Core of the invention is to provide a kind of rail vehicle ventilation device, can adapt to speed and adjusts ventilation quantity, vehicle is high
It is also ensured that ventilation quantity when speed operation.Another core of the invention is to provide a kind of including above-mentioned rail vehicle ventilation device
Rail vehicle, ventilation device can adapt to speed and adjust ventilation quantity, it is also ensured that ventilation quantity when vehicle high-speed is run.
In a kind of specific embodiment of rail vehicle ventilation device provided by the present invention, referring to FIG. 3, include air inlet cylinder,
Two sides of air inlet cylinder are respectively equipped with the first air port 1 and the second air port 9, and the first air port 1 is oppositely arranged with the second air port 9.Into
The top of air duct is equipped with top air port 10 and bottom and is equipped with air outlet 11, under free state, top air port 10, the first air port 1, the
Two air ports 9, air outlet 11 communicate.Be equipped with the first deflector 3, the second deflector 7 in air inlet cylinder and be hinged on the first deflector 3 with
Connecting rod 4 between second deflector 7, connecting rod 4 can be rotated relative to the first deflector 3 and connecting rod 4 can relative to the second deflector 7
Rotation.The top of first deflector 3 is hinged on the position for being located at 1 top of the first air port on air inlet cylinder, the top of the second deflector 7
It is hinged on the position for being located at 9 top of the second air port on air inlet cylinder.First deflector 3, the second deflector 7 pass through the connection of connecting rod 4
Trapezoidal link mechanism is constituted, and upper end is bigger diameter end, the trapezoidal top spacing for referring to two deflectors is greater than bottom spacing
And the shape that spacing gradually decreasees from top to bottom, the i.e. link mechanism are what the spacing of two deflectors from top to bottom was gradually reduced
Structure.Meanwhile second deflector 7 can be rocked to the state in closed second air port 9, i.e. wind cannot circulate at the second air port 9.
It can change air inlet direction and intake by the movement of deflector, connecting rod 4 can play support, limit to deflector
Effect.First deflector 3 can be swung relative to air inlet cylinder, and the second deflector 7 can be swung relative to air inlet cylinder, the first water conservancy diversion
Plate 3, the second deflector 7 realize linkage, the link mechanism that the first deflector 3, the second deflector 7 are constituted with connecting rod 4 by connecting rod 4
It is movable structure relative to air inlet cylinder, wherein since the link mechanism is trapezium structure, the first air port 1 and first can be made
It can be respectively formed flow-guiding channel between deflector 3, between the second air port 9 and the second deflector 7, the wind entered is oriented to out
Air port 11.
For control guiding device intake in a certain range, the guiding device can according to speed automatically adjust two pieces
Angle α between deflector and air inlet cylinder achievees the purpose that adjust intake.
Referring to FIG. 1, deflector and connecting rod 4 return automatically by self gravity when vehicle low speed runs or remains static
Arrive free state again, top air port 10, the first air port 1, the second air port 9, air outlet 11 communicate, wind from ventilation device it is all into
Wind face enters inside air inlet cylinder, including top air port 10, the first air port 1 and the second air port 9.Wherein, since deflector is in gravity
It is sagging under effect, certain block can be played the role of to air port.
Referring to FIG. 2, entire ventilation device installation direction is the advance of front and back air intake surface and vehicle when vehicle high-speed is run
The front-rear direction in direction is consistent.The setting of first air port 1 is pushed connecting rod 4 by the thrust of wind in windward side, the first deflector 3, and
It is had an effect by connecting rod 4 the second deflector 7.When speed reaches the critical value of setting, the second deflector 7 is towards the second air port 9
It is rocked to the position in closed second air port 9, the second air port 9 is in sealing state and cannot divulge information.The position of second deflector 7 determines
After position-limiting action can be played to the first deflector 3 by connecting rod 4, be formed after making link mechanism dynamic equilibrium.In link mechanism
Stable structure after, enter the wind all from the air inlet in the first air port 1, the second air port 9 will not make distinguished and admirable mistake by closed, and first leads
The guiding role of flowing plate 3 can drain wind towards air outlet, and wind is enable to flow out from air outlet, in addition, the top of air inlet cylinder
For negative pressuren zone, part air inlet can be distributed, so that be able to maintain within the set range from the air quantity that air outlet 11 flows out,
Guarantee at high speeds, to guarantee to have always wind to enter in air inlet cylinder by the way that the air port of air inlet cylinder side is arranged in.
Vehicle high-speed run when, 3 stress condition of the first deflector is shown in Fig. 7, the first deflector 3 at directed force F n windward,
It is decomposed into longitudinal Fy and transverse direction Fx stress, lateral Fx stress after 4 the first deflector of reaction 3 of the second deflector 7 and connecting rod by putting down
The gravity Fg of weighing apparatus, longitudinal Fy stress and the second deflector 7 and 4 reaction forces of connecting rod+deflector and connecting rod 4 reaches dynamic equilibrium.
In ventilation device provided by the present embodiment, equipped with the ladder being made of the first deflector, the second deflector and connecting rod 4
The link mechanism of shape carries out water conservancy diversion to wind, which can adaptively adjust the structure of itself under the action of the wind, from
And according to the angle between the variation automatic adjustment deflector of speed and corresponding air port, the ventilation quantity for reaching air outlet 11 is basic
Stable purpose, it is also ensured that ventilation quantity when vehicle high-speed is run.The ventilation device is installed on the logical of locomotive surface negative pressuren zone
The air inlet of blower, according to the air quantity demand in the speed of service and ventilation blower of vehicle or locomotive, ventilation device is automatically regulated
