Description

Technical Field

[0001] This application relates to the field of power equipment testing technology, and in particular to a testing device mounted on a drone. Background Technology

[0002] In recent years, unmanned and intelligent equipment, represented by drones, has been widely used in various industries. Utilizing mobile platforms such as drones, equipped with various sensors or tools, to replace or assist human labor in performing tasks in complex, dangerous, or inaccessible environments has become an important technological development trend. For example, in fields such as power line inspection, bridge detection, building surveying, and pipeline maintenance, drones equipped with inspection equipment can significantly improve operational efficiency and substantially reduce personnel safety risks.

[0003] However, effectively integrating detection equipment with mobile platforms such as drones, especially in scenarios requiring close contact or physical interaction between the detection equipment and the target, still faces significant challenges. During close-range operations, even minor operational errors or sudden environmental changes can easily lead to collisions between the sensor tip and the target object. Due to the lack of effective buffering mechanisms, the impact force from such collisions acts directly on the sensor and the drone without any attenuation. This not only easily damages the sensor but can also affect the drone's flight stability, potentially causing damage to the drone's structure or rotor, or even leading to serious safety accidents such as loss of control and crashes.

[0004] Furthermore, existing integrated solutions are often designed for specific UAV platforms and specific inspection tasks, resulting in rigid structures and a lack of modularity and scalability. This leads to not only high costs for the entire system, but also difficulty in porting it across different UAV platforms and in the ease of replacing different types of sensors according to task requirements, thus limiting its flexibility and versatility. Summary of the Invention

[0005] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a detection device mounted on a drone, which can improve the safety and operational reliability of the sensors and the drone itself.

[0006] The detection device carried by the UAV according to an embodiment of this application includes: an insulating rod, which is fixedly connected to the external UAV body; a detection mechanism, which is disposed at one end of the insulating rod and includes a sensor, which is movably connected to the insulating rod and is used to collect sensing signals; and a control mechanism, which is disposed on the insulating rod away from the detection mechanism and is electrically connected to the sensor, which is used to supply power and control the sensor, and to receive and process the sensing signals from the sensor. The movable seat assembly includes a base, a slider, a swing member, a first elastic member, and a second elastic member. The base is connected to the insulating rod. The slider is slidably connected to the base along the length of the insulating rod. The swing member is rotatably connected to the slider. The sensor is fixed to the first end of the swing member. A groove extending along the length of the insulating rod is provided on either the base or the slider, and a protrusion matching the groove is provided on the other. The protrusion is slidably received in the groove. The first elastic member is disposed within the groove, and its two ends abut against the groove wall and the side wall of the protrusion, respectively, to absorb axial impacts of the slider along the length of the insulating rod. The two ends of the second elastic member are connected to the second end of the swing member and the slider, respectively, to absorb lateral impacts received by the swing member.

[0007] The detection device mounted on a drone according to the embodiments of this application has at least the following beneficial effects: By integrating the detection mechanism and the control mechanism onto an independent insulating rod, a standardized functional module is formed, which can be easily mounted on different models of drones without complex modifications to the drone body, greatly expanding the applicability of the device. More importantly, the detection device mounted on the drone in the embodiments constructs a mechanical buffer mechanism by movably connecting the sensor to the insulating rod. When the drone operates in a complex environment, and its front-end detection mechanism inevitably collides with external objects, this movable connection structure can effectively absorb and dissipate the impact energy, playing a significant buffering role. This design not only effectively prevents the precision and expensive sensor from being damaged by rigid impact, but also prevents the impact force from being directly transmitted to the drone body through the insulating rod, thereby protecting both the sensor and the drone—two high-value components—simultaneously, significantly improving the reliability, safety, and service life of the entire system in practical applications.

[0008] According to some embodiments of this application, it also includes at least one support base connected to the insulating rod and having an installation interface for connecting to the drone body.

[0009] According to some embodiments of this application, the geometry of the swing member is adapted to the sensor, and the swing member has a receiving cavity adapted to the sensor, and the sensor is disposed in the receiving cavity.

[0010] According to some embodiments of this application, both the detection mechanism and the control mechanism are provided with a snap-fit ​​structure adapted to the insulating rod, so as to realize the detachable connection between the detection mechanism and the control mechanism and the insulating rod.

[0011] According to some embodiments of this application, the control mechanism includes a housing, and a controller and a power supply disposed within the housing; the housing includes a power supply box and a controller box that can be interlocked, the power supply being housed in the power supply box, and the controller being housed in the controller box.

[0027] like Figure 7 As shown, the detection device 600 carried by the UAV in this embodiment is an independent, modular system that can be easily installed on various commercial UAVs 500 for performing aerial detection tasks. It can be equipped with any type of sensor to adapt to different detection needs, such as current, temperature, and electromagnetic field strength.

[0028] like Figure 1 and Figure 2As shown, the detection device carried by the UAV in this embodiment includes an insulating rod 100, a detection mechanism 200 disposed at one end of the insulating rod 100, and a control mechanism 300 disposed away from the detection mechanism 200. The insulating rod 100 is the skeleton of the entire device, possessing sufficient mechanical strength and rigidity to support the various components mounted on it and maintain stability during flight. For example, the insulating rod 100 is preferably made of a lightweight, high-strength, non-conductive material, such as fiberglass or carbon fiber, which not only reduces the overall load but also ensures the safety of the device when in contact with live conductors (such as high-voltage lines). The interior of the insulating rod 100 may be hollow to allow wires or signal cables to pass through, resulting in a cleaner appearance of the device and protecting the cables from damage by the external environment. Optionally, the insulating rod 100 is securely connected to the external UAV body via one or more support bases 400.

[0029] Understandable, such as Figure 1 and Figure 2 As shown, the detection mechanism 200 is the core component for realizing the detection function. It is located at one end of the insulating rod 100 so that it can extend beyond the UAV body to easily approach and detect the target. The core of the detection mechanism 200 is a sensor (not shown in the figure). For example, this sensor could be a U-shaped fork-shaped current sensor (not shown in the figure) for non-contact measurement of current in a cable. Of course, depending on the application scenario, the sensor can also be other types and shapes of detection elements. Most importantly, in this embodiment, the sensor is not directly and rigidly fixed to the insulating rod 100, but is movably connected to it. This movable connection design provides a buffer mechanism for the detection device. When the UAV is in flight and the front detection mechanism 200 accidentally collides with an obstacle (such as a cable, utility pole, wall, etc.), this movable connection structure can absorb and disperse the impact force, thereby preventing the entire impact force from being transmitted to the sensor and the UAV body, effectively preventing damage to the precision sensor, and also ensuring the flight safety of the UAV.

[0030] Understandable, such as Figure 1 and Figure 2As shown, the control mechanism 300 is mounted on the insulating rod 100 and positioned away from the detection mechanism 200, for example, at the other end or middle of the insulating rod 100 near the center of gravity of the UAV. This layout balances the weight of the entire device, optimizes the payload distribution of the UAV, and improves flight stability. Furthermore, keeping the control mechanism 300, which contains the core circuitry, away from the high-risk collision zone at the front end also enhances its safety. The control mechanism 300 is electrically connected to the sensors in the detection mechanism 200 via wires. These wires can be housed inside the hollow insulating rod 100, as previously described. For example, the control mechanism 300 integrates a power supply (e.g., a battery) and a controller (e.g., a circuit board containing a microprocessor and a wireless communication module). It primarily performs two functions: first, providing a stable and reliable power supply to the front-end sensors; second, controlling the sensors (e.g., starting / stopping detection), receiving the raw sensor signals, performing preliminary processing and storage, and wirelessly transmitting the data to a ground control terminal or UAV remote controller for operator analysis and recording.

[0031] Understandable, such as Figure 3 and Figure 4 As shown, to achieve a "movable connection" between the sensor and the insulating rod 100, the detection mechanism 200 also includes a movable seat assembly 210. This movable seat assembly 210 is the core component for achieving the buffering function; it can be viewed as a mechanical unit with a fixed end and a movable end. Its fixed end is connected to the insulating rod 100, ensuring stable coupling with the main body of the device; while the sensor is mounted on its movable end, allowing the sensor to perform controlled, shock-absorbing movement relative to the insulating rod 100.

[0032] For example, in some embodiments, in order to achieve a multi-dimensional, multi-degree-of-freedom buffering effect, such as Figure 3 and Figure 4As shown, the movable seat assembly 210 further includes a base 211, a slider 212, and a swing member 213. These three components, when combined, form a two-stage buffer system. First, the base 211 is the stationary part of the movable seat assembly 210. For example, it is securely mounted on the insulating rod 100 via a snap-fit ​​structure 214 or other equivalent fastening method, providing a stable mounting reference for the entire movable seat assembly 210. Second, a sliding connection is formed between the slider 212 and the base 211. For example, the slider 212 can reciprocate along the length (i.e., axial direction) of the insulating rod 100 on the base 211. This design constitutes a first-stage buffer, primarily used to absorb and mitigate axial impacts from directly in front of the device. When the detection mechanism 200 collides head-on with an obstacle, the impact force first drives the sliding member 212 (along with the swing member 213 above it and the sensor) to slide backward along the insulating rod 100. This sliding process dissipates and disperses the impact energy, avoiding a rigid collision. Finally, the swing member 213 carries or directly integrates the sensor (not shown in the figure). The swing member 213 is rotatably connected to the sliding member 212 via a pivot or rotating shaft structure. This design constitutes a secondary buffer, allowing the swing member 213 (and the sensor) to swing or deflect relative to the sliding member 212 at a certain angle. This level of buffering is mainly used to absorb impact forces from the side or any non-axial angle. When the detection mechanism 200 suffers a lateral collision, the swing member 213 deflects, like a hinged door, further unloading and buffering the impact force through this rotational process.

[0033] In summary, by combining the translational motion of the "base 211-slider 212" and the rotational motion of the "slider 212-swinger 213," the movable seat assembly 210 of this embodiment constructs a composite buffer system with two degrees of freedom: translation and rotation. This system can effectively cope with collisions from different directions, providing comprehensive mechanical protection for the sensor and the UAV body, and greatly enhancing the reliability of the device in complex and unknown environments.

[0034] Understandable, such as Figure 5As shown, in some embodiments, to achieve a sliding connection between the slider 212 and the base 211 along the length of the insulating rod 100, a matching groove 211a and a protrusion 212a are provided between the base 211 and the slider 212. For example, a groove 211a is provided on the side of the base 211 facing the slider 212. The groove 211a runs parallel to the axis of the insulating rod 100, thus providing a guide for the linear movement of the slider 212. To ensure that the slider 212 remains coupled to the base 211 during movement and to prevent it from disengaging under lateral or bumpy forces, the cross-sectional profile of the groove 211a is preferably designed as a constraining shape, such as a T-groove or a dovetail groove. Accordingly, on the slider 212, a protrusion 212a that precisely matches the contour of the groove 211a is integrally formed or fixedly connected to its surface facing the base 211 (the protrusion 212a can be understood as the T-shaped or dovetail-shaped guide rail portion below the slider 212). The protrusion 212a is slidably received in the groove 211a, so that the slider 212 can only move along a single direction defined by the groove 211a (i.e., the axial direction of the insulating rod 100), while the degrees of freedom in other directions are completely restricted, ensuring the smoothness of the movement and the stability of the buffering process.

[0035] Of course, those skilled in the art will understand that the opposite configuration can also be used, that is, the groove 211a is set on the slider 212, and the matching protrusion 212a (or guide rail) is set on the base 211, which can also achieve the same sliding guide function. This application does not limit this.

[0036] Optional, such as Figure 5 As shown, in some embodiments, to facilitate efficient assembly of the slider 212 onto the base 211, one end of the groove 211a on the base 211 (e.g., the end furthest from the drone body) can be designed as an open structure. During assembly, the protrusion 212a of the slider 212 can be easily pushed into the groove 211a from the open end. After assembly, to prevent the slider 212 from slipping off the open end, a separate baffle can be installed to close the open end.

[0037] Furthermore, to control the relative sliding between the slider 212 and the base 211, in some embodiments, the movable seat assembly 210 is also provided with a first elastic element. For example, the first elastic element (e.g., a helical compression spring) is housed inside the groove 211a. One end abuts against the inner wall of the groove 211a (e.g., near the end of the drone body), and the other end abuts against the side wall of the protrusion 212a on the slider 212. Under normal operating conditions, the first elastic element is at its natural length or slightly pre-compressed, and its elastic force pushes the slider 212 to the foremost point of its travel, ensuring the sensor is in the predetermined detection position. When the detection mechanism 200 suffers a frontal collision along the length of the insulating rod, the external impact force forces the slider 212 to overcome the elastic force of the first elastic element and retract. In this process, the first elastic element is compressed, converting the kinetic energy of the impact into its own elastic potential energy, thereby absorbing and dissipating the axial impact energy and providing buffer protection. Once the external impact force disappears, the elastic potential energy stored in the first elastic element will be released immediately, pushing the slider 212 to automatically reset and return it to its initial working position without manual intervention, thus preparing it for the next impact.

[0038] Similarly, for cushioning lateral impacts, in some embodiments, a second elastic element is also provided between the swing member 213 and the sliding member 212. For example, such as... Figure 5 As shown, the oscillating member 213 rotates about its pivot point with the sliding member 212. Its first end (the end furthest from the pivot) is used to mount or integrate a sensor (not shown). On the other side of the pivot, a second end is provided, which can be understood as a lever arm for applying a reset torque. The two ends of a second elastic member (not shown, but could be, for example, a high-elasticity rubber ring or tension spring) are reliably connected to the second end of the oscillating member 213 and a fixed point on the sliding member 212, respectively. Under normal operating conditions, the second elastic member is slightly stretched, and the resulting tension applies a "centralized" torque to the oscillating member 213, keeping it upright and aligned with the axis of the insulating rod 100. When the sensor is subjected to a lateral impact, the oscillating member 213 deflects about the pivot, further stretching the second elastic member. The second elastic member absorbs the energy of the lateral impact during this stretching process. When the lateral impact force disappears, the stretched second elastic element will immediately retract, and the restoring torque it generates will drive the swinging element 213 to swing back to the initial center position quickly and accurately, thus achieving automatic lateral reset.

[0039] In summary, through the coordinated operation of the first and second elastic elements, the detection device carried by the UAV in this embodiment constructs a complete, automatically resettable passive buffer system that can cope with dual impact threats from the front and sides, thereby improving the reliability and environmental adaptability of the device.

[0040] Understandably, in some embodiments, in order to securely mount the detection device as a separate accessory to the drone body, the detection device carried by the drone in the embodiments also includes at least one support base 400. For example, as Figure 1 and Figure 5 As shown, the support base 400 has a channel or clamping structure for passing through and fixing the insulating rod 100, the inner diameter of which matches the outer diameter of the insulating rod 100. The support base 400 also has a standardized mounting interface for connecting to the UAV body. This mounting interface can be designed in various forms to adapt to different UAV platforms. For example, it can be a flat surface with standard threaded holes, allowing direct screw fixing to the UAV's pre-reserved mounting points; or it can be designed to be compatible with the bayonet or slide rail of mainstream UAV quick-release systems, enabling tool-free rapid assembly and disassembly. By setting up this independent support base 400, the entire testing device can be quickly mounted or disassembled as a complete unit, greatly improving the deployment efficiency of field operations. For longer or heavier insulating rods 100, two or more support bases 400 can be used for fixing to ensure the rigidity and stability of the installation and prevent vibration during flight.

[0041] Understandably, in some embodiments, the detection device carried by the UAV employs a highly modular design. For example, both the front-end detection mechanism 200 (specifically its base 211) and the rear-end control mechanism 300 are integrally formed or integrated with a snap-fit ​​structure 214 adapted to the insulating rod 100. For instance, as... Figure 5 and Figure 6As shown, the snap-fit ​​structure 214 is typically designed as a flexible, semi-enclosed snap-fit, or a clamp structure consisting of two or more parts fastened together by bolts. Its inner wall profile precisely matches the circular cross-section of the insulating rod 100, providing sufficient clamping force while facilitating easy installation, disassembly, or repositioning. The core advantage of this design lies in its detachable connection. Operators can easily snap the detection mechanism 200 and control mechanism 300 onto any desired position on the insulating rod 100. For example, the position of the control mechanism 300 can be fine-tuned according to the UAV's center of gravity to achieve optimal flight balance; or when not in use, each module can be easily removed from the insulating rod 100 for separate storage and maintenance, greatly facilitating transportation and maintenance. If a module (such as a sensor or controller) malfunctions, only the corresponding module needs to be replaced, without discarding the entire device, significantly reducing maintenance costs.

[0042] Understandably, in some embodiments, to achieve a secure connection between the sensor and the oscillating element 213, while also making the overall structure of the detection mechanism 200 more compact, the overall geometry of the oscillating element 213 may be designed to fit the outer contour of the sensor. Understandably, the oscillating element 213 is not a universal mounting bracket, but a component tailored to a specific sensor. For example, such as... Figure 1 and Figure 5 As shown, the interior of the swing component 213 is integrally molded or machined to form a receiving cavity 213a that precisely matches the shape of the sensor it is to support. In other words, the swing component 213 itself is like an "exoskeleton" or "protective shell" tailor-made for the sensor. During assembly, the sensor body (including its internal induction coil, circuit board, and other precision components) is completely and seamlessly placed within the receiving cavity 213a and finally fixed by adhesive, clips, or micro screws. The robust shell of the swing component 213 provides all-around enveloping protection for the relatively fragile sensor inside, effectively resisting the erosion of environmental factors such as scratches, dust, and moisture. In the event of a collision, it acts as the first line of defense, absorbing and dispersing impact forces to prevent stress from directly acting on the sensor body. At the same time, by combining the mechanical function of "swinging" with the load-bearing function of "accommodation," the number of parts is greatly simplified, the assembly complexity is reduced, and the manufacturing cost is lowered. The front end of the entire detection mechanism 200 looks more concise, compact, and professional.

[0043] Understandably, the control mechanism 300 is the energy center and intelligent core of the entire detection device, housed within a casing. For example, the control mechanism 300 integrates a separate power supply (e.g., a lightweight, high-capacity lithium battery) and a controller (e.g., a circuit board integrating a microprocessor and a wireless communication chip). The power module provides a stable and clean operating voltage to the sensors in the remote detection mechanism 200 via wires housed within the insulating rod 100, ensuring accurate measurements. The controller is responsible for sending commands to the sensors, such as starting detection, stopping detection, or adjusting parameters, and for receiving the raw sensing signals collected by the sensors in real time. Simultaneously, the controller performs necessary processing on the received signals, such as amplification, filtering, and digitization, and then wirelessly transmits the processed data to a ground operator's handheld terminal (e.g., a mobile app, tablet) or a drone remote controller via its built-in wireless communication unit (e.g., a Wi-Fi or Bluetooth module), enabling real-time data display and recording.

[0044] Understandably, this is to facilitate the inspection and disassembly of the control mechanism 300, such as Figure 6 As shown, in some embodiments, the housing consists of a power supply box 310 and a controller box 320. For example, the power supply box 310 creates a space for accommodating a power module (not shown, such as one or more batteries), and has an opening for easy battery access. The controller box 320 can be designed to match the opening of the power supply box 310. The controller box 320 directly serves as the cover of the power supply box 310, tightly covering the opening, and the two are reliably and removably secured by fasteners such as snap-fits or screws. This combines two functional components (the controller box 320 and the cover of the power supply box 310) into one, reducing the number of parts and making the entire control mechanism 300 more compact and lightweight. Furthermore, when it is necessary to replace or charge the batteries, the operator only needs to remove the controller housing, which acts as the "cover," to easily access the internal power module, making the entire process more convenient and faster. The power module provides a stable and clean operating voltage to the sensor in the remote detection mechanism 200 through wires housed inside the insulating rod 100, ensuring that it can perform accurate measurements.

[0045] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
