Description

Technical Field

[0001] This utility model relates to the field of drone line deployment technology, and in particular to a drone line deployment construction device. Background Technology

[0002] In the construction of infrastructure such as power lines and communication optical cables, traditional methods of cable laying mainly rely on manual traction, ground machinery, or manned helicopter towing. These methods generally suffer from low efficiency, high cost, and significant limitations due to terrain, such as crossing complex environments like rivers, valleys, and forests, as well as significant impacts on personnel safety and vegetation ecology. With the maturity of drone technology, using drones for cable laying has become an efficient and flexible modern construction method. The basic principle is that the drone flies with a lightweight guide rope carried by a traction rope to complete the initial erection of the crossing section, and then completes the laying of heavy cables through step-by-step traction.

[0003] Most existing drone-based cable laying equipment uses only freely rotating spools. During the laying process, the cable tension depends entirely on the balance between flight speed and ground traction, which makes it prone to tension fluctuations. Excessive tension can cause the fiber optic cable or guide rope to break, while insufficient tension can cause the cable to sag and become entangled in the drone's propeller, leading to flight accidents. Furthermore, most cable laying equipment is still installed on the bottom of the drone using bolts. This requires multiple tightening or disassembly using tools before and after each mission. In scenarios involving multiple consecutive operations or emergency repairs, frequent loading and unloading severely impacts overall construction efficiency.

[0004] Therefore, a drone-based line deployment and construction device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a drone line deployment and construction device to solve the above-mentioned problems. It improves upon the fact that most existing drone line deployment and construction devices only use freely rotating spools, and the cable tension during the deployment process depends entirely on the balance between flight speed and ground traction, which is prone to tension fluctuations. Excessive tension can cause the optical cable or guide rope to break, while insufficient tension can cause the cable to sag and become entangled in the drone propeller, leading to flight accidents. Furthermore, most current deployment devices are still installed on the bottom of the drone by bolt fastening, requiring multiple tightening or disassembly using tools before and after each mission. In scenarios of multiple continuous operations or emergency repairs, frequent loading and unloading seriously affects the overall construction efficiency.

[0006] This utility model achieves the above objectives through the following technical solution: a drone-based line deployment and construction device, comprising:

[0007] Organism;

[0008] U-shaped mounting plate, wherein the U-shaped mounting plate is disposed at the lower end of the machine body;

[0009] The first rotating rod is rotatably connected to the inner walls of both sides of the U-shaped mounting plate, and one end of the first rotating rod extends out of one side of the U-shaped mounting plate.

[0010] A placement wheel is fixedly connected to the circumferential surface of the first rotating rod;

[0011] Two second rotating rods are respectively rotatably connected to the inner walls of the two sides of the U-shaped mounting plate, and the two second rotating rods are staggered vertically and horizontally.

[0012] Two guide pulleys are fixedly connected to the circumferential surfaces of the two second rotating rods, respectively.

[0013] A tension adjustment mechanism is provided on one side of the U-shaped mounting plate to apply constant tension to the cable during the cable laying process;

[0014] The quick-release mechanism is provided in multiple sets, with each set located at the lower end of the machine body to enable quick replacement of the U-shaped mounting plate.

[0015] Preferably, the tension adjustment mechanism includes a brake disc, a mounting shell, an adjusting screw hole, an adjusting screw, a compression spring, and an arc-shaped friction block. The brake disc is fixedly connected to the circumferential surface of the first rotating rod. The mounting shell is fixedly connected to one side of the U-shaped mounting plate. The adjusting screw hole is opened at one side of the mounting shell. The adjusting screw is threaded into the adjusting screw hole. One end of the compression spring is fixedly connected to one end of the adjusting screw. The arc-shaped friction block is fixedly connected to the other end of the compression spring. The arc-shaped friction block is slidably connected inside the mounting shell and fits against the circumferential surface of the brake disc.

[0016] Preferably, each set of the quick-release mechanism includes an arrow-shaped insert, a slot, a slide, a first spring, a beveled block, a pull rod, and a pop-out component. The arrow-shaped insert is fixedly connected to the upper end of the U-shaped mounting plate. The slot is located at the lower end of the body. The slide is located on one side of the inner wall of the slot. One end of the first spring is fixedly connected to one side of the inner wall of the slide. The beveled block is fixedly connected to the other end of the first spring and slidably connected within the slide. The pull rod is fixedly connected to one side of the beveled block. The pop-out component is located within the slot to quickly eject the U-shaped mounting plate.

[0017] Preferably, each of the ejector components includes a second spring and a stop plate, one end of the second spring is fixedly connected to the upper end of the slot, the stop plate is fixedly connected to the other end of the second spring, the stop plate is slidably connected in the slot, and the stop plate is attached to the upper end of the arrow-shaped insert.

[0018] Preferably, one side of the arrow-shaped insert is a slope, and one side of the sloped block is also a slope, with the sloped surfaces of the arrow-shaped insert and the sloped surfaces of the sloped block complementing each other.

[0019] Preferably, a connecting handle is fixedly connected to one side end of each pair of pull rods, and a limiting block is fixedly connected to the circumferential surface of the first rotating rod, the limiting block being attached to the inner wall of one side of the U-shaped mounting plate.

[0020] Preferably, guide frames are fixedly connected to the inner walls of both sides of the mounting housing at their close ends, and abutment plates are slidably connected inside the guide frames.

[0021] The beneficial effects of this utility model are:

[0022] 1. This device, through a tension adjustment mechanism consisting of a brake disc, adjusting screw, clamping spring, and arc-shaped friction block, can provide stable and preset frictional damping for the rotation of the first rotating rod and the placement wheel. This effectively overcomes the shortcomings of existing technologies where tension is passively balanced by flight speed and fluctuates greatly. During the cable laying process, this mechanism can actively suppress sudden tension changes caused by changes in flight speed, preventing cable breakage due to excessive tension or cable sagging and propeller entanglement due to insufficient tension. This fundamentally reduces the risk of flight accidents and ensures construction safety and cable laying quality.

[0023] 2. This device utilizes a quick-release mechanism comprised of arrow-shaped inserts, slots, inclined locking blocks, a first spring, and a pop-out assembly to achieve rapid locking and one-button release between the U-shaped mounting plate and its integrated functional modules and the main body. This completely changes the traditional bolt-fastening method, which is cumbersome to install and remove, requires tools, and is time-consuming. In continuous operations or emergency repair scenarios requiring frequent reel replacements, operators can replace the device by hand within seconds, significantly shortening the work interval and improving the utilization rate of the UAV platform and overall construction efficiency.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figures 1-5 The present invention provides the following technical solution:

[0033] A drone-based line deployment and construction device includes:

[0034] Body 1;

[0035] U-shaped mounting plate 2, which is located at the lower end of the body 1;

[0036] The first rotating rod 3 is rotatably connected to the inner walls of both sides of the U-shaped mounting plate 2, and one end of the first rotating rod 3 extends out of one side of the U-shaped mounting plate 2.

[0037] Place the wheel 4, which is fixedly connected to the circumferential surface of the first rotating rod 3;

[0038] Two second rotating rods 5 are respectively rotatably connected to the inner walls of the two sides of the U-shaped mounting plate 2, and the two second rotating rods 5 are staggered vertically and horizontally.

[0039] Two guide pulleys 6 are fixedly connected to the circumferential surfaces of the two second rotating rods 5 respectively;

[0040] Tension adjustment mechanism, which is set on one side of the U-shaped mounting plate 2 to apply constant tension to the cable during the cable laying process;

[0041] The quick-release mechanism has multiple sets, each set of which is located at the lower end of the body 1 to enable the quick replacement of the U-shaped mounting plate 2.

[0042] The tension adjustment mechanism includes a brake disc 7, a mounting shell 8, an adjusting screw hole 9, an adjusting screw 10, a compression spring 11, and an arc-shaped friction block 12. The brake disc 7 is fixedly connected to the circumferential surface of the first rotating rod 3. The mounting shell 8 is fixedly connected to one side of the U-shaped mounting plate 2. The adjusting screw hole 9 is opened at one side of the mounting shell 8. The adjusting screw 10 is threaded into the adjusting screw hole 9. One end of the compression spring 11 is fixedly connected to one end of the adjusting screw 10. The arc-shaped friction block 12 is fixedly connected to the other end of the compression spring 11. The arc-shaped friction block 12 is slidably connected inside the mounting shell 8 and fits against the circumferential surface of the brake disc 7.

[0043] In a specific embodiment of this utility model, when a cable laying operation is required, the placement wheel 4 with the cable wound around it is first installed on the first rotating rod 3. After one end of the cable is fixed, the cable is sequentially passed around two guide pulleys 6 arranged in a staggered manner. Then, by rotating the adjusting screw 10 set on the mounting shell 8, the adjusting screw 10 moves axially within the adjusting screw hole 9 opened in the mounting shell 8, thereby compressing or releasing the compression spring 11 sleeved at its end. The compression spring 11 transmits the elastic force to the arc-shaped friction block 12 fixedly connected to it, pushing the arc-shaped friction block 12 to slide along the guide structure within the mounting shell 8, so that its arc surface presses against the circumferential surface of the brake disc 7 fixed on the first rotating rod 3. When the drone pulls the cable, the cable is pulled out from the placement wheel 4, causing the placement wheel 4 to move along the first rotating rod 3. As the first rotating rod 3 rotates, a preset frictional resistance is generated between the brake disc 7 fixed on the first rotating rod 3 and the arc-shaped friction block 12 subjected to the pressure of the compression spring 11. When the cable laying speed changes, this frictional resistance inhibits or releases the rotation of the first rotating rod 3, thereby applying a basically constant tension to the cable that can be preset by adjusting the screw 10, preventing the cable from loosening during the laying process. Personnel can apply low-strength anaerobic thread-locking adhesive to the connection between the adjusting screw 10 and the adjusting screw hole 9, which can effectively prevent the adjusting screw 10 from retracting on its own due to high-frequency vibration during the flight of the UAV. While ensuring the stability of the tension setting value, it can still be easily adjusted by hand without affecting subsequent tension parameter modifications. The quick disassembly and assembly mechanism allows personnel to quickly disassemble and assemble the U-shaped mounting plate 2 and all the integrated functional modules on it without using any tools.

[0044] Please refer to the details. Figures 1-5Each quick-release mechanism includes an arrow-shaped insert 13, a slot 14, a slide 15, a first spring 16, a sloping block 17, a pull rod 18, and a pop-out component. The arrow-shaped insert 13 is fixedly connected to the upper end of the U-shaped mounting plate 2. The slot 14 is opened at the lower end of the body 1. The slide 15 is opened on one side of the inner wall of the slot 14. One end of the first spring 16 is fixedly connected to one side of the inner wall of the slide 15. The sloping block 17 is fixedly connected to the other end of the first spring 16 and is slidably connected in the slide 15. The pull rod 18 is fixedly connected to one side of the sloping block 17. The pop-out component is set in the slot 14 to quickly push out the U-shaped mounting plate 2.

[0045] Each pop-out assembly includes a second spring 19 and a stop plate 20. One end of the second spring 19 is fixedly connected to the upper end of the slot 14, and the stop plate 20 is fixedly connected to the other end of the second spring 19. The stop plate 20 is slidably connected inside the slot 14 and fits against the upper end of the arrow-shaped insert 13.

[0046] In this embodiment: When it is necessary to install the U-shaped mounting plate 2 with a tension adjustment mechanism, the operator holds the U-shaped mounting plate 2 and inserts it with the arrow-shaped insert 13 at its upper end aligned with the slot 14 at the lower end of the machine body 1. During the insertion process, the arrow-shaped insert 13 first contacts and compresses the second spring 19 located at the upper end of the slot 14. The second spring 19 transmits force to the abutment plate 20 fixed thereto, causing the abutment plate 20 to press tightly against the upper end of the arrow-shaped insert 13 and slide accordingly. At the same time, the inclined surface of the arrow-shaped insert 13 pushes the inclined plate block 17 in the slide groove 15. The inclined plate block 17 is squeezed into the slide groove 15, compressing the first spring 16 connected thereto. When the arrow-shaped insert 13 is fully inserted into the predetermined position, the compressed first spring 16 releases its elastic force, pushing... The inclined plate 17 slides outward, locking itself into the lower end of the arrow-shaped insert 13, while the second spring 19 is in a compressed, energy-storing state. When the U-shaped mounting plate 2 needs to be replaced or disassembled, the operator pulls the lever 18, which is fixedly connected to the inclined plate 17, outward. The lever 18 drives the inclined plate 17 to overcome the elastic force of the first spring 16 and slide into the groove 15, so that it completely disengages from the lower end of the arrow-shaped insert 13. At the same time, the second spring 19, which is in a compressed state, pushes the abutment plate 20, which transmits the force to the upper end of the arrow-shaped insert 13, automatically and smoothly ejecting the arrow-shaped insert 13 from the slot 14. Thus, the U-shaped mounting plate 2 and all the integrated functional modules on it can be quickly disassembled without the use of tools.

[0047] Please refer to the details. Figures 1-5 One side of the arrow-shaped insert 13 is a slope, and one side of the sloped block 17 is also a slope. The slopes of the arrow-shaped insert 13 and the slopes of the sloped block 17 are matched.

[0048] In this embodiment: when the U-shaped mounting plate 2 is installed onto the body 1, the arrow-shaped insert 13 is inserted along the slot 14. The inclined surface on the arrow-shaped insert 13 will first contact the inclined surface on the inclined plate 17. After the two inclined surfaces contact each other, the continued insertion of the arrow-shaped insert 13 will, through the interaction of the inclined surfaces, convert the horizontal thrust into a force that causes the inclined plate 17 to move inward along the slide groove 15, thereby compressing the first spring 16. When the arrow-shaped insert 13 is fully in place and the end of its inclined surface passes the highest point of the inclined plate 17, the first spring 16 pushes the inclined plate 17 back to its original position, and its flat part engages with the flat structure at the lower end of the arrow-shaped insert 13, thus realizing smooth guidance and automatic locking during the installation process.

[0049] Please refer to the details. Figures 1-5 A connecting handle 21 is fixedly connected to one side end of each pair of pull rods 18. A limiting block 23 is fixedly connected to the circumferential surface of the first rotating rod 3. The limiting block 23 is attached to the inner wall of one side of the U-shaped mounting plate 2.

[0050] In this embodiment: To facilitate the simultaneous operation of multiple quick-release mechanisms, the ends of the pull rods 18 located on the two quick-release mechanisms are fixedly connected together by a connecting handle 21. When the U-shaped mounting plate 2 needs to be disassembled, the operator only needs to pull the two connecting handles 21 with both hands to simultaneously drive all the connected pull rods 18 and the inclined plate locking block 17 to unlock all locking points, which greatly improves the operating efficiency. At the same time, when the first rotating rod 3 rotates, the limiting block 23 rotates accordingly and is restricted within the axial space of one side inner wall of the U-shaped mounting plate 2, thereby ensuring the axial positioning stability of the first rotating rod 3 and the placement wheel 4 installed on it during the rotation process.

[0051] Please refer to the details. Figures 1-5 Guide frames 22 are fixedly connected to the inner walls of the two sides of the housing 8 near each other, and abutment plates 20 are slidably connected inside the guide frames 22.

[0052] In this embodiment: when the adjusting screw 10 is rotated, it generates axial displacement in the adjusting screw hole 9, and its body is simultaneously restricted to slide smoothly along a predetermined straight path in the guide frame 22. This ensures that the force transmission direction of the adjusting screw 10 is accurate and without deviation during the process of pushing the compression spring 11 and the arc-shaped friction block 12, thereby making the friction pressure applied to the brake disc 7 stable, adjustable and linearly controllable.

[0053] Workflow: First, the cable-wound placement wheel 4 is installed onto the first rotating rod 3, and the first rotating rod 3 is assembled into the U-shaped mounting plate 2. A axial movement is prevented by the limiting block 23. By rotating the adjusting screw 10, it moves axially within the adjusting screw hole 9 and compresses the clamping spring 11. The clamping spring 11 pushes the arc-shaped friction block 12 to press against the brake disc 7, thus preseting the initial tension. Before operation, the U-shaped mounting plate 2, integrating the above components, is inserted into the slot 14 of the machine body 1 through the arrow-shaped insert 13. During insertion, the arrow... The inclined surface of the arrow-shaped insert 13 pushes the inclined surface locking block 17 to compress the first spring 16. After it is in place, the inclined surface locking block 17 engages and locks. At the same time, the arrow-shaped insert 13 compresses the second spring 19 and the abutment plate 20 to store energy. When the drone pulls the cable, the cable drives the placement wheel 4 and the first rotating rod 3 to rotate. The brake disc 7 and the arc-shaped friction block 12 generate constant frictional resistance to achieve constant tension cable release. When replacing, pull the connecting handle 21 to drive the pull rod 18 to disengage the inclined surface locking block 17. The second spring 19 pops out the arrow-shaped insert 13 through the abutment plate 20 to complete the quick disassembly.
