Embodiment Construction
[0025] The invention installs an angular displacement sensor in the cabin, and through the signal transmitted back from the sensor, combined with the ship's sway data, after analysis and calculation, an instruction is sent to the hydraulic control system to change the deflection angle of the stabilizer fins. The installation structure of the stabilizer fins, the installation method of the sensor and the calculation method of the feedback control are not the focus of this application, and will not be repeated here.
[0026] Such as figure 1 , figure 2 , image 3 Shown, is the structural representation of hydraulic system of the present invention, and its main structure comprises:
[0027] A two-way variable pump 915 is the main power source, which is connected to the oil inlet of the first hydraulic control check valve 991 and the second hydraulic control check valve 992 through the first power oil circuit 9151 and the second power oil circuit 9152 respectively. The oil inl...
