Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a mounting device for a fire-fighting UAV. Background Technology
[0002] With the continuous development of firefighting drone technology, more and more firefighting drones are being used in fields such as firefighting, rescue, and exploration. In these applications, firefighting drones need to carry and mount various types of firefighting equipment, such as fire extinguishers and sprayers. To ensure that this firefighting equipment can be safely and stably mounted on the drone and used quickly in emergencies, a mounting device adapted to different types of firefighting equipment has been designed.
[0003] Existing mounting devices for firefighting drones typically employ fixed-size slots and mounting structures, resulting in a relatively simple design that cannot effectively adapt to firefighting equipment of different sizes and shapes. These devices mostly rely on traditional mechanical fixing methods, such as clips and hooks, to ensure equipment stability through physical connections. However, these structures often lack flexibility when dealing with different equipment models, leading to inapplicability or insecure installation, thus affecting the equipment's efficiency and safety.
[0004] Existing mounting devices suffer from a significant problem: due to their limited size and structure, they often cannot be flexibly adjusted to accommodate different types of firefighting equipment. Especially when faced with a wide variety of firefighting equipment of varying shapes and sizes, traditional devices may fail to securely mount the equipment or meet actual needs, thus impacting the efficiency of drones in firefighting operations. Therefore, there is an urgent need for a mounting device that can be adjusted to different equipment types, providing greater flexibility and stability. Summary of the Invention
[0005] To overcome the above shortcomings, this utility model provides a mounting device for fire-fighting drones, aiming to improve the problem that the mounting device has a single size and cannot be used to suspend different types of fire-fighting equipment.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a mounting device for a fire-fighting drone, comprising a drone body, wherein two parallel cantilever beams are fixedly connected to the bottom of the drone body, and the cantilever beams are provided with an elongated groove running vertically through them along their axial direction, and two sets of symmetrically arranged adjustment components are connected between the two cantilever beams.
[0007] The adjustment assembly includes a slider, a crossbar, and a clamping plate. The clamping plate is fixedly installed on the crossbar. Each end of the crossbar is connected to a slider. Guide grooves are symmetrically arranged on both sides of the slide groove. The two sliders are respectively arranged in the slide grooves of the two cantilever beams and form a sliding engagement with the guide grooves. Multiple positioning teeth are arranged at equal intervals along the axial direction on the inner side wall of the guide groove. The side wall of the slider is provided with an elastic locking block that engages with the positioning teeth. The elastic locking block interacts with the positioning teeth during the sliding of the slider to achieve initial positioning. A fastening bolt is fixedly connected to the top of the slider. A washer is fitted on the fastening bolt. A wing nut is threaded onto the fastening bolt. By tightening the wing nut, the washer is driven to fasten the slider to the cantilever beam.
[0008] As a further description of the above technical solution:
[0009] The slider is provided with a first spring, and the elastic block is located at one end of the slider and is connected to a limit plate and a guide rod that cooperates with the first spring. The elastic block penetrates the side wall of the slider.
[0010] As a further description of the above technical solution:
[0011] At least two sets of support leg assemblies are fixedly connected to the bottom of the cantilever beam. Each set of support leg assemblies includes a support rod one and a support rod two. The top end of the support rod two is fixedly connected to the cantilever beam. The support rod one is telescopically sleeved on the support rod two and fixed to the support rod two by a locking mechanism.
[0012] As a further description of the above technical solution:
[0013] The locking mechanism includes a connecting pin slidably connected to the support rod 1, a positioning pin fixedly connected to the end of the connecting pin, and a plurality of positioning holes spaced apart on the support rod 2, the positioning holes matching and fitting with the positioning pin.
[0014] As a further description of the above technical solution:
[0015] The other end of the connecting pin is hinged to a lever-type rotating buckle plate. A second spring is sleeved on the connecting pin. One end of the second spring abuts against the positioning pin, and the other end abuts against the inner wall of the support rod. The hinge point of the rotating buckle plate and the connecting pin forms a fulcrum structure. The vertical distance from the hinge point to the outer wall of the support rod is less than the length from the hinge point to the end of the rotating buckle plate.
[0016] As a further description of the above technical solution:
[0017] An anti-slip strip is fixedly connected to the side of the rotating buckle that contacts the support rod.
[0018] This utility model has the following beneficial effects:
[0019] 1. In this utility model, the elastic block is first limited in the slider by the limiting plate. Supported by the tension of the first spring, the elastic block can be stably fitted between the positioning teeth. Rotating the wing nut drives the slider and the wing nut to be fixed in the cantilever beam, which achieves the effect of adapting to different types of fire-fighting equipment. It solves the problem that the traditional mounting device has a single size and cannot be suspended according to different types of fire-fighting equipment, thus improving the convenience of the mounting device.
[0020] 2. In this utility model, the second support rod extends from the first support rod. After adjustment, the buckle plate is reset, and then the positioning pin is driven by the tension of the second spring to reset and be embedded in the positioning hole for locking. This achieves the effect of facilitating the adjustment of the landing gear height, solves the problem of easy ground contact when mounting large fire-fighting equipment, and improves the practicality of fire-fighting drones.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Reference Figures 1-3 and Figure 5 This utility model provides an embodiment of a mounting device for a firefighting drone, comprising a drone body 1. Two parallel cantilever beams 2 are fixedly connected to the bottom of the drone body 1. Each cantilever beam 2 has a vertically extending elongated groove 3 along its axial direction. Two sets of symmetrically arranged adjustment components are connected between the two cantilever beams 2. The design of the cantilever beams 2 enables the drone to stably mount various equipment or loads, ensuring the structural stability and load-bearing capacity of the mounting system.
[0030] The adjustment assembly includes a slider 4, a crossbar 5, and a clamping plate 6. The clamping plate 6 is fixedly mounted on the crossbar 5. A slider 4 is connected to each end of the crossbar 5. Guide grooves are symmetrically arranged on both sides of the slide groove 3. The two sliders 4 are respectively positioned within the slide grooves 3 of the two cantilever beams 2, forming a sliding engagement with the guide grooves. This adjustment assembly design enables the mounting device to slide and adjust between the cantilever beams, ensuring that the mounting device can flexibly adjust its position according to the needs of different tasks, thus improving the adaptability of the UAV in different application scenarios. Multiple positioning teeth 7 are arranged at equal intervals along the axial direction on the inner sidewall of the guide groove. Elastic locking blocks 9 that engage with the positioning teeth 7 are provided on the sidewall of the slider 4. The elastic locking blocks 9 interact with the positioning teeth 7 during the sliding process of the slider 4 to achieve initial positioning. The cooperation of the positioning tooth block and the elastic locking block achieves the initial positioning of the mounting device, ensuring that the slider will not shift during adjustment, enhancing the stability and reliability of the system, and avoiding position drift during adjustment. A fastening bolt 12 is fixedly connected to the top of the slider 4, with a washer 13 fitted on the bolt 12. A wing nut 14 is threaded onto the bolt 12. Tightening the wing nut 14 drives the washer 13 to securely connect the slider 4 to the cantilever beam 2. This design allows the operator to quickly and easily adjust and fix the slider's position, improving operational convenience and ensuring the stability of the mounting device during use, preventing loosening due to vibration or other external factors. A first spring 11 is installed inside the slider 4. One end of the elastic locking block 9 located inside the slider 4 is connected to a limit plate 8 and a guide rod 10 that cooperates with the first spring 11. The elastic locking block 9 penetrates the side wall of the slider 4. The first spring 11 increases the system's elasticity, allowing the slider 4 to effectively buffer external forces during adjustment, reducing the impact on the UAV, and improving the durability of the mounting device. The design of the limiting plate 8 and the guide rod 10 prevents excessive displacement of the slider, ensuring that the mounting device maintains a stable and precise position during operation.
[0031] Reference Figure 2 and Figure 4At least two sets of outrigger assemblies are fixedly connected to the bottom of the cantilever beam 2. Each set of outrigger assemblies includes a support rod 15 and a support rod 26. The top end of the support rod 26 is fixedly connected to the cantilever beam 2. The support rod 15 is telescopically sleeved on the support rod 26 and fixed to the support rod 26 by a locking mechanism. The design of the support rod 15 and the support rod 26 allows the outrigger assembly to have an adjustable length, adapt to different ground heights, provide stable support, and ensure that the fire-fighting drone has good support force and stability during operation. The locking mechanism includes a connecting pin 18 slidably connected to the support rod 15, and a positioning pin 20 fixedly connected to the end of the connecting pin 18. Multiple spaced positioning holes 17 are provided on the support rod 26, and the positioning holes 17 are matched and fitted with the positioning pins 20. Through the cooperation of connecting pin 18 and positioning pin 20, the locking mechanism can firmly fix the relative position of support rod 15 to support rod 26, ensuring the stability of the outrigger assembly during operation and preventing the support rod from becoming loose or unstable during use. The other end of connecting pin 18 is hinged to a lever-type rotating buckle plate 19. A second spring 21 is sleeved on connecting pin 18. One end of the second spring 21 abuts against the positioning pin 20, and the other end abuts against the inner wall of support rod 15. The design of the second spring provides elasticity to the locking mechanism, allowing the connection between support rod 15 and support rod 26 to withstand a certain amount of external force, preventing loosening due to excessive pressure, while improving the overall system's buffering effect and reducing the impact of external vibration on the device. The hinge point of rotating buckle plate 19 and connecting pin 18 forms a fulcrum structure. The vertical distance from the hinge point to the outer wall of support rod 15 is less than the length from the hinge point to the end of rotating buckle plate 19. This structural design provides a leverage effect, enhancing the rotational force of the buckle plate and making it easier to lock or release the support rod during operation. This improves the operational efficiency and convenience of the outrigger assembly. An anti-slip strip 22 is fixedly connected to the side of the rotating buckle plate 19 that contacts the support rod 15. The anti-slip strip design makes the contact surface between the support rod 15 and the buckle plate 19 more stable, avoiding slippage or loosening caused by insufficient friction. This improves the stability and safety of the outrigger assembly under various terrain conditions.
[0032] Working principle: When using the mounting device of this fire-fighting drone, firstly, when adjusting the spacing of the mounting device, the spacing of the clamping plates 6 is adjusted. The clamping plates 6 slide in the slide groove 3 through the slider 4 at the top of the crossbar 5. Then, the slider 4 is pre-positioned by the internal elastic locking block 9 engaging with the positioning tooth block 7. The elastic locking block 9 is limited in the slider 4 by the limiting plate 8 and supported by the tension of the first spring 11, so that the elastic locking block 9 can be stably engaged between the positioning tooth blocks 7. Then, the wing nut 14 is rotated to drive the slider 4 and the wing nut 14 to be fixed in the cantilever beam 2, so that the fire-fighting equipment is mounted on the bottom of the drone body 1 through the clamping plate 6, achieving the effect of adapting to different types of fire-fighting equipment.
[0033] When the landing gear height needs to be adjusted, the latch plate 19 is pulled to make it horizontal with the connecting pin 18. Then, the connecting pin 18 drives the positioning pin 20 to retract into the support rod 15. Then, the support rod 26 extends out from the support rod 15. After adjustment, the latch plate 19 is reset so that the latch plate 19 is perpendicular to the connecting pin 18. Then, the positioning pin 20 is driven to reset and embedded into the positioning hole 17 by the tension of the second spring 21 for locking, thus achieving the effect of facilitating the adjustment of the landing gear height.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
