[0002] Suspension power transmission line, especially 125kV or above high-voltage line, is the key component of the backbone of power grid. Therefore, the safe operation and maintenance of suspension power transmission line is directly related to the lifeline of national economy.

The traditional installation method relies on manual tower climbing or live working vehicle, which has high difficulty, high labor cost, high risk of live working and is prone to electric shock accidents. Currently, by carrying the electrical equipment required for maintenance on the unmanned aerial vehicle and mounting it on the suspension power transmission line, the efficiency and safety of line maintenance can be effectively improved.

[0003] For example, a solar power overhead line intelligent warning device without power-off installation and removal is disclosed in Chinese patent CN118587823B. The disclosure realizes the convenient hanging and buckling between the warning device and the power transmission line by a pair of clamping springs.

[0042] As shown in Figures 1 to 8 The hanging and unloading device for aerial power line maintenance assisted by a UAV according to the embodiment of the present application comprises a device body provided with an electrical equipment to be hung. In this embodiment, the electrical equipment to be hung is configured as a warning module 90. The warning module 90 is detachably connected below the device body. The device body is used to be easily arranged on the UAV in a vertical direction. The device body comprises a shell 10, a motor assembly, an electromagnetic clutch 30, a first transmission assembly, a second transmission assembly, a rechargeable battery 60, a control circuit 80 and a wireless communication module 81 fixed in the shell 10, and the device body further comprises a first clamping arm 11, a second clamping arm 12, an annular base 13, a photovoltaic module 70 and an irradiation sensor 71.

[0043] Specifically, the first clamping arm 11 is fixedly arranged at the top of the shell 10, and the second clamping arm 12 is linearly reciprocally arranged on the shell 10, so that the first clamping arm 11 and the second clamping arm 12 are close to or away from each other. The first clamping arm 11 and the second clamping arm 12 are close to each other to a preset position to form a closed area for clamping the cable. The first clamping arm 11 and the second clamping arm 12 are away from each other to a preset position to form an open area allowing the cable to enter and exit.

[0044] Specifically, the annular base 13 is rotatably arranged outside the housing 10, and the photovoltaic module 70 and the irradiation sensor 71 are arranged on the annular base 13.

[0045] To drive the second clamping arm 12 and the annular base 13, specifically, the motor assembly includes a motor body 21 and a speed reducer 22. The motor body 21 is used to provide rotary power. The output shaft of the motor body 21 is connected to the input side of the speed reducer 22, and the rotary power is increased through the speed reducer 22. The speed reducer 22 is provided with a first output shaft 201 and a second output shaft 202 for outputting rotary power. The first output shaft 201 is drivingly connected to the first transmission assembly through the electromagnetic clutch 30, and the first transmission assembly is drivingly connected to the second clamping arm 12 to drive the movement of the second clamping arm 12. The second output shaft 202 is drivingly connected to the second transmission assembly, and the second transmission assembly is drivingly connected to the annular base 13 to drive the rotation of the annular base 13.

[0046] To realize the operation of the mechanical structure, specifically, referring to Figure 5 the functional block diagram of the hanging and unloading device, the control circuit 80 is electrically connected to the photovoltaic module 70, the irradiation sensor 71 and the rechargeable battery 60 to control the charging of the rechargeable battery 60 by the photovoltaic module 70. The control circuit 80 is electrically connected to the motor assembly, the electromagnetic clutch 30 and the wireless communication module 81 to remotely control the first clamping arm 11, the second clamping arm 12 and the annular base 13.

[0047] To realize the maintenance of the power transmission line, specifically, the control circuit 80 is electrically connected to the warning module 90 to control the power supply of the rechargeable battery 60 to the warning module 90. It can be understood that the warning module 90 has a radar sensing unit and an audible and visual unit. After the device body is hung on the power transmission line, the radar sensing unit can sense the object close to it and control the audible and visual unit to issue audible and visual alarm for warning, thereby protecting the power transmission line. In other embodiments, the electrical equipment to be hung can also be other maintenance equipment of the power transmission line which needs to be operated by power.

[0048] For ease of understanding, it is worth noting that the working principle of the present embodiment is: referring to Figure 6 and Figure 7In the mounting process, the mounting and dismounting device is mounted and docked to the top of the unmanned aerial vehicle, and the operator remotely controls the unmanned aerial vehicle to move the mounting and dismounting device to the vicinity of the power transmission line. After completion, the operator sends a control instruction to the wireless communication module 81 through the remote controller to control the mounting and dismounting device. The control circuit 80 responds to the control instruction and configures the electromagnetic clutch 30 to the connected state, and then controls the motor assembly to move in a direction, drives the second clamping arm 12 away from the first clamping arm 11 through the electromagnetic clutch 30 and the first transmission assembly, and forms an open area that can be sleeved into the power transmission line. After the power transmission line is sleeved, the control circuit 80 responds to the control instruction and controls the motor assembly to reverse rotation, drives the second clamping arm 12 to approach the first clamping arm 11 through the electromagnetic clutch 30 and the second transmission assembly, so as to fix the power transmission line in the closed area formed by the clamping arms.

[0049] After the mounting is completed, the operator controls the electromagnetic clutch 30 to switch to the disconnected state, as shown in Figure 8 , the mounting and dismounting device is in the daily state, and the control circuit 80 controls the rotation of the motor assembly according to the irradiation sensor 71, so as to realize the rotation of the annular base 13 and the photovoltaic module 70, so that the photovoltaic module 70 is perpendicular to the current sunlight, thereby improving the photovoltaic power generation power.

[0050] In the dismounting process, the operator remotely controls the unmanned aerial vehicle to the lower side of the mounting and dismounting device, and the unmanned aerial vehicle is mounted and docked to the mounting and dismounting device. Further, the operator controls the electromagnetic clutch 30 to switch to the connected state through the remote control, and then controls the motor assembly to move, so that the open area formed by the clamping arms realizes the separation of the mounting and dismounting device and the power transmission cable.

[0051] In order to realize the stability of the mounting, the first transmission assembly of the embodiment specifically includes a screw rod 41. The screw rod 41 is mounted in the housing 10 through a bearing, so that the screw rod 41 can rotate relative to the housing 10. The first output shaft 201 is connected to one side of the electromagnetic clutch 30, and one end of the screw rod 41 is connected to the other side of the electromagnetic clutch 30. The second clamping arm 12 is arranged in the guide groove 101. The second clamping arm 12 is provided with a threaded hole 121 which is matched with the screw rod 41. When the electromagnetic clutch 30 is in the connected state, the first output shaft 201 drives the screw rod 41 to rotate, and the rotation of the screw rod 41 drives the second clamping arm 12 to move in the direction of approaching or moving away from the first clamping arm 11 along the guide groove 101. When the electromagnetic clutch 30 is in the disconnected state, the rotation of the first output shaft 201 is no longer transmitted to the screw rod 41.

[0052] To realize the stability of the posture of the warning module 90 and the photovoltaic module 70, the first clamping arm 11 and the second clamping arm 12 in the clamping state are positioned along the axial direction of the annular base 13, so that the annular base 13 can be stabilized in the vertical direction of the clamped power transmission line. Specifically, the second transmission assembly includes a first worm gear, a second worm gear, a central gear 53, an outer peripheral gear 54, and a toothed ring 55. The first worm gear is connected to the second output shaft 202, and the first worm gear and the second worm gear are engaged with each other. The second worm gear and the central gear 53 are linked through a rotating shaft. The toothed ring 55 is connected to the inner edge of the annular base 13. The outer peripheral gear 54 is provided with three, which are engaged with the central gear 53 and the toothed ring 55, respectively. The first clamping arm 11 and the second clamping arm 12 in the clamping state are coaxial with the second worm gear, the central gear 53, and the toothed ring 55. When the second output shaft 202 rotates, the central gear 53 in the vertical direction is driven to rotate through the cooperation of the first worm gear 51 and the second worm gear 52, and the rotation is then transmitted to the toothed ring 55 through the circumferential gear. The toothed ring 55 is arranged in the axial direction of the annular base 13, and the first clamping arm 11 is arranged above the second worm gear 52 in the axial direction. Therefore, when the first clamping arm 11 and the second clamping arm 12 are hung on the power transmission line, the rotation of the annular base 13 is kept in the vertical direction.

[0053] To realize the rotation of the annular base 13, the bottom of the housing 10 is provided with a circular base 14, and the outer edge of the circular base 14 is provided with an annular groove 141 facing outward. The annular groove 141 is provided with three. The inner edge of the annular base 13 is provided with an arc-shaped hanging arm 131, which is fitted in the annular groove 141, so that the arc-shaped hanging arm 131 slides along the circumferential direction of the annular groove 141, and the annular base 13 is further rotatably arranged outside the housing 10.

[0054] To realize the irradiation tracking, the outer edge of the annular base 13 is inclined downward relative to the radial direction. The photovoltaic module 70 is arranged in a half-annular region of the annular base 13, so that the photovoltaic module 70 is directed to one side of the annular base 13. The irradiation sensor 71 is provided with at least two, and the two irradiation sensors 71 are arranged on the circumferential two sides of the photovoltaic module 70, respectively. The control circuit 80 controls the rotation of the motor body 21 through the difference between the two irradiation sensors 71, so that the photovoltaic module 70 is perpendicular to the solar irradiation, thereby improving the efficiency of obtaining photovoltaic power, and further enabling the rechargeable battery 60 to maintain a sufficient power state, thereby providing power guarantee for the operation of the warning module 90.

[0055] To improve the photovoltaic utilization space of the annular base 13, the embodiment is specifically provided with three photovoltaic modules 70. Each photovoltaic module 70 is arranged at equal intervals along the circumferential direction, thereby improving the balance of irradiation acquisition.

[0056] In order to protect the power transmission line to be clamped, specifically, the first clamping arm 11 is provided with a semicircular first clamping part, the second clamping arm 12 is provided with a semicircular second clamping part, the first clamping part and the second clamping part are matched to form a circular ring, thereby forming a double-semicircular structure closed area, and the power transmission line contact surface pressure distribution is uniformized.

[0057] In order to protect the power transmission line to be clamped, specifically, the first clamping arm 11 and the second clamping arm 12 are respectively covered with an insulating outer sleeve. In use, the insulating outer sleeve is in contact with the power transmission line, which can improve the stability of clamping and prevent the line from being damaged.

[0058] The above embodiments mainly describe the basic principles, main features and advantages of the utility model. It should be understood by those skilled in the art that the utility model is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the utility model.
