[0001] This application relates to the field of inspection equipment technology, and in particular to an inspection equipment and inspection system. Background Technology

[0002] Overhead power transmission cables are an important component of the power grid. They are typically inspected using inspection equipment to ensure the safety of the power grid.

[0003] In related technologies, inspection equipment typically adopts a single-unit structure design, meaning the drive unit is integrated into the main body of the equipment, resulting in a relatively even distribution of the overall center of gravity. The drive wheels of the drive unit contact the surface of the overhead power transmission cable, utilizing friction to propel the inspection equipment along the conductor and perform inspection work.

[0004] However, the aforementioned inspection equipment is easily affected by the spiral structure of overhead power transmission cables when it moves, that is, the surface of overhead power transmission cables has periodic spiral protrusions, which causes it to become skewed and results in poor inspection stability.

[0018] In one possible implementation, the inspection equipment provided in this application further includes a first connector, through which the photovoltaic panel is connected to the equipment body.

[0019] In one possible implementation, the inspection equipment provided in this application includes two first connecting parts in the first connecting member. The two first connecting parts are arranged at intervals on the same side of the photovoltaic panel along the extension direction of the overhead power transmission cable. Both first connecting parts are connected to the photovoltaic panel. The two outer walls of the equipment body along the extension direction of the overhead power transmission cable are connected one-to-one with the two first connecting parts on the side away from the photovoltaic panel.

[0039] 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.

[0040] Overhead power transmission cables are an important component of the power grid. They are typically inspected using inspection equipment to ensure the safety of the power grid.

[0041] In related technologies, inspection equipment typically adopts a single-unit structure design, meaning the drive unit is integrated into the main body, resulting in a relatively even distribution of the overall center of gravity. The drive wheels of the drive unit contact the surface of the overhead power transmission cable, utilizing friction to propel the inspection equipment along the conductor and perform inspection work.

[0042] Specifically, overhead power transmission cables are usually made of multiple strands of metal conductors twisted together in a spiral manner to form a spiral braid structure. This structure is achieved during the manufacturing process by spirally winding multiple conductors around the center line at a certain pitch. This is used to improve the overall mechanical strength, flexibility and tensile performance of overhead power transmission cables, while also enhancing their environmental adaptability such as resistance to wind vibration and fatigue.

[0043] Understandably, when the inspection equipment moves along the conductor, its drive wheel contacts the surface of the overhead power transmission cable. Because the contact area of ​​the drive wheel is narrow and usually made of rigid material, the contact area is concentrated at the top of the spiral protrusion. As the inspection equipment continues to move, the contact point between the drive wheel and the spiral protrusion periodically shifts along the spiral direction. Due to the inclined trend of the spiral protrusion, the drive wheel experiences a lateral force along the spiral inclination direction during rolling. This lateral force is not constant but fluctuates alternately with the periodic changes of the spiral protrusion, but overall it continuously pushes the inspection equipment to tilt towards the side of the spiral protrusion.

[0044] Therefore, the aforementioned inspection equipment is easily affected by the spiral structure of overhead power transmission cables when it moves, that is, the surface of overhead power transmission cables has periodic spiral protrusions, which causes it to become skewed and results in poor inspection stability.

[0045] In view of this, this application provides an inspection device and an inspection system. The inspection device is used to travel on an overhead power transmission cable. The inspection device includes a device body and a counterweight mechanism configured on the device body. The device body is equipped with at least one drive wheel for rolling contact with the overhead power transmission cable to realize the movement of the inspection device. The counterweight mechanism is located below the drive wheel and the overhead power transmission cable. The counterweight mechanism is used to make the overall center of gravity of the inspection device located below the overhead power transmission cable, and to make the overall center of gravity and the center of mass of the device body located on both sides of the contact point between the drive wheel and the overhead power transmission cable, so that the inspection device is tilted when mounted.

[0046] In this way, by making the tilt direction of the inspection equipment opposite to the tilt direction caused by the spiral structure of the overhead power transmission cable, and by adjusting the tilt angle through the weight of the counterweight mechanism and the installation position, when the inspection equipment tilts due to the lateral force during its movement, the tilt posture can compensate for the tilt angle, thereby preventing the tilt angle from exceeding the safety threshold and causing the inspection equipment to derail. This helps to ensure the reliable suspension of the inspection equipment and improve the stability of the inspection.

[0047] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0048] See Figures 1 to 3 The inspection device 100 provided in this application embodiment is used to be mounted on an overhead power transmission cable 200 for movement. The inspection device 100 includes a device body 110 and a counterweight mechanism 120 disposed on the device body 110. The device body 110 is provided with at least one drive wheel 111 for rolling contact with the overhead power transmission cable 200. The counterweight mechanism 120 is located below the drive wheel 111 and the overhead power transmission cable 200. The counterweight mechanism 120 is configured such that the overall center of gravity of the inspection device 100 is located below the overhead power transmission cable 200, and the overall center of gravity and the center of mass of the device body 110 are respectively located on both sides of the contact point between the drive wheel 111 and the overhead power transmission cable 200, so that the inspection device 100 presents an inclined posture when mounted.

[0049] The main body 110 serves as the main structure of the inspection equipment 100 and can integrate various functional components required for inspection operations, such as a detection module for collecting cable status information, a control module for controlling equipment operation, and a power module for providing power to the equipment. At the same time, the main body 110 is also equipped with at least one drive wheel 111, which is used to form rolling contact with the overhead power transmission cable 200. The rotation of the drive wheel 111 can drive the entire inspection equipment 100 to move along the extension direction of the overhead power transmission cable 200, thereby realizing the movement of the inspection equipment 100 between different inspection positions and meeting the comprehensive inspection needs of the long-distance overhead power transmission cable 200.

[0050] The number of drive wheels 111 is not limited in this embodiment. In specific implementation, the number of drive wheels 111 can be reasonably set according to the overall weight of the inspection equipment 100, the requirements for travel stability, and the power output requirements. For example, two symmetrically distributed drive wheels 111 can be set to improve the stability of the equipment during travel and ensure that the drive wheels 111 and the overhead power transmission cable 200 always maintain reliable rolling contact.

[0051] As a key component for stabilizing the posture of the inspection equipment 100, the counterweight mechanism 120 is installed below the drive wheel 111 and the overhead power transmission cable 200. The counterweight mechanism 120 can be assembled onto the equipment body 110 by common mechanical connection methods such as bolt connection, snap-fit ​​fixing or welding to ensure that the assembly structure has sufficient strength so that the counterweight mechanism 120 will not loosen or fall off during the movement of the inspection equipment 100, thus ensuring its functional stability.

[0052] The counterweight mechanism 120 is used to adjust the overall center of gravity of the inspection equipment 100 by distributing its own weight. Specifically, the mechanism positions the center of gravity of the inspection equipment 100 below the overhead power transmission cable 200, and simultaneously positions the adjusted center of gravity and the center of mass of the equipment body 110 on opposite sides of the contact point between the drive wheel 111 and the overhead power transmission cable 200. It is understood that the center of mass of the equipment body 110 is usually located in the middle region due to the distribution of its internal functional components. The counterweight mechanism 120 alters the overall weight distribution of the inspection equipment 100, causing the center of gravity to deviate from the center of mass of the equipment body 110. Consequently, when the inspection equipment 100 is mounted on the overhead power transmission cable 200, it tilts under the influence of gravity.

[0053] For example, if the overhead power transmission cable 200 has a right-hand spiral structure and the inspection equipment 100 moves forward, the spiral protrusion will exert a rightward force on the drive wheel 111, that is... Figure 1 The lateral component of the force in the +X direction shown induces the inspection equipment 100 to deflect to the right. At this time, through the configuration of the counterweight mechanism 120, the inspection equipment 100 can be pre-positioned to the left, i.e. Figure 1 As shown, the tilt in the -X direction creates a reverse torque, which can effectively counteract some of the lateral disturbances, allowing the tilt attitude to compensate for the tilt angle and slow down the tilting trend.

[0054] Meanwhile, the weight and installation position of the counterweight mechanism 120 can be flexibly adjusted according to requirements, so that the tilt angle of the inspection equipment 100 can be precisely adapted to the spiral pitch and spiral tilt direction of different overhead power transmission cables 200. This ensures that the tilt posture of the inspection equipment 100 is compatible with the spiral structure of different overhead power transmission cables 200, effectively counteracting the tilt direction, reducing the impact of lateral force on the posture of the inspection equipment 100, and preventing the tilt angle from exceeding the safety threshold. This ensures that the inspection equipment 100 can always be stably mounted on the overhead power transmission cable 200, enabling the inspection operation to be carried out continuously and reliably.

[0055] See Figure 1 In some examples, the device body 110 has an inclined surface 101 on the side opposite to the drive wheel 111, and the inclined surface 101 has an angle α with the horizontal plane.

[0056] Thus, the slope 101 can adapt to the overall tilt of the equipment caused by the counterweight mechanism 120. At the same time, when the inspection equipment 100 moves along the overhead power transmission cable 200 in the outdoor environment, it often faces lateral wind load. The slope 101 structure can guide the airflow to pass smoothly through the equipment body 110, reduce eddy current generation and wind pressure fluctuation, thereby reducing the interference of wind on the posture of the inspection equipment 100 and improving the stability of operation.

[0057] In addition, the slope 101 can facilitate the sliding of rainwater, prevent water from accumulating on the top of the equipment body 110, reduce the risk of moisture damage to the electrical components integrated on the equipment body 110, and enhance the environmental adaptability of the inspection equipment 100 in rainy and snowy weather.

[0058] The inclined surface 101 extends from the upper part of the equipment body 110 downwards, i.e., from +Z to -Z in the figure. The angle α formed between the direction of the inclined surface 101 and the horizontal plane is used to reflect the tilt angle of the inspection equipment 100 in the mounted state.

[0059] For example, the included angle α is greater than 0° and less than 90°.

[0060] Thus, by setting the included angle α to be greater than 0°, the inclined plane 101 has a clear tilting trend, which can effectively guide the airflow to flow smoothly along the surface of the inspection equipment 100, reducing the eddies and wind resistance caused by sudden changes in the windward side during the journey; by setting the included angle α to be less than 90°, it is beneficial to control the state of the inspection equipment 100 mounted on the overhead power transmission cable 200, and ensure the mounting stability of the inspection equipment 100.

[0061] For example, the included angle α can be set to 30°, 40°, 60°, 70°, 75°, 80°, 85°, etc.

[0062] Reference Figure 1 and Figure 3 In some embodiments, the counterweight mechanism 120 includes a functional and counterweight integrated component.

[0063] In this way, the integrated functional and counterweight component serves as both a carrier or component of any functional module in the inspection equipment 100. At the same time, relying on its own sufficient mass density and reasonable position layout, it naturally assumes the counterweight function, thus eliminating the need to add an additional independent counterweight block, simplifying the assembly process, and achieving a lower center of gravity and posture stability without increasing the volume and weight redundancy of the inspection equipment 100.

[0064] Overall, the counterweight mechanism 120 combines functionality with counterweight, which helps to improve the space utilization and integration of the inspection equipment 100, and makes the overall structure of the inspection equipment 100 more compact.

[0065] See 2 and Figure 3 In a specific example, the integrated functional and counterweight component is the photovoltaic panel 121.

[0066] The photovoltaic panel 121 can be used as an energy harvesting device to power the inspection equipment 100. The photovoltaic panel 121 typically includes components such as glass, metal frame and high-density encapsulation material, and has a certain weight. When the photovoltaic panel 121 is set in the lower part of the equipment body 110, so that it is below the contact point between the drive wheel 111 and the overhead power transmission cable 200, the photovoltaic panel 121 can participate in the adjustment of the overall weight distribution of the machine, so that the overall center of gravity of the inspection equipment 100 is lowered to below the axis of the overhead power transmission cable 200.

[0067] In practice, the overhead power transmission cable 200 is located outdoors. When the inspection equipment 100 is running on the overhead power transmission cable 200, there is usually no obstruction above it, which provides good lighting conditions. The photovoltaic panel 121 can convert solar energy into electrical energy to provide power support for the control module and power module of the inspection equipment 100, extend the battery life, and meet the needs of long-term, long-distance unattended inspection tasks.

[0068] Furthermore, the installation angle and orientation of the photovoltaic panel 121 can be optimized according to the equipment's suspension posture. For example, after assembly, the photovoltaic panel 121 may appear as follows: Figure 3 The state shown allows the surface of the photovoltaic panel 121 to face the direction of solar incidence, thereby improving photoelectric conversion efficiency.

[0069] See Figure 3 In other examples, the integrated functional and counterweight component is battery 122.

[0070] Among them, the battery 122 can serve as the core energy storage unit of the inspection equipment 100, which is used to store electrical energy and supply power to the inspection equipment 100. At the same time, the battery 122 is usually composed of high-density electrochemical materials (such as lithium-ion cells) and metal casing, and has a large overall mass. When the battery 122 is placed in the lower area of ​​the equipment body 110, it can significantly affect the mass distribution of the whole machine, causing the overall center of gravity of the inspection equipment 100 to shift downward to below the axis of the overhead power transmission cable 200.

[0071] In some embodiments, the device body 110 includes a mounting member 113 and a clamping wheel assembly 112. The mounting member 113 is located below the drive wheel 111 and is connected to the counterweight mechanism 120. The clamping wheel assembly 112 is connected to the side of the mounting member 113 facing the drive wheel 111 and is used to clamp the overhead power transmission cable 200 together with the drive wheel 111.

[0072] The mounting component 113 serves as a support structure for connecting the counterweight mechanism 120, ensuring the structural reliability of the counterweight mechanism 120. By clamping the overhead power transmission cable 200 together with the tension wheel assembly and the drive wheel 111, sufficient contact pressure can be maintained between the drive wheel 111 and the conductor, improving friction and travel reliability.

[0073] like Figure 1 As shown, the equipment body 110 may further include a main frame 114 and an upper housing 115 connected to the main frame 114. The drive wheel 111 is connected to the upper housing 115, and the mounting member 113 is connected to the main frame 114. The clamping wheel assembly 112 is connected to the mounting member 113 on the side facing the drive wheel 111, that is, it is installed in the upper area of ​​the mounting member 113, so that the clamping wheel assembly 112 and the drive wheel 111 are arranged opposite to each other, so that a clamping channel for accommodating the overhead power transmission cable 200 is formed between them.

[0074] Since the mounting component 113 is located below the drive wheel 111, it works together with its own mass and the counterweight mechanism 120 it carries to further lower the overall center of gravity of the inspection equipment 100 to below the overhead power transmission cable 200, thereby enhancing the stability of the inspection equipment 100 in the suspended state.

[0075] For example, the clamping wheel assembly 112 may include at least one rotatable clamping wheel, and both the clamping wheel and the drive wheel 111 may be covered with an elastic material to increase the coefficient of friction with the contact surface of the overhead power transmission cable 200 and reduce mechanical damage to the surface of the overhead power transmission cable 200.

[0076] In practice, the mounting component 113 can be connected to the main frame 114 by welding or other fixing methods. Correspondingly, the clamping wheel assembly 112 can be slidably connected to the mounting component 113 via an adjustable connection. Alternatively, the mounting component 113 can be slidably connected to the main frame 114 via an adjustable connection, and the clamping wheel assembly 112 can be connected to the mounting component 113 via bolts or other fixing methods. This allows the clamping distance to be adjusted according to the diameter of the overhead power transmission cable 200, accommodating overhead cables of different specifications.

[0077] In some examples, the weight of the counterweight mechanism 120 is configured such that the ratio of the weight of the equipment body 110 to the total weight of the inspection equipment 100 is greater than or equal to 0.6 and less than or equal to 0.7.

[0078] In this way, the weight of the counterweight mechanism 120 accounts for 30% to 40% of the total weight of the machine. This proportion can ensure the significant effect of the counterweight, so that the overall center of gravity of the inspection equipment 100 can be effectively located below the overhead power transmission cable 200, forming a stable tilted suspension posture. At the same time, it can avoid the increase in drive energy consumption, the decrease in acceleration performance, or the excessive compressive stress on the overhead power transmission cable 200 caused by excessive counterweight.

[0079] For example, the ratio of the weight of the device body 110 to the total weight of the inspection device 100 can be set to 0.6, 0.62, 0.64, 0.65 or 0.7.

[0080] See Figure 3 In some embodiments, the inspection device 100 further includes a first connector, through which the photovoltaic panel 121 is connected to the device body 110.

[0081] Thus, the first connector is used to achieve a reliable connection between the photovoltaic panel 121 and the equipment body 110, ensuring that the photovoltaic panel 121 will not loosen, shift, or fall off due to vibration, wind load, etc. during the movement of the inspection equipment 100.

[0082] For example, the photovoltaic panel 121 is connected to the device body 110 through the first connector, that is, the photovoltaic panel 121 is connected to the mounting member 113 through the first connector. The mounting member 113 has a receiving cavity 1131 and includes an inner wall located inside the receiving cavity 1131 and an outer wall located outside the receiving cavity 1131.

[0083] When assembling the photovoltaic panel 121, the first connector can be used to securely install the photovoltaic panel 121 onto the outer wall of the mounting component 113 by means of bolts, clips, rivets, or welding, with the photovoltaic panel 121 located away from the drive wheel 111 and opposite to the equipment body 110. This avoids shading of the photovoltaic panel 121 and forms a connection structure with high mechanical strength and good long-term stability.

[0084] In a specific example, the first connector includes two first connecting parts 131. The two first connecting parts 131 are arranged at intervals on the same side of the photovoltaic panel 121 along the extension direction of the overhead power transmission cable 200. Both first connecting parts 131 are connected to the photovoltaic panel 121. The two outer walls of the equipment body 110 along the extension direction of the overhead power transmission cable 200 are connected one-to-one with the side of the two first connecting parts 131 away from the photovoltaic panel 121.

[0085] It is understandable that the extension direction of the overhead power transmission cable 200 is the same as the travel direction of the inspection equipment 100, which can be referenced. Figure 2 The Y direction in the middle. The two outer walls of the equipment body 110 along the extension direction of the overhead power transmission cable 200, i.e., the mounting parts 113, are along the Y direction. Figure 2 The two outer walls in the Y direction.

[0086] Thus, the two first connecting parts 131 form a double-point support structure, which helps to enhance the rigidity of the connection system, avoid structural deformation or connection failure due to excessive force at a single point, and improve the overall stability and torsional resistance of the photovoltaic panel 121.

[0087] For example, the first connecting part 131 can be a plate-shaped structure to facilitate processing and production. The first connecting part 131 and the photovoltaic panel 121 can be integrally formed or fixed by welding. The first connecting part 131 and the mounting part 113 can be fixed by screwing, riveting or welding.

[0088] Continue reading Figure 3 In some examples, the inspection device 100 also includes a second connector 132, through which the battery 122 is connected to the device body 110.

[0089] Thus, the second connector 132 is used to achieve a reliable connection between the battery 122 and the device body 110, ensuring that the battery 122 will not become loose, shift, or fall off due to vibration, wind load, etc. during the movement of the inspection device 100.

[0090] For example, the battery 122 is connected to the device body 110 via the second connector 132, that is, the battery 122 is connected to the mounting member 113 via the second connector 132. When assembling the battery 122, the second connector 132 can be used to securely install the battery 122 onto the inner wall of the mounting member 113 by means of bolts, clips, rivets or welding, so as to form a connection structure with high mechanical strength and good long-term stability.

[0091] Among them, such as Figure 3 As shown, the counterweight mechanism 120 can simultaneously assemble the photovoltaic panel 121 and the battery 122, and the battery 122 is arranged adjacent to the photovoltaic panel 121 to ensure that the inspection equipment 100 is tilted when mounted.

[0092] Specifically, the second connector 132 includes a second connector 1321 and a plurality of third connectors 1322. The second connector 1321 is connected to the device body 110 through at least a portion of the third connectors 1322, and the battery 122 is connected to the second connector 1321 through at least a portion of the third connectors 1322.

[0093] The second connecting part 1321 serves as an intermediate connecting body, fixed to the outer casing or mounting bracket of the battery 122 to form a stable load-bearing interface. The second connecting part 1321 is connected to the device body 110 through at least a number of third connecting parts 1322, and the battery 122 is connected to the second connecting part 1321 through at least a number of third connecting parts 1322, to form a multi-point connection structure that can evenly distribute the force, which is beneficial to improving the connection rigidity and preventing local stress concentration.

[0094] For example, the second connecting part 1321 can be a plate-like structure, and the third connecting part 1322 can be in the form of a threaded hole, slot or rivet point provided on the second connecting part 1321, for adapting to standard fasteners such as bolts, buckles or rivets, so as to facilitate assembly and disassembly and support modular replacement and maintenance of the battery 122.

[0095] In a specific implementation, an elastic gasket or buffer layer can also be provided between the second connection part 1321 and the battery 122 to absorb the vibration energy during the operation of the inspection equipment 100, protect the internal cell structure of the battery 122, and enhance the vibration and impact resistance of the connection structure.

[0096] This application also provides an inspection system, including an overhead power transmission cable 200 and an inspection device 100 as described in any of the above embodiments, wherein the inspection device 100 is mounted on the overhead power transmission cable 200 in an inclined manner.

[0097] The specific structure and working principle of the inspection equipment 100 are the same as those in the previous embodiments, and will not be described again in this embodiment.

[0098] For example, the inspection system may also include a ground monitoring terminal, which is set up at maintenance stations or mobile work vehicles along the overhead power transmission cable 200. It has a human-machine interface for receiving real-time data uploaded by the inspection equipment 100, including video images, equipment operating parameters and location information, and can perform visual monitoring and scheduling of inspection tasks.

[0099] Furthermore, the 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 the inspection equipment 100 between the ground and the overhead power transmission cable 200.

[0100] The inspection system provided in this application, by setting up an inspection device 100, has a configuration structure in which a counterweight mechanism 120 is used to position the overall center of gravity of the inspection device 100 below the overhead transmission cable 200. Furthermore, the overall center of gravity and the center of mass of the device body 110 are located on opposite sides of the contact point between the drive wheel 111 and the overhead transmission cable 200, respectively. This allows the inspection device 100 to be mounted on the overhead transmission cable 200 in an inclined posture. By ensuring that the inclination direction of the inspection device 100 is opposite to the skew direction caused by the spiral structure of the overhead transmission cable 200, and that the inclination angle can be adjusted by the weight of the counterweight mechanism 120 and its installation position, when the inspection device 100 is subjected to lateral forces and skews during its movement, the inclination posture can compensate for the skew angle, thereby preventing the skew angle from exceeding the safety threshold and causing the inspection device 100 to detach from the cable. This helps ensure the reliable suspension of the inspection device 100 and improves the stability of the inspection.

[0101] 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.
