The invention provides an annular on-orbit propellant screen collector and a surface tension storage box, and relates to the field of propellant parts. The annular on-orbit propellant screen collector comprises a collector framework and collector screen windows, and the collector screen windows are distributed on the collector framework; a plurality of rectangular windows which are evenly distributed in the circumferential direction are formed in the collector framework, and the collector screen window is in clearance fit with the rectangular windows. The manufacturing process is simple, the screen assembly structure is modularized, that is, the large-area screen structure is equally divided into small sheet-shaped rectangular flat plate structures, the rectangular flat plate structures are the simplest screen assemblies, the manufacturing process is most mature, and the problem that the large-size screen assembly is prone to being damaged due to integrated manufacturing is solved; test and maintenance are convenient, when a certain collector screen window is damaged or the performance is unqualified, the collector screen window can be cut off, the collector screen window with the qualified welding performance is replaced again, and the problem that a large-size screen assembly is prone to being damaged and cannot be maintained due to integrated manufacturing is solved.

    本发明提供了一种涉及推进剂零件领域的环形在轨推进剂筛网收集器和表面张力贮箱,包括收集器骨架和收集器筛窗,收集器筛窗分布在收集器骨架上;收集器骨架上设有环向一周均布的多个矩形窗口,收集器筛窗与矩形窗口间隙配合。本发明制造工艺简单,将筛网组件结构模块化,即将大面积的筛网结构均分成小的片状矩形平板结构,矩形平板结构为最简单的筛网组件,制造工艺也最为成熟,解决大尺寸筛网组件一体化制造容易受到损伤的问题;本发明便于测试维修,某个收集器筛窗筛网收到破坏或者性能不合格,可以将该片收集器筛窗切割下来,重新更换焊接性能合格的收集器筛窗,解决大尺寸筛网组件一体化制造容易受到损伤不能维修的问题。
