Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) firefighting, and more specifically, to a UAV bazooka launching device. Background Art

[0002] Drone firefighting refers to the use of drone technology for fire monitoring, investigation, rescue, and extinguishing. Compared to traditional manual firefighting and rescue, drone firefighting is more efficient, safer, and faster. Drones can monitor and investigate fires using a variety of sensors, such as infrared cameras, high-definition video cameras, and smoke detectors, providing real-time information on the fire situation. They can also be equipped with various spraying equipment, such as water mist sprayers and dry powder fire extinguishers, to directly extinguish fires. Furthermore, drone firefighting allows for rapid response and rescue in hard-to-reach locations, such as high-rise buildings and mountainous areas. Consequently, drone firefighting is widely used in various settings, including cities, forests, and oceans, and is gaining increasing attention.

[0003] Currently, fire extinguishing grenade launchers on drones typically use vertical, free-fall, or horizontal methods to launch fire extinguishing grenade launchers. When facing fires in high-rise buildings or at specific angles, traditional vertical or horizontal launch methods may be limited, making them inaccurate and affecting firefighting effectiveness.

[0004] For example, a drone fire-fighting launcher with patent application number CN202322964621.9 can only extinguish horizontal fire sources during use. When facing a large fire on a high floor, it cannot be launched at the same level. The device cannot accurately hit the target, thereby affecting the fire-fighting effect. Alternatively, electric telescopic rods are used at both ends of the launcher to achieve angle adjustment. Electric telescopic rods are used at the front and back, which will cause the angle adjustment components of the device to be too heavy and costly. Utility Model Content

[0020] Figure 1 The present invention shows a UAV rocket launcher device, comprising: a mounting plate 1 connected to the UAV, a launch tube rack 2 provided on the mounting plate 1 for mounting multiple fire extinguishing bombs, a connecting rod I 4 being hinged at one end of the top of the launch tube rack 2, and a connecting rod II 5 being hinged at the other end;

[0021] The free end of the connecting rod I4 is fixedly connected to the mounting plate 1, and the free end of the connecting rod II5 is connected to the mounting plate 1 through a connecting seat 6, and the connecting rod II5 is hinged to the connecting seat 6; a sliding rod 7 with a T-shaped structure is provided on the connecting seat 6, and a T-shaped slot 8 for the sliding rod 7 to extend into is provided inside the mounting plate 1; a driving motor 9 is provided on the connecting seat 6, and a groove 11 is provided at the bottom of the mounting plate 1 at a position cooperating with the driving motor 9, and a rack 12 is provided in the groove 11 along the length direction, and a gear 10 meshing with the rack 12 is provided at the output end of the driving motor 9; wherein, the length of the connecting rod II5 is greater than the length of the connecting rod I4.

[0022] Working principle:

[0023] During the operation of the device, the drone is connected to the top of the mounting plate 1, and then multiple fire extinguishing bombs 16 are installed on the launch tube bracket 2. A connecting rod Ⅰ4 is hinged at one end of the top of the rear end of the launch tube bracket 2, and the other end of the connecting rod Ⅰ4 is fixedly connected to the mounting plate 1 to ensure that the rear end of the launch tube bracket 2 can rotate in space. When the angle of the launch tube bracket 2 needs to be adjusted, the drive motor 9 on the connecting seat 6 is started. The output shaft of drive motor 9 rotates gear 10. Gear 10 meshes with rack 12, which is fixedly mounted within groove 11 at the bottom of mounting plate 1. Driven by drive motor 9, gear 10 moves linearly along rack 12. This linear motion is transmitted to connecting rod II 5 via connector 6. Because connecting rod II 5 is hingedly connected to both the launch tube mount 2 and connector 6 at both ends, the movement of gear 10 changes the angle between connecting rod II 5 and mounting plate 1, thereby causing the launch tube mount 2 to adjust its angle around the hinge point of connecting rod I 4. Since slide bar 7 is connected to connector 6, it also moves with it. The T-shaped slide bar 7 moves back and forth within the T-shaped slot 8 (the T-shaped slide bar 7 is mounted near the center of connector 6 to ensure structural stability and prevent center of gravity shift). This ensures close spatial contact between gear 10 and rack 12, preventing them from falling. Since the length of the connecting rod II 5 is greater than that of the connecting rod I 4, this change can significantly affect the tilt angle of the rack. When the slide bar 7 moves to the predetermined position, the drive motor 9 stops working, thereby locking the angle of the launch tube rack 2.

[0024] The above technical solution also includes: a fixed plate 13 disposed at the bottom of the mounting plate 1 for closing the groove 11; wherein, the surface of the fixed plate 13 is provided with a waist-shaped hole for the output shaft of the drive motor 9 to extend along the direction of the spatial layout of the rack 12, and the size of the gear 10 is larger than the size of the waist-shaped hole. Using this technical solution, the main function of the fixed plate 13 is to close the groove 11 at the bottom of the mounting plate 1, protecting the internal rack 12 and other potentially exposed mechanical components from interference and damage from the external environment, thereby extending the service life of the equipment. The waist-shaped hole allows the motor output shaft to have a certain range of movement during the driving process to match the length of the rack 12. At the same time, the length of the waist-shaped hole is shorter than the length of the rack 12, which also prevents the gear 10 from disengaging from the rack 12.

[0025] In the above technical solution, the ejection port at the end of the launch tube 3 is hinged with a cover plate 14. With this technical solution, the cover plate 14 can ensure that when the internal pressure of the launch tube 3 is too high, the cover plate 14 is blown open by the pressurized gas, reducing the impact of the fire extinguishing bomb 16 on the flight posture of the drone when it is launched.

[0026] In the above technical solution, the cover 14 is mounted at the ejection port via a damping hinge 15. This ensures that when the internal pressure of the launch tube 3 is initially low, the cover 14 is restrained by the greater resistance of the damping hinge 15 and does not fully open. As the internal pressure of the launch tube 3 gradually increases, the cover 14 gradually opens. This ensures that the fire extinguishing bomb 16 has a high speed and range when launched, while also minimizing the impact of the launch on the drone's flight posture.

[0027] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
