The invention provides an icebreaking towing device for widening a channel, which comprises a central auxiliary icebreaking ship positioned right behind an icebreaking tugboat and lateral icebreaking ships symmetrically arranged on two sides behind the central auxiliary icebreaking ship to form a triangular structure taking the central auxiliary icebreaking ship as a center and the icebreaking tugboat and the two lateral icebreaking ships as vertexes, and a rigid frame for connecting the icebreaking tugboat, the central auxiliary icebreaker and the lateral icebreaker into a whole is arranged above the icebreaking tugboat, the central auxiliary icebreaker and the lateral icebreaker. Compared with a single icebreaker with the width equal to the sum of the widths of three icebreaker bodies, the icebreaking resistance is small, the channel opening width is large, the channel opening efficiency of the icebreaker can be effectively improved, and the channel opening capacity is higher compared with the single icebreaker.

    本发明提供了一种用于拓宽航道的破冰拖曳装置,包括位于破冰拖船正后方的中央辅助破冰船和位于中央辅助破冰船后方两侧对称布置的侧向破冰船,形成以中央辅助破冰船为中心,以破冰拖船和两个侧向破冰船为顶点的三角形结构,破冰拖船、中央辅助破冰船和侧向破冰船上方设置将破冰拖船、中央辅助破冰船和侧向破冰船连接为一体的刚性框架。本发明相对于宽度等于三个破冰船体宽度之和的单个破冰船的破冰阻力要小,开辟航道宽度大,可有效提高破冰船航道开辟效率,相对单个破冰船的开辟航道能力更高。
