Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments, is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-5, a kind of novel environment friendly blimp, including pedestal 1 are please referred to, the lower outside of pedestal 1 offers outer respectively
The inside of portion's air inlet 101 and exhaust outlet 102, external air inlet 101 and exhaust outlet 102 is fixedly connected to Air Filter 103, prevents
Dirt net 103 prevents dust from entering the inside of damping layer 3, so that inner air be hindered to transmit.The upper side of pedestal 1 slidably connects
Shell 2, the inside of shell 2 are fixedly connected with damping layer 3, and it is a cylindrical tube shape that damping layer 3 is whole and wall inner portion is opened
Equipped with annular groove, because the best approach for eliminating noise is exactly to seal, but the heat due to needing to generate Working mechanism 11
It radiates, so the structure of the shape cooperation sound absorbing layer 4 of damping layer 3 is the main point of this innovation, on the inside of damping layer 3
Side position offers the first inside air outlet 301 and the second inside air inlet 303, the outer lower side position point of damping layer 3 respectively
The second inside air inlet 303 and the second inside air outlet 304 are not offered, because this secondary design increases noise in communication process
In distance, be on the one hand conducive to be absorbed by sound absorbing layer 4, on the one hand as the increase amplitude of propagation distance constantly reduces, thus
Weaken the intensity of noise.Damping layer 3 is internally provided with sound absorbing layer 4, and the inside of sound absorbing layer 4 offers annular air channel 401, ring
The inside of shape ventilating duct 401 is fixedly installed with reflecting plate 402, and annular air channel 401 greatly increases the distance of noise transmission,
Reflecting plate 402 is effectively rebounded the direction of propagation of partial noise to sound absorbing layer 4, to improve absorption of the sound absorbing layer 4 to noise.
The inside upper left side of damping layer 3 is fixedly connected with fan 5, and fan 5 selects silent fan or mute turbofan.
The upper end of pedestal 1 is fixedly connected with stabilizer blade 6, and the upper end of stabilizer blade 6 is fixedly connected with rack 7, the inside of rack 7
Sliding slot 701 is offered, sliding slot 701 facilitates the movement of fixed frame 9.The outside of stabilizer blade 6 is provided with the first spring 8, rack 7 it is interior
Portion both ends slidably connect fixed frame 9, and the shape of fixed frame 9 is half drum, and the fixed frame 9 of half work shape can save space
Utilization.The inboard of fixed frame 9 is fixedly connected to stripper plate 10, and the bosom position of stripper plate 10 offers rectangular channel
1001, the bosom position of stripper plate 10 and pressing plate 1002 is slidably connected in rectangular channel 1001,1002 He of pressing plate
Stripper plate 10 is fixedly connected with second spring 1003, this structure is to be carried out by the way that multiple damping springs are arranged to Working mechanism 11
The weakening of vibration, this is the most direct effective method of reduction vibration source noise, but but for the generation of the noise inside machine
It can not change, because this is the problem of machine itself designs.Between two stripper plates 10 and it is fixedly mounted on rack 7 and is provided with
Working mechanism 11.
Working principle: the novel sound insulation cover, at work by driving fan 5, fan 5 drives outside air from Air Filter
After 103 dedustings, enters in the annular air channel 401 of inside setting of damping layer 3, first pass through 3 weakened part noise of damping layer
Sound wave kinetic energy, then further noise is absorbed by sound absorbing layer 4, it is further anti-by what is be arranged in sound absorbing layer 4
It penetrates plate 402 the partial noise direction of propagation is rebounded onto sound absorbing layer 4, and with the increase of propagation distance, the vibration of noise transmission
Width reduces, and due to the setting of longer annular air channel 401 and the setting of multiple reflecting plates 402, can fully ensure that resistance in this way
The absorption of Buddhist nun's layer 3 and sound absorbing layer 4 to noise, the setting direction of inclined reflection plate 402 has reflecting effect to noise, so inclination
