Description
Technical Field
[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a high-efficiency photovoltaic power generation device with maximum power point tracking. Background Art
[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect at the interface of semiconductors to directly convert light energy into electrical energy. It mainly consists of three major parts: solar panels (modules), controllers, and inverters. The main components are made of electronic components. Solar cells are packaged and protected in series to form large-area solar cell modules. Combined with components such as power controllers, they form photovoltaic power generation devices. Maximum power point tracking is a technology commonly used in wind turbines and photovoltaic solar energy systems. The purpose is to obtain maximum power output under various circumstances. Maximum power point tracking is mainly used in solar power generation, but its principle can also be applied to energy sources whose input power varies, such as light energy transmission and thermophotovoltaics.
[0003] In the existing technology, since photovoltaic panels are installed on photovoltaic brackets, and the position and orientation of photovoltaic panels are usually fixed directly after installation, photovoltaic panels can only receive sunlight at specific angles. Common adjustable photovoltaic brackets are achieved through two mutually perpendicular axes to adjust the tilt forward, backward, left and right. Therefore, the adjustable photovoltaic brackets can only tilt in a specific direction, and their angles are limited. It is impossible to change the orientation of the photovoltaic panels in three-dimensional space. The rotation and revolution of the earth, the solar altitude angle and azimuth angle are constantly changing throughout the day and year. The photovoltaic brackets cannot always remain perpendicular to the sunlight, especially in the morning and evening, when the solar altitude angle is low and the angle between the incident light and the photovoltaic panel is small, resulting in a decrease in the amount of solar radiation received by the photovoltaic panel and a decrease in power generation efficiency. Summary of the Invention
[0004] In view of the deficiencies of the prior art, the present invention provides a high-efficiency photovoltaic power generation device with maximum power point tracking to solve the problems raised in the above background technology.
[0005] The above technical objectives of the present invention are achieved through the following technical solutions:
[0006] A high-efficiency photovoltaic power generation device with maximum power point tracking includes a base, a support frame is fixedly installed on the top surface of the base, a mounting frame is provided on the top surface of the support frame, and a plurality of photovoltaic panels are fixedly installed on the top surface of the mounting frame; a swing assembly is provided inside the base for swinging the mounting frame and the photovoltaic panel to change the orientation of the photovoltaic panel, and the swing assembly includes: a mounting seat, the mounting seat is fixedly installed inside the base, a plurality of fixed platforms are fixedly installed on the top surface of the mounting seat, a plurality of fixed rings are fixedly installed on the top surfaces of the fixed platforms, a spherical shell is fixedly installed between the plurality of fixed platforms, a movable column is provided inside the fixed ring, and the movable column Two active columns are fixedly installed on the outer circular wall of the column, and the two movable columns and the active column are arranged in a cross shape, which are used to achieve swing and have supporting force at the same time. A supporting column is fixedly installed on the top surface of the movable column, and a connecting block is provided inside the support column. The connecting block is fixedly installed on the bottom surface of the mounting frame for supporting the mounting frame; the outer circular wall surface of the fixed ring is provided with a position changing component for spherical swing of the mounting frame and the photovoltaic panel; the top surface of the mounting seat is provided with a driving component for driving the movable column and the active column; the top surface of the support column is provided with a lifting component for allowing the mounting frame and the photovoltaic panel to leave the surface of the support frame.
[0007] By adopting the above technical solution, through the setting of support columns, when the staff installs the photovoltaic panels, the initial positions of the mounting frame and the photovoltaic panels are in an inclined state, and then by using the driving component, the movable column, the active column, the support column and the connecting block can be swung, and then the position change component will move, so that the orientation position of the photovoltaic panel can be changed, which is convenient for continuously adjusting the angle of the photovoltaic panel itself, ensuring that it can face the sun at the best angle at different times of the day, thereby absorbing more light energy.
[0008] Preferably, the position changing component includes: two sliding holes, both of which are opened on the outer circular wall surface of the fixed ring, a slider is slidably connected inside the sliding hole, a movable hole is opened on one side of the slider, two rotating holes are opened on the outer circular wall surface of the fixed ring, the movable column is movably connected to the movable hole, two rotating blocks are provided inside the fixed ring, a rotating column is fixedly installed on one side of the rotating block, a connecting hole is opened on one side of the rotating block, the connecting hole is movably connected to the active column, and the rotating column is movably connected to the rotating hole.
[0009] By adopting the above technical solution, through the provision of the movable column, when the driving assembly drives the rotating column and the rotating block to rotate, the active column will rotate inside the connecting hole driven by the rotating block. Since the end faces of the two rotating blocks are facing oppositely, the movable column and the active column are inclined inside the fixed ring. When the rotating block and the rotating column rotate, the movable column and the active column will swing inside the fixed ring. Then, during the movement of the movable column, the two ends of the movable column move in opposite directions, and the movable column will push the slider to slide inside the sliding hole, which can limit the movable column. When the two rotating blocks rotate one circle, the movable column, the active column, the supporting column and the connecting block can drive the mounting frame and the photovoltaic panel to perform 3D spherical motion, which is convenient for reducing cosine loss. Cosine loss refers to the difference between the incident angle of sunlight and the light The larger the angle between the vertical lines on the surface of the photovoltaic panel, the lower the output power of the photovoltaic panel. The photovoltaic panel with 3D spherical motion can continuously adjust the angle to make the sunlight close to vertical incidence, thereby reducing cosine loss and improving photoelectric conversion efficiency. At the same time, under different weather conditions, such as cloudy and rainy days, the radiation intensity and spectral distribution of the sun will change. The photovoltaic panel with 3D spherical motion can adjust the angle and posture to receive as much scattered light and reflected light as possible, thereby reducing the impact of weather changes on power generation efficiency to a certain extent. Furthermore, the photovoltaic panel with 3D spherical motion can use its own rotation or swing to shake off dust, dirt and other impurities on the surface during the movement, which plays a self-cleaning role, keeps the surface of the photovoltaic panel clean, and reduces the decline in power generation efficiency due to dust accumulation.

[0011] By adopting the above technical solution, by setting up a second sprocket, the staff uses a servo motor, and the rotation of the drive shaft of the servo motor will drive the second sprocket to rotate, and then the second sprocket will drive the first sprocket to rotate through the chain, and then the rotation of the first sprocket will drive the rotating column and the rotating block to rotate, thereby facilitating the driving of the movable column and the active column to swing.
[0012] Preferably, the lifting assembly includes: a receiving groove, the receiving groove is opened on the top surface of the support column, the inner bottom surface of the receiving groove is provided with a fixing groove, the inner circular wall surface of the fixing groove is fixedly sleeved with an electric hydraulic rod, and the telescopic rod of the electric hydraulic rod is fixedly installed with the connecting block.
[0013] By adopting the above technical solution, the staff can use the electric hydraulic rod to make the photovoltaic panel move spherically. The extension of the telescopic rod of the electric hydraulic rod will drive the connecting block to move, and then the connecting block will push the mounting frame and the photovoltaic panel to move. Then the mounting frame and the photovoltaic panel can be moved away from the surface of the support frame, so that the position of the mounting frame and the photovoltaic panel is raised, reducing the obstruction of surrounding buildings, trees, etc., so that the photovoltaic panel can receive sunlight more fully, preventing the support frame from interfering with it when the photovoltaic panel moves spherically.
[0014] Preferably, the top surface of the support frame is provided with a plurality of limiting grooves, the bottom surface of the mounting frame is fixedly installed with a plurality of positioning columns, a wave groove is provided on one side of the positioning column, and a plurality of movable grooves are provided on the top surface of the support frame, the movable groove is communicated with the limiting groove, a sliding column is fixedly installed on one side of the inner part of the movable groove, a spring is movably sleeved on the outer circular wall surface of the sliding column, a moving block is movably sleeved on the inner part of the moving groove, a positioning block is fixedly installed on one side of the moving block, a telescopic groove is provided on one side of the moving block, and the telescopic groove is movably sleeved on the sliding column.
[0015] By adopting the above technical solution, through the setting of the positioning column, when the mounting frame and the photovoltaic panel are reset and overlap with the support frame, the positioning column will enter the interior of the limiting groove, thereby facilitating the restriction of the mounting frame to prevent the position change component movement from driving the mounting frame and the photovoltaic panel to move. When the positioning column enters the interior of the limiting groove, the side of the positioning column with the wave groove will squeeze the positioning block, and then the positioning block will be squeezed and push the moving block compression spring to move. When the positioning column stops moving, the spring pushes the moving block and the positioning block to reset, and then the positioning block will rest against the inner wall of the wave groove, thereby facilitating the restriction of the mounting frame and the photovoltaic panel to prevent the mounting frame and the photovoltaic panel from shaking in a windy environment.

[0017] By adopting the above technical solution, through the provision of a protective plate, when the mounting frame and the photovoltaic panel move upward, the mounting frame and the photovoltaic panel will contact the bottom surface of the protective plate and push it, thereby enabling the protective plate to drive the rotating column and the torsion spring to rotate upward, thereby separating the two protective plates; when the mounting frame and the photovoltaic panel are reset, the torsion spring will drive the rotating column and the protective plate to rebound and reset, thereby facilitating shielding and protecting the photovoltaic panel in dusty environments such as dust and sand.

[0019] By adopting the above technical solution, the wind force and speed in the environment where the photovoltaic panels are used can be detected by setting up a wind sensor. When the wind force is strong, the wind sensor will transmit the signal to the PLC controller. After receiving the signal, the PLC controller will start the servo motor and the electric hydraulic rod, so that the mounting frame and the photovoltaic panel are reset to contact the surface of the support frame, increasing the supporting force of the mounting frame and the photovoltaic panel to cope with strong winds.
[0020] Preferably, reinforcement frames are fixedly mounted on both sides of the support column, the reinforcement frames are fixedly mounted to the movable column, a plurality of reinforcement ribs are fixedly mounted on the outer circular wall surface of the movable column, and the reinforcement ribs are fixedly mounted to the active column.
[0021] By adopting the above technical solution, the connection between the movable column, the active column and the support column is strengthened, and the supporting force of the support column is increased.
[0022] In summary, the present invention mainly has the following beneficial effects:
[0023] Through the coordinated movement of the provided base, support frame, mounting frame, photovoltaic panel, mounting seat, fixing platform, fixing ring, movable column, active column, supporting column and connecting block, the mounting frame and photovoltaic panel can be swung, thereby changing the orientation position of the photovoltaic panel, facilitating continuous adjustment of the photovoltaic panel's own angle, ensuring that it can face the sun at the best angle at different times of the day, thereby absorbing more light energy.
[0024] The mounting frame and photovoltaic panels are in 3D spherical motion, which is convenient for reducing cosine loss. The photovoltaic panels with 3D spherical motion can continuously adjust the angle to make the sunlight close to vertical incidence, thereby reducing cosine loss and improving photoelectric conversion efficiency. At the same time, under different weather conditions, such as cloudy and rainy days, the solar radiation intensity and spectral distribution will change. The photovoltaic panels with 3D spherical motion can adjust the angle and posture to receive as much scattered light and reflected light as possible, thereby reducing the impact of weather changes on power generation efficiency to a certain extent.
[0025] During the movement of photovoltaic panels that move on a 3D spherical surface, they can use their own rotation or swing to shake off dust, dirt and other impurities on the surface, playing a self-cleaning role, keeping the surface of the photovoltaic panels clean and reducing the decline in power generation efficiency caused by dust accumulation.

The two movable columns 9 and the active column 10 are arranged in a cross shape, which is used to achieve swinging and have supporting force at the same time. A supporting column 11 is fixedly installed on the top surface of the movable column 9, and a connecting block 12 is arranged inside the supporting column 11. The connecting block 12 is fixedly installed to the bottom surface of the mounting frame 3 for supporting the mounting frame 3.

The driven driving component, the top surface of the support column 11 is provided with a lifting component for allowing the mounting frame 3 and the photovoltaic panel 4 to leave the surface of the support frame 2. Through the provided support column 11, after the staff installs the photovoltaic panel 4, the initial position of the mounting frame 3 and the photovoltaic panel 4 is in an inclined state, and then by using the driving component, the movable column 9, the active column 10, the support column 11 and the connecting block 12 can be swung, and then the position changing component will move, so that the orientation position of the photovoltaic panel 4 can be changed, so as to facilitate the continuous adjustment of the angle of the photovoltaic panel 4 itself, to ensure that it can face the sun at the best angle at different times of the day, so as to absorb more light energy. The position changing component includes two sliding holes 13, and the two sliding holes 13 are both opened on the outer circle of the fixing ring 8. The wall surface, the sliding hole 13 is slidably connected with a slider 14, and a movable hole 15 is provided on one side of the slider 14.

After the column 29 stops moving, the spring 36 pushes the moving block 32 and the positioning block 33 to reset, and then the positioning block 33 will rest against the inner wall of the wave groove 30, so as to facilitate the restriction of the mounting frame 3 and the photovoltaic panel 4 to prevent the mounting frame 3 and the photovoltaic panel 4 from shaking in a windy environment. U-shaped frames 37 are fixedly installed on both sides of the support frame 2, and a protective plate 38 is provided on the top surface of the U-shaped frame 37.

[0047] Working principle: Please refer to Figures 1-15 As shown, through the support column 11, when the staff installs the photovoltaic panel 4, the initial position of the mounting frame 3 and the photovoltaic panel 4 is tilted, and then the movable column 9, the active column 10, the support column 11 and the connecting block 12 can be swung by using the driving component, and then the position change component will move, so that the orientation position of the photovoltaic panel 4 can be changed, so as to facilitate the continuous adjustment of the angle of the photovoltaic panel 4 itself, ensuring that it can face the sun at the best angle at different times of the day, thereby absorbing more light energy.
[0048] When the two rotating blocks 17 rotate one circle, the movable column 9, the active column 10, the supporting column 11 and the connecting block 12 can drive the mounting frame 3 and the photovoltaic panel 4 to perform 3D spherical motion, thereby reducing cosine loss and cosine loss. Chord loss refers to the fact that the larger the angle between the incident angle of sunlight and the vertical line of the surface of the photovoltaic panel 4, the lower the output power of the photovoltaic panel 4. The photovoltaic panel 4 with 3D spherical motion can continuously adjust the angle to make the sunlight close to vertical incidence, thereby reducing cosine loss and improving photoelectric conversion efficiency. At the same time, under different weather conditions, such as cloudy days and rainy days, the radiation intensity and spectral distribution of the sun will change. The photovoltaic panel 4 with 3D spherical motion can adjust the angle and posture to receive as much scattered light and reflected light as possible, thereby reducing the impact of weather changes on power generation efficiency to a certain extent. Furthermore, the photovoltaic panel 4 with 3D spherical motion can use its own rotation or swing to shake off dust, dirt and other impurities on the surface during the movement, which plays a self-cleaning role, keeps the surface of the photovoltaic panel 4 clean, and reduces the decline in power generation efficiency due to dust accumulation.
[0049] By setting up the second sprocket 23, the staff uses the servo motor 22, and the rotation of the drive shaft of the servo motor 22 will drive the second sprocket 23 to rotate, and then the second sprocket 23 will drive the first sprocket 20 to rotate through the chain 24, and then the rotation of the first sprocket 20 will drive the rotating column 18 and the rotating block 17 to rotate, thereby facilitating the driving of the movable column 9 and the active column 10 to swing.
[0050] Through the provided electric hydraulic rod 27, before the staff makes the photovoltaic panel 4 perform spherical motion, by using the electric hydraulic rod 27, the extension of the telescopic rod of the electric hydraulic rod 27 will drive the connecting block 12 to move, and then the connecting block 12 will push the mounting frame 3 and the photovoltaic panel 4 to move, and then the mounting frame 3 and the photovoltaic panel 4 can be moved away from the surface of the support frame 2, so that the position of the mounting frame 3 and the photovoltaic panel 4 is raised, reducing the obstruction of the surrounding buildings, trees, etc., so that the photovoltaic panel 4 can receive sunlight more fully, preventing the support frame 2 from interfering with it when the photovoltaic panel 4 moves spherically.
[0051] Through the provided positioning block 33, when the positioning column 29 enters the interior of the limiting groove 28, the side of the positioning column 29 with the wave groove 30 will squeeze the positioning block 33, and then the positioning block 33 will be squeezed to push the moving block 32 to compress the spring 36 to move. When the positioning column 29 stops moving, the spring 36 pushes the moving block 32 and the positioning block 33 to reset, and then the positioning block 33 will rest against the inner wall of the wave groove 30, thereby facilitating the restriction of the mounting frame 3 and the photovoltaic panel 4 and preventing the mounting frame 3 and the photovoltaic panel 4 from shaking in a windy environment.
[0052] Through the provision of the protective plate 38, when the mounting frame 3 and the photovoltaic panel 4 move upward, the mounting frame 3 and the photovoltaic panel 4 will contact the bottom surface of the protective plate 38 and push it, thereby enabling the protective plate 38 to drive the rotating column 39 and the torsion spring 40 to rotate upward, thereby separating the two protective plates 38. When the mounting frame 3 and the photovoltaic panel 4 are reset, the torsion spring 40 will drive the rotating column 39 and the protective plate 38 to rebound and reset, thereby facilitating shielding and protecting the photovoltaic panel 4 in dusty environments such as dust and sand.
