The invention belongs to the technical field of underwater unmanned aerial vehicle launching, and discloses a cylinder sealing cover structure for unmanned aerial vehicle underwater launching in order to solve the problem that in the prior art, the pressure bearing capacity and the breaking resistance of a cylinder cover are difficult to balance, and the cylinder sealing cover structure comprises a lower sealing cover, an upper sealing cover, a fragile piece and a plurality of leaf separating covers; center holes are formed in the centers of the lower sealing cover and the upper sealing cover; the upper sealing cover is fixedly arranged on the lower sealing cover, and the fragile piece is connected with the lower sealing cover in a sealing mode through the first sealing ring and located above the upper sealing cover. Each leaf separation cover is rotationally connected with the upper sealing cover through a rotating shaft, and is distributed below the fragile piece in a central symmetry manner; the lower portion of the side wall of the side, connected with the upper sealing cover, of each leaf separating cover makes close contact with the inner wall of the center hole of the lower sealing cover, and then the leaf separating covers are limited to only rotate upwards in one direction. The external pressure resisting capacity of the barrel cover is improved, meanwhile, the breaking resistance is reduced, and the high internal and external load ratio is achieved.

    本发明属于水下无人机发射技术领域,为了解决现有技术中筒盖在承压能力和破碎阻力之间难以平衡的问题,公开了一种用于无人机水下发射的筒密封盖结构,包括:下密封盖、上密封盖、易碎片和多个分叶盖;下密封盖和上密封盖中心均设置有中心孔;上密封盖固定设置在下密封盖上,易碎片通过第一密封圈与下密封盖密封连接并位于上密封盖上方;各个分叶盖分别通过一根转轴与上密封盖转动连接,并呈中心对称分布设置在易碎片下方;各个分叶盖与上密封盖连接一侧的侧壁下方与下密封盖的中心孔内壁紧密接触,进而限制分叶盖使其只能向上单向转动。本发明提高了筒盖的抗击外部压力能力,同时降低了冲破阻力,具有较高的内外载荷比。
