As shown in fig. 2 and 3, the deflector 4 is a solid plate, and its lateral projection is wedge-shaped, and its end far from the bogie 1 is a wedge head, and its end near the bogie 1 is a wedge tail.
The wedge shape of the guide plate 4 is similar to a right triangle, the top surface of the guide plate 4, which is attached to the bottom plate 6, is a horizontal first plane 41, the end surface of the wedge tail of the guide plate 4 is a vertical second plane 42, and the inclined plane connecting the first plane 41 and the second plane 42 is a guide plane 43.
The included angle between the flow guiding surface 43 and the first plane 41 is a wedge angle, the angle range of the wedge angle may be set to 8 ° to 12 °, for example, 9 °, 10 °, 11 °, and the like, and in this embodiment, the included angle between the flow guiding surface 43 and the first plane 41 is 10 °.
As shown in fig. 4 to 7, the flow guide surface 43 of the flow guide plate 4 is provided with two parallel rows of countersunk grooves 44, each row of countersunk grooves 44 is further divided into a plurality of separated grooves, bolt holes 8 penetrating through the flow guide plate are respectively formed at two ends of each separated groove, and the flow guide plate 4 is connected with the bottom plate 6 through bolts 9 and gaskets 10.
The bottom plate 6 is provided with nuts 11 in an embedded manner at positions corresponding to the bolt holes 8 of the flow guide plate 4, the bolts 9 are connected with the nuts 11 through threads after penetrating through the bolt holes 8 of the flow guide plate 4, so that the flow guide plate 4 is fastened below the bottom plate 6 of the equipment compartment, a gasket 10 is arranged between the bottom plate 6 and the first plane 41 of the flow guide plate 4, in order to install the gasket 10, the bottom plate 6 is designed into a corresponding step shape, namely the thickness of the part, provided with the gasket 10, of the bottom plate 6 is slightly thinner, and after the thickness of the gasket 10 is added, the thickness of the part is basically the same as that of the part without the gasket 10. It will be appreciated that for the purpose of adding the gasket 10, it is also possible to design the step structure in the first plane 41 of the baffle 4 so that the bottom plate 6 has substantially the same thickness.
As can be seen from the figure, since the deflector 4 is wedge-shaped, the length of the bolt 9 near the wedge tail is relatively short, while the length of the bolt 9 near the wedge head is relatively long, after the bolts 9 of both lengths are screwed, the head of the bolt 9 sinks into the interior of the countersunk head groove 44 and does not exceed the deflector surface 43, and when viewed from the side, the head of the bolt 9 cannot be seen, so as to reduce the adverse interference to the turbulent flow field as much as possible, and facilitate the disassembly and assembly.

The above embodiments are merely preferred embodiments of the present invention, and are not limited thereto, and on the basis of the above embodiments, various embodiments can be obtained by performing targeted adjustment according to actual needs. For example, a counter bore corresponding to each bolt 9 is used instead of the counter bore groove 44, or the wedge tail of the baffle 4 is designed to be a non-vertical plane, or the like. This is not illustrated here, since many implementations are possible.
According to the ice-melting and snow-removing device for the bogie, the guide plate 4 is arranged below the equipment compartment bottom plate 6 near the bogie, the flow field of the bogie area is changed, and snow flying in the bogie area is reduced, and particularly, the installation angle of the guide plate 4 can be determined by adopting a digital simulation technology and a wind tunnel test (see fig. 11).
In addition, the bogie ice-melting snow-removing device also improves the temperature field of the bogie area and reduces the accumulated snow condensation of the bogie area by arranging the electric heating plate 5 at the outer side of the equipment cabin end plate 6 near the bogie.
