Abstract
The present invention relates to a kind of communication base station ventilation duct rain insensitive devices, comprising: streamlined rain cover, connecting tube and ventilation opening；The connecting tube is drenched with rain part for connecting ventilation duct, and the streamlined rain cover is fixedly connected on upper end of connecting tube, and the ventilation opening is arranged in connecting tube；The present invention reduces the influence that the installation fixed structure to ventilation duct is reduced because of the setting additional wind load of rain cover bring by setting streamlined for rain cover.
Description
Technical field
The present invention relates to rain insensitive device field more particularly to a kind of communication base station ventilation duct rain insensitive devices.
Background technique
To prevent rainwater and sundries from flowing backward in the outdoor ventilation pipe of communication base station, existing, common rain insensitive device is more
For at the top of ventilation duct install additional umbrella shape rain cover, but due to ventilation duct be guarantee ventilation effect, top generally away from ground farther out,
Existing umbrella shape rain cover is to guarantee rain-proof, dust-proof effect, and rain cover design is relatively large in diameter, to retain airspace, rain-proof
Cover lower part is only fixed by the bracket at the top of ventilation duct, and is mounted on high aerial rain cover because area is larger, by upper-level winds
Influence is formed by wind load resistance on it and also necessarily increases.
Existing communication base station rain insensitive device has a following defect: umbrella shape rain cover because the wind load resistance carried is larger,
It is fixed to the installation of entire ventilation duct to constitute larger impact；Because the connection mounting structure of rain cover and ventilation duct is relatively simple, by
Expose to the sun and rain and the influence of a variety of unfavorable factors such as corrosion for a long time, be easier to be formed connecting bracket fracture and rain cover fall it is equal seriously
Security risk.
Summary of the invention
The purpose of the present invention is what is be achieved through the following technical solutions.
A kind of communication base station ventilation duct rain insensitive device, comprising: streamlined rain cover, connecting tube and ventilation opening；The connection
Pipe is drenched with rain part for connecting ventilation duct, and the streamlined rain cover is fixedly connected on upper end of connecting tube, the ventilation opening setting
In connecting tube.
Further, streamlined rain cover and connecting tube are axially provided on ventilation duct multiple respectively.
Further, ventilation opening is provided with the backstop for stopping sundries.
The present invention has the advantages that the present invention is reduced by setting streamlined for rain cover because of setting rain cover
The additional wind load of bring reduces the influence of the installation fixed structure to ventilation duct.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Attached drawing 1 shows a kind of structural representation of communication base station ventilation duct rain insensitive device of embodiment according to the present invention
Figure.
Appended drawing reference: 1, streamlined rain cover；2, connecting tube；3, ventilation opening；4, backstop.
Specific embodiment
In the following detailed description, many details are proposed, in order to complete understanding of the present invention.But
It will be apparent to those skilled in the art that the present invention can not need some details in these details
In the case of implement.Below to the description of embodiment just for the sake of provided by showing example of the invention to it is of the invention more
Understand well.
Below in conjunction with attached drawing, the technical solution of the embodiment of the present invention is described.
As shown in Figure 1, the present invention provides a kind of communication base station ventilation duct rain insensitive device, comprising: streamlined rain cover 1 connects
Adapter tube 2 and ventilation opening 3；The connecting tube 2 is drenched with rain part for connecting ventilation duct, and the streamlined rain cover 1 is fixedly connected on
2 upper end of connecting tube, the ventilation opening 3 are arranged in connecting tube 2.
According to an aspect of the present invention, streamlined rain cover 1 and connecting tube 2 are axially provided on ventilation duct more respectively
It is a.
According to an aspect of the present invention, ventilation opening 3 is provided with the backstop 4 for stopping sundries.
The present invention is reduced by setting streamlined for rain cover because of the setting additional wind load of rain cover bring, drop
The influence of the low installation fixed structure to ventilation duct.
The present invention is not limited to examples detailed above, in claims of the present invention limited range, art technology
The various deformations or amendments that personnel can make without creative work are protected by this patent.
