[0002] With the continuous development of power transmission technology, the number of transmission lines is constantly increasing, which increases the workload of power distribution inspection personnel. Therefore, inspection equipment is often installed on transmission lines.

[0003] In related technologies, inspection equipment may generate induced electricity during line inspection, which can affect the control and communication functions of the equipment. Therefore, by configuring the inspection equipment with a spring-loaded conductive structure, the spring-loaded conductive structure slides and rubs against the power line during the movement of the equipment, ensuring a reliable equipotential connection between the equipment casing and the power line.

[0004] However, the frictional resistance of the aforementioned spring-type conductive structure is high, which can easily affect the efficiency of mobile inspection equipment. Utility Model Content

[0016] In one possible implementation, the conductive mechanism provided in this application includes a housing and a conductive component. The housing is disposed between two fork arms and positioned above a portion of the conductive wheel. The conductive component is connected to one of the two fork arms via the housing. The conductive component contacts the portion of the conductive wheel, thereby electrically connecting the conductive wheel to the fork arm.

[0017] In one possible implementation, the conductive mechanism provided in this application has a housing component connected to one of the two fork arms to jointly form a receiving cavity; the conductive component is located inside the receiving cavity and is connected to one of the two fork arms; the housing component has a clearance opening on the side facing part of the conductive wheel to avoid the conductive component, and the conductive component contacts part of the conductive wheel through the clearance opening.

[0018] In one possible implementation, the conductive mechanism provided in this application includes the following conductive elements:

The first connecting part is used to connect to the equipment body of the inspection equipment. The conductive wheel is rotatably connected to the second connecting part.

[0028] During the inspection process as the equipment moves along the extension direction of the power transmission line, the conductive wheel forms rolling contact with the power transmission line, which helps reduce contact friction resistance. Simultaneously, when encountering conditions such as changes in the diameter of the power transmission line, sag fluctuations, or external vibrations, the second connecting part can rotate relative to the first connecting part, thereby adjusting the position and attitude of the conductive wheel to maintain good contact with the power transmission line, reducing jamming and ensuring smooth movement. Furthermore, by placing the conductive component between the first and second connecting parts, the conductive wheel forms a reliable conductive path with the equipment body through the support. Thus, the power transmission line achieves equipotential connection with the equipment body via the conductive wheel, conductive component, support, and equipment body, thereby helping to reduce or eliminate the potential difference between them and lowering the risk of arc discharge.

[0045] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0046] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components.

[0047] In the description of this application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0048] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in a sequence other than those illustrated or described herein.

[0049] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0050] As mentioned in the background section, in related technologies, inspection equipment may generate induced electricity during line inspection, which can affect the control and communication functions of the inspection equipment. Therefore, by configuring the inspection equipment with a spring-loaded conductive structure, the spring-loaded contact slides against the power line during the movement of the inspection equipment, thereby maintaining a reliable equipotential connection between the inspection equipment casing and the power line.

[0051] However, the conductive spring needs to be pressed firmly against the surface of the power line with significant positive pressure to ensure reliable contact and stable conductivity. During the movement of the inspection equipment, this continuous surface-to-surface sliding friction causes significant frictional resistance between the spring and the power line. Furthermore, due to the spring's rigid structure, it is difficult for it to adaptively adjust its contact state with the conductor when encountering changes in power line diameter, sag, or external vibrations during the inspection equipment's movement. This can easily lead to further increases in contact pressure or even jamming. Therefore, this continuous and unstable high frictional resistance slows down the inspection equipment's movement along the power line, ultimately negatively impacting inspection efficiency.

[0052] In view of this, embodiments of this application provide a conductive mechanism, an inspection device, and a transmission line inspection system. The conductive mechanism is provided by setting a bracket and a conductive structure. The conductive structure includes a conductive wheel and a conductive component. The bracket has a first connecting part and a second connecting part that are opposite to each other. The first connecting part and the second connecting part are rotatably connected. The first connecting part is used to connect to the equipment body of the inspection device. The conductive wheel is rotatably connected to the second connecting part.

[0053] During the inspection process as the equipment moves along the extension direction of the power transmission line, the conductive wheel forms rolling contact with the power transmission line, which helps reduce contact friction resistance. Simultaneously, when encountering conditions such as changes in the diameter of the power transmission line, sag fluctuations, or external vibrations, the second connecting part can rotate relative to the first connecting part, thereby adjusting the position and attitude of the conductive wheel to maintain good contact with the power transmission line, reducing jamming and ensuring smooth movement. Furthermore, by placing the conductive component between the first and second connecting parts, the conductive wheel forms a reliable conductive path with the equipment body through the support. Thus, the power transmission line achieves equipotential connection with the equipment body via the conductive wheel, conductive component, support, and equipment body, thereby helping to reduce or eliminate the potential difference between them and lowering the risk of arc discharge.

[0054] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0055] See Figures 1 to 5The conductive mechanism 100 provided in this application embodiment includes a bracket 110 and a conductive structure. The bracket 110 has a first connecting portion 111 and a second connecting portion 112 opposite to each other. The first connecting portion 111 and the second connecting portion 112 are rotatably connected. The first connecting portion 111 is used to connect with the equipment body 200 of the inspection equipment. The conductive structure includes a conductive wheel 121 and a conductive component 120. The conductive wheel 121 is rotatably connected with the second connecting portion 112. The second connecting portion 112 is used to rotate relative to the first connecting portion 111 during the process of moving along the extension direction of the transmission line under the drive of the equipment body 200, so that the conductive wheel 121 maintains rolling contact with the transmission line. The conductive component 120 is located between the first connecting portion 111 and the second connecting portion 112. The conductive wheel 121 is conductively connected to the bracket 110 through the conductive component 120.

[0056] The bracket 110 serves as the supporting foundation for the entire conductive mechanism 100, and is provided with a first connecting part 111 and a second connecting part 112 arranged opposite to each other. The first connecting part 111 is used to fixally connect to the equipment body 200 of the inspection equipment, ensuring that the conductive mechanism 100 moves synchronously with the equipment. The first connecting part 111 and the second connecting part 112 are assembled by a rotatable connection, allowing the second connecting part 112 to rotate freely relative to the first connecting part 111 within a certain angle range.

[0057] The conductive wheel 121 is rotatably connected to the second connecting part 112, allowing it to roll along the surface of the power transmission line during the inspection equipment's movement. Rolling contact replaces traditional sliding friction, significantly reducing movement resistance and wear, thus improving inspection efficiency. When the power transmission line experiences changes in diameter, sag, or external disturbances such as wind vibration, the contact point position and stress state between the conductive wheel 121 and the power transmission line change. In this case, the second connecting part 112 can rotate relative to the first connecting part 111 following the movement trend of the conductive wheel 121, thereby adaptively adjusting the spatial posture of the conductive wheel 121. This ensures the conductive wheel 121 adheres to the surface of the power transmission line, preventing contact loss or mechanical jamming, thus guaranteeing the continuity of conductivity and the stability of equipment operation.

[0058] Understandably, in order to maintain rolling contact between the conductive wheel 121 and the transmission line, the second connecting portion 112 needs to rotate in the opposite direction to its original rotation direction after the disturbance disappears. For example, the second connecting portion 112 can be equipped with a magnetic reset structure, by installing permanent magnets on the first connecting portion 111 and the second connecting portion 112 respectively, for example, by arranging them in a way that the same poles face each other to form a repulsive force balance. Under normal operating conditions, the repulsive force between the magnets keeps the second connecting portion 112 in its initial equilibrium position. When the transmission line experiences sag changes or vibrations that cause a sudden change in the force on the conductive wheel 121, the second connecting portion 112 deflects, the distance between the magnets decreases, the repulsive force increases rapidly, and a restoring torque is generated in the opposite direction of deflection. This torque begins to act during the disturbance process, suppressing excessive deflection, and continues to push the second connecting portion 112 back to its original position after the disturbance weakens or disappears, ultimately restoring stable contact.

[0059] Alternatively, the second connecting part 112 may be equipped with a pneumatic damping reset mechanism, which includes a cylinder fixed to the first connecting part 111, a sealed chamber inside the cylinder, and a piston movably disposed in the chamber and rigidly connected to the second connecting part 112 via a linkage mechanism or directly, so that the rotational movement of the second connecting part 112 can be converted into the axial reciprocating movement of the piston inside the cylinder.

[0060] During the operation of the inspection equipment, when the power transmission line experiences localized elevation, reduced sag, or upward vibration due to wind, the conductive wheel 121 experiences an upward contact force, causing the second connecting part 112 to deflect upward around its axis of rotation with the first connecting part 111. At this time, the end of the second connecting part 112 connected to the piston rod moves downward or inward, pushing the piston into the cylinder and compressing the sealed gas chamber in front of it. The chamber volume decreases, the gas is compressed, and the pressure rapidly increases, forming a high-pressure air cushion that stores elastic potential energy. When the external disturbance weakens or disappears, the power transmission line returns to its normal position, and the upward force on the conductive wheel 121 decreases. The compressed high-pressure gas then begins to expand, pushing the piston in the opposite direction (i.e., outward), which in turn drives the second connecting part 112 downward through a connecting rod or direct drive, gradually restoring it to its initial equilibrium position. This ensures that the conductive wheel 121 re-stably contacts the surface of the power transmission line, maintaining reliable rolling contact and equipotential bonding.

[0061] Furthermore, to achieve electrical conductivity, a conductive component 120 is disposed between the first connecting portion 111 and the second connecting portion 112 to establish a stable conductive path. The conductive component 120 can be a sliding electrical contact structure employing a conductive brush and a conductive ring, braided soft copper wire, or a conductive slip ring. This ensures that even during continuous rotation or oscillation of the second connecting portion 112, current can still be stably conducted from the conductive wheel 121 through the second connecting portion 112, the conductive component 120, and the first connecting portion 111 to the support 110, ultimately forming an electrical connection with the equipment body 200. Overall, while ensuring mechanical flexibility, reliable equipotential bonding is maintained, effectively eliminating the potential difference between the equipment casing and the transmission line, and reducing the risk of arc discharge.

[0062] In summary, the conductive structure provided in this application embodiment allows the conductive wheel 121 to roll into contact with the power transmission line during the inspection process of the equipment body 200 moving along the extension direction of the power transmission line, which helps reduce contact friction resistance. Simultaneously, when encountering conditions such as changes in the diameter of the power transmission line, sag fluctuations, or external vibrations, the second connecting part 112 can rotate relative to the first connecting part 111, thereby driving the conductive wheel 121 to adjust its position and posture, maintaining good contact with the power transmission line at all times, which helps reduce jamming and ensures smooth movement. Furthermore, by placing the conductive component 120 between the first connecting part 111 and the second connecting part 112, the conductive wheel 121 forms a reliable conductive path with the equipment body 200 through the bracket 110. Thus, the power transmission line achieves equipotential connection with the equipment body 200 via the conductive wheel 121, the conductive component 120, and the bracket 110, thereby helping to reduce or eliminate the potential difference between them and reduce the risk of arc discharge.

[0063] See Figure 1 and Figure 3 In some examples, the bracket 110 includes two fork arms 113, one end of which is rotatably fitted onto the first connecting part 111, and the second connecting part 112 is connected between the other ends of the two fork arms 113; the fork arms 113 are used to follow the second connecting part 112 and the conductive wheel 121 to rotate relative to the first connecting part 111.

[0064] In this configuration, one end of each of the two fork arms 113 is mounted together on the first connecting part 111 via a rotatable connection, allowing the two fork arms 113 to rotate relative to each other within a certain angular range around the axis of the first connecting part 111.

[0065] When the inspection equipment encounters undulations, sag changes, or external vibrations along the power transmission line, the contact force between the conductive wheel 121 and the power transmission line changes, pushing the second connecting part 112 to cause the two fork arms 113 to swing around the first connecting part 111. Because the two fork arms 113 move synchronously, the rotation of the second connecting part 112 is smoother, preventing lateral deviation or jamming, thus ensuring that the conductive wheel 121 always maintains good contact with the power transmission line.

[0066] In a specific example, the fork arm 113 includes a connecting section 1132 and a fixing section 1133 arranged sequentially. The connecting section 1132 is rotatably sleeved on the first connecting part 111, and the end of the fixing section 1133 away from the connecting section 1132 is connected to the second connecting part 112.

[0067] The connecting segment 1132 is rotatably mounted on the first connecting part 111, allowing the swing of the fork arm 113 to adapt to the sag or vibration of the transmission line in the vertical direction. The end of the fixed segment 1133 furthest from the connecting segment 1132 is connected to the second connecting part 112, so that the position of the second connecting part 112 is supported by the two fixed segments 1133, which improves the rigidity and torsional resistance of the overall structure and avoids uneven loading or deformation caused by unilateral force.

[0068] For example, the inner wall of the sleeve section 1132 may be provided with a through hole or an annular groove, so that it can be rotatably sleeved on the first connecting part 111; the second connecting part 112 spans between the ends of the fixed sections 1133 of the two fork arms 113, and together they can form a stable U-shaped or frame-type load-bearing structure.

[0069] It should be noted that the socket section 1132 and the fixing section 1133 can be integrally formed or fixed by welding. This application embodiment does not limit this, as long as good connection strength is ensured. For example... Figure 1 and Figure 3 As shown, the connecting section 1132 and the fixing section 1133 are arranged perpendicularly to make the fork arm 113 L-shaped. This facilitates optimized spatial layout and improves structural compactness during assembly.

[0070] See Figures 1 to 5 In some embodiments, a torsion spring 114 is wound around the sleeve segment 1132. One end of the torsion spring 114 is hooked to the fixed segment 1133, and the other end abuts against the first connecting part 111. The torsion spring 114 is configured to undergo elastic deformation under the action of external force during the rolling of the conductive wheel 121, so as to allow the fixed segment 1133 to drive the second connecting part 112 to rotate, so that the conductive wheel 121 and the power transmission line maintain elastic rolling contact.

[0071] Thus, the placement and connection method of the torsion spring 114 allow its elastic force to be directly applied to the relative rotating part 1212 between the sleeve section 1132 and the first connecting part 111. This enables it to instantly generate a restoring torque when the second connecting part 112 deflects, effectively participating in torque adjustment during rotation, resulting in rapid response and reliable operation. Furthermore, since the torsion spring 114 is installed in the connection area between the fork arm 113 and the first connecting part 111, it can be close to the rotating engagement position formed by the two, resulting in a compact structure, high space utilization, and reduced energy loss. This also helps maintain stable and continuous elastic rolling contact between the conductive wheel 121 and the power transmission line.

[0072] For example, when the conductive wheel 121 encounters undulations, sag changes, or external vibrations while rolling on the surface of the power transmission line, the force on the conductive wheel 121 changes, causing the second connecting part 112 and the fixed section 1133 connected to it to rotate relative to the first connecting part 111 around the sleeve section 1132. At this time, the torsion spring 114 undergoes elastic torsional deformation, storing elastic potential energy. This elastic deformation allows the second connecting part 112 to swing freely within a certain angle range, enabling the conductive wheel 121 to adaptively conform to the surface of the power transmission line, avoiding jumping or jamming caused by rigid contact. Simultaneously, because the torsion spring 114 always applies a restoring torque, an elastic rolling contact is formed between the conductive wheel 121 and the power transmission line, with stable and controllable contact pressure, ensuring reliable conductivity while avoiding excessive frictional resistance.

[0073] Furthermore, when the external disturbance weakens or disappears, the potential energy stored in the torsion spring 114 is released, and its restoring torque drives the fixed section 1133 to rotate the second connecting part 112 back to the initial equilibrium position, so that the conductive wheel 121 quickly returns to the preset contact state, ensuring the continuity of the equipotential connection.

[0074] See Figure 1 In some examples, the first connecting part 111 includes a connecting section 1111 and a supporting section 1112. The connecting section 1111 is used to connect with the device body 200. The connecting section 1111 has a mounting area 1113. The supporting section 1112 is located on the mounting area 1113 and is connected to the connecting section 1111. The fork arm 113 is rotatably sleeved on the supporting section 1112.

[0075] Thus, the first connecting part 111 is fixedly connected to the equipment body 200 through the connecting section 1111, and supports the fork arm part 113 through the support section 1112. The functions of each part are clearly defined, which is conducive to improving structural reliability and facilitating assembly and maintenance.

[0076] The connecting section 1111 serves as the main body of the first connecting part 111 and is used to fix it to the equipment body 200 of the inspection equipment. For example, it can be installed securely by means of threaded connection, bolt fastening or snap-fit, so as to ensure that the entire conductive mechanism 100 moves synchronously with the equipment.

[0077] By setting the installation area 1113 on the connection segment 1111, such as Figure 1 As shown, the installation area 1113 can be a groove-shaped structure used to accommodate and position the support section 1112.

[0078] For example, the axial length and outer diameter of the support section 1112 are adapted to the structural requirements of the fork arm 113 to ensure that the two fork arms 113 can be reasonably arranged to avoid interference or skew during operation.

[0079] See Figures 1 to 5 In a specific example, both the support section 1112 and the second connecting part 112 are support shafts.

[0080] Here, both the support section 1112 and the second connecting part 112 are axial structures and are parallel to each other. The support section 1112 is fixed, while the second connecting part 112 swings around the support section 1112 with the fork arm 113, achieving posture adjustment. Overall, the dual-axis layout is simple, conducive to balancing forces and reducing off-center loads, and facilitates the integration of components such as the torsion spring 114 and the conductive element 122, resulting in good overall reliability and ease of assembly for the conductive mechanism 100.

[0081] See Figure 3 and Figure 6 In some examples, the conductive component 120 includes a housing 123 and a conductive element 122. The housing 123 is disposed between two fork arms 113 and above a portion of the conductive wheel 121. The conductive element 122 is connected to one of the two fork arms 113 through the housing 123. The conductive element 122 contacts the portion of the conductive wheel 121, thereby electrically connecting the conductive wheel 121 to the fork arm 113.

[0082] The housing component 123 is provided, which may have a guide groove or a limiting structure to constrain the movement trajectory of the conductive component 122, prevent it from shifting or loosening, and improve the structural stability of the conductive component 122.

[0083] For example, such as Figure 3 and Figure 7As shown, the conductive wheel 121 may include a wheel body 1211 and a rotating part 1212 coaxially connected to the wheel body 1211. Two conductive bearings 124 are spaced apart on the second connecting part 112. The wheel body 1211 is rotatably mounted on the two conductive bearings 124 via the rotating part 1212. Overall, the conductive bearings 124 provide mechanical support for the conductive wheel 121 and also have electrical conductivity, thus improving the reliability of electrical conductivity.

[0084] Furthermore, the housing 123 is located above the rotating part 1212, the conductive element 122 contacts the rotating part 1212 via the clearance opening 1231, and the wheel 1211 is used for rolling contact with the power transmission line. That is, the conductive element 122 contacts a portion of the conductive wheel 121, that is, the conductive contact point between the conductive element 122 and the conductive wheel 121 is located on the rotating part 1212 rather than on the outer periphery of the wheel 1211, which helps to avoid areas of external contamination and severe wear, and improves conductive stability.

[0085] In a specific example, the housing 123 is connected to one of the two fork arms 113 to jointly form a receiving cavity; the conductive element 122 is located inside the receiving cavity and is connected to one of the two fork arms 113. The housing 123 has a clearance opening 1231 on the side facing the partial conductive wheel 121 to avoid the conductive element 122, and the conductive element 122 contacts the partial conductive wheel 121 through the clearance opening 1231.

[0086] Thus, the cavity is used to house and protect the conductive component 122, preventing external dust, rainwater, or foreign objects from entering and causing poor contact or insulation failure, thereby improving the reliability of the conductive connection and environmental adaptability.

[0087] The housing 123 can be securely installed with one of the two fork arms 113 by means of screws, clips or welding, or the housing 123 and one of the two fork arms 113 are integrally formed.

[0088] See Figure 3 In some examples, the conductive element 122 includes an elastic portion 1221 and a carbon brush portion 1222. One end of the elastic portion 1221 is connected to one of the two fork arms 113. The carbon brush portion 1222 is connected to the other end of the elastic portion 1221, and a portion of the carbon brush portion 1222 contacts a portion of the conductive wheel 121 via a clearance opening 1231.

[0089] Thus, the elastic part 1221 and the carbon brush part 1222 together constitute a floating and conductive electrical connection structure to ensure continuous and stable electrical contact between the conductive wheel 121 and the fork arm part 113.

[0090] The elastic part 1221 serves as a support and force-applying component for the conductive element 122. One end of it is fixedly connected to one of the two fork arms 113. The connection method can be welding or snap-fit ​​to ensure a low-resistance connection in the current conduction path. The elastic part 1221 can be a helical spring or a spring sheet, made of conductive metal material, such as spring steel, phosphor bronze, or beryllium copper, which combines conductivity and elastic recovery capability, enabling it to deform under pressure and return to its original shape after the external force is released.

[0091] The carbon brush portion 1222 is connected to the other end of the elastic portion 1221, and a strong and electrically conductive connection can be achieved through riveting, crimping, or welding. The carbon brush portion 1222 is made of conductive and wear-resistant material, usually carbon-based or graphite-based composite material, which has good self-lubricating properties and anti-arc erosion performance, making it suitable as a sliding electrical contact component.

[0092] In the assembled state, a portion of the carbon brush portion 1222 extends outward through the clearance opening 1231 on the housing 123 and maintains a tight contact with the outer peripheral surface of the conductive wheel 121. Because the elastic portion 1221 provides continuous elastic preload, the carbon brush portion 1222 can adhere tightly to the surface of the conductive wheel 121. Even if the conductive wheel 121 experiences slight vibrations due to vibration or fluctuations in the power line during equipment operation, the carbon brush portion 1222 can maintain stable contact, preventing momentary open circuits or a sharp increase in contact resistance.

[0093] See Figure 1 , Figure 5 and Figure 8 In some embodiments, the conductive mechanism 100 further includes a sensing component 130, which includes a magnet 131 and at least two Hall elements 132 for sensing the magnet 131. The magnet 131 is connected to the conductive wheel 121. Each Hall element 132 is arranged adjacent to each other on the device body 200. The magnet 131 is used to rotate with the conductive wheel 121 to generate relative motion with the Hall element 132. The Hall element 132 is used to be electrically connected to the control unit 210 of the device body 200. The control unit 210 is used to obtain the operating information of the conductive wheel 121 based on the sensing information of each Hall element 132.

[0094] It is understood that by setting at least two Hall elements 132, the operating information of the conductive wheel 121 can include the rotational speed of the conductive wheel 121, the distance traveled by the conductive wheel 121 along the extension direction of the power transmission line, and the rolling direction of the conductive wheel 121.

[0095] Since the conductive wheel 121 maintains rolling contact with the power transmission line, the rotation state of the conductive wheel 121 can more accurately reflect the actual operating state of the equipment body 200. The control component 210 can accurately measure and provide feedback on the moving speed, cumulative mileage, and moving direction of the inspection equipment by combining the pulse signal frequency, cumulative quantity, and timing relationship output by the Hall element 132 with the circumference parameter of the conductive wheel 121.

[0096] For example, since the magnet 131 and the conductive wheel 121 rotate synchronously, the Hall element 132 outputs a pulse for each complete rotation. Therefore, the controller 210 can calculate the rotational speed of the conductive wheel 121 based on the pulse frequency per unit time. Specifically, the controller 210 may internally include a timing module and a counting logic circuit or a processor running a corresponding algorithm. By counting the number of pulses within a preset time period, combined with the transmission relationship between the magnet 131 and the conductive wheel 121 and the circumference parameter of the conductive wheel 121, the real-time moving speed of the conductive wheel 121 along the extension direction of the power transmission line can be derived. At the same time, the controller 210 records the total number of pulses accumulated by any Hall element 132, i.e., the total number of rotations of the corresponding conductive wheel 121. By multiplying this by the circumference of the conductive wheel 121, the cumulative mileage traveled by the conductive wheel 121 since the starting point can be obtained.

[0097] Furthermore, the control unit 210 receives and analyzes the timing relationship of the signals output by each Hall element 132. For example, by comparing the order in which adjacent Hall elements 132 generate signals, the control unit 210 can determine the rotation direction of the conductive wheel 121, that is, determine whether the inspection equipment moves forward or backward along the transmission line.

[0098] Combination Figure 5 As shown, in a specific implementation, the device body 200 has a protective cover 133, which is used to cover each Hall element 132 to protect the Hall element 132.

[0099] This application also provides an inspection device, including a device body 200 and a conductive mechanism 100 as described in any of the above embodiments disposed on the device body 200.

[0100] The overall structure and working principle of the conductive mechanism 100 are the same as those in the previous embodiments, and will not be described again in this embodiment.

[0101] Specifically, the equipment body 200 serves as the main structure of the inspection equipment, and is used to carry various functional modules, such as sensor components, communication modules, and power systems.

[0102] For example, the sensor assembly may include a visible light camera and an infrared thermal imager for capturing images of the surface condition of transmission lines and insulators and detecting abnormal heat points. The sensor assembly may also include attitude sensors (such as gyroscopes and accelerometers) for monitoring the equipment's operating attitude, as well as environmental monitoring components such as wind speed sensors and temperature and humidity sensors to improve the integrity of inspection data and operational safety. A communication module can be used to enable bidirectional data interaction between the inspection equipment and the ground monitoring terminal. A power system is used to provide a stable power supply to the entire equipment. The power system may include a rechargeable battery pack (such as a lithium battery), an energy harvesting device (such as a solar panel), and a power management circuit.

[0103] The equipment body 200 can employ either an upper / lower clamping structure or a left / right enclosing structure to suspend and move the transmission line. In the upper / lower clamping structure, the equipment body 200 clamps the transmission line using a drive wheel and a driven wheel working together, maintaining a stable posture with gravity assistance, and achieving autonomous movement along the transmission line through the rotation of the drive wheel. In the left / right enclosing structure, the equipment body 200 includes two openable and closable housings. During operation, the two housings close symmetrically from left to right, enclosing the transmission line in a ring-like contact.

[0104] Reference Figure 8 In some embodiments, the device body 200 includes a control unit 210, and the Hall element 132 of the conductive mechanism 100 is electrically connected to the control unit 210; the control unit 210 is used to obtain the operating information of the conductive wheel 121 based on the sensing information of each Hall element 132.

[0105] Among them, the control unit 210 refers to an electronic control unit that can receive and process the output signal of the sensing element, and calculate and output the running information of the conductive wheel 121 based on the signal. It can be the core control and data processing module of the device body 200, such as a microcontroller, programmable logic controller or digital signal processor.

[0106] This application also provides a power transmission line inspection system, including any of the inspection devices described in the above embodiments.

[0107] The overall structure and operating principle of the inspection equipment are the same as those in the aforementioned embodiments, and will not be described again in this application.

[0108] For example, the transmission line inspection system may also include a ground monitoring terminal, which is set up at maintenance stations or mobile work vehicles along the transmission line. It has a human-machine interface for receiving real-time data uploaded by the inspection equipment, including video images, infrared thermal images, equipment operating parameters and location information, and can perform visual monitoring and scheduling of inspection tasks.

[0109] Furthermore, the power transmission line inspection system may also include a drone installation and dismantling device. For example, it can work in conjunction with a drone by setting up a mechanical clamping mechanism, positioning and guidance components and a control drive unit to achieve safe and accurate transfer of inspection equipment between the ground and the power transmission line.

[0110] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
