JPH0769282A - Capsizal preventing device having wing ring on hull - Google Patents

Abstract

PURPOSE:To improve the capsizal preventing effect of a hull by fitting tubular keels on the starboard side and the port side of a hull, mounting wing-like rings on them through supporting bars, and fixedly securing a tubular balance keel on the ship's bottom part. CONSTITUTION:Tubular keels 8 are fitted to the starboard side and the port side of a hull 1, supporting bars 9 are fixedly secured on the outermost side of them and the bottom part of the hull 1, and structural wing rings 2 of section similar to that of an aerofoil are fitted to two positions before and behind of the hull 1 through the supporting bars 9. A plate-shaped keel 5 is fitted to the bottom part of the hull 1, and a tubular balance keel 4 extending in the lengthwise direction of the hull is fitted to the lower end part of the keel 5. The wing ring 2 is formed with an introducing groove 10 on the inside, the supporting bars 9 are joined with the introducing groove 10, and the ring 2 supports the hull 1 so as to swing inside the wing ring 2 through the supporting bars 9.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Use The present invention relates to a hull capsize prevention device. (B) Conventional technology The hull was designed to have a low center of gravity and equipped with a balance tank, etc. In addition, a gyro stabilizer etc. were also adopted. (C) Problems to be solved by the invention In the conventional technology, the resilience of the characteristics of the hull is inferior depending on the weather conditions. (D) Means for Solving the Problems This invention will be described with reference to the drawings. Referring to FIG. 1, a tubular keel 8 is attached to the starboard side of the hull 1 and a support rod 9 is fixed, and a guide groove 10 and a support rod are attached. 9 and 9 are joined to each other to form an inner ring of the wing ring 2 and a hull 1 is formed as shown in FIG. 3 and a plate-shaped keel 5 is attached 5 and a tubular balance keel 4 is attached, as shown in FIG. 1, FIG. 2 and FIG. As shown. (E) Operation Even if the hull constructed as described above receives a large wave force on the port side during navigation (Fig. 3), as shown in Fig. 3, the winged ring 2
The hull remains stable in the ring of the winged ring 2 which is above and below the water surface with respect to the water surface, and the winged ring 2 acts differently. On the former water surface, the winged ring 2 exerts air resistance. It acts to lift the hull by receiving the lift, and the latter is below the surface of the water, and the wing ring 2 receives the resistance of water to obtain the buoyancy. The winged ring 2 of the hull that approaches the water surface to reduce the resistance of the hull and facilitates the acceleration of the hull has the different functions of the former and the latter. Great synergistic effect with keel 4. (F) The winged ring 2 of the embodiment has a structure similar to the cross section of the flight wing as shown in FIGS. 1 and 2, and the winged ring 2 is manufactured in the same manner as this wing, and the wing is hollow. Then, the inner side of the ring of the wing-shaped ring is provided with the guide groove 10 so that the hull sways (swings) through 9 inside the ring. (G) Effect of the Invention As described above, the present invention has the effect of preventing the capsizing of the hull by the action of the functions of the wing ring 2, the tubular keel 8, the plate keel 5, the tubular balance keel 4, and the like on the hull.
