Abstract
Description
Technical Field
[0001] This utility model belongs to the field of photovoltaic power generation operation and maintenance, specifically a cleaning device for solar panels based on drones. Background Technology
[0002] In the field of photovoltaic power generation operation and maintenance, using drones equipped with cleaning components to clean solar panels has become an important technical means to improve power generation efficiency.
[0003] Existing cleaning equipment often uses fixed installation structures for its cleaning components, which cannot adaptively adjust to the actual tilt angle of the solar panels. Since the tilt angle of solar panels varies significantly in different installation scenarios, fixed-angle cleaning components cannot maintain a tight fit with the panel surface, leading to blind spots during cleaning, especially at the edges of the panel and in areas with large tilt angles. Dust, fallen leaves, and other foreign objects are difficult to remove completely, directly affecting the photovoltaic conversion efficiency of the solar panels. Furthermore, existing drone cleaning equipment generally lacks precise foreign object detection methods. Most devices rely solely on operator visual inspection or simple image recognition technology to determine the presence of foreign objects on the solar panel surface. This detection method is not only inefficient but also susceptible to factors such as lighting conditions and the similarity of the foreign object's color to the panel surface, making it prone to missed detections or misjudgments. For foreign objects with small obstruction areas or indistinct colors, traditional detection methods struggle to accurately identify them, resulting in a lack of targeted cleaning and an inability to promptly remove key foreign objects affecting power generation efficiency, thus reducing overall cleaning efficiency and the power generation performance of the solar panels. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a solar panel cleaning device based on a drone, which solves the problems of existing cleaning devices being unable to adapt to the tilt angle of the panel and having insufficient accuracy in detecting foreign objects.

[0023] Preferably, the drone is equipped with a control system, which is used to receive data from the foreign object identification and monitoring module and the ranging and tilt detection module, and to control the adjustment components and cleaning.
[0024] Compared with the prior art, the present invention has the following beneficial effects:
[0025] 1. This utility model, through the cooperation of the distance measuring tilt detection module and the adjustment component, can flexibly adjust the relative angle of the cleaning component according to the installation tilt angle of the solar panel, and at the same time detect the relative position of the cleaning component and the solar panel in real time, ensuring that the cleaning cloth is always in contact with the solar photovoltaic panel, effectively improving the cleaning effect and avoiding cleaning blind spots.
[0026] 2. This utility model uses an infrared thermal imaging camera on the foreign object identification and monitoring module to quickly identify the area covered by foreign objects on a large solar panel. Then, it uses an infrared high-definition camera to confirm the specific situation of areas with abnormal temperatures, avoiding misjudgment. Moreover, this detection method is not affected by day or night and can effectively detect foreign objects on the solar panel in a timely manner, providing accurate guidance for cleaning work and improving cleaning efficiency and solar panel power generation efficiency.

[0033] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0034] As attached Figure 1 To be continued Figure 4 As shown:
[0035] This utility model provides a drone-based solar panel cleaning device, including a drone 1. Several landing support frames 2 are mounted on the underside of the drone 1 for stable take-off and landing. A foreign object detection and monitoring module 3 is mounted on the side of the drone 1. This module employs a dual-camera design, incorporating both an infrared thermal imaging camera and an infrared high-definition camera, to monitor and report foreign objects on the solar panel. A cleaning component 5 is mounted at the lower end of the drone 1 for cleaning foreign objects from the solar panel. An adjustment component 4 is located between the cleaning component 5 and the drone 1 to adjust the angle and distance of the cleaning component 5 relative to the solar panel.
[0036] As attached Figure 1 To be continuedFigure 3 As shown: The adjustment component 4 includes a mounting plate 401 installed on the drone 1. The mounting plate 401 is fixed to the bottom of the drone 1 with bolts, providing a mounting base for the adjustment component 4. Below the mounting plate 401 is a mounting plate 402. Several telescopic push rods 403 are hinged between the mounting plate 402 and the mounting plate 401. The telescopic push rods 403 can be selected from servo motors, hydraulically driven, or pneumatically driven telescopic cylinders. The angle and position of the mounting plate 402 are adjusted by the telescopic movement of the push rods 403. A ranging and tilt detection module 6 is installed on the mounting plate 402. The ranging and tilt detection module 6 consists of several arrayed ranging sensors used to detect the angle and distance of the cleaning component 5 relative to the solar panel. The module determines whether the mounting plate 402 and the solar panel are parallel based on whether the distances detected by the ranging sensors are equal.
[0037] As attached Figure 1 To be continued Figure 3 As shown: The cleaning assembly 5 includes a turntable 501 rotatably mounted on a mounting plate 402. Several cleaning plates 502 are arranged on the side of the turntable 501. The upper end of the turntable 501 passes through the mounting plate 402 and is connected to a rotary motor 503. Cleaning cloths are provided on the bottom surfaces of both the turntable 501 and the cleaning plates 502. The rotary motor 503 drives the turntable 501 and the cleaning plates 502 to rotate, thereby cleaning the solar panels. The cleaning cloths can be either a soft-bristled mop or a rag.
[0038] The mounting plate 401 is equipped with a voice module 7, which uses TTS speech synthesis technology and supports high-definition voice broadcasting within a 10m range. The work area is monitored by an infrared high-definition camera, and the feedback is sent from the drone control system to the remote control platform. At the same time, it determines whether the operators are wearing work clothes, safety helmets, etc., and provides on-site voice reminders for violations such as not wearing safety helmets or work clothes.
[0039] Working Principle: When the equipment starts working, the drone 1, carrying all components, flies to the solar panel area. The foreign object detection and monitoring module 3 uses an infrared thermal imaging camera and an infrared high-definition camera to detect foreign objects on the solar panel and transmits the detected foreign object information to the control system. The ranging and tilt detection module 6 continuously detects the angle and distance between the cleaning component 5 and the solar panel and feeds the data back to the control system. The infrared high-definition camera monitors the work area, and the drone control system feeds the data back to the remote control platform. At the same time, it determines whether the operators are wearing work clothes, safety helmets, etc., and provides on-site voice reminders for violations such as not wearing safety helmets or work clothes.
[0040] Based on the information about foreign objects and distance / angle data, the control system controls the extension and retraction of the telescopic push rod 403 of the adjustment component 4, which in turn drives the mounting plate 402 to adjust its angle and position, thereby ensuring that the cleaning cloth of the cleaning component 5 fits tightly against the surface of the solar panel. Next, the control system starts the rotary motor 503, which drives the turntable 501 and the cleaning plate 502 to rotate, allowing the cleaning cloth to sweep away foreign objects from the surface of the solar panel, achieving efficient cleaning of the solar panel.
