摘要： An inlet screen for an ocean thermal power plant has an outer side parallel to the ocean current and a plurality of parallel bars extending at an acute angle to the horizontal, wherein the acute angle opens toward the upstream direction of the current. The total area of through openings in the inlet screen receive the predetermined flow requirement of the power plant at a velocity no greater than 0.5 feet per second, so that fish are not sucked against the screen. The vertical spacing between the bars is no greater than one-half of the inner diameter of tubes in heat exchangers in the plant. The spacing between bars is at a minimum at the outer side of the screen, and the spacing increases between the outer side and the inner side, so that objects do not become wedged between the bars. The inlet screen extends sufficiently below the ocean level to accommodate the plant's water flow requirement at a velocity of no greater than 0.5 feet per second, and extends sufficiently above the ocean level to dissipate the energy of ocean waves as they strike walls of the plant, so that the total form of the waves on the plant is reduced.

摘要翻译： 用于海洋火力发电厂的入口屏幕具有平行于海洋电流的外侧和与水平方向成锐角延伸的多个平行杆，其中锐角朝向电流的上游方向打开。 入口屏幕中的通孔的总面积以不大于0.5英尺/秒的速度接收发电厂的预定流量要求，使得鱼不会被吸到屏幕上。 杆之间的垂直间距不大于工厂内热交换器管内径的一半。 杆之间的间隔在屏幕的外侧处最小，并且间隔在外侧和内侧之间增加，使得物体不会楔入杆之间。 入口屏幕充分延伸到海平面之下，以适应不超过0.5英尺每秒的速度的植物的水流量需求，并且充分延伸到海洋水平以消散海浪冲击植物的墙壁时的能量， 使得植物上的波浪的总体形式减少。
