The invention discloses a sailboat sail-mounted wind power pressure relief protection system, which comprises tension sensors mounted on side supporting ropes in all directions of a supporting mast and mounted on pulleys of all sail attack angle control trimming rods, and the tension sensors are used for monitoring wind pressure borne by sails in real time during sailing; the PLC of the central control computer is used for receiving the wind pressure signal transmitted by the tension sensor and sending out an emergency pressure relief instruction when the pressure exceeds a preset safety threshold value; according to the invention, tension sensors mounted on side supporting ropes in all directions of a supporting mast and on pulleys of all sail attack angle control trimming rods are adopted to monitor wind pressure borne by sails in real time during sailing, and wind pressure signals are transmitted to a central control computer PLC (Programmable Logic Controller); when the pressure exceeds a set value, the PLC commands the electronically controlled capstan capable of rotating forwards and reversely to rotate reversely in time to loosen the trimming rod so as to reduce the stress on the sail, and meanwhile, the PLC can command the propellers on the two sides to apply different forces to control the sailboat to rotate towards a wind direction line with an optimal angle, so that the sailboat is driven to run safely.
本发明公开了一种帆船帆装风力泄压保护系统,包括:安装在支撑桅杆的各方向侧支索上和安装在各帆攻角控制缭绳滑轮上的拉力传感器,用于实时监控风帆航行时所受的风压;一个中控电脑的PLC,用于接收拉力传感器传递的风压信号,并在压力超过预设的安全阈值时发出紧急泄压指令;本发明采用安装在支撑桅杆的各方向侧支索上和安装在各帆攻角控制缭绳滑轮上的拉力传感器,实时监控风帆航行时所受的风压,并将此风压信号传导给中控电脑PLC,当压力超过设定值时PLC命令受电控的可正、反转向的绞盘及时反转松开缭绳以减少船帆上的受力,同时PLC还可命令两侧螺旋桨进行不同的出力,控制帆船往最佳角度的风向线转向,双管齐下,从而来更加保障帆船的行驶安全。
