Description

Technical Field

[0001] The utility model relates to the technical field of rotary bombing, in particular to a quick-detachable rotary bombing device mounted on an unmanned aerial vehicle. Background Art

[0002] In recent years, UAVs are increasingly being used in natural data collection, sample collection, and other fields because they are easy to deploy, can be operated contactlessly, and can carry a variety of different types of equipment. UAVs can not only carry image acquisition devices such as cameras, but also sample acquisition devices such as water dispensers. They are particularly suitable for complex environments and harsh conditions, or for situations where the sampling area is vast.

[0003] Some existing unmanned aerial vehicle bomb-dropping devices have low compatibility with bombs, and have high requirements for the bomb shapes they can accommodate, or even can only accommodate a single type. The devices are difficult to disassemble and assemble, and require tools to assist in disassembly and assembly. If a problem occurs during the operation and the equipment needs to be replaced, it is impossible to guarantee the work in a timely manner. In wartime, every second may affect the situation. It is even more impossible to improve the efficiency of the operation by replacing the magazine of a gun. The weight requirements for the bombs thrown are high, and some traditional equipment has weak mechanical strength and cannot operate smoothly, and even the phenomenon of bullets falling out and misfiring may occur. There is no auxiliary throwing pod, and it relies solely on the naked eye or positioning system for delivery. The delivery accuracy is low, and even the target error may occur, which is extremely dangerous. It cannot be used at night because there is no infrared system and it cannot operate in the dark environment at night. The loading speed in the device is slow and inefficient, and it is necessary to load from the bottom up. First, find the correct cartridge, and at the same time consider the loading angle and other issues. The status of the bomb-hanging module must also be considered. Whether the ammunition can be locked safely and reliably takes a long time; the number of stored ammunition in the device is small, and the existing equipment generally has 4 or 6 ammunition, which means the number of stored ammunition is small; multi-channel control occupies more channels, and each ammunition tube requires a signal channel control. Assuming a 6-tube device, 6 channels are required to control, which greatly reduces other functionality; the more control channels, the lower the fault tolerance and the higher the failure rate, and it is easy for a certain ammunition tube to fail to drop bombs normally; the horizontal arrangement takes up a large space, and due to the heavy weight of the dropped bombs, the center of gravity of the aircraft changes after a few bombs are dropped, affecting the stability and controllability of the aircraft, and even causing the entire aircraft to fall in severe cases.

A servo drive shaft 204 is provided on one side of the rotating wheel 201. Multiple card slots 208 are provided outside the rotating wheel 201. A servo gear set 206 is provided at the top of the rotating wheel 201.

[0035] Please refer specifically to Figure 1 and 2 , the rotating wheel 201 is rotationally and limit-connected to the housing 101 through the servo drive shaft 204 and the fixed rod 104, which facilitates the installation and disassembly of the rotating wheel 201 and also provides a certain degree of support.

[0036] Please refer specifically to Figure 1 , 2 and 3. Multiple pins 103 are provided inside the pan-tilt mounting bracket 102. The pan-tilt mounting bracket 102 is detachably connected to the housing 101 through the multiple pins 103, and different pan-tilt mounting brackets 102 can be replaced, which is relatively convenient to use. At the same time, the practicability is relatively strong.

[0037] Please refer specifically to Figure 3 , the servo gear set 206 is meshed and connected with the multiple card slots 208 for linkage to limit the rotating wheel 201, and greatly ensures the stability and reliability of the operation of this device.
