灰色3D线框航标浮标模型

单幅竖版3D建模线框风格技术展示图，中心构图，主体是一座航标灯浮标。顶部为粉红色透明圆柱形灯罩，周围有环形金属护栏和格栅平台；中部为灰色金属桁架塔，交叉斜撑连接，塔内可见锥形灯体结构；下部为大型圆柱形浮体，表面有纵向网格线与多个系泊环；底部为较窄的圆柱底座。整体材质为灰色哑光金属与半透明粉色灯罩，表面覆盖细密3D网格线框。背景为纯净浅灰色，无环境杂物，无人物。采用正面偏高的单视角展示，主体完整居中，柔和均匀棚拍光线，突出结构轮廓与线框细节，画幅比例接近9:20。

Single vertical 3D modeling wireframe style technical display image, centered composition, featuring a navigation buoy. The top has a pink transparent cylindrical lamp housing surrounded by a circular metal railing and grid platform; the middle is a gray metal truss tower with diagonal cross braces and a conical lamp body inside; the lower part is a large cylindrical float with vertical mesh lines and multiple mooring rings; the bottom is a narrower cylindrical base. Overall materials are gray matte metal and translucent pink lamp cover, with fine 3D mesh wireframe over the surfaces. Plain light gray background, no environmental clutter, no people. Front-elevated single view, full subject centered, soft even studio lighting, emphasizing structural contours and wireframe details, aspect ratio close to 9:20.
