This invention discloses a landing buffer device for unmanned aerial vehicles (UAVs), relating to the field of aviation equipment technology. By integrating the roller body and the sliding plate as two grounding structures onto the landing gear, the device can quickly switch operating modes according to ground conditions through the linkage of the piston cylinder and piston rod. On flat ground, the roller is used first to reduce gliding resistance, while on muddy or slippery ground, the sliding plate is used for grounding, effectively preventing roller jamming and enhancing all-terrain adaptability and landing safety. Simultaneously, the mechanical buffer composed of a second and third spring, combined with the hydraulic damping buffer composed of buffer components, forms a highly efficient double-layer energy-absorbing buffer structure, which to a certain extent alleviates the damage to the aircraft and equipment caused by landing impact, thus improving the landing safety of the UAV.

This invention relates to the field of explosive loading device technology, specifically to an adjustable explosive loading device and method with segmented charge quantity within an orifice. The device includes a loading rack, which comprises a base plate and two side plates fixed to the base plate. Multiple explosive cartridges are arranged inside the loading rack, each containing a blasting charge. A storage rack is fixed to the bottom of each cartridge, and an air-isolating bag is fixed inside the storage rack. The air-isolating bag, when unfolded, fills the gap between two cartridges. Slider blocks are fixed to both sides of each cartridge, and these sliders are slidably connected to the side plates of the loading rack. The beneficial effect is that, through the pre-reserved slots on the side plates of the loading rack and their cooperation with the sliders, each cartridge can be independently adjusted up and down along the side plates of the loading rack, and its position is locked by inserting a hand-tightened screw into a positioning hole. This allows the spacing between adjacent charge quantities to be flexibly adjusted according to the blasting design and prevents displacement during transport and deployment, solving the problem of fixed and unadjustable segmented positions in existing technologies.
