Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] refer to figure 1 , 3 , the bionic wave control board A1 and the bionic wave control board B 2 are arranged in a staggered manner, and are respectively connected to the rotating shaft 5 through two connecting pieces 4 . The rotating shaft can be driven by a motor and a transmission mechanism. Whole bionic wave suppression device is installed in stern 6. The bionic wave breaker has a concave-convex trailing edge 3 .

[0022] refer to figure 2 , 4 , 5. When the ship's speed and the wind, waves, current environment, etc. change, the angle of the bionic wave suppressor can be adjusted by rotating the rotating shaft 5 to achieve the best energy-saving effect.

[0023] refer to Figure 6 , when the ship does not need to use the breaker board, it can be retracted inside the ship, so that no additional resistance will be added.

[0024] refer to Fig...

Abstract

The invention belongs to the technical field of ships, and particularly relates to a bionic wave suppression device. The bionic wave suppression device mainly comprises a bionic wave suppression plate, a rotating shaft and a flow guiding channel and the like. The bionic wave suppression plate is provided with a tail edge in concave-convex shape, and the bottom is provided with the flow guiding channel. Through rotating the rotating shaft, an angle of the bionic wave suppression plate can be adjusted, and the optimal effect is achieved. While a ship does not need to use the wave suppression device, the wave suppression device can be taken back to the interior of the ship, so additional resistance cannot be increased. The bionic wave suppression device is an energy-saving device suitable forhigh-speed ship and naval vessel, and is an energy-saving accessory body capable of improving ship hydrodynamic performance, capable of increasing a virtual length of a ship body, improving a wake flow, and reducing wave-making resistance, and has functions of adjusting naval vessel sailing pitch and improving sailing resistance.

Description

technical field [0001] The invention belongs to the technical field of ships, and in particular relates to a bionic wave suppression device suitable for high-speed ships. Background technique [0002] When the ship is sailing in waves, the violent pitching will cause the propeller to come out of the water and cause speeding phenomenon, and the bottom attack caused by the "dolphin movement" is likely to cause material fatigue damage and cause structural failure, resulting in mechanical and instrument failures and even ship crashes. accident. The wave suppressing device is an appendage to improve the hydrodynamic performance of the ship, and has the functions of adjusting the pitch of the boat and improving the sailing resistance. It can increase the imaginary length of the hull, improve the wake and reduce the wave-making resistance. From the perspective of hydrodynamics, the wave suppressing device can change the distribution of hydrodynamic lift on the bottom of the ship....
