Description

Technical Field

[0001] This utility model relates to a bomb-throwing device mounted on a drone. Background Technology

[0002] As my country's total forest resources continue to grow, the scope of fire risk is gradually expanding, especially in key forest areas such as the Lesser Khingan Mountains and Changbai Mountains, where the amount of combustible material far exceeds the critical value for major forest fires. Once extreme weather conditions such as high temperatures and strong winds occur, fires are highly likely to break out. Furthermore, my country's forests have many complex terrains, making it difficult for fire trucks and personnel to quickly reach the fire scene. The transportation of firefighting equipment and supplies is also restricted. The total number of forest aerial firefighting aircraft is insufficient, and the need for human piloting poses significant safety risks. Therefore, using small drones to carry ammunition for long-distance firefighting has become a trend in forest fire prevention. However, most ammunition carrying methods currently on the market use a hook-type system. This method has specific requirements for the structure and shape of the firefighting ammunition, which must meet hook conditions. Moreover, the structure cannot coordinate the simultaneous deployment of multiple ammunition, resulting in low efficiency in a single firefighting operation. The firefighting ammunition cannot maintain stability during drone flight, affecting the drone's flight attitude and increasing the risk of crashes. Exposed firefighting ammunition is also susceptible to performance impacts from uncertain external natural factors.
