Embodiment
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings：
As shown in figure 1, the invention provides a kind of rail vehicle water conservancy diversion snow protection device, including bogie 1, in bogie 1
Space is provided with equipment compartment 2 under other cars in addition, and for installing equipment under car, equipment compartment 2 plays preferably to equipment under car
Protective effect.
Equipment compartment 2 is surrounded by bottom plate 3 and the skirtboard of both sides 4, and in the position of installation bogie 1, the bottom plate 3 of equipment compartment 2 is
Getting around bogie 1 can all be recessed upwards, be the slot milling of bogie 1, and bottom plate 3 here is by along before and after vehicle traffic direction
The end plate 5 and top plate 6 at both ends form.Vehicle is in high-speed cruising, gap that fraction can be between bottom plate 3 and bogie 1
Into bogie 1, flowed out further around crossing after bogie 1 from rearward end.In the prior art, two end plates 5 are to be vertically arranged, this reality
Apply in example, in order to improve enter bogie 1 after air velocity distribution distribution, former and later two end plates 5 are obliquely installed, from it is lower to
On to the direction of bogie 1 tilt, between the top of end plate 5 and top plate 6 by arc transition or pass through a knuckle plate transition, pass through
Lot of experiment validation, the angle α between end plate 5 and horizontal plane are preferably between 50-70 °, to obtain optimal air velocity distribution point
Cloth, inclined end plate 5 introduce air-flow the top of bogie 1 obliquely, beneficial to air flow, reduce air drag.
As shown in figure 1, each on the end plate 5 of rear and front end set a kuppe 7 protruded to the direction of bogie 1, this
In embodiment, then two kuppes 7 are preferably separately positioned on to the bottom of former and later two end plates 5, i.e. vehicle bottom air-flow enters
At gas port.Mounting seat 12 is welded with end plate 5, kuppe 7 is fixed in mounting seat 12 by multiple bolts 13, installation
Dismounting is very convenient, and will not be limited by the position installing space of bogie 1, can be changed on the basis of existing car
Make.So, vehicle bottom air-flow is under the barrier effect of kuppe 7, into bogie 1 before need to get around kuppe 7, not only change
The direction of local air flow is become, has coordinated with inclined end plate 5, advantageously in the flowing of air-flow, subtracted moreover, kuppe 7 is relative
Lack the interval area between chassis 3 and bogie 1, drastically reduce the area the air inflow of the air-flow into the part of bogie 1, gas
The snow that is mingled with stream, sand and dust etc. are also greatly decreased therewith, and kuppe 7 itself also blocks part snow, sand and dust enter bogie 1,
Snow defence, anti-dust effect are served to greatest extent.Kuppe 7 is all set on the end plate 5 of rear and front end, is to meet
The requirement of vehicle difference traffic direction.
As depicted in figs. 1 and 2, in order to reach optimal barrier effect, width of the kuppe 7 along car body is elongated to be set
Put, the length of kuppe 7 is equal to or more than the wheelspan of two wheels 8 on bogie 1, so as to ensure to reduce to greatest extent snow,
Sand and dust enter the possibility of bogie 1.In order to improve the flow field of airflow passes kuppe 7, the vertical Section Design of kuppe 7 is three
Angular, the base of kuppe 7 is horizontal or slightly tilts down, preferably to play a part of stopping air-flow, the nose angle of kuppe 7
β angle is preferably 60 °, and for nose angle β by arc transition, height H of the kuppe 7 on vertical is 200~220mm, width L
For 2400mm, the front end of kuppe 7 avoids kuppe 7 and wheel 8 along apart from minimum spacing be 160mm with the edge of wheel 8
Contacted in running, and reduce bogie position bottom opening area, enter snowfall so as to reduce from opening.
Kuppe 7 can use solid or hollow metallic article, in order to further improve its snow defence, sand prevention performance,
As depicted in figs. 1 and 2, in the present embodiment, kuppe 7 is preferably using the capsule shape structure closed made of elastomeric material, rubber
The hardness of glue is moderate, and so, when air-flow flows through kuppe 7, kuppe 7 is constantly trembled in the presence of air-flow made of rubber
It is dynamic, the deposition of snow, sand and dust etc. is further avoided, reaches snow defence, the purpose of sand prevention.In addition, it can also be subtracted using capsule shape structure
The weight of light kuppe 7, meets light-weighted requirement.As shown in Fig. 2 mounting seat 12 setting up and down two, mounting seat 12 is
The structure of interlayer, the interlayer of the upper following insertion mounting seat 12 of kuppe 7 is interior to tighten fixation with bolt 13.
The surface of kuppe 7 is shiny surface, prevents ice and snow from gathering, and is also convenient for ice and snow and is come off from surface, local to increase concave bar,
To increase rigidity.
As shown in Fig. 1 and Fig. 3, Fig. 4, in the present embodiment, it is convex on the skirtboard 4 of the rear and front end of bogie 1 to be each provided with one
For the deflector 9 of skirtboard 4, deflector 9 vertically prolongs in the box structure of the substantially elongated closing of vertical direction
Setting is stretched, the vertical height of deflector 9 is selected between 200~220mm, and the vertical height of deflector 9 will cover bogie 1
At the breach 10 for the skirtboard 4 put, snow is reduced to greatest extent, sand and dust enter bogie 1.All set on the skirtboard 4 of rear and front end
Deflector 9 is put, is to meet the requirement of vehicle difference traffic direction.
As shown in figure 4, the horizontal section of deflector 9 is hollow hat-shaped structure, the both sides and top of hat are circular arc
Transition, substantially it is made up of three sections of camber lines.It is mingled with the air-flow of snow, sand and dust when flowing through deflector 9 at a high speed, has in deflector 9
In the presence of cambered windward side, centrifugal force is produced, because the proportion of snow, sand and dust is heavier than air, and then in the work of centrifugal force
With, snow and sand and dust are separated with air, snow and sand and dust are thrown out of, and snow and sand and dust will not bypass deflector 9 and enter bogie 1,
Only air then enters the position of bogie 1 around deflector 9.
As shown in figure 4, by lot of experiment validation, in order to reach optimal centrifugation, the camber line half of the both sides of deflector 9
Footpath R1 and R2 are preferably between 50mm~70mm, and the width 2H of deflector 9 in the horizontal plane is preferably 120mm, and thickness H preferably exists
Within 60mm, deflector 9 can use thickness H identical structures from top to bottom, can also as shown in figure 3, thickness H from top to bottom
Gradually change, upper and lower ends are relatively thin, middle relatively thick, are so more beneficial for avoiding snow and sand and dust at breach 10
Into bogie 1, thickness H selection will ensure vehicle gauge requirement, and distance D of the edge of deflector 9 far from the breach of skirtboard 4 is
More than 160mm.
Deflector 9 is using metallic articles such as stainless steels, and to ensure that it has enough strength and stiffness, kuppe 7 passes through
The mode of welding is directly welded on skirtboard 4, can also be mounted by means of bolts on skirtboard 4.
As shown in figure 1, being each provided with half skirtboard 11 at the breach 10 of the skirtboard 4 of the both sides of car body 1, half skirtboard 11 covers
The top half of bogie 1, half skirtboard 11 is streamlined consistent with the skirtboard 4 of the rear and front end of bogie 1, and half skirtboard 11 can be with
Guide the air-flow of car body both sides, reduce the air inflow of the air-flow entered in bogie 1, the snow being mingled with air-flow, sand and dust etc. also with
Be further greatly decreased, while protect bogie air spring and altitude valve, reduce running resistance.
As described above, the plan content with reference to given by accompanying drawing, can derive similar technical scheme.In every case it is not de-
From the content of technical solution of the present invention, any simple modification made according to technical spirit of the invention to above example, etc.
With change and modification, in the range of still falling within technical solution of the present invention.
