Description

Technical Field

[0001] This utility model relates to the field of inspection drone technology, specifically a drone for inspecting new energy power stations. Background Technology

[0002] Solar photovoltaic power stations are the most common type of new energy power stations. Inspection drones are key equipment for the intelligent operation and maintenance of photovoltaic power stations. By carrying high-definition cameras, infrared thermal imagers and other equipment, they can achieve efficient, accurate and safe power station inspections. High-definition cameras can accurately capture defects such as minor cracks and delamination on the surface of photovoltaic modules, while infrared thermal imagers can monitor the temperature distribution of modules in real time and quickly identify hot spot effects through thermal imaging, thus providing early warnings of potential faults.

[0003] An investigation revealed that a Chinese utility model patent discloses an inspection drone (publication number: CN219770187U), comprising a drone body, a propeller mechanism, a mounting base, a mounting rod, a protective cover, a protective shell, a bracket, a mounting shell, a camera mechanism, a mounting frame, an electric push rod, and a rotating shaft. The mounting base connects to the drone body; the mounting rod connects to the mounting base, the propeller mechanism connects to the mounting rod, and the protective cover connects to the mounting rod; the mounting shell connects to the drone body, and the brackets are all connected to the mounting shells, with a buffer assembly on the brackets; the electric push rod is rotatably connected to the mounting shell, and a drive assembly is provided on the mounting shell; the mounting frame connects to the electric push rod, the camera mechanism has a mounting part, the mounting part is rotatably connected to the mounting frame via a rotating shaft, the mounting frame has a rotating assembly, the rotating assembly is connected to the rotating shaft, and the protective shell connects to the mounting shell. In this utility model, the cooperation of the drive assembly and the rotating assembly allows the camera mechanism to be adjusted at multiple angles for convenient use; when not in use, the electric push rod drives the camera mechanism to rise and retract into the protective shell.

[0004] While the aforementioned patent can adjust the camera angle by rotating the component, each camera needs constant angle adjustment in actual use to resist the reflection problem of the solar panel. This can lead to missed detections due to reflected light when detecting defects on the surface of photovoltaic modules, reducing its detection accuracy. In addition, the stations are mostly installed in remote areas with complex ground conditions, which cannot guarantee horizontal support for the drones. As a result, when the drones temporarily land inside the station, they cannot adapt to the uneven ground for horizontal descent, thus reducing the safety of the drones when landing.

[0005] Therefore, this utility model provides a drone for inspecting new energy power stations to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This utility model provides a drone for inspecting new energy power stations, aiming to solve the problems mentioned in the background art.

[0011] Two sets of support legs are located on the bottom sides of the drone body, and the support legs are used for auxiliary horizontal support of the drone body. Each support leg includes a sleeve and an electric push rod. The sleeve and the adjusting cylinder are both fixedly connected to the bottom of the drone body.

[0018] (III) Beneficial Effects

[0019] The beneficial effects of this application are as follows:

[0020] 1. This utility model, through the setting of the gimbal frame, allows two sets of rotatable high-definition cameras to be installed below it. Thus, when the device detects surface defects of photovoltaic modules, by adjusting the different angles of the two sets of high-definition cameras, the surface light reflection of the photovoltaic module can only affect one set of high-definition cameras, thereby improving the detection accuracy of surface defects of photovoltaic modules and reducing the influence of light reflection.

Detailed Implementation

[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] like Figure 1-4 As shown, this utility model provides a drone for inspecting new energy power stations, including a drone body 1, with a threaded cylinder 11 integrally installed at the bottom of the drone body 1; a gimbal frame 2, which is fixedly connected to the bottom of the threaded cylinder 11 by screws, and two sets of high-definition cameras 3 and one set of infrared integrated cameras 4 are connected to the bottom of the gimbal frame 2, with the infrared integrated camera 4 positioned between the two sets of high-definition cameras 3; and two sets of support legs 5, which are respectively located on both sides of the bottom of the drone body 1, and are used for auxiliary horizontal support of the drone body 1. The support legs 5 include a sleeve 51 and an electric push rod 56. The sleeve 51 and the adjusting cylinder 52 are both fixedly connected to the bottom of the drone body 1, and the adjusting cylinder 52 is inserted into the inside of the sleeve 51 for adjustment. The bottom of the cylinder 52 is fixedly connected to a leg rod 53, and the outer wall of the horizontal end of the adjusting cylinder 52 is fixedly connected to a support plate 55. The lifting end of the electric push rod 56 is fixedly connected to the support plate 55. Through the setting of the support legs 5, the two support legs 5 can provide support with a height difference. Thus, when facing an inclined ground, the height of the two support legs 5 can be adjusted to ensure that the drone body 1 is horizontally supported, thereby improving the stability and safety of the drone body 1 during take-off and landing. At the same time, the device is equipped with two sets of high-definition cameras 3. By setting them at different angles, the influence of light reflection from photovoltaic modules on the detection of surface defects is reduced, so that only one set of high-definition camera 3 can be affected by light reflection, thereby improving the detection accuracy of surface defects of photovoltaic modules.

[0030] Furthermore, the gimbal frame 2 includes a positioning plate 21, which is fixedly connected to the bottom of the threaded cylinder 11 by screws. Two traction plates 22 are arranged above the positioning plate 21. A column 23 is fixedly connected to the bottom center of the traction plate 22, and a support frame 24 is fixedly connected to the bottom of the column 23 by bolts. A micro motor 25 is fixedly connected to the outer wall of the support frame 24, and a rotating shaft 26 is fixedly connected to the output end of the micro motor 25. The rotating shaft 26 is rotatably connected to the support frame 24. With this structure, the rotating shaft 26 can be rotated by the power-driven micro motor 25, thereby adjusting the tilt angle of the high-definition camera 3.

[0031] Furthermore, each set of high-definition cameras 3 has two rotating shafts 26 on its outer wall. A micro motor 25 is fixedly connected to the end of one rotating shaft 26. The two sets of high-definition cameras 3 have different tilt angles. The infrared integrated machine 4 is fixedly connected to the bottom center of the positioning plate 21. By distributing the two sets of high-definition cameras 3 at different angles, the influence of light reflection from the photovoltaic module is avoided, ensuring that one set of high-definition cameras 3 can detect the surface condition of the photovoltaic module and improve its detection accuracy. At the same time, the infrared integrated machine 4 can quickly identify the hot spot effect through thermal imaging and also judge the ground condition through infrared. By judging the ground tilt by the difference in reflected light at different heights, the height of the two side support legs 5 of the drone body 1 in the falling state can be adjusted in advance according to the ground condition to ensure that the drone body 1 descends horizontally.

[0032] Furthermore, threaded rods are provided at the bottom corners of the traction plate 22, and the threaded rods extend to the bottom of the positioning plate 21 and are connected to nuts. Rubber springs 27 are sleeved on the outside of the threaded rods, and the rubber springs 27 abut against the positioning plate 21 and the traction plate 22. The setting of the rubber springs 27 achieves a good buffering effect, avoiding the impact of the flight vibration of the UAV body 1 on the high-definition camera 3.

[0033] Furthermore, the adjusting cylinder 52 has an H-shaped structure, and a set of sleeves 51 are fitted at both ends of the top of the adjusting cylinder 52. Buffer sleeves 54 are fixedly connected to the outer walls of both ends of the leg rod 53. The axes of the sleeves 51, adjusting cylinder 52, and electric push rod 56 are on the same horizontal plane. The maximum drop angle between the two sets of leg rods 53 is thirty-five degrees. By energizing and pulling the electric push rod 56, the adjusting cylinder 52 can be adjusted up and down, thereby realizing the height adjustment of the leg rod 53. Thus, by adjusting the height difference between the two leg rods 53, it can descend to ground with different inclination angles.

[0034] Working principle: When the device performs flight inspection, it can simultaneously detect the surface condition of photovoltaic modules by setting two sets of high-definition cameras 3 at different angles. Even if the photovoltaic modules produce light reflection, the reflection angle can only affect one set of high-definition cameras 3, thereby improving the detection accuracy of surface defects. At the same time, by setting the support legs 5 on both sides, the device can be adjusted to different heights by adjusting the legs 53 on both sides, so that the device can perform horizontal take-off and landing operations on different ground surfaces, thereby improving the safety of the device's take-off and landing.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
