Another core of the present utility model is to provide a railroad car comprising the above-described obstacle deflector.
Please refer to fig. 1 to 3.
The embodiment discloses a barrier device 01, which comprises a main body structure 1 for being connected with a vehicle body 3, wherein an arc-shaped jet flow groove 2 is arranged on the lower surface of the main body structure, the arc-shaped jet flow groove 2 is symmetrically arranged about the middle section of the barrier device 01, and the middle section is a section along the advancing direction of the vehicle body 3; the jet flow groove 2 penetrates through the front end cambered surface and the rear end plane of the main body structure 1, the air inlet end of the jet flow groove 2 is positioned on two sides of the front end cambered surface of the main body structure 1, and the air outlet end of the jet flow groove 2 is positioned on the rear end plane of the main body structure 1.
In the process of using the barrier 01 provided by the embodiment, when a train runs, the air flow pressure at the front end of the barrier 01 is larger, and because the arc-shaped jet flow grooves 2 are arranged, the air inlet ends of the jet flow grooves 2 are positioned at two sides of the cambered surface at the front end of the main body structure 1, the air flow at the front end of the barrier 01 can enter the jet flow grooves 2 in the process of flowing at two sides of the cambered surface at the front end and flow along the jet flow grooves 2 until being discharged from the air outlet ends of the jet flow grooves 2, the pressure difference resistance generated by the barrier 01 can be effectively reduced, and the air resistance generated by the barrier 01 is reduced.
Compared with the related art, the air inlet ends of the jet flow grooves 2 in the embodiment are located at two sides of the cambered surface of the front end of the main body structure 1, as shown in fig. 2, the cambered surface of the front end of the main body structure 1 is a cambered surface which is matched with the vehicle body 3 and is narrow in front and wide in back, the air pressure of the front end of the main body structure 1 is large, and air enters the jet flow grooves 2 from the air inlet ends at two sides of the cambered surface of the front end, so that the air resistance of the front end of the obstacle deflector 01 can be effectively reduced. Compared with the air inlet end of the jet flow groove 2 arranged at the front end of the main body structure 1, the air flow at the front end of the main body structure 1 can flow to two sides, and the air flow at the front end of the main body structure 1 is split, so that the air flow pressure at the front end of the main body structure 1 is prevented from being large.
On the basis of the embodiment, the opening size of the air inlet end of the jet flow groove 2 can be larger than the opening size of the air outlet end of the jet flow groove 2, so that more air flow can enter the jet flow groove 2, the air inflow of the jet flow groove 2 is ensured, and the air resistance of the front end of the barrier 01 is reduced as much as possible.
In the running process of the train, the air flow at the front end of the barrier 01 flows along the front end cambered surface of the main body structure 1, and when flowing to the opening of the jet flow groove 2, the air flow enters the jet flow groove 2 and flows along the jet flow groove 2, the opening size of the air inlet end of the jet flow groove 2 is set to be larger than the opening size of the air outlet end of the jet flow groove 2, so that more air flow can enter the jet flow groove 2, and the air entering the jet flow groove 2 can flow out from the air outlet end along the jet flow groove 2.
Preferably, the cross section of the jet flow groove 2 can be gradually reduced from the opening of the air inlet end to the opening of the air outlet end, in the running process of the train, the air flow flows from the front end of the main body structure 1 to two sides, when flowing to the opening of the air inlet end of the jet flow groove 2, the air flow enters the jet flow groove 2, the size of the opening of the air inlet end of the jet flow groove 2 is increased, the air flow entering the jet flow groove 2 can be effectively increased, and meanwhile, after the air enters the jet flow groove 2, the shape of the main body structure 1 and the number of the jet flow grooves 2 are limited, the cross section of the jet flow groove 2 is set to be in a gradually reduced structure, and the flow speed of the air flow in the jet flow groove 2 can be ensured.
Specifically, the arc length of the opening of the air inlet end of the jet flow groove 2 may be 228mm to 326mm, the opening size of the air outlet end of the jet flow groove 2 may be 90mm to 110mm, and preferably, the opening size of the air outlet end of the jet flow groove 2 may be 100mm.
It should be noted that, in this embodiment, the arc length of the opening of the air inlet end of the jet flow groove 2 is the arc length of the front end arc surface of the main body structure 1 occupied by the opening of the air inlet end of the jet flow groove 2 in the direction shown in fig. 2, and the opening size of the air outlet end of the jet flow groove 2 is the length size of the rear end plane of the main body structure 1 occupied by the opening of the air outlet end of the jet flow groove 2 in the direction shown in fig. 2.
In a specific embodiment, the number of the jet grooves 2 may be set to be plural, and the plural jet grooves 2 are symmetrically distributed about the middle section of the main body structure 1, so that the generated air pressure is symmetrically distributed about the middle section of the main body structure 1 during the air flow flowing through the jet grooves 2; the middle section of the main body structure 1 is a section parallel to the travelling direction of the vehicle body 3, and the distance between the adjacent jet grooves 2 positioned on the same side of the middle section is 100mm to 213mm.
As shown in fig. 2, since the dimensions of the front end cambered surface and the rear end plane of the main body structure 1 are different, and the opening dimension of the air inlet end and the opening dimension of the air outlet end of the same jet groove 2 are different, the cross section of the space between adjacent jet grooves 2 is not a constant dimension, and may be a tapered dimension as shown in fig. 2, or other forms meeting requirements, which are specifically determined according to the actual situation, and will not be described herein.
Preferably, the inner side surface of the jet flow groove 2 is a smooth arc surface, and the inner bottom surface of the jet flow groove 2 is a smooth plane, so that air flow can smoothly flow in the jet flow groove 2.
Specifically, the main structure 1 can be made of stainless steel or aluminum alloy, and in the process of actual setting, the main structure 1 can be made of an integral structure with the vehicle body 3, the main structure 1 can be made of a plurality of structures provided with jet grooves 2, and the main structure 1 is detachably connected with the vehicle body 3 through a connecting piece.
In a specific embodiment, the projection of the opening of the air inlet end of the jet flow groove 2 to the rear end plane of the main body structure 1 is closer to two sides of the main body structure 1 than the opening of the air outlet end of the jet flow groove 2, so that the jet flow groove 2 is bent towards the middle section of the main body structure 1; in the specific use process, the bending direction of the jet flow groove 2 is shown in fig. 2, so that the space arrangement of the jet flow groove 2 can be more reasonable.
