Abstract
Description
Technical Field
[0001] The utility model relates to the field of wire retracting and extending devices for wire drones, in particular to a wire retracting and extending device for wire drones. Background Art
[0002] With the rapid development of technology, conductor drones have found widespread application in numerous fields. During power line inspections, they can accurately inspect overhead transmission lines and promptly identify potential hazards. For the installation and maintenance of communication lines, they can efficiently complete the stringing of fiber optic and other conductors. Their flexible maneuverability and convenient operation significantly improve the efficiency of various conductor-related operations, reduce labor costs and operational risks, and are becoming an indispensable tool for modern engineering operations.
[0003] Currently, various types of wire storage devices exist for wire drones. Some have simple structures, performing only basic wire winding functions. Others lack effective protection and organization mechanisms, making it difficult to properly protect wires during storage. Furthermore, most devices lack a rational storage space layout, failing to adequately accommodate wires of varying lengths and specifications. This leads to numerous inconveniences during actual use and compromises the overall operational efficiency of the wire drone.
[0004] Typically, existing wire storage devices rely on a simple mechanical structure to rotate a storage shaft during reeling, allowing the wire to be wound around the shaft. After being pulled from the drone, the wire is directly connected to the inlet of the storage device, where it is gradually wound as the shaft rotates. When unwinding, the drone's traction is often used to pull the wire from the storage device. This lacks precise control over the unwinding process and effective guidance of the wire, which can easily cause wire disarray and wear.
[0005] Existing technologies have significant shortcomings in wire storage. Due to the lack of a dedicated, uniform storage design, wires often accumulate and tangle in localized areas of the storage column, resulting in irregular storage. During the retraction and deployment process, without a proper guidance and lifting and lowering mechanism, wires easily become entangled, increasing the risk of damage from friction. Furthermore, once entangled, it is difficult to quickly untangle, which not only impacts work progress but can also damage the wire's insulation or internal fibers due to excessive friction, reducing the wire's service life and signal transmission quality. Utility Model Content
[0006] Based on this, the purpose of the utility model is to provide a wire retracting device for a wire drone to solve the technical problems that the wires of the existing wire drones are inconvenient to retract and easily entangled and damaged during retraction.

[0011] The present invention is further configured such that a guide protrusion cooperating with the reciprocating thread is provided on the outer side of the lifting slip ring.
[0012] By adopting the above technical solution, the provided guide protrusion cooperates with the reciprocating thread. When the lifting slip ring rotates, the guide protrusion rotates along the thread of the reciprocating thread, thereby driving the lifting slip ring to lift and reciprocate.

[0018] By adopting the above technical solution, the optical fiber is passed through the bottom of the base so that the optical fiber can be connected to the control device.
[0019] To sum up, the utility model drives the crown gear through the transmission gear of the motor, drives the support rod, the limit rod, and the crossbeam to rotate, and the guide protrusion cooperates with the reciprocating thread during rotation. When the lifting slip ring rotates, the guide protrusion rotates along the thread of the reciprocating thread, thereby driving the lifting slip ring to lift and reciprocate, so that the optical fiber is evenly stored up and down on the outside of the storage column, avoiding local stacking.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0027] The following describes an embodiment of the present invention based on its overall structure.
[0028] A wire retracting and releasing device for a wire drone, including a wire retracting and releasing device for a wire drone, including a shell 1, a top plate 3 is provided on the top of the shell 1, a base 2 is provided at the bottom of the shell 1, a fixing column 15 is provided on the top of the base 2, a storage column 12 is provided on the top of the fixing column 15, a reciprocating thread 6 is provided on the inner wall of the shell 1, the bottom end of the outer side of the storage column 12 is rotatably connected to a crown gear 13, the top of the storage column 12 is rotatably connected to a crossbeam 5, a pair of support rods parallel to the crossbeam 5 are provided on the outer side of the crown gear 13, a pair of limiting rods 14 are connected between the crossbeam 5 and the support rods, a lifting slip ring 10 that cooperates with the reciprocating thread 6 is slidably sleeved on the outer side of the limiting rod 14, a first guide wheel 11 is provided on the top of the crossbeam 5, a second guide wheel 7 is provided inside the crossbeam 5 near the limiting rod 14, and a third guide wheel 8 is provided on the inner wall of the lifting slip ring 10.
[0029] Pass the optical fiber 4 through the removed top plate 3, then through the first guide wheel 11, the second guide wheel 7, and the third guide wheel 8, and then through the storage column 12, the fixing column 15, and the base 2. After exiting the bottom of the base 2, connect it to the external control device to check the connectivity. Optionally, add a fixing clip to the bottom of the base 2 to assist in securing the optical fiber 4.
[0030] After fixing, pull the optical fiber 4 and install the top plate 3 to the top of the housing 1. The motor 16 can be used in combination with a control switch as needed. Optionally, a crank can be used instead of the motor 16. When a crank is used, the crank should be used with a clutch structure. For example, when a crank is used, the crank can be pulled to control the degree of engagement between the transmission gear and the crown gear 13. When the line is released, the optical fiber 4 is brought out by the drone, which drives the support rod, the limit rod 14, and the crossbeam 5 to rotate and pull the optical fiber 4 out of the through hole in the middle of the top plate 3. At this time, the crank is pulled out, and the transmission gear and the crown gear 13 should be disengaged to avoid applying too much resistance to the optical fiber 4. Among them, when the movement of the motor 16 is not associated with the drone flight control, that is, when the motor 16 cannot automatically rotate and release the line according to the signal of the drone flight control, a pulling structure should be added to the fixed structure of the motor. When the line is released, the transmission gear and the crown gear 13 should be disengaged to avoid applying too much resistance to the optical fiber 4.
[0031] When winding, the motor 16 drives the crown gear 13 through the transmission gear, drives the support rod to rotate, and then drives the limit rod 14 to rotate, thereby driving the crossbeam 5 to rotate, and at the same time drives the first guide wheel, the second guide wheel and the third guide wheel to rotate. At this time, the optical fiber 4 rotates accordingly and is wound on the storage column 12. During rotation, the guide protrusion 9 cooperates with the reciprocating thread 6. When the lifting slip ring 10 rotates, the guide protrusion 9 rotates along the thread of the reciprocating thread 6, thereby driving the lifting slip ring 10 to rise and fall back and forth. The optical fiber 4 is evenly stored up and down on the outside of the storage column 12 to avoid local stacking. Among them, the first guide wheel, the second guide wheel and the third guide wheel guide the retraction and release direction of the optical fiber 4 and reduce the friction on the optical fiber 4.
[0032] The present invention is further configured such that a reinforcement ring is provided at the bottom of the support rod, and the structural strength of the support rod is increased by the provided reinforcement ring.
[0033] The present invention is further configured such that a guide protrusion 9 cooperating with the reciprocating thread 6 is provided on the outer side of the lifting slip ring 10. By cooperating with the reciprocating thread 6, the guide protrusion 9 rotates along the thread of the reciprocating thread 6 when the lifting slip ring 10 rotates, thereby driving the lifting slip ring 10 to lift and reciprocate.
[0034] The present invention is further configured such that a motor 16 is provided inside the base 2, and a transmission gear cooperating with the crown gear 13 is provided at the output end of the motor 16. The transmission gear is driven to rotate by the motor 16, thereby driving the crown gear 13 to rotate, thereby driving the support rod, the limit rod 14, and the crossbeam 5 to rotate.
[0035] The present invention is further configured such that an optical fiber 4 cooperating with the first guide wheel 11 , the second guide wheel 7 , and the third guide wheel 8 is provided on the outside of the storage column 12 , and a control signal is transmitted through the provided optical fiber 4 .
[0036] The present invention is further configured such that the optical fiber 4 passes through the storage column 12, the fixing column 15, the base 2, and comes out from the bottom of the base 2. By passing the optical fiber 4 out from the bottom of the base 2, the optical fiber 4 can be connected to the control device.

The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
