Embodiment is modified.Therefore, attached drawing and description are regarded as illustrative in nature, rather than the protection for limiting claim
Range.
As shown in Figures 1 to 4, conducive to the ship Ventilator device of noise reduction, including upper shell 1 and lower shell 2, it is described on
Cylinder 1 and the lower shell 2 are rotatably connected by bearing 3, and air inlet cylinder 4, the upper cylinder are provided on the upper shell 1
The tail portion for being located at the air inlet cylinder 4 on body 1, which extends back, is provided with strut 5, and the end of the strut 5 is fixedly installed with wind gathering cover
6, it is provided with chimney fan 7 on the lower shell 2, offers several length respectively on the barrel of the upper shell 1 and the lower shell 2
Slot is movably installed with an acoustical panel 8 in each long slot hole respectively;When the air inlet direction of ventilator down the wind when,
Wind blows the wind gathering cover 6, and the resistance of generation rotates the upper shell 1 around the bearing 3, makes the air inlet cylinder 4 always
Down the wind, air external in this way is very easy to enter inside cabin by ventilator, when the air inlet direction of ventilator against
Wind direction or inclination are when blowing to the air inlet cylinder 4, under drag effect of the wind gathering cover 6 to wind, drive the upper shell 1 around
The bearing 3 rotate, rotate to the air inlet cylinder 4 down the wind, external air again can very easily process be divulged information
Cylinder enter cabin inside, therefore, the wind gathering cover 6 plays the role of wind vane, make the air inlet cylinder 4 always with wind direction one
It causes, also assures ventilation effect in the case where not using blower, avoid blower bring noise, and due to the upper shell
1 and the lower shell 2 barrel on offer several long slot holes respectively, be movably installed with one respectively in each long slot hole
The acoustical panel 8, the acoustical panel 8 can prevent sound transmission and air-flow allowed to pass through, and be to eliminate air power noise
Important measures can according to need the number for selecting the acoustical panel 8 to install since the acoustical panel 8 is activity installation
Amount and model, can the degree that reduces of effective control noise.
As depicted in figs. 1 and 2, the upper shell 1 and the lower shell 2 are " L " type tube body, the upper shell 1 and institute
It is cylinder that lower shell 2, which is stated, by one end that the bearing 3 links together, and the air inlet cylinder 4 and the chimney fan 7 are respectively side
Cylinder.The lower end of the upper shell 1 and the upper end of the lower shell 2 are the cylinder, therefore the two can pass through the bearing 3
It is rotatably connected, and rotates very flexibly, convenient for being rotated in time with wind direction, the upper end of the upper shell 1 and institute
The lower end for stating lower shell 2 is respectively the square tube, convenient for the installation of the acoustical panel 8, the shape of the acoustical panel 8 and the side
The inside dimension of cylinder is adapted.
As shown in Figures 2 and 3, the acoustical panel 8 includes the plate body 9 positioned at the wall inner portion, the two sides of the plate body 9
It is fixedly installed with noise reduction rubber slab 10 respectively, further includes the knob portion being wholely set outside the barrel with the plate body 9
11.Resistive muffler mainly reduces noise using sound-absorbing porous material.Sound-absorbing material is fixed in airflow channel
It is arranged in the duct on wall or according to certain way, just constitutes resistive muffler.When sound wave enters resistive muffler, one
Divide sound that can rub in the hole of porous material and be converted to thermal energy consumption and dissipate, makes to weaken by the sound wave of muffler.It is described to disappear
Soundboard 8 just belongs to resistive muffler, and the overall dimensions of the acoustical panel 8 are adapted with the barrel, and the acoustical panel 8 can lead to
The long slot hole that the knob portion 11 pulls out and is packed on the barrel is crossed, therefore when erasure effect is undesirable, Ke Yishi
When the quantity that increases the acoustical panel 8 improves erasure effect, sound reaches under the blocking of the acoustical panel 8 in layer
To the effect of good noise reduction, the noise reduction rubber slab 10 not only with noise reduction but also can have certain elasticity, in this way can be with
Fix the acoustical panel 8 in the long slot hole stronger, and the better tightness with the long slot hole.
As shown in Figure 3 and Figure 4, the acoustical panel 8 can be the vertical barrel to insert, and be also possible to tilt certain angle
Degree selects suitable setting angle according to the actual situation to insert to ensure good erasure effect.
As shown in Figure 1 to Figure 3, several bloops 12 are provided on the acoustical panel 8.Can wherein a part described in disappear
The bloop 12 is provided on soundboard 8.The proof gold metal thin plate that the acoustical panel 8 can be less than 1mm using thickness makes, thin
It is less than the bit bore of 1mm on plate with aperture, punching rate is 1% one 3%, the chamber for selecting different punching rates different with plate thickness
It is deep, so that it may which that the spectral performance for controlling muffler makes it obtain good erasure effect in the frequency range of needs.Work as use
When the acoustical panel 8 with the bloop 12, be between the acoustical panel 8 and the barrel it is gapless, air passes through
The bloop 12 circulates;But when using the acoustical panel 8 without the bloop 12, the acoustical panel 8
The gap for thering is gas to circulate between the barrel.
As depicted in figs. 1 and 2, the wind gathering cover 6 is plastics umbrella wind gathering cover.The wind gathering cover 6 is similar in life often
The wind sleeve seen.It is preferably made of light-weight water-proof cloth, there is flexibility ratio high point, threshold wind velocity is small for revolution, high reliablity, makes
With the advantage that the service life is long, the wind gathering cover 6 can drive the upper shell 1 under described according to wind direction adjust automatically direction
Cylinder 2 rotates, and is that direction is grasped in the rotation of the upper shell 1.
The utility model does not illustrate the utility model preferably in the oral area of the air inlet cylinder 4 withouyt blower
The air inlet cylinder 4 at cannot install blower additional, blower can also be installed additional according to the actual situation, then pass through the acoustical panel 8
Carry out noise reduction.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
