Description

Technical Field

[0001] This invention relates to the field of spacer technology, and more specifically to a spacer clamp. Background Technology

[0002] With the expansion of my country's power distribution network overhead lines and technological upgrades, the mass per unit length of conductors, the mass of fittings, and the diameter have increased significantly, leading to a substantial increase in the risk of line galloping. This can cause conductor cross-contact, phase-to-phase short circuits, and serious accidents such as line tripping and power outages, threatening the safe and stable operation of the power grid. To prevent cross-contact, spacers are needed to fix the distance between conductors. Due to their good insulation and mechanical strength, spacers can effectively support different phase conductors and restrain them from each other, making them highly effective in suppressing conductor galloping. They have become a routine anti-galloping measure for power companies.

[0003] In the existing technology, the common structure of spacer bars is that they are supported by clamps from two directions and hung in a conventional structure. When fixing or disassembling them, most devices used to connect spacer bars and wires generally use arc-shaped notches for fixing. This semi-open clamping design of arc-shaped notches is prone to the wires moving relative to the notches after the clamps loosen, eventually causing the wires to detach from the notches and fall off, which poses a great safety hazard. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the installation of spacer bars is difficult to fix the wires and clamps in all directions through the conventional semi-open clamping structure with notches. During manual disassembly or in a natural state, the clamps are prone to slippage after loosening, and the risk resistance is insufficient. The purpose is to design a spacer bar clamp to solve the above-mentioned technical problems.

[0005] The present invention provides the following apparatus: A spacer bar clamp includes a connecting end for connecting to a spacer bar and a clamping end for connecting to a conductor. The clamping end includes a first clamp for fixing one side of the conductor, a second clamp for clamping and fixing the other side of the conductor, and a connector for connecting the first clamp and the second clamp. The clamp is rotated to fit the other side of the conductor. When the first clamp and the second clamp are fitted together, the conductor is located between the first clamp and the second clamp, and the first clamp and the second clamp are fixedly connected by the connector.

[0006] Furthermore, the first clip has a recessed first opening on the side near the second clip, and the second clip has a recessed second opening on the side near the first clip corresponding to the first opening. When the first clip and the second clip are fitted together, the first opening and the second opening form a connection port on the outer side of the circumference of the wire.

[0007] Furthermore, a rotating shaft is horizontally arranged at the end of the first clamping piece away from the connecting end, and the second clamping piece is rotatably arranged at one end of the first clamping piece with the rotating shaft as the fulcrum; a first rotating hole is provided at the end of the first clamping piece away from the connecting strip corresponding to the rotating shaft; a redundant block is provided protruding at the end of the second clamping piece corresponding to the rotating shaft, and a second rotating hole for adapting the rotating shaft is provided through the side of the redundant block, with the first rotating hole aligned with the second rotating hole, and the rotating shaft is inserted into the first rotating hole at one end, passes through the second rotating hole, and finally exits through the first rotating hole at the other end.

[0008] Furthermore, the connector includes a snap-fit ​​protrusion disposed at the end of the second clamping piece away from the rotation axis and a snap-fit ​​buckle disposed on the lower side of the first clamping piece; the snap-fit ​​buckle includes a square compartment with an open top and a horizontally movable stop bar, the top opening of the square compartment extending to connect to the inner wall of one side near the clamping end; when the first clamping piece and the second clamping piece are in contact with each other, the snap-fit ​​protrusion is inserted into the square compartment through the side opening, and the lower part of the snap-fit ​​protrusion abuts against the stop bar.

[0009] Furthermore, a limit pin is provided on the inner wall of the square compartment near the connecting end. A hole is provided in the middle of the stop bar corresponding to the limit pin. The limit pin is inserted through the hole and fixedly connected to the inner wall of the square compartment. The stop bar slides along the axial direction of the limit pin. Movable slots are provided horizontally on the side wall of the square compartment corresponding to both ends of the stop bar. The two ends of the stop bar are inserted into the movable slots on both sides and move horizontally along the movable slots on both sides.

[0010] Furthermore, a spring is fitted onto one end of the limiting pin near the square compartment, with one end of the spring abutting against the stop bar and the other end abutting against the inner wall of the square compartment.

[0011] Furthermore, the top of the snap-fit ​​protrusion is set as a chamfered bevel, and the bottom is set as a right angle.

[0012] Furthermore, a pull rod and a collar are fixedly installed on the stop bar. The pull rod is horizontally positioned on one side of the collar, and the collar is fixedly fitted onto the stop bar.

[0013] Furthermore, the two pull members extend towards the connecting end, and the ends of the two pull members away from the stop bar are connected to each other to form a pull ring.

[0014] Furthermore, a sliding buckle is vertically provided on the side of the connecting end, and a limiting hole is provided through the sliding buckle corresponding to the pull member; the middle part of the pull rod is slidably disposed in the limiting hole.

[0015] Furthermore, the portion of the pull rod located on the side of the sliding buckle near the connecting end is extended and bent.

[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. The present invention uses a first clamp to initially position the conductor, and then uses a second clamp to rotate to the other side of the conductor and cooperate with the first clamp to clamp the conductor in the middle. The first clamp and the second clamp are fixed by a combined connector, thus completing the installation of the spacer and fixing the conductor and the clamp in all directions. This reduces the possibility of the clamp loosening, losing its clamping function on the conductor, or slipping, and improves the spacer's ability to withstand risks.

[0017] 2. This invention is applicable to the quick disassembly of spacer bar clamps by drones. When it is necessary to replace an aging spacer bar, the drone can release the connector of the clamp, releasing only the second clamping piece. The clamp loses its clamping state, but the spacer bar can still stay on the wire briefly by relying on the first clamping piece. This avoids the spacer bar being in an unstable state during disassembly, making it easier for the drone to separate the spacer bar from the wire and transport it back to the ground for inspection and maintenance. This is convenient, quick, and improves work efficiency, while reducing the danger of manual disassembly and reducing the occurrence of spacer bars falling. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0021] Example 1: like Figures 1-4 As shown, a spacer bar clamp includes a connecting end 1 for connecting to a spacer bar 24 and a clamping end 2 for connecting to a conductor. The connecting end 1 and the clamping end 2 are integrally formed structures or fixedly connected by welding to ensure the stability of the connection to withstand the tension and vibration during the operation of the conductor. The clamping end 2 includes a first clamping piece 3 for fitting one side of the conductor and a second clamping piece 4 that cooperates with the first clamping piece 3 to clamp the other side of the conductor. Both the first clamping piece 3 and the second clamping piece 4 are arc-shaped structures adapted to the shape of the conductor. The curvature is designed according to the outer diameter specifications of common conductors to ensure a close fit with the surface of the conductor. When the first clamping piece 3 and the second clamping piece 4 are fitted together, the conductor is wrapped in the clamping space formed between the first clamping piece 3 and the second clamping piece 4. The first clamping piece 3 and the second clamping piece 4 are detachably fixedly connected by a connector, which can be opened and closed according to installation and maintenance needs to control the connection between the first clamping piece 3 and the second clamping piece 4 and the overall clamping effect of the clamp.

[0022] Specifically, the first clamping piece 3 has a recessed first clamping opening 7 on the side near the second clamping piece 4, and the second clamping piece 4 has a recessed second clamping opening 8 on the side near the first clamping piece 3 corresponding to the first clamping opening 7. The length direction of the first clamping opening 7 is consistent with that of the second clamping piece 4, and the length direction of the second clamping opening 8 is consistent with that of the first clamping piece 3. The curvature of the recesses of both is adapted to the outer circumference curvature of the conductor, which enhances the clamping stability of the conductor and prevents the spacer 24 from sliding or rotating on the conductor. When the first clamping piece 3 and the second clamping piece 4 are in contact with each other, the first clamping opening 7 and the second clamping opening 8 are precisely aligned to form a complete connection. The inner wall of the connection is fully in contact with the outer circumference of the conductor, which increases the contact area between the first clamping piece 3, the second clamping piece 4 and the conductor. By replacing point contact or line contact with surface contact, the clamping pressure is effectively dispersed, the clamping firmness is improved, and the conductor is always kept in a stable installation position.

[0023] Preferably, the first clamp 3 is provided with a filling block with an arc-shaped notch at the first clamp 7, and the second clamp 4 is also provided with a filling block with a corresponding arc-shaped notch at the second clamp 8. The filling block is made of hard rubber and is adapted according to the outer diameter of the conductor to ensure a good fit with the surface of the conductor. When the first clamp 7 and the second clamp 8 are precisely aligned and connected to form a complete connection, the filling block plays a role in insulating and fixing the conductor, ensuring the relative fixation of the spacer 24 and the conductor, reducing friction caused by relative movement at the connection and damage to the conductor's protective layer, and preventing the conductors at both ends from forming a phase-to-phase short circuit through the spacer 24, which would cause the line to trip and lose power.

[0024] Specifically, the first clamping piece 3 and the second clamping piece 4 adopt a rotary connection structure, enabling the opening and closing operation of the connector to quickly clamp the wire; the end of the first clamping piece 3 away from the connecting end 1 is horizontally provided with a rotating shaft 9, which is a cylindrical metal rod, and its axis is parallel to the width direction of the first clamping piece 3; the second clamping piece 4 is rotatably connected to one end of the first clamping piece 3 with the rotating shaft 9 as the fulcrum, so that the second clamping piece 4 can rotate around the rotating shaft 9 from 0 degrees to 180 degrees, realizing the opening and closing of the clamping end 2; Specifically, to achieve the installation and fixation of the rotating shaft 9, the end of the first clamping piece 3 away from the connecting end 1 has two symmetrically distributed first rotating holes 10 corresponding to the rotating shaft 9. The two first rotating holes 10 are coaxially arranged, and their diameters are adapted to the outer diameter of the rotating shaft 9. The end of the second clamping piece 4 corresponding to the rotating shaft 9 has a protruding extension block 11, which is a rectangular block structure. Figure 5 As shown, the side of the extension block 11 is provided with a second rotating hole 12 adapted to the rotating shaft 9. The diameter of the second rotating hole 12 matches the outer diameter of the rotating shaft 9. The extension block 11 of the second clamping piece 4 is placed between the two first rotating holes 10, so that the first rotating hole 10 and the second rotating hole 12 are aligned. The rotating shaft 9 is inserted into the first rotating hole 10 at one end, passes through the first first rotating hole 10 and the second rotating hole 12 in sequence, and finally comes out from the first rotating hole 10 at the other end. The two ends of the rotating shaft 9 are limited by interference fit to prevent the rotating shaft 9 from moving axially during use, and to ensure that the second clamping piece 4 can rotate flexibly and stably around the rotating shaft 9.

[0025] Specifically, the connector includes a snap-fit ​​protrusion 13 located at the end of the second clamping piece 4 away from the rotation axis 9, and a snap-fit ​​buckle 14 corresponding to the snap-fit ​​protrusion 13 located on the side of the first clamping piece 3. The snap-fit ​​protrusion 13 is a wedge-shaped block structure, integrally formed with the second clamping piece 4, wherein the end away from the second clamping piece 4 is provided with an inclined surface to facilitate guiding the snap-fit ​​protrusion 13 to be accurately inserted into the snap-fit ​​buckle 14 for connection. The snap-fit ​​buckle 14 includes a square compartment 15 with a top opening, and a stop bar 16 horizontally movable within the square compartment 15. The square compartment 15 is a hollow rectangular cavity structure, fixedly connected to the first clamping piece 3. The top opening of the square compartment 15 communicates with the inner wall of the side near the clamping end 2, forming a channel for the snap-fit ​​protrusion 13 to be inserted. The stop bar 16 is a cylindrical rod, the length of which is the same as that of the square compartment. The internal width of the square compartment 15 is adapted to allow horizontal movement within the compartment. When the first clamping piece 3 and the second clamping piece 4 are fixed, the second clamping piece 4 is rotated to move towards the first clamping piece 3 until the first clamping piece 3 and the second clamping piece 4 are fully engaged. At this time, the snap-fit ​​protrusion 13 enters the square compartment 15 from the top opening and moves towards the side opening. During this process, the inclined surface of the snap-fit ​​protrusion 13 contacts and abuts against the stop bar 16, pushing the stop bar 16 to move horizontally away from the clamping end 2. After the snap-fit ​​protrusion 13 is fully inserted into the square compartment 15, the stop bar 16 returns to its original position towards the snap-fit ​​protrusion 13 until the top of the stop bar 16 abuts against the bottom of the snap-fit ​​protrusion 13, thereby limiting and fixing the snap-fit ​​protrusion 13 and firmly connecting the first clamping piece 3 and the second clamping piece 4.

[0026] Specifically, such as Figure 6 As shown, a limit pin 17 is fixedly installed on the inner wall of the square compartment 15 near the connecting end 1. One end of the limit pin 17 is screwed to the inner wall of the square compartment 15. A insertion hole 18 is provided in the middle of the stop rod 16 corresponding to the limit pin 17. The diameter of the insertion hole 18 is slightly larger than the outer diameter of the limit pin 17. The limit pin 17 is inserted through the insertion hole 18 and fixedly connected to the inner wall of the square compartment 15. The stop rod 16 slides along the axial direction of the pin rod of the limit pin 17. The limit pin 17 restricts the range of motion of the stop rod 16, preventing the stop rod 16 from moving too far. During the process, if a deviation occurs, the side wall of the square compartment 15 is provided with movable slots 19 at both ends of the stop bar 16. The length direction is consistent with the width direction of the square compartment 15. The two ends of the stop bar 16 pass through the movable slots 19 on both sides and extend to the outside of the square compartment 15. The two ends of the stop bar 16 can move horizontally along the movable slots 19 on both sides. The movable slots 19 cooperate with the limit pins 17 to limit the movement trajectory of the stop bar 16, ensuring that the stop bar 16 can only move horizontally within the set range and avoid jamming.

[0027] Specifically, a spring 20 is fitted onto one end of the limiting pin 17 near the square chamber 15. One end of the spring 20 abuts against the side of the stop rod 16, and the other end abuts against the inner wall of the square chamber 15. When the stop rod 16 moves horizontally under the pressure of the locking protrusion 13, the spring 20 is compressed and generates an elastic restoring force. When the locking protrusion 13 is fully inserted into the square chamber 15, the pressure of the locking protrusion 13 on the stop rod 16 disappears, and the spring 20 pushes the stop rod 16 to move under the action of the elastic restoring force, so that the stop rod 16 quickly resets and abuts against the bottom of the locking protrusion 13, realizing automatic limiting and fixing. The spring 20 is provided for the timeliness and reliability of the stop rod 16's reset, and can also buffer the impact between the stop rod 16 and the locking protrusion 13 through elastic force.

[0028] Preferably, the top end of the snap-fit ​​protrusion 13 is set as a chamfered bevel, and the bottom end is set as a right angle. During the installation and clamping process, the stop bar 16 is automatically moved horizontally away from the snap-fit ​​protrusion 13 by the chamfered bevel until the stop bar 16 moves along the chamfered bevel to the bottom of the bevel and conforms to abut the end of the snap-fit ​​protrusion 13, so as to realize the automatic alignment and automatic adaptation of the connector.

[0029] Specifically, a pull rod 21 and a collar 22 are fixedly installed on the stop rod 16. The two pull rods 21 are symmetrically distributed at both ends of the stop rod 16. The collar 22 is a ring structure with an inner diameter that matches the outer diameter of the stop rod 16. The collar 22 is fixedly sleeved on the stop rod 16 to prevent relative sliding between the collar 22 and the stop rod 16. The extension direction of the pull rod 21 is perpendicular to the length direction of the stop rod 16. By pulling the pull rod 21, the collar 22 and the stop rod 16 can be moved together, thereby realizing the horizontal sliding of the stop rod 16 and releasing the restriction on the locking protrusion 13.

[0030] Specifically, both pull rods 21 extend towards the connecting end 1, and the ends of the two pull rods 21 away from the stop rod 16 are fixed to each other by welding to form an annular pull ring 23. The pull ring 23 allows the clamp to be pulled by one hand, which simultaneously moves the two pull rods 21 and the stop rod 16. Compared with a single pull rod 21, this operation is more labor-saving and the force is evenly distributed, preventing the stop rod 16 from tilting and jamming due to force on one side, and ensuring smooth operation.

[0031] Specifically, the spacer clamp also includes a sliding buckle 6, which is vertically fixed to the side of the clamp body. A limiting hole 5 is provided through the sliding buckle 6 corresponding to the pull rod 21. The diameter of the limiting hole 5 is slightly larger than the outer diameter of the pull rod 21 to prevent friction when the pull rod 21 moves within the top hole. The middle part of the pull rod 21 slides through the limiting hole 5. The limiting hole 5 restricts the movement of the pull rod 21, ensuring that the pull rod 21 only... It can move along the axis of the limiting hole 5, preventing the pull rod 21 from deviating or shaking during the pulling process, ensuring that the pull rod 21 can smoothly drive the stop rod 16 to move, and reducing frictional wear and jamming.

[0032] Preferably, the pull rod 21 is bent and inclined at the part of the sliding buckle 6 near the connecting end 1, with the bending point precisely located at the limiting hole 5. This divides the pull rod 21 into two sections: one section is horizontally set and connected to the collar 22, and the other section extends inclinedly towards the connecting end 1. The bending design of the pull rod 21 makes the position of the pull ring 23 closer to the connecting end 1, which conforms to ergonomic operating habits. When installing or removing the spacer bar clamp, the operator can more easily grasp the pull ring 23 and apply pulling force. At the same time, the inclined pull rod 21 can disperse the direction of pulling force and reduce the friction between the pull rod 21 and the limiting hole 5, making the pulling operation more effortless and smooth. Specifically, the part of the pull rod 21 on the side of the sliding buckle 6 near the connecting end 1 is extended and bent, and the middle part of the pull ring 23 is also inclined, with an angle range of 90 degrees to 180 degrees. The preferred inclination angle is 45 degrees near the connecting end 1, with the corner point being the limiting hole 5 of the sliding buckle 6.

[0033] Specifically, the assembly and use process of the spacer clamp is as follows: First, the operator pulls the pull ring 23, causing the pull rod 21 and the stop rod 16 to move downwards, compressing the spring 20 and disengaging the stop rod 16 from the opening channel of the square compartment 15; then, the second clamping plate 4 is rotated around the rotating axis 9 to open the clamping end 2, placing the wire into the first clamping opening 7 of the first clamping plate 3; subsequently, the second clamping plate 4 is rotated in the opposite direction to bring it closer to the first clamping plate 3, with the second clamping opening 8 of the second clamping plate 4 adhering to the surface of the wire, while the engaging protrusion 13 is gradually inserted into the square compartment 15; when the first clamping plate 3 and the second clamping plate 4 are fully engaged, the pull ring 23 is released, and the spring 20 returns to its elastic state. Under the action of the compound force, the stop bar 16 is pushed to reset, and the stop bar 16 abuts against the lower part of the snap-fit ​​protrusion 13, realizing the fixed connection between the first clamp 3 and the second clamp 4, and the wire is firmly clamped in the connection port; finally, the clamp is fixedly connected to the spacer bar 24 through the connection end 1, completing the entire installation process; when it is necessary to disassemble or adjust, simply pull the pull ring 23 to drive the stop bar 16 to release the limit on the snap-fit ​​protrusion 13, the second clamp 4 opens the connection port around the rotation axis 9, and finally remove the clamp, and further remove the connecting part of the connection end 1 used to connect the end of the spacer bar 24, disconnecting the spacer bar 24 from the clamp, which facilitates the storage and portable handling of the spacer bar 24 and the clamp.

[0034] Specifically, the overall assembly and use process of the spacer clamp is as follows: First, the device is assembled by passing the rotating shaft 9 through the first rotating hole 10 of the first clamping piece 3 and the second rotating hole 12 of the extension block 11 of the second clamping piece 4 to complete the rotational connection between the first clamping piece 3 and the second clamping piece 4; then, the spring 20 is sleeved on the limiting pin 17, and the stop rod 16 is installed on the limiting pin 17 through the insertion hole 18, ensuring that both ends of the stop rod 16 pass through the movable strip hole 19 of the square compartment 15; next, the collar 22 is fixedly sleeved on both ends of the stop rod 16, so that the pull rod 21 and the collar 22 are connected as one unit, and the pull rod 21 is passed through the limiting hole 5 of the sliding buckle 6. Finally, the ends of the two pull rods 21 are fixedly connected to form a pull ring 23. After assembly, when clamping the wire at the installation site, the operator first pulls the pull ring 23, causing the pull rod 21 and the stop rod 16 to move downwards. The spring 20 is compressed, and the stop rod 16 disengages from the opening channel of the square compartment 15. Then, the second clamping plate 4 is rotated around the rotating axis 9 to open the clamping end 2, and the wire is placed in the first clamping opening 7 of the first clamping plate 3. Subsequently, the second clamping plate 4 is rotated in the opposite direction to bring it closer to the first clamping plate 3. The second clamping opening 8 of the second clamping plate 4 is in contact with the surface of the wire, and at the same time, the locking protrusion 13 is gradually inserted into the square compartment 15. When the first clamping plate 3 and the second clamping plate 4 are fully in contact, the pull ring 23 is released. Under the action of the elastic restoring force, the spring 20 pushes the stop rod 16 upwards to reset. The stop rod 16 abuts against the bottom of the locking protrusion 13, realizing the fixed connection between the first clamping plate 3 and the second clamping plate 4. The wire is firmly clamped in the connection port. Finally, the clamp is fixedly connected to the spacer bar 24 through the connection end 1 to complete the entire installation process.

[0035] When disassembly is required, the specific procedure is as follows: First, pull the pull ring 23 to move the stop bar 16 horizontally and release the limit on the locking protrusion 13. Then, open the second clamp 4 around the rotating shaft 9 to move it away from the first clamp 3. Finally, remove the spacer 24 from the wire to complete the disassembly of the spacer 24.

[0036] Example 2: A spacer bar clamp for disassembling a drone includes a connecting end 1 connected to a spacer bar 24 and a clamping end 2 connected to a wire. The clamping end 2 includes a first clamping piece 3, a second clamping piece 4, and a connector. The first clamping piece 3 and the second clamping piece 4 are respectively provided with a first clamping opening 7 and a second clamping opening 8, which form an annular connecting opening adapted to the wire when they are fitted together. The first clamping piece 3 is provided with a rotating shaft 9 away from the connecting end 1. The second clamping piece 4 cooperates with the first rotating hole 10 of the first clamping piece 3 through the second rotating hole 12 of the extension block 11, and rotates and opens and closes around the rotating shaft 9. The connector includes a snap-fit ​​protrusion 13 disposed on the second clamping piece 4 and a snap-fit ​​buckle 14 disposed on the first clamping piece 3. A stop bar 16 is horizontally disposed inside the snap-fit ​​buckle 14. The stop bar 16 moves horizontally in the axial direction connecting the connecting end 1 and the clamping end 2. Pull rods 21 are connected to both ends of the stop bar 16. The pull rods 21 extend toward the connecting end 1 and are connected to each other to form a pull ring 23 for pulling the drone. A sliding buckle 6 is disposed in the middle of the main body of the pull rod 21. A limiting hole 5 coaxial with the pull rod 21 is disposed on the sliding buckle 6. The pull rod 21 passes through the limiting hole 5 of the sliding buckle 6 and is bent and inclined near the connecting end 1.

[0037] The process for disassembling the drone using the aforementioned clamps includes: The first step involves the drone carrying a hook to attach to the connecting ring 23. The operator sets the drone's parameters at the ground control center, inputting the coordinates of the spacer bar 24 to be removed. The drone, carrying the matching hook, takes off and flies along a preset route to the area above the target spacer bar clamp. The drone's onboard high-definition camera transmits images in real time. The operator observes the images and adjusts the drone's attitude and altitude to align the hook with the spacer bar clamp's connecting ring 23, ensuring the hook is accurately attached to the ring 23. During this process, the drone must be kept stable and hovered to prevent the hook from shifting due to airflow or other factors, while ensuring a secure connection between the hook and the connecting ring 23 to prevent it from falling off during disassembly.

[0038] The second step involves pulling the pull ring 23 to confirm that the hook is securely attached. The operator then slowly moves the drone upwards a short distance, typically 5-10 centimeters, to allow the lever 16 to be pulled to unlock. As the drone moves upwards, the hook applies an upward pull through the pull ring 23. The inclined pull ring 23 changes the direction of the force and transmits the pull to the two levers 21, causing the levers 21 to move horizontally along the limiting hole 5 of the sliding buckle 6. This, in turn, causes the lever 16 to slide horizontally along the axial direction of the limiting pin 17, further compressing the spring 20. As the lever 16 moves horizontally, it gradually separates from the right-angled surface at the bottom of the locking protrusion 13. When the lever 16 moves to a position where it no longer limits the locking protrusion 13, the connector is unlocked, and the upward movement of the drone is stopped.

[0039] Third step, rotate to open the second clamp 4: After the connector is unlocked, the snap-fit ​​protrusion 13 loses the limiting constraint of the stop bar 16. Under the action of the elastic force of the wire and the weight of the second clamp 4 itself, the second clamp 4 rotates and opens away from the first clamp 3 with the rotation axis 9 as the fulcrum. The clamping end 2 changes from a closed state to an open state. At this time, the spacer clamp loses its double clamping effect on the wire. However, since the first clamping opening 7 of the first clamp 3 is still in contact with the wire, the spacer 24 can still stay on the wire briefly by relying on the first clamp 3.

[0040] The fourth step is to separate the wire from the spacer 24. After the operator confirms that the second clamp 4 is fully open through the drone's camera, the operator controls the drone to move slowly, gradually detaching the spacer 24 from the wire. Once the spacer 24 is completely detached from the wire, the operator controls the drone to fly along the preset return route and transport the spacer 24 back to the designated recovery area on the ground, thus completing the entire drone disassembly process for the spacer 24.
