[0002] Firefighting drones are a high-altitude firefighting tool that can play an important role in firefighting. They can help firefighters extinguish fires more quickly and accurately, reduce the damage caused by fires, and also improve the safety of firefighters.

[0003] Existing firefighting drones use fire extinguishing bombs to put out fires. The launching gun barrel on the drone will drop the fire extinguishing bombs to the designated area for precise fire extinguishing. However, drones are usually equipped with multiple groups of launching gun barrels for continuous launch of fire extinguishing bombs. Since multiple launching groups of gun barrels are usually fixed together, the recoil of the launching gun barrel firing the fire extinguishing bomb will affect the firing accuracy of the next group of launching gun barrels, thereby reducing the fire extinguishing effect of the drone during continuous launch. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 , an embodiment provided by the utility model:

[0025] A fire-fighting drone with precise delivery, comprising:

[0026] The main body includes a drone body 1, on the surface of which a camera 11 is fixedly mounted;

[0027] The bomb throwing mechanism includes a mounting block 2, which is fixedly mounted on the bottom of the UAV body 1. A launching frame 21 is fixedly connected to the lower surface of the mounting block 2, a first spring 22 is fixedly connected to the surface of the launching frame 21, a fixing ring 23 is fixedly connected to the surface of the first spring 22, a launching gun barrel 24 is fixedly connected to the surface of the fixing ring 23, and the launching gun barrel 24 is slidably connected to the surface of the launching frame 21. The bomb throwing mechanism performs the task of throwing fire extinguishing bombs through multiple groups of launching gun barrels 24. By separating the multiple groups of launching gun barrels 24 and then using the recoil of a single group of launching gun barrels 24, the impact of the launching gun barrel 24 firing fire extinguishing bombs on other launching gun barrels 24 is greatly reduced, thereby ensuring the accuracy of the continuous firing of fire extinguishing bombs by the launching gun barrel 24 and ensuring the fire extinguishing effect of the UAV.

[0028] Furthermore, a mounting mechanism is provided at the bottom of the drone body 1, and the mounting mechanism includes a fixed block 3, the fixed block 3 is fixedly connected to the lower surface of the drone body 1, a second spring 31 is fixedly connected to the surface of the fixed block 3, a connecting plate 32 is fixedly connected to the surface of the second spring 31, a limiting rod 33 is fixedly connected to the surface of the connecting plate 32, and the limiting rod 33 is slidably connected to the surface of the fixed block 3. The mounting block 2 is fixedly mounted on the bottom of the drone body 1 through the fixed block 3. The mounting mechanism can quickly mount the launching barrel 24 on the bottom of the drone body 1, thereby improving the replacement efficiency of the launching barrel 24, and further improving the efficiency of the launching barrel 24 in throwing fire extinguishing bombs.

[0029] Furthermore, the drone body 1 supports the launch frame 21 through the mounting block 2, and multiple groups of launch barrels 24 are provided. The launch frame 21 is composed of multiple groups of guide tubes. The multiple groups of launch barrels 24 slide on the guide tubes of the launch frame 21. The launch barrels 24 are always restricted on the surface of the launch frame 21. When launching fire extinguishing bombs, the launch barrels 24 will slide on the guide tubes of the launch frame 21 one after another, so as to avoid affecting the launch positions of other launch barrels 24.

[0030] Furthermore, the diameter of the fixing ring 23 is the same as the diameter of the guide tube of the launching frame 21, and the elastic force of the first spring 22 acts on the launching barrel 24 through the fixing ring 23. The elastic force of the first spring 22 can make the launching barrel 24 return to its original position after the fire extinguishing bomb is fired.

[0031] Furthermore, the fixing ring 23 slides on the launching frame 21 through the launching barrel 24, and the launching frame 21 limits the position of the fixing ring 23 on the launching frame 21 through the elastic force of the first spring 22, so that the position of the launching barrel 24 on the launching frame 21 is fixed, and the position of the launching barrel 24 when firing the fire extinguishing bomb remains unchanged. However, when the launching barrel 24 fires the fire extinguishing bomb, the first spring 22 will be deformed through the fixing ring 23, thereby reducing the recoil of the launching barrel 24.

[0032] Furthermore, multiple groups of limit holes are opened on the surface of the mounting block 2, multiple groups of guide holes are opened on the surface of the fixed block 3, multiple groups of limit rods 33 are provided, and all slide on the guide holes of the fixed block 3. The elastic force of the second spring 31 acts on the limit rod 33 through the connecting plate 32, and multiple groups of limit rods 33 can be operated to slide on the fixed block 3 at the same time through the connecting plate 32.

[0033] Furthermore, a slot is provided at the bottom of the fixed block 3, and the mounting block 2 is snap-connected to the slot of the fixed block 3. The slot of the fixed block 3 is connected to the guide hole of the fixed block 3, and the limiting rod 33 passes through the limiting hole of the mounting block 2 on the slot of the fixed block 3, thereby realizing the limiting of the mounting block 2 by the fixed block 3. At this time, the mounting block 2 is fixedly installed on the fixed block 3, which is convenient for replacing the launching gun barrel 24 at the bottom of the mounting block 2.

[0034] Working principle: When a group of launching gun barrels 24 are in the process of launching fire extinguishing bombs, the launching gun barrels 24 will slide on the guide tubes of the launching frame 21 one after another. During the sliding process, the launching gun barrels 24 pull the first spring 22 to deform through the fixing ring 23, thereby reducing the recoil of the launching gun barrel 24 on the launching frame 21, thereby avoiding affecting the delivery angles of other launching gun barrels 24, ensuring the accuracy of the continuous firing of fire extinguishing bombs by the launching gun barrels 24, and further ensuring the fire extinguishing effect of the drone.

[0035] The mounting block 2 is engaged and connected to the slot at the bottom of the fixing block 3, and the second spring 31 pulls the connecting plate 32 through the elastic force. The connecting plate 32 drives multiple groups of second springs 31 to slide on the guide holes of the fixing block 3. Multiple groups of connecting plates 32 pass through the limiting holes of the mounting block 2 on the slot of the fixing block 3, thereby limiting the position of the mounting block 2 on the fixing block 3, realizing the installation of the mounting block 2 on the fixing block 3, and the launching gun barrel 24 is quickly installed on the fixing block 3 through the mounting block 2, which speeds up the replacement efficiency of the launching gun barrel 24, thereby improving the efficiency of the launching gun barrel 24 in throwing fire extinguishing bombs.
