Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic inspection, in particular to a photovoltaic scanning device. Background Art

[0002] Photovoltaic power stations are usually composed of a large number of photovoltaic modules. These modules are scattered over a wide area and exposed to the outdoor environment for a long time. They are easily affected by the natural environment such as wind, sand, rain, snow, bird droppings, etc., which can lead to surface contamination, obstruction, damage, etc. of the modules, thereby affecting power generation efficiency. Therefore, personnel inspection and maintenance are required.

[0003] Traditional photovoltaic panel scanning requires a long training time and high labor costs. PV power plants are often located in open, outdoor areas such as deserts, Gobi Desert, and mountainous regions, where climatic conditions are often harsh, including high temperatures, freezing temperatures, strong winds, and sandstorms. Inspectors must work long hours in these environments, which is not only physically demanding but also susceptible to weather fluctuations. Inclement weather, such as rain and snow, can severely hinder inspection work. PV power plants occupy vast areas, with numerous and densely distributed photovoltaic panels. For example, a large-scale PV power plant can span thousands or even tens of thousands of acres, housing hundreds of thousands or even millions of panels. Given such a large scale, inspectors must traverse various areas on foot or by vehicle, inspecting each panel individually. This demanding work is not only time-consuming and labor-intensive, but can also easily lead to fatigue and oversight, compromising the accuracy and comprehensiveness of scanning.

[0004] GIS 3D scanning is achieved through 3D laser scanning technology, also known as real-scene replication technology. It uses the principle of laser ranging and high-speed laser scanning measurement methods to obtain high-precision 3D coordinate data and a large amount of spatial point information on the surface of the measured object over a large area and with high resolution. GIS 3D scanning can be performed well by using drones combined with 3D scanning camera equipment. Summary of the Invention

[0021] Example 1:

[0022] like Figures 1 to 4 As shown, a photovoltaic scanning device includes an unmanned aerial vehicle (UAV) body 1 for inspecting photovoltaic systems. An assembly housing 2 is fixedly mounted to the bottom of the frame of the UAV body 1. A first rotating shaft 7 is rotatably mounted to the bottom of the assembly housing 2 via a bearing. The first rotating shaft 7 is vertically arranged and driven by a drive mechanism disposed within the assembly housing 2. An access hatch can be provided on one side of the assembly housing 2. The hatch is provided with a removable door panel, which is screwed to the side wall of the assembly housing 2, allowing the assembly housing 2 to be opened for inspection or closed for sealing.

[0023] The drive mechanism can be a reduction motor. In this embodiment, the drive mechanism includes a second motor 10 disposed within the assembly housing 2. A first gear 11 is provided on the output shaft of the second motor 10, and a second gear 12 is provided on the first rotating shaft 7, which meshes with the first gear 11. Parameters such as the number of teeth and module of the first gear 11 must match those of the second gear 12 to achieve efficient power transmission. The second gear 12 is fixed to the first rotating shaft 7 and meshes with the first gear 11. When the second motor 10 drives the first gear 11 to rotate, the power is transmitted to the second gear 12 through the meshing action between the gears, thereby driving the first rotating shaft 7 and components such as the assembly frame 3 and the camera scanner 6 mounted thereon to rotate horizontally.

[0024] 3, second rotating shaft 8 is installed on the assembling frame 3 by bearing rotation, one of them second rotating shaft 8 is connected with the output shaft of first motor 9 by coupling, first motor 9 is arranged on assembling frame 3 outside, specifically be installed on the mounting plate of assembling frame 3 one side, as the power source that second rotating shaft 8 rotates, the selection of first motor 9 should consider factors such as its output power, speed range and durability, coupling is fixed on the output shaft of first motor 9, is used for the power transfer of first motor 9 on the second rotating shaft 8; After the first motor 9 starts, drive coupling to rotate by its output shaft, coupling transmits rotary power to the second rotating shaft 8 that is fixedly connected with it again, because second rotating shaft 8 is fixedly connected with assembling frame 4, so assembling frame 4 can rotate thereupon, and then realizes the adjustment of camera scanner 6 pitch angle.Second rotating shaft 8 is rotationally installed on the assembling frame 3 symmetrically, and this symmetrical layout helps to realize the steady adjustment of assembling frame 4 in pitch direction. One end of the second rotating shaft 8 close to each other is fixedly connected to the assembly seat 4. Therefore, when the second rotating shaft 8 rotates, it will drive the assembly seat 4 and the assembly block 5 and camera scanner 6 installed on the assembly seat 4 to rotate together, thereby achieving adjustment of the pitch angle.

[0025] The camera scanner 6 is mounted on the assembly seat 4 . In this embodiment, the camera scanner 6 is a high-definition camera scanner 6 .

[0026] like Figure 3 and 4 As shown, the assembly seat 4 is provided with a slide groove 401 that cooperates with the assembly block 5. The slide groove 401 is a T-shaped slide groove, and the assembly block 5 is a T-shaped block adapted to the slide groove 401. A connecting plate is provided at the lower end of the assembly block 5. The assembly block 5 and the connecting plate are an integrated structure, and the connecting plate is connected to the camera scanner 6 by bolts.

[0027] Preferably, a threaded hole adapted to the limit screw 14 is provided on the top of the assembly block 5, the assembly seat 4 is connected to the assembly block 5 through the limit screw 14, and a through hole or threaded hole adapted to the limit screw 14 is provided on the upper side of the assembly seat 4 to realize a detachable connection between the assembly block 5 and the assembly seat 4.

[0028] In this embodiment, the drone body 1 serves as the core carrier of the entire inspection system. The drone body 1 has the characteristics of strong flexibility and wide coverage. It can quickly cross various areas of the photovoltaic power station without being restricted by terrain, greatly reducing the outdoor working time and physical exertion of the inspection personnel. The drone's GIS three-dimensional technology uses GIS data to plan the drone inspection route in advance to ensure coverage of all photovoltaic areas while avoiding obstacles and no-fly zones; autonomous flight and data collection: the drone automatically flies according to the preset route, and the camera scanner scans and collects the surface image, temperature information and three-dimensional spatial data of the photovoltaic panel; the drone is equipped with a camera scanner to scan the photovoltaic power station, and then three-dimensional modeling is carried out to realize inspection; through wireless transmission technology The technology transmits collected data back to a ground control station or cloud server in real time. Monitoring personnel can view the scanning status in real time and identify problems promptly. It offers the advantages of high efficiency, high precision, and low cost, enabling rapid acquisition of large amounts of geographic data. It is particularly suitable for areas that are difficult to reach or beyond the reach of traditional ground mapping. The assembly shell 2 is fixed to the bottom of the UAV body 1 frame, providing a stable mounting base for the various components below. The design of the assembly shell 2 takes into account wind resistance and stability, ensuring the stability of the UAV during flight. By rotating the first rotating shaft 7 mounted on the assembly shell 2, the assembly frame 3 can achieve flexible horizontal steering. This design allows the camera scanner 6 to easily align with the target photovoltaic panel, regardless of its orientation. The assembly base 4 is rotatably mounted on the assembly base 3, and its pitch angle is adjustable. The assembly block 5 is slidably mounted on the assembly base 4 and secures the camera scanner 6. This design allows the camera scanner 6 to be precisely adjusted vertically to obtain the optimal shooting angle and field of view. As a key inspection component, the camera scanner 6 features high-definition capture and real-time transmission capabilities. It can clearly capture detailed information about photovoltaic panels, such as surface stains, cracks, and obstructions, and transmit this data in real time to a ground control station or cloud server for analysis and processing. Drone inspections are fast and cover a wide area, significantly shortening inspection cycles and improving efficiency. They also reduce inspectors' reliance on specialized knowledge and experience, lowering labor costs and reducing their workload. The wireless high-definition camera scanner and real-time transmission technology accurately capture detailed information about photovoltaic panels, improving the accuracy and comprehensiveness of inspections. Drone inspections are not restricted by inclement weather or terrain, and can operate normally in harsh environments such as high temperatures, severe cold, and strong winds, ensuring the continuity and stability of inspections.
