Description

Technical Field

[0001] The utility model relates to the technical field of rail vehicles, in particular to a spoiler device for preventing wind and snow from invading. Background Art

[0002] In rail vehicles with closed equipment compartments under the vehicle, the hot air generated by the air supply unit needs to be discharged to the outside, so a vent must be opened on the bottom plate of the equipment compartment so that the hot air can pass through the air duct of the air supply unit and be discharged to the atmosphere through the vent. In windy and snowy weather, the air supply unit works intermittently. When the air supply unit is working, air flows in the air duct through the vents on the bottom plate to be discharged to the outside, and the wind and snow under the vehicle will not invade the air duct; when the air supply unit is not working, the wind and snow will pass through the vents and invade the air duct, forming ice and blocking the air duct, so that the hot air of the air supply unit cannot be discharged, which will trigger the high temperature alarm of the air supply unit and cause the air supply unit to fail to work normally.

[0003] In order to solve the above problems, the present utility model is provided. Utility Model Content

[0009] The supporting portion is arranged in the through groove and extends toward one end close to the fixing portion, and is used for supporting the air duct of the air supply unit.

[0010] In one embodiment, the height of the spoiler body is greater than the thickness of the vehicle bottom plate, and the vehicle bottom plate is provided with a mounting groove for the spoiler body to pass through.

[0011] In one embodiment, the fixing portion is disposed at one end of the spoiler body in the height direction and extends toward the outside of the spoiler body.

[0012] In one embodiment, the fixing portion extends in a horizontal direction and forms an overlapped portion with the spoiler body to cooperate with the vehicle floor.

[0035] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the utility model and are not limited to the scope of the utility model. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0036] like Figure 1 and Figure 2 , which is a schematic diagram of the structure of an embodiment of the utility model, provides a spoiler device for preventing wind and snow from intruding, including a spoiler body 1 extending from inside the vehicle body to outside the vehicle body, a fixing portion 2 arranged on the periphery of the spoiler body 1, and a supporting portion 3 arranged inside the spoiler body 1.

[0037] The spoiler body 1 is a rectangular parallelepiped structure, and has a through slot 1-1 running through from top to bottom. Figure 6 As shown, the height of the spoiler body 1 is greater than the thickness of the vehicle bottom plate 5, and a mounting slot for the spoiler body 1 to pass through is provided on the vehicle bottom plate 5, so that the spoiler body 1 can extend from inside the vehicle body to outside the vehicle body, that is, extend to the bottom of the vehicle bottom plate 5, to disturb the airflow outside the vehicle. It should be understood that in other embodiments, the spoiler body 1 can also be other shapes.

[0038] The fixing portion 2 is arranged at one end of the spoiler body 1 in the height direction and extends outward from the spoiler body 1 . The fixing portion 2 extends horizontally from the outer wall of the spoiler body 1 and forms an overlap portion with the spoiler body 1 that matches the vehicle floor 5 .
