Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, specifically a multi-functional UAV take-off and landing platform and a multi-functional UAV system. Background Technology

[0002] With the continuous development of drone technology, drones are being used more and more widely in various fields. In practical applications, the drone take-off and landing platform plays a crucial role. Currently, most drone take-off and landing platforms have limited functionality, only meeting the basic take-off and landing needs of drones.

[0003] In certain scenarios, such as power line inspection and firefighting, drones are required to possess multiple functions. For example, in the event of a fire, drones need to be able to quickly take off to conduct fire reconnaissance and carry out firefighting operations; in winter, facilities are prone to icing, requiring drones to perform de-icing work. However, existing take-off and landing platforms cannot quickly replace drones with different functions, nor do they possess firefighting or de-icing capabilities, resulting in low work efficiency and an inability to meet complex and ever-changing practical needs. Furthermore, existing take-off and landing platforms lack environmental adaptability and struggle to operate stably in harsh environments. Summary of the Invention

[0004] To address the problem that existing drone take-off and landing platforms cannot quickly adapt to drones with different functions, this invention provides a multi-functional drone take-off and landing platform and a multi-functional drone system. The multi-functional drone take-off and landing platform optimizes and integrates operational material supply functions, enabling rapid drone replacement and task switching. It can also provide automatic replenishment of fire extinguishing agents and de-icing agents for drones, and has advantages such as high operational efficiency and multiple functions.

[0005] The technical solution adopted by the embodiments of the present invention to solve its technical problem is as follows:

[0006] A multi-functional drone take-off and landing platform includes a drone take-off and landing platform and a base arranged vertically. The drone take-off and landing platform is used for drone take-off and landing, and the base is equipped with a de-icing agent container and a fire extinguishing agent container. The de-icing agent container can supply de-icing agent to the drone, and the fire extinguishing agent container can supply fire extinguishing agent to the drone.

[0007] A multi-functional unmanned aerial vehicle (UAV) system includes a UAV and the aforementioned multi-functional UAV take-off and landing platform. The UAV is a fire-fighting and de-icing UAV and an inspection UAV. The fire-fighting and de-icing UAV includes a second infusion tube plug and a second charging cable plug. When the fire-fighting and de-icing UAV lands on the UAV take-off and landing platform, the first infusion tube plug and the first charging cable plug are exposed, and the second infusion tube plug and the first infusion tube plug are correspondingly plugged in, and the second charging cable plug and the first charging cable plug are correspondingly plugged in. A grappling hook mechanism can secure the fire-fighting and de-icing UAV. When the inspection UAV lands on the UAV take-off and landing platform, the first infusion tube plug and the first charging cable plug are hidden, and the grappling hook mechanism can secure the inspection UAV.

[0008] The beneficial effects of the embodiments of the present invention are:

[0009] 1. Highly efficient and rapid drone replacement: The unique quick-release water pipe structure allows for drone replacement within 10 seconds, significantly reducing replacement time compared to traditional methods. This reduces the total time from drone landing to takeoff for a new mission to within 3 minutes, greatly improving mission switching efficiency. In time-sensitive scenarios such as emergency rescue and power restoration, drones can be quickly deployed to new missions, seizing the best opportunity for action.

[0010] 2. Highly integrated functional design: Multiple functions such as fire extinguishing, de-icing, and inspection are integrated onto a single platform. This changes the traditional situation of fragmented functions and independent equipment. It not only reduces the equipment's footprint but also simplifies the operation process. Operators can complete the entire process simply through a touchscreen, reducing operational complexity and the risk of human error, and improving the overall stability and reliability of operations.

Regarding the material, weight, size, angle, and parameters of the components, those skilled in the art can determine or replace them according to actual needs or a limited number of experiments. Example 1

[0023] like Figures 1 to 6 As shown, the multi-functional UAV take-off and landing platform described in this embodiment includes a UAV take-off and landing platform 13 and a base 1 arranged vertically. The UAV take-off and landing platform 13 can provide UAV 48 with take-off and landing. The base 1 is provided with a de-icing agent container 2 and a fire extinguishing agent container 5. The de-icing agent container 2 can supply de-icing agent to the UAV 48, and the fire extinguishing agent container 5 can supply fire extinguishing agent to the UAV 48.

[0024] The drone 48 can be a fire-fighting and de-icing drone 15 or an inspection drone 16. The multi-functional drone take-off and landing platform integrates multiple functions such as fire extinguishing, de-icing, and inspection operations onto the same platform. This changes the traditional situation of dispersed functions and independent equipment. It not only reduces the equipment's footprint but also simplifies the operation process. Operators can complete the entire operation through a touch screen, reducing operational complexity and the risk of human error, and improving the overall stability and reliability of the operation.

[0025] As one possible implementation method, such as Figures 3 to 4 As shown, the drone landing platform 13 has a horizontal plate-like structure. The drone landing platform 13 is equipped with a first infusion tube plug 18, a first charging cable plug 22 and a hook mechanism 30. The first infusion tube plug 18 and the first charging cable plug 22 can be connected to the drone 48. The first infusion tube plug 18 and the first charging cable plug 22 can also be exposed or hidden. The hook mechanism 30 can fix or release the drone 48.

[0026] The first infusion tube plug 18 supplies de-icing agent or fire extinguishing agent to the drone 48, and the first charging cable plug 22 supplies electrical energy to the drone 48. The grappling hook mechanism 30 secures the drone 48 to the drone landing platform 13 when it lands, and releases it when the drone 48 needs to take off, allowing it to detach from the platform 13.

[0027] As one possible implementation method, such as Figures 3 to 4As shown, the UAV landing platform 13 has a ring structure. A quick-release module 14 is matched in the middle of the UAV landing platform 13. The first infusion tube plug 18 and the first charging cable plug 22 are both located on the quick-release module 14. The quick-release module 14 contains a housing 49 and an internal cavity 50. The housing 49 contains a top plate 51, a side plate 52 and a bottom plate 53 connected from top to bottom. The quick-release module 14 also contains a platform flip cover 29. The platform flip cover 29 is connected to the top plate 51 by a spring hinge 28. The upper surface of the UAV landing platform 13, the upper surface of the top plate 51 and the upper surface of the platform flip cover 29 are located in the same horizontal plane. The first infusion tube plug 18 and the first charging cable plug 22 are connected and fixed as one piece. The first infusion tube plug 18 is inserted into the top plate 51 and is adjacent to the platform flip cover 29.

[0028] The spring hinge 28 includes a hinge axis, which is horizontal and located at the connection between the platform cover 29 and the top plate 51. The platform cover 29 can rotate upwards or downwards around the hinge axis and return to a horizontal position after rotation. When the platform cover 29 is closed, its upper surface is flush with the upper surface of the top plate 51. When the platform cover 29 is open, the first infusion tube plug 18 and the first charging cable plug 22 can be exposed above the top plate 51 or hidden inside the internal cavity 50 by moving or rotating them.

[0029] As one possible implementation method, such as Figure 6 As shown, both the first infusion tube plug 18 and the first charging cable plug 22 are quick-connect female connectors. The outlet ends of the first infusion tube plug 18 and the first charging cable plug 22 are facing upwards. The first charging cable plug 22 is connected and fixed to the first infusion tube plug 18 by a sealing ring 20 and a sealing screw 21. The multi-functional UAV take-off and landing platform also includes a power supply and a platform-end charging cable 19. The two ends of the platform-end charging cable 19 are connected to the first charging cable plug 22 and the power supply, respectively. The platform-end charging cable 19 passes through the sealing ring 20 and the first infusion tube plug 18. The platform-end charging cable 19 can be a coiled wire that can be automatically retracted.

[0030] As one possible implementation method, such as Figures 3 to 4As shown, the hook mechanism 30 is basically located within the internal cavity 50. The hook mechanism 30 includes a servo motor 31, a transmission belt 32, a first transmission unit 46, and a second transmission unit 47. The first transmission unit 46 includes a first gear 39, a first transition shaft 33, a first reducer 34, a first synchronous belt 35, and a first transmission shaft 36 connected in sequence. A first hook 37 and a second hook 38 are fixedly connected to the first transmission shaft 36. The first hook 37 and the second hook 38 are spaced apart along the axial direction of the first transmission shaft 36. The second transmission unit 47 includes a second gear 40, a second reducer 41, a second synchronous belt 45, and a second transmission unit 47 connected in sequence. The belt 42 and the second drive shaft 43 are connected together. The third hook 44 and the fourth hook 45 are fixedly connected to the second drive shaft 43. The third hook 44 and the fourth hook 45 are spaced apart along the axial direction of the second drive shaft 43. The first gear 39 and the second gear 40 are meshed together. The first drive shaft 36 and the second drive shaft 43 are both horizontal. The first drive shaft 36 and the second drive shaft 43 extend in the front-back direction. The first drive shaft 36 and the second drive shaft 43 are mirror images of each other. The first drive shaft 36 and the second drive shaft 43 are spaced apart in parallel to each other. The servo motor 31 is directly or indirectly connected to the first transition shaft 33 through the drive belt 32.

[0031] The servo motor 31 can synchronously drive the first pawl 37 and the second pawl 38 to rotate around the axis of the first drive shaft 36, and the third pawl 44 and the fourth pawl 45 to rotate around the axis of the second drive shaft 43. During rotation, the rotation speed of the first drive shaft 36 is the same as that of the second drive shaft 43, and the rotation direction of the first drive shaft 36 is opposite to that of the second drive shaft 43. The first pawl 37, the second pawl 38, the third pawl 44, and the fourth pawl 45 can all pass through the top plate 51. The first pawl 37, the second pawl 38, the third pawl 44, and the fourth pawl 45 can rotate upward and extend out of the top plate 51, and the first pawl 37, the second pawl 38, the third pawl 44, and the fourth pawl 45 can fix the skid of the UAV 48. The first hook 37, the second hook 38, the third hook 44, and the fourth hook 45 can rotate downwards and retract into the internal cavity 50, and the first hook 37, the second hook 38, the third hook 44, and the fourth hook 45 can release the skid of the drone 48.

[0032] As one possible implementation, a high-pressure infusion pump 10 and a three-way solenoid valve 8 are provided on the base 1. The three-way solenoid valve 8 has one outlet and two inlets. The outlet ends of the de-icing agent container 2 and the fire extinguishing agent container 5 are both located at the bottom. The outlet end of the de-icing agent container 2 is connected to one inlet of the three-way solenoid valve 8, and the outlet end of the fire extinguishing agent container 5 is connected to the other inlet of the three-way solenoid valve 8. An infusion tube reel 12 is connected below the UAV landing platform 13. The infusion tube reel 12 contains an infusion coil and an automatic winding mechanism. The automatic winding mechanism can automatically retract the infusion coil after it is released. The platform-end charging cable 19 is arranged side by side with the infusion coil. The platform-end charging cable 19 can be sleeved inside the infusion coil, or it can be located outside the infusion coil.

[0033] like Figure 1 , Figure 2 and Figure 5 As shown, the inlet end of the high-pressure infusion pump 10 is connected to the outlet end of the three-way solenoid valve 8 via the infusion pump inlet pipe 9. The outlet end of the high-pressure infusion pump 10 is connected to the inlet end of the infusion tube reel 12 (infusion coil) via the infusion pump outlet pipe 11. The outlet end of the infusion tube reel 12 (infusion coil) is connected to the first infusion tube plug 18. The first infusion tube plug 18 and the first charging cable plug 22 can be retracted and extended synchronously. A through hole 58 is provided on the side plate 52 or the bottom plate 53, through which the infusion coil of the infusion tube reel 12 passes. By controlling the high-pressure infusion pump 10 and the three-way solenoid valve 8, it is possible to select that the de-icing agent container 2 supplies de-icing agent to the drone 48, or to select that the fire extinguishing agent container 5 supplies fire extinguishing agent to the drone 48.

[0034] As an alternative implementation, the base 1 is also equipped with a control unit 17. The high-pressure infusion pump 10 and the three-way solenoid valve 8 are both connected to the control unit 17. The control unit 17 can control the high-pressure infusion pump 10 and the three-way solenoid valve 8. For example, the control unit 17 can control the on / off state of the high-pressure infusion pump 10, and it can also independently control the on / off state of the two inlets of the three-way solenoid valve 8. In this way, the control unit 17 enables the de-icing agent container 2 to supply de-icing agent to the drone 48, and it also enables the fire extinguishing agent container 5 to supply fire extinguishing agent to the drone 48.

[0035] like Figure 1 As shown, the upper part of the de-icing agent container 2 is equipped with a de-icing agent filling port 3 and a de-icing agent level indicator 4, and the upper part of the fire extinguishing agent container 5 is equipped with a fire extinguishing agent filling port 6 and a fire extinguishing agent level indicator 7. The de-icing agent filling port 3 is used to add de-icing agent into the de-icing agent container 2, and the de-icing agent level indicator 4 is used to display the content of de-icing agent in the de-icing agent container 2. The fire extinguishing agent filling port 6 is used to add fire extinguishing agent into the fire extinguishing agent container 5, and the fire extinguishing agent level indicator 7 is used to display the content of fire extinguishing agent in the fire extinguishing agent container 5.

[0036] The following describes a multi-functional unmanned aerial vehicle (UAV) system, which includes a UAV 48 and the aforementioned multi-functional UAV take-off and landing platform. The UAV 48 is a fire-fighting and ice-melting UAV 15 and an inspection UAV 16. The fire-fighting and ice-melting UAV 15 includes a second infusion tube plug 26 and a second charging cable plug 24. Either the fire-fighting and ice-melting UAV 15 or the inspection UAV 16 can be selected to land on the UAV take-off and landing platform 13 as needed.

[0037] When the fire-fighting ice-melting drone 15 lands on the drone landing platform 13, the first infusion tube plug 18 and the first charging cable plug 22 are both exposed. The first infusion tube plug 18 is plugged into (or snapped into) the top plate 51. The second infusion tube plug 26 is plugged into the first infusion tube plug 18, and the second charging cable plug 24 is plugged into the first charging cable plug 22. The hook mechanism 30 can fix the fire-fighting ice-melting drone 15. At this time, the fire-fighting ice-melting drone 15 cannot detach from the drone landing platform 13.

[0038] When the inspection drone 16 lands on the drone landing platform 13, the first infusion tube plug 18 is detached from the top plate 51. Both the first infusion tube plug 18 and the first charging cable plug 22 are hidden. The hook mechanism 30 can fix the inspection drone 16.

[0039] The fire-fighting and ice-melting drone 15 also includes an aircraft-end charging cable 23 and an aircraft-end infusion tube 25. A second charging cable plug 24 is located at one end of the aircraft-end charging cable 23, and the other end of the aircraft-end charging cable 23 is directly or indirectly connected to the flight power output mechanism of the fire-fighting and ice-melting drone 15. The aircraft-end charging cable 23 can supply electrical energy to the flight power output mechanism of the fire-fighting and ice-melting drone 15. A second infusion tube plug 26 is located at one end of the aircraft-end infusion tube 25, and the other end of the aircraft-end infusion tube 25 is connected to a nozzle 27. Both the second infusion tube plug 26 and the second charging cable plug 24 can be quick-connect male connectors.

[0040] The working process of the multi-functional unmanned aerial vehicle system is described below.

[0041] Before use, add de-icing agent to de-icing agent container 2 through de-icing agent filling port 3, and add fire extinguishing agent to fire extinguishing agent container 5 through fire extinguishing agent filling port 6. Observe the liquid level filling status through de-icing agent level display 4 and fire extinguishing agent level display 7 respectively. Base 1 can be mounted on any mobile platform.

[0042] When used for firefighting or de-icing operations, the firefighting and de-icing drone 15 lands on the quick-release module 14 of the drone landing platform 13. The first infusion tube plug 18 and the second infusion tube plug 26 are connected accordingly, and the first charging cable plug 22 and the second charging cable plug 24 are connected accordingly. Power is supplied to the firefighting and de-icing drone 15 sequentially through the platform-end charging cable 19 and the aircraft-end charging cable 23. The hook mechanism 30 releases the firefighting and de-icing drone 15. The firefighting and de-icing drone 15 takes off, and the first infusion tube plug 18 and the first charging cable plug 22 fly with the firefighting and de-icing drone 15, and the infusion coil of the infusion tube reel 12 is released synchronously.

[0043] Once the fire-fighting de-icing drone 15 reaches the required location, it selects to open or close the inlet of the three-way solenoid valve 8 corresponding to the outlet of the de-icing agent container 2 and the fire extinguishing agent container 5, and starts the high-pressure infusion pump 10, depending on the needs of fire-fighting or de-icing operations. For example, when fire-fighting operations are required, the inlet of the three-way solenoid valve 8 corresponding to the fire extinguishing agent container 5 is opened, and the inlet of the three-way solenoid valve 8 corresponding to the de-icing agent container 2 is closed. The high-pressure infusion pump 10 delivers the fire extinguishing agent from the fire extinguishing agent container 5 to the fire-fighting de-icing drone 15, and the fire extinguishing agent is sprayed out by the nozzle 27. When de-icing operations are required, the inlet of the three-way solenoid valve 8 corresponding to the de-icing agent container 2 is opened, and the inlet of the three-way solenoid valve 8 corresponding to the fire extinguishing agent container 5 is closed. The high-pressure infusion pump 10 delivers the de-icing agent from the de-icing agent container 2 to the fire-fighting de-icing drone 15, and the de-icing agent is sprayed out by the nozzle 27.

[0044] After the operation is completed, the fire-fighting ice-melting drone 15 returns and lands on the drone landing platform 13. The first infusion tube plug 18 is connected to the second infusion tube plug 26, the first charging cable plug 22 is connected to the second charging cable plug 24, and the hook mechanism 30 re-fixes the fire-fighting ice-melting drone 15.

[0045] When an inspection is required, the hook mechanism 30 releases the fire-fighting ice-melting drone 15, manually separating the first infusion tube plug 18 from the second infusion tube plug 26, and the first charging cable plug 22 from the second charging cable plug 24. Then, the fire-fighting ice-melting drone 15 is removed from the drone landing platform 13. The platform cover 29 is flipped up, and the first infusion tube plug 18 and the first charging cable plug 22 are removed and hidden within the internal cavity 50. The platform cover 29 automatically springs back to a horizontal position via the spring hinge 28, restoring the drone landing platform 13 to a flat state. The inspection drone 16 is placed on the drone landing platform 13. After takeoff, the inspection drone 16 can perform inspection tasks as needed. After the inspection task is completed, the inspection drone 16 returns and lands on the drone landing platform 13, and the hook mechanism 30 re-secures the inspection drone 16.

[0046] When firefighting or de-icing operations are required again, the inspection drone 16 can be removed from the drone landing platform 13, and the fire-fighting and de-icing drone 15 can be installed on the quick-release module 14 of the drone landing platform 13.

[0047] The quick-release structure allows the drone to be replaced in under 10 seconds, significantly reducing replacement time compared to traditional methods. This reduces the total time from landing to takeoff for a new mission to within 3 minutes, greatly improving mission switching efficiency. In time-sensitive scenarios such as emergency rescue and power restoration, drones can be quickly deployed to new missions, seizing the best opportunity to respond. Example 2

[0048] This embodiment is a modification of Embodiment 1. The main difference between this embodiment and Embodiment 1 is:

[0049] As one possible implementation method, such as Figure 1 , Figure 2 and Figure 7 As shown, the multi-functional UAV take-off and landing platform also includes a robotic arm 54. One end of the robotic arm 54 is connected to the base 1 or the UAV take-off and landing platform 13. The other end of the robotic arm 54 can be connected to a mechanical ice scraping device 55 and a hot air drying device 56. The UAV take-off and landing platform 13 and the UAV 48 can be equipped with an ultrasonic de-icing device 57.

[0050] The mechanical ice scraper 55 and the hot air drying device 56 can be used together. When ice is detected on the surface of the multi-functional UAV take-off and landing platform or the UAV 48, the robotic arm 54 drives the scraper of the mechanical ice scraper 55 to remove the ice layer, while the small hot air drying device 56 dries the remaining ice and damp surface. This eliminates the need for de-icing agents, reducing liquid consumption and environmental pollution, making it suitable for mild icing scenarios.

[0051] Ultrasonic de-icing devices 57 are installed on key areas of the drone landing platform 13 and the drone 48. These devices utilize high-frequency vibrations generated by an ultrasonic generator to cause the ice layer to resonate, break, and fall off. Ultrasonic de-icing is non-contact, non-corrosive, and does not damage the drone surface. It can be combined with a small amount of de-icing agent spraying to improve the de-icing effect.

[0052] The first infusion tube plug 18 can be moved or rotated manually, or it can be moved or rotated pneumatically. For example, the pneumatic system can push the first infusion tube plug 18 to connect with the second infusion tube plug 26 and the first charging cable plug 22 to connect with the second charging cable plug 24, forming a mechanical lock and tubing connection (which can also be used for material replenishment). When disassembly is required, the pneumatic device retracts the plug, achieving quick separation, combining connection stability and quick replacement.

[0053] Dry powder fire extinguishing replaces perfluorohexanone: The perfluorohexanone storage tank is replaced with a dry powder storage tank, and a screw conveyor is used to deliver the dry powder to the nozzles. Dry powder fire extinguishing has a wide coverage area, is suitable for extinguishing various types of fires, and is less expensive, especially suitable for extinguishing large-area fires in the field. The nozzles can adopt a wide-angle spray design to improve fire extinguishing efficiency.

[0054] Water-based fire suppression combined with a high-pressure pump: Equipped with a large-capacity water tank and a high-pressure water pump, water is atomized and sprayed through high-pressure nozzles. Water-based fire suppression systems are environmentally friendly and low-cost, suitable for extinguishing initial fires and controlling the spread of fire. The nozzles can be prevented from clogging by impurities in the water by adding a water filtration device.

[0055] All other technical solutions in this embodiment can be the same as those in Embodiment 1. To save space, this embodiment will not be described in detail.

[0056] The above description is merely a specific embodiment of the present invention and should not be construed as limiting the scope of the invention. Therefore, any substitution of equivalent components or equivalent changes and modifications made within the scope of protection of the present invention should still fall within the scope of the present invention. Furthermore, the technical features, technical solutions, and embodiments of the present invention can be freely combined and used.
