The invention belongs to the technical field of underwater towing detection, and particularly relates to a heave compensation device for a towing platform. A passive heave compensation device comprises a frame, a movable fairlead, a fixed fairlead and a guide rod sleeved with a spring. The fixed fairlead wheel and the movable fairlead wheel are installed in the frame, one end of the guide rod penetrates through the movable fairlead wheel, the other end of the guide rod is fixedly connected with the fixed fairlead wheel, and long kidney-shaped guide grooves for limiting the travel of the movable fairlead wheel are formed in the two sides of the frame. The passive heave compensation device is installed between the winch and the stern fairlead device, and after being released from the winch, the towrope is wound around the fixed fairlead wheel by a half circle and then wound around the movable fairlead wheel by a half circle to the stern fairlead device. According to the method, the tension of the towing cable does not need to be measured in real time, only the proper spring needs to be additionally arranged according to the estimated working load, and in the heaving process of the towing platform, the heaving motion of the towing platform can be compensated automatically according to the change extension and compression of the tension of the towing cable.

    本发明属于水下拖曳探测技术领域,具体涉及一种拖曳平台升沉补偿装置。一种被动升沉补偿装置,包括:框架、移动式导缆轮、固定式导缆轮、套接有弹簧的导向杆;固定式导缆轮与移动式导缆轮安装在框架内,导向杆的一端穿过移动式导缆轮,另一端与固定式导缆轮固定连接,框架两侧设有限制移动式导缆轮行程的长腰形导向槽;被动升沉补偿装置安装在绞车与船尾导缆装置之间,拖缆从绞车上放出后,先在固定式导缆轮上盘绕半圈绕回,再在移动式导缆轮上盘绕半圈绕出至船尾导缆装置。本发明不需要实时测量拖缆张力,仅需根据估算的工作载荷,加装合适的弹簧,当拖曳平台升沉过程中,会自动根据拖缆张力的变化伸长及压缩,对拖曳平台升沉运动进行补偿。
