Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, and in particular to a photovoltaic power generation module. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. It mainly consists of three parts: solar panels (modules), a controller, and an inverter. The main components are composed of electronic devices. Solar cells are connected in series and then encapsulated for protection to form large-area solar cell modules. Combined with components such as a power controller, this forms a photovoltaic power generation device. A patent application with application number 202010869053.2 discloses a photovoltaic module cleaning system for a household photovoltaic power generation system, including a photovoltaic module. A support frame is fixedly connected to the lower surface of the photovoltaic module. A support plate is fixedly connected to the lower surface of the support frame. A support block is fixedly connected to the lower surface of the support plate. A support plate is fixedly connected to the side of the support frame. A fixing plate is fixedly connected to the upper surface of the support plate. A push plate is embedded in the side of the fixing plate. A cleaning layer is fixedly connected to the lower surface of the push plate. In existing technologies, the angle adjustment of photovoltaic panels is done over time. If the photovoltaic panel is blocked by a tall building or utility pole, it is difficult to adjust the angle in real time. Moreover, the cleaning and maintenance of photovoltaic panels are generally done periodically because the working environment of photovoltaic panels is relatively harsh, and the surface is often easily blocked by various debris, which not only affects the power generation efficiency but may also damage the photovoltaic panel. Periodic maintenance will have a certain time gap, and the obstructions on the surface of the photovoltaic panel cannot be cleaned in time. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the problem that in the prior art, there is a certain time gap in the regular maintenance, and the obstructions on the surface of the photovoltaic panel cannot be cleaned in time.

[0004] To address the aforementioned technical problems, the present invention provides a photovoltaic power generation module, comprising: Support frame; A first driving component is mounted on the upper end of the support frame; The second driving member is installed at both ends of the first driving member, and the second driving member is driven to rotate by the first driving member; The mounting bracket is disposed on the outside of the second driving member and is rotated by the second driving member; A photovoltaic panel is fixedly mounted on the surface of the mounting frame; The first testing agency is used to test the area of ​​the photovoltaic panel surface that is blocked; The controller is fixedly mounted on the surface of the support frame and is used to receive signals from the first detection mechanism and control the first drive component and the second drive component to open or close according to the received signals.

[0005] In one embodiment of the present invention, the first driving member includes two mounting platforms, which are respectively mounted on the upper sides of the support frame, and each of the two mounting platforms is rotatably connected to a connecting shaft, and a first driving motor is mounted on the upper surface of each of the two mounting platforms.

[0006] In one embodiment of the present invention, the second driving member includes two frame plates, which are respectively fixedly connected to both ends of the connecting shaft. The mounting bracket and the connecting bracket near the frame plates are provided with matching connecting brackets. The two frame plates are provided with connecting columns inside, and the ends of the connecting columns penetrate the frame plates and are fixedly connected to the connecting brackets. A second driving motor is fixedly installed on the side surface of the two frame plates away from the connecting shaft.

[0007] In one embodiment of the present invention, the first detection mechanism includes two mounting strips, which are respectively mounted on the upper and lower ends of the photovoltaic panel surface, and photoelectric sensors are linearly arrayed on the surfaces of the two mounting strips and the surface of the photovoltaic panel.

[0008] In one embodiment of the present invention, cleaning components for cleaning obstructions on the surface of the photovoltaic panel are also installed on both sides of the photovoltaic panel; The cleaning assembly includes two side mounting strips and two pushing members. The two side mounting strips are slidably connected to the upper and lower surfaces of the photovoltaic panel, respectively. A cleaning strip is fixedly connected to the surface of the two side mounting strips near the photovoltaic panel. The pushing members are used to drive the side mounting strips to move. The inner side of the installation strip is also provided with a second detection mechanism for activating the state of the cleaning component.

[0009] In one embodiment of the present invention, the pushing member includes a servo motor, a drive screw, and a connecting nut. The servo motor is fixedly installed at the upper and lower surface edges of the photovoltaic panel. The drive screw is connected to the drive shaft of the servo motor. The connecting nut is slidably installed on the surface of the photovoltaic panel and is fixedly connected to the side mounting strip. The connecting nut and the drive screw are connected by threads.

[0010] In one embodiment of the present invention, the second detection mechanism includes a laser element and a laser receiver, wherein the laser element is fixedly installed on the side of the mounting strip located below, and the laser receiver is fixedly installed on the side of the mounting strip located below. Both the laser element and the laser receiver are mounted in a linear array, and the mounting positions of the laser element and the laser receiver correspond one-to-one.

[0011] In one embodiment of the present invention, a spraying mechanism for secondary cleaning of adhesive impurities is installed on the side surface of the cleaning strip near the photovoltaic panel; The spraying mechanism includes an electric spray head, which is fixedly installed on the side of the cleaning strip.

[0012] In one embodiment of the invention, the support frame is composed of a base and two vertical rods, and the two mounting platforms are respectively mounted on the tops of the two vertical rods.

[0013] In one embodiment of the present invention, the photovoltaic panel consists of a base and a silicon plate on the surface, and the mounting frame includes two sets of horizontal bars, the base and the horizontal bars being connected by bolts.

[0014] The technical solution of the present invention has the following advantages compared with the prior art: The present invention utilizes the aforementioned cleaning component and first detection mechanism: when the amount of sunlight received by the photoelectric sensor on the surface of the photovoltaic panel is insufficient, the controller activates the first and second driving components to rotate the photovoltaic panel until it reaches a suitable angle. Then, a signal is transmitted to the controller to maintain the current state of the first and second driving components. This allows for automatic adjustment of the photovoltaic panel's angle, ensuring that the light received by the photovoltaic panel is always greater than the light required for normal operation.

[0015] This invention utilizes the aforementioned spraying component and second detection mechanism: when the laser receiver receives obstruction information and initiates the cleaning component, if the laser receiver still shows an obstruction signal, it indicates that debris adheres to the surface of the photovoltaic panel. At this point, the controller moves the cleaning strip, and during this movement, the electric spray head is opened to spray cleaning agent onto the surface of the photovoltaic panel. This not only promptly removes the adhered material but also reduces the number of cleaning agent sprays, thereby reducing corrosion of the photovoltaic panel. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0020] Reference Figure 1 As shown, a photovoltaic power generation module includes: Support frame 1; The first driving component is installed at the upper end of the support frame 1; The second driving component is installed at both ends of the first driving component, and the second driving component is driven to rotate by the first driving component; Mounting bracket 2 is located outside the second driving member and is rotated by the second driving member; Photovoltaic panel 3 is fixedly installed on the surface of mounting frame 2; The first testing agency is used to test the area of ​​the photovoltaic panel 3 surface that is blocked; Controller 4 is fixedly installed on the surface of support frame 1, and controller 4 is used to receive signals from the first detection mechanism and control the first driving component and the second driving component to open or close according to the received signals. In the existing technology, the angle adjustment of the photovoltaic panel 3 is done over time. If the photovoltaic panel 3 is blocked by a tall building or utility pole, it is difficult to adjust the angle in real time. This technical solution can solve the above problems. When the surface of the photovoltaic panel 3 is blocked by other objects, or when the intensity of the received light decreases due to the change of the irradiation angle, the controller 4 activates the first and second driving components to automatically adjust the angle of the photovoltaic panel 3, so as to keep the light received by the photovoltaic panel 3 always within the light range required for normal operation.

[0021] Reference Figure 1 As shown, the first driving component of the present invention includes two mounting platforms 5, which are respectively mounted on the upper sides of the support frame 1, and the interior of each mounting platform 5 is rotatably connected to a connecting shaft 501. The upper surface of each mounting platform 5 is equipped with a first driving motor 502. It should be noted that the drive shaft of the first drive motor 502 and the connecting shaft 501 are connected by a steering gear. The rotation of the connecting shaft 501 is controlled by the first drive motor 502. It should also be noted that the first drive motor 502 and the controller 4 are electrically connected.

[0022] Reference Figure 1 and 6 As shown, the second driving component of the present invention includes two frame plates 6, which are respectively fixedly connected to both ends of the connecting shaft 501. The mounting bracket 2 and the connecting brackets near the frame plates 6 are provided with matching brackets. The two frame plates 6 are provided with connecting columns 601 inside. The ends of the connecting columns 601 penetrate the frame plates 6 and are fixedly connected to the connecting brackets. The second driving motor 602 is fixedly installed on the side surface of the two frame plates 6 away from the connecting shaft 501. It should be noted that the drive shaft of the second drive motor 602 and the connecting column 601 are connected by a steering gear. The rotation of the connecting column 601 and the mounting bracket 2 is controlled by the second drive motor 602. It should also be noted that the second drive motor 602 and the controller 4 are electrically connected.

[0023] Reference Figures 1 to 7 As shown, the first detection mechanism of the present invention includes two mounting strips 7, which are respectively mounted on the upper and lower ends of the surface of the photovoltaic panel 3, and photoelectric sensors 701 are linearly arrayed on the surfaces of the two mounting strips 7 and the surface of the photovoltaic panel 3. It should be noted that the photoelectric sensor 701 and the controller 4 are electrically connected; It should also be noted that the light threshold required for the photovoltaic panel 3 to work normally is L0. When the light threshold is L0, the amount of sunlight received by the photoelectric sensor 701 is X0. The specific working method of the first testing agency is as follows: During the working process, when the amount of sunlight received by the photoelectric sensor 701 on the surface of the photovoltaic panel 3 is greater than XO, it indicates that the light received by the photovoltaic panel 3 is greater than the light threshold L0 required for normal operation. The photoelectric sensor 701 transmits the signal to the controller 4. At this time, the controller 4 controls the first driving element and the second driving element to maintain the current state. As the angle of sunlight changes over time, when the amount of sunlight received by the photoelectric sensor 701 on the surface of photovoltaic panel 3 is less than XO, it indicates that the light received by photovoltaic panel 3 is less than the light threshold L0 required for normal operation. At this time, controller 4 will transmit a signal to start the first drive motor 502 and the second drive motor 602 in the first drive unit. The first drive motor 502 drives the connecting shaft 501 to rotate, and the rotation of the connecting shaft 501 drives the frame plate 6 and the mounting bracket 2 to rotate, thereby causing the photovoltaic panels 3 on both sides to rotate along the axis of the connecting shaft 501 to adjust the pitch angle of the photovoltaic panels 3. Motor 602 drives connecting column 601 to rotate. The rotation of connecting column 601 drives connecting frame and mounting frame 2 to rotate, which in turn drives photovoltaic panel 3 to rotate along the axis of connecting column 601 to adjust the horizontal angle of photovoltaic panel 3 until photovoltaic panel 3 rotates to a suitable angle, so that the amount of sunlight received by photoelectric sensor 701 on the surface of photovoltaic panel 3 is greater than XO. This indicates that the light received by photovoltaic panel 3 is greater than the light threshold L0 required for normal operation. The signal is then transmitted to controller 4, which controls the first and second driving components to maintain the current state. The angle of photovoltaic panel 3 can be automatically adjusted to keep the light received by photovoltaic panel 3 always greater than the light threshold required for normal operation. It should also be noted that in the existing technology, the angle of photovoltaic panels is adjusted in groups. However, when the photovoltaic panels are blocked by tall objects, in most cases only some photovoltaic panels need to be adjusted. If a row of photovoltaic panels is adjusted, it will not only increase energy consumption, but may also reduce the overall area of ​​the photovoltaic panels that receive sunlight. This technical solution can solve the above problems, and its specific working method is as follows: The first driving component can be used to specifically adjust the photovoltaic panels that do not receive sufficient light intensity.

[0024] Reference Figure 1 and Figure 3 As shown, the photovoltaic panel 3 of the present invention is also equipped with cleaning components on both sides for cleaning obstructions on the surface of the photovoltaic panel 3; The cleaning component includes two side mounting strips 8 and two pushers. The two side mounting strips 8 are slidably connected to the upper and lower surfaces of the photovoltaic panel 3, respectively. A cleaning strip 801 is fixedly connected to the surface of the two side mounting strips 8 near the photovoltaic panel 3. The pushers are used to drive the side mounting strips 8 to move. The inner side of the mounting strip 7 is also provided with a second detection mechanism for activating the cleaning component status; It should be noted that the second testing agency is used to test whether the surface of photovoltaic panel 3 is obstructed; In the existing technology, the cleaning and maintenance of photovoltaic panels 3 are generally carried out on a regular basis. This is because the working environment of photovoltaic panels is relatively harsh, and their surfaces are often easily blocked by various debris, which not only affects the power generation efficiency but may also damage the photovoltaic panels. Regular maintenance often involves time gaps, during which obstructions on the surface of photovoltaic panels 3 cannot be cleaned in a timely manner. This technical solution can solve the above problem, and the specific working method is as follows: When the surface of the photovoltaic panel 3 is blocked, the second detection mechanism transmits a signal to the controller 4, which then transmits the signal to the pusher. The pusher moves the cleaning component, which was originally located on the side of the photovoltaic panel 3, along with the photovoltaic panel 3. During the movement, the cleaning strip 801 can clean the obstruction on the surface of the photovoltaic panel 3. After the photovoltaic panel 3 is blocked, the obstruction is processed in a short time.

[0025] Reference Figure 4 As shown, the pusher of the present invention includes a servo motor 9, a drive screw 901 and a connecting nut 902. The servo motor 9 is fixedly installed at the upper and lower surface edges of the photovoltaic panel 3. The drive screw 901 is connected to the drive shaft of the servo motor 9. The connecting nut 902 is slidably installed on the surface of the photovoltaic panel 3 and is fixedly connected to the side mounting strip 8. The connecting nut 902 and the drive screw 901 are connected by threads. The specific working method of the pusher is as follows: During use, when the first detection mechanism receives a signal that there is an obstruction on the photovoltaic panel 3, it transmits the signal to the controller 4. The controller 4 starts the servo motor 9, which drives the drive screw 901 to rotate, thereby driving the connecting nut 902 and the cleaning component to move in contact with the photovoltaic panel 3. It should be noted that the materials selected in the equipment should not interfere with the magnetic force.

[0026] Reference Figure 7 As shown, the second detection mechanism of the present invention includes a laser element 10 and a laser receiver 1001. The laser element 10 is fixedly installed on the side of the mounting strip 7 located below, and the laser receiver 1001 is fixedly installed on the side of the mounting strip 7 located below. Both the laser element 10 and the laser receiver 1001 are installed in a linear array, and the installation positions of the laser element 10 and the laser receiver 1001 correspond one-to-one. The specific working method of the second testing agency during use is as follows: When the light from the laser element 10 illuminates the laser receiver 1001, it indicates that there is no obstruction in the path. When the light from the laser element 10 does not illuminate the laser receiver 1001, it indicates that there is an obstruction in the path. At this time, the laser receiver 1001 transmits a signal to the controller 4, and the controller 4 starts the cleaning component to clean up the obstruction.

[0027] Reference Figure 3 As shown, the cleaning strip 801 of the present invention is equipped with a spraying mechanism for secondary cleaning of adhesive impurities on the side surface near the photovoltaic panel 3. The spraying mechanism includes an electric spray head 11, which is fixedly installed on the side of the cleaning strip 801; It should be noted that the electric spray head 11 and the external liquid storage tank are connected by a hose, and the electric spray head 11 and the controller 4 are electrically connected. In the existing technology, although general obstructions on the surface of photovoltaic panel 3 can be cleaned by ordinary cleaning methods, it is difficult to clean the debris adhering to the surface of photovoltaic panel 3. It is necessary to clean it by spraying cleaning liquid and wiping. However, this cleaning method is also carried out periodically, and there will be a certain time gap. This means that the obstructions on the surface of photovoltaic panel 3 cannot be cleaned in time, which has an impact. Although the impact can be reduced by increasing the number of cleaning times, it is difficult to determine the nature of the obstructions. Increasing the number of times the cleaning liquid is sprayed will also increase the corrosion of photovoltaic panel 3. Under normal conditions, the electric spray head 11 is not activated. When the laser receiver 1001 receives the obstruction information and starts the cleaning component, the laser receiver 1001 still has an obstruction signal, indicating that the surface debris of the photovoltaic panel 3 is adhered to the surface of the photovoltaic panel 3. At this time, the controller 4 controls the cleaning strip 801 to move. During the movement, the electric spray head 11 is opened to spray the cleaning agent onto the surface of the photovoltaic panel 3. This not only removes the adhered material in time, but also reduces the number of times the cleaning agent is sprayed, thereby reducing the corrosion of the photovoltaic panel 3.

[0028] It should also be noted that if there is an obstruction on the corresponding path after the cleaning agency has cleaned it several times, it indicates that the photovoltaic panel 3 may be deformed, and the signal will be transmitted to the staff.

[0029] Reference Figure 1 As shown, the support frame 1 of the present invention is composed of a base and two vertical rods, and two mounting platforms 5 are respectively installed on the top of the two vertical rods.

[0030] Reference Figure 1 As shown, the photovoltaic panel 3 of the present invention consists of a base and a silicon plate on the surface. The mounting frame 2 includes two sets of horizontal bars, and the base and the horizontal bars are connected by bolts.

[0031] Working principle: During operation, when the amount of sunlight received by the photoelectric sensor 701 on the surface of the photovoltaic panel 3 is greater than XO, it indicates that the light received by the photovoltaic panel 3 is greater than the light threshold L0 required for normal operation. The photoelectric sensor 701 transmits the signal to the controller 4. At this time, the controller 4 controls the first driving element and the second driving element to maintain the current state. As the angle of sunlight changes over time, when the amount of sunlight received by the photoelectric sensor 701 on the surface of photovoltaic panel 3 is less than XO, it indicates that the light received by photovoltaic panel 3 is less than the light threshold L0 required for normal operation. At this time, controller 4 controls the first and second driving components to start, driving photovoltaic panel 3 to rotate until photovoltaic panel 3 rotates to a suitable angle, so that the amount of sunlight received by the photoelectric sensor 701 on the surface of photovoltaic panel 3 is greater than XO. This indicates that the light received by photovoltaic panel 3 is maintained in the current state; the angle of photovoltaic panel 3 can be automatically adjusted to keep the light received by photovoltaic panel 3 always greater than the light required for normal operation. When the surface of the photovoltaic panel 3 is blocked, the second detection mechanism transmits a signal to the controller 4, which then transmits the signal to the pusher. The pusher moves the cleaning component, which was originally located on the side of the photovoltaic panel 3, along with the photovoltaic panel 3. During the movement, the cleaning strip 801 can clean the obstruction on the surface of the photovoltaic panel 3. After the photovoltaic panel 3 is blocked, the obstruction is processed in a short time.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
