Problems solved by technology

[0003] At present, the blades of the louvers are fixed and are always open. The opening and closing of the blades cannot be adjusted according to the demand, which can meet the fresh air supply and the heat dissipation and exhaust of the cooling device when the diesel engine is started.
However, when the diesel engine is shut down, the blinds cannot be closed, which will affect the thermal insulation effect inside the car, especially in winter, which will reduce the temperature inside the car and affect the heating effect of the oil furnace.
There is no overlap between the existing louver blades, and rainwater is easy to splash into the car during use, affecting the use of users

Embodiment 1

[0024] Embodiment 1, a side wall louver device of a railway passenger car, such as figure 1 As shown, the window frame 1 is included, and the outer side of the window frame 1 is provided with a dense mesh 13 .

[0025] like figure 2 , 3 As shown in and 5, a number of rotating shafts 2 are evenly distributed side by side in the window frame 1, and blades 3 are arranged on the rotating shafts 2. The included angle between the folded edge 31 and the blade 3 is an obtuse angle.

[0026] like figure 2 , 3 Shown in and 4, the same end of rotating shaft 2 is hinged with linkage rod 4. The rotating shaft 2 includes a driving shaft 21, which is a driven shaft 22. The driving shaft 21 includes a pair of short shafts 211. The two short shafts 211 are connected by a shaft sleeve 212. The shaft sleeve 212 is fixed to the blade 3 by a shaft sleeve sealing plate 213. On, one of the short shafts 211 is connected with the regulator 5 . The adjuster 5 is a worm gear box, wherein the wo...

Embodiment 2

[0030] Embodiment two, a kind of shutter device of the side wall of railway passenger car, such as Image 6 As shown, the bottom of the window frame 1 is provided with a drainage port 11 and a deflector 12 is provided under the drainage port 11 .

[0031] The design of blade 3 adopts the principle of labyrinth, and a part of it overlaps during the action, which can effectively block the rainwater outside the blade 3, slide along the outside of the blade 3 to the bottom of the window frame 1 and fall on the deflector 12, and then flow along the deflector. Flow plate 12 flows out of the window.

[0032] The present invention can be widely applied to on-line passenger cars, effectively solves the problem that the louver blades 3 of railway passenger car machine rooms cannot be adjusted, and simultaneously solves the problem of poor thermal insulation effect in the car due to lack of sealing. The solution has the advantages of small amount of modification, low cost and remarkable...

Abstract

The invention discloses a louver device for a side wall of a railway passenger car, which comprises a window frame, in which a plurality of rotating shafts are evenly distributed side by side, each of which is provided with blades, and a linkage rod is hinged at the same end of the rotating shaft; the rotating shaft includes a driving shaft , the rest are driven shafts, and one end of the driving shaft is provided with a regulator that drives the rotation of the driving shaft. It can manually adjust the opening and closing, so as to effectively protect the diesel engine and other equipment in the shutter.

Description

technical field [0001] The invention relates to a shutter, in particular to a shutter device for a side wall of a railway passenger car. Background technique [0002] At present, the railway passenger cars with machine rooms need to be equipped with shutters for the ventilation of the machine room. When the diesel engine is running, the air intake system needs to replenish a large amount of fresh air, which can be supplemented from outside the car through the air intake shutters. At the same time, the diesel engine will generate a lot of heat when it is running. After being cooled by the cooling device, the hot air will be discharged out of the car through the exhaust louver by the fan. [0003] At present, the louver blades used are all fixed and are always open. The opening and closing of the blades cannot be adjusted according to the demand, which can meet the fresh air supply and cooling device cooling and exhaust when the diesel engine is started. However, when the die...
