Abstract
The utility model discloses axial flow blower noise reduction pods.Including water conservancy diversion cover body, the combination of several groups exhaust vent is offered on the water conservancy diversion cover body, the combination of exhaust vent described in every group includes the exhaust vent that several circumferential directions are arranged on the water conservancy diversion cover body, and several annular guide rings are provided in the pod inner body wall, the annular guide ring be located at corresponding adjacent two groups described between exhaust vent combination.The utility model discharges air-out flow, step by step by rationally designing airflow channel on pod to reduce noise, pass through different overlapped in series combinations, and the air supplying distance and outlet air total pressure value of effectively increase blower reach noise-reducing purpose to adapt to different occasions.
Description
Technical field
The utility model relates to pod technical fields, especially axial flow blower noise reduction pod.
Background technique
Be commonly installed sound-absorbing porous material mounted in axial flow blower air side for the level of noise of blower, as sound-absorbing sponge,
Glass fibre etc..Cause volume big, cost is big, and erroneous for installation, appearance is unsightly.
Utility model content
The utility model aiming at the shortcomings in the prior art, provides axial flow blower noise reduction pod, by water conservancy diversion
Airflow channel is rationally designed on cover, discharges air-out flow step by step, to reduce noise, by different overlapped in series combinations,
And the air supplying distance and outlet air total pressure value of effectively increase blower reach noise-reducing purpose to adapt to different occasions.
In order to solve the above technical problems, the utility model is addressed by following technical proposals: axial flow blower noise reduction is led
Stream covers, including water conservancy diversion cover body, and the combination of several groups exhaust vent, the combination of exhaust vent described in every group are offered on the water conservancy diversion cover body
It include the exhaust vent that several circumferential directions are arranged on the water conservancy diversion cover body, and be arranged in the pod inner body wall
Have several annular guide rings, the annular guide ring be located at corresponding adjacent two groups described between exhaust vent combination.
In above scheme, it is preferred that the section of the annular guide ring is S-shaped.
In above scheme, it is preferred that exhaust vent combination includes the upper exhaust vent group being located above and underlying
Lower exhaust vent group, the upper exhaust vent group and the lower exhaust vent group include several circumferential settings in the water conservancy diversion cover body
On exhaust vent, and the exhaust vent of the upper exhaust vent group and the exhaust vent of the lower exhaust vent group are staggered.
The beneficial effects of the utility model are: the utility model on pod by rationally designing airflow channel, a step
Step release air-out flow, to reduce noise, by different overlapped in series combinations, and effectively increase blower air supplying distance and
Outlet air total pressure value reaches noise-reducing purpose to adapt to different occasions.
Detailed description of the invention
Fig. 1 is utility model diagram.
Fig. 2 is the utility model annular guide ring schematic diagram.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing: referring to Fig. 1 and Fig. 2,
Axial flow blower noise reduction pod, including water conservancy diversion cover body 1 offer the combination of several groups exhaust vent, institute on the water conservancy diversion cover body 1
Stating exhaust vent combination includes the upper exhaust vent group 2 and underlying lower exhaust vent group 3 being located above, the upper exhaust vent group 2
It include the exhaust vent that several circumferential directions are arranged on the water conservancy diversion cover body with the lower exhaust vent group 3, and the upper outlet air
The exhaust vent of hole group and the exhaust vent of the lower exhaust vent group are staggered.
Wherein, the diameter of the exhaust vent of upper exhaust vent group is greater than the diameter of the exhaust vent of lower exhaust vent group.
Several annular guide rings 4 are provided on 1 inner wall of water conservancy diversion cover body, the annular guide ring, which is located at, to be corresponded to
Adjacent two group described in exhaust vent combination between.
The section of the annular guide ring is S-shaped.After the annular guide ring for designing this kind of structure in water conservancy diversion cover body, energy
The release for enough promoting air-out flow orderly, to reduce noise.
Above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；Although referring to aforementioned reality
Example is applied the utility model is described in detail, those skilled in the art should understand that: it still can be to preceding
Technical solution documented by each embodiment is stated to modify or equivalent replacement of some of the technical features；And these
It modifies or replaces, the spirit and model of various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
It encloses.
