Description

Technical Field

[0001] This utility model relates to the technical field of anti-sway connection devices, and in particular to an anti-sway connection device for installing electromagnetic receiving coils for unmanned aerial vehicles. Background Technology

[0002] An electromagnetic receiving coil is an inductive element used to sense external electromagnetic fields and convert them into electrical signals. It is widely used in electromagnetic detection, wireless communication, electromagnetic compatibility testing, geological exploration, and other fields. Its basic working principle is based on Faraday's law of electromagnetic induction: when the external magnetic field changes, an induced electromotive force is generated in the coil, thereby achieving the reception of electromagnetic signals. Electromagnetic receiving coils are typically made of highly conductive materials (such as copper wire) and are characterized by high sensitivity and fast response speed. Their structure and size significantly affect the frequency range, intensity, and directionality of the received signal. In UAV-borne systems, they are often an important component of the detection equipment, requiring a combination of anti-interference design and stable installation methods to ensure reception accuracy.

[0003] As a crucial component for wireless power transmission or signal reception in drones, the installation method of the electromagnetic receiving coil directly affects the overall system performance and stability. Currently, most drones use traditional nylon rope suspension or rigid connectors to fix the electromagnetic receiving coil. Nylon rope is widely used due to its light weight and ease of processing, but its high elasticity makes the coil prone to significant swaying when faced with airflow disturbances and aircraft vibrations during flight. While rigid connectors provide high fixing strength, they lack effective vibration absorption capabilities and may even cause or exacerbate coil swaying in complex airflow environments. Therefore, existing installation methods have certain limitations in terms of stability and vibration resistance.

[0004] Based on this, we propose an anti-sway connection device for mounting electromagnetic receiver coils for UAVs to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide an anti-sway connection device for installing electromagnetic receiving coils of drones, which can solve the problem that the electromagnetic receiving coils of drones sway and swing due to airflow disturbances and body vibrations during flight, caused by traditional nylon rope suspension or rigid connector fixing methods, thus affecting the stability of wireless energy transmission and signal reception.

[0007] To solve the above technical problems, this utility model provides an anti-sway connection device for installing an electromagnetic receiving coil for a drone, which adopts the following technical solution: it includes a drone body, a hoisting assembly is provided at the bottom of the drone body, an electromagnetic coil is connected to the bottom of the hoisting assembly, the hoisting assembly includes a hoisting adjuster, and two hoisting ropes are drivenly connected to the bottom of the hoisting adjuster.

[0008] The top of the electromagnetic coil is equipped with a hoisting bracket, and two sets of shock-absorbing connectors are provided at both ends of the top of the hoisting bracket.

[0009] Optionally, the shock-absorbing connector includes a telescopic link, one end of which is fitted with a rope connecting cap, and a compression spring is also sleeved and connected to the outside of the telescopic link.

[0010] Optionally, the hoisting adjuster includes a mounting plate, and a connecting cover plate is provided at the bottom of the mounting plate.

[0011] Optionally, motor drive boxes are installed at both ends of the mounting plate, and a connecting groove is provided between the two sets of motor drive boxes. The connecting groove matches the structure of the connecting cover plate, and the connecting groove and the connecting cover plate are engaged. Two sets of winding wheels are connected inside the connecting groove through bearings, and the two sets of winding wheels are connected to the two sets of motor drive boxes by transmission.

[0012] Optionally, two sets of roller covers are installed at the bottom of the connecting cover plate. The roller covers are matched with the winding roller structure, and the bottom of the two sets of roller covers are respectively provided with wire through holes.

[0013] Optionally, the lifting rope is made of two strands of silicone damping rope spirally wound together, and the lifting rope has an overall spiral twisted structure.

[0014] In summary, this utility model has at least one of the following beneficial effects:

[0015] 1. The anti-sway connection device designed in this scheme uses a hoisting rope made of two strands of silicone damping rope spirally wound together. This effectively absorbs and dissipates vibration energy. This structural design not only provides good flexibility for the electromagnetic receiving coil, but also has excellent damping performance. It can effectively absorb impact energy under the action of vibration and airflow disturbance, thereby reducing the sway amplitude of the electromagnetic receiving coil. Through the above structural design, stable support for the electromagnetic receiving coil is achieved in complex airflow environments, ensuring its signal reception accuracy and stability during flight. This improves the reliability of UAV applications in electromagnetic detection, wireless communication and other fields. At the same time, the shock-absorbing connector, through the cooperation between the telescopic link and the compression spring, can effectively reduce the sway of the electromagnetic receiving coil during UAV flight, ensuring its stability and reliability in complex airflow environments, further enhancing the shock absorption and anti-sway effect of the device.

[0016] 2. The anti-sway connection device designed in this scheme, through the cooperation of the motor drive box and the winding reel in the hoisting adjuster, can precisely adjust the length of the hoisting rope. When the motor drive box is running, it can drive the winding reel, which is wound with the hoisting rope inside, to rotate synchronously, realizing the hoisting rope winding and unwinding operations. Through the above adjustment mechanism, the electromagnetic receiving coil can remain stable under different flight attitudes, adapting to different flight environments and mission requirements. This structural design not only improves the flexibility and practicality of the device, but also expands its application range in the field of anti-sway connection device technology, realizing precise position control of the electromagnetic receiving coil, ensuring its stability and reliability under various flight conditions. Through the structural design of the connecting cover plate and the winding reel cover, it can also effectively prevent the hoisting rope from shifting or jamming during the winding process, ensuring the stability of the hoisting rope during winding and unwinding, and improving the reliability and service life of the device.

[0024] 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.

[0025] Example: Refer to Figures 1 to 5 This utility model provides an embodiment of an anti-sway connection device for mounting an electromagnetic receiving coil on a drone. The device includes a drone body 1, a hoisting assembly 2 at the bottom of the drone body 1, and an electromagnetic coil 3 connected to the bottom of the hoisting assembly 2. The hoisting assembly 2 includes a hoisting adjuster 4, with two hoisting ropes 5 connected to the bottom of the hoisting adjuster 4. A hoisting bracket 6 is mounted on the top of the electromagnetic coil 3, and two sets of shock-absorbing connectors 7 are provided at both ends of the top of the hoisting bracket 6. This anti-sway connection device, through the synergistic effect of the hoisting adjuster 4, the two hoisting ropes 5, and the shock-absorbing connectors 7, provides good flexibility for the electromagnetic coil 3 mounted on the bottom of the drone body 1. The shock absorber connector 7 can effectively absorb impact energy under the influence of vibration and airflow disturbance, and can effectively reduce the swaying of the electromagnetic receiving coil during the flight of the drone, ensuring its stability and reliability in complex airflow environments. The shock absorber connector 7 includes a telescopic link 8, one end of which is equipped with a rope connection cover 9, and a compression spring 10 is also sleeved and connected to the outside of the telescopic link 8. The shock absorber connector 7 is used in cooperation between the telescopic link 8 and the compression spring 10. The telescopic link 8 and the compression spring 10 can absorb vibration through their elastic deformation, which can effectively reduce the swaying of the electromagnetic receiving coil during the flight of the drone, ensuring its stability and reliability in complex airflow environments.

[0026] The hoisting adjuster 4 includes a mounting plate 11. A connecting cover plate 12 is provided at the bottom of the mounting plate 11. By adding the connecting cover plate 12 to the bottom of the mounting plate 11, the hoisting rope 5 can be effectively prevented from shifting or getting stuck during the winding process. Motor drive boxes 13 are installed at both ends of the mounting plate 11. A connecting groove 14 is provided between the two sets of motor drive boxes 13. The connecting groove 14 matches the structure of the connecting cover plate 12 and the connecting groove 14 and the connecting cover plate 12 are engaged. Two sets of winding wheels 15 are connected to the inside of the connecting groove 14 through bearings. The two sets of winding wheels 15 are connected to the two sets of motor drive boxes 13. The two sets of motor drive boxes 13 and two sets of motor drive boxes 13 are connected by a transmission mechanism. When the motor drive box 13 is powered off, it can drive the two sets of motor drive boxes 15, which are internally wound with hoisting ropes 5, to rotate synchronously. When the two sets of motor drive boxes 15 rotate clockwise, they can release the two hoisting ropes 5 that are hoisted at the bottom of the UAV body 1. When the two sets of motor drive boxes 15 rotate counterclockwise, they can retract the two hoisting ropes 5 that are hoisted at the bottom of the UAV body 1.

[0027] Two sets of roller covers 16 are installed at the bottom of the connecting cover plate 12. The roller covers 16 are structurally matched with the take-up roller 15. The bottom of the two sets of roller covers 16 are respectively provided with wire holes 17. Through the structural design of matching the roller covers 16 with the take-up roller 15, the lifting rope 5 can be effectively prevented from shifting or getting stuck during the winding process, ensuring the stability of the lifting rope 5 during the winding and release process. The lifting rope 5 is made of two strands of silicone damping rope 18 spirally wound together. The lifting rope 5 has a spiral twisted structure. This structural design of the lifting rope 5 not only provides good flexibility for the electromagnetic coil 3 suspended at the bottom of the UAV body 1, but also has excellent damping performance, which can effectively absorb the impact energy under the action of vibration and airflow disturbance.

[0028] Working Principle: The anti-sway connection device designed in this scheme mainly consists of the UAV body 1, the hoisting assembly 2, and the electromagnetic coil 3. The hoisting assembly 2 includes a hoisting adjuster 4 and two hoisting ropes 5. The hoisting ropes 5 are made of two silicone damping ropes 18 spirally wound together, and the hoisting ropes 5 have an overall spiral twisted structure. This structural design of the hoisting ropes 5 not only provides good flexibility for the electromagnetic coil 3 hoisted at the bottom of the UAV body 1, but also has excellent damping performance, which can effectively absorb the impact energy under the action of vibration and airflow disturbance, thereby reducing the self-damping effect of the electromagnetic coil 3. The sway amplitude is reduced by the shock-absorbing connector 7 installed on the top of the hoisting bracket 6. When the UAV body 1 is subjected to airflow disturbance or body vibration, the shock-absorbing connector 7 works in conjunction with the telescopic link 8 and the compression spring 10. The telescopic link 8 and the compression spring 10 can absorb vibration through their elastic deformation, which can effectively reduce the sway of the electromagnetic receiving coil during the flight of the UAV and ensure its stability and reliability in complex airflow environments. Through the synergistic effect of the above structures, the device can provide multi-level shock absorption and anti-sway functions for the electromagnetic coil 3 suspended at the bottom of the UAV body 1.

[0029] The anti-sway connection device designed in this scheme uses a motor drive box 13 and a winding wheel 15 installed on the mounting plate 11. The two winding wheels 15 are connected to the two sets of motor drive boxes 13 via a transmission connection. When the motor drive box 13 is powered off, it can drive the two sets of winding wheels 15, which have the hoisting rope 5 wound inside, to rotate synchronously. When the two sets of winding wheels 15 rotate clockwise, they can release the two hoisting ropes 5 suspended at the bottom of the UAV body 1. When the two sets of winding wheels 15 rotate counterclockwise, they can release the ropes 5 suspended at the bottom of the UAV body 1. The two lifting ropes 5 are wound up. As mentioned above, the lifting adjuster 4 can precisely adjust the length of the two lifting ropes 5 through the cooperation between the motor drive box 13 and the winding wheel 15, ensuring that the electromagnetic coil 3 remains stable under different flight attitudes. With the structural design of the connecting cover plate 12 and the winding wheel cover 16, the stability of the device during operation can be further enhanced, effectively preventing the lifting ropes 5 from shifting or getting stuck during the winding process. This can improve the flexibility and practicality of the device in the field of anti-sway connection device technology.
