The splash-proof device is characterized in that a toggle plate matched with the splash-proof strip I in length is arranged below the splash-proof strip I, the lower side of the toggle plate is fixedly connected with a shell of the high-speed catamaran, an included angle between the toggle plate and the shell of the high-speed catamaran is 45 degrees, and the upper side of the toggle plate is fixedly connected with the middle part of the lower surface of the splash-proof strip I.
The bracket with the shell of high-speed double hull adopts the angle welding mode to carry out fixed connection, the bracket with the lower surface middle part of splashproof strip I also adopts the angle welding mode to carry out fixed connection.
The splash-proof strip I is of an integrated structure formed by an upper plate I and a lower plate I, one side of the lower plate I is fixedly connected with a shell of the high-speed catamaran, the lower plate I is parallel to a base line of the high-speed catamaran, one side of the upper plate I is fixedly connected with the shell of the high-speed catamaran, the other side of the upper plate I is intersected with the other side of the lower plate I and is fixedly connected with the other side of the upper plate I, the inner surface of the fixed connection position of the upper plate I and the lower plate I is provided with a fillet, and the outer surface of the fixed connection position of the upper plate I and the lower plate;
the splash-proof strip II is of an integrated structure formed by an upper plate II and a lower plate II, one side of the lower plate II is fixedly connected with the shell of the high-speed catamaran, the lower plate II is perpendicular to the shell of the high-speed catamaran, one side of the upper plate II is fixedly connected with the shell of the high-speed catamaran, the other side of the upper plate II is intersected with the other side of the lower plate II and is fixedly connected with the other side of the lower plate II, the inner surface of the fixed connection position of the upper plate II and the lower plate II is provided with a fillet, and the outer surface of the fixed connection position of the upper plate II and the lower plate II.

The height difference between the splash-proof strip I and the splash-proof strip II is 800 mm-1200 mm.
According to the invention, two groups of splash bars (namely the splash bar I and the splash bar II) are arranged on the high-speed catamaran, so that the ship can obtain better drag reduction effect and rolling performance, and when the splash bar I and a horizontal plane form a small-angle inclination angle to enable the bow of the ship to form splash splashing, water in the splash bar I can be quickly discharged. The lengths of the splash-proof strips I and II are selected, so that the problems that the splash-proof strip with too short length is not obvious in the process of inhibiting the splashing of the bow, and the excessive length of the splash-proof strip can cause the excessive heaving and trim and the like can be solved. After the horizontal splash-proof strips are arranged along the break lines, the horizontal splash-proof strips are beneficial to resistance and rolling performance, but the turning roll angle is larger when the steering angle is small, so that the steering is adversely affected. If the horizontal splash guard bar is changed into the vertical splash guard bar, the rotary roll can be improved properly, but the speed of the boat is lost, and the roll performance in the stormy waves is poor. Therefore, by adopting a mode of combining the horizontal splash-proof strip and the vertical splash-proof strip (namely the splash-proof strip I and the splash-proof strip II), the navigation speed and the rolling performance cannot be lost when the splash is small, a small gyration roll angle can be obtained when the splash is large, and the operation danger in stormy waves is reduced.
Based on the reason, the invention can be widely popularized in the fields of splash bars and the like.
