[0015] The beneficial effects of the phase-to-phase spacer bar UAV installation system provided in this application are as follows: Compared with the prior art, this application uses a UAV as the installation carrier, eliminating the defects of traditional conductor flying carts, insulator strings, or suspended baskets that sway with the conductor. The UAV can hover stably through its own power system, and is significantly less affected by wind than manual platforms, greatly reducing the interference of the working environment on installation stability and solving the problem of difficulty in maintaining balance manually. Through the cooperation of the clamps on the installation frame and the drive mechanism, manual clamping is unnecessary. The drive mechanism drives the clamps to slide in opposite directions to clamp the cable, avoiding the dual interference of overcoming one's own balance and conductor vibration during swaying, reducing installation difficulty, and improving clamping accuracy and reliability. The battery on the hoisting cable powers the drive mechanism, eliminating the need for an external power source on site, adapting to high-altitude outdoor working environments, ensuring stable power of the drive mechanism during installation, and preventing installation failure due to power outages. The lifting ring and clamping block are linked by a transmission mechanism. When the clamping block slides, the opening and closing of the lifting ring is automatically controlled. Before the clamping block clamps and fixes the cable, the lifting ring closes to ensure that the UAV is stably lifted and installed on the mounting frame through the lifting buckle. When the clamping block has finished clamping and fixing the cable, the lifting ring opens and the lifting buckle can automatically disengage, realizing the rapid separation of the UAV from the mounting frame without manual intervention in the separation process, which further improves the installation efficiency. Moreover, the entire process does not require manual contact with high-voltage wires, which improves the safety of the operation. Attached Figure Description

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0024] The phase-spacer bar UAV installation system provided in this application will now be described.

[0025] Please refer to the following: Figures 1 to 15 The phase-spacer bar UAV installation system includes a UAV 1 with two mounting rings at the bottom, a lifting cable 2 connected to each mounting ring, two mounting frames 4 below the UAV 1, two ends of the spacer bar 5 fixed to the two mounting frames 4 respectively, two clamping blocks slidably mounted on the mounting frames 4, and a drive mechanism detachably mounted on the mounting frames 4 connected to the two clamping blocks. The drive mechanism is used to drive the clamping blocks to slide towards each other so that the two clamping blocks clamp the two sides of the cable. A battery 3 is fixed on the lifting cable 2 and is used to power the drive mechanism. The top of the mounting frame 4 is provided with an openable lifting ring, and a transmission mechanism is provided between the lifting ring and the clamping blocks so that the lifting ring can be closed or opened due to the sliding of the clamping blocks. The bottom end of the lifting cable 2 is provided with a hook, which is sleeved on the lifting ring and can be detached from the lifting ring when the lifting ring is opened.

[0026] The beneficial effects of the phase-to-phase spacer unmanned aerial vehicle (UAV) installation system provided in this embodiment are as follows: Compared with the prior art, the phase-to-phase spacer UAV installation system provided in this embodiment uses UAV 1 as the installation carrier, which gets rid of the defects of traditional conductor flying cars, insulator strings or hanging baskets swaying with the conductor. UAV 1 can hover stably through its own power system, and is significantly less affected by wind than manual platforms, which greatly reduces the interference of the working environment on the installation stability and solves the problem of difficulty in balancing by humans.

[0027] The clamping blocks on mounting bracket 4 work in conjunction with the drive mechanism, eliminating the need for manual clamping. The drive mechanism drives the clamping blocks to slide in opposite directions to clamp the cable, avoiding the dual interference of manual effort to overcome both self-balance and cable vibration during shaking. This reduces installation difficulty and improves clamping accuracy and reliability. The battery 3 on the lifting cable 2 powers the drive mechanism, eliminating the need for an external power source. This adapts to high-altitude outdoor working environments, ensuring stable power for the drive mechanism during installation and preventing installation failure due to power outages.

[0028] The lifting ring and clamping block are linked by a transmission mechanism. When the clamping block slides, the opening and closing of the lifting ring is automatically controlled. Before the clamping block clamps and fixes the cable, the lifting ring closes to ensure that the UAV 1 is stably lifted and mounted on the mounting frame 4 by the lifting buckle. When the clamping block has finished clamping and fixing the cable, the lifting ring opens and the lifting buckle can automatically disengage, realizing the rapid separation of the UAV 1 from the mounting frame 4 without manual intervention in the separation process, which further improves the installation efficiency. Moreover, the entire process does not require manual contact with high-voltage wires, which improves the safety of the operation.

[0029] Combination Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the clamping block includes a first clamping block 401 and a second clamping block 402. The top of the first clamping block 401 is provided with two first racks 403 spaced apart, and the top of the first racks 403 is provided with a T-shaped first limiting strip 404. The top of the second clamping block 402 is provided with two second racks 405 spaced apart, and the top of the second racks 405 is provided with a T-shaped second limiting strip 406. The interval between the two first racks 403 is greater than the interval between the two second racks 405.

[0030] The mounting bracket 4 has two linkage slots 407, which are arranged at intervals. A first linkage gear 408 is rotatably mounted on the bottom of each linkage slot 407. A first limiting slot 412 and a second limiting slot 413 are also provided on the bottom of each linkage slot 407, located on opposite sides of the first linkage gear 408. When the first clamping block 401 is installed, two first racks 403 are positioned within the two linkage slots 407. The first racks 403 mesh with the first linkage gear 408 within the same linkage slot 407, and a first limiting strip 404 slides within the first limiting slot 412. When the second clamping block 402 is installed in place, the two second racks 405 are respectively disposed in the two linkage grooves 407. The second racks 405 mesh with the first linkage gear 408 in the same linkage groove 407, and the second limiting strip 406 is slidably disposed in the second limiting groove 413. In the same linkage groove 407, the first rack 403 and the second rack 405 are respectively disposed on both sides of the first linkage gear 408.

[0031] The first rack 403 of the first clamping block 401 and the second rack 405 of the second clamping block 402 respectively mesh with the first linkage gear 408 in the linkage groove 407 of the mounting frame 4, ensuring the synchronicity of the two clamping blocks when they slide towards each other under the action of the drive mechanism. Compared with clamping blocks without a linkage structure, this avoids clamping block offset caused by uneven driving force on both sides, ensures uniform distribution of clamping force on the cable, prevents local deformation or damage to the cable due to uneven force, and ensures accurate installation position of the spacer 5.

[0032] The T-shaped first limiting strip 404 engages with the first limiting groove 412, and the second limiting strip 406 engages with the second limiting groove 413, restricting the displacement of the clamping block from the dimension perpendicular to the sliding direction, preventing the clamping block from shifting up and down or left and right during sliding. This dual limiting design solves the problem of misalignment of the clamping block caused by shaking during manual installation, ensuring that the clamping block always slides along the preset trajectory, thus improving the reliability of the clamping action. Furthermore, the design that the spacing of the first rack 403 is greater than the spacing of the second rack 405 ensures that the installation of the first clamping block 401 and the second clamping block 402 in the linkage groove 407 does not interfere with each other, and both can effectively mesh with the same set of first linkage gears 408.

[0033] like Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, locking half holes 409 are provided on the opposing surfaces of the first clamping block 401 and the second clamping block 402. The locking half holes 409 are located near the top of the first clamping block 401 or the second clamping block 402. When the first clamping block 401 and the second clamping block 402 abut against each other, the two locking half holes 409 form a locking hole 410, and the inner wall of the locking hole 410 abuts against the outer peripheral surface of the cable.

[0034] After the locking half-holes 409 of the first clamping block 401 and the second clamping block 402 are closed, a locking hole 410 that is adapted to the cable is formed. The arc-shaped structure that fits the shape of the cable increases the contact area. Compared with flat clamping, it can reduce the local pressure on the cable and avoid damage to the cable insulation layer. At the same time, it increases the clamping friction and prevents the spacer 5 from slipping due to conductor vibration after installation.

[0035] A mounting half-groove is provided on the opposing surfaces of the first clamping block 401 and the second clamping block 402. A rubber block is fixedly installed in the mounting half-groove. A locking half-hole 409 is opened near the top of the rubber block, and the diameter of the locking half-hole 409 can be slightly smaller than the diameter of the cable. The setting of the rubber block allows the locking half-hole 409 to deform. At the same time, since the diameter of the locking half-hole 409 is slightly smaller than the diameter of the cable, the inner wall of the locking hole 410 can better press against the cable, which is more conducive to the fixation of the cable. At the same time, the locking half-hole 409 is located near the top of the rubber block, so that the locking hole 410 is located near the top of the second clamping block 402. In the actual installation, the mounting bracket 4 is first overlapped on the two cables, and the cables should be located between the first clamping block 401 and the second clamping block 402 on the same side. As the first clamping block 401 and the second clamping block 402 approach each other, the cable can be squeezed into the locking hole 410.

[0036] A locking rod 411 is provided on the side of the first clamping block 401 facing the second clamping block 402, and a third limiting groove 414 is provided on the side wall of the locking rod 411; a locking slot 415 is provided on the side of the second clamping block 402 facing the first clamping block 401, and a fourth limiting groove 416 is provided on one side of the locking slot 415. A limiting rod 417 is slidably provided in the fourth limiting groove 416, and a first spring 418 is provided between the limiting rod 417 and the bottom of the fourth limiting groove 416. The first spring 418 is configured with a preload force to make the limiting rod 417 extend out of the fourth limiting groove 416. The limiting rod 417 can retract under the compression of the locking rod 411. When the third limiting groove 414 and the fourth limiting groove 416 are aligned, the limiting rod 417 is inserted into the third limiting groove 414.

[0037] The locking rod 411 and the locking slot 415 cooperate, and the limiting rod 417 and the first spring 418 elastically lock together to form a physical insertion and fixation. After the locking rod 411 is inserted into the locking slot 415, the limiting rod 417 is locked into the third limiting groove 414 under the action of the first spring 418, preventing the rod from falling off. This effectively avoids the clamping block from loosening due to long-term vibration of the wire or electromagnetic force, and solves the problem of the mounting bracket 4 not clamping the cable securely.

[0038] In this embodiment, when the first spring 418 is in its natural state, the limiting rod 417 is partially disposed in the locking slot 415, and the limiting rod 417 can be completely retracted into the fourth limiting groove 416 due to sliding. In addition, the bottom end of the limiting rod 417 is arranged at an angle from high to low along the insertion direction of the locking hole, so that when the locking rod 411 is inserted, the limiting rod 417 can be automatically pushed to retract by the inclined surface. After being inserted into place, the limiting rod 417 automatically resets and locks, realizing the automated operation of "insertion and locking", reducing the installation steps, adapting to the remote control needs of the UAV1, and improving the installation efficiency.

[0039] In this embodiment, the mounting frame 4 includes a first mounting plate 419, a second mounting plate 420, and a drive mounting plate 421. The first mounting plate 419 is arranged horizontally, and the second mounting plate 420 is arranged vertically and connected to the first mounting plate 419. The drive mounting plate 421 is vertically mounted on the second mounting plate 420. A linkage groove 407 is formed at the bottom of the first mounting plate 419. A first drive cylinder 422 is rotatably mounted on the second mounting plate 420. A first bevel gear ring 423 is provided on the outer wall of the first drive cylinder 422. A second drive cylinder 425 is rotatably mounted on the drive mounting plate 421. A second bevel gear ring 424 is provided on the outer wall of the second drive cylinder 425. The first bevel gear ring 423 meshes with the second bevel gear ring 424. A first worm gear 426 is internally threaded to the first drive cylinder 422. The axial direction of the first worm gear 426 is parallel to the sliding direction of the two clamping blocks. One end of the first worm gear 426 is rotatably mounted on the side wall of the second clamping block 402.

[0040] The L-shaped connection design of the first mounting plate 419, the second mounting plate 420 and the drive mounting plate 421 forms a multi-dimensional force support. Compared with a single flat plate structure, it can withstand greater clamping reaction force and the weight of the spacer bar 5, avoid deformation of the mounting frame 4 during hoisting or clamping, ensure the structural strength for long-term use, and adapt to complex high-altitude stress environments.

[0041] The engagement of the first bevel gear ring 423 and the second bevel gear ring 424 enables vertical steering of the power, making the installation position of the first motor of the drive mechanism more flexible and adaptable to the space constraints when hoisting the UAV 1. This avoids interference between the transmission components and the cables and spacers 5. Simultaneously, the bevel gear transmission offers high meshing precision and low power transmission loss, ensuring that the torque of the drive mechanism is efficiently converted into the clamping force of the clamping blocks. The threaded connection between the first drive cylinder 422 and the first worm gear 426 stably converts rotational motion into linear sliding of the clamping blocks. The clamping force can be adjusted by the motor speed and rotation time to avoid over- or under-clamping.

[0042] The inner cavity of the second drive cylinder 425 has a polygonal cross-section. The drive mounting plate 421 is made of magnetic material. The drive mechanism includes a first motor and electromagnets located on both sides of the first motor. The first motor is fixed to the hoisting cable 2. The power output end of the first motor is provided with a drive rod 445. The shape of the drive rod 445 is adapted to the inner cavity of the second drive cylinder 425. The drive rod 445 is inserted into the inner cavity of the second drive cylinder 425. The electromagnets can be wirelessly controlled and are magnetically fixed to the drive mounting plate 421. Specifically, the magnetic material here can be any one of iron, cobalt, or nickel. In addition, the electromagnets are controlled to open and close via a remote control. At the same time, a switch that can be opened or closed via a remote control can also be set between the battery 3 and the electromagnet. In this case, a non-remote-controlled electromagnet can be used. As long as the switch is closed by remote control, the electromagnet can be detached from the drive mounting plate 421.

[0043] The polygonal fit between the inner cavity of the second drive cylinder 425 and the drive rod 445 ensures slip-free power transmission and improves the stability of the power coupling between the drive mechanism and the mounting bracket 4. The drive mounting plate 421 uses magnetic material, and the first motor is fixed by electromagnet attraction. No manual tightening of bolts is required during installation, and separation can be achieved simply by remotely turning off the electromagnet. This significantly shortens the assembly and separation time between the drive mechanism and the mounting bracket 4, and is compatible with remote control of the UAV 1, avoiding manual high-altitude operation and improving work efficiency and safety.

[0044] In addition, a mounting groove 427 is provided on the side wall of the second clamping block 402, and a fixing plate 428 is provided on the opening of the mounting groove 427. The fixing plate 428 is fixed to the second clamping block 402 by bolts. The first worm gear 426 includes a first large-diameter rod 429, a second large-diameter rod 430, and a small-diameter rod 431. The small-diameter rod 431 is connected between the first large-diameter rod 429 and the second large-diameter rod 430. The first large-diameter rod 429 and the second large-diameter rod 430 have the same diameter, and the diameter of the first large-diameter rod 429 is larger than the diameter of the small-diameter rod 431. The second large-diameter rod 430 is threadedly connected to the first drive cylinder 422. The first large-diameter rod 429 is located in the mounting groove 427, and the small-diameter rod 431 passes through the fixing plate 428.

[0045] The segmented design of the first major diameter rod 429, minor diameter rod 431 and second major diameter rod 430 of the first worm gear 426 allows the worm gear to be stably installed in the mounting slot 427, and to be limited by the minor diameter rod 431 passing through the fixed plate 428, ensuring transmission accuracy, while also adapting to the compact space layout within the mounting frame 4.

[0046] As a preferred technical solution, a plurality of first limiting teeth 432 are evenly arranged on the outer wall of the first large-diameter rod 429, and a coil spring 433 is provided between the first large-diameter rod 429 and the bottom of the mounting groove 427. Driven by the first motor, the first worm gear 426 rotates forward, and the coil spring 433 stores energy; when the first motor is disassembled, the coil spring 433 releases energy and drives the first worm gear 426 to reverse and reset. Figure 12 The arrow shown indicates the direction of the first worm gear 426's forward rotation.

[0047] A fifth limiting groove 434 is provided on one side of the mounting groove 427. A limiting plate 435 is slidably provided on the side wall of the fifth limiting groove 434. The limiting plate 435 can be inserted between two adjacent first limiting teeth 432 due to sliding, or can be completely retracted into the fifth limiting groove 434. The limiting plate 435 is inclined in the expected forward rotation direction of the first large diameter rod 429, and the limiting plate 435 is an elastic member, so that when the limiting plate 435 is partially provided between adjacent first limiting teeth 432, the first worm gear 426 can rotate forward and cannot rotate backward.

[0048] The coil spring 433 between the first large-diameter rod 429 and the bottom of the mounting groove 427 stores energy when the first motor drives the worm gear to rotate forward. When disassembly is required, there is no need to reinstall the drive mechanism. Simply slide the limit plate 435 to contact the limit plate 435's limit on the large-diameter rod, which releases the energy of the coil spring 433 to drive the worm gear to rotate in reverse, causing the clamping block to automatically reset, facilitating subsequent disassembly and replacement.

[0049] The structure of the elastic limiting plate 435 engaging with the first limiting tooth 432 allows the worm gear to rotate forward to drive the clamping block to clamp, but prevents it from rotating backward, thus preventing the clamping block from loosening after the first motor is disassembled, forming a one-way locking mechanism. This design avoids worm gear reversal caused by wire vibration, wind impact, or accidental contact, ensuring that the clamping block always remains clamped. It solves the hidden danger of loosening due to external force after traditional manual installation, and improves the long-term stability of the spacer bar 5.

[0050] like Figure 11 and Figure 12As shown, a first gear 436 is rotatably provided on one side of the fourth limiting groove 416, and a rack is provided for the limiting rod 417. The first gear 436 meshes with the limiting rod 417. A first unlocking groove 437 is provided on one side of the first gear 436, and a first unlocking rack 438 is slidably provided in the first unlocking groove 437, meshing with the first gear 436. A guide groove 439 is provided above the fifth limiting groove 434, and a guide rack 440 is slidably provided in the guide groove 439. The bottom end of the guide rack 440 is fixedly connected to the limiting plate 435, and a second spring 441 is provided between the top end of the guide rack 440 and the bottom of the guide groove 439. The second spring 441 is configured with a preload force to allow the limiting plate 435 to be inserted between the adjacent first limiting teeth 432, and the limiting plate 435 can retract under the action of external force. A second gear 442 is rotatably provided on one side of the first guide groove 439. The guide rack 440 meshes with the second gear 442. A second unlocking groove 443 is provided on one side of the second gear 442. A second unlocking rack 444 is slidably provided in the second unlocking groove 443. The second unlocking rack 444 meshes with the second gear 442.

[0051] The engagement of the first gear 436, the first unlocking rack 438, and the rack of the limiting rod 417, as well as the engagement of the second gear 442, the second unlocking rack 444, and the guide rack 440, enables the unlocking control of the limiting rod 417 and the limiting plate 435. When it is necessary to release the locking state of the limiting rod 417 on the clamping block or adjust the limiting state of the limiting plate 435 on the first worm gear 426, the first unlocking rack 438 and the second unlocking rack 444 can be operated to drive the first gear 436 and the second gear 442 to rotate, thereby retracting the limiting rod 417 and the limiting plate 435. At this time, the coil spring 433 can release energy to drive the first worm gear 426 to reverse. This design avoids the inconvenience and danger of manual unlocking at heights or in complex environments, improving the efficiency and safety of installation operations. Meanwhile, the second spring 441 ensures that under normal circumstances, the limiting plate 435 can automatically remain in the position of limiting the first worm gear 426, ensuring the stability and reliability of the installation system.

[0052] Combination Figure 13As shown, the first unlocking groove 437 is strip-shaped and is located between the two first gears 436. The second unlocking groove 443 is also strip-shaped, with one end of the second unlocking groove 443 communicating with the middle of the first unlocking groove 437 in a T-shape. The second unlocking rack 444 is slidably disposed at the end of the second unlocking groove 443 away from the first unlocking groove 437. The long axis of the first unlocking rack 438 is parallel to the depth direction of the first unlocking groove 437, and the long axis of the second unlocking rack 444 is parallel to the depth direction of the second unlocking groove 443. The top of the first unlocking rack 438 and the second unlocking rack 444 is provided with a T-shaped drive rod 445, and the top of the drive rod 445 is provided with a pressing rod 446, which extends beyond the second clamping block 402.

[0053] By designing the first unlocking slot 437 and the second unlocking slot 443 as a conductive T-shaped structure, and providing a T-shaped drive rod 445 and a pressing rod 446 extending outside the second clamping block 402, the operator can conveniently operate the first unlocking rack 438 and the second unlocking rack 444 from the outside. When unlocking is required, the operator only needs to press the pressing rod 446, and the drive rod 445 will drive the first unlocking rack 438 and the second unlocking rack 444 to slide simultaneously, thereby unlocking the limiting rod 417 and the limiting plate 435 respectively. This integrated operation design greatly simplifies the unlocking process and improves the convenience and accuracy of operation. Compared with the traditional method of operating multiple unlocking components separately, it reduces the number of operation steps and the possibility of errors, and is especially suitable for installation operations on UAVs 1 in high-altitude or complex environments, further improving the practicality and reliability of the spacer bar 5 installation system.

[0054] Furthermore, in this embodiment, the top end of the pressing lever 446 extends below the second clamping block 402. This prevents animals such as birds from accidentally pressing the pressing lever 446, and also avoids accidental pressing of the pressing lever 446 by ice storms, thus improving the safety of the mounting bracket 4.

[0055] Combination Figure 14 and Figure 15 As shown, the lifting ring includes a semi-ring cylinder 447 and a semi-ring body 448. The semi-ring cylinder 447 is mounted on the first mounting plate 419. The semi-ring body 448 is inserted into the semi-ring cylinder 447 and can slide along the long axis of the semi-ring cylinder 447 to form a complete ring, or to form a gap between the semi-ring body 448 and the semi-ring cylinder 447. When the semi-ring cylinder 447 and the semi-ring cylinder 447 form a complete ring, the lifting ring is closed. When the semi-ring body 448 is inserted into the semi-ring cylinder 447 and the semi-ring body 448 and the semi-ring cylinder 447 are joined together to form a fan-shaped ring with a missing top, the lifting ring is open.

[0056] The lifting ring employs a combination design of a semi-ring cylinder 447 and a semi-ring body 448. The lifting ring is opened and closed by inserting and removing the semi-ring body 448 within the semi-ring cylinder 447. During installation, the semi-ring body 448 is pulled out of the semi-ring cylinder 447, forming a complete ring with it. At this point, the lifting ring is closed and can be connected to the lifting cable 2 via the lifting buckle, ensuring the stability of the entire installation system during installation. After the mounting frame 4 is attached to the cable, the lifting cable 2 no longer provides support. As the clamps slide relative to each other, the semi-ring body 448 is also inserted into the semi-ring cylinder 447, forming the missing top fan-shaped ring with it. The lifting ring opens, the lifting buckle can easily disengage from the lifting ring, and the drone 1 can quickly leave the installation site. Compared to traditional complex lifting ring structures, this structural design is not only cheaper to manufacture but also simpler and more intuitive to operate, enabling it to work reliably in various complex environments. At the same time, its simple structure reduces the overall cost of the installation system and improves its practicality.

[0057] In this embodiment, a transmission groove 449 is provided on the first mounting plate 419, and a transmission shaft is rotatably provided in the transmission groove 449. A transmission wheel 451 and a first transmission gear 450 are fixedly provided on the transmission shaft. The diameter of the transmission wheel 451 is greater than the thickness of the first mounting plate 419, and the transmission wheel 451 is an elastic member. The diameter of the first transmission gear 450 is not greater than the thickness of the first mounting plate 419. A second transmission gear 452 and a third transmission gear 453 are rotatably provided above the first mounting plate 419. The third transmission gear 453 meshes with the second transmission gear 452, and the second transmission gear 452 meshes with the first transmission gear 450. The semi-ring 448 is a toothed ring, and the semi-ring 448 meshes with the third transmission gear 453.

[0058] The top of the first mounting plate 419 is provided with a protective box 456, which covers the semi-ring cylinder 447, the second transmission gear 452 and the third transmission gear 453, and the top of the semi-ring cylinder 447 is fixed to the top wall of the protective box 456.

[0059] A complete and precise transmission system is constructed through the transmission wheel 451 and the first transmission gear 450 on the transmission shaft, as well as the meshing second transmission gear 452 and the third transmission gear 453 and the semi-ring body 448 acting as a gear ring. When external power drives the transmission wheel 451 to rotate, the transmission shaft drives the first transmission gear 450 to rotate, which in turn drives the second transmission gear 452 and the third transmission gear 453 to rotate in sequence, ultimately driving the semi-ring body 448 to slide within the semi-ring cylinder 447, realizing the opening and closing of the lifting ring. This multi-stage gear transmission structure can effectively reduce energy loss during the transmission process, improve transmission efficiency, and ensure the smoothness and accuracy of the transmission, ensuring that the lifting ring can complete the opening and closing action as expected with precision, further guaranteeing the stability of the installation system during the installation process. Theoretically, the first transmission gear 450 and the semi-ring body 448 could also achieve transmission by directly meshing, but to avoid obstructing the installation space of the semi-ring cylinder 447, the second transmission gear 452 and the third transmission gear 453 are used for transmission.

[0060] The transmission wheel 451 is constructed with elasticity and has a diameter greater than the thickness of the first mounting plate 419, a design that offers unique advantages. The elasticity of the transmission wheel 451 provides cushioning when it contacts the first clamping block 401, reducing impact during transmission and extending the service life of the transmission components. The larger diameter design allows the transmission wheel 451 to more easily contact the first clamping block 401 and transmit power, reducing the difficulty of power transmission and improving transmission reliability. In this embodiment, the transmission wheel 451 is a rubber wheel.

[0061] The protective box 456 encloses the semi-ring cylinder 447, the second transmission gear 452, and the third transmission gear 453, effectively preventing external dust, rainwater, debris, and other contaminants from corroding and interfering with these critical transmission components. This avoids wear, corrosion, or jamming of the transmission components due to external environmental factors, ensuring the long-term stable operation of the transmission system and greatly reducing equipment maintenance costs and failure rates. In addition, the diameter of the first transmission gear 450 is no greater than the thickness of the first mounting plate 419. This design allows the transmission gear to better fit the structure of the first mounting plate 419, avoiding excessive gear protrusion and interference with other components. This ensures the compactness and rationality of the entire mounting frame 4 structure, creates favorable conditions for the coordinated work of various components, and further improves the overall performance of the phase-spacer bar UAV mounting system.

[0062] The bottom surface of the first mounting plate 419 is provided with multiple fixing grooves 455. The nuts of the fixing bolts 454 are set in the fixing grooves 455. The fixing grooves 455 are hexagonal and the nuts of the fixing bolts 454 are also hexagonal. On the one hand, the sliding of the clamping block can be avoided, and on the other hand, the fixing bolts 454 can be fixed in the circumferential direction.

[0063] The top of the fixing bolt 454 extends above the first mounting plate 419. Fixing holes are arranged at both ends of the spacer 5. The fixing bolt 454 is inserted into the fixing holes, and the nut of the fixing bolt 454 is pressed against the spacer 5, so that the spacer 5 is fixed relative to the mounting bracket 4.

[0064] In this embodiment, the battery 3 can be tied and fixed to the lifting cable 2, or it can be fixed to the lifting cable 2 in other ways. The battery 3 and the drive mechanism are connected by an armored cable. When the drive mechanism is detached from the mounting frame 4, the armored cable plays a role in lifting the drive mechanism.

[0065] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
