Description

Technical Field

[0001] This invention relates to the field of power grid maintenance equipment technology, and in particular to a drone-mounted phase spacer installation system. Background Technology

[0002] During the operation of overhead transmission lines, in order to limit the relative sway amplitude between different phase conductors, maintain safe phase-to-phase distances, and reduce the impact of factors such as galloping and wind deflection on the safe operation of transmission lines, it is usually necessary to install phase spacers between adjacent phase conductors. Phase spacers can form mechanical constraints between different phase conductors, thereby improving the operational stability of transmission lines under complex weather conditions.

[0003] The installation of phase-to-phase spacers currently relies on manual tower climbing, following the conductor, or using insulated bucket trucks. These methods generally suffer from high labor intensity for workers, high risks associated with working at heights, low construction efficiency, and stringent requirements for site terrain and workspace. Especially for transmission lines crossing rivers, valleys, roads, and other complex terrain areas, conventional construction equipment struggles to reach suitable working locations, further increasing the difficulty of phase-to-phase spacer installation.

[0004] With the development of drone-based hoisting technology, using drones to carry phase spacers into the target installation area provides a new technical approach to reduce the risks of manual high-altitude operations. However, phase spacers themselves have a certain length and weight, and both ends need to be reliably clamped to the power lines and cables. During drone hoisting, they are easily affected by wind, swaying, and changes in installation attitude. If only simple slings are used for hoisting, it is not only difficult to ensure accurate positioning of the phase spacers, but also there is the problem that the hoisting device is not easy to reliably separate from the phase spacers after installation.

[0005] Furthermore, in cases of abnormal situations such as jamming of the drone hoisting equipment, failure of the unhooking mechanism, or failure of the connection parts to separate normally, the lack of reliable redundancy release measures may lead to a continuous connection between the drone and the installed phase spacers or power transmission lines, thereby increasing the risk of drone loss of control, equipment damage, or even affecting the safe operation of the power transmission lines.

[0006] Therefore, it is necessary to provide a phase spacer installation system that can be hoisted by drones, can remotely drive clamping fixtures to clamp the line cables, can actively detach after installation, and can achieve redundant release through fuse in abnormal situations. Summary of the Invention

[0007] The purpose of this invention is to provide a drone-mounted phase spacer installation system to solve the problems of high risk of manual high-altitude operation, low construction efficiency, difficulty in positioning and clamping phase spacers during the existing phase spacer installation process, and difficulty in reliably detaching the hoisting system from the phase spacers after installation.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention discloses a drone-mounted phase spacer installation system, comprising an insulated main lifting beam disposed at the bottom of the drone. The insulated main lifting beam is connected to insulated connecting rods via several fixing hardware. A phase spacer body is disposed at the end of each of the insulated connecting rods away from the fixing hardware. Clamping fixtures are respectively disposed at the ends of the phase spacer bodies, and the clamping fixtures are driven to perform clamping operations by a through-type linear motor. A disengagement mechanism and a fusion mechanism are disposed between the insulated connecting rods and the phase spacer bodies. The insulated connecting rods and the through-type linear motor are connected together by a connecting rope. A controller electrically connected to the through-type linear motor, the disengagement mechanism, and the fusion mechanism is disposed on one side of the insulated connecting rod. The controller is equipped with a receiving antenna for receiving remote control signals.

[0009] Furthermore, the clamping fixture includes an inclined wire fixing hardware, one end of which is bolted to the main body of the phase spacer bar, and the other end is integrally formed with a downwardly extending line cable fixing clamping block. The bottom of the inclined wire fixing hardware is also integrally formed with a downwardly extending fixing plate, and a clamping screw is threadedly connected to the center of the fixing plate. One end of the clamping screw is provided with a line cable clamping slider that cooperates with the line cable fixing clamping block, and the other end is pluggably connected to the through-type linear motor.

[0010] Furthermore, the tilt angle of the inclined wire fixing hardware is 1° to 89°, and it is made of aluminum alloy profile; The inclined wire fixing hardware has a hollow right-angled triangular structure, and the cable fixing clamp block and fixing plate are located on its inclined surface. The right-angled surface is set together with the main body of the phase spacer.

[0011] Furthermore, the inclined wire fastener has a connecting threaded hole that matches the bolt.

[0012] Furthermore, the nut inside the through-type linear motor is fast-locked using a balancing machine.

[0013] Furthermore, the fixing plate is provided with a plurality of locking components at one end near the through-type linear motor, and the end face of the through-type linear motor is provided with locking holes that match the locking components.

[0014] Furthermore, the inclined wire fixing hardware has an inwardly extending limiting groove at one end away from the line cable fixing clamping block, and the through-type linear motor is provided with a matching limiting pin.

[0015] Furthermore, the unhooking mechanism includes a main electric unhooker disposed between the insulating connecting rod and the phase spacer body, and the main electric unhooker is connected to the controller via an unhooker cable.

[0016] Furthermore, the fuse mechanism includes a main fuse mechanism and a secondary fuse mechanism; The main fuse mechanism includes a main fuse rope connecting the main electric unhooker and the insulating connecting rod. A main fuse is installed on the main fuse rope, and the main fuse is connected to the controller through a main fuse cable. The auxiliary fuse mechanism includes an auxiliary fuse mounted on the connecting rope, and the auxiliary fuse is connected to the controller via an auxiliary fuse cable.

[0017] Furthermore, the through-type linear motor is connected to the controller via a cable.

[0018] Compared with the prior art, the beneficial technical effects of the present invention are as follows: This invention utilizes a drone equipped with an insulated hoisting structure to transport phase-to-phase spacer bars to the target line location. This reduces the need for personnel to climb towers, access lines, and move at high altitudes on conductors, thus mitigating the risks of high-altitude construction and adapting to construction environments that are difficult for conventional large-scale equipment to reach, such as mountainous areas, rivers, valleys, and road crossings. The insulated hoisting main beam and insulated connecting rods form the hoisting support structure for the phase-to-phase spacer bars, maintaining insulation between the drone and the spacer bars to be installed, improving electrical safety during drone hoisting operations near transmission lines. Clamping fixtures driven by through-type linear motors are installed at both ends of the phase-to-phase spacer bars. These fixtures can be remotely controlled to drive the clamping screws, causing the cable clamping sliders and cable fixing clamps to cooperate, achieving mechanical clamping of the cable and reducing direct manual operation, thus increasing the degree of automation in installation. The inclined fixing hardware can be arranged according to the actual spatial position of the phase conductors and the installation posture of the phase-to-phase spacer bars, facilitating alignment between the clamping fixtures and the cable and improving adaptability to different line layout conditions. The through-type linear motor and clamping fixture employ a pluggable, lockable, and limit-positioning connection structure. This ensures stable power transmission during installation and facilitates separation of the drive device from the clamping fixture after the spacer bars are clamped. The clamping fixture remains on the line with the spacer bars, while the drive device is retrieved with the drone. An electric release mechanism allows for proactive disengagement of the lifting connection after the spacer bars are installed, enabling rapid separation between the drone's lifting structure and the installed spacer bars, improving installation and evacuation efficiency. A multi-stage safety release structure, comprised of a main fuse mechanism and a secondary fuse mechanism, allows for emergency separation by remotely fusing the corresponding connecting components when normal release fails or the lifting connection malfunctions. This reduces the risk of damage to the drone, installation equipment, and power lines due to continuous entanglement. The controller connects to the clamping drive mechanism, release mechanism, and fuse mechanism, and receives remote control signals via an antenna. It allows for centralized control of clamping, release, and emergency fuse actions according to the installation workflow, facilitating a complete remote drone installation process.

[0019] In summary, this invention enables UAV hoisting, remote clamping, active detachment, and emergency release of phase spacers under abnormal conditions, reducing the risks of manual high-altitude operations and improving installation efficiency and operational safety.

[0022] Example 1 like Figure 1-5 As shown, a drone-mounted phase spacer installation system includes an insulated hoisting main beam 1 located at the bottom of the drone. The insulated hoisting main beam 1 serves as the main load-bearing component between the entire phase spacer hoisting system and the drone, and is used to bear the weight of the phase spacer body 4, clamping fixture 5, and related drive and control components during the installation process.

[0023] The insulated hoisting main beam 1 is equipped with insulated connecting rods 3 via several fixing hardware 2. The fixing hardware 2 is installed at corresponding positions on the insulated hoisting main beam 1 to reliably connect the insulated connecting rods 3 to the insulated hoisting main beam 1. The insulated connecting rods 3 are made of insulating material or have insulation properties that meet the requirements of power transmission line operations, so as to form a certain insulating isolation distance between the UAV and the equipment to be installed.

[0024] Several insulating connecting rods 3 have a phase-spacer bar body 4 at the end furthest from the fixing hardware 2. The number and installation position of the insulating connecting rods 3 can be rationally selected based on the length, structural form, and hoisting stability requirements of the phase-spacer bar body 4. During hoisting, the phase-spacer bar body 4 is positioned below the UAV, and the insulating connecting rods 3 bear the main hoisting load of the phase-spacer bar body 4. Depending on the overall structural center of gravity, a counterweight 8 can be installed on the insulating hoisting main beam 1 if necessary. The counterweight 8 adjusts the center of gravity of the hoisting system, ensuring the phase-spacer bar body 4 maintains a relatively stable attitude during flight transport and installation.

[0025] The phase spacer body 4 is equipped with clamping fixtures 5 at its ends. The clamping fixtures 5 are used to connect the ends of the phase spacer body 4 to the corresponding line cables. The clamping fixtures 5 are driven by a through-type linear motor 6 to perform the clamping operation, so that the clamping fixtures 5 can automatically clamp the line cables after the UAV hovers at the predetermined installation position.

[0026] like Figures 3 to 5 As shown, the clamping fixture 5 includes an inclined wire fixing hardware 501. One end of the inclined wire fixing hardware 501 is bolted to the phase spacer body 4, and the other end is integrally formed with a downwardly extending cable fixing clamping block 502. The inclined wire fixing hardware 501 has a connecting threaded hole 511 that matches the bolt. The mounting bolt can engage with the connecting threaded hole 511 to fix the inclined wire fixing hardware 501 to the end of the phase spacer body 4. The bottom of the inclined wire fixing hardware 501 also has an integrally formed downwardly extending fixing plate 505. A clamping screw 504 is threadedly connected to the center of the fixing plate 505. One end of the clamping screw 504 is provided with a cable clamping slider 503 that engages with the cable fixing clamping block 502, and the other end is pluggably connected to the through-type linear motor 6. The cable clamping slider 503 can move closer to or further away from the cable fixing clamping block 502 as the clamping screw 504 moves. During installation, the cable to be clamped is located between the cable fixing clamping block 502 and the cable clamping slider 503. When the cable clamping slider 503 moves towards the cable fixing clamping block 502, the distance between them gradually decreases, thereby clamping the cable; when the cable clamping slider 503 moves away from the cable fixing clamping block 502, the clamping space increases, so that the cable can enter the clamping fixture 5.

[0027] The tilt angle of the inclined wire fixing hardware 501 is 1° to 89°. By setting the tilt angle, the clamping position of the line cable of the clamping fixture 5 can be more easily aligned with the target line cable according to the positional relationship of adjacent phase conductors and the actual installation posture.

[0028] The inclined wire fixing hardware 501 is made of aluminum alloy profile.

[0029] The inclined wire fixing hardware 501 has a hollow right-angled triangular structure. The cable fixing clamp block 502 and the fixing plate 505 are located on its inclined surface. The right-angled surface is set together with the phase spacer body 4. By installing different right-angled surfaces with the phase spacer body 4, its inclined surface is tilted downward, which meets the necessary condition for the through linear motor 6 to disengage.

[0030] The lead screw nut inside the through-type linear motor 6 is a quick-lock nut 507 using a balancing machine. The quick-lock nut 507 enables rapid connection and release between the through-type linear motor 6 and the clamping screw 504, ensuring power transmission during clamping and facilitating separation of the through-type linear motor 6 from the clamping fixture 5 after clamping. The through-type linear motor 6 drives the clamping screw 504 to move axially, thereby driving the cable clamping slider 503 to complete the clamping action.

[0031] The fixed plate 505 has several locking elements 508 near one end of the through-type linear motor 6, and the end face of the through-type linear motor 6 has locking holes 506 that match the locking elements 508. When the through-type linear motor 6 is assembled with the clamping fixture 5, the locking elements 508 can enter the corresponding locking holes 506 to restrict the relative position between the through-type linear motor 6 and the fixed plate 505, and prevent the through-type linear motor 6 from rotating or shifting undesirably during the clamping process.

[0032] In this embodiment, the locking element 508 and the locking hole 506 can be a commercially available YE-304NO mini insert electric drawer lock, or a locker lock, electric cabinet lock, or other electrically controlled locking device capable of achieving the same locking and unlocking functions. The YE-304NO electric lock is only used to illustrate one possible form of the locking element 508 in this embodiment and does not constitute a limitation on the specific model, size, working voltage, lock tongue structure, or drive form of the locking element 508. In practical applications, other electric locking elements with equivalent locking functions can be selected according to the structural dimensions of the through-type linear motor 6 and the fixed plate 505, the locking load, and the control method. During installation, the lock body of the electrically controlled insert locking element can be fixed to the fixed plate 505 by screws, bolts, snap-fit ​​structures, or other detachable connection methods, and the movement direction of the lock tongue should be adapted to the position of the corresponding locking hole 506. The shape and size of the locking hole 506 are set according to the shape of the locking tongue, so that the locking tongue can enter the locking hole 506 after it extends and form a reliable limit, and can smoothly exit the locking hole 506 after the unlocking action is performed. Thus, the locking member 508 and the locking hole 506 together constitute the electrically controllable unlockable locking structure between the through linear motor 6 and the clamping fixture 5.

[0033] The inclined wire fixing hardware 501 has an inwardly extending limiting groove 509 at one end away from the line cable fixing clamping block 502, and the through-type linear motor 6 is provided with a matching limiting pin 510. When the through-type linear motor 6 is connected to the clamping fixture 5, the limiting pin 510 enters the limiting groove 509, and the position of the through-type linear motor 6 relative to the inclined wire fixing hardware 501 is further restricted by the cooperation between the limiting pin 510 and the limiting groove 509.

[0034] Therefore, a reliable detachable drive connection can be formed between the through-type linear motor 6 and the clamping fixture 5 through the clamping screw 504, the balancing machine quick lock nut 507, the locking element 508, the locking hole 506, the limiting groove 509, and the limiting pin 510. During the clamping operation, the through-type linear motor 6 can stably provide driving force to the clamping screw 504; after the clamping operation is completed, the corresponding connection can be released according to the predetermined action, so that the through-type linear motor 6 and the clamping fixture 5 can be separated from each other.

[0035] A disengagement mechanism and a fusion mechanism are provided between the insulating connecting rod 3 and the phase spacer body 4 for disengagement. The insulating connecting rod 3 and the through-type linear motor 6 are connected together by a connecting rope 13. The connecting rope 13 is used to provide auxiliary suspension and constraint for the through-type linear motor 6 during installation, preventing the through-type linear motor 6 from falling uncontrollably during connection or separation from the clamping fixture 5. A controller 9 is provided on one side of the insulating connecting rod 3, which is electrically connected to the through-type linear motor 6, the disengagement mechanism, and the fusion mechanism. The controller 9 is equipped with a receiving antenna 10 for receiving remote control signals.

[0036] The unhooking mechanism includes a main electric unhooker 7 disposed between the insulating connecting rod 3 and the phase spacer body 4. The main electric unhooker 7 is connected to the controller 9 via an unhooker cable 701. After the phase spacer body 4 has completed the line clamping, the controller 9 can send an action command to the main electric unhooker 7 according to the remote control signal, so that the main electric unhooker 7 performs the unhooking action to release the main hoisting connection between the phase spacer body 4 and the insulating connecting rod 3.

[0037] The fuse mechanism includes a main fuse mechanism and a secondary fuse mechanism.

[0038] The main fuse mechanism includes a main fuse rope 11 connecting the main electric release device 7 and the insulating connecting rod 3. A main fuse 12 is mounted on the main fuse rope 11, and the main fuse 12 is connected to the controller 9 via a main fuse cable 1201. During normal installation, the main electric release device 7 can be used to actively separate the phase spacer body 4 from the insulating connecting rod 3. When the main electric release device 7 fails to complete the normal release according to the control command due to mechanical jamming, electrical fault, or other reasons, the controller 9 can control the main fuse 12 to disconnect the main fuse rope 11, thereby creating an emergency release path for the main hoisting connection.

[0039] The auxiliary fuse mechanism includes an auxiliary fuse 14 mounted on the connecting rope 13, which is connected to the controller 9 via an auxiliary fuse cable 1401. When the through-type linear motor 6 and the clamping fixture 5 cannot be properly separated due to jamming or other abnormalities, or when the connecting rope 13 remains entangled with the installed components during the drone's withdrawal, the auxiliary fuse 14 can be activated to achieve emergency disconnection of the corresponding connection part of the connecting rope 13.

[0040] The through-type linear motor 6 is connected to the controller 9 via cable 15. The controller 9 controls the operation of the through-type linear motor 6. The main electric unhooking device 7 is connected to the controller 9 via unhooking device cable 701; the main fuse 12 is connected to the controller 9 via main fuse cable 1201; and the auxiliary fuse 14 is connected to the controller 9 via auxiliary fuse cable 1401. This forms a clamping, unhooking, and emergency fuse control structure with the controller 9 as its core.

[0041] The working process of this invention is as follows: Before the operation begins, the insulated hoisting main beam 1 is installed at the bottom of the drone, and the main body 4 of the phase spacer to be installed is hoisted below the insulated hoisting main beam 1 using the fixing hardware 2 and the insulated connecting rod 3. The through-type linear motor 6 is connected to the clamping screw 504 of the corresponding clamping fixture 5, and the locking part 508 is engaged with the locking hole 506, and the limiting pin 510 is engaged with the limiting groove 509 to complete the installation of the clamping drive mechanism. At the same time, the connection status of the main electric release device 7, the main fuse 12, the auxiliary fuse 14, and each cable is checked.

[0042] Subsequently, the drone carrying the entire installation system takes off and flies to the vicinity of the line to be installed under the control of the operator. By adjusting the position and attitude of the drone, the clamping fixtures 5 at both ends of the phase spacer body 4 are brought close to the corresponding line cables, and the line cables are brought into the clamping area formed between the line cable fixing clamping block 502 and the line cable clamping slider 503.

[0043] After the target cable enters the clamping area, the remote end sends a clamping control signal to the receiving antenna 10, and the controller 9 controls the through-type linear motor 6 to operate. The through-type linear motor 6 drives the clamping screw 504 to move, and the clamping screw 504 further drives the cable clamping slider 503 to move towards the cable fixing clamping block 502 until the cable is reliably clamped. After both ends of the phase spacer body 4 are clamped, the phase spacer body 4 is reliably installed between the corresponding cables through the clamping fixture 5. At this time, the through-type linear motor 6 can be disconnected from the clamping fixture 5, so that the through-type linear motor 6 remains on the UAV hoisting side and is ready for recovery, while the clamping fixture 5 and the phase spacer body 4 remain on the line.

[0044] Subsequently, the remote end sends a release command to the controller 9, which in turn controls the main electric release device 7 to disengage the insulating connecting rod 3 from the already installed phase spacer body 4. After the release is complete, the UAV carries the insulated hoisting main beam 1, the insulated connecting rod 3, and the corresponding drive and control components away from the line installation area.

[0045] If the main electric unhooking device 7 fails to unhook normally, the main fuse 12 can be activated by the controller 9 to disconnect the main fusible rope 11, thereby releasing the main hoisting connection. If the through-type linear motor 6 or the connecting rope 13 is still abnormally connected to the line-side structure, the auxiliary fuse 14 can be activated by the controller 9 according to the actual situation to achieve emergency release of the connecting rope 13, allowing the UAV to detach from the line-side equipment.

[0046] Example 2 like Figure 6 As shown, this embodiment provides another arrangement of the UAV-mounted phase spacer installation system. The main structure and working principle of this embodiment are the same as those of Embodiment 1, and it also includes an insulated hoisting main beam 1, fixing hardware 2, insulated connecting rod 3, phase spacer body 4, clamping fixture 5, through-type linear motor 6, unhooking mechanism, fusing mechanism, and controller 9.

[0047] In this embodiment, the insulated hoisting main beam 1 is set horizontally below the UAV, and two sets of insulated connecting rods 3 are respectively set at different positions of the insulated hoisting main beam 1 through fixing hardware 2. The main body 4 of the phase spacer is located below the insulated hoisting main beam 1 and is hoisted by the insulated connecting rods 3 on both sides.

[0048] The relatively stable hoisting support formed by the insulating connecting rods 3 on both sides can keep the phase spacer body 4 in a relatively stable horizontal or predetermined installation posture during the flight of the UAV, thereby reducing the possibility of the phase spacer body 4 swinging around a single hoisting point.

[0049] Clamping fixtures 5 are installed at both ends of the phase spacer body 4, and a through-type linear motor 6 is correspondingly installed at each clamping fixture 5. After the UAV transports the phase spacer body 4 to the target line, the overall position of the UAV can be adjusted so that the clamping fixtures 5 at both ends are aligned with the corresponding line cables.

[0050] After the line cable enters the clamping area of ​​the clamping fixture 5, the controller 9 controls the through linear motor 6 to move, so that the line cable clamping sliders 503 at both ends move toward the corresponding line cable fixing clamping blocks 502, thereby achieving clamping and fixing between the two ends of the phase spacer body 4 and the line cable.

[0051] After installation, following the method described in Example 1, the through-type linear motor 6 is separated from the clamping fixture 5, and then the connection between the insulating connecting rod 3 and the phase spacer body 4 is released by the main electric release device 7, allowing the UAV hoisting part to separate from the phase spacer body 4 and be removed. If an abnormality occurs during the normal detachment process, emergency release can also be performed through the main fuse 12 and the auxiliary fuse 14.

[0052] This embodiment allows for adaptive configuration based on different specifications of phase spacers, different line spacings, and different UAV hoisting conditions by changing the relative arrangement of the insulating connecting rod 3 and the phase spacer body 4.

[0053] Example 3 like Figure 7 As shown, this embodiment provides another arrangement of a UAV-mounted phase spacer installation system. This embodiment has the same basic components as Embodiments 1 and 2, the main difference being the spatial arrangement of the UAV, insulated hoisting main beam 1, insulated connecting rod 3, and phase spacer body 4, which adapts to their respective construction postures.

[0054] In this embodiment, the UAV is supported by an insulated hoisting main beam 1 from one side of the phase spacer body 4. An insulated connecting rod 3 is connected between the insulated hoisting main beam 1 and the phase spacer body 4 to maintain a safe distance between the UAV and the phase spacer body 4.

[0055] Clamping fixtures 5 are respectively installed at both ends of the phase spacer body 4, and a through-type linear motor 6 is installed on the clamping fixture 5. The UAV adjusts its flight attitude and hovering position to bring the phase spacer body 4 close to the installation area in an attitude adapted to the spatial position of the phase conductor on site.

[0056] After the clamping fixtures 5 at both ends of the phase spacer body 4 are aligned with the corresponding line cables, the controller 9 controls the through linear motor 6 to perform the clamping action, so that the line cable clamping slider 503 cooperates with the line cable fixing clamping block 502 to clamp the line cable in the clamping fixture 5.

[0057] After clamping is completed, the drive connection between the through-type linear motor 6 and the clamping fixture 5 is released through the separable structure between them. Then, the main electric unhooker 7 is controlled to perform the unhooking action, thereby disconnecting the insulating connecting rod 3 and the phase spacer body 4. The UAV then carries away the insulated hoisting main beam 1, the insulating connecting rod 3, and the through-type linear motor 6, as well as other retrievable components, while the phase spacer body 4 and the clamping fixtures 5 at both ends remain installed between the line cables.

[0058] In the event of an abnormality in the disengagement or separation of the drive mechanism, the main fuse 12 and the auxiliary fuse 14 can be used for emergency release to ensure that the UAV can detach from the line-side structure in a timely manner.

[0059] The spatial arrangement shown in this embodiment provides another hoisting posture option for the installation of spacers between phases under different orientations, height differences, or site space conditions.

[0060] The overall working principle of this invention is as follows: First, the main body 4 of the phase spacer bar to be installed is suspended below the UAV using the insulated hoisting main beam 1, fixing hardware 2, and insulated connecting rod 3, and the through-type linear motor 6 is connected to the clamping fixture 5. The controller 9 receives control commands sent by ground or remote equipment through the receiving antenna 10.

[0061] After the drone takes off, it transports the phase spacer body 4 to the two phase line cables to be installed, and adjusts the position and attitude of the drone to align the clamping fixtures 5 at both ends of the phase spacer body 4 with the corresponding line cables.

[0062] After the line cable enters between the line cable fixing clamping block 502 and the line cable clamping slider 503, the controller 9 starts the through-type linear motor 6. The through-type linear motor 6 drives the clamping screw 504 to move, which in turn moves the line cable clamping slider 503 towards the line cable fixing clamping block 502, reliably clamping the line cable and realizing the fixed connection between the phase spacer body 4 and the line cable.

[0063] After the phase spacer body 4 is installed, the through-type linear motor 6 is disconnected from the clamping fixture 5. Subsequently, the controller 9 sends a release command to the main electric release device 7, causing the insulating connecting rod 3 to separate from the phase spacer body 4, allowing the UAV to carry the recyclable components of the hoisting system away.

[0064] When the main electric unhooker 7 fails to complete the normal unhooking, the controller 9 controls the main fuse 12 to cut off the main fuse rope 11, thereby achieving the emergency release of the main hoisting connection; when the connecting rope 13 or the through linear motor 6 cannot be properly separated from the line side structure, the controller 9 controls the auxiliary fuse 14 to achieve the emergency disconnection of the connecting rope 13.

[0065] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
