Hit, the rubber bag tank material of lightweight is constituted.The installation frame 9 being positioned at cavity type structure side passes through bottom a rectangular shaped rim and train
Respective outer side edges is installed, and is positioned on the end face 8 of this cavity type structure opposite side and adds a reinforcement framework 15, this reinforcement framework
15 drive the stretching, extension of cavity type structure to open or shrink the drive mechanism closed up with one is connected (seeing Fig. 2), so can be preferably
Ensure that, under the effect of drive mechanism, end face will not deform, other faces then can deform rapidly realize stretching, extension open or
Contraction is closed up.In the present embodiment, the cavity type structure of the first deflector 18 and the second deflector 1 is a hermetic type cavity 19,
And only a side opening (seeing Fig. 2) of frame 9 is being installed, form sealing by installing frame 9 with train polycrystalline substance.So
When actuator (the most above-mentioned first actuator and the second actuator) can be avoided to move, snowflake is drawn in actuator, protects
The stable operation of card actuator.
As shown in Figure 4, the drive mechanism in the present embodiment uses an air-cylinder type drive mechanism, the i.e. first deflector 18 and second to lead
Stream plate 1 is driven it to stretch by an air-cylinder type drive mechanism and opens or shrink and close up, and this air-cylinder type drive mechanism includes double acting
Formula cylinder 4 and the air accumulator 13 connected with double-acting type cylinder 4, the gas between air accumulator 13 and often group double-acting type cylinder 4
A double-acting type electromagnetic valve it is provided with on road；Wherein, air accumulator 13 and the double-acting type cylinder 4 driving the first deflector 18
Between gas circuit on be configured with the first double-acting type electromagnetic valve 12, air accumulator 13 and the double-acting type gas driving the second deflector 1
The second double-acting type electromagnetic valve 14 it is configured with in gas circuit between cylinder 4.Drive the double-acting type cylinder 4 of the first deflector 18
One end is fixed in the train body transom (not shown) in bogie region by mounting seat 2 and bearing pin 3, and the other end leads to
Cross deflector bearing pin 5 and water conservancy diversion panel seat 6 is secured on the end face 8 of the first deflector 18；Drive the double acting of the second deflector 1
One end of formula cylinder 4 is fixed on the end plate 11 in bogie region by mounting seat 2 and bearing pin 3, and the other end passes through deflector
Bearing pin 5 and water conservancy diversion panel seat 6 are secured on the end face 8 of the second deflector 1.By using aforementioned air-cylinder type drive mechanism, can be
On the premise of keeping lower cost and simplifying structure, first deflector 18 and the synergism of second deflector 1 is better achieved,
Avoid bogie accumulated snow；And, by arranging double-acting type electromagnetic valve, the fortune of the positive and negative direction of train can be better adapted to
Dynamic.
In the train bogie region anti-accumulated snow device of the present embodiment, the height of first deflector the 18, second deflector 1, first
The inclined plane of deflector 18 and the angle α of horizontal plane, the inclined plane of the second deflector 1 and the angle β of horizontal plane, bogie district
The length etc. in territory, these parameters all can be determined by test or simulation calculation.
Therefore, in concrete installation application, preferably respectively fill a set of anti-accumulated snow of the present utility model in each bogie region
Device, often overlaps anti-accumulated snow device and all includes two actuators (the most above-mentioned first actuator and the second actuator), each holds
Row mechanism all includes one group of double-acting type cylinder and a double-acting type electromagnetic valve, the pressure-air that its power is shared vehicle-mounted.
The operation principle of the train bogie region anti-accumulated snow device of the present embodiment as shown in Figure 4, when train is to right travel, is stored up
Pressure-air in gas tank 13 is through 1 end of the second double-acting type electromagnetic valve 14, to the double-acting type gas of rear end, bogie region
1 end inflation of cylinder 4, it drives the double-acting type cylinder 4 of rear end to shrink, and then drives the second deflector 1 contraction to close up also
It is adjacent to end plate 11；Meanwhile, the pressure-air in air accumulator 13 flows through 2 ends of the first double-acting type electromagnetic valve 12, gives and turns
2 end inflations of the double-acting type cylinder 4 to front end, frame region, the double-acting type cylinder 4 of front end, bogie region stretches out, and enters
And promote the first deflector 18 to stretch towards bogie 17 and open, make the spacing between the first deflector 18 and bogie 17 front end
Reduce；The inclined plane that the stretching, extension of the first deflector 18 is unfolded into forces the air-flow of front lower to deviate to rail level, it is to avoid air-flow enters
Enter bogie region, owing to air-flow being carried secretly snowflake, therefore decrease the snowfall entering bogie region；And the second deflector
1 is in contraction and closes up state, and when its inclined plane formed makes bottom airflow be washed into second deflector 1 at rear, air-flow is still
Rearward move, it is to avoid air-flow refluxes to bogie region, owing to air-flow being carried secretly snowflake, therefore decrease and enter from afterbody
The snowflake in bogie region；First deflector 18 and the common effect of the second deflector 1, greatly reduce the long-pending of bogie region
Snow.When train inverted running, the second double-acting type electromagnetic valve 14 is switched to 2 ends, and the first double-acting type electromagnetic valve 12 is cut
Change to 1 end, make the double-acting type cylinder 4 of bogie 17 both sides produce contrary action, but operation principle and train forward row
When sailing identical, thus equally reduce the generation of accumulated snow.When train enters garage or stops for a long time, bogie 17 liang
First deflector 18 of side and the second deflector 1 are all packed up under the effect of double-acting type cylinder 4, and it can be made to return to inoperative
State.As can be seen here, apply train bogie region of the present utility model anti-accumulated snow device by installing, can transport at not reduction of speed
The safety in operation of train is as much as possible ensured on the premise of row.
