The invention discloses a ship-borne rotary table narrow-space multi-layer anti-surge three-stage waterproof structure, and belongs to the technical field of equipment such as rotary tables and dome cameras which rotate relatively on sea transportation and river transportation carriers. A ship-borne rotary table comprises an orientation flange plate and an orientation shell, and the three-stage waterproof structure is arranged in a gap between the orientation flange plate and the orientation shell; comprising a scribing piece, a graphite ring, a friction ring, an annular groove a and an annular groove b which are arranged on an orientation shell, and an annular boss a and an annular boss b which are arranged on an orientation flange plate, the scribing sheet is arranged on the outer circumferential surface of the annular groove a in a sleeving manner; the annular boss a is positioned above the scribing sheet; the annular boss b is positioned in the annular groove a; an annular space is formed on the lower end surface of the azimuth flange plate and on the inner side of the gap; the friction ring is mounted in the annular space; the graphite ring is installed in the annular groove b and tightly pressed on the lower surface of the friction ring. A multi-layer step-by-step waterproof structure is adopted, so that waterproof sealing can be achieved, and the mounting space of the rotary table can be reduced.

    本发明公开了一种舰载转台狭小空间多层次防浪涌的三级防水结构,属于海运、河运载体上转台、球机等存在相对旋转的设备技术领域,舰载转台包括方位法兰盘和方位壳体,三级防水结构设置于方位法兰盘和方位壳体之间的间隙内,包括:划片、石墨环、摩擦环、方位壳体上的环状凹槽a和环状凹槽b、方位法兰盘上的环状凸台a和环状凸台b;划片套装在环状凹槽a的外圆周面上;环状凸台a位于划片的上方;环状凸台b位于环状凹槽a内;方位法兰盘的下端面,且在间隙的内侧形成一个环状空间;摩擦环安装于环状空间内;石墨环安装于环状凹槽b内,并压紧于摩擦环的下表面。本发明采用多层次逐级防水结构既能做到防水密封,又能缩小转台的安装空间。
