Abstract
The utility model relates to a natural ventilator on top of railway carriage, comprising a guide duct; wherein, a flange is arranged on the outer wall of the guide duct, reinforcing plates are positioned on the outer wall of the guide duct and on the flange, a ring-disc is arranged on the reinforcing plate, a threaded sleeve is connected with the upper part of the ring-disc near the external diameter part, an intracavity welding part is formed by the guide duct, the flange, the reinforcing plate, the ring-disc and the threaded sleeve; an outer welding part is formed by a roof plate, an outer ring and an inner ring, the outer ring and the inner ring are connected with the lower part of the roof plate, four vents are arranged between the inner ring and the outer ring on the roof plate evenly, the internal, external welding parts are connected as a body. The utility model is characterized in that: the guide duct is through the roof plate and connected with the grid on the interior decorative roof plate inside the carriage, the ring-disc is arranged on the reinforcing plate, the outer ring and the inner ring are connected with the lower part of the roof plate, and four vents are arranged between the inner ring and the outer ring on the roof plate evenly, realizing the aim of ventilation, rain protection, convenience in disassembly and maintenance; a weather resisting steel plate with a thickness of 3mm is selected as the main material of carriage roof plate natural ventilator, a silicone rubber is selected as a sealing gasket material, and both materials are suitable for the climate condition in Bangladesh.
Description
Technical field:
The utility model relates to a kind of drafting apparatus, especially relates to a kind of inside and outside wind, rain tight passenger train roof natural ventilator of changing naturally of passenger train realization car that is used for exporting Bangladesh.
Background technology:
At present, the non-air-conditioning passenger train of Bangladesh is to use simple and crude T font side dilution air plant, concrete structure is that the neck of T font is welded in roof as guide, top rectangle square box is strained and fixed with pull bar by cooperating to be connected with guide again, and wind is changed in the both-side opening of rectangle square box and atmosphere perforation realization.This dilution air plant is neither established the windage structure can not realize tangentially changing the wind function again fully, extraneous new wind can directly be poured into guest room in the car in a large number when the speed of a motor vehicle or extraneous wind speed are big, to forming air-shock wave in the car, influence guest room environment in the car, also be unfavorable for that the waste gas of guest room in the car is discharged this moment; This dilution air plant can not be effectively rainproof in addition, and rainwater can be in a large number into the car when rain is oblique track and falls, so this dilution air plant not exclusively possesses the natural ventilator function.
Because Bangladesh's railway clearance is low, passenger vehicle roof space outerpace little (highly only 61mm) is difficult to realize ventilation, rainproof function in the design.And the China railways gauge is higher relatively, and the passenger vehicle head room is bigger.Therefore, the roof natural ventilator that the China railways passenger vehicle uses is to change on the wind interface in the ventilator bottom to adopt shutter, profile is cylinder or ellipsoid shape, volume is bigger, adopt casting on the technology, can effectively realize ventilating, rainproof two performances, but because of not being used for highly greatly among Bangladesh's passenger train.
Summary of the invention:
Technical problem to be solved in the utility model is: railway clearance is low in Bangladesh, the space that the outside natural ventilator of roof is installed is narrow and small, Width 500mm, short transverse only has 61mm, natural conditions are abominable: high temperature, high amount of precipitation, environment are under the big condition of material corrosion degree, develop can effectively realize ventilating, the roof natural ventilator of rainproof two top performances, to overcome the defective that background technology exists.
The technical solution of the utility model is: comprise guide, the guide outer wall is provided with flange, gusset is located on guide outer wall and the flange, gusset is provided with the ring dish, and the ring dish is near connecting thread cover above the outer radius portion, and guide, flange, gusset, ring dish, screw collar assembly welding become the inner chamber welding assembly, become the outside weldings parts by top board, outer shroud, interior ring assembly welding, the top board below connects outer shroud and interior ring, evenly is provided with four breather ports on the top board between the inner and outer ring, and inside and outside welding assembly links into an integrated entity.
Guide of the present utility model is to pass roof to link to each other with barrier on the Internal decorative roof plate into the car, gusset is provided with the ring dish, the top board below connects outer shroud and interior ring, evenly be provided with four breather ports on the top board between the inner and outer ring, ventilation, rain tight purpose have been reached, dismounting, maintenance are also very convenient, and selecting thickness is the material of main part of the weather-resistant steel plate of 3mm as the roof natural ventilator; Silaatic is a gasket material, and these two kinds of materials are fit to the climatic conditions of Bangladesh.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the B-B revolved sectional view of Fig. 2.
The specific embodiment:
With reference to Fig. 1,2,3, the utility model comprises guide 1, guide 1 outer wall is provided with flange 2, gusset 3 is located on guide 1 outer wall and the flange 2, gusset 3 is provided with ring dish 4, ring dish 4 is near connecting thread cover 5 above the outer radius portion, guide 1, flange 2, gusset 3, ring dish 4, screw collar 5 assembly weldings become the inner chamber welding assembly, by top board 7, outer shroud 8, interior ring 9, backing plate 10 assembly weldings become the outside weldings parts, top board 7 belows connect outer shroud 8 and interior ring 9, evenly be provided with four breather ports 12 on the top board between the inner and outer ring, in, the external welding parts link into an integrated entity by screw collar 5 and screw 11, and the 6th, packing seal.
During use, the screw 11 of at first outwarding winding, remove packing seal 6, make inside and outside welding assembly separately, flange and roof appearance covering tight weld be integral realize the installation of ventilator on roof, in screw, reach execute screw thread fastening glue on the screw after, again packing seal 6 is installed by position among the figure, then inside and outside parts are mounted to one, are connected firmly, promptly finished the installation of roof natural ventilator on roof with screw 11.
