Embodiment 1

[0028] It can be seen from the contents of the invention that a wave-resistant catamaran consists of two hulls 1, a deck bridge 2 connecting the two hulls 1, a superstructure 3 provided above the deck bridge, and installed on the main body of the two hulls 1. The anti-wave device 4 on the outside of the area is composed of the bows of the two hulls 1, which are tip subheads 6 in the shape of triangular cones; the tip subdivision head 6 is attached with a wave-passing device 5; the waterline design of the anti-wave catamaran is in On the central horizontal plane between the triangular plane 6-3 at the upper end of the tip diverter 6 and the bottom plane of the deck bridge 2, its structure is as follows: figure 1 shown.

[0029] .The two hulls 1 of the present invention, the bow of each hull is set as a triangular pyramid-shaped tip water diversion head 6, a triangular surface 6-2 in the triangular cone and the hull straight plate hull 8 inclined towards the bottom of the ship a...

Embodiment 2

[0032] The anti-wave device 4 installed on the ship according to the present invention is composed of a plurality of anti-wave devices, the number of anti-wave devices is determined by the total length of the hull; each group of anti-wave devices is composed of anti-wave impact plates 4-1, 4-2 and the shaft rods 4-3, 4-4 fixed on the anti-wave impact plate and the spring return device 4-5; the horizontal center line of the anti-wave impact plate 4-1, 4-2 in each group of anti-wave impact device waterline.

[0033] .In the anti-wave device 4 installed on the ship according to the present invention, the anti-wave impact plates 4-1 and 4-2 of each group of anti-wave devices are installed on both sides of the main body of the ship, parallel to the hulls on both sides, and keep a distance from the hull , the installation situation is as follows image 3 As shown in the mark 4; each anti-wave impact plate 4-1, 4-2 is fixed with the shaft rod 4-3, 4-4, and the shaft rod 4-3, 4-4 pas...

Embodiment 3

[0036] The spring reset device 4-5 installed in the anti-wave device 4 on the ship according to the present invention is composed of a frame 4-5-1, a reset spring 4-5-3, a reset shaft rod 4-5-5, two Fixed nut 4-5-2, 4-5-4 is formed.

[0037] .The spring reset device 4-5 and the frame 4-5-1 in the anti-wave device 4 installed on the ship according to the present invention are fixed on the hull; both ends of the reset shaft 4-5-5 are provided with inner holes for It is inserted into the shaft rod 4-3, 4-4, the outer rings at both ends are covered with fixed nuts 4-5-2, 4-5-4, and the middle is covered with a return spring 4-5-3; one end of the spring 4-5-3 is connected to the The frame 4-5-1 is fixed, and the other end is fixed to one end of the reset shaft 4-5-5; the shafts 4-3, 4-4 fixed by the anti-wave impact plates 4-1, 4-2 pass through The hull is respectively inserted into the inner holes at both ends of the reset shaft rod 4-5-5 in the spring return device 4-5; the inse...

Abstract

Disclosed are an anti-wave catamaran and an anti-wave device mounted on the catamaran, belonging to the ship field. The invention is divided into three parts, namely, a hull shape structure, a wave passing device and an anti-wave device. The invention is characterized in that two hulls of the catamaran, the outer side of the bottom of each hull is a flat plate inclined to the inner side of the bottom, and the inner hull and the hull form a tip bottom, and both of the bows are provided with a triangular cone shaped wave device. The anti-wave device installed on the main body of the ship is composed of an anti-wave impact plate, a shaft rod and a spring return device. Wave crossing plates and anti-wave striking plates are on the waterline. The invention reduces the impact force of the surgewave through the tip bottom of the ship, decomposes the water surface wave impacting on the bow of the ship through the wave passing device, and transfers the impact force of the water surface wave impacting on the ship hull into the water on the other side of the ship hull through the wave resisting device; the displacement of the striking plate is restored by a spring retainer. The invention reduces the impact force of the surge wave and the surface wave on the catamaran, and enhances the stability of the ship hull in the surge area.

Description

technical field [0001] The invention relates to the field of ships, in particular to a wave-resistant catamaran. Background technique [0002] . Ships are often attacked by water waves from different directions during navigation, especially when sailing on the sea, they are often hit by surge waves and wind waves. Some ships with small loads such as warships, tourist boats, fishing boats, etc. Compared with the ship's own gravity, power and water buoyancy, the impact force it receives cannot be ignored, and it will have a serious impact on the ship's navigation, causing the ship's hull to vibrate, shake and become unstable, hinder the ship's forward movement, and sometimes even endanger the ship. safety. Therefore, a wave-resistant catamaran and an anti-wave device installed on the ship are designed to reduce the impact of external waves on the catamaran hull and improve the stability of the catamaran. Contents of the invention [0003] In order to solve the problem that...
