved on the outside of the guide rod. When the floating frame 32 moves towards the second connecting rod 13, the second elastic element 36 can be compressed. An inclined guide groove is provided on the side wall of the floating frame 32. 40. A movable arm 31 is movably connected through one end of the housing 28 near the movable frame 8. A guide wheel 34, which is movably connected to the guide groove 40, is provided at the end of the movable arm 31 near the floating frame 32. One end of the movable arm 31 protrudes from the end of the second connecting rod 13. To reduce friction, a second roller 35 is rotatably provided at the end of the movable arm 31 near the movable frame 8. An arc-shaped groove corresponding to the second roller 35 is provided on the side wall of the movable frame 8. The axis of the arc-shaped groove coincides with the axis of rotation of the second connecting rod 13 around the traction frame 16. The arc-shaped groove is used to squeeze and push the movable arm 31 to move. Since the axis of the arc-shaped groove coincides with the axis of rotation of the second connecting rod 13 around the traction frame 16, it can ensure that the second roller 35 and the arc-shaped groove always roll in cooperation when the telescopic rod changes its tilt angle, thus ensuring the stability of the floating frame 32.

[0045] like Figure 7 , Figures 9-10As shown, in order to prevent relative displacement between the T-shaped pull rod 22 and the traction frame 16 after the tilt angle of the photovoltaic panel 2 is adjusted, guide plates 19 corresponding to the traction frame 16 are provided at both ends of the base frame 1. The side of the guide plate 19 facing away from the moving frame 8 is sloping. The bottom of the traction frame 16 is provided with a notch 21 corresponding to the guide plate 19. The upper end of the inner side of the straight groove 23 is vertically and movably connected to an inverted "U"-shaped lifting frame 24, and the bottom ends of the lifting frame 24 extend to the inner side of the notch 21. The upper end of the lifting frame 24 is provided with a blocking block 27 for blocking one end of the T-shaped pull rod 22. The top of the lifting frame 24 is provided with a first elastic element 26, which is preferably a spring. The guide plate 19 is used to guide the lifting frame 24 and the blocking block 27 to rise and hide as a whole. In order to reduce friction, first rollers 25 are rotatably provided at the bottom ends of the lifting frame 24 for rolling cooperation with the top of the guide plate 19.

[0046] like Figure 1 , Figures 3-4 , Figure 14 As shown, in order to protect the upper end of the base frame 1, a protective shell 3 is provided between the photovoltaic panel 2 and the base frame 1. The upper end of the protective shell 3 is provided with a slot corresponding to the first connecting rod 10. The upper end of the first connecting rod 10 extends upward through the slot and connects with the photovoltaic panel 2.

[0047] like Figure 1 , Figures 3-4 , Figure 14 As shown, in order to restrict the first connecting rod 10 when the photovoltaic panel 2 is in a horizontal state, the first limiting plate 4 is movably connected to both ends of the top of the protective shell 3 via linear guide rails. A linear motor 39 for driving the displacement of the first limiting plate 4 is provided in the middle of the upper end of the protective shell 3. When the photovoltaic panel 2 is in a horizontal state, the linear motor 39 drives the first limiting plate 4 to restrict the upper edge of the first connecting rod 10, thereby increasing the stability of the photovoltaic panel 2.

[0048] In addition, such as Figures 5-7As shown in Figure 15, this application also includes a tilt correction system, including a tilt sensor 14 located at the bottom end of the photovoltaic panel 2. The tilt sensor 14 is used to monitor the tilt angle of the photovoltaic panel 2 in real time. A controller 6 is located on the inner side of one end of the base frame 1. The controller 6 is used to calculate the solar altitude angle, the ideal pitch angle, and the decision adjustment angle. The tilt adjustment motor 7, the horizontal rotation motor 5, the linear motor 39, and the tilt sensor 14 are all electrically connected to the controller 6. This application also includes a GPS module electrically connected to the controller 6, which is used to obtain the latitude of the geographical location. The GPS module is installed on an outdoor camping vehicle. The installation location and the specific structure of the GPS module are not shown in the figure. It is a mature prior art and will not be described in detail. This application also includes a power generation monitoring module for detecting the power generation of the photovoltaic panel 2. Specifically, it is monitored by a current / voltage sensor embedded in the output line of the photovoltaic panel 2. When there is an angular deviation between adjacent photovoltaic panels 2, it is easy to cause one of the photovoltaic panels 2 to be partially shaded, thereby affecting the power generation.

[0049] The specific principle behind the tilt correction system's angle correction adjustment is as follows:

[0050] The length of photovoltaic panel 2 is known to be The installation spacing between adjacent photovoltaic panels 2 is The system obtains the geographical location via a GPS module and calculates the solar altitude angle by combining this information with the time. and direction The actual pitch angle of the adjacent photovoltaic panel 2 is obtained through the tilt sensor 14. and Calculate the angle deviation If there is a pitch angle deviation between adjacent plates The high-angle photovoltaic panel 2 will cast a shadow on the low-angle photovoltaic panel 2 due to its tilt, and the length of the shadow projection is... Due to the height difference of the tilt of photovoltaic panel 2 and solar altitude angle Decide:

[0051] ,in ,when When shadows cover adjacent boards, corrections are needed. .

[0052] Regarding the calculation of the maximum permissible deviation angle, from Critical condition:

[0053] If measured It needs to be adjusted to .

[0054] The specific process is as follows: the power generation monitoring module detects a decrease in the power of photovoltaic panel 2 and sends a signal to controller 6. The controller reads the latitude and time from the GPS module and calculates the solar altitude angle. Simultaneously acquire tilt sensor data from both side plates. and Calculate the difference in tilt angle between adjacent plates Compare with the maximum permissible deviation ,like The controller 6 sends a PWM command to the tilt adjustment motor 7, driving the side photovoltaic panel 2 to reduce its tilt angle until... .

[0055] The tilt adjustment principle of photovoltaic panel 2 is as follows: Initially, photovoltaic panel 2 is in a horizontal state, the first roller 25 is located at the upper end of guide plate 19, the blocking block 27 is in a hidden state, and one end of the second limiting plate 17 is not obstructed from the upper end of the rotating shaft 15. The linear motor 39 is controlled to drive the first limiting plate 4 to move, and the first limiting plate 4 moves away from the upper end of the first connecting rod 10, releasing the restriction. According to the direction of the sunlight, the tilt adjustment motor 7 on the corresponding side is controlled. The tilt adjustment motor 7 drives the corresponding lead screw 9 to rotate, and the lead screw 9 drives the corresponding moving frame 8 to move. The moving frame 8 drives the second limiting plate 17 to move through the traction rod 18 and the second inner rod 37. At the same time, the moving frame 8 also drives the T-shaped traction rod 22 to move. One end of the T-shaped traction rod 22 slides in the straight groove 23. When one end of the T-shaped traction rod 22 reaches the end of the straight groove 23, the upper end of the second limiting plate 17 will move to the upper end of the rotating shaft 15 for restriction. At the same time, the inner wall of the arc-shaped groove on the side wall of the moving frame 8 will squeeze the second roller 35. The second roller 35 drives the movable arm 31 to move, and the movable arm 31 drives the guide wheel 34 to move. Under the action of the guide groove 40, the floating frame 32 moves towards the inner side of the second connecting rod 13, and the second elastic element 36 is compressed. Then, the floating frame 32 drives the locking tooth 33 to enter the inner side of the second connecting rod 13 to lock the wheel tooth 30. The first inner rod 29 will not have relative displacement with the second connecting rod 13. Subsequently, the moving frame 8 pushes the traction frame 16 to move through the T-shaped traction rod 22. During this stage, the second inner rod 37 and the traction rod 18 have relative displacement. When the elastic element 38 is compressed, the traction frame 16 pushes the connecting shaft 11 to move via the telescopic rod. The rotating shaft 15 at the other end of the photovoltaic panel 2 is not restricted by the second limiting plate 17, so the connecting shaft 11 pushes the first connecting rod 10 to change its angle, thereby realizing the adjustment of the tilt angle of the photovoltaic panel 2. Moreover, after the traction frame 16 moves away from the upper end of the guide plate 19, the first elastic element 26 returns to its original position, and then the lifting frame 24 and the blocking block 27 move down as a whole. The lower end of the blocking block 27 protrudes from the inner wall of the straight groove 23, and the blocking block 27 blocks one end of the T-shaped traction rod 22. At this time, there will be no relative displacement between the T-shaped traction rod 22 and the traction frame 16, ensuring the stability of the photovoltaic panel 2 after the angle adjustment. The first connecting rod 10 at the other end changes its angle synchronously with the tilt of the photovoltaic panel 2, and the other end... When the telescopic rod at one end is not locked, it extends, and the telescopic rod, the first connecting rod 10, and the connecting shaft 11 at one end actively lift and tilt the photovoltaic panel 2. The telescopic rod, the first connecting rod 10, and the connecting shaft 11 at the other end adapt to the change. The multi-link support limit increases the stability of the photovoltaic panel 2 and enables bidirectional tilt adjustment of the photovoltaic panel 2. Similarly, if it is necessary to tilt the photovoltaic panel 2 to the other side, simply control the tilt adjustment motor 7 on the other side. If the light is not directly facing the photovoltaic panel 2, the base frame 1 can be rotated as a whole by driving the horizontal rotary motor 5. When not in use, the photovoltaic panel 2 is in a horizontal state. Control the linear motor 39 to drive the first limiting plate 4 to move to the upper edge of the first connecting rod 10 to limit the first connecting rod 10.To prevent photovoltaic panel 2 from moving when not in use.

[0056] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
