Abstract
ERC bow net track detection vehicle Duct design method is related to bow net track detection vehicle Duct design technical field, is: air duct uses glass steel material, and air delivery duct main body is three-decker；Main air duct is divided by two groups of branch air ducts by transition air duct in observation tower position, using arc transition at the turning dog-ear in transition air duct, and transition air duct enter crook and protruding crook is respectively provided with deflector；Conductor's cubic and parlor add plate windward using outlet air form under top plate two sides at air outlet；Meeting room uses the implicit outlet air in top plate two sides, and air outlet is arranged between side top plate and middle top plate；Sensing chamber's air outlet is arranged in the lace of two sides, and Pierced Aluminum Plank is installed between lace and side wall as air outlet.Air duct of the invention uses the material of fire rating, and uses transition air duct in observation tower position, effectively reduces the loss of each air quantity；Air outlet uses outlet air and implicit outlet air form under top plate two sides, and is equipped with plate windward, effectively avoids cold air blow-through human body and influences comfort level.
Description
Technical field
The present invention relates to bow net track detection vehicle Duct design technical fields, and in particular to a kind of ERC bow net track detecting
Vehicle Duct design method.
Background technique
In order to provide comfortable the working environment, (letter of railroad, Ethiopia to the interior staff of bow net detection
Claiming ERC) bow net track detection vehicle is provided with air-conditioner set, interior each workplace is delivered the air to by ceiling duct, thus
Play the role of refrigeration, heating and cross air filtering, provides pleasant temperature, humidity and clean sky for operation within a vehicle personnel
Gas.
Since ERC bow net track detection vehicle roof is equipped with Contact Line Detection equipment, for convenient for the progress of roof detection device
Observation, vehicle middle part are equipped with observing tower.The setting of observing tower influences Duct design, is both needed in Duct design in observation tower position
It separates, merges back into main air duct form after crossing observing tower, air duct is affected to air quantity separately and in merging process, is easy to cause
Each air output deficiency below.Also, current outlet air form is the form of the downward blow-through of top plate, cold air blow-through body effect
Comfort level；Meanwhile interior individual parlor or workplace air duct air-out effect are bad, it is bad to also result in interior refrigeration effect, shadow
Ring comfort level.
Summary of the invention
It is easy to cause to solve existing ERC bow net track detection vehicle because air duct separates the structure merged at observing tower again
The technical issues of outlet air form of each air output deficiency and the downward blow-through of top plate seriously affects human comfort, the present invention
A kind of ERC bow net track detection vehicle Duct design method is provided.
The technical solution adopted for solving the technical problem of the present invention is as follows:
ERC bow net track detection vehicle Duct design method comprising as follows:
1) selection of duct materials
Air duct uses glass steel material, and air delivery duct main body is three-decker, and overall thickness 6mm, upper and lower layer structure be
The phenol aldehyde glass steel construction of 1.5mm thickness, interlayer structure are the foaming structure of 3mm thickness；Branch air duct uses the 4mm without foaming structure
Thick phenolic fiberglass reinforced plastics；
2) integrally-built design
Two section main air ducts are set before the observing tower in portion altogether in the car, pass through transition air duct for main air duct in observation tower position
It is divided into two groups of branch air ducts, left side of car and right side of car respectively set one group of branch air duct；Arc transition is used at the turning dog-ear in transition air duct,
And transition air duct enter crook and protruding crook is respectively provided with deflector；
3) design of outlet air form
Interior conductor's cubic and parlor are all made of outlet air form under top plate two sides, and plate windward is added at air outlet, with
Weaken wind speed；Meeting room uses the implicit outlet air in top plate two sides, and air outlet is arranged between side top plate and middle top plate；Sensing chamber's outlet air
Mouth is arranged in the lace of two sides, and Pierced Aluminum Plank is installed between lace and side wall as air outlet.
The beneficial effects of the present invention are: Duct design uses the material of fire rating, and adopted at by observation tower position
With transition air channel structure, the loss of each air quantity below can be effectively reduced；Air outlet is using outlet air under top plate two sides and implicitly
Outlet air form, and it is equipped with plate windward, it effectively avoids cold air blow-through human body and influences comfort level.
Specific embodiment
ERC bow net track detection vehicle Duct design method of the invention is as follows:
1) selection of duct materials
Air duct uses glass steel material, and air delivery duct main body is three-decker, and overall thickness 6mm, upper and lower layer structure be
The phenol aldehyde glass steel construction of 1.5mm thickness, interlayer structure are the foaming structure of 3mm thickness, enhance thermal insulation.Branch air duct is using no hair
The phenolic fiberglass reinforced plastics of the 4mm thickness of bubble structure, the limits of harmful substances of material meet TB/T3139 requirement, and fire protecting performance meets TB/
The extremely difficult combustion grade requirement of T3138.
2) integrally-built design
Two section main air ducts are set before the observing tower in portion altogether in the car, pass through transition air duct for main air duct in observation tower position
It is divided into two groups of branch air ducts, left side of car and right side of car respectively set one group of branch air duct；Main air duct section is according to air-conditioner set air output and sets
Wind speed requires to be designed inside air duct in meter standard, and branch air duct is in the case where meeting air quantity demand, in conjunction with roof structure
And roof space is designed；At the turning dog-ear in transition air duct use arc transition, and transition air duct enter crook and go out
Crook is respectively provided with deflector, guarantees that air-supply passes through according to optimal path as far as possible, reduces wind loss.
3) design of outlet air form
Interior conductor's cubic and parlor are all made of outlet air form under top plate two sides, and plate windward is added at air outlet, with
Weaken wind speed, effectively avoids blow-through upper berth；Meeting room uses the implicit outlet air in top plate two sides, and air outlet is arranged in side top plate and middle top
Between plate；Sensing chamber's air outlet is arranged in the lace of two sides, and Pierced Aluminum Plank is installed between lace and side wall as air outlet, meeting
Room and sensing chamber's air-out direction avoid blow-through staff.
