Description

Technical Field

[0001] The utility model relates to the technical field of atmospheric environment monitoring, and in particular to a drone structure applied to atmospheric environment monitoring. Background Art

[0002] The structure of the drone used for atmospheric environment monitoring is mainly composed of drone platform, environmental monitoring sensors, data processing system and communication module. Its main function is to carry out real-time monitoring of parameters such as temperature, humidity, wind speed, wind direction, and particle concentration in the atmosphere by carrying various environmental monitoring sensors, and transmit the collected data to the ground data processing center for analysis and evaluation.

[0003] In existing drone environmental monitoring applications, the disassembly and assembly of environmental monitoring equipment is often a complex and time-consuming process. In traditional designs, environmental monitoring equipment is usually fixed to the drone body through multiple fasteners or screws, and disassembly and assembly require specific tools and complex operation steps. This not only increases the burden on operators, but also may lead to the risk of equipment damage or data loss during disassembly and assembly. In addition, frequent disassembly and assembly will also affect the continuity and efficiency of monitoring tasks, and cannot meet the needs of rapid response and efficient monitoring.

[0004] Moreover, during the landing process, traditional drones often have poor landing stability due to insufficient fuselage structure design and buffer mechanism, which poses a great safety hazard. Especially in complex terrain and severe weather conditions, drones are susceptible to shock and vibration during landing, which in turn affects the integrity of their fuselage structure and internal equipment. This may not only cause damage to the drone, but also pose a potential threat to the surrounding environment and personnel. For this reason, we provide a drone structure for atmospheric environment monitoring. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model provides a technical solution for the structure of an unmanned aerial vehicle used for atmospheric environment monitoring: a structure of an unmanned aerial vehicle used for atmospheric environment monitoring, which is mainly composed of a mounting plate 1, an arm 2, a driving motor 3, a propeller 4, an environmental monitor 5, a protective cover 8 and a quick disassembly structure. The mounting plate 1 serves as the main frame of the unmanned aerial vehicle. An arm 2 is fixedly installed between two mounting plates 1. A driving motor 3 is installed above the end of the arm 2. The output end of the driving motor 3 is connected to the propeller 4 to provide lift for the unmanned aerial vehicle. The environmental monitor 5 is fixedly installed on the upper surface of the upper mounting plate 1 for monitoring the atmospheric environment. The protective cover 8 is buckled on the periphery of the environmental monitor 5 to protect it from external influences; the specific implementation of the quick disassembly structure is as follows: a snap-on shell 9 is fixedly installed on the periphery of the protective cover 8, and a rectangular through groove 10 is provided at the top of the snap-on shell 9. A rectangular plug-in block 11 is fixedly connected to the upper surface of the arm 2, and a sliding groove 12 is provided at one end of the rectangular plug-in block 11. An arc-shaped limit block 17 is slidably connected in the sliding groove 12 to limit the upward movement of the protective cover 8. The arc-shaped limit block 17 is connected to the sliding groove 12 through a reset component. When the protective cover 8 is buckled in place, the arc-shaped limit block 17 is automatically snapped into the corresponding position of the snap-on shell 9 under the action of the reset component to achieve rapid fixation. When disassembly is required, it is only necessary to overcome the elastic force of the reset component and move the arc-shaped limit block 17 out of the snap-on shell 9. Through the above-mentioned quick disassembly and assembly structure, the quick connection and separation between the protective cover 8 and the machine arm 2 is achieved, which is convenient for the maintenance and replacement of the environmental monitor 5.

[0025] like Figure 1-5 As shown, the landing assembly includes a lap plate 18 fixedly mounted on the arm 2, a mounting rod 19 is vertically inserted on the lap plate 18, and the end of the mounting rod 19 is rotatably connected to a roller 20 through a bearing. When the drone needs to land or make an emergency landing, the roller 20 contacts the ground to provide a buffering effect and reduce the impact damage of the drone. A buffer structure is also connected between the lap plate 18 and the mounting rod 19 to further absorb the impact force during landing; the design of the landing assembly improves the stability and safety of the drone during landing and reduces the damage caused by the landing impact.

[0026] like Figure 1-5As shown, a placement groove 13 is provided on the inner side wall of the sliding groove 12, and a connecting rod 14 is fixedly connected between the two end walls of the placement groove 13. A spring 15 is sleeved on the periphery of the connecting rod 14, and a sliding sleeve block 16 is slidably sleeved on the periphery thereof. The opposite surfaces of the two sliding sleeve blocks 16 are fixedly connected to the two side surfaces of the arc-shaped limit block 17. When the protective cover 8 is buckled, the arc-shaped limit block 17 is squeezed by the snap-on shell 9 and moves, driving the sliding sleeve block 16 to slide on the connecting rod 14 and compress the spring 15. When the protective cover 8 is in place, the elastic force of the spring 15 causes the arc-shaped limit block 17 to automatically snap into the snap-on shell 9 to achieve fixation; the reset component realizes the automatic snapping and release of the arc-shaped limit block 17 through the elastic force of the spring 15, thereby simplifying the disassembly and assembly process.

[0027] like Figure 1-5 As shown, a limiting ring piece 21 is fixedly connected to the periphery of the mounting rod 19, and a second spring 22 is sleeved on the periphery thereof. When the roller 20 contacts the ground, the second spring 22 is compressed and generates elastic force, thereby absorbing the impact force during landing. The upper end of the second spring 22 is fixedly connected to the lower end surface of the lap plate 18, and the lower end is fixedly connected to the upper end surface of the limiting ring piece 21. The design of the buffer structure effectively reduces the impact force of the drone during landing, and improves the stability and safety of landing.

[0028] A fixing frame 6 is fixedly installed at the lower end of the mounting plate 1, and a battery 7 is installed through the fixing frame 6. The battery 7 is used to provide real-time power supply for the environmental monitor 5 and other equipment that requires power; one end of the spring 15 is fixedly connected to the end wall of the placement groove 13, and the other end is fixedly connected to one end surface of the sliding sleeve 16. This connection method ensures that the spring 15 can generate sufficient elastic force to push the sliding sleeve 16 and the arc-shaped limit block 17 to reset when compressed; the upper end of the spring 22 is fixedly connected to the lower end surface of the lap plate 18, and the lower end is fixedly connected to the upper end surface of the limit ring 21. This connection method enables the spring 22 to generate sufficient elastic force to absorb the impact force during landing when compressed.

[0029] The working principle of the utility model is as follows: when the protective cover 8 needs to be installed on the environmental monitor 5, first align the snap-on shell 9 on the protective cover 8 with the rectangular plug-in block 11 at the upper end of the machine arm 2 and push it downward. During the pushing process, the snap-on shell 9 is sleeved on the rectangular plug-in block 11 through the rectangular through slot 10, and at the same time, the arc-shaped limit block 17 slides in the sliding groove 12 and compresses the reset component, i.e., the spring 15. When the snap-on shell 9 is completely sleeved on the rectangular plug-in block 11, the arc-shaped limit block 17 automatically pops out under the elastic force of the spring 15 and snaps into the corresponding position of the snap-on shell 9 to fix the protective cover 8.

[0030] When the protective cover 8 needs to be removed, it is only necessary to gently press the arc-shaped limit block 17 to make it overcome the elastic force of the spring 15 and retract into the sliding groove 12. Then, the protective cover 8 is lifted upward to separate the snap-on shell 9 from the rectangular plug-in block 11, and the removal is completed.

[0031] When the drone needs to land, the roller 20 first contacts the ground. Since the roller 20 is rotatably connected to the mounting rod 19 through a bearing, it can flexibly adapt to the unevenness of the ground. At the same time, when the mounting rod 19 is impacted by the ground, it will compress the spring 22 in the buffer structure. The elastic force of the spring 22 can absorb part of the impact force and slow down the descending speed of the mounting rod 19, thereby protecting the drone body from damage; the limiting ring 21 serves as a limiting component of the mounting rod 19, and together with the spring 22, it forms a buffer structure;

[0032] When the mounting rod 19 is impacted, the limiting ring 21 will compress the spring 22, causing it to deform and store energy. As the impact force gradually decreases, the spring 22 will release the stored energy, pushing the mounting rod 19 and the roller 20 to reset, thereby completing the buffering process.

[0033] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
