The marine mast lamp shading device comprises a shading cover and a mast, the shading cover is arranged on a marine mast lamp in a covering mode and comprises a rear shading plate, a bottom plate, a top plate, a first side shading plate and a second side shading plate, the rear shading plate is of an arc-shaped plate-shaped structure, the radian of the rear shading plate is smaller than 0.75 pi, the bottom plate is connected with the lower end of the rear shading plate, and the top plate is connected with the bottom plate. The top plate is connected with the upper end of the rear shading plate, the first side shading plate is connected with the lower end of the top plate, the second side shading plate is connected with the upper end of the bottom plate, and the height of the rear shading plate is larger than the sum of the height of the first side shading plate and the height of the second side shading plate, so that a light-transmitting gap is formed between the first side shading plate and the second side shading plate. One end of the mast is fixedly connected with the ship, and the other end is fixedly connected with the bottom of the bottom plate. According to the invention, uninterrupted light can be ensured to be displayed in a 225-degree horizontal light arc, the situation that the light irradiates a radar and is projected to a deck to form a constantly rotating shadow is avoided, and inconvenience brought to sailors due to the fact that the light directly irradiates the deck can be effectively prevented.

    本发明公开了一种船用桅灯遮光装置,包括遮光罩和桅杆,遮光罩罩设在船用桅灯上,遮光罩包括后遮光板、底板、顶板、第一侧遮光板和第二侧遮光板,后遮光板为弧形板状结构,后遮光板的弧度小于0.75π,底板与后遮光板的下端连接,顶板与后遮光板的上端连接,第一侧遮光板与顶板的下端连接,第二侧遮光板与底板的上端连接,后遮光板的高度大于第一侧遮光板和第二侧遮光板的高度之和,从而使第一侧遮光板和第二侧遮光板之间形成透光缝隙,桅杆的一端与船舶固定连接,另一端与底板的底部固定连接。本发明能够确保在225°的水平光弧内显示不间断灯光,避免桅灯光照射到雷达投影到甲板上形成一直旋转的阴影,能有效防止灯光直射到甲板上给船员带来不便。
