[0038] When using a flying device to lift, install, dismantle, and assemble inspection equipment, maintenance personnel control the electromagnet to be de-energized and operate the flying device to bring the electromagnet and the adsorption component together.

[0052] 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.

[0053] 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.

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.

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.

[0056] 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.

[0057] As an important component of the power grid, power transmission lines are inspected using inspection equipment to ensure their safety and prevent damage.

[0058] In related technologies, since power transmission lines are located at high altitudes, a threaded connection is usually used to fix the drone and inspection equipment, and at least two maintenance personnel work together with the drone to hoist the equipment onto or off the power transmission line.

[0059] Specifically, during the hoisting and installation of the inspection equipment, ground-based maintenance personnel connect the drone to the inspection equipment via a threaded connection and operate the drone to move the inspection equipment toward the maintenance personnel at higher altitudes. The maintenance personnel at higher altitudes receive the inspection equipment, disassemble the equipment from the drone, and then place the inspection equipment on the power line. During the hoisting and disassembly of the inspection equipment, ground-based maintenance personnel operate the drone to move toward the maintenance personnel at higher altitudes. The maintenance personnel at higher altitudes connect the drone to the inspection equipment via a threaded connection, and then the ground-based maintenance personnel operate the drone again to move the inspection equipment toward the ground, detaching the inspection equipment from the inspection line. After the inspection equipment returns to the ground, the maintenance personnel disassemble the drone and the inspection equipment.

[0060] However, when hoisting, installing, and dismantling inspection equipment, two maintenance personnel are required to complete the disassembly and assembly operations between the drone and the inspection equipment. This requires the use of tools, making the operation cumbersome and inconvenient, resulting in low efficiency in loading and unloading the inspection equipment.

[0061] In view of this, embodiments of this application provide a hoisting and dismantling structure, a hoisting device, and an inspection system. The hoisting and dismantling structure includes a connecting component and a control component. The connecting component includes a first connecting member, a second connecting member, an electromagnet, and an adsorption component. The control component includes a control component and a detection component. The first connecting member is used to connect with the flying component, and the second connecting member is used to connect with the component to be hoisted. By setting the electromagnet on the first connecting member and the adsorption component on the second connecting member, the control component controls the electromagnet to switch between a power-off state and a power-on state, so that the electromagnet is magnetic when not energized and demagnetized when energized. The flying component can be a drone. Electromagnets with different adsorption forces can be selected adaptively according to the weight of the component to be hoisted. The hoisting component can be an inspection device, etc.

[0062] When using a flying device to lift, install, dismantle, and inspect equipment, maintenance personnel control the electromagnet to be de-energized and operate the flying device to bring the electromagnet and the adsorption unit together. This allows the electromagnet's attraction to magnetically connect the flying device and the inspection equipment. Alternatively, the control unit can energize the electromagnet to detach it from the adsorption unit, allowing disassembly. A detection unit checks the connection between the electromagnet and the adsorption unit, enabling maintenance personnel to operate the flying device based on their connection status. This ensures the inspection equipment can be placed on or detached from the power line by the flying device. Thus, the lifting and dismantling structure provided in this embodiment eliminates the need for tools, allowing a single maintenance personnel to easily assemble and disassemble the flying device and the equipment to be lifted.

[0063] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0064] See Figures 1 to 6 The hoisting and disassembly structure 100 provided in this application embodiment includes a connecting component 110 and a control component 120. The connecting component 110 includes a first connecting member 111, a second connecting member 112, an electromagnet member 114, and an adsorption member 115. The first connecting member 111 is used to connect with the flying component, and the second connecting member 112 is used to connect with the component to be hoisted. The electromagnet member 114 is disposed on the first connecting member 111, and the adsorption member 115 is disposed on the second connecting member 112.

[0065] The control component 120 includes a control element 121 and a detection element 122. The control element 121 is used to control the electromagnet element 114 to switch between a power-off state and a power-on state. In the power-off state, when the electromagnet element 114 is driven by the flying element and is at least partially opposite to the adsorption element 115, it is magnetically connected to the adsorption element 115. In the power-on state, the electromagnet element 114 is disconnected from the adsorption element 115. The detection element 122 is used to detect whether the electromagnet element 114 is connected to the adsorption element 115.

[0066] It should be noted that the flying component in this application embodiment can be a drone, and the hoisting and disassembly structure 100 can be applied in power line inspection scenarios. The component to be hoisted can be an inspection device 200 for detecting the status of the transmission line 300, such as a detection device equipped with cameras, sensors, and other components, used to inspect the wear, corrosion, and connection point conditions of the transmission line 300. The component to be hoisted can also be a small tool or spare part used for the maintenance of the transmission line 300, such as a wrench for tightening bolts or a replacement insulator. Furthermore, the hoisting and disassembly structure 100 can be applied in other fields such as construction, and the component to be hoisted can also be building materials, maintenance tools, etc. As long as the weight of the component to be hoisted is within the load-bearing range of the flying component and the attraction range of the electromagnet component 114, this application embodiment does not impose any limitations on this.

[0067] The first connector 111 in the connecting assembly 110 can be fixedly connected to the flying component by means of bolts, clips or welding. The first connector 111 can be designed according to the structural adaptability of the flying component, such as being plate-shaped, frame-shaped or rod-shaped, to ensure stable assembly with the flying component. The second connector 112 is used to connect with the component to be lifted. It can adopt a connection method adapted to the structure of the component to be lifted. For example, the second connector 112 is fixed to the component to be lifted by bolts, so that the component to be lifted can be stably suspended below the second connector 112.

[0068] Electromagnet 114 is an energized demagnetizing electromagnet. It is magnetic when not energized and demagnetized when energized. A control element 121 controls the switching between the energized and de-energized states of electromagnet 114. The adsorption element 115 can be made of magnetically conductive materials such as iron, cobalt, or nickel, enabling it to form a stable magnetic attraction with electromagnet 114.

[0069] In practice, when the electromagnet 114 is energized, the flying component drives the electromagnet 114 to face the adsorption component 115, so that the magnetic attraction force of the electromagnet 114 can effectively act on the adsorption component 115 to form a stable magnetic connection.

[0070] The detection component 122 is set to detect whether the electromagnet component 114 and the adsorption component 115 are connected. For example, the connection status information of the electromagnet component 114 and the adsorption component 115 can be provided to the maintenance personnel through prompt sound or light flashing, so that the maintenance personnel can control the timing of the operation of the flying component to lift the component to be lifted according to the connection status of the electromagnet component 114 and the adsorption component 115.

[0071] Specifically, taking the inspection equipment 200 as an example, the process of hoisting and installing the inspection equipment 200 on the power transmission line 300 by means of the hoisting and disassembly structure 100 and the flying component is explained. First, the electromagnet 114 is de-energized by the control unit 121, making it magnetic. Maintenance personnel operate the flying device to magnetically connect the electromagnet 114 to the adsorption unit 115. When the detection unit 122 detects the connection between the electromagnet 114 and the adsorption unit 115, the light changes from flashing to off, indicating that the connection between the flying device and the inspection equipment 200 is complete. Then, the maintenance personnel operate the flying device to move the inspection equipment 200 towards the power line 300, allowing it to be mounted on the power line 300. Finally, the maintenance personnel control the electromagnet 114 to be energized by the control unit 121, demagnetizing it and detaching it from the adsorption unit 115. When the detection unit 122 detects the detachment of the electromagnet 114 from the adsorption unit 115, the light changes from off to flashing, indicating that the disassembly of the flying device and the inspection equipment 200 is complete, and the flying device can then be operated to return to the ground.

[0072] Furthermore, the process of hoisting and disassembling the inspection equipment 200 from the power transmission line 300 using the hoisting and disassembly structure 100 in conjunction with the flying component can refer to the above process, and will not be described again in this embodiment.

[0073] In summary, the hoisting and disassembly structure 100 provided in this application embodiment can adaptably select electromagnets 114 with different suction forces according to the different weights of the parts to be hoisted, and the parts to be hoisted can be inspection equipment 200, etc. When the inspection equipment 200 is hoisted, installed, or disassembled using the flying device, the maintenance personnel control the electromagnet 114 to be de-energized via the control unit 121, and operate the flying device to bring the electromagnet 114 and the adsorption unit 115 together, so that the attraction force of the electromagnet 114 can act on the adsorption unit 115 to form a magnetic connection, thus connecting the flying device and the inspection equipment 200. Alternatively, the control unit 121 can be used to energize the electromagnet 114, causing the electromagnet 114 to detach from the adsorption unit 115, thus disassembling the flying device and the inspection equipment 200. The detection unit 122 is used to detect whether the electromagnet 114 and the adsorption unit 115 are connected, so that the maintenance personnel can operate the flying device according to the connection status of the electromagnet 114 and the adsorption unit 115, ensuring that the inspection equipment 200 can be placed on or detached from the power transmission line 300 under the action of the flying device. Thus, with the hoisting and disassembly structure 100 provided in this application embodiment, no disassembly or assembly tools are needed, and a single maintenance personnel can complete the disassembly and assembly between the flying component and the component to be hoisted, making disassembly and assembly more convenient.

[0074] See Figure 1 , Figure 3 and Figure 4In some embodiments, one of the first connector 111 and the second connector 112 has a guide portion 113. The guide portion 113 includes a placement section 1131 and a guide section 1132 arranged sequentially. One of the electromagnet 114 and the adsorption member 115 is disposed within the placement section 1131. The guide section 1132 forms a guide area. The guide section 1132 is configured to guide the other of the electromagnet 114 and the adsorption member 115 to be opposite to one of the electromagnet 114 and the adsorption member 115 during the descent of the flying component when the flying component moves the electromagnet 114 above the adsorption member 115, so that the other of the electromagnet 114 and the adsorption member 115 is partially located in the guide area.

[0075] Specifically, the guide portion 113 can be disposed on the first connector 111 or on the second connector 112, and this application embodiment does not limit this. In addition, red or other markings can be applied to the surface of the adsorption member 115 for easy identification, making it easier to position the other part of the electromagnet 114 and the adsorption member 115 within the guide area.

[0076] By placing one of the electromagnet 114 and the adsorption component 115 within the placement section 1131, the component maintains a stable reference position during docking, providing a clear target landing point for the approach of the other component.

[0077] By setting the guide section 1132, when the flying component moves the electromagnet 114 above the adsorption component 115, if the other part of the electromagnet 114 and the adsorption component 115 enters the guide area, the guide section 1132 will continuously guide the component during the descent of the flying component. If the guide section 113 is located in the first connector 111 and the placement section 1131 contains the electromagnet 114, the edge of the adsorption component 115 will contact the inner wall of the guide section 1132 when it descends with the flying component. Under the combined action of gravity and the downward force of the flying component, it will slide along the inner wall towards the placement section 1131, gradually adjusting its position to be opposite to the electromagnet 114 in the placement section 1131. If the guide section 113 is located in the second connector 112 and the placement section 1131 contains the adsorption component 115, the electromagnet 114 will be constrained by the guide section 1132 during descent. The deviation will be corrected by the limiting effect of the inner wall, and finally a corresponding positional relationship will be formed with the adsorption component 115 in the placement section 1131.

[0078] In this way, there is no need to precisely control the three-dimensional movement of the flying component. The flying component drives the electromagnet component 114 to be directly above the adsorption component 115. Through the vertical guidance of the guide section 1132, the descent action of the flying component is combined with the alignment process of the component. Even if there is a slight deviation in the horizontal direction of the flying component, accurate docking can be achieved through the continuous guidance provided by the guide section 1132 during the descent process, which further improves the fault tolerance and stability of the operation.

[0079] It should be noted that the other part of the electromagnet 114 and the adsorption component 115 is located within the guide area. That is, the area of ​​the overlapping portion of the other part of the electromagnet 114 and the adsorption component 115 and the guide section 1132 facing each other can be set according to the actual situation. For example, the area of ​​the overlapping portion can account for 60%-70% of the area of ​​the other part of the electromagnet 114 and the adsorption component 115. As long as the inner wall of the guide section 1132 can provide effective lateral constraint on the other part of the electromagnet 114 and the adsorption component 115, the position can be gradually corrected by contour guidance.

[0080] In summary, the design of the guide section 113 in this embodiment of the application helps to reduce the requirements for the precision of operation and maintenance personnel. In complex environments such as high-altitude wind resistance, it can reduce the probability of docking failure and improve the connection efficiency between the flying part and the part to be hoisted.

[0081] See Figure 1 and Figure 2 For example, the guide segment 1132 is funnel-shaped, and a guide region is formed between the small diameter end and the large diameter end of the guide segment 1132. The small diameter end is connected to the placement segment 1131.

[0082] In this way, the cross-sectional area of ​​the guide region gradually shrinks from the large diameter end to the small diameter end, forming a smoothly transitioning conical inner wall. This reduces the mechanical wear of the electromagnet 114 and the adsorption component 115 during the docking process. It also ensures that the components can still be guided smoothly within the offset range through the gradual spatial constraint, further reducing the dependence on the control precision of the flying component and making the docking of the electromagnet 114 and the adsorption component 115 more stable and efficient.

[0083] See Figure 2 Furthermore, the guide section 1132 is provided with an observation port 1133, which is used to face the camera of the flying component.

[0084] Thus, during the process of the flying component cooperating with the hoisting and disassembly structure 100 to hoist the component to be hoisted, the maintenance personnel can observe the position and status of the component to be hoisted through the observation port 1133 via the camera of the flying component, ensuring that the component to be hoisted can be hoisted to the target position normally.

[0085] For example, the item to be hoisted is an inspection device 200. The inspection device 200 is installed on the power transmission line 300 by clamping the upper and lower parts of the power transmission line 300. During the operation of the flying device to move the inspection device 200 toward the power transmission line 300, the maintenance personnel can observe through the observation port 1133 that after the upper clamping part of the inspection device 200 contacts the power transmission line 300, they can remotely control the lower clamping part of the inspection device 200 to rise and press the power transmission line 300. When it is confirmed again through the observation port 1133 by the camera of the flying device that the lower clamping part has pressed the power transmission line, the electromagnet part 114 and the adsorption part 115 can be detached by the control unit 121.

[0086] The observation port 1133 can be a rectangular hole, a circular hole, an elliptical hole, etc., and this application embodiment does not limit it.

[0087] Reference Figure 5 In some examples, the detection element 122 includes a switch part 1221 and an alarm part 1222; the switch part 1221 is disposed on the electromagnet part 114; the alarm part 1222, the switch part 1221 and the electromagnet part 114 are sequentially electrically connected to form an electrical circuit; the switch part 1221 is configured to open to disconnect the electrical circuit when the electromagnet part 114 is in a de-energized state to magnetically connect with the adsorption member 115, so that the alarm part 1222 stops alarming; and to close to electrically connect the electrical circuit when the electromagnet part 114 is in a energized state to detach from the adsorption member 115, so that the alarm part 1222 is energized and alarms.

[0088] In this way, by combining mechanical triggering and circuit response, real-time monitoring of the connection status between electromagnet 114 and adsorption component 115 is achieved, and the alarm status is associated with the magnetic adsorption status. The operation results can be intuitively fed back without additional control logic, simplifying the detection structure. This ensures that maintenance personnel can accurately judge the docking status in complex operating environments, further improving the safety and reliability of the operation.

[0089] When the alarm unit 1222 is powered on, it sends an alarm signal (such as at least one of continuous beeping and flashing light) to notify the maintenance personnel that the electromagnet 114 and the adsorption unit 115 have been successfully detached.

[0090] Reference Figure 6 In some examples, the control component 120 also includes a remote control 123, which is communicatively connected to the control component 121. The remote control 123 is used to control the control component 121 to switch the electromagnet component 114 between a power-off state and a power-on state based on the detection information of the detection component 122.

[0091] Specifically, the remote control unit 123 is typically equipped with operation buttons or a touch interface, allowing maintenance personnel to send switching commands to the control unit 121 based on the connection status detection information of the electromagnet 114 and the adsorption unit 115 obtained from the detection unit 122. This allows the electromagnet 114 to switch between a power-off state and a power-on state. In this way, maintenance personnel can complete the state switching operation without close contact with the equipment, achieving remote control and making operation more convenient.

[0092] The remote control unit 123 can be a wireless remote control or a control terminal with an integrated wireless communication module, which can establish a stable communication connection with the control unit 121. The communication connection can be Bluetooth, radio frequency or other wireless transmission methods suitable for outdoor operations, ensuring that control signals and status information can be transmitted between the two in real time.

[0093] See Figure 4 In some embodiments, the control unit 121 includes a communication circuit board section 1211 and a power supply section 1212; the communication circuit board section 1211 is communicatively connected to the electromagnet 114 and is used to control the electromagnet 114 to switch between a power-off state and a power-on state; the power supply section 1212 is electrically connected to the communication circuit board section 1211 and is used to supply power to the communication circuit board section 1211.

[0094] The communication circuit board 1211 integrates a microprocessor, a wireless communication module, and a control interface. It establishes a communication connection with the electromagnet 114 via wires or wireless signals, and can receive external control commands (such as switching signals from the remote control 123). Based on these commands, it generates corresponding control signals to regulate the switching of the electromagnet 114 between a power-off state and a power-on state. In the power-off state, the communication circuit board 1211 cuts off the power supply to the electromagnet 114. In the power-on state, the communication circuit board 1211 connects the power supply circuit, energizing and demagnetizing the electromagnet 114.

[0095] The power supply unit 1212 and the communication circuit board unit 1211 can be electrically connected via an electrical connector or wire. The power supply unit 1212 can be a rechargeable battery, lithium battery pack or other portable power source to provide a stable operating voltage and current to the communication circuit board unit 1211, ensuring the normal operation of all functions of the communication circuit board unit 1211.

[0096] For example, the control element 121 is disposed on the first connector 111, and the control component 120 further includes a signal transmission element 124, which is connected to the first connector 111, and the control element 121 is communicatively connected to the remote control element 123 through the signal transmission element 124.

[0097] In this way, reliable communication between the control unit 121 and the remote control unit 123 is achieved through the signal transmission unit 124, which can ensure the real-time transmission of control commands.

[0098] When maintenance personnel operate the remote control unit 123 to control the electromagnet 114 from a powered-on state to a powered-off state, or from a powered-off state to a powered-on state, through the control unit 121, the signal transmission unit 124 is used to convert the operation command issued by the remote control unit 123 into an electrical signal and transmit it to the control unit 121, so that the control unit 121 can complete the control of the electromagnet 114.

[0099] In a specific example, the signal transmission component 124 includes a housing portion 1241 and an antenna 1242 disposed within the housing portion 1241; the housing portion 1241 is connected to the first connector 111, and the control component 121 is communicatively connected to the remote control component 123 via the antenna 1242.

[0100] In this way, the wireless signal emitted by the remote control component 123 can be received through the antenna 1242, converted into an electrical signal and transmitted to the control component 121, so that the control component 121 controls the electromagnet component 114 to switch between the power-off state and the power-on state.

[0101] The housing 1241 may be designed with a streamlined structure or have a hollowed-out area in the signal transmission and reception direction (the hollowed-out area may be covered with a wave-transparent material) to avoid obstructing the signal of the antenna 1242 and to ensure that the antenna 1242 can transmit signals to the remote control 123 without obstruction.

[0102] See Figures 1 to 4 In some examples, the first connector 111 includes a first connecting portion 1111, a receiving portion 1112, and a second connecting portion 1113 arranged sequentially; the first connecting portion 1111 is used to connect with the flight component, the receiving portion 1112 has a receiving cavity 1114, the control component 121 is located in the receiving cavity 1114, and the second connecting portion 1113 is connected to the electromagnet component 114.

[0103] Thus, through the segmented and modular design, the first connector 111 can be stably connected to the flight component, and can provide a protective space for the control component 121 and support the electromagnet component 114, which is conducive to improving the integration and reliability of the hoisting and disassembly structure.

[0104] The first connecting part 1111 is located at the end of the first connecting member 111. The first connecting part 1111 can be stably connected to the flight component by means of bolt fastening, snap locking or flange docking, so as to ensure that the flight component can drive the entire first connecting member 111 and subsequent components to move synchronously.

[0105] The receiving part 1112 is located between the first connecting part 1111 and the second connecting part 1113. The receiving cavity 1114 of the receiving part 1112 is used to receive the control component 121. The receiving part 1112 can be made of aluminum alloy material, which plays the role of dustproof, waterproof and collision-proof, and avoids the control component 121 from being damaged by external environmental interference during hoisting.

[0106] The second connecting part 1113 is located on the side of the receiving part 1112 away from the first connecting part 1111. The second connecting part 1113 may be provided with a stud, slot or other structure, and be fixed in cooperation with the corresponding interface of the electromagnet 114 so as to be directly connected to the electromagnet 114. Alternatively, it can be understood that when the guide part 113 is provided on the first connecting part 111, the second connecting part 1113 can be connected to the electromagnet 114 through the guide part 113. For example, the second connecting part 1113 has a stud, the placement section 1131 of the guide part 113 has a through hole, the electromagnet 114 has a threaded hole, and the stud passes through the through hole and connects with the threaded hole to ensure that the position of the electromagnet 114 corresponds to the adsorption part 115 on the second connecting part 112.

[0107] See Figures 2 to 7 In some embodiments, the second connector 112 includes a support portion 1121 and two third connector portions 1122; the support portion 1121 is connected to the adsorption member 115; the two third connector portions 1122 are spaced apart on the side of the support portion 1121 away from the adsorption member 115, and both third connector portions 1122 are connected to the support portion 1121, and both third connector portions 1122 are used to connect to the object to be lifted.

[0108] Thus, the second connector 112 is securely connected to the adsorption component 115 via the support part 1121, providing a reliable foundation for magnetic docking. At the same time, the two spaced third connectors 1122 ensure stable load-bearing of the component to be lifted, effectively distributing weight and reducing swaying. Especially during high-altitude lifting, this helps improve the balance and safety of the component to be lifted.

[0109] The third connecting part 1122 and the supporting part 1121 can be fixed by integral molding, welding, or bolting to form a stable load-bearing structure. The supporting part 1121 can be a plate-like structure, and the adsorption component 115 can be fixed to the supporting part 1121 by welding, bolting, or gluing; or, when the guide part 113 is set on the second connecting part 112, the supporting part 1121 can be connected to the adsorption component 115 through the guide part 113. For example, the supporting part 1121 has a stud, the placement section 1131 of the guide part 113 has a through hole, and the adsorption component 115 has a threaded hole. The stud passes through the through hole and connects with the threaded hole to ensure that the position of the adsorption component 115 corresponds to the electromagnet component 114 on the first connecting part 111. The third connecting part 1122 can be an L-shaped plate, which is connected to the part to be lifted by bolting.

[0110] This application also provides a hoisting device, including a flying component and the hoisting and disassembly structure 100 in any of the above embodiments.

[0111] The flying component is connected to the first connecting member 111 of the hoisting and dismantling structure 100. The second connecting member 112 of the hoisting and dismantling structure 100 is used to connect to the component to be hoisted. The flying component is configured such that when the control member 121 of the hoisting and dismantling structure 100 controls the electromagnet 114 set on the first connecting member 111 to be de-energized, the electromagnet 114 is driven to magnetically connect with the adsorption member 115 set on the second connecting member 112, so as to connect the first connecting member 111 and the second connecting member 112, and drive the component to be hoisted to the target position.

[0112] The overall structure and working principle of the hoisting and dismantling structure 100 are the same as those in the previous embodiments, and will not be described again in this embodiment.

[0113] For example, the item to be hoisted can be the inspection equipment 200. It is understood that when the inspection equipment 200 is hoisted and installed on the power transmission line 300 by the hoisting device, the target location is the power transmission line 300; when the inspection equipment 200 is hoisted and disassembled from the power transmission line 300 by the hoisting device, the target location is the ground.

[0114] See Figure 6 In some examples, the flying component is communicatively connected to the remote control unit 123 of the hoisting and disassembly structure 100. The remote control unit 123 is used to control the flight attitude of the flying component. The remote control unit 123 is configured to control the electromagnet 114 to be de-energized before controlling the flying component to magnetically connect the electromagnet 114 with the adsorption component 115, and to control the electromagnet 114 to be energized after the component to be hoisted to the target position, thereby disengaging the first connector 111 and the second connector 112.

[0115] Thus, the remote control unit 123, as the core component integrating flight control and electromagnet state regulation, can achieve multi-step collaborative control by using a unified operating terminal, reducing the complexity of equipment operation.

[0116] Specifically, before the controlled flying component drives the electromagnet 114 to magnetically connect with the adsorption component 115, the remote control component 123 sends a command to the control component 121, causing the control component 121 to switch the electromagnet 114 to a de-energized state, ensuring that the electromagnet 114 retains its magnetism to meet the magnetic attraction requirements. At this time, maintenance personnel can use the remote control component 123 to control the flying component to adjust its attitude, gradually bringing the electromagnet 114 closer to the adsorption component 115 until the two complete the magnetic connection. After the component to be hoisted is lifted to the target position by the flying component, the maintenance personnel send a command to the control component 121 again through the remote control component 123. The control component 121 then controls the electromagnet 114 to switch to an energized state, demagnetizing the electromagnet 114, thereby achieving the separation of the first connecting component 111 from the second connecting component 112.

[0117] See Figure 7 This application also provides an inspection system, including an inspection device 200 and a hoisting device as described in the above embodiments; the inspection device 200 is connected to the second connector 112 in the hoisting and disassembly structure 100 of the hoisting device, and the hoisting device is used to hang the inspection device 200 on the power transmission line 300 or to detach the inspection device 200 from the power transmission line 300.

[0118] The overall structure and working principle of the hoisting device are the same as those in the previous embodiments, and will not be described again in this embodiment.

[0119] In practice, the inspection equipment 200 has a built-in wireless communication module, which can establish a communication connection with the remote control unit 123. Thus, maintenance personnel can send detection commands to the inspection equipment 200 via the remote control unit 123. Upon receiving the command, the inspection equipment 200 will activate its camera to capture images of the power transmission line 300, control sensors to collect line parameters (such as temperature and vibration data), and transmit the data back to the remote control unit 123 in real time via the communication module, allowing maintenance personnel to view the detection results on the display screen of the remote control unit 123.

[0120] In some embodiments, the two third connecting portions 1122 of the second connector 112 are arranged sequentially along the extension direction of the power transmission line 300, and the guide portion 113 of the hoisting and disassembly structure 100 is disposed on the second connector 112. The guide portion 113 and the two adjacent sides of the two third connecting portions 1122 are respectively coated with a first marking layer and a second marking layer; or, the guide portion 113 is disposed on the first connector 111, and the outer side of the guide portion 113 is coated with a third marking layer and a fourth marking layer. One of the two third connecting portions 1122 is correspondingly coated with a third marking layer, and the other is correspondingly coated with a fourth marking layer.

[0121] Thus, the setting of the marking layer can provide visual reference for high-altitude operations, reduce alignment errors caused by distance and viewing angle limitations, and help improve the orientation accuracy of the inspection equipment 200 when it is hung on the power transmission line 300.

[0122] It is understood that the extension direction of the transmission line 300 is the axial direction of the transmission line 300. When the inspection equipment 200 is hung on the transmission line 300, the two third connecting parts 1122 are arranged sequentially along the extension direction of the transmission line 300.

[0123] When the guide portion 113 of the hoisting and dismantling structure 100 is mounted on the second connector 112, a first marking layer and a second marking layer are respectively coated on the adjacent sides of the guide portion 113 and the two third connectors 1122. These two marking layers can be designed with easily identifiable visual distinctions, such as different colors or textures. Thus, when the flying component hoists and installs the inspection equipment 200 onto the power transmission line 300, maintenance personnel can observe through the camera of the flying component to ensure that the first marking layer and the second marking layer are sequentially set along the extension direction of the power transmission line 300, thereby determining the accurate hoisting orientation of the component on the power transmission line 300.

[0124] When the guide part 113 is installed on the first connector 111, a third marking layer and a fourth marking layer are coated on the outside of the guide part 113. Simultaneously, two third connectors 1122 correspond to these two marking layers, one corresponding to the third marking layer and the other to the fourth marking layer. Thus, as the flying component moves the first connector 111 closer to the second connector 112, maintenance personnel can observe the correspondence between the two marking layers on the guide part 113 and the third connector 1122, and then operate the electromagnet 114 and the magnetic attraction component 115 to magnetically connect them. Then, when the inspection equipment 200 is hoisted and installed onto the power transmission line 300 by the flying component, maintenance personnel can observe through the camera on the flying component to ensure that the third and fourth marking layers on the guide part 113 are sequentially set along the extension direction of the power transmission line 300. This allows them to determine the accurate hoisting position of the component on the power transmission line 300, ensuring that the orientation of the inspection equipment 200 meets the installation requirements.

[0125] 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.
