This invention discloses a pipeline gas supply device, a pipeline gas filling method, and a pipeline welding method, relating to the field of welding tool technology. The pipeline gas supply device includes a gas supply pipe, which comprises a hollow gas supply pipe body and a sealing plate located at one end of the gas supply pipe body, with the other end of the gas supply pipe being the gas supply end; a sealing sleeve fitted around the outer circumference of the gas supply pipe; two fixing washers, located at opposite ends of the sealing sleeve; a pushing component located at the gas supply end of the gas supply pipe; and an expansion / contraction component. The pushing component moves towards the sealing plate end of the gas supply pipe, causing the expansion / contraction component to be squeezed by the fixing washers and the sealing plate or the pushing component, achieving a pipeline sealing effect. This device limits the gas filling range of the protective gas to between the two expansion / contraction washers, greatly reducing the amount of gas used for welding, preventing free discharge of the protective gas, enabling quantitative use of the protective gas, and reducing waste. It is applicable to the gas filling of welded bends, long pipes, and irregularly shaped pipelines.

This utility model relates to the field of unmanned aerial vehicle (UAV) technology and discloses a self-adjusting landing structure for UAVs. The structure includes a UAV body, a mounting base fixedly mounted on the UAV body, a mounting plate at the bottom of the mounting base, grooves and slots on the outer wall of the mounting plate, a locking disc on the outer wall of the mounting plate, and a locking rod on the outer wall of the mounting plate. Through the linkage design of the buffer airbag and the air outlet component, adaptive adjustment to different ground hardness is achieved. When the UAV lands, the internal air pressure of the buffer airbag increases after being compressed, and the pressure pushes the sealing plate to slide open the air hole for pressure relief. The greater the impact force, the larger the air hole opening, the faster the pressure relief speed, and the stronger the buffering effect. Whether it is the high impact of hard cement ground or the continuous compression of soft sand, this structure can dynamically adjust the buffering force to avoid excessive vibration or sinking of the fuselage, effectively protecting the precision equipment inside the UAV and significantly improving landing safety.
