Specific embodiment
With reference to the accompanying drawings and examples, the specific embodiment of the present invention is described in further detail.Hereinafter implement
Example is for illustrating the present invention, but can not be used for limiting the scope of the present invention.
The construct noise produced because of vibration in running is pushed away for effectively reducing extra large work stem side, by analysis, meter
Calculate and model test, the present invention increases the setting height(from bottom) that bow side pushes away, make bow side the supporting construction of connection be pushed away on obsolete vessel type basis
Life be remarkably reinforced, also bow side push away flow inlet increase bell-mouth structure of air, while bow side push away with altitude above deck direction
Increase annular connection structure, cancel bow side and push away place rib position deck opening, make deck cross member structure keep continuous.
The structure that the extra large work stem side with decrease of noise functions in the embodiment of the present invention pushes away as shown in Figure 1 to Figure 3, the bow side
Push away 1 top and be connected on deck 100 by connecting supporter 2, connection supporter 2 includes lateral connection frame 3 and multiple longitudinal directions
Connection bracing frame 4, multiple longitudinally connected bracing frames 4 are arranged along the width parallel interval that bow side pushes away 1, and with size successively
The arrangement mode distribution successively decreased.Lateral connection frame 3 is vertical with multiple longitudinally connected bracing frames 4 to be connected, and the horizontal stroke of lateral connection frame 3
Successively decrease successively to form trapezoidal shape to size, lateral connection frame 3 and multiple longitudinally connected bracing frames 4 are integrally formed the energy of reinforcement
The connection supporting frame of vibrating noise is reduced enough.The supporting construction of connection supporter 2 is remarkably reinforced so that bow side pushes away 1 energy
