Description
Technical field
The present invention relates to rail transit locomotive technical field, especially a kind of high-speed rail transportation self-regulation ventilation device
And locomotive.
Background technique
Currently, domestic hot-short or vehicle ventilator inlet air filter screen are mounted on vehicle or locomotive surface, in vehicle or
When locomotive high-speed cruising, the air intake surface at ventilation device is in negative pressure region, and under the effect of same ventilation blower, speed is higher, leads to
Air intake surface vacuum effect at wind apparatus is bigger, and the intake of ventilation blower will be the low even without intake, will affect locomotive
Inside need the work of ventilation blower ventilating and cooling component.
Summary of the invention
The technical problem to be solved by the present invention is to, in view of the shortcomings of the prior art, provide a kind of high-speed rail transportation use from
Adjust ventilation device and locomotive.
In order to solve the above technical problems, the technical scheme adopted by the invention is that: a kind of high-speed rail transportation self-regulation
Ventilation device, including cylinder open at one end；The cartridge openings end is closed by cover plate lid, and the cylinder and the cover board shape
At installation space；Multiple air inlets are offered on the opposite side in two positions of the cylinder, cover board；Installation in the cylinder
There is the flow spoiler that can be moved on vertical direction in the installation space.
The flow spoiler includes a horizontal component；The horizontal component two sides pass through the coupling part for changing wind direction
It is connect with a vertical portion.In the present invention, coupling part surface can be arc；Or coupling part surface is horizontal by one
Angle, and the angle value range is (0 °, 90 °).
Two opposite sides of the cylinder position are equipped with card slot；The vertical portion two sides are equipped with mounting plate；Two pieces
The mounting plate is respectively embedded into two card slots；The vertical portion two sides offers the side of air inlet with the cylinder respectively
Position is opposite.So that ventilation device structure is more compact and firm.
Ball is installed on the mounting plate.Flow spoiler horizontal force is balanced, while flow spoiler is up and down in card slot
When, it is contacted by ball with card slot.
The mounting plate is connect with spring one end；The spring other end is connect with the cover board.Spring, which can be constrained, disturbs
Flow the moving distance of device.
Correspondingly, the ventilation blower air inlet of the locomotive surface negative pressuren zone is equipped with the present invention also provides a kind of locomotive
State ventilation device.
Compared with prior art, the advantageous effect of present invention is that: the present invention can solve ventilation device due to high speed
Cannot enter the wind or enter the wind few problem in the negative pressure that car body surface is formed about when vehicle or locomotive driving, can according to vehicle or
Effective intake of locomotive running speed automatic adjustment ventilation device.

The air inlet state diagram of ventilation device when Fig. 2 is vehicle low speed of the present invention operation or stationary state；
Fig. 3 is the air inlet state diagram of ventilation device when vehicle high-speed of the present invention is run；

Specific embodiment
As shown in Figure 1, one embodiment of the invention includes cylinder 5 open at one end；5 open end of cylinder passes through cover board 1
Lid closes (cover board 1 is fixedly connected with cylinder 5 by fastener 2), and the cylinder 5 and the cover board 1 form installation space 7；Institute
It states two opposite sides of 5 position of cylinder, bottom edge, offer multiple air inlets 6 on cover board 1.
As shown in Figure 1 and Figure 4, flow spoiler 4 includes a horizontal component 41；41 two sides of horizontal component are by for changing
The coupling part 42 of changing wind direction is connect with a vertical portion 43.Opposite two sides for not opening up air inlet in 5 position of cylinder are set
There is card slot 5a (card slot 5a is outwardly protruded)；42 two sides of vertical portion are equipped with mounting plate 4b；Two pieces of mounting plate 4b are respectively embedded into two
In a card slot 5a, ball 4a is installed on mounting plate 4b.Card slot can prevent spoiler from moving in the horizontal direction.When installation,
Horizontal component 41 is connect close to cover board 1, mounting plate 4b with 3 one end of spring；3 other end of spring is connect with cover board 1.Spring can limit
The scope of activities of flow spoiler processed, beyond cover board when preventing flow spoiler mobile.
Such as Fig. 1, the two sides that the part opposite with 41 position of horizontal component of cover board 1 is arranged in the air inlet on cover board 1 (are covered
The 1 not set air inlet in middle part of plate).Under the influence of capable of preventing due to negative pressure, positive air inlet is run out of from side.
Flow spoiler is mounted in the card slot in air inlet cylinder, can be moved up and down in a certain range in card slot, above be moved down
The dynamic constraint by entire stroke and spring.Flow spoiler is for changing the air inlet direction of ventilation device and intake；Ball: balance
Flow spoiler horizontal force, while playing flow spoiler up and down contact action contacted with card slot in card slot.
Entire ventilation device installation direction is that front and back air intake surface is consistent with the direction of advance of vehicle.
In the present invention, coupling part surface can be set to arc or coupling part surface horizontal by an angle,
The angle value range is (0 °, 90 °)
The air inlet operation principle schematic diagram of ventilation device is shown in Fig. 2 and Fig. 3.
Vehicle low speed operation or when stationary state, the air inlet of blower from all air intake surfaces of ventilation device (Internet tablet and into
The front and back air intake surface of air duct) air inlet.
When vehicle high-speed is run, flow spoiler stress diagram is shown in Fig. 3, and flow spoiler is in directed force F windwardNUnder, it is decomposed into vertical
To FYWith lateral FXStress, lateral FXStress after the card slot reaction ball on air inlet cylinder by balancing, longitudinal FYStress and spring shape
The weight F of deformation stress F (F=kx)+flow spoilerGReach dynamic equilibrium, flow spoiler is in FYRise in card slot under effect certain
Height after reach and stablize after longitudinal resultant force dynamic equilibrium.For air inlet all from positive air inlet, flow spoiler rear portion is negative pressure
Area can distribute part air inlet, so that passing through the air quantity of ventilation device lower part within the set range.
Vehicle or locomotive lower or stationary state in speed, in flow spoiler automatic fall-back to ventilation device.It will not influence
The overall appearance of entire vehicle or locomotive.
For control intake in a certain range (air quantity is too big will to cause ventilation blower overcurrent, air quantity too it is small be not able to satisfy it is logical
The ventilation quantity requirement of blower), the flow-disturbing working depth of flow spoiler is automatically adjusted according to speed.Specific method is adjustment spring
The weight F of coefficient of elasticity k or flow spoilerG。
The dynamic balance of flow spoiler in the Y direction is Fy=F+FG。
In order to better ensure that ventilation effect, better solve the negative pressure that car body surface is formed about and cannot enter the wind or into
The few problem of wind, in the present invention, length L and the directed force F windward of the height H of coupling part, horizontal componentN, directed force F windwardN
Longitudinal force FY, horizontal force FXBetween relationship are as follows:
Wherein, ρ is atmospheric density；V is the wind speed windward of flow spoiler；θ is FNWith FXBetween angle；F is spring to flow-disturbing
The resistance of device；FGFor the gravity of flow spoiler.
