Further, raft frame of the present invention is shaped as I-shaped, and its side and lower surface are provided with lightening hole.
Raft frame of the present invention, the installation for acoustic hood and electromechanical equipment provide platform, realize the isolating technique of equipment；Sound insulation
Cover, has good sound insulation property, helps to improve work and the living environment of ship person；Acoustic shell couples pattern with the integrated of raft frame,
Realize that the vibration of plant equipment, airborne noise are isolated by integrated design, reduce space requirement and weight load to totality,
Reduce totality involves engineering, has good sealing property, sound insulation property, preferably meets the use, maintenance, behaviour of ship person
The convenience requirement make, open and inspect, reassembled, good solution route is provided with the application of airborne noise noise countermeasure for ship, can
The airborne noise control that small space is closed for ship provides effective application measure.
Beneficial effect
First, the present invention has good vibration isolation and sound insulation function integration, and reduce vibration and noise reducing work takes effect.Vibration isolation
Raft frame is the mounting platform of acoustic hood, and vibration isolation raft frame upper surface provides good bottom lock for acoustic hood, further lifting
The defening effect of acoustic hood；Acoustic hood provides mass effect for vibration isolation raft frame simultaneously, the lighting of raft frame can be achieved, simultaneously
It is also beneficial to the raising of vibration isolating effect.
Second, the present invention has preferable spatially integrate property.Acoustic hood is taken root on raft frame, and is designed with raft frame guarantor type, is kept away
Exempt from still further to want space to totality, to totally bring to involve engineering few.
3rd, the present invention has good dismounting maintenance function.It is connected and fixed between acoustic hood piecemeal by snap-type；
Acoustic hood is consolidated by the connecting rack and connection transition boss of " L+U " type structure with raft frame to be coupled, and is using less screw
It can meet to fix requirement.Therefore sound proof box convenient disassembly, meets ship working service requirement.
4th, it is an advantage of the invention that vibration isolation and sound insulation function is integrated, compact-sized, convenient disassembly, reliability are high, ring
It border strong adaptability, can effectively suppress vibration and the airborne noise transmission of ship equipment, be ship vibration equipment Noise measarement, air
The popularization and application of noise acoustic hood provide good solution route.
