Description
Technical Field
[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) instrument fixing, specifically relating to a fixing device for UAV-carried analytical and testing instruments. Background Technology
[0002] The design and application of fixed devices for carrying analytical and testing instruments on UAVs is a key area, especially when UAVs are used for tasks such as scientific research, environmental monitoring, and industrial inspection. Ensuring that the instruments are carried and operated stably, safely, and accurately is of paramount importance.
[0003] Traditional drone instrument mounting devices mostly use integrated brackets with bolts or other fixing structures to fix the testing instruments to the drone. However, in actual use, the testing instruments installed on the drone often need to be changed frequently due to the different tasks the drone needs to perform. The mounting brackets of the fixed structure cannot meet the needs of quick assembly and disassembly, and the general quick assembly and disassembly structure has limited effect on fixing the testing instruments. In the event of severe weather, the testing instruments are prone to falling off the drone.
[0004] Therefore, in order to address the problems of traditional UAV instrument fixing devices being inconvenient to assemble and having poor instrument fixing effects, a fixing device for UAV-carried analytical testing instruments has been developed. By adding screw fixing structures and quick assembly structures to the UAV instrument fixing device, the convenience of using the UAV instrument fixing device and the firmness of fixing the testing instruments can be effectively improved.

Detailed Implementation
[0025] The design and application of mounting systems for UAVs carrying analytical testing instruments is a critical area, especially when UAVs are used for scientific research, environmental monitoring, and industrial inspection. Ensuring the stable, safe, and accurate carrying and operation of the instruments is paramount. Below are some common design considerations and solutions:
[0026] 1. Basic requirements for load fixing devices
[0027] Stability: The instrument mounting system must ensure that the instrument does not shake, shift, or detach during flight. Shock absorption and vibration isolation technologies are typically used to reduce the impact of drone vibrations on the instrument. Lightweight: The mounting system itself needs to be as lightweight as possible to minimize its impact on drone flight performance, while being robust enough to prevent damage from external impacts. Ease of Operation: Installation and disassembly of the instrument need to be simple to adapt to different mission and environmental requirements. Aerodynamic Design: The shape of the mounting system should be as streamlined as possible to reduce negative impacts on drone flight stability and energy consumption.
[0028] 2. Common types of fixing devices
[0029] Bracket-type mounting devices: These use metal or composite materials (such as aluminum alloy or carbon fiber) to support and secure the instrument. The brackets can be designed to be adjustable to accommodate instruments of different sizes and types. Flexible mounting devices: These use rubber pads, springs, or other elastic materials to reduce vibration and ensure instrument stability during flight. These devices are commonly used for shock absorption and vibration isolation, especially for high-precision measuring instruments. Magnetic mounting devices: These use strong suction cups or magnetic fasteners to secure the instrument. They are suitable for flat surfaces or scenarios where long-term fixation is not required. Modular design: Modular mounting systems allow for flexible configuration of different types of instruments as needed. For example, some mounting devices can be quickly replaced to adapt to different mission requirements.
[0030] 3. Design Considerations
[0031] Load balancing and center of gravity control: The weight distribution of the instrument and the mounting system must be considered during the design to ensure a balanced center of gravity, thus avoiding any impact on the UAV's flight stability. Wind resistance and air resistance: The mounting system must take into account the effects of wind speed, flight altitude, and other factors. Increased external wind resistance may lead to increased power consumption during flight, so it is necessary to minimize wind resistance, especially when flying in high wind conditions. Protection: If the instrument is sensitive to the environment (e.g., weather conditions, vibration), a mounting system with a protective shield can be designed to prevent external factors from affecting the instrument.
[0032] 4. Common UAV-borne instruments
[0033] The analytical and testing instruments typically carried by drones include: gas analyzers (for air quality monitoring and pollutant detection), spectrometers (for material composition analysis, such as laser Raman spectrometers and ultraviolet-visible spectrometers), thermal imagers (for temperature analysis and monitoring, widely used in agriculture, energy, and construction), meteorological sensors (for real-time monitoring of meteorological parameters such as wind speed, humidity, and temperature), and multispectral / hyperspectral imagers (for remote sensing, environmental monitoring, and other fields). These instruments require high precision, so the design of the fixed devices must ensure that they are not affected by any factors during flight and maintain stable operation.
[0034] 5. Practical Application Cases
[0035] Agricultural monitoring: Common instruments carried by agricultural drones include multispectral cameras and infrared thermal imagers, used for crop health assessment and pest detection in farmland. Fixed mounting systems need to ensure these high-precision instruments are unaffected by vibration or external factors, ensuring the accuracy of data acquisition. Environmental monitoring: Sensors used for monitoring air quality, soil pollution, and water quality also need to be securely fixed, especially when dealing with harsh weather or complex terrain, where the reliability of the mounting system is paramount. Military reconnaissance: In military applications, the optical, infrared sensors, radar, and other equipment carried by drones require high-precision mounting systems to ensure their stability and accurate measurements during flight.
[0036] Summarize
[0037] The mounting system for UAVs carrying analytical testing instruments needs to achieve a balance in terms of stability, lightweight design, vibration damping, and aerodynamics to ensure the safety, accuracy, and efficiency of the instruments during flight. The design must consider not only the characteristics of the payload itself but also multiple factors such as the flight environment and mission requirements.
[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0039] Please see Figures 1-7 This utility model provides an embodiment of a fixing device for a drone carrying an analytical testing instrument, including a drone body 1, a testing instrument body 4, and a buffer landing gear 2, as well as an instrument fixing frame 3, a first magnet 6, a spring damper 12, and a second magnet 14. A first groove 7 is formed at the lower center of the drone body 1, and the first magnet 6 is fixedly connected to the upper inner wall of the first groove 7. A rubber pad 5 is fixedly connected to the lower end of the first magnet 6. Four sets of buckles are evenly distributed around the center of the inner wall of the first groove 7. 8. A second groove 13 is provided at the upper end of the splicing block 9. A second magnet 14 is installed in the second groove 13. Four sets of slots 10 are equidistantly distributed around the splicing block 9 on the outer wall. The slots 10 are adapted to the buckles 8. The outer wall of the splicing block 9 is in contact with the inner wall of the first groove 7. The first magnet 6 is adapted to the second magnet 14. The left and right ends of the instrument fixing frame 3 are provided with threaded grooves 18. Fastening bolts 19 are installed in the threaded grooves 18. The lower end of the UAV body 1 is equipped with a buffer landing gear 2.
[0040] The first magnet 6 and the second magnet 14 attract each other, and the slot 10 and the buckle 8 are matched to facilitate the user to quickly install the splicing block 9 and the instrument mounting bracket 3 installed on it into the first groove 7 under the drone body 1, thereby realizing the quick assembly and disassembly between the detection instrument body 4 and the drone body 1. The rubber pad 5 can reduce the collision between the first magnet 6 and the second magnet 14, thereby improving their service life. The two sets of fastening bolts 19 distributed on the left and right sides can be used to reinforce the left and right ends of the detection instrument body 4 that is limited and installed on the instrument mounting bracket 3, so as to improve the firmness of the detection instrument body 4 installed on the instrument mounting bracket 3.
[0041] Please see Figures 6-7 In this embodiment, the instrument mounting bracket 3 is fixed to the lower end of the movable block 16. The outer wall of the movable block 16 is in contact with the inner wall of the buffer cylinder 11. During use, the movable block 16 can slide up and down along the inner wall of the buffer cylinder 11, thereby cooperating with the spring damper 12 to buffer and reduce shock on the movable block 16. The instrument mounting bracket 3 is equipped with the detection instrument body 4. The detection instrument body 4 is compatible with the instrument mounting bracket 3. During use, the instrument mounting bracket 3 can be used to initially limit the installation of the detection instrument body 4, so that the user can replace different types of detection instrument bodies 4. The fastening bolts 19 are symmetrically distributed on the left and right. The ends of the fastening bolts 19 that are close to each other are in contact with the left and right ends of the detection instrument body 4. During use, the left and right ends of the detection instrument body 4 can be auxiliaryly fixed by the symmetrically distributed fastening bolts 19 to improve the firmness and stability of its installation in the instrument mounting bracket 3.
[0042] Please see Figures 3-6 In this embodiment, a buffer cylinder 11 is fixedly connected to the lower end of the splicing block 9. Limiting grooves 15 are opened through the front and rear ends of the buffer cylinder 11. In use, the limiting grooves 15 can assist the limiting block 17 in limiting, so as to improve the stability of the movable block 16 when it is moving up and down. Spring dampers 12 are fixedly connected to the four corner edges of the upper inner wall of the buffer cylinder 11. The movable block 16 is fixedly connected to the lower end of the spring damper 12. In use, the spring damper 12 can dampen and reduce the vibration of the instrument fixing frame 3 and the detection instrument body 4 on the movable block 16. Limiting blocks 17 are fixedly connected to the front and rear ends of the movable block 16. The outer wall of the limiting block 17 fits against the inner wall of the limiting groove 15. In use, the limiting block 17 and the limiting groove 15 can help improve the stability of the movable block 16 when it is buffering and reducing vibration.
[0043] Before use, first install the required testing instrument body 4 onto the instrument mounting bracket 3, and then tighten the fastening bolts 19 to clamp and fix the left and right ends of the testing instrument body 4 in a threaded manner.
[0044] Next, the splicing block 9 is installed into the first groove 7, and the slot 10 and the second magnet 14 are adapted to the buckle 8 and the first magnet 6 in the first groove 7, and then the instrument fixing frame 3 with the detection instrument body 4 is installed onto the drone body 1.
[0045] In use, the spring damper 12 effectively buffers the flight vibrations received by the instrument body 4 on the movable block 16, while the limiting block 17, in conjunction with the limiting groove 15, assists the spring damper 12 in driving the movable block 16 to perform buffering lifting and lowering, thereby improving the buffering effect of the spring damper 12 on the instrument body 4.
[0046] Through the above steps, the first magnet 6 and the second magnet 14 attract each other, and the slot 10 and buckle 8 are matched, so that the user can quickly install the splicing block 9 and the instrument fixing frame 3 installed on it into the first groove 7 under the drone body 1. This enables quick assembly and disassembly between the detection instrument body 4 and the drone body 1. The two sets of fastening bolts 19 distributed on the left and right sides can be used to reinforce the left and right ends of the detection instrument body 4 that are fixed on the instrument fixing frame 3, so as to improve the firmness of the detection instrument body 4 installed on the instrument fixing frame 3. This solves the problem that traditional drone instrument fixing devices are inconvenient to assemble and have poor instrument fixing effect.
[0047] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
