Technical Field

[0001] This utility model relates to the field of photovoltaic module cleaning technology, specifically to a photovoltaic module cleanliness monitoring device. Background Technology

[0002] Currently, the cleanliness of photovoltaic (PV) modules has a significant impact on their power generation efficiency. Dust and other debris covering the surface of PV panels can significantly reduce their power generation efficiency. Therefore, monitoring the cleanliness of PV modules has become particularly important.

[0003] Currently, the monitoring of photovoltaic modules mostly uses visual modules and spectrometers. However, visual modules and spectrometers are usually directly exposed to the outside and are easily damaged or contaminated, which seriously affects the accuracy and effectiveness of monitoring. In order to solve the above problems, this utility model provides a photovoltaic module cleanliness monitoring device. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a photovoltaic module cleanliness monitoring device, which includes a frame and a barrier door. When the vision module and spectrometer are not in operation, the device can protect them from damage or contamination, thus preventing them from affecting the monitoring results.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This invention provides a photovoltaic module cleanliness monitoring device, such as... Figures 1 to 4 As shown.

[0030] Example 1:

[0031] A photovoltaic module cleanliness monitoring device includes a support base, which is installed on a photovoltaic bracket. A connecting seat 1 is installed on the support base, and a motor 2 is installed inside the connecting seat 1. A frame 3 is rotatably installed on the connecting seat 1. The frame 3 is fixedly connected to the motor shaft of the motor 2. The rotation of the motor shaft of the motor 2 can drive the frame 3 to rotate.

[0032] One end of the frame 3 has an opening, and a mounting plate 5 is slidably installed inside the frame 3. A vision module 6 and a spectrometer 7 are mounted on the mounting plate 5 (the vision module 6 can identify obvious dirt and impurities on the surface of the photovoltaic panel, such as bird droppings and leaves, and the spectrometer 7 can accurately measure the reflectivity and transmittance of the photovoltaic panel surface and monitor dust on the photovoltaic panel). A door 4 is hinged at the opening of the frame 3. When the vision module 6 and the spectrometer 7 are not working, the door 4 is in a closed state, and the inside of the frame 3 remains sealed, which can protect the vision module 6 and the spectrometer 7. When the vision module 6 and the spectrometer 7 are working, the mounting plate 5 slides outward of the frame 3, opening the door 4, allowing the vision module 6 and the spectrometer 7 to extend smoothly from the inside of the frame 3, thereby monitoring the surface of the photovoltaic panel.

[0033] A frame 10 is fixedly connected to the lower side of the mounting plate 5. The frame 10 is slidably connected to a limiting rod 11 fixedly connected inside the frame 3. The limiting rod 11 can limit the sliding of the mounting plate 5 through the frame 10, so that the mounting plate 5 can slide stably within a specified range. The mounting plate 5 is driven to slide inside the frame 3 by an electric push rod 16 installed inside the frame 3.

[0034] The angle of the connecting seat 1 can be adjusted by the support base, thereby adjusting the angle between the frame 3 and the photovoltaic panel, so that the vision module 6 and the spectrometer 7 can better monitor the photovoltaic panel. By starting the motor 2, the frame 3 can swing back and forth on the connecting seat 1, so that the vision module 6 and the spectrometer 7 can cover the entire photovoltaic panel during monitoring, and monitor the entire photovoltaic panel.

[0035] Motor 2, vision module 6, spectrometer 7 and electric actuator 16 are connected to an external power source via cables. The start and stop of motor 2, vision module 6, spectrometer 7 and electric actuator 16 can be controlled by the same terminal of the control circuit.

[0036] Both the vision module 6 and the spectrometer 7 are existing technologies and are now widely used, so this utility model will not elaborate on them. For example, the vision recognition module 6 can be the WSD-5020-WDR model, and the spectrometer 7 can be the AIOX2000-11 model.

[0037] Example 2:

[0038] The support base includes a base 18, on which multiple fixing plates are fixedly connected. The fixing plates have through holes, allowing bolts to be threaded through the through holes and connected to the photovoltaic bracket during installation, thus mounting the base 18 onto the photovoltaic bracket. The base 18 has a platform 17, one end of which is hinged to the base 18. Multiple support rods 8 are hinged to the side of the platform 17 closest to the base 18. The lower ends of the support rods 8 are hinged to slide rods 9 slidably mounted on the base 18 (the end of the support rod 8 away from the platform 17 is the lower end). The slide rods 9 are threadedly connected to screws 15 rotatably mounted on the base 18. One end of the screws 15 extends through the side wall of the base 18 to the outside of the base 18. By rotating the screws 15, the slide rods 9 can slide on the base 18, thereby controlling the rotation of the platform 17 via the support rods 8, and thus adjusting the angle between the frame 3 and the photovoltaic panel.

[0039] Example 3:

[0040] Both ends of the upper side of the mounting plate 5 are fixedly connected to the top rods 12. The top rods 12 are in the shape of "┐", with one end fixedly connected to the mounting plate 5 and the other end attached to the door 4. When the mounting plate 5 slides to the outside of the frame 3, the top rods 12 will first contact the door 4 and push the door 4 open, so that the vision module 6 and the spectrometer 7 will not collide or resist the door 4.

[0041] Furthermore, in order to ensure that the gate 4 can still close stably after the angle between the frame 3 and the photovoltaic panel is adjusted, magnets 13 are respectively installed on the inner side walls at both ends of the opening of the frame 3, and iron plates 14 adapted to the magnets 13 are installed on the inner side of the gate 4. When the gate 4 is not pushed by the top rod 12, the gate 4 will be stably closed under the action of the magnets 13 and the iron plates 14, thereby protecting the vision module 6 and the spectrometer 7.

[0042] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
