Description
Technical field
The present invention relates to a kind of ventilation unit, and in particular to a kind of antenna house top portion ventilation device, belong to radio communication neck
Domain.
Background technology
The dress that antenna house top portion ventilation device is to realize inside antenna house ventilation function and the external world between and designs
Put, the device is generally mounted at the top of antenna house, while requiring that the device possesses anti-corrosion, rain-proof, Defend salt fog, resistance to certain wind load
The characteristic such as little with electromagnetic wave influence.Existing antenna house ventilation unit is made up of outside blast cap and inner side air duct two parts, outer crosswind
Cap and inner side air duct are connected with the tapping flange of antenna house top unit plate using outward flange, in outer crosswind cap circumference
There is the vent window with fly net in face, and between outside blast cap flange and antenna house top unit plate, only connection is not sealed, be easy to from
The rainwater that vent window is entered is discharged, and seals, prevent the entrance of rainwater between inner side air duct flange and antenna house top unit plate,
On the air duct of inner side, the height on edge is generally greater than along about 0.2m on vent window, forms rain blocking wall, between outside blast cap and inner side air duct
Cavity defines ventilating duct, and the ventilating duct is communicated with the perforate of antenna house top unit plate, so realizes the work(of ventilation
Can be (see accompanying drawing 1).
There are the following problems for existing ventilation unit：1. existing ventilation unit is divulged information and rain-proof to reach in structure design
Requirement, make outside blast cap and inner side air duct height and be relatively large in diameter, (height of outside blast cap be 1m, a diameter of 1.5m；Interior
Crosswind cylinder is highly 0.75m, a diameter of 1m) deeper die cavity fiber lay down on mould when highly increasing the product offhand
Put the difficulty with resin dipping, operating efficiency is relatively low and quality that have impact on product；2. as outside blast cap is relatively large in diameter, one is made
A little antenna house top unit plates compared with small area are difficult to install the ventilation unit, and the versatility of the ventilation unit is poor；3. existing
There is ventilation unit to need first to install inner side air duct when mounted and outside blast cap is installed again, connecting bolt needs antenna house inner side and outer side
Two people operate simultaneously and are fastened, less efficient and later maintenance is difficult；4. two weeks of outside blast cap and inner side air duct are connected
Connecting bolt need carry out inside and outside bolt and hole loaded down with trivial details sealing, often occur herein poorly sealed and leak phenomenon；
5. as vent window is opened on the blast cap of outside, beam wind is directly blown in blast cap, and in the blast cap of outside, intake is instantaneously more than row
Air quantity, makes air pressure increase in the blast cap of outside, is unfavorable for the exclusion of air in antenna house；During damp and hot weather, can not have in antenna house
Imitated carries out exhaust ventilation, and the heat that radar antenna radiant power is produced cannot be excluded in time, have impact on radar antenna equipment
Performance, common solution are to increase air blast in antenna house bottom to carry out active forced ventilation.6. existing ventilation is filled
Although the version that puts can stop the raindrop of vertical landing, and most rainfalls are accompanied by beam wind, and rainwater is directly drenched logical
On air regulator, cross the rain blocking wall that outside blast cap and inner side air duct are formed with the wind, rainwater is entered into from top unit plate perforate
In antenna house, the approach axis of (see accompanying drawing 1) rainwater and path can be entered for straight line, rainwater is directly dropped in and are installed on lower section
Radar antenna on；7. during extreme weather, vent window cannot be closed, and cause salt fog to pour in and be splashed in antenna house with rainwater.Its
In 4. 5. 6. 7. produced problem in bar, have impact on the overall performance of antenna house, hamper and be installed on radar day in antenna house
The normal work of line.
Content of the invention
The present invention is the poor and various antenna house assembling of the low end product quality of the existing antenna house ventilation unit manufacture efficiency of solution
Poor universality, later maintenance are difficult, and gravity-flow ventilation ventilation effect is poor, and roof leaking phenomenon often occurs, and affect radar antenna to use
The problem of performance, and then propose a kind of antenna house top portion ventilation device.
The present invention is adopted the technical scheme that for solving the above problems：
The antenna house ventilation unit of present invention design mainly includes mushroom-shaped upper cover body, base and returning face plate, on mushroom-shaped
On the base, vent window is arranged on the lateral wall of the halfpace of base bottom hollow out lid spiral-lock, and returning face plate is installed on logical
On air regulator.Mushroom-shaped upper cover body edge is provided with the adpting flange for stretching out, and mushroom-shaped upper cover body is by adpting flange and annular
Outer is connected, and the bottom surface of hollow cylinder is provided with the adpting flange for extending internally for through hole, the adpting flange and antenna house
Flange connection at top unit plate opening.Cavity between mushroom-shaped upper cover body and base defines ventilating duct, the ventilating duct with
The perforate of antenna house top unit plate is communicated, and so realizes that the function of ventilation, returning face plate can achieve the envelope to vent window
Close, so realize that cut-off rainwater and salt fog are to the entrance in antenna house during bad weather.
The invention has the beneficial effects as follows：Manufacture material of the present invention adopts Matrix Fiberglass Composite Explosive, makes the present invention
Have that light weight intensity is high, corrosion resistant characteristic, while the material has preferable permeability to electromagnetic wave.The invention provides one
The antenna house ventilation unit that design size is easy to technological forming is planted, the dress of each model antenna house top unit plate can be met
Match somebody with somebody, versatility is good；When installing the ventilation unit, installation personnel only need to be carried on the inside of antenna house, one completes the fastening work of bolt
High operating efficiency and operate safer；Form construction design at mushroom-shaped structure design, vent window opening, effectively
The entrance for preventing rainwater, while to the ventilation volume in antenna house when increasing gravity-flow ventilation, reducing force ventilated energy
Source consumes；The design of turnover baffle plates on vent window, can effectively prevent pouring in for salt fog in inclement weather and splashing for rainwater
Enter.The design and application of the new antenna cover ventilation unit, efficiently solves the series of problems that original ventilation unit is present,
The overall performance of antenna house is further improve, and the radar antenna for installing inside antenna house provides preferably protection.
