Description

Technical Field

[0001] The present invention relates to the technical field of clean energy power generation, and particularly to a clean energy power generation device. Background Art

[0002] With the intensification of climate change and the depletion of fossil energy, the global energy structure is accelerating towards clean and low-carbon transformation. Clean energy (such as solar energy, wind energy, water energy, geothermal energy, etc.) has become the key to achieving the carbon reduction goal due to its characteristics of zero carbon emissions and renewable resources. According to the statistics of the International Energy Agency (IEA), the proportion of global clean energy power generation exceeded 40% in 2023, among which the contribution rate of solar energy reached 15%, ranking first in terms of growth rate.

[0003] As the core direction of renewable energy, the energy capture efficiency of solar power generation directly determines the economy and practicability of the power generation system. With the progress of photovoltaic technology, the photoelectric conversion efficiency of solar cells has increased from less than 10% in the early stage to 22 - 24% of current commercial monocrystalline silicon cells, but the energy capture efficiency at the system level is still restricted by factors such as the change of the sun's position, environmental occlusion, and surface pollution.

[0004] The efficiency of solar power generation is limited by three major bottlenecks: static support design, tracking system defects, and surface pollution. Static support efficiency loss: Traditional fixed supports are calibrated for inclination based on latitude once and cannot adapt to the dynamic changes of the sun's azimuth and altitude angles, resulting in significant cosine losses. For example, a deviation between the fixed inclination and the sun's angle can reduce the energy reception rate to 86.6% of the theoretical value, and the loss is exacerbated at low sun altitude angles in winter, with an average annual power generation reduction of 20 - 30%. Defects in dynamic tracking systems: Although single-axis / double-axis tracking systems can increase energy capture by 30 - 40%, they have high mechanical complexity. The double-axis system requires multiple sets of motors and support structures, resulting in a large volume and complex installation. Surface pollution efficiency attenuation: Dust and snow accumulation cause optical occlusion and hot spot effects, and the monthly average efficiency loss in arid areas exceeds 10%. The limitations of existing cleaning technologies are obvious: rainwater flushing depends on weather conditions; robots require additional rail power supply; the water consumption of the water spraying system is large (1 - 2 L / m²), it is easy to freeze at low temperatures, traditional cleaning requires shutdown operations, further reducing production capacity, and the cost of manual cleaning is high. Therefore, it is necessary to design a clean energy power generation device with strong practicability and efficient energy capture. Summary of the Invention

Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figure 1-10, the present invention provides a technical solution: a clean energy power generation device, including a mounting base 1 and a solar panel 2. The upper end of the mounting base 1 is respectively provided with a central support member 3 and an edge support member 4. The solar panel 2 is supported and fixed by the central support member 3 and the edge support member 4 together. The edge support member 4 can be adjusted in height. The upper end of the mounting base 1 is provided with a circumferential guide member 5. The circumferential guide member 5 includes a guide ring 51, a guide block 52 and a ring gear 53. The guide ring 51 is fixedly installed at the upper end of the mounting base 1. The guide block 52 is movably installed on the guide block 52. The outer arc surface of the guide ring 51 is inlaid with the ring gear 53. The edge support member 4 is arranged on the guide block 52 to facilitate the circumferential adjustment of the solar panel 2. One side of the guide block 52 is provided with a circumferential driving member 6 and the other side is provided with a hydraulic transmission member 7. The solar panel 2 is symmetrically provided with cleaning plates 8. The solar panel 2 is symmetrically provided with linear guide members 9. The cleaning plates 8 are linearly guided by the linear guide members 9 and driven to clean by the hydraulic transmission member 7;

[0039] The mounting base 1 serves as the basic supporting structure of the entire device. The mounting base 1 is fixed on the ground to provide a stable foundation for other components. The central support 3 is installed at the upper end of the mounting base 1 to support the central part of the solar panel 2 to ensure the stability and balance of the solar panel 1. The edge support 4 is also installed at the upper end of the mounting base 1, located at the edge of the solar panel 2, and can be raised and lowered. The lifting function of the edge support 4 allows the angle of the solar panel 2 to be adjusted to optimize the angle at which it receives sunlight. The circumferential guide 5 includes a guide ring 51, a guide block 52 and an annular rack 53. The guide ring 51 is fixed on the mounting base 1, and the guide block 52 is movably installed on the guide ring 51 and can rotate freely on the guide ring 51. The annular rack 53 is embedded in the outer arc surface of the guide ring 51 to provide a meshing surface for the circumferential drive member 6. The circumferential drive member 6 is installed on one side of the guide block 52 and meshes with the annular rack 53. By driving the guide block 52 to rotate around the guide ring 51, the solar panel 2 is driven to adjust in the circumferential direction. At the same time, through the external independently set solar tracking sensor The solar tracking sensor is a common technical means in the technical field, which will not be described in detail here. The hydraulic transmission member 7 is installed on the other side of the guide block 52 to drive the cleaning plate 8 to move linearly. The hydraulic transmission member 7 provides power through the hydraulic system to ensure that the cleaning plate 8 can slide smoothly on the surface of the solar panel 2. The cleaning plate 8 is symmetrically installed on both sides of the solar panel 2 and guided by the linear guide 9 to ensure that the cleaning plate 8 remains straight during movement to avoid deviation. The surface of the cleaning plate 8 is equipped with a wiping material to remove dust and dirt on the surface of the solar panel to ensure its efficient energy absorption capacity. The linear guide 9 is installed on both sides of the solar panel 2 to provide a linear motion track for the cleaning plate 8 to ensure that the cleaning plate will not deviate from the track during the cleaning process, improve the cleaning efficiency and effect, and ensure that the solar panel can remain clean even under severe weather conditions, reducing energy loss caused by dust accumulation. The automated operation of the cleaning plate 8 greatly reduces maintenance costs and improves the overall reliability of the system.

[0040] Specifically, the central support member 3 includes a central support block 31, a central movable column 32 and a hinge head 33. The central support block 31 is fixedly mounted at the center position of the upper end of the mounting seat 1. The central movable column 32 is movably mounted on the central support block 31. The upper end of the central movable column 32 is movably mounted on the lower end of the solar panel 2 through the hinge head 33.

[0041] The central support block 31 is fixed at the center of the upper end of the mounting base 1, and serves as the core fulcrum of the entire support system to ensure that the force of the solar panel 2 is evenly distributed. When the central movable column 32 is adjusted in the circumferential direction (such as tracking the solar azimuth), the central movable column 32 serves as a rotation fulcrum to maintain the stability of the solar panel 2;

[0042] Specifically, the edge support member 4 includes a telescopic cylinder 41, a connecting block 42, and a second hinge joint 43. The telescopic cylinder 41 is fixedly installed at the upper end of the guide block 52, the connecting block 42 is fixedly installed at the lower end of the solar panel 2, and the connecting block 42 and the telescopic end of the telescopic cylinder 41 are movably connected through the second hinge joint 43;

[0043] When the telescopic cylinders 41 of multiple edge support members 4 expand and contract synchronously, the solar panel 2 takes the first hinge joint 33 of the central support member 3 as a fulcrum to form a single-axis tilt (such as north-south adjustment). When the guide block 52 rotates along the guide ring 51, the telescopic cylinder 41 fixed thereon drives the solar panel 2 to rotate around the central support member 3 synchronously, realizing the horizontal azimuth angle adjustment (such as tracking the rising and setting of the sun). The combination of the telescopic cylinder 41 and the second hinge joint 43 enables the solar panel 2 to have multi-dimensional adjustment capabilities of tilt angle and azimuth angle, significantly improving the light energy capture efficiency. In practical applications, the number of edge support members 4 is allowed to be flexibly adjusted according to the installation environment (such as terrain, climate, load requirements, etc.), improving the adaptability and practicability of the device. Each guide block 52 corresponds to one edge support member 4. For example, in urban rooftop photovoltaics, a single edge support member 4 can be set to minimize costs. In mountain slope installations, double edge support members 4 can be set to form a triangular stable structure. In high-wind pressure areas, multiple edge support members 4 can be set, with multi-point support enhancing the anti-sandstorm ability, reducing the single-point load, and extending the structural life. Users can choose the minimum necessary number (1) according to the initial budget and expand it later as needed. When making multi-point settings, each telescopic cylinder 41 is equipped with an independent controller, which communicates with the main control unit through a bus protocol (CAN or RS485) to achieve the coordinated adjustment of multiple edge support members 4;

[0044] Specifically, an arc-shaped groove 521 is formed at the lower end of the guide block 52, the guide ring 51 is located within the arc-shaped groove 521, an arc-shaped limit block 522 is fixedly installed on the inner arc surface of the arc-shaped groove 521, a ring-shaped groove 511 is formed on the inner arc surface of the guide ring 51, and the arc-shaped limit block 522 is movably installed within the arc-shaped groove 521;

[0045] The lower end of the guide block 52 is designed with an arc-shaped groove 521, and the shape of the arc-shaped groove 521 matches the outer arc surface of the guide ring 51, ensuring that the guide block 52 can rotate smoothly along the guide ring 51. On the inner arc surface of the arc-shaped groove 521, an arc-shaped limit block 522 is fixedly installed, and the function of this limit block is to prevent it from exceeding the predetermined range during the rotation process;

[0046] Specifically, the circumferential driving member 6 includes a first fixing plate 61, a servo motor 62, and a first gear 63. The first fixing plate 61 is fixedly installed on one side of the guiding block 52. The servo motor 62 is fixedly installed at the lower end of the first fixing plate 61, and the output end thereof is fixedly installed with the first gear 63. An avoidance groove 523 is formed on the outer arc surface of the arc-shaped groove 521. The annular rack 53 is located in the avoidance groove 523, and the first gear 63 is meshed and connected with the annular rack 53;

[0047] The first fixing plate 61 is fixed on one side of the guiding block 52 to serve as a bearing platform for the servo motor 62. The servo motor 62 is fixed at the lower end of the first fixing plate 61, and the output shaft is connected to the first gear 63. The avoidance groove 523 is formed on the outer arc surface of the arc-shaped groove 521 of the guiding block 52 to provide a meshing space for the annular rack 53 and the first gear 63 and avoid structural interference;

[0048] Specifically, the cleaning plate 8 is integrally arranged in a C shape. Inner gripping handles 81 are provided at both ends of the cleaning plate 8. The inner gripping handles 81 are movably clamped and installed on the side wall of the solar panel 2. A cleaning cloth 82 is embedded in the inner wall of the cleaning plate 8 for cleaning the outer wall surface of the solar panel 2;

[0049] The cleaning plate 8 is integrally in a C shape with the opening facing the side of the solar panel 2, forming a semi-surrounding structure that adapts to the surface profiles of single or multiple side-by-side solar panels. The inner gripping handles 81 and the main body of the cleaning plate 8 are connected by a buckle, enabling quick disassembly. At the same time, it is convenient to replace the internal cleaning cloth 82. The cleaning cloth 82 is fixed by Velcro or an embedded chute, supporting quick replacement;

[0050] Specifically, the linear guiding members 9 and the cleaning plates 8 are arranged in one-to-one correspondence. The linear guiding member 9 includes a first positioning block 91, a second positioning block 92, and a linear push-pull member 93. The first positioning block 91 is fixedly installed on the side wall of the solar panel 2. The second positioning block 92 is fixedly installed on the cleaning plate 8. The second positioning block 92 is located between the first positioning blocks 91. The linear push-pull member 93 is arranged between the first positioning block 91 and the second positioning block 92 that are at a relatively far distance from each other, and the linear push-pull member 93 is arranged in a staggered manner;

[0051] The first positioning block 91 is fixedly installed on the side walls on both sides of the solar panel 2. As the fixed end points of the linear guide 9, the second positioning block 92 is installed on the cleaning plate 8 and is located between the two first positioning blocks 91 for connecting the linear push-pull member 93. The linear push-pull member 93 connects the first positioning block 91 and the second positioning block 92, providing the power and guidance for the cleaning plate 8 to move linearly. The linear push-pull member 93 is driven by a hydraulic system to push or pull the cleaning plate 8 to move linearly. Through the connection of the linear push-pull member 93 between the first positioning block 91 and the second positioning block 92, it is ensured that the cleaning plate 8 moves along a predetermined linear path, avoiding deviation. The linear push-pull member 93 is misaligned between the first positioning block 91 and the second positioning block 92 and needs to adapt to the length of the solar panel 2 or the moving range of the cleaning plate 8, which can ensure that the stroke of the linear push-pull member 93 is long enough;

[0052] Specifically, the linear push-pull member 93 includes a linear guide cylinder 931, a linear guide rod 932, and a first piston plate 933. One end of the linear guide cylinder 931 is fixed to the side wall of the first positioning block 91 and the other end penetrates through the adjacent second positioning block 92. The first piston plate 933 is movably installed in the linear guide rod 932. One end of the first piston plate 933 adjacent to the second positioning block 92 is fixedly installed with the linear guide rod 932. The linear guide rod 932 penetrates through the linear guide cylinder 931 and is fixedly installed on the side wall of the corresponding second positioning block 92;

[0053] The linear push-pull member 93 is controlled by a hydraulic drive system. The first piston plate 933 moves within the guide rod 932 through the push and pull action of the hydraulic pressure. When the drive system applies a thrust, the first piston plate 933 moves along the guide rod 932, driving the cleaning plate 8 to move from one end of the solar panel 2 to the other end. After the cleaning is completed, the drive system applies a reverse force to return the first piston plate 933 to its initial position, completing a cleaning cycle;

[0054] Specifically, the hydraulic transmission member 7 includes a second fixing plate 71, a hydraulic cylinder 72, a delivery pipe 73, a third fixing plate 74, a flow distribution valve 75, a shunt pipe 76, and a connector 77. The second fixing plate 71 is fixed on the other side of the guide block 52. The hydraulic cylinder 72 is arranged within the second fixing plate 71. The third fixing plate 74 is fixedly installed on the side wall of the telescopic cylinder 41. The flow distribution valve 75 is fixedly installed on the third fixing plate 74. The upper end of the hydraulic cylinder 72 is provided with the delivery pipe 73 and the end of the delivery pipe 73 is connected to the flow distribution valve 75. One end of the linear guide cylinder 931 away from the linear guide rod 932 is provided with the connector 77. The connector 77 and the flow distribution valve 75 are connected and communicated through the shunt pipe 76;

[0055] The piston of the hydraulic cylinder 72 compresses the hydraulic oil under the drive of external power to generate a high-pressure oil flow. The high-pressure oil enters the flow distribution valve 75 through the delivery pipe 73. The flow distribution valve 75 distributes the oil proportionally to each shunt pipe 76 according to the control signal (manual or electric control). The cleaning plate 8 in this application moves at a constant speed and the valve opening is constant. The shunt pipe 76 delivers the hydraulic oil to the connector 77 and enters the linear guide cylinder 931, pushing the piston plate one 933 to move along the linear guide rod 932, thereby driving the cleaning plate 8 to complete a linear cleaning stroke;

[0056] Specifically, the hydraulic cylinder 72 includes a hollow transmission cylinder 721, a second gear 722, a transmission shaft 723, a second piston plate 724, a fixed rod 725 and a reciprocating push plate 726. The hollow transmission cylinder 721 is fixedly installed in the first fixing plate 61 and the lower end of the hollow transmission cylinder 721 is movably installed with the transmission shaft 723. The lower end of the transmission shaft 723 is fixedly installed with the second gear 722. The second gear 722 is meshed and connected with the annular rack 53. The upper end of the transmission shaft 723 extends into the hollow transmission cylinder 721. The upper end of the transmission shaft 723 is provided with a reciprocating thread and is threadedly connected with the reciprocating push plate 726. The second piston plate 724 is movably installed in the hollow transmission cylinder 721. The second piston plate 724 is located above the reciprocating push plate 726. The second piston plate 724 and the reciprocating push plate 726 are fixedly connected through the fixed rod 725. The fixed rods 725 are arranged in a circumferential array;

[0057] When the servo motor 62 drives the first gear 63 to rotate along the annular rack 53, the second gear 722 synchronously meshes with the rack 53, forcing the transmission shaft 723 to rotate around its own axis. The rotation of the transmission shaft 723 drives the reciprocating push plate 726 to move up and down through the reciprocating thread. The reciprocating push plate 726 drives the second piston plate 724 to move up and down through the fixed rod 725. When the second piston plate 724 moves up, the hydraulic oil is discharged from the hollow transmission cylinder 721 through the delivery pipe 73, pushing the cleaning plate 8 to move. When the second piston plate 724 moves down, the hydraulic oil is replenished from the delivery pipe 73 into the hollow transmission cylinder 721 to prepare for the next cycle. Integrating gear transmission, thread conversion and hydraulic compression into a single hollow transmission cylinder 721 greatly reduces the space occupied and is suitable for narrow installation environments. The reciprocating thread design allows the second piston plate 724 to output effective thrust during both forward and reverse rotations, enabling the reciprocating movement of the cleaning plate 8 without an additional reversing valve, simplifying the system.

[0058] Working principle: This device takes the solar panel 8 as the core and combines an adaptive support structure, a solar tracking system and an automatic cleaning module to achieve efficient light energy capture and operation and maintenance. Its design is centered around the following core objectives:

[0059] 1. Dynamic angle adjustment: Through the coordination of the central support 3 and the edge support 4, the pitch angle (tilt angle) and azimuth angle (horizontal rotation) of the solar panel 2 can be adjusted in two degrees of freedom to maximize the sunlight incident angle.

[0060] 2. Closed-loop tracking control: By utilizing the linkage between the circular drive member 6 and the hydraulic transmission member 7, the solar panel 2 can track the sun's trajectory in real time, greatly improving the efficiency of light energy conversion.

[0061] 3. Self-cleaning mechanism: The cleaning panel 8 covers the panel surface through hydraulically driven linear motion, and with the C-shaped wrapping design, it removes pollutants such as dust and snow to maintain photovoltaic efficiency.

[0062] 4. Power sharing architecture: The servo motor 62 drives the annular rack 63 to synchronously complete the plate surface azimuth adjustment and hydraulic cleaning power generation, eliminating independent drive energy consumption.

[0063] The workflow is as follows:

[0064] 1. Sun position tracking and angle adjustment

[0065] Start-up stage: the servo motor 62 drives the gear 1 63 to mesh with the annular rack 53, driving the guide block 52 to rotate along the guide ring 51, so as to adjust the horizontal azimuth angle of the solar panel 2 (tracking the rising and setting of the sun).

[0066] Tilt angle adjustment: The telescopic cylinders 41 of the multiple edge supports 4 are synchronously extended and retracted, and the central support 3 is used as a fulcrum to adjust the pitch angle of the solar panel 2 to adapt to the seasonal changes in the solar altitude angle.

[0067] 2. Cleaning system startup mechanism

[0068] Trigger signal: When the servo motor 62 of the circumferential drive member 6 is started and drives the solar panel 2 to adjust the circumferential direction, the cleaning system starts to start.

[0069] Mechanical linkage: The power of the servo motor 62 is transmitted to the guide block 52 through the meshing of gear 1 63 and the annular rack 53, and at the same time, the power is transmitted to the hydraulic transmission part 7 through the transmission shaft 723 and gear 2 722.

[0070] Power transmission; through the servo motor 62, gear 1 63 and the ring rack 53, it is transmitted to the gear 2 722, and the transmission ratio can be adjusted and set according to needs.

[0071] 3. Cleaning plate linear motion execution

[0072] Hydraulic distribution: High-pressure oil is distributed to each branch pipe 76 as needed through the flow distribution valve 75, driving the piston plate 933 of the linear push-pull member 93 to move.

[0073] Speed control: The opening of the valve regulates the oil flow rate, and the moving speed of the cleaning plate 8 is set as required (low speed in dust mode to prevent dust from rising, high speed in snow accumulation mode to break ice).

[0074] Guiding and covering: The cleaning plate 8 slides along the linear guide 9, and the C-shaped structure wraps the edge of the solar panel 8. The cleaning cloth 82 contacts the surface of the solar panel 8 with appropriate pressure, and the covering width in a single stroke is ≥95%.

[0075] Reciprocating cleaning: The hydraulic cylinder 72 controls the oil flow direction to achieve the automatic back-and-forth movement of the cleaning plate 8.
