The invention relates to the technical field of equipment for trailing suction dredgers, and discloses a wave compensation device for a trailing suction dredger. The wave compensation device comprises a ship, an air pump, a winding device and a winch, and a fixed frame is fixedly installed on the side wall of the ship. Through the arrangement of an air-floating cylinder and a cavity expanding cylinder, the sizes of expanded bodies of the air-floating cylinder and the cavity expanding cylinder are changed, required pulling force is directly provided for a drag head in water, when the ship fluctuates up and down under the influence of waves, a water tank moves up and down relative to the air-floating cylinder, and the expanded bodies of the air-floating cylinder and the cavity expanding cylinder continuously suspend and do not move. The influence of external waves is effectively avoided, relatively stable pulling force is continuously provided for the drag head, fluctuation of the drag head is reduced, and then the working efficiency of the drag head is improved. Meanwhile, as the water tank is movably connected with the air flotation cylinder in a sleeving mode, when the ship moves, the drag head can be directly pulled to synchronously move, and the phenomenon that when the drag head is directly connected with the ship, the drag head is interfered by the waves in the vertical direction and is also interfered by the horizontal tension of the pressed ship is avoided.
本发明涉及耙吸式挖泥船用设备技术领域,且公开了一种耙吸式挖泥船用波浪补偿装置,包括船、气泵、收卷装置和绞车,所述船的侧壁上固定安装有固定架。通过气浮筒和扩腔筒的设置,使得通过改变气浮筒与扩腔筒展开体的大小,直接在水中为耙头提供所需拉力,可在船受到波浪的影响进行上下起伏时,水箱相对气浮筒进行上下运动,而气浮筒与扩腔筒的展开体持续悬浮不动,有效避免外界波浪的影响,持续为耙头提供相对稳定的拉力,减少耙头的波动,进而增加耙头的工作效率,同时,由于水箱与气浮筒为活动套接,使得当船移动时,可直接拉动耙头同步移动,避免耙头直接与船连接时,即受到波浪垂直方向的干扰,又受压船水平方向的拉力干扰。
