Description

Technical Field

[0002] In the field of power distribution network inspection, the traditional manual inspection model has significant limitations. Not only is manual inspection inefficient, but it also becomes exponentially more difficult in complex terrain like mountainous areas and jungles, and in adverse weather conditions like heavy rain, strong winds, ice and snow. Operators also face multiple safety risks, such as electric shock and falls from heights. This traditional inspection method cannot meet the stringent requirements of modern power systems for timely, accurate, and comprehensive inspections.

[0035] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0036] See also Figures 1 to 5 As shown, according to an embodiment of the present application, a power distribution network inspection device is provided, comprising a drone body 1, a positioning box 2 and an onboard analysis box 3; a positioning groove 11 is provided on the upper surface of the drone body 1; the positioning box 2 is detachably embedded in the positioning groove 11, and the top of the positioning box 2 protrudes from the notch plane of the positioning groove 11; the onboard analysis box 3 is buckled on the top of the positioning box 2, and the bottom of the onboard analysis box 3 is provided with a receiving groove 31 adapted to the top of the positioning box 2, the inner side wall of the receiving groove 31 is provided with at least a pair of snap-fitting grooves 311, and the outer side wall of the receiving groove 31 is provided with a plurality of snap-fitting grooves 311. At least one pair of spring grooves 312 are provided, and the spring grooves 312 are arranged opposite to the snap-fit ​​grooves 311. A pressing spring structure 32 is provided in the spring grooves 312. The driving end of the pressing spring structure 32 passes through the side wall of the accommodating groove 31 and is connected to the snap-fit ​​groove 311. A retractable protrusion 21 is provided at a position of the outer wall of the positioning box 2 relative to the snap-fit ​​groove 311. The retractable protrusion 21 is used to be embedded in the snap-fit ​​groove 311 when installing the on-board analysis box 3. The pressing spring structure 32 is used to drive the retractable protrusion 21 to withdraw from the snap-fit ​​groove 311 when disassembling the on-board analysis box 3.

[0037] In this embodiment, through the cooperation between the positioning box 2 and the positioning groove 11, as well as the snap-fit ​​groove 311, the spring groove 312 and the pressing spring structure 32 in the accommodating groove 31 of the on-board analysis box 3, and the design of the retractable protrusion 21 on the positioning box 2, the installation of the on-board analysis box 3 can be completed by simply buckling it onto the positioning box 2, and the protrusion 21 automatically embeds into the snap-fit ​​groove 311; when disassembling, the spring structure 32 is pressed to drive the protrusion 21 out of the snap-fit ​​groove 311, so that the on-board analysis box 3 can be easily removed without the need for complicated tools and tedious operations, thereby greatly improving the efficiency of installation and disassembly.

[0038] The drone body 1 serves as a carrier, and a positioning groove 11 is provided on its upper surface for determining the installation position of the positioning box 2 .

[0039] The positioning box 2 is removably inserted into the positioning slot 11, with its top protruding from the slot plane to form an interface with the onboard analysis box 3. At the same time, the outer wall of the positioning box 2 is provided with a retractable protrusion 21 (such as a spring pin or elastic buckle) for engaging with the onboard analysis box 3.

[0040] The bottom of the onboard analysis box 3 defines a receiving slot 31, whose shape matches the top of the positioning box 2, ensuring a precise fit. The inner wall of the receiving slot 31 defines a snap-fitting slot 311 (e.g., a groove or slot), while the outer wall defines a corresponding spring slot 312. A pressing spring structure 32 (e.g., a push-button spring lock) is mounted within the spring slot 312. Its driving end (e.g., a push rod) extends through the side wall of the receiving slot 31 and communicates with the snap-fitting slot 311.

[0041] It is understood that during installation, the positioning box 2 is first inserted into the positioning slot 11 of the drone body 1 to complete the initial fixation; then the receiving slot 31 of the airborne analysis box 3 is aligned with the top of the positioning box 2 and snapped downward; finally, the protrusion 21 of the positioning box 2 is squeezed and contracted during the snapping process (e.g., through a bevel design) until it reaches the position of the snap-in slot 311 and pops out, snapping into the snap-in slot 311 to achieve locking. During disassembly, the button on the outside of the spring slot 312 is first pressed to drive the push rod of the spring structure 32 to move toward the snap-in slot 311; then the push rod pushes the protrusion 21 back (e.g., compresses the spring), causing it to disengage from the snap-in slot 311; finally, the airborne analysis box 3 is lifted upward to complete disassembly.

[0042] In some possible implementations disclosed in this application, see Figure 2 As shown, the inner wall of the positioning groove 11 is provided with at least a pair of insertion holes, and the outer wall of the positioning box 2 is provided with a retractable insertion rod 22 at a position relative to the insertion holes. The retractable insertion rod 22 is used to be embedded in the insertion holes when the positioning box 2 is installed.

[0043] In this embodiment, the retractable rod 22 cooperates with the socket to ensure that the positioning box 2 remains stable after being installed in place, and will not change position due to factors such as vibration of the drone during flight, thereby improving the stability and reliability of the entire power distribution network inspection device.

[0044] The positioning groove 11 is formed on the upper surface of the drone body 1, and its inner side wall is provided with at least one pair of sockets. These sockets are part of the positioning groove 11 and are used to cooperate with corresponding structures on the positioning box 2 to play a role in positioning and fixing.

[0045] The positioning box 2 is a component that is detachably embedded in the positioning groove 11, and its outer wall is provided with retractable insertion rods 22 at the position relative to the insertion hole of the positioning groove 11. These insertion rods 22 are part of the positioning box 2, and their retractable function is the key to achieve cooperation with the positioning groove 11.

[0046] It will be appreciated that when installing the positioning box 2, it is inserted into the positioning slot 11. At this point, the retractable rod 22 on the positioning box 2 will correspond to the socket on the inner wall of the positioning slot 11. Because the rod 22 is retractable, it automatically extends and inserts into the socket during insertion, allowing the positioning box 2 to be accurately installed in the positioning slot 11. Furthermore, the way the rod 22 inserts into the socket prevents the positioning box 2 from shifting or shaking within the positioning slot 11, thereby improving the stability and reliability of the entire power distribution network inspection device.

[0047] In some possible implementations disclosed in this application, see Figure 3 As shown, a partition 23 is provided in the positioning box 2, and a first spring 24 is provided on both sides of the partition 23. A slide 25 is connected to the end of each first spring 24 away from the partition 23. The slide 25 is fixedly connected to the insertion rod 22 and the protrusion 21 respectively. The side walls of the positioning box 2 are respectively provided with clearance holes relative to the positions of the protrusion 21 and the insertion rod 22. The protrusion 21 and the insertion rod 22 are used to pass through the corresponding clearance holes respectively and can slide in the clearance holes.

[0048] In this embodiment, the first spring 24 stores energy when compressed by an external force and releases the energy when the external force disappears, returning the slide 25, the rod 22, and the bump 21 to their initial positions, thus achieving the telescopic function of the rod 22 and the bump 21. This not only facilitates the installation and removal of the positioning box 2 from the drone body 1 and the onboard analysis box 3, but also provides a certain buffering effect when the device is subjected to vibration or other external forces, protecting various components from damage, thereby improving the stability and reliability of the entire power distribution network inspection device.

[0049] Among them, the interior of the positioning box 2 is provided with a partition 23, which can separate the interior of the positioning box 2 into two relatively independent spaces. The partition 23 plays the role of support and separation, providing a stable infrastructure for the installation and operation of subsequent components.

[0050] First springs 24 are mounted on either side of the partition 23. These springs 24 are elastic and can deform under external force, storing elastic potential energy. They then return to their original shape and release the energy when the force is removed. These first springs 24 are the core components that enable the extension and retraction of the rod 22 and the bump 21. One end of each spring is fixedly connected to the partition 23, providing a support point for the deformation of the first springs 24.

[0051] Each first spring 24 is connected to a slide 25 at one end away from the partition 23. The slide 25 acts as a force transmitter and connector. Driven by the springs, the slides 25 are connected to the first springs 24 and can slide within the positioning box 2. Furthermore, the slides 25 are fixedly connected to the rod 22 and the bump 21, respectively, transmitting the spring's expansion and contraction force to the rod 22 and the bump 21, allowing them to expand and contract with the movement of the slides 25.

[0052] The sidewalls of the positioning box 2 are provided with clearance holes corresponding to the positions of the protrusions 21 and the insertion rods 22. These clearance holes provide space for the extension and retraction of the protrusions 21 and the insertion rods 22, allowing them to pass through and slide freely within their corresponding clearance holes. This design ensures that the protrusions 21 and the insertion rods 22 can extend from the positioning box 2 to engage with external components (such as the positioning slots 11 of the drone body 1 and the engaging slots 311 of the onboard analysis box 3) for securement, while also allowing them to retract into the positioning box 2 when needed, facilitating disassembly and installation.

[0053] It is understood that by providing the spacer 23, first spring 24, and slide plate 25 within the positioning box 2, and utilizing the elastic force of the first spring 24, when one component (such as the bump 21 or the insertion rod 22) is subjected to an external force, the slide plate 25 and the first spring 24 can drive the other component to move synchronously. For example, when installing the positioning box 2, pressing the bump 21 can cause the insertion rod 22 to be simultaneously squeezed and retracted, facilitating the insertion and withdrawal of the insertion rod 22 from the receptacle, thereby enabling quick installation and removal of the positioning box 2 from the drone body 1.

[0054] In some possible implementations disclosed in this application, see Figure 3 As shown, the protrusion 21 extends toward the engaging groove 311 , and the insertion rod 22 extends toward the insertion hole. The extension length of the protrusion 21 is smaller than the extension length of the insertion rod 22 .

[0055] In this embodiment, because the extended length of the projection 21 is shorter than the extended length of the insertion rod 22, when the onboard analysis cartridge 3 is removed, the spring structure 32 is pressed to retract the projection 21, allowing the onboard analysis cartridge 3 to separate from the positioning cartridge 2. At this time, the insertion rod 22, while still extending longer, can still be securely inserted into the insertion hole of the positioning slot 11 of the drone body 1, thereby ensuring that the positioning cartridge 2 remains stably fixed to the drone body 1 during the removal process of the onboard analysis cartridge 3, and preventing the positioning cartridge 2 from loosening or shifting due to the external force generated by the removal of the onboard analysis cartridge 3.

[0056] In the power distribution network inspection device, the positioning box 2 and the onboard analysis box 3 are connected by a protrusion 21 and a snap-in groove 311. The protrusion 21 is provided on the outer wall of the positioning box 2, and its extension direction is toward the snap-in groove 311 on the inner wall of the bottom accommodating groove 31 of the onboard analysis box 3. When the onboard analysis box 3 is installed, the protrusion 21 on the positioning box 2 will align with and embed into the snap-in groove 311 during the snap-in process, thereby achieving a fixed connection between the positioning box 2 and the onboard analysis box 3. For example, when the onboard analysis box 3 is snapped downward onto the positioning box 2, the protrusion 21 will gradually approach and insert into the snap-in groove 311, thereby fixing the onboard analysis box 3.

[0057] The positioning box 2 is connected to the drone body 1 via a rod 22 and a socket. The rod 22 is located on the outer wall of the positioning box 2 and extends toward the socket on the inner wall of the positioning slot 11 on the drone body 1. During installation of the positioning box 2, the rod 22 aligns with the socket and inserts as the positioning box 2 is inserted, stably securing the positioning box 2 within the positioning slot 11 of the drone body 1. For example, when the positioning box 2 is inserted into the positioning slot 11 of the drone body 1, the rod 22 automatically extends and inserts into the socket, preventing the positioning box 2 from shifting or shaking within the positioning slot 11.

[0058] It is understood that the extension length of the protrusion 21 is less than the extension length of the insertion rod 22, which means that the length of the protrusion 21 extending from the side wall of the positioning box 2 is less than the length of the insertion rod 22 extending from the side wall of the positioning box 2. When the onboard analysis box 3 is disassembled, the pressing spring structure 32 drives the protrusion 21 to retract, allowing the onboard analysis box 3 to be separated from the positioning box 2. Due to the long extension length of the insertion rod 22, it can still be firmly embedded in the socket of the positioning groove 11 of the drone body 1, ensuring that the positioning box 2 will not loosen or shift due to the external force generated by the disassembly of the onboard analysis box 3 during the disassembly process of the onboard analysis box 3. For example, when the onboard analysis box 3 is disassembled, the protrusion 21 retracts into the positioning box 2 under the action of the pressing spring structure 32, while the insertion rod 22 remains firmly inserted into the socket of the drone body 1, ensuring the stability of the connection between the positioning box 2 and the drone body 1 and preventing the positioning box 2 from falling off the drone body 1. As a result, the positioning box 2 and the onboard analysis box 3 can be disassembled step by step. When disassembling, first press the button on the outside of the spring slot 312 to drive the push rod of the pressing spring structure 32 to move toward the snap-in slot 311. The push rod pushes the protrusion 21 to retract, so that it disengages from the snap-in slot 311. At this time, the on-board analysis box 3 can be lifted upward to complete the separation from the positioning box 2; and because the extension length of the protrusion 21 is less than the insertion rod 22, the insertion rod 22 is still firmly embedded in the jack of the positioning slot 11 of the drone body 1, and the positioning box 2 still maintains a fixed connection with the drone body 1. If the positioning box 2 needs to be disassembled, it can be operated separately, thereby realizing the step-by-step disassembly of the positioning box 2 and the on-board analysis box 3, avoiding the inconvenience caused by disassembling the two at the same time, and reducing the risk of the positioning box 2 accidentally falling off from the drone body 1 due to misoperation.

[0059] In some possible implementations disclosed in this application, see Figure 3 As shown, guide rods 26 are respectively provided on both sides of the partition 23. The guide rods 26 extend in the same direction as the protrusion 21 and the insertion rod 22. A guide hole is opened on the slide plate 25. The guide rods 26 are inserted into the guide hole, and the slide plate 25 can slide along the extension direction of the guide rods 26.

[0060] In this embodiment, the guide rod 26 cooperates with the guide hole on the skateboard 25, providing precise guidance for the sliding of the skateboard 25, so that when the skateboard 25 slides along the extension direction of the guide rod 26, it can only move in the straight line direction defined by the guide rod 26, effectively preventing the skateboard 25 from shaking, deflecting or rotating during movement, and ensuring that the protrusion 21 and the insertion rod 22 fixedly connected to the skateboard 25 can be accurately extended or retracted, thereby improving their accuracy in cooperation with the jack of the positioning slot 11 and the snap-in slot 311 of the on-board analysis box 3, thereby enhancing the stability and reliability of the connection of the entire power distribution network inspection device.

[0061] Guide rods 26 are provided on both sides of the partition 23. These guide rods 26 extend in the same direction as the protrusions 21 and the insertion rods 22. Their function is to provide a fixed direction for the movement of the slide 25, ensuring that the slide 25 maintains a stable trajectory during movement without shaking or deflection, thereby ensuring that the protrusions 21 and the insertion rods 22 can be accurately extended and retracted and cooperate with corresponding components (such as the engaging grooves 311 and the insertion holes).

[0062] The slide 25 is provided with guide holes through which the guide rods 26 pass. This design creates a sliding connection between the slide 25 and the guide rods 26. When an external force acts on the slide 25 (e.g., due to the expansion and contraction of the first spring 24), it can slide along the extension direction of the guide rods 26. The combination of the guide holes and the guide rods 26 restricts the movement of the slide 25 to a specific direction, improving the accuracy and reliability of the movement of the entire mechanism, ensuring the stability and precision of the protrusion 21 and the insertion rod 22 during the expansion and contraction process, and thereby ensuring the stability and reliability of the connection between the positioning box 2, the drone body 1, and the onboard analysis box 3.

[0063] In some possible implementations disclosed in this application, see Figure 4 and Figure 5 As shown, the power distribution network inspection device also includes a positioning frame 4, which is screwed to the onboard analysis box 3. The positioning frame 4 is used to pass through the bottom wall of the onboard analysis box 3 and the top wall of the positioning box 2, and is embedded in the top of the slide 25 to fix the position of the slide 25 in the positioning box 2 when the power distribution network inspection device is working.

[0064] In this embodiment, by setting a positioning frame 4 that passes through the bottom wall of the onboard analysis box 3, the top wall of the positioning box 2 and is embedded in the top of the slide 25, the position of the slide 25 in the positioning box 2 can be accurately fixed when the power distribution network inspection device is working, ensuring that the slide 25 will not move or shake at will, thereby ensuring the stability and reliability of the entire device, which is conducive to improving the working precision and accuracy of the power distribution network inspection device.

[0065] The positioning frame 4 includes a frame body 41, which serves as the main body of the positioning frame 4 and has a roughly U-shaped structure. Its function is to connect the onboard analysis box 3 and the positioning box 2 and to position the slide 25. Specifically, the bottom end of the frame body 41, i.e., the lower end of the vertical sides of the frame body 41, can slide through the top of the onboard analysis box 3 and the top of the positioning box 2, and then insert into the top of the slide 25, thereby establishing a connection between the three. The positioning frame 4 can secure the position of the slide 25 within the positioning box 2.

[0066] The top of the onboard analysis box 3 is provided with a U-shaped groove that mates with the frame 41. A threaded rod 42 is rotatably mounted on the top of the frame 41, which mates with the threaded groove on the inner wall of the U-shaped groove. When the threaded rod 42 rotates, the threaded rod 42 causes the frame 41 to move up and down along the axial direction of the threaded rod 42, thereby tightening or loosening the connection between the positioning frame 4 and the analysis box.

[0067] Among them, the top of the threaded rod 42 is fixedly mounted with a rotating shaft 43, and the top of the rotating shaft 43 passes through the frame 41 and is fixedly mounted with a straight plate 45. By rotating the straight plate 45, the rotating shaft 43 and the threaded rod 42 can be driven to rotate together, making it convenient for the operator to adjust the position of the frame 41. At the same time, a limit ring 44 is fixedly mounted on the rotating shaft 43, and an annular groove matching the limit ring 44 is provided in the frame 41. The cooperation between the limit ring 44 and the annular groove can limit the axial movement of the rotating shaft 43, ensuring that the threaded rod 42 maintains a stable position during the rotation process, and enables the frame 41 to accurately connect or separate with the analysis box and the positioning box 2 when moving up and down, thereby ensuring the stability and reliability of the entire structure.

[0068] In some possible implementations disclosed in this application, see Figure 5 When the locking cam 321 is unlocked, the locking cam 322 is unlocked and the locking cam 323 is unlocked, so that the winch 310 can be unlocked. When the winch 310 is unlocked, the winch 310 can be unlocked.

[0069] In this embodiment, a pressure plate 321 is configured to move within the spring slot 312 and receive external pressure. The transmission rod 322 transmits the movement of the pressure plate 321 to the projection 21, allowing the projection 21 to retract when subjected to external pressure. This design allows the position of the projection 21 to be conveniently controlled by external pressure, enabling functions such as engaging or disengaging the positioning box 2 with other components. For example, when removing or installing the positioning box 2 or other components, the projection 21 can be retracted by pressing the pressure plate 321, thereby releasing the engaged state and facilitating operation. A second spring 323 provides a return force for the pressure plate 321 and transmission rod 322. When the external pressure disappears, the second spring 323 pushes the pressure plate 321 and transmission rod 322 back to their initial positions, thereby returning the projection 21 to its original position, achieving automatic resetting. This ensures that the structure returns to a stable initial state after each operation, facilitating the next use, thereby improving the reliability and ease of use of the device.

[0070] The pressure plate 321 is movably disposed within the spring slot 312, with its outer end surface extending to the opening of the spring slot 312. This design allows the pressure plate 321 to directly receive external pressure, and the externally applied force can be transmitted to the entire structure through the pressure plate 321. For example, when certain operations need to be performed on the device, such as releasing the locking connection between the positioning box 2 and other components, the pressure plate 321 can be pressed.

[0071] The transmission rod 322 is fixedly connected to the side of the pressure plate 321 facing the engaging groove 311 and moves synchronously with the pressure plate 321. Its function is to transmit the external pressure applied to the pressure plate 321 to the protrusion 21. The distal end of the transmission rod 322 penetrates the sidewall of the accommodating groove 311 and extends into the engaging groove 311, where it interlocks with the protrusion 21. When the pressure plate 321 moves in response to the pressure, the transmission rod 322 also moves, pushing the protrusion 21 back, separating the protrusion 21 from the engaging groove 311 and releasing the engagement.

[0072] Among them, at least two second springs 323 are provided, and at least two second springs 323 are respectively located on both sides of the transmission rod 322 and are arranged parallel to the transmission rod 322, respectively abutting the bottom of the spring groove 312 and the inner end surface of the pressure plate 321. When the pressure plate 321 is subjected to external pressure, the second spring 323 is compressed, storing elastic potential energy. When the external pressure disappears, the second spring 323 releases the elastic potential energy, pushing the pressure plate 321 and the transmission rod 322 to return to their initial positions, thereby causing the protrusion 21 to return to its original position, achieving automatic reset. In this way, the pressing spring structure 32 can return to a stable initial state after each operation, so as to facilitate the next use.

[0073] In some possible implementations disclosed in this application, see Figure 5As shown, the inner side wall of the spring groove 312 is provided with at least a pair of guide grooves, in which a slider 324 is slidably provided. The slider 324 is relatively fixed to the pressure plate 321 , and the slider 324 is used to cooperate with the guide groove to guide and limit the movement of the pressure plate 321 .

[0074] In this embodiment, the guide groove constrains the slider 324, so that the pressure plate 321 can only move linearly along the direction of the guide groove, avoiding the pressure plate 321 from tilting or offsetting when subjected to force, ensuring that the transmission rod 322 can accurately push the protrusion 21 to retract, and improving the operating accuracy of the pressing spring structure 32.

[0075] The inner side wall of the spring slot 312 is provided with at least one pair of guide slots, which extend along the moving direction of the pressing plate 321 and provide a sliding path for the slider 324 .

[0076] The slider 324 is fixed to the side of the pressing plate 321 and embedded in the guide groove. When the pressing plate 321 is subjected to external pressure, the slider 324 will slide in the guide groove, thereby limiting the movement of the pressing plate 321 to the direction specified by the guide groove.

[0077] It is understandable that the cooperation between the guide groove and the slider 324 ensures that the pressure plate 321 can only move in a straight line, preventing the pressure plate 321 from tilting or rotating when subjected to force. This allows the transmission rod 322 to accurately align with the protrusion 21 and effectively transmit the pressing force to the protrusion 21, ensuring that the protrusion 21 can retract as designed. At the same time, the length of the guide groove determines the maximum movement distance of the slider 324, thereby limiting the stroke of the pressure plate 321. When the slider 324 slides to the end of the guide groove, the pressure plate 321 can no longer move, which prevents structural damage caused by excessive pressure while ensuring that the protrusion 21 can be fully retracted but not over-retracted.

[0078] In some possible implementations disclosed in this application, see Figure 2 As shown, a sealing groove is provided at the bottom edge of the airborne analysis box 3 along the circumferential direction, and a circle of sealing gaskets 12 matching the sealing groove is provided on the upper surface of the drone body 1 relative to the sealing groove. The sealing gasket 12 is used to be embedded in the sealing groove when the airborne analysis box 3 is buckled on top of the positioning box 2.

[0079] In this embodiment, the sealing gasket 12 is embedded in the sealing groove, which can effectively prevent external water, dust, debris, etc. from entering the connection between the airborne analysis box 3 and the drone body 1, avoiding these substances from damaging the internal electronic components, improving the protection performance of the equipment, and ensuring the stable operation of the equipment under different environmental conditions.

[0080] A sealing groove is provided along the circumference of the bottom edge of the airborne analysis box 3. This groove is an annular groove that mates with the sealing gasket 12 to form a seal. Positioned at the bottom edge, it encircles the entire bottom of the airborne analysis box 3, ensuring a seal from all sides when connected to the drone body 1.

[0081] A sealing gasket 12 is provided on the upper surface of the drone body 1, corresponding to the sealing groove of the onboard analysis cartridge 3. The shape and size of the sealing gasket 12 match the sealing groove, allowing it to fit snugly within the groove. The sealing gasket 12 is typically made of a material with a certain degree of elasticity and sealing properties, such as rubber.

[0082] It is understood that when the onboard analysis box 3 is buckled onto the positioning box 2, that is, when the onboard analysis box 3 is installed on the drone body 1, the sealing gasket 12 will be accurately embedded in the sealing groove. This embedded fit allows the sealing gasket 12 to fit tightly against the inner wall of the sealing groove, thereby forming a closed space and preventing foreign matter from entering the connection between the onboard analysis box 3 and the drone body 1.

[0083] In some possible implementations disclosed in this application, see Figure 2 As shown, a plug 13 is provided on the upper surface of the drone body 1, and a socket is provided at a position of the onboard analysis box 3 relative to the plug 13. The socket is used to cooperate with the plug 13 to electrically connect the drone body 1 and the onboard analysis box 3 when the onboard analysis box 3 is buckled on the positioning box 2.

[0084] In this embodiment, the plug 13 on the drone body 1 cooperates with the socket on the onboard analysis box 3 to provide power to the onboard analysis box 3, enabling its normal operation. This ensures that the onboard analysis box 3 has a stable power supply during the drone's flight, ensuring that its various functions, such as data processing, analysis, and communication, can continue to operate stably. At the same time, a data transmission channel can be established between the drone body 1 and the onboard analysis box 3. This allows the onboard analysis box 3 to obtain information such as the drone's flight status and sensor data for analysis and processing, and can also transmit analysis results or other instructions to the drone body 1, enabling information exchange between the two, which helps to improve the overall performance and intelligence level of the drone.

[0085] A plug 13 is mounted on the top surface of the drone body 1. This plug 13 is an electrical connector that connects to the drone's internal circuitry and transmits power and data signals. Its placement on the top surface of the drone body 1 facilitates connection with the onboard analysis box 3. This position also ensures a relatively stable connection during flight, ensuring a reliable connection.

[0086] A socket is provided on the airborne analysis box 3 at a position corresponding to the plug 13 on the drone body 1. The socket is an electrical connection component that matches the plug 13. It has corresponding conductive structures and interfaces inside for docking with the pins of the plug 13. This ensures that when the airborne analysis box 3 is buckled onto the positioning box 2 in the prescribed manner, the socket can be accurately aligned with the plug 13 on the drone body 1.

[0087] It is understood that when the onboard analysis box 3 is buckled onto the positioning box 2, the plug 13 is inserted into the socket. The pins of the plug 13 make close contact with the conductive structure within the socket, thus establishing an electrical connection between the drone body 1 and the onboard analysis box 3. This connection ensures stable transmission of power and data signals between the two. During the insertion process, the plug 13 and the socket are equipped with a foolproof structure to ensure correct pin pairing and prevent connection failure due to reverse insertion or poor contact.
