Description

Technical Field

[0001] This invention relates to the field of solar photovoltaic technology, specifically to a solar photovoltaic module concentrator. Background Technology

[0002] Solar photovoltaic (PV) module concentrators are widely used in solar streetlights, distributed photovoltaic power generation systems, and other fields. They improve the light energy reception efficiency per unit area of ​​solar PV panels through concentrators, thereby enhancing power generation or energy storage performance. This is to adapt to changes in the angle of solar incidence at different times and seasons. Existing devices typically include angle adjustment mechanisms to optimize light collection. However, current solar photovoltaic (PV) module concentrators usually only focus on daytime concentration and angle adjustment, neglecting to consider that at night or under insufficient light conditions, other ambient light sources (such as streetlights, porch lights, and advertising light boxes) can continuously illuminate the solar PV panels. This can cause the PV system to misinterpret the situation as still being in daytime mode, resulting in delayed or delayed lighting of controlled lighting equipment (such as solar streetlights), affecting normal operation and user experience. Furthermore, solar PV panels exposed to the outdoor environment for extended periods are prone to dust accumulation, further reducing photoelectric conversion efficiency, and existing devices lack effective nighttime shading and dustproof structures.

[0003] Therefore, a solar photovoltaic module concentrator is proposed to address the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a solar photovoltaic module concentrator.

[0005] The objective of this invention is achieved through the following technical solution: a solar photovoltaic module concentrating device, comprising a solar photovoltaic panel and a concentrator located in front of the solar photovoltaic panel, and further comprising a base and a connecting plate fixed to the solar photovoltaic panel, wherein a sliding seat plate is slidably fitted on the base, and a rotating component is provided between the sliding seat plate and the connecting plate, the rotating component causing the connecting plate to rotate to adjust the tilt angle of the solar photovoltaic panel; A shading plate is located in the gap between two adjacent solar photovoltaic panels. A drive slide plate is movable on the connecting plate, and a connecting rod is rotatably connected to the drive slide plate. A rotating disk is rotatably connected to the connecting plate through a fixed plate. The end of the connecting rod is rotatably connected to the edge of the rotating disk. A swing plate that is rotatably connected to the shading plate is movable through the rotating disk. The angle adjustment function improves the daytime light concentration efficiency. The linkage mechanism realizes the automatic extension and covering of the shading plate, which blocks the solar photovoltaic panels at night or when light is not needed, avoiding misjudgment caused by interference from the surrounding light source, while preventing dust accumulation and improving system reliability.

[0006] As a further description of the above technical solution: A connecting plate is fixedly connected between the two connecting plates, located on both sides of the light-shielding plate; this enhances the connection stability between the two connecting plates, ensures that the light-shielding plate is subjected to uniform force on both sides during movement, avoids skewing or jamming, and improves the smoothness of the mechanism's operation.

[0007] As a further description of the above technical solution: The bottom end of the swing plate is rotatably connected to a hinge plate, on which two rollers are rotatably connected and roll in cooperation with each other. The rollers are fixedly connected to the light-shielding plate. The rolling cooperation of the rollers reduces friction and makes the light-shielding plate rotate more smoothly. At the same time, it increases the degree of freedom of connection between the light-shielding plate and the swing plate, adapts to the posture changes of the light-shielding plate during the extension process, and avoids jamming.

[0008] As a further description of the above technical solution: A second electric push rod is fixedly connected to the connecting plate. The telescopic end of the second electric push rod is connected and fixed to the drive slide plate. Two limiting plates that press against the connecting rod are fixedly connected to the drive slide plate. The second electric push rod provides a stable and controllable driving force, and the limiting plates ensure that the connecting rod moves along a predetermined trajectory, thereby realizing the precise extension and retraction of the light shield and improving the accuracy and repeatability of the control.

[0009] As a further description of the above technical solution: One end of the fixed plate is fixedly connected to the connecting plate, and the other end is fixedly connected to a limiting ring that is connected to the rotation of the rotating disk to ensure transmission accuracy.

[0010] As a further description of the above technical solution: The solar photovoltaic panel is fixedly connected to a limiting rod that cooperates with the shading plate at its end, and a limiting post that cooperates with the shading plate is fixedly connected to the edge of the solar photovoltaic panel. The limiting rod and the limiting post restrict the excessive movement of the shading plate, prevent the shading plate from directly hitting the surface of the solar photovoltaic panel, avoid scratching or damaging the solar photovoltaic panel, and ensure that a reasonable gap is maintained after the shading plate is in place.

[0011] As a further description of the above technical solution: The rotating component includes a power component and a first upright plate fixedly connected to the base. A sliding seat plate passes through the first upright plate, and a second upright plate is fixedly connected to the other end of the sliding seat plate. A first swing arm is rotatably connected to the second upright plate, and a second swing arm is rotatably connected between the connecting plate and the first swing arm. The power component causes the first swing arm to rotate. This application has a compact structure, can achieve a large range of angle adjustment, and can flexibly adjust the adjustment range by changing the distance between the first and second upright plates through the sliding seat plate, adapting to different installation environments.

[0012] As a further description of the above technical solution: The power component includes a first electric push rod that is rotatably connected to the sliding seat plate, and the telescopic end of the first electric push rod is rotatably connected to the middle of the first swing arm via a rotating shaft.

[0013] As a further description of the above technical solution: A protective sleeve that mates with the second vertical plate is fixedly connected to the rotating shaft. The end of the sliding seat plate and the base are provided with mutually matching positioning holes. A pin is inserted into the positioning holes on the base and the sliding seat plate.

[0014] As a further description of the above technical solution: The two light-shielding plates are fixedly connected with magnetically repulsive plates; the magnetic repulsion force automatically assists the light-shielding plates to unfold and cover the position, eliminating the need for additional driving components and simplifying the structure; at the same time, it ensures that the two light-shielding plates remain in a non-contact state, avoiding collision and wear, and improving service life.

[0015] Compared with the prior art, the advantages of the present invention are as follows: This invention, by placing a movable light-shielding plate in the gap between two adjacent solar photovoltaic panels, and cooperating with a linkage transmission mechanism consisting of a drive slide, connecting rod, rotating disk, and swing plate, allows the light-shielding plate to rise and rotate to cover the surface of the solar photovoltaic panels at night or when lighting is not needed. This effectively blocks interference from other light sources in the surrounding environment, preventing misjudgments by the solar photovoltaic panels and ensuring that the lighting equipment controlled by them can start on time and accurately. Simultaneously, the light-shielding plate also prevents dust from directly accumulating on the surface of the solar photovoltaic panels, maintaining their cleanliness, which helps extend the service life of the solar photovoltaic panels and maintain high photoelectric conversion efficiency. This device has a compact structure and reliable operation, significantly improving the working stability and practicality of solar photovoltaic modules in complex lighting environments.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figures 1-11 The diagram shows an embodiment of a solar photovoltaic module concentrator provided by the present invention, including a solar photovoltaic panel 1 and a concentrator (an existing concentrator) located in front of the solar photovoltaic panel 1, as well as a base 2 and a connecting plate 3 fixed to the solar photovoltaic panel 1. A sliding seat plate 4 is slidably fitted on the base 2, and a rotating component is provided between the sliding seat plate 4 and the connecting plate 3. The rotating component causes the connecting plate 3 to rotate and adjust the tilt angle of the solar photovoltaic panel 1. A light-shielding plate 5 is located in the gap between two adjacent solar photovoltaic panels 1. A drive slide plate 6 is movable on the connecting plate 3. A connecting rod 7 is rotatably connected to the drive slide plate 6. A rotating disk 9 is rotatably connected to the connecting plate 3 through a fixed plate 8. The end of the connecting rod 7 is rotatably connected to the edge of the rotating disk 9. A swing plate 10 movably passes through the rotating disk 9 and is rotatably connected to the light-shielding plate 5. The connecting plate 3 is driven to rotate by a rotating component, thereby changing the tilt angle of the solar photovoltaic panel 1 to track the solar altitude angle. A shading plate 5 is installed in the gap between adjacent solar photovoltaic panels 1. The driving slide plate 6 on the connecting plate 3 drives the rotating disk 9 to rotate through the connecting rod 7. The rotating disk 9 drives the swing plate 10 to move, and the swing plate 10 then drives the shading plate 5 to move, so that the shading plate 5 extends out of the gap and covers the surface of the solar photovoltaic panel 1.

[0019] Among them, the two connecting plates 3 are fixedly connected by connecting plate horizontal plates 11 located on both sides of the light-shielding plate 5; the connecting plate horizontal plates 11 are located on both sides of the light-shielding plate 5, and play a role in structural reinforcement and guidance.

[0020] A hinge plate 12 is rotatably connected to the bottom end of the swing plate 10. Two rollers 13 that roll in mutual engagement are rotatably connected to the hinge plate 12. The rollers 13 are fixedly connected to the light-shielding plate 5. When the swing plate 10 moves, the hinge plate 12 drives the rollers 13 to roll, thereby realizing the flipping action of the light-shielding plate 5.

[0021] A second electric push rod 14 is fixedly connected to the connecting plate 3. The telescopic end of the second electric push rod 14 is connected and fixedly connected to the drive slide plate 6. Two limiting plates 15 are fixedly connected to the drive slide plate 6 and are in contact with the connecting rod 7. When the second electric push rod 14 extends or retracts, it pushes the drive slide plate 6 to move. The limiting plates 15 restrict the range of motion of the connecting rod 7, so that the end of the connecting rod 7 makes a circular motion, which drives the rotating disk 9 to rotate.

[0022] One end of the fixed plate 8 is fixedly connected to the connecting plate 3, and the other end is fixedly connected to a limiting ring 16 that is rotatably connected to the rotating disk 9. The rotating disk 9 is rotatably connected to the limiting ring 16, and the limiting ring 16 plays a positioning role for the rotating disk 9 to prevent the rotating disk 9 from moving or swaying during rotation.

[0023] During the movement of the light-shielding plate 5, it will come into contact with the limiting rod 17 and the limiting post 18. That is, the end of the solar photovoltaic panel 1 is fixedly connected to the limiting rod 17, which cooperates with the light-shielding plate 5. When the light-shielding plate 5 moves within the gap, it contacts the limiting rod 17 and slides along the limiting rod 17 without contacting the solar photovoltaic panel 1 and causing damage to the solar photovoltaic panel 1. The edge of the solar photovoltaic panel 1 is fixedly connected to the limiting post 18, which cooperates with the light-shielding plate 5. When the light-shielding plate 5 rotates and covers the solar photovoltaic panel 1, it contacts the limiting rod 17 and the limiting post 18, but does not directly contact the solar photovoltaic panel 1.

[0024] The rotating component includes a power component and a first upright plate 19 fixedly connected to the base 2. A sliding seat plate 4 passes through the first upright plate 19. A second upright plate 20 is fixedly connected to the other end of the sliding seat plate 4. A first swing arm 21 is rotatably connected to the second upright plate 20. A second swing arm 22 is rotatably connected between the connecting plate 3 and the first swing arm 21. The power component causes the first swing arm 21 to rotate. The power component drives the first swing arm 21 to rotate, which in turn drives the connecting plate 3 to tilt through the second swing arm 22, thereby achieving angle adjustment.

[0025] The power component includes a first electric push rod 23 that is rotatably connected to the sliding seat plate 4. The telescopic end of the first electric push rod 23 is rotatably connected to the middle of the first swing arm 21 through a rotating shaft 24. When the first electric push rod 23 extends or retracts, a torque is generated because the rotating shaft 24 is off-center from the rotation center of the first swing arm 21, causing the first swing arm 21 to rotate around the second vertical plate 20.

[0026] The rotating shaft 24 is fixedly connected to a protective sleeve 25 that cooperates with the second vertical plate 20. The end of the sliding seat plate 4 and the base 2 are provided with mutually cooperating positioning holes 26. The positioning holes 26 on the base 2 and the sliding seat plate 4 are inserted by a pin. The protective sleeve 25 restricts the rotation range of the first swing arm 21 to avoid overtravel damage to the mechanism.

[0027] It is worth noting that a magnetic suction plate with magnetic repulsion is fixedly connected to the light-shielding plate 5; when the light-shielding plate 5 extends out of the gap and approaches, the repulsive force pushes the light-shielding plate 5 to separate to both sides, so that it is tightly attached to the edge of the solar photovoltaic panel 1 or the limiting post 18.

[0028] Working principle: Adjusting the angle of the solar photovoltaic panel 1: By controlling the extension and retraction of the telescopic end of the tilted first electric push rod 23, under the limit of the first upright plate 19, the rotating shaft 24 makes a circular motion, and the first electric push rod 23 makes an adaptive rotation, realizing the circular motion of the first swing arm 21. The first swing arm 21 does not need to rotate many times, and the rotation does not exceed 150 degrees. The protective sleeve 25 on the rotating shaft 24 does not need to rotate after contacting the second upright plate 20. Due to the change of the angle of direct sunlight (sunrise-sunset), excessive rotation is not required. The first swing arm 21 makes a circular motion at a certain angle, while the first upright plate 19 remains stationary, driving the second swing arm 22 and the connecting plate 3 to rotate adaptively, thereby causing the angle of the solar photovoltaic panel 1 to change.

[0029] Change the adjustment range of solar photovoltaic panel 1: By moving the sliding seat plate 4, the position of the first electric push rod 23 and the second upright plate 20 is moved, so that the distance between the first upright plate 19 and the second upright plate 20 changes, while the rotation angle of the first swing arm 21 remains unchanged (not exceeding 150 degrees), thereby changing the rotation range of the connecting plate 3 (solar photovoltaic panel 1).

[0030] Raise and rotate the shade plate 5 to block the solar photovoltaic panel 1: When night falls, to prevent other light sources (such as streetlights and porch lights that are on all night) from interfering with the solar photovoltaic panel 1 and causing it to misinterpret "it's not dark yet," thus turning off or delaying its activation, the shade plate 5 needs to be used to block the light and prevent dust accumulation. The specific operation is as follows: The first electric push rod 23 remains stationary, while the second electric push rod 14 is activated. The telescopic end of the second electric push rod 14 extends, driving the slide plate 6 to move, which in turn moves the connecting rod 7. Under the action of the limiting plate 15, the end of the connecting rod 7 makes a circular motion, and the rotating disk 9 rotates counterclockwise, thereby causing the swing plate 10 to rotate counterclockwise. This causes the hinge plate 12 and the light-shielding plate 5 to move along the gap between the two solar photovoltaic panels 1, and the swing plate 10 moves along the rotating disk 9; causing the light-shielding plate 5 to extend out of the gap, and the hinge plate 12 to be located in the gap. When the light shield 5 is separated from the limiting plate 15, the two light shields 5 rotate and come into contact with the pressure column under the action of mutual repulsion and magnetic attraction, thereby completing the protection.
