The invention discloses a deep sea towed body emergency obstacle avoidance mechanism and a control method thereof. The emergency obstacle avoidance mechanism comprises a deceleration turning mechanismand an emergency stop mechanism, a motor is used for driving side wings to rotate and is matched with a propeller to achieve the deceleration function and the turning function of the deceleration turning mechanism, and the emergency stop mechanism releases a drag parachute; the emergency stop function of the emergency stop mechanism is achieved through fluid resistance of the drag parachute, thedefects of hysteresis, complex operation, low efficiency and the like of a traditional method for avoiding obstacles by retracting and releasing a towing cable and adjusting the ship speed are overcome, and it is guaranteed that the towed body can intelligently, autonomously and continuously complete emergency obstacle avoidance when encountering sudden-change seabed terrains such as sea mountains. The response speed and the obstacle avoidance efficiency of the towed body during emergency obstacle avoidance are improved, the control flow of the emergency obstacle avoidance mechanism is closed-loop control, real-time and continuous obstacle avoidance can be performed through the emergency obstacle avoidance mechanism, the workload and the working cost are reduced, the working efficiency isimproved, and the probability of equipment damage is reduced.

    本发明公开一种深海拖体应急避障机构及其控制方法,所述应急避障机构包括减速变向机构和急停机构,利用电机带动侧翼旋转并配合推进器实现减速变向机构的减速功能和变向功能,急停机构通过释放阻力伞,并利用阻力伞的流体阻力实现急停机构的急停功能,克服传统的通过收放拖缆和调节船速进行避障的方法的滞后性以及操作繁琐、效率低下等缺点,保证拖体在遇到海山等突变海底地形时可智能、自主、连续的完成应急避障,提高拖体在应急避障时的响应速度和避障效率,且该应急避障机构控制流程为闭环控制,可通过应急避障机构进行实时、连续避障,不仅减少工作量和工作成本,而且提高作业效率,降低设备受损的几率。
