    • A trawl door (2) for remote-controlled adjustment under water of the active surface area of the trawl door (2). The trawl door (2) comprises an upper and lower surface portion dis- posed on either side of a central axis (6). Each surface portion is provided with an opening (10a, 10b) with an associated, movable damper (12a, 12b) structured in a manner allowing it to be moved, completely or partially, over the opening (10a, 10b). The distinctive characteristic of the trawl door (2) is that said surface portions have a hydrodynamic shape and are comprised of an upper and lower wing (A,B) disposed on either side of a tube (4) formed about the central axis (6); - wherein each damper (12a, 12b) is structured movable along an axis (24) extending transversely to the central axis (6); - wherein each damper (12a, 12b) is movably connected to a driving device.(28a, 28b); and - wherein the central tube (4) comprises a remote-controlled communication and control means (32) for individual operation of each driving device (28a, 28b).
    • 拖网门(2),用于在拖网门(2)的活动表面区域的水下进行遥控调节。 拖网门(2)包括分布在中心轴线(6)两侧的上表面部分和下表面部分。 每个表面部分设置有具有相关联的可移动阻尼器(12a,12b)的开口(10a,10b),该阻尼器(12a,12b)以允许其完全或部分地在开口(10a,10b)上移动的方式构造。 拖网门(2)的独特特征是所述表面部分具有流体动力学形状,并且包括设置在围绕中心轴线(6)形成的管(4)的任一侧的上翼和下翼(A,B) ); - 其中每个阻尼器(12a,12b)被构造为沿着横向于所述中心轴线(6)延伸的轴线(24)移动; - 其中每个阻尼器(12a,12b)可移动地连接到驱动装置(28a,28b)上。 和 - 其中所述中心管(4)包括用于每个驱动装置(28a,28b)的单独操作的遥控通信和控制装置(32)。
