Abstract
The utility model discloses a kind of mute wind turbines, including babinet, it is equipped with motor fixed rack in the babinet, and is mounted with motor, motor connects impeller, the top of the box is equipped with air inlet, the air inlet is equipped with web plate, and the babinet side is equipped with air outlet, and the wall box on front side of the impeller is equipped with tubular muffling hole plate, a cavity is formed between tubular muffling hole plate and cabinet exterior, and acoustical cotton is filled in cavity.The utility model compared with prior art the advantages of be：The utility model solves the problems, such as that the lower noise of inside plants jet stream class wind turbine, the structure obtained by Entity measurement, muting function can reach significantly noise reduction purpose, and overall noise control range is between 75 decibels to 79 decibels.It is easy for installation due to complete machine body compact structure, ventilation in workshop can be met, cut and reach the range that human body can bear noise, improve in working environment, a good working environment is created in the protection to the auditory system of worker.
Description
Technical field
The utility model is related to wind turbine more particularly to a kind of mute wind turbines.
Background technology
The noise reduction mode of existing tunnel class wind turbine is that a columnar mute cover is respectively installed at the entrance of wind turbine,
Come play reduce noise purpose, but at air outlet air flowing mute cylinder between rub, will produce secondary noise, in addition
Sound will produce slow reflection in communication process, columnar structured to be unfavorable for irreflexive abatement.In addition heavy caliber wind turbine is quiet
The general length of sound cover is longer, and integral installation is oversized, is not suitable for factory or opposite narrow space uses.
Old-fashioned jet blower noise is excessive, 80 decibels born more than human ear, and the wind of general same specification wind turbine makes an uproar value all 2
120 decibels or so of rice.Being chronically exposed in high-decibel working environment can cause to damage to body, influence the sense of hearing system of human normal
System.
Utility model content
The utility model provides a kind of mute wind turbine to solve the above-mentioned deficiency of the prior art.
The above-mentioned purpose of the utility model is realized by technical solution below：A kind of mute wind turbine, it is characterised in that：
Including babinet, motor fixed rack is equipped in the babinet, and be mounted with motor, motor connects impeller, the babinet top
Portion is equipped with air inlet, and the air inlet is equipped with web plate, and the babinet side is equipped with air outlet, the wall box on front side of the impeller
Equipped with tubular muffling hole plate, a cavity is formed between tubular muffling hole plate and cabinet exterior, acoustical cotton is filled in cavity.
The babinet enhances the diffusing reflection consumption of interior noise for protecting internal structure, further decreases noise
Decibel.The babinet is in integrally rectangular parallelepiped structure, to the greatest extent so that noise is consumed during diffusing reflection, to rise
To mute effect.
The tubular muffling hole plate of the utility model had not only reduced the noise generated when air flowage friction, but also reduced motor and leaf
The noise generated when wheel operating.
The utility model compared with prior art the advantages of be：The utility model solves making an uproar for inside plants jet stream class wind turbine
Sound reduces problem, the structure obtained by Entity measurement, and muting function can reach significantly noise reduction purpose, overall noise control
Range processed is between 75 decibels to 79 decibels.It is easy for installation due to complete machine body compact structure, ventilation in workshop can be met, cut
Reach the range that human body can bear noise, improve in working environment, the protection to the auditory system of worker creates one well
Working environment.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the overlooking structure diagram of the utility model.
Fig. 3 is the internal structure schematic diagram of the utility model middle case.
Specific implementation mode
The utility model is described in further detail with reference to embodiment.
As shown in Figure 1, Figure 2 and Figure 3, a kind of mute wind turbine, it is characterised in that：Including babinet 1, it is equipped in the babinet 1
Motor fixed rack 2, and it is mounted with motor 3, motor 3 connects impeller 4, and 1 top of the babinet is equipped with air inlet 5, described
Air inlet 5 is equipped with web plate 6, and 1 side of the babinet is equipped with air outlet 7, and 1 side wall of babinet of 4 front side of the impeller disappears equipped with tubular
Grill 8 forms a cavity between 1 outer wall of tubular muffling hole plate 8 and babinet, acoustical cotton 9 is filled in cavity.
The babinet 1 enhances the diffusing reflection consumption of interior noise for protecting internal structure, further decreases noise
Decibel.The babinet is in integrally rectangular parallelepiped structure, to the greatest extent so that noise is consumed during diffusing reflection, to rise
To mute effect.
The tubular muffling hole plate 8 of the utility model had not only reduced the noise generated when air flowage friction, but reduce motor 3 with
The noise that impeller 4 generates when operating.
The above specific embodiments are only exemplary, is to preferably make skilled artisans appreciate that originally
Patent, be not to be construed as include to this patent range limitation；As long as appointing according to made by spirit disclosed in this patent
How with change or modification, the range that this patent includes is each fallen within.
Claims (2)
