Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) equipment technology, and more specifically, to a multi-functional extension connection component for a UAV pod. Background Technology

[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.

[0003] In the daily operation of hydropower plants and photovoltaic power plants, routine inspections are crucial. Their core purpose is to monitor the operating status of equipment and facilities in real time, promptly identify potential defects, safety hazards, or performance degradation trends, such as equipment overheating, mechanical loosening, insulation damage, or vegetation obstruction. Regular inspections can effectively prevent sudden equipment failures, reduce the risk of unplanned outages, ensure the continuity and stability of power production, and provide a basis for decision-making on preventive maintenance of equipment. They are a fundamental and key link in ensuring the safe and efficient operation of power plants.

[0004] With technological advancements, drone inspections have become widely used in such scenarios. Based on the power plant layout, drones automatically fly along designated routes. Subsequently, the drones, equipped with visible light and infrared detection pods, take off autonomously and fly along the predetermined routes. During flight, the pods take multi-angle high-definition photos and perform infrared thermal imaging scans of components, lines, and facilities, transmitting the data back to the ground station in real time. Professionals then analyze the massive amounts of images and data to accurately identify anomalies, such as hot spots on photovoltaic panels or cracks in hydraulic structures, thereby achieving efficient and non-contact diagnosis.

[0005] However, the aforementioned technologies have the following drawbacks: the existing pods have limited functionality, which severely restricts the flexibility of inspections. They cannot quickly switch sensors according to mission requirements, making it difficult to cope with complex or new inspection items, resulting in low efficiency and increased costs. To complete different inspection targets, it is necessary to frequently take off and land to change equipment or deploy multiple drones. Utility Model Content

[0006] To address the aforementioned technical problems, the purpose of this utility model is to provide a multi-functional extended connection component for drone pods, which can improve inspection efficiency and reduce the number of drone takeoffs and landings.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A multi-functional extension connection component for a drone pod includes a body, a connecting frame at the bottom of the body, a support frame on the connecting frame, a storage slot on the support frame, an opening on one side of the storage slot, a baffle on the support frame for closing the opening on one side of the storage slot, a detachable connection between the support frame and the connecting frame, and a limiting member on the connecting frame for limiting the position of the support frame on the connecting frame.

[0009] In some possible embodiments, the bottom of the connecting frame is provided with a horizontal groove, a slider is slidably disposed in the groove, one side of the groove is open, a connecting rod is fixedly disposed at the bottom of the slider, the connecting rod is fixedly connected to the support frame, and the limiting member is used to limit the position of the slider in the groove.

[0010] In some possible embodiments, the limiting member is set as a limiting pin, the side wall of the connecting frame is provided with an installation hole along the direction perpendicular to the length of the slide groove, the installation hole is connected to the slide groove, the limiting member is slidably inserted into the installation hole, the side wall of the slider is provided with a limiting hole for the limiting member to be inserted, and the connecting frame is provided with a first elastic member, the first elastic member is used to drive the limiting member to move toward the limiting hole.

[0011] In some possible embodiments, a frustum is fixedly provided at the end of the limiting member away from the connecting frame, the diameter of the frustum being larger than that of the limiting member, the first elastic member being configured as a tension spring, the first elastic member being sleeved on the limiting member, one end of the first elastic member being fixedly connected to the side wall of the frustum near the connecting frame, and the other end being fixedly connected to the side wall of the connecting frame.

[0012] In some possible embodiments, a locking key is fixedly provided on the peripheral wall of the limiting member along the length direction of the limiting member, and a locking groove is provided on the side wall of the connecting frame along the axial direction of the mounting hole. The locking key is slidably disposed in the locking groove. The length of the locking key is greater than the depth of the limiting hole. When the end of the locking key near the slider abuts against the side wall of the connecting frame, the limiting member is completely disengaged from the limiting hole.

[0013] In some possible embodiments, the top of the support frame is provided with an installation groove along the length of the slide, and an installation block is slidably disposed in the installation groove in the vertical direction. The top of the installation block is used to abut against the bottom of the connecting frame. A second elastic member is provided in the installation groove, and the second elastic member acts on the installation block to make the installation block have an upward movement tendency.

[0014] In some possible embodiments, the second elastic element is configured as a spring, one end of the second elastic element is fixedly connected to the inner bottom wall of the mounting groove, and the other end is fixedly connected to the bottom of the mounting block. Multiple second elastic elements are provided, and the multiple second elastic elements are evenly arranged along the length direction of the mounting groove.

[0015] In some possible embodiments, the top of the mounting block on the side away from the groove opening is configured as a slope, the slope being used for sliding connection with the connecting frame, and the slope being covered with a sliding layer.

[0016] In summary, the technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0017] 1. The detachable support frame and slide block mechanism enable quick assembly and disassembly of the pod. Operators only need to push the pod into the support frame along the slide block, and the limit piece will automatically lock it. This greatly shortens the downtime required for sensor switching, significantly improves the response speed and operational flexibility of the UAV in complex inspection tasks, effectively solves the problem of frequent take-off and landing caused by the single function of the pod, and thus improves the overall inspection efficiency.

[0018] 2. The first elastic element acts on the limiting element to ensure the connection stability of the pod during flight. Under the action of the tension spring, the limiting pin can be reliably inserted into the limiting hole of the slider, effectively preventing the support frame from accidentally slipping off during vibration or maneuvering flight, enhancing the safety of the suspension, reducing the risk of data acquisition failure or equipment crash due to equipment loosening, and ensuring the continuity and reliability of the inspection operation.

[0019] 3. The storage compartment provides excellent equipment compatibility and expandability. By removing the baffle, it provides excellent equipment compatibility and expandability, and can accommodate and fix detection equipment of different specifications, such as infrared thermal imagers and multispectral sensors, to achieve rapid adaptation of multi-functional pods. This allows multiple detection tasks to be completed in a single flight, and promotes the application of multi-source data fusion analysis technology.

[0020] 4. The buffer structure of the mounting block and the second elastic element effectively improves the stability of the connection and the life of the equipment. Multiple springs apply an upward force evenly, ensuring that the top of the mounting block is always in close contact with the bottom of the connecting frame, eliminating connection gaps. This not only absorbs vibration energy during flight and reduces the impact on precision sensors, but also reduces installation wear through the sliding layer, thereby reducing the long-term maintenance costs and usage risks of the equipment.

[0029] Reference Figure 2 and Figure 4 As one embodiment of this utility model, refer to Figure 2A guide groove 3 is vertically formed on one side of the connecting frame 11. A guide block 31 is slidably disposed within the guide groove 3. A baffle 14 is fixedly connected to the guide block 31. A magnetic block (not shown in the figure) is disposed within the guide groove 3. A magnetic component (not shown in the figure) is installed on the top of the guide block 31. The magnetic component and the magnetic block are magnetically attracted to each other. The magnetic connection between the magnetic component and the magnetic block is existing technology and will not be described in detail here. The storage slot 13 can be opened or closed by sliding the baffle 14, thereby allowing for quick replacement of the inspection instruments within the storage slot 13.

[0030] Reference Figure 2 and Figure 3 The bottom of the connecting frame 11 is provided with a horizontal groove 4, and a slider 41 is slidably arranged in the groove 4. One side of the groove 4 is open, and a connecting rod 42 is fixedly arranged at the bottom of the slider 41. The connecting rod 42 is fixedly connected to the support frame 12. The limiting member 2 is used to limit the position of the slider 41 in the groove 4.

[0031] As one embodiment of this utility model, refer to Figure 2 The slide 4 is a T-shaped groove, and the slider 41 is a T-shaped block that is adapted to the slide 4.

[0032] Reference Figure 2 and Figure 3 In one embodiment of this utility model, the limiting member 2 is set as a limiting pin. The side wall of the connecting frame 11 is provided with an installation hole 43 along the length direction perpendicular to the slide groove 4. The installation hole 43 is connected to the slide groove 4. The limiting member 2 is slidably inserted into the installation hole 43. The side wall of the slider 41 is provided with a limiting hole 44 for the limiting member 2 to be inserted. The connecting frame 11 is provided with a first elastic member 45. The first elastic member 45 is used to drive the limiting member 2 to move toward the limiting hole 44.

[0033] Reference Figure 3 A frustum 46 is fixedly provided at one end of the limiting member 2 away from the connecting frame 11. The diameter of the frustum 46 is larger than that of the limiting member 2. The first elastic member 45 is a tension spring. The first elastic member 45 is sleeved on the limiting member 2. One end of the first elastic member 45 is fixedly connected to the side wall of the frustum 46 near the connecting frame 11, and the other end is fixedly connected to the side wall of the connecting frame 11.

[0034] The first elastic element 45 acts on the limiting element 2, ensuring the connection stability of the pod during flight. Under the action of the tension spring, the limiting pin can be reliably inserted into the limiting hole 44 of the slider 41, effectively preventing the support frame 12 from accidentally slipping off during vibration or maneuvering flight, enhancing the safety of the suspension, reducing the risk of data acquisition failure or equipment crash due to equipment loosening, and ensuring the continuity and reliability of the inspection operation.

A locking groove 48 is provided on the side wall of the connecting frame 11 along the axial direction of the mounting hole 43. The locking key 47 is slidably disposed in the locking groove 48. The length of the locking key 47 is greater than the depth of the limiting hole 44. When the end of the locking key 47 near the slider 41 abuts against the side wall of the connecting frame 11, the limiting member 2 completely disengages from the limiting hole 44.

[0036] Reference Figure 2 and Figure 4 The top of the support frame 12 is provided with an installation groove 5 along the length of the slide groove 4. An installation block 51 is slidably arranged in the vertical direction in the installation groove 5. The top of the installation block 51 is used to abut against the bottom of the connecting frame 11. A second elastic member 52 is provided in the installation groove 5. The second elastic member 52 acts on the installation block 51 so that the installation block 51 has an upward movement tendency.

[0037] Reference Figure 4 As one embodiment of this utility model, the second elastic element 52 is configured as a spring. One end of the second elastic element 52 is fixedly connected to the inner bottom wall of the mounting groove 5, and the other end is fixedly connected to the bottom of the mounting block 51. Multiple second elastic elements 52 are provided, and the multiple second elastic elements 52 are evenly arranged along the length direction of the mounting groove 5.

[0038] Reference Figure 4 The top of the side of the mounting block 51 away from the opening of the slide groove 4 is set as an inclined surface 53. The inclined surface 53 is used to slide and connect with the connecting frame 11. A sliding layer is provided on the inclined surface 53. As one embodiment of this utility model, the material of the sliding layer is set as polytetrafluoroethylene.

[0039] During the installation of the support frame 12, the inclined surface 53 on the mounting block 51 first abuts against the connecting frame 11. As the support frame 12 moves, the mounting block 51 is gradually pressed into the mounting groove 5 under the squeezing action of the inclined surface 53. At this time, the second elastic element 52 generates elastic force by squeezing. In the above process, the setting of the inclined surface 53 facilitates the installation of the support frame 12. The setting of the sliding layer effectively reduces the sliding friction force received by the inclined surface 53 during the sliding process, further facilitating the installation and improving the installation efficiency.

[0040] The implementation principle of the multi-functional extended connection component for a drone pod proposed in this embodiment is as follows:

[0041] The detachable support frame 12 and the sliding block 41 mechanism of the slide 4 enable rapid disassembly and replacement of the pod. The operator only needs to push the pod into the support frame 12 along the slide 4, and the limiting part 2 will automatically lock it, which greatly shortens the downtime required for sensor switching and significantly improves the response speed and operational flexibility of the UAV in complex inspection tasks. It effectively solves the problem of frequent take-off and landing caused by the single function of the pod, thereby improving the overall inspection efficiency. The storage slot 13 provides good equipment compatibility and expansion capability. By removing the baffle 14, it provides good equipment compatibility and expansion capability, which can accommodate and fix detection equipment of different specifications, such as infrared thermal imagers and multispectral sensors, to achieve rapid adaptation of multi-functional pods. This allows multiple detection tasks to be completed in a single flight, promoting the application of multi-source data fusion analysis technology.
