The invention relates to a propelling device which comprises a main frame body, a circular top plate is arranged at the top of the main frame body, a ring piece is arranged at the bottom of the main frame body, and the bottom of the top plate and the top of the ring piece are connected through a plurality of supporting columns with the same height; a power device is arranged in the middle of the bottom of the top plate; the lower portion of the main frame body is provided with a protective cover, the bottom of the protective cover is provided with an annular air bag correspondingly matched with the ring piece, the protective cover is provided with a plurality of transverse screw rods between the supporting columns, and the screw rods are located above the ring piece. During take-off, the ring piece can lift up the screw rod when rising, and then the screw rod enables the protective cover and the annular air bag to rise together. The product is simple in structure, convenient to maintain and assemble and suitable for different flight equipment such as airships and airplanes, and especially due to the design of the U-shaped groove of the protection cover, the screw and the built-in annular air bag, the product can slowly land during landing, a good buffering protection effect on the whole product is achieved, and therefore the service life of the product is prolonged.

    本发明涉及一种推进装置,包括主架体,主架体的顶部设有圆形的顶板,主架体的底部设有环件,顶板的底部与环件的顶部之间通过若干个等高的支柱相连接;顶板的底部中间位置设有动力装置;主架体的下部设有保护罩,保护罩的底部设有一个与环件对应配合的环形气囊,保护罩在所述支柱之间设有若干个横向的螺杆,螺杆位于环件的上方位置。起飞时,环件上升时会一并托起螺杆,所述螺杆进而将保护罩与环形气囊一并连带升起。本产品结构简单、维修组装方便,适用于飞艇、飞机等不同飞行设备,尤其是保护罩U形凹槽、螺杆和内置环形气囊的设计,可以使本产品在降落时缓慢落地,对整个产品起到良好的缓冲保护作用,从而延长产品的寿命。
