Slot 106, guide plate 103 are fixedly connected by fixing groove 106 with support plate 102, and the spacing between the adjacent guide plate 103 after fixing
Equal, protective net 104 is sheathed on the outside of guide plate 103, and the bottom end of protective net 104 is bonded with the top surface of pedestal 101, protective net
104 top is connected and fixed with capping 105, and capping 105 is connect by screw with the top of support plate 102, and covers 105 bottom ends
Pyramidal structure be located at the middle top of the cylindrical space that support plate 102 and guide plate 103 are constituted, cover 105 ellipse
Top can reduce windage, less relative to spherical structure material, covers and is also provided with a circle rain at 105 cover rim
Curtain is used for rain cover.
One end of noise reduction box 3 be it is columnar structured, the other end is pyramidal structure, and noise reduction box 3 includes outer housing 301 and inner casing
Body 302, inner housing 302 are located at the inside of outer housing 301, and non-newtonian fluid is filled between outer housing 301 and inner housing 302
303, the outlet air end of the first blast pipe 2 and the arc surface of columnar structured part on noise reduction box 3 are tangent, the taper knot of noise reduction box 3
Structure end is connected with the second blast pipe 4, and the caliber section of the second blast pipe 4 is greater than the sum of the caliber section of multiple first blast pipes 2.
It wherein, is taper type structure in the middle part of the top surface of pedestal 101, support plate 102 is mounted on frustum on pedestal 101
The top of structure, the frustum structure on pedestal 101 are located at the lower inside of protective net 104, and the frustum structure on pedestal 101 can be with
The weld part of the bottom end of the pedestal 101 that makes and support plate 102 is in a high position, not perishable, protective net 104 can stop foreign matter with
And a degree of external force, it can also prevent foreign matter from entering in the first blast pipe 2.
Wherein, fire proof wind sluice 5 is installed on first blast pipe 2, the input terminal of fire proof wind sluice 5 and external control system it is defeated
Outlet is electrically connected, and safety is placed in first place, once occurring fire behavior in cabin, is cut off and is divulged information by fire proof wind sluice 5, reduces kindling
The oxygen content at place mitigates fire behavior.
Wherein, the end of columnar structured part is equipped with fire extinguisher canvas hose 6 on noise reduction box 3, is equipped on fire extinguisher canvas hose 6
Control valve 7, fire extinguisher canvas hose 6 and the water inlet end being located on 302 inner wall of inner housing are equipped with the hurricane globe of arcuate structure, if fire behavior compared with
The failure of big or fire proof wind sluice 5 can not start, then opening controlling valve 7, are passed through fire water by fire extinguisher canvas hose 6, to fire behavior into
Row is controlled and is put out.
Wherein, air cleaning system and muffler are installed on the second blast pipe 4, the sky of noise reduction is carried out by noise reduction box 3
Gas needs just be passed through cabin by air cleaning system, and arranges muffler in exhaust outlet or return air inlet, carries out further
Noise is eliminated, so that cabin is kept quite.
Wherein, pedestal 101, support plate 102, guide plate 103, protective net 104 and capping 105 are stainless steel material, energy
It is enough preferably to adapt to marine adverse circumstances, the service life of wind ball 1 is improved, and the material of stainless steel has better structure
Intensity, wind loading rating are more preferable.
Working principle: when in use, wind ball 1 is evenly arranged in the top in cabin, when sea wind blows over wind ball 1, wind ball 1
Oval top can reduce windage, to reduce the whole stress of wind ball 1, while the inverted V-shaped arrangement of guide plate 103, to blowing
The wind crossed guides so that wind is blown into the cylindrical space that support plate 102 and guide plate 103 are constituted, and in guide plate 103 and
Under the guidance for covering the pyramidal structure of 105 base portions setting, it is blown into the cylindrical space of support plate 102 and the composition of guide plate 103
Interior change of the wind rapidly enters noise reduction box 3 along the first blast pipe 2, since multiple wind balls 1 import high speed into noise reduction box 3
Air-flow, makes an uproar for the wind that reduction high-speed flow issues and high-speed flow drives the tank wall of noise reduction box 3 that the secondary of resonance generation occurs
Therefore the pollution of noise sets 302 double-layer structure of outer housing 301 and inner housing for noise reduction box 3, and in outer housing 301 and interior
Non-newtonian fluid 303 is filled between shell 302, since (such as DCLAN material: DCLAN molecule can be certainly for non-newtonian fluid 303
By activity, material is sufficiently flexible, comfortable.But when being impacted: DCLAN molecule can flock together rapidly, DCLAN material wink
Between change software strategy into software-hardware strategy, form a protection shell to keep out impact simultaneously, DCLAN intermolecular a large amount of " hydrogen bond " can temporarily " point
Open ", which consumes huge energy, so that impact force be dissipated rapidly.And after impact removes: DCLAN molecule affranchises
Activity, material become soft, comfort conditions again.Meanwhile DCLAN intermolecular a large amount of " hydrogen bond " moment " recombination ", DCLAN material are extensive
Reset condition is arrived again, and next Secondary Shocks are met in preparation.) exclusive characteristic, it can be good at the vibration for inhibiting inner housing 302, and
And wind is made an uproar by the transmitting of solid-liquid-solid, and low wind noise can greatly be dropped, due to the outlet air end and drop of the first blast pipe 2
Making an uproar on case 3, the arc surface of columnar structured part is tangent, and high-speed flow enters noise reduction box 3 and does centrifugal movement first, by dropping
The pyramidal structure part made an uproar on case 3 changes wind direction again, and into the second blast pipe 4, the caliber section of the second blast pipe 4 is greater than more
The sum of the caliber section of a first blast pipe 2, so that wind speed reduces, wind is made an uproar to be weakened again, is passing through air cleaning system and cloth
The muffler on exhaust outlet or return air inlet is set, so that cabin is able to maintain peace and quiet, in addition, being equipped on the first blast pipe 2
Fire proof wind sluice 5 preferably can control and put out fire behavior, the fire water of the end installation of columnar structured part on noise reduction box 3
Pipe 6, can be as spare, once fire behavior is larger or the failure of fire proof wind sluice 5 can not start, then opening controlling valve 7, enabling disappear
Guard tube 6, controls fire behavior and is put out.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
