The underwater preset launching device for the unmanned aerial vehicle comprises a balance weight throwing device, a stable floating mechanism and an unmanned aerial vehicle launching bin, the front end of the stable floating mechanism is connected with the unmanned aerial vehicle launching bin, and the rear end of the stable floating mechanism is connected with the balance weight throwing device; the counterweight throwing device is used for throwing the counterweight; the stable floating mechanism comprises a base, an air cylinder, a connecting disc, a double-hole connecting rod and a buoyancy arm. The air cylinder rod pushes the connecting disc to move in the vertical direction along a radial groove hole in the base under the action of air pressure, the air cylinder rod moves downwards to enable the buoyancy arms to be unfolded, and the air cylinder rod moves upwards to enable the buoyancy arms to be folded. The unmanned aerial vehicle launching bin comprises a cylindrical launching barrel, an unmanned aerial vehicle base, a launching bin sealing cover and an air guide pipe, the unmanned aerial vehicle base and the cylindrical launching barrel form a transient sealed space before launching to serve as a low-pressure chamber, and a folding unmanned aerial vehicle is placed in the cylindrical launching barrel. The device is small in size, low in cost and easy to equip in various offshore platforms or carry by divers.

    本发明提供一种用于无人机的水下预置式发射装置,包括配重抛离装置、稳定漂浮机构和无人机发射仓,所述稳定漂浮机构前端与无人机发射仓连接,后端与配重抛离装置连接;所述配重抛离装置实现配重的抛离;所述稳定漂浮机构包括底座、气缸、连接盘、双孔连杆和浮力臂;气缸杆在气压的作用下推动连接盘沿着底座中径向槽孔做竖直方向上的位移,气缸杆向下运动使浮力臂展开,向上运动使浮力臂合拢;所述无人机发射仓包括圆柱发射筒、无人机底座、发射仓密封盖和导气管,所述无人机底座与圆柱发射筒在发射前形成短暂密封空间作为低压室,圆柱发射筒里放置有折叠无人机。本发明体积小、成本低,易于在各种海上平台中装备,或者由潜水员携带。
