Description

Technical Field

[0001] This utility model relates to the field of inspection device technology, specifically to a drone inspection device. Background Technology

[0002] Unmanned aerial vehicle (UAV) inspection is a technology that uses unmanned aerial vehicles to autonomously and non-contactly monitor and collect data on specific areas or facilities. Its core lies in replacing traditional manual inspections or fixed monitoring equipment by leveraging the advantages of high-altitude perspective, flexible maneuverability, and real-time data transmission. It improves inspection efficiency while ensuring safety and is widely used in fields such as energy, transportation, agriculture, and urban management.

[0003] For example, the authorized patent with announcement number CN 215155658 U (Intelligent Traffic Unmanned Aerial Vehicle Inspection Equipment) includes an inspection fuselage, a support assembly, and a wing assembly; a camera lens embedded in the upper part of the inspection fuselage; a support assembly connected to the lower left and right sides of the inspection fuselage; wing assemblies located at the four corners of the inspection fuselage; an auxiliary support frame connected to the lower middle part of the inspection fuselage, with a fixing buckle fixed to the outer side of the upper end of the auxiliary support frame; legs; a base rod fixed to the bottom end of the legs; and a sleeve connected to the front and rear ends of the base rod, with a pad connected to the lower end of the sleeve.

[0004] While the aforementioned existing technology reduces wear on the base rod by having the drone directly contact the ground through its elastic feet when it descends, it only has a single forward-facing camera and cannot perform multi-directional video acquisition from dual perspectives. This results in the inability to obtain information from multiple directions during inspections, making it easy to miss key defect features and impractical. Therefore, the market urgently needs to develop drone inspection devices to help people solve existing problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-5 An embodiment of this utility model provides a drone inspection device, including a drone body 1, an equipment box 3 below the drone body 1, a main camera 4 fixedly installed at the front end below the equipment box 3, a secondary camera 8 installed at the rear end below the equipment box 3, and an adjustment mechanism 9 above the secondary camera 8. The adjustment mechanism 9 includes an adjustment box 901 and a mounting frame 902. The mounting frame 902 is rotatably installed below the adjustment box 901. The adjustment box 901 is fixedly connected to the equipment box 3. The mounting frame 902 is configured as an inverted U-shaped plate, and the secondary camera 8 is rotatably installed inside the mounting frame 902.

[0026] During the inspection, the main camera 4 can capture video from the front, while the secondary camera 8 can rotate horizontally and vertically through the adjustment mechanism. By flexibly adjusting the shooting angle, it can acquire video information from multiple directions, which is beneficial to the accuracy of inspection data and increases its practicality.

[0027] Please see Figure 3 and Figure 4 A partition 11 is fixedly installed inside the regulating box 901. A drive shaft 12 is rotatably installed below the partition 11. The lower end of the drive shaft 12 extends to the lower part of the regulating box 901 and is fixedly connected to the mounting bracket 902. A motor 13 is fixedly installed above the partition 11. The output end of the motor 13 is fixedly connected to the drive shaft 12. A gear 14 is fixedly installed on the outside of the drive shaft 12. A rotating shaft 15 is provided on one side of the drive shaft 12 and is rotatably connected to the partition 11. A gear 2 16 is fixedly installed on the outside of the rotating shaft 15. Gear 14 and gear 2 16 are meshed together. An encoder 17 is fixedly installed above the partition 11. The measuring end of the encoder 17 is fixedly connected to the rotating shaft 15.

[0028] The lower end of the drive shaft 12 is fixedly connected to the mounting plate 902, and the upper end is connected to the output end of the motor 13. After the motor 13 starts, it can drive the drive shaft 12 to rotate, thereby driving the mounting plate 902 to rotate horizontally, so that the secondary camera 8 can adjust the viewing angle in the horizontal direction. The rotating shaft 15 is connected to the drive shaft 12 through gear 14 and gear 2 16. When the drive shaft 12 rotates, the rotating shaft 15 rotates synchronously. The measuring end of the encoder 17 is fixedly connected to the rotating shaft 15, which can measure the rotation angle of the rotating shaft 15 in real time. This is beneficial for monitoring the horizontal rotation angle of the secondary camera 8 and enhances the adaptability and reliability of the UAV inspection device in complex inspection scenarios.

[0029] Please see Figure 4 A motor housing 10 is fixedly installed at the front end of the mounting plate 902. A second motor 18 is installed inside the motor housing 10 and is fixedly connected to the mounting plate 902. The output end of the second motor 18 is fixedly connected to the secondary camera 8. An encoder 2 is fixedly installed at the rear end of the mounting plate 902 and the measuring end of the encoder 2 is fixedly connected to the secondary camera 8.

[0030] This allows motor 2 18 to directly drive the secondary camera 8 to rotate vertically inside the mounting bracket 902. The secondary camera 8 can flexibly adjust its vertical shooting angle as needed to obtain more comprehensive and three-dimensional video information. The encoder 2, which is fixedly installed at the rear of the mounting bracket, can monitor the vertical rotation angle of the secondary camera 8 in real time, increasing its practicality.

[0031] Please see Figure 2 A mounting top plate 6 is fixedly installed on the top of the equipment box 3. The mounting top plate 6 is set as an inverted U-shaped plate. A mounting base 5 is fixedly installed on the top of the mounting top plate 6 by bolts. The mounting base 5 is set as a U-shaped plate. The mounting base 5 is fixedly connected to the drone body 1. Landing gears 2 are symmetrically fixedly installed on both sides below the drone body 1.

[0032] The combination of the inverted U-shaped mounting top plate 6 and the U-shaped mounting base 5 enables quick assembly and disassembly of the equipment box 3, increasing its practicality.

[0033] Please see Figure 3 and Figure 5 The equipment box 3 has a backup power supply and an intelligent processor 20 fixedly installed inside. A speaker 7 is fixedly installed at the bottom of the equipment box 3, and a lidar 19 is fixedly installed at the front. The lidar 19 uses a laser beam for distance measurement and environmental perception, accurately acquiring three-dimensional spatial information of the inspection area and constructing a detailed environmental model. The input of the intelligent processor 20 is connected to the output of the main camera 4, the secondary camera 8, and the lidar 19, respectively. The output of the intelligent processor 20 is connected to the speaker 7 and the input of the wireless transmission module 21, respectively. The output of module 21 is connected to the input of inspection terminal 22. Through the wireless transmission module 21, the inspection information processed by the intelligent processor 20 can be transmitted to the inspection terminal 22 in real time and quickly, so that ground operators can obtain first-hand information from the inspection site in a timely manner without waiting for the equipment to return or manually transmitting data, which greatly shortens the information feedback time and improves the timeliness of inspection work. The setting of backup power supply provides reliable power guarantee, which improves the reliability and stability of inspection work. At the same time, the setting of voice speaker 7 can play inspection instructions, prompts or warning sounds in real time, which increases practicality.

[0034] Furthermore, during drone inspections, the intelligent processor 20 enables the drone to process inspection information intelligently on its own, eliminating the need to transmit all data to the ground terminal for processing. This significantly reduces the pressure on data transmission and improves the efficiency of information processing. When special conditions or abnormal situations occur during the inspection, the intelligent processor on the drone can quickly make a judgment and automatically provide warning information through the voice module, promptly notifying operators or relevant personnel to take measures. This achieves rapid response and timely handling. This dual-terminal structure, formed with the ground terminal, gives the drone inspection system stronger autonomous decision-making and emergency response capabilities. It can independently complete inspection tasks to a certain extent, reducing the need for manual intervention and improving the automation and intelligence of inspection work.

[0035] Working Principle: During use, the drone body 1 carries the equipment box 3 for aerial inspection operations. During the inspection flight, the main camera 4 and the secondary camera 8 under the equipment box 3 work together to form a dual-view acquisition structure. The main camera 4 is fixed to capture the forward field of view, while the secondary camera 8 can be flexibly adjusted to multiple angles through the adjustment mechanism 9. At the same time, the lidar 19 inside the equipment box 3 uses laser beams to measure distance and perceive the environment, acquire three-dimensional spatial information of the inspection area and build an environmental model. The inspection information collected by the main camera 4, the secondary camera 8 and the lidar 19 is transmitted to the intelligent processor 20. The intelligent processor 20 intelligently processes this information and judges the inspection status. When a special status or abnormal situation occurs, the intelligent processor 20 automatically prompts a warning through the voice speaker 7. At the same time, the processed inspection information is transmitted in real time and quickly to the inspection terminal 22 via the wireless transmission module 21. Ground operators can obtain first-hand information from the inspection site in a timely manner, improving the timeliness of the inspection work.
