Detailed Description
The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention.
Referring to fig. 1, the stability augmentation tailboard mechanism 2 suitable for small and medium-sized ships is installed at the tail of a ship body 1, is suitable for small and medium-sized ships with short waterline, wide and flat rear end face, large height and enough space for arranging matched equipment, and is particularly suitable for small and high-speed catamarans. The method is mainly used for improving the wave resistance of the ship body 1, reducing the sailing resistance and finally improving the sailing stability and the running speed of the ship.
During running of the vessel, transversely extending waves are encountered, which results in a tilting of the hull 1 in the direction of the longitudinal axis, the cosine of the tilt angle being equal to the ratio of the wave height to the waterline length of the hull 1. I.e. the larger the wave height, the smaller the waterline length of the hull 1, the larger the resulting inclination angle. Since the waves are usually a plurality of waves which meet the hull 1 in sequence, the hull 1 is periodically jolt with negligence, and the inclination and jolt can have serious adverse effects on the hull structure, the ship-borne equipment, the loaded cargoes and the personnel on the ship, and serious phenomena such as deformation damage of the hull 1, shedding damage of the equipment and the cargoes, displacement collision, dizziness and incapacitation of the personnel can occur. Generally, a large ship can utilize the advantage of longer self hull to reduce the influence of wind waves. And the small and medium-sized ships are affected more greatly. In order to reduce the sway and jolt and improve the smoothness of the ship, as described in the background art, many methods are adopted, which can partially reduce the sway and jolt of the ship in the longitudinal direction, but the existing stability augmentation tail plates are mostly of fixed structures or are adjustable in one dimension, so that the stability augmentation effect is poor, and the stability augmentation tail plates can not realize multi-dimensional adjustment, so that considerable resistance is brought, and particularly, the ship sails at a higher speed. In order to solve the problem and improve the running stability of small and medium-sized ships, the invention provides the ship stability augmentation tail plate mechanism 2 which is additionally arranged at the stern and can be folded when not in use, wherein the extension distance and the water receiving angle are adjustable. The mechanism not only can increase the wind and wave resistance of the ship body 1, but also can reduce the running resistance of the ship body 1, and can be used as an auxiliary mechanism for loading and unloading cargoes.

The shape of the water pressing plate 7 can be set according to specific requirements, in this embodiment, the water pressing plate 7 is of a rectangular plate structure, and hinge mounting seats are fixed on four corners of the upper end face of the water pressing plate. The installation seats at the two sides of the outer end of the water pressing plate 7 are hinged with the inner edge beam 5 at the side where the installation seats are arranged through pin shafts. The mounting seats at the two sides of the inner end of the water pressing plate 7 are hinged with the end parts of cylinder rods of the second hydraulic cylinders 6 at the side where the mounting seats are located through pin shafts. When the two second hydraulic cylinders 6 are simultaneously telescopic, the water pressing plate 7 rotates around the hinge pin shaft of the water pressing plate and the inner edge beam 5, so that the angle adjustment of the water pressing plate 7 is realized.
