Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power equipment detection, and in particular to a detection device carried by a UAV. BACKGROUND

[0002] In recent years, unmanned and intelligent devices represented by UAVs have been widely used in various industries. Using mobile platforms such as UAVs to carry various sensors or tools to replace or assist human labor in performing tasks in complex, dangerous, or difficult-to-reach environments has become an important trend in technology development. For example, in the fields of power inspection, bridge detection, building survey, pipeline maintenance, etc., the detection device carried by the UAV can greatly improve the work efficiency and significantly reduce the safety risk of personnel.

[0003] However, effectively combining the detection device with the mobile platform such as the UAV, especially in scenarios where the detection device needs to be in close contact or physical interaction with the target to be detected, still faces serious challenges. In close-range operations, small errors in UAV operation or sudden environmental changes can easily cause the sensor front end to collide with the object to be detected. Due to the lack of effective buffer mechanism, the impact force generated by the collision will be applied to the sensor and the UAV body without attenuation. This not only easily damages the sensor, but also may affect the flight stability of the UAV, thereby causing damage to the structure or rotor of the UAV, and even causing serious safety accidents such as loss of control and crash.

[0004] In addition, some existing integration solutions are usually designed for specific UAV platforms and specific detection tasks, and their structures are fixed, lacking modularity and scalability. This results in not only high cost of the entire system, but also difficulty in porting between different UAV platforms, and inability to easily replace different types of sensors according to task requirements, limiting the flexibility and universality of its application. SUMMARY

[0005] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, the present application proposes a detection device carried by a UAV, which can improve the safety and operation reliability of the sensor and the UAV body.

[0006] According to the detection device carried by the drone of the embodiment of the present application, it includes: an insulating rod, which is fixedly connected to the external drone body; a detection mechanism, which is arranged at one end of the insulating rod, and the detection mechanism includes a sensor, which is movably connected to the insulating rod, and the sensor is used to collect sensing signals; a control mechanism, which is arranged on the insulating rod away from the detection mechanism, and the control mechanism is electrically connected to the sensor, and the control mechanism is used to power and control the sensor, and receive and process the sensing signals of the sensor. wherein the movable seat assembly includes a base, a sliding member, a swinging member, a first elastic member and a second elastic member, the base is connected to the insulating rod, the sliding member is slidably connected to the base along the length direction of the insulating rod, the swinging member is rotatably connected to the sliding member, and the sensor is fixed to the first end of the swinging member; a sliding groove extending along the length direction of the insulating rod is provided on either the base or the sliding member, and a protrusion matching the sliding groove is provided on the other, and the protrusion can be slidably received in the sliding groove; the first elastic member is arranged in the sliding groove and its two ends respectively abut against the groove wall of the sliding groove and the side wall of the protrusion, for absorbing the axial impact of the sliding member along the length direction of the insulating rod; the two ends of the second elastic member are respectively connected to the second end of the swinging member and the sliding member, for absorbing the lateral impact suffered by the swinging member.

[0007] The detection device carried by the drone according to the embodiment of the present application has at least the following beneficial effects: by integrating the detection mechanism and the control mechanism on an independent insulating rod, a standardized functional module is formed, which can be conveniently carried on drones of different models without the need for complex modifications to the drone body, greatly broadening the scope of application of the device. More importantly, the detection device carried by the drone of the embodiment constructs a mechanical buffer mechanism by movably connecting the sensor to the insulating rod. When the drone is operating in a complex environment, when the detection mechanism at its front end inevitably collides with external objects, the movable connection structure can effectively absorb and dissipate the impact energy, playing a significant buffering role. This design can not only effectively prevent the delicate and expensive sensors from being damaged by rigid impact, but also prevent 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, and significantly improving the reliability, safety and service life of the entire system in practical applications.

[0008] According to some embodiments of the present application, at least one supporting base is further included, wherein the supporting base is connected to the insulating rod and is provided with a mounting interface for connecting to the drone body.

[0009] According to some embodiments of the present application, the geometry of the swing member is adapted to the sensor, and the swing member is provided with a receiving cavity adapted to the sensor, and the sensor is arranged in the receiving cavity.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0017] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0018] In the description of this application, reference to the terms "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of this application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.

[0019] like Figure 7 As shown in the example, the drone-mounted detection device 600 is a standalone, modular system that can be easily installed on various commercial drones 500 to perform aerial inspection tasks. It can be equipped with any type of sensor to meet different detection needs, such as current, temperature, and electromagnetic field strength.

[0020] like Figure 1 and Figure 2As shown, the detection device carried by the embodiment unmanned aerial vehicle includes an insulating rod 100, a detection mechanism 200 arranged at one end of the insulating rod 100, and a control mechanism 300 arranged away from the detection mechanism 200. The insulating rod 100 is the skeleton of the entire device, which has sufficient mechanical strength and rigidity to carry various components mounted thereon and maintain stability during flight. In the example, the insulating rod 100 is preferably made of lightweight and high-strength non-conductive material, such as glass fiber or carbon fiber, which not only reduces the overall load but also ensures the safety of the device when contacting a live body (such as a high-voltage line). The inside of the insulating rod 100 can be hollow to facilitate the passage of wires or signal cables therethrough, making the appearance of the device more neat and protecting the cables from external environmental damage. Optionally, the insulating rod 100 is stably connected to the external unmanned aerial vehicle body through one or more support bases 400.

[0021] As can be understood, Figure 1 and Figure 2 As shown, the detection mechanism 200 is the core part that realizes the detection function, which is arranged at one end of the insulating rod 100 so as to be able to extend out of the unmanned aerial vehicle body and conveniently access and detect the target to be detected. The core of the detection mechanism 200 is a sensor (not shown in the figure), which can be a U-shaped fork current sensor (not shown in the figure) for non-contact measurement of current in the cable. Of course, according to different application scenarios, the sensor can also be other types and shapes of detection elements. Most importantly, the embodiment sensor is not directly and rigidly fixed on the insulating rod 100, but is movably connected with the insulating rod 100. This movable connection design provides a buffer mechanism for the detection device. When the detection mechanism 200 at the front end of the unmanned aerial vehicle collides with an obstacle (such as a cable, a power pole, a wall, etc.) during flight, the movable connection structure can absorb and disperse the impact force, thereby avoiding transmitting the entire impact force to the sensor and the unmanned aerial vehicle body, effectively preventing damage to the precision sensor and also ensuring the flight safety of the unmanned aerial vehicle.

[0022] As can be understood, Figure 1 and Figure 2As shown, the control mechanism 300 is mounted on the insulating rod 100, away from the detection mechanism 200, for example, at the other end or in the middle of the insulating rod 100, near the center of gravity of the drone. This layout balances the weight of the entire device, optimizing the drone's load distribution and improving flight stability. Furthermore, by placing the control mechanism 300, which contains the core circuitry, away from the front-end collision risk zone, it also enhances its own safety. The control mechanism 300 is electrically connected to the sensors in the detection mechanism 200 via wires. As previously mentioned, these wires can be housed within the hollow insulating rod 100. 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 stable and reliable power to the front-end sensors; and second, controlling the sensors (e.g., starting and stopping detection). It also receives raw sensing signals from the sensors, performs preliminary processing and storage, and wirelessly transmits the data to a ground control terminal or drone remote controller for analysis and recording by the operator.

[0023] 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 is further provided with a movable seat assembly 210. This movable seat assembly 210 is the core of the buffering function and can be considered as a mechanical unit with a fixed end and a movable end. The fixed end is connected to the insulating rod 100, ensuring a stable coupling with the device body; the sensor is mounted on the movable end, enabling controlled, impact-absorbing movement relative to the insulating rod 100.

[0024] For example, in some embodiments, in order to achieve a multi-dimensional, multi-freedom buffering effect, such as Figure 3 and Figure 4As shown, the movable seat assembly 210 is further comprised of a base 211, a sliding member 212 and a swinging member 213. These three components, in combination, form a two-stage buffer system. First, the base 211 is the stationary part in the movable seat assembly 210. In the example, it is firmly mounted on the insulating rod 100 via a clamping structure 214 or other equivalent fastening means. The base 211 provides a stable mounting reference for the entire movable seat assembly 210. Second, the sliding member 212 forms a sliding connection with the base 211. In the example, the sliding member 212 is capable of reciprocating along the length of the insulating rod 100 (i.e. axially) on the base 211. This design constitutes a first-stage buffer, mainly for absorbing and mitigating axial impact from the front of the device. When the detection mechanism 200 collides head-on with an obstacle, the impact force will first drive the sliding member 212 (together with the swinging member 213 and the sensor above it) to slide backward along the insulating rod 100. This sliding process dissipates and disperses the impact energy, avoiding rigid collision. Finally, the swinging member 213 carries or directly integrates the sensor (not shown in the figure). The swinging member 213 is rotationally connected to the sliding member 212 via a pivot or hinge structure. This design constitutes a second-stage buffer, which allows the swinging member 213 (and the sensor) to swing or deflect at an angle relative to the sliding member 212. This stage of buffer is mainly for absorbing impact from the side or any non-axial angle. When the detection mechanism 200 is subjected to a lateral collision, the swinging member 213 will deflect. Like a hinged door, this rotational process further unloads and buffers the impact force.

[0025] In summary, through the combination of translation of the "base 211-sliding member 212" and rotation of the "sliding member 212-swinging member 213", the example movable seat assembly 210 constructs a composite buffer system with two degrees of freedom of translation and rotation. This system can effectively deal with collisions from different directions, providing full-range mechanical protection for the sensor and the UAV body, greatly enhancing the reliability of the device in complex and unknown environments.

[0026] It can be understood that, as Figure 5As shown, in some embodiments, in order to achieve the sliding connection between the sliding member 212 and the base 211 along the length direction of the insulating rod 100, a matching sliding groove 211a and a protrusion 212a are arranged between the base 211 and the sliding member 212. For example, a sliding groove 211a is formed on the side of the base 211 facing the sliding member 212. The sliding groove 211a is parallel to the axis of the insulating rod 100, thereby providing a guide rail for the linear motion of the sliding member 212. In order to ensure that the sliding member 212 is always coupled with the base 211 during the movement and prevent it from being separated when subjected to lateral or jolt force, the cross-sectional profile of the sliding groove 211a is preferably designed to have a shape with a restraining capability, such as a T-shaped groove or a dovetail groove. Correspondingly, on the sliding member 212, the surface thereof facing the base 211 is integrally formed or fixedly connected with a protrusion 212a (which can be understood as a T-shaped or dovetail-shaped guide rail portion below the sliding member 212) that precisely matches the profile of the sliding groove 211a. The protrusion 212a is slidably accommodated in the sliding groove 211a, so that the sliding member 212 can only move in a single direction (i.e., the axial direction of the insulating rod 100) defined by the sliding groove 211a, while the freedom in other directions is completely restricted, ensuring the stability of the movement and the stability of the buffering process.

[0027] Of course, those skilled in the art can understand that the opposite configuration can also be adopted, i.e., the sliding groove 211a is arranged on the sliding member 212, and the matching protrusion 212a (or guide rail) is arranged on the base 211, which can also achieve the same sliding guiding function, and the present application does not limit this.

[0028] Optionally, as Figure 5 As shown, in some embodiments, in order to facilitate the efficient assembly of the sliding member 212 to the base 211, one end (e.g., the end away from the unmanned aerial vehicle body) of the sliding groove 211a on the base 211 can be designed as an open structure. During assembly, the protrusion 212a of the sliding member 212 can be easily pushed into the sliding groove 211a from the open end. After the assembly is completed, in order to prevent the sliding member 212 from sliding out of the open end, a separate baffle can be installed to close the open end.

[0029] Further, in order to control the relative sliding between the sliding member 212 and the base 211, in some embodiments, the movable seat assembly 210 is further provided with a first elastic member. For example, the first elastic member (e.g., a helical compression spring) is accommodated inside the sliding groove 211a. One end of the first elastic member abuts against the inner side wall of the sliding groove 211a (e.g., near the end close to the UAV body), and the other end abuts against the side wall of the protrusion 212a on the sliding member 212. In the normal working state, the first elastic member is in its natural length or slightly pre-compressed state, and the elastic force of the first elastic member pushes the sliding member 212 to the front end of its movement stroke, ensuring that the sensor is in the predetermined detection position. When the detection mechanism 200 is subjected to a frontal collision along the length direction of the insulating rod, the external impact force will force the sliding member 212 to retreat against the elastic force of the first elastic member. In this process, the first elastic member is compressed, converting the kinetic energy of the impact into its own elastic potential energy, thereby achieving absorption and dissipation of the axial impact energy, playing a buffering protection role. When the external impact force disappears, the elastic potential energy stored in the first elastic member is immediately released, pushing the sliding member 212 to automatically reset, so that it returns to the initial working position, without the need for manual intervention, and is ready for the next impact.

[0030] Similarly, for the buffering of lateral impact, in some embodiments, a second elastic member is further provided between the swing member 213 and the sliding member 212. For example, as shown in Figure 5 the swing member 213 rotates around the pivot joint with the sliding member 212, and the first end (i.e., the end away from the pivot) is used to mount or integrate the sensor (not shown in the figure). On the other side of the pivot, a second end is provided, which can be understood as a force arm for applying a restoring torque. The two ends of the second elastic member (not shown in the figure, for example, it can be a high-elasticity rubber ring or a tension spring) are reliably connected to the second end of the swing member 213 and a fixed point of the sliding member 212, respectively. In the normal working state, the second elastic member is in a slight tension state, and the tension generated by the second elastic member applies a "centering" torque to the swing member 213, so that the swing member 213 (and the sensor) remains straight and aligned with the axis of the insulating rod 100. When the sensor is impacted from the side, the swing member 213 will be deflected around the pivot, which will further stretch the second elastic member. The second elastic member absorbs the energy of the lateral impact during the stretching process. When the lateral impact force disappears, the stretched second elastic member will immediately retract, and the restoring torque generated by the second elastic member will drive the swing member 213 to quickly and accurately swing back to the initial centered position, achieving automatic reset in the lateral direction.

[0031] In summary, through the coordinated work of the first elastic member and the second elastic member, the detection device carried by the drone of the embodiment constructs a complete, automatically resettable passive buffer system, which can cope with the dual impact threats from the front and the side, and improves the reliability and environmental adaptability of the device.

[0032] It is understandable that in some embodiments, in order to firmly mount the detection device as an independent accessory on the drone body, the detection device carried by the drone in the embodiment further includes at least one supporting base 400. For example, Figure 1 and Figure 5 As shown, the support base 400 is provided with a channel or clamping structure for passing and securing the insulating rod 100. Its inner diameter matches the outer diameter of the insulating rod 100. The support base 400 also has a standardized mounting interface for connecting to the drone body. This mounting interface can be designed in a variety of forms to accommodate different drone platforms. For example, it can be a flat surface with standard threaded holes that can be directly fixed to the drone's reserved mounting points via screws. Alternatively, it can be designed to be compatible with the bayonet or slide rails of mainstream drone quick-release systems on the market, enabling tool-free rapid assembly and disassembly. By providing this independent support base 400, the entire detection device can be quickly mounted or removed as a complete unit, greatly improving deployment efficiency for field operations. For longer or heavier insulating rods 100, two or more support bases 400 can be used to secure them, ensuring rigidity and stability of the installation and preventing vibration during flight.

[0033] It is understandable that in some embodiments, the detection device carried by the embodiment drone adopts a highly modular design. For example, both the front detection mechanism 200 (specifically its base 211 part) and the rear control mechanism 300 are integrally formed or integrated with a clamping structure 214 that is compatible with the insulating rod 100. For example, Figure 5 and Figure 6As shown, the clamping structure 214 is generally designed as a semi-enclosed clasp with elasticity, or as a clamping structure fastened by two or more parts through bolts. Its inner wall profile is precisely matched with the circular cross-section of the insulating rod 100, providing sufficient clamping force while facilitating installation, disassembly or position adjustment. The core advantage of this design is to achieve detachable connection. The operator can easily clamp the detection mechanism 200 and the control mechanism 300 to any desired position on the insulating rod 100. For example, the position of the control mechanism 300 can be fine-tuned according to the center of gravity of the UAV to achieve the best 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) fails, only the corresponding module needs to be replaced, without discarding the entire device, significantly reducing maintenance costs.

[0034] As can be understood, in some embodiments, in order to achieve stable connection between the sensor and the swing piece 213 and make the structure of the entire detection mechanism 200 more compact, the overall geometric shape of the swing piece 213 can be designed to match the contour of the sensor. As can be understood, the swing piece 213 is not a general mounting bracket, but a component specially designed for a specific sensor. For example, as shown in Figure 1 and Figure 5 As shown, the inside of the swing piece 213 is integrally formed or processed with a receiving cavity 213a that is precisely matched with the outer shape of the sensor to be carried. In other words, the swing piece 213 itself is like a "exoskeleton" or "protective shell" specially designed for the sensor. In assembly, the sensor body (including its internal sensing coil, circuit board and other delicate components) is completely and tightly placed in the receiving cavity 213a and finally fixed by means of glue, buckle or micro screw. The strong shell of the swing piece 213 provides all-round wraparound protection for the relatively fragile sensor inside, effectively resisting environmental factors such as scratching, dust and moisture, and absorbing and dispersing impact force as the first line of defense when a collision occurs, avoiding stress acting directly on the sensor body; at the same time, by combining the mechanical function of "swinging" with the carrying function of "containing", the number of parts is greatly simplified, the assembly complexity is reduced, and the manufacturing cost is reduced. The front end of the entire detection mechanism 200 looks more simple, compact and professional.

[0035] As can be understood, the control mechanism 300 is the energy center and intelligent core of the entire detection device and is housed within the housing. For example, the control mechanism 300 integrates an independent power supply (e.g., a lightweight, high-capacity lithium battery) and a controller (e.g., a circuit board integrating a microprocessor and wireless communication chip). The power module, via wires housed within the insulating rod 100, provides a stable, pure operating voltage to the sensors in the remote detection mechanism 200, ensuring accurate measurements. The controller is responsible for sending commands to the sensors, such as starting or stopping detection or adjusting parameters, and receiving raw sensing signals from the sensors in real time. The controller also performs necessary processing on the received signals, such as amplification, filtering, and digital conversion. The controller then wirelessly transmits the processed data via its built-in wireless communication unit (e.g., a Wi-Fi or Bluetooth module) to a ground operator's handheld terminal (e.g., a mobile app, tablet) or the drone's remote control, enabling real-time display and recording of the data.

[0036] It is understandable that in order to facilitate the maintenance and disassembly of the control mechanism 300, as shown in FIG. Figure 6 As shown, in some embodiments, the housing comprises a power box 310 and a controller box 320. For example, the power box 310 provides a compartment for accommodating a power module (not shown), such as one or more batteries, and includes an opening for convenient access to the batteries. The controller box 320 can be designed to fit within the opening of the power box 310. The controller box 320 serves as a cover for the power box 310, tightly fitting over the opening. The two are securely and removably secured via fasteners such as snaps or screws. This integration of two functional components (the controller box 320 and the power box 310 cover) reduces the number of parts and makes the entire control mechanism 300 more compact and lightweight. Furthermore, when batteries need to be replaced or charged, the operator simply removes the controller housing, which serves as the "cover," to easily access the power module within, making the entire process more convenient and efficient. The power module provides a stable and pure operating voltage to the sensor in the remote detection mechanism 200 through the wires housed in the insulating rod 100, ensuring that it can perform accurate measurements.

[0037] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features of the embodiments can be combined with each other unless there is a conflict.
