[0017] 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.

[0018] Please see Figure 1-5 This utility model provides an embodiment of a modularly assembled UAV power observation frame, comprising a frame plate 1 that can be installed at the bottom of the UAV landing gear 5. A turntable 21 is rotatably connected to the frame plate 1, and the turntable 21 is provided with several assembly components 3. The frame plate 1 is also provided with a drive component 4. Each assembly component 3 includes two symmetrically arranged L-shaped blocks 31, and spring clips 32 are riveted to the L-shaped blocks 31. The spring clips 32 can be engaged in the slots of the housing of an infrared thermal imager or a visible light camera. The middle part of the bottom of the frame plate 1 is arched upward to avoid obstacles on the ground. This structure, by setting multiple assembly components 3 on the turntable 21, allows for quick installation or replacement of observation equipment, improving operational flexibility. At the same time, the upward arching design of the middle part of the frame plate 1 effectively avoids the risk of collision caused by ground protrusions or weeds during low-altitude flight or take-off and landing of the UAV, improving the safety and adaptability of equipment operation.

[0019] Please see Figure 1-5 A further embodiment of this solution is as follows: a gear 22 is rotatably connected to the frame plate 1, and a turntable 21 is bolted to the axial surface of the gear 22. The turntable 21 is rigidly connected to the gear 22, so that the rotation of the turntable 21 is directly driven by the gear 22. The transmission relationship is clear, the structure is compact, which helps to improve the synchronization and stability of angle adjustment, and also facilitates assembly and maintenance.

[0020] Please see Figure 1-4 A further solution based on this embodiment is as follows: the drive component 4 includes a rack 45 that can move back and forth, and the rack 45 can drive the gear 22 to rotate. By using the meshing of the rack 45 and the gear 22, linear motion is converted into rotational motion. The structure is simple and reliable, the control logic is clear, and it is easy to accurately adjust the azimuth angle of the turntable 21 through the motor 43 to meet the needs of different inspection angles. This avoids installing the motor 43 at the bottom of the frame plate 1, reducing the risk of flight interference.

[0021] Please see Figure 1-4A further embodiment of this solution is as follows: the rack 45 is provided with a dovetail groove 452, and a dovetail block 44 corresponding to the dovetail groove 452 is installed on the frame plate 1 by bolts. The cooperation between the dovetail groove 452 and the dovetail block 44 not only plays a good guiding role in the movement of the rack 45, but also effectively prevents it from deflecting or leaving the track during the movement, thereby ensuring the smoothness of the transmission process and the repeatability of the positioning accuracy.

[0022] Please see Figure 1-4 A further solution based on this embodiment is as follows: Two fixing blocks 41 are provided on the frame plate 1, and a screw 42 is rotatably connected between the two fixing blocks 41. A motor 43 for driving the screw 42 to rotate is installed on one of the fixing blocks 41. The screw 42 is driven to rotate by the motor 43, forming a lead screw transmission mechanism. This mechanism can efficiently convert the rotational motion of the motor 43 into the linear displacement required by the rack 45. The overall structure is reasonably laid out, occupies little space, and is suitable for scenarios where the payload of the UAV is limited.

[0023] Please see Figure 2-5 A further solution based on this embodiment is as follows: a nut seat 451 is integrally formed on the rack 45, and the nut seat 451 can be screwed to the screw 42. The nut seat 451 is integrally formed with the rack 45, which avoids loosening or errors caused by additional connecting parts, enhances the overall rigidity of the structure, and simplifies the assembly process.

[0024] Please see Figure 2-5 A further solution based on this embodiment is as follows: the UAV landing gear 5 is provided with mounting holes 51, through which connecting bolts 12 can pass and connect to the frame plate 1. By using the existing mounting holes 51 of the landing gear for fixation, there is no need to modify the main structure of the UAV, which reduces the difficulty and cost of modification, while ensuring the firmness of the connection between the observation frame and the airframe.

[0025] Please see Figure 2-5 A further solution based on this embodiment is as follows: a connecting cylinder 11 is provided on the frame plate 1. The connecting cylinder 11 can be interference-fitted into the mounting hole 51. The connecting cylinder 11 has threads corresponding to the screws. The height of the UAV landing gear 5 is greater than the height of the connecting cylinder 11. The connecting bolt 12 can press against the surface of the UAV landing gear 5. The connecting cylinder 11 is inserted into the mounting hole 51 with an interference fit, and the landing gear surface is pressed from above by the connecting bolt 12, forming a dual fixing method of "embedded + top pressing", which significantly improves the vibration resistance and shear resistance of the connection part and effectively prevents loosening or falling off due to vibration during flight.

[0026] Working Principle: First, the infrared thermal imager or visible light camera is installed in the assembly component 3 on the turntable 21. The housing of the infrared thermal imager or visible light camera is usually rectangular or approximately rectangular, with slots on both sides that match the spring clips 32. These slots are concave openings along the length of the equipment housing, and their positions and dimensions are designed according to the spacing of the L-shaped blocks 31 in the assembly component 3 and the extension height of the spring clips 32. In practical applications, the housing of this type of observation equipment is customized by the equipment manufacturer according to the structure of the assembly component 3 of this observation frame to ensure that the slots and spring clips 32 can reliably cooperate. During installation, the operator pushes the equipment between the two symmetrically arranged L-shaped blocks 31. The spring clips 32 are elastically deformed by the pressure of the housing sidewalls. When the equipment continues to move down to the slot position, the spring clips 32 spring back and embed into the slots, achieving quick locking. For disassembly, simply pull it out to remove it from the slots and the equipment can be removed. After the equipment installation is completed, the motor 43 is controlled to rotate in both directions, which drives the screw 42 to rotate. This causes the nut seat 451 and the rack 45 to move linearly along the dovetail block 44, thereby driving the gear 22 and the turntable 21 fixed to it to rotate, thus adjusting the orientation of the observation equipment to meet the inspection angle requirements of different power facilities.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
