Description

Technical Field

[0001] This utility model relates to the field of protective netting technology, specifically an adjustable protective netting frame for drone training. Background Technology

[0002] The fixed-angle design cannot be adjusted according to different sites, flight requirements, or training conditions. In different training environments or during the flight of different types of drones, the angle of the net frame cannot be adjusted to cope with changes in flight trajectory and altitude, resulting in an inability to provide optimal protection or blocking effect. An existing construction safety net (publication number: CN214697027U) exhibits at least the following defects in use:

[0003] 1. A fixed-angle design cannot be adjusted to suit different venues, flight requirements, or training conditions. In different training environments or during the flight of different types of drones, the angle of the protective net cannot be adjusted to cope with changes in flight trajectory and altitude, resulting in an inability to provide optimal protection or blocking effect. Therefore, an adjustable protective net for drone training is needed.

[0004] 2. The lack of modular design means the protective netting structure is fixed and cannot be quickly adjusted to meet different site requirements. It cannot flexibly adapt to training sites of varying sizes or shapes, leading to inconvenience. Therefore, a modular protective netting for drone training is needed.

[0005] 3. Protective netting without windproof design is easily affected by strong winds, causing it to tilt, sway, or even collapse. This instability can pose safety hazards during training, especially outdoors or in windy conditions, failing to effectively protect trainees and equipment. Therefore, a windproof protective netting for drone training is needed. Utility Model Content

[0006] The main objective of this invention is to provide an adjustable protective net frame for drone training, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An adjustable protective net frame for drone training includes a main protective net, a main rotating shaft, and a main fixing ring. The main protective net has main rotating shafts installed on both sides, and a main fixing ring is installed on the outside of the main rotating shafts. A hinge is installed on the side of the main fixing ring, and a secondary protective net is installed at the other end of the hinge. A secondary rotating shaft is installed on one side of the secondary protective net, and a secondary fixing ring is installed on the outside of the secondary rotating shaft. A hinge is installed on the side of the secondary fixing ring. The main protective net has a connector, and a diagonal support rod is installed on the connector. A fixed base is installed at the bottom of the main rotating shaft and the secondary rotating shaft.

[0009] Preferably, the secondary protective net can rotate 90 degrees.

[0010] Preferably, the inclined support rod has an inclination angle of 30 degrees and is a detachable structure.

[0025] Example

[0026] Please see Figure 1-3 The present invention provides the following technical solution:

[0027] An adjustable protective net frame for drone training includes a main protective net 1, a main rotating shaft 2, and a main fixing ring 3. The main rotating shaft 2 is installed on both sides of the main protective net 1, and the main fixing ring 3 is installed on the outside of the main rotating shaft 2. A hinge 10 is installed on the side of the main fixing ring 3, and a secondary protective net 7 is installed at the other end of the hinge 10. A secondary rotating shaft 8 is installed on one side of the secondary protective net 7, and a secondary fixing ring 9 is installed on the outside of the secondary rotating shaft 8. A hinge 10 is installed on the side of the secondary fixing ring 9. The main protective net 1 is provided with a connector 4, and a diagonal support rod 5 is installed on the connector 4. A fixed base 6 is installed at the bottom of the main rotating shaft 2 and the secondary rotating shaft 8.

[0028] Specifically: the secondary protective net 7 can rotate 90 degrees.

[0029] Specifically: the inclined angle of the inclined support rod 5 is 30 degrees, and the inclined support rod 5 is a detachable structure.

[0030] Specifically, the main fixing ring 3 and the secondary fixing ring 9 are detachable structures.

[0031] Specifically: the fixed base 6 is fixed by fixing bolts.

[0032] Specifically: A secondary protective net 7 can be installed on the other side of the secondary fixing ring 9.

[0033] In this embodiment, main rotating shafts 2 are installed on both sides of the main protective net 1, main fixing rings 3 are installed on the outside of the main rotating shafts 2, hinges 10 are installed on the side of the main fixing rings 3, and secondary protective net 7 is installed on the other end of the hinges 10. The secondary protective net 7 can rotate 90 degrees.

[0034] The shapes of drone training grounds are often not completely standard; some may be open, while others are confined spaces (such as indoor or fenced areas). Traditional fixed-angle protective netting is often difficult to adapt to these irregular ground configurations.

[0035] The adjustable protective netting can be flexibly adjusted to suit the actual shape of the training area. For example, if the training area is narrow or has obstacles, the secondary protective netting 7 can rotate 90 degrees to ensure that every corner of the flight area is effectively protected. After adjusting the angle, the protective netting can adapt to different site layouts without leaving any exposed areas.

[0036] In a large, open area, adjusting the angle of the netting can provide coverage in multiple directions, thereby reducing the risk of drones flying out of the protected area.

[0037] During training, drones typically perform a variety of flight missions, including straight-line flight, circular flight, dives, and hovering. These flight paths cause the drone to move in different directions and at different altitudes.

[0038] With its adjustable design, the protective mesh can track the drone's flight path in real time. For example, when the drone is flying at low altitude, the mesh angle can be adjusted to be closer to the ground, providing more effective protection. When flying at high altitude or over long distances, the mesh angle can adapt to higher flight paths, ensuring adequate protection throughout the entire flight.

[0039] When the flight path of a drone changes, a traditional fixed-angle protective net may lose its effective coverage, while an adjustable design can adjust the angle of the net frame in time to prevent the drone from colliding with the protective net or leaving the protection range.

[0040] During flight, drones adjust their altitude according to different mission requirements. For example, they may fly at a lower altitude when performing obstacle avoidance, while they may fly at a higher altitude when performing long-distance missions. Different flight altitudes require different angles of protective netting to effectively cover the entire flight space.

[0041] The adjustable angle of the secondary protective net 7 allows the protective net frame to automatically adjust its angle according to the flight altitude, ensuring that the net frame angle is low enough during low-altitude flight to prevent drones from colliding with it. During high-altitude flight, the protective net frame can be adjusted to a higher position to ensure it can still effectively intercept flying drones.

[0042] In actual training, drones often need to fly across multiple altitude levels, especially when performing complex tasks. The adjustable design ensures that the protective netting always covers the drone at different flight altitudes, providing comprehensive safety.

[0043] During training, especially outdoors, changes in wind speed and airflow can affect the flight stability of drones. At high wind speeds, drones may veer off course or become uncontrollable. In such cases, the protective netting needs to be adjusted to a favorable angle to prevent the drone from leaving the training area.

[0044] Different lighting conditions (such as strong daylight or shadows) can affect the drone's flight path and the trainee's performance. An adjustable protective mesh frame can be angled to prevent strong reflected light from affecting the training process while ensuring effective protection of the flight area.

[0045] The adjustable angle of the protective netting ensures it can adapt to changes in wind direction and airflow under varying climatic conditions. For example, in headwinds, adjusting the angle of the netting helps reduce wind interference and maintain the stability of the training environment.

[0046] Drone training missions are diverse, such as aerial photography, agricultural spraying, and search and rescue, each with different flight requirements. The adjustable angle of the protective mesh frame allows for precise protection design based on mission requirements, ensuring uninterrupted training.

[0047] With its adjustable design, the main protective net 1 and the secondary protective net 7 can adjust their angles according to different training needs (the secondary protective net 7 can rotate 90 degrees), effectively coping with various changes such as different site shapes, flight trajectories, and flight altitudes. This flexibility and adaptability not only ensures optimal protection but also improves the safety, efficiency, and operability of training. Whether it's a complex flight mission or changing environmental conditions, the adjustable design provides more comprehensive and detailed protection for UAV training.

[0048] In this embodiment, the inclined support rod 5 is a detachable structure, and the main fixing ring 3 and the secondary fixing ring 9 are detachable structures.

[0049] Modular design allows the protective netting to be flexibly adjusted to suit the size, shape, and layout of different training venues. By disassembling or adding modules, the netting can quickly adapt to various venue needs, whether it's a small indoor space or a large, open outdoor training area. Fixed structures without modular design cannot be quickly adjusted to changes in venue size, limiting the flexibility and adaptability of the netting. Modular design, on the other hand, allows for easy structural adjustments based on actual needs, avoiding wasted space and improving efficiency.

[0050] The detachable diagonal support rod 5, main fixing ring 3, and secondary fixing ring 9 allow the entire protective net frame to be quickly disassembled and reassembled. For training environments requiring frequent movement and adjustments, the modular design significantly reduces the complexity and time spent on disassembly and assembly. Traditional fixed protective net frames are typically bulky and inconvenient to disassemble and assemble, especially when rapid deployment or site reconfiguration is needed, leading to wasted time and increased labor intensity for personnel. The modular design allows for easy disassembly and rapid reassembly, making the training process more efficient.

[0051] Modular design allows for the addition or reduction of components in the protective mesh frame as needed to meet varying training requirements. For example, if the protection area of ​​the training zone needs to be expanded, an additional protective mesh can be added, or the length of the existing mesh frame can be extended. This scalability enables the protective mesh frame to meet training needs of different scales. Traditional non-modular structures cannot be expanded or reduced as needed during training, limiting their application in training scenarios of varying scales and complexities. Modular design offers greater flexibility and customization, allowing adjustments to be made based on specific training tasks and site size.

[0052] Modular design allows for individual replacement of damaged or worn components, reducing overall equipment maintenance costs. For example, if a support rod or fixing ring is damaged, the user only needs to replace that component, rather than the entire protective mesh frame. Without modular design, the entire protective mesh frame might require extensive disassembly and replacement, increasing maintenance costs and time. Modular design, on the other hand, reduces the complexity of repairs and saves maintenance time and resources.

[0053] Modular design allows for customization to suit different training missions. For example, some missions may require a higher level of protection, while others may have lower requirements for the protective netting. By adjusting the configuration of the modules, the protective netting can be adapted to various flight missions and training needs. Fixed structures cannot be quickly adjusted to meet different training mission requirements, resulting in wasted resources or insufficient protection. Modular design provides appropriate protection for each mission, improving training effectiveness and safety.

[0054] Modular protective netting can be precisely laid out in training fields according to the size and shape of the space. By adjusting the position and number of each module, the utilization rate of the space can be maximized. Protective netting without a modular design may not be able to fully utilize every inch of space in a training field, especially in fields with complex shapes, where the layout may not be flexible enough. Modular design allows each field to be rationally laid out according to its characteristics, making full use of space.

[0055] The modular design allows for rapid deployment in various training environments, adapting to diverse weather and site conditions. If temporary adjustments to the training ground are needed (such as changes to indoor layout or relocation to the outdoors), it can be quickly disassembled and reassembled, saving time and ensuring rapid deployment. Traditional fixed-design protective netting can take a considerable amount of time to adjust and deploy, especially in different environments. This flexible modular design makes deployment much faster, reducing site preparation time.

[0056] Modular design allows users to select appropriate modules for configuration based on their budget and needs, thereby controlling costs. Adjustments and additions to components as needed avoid over-design and unnecessary expenses. Fixed-structure protective netting requires the purchase and installation of all components at once, potentially leading to resource waste and unnecessary costs. Modular design allows for flexible configuration according to training needs, reducing the risk of over-investment and improving cost-effectiveness.

[0057] Modular protective netting for drone training offers exceptional flexibility and adaptability through its detachable and flexibly configurable design. It can quickly adapt to the needs of different sites, tasks, and environments, while also improving training efficiency, saving costs, and reducing maintenance and operational complexity. This modular design allows the protective netting to provide customized protection while ensuring efficient and safe use under various conditions.

[0058] In this embodiment, the main protective net 1 is provided with a connector 4, and the connector 4 is equipped with a diagonal support rod 5, the diagonal support rod 5 having an inclination angle of 30 degrees.

[0059] By designing inclined support rods 5 with a 30-degree tilt angle, this design increases the support surface of the protective mesh frame, helping it maintain stability in windy conditions. The angle and design of the inclined support rods 5 help disperse wind pressure, reducing the direct impact of wind on the mesh frame. Protective mesh frames without windproof design are prone to tilting or swaying in windy conditions, and may even collapse. The inclined support rods 5 effectively disperse the impact of wind, increasing the wind resistance of the mesh frame and avoiding the risk of accidental collapse in windy environments.

[0060] The windproof design reduces wind interference with the protective netting, ensuring its stability and effectively protecting the safety of personnel and equipment within the training area. Especially in strong winds, the stability of the netting is crucial, preventing drones from flying out of the training area or the netting from collapsing. Without this windproof design, strong winds could cause the netting to tilt or collapse, resulting in injury to trainees or damage to equipment. The windproof design effectively prevents this, ensuring the safety of drone training.

[0061] The windproof design ensures the stability of the protective netting under adverse weather conditions, allowing training to proceed smoothly in various environments. This stability reduces training interruptions, ensuring trainees can focus on flight training without being disrupted by external environmental instability. If the protective netting is susceptible to wind, training may be forced to pause in strong winds, impacting trainees' learning progress. The windproof design allows trainees to train in a more stable environment, thereby improving training efficiency and quality.

[0062] The wind-resistant design allows the protective netting to adapt to various outdoor environments and climate conditions. Whether in windy mountainous areas or open grasslands, the protective netting remains stable, avoiding the need for frequent adjustments or disassembly due to weather changes. Protective netting without a wind-resistant design cannot withstand strong winds and may require additional windproofing measures or temporary adjustments, increasing the complexity and uncertainty of training site management. The wind-resistant design ensures stable use of the protective netting under various climatic conditions, enhancing its adaptability.

[0063] With its diagonal support rods and wind-resistant design, the protective mesh frame can withstand the direct impact of wind, reducing wind damage to the structure and extending the equipment's lifespan. It also reduces component wear and structural deformation caused by wind, thereby lowering the frequency of maintenance and component replacement. Protective mesh frames without wind-resistant design may be damaged in strong winds, leading to frequent component replacement or maintenance, increasing costs. The wind-resistant design improves the equipment's durability and reduces the need for repair and replacement.

[0064] A stable protective netting structure ensures the continuous use of the training ground under various weather conditions, preventing equipment malfunction or training interruptions due to excessive wind. This stability allows the ground to be used in most weather conditions, maximizing its utilization. Strong winds may temporarily render the ground unusable, impacting its efficiency. Through its windproof design, the training ground can be fully utilized in various environments, reducing the impact of weather on its utilization rate.

[0065] Stable protective netting reduces wind-induced collapses or accidents, lowering legal and economic risks associated with equipment damage or personal injury. For training institutions, ensuring equipment stability and safety is crucial for minimizing liability risks. Protective netting without wind-resistant design can lead to collapses, increasing the institution's liability and risk. Wind-resistant design effectively reduces such risks by enhancing the stability of the netting.

[0066] A stable protective net makes trainees feel safer during training, allowing them to focus more on improving their flight skills. The net remains stable even in strong winds, preventing unnecessary interference from the external environment. A protective net without wind protection can make trainees feel unsafe, especially in strong winds, increasing their anxiety. Windproof design enhances trainees' sense of security, thereby improving the training experience and effectiveness.

[0067] The windproof protective net frame for drone training, with its diagonal support rods and wind-resistant design, ensures stability even in strong winds, effectively improving the safety, adaptability, and efficiency of the training site. It guarantees smooth training in various weather conditions, reduces safety hazards, extends equipment lifespan, and enhances the training experience for participants.
