Abstract
The utility model discloses a roof is combination formula silencing cap for fan belongs to fan and ventilation system engineering technical field, include the cover body that covers the roof fan, the cover body is including tilting noise elimination roof and lateral wall, in the lateral wall, install the rain -proof tripe of eliminating the noise on the wall body more than relative set up a pair of or a pair of, install the access door on wall body in the surplus wall body or the more than one wall body. The utility model relates to a roof is combination formula silencing cap for fan not only can obviously reduce roof fan noise, can promote roof fan rain -proof moreover, prevent wind husky ability.
Description
Technical field
The utility model discloses a kind of roof ventilator Combined type muffling cover, belongs to blower fan and ventilation system field of engineering technology.
Background technique
Along with the continuous propelling that continuous expansion and the urban modernization of production scale of enterprise are built, the application of roof ventilator in engineering is in rising trend, is widely used in all kinds of civil building such as market, hotel, working shop of enterprise.
In the area that the population such as residential belt, commercial district is relatively intensive, higher to the noise requirements of roof ventilator.
Although roof ventilator self can by optimal design that is pneumatic and structure, the noise reduction object acquired a certain degree, for some places that noise requirements is higher, silencing equipment must be installed to meet the requirement of user to Noise measarement.
Model utility content
The purpose of this utility model is to provide a kind ofly not only obviously can reduce roof ventilator noise, but also can promote that roof ventilator is rainproof, the roof ventilator Combined type muffling cover of sand-proof ability.
For achieving the above object, the technological scheme that the utility model adopts is:
A kind of roof ventilator Combined type muffling cover, comprise the cover body covered by roof ventilator, described cover body comprises tilting noise elimination top board and sidewall; In sidewall, a pair or more of wall body be oppositely arranged is provided with noise elimination stormproof louvre, a wall body in residue wall body or more than one wall body are provided with access door.
As the further setting of such scheme, the sidewall cross-sectional of described cover body is square (shape that namely sidewall surrounds is square), wherein two wall bodies be oppositely arranged all are provided with noise elimination stormproof louvre, two other wall body be oppositely arranged all is provided with access door.This vibrational power flow, structure is simple, cost is low.
Described tilting noise elimination top board is by the wall body being provided with noise elimination stormproof louvre, and the wall body direction being provided with noise elimination stormproof louvre to another tilts.
A kind of roof ventilator Combined type muffling cover of the utility model, adopts the design of piecemeal combined type, comprises tilting noise elimination top board, noise elimination stormproof louvre, access door.Roof ventilator runs the noise produced, major part absorb by the utility model, therefore to cover body external environmemt propagate noise significantly reduce.Meanwhile, the design of tilting noise elimination top board, noise elimination stormproof louvre, can also effectively intercept rainwater and directly contact with roof ventilator with dust storm, obviously promotes that roof ventilator is rainproof, the ability of sand-proof etc.; The design of access door, facilitates roof ventilator Maintenance and Repair.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of roof ventilator Combined type muffling cover of the utility model, comprise the cover body covered by roof ventilator 2, cover body comprises tilting noise elimination top board 3 and sidewall; In sidewall, a pair or more of wall body be oppositely arranged is provided with noise elimination stormproof louvre 1, a wall body in residue wall body or more than one wall body are provided with access door 4.
As preferably, in the present embodiment, the sidewall cross-sectional of cover body is square (namely sidewall is made up of four orthogonal wall bodies), wherein two wall bodies be oppositely arranged all is provided with noise elimination stormproof louvre 1, two other wall body be oppositely arranged all is provided with access door 4.
Tilting noise elimination top board 3 is by the wall body being provided with noise elimination stormproof louvre 1, and the wall body direction being provided with noise elimination stormproof louvre 1 to another tilts.
Roof ventilator 2 runs the noise produced, and is partially absorbed by tilting noise elimination top board 3, noise elimination stormproof louvre 1, access door 4, and the noise propagated to cover body external environmemt significantly reduces.Meanwhile, the inclined design of tilting noise elimination top board 3, noise elimination stormproof louvre 1 waterproof design obliquely, effectively can intercept rainwater and directly contact with roof ventilator 2 with dust storm, obviously promotes rainproof, the sand-proof ability of roof ventilator 2.In addition, before and after access door 4, two fan designs, facilitate roof ventilator 2 Maintenance and Repair.
Above-described embodiment only illustrates inventive concept of the present utility model for explaining, but not the restriction to the utility model rights protection, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should fall into protection domain of the present utility model.
Claims (3)
