Abstract
Description
Technical Field
[0001] This utility model relates to an aircraft used for urban security patrols, belonging to the field of aircraft technology. Background Technology
[0002] Currently, drones are the mainstream method for urban safety inspections. While they are mobile and flexible, they generally suffer from limited loiter time and high energy consumption, making it difficult to achieve continuous, all-weather aerial monitoring. Existing aerostats, such as stable loiter time, long flight duration, and low energy consumption, have inherent advantages, making them highly suitable for long-term fixed-point and large-area aerial monitoring scenarios.
[0003] While existing aerodynamic balloons can meet basic aerial inspection needs, they still have many shortcomings in actual urban security patrol applications. When landing after an inspection mission, the lack of a dedicated buffer descent structure makes it difficult to control the descent speed smoothly. Upon landing, they are prone to a rigid impact with the ground, which can easily cause damage and deformation to the airbag surface and loosening or damage to the inspection and monitoring equipment inside the basket, thus compromising the aircraft's protective capabilities. Furthermore, after landing and recovery, the bulky airbags can only be manually folded and stored by staff. This process is time-consuming and labor-intensive, making automatic airbag retraction difficult and significantly reducing the aircraft's ease of use. Utility Model Content

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example
[0016] This utility model embodiment provides an aircraft for urban security patrol.
[0017] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The system includes a mounting compartment 1, a combustion heating device 2 fixed to the upper side of the mounting compartment 1, an airbag 3 installed at the upper end of the mounting compartment 1, an inspection camera 4 installed at the lower end of the mounting compartment 1, fixing blocks 5 fixed on all four sides of the mounting compartment 1, a rack slot 6 opened in the middle of each of the four fixing blocks 5, a sliding plate 7 slidably connected to the inner wall of each rack slot 6, a support leg 8 fixed to the lower end of each sliding plate 7, a rubber base 9 fixed to the lower end of each support leg 8, and a spring 17 fixed to the upper end of each sliding plate 7. The four fixing blocks 5 are fixed to the four sides of the mounting compartment 1 on their adjacent sides, the four rack slots 6 pass through the middle of the four fixing blocks 5, the outer surfaces of the four sliding plates 7 are slidably connected to the inner walls of the four rack slots 6, and the upper ends of the four sliding plates 7 are fixed to the lower ends of the four springs 17. At the end, the upper ends of four springs 17 are fixed to the inner walls of the upper ends of four frame slots 6, the lower ends of four slide plates 7 are fixed to the upper ends of four outriggers 8, and the lower ends of four outriggers 8 are fixed to the middle of four rubber bases 9. The rubber bases 9 and springs 17 cooperate with each other to form a flexible buffer structure during the landing process of the aircraft, effectively dissipating the vertical impact force generated at the moment of landing, preventing the inspection and monitoring components carried inside the payload bay 1 from becoming loose, shifting, or even damaged due to severe vibration. At the same time, it can also reduce the possibility of airbags 3 being damaged by vibration and pulling, comprehensively reducing equipment damage caused by landing collisions, further stabilizing the overall structural stability of the aircraft, and effectively strengthening the safety protection capability of the aircraft during landing and use.
[0018] In use, this invention works as follows: the airbag 3 is raised and lowered by the combustion heating device 2, and the payload compartment 1 descends synchronously, causing the four fixed blocks 5, which are fixed around the payload compartment 1, to move downwards together. The moving fixed blocks 5 cause the four sliding plates 7, which are slidably connected to the inner wall of the frame groove 6, to descend synchronously under the support of the springs 17. The sliding plates 7 then cause the four support legs 8 connected to their bottom ends and the four rubber bases 9 at the bottom of the support legs 8 to move downwards together. When the rubber bases 9 touch the ground and remain stationary, the payload compartment 1 continues to sink downwards, causing the springs 17 installed in the frame groove 6 of the fixed blocks 5 to be compressed under the limiting support of the sliding plates 7. The elastic force generated by the deformation of the springs 17 offsets the impact force of the landing, completing the landing buffer and achieving the effect of force buffering. This effectively avoids damage to aircraft parts caused by hard impacts and improves the overall protective performance of the aircraft. Example
[0019] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 An automatic storage function has been added based on Embodiment 1; Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that the upper ends of the four slide plates 7 are provided with a connecting structure, which includes four support blocks 10. A rack 11 is fixed to one side of each of the four support blocks 10. Each rack 11 is meshed with an outer gear ring 12. A take-up roller 13 is fixed to the inner wall of each outer gear ring 12. A support frame 14 is rotatably connected to the middle of the take-up roller 13. One of the connecting ropes 15 is fixed to the middle of each of the two take-up rollers 13. Guide frames 16 are provided on the outer surfaces of the two connecting ropes 15. The lower ends of the four support blocks 10 are fixed to the middle of the upper ends of the four slide plates 7. The adjacent sides of the four slide plates 7 are fixed to the disjoint sides of the four racks 11. The adjacent sides of the four racks 11 are meshed with the four outer gear rings 12. The inner walls of the four outer gear rings 12 are fixed to the four take-up rollers 13. On the side, the inner walls of four take-up rollers 13 are rotatably connected to the outer surfaces of four support frames 14. One end of each support frame 14 is fixed to one side of four fixed blocks 5. The two ends of two connecting ropes 15 are fixed to the middle of two of the take-up rollers 13. The two connecting ropes 15 are staggered and contact the inner wall of the guide frame 16. The four ends of the guide frame 16 are fixed to the upper end of the airbag 3. The cross section of the guide frame 16 is cross-shaped. The rotating take-up rollers 13 rotate synchronously to take up the connecting ropes 15. With the guidance and limiting effect of the guide frame 16 at the top of the airbag 3, the airbag 3 is smoothly pulled and gathered. The airbag 3 is automatically gathered and stored by mechanical linkage during the landing process. There is no need for manual folding and sorting, which simplifies the recycling operation process and effectively improves the overall ease of use of the equipment.
[0020] In use, the present invention works as follows: The mounting compartment 1 descends, and after the rubber base 9 contacts the ground, the mounting compartment 1 continues to move downwards due to its own weight and inertia. At this time, the support block 10 connected to the upper end of the slide plate 7 remains stationary. The mounting compartment 1 drives the fixed block 5 to move downwards synchronously, and the moving fixed block 5 synchronously drives the support frame 14 downwards. When the support frame 14 moves downwards, it drives the take-up roller 13, which is rotatably mounted on its outer side, to descend together. The outer gear ring 12 fixed on one side of the take-up roller 13 moves downwards synchronously. The outer gear ring 12 meshes with the rack 11 fixed on the support block 10, causing the outer gear ring 12 to rotate during the downward movement, synchronously driving the take-up roller 13 to rotate while descending. Two sets of winding rollers 13 rotate synchronously, driving the two ends of the corresponding connecting ropes 15 to complete the winding operation simultaneously. Together with the guide frame 16 set on the upper end of the airbag 3, they pull and gather the airbag 3, thereby completing the automatic storage operation of the airbag 3. This achieves the effect of automatic storage without the need for manual sorting and storage, effectively simplifying the operation process and significantly improving the overall ease of use of the aircraft.
