The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
As depicted in figs. 1 and 2, a kind of pantograph flow guiding device 1 of guideway vehicle, comprise being positioned at two side streamlined reefer housings 2 that the pantograph both sides vertically are provided with along roof, and two forward and backward streamlined reefer housings 3 that before and after pantograph, are provided with, be provided with ringwise along roof pantograph periphery.
As shown in Figure 1, the first embodiment of the present invention, two side streamlined reefer housings 2 and two forward and backward streamlined reefer housings 3 are continuous integral structure,
As shown in Figure 2, the second embodiment of the present invention, two side streamlined reefer housings 2 and two forward and backward streamlined reefer housings were arranged in 3 minutes, and two forward and backward streamlined reefer housings 3 are arranged on the centre of two side streamlined reefer housings 2.
When the vehicle high-speed cruising, the noise that pantograph produced mainly is the friction that comes between pantograph and the air, stop the friction between air and the pantograph, will reduce noise, the setting of side streamlined reefer housing 2 just can stop crosswind directly to blow to pantograph, thereby reduce the influence of crosswind, reduced the sound pollution source of pantograph pantograph.
Shown in Fig. 3 to 6, the height of side streamlined reefer housing 2 is high more, the effect of its sound insulation is good more, also can corresponding increase running resistance but side streamlined reefer housing 2 is too high, so the height of side streamlined reefer housing 2 can not be too high can not be low excessively, cross the effect of low out of reach sound insulation, according to the structure measuring and calculating of most of pantographs, the height of the distance from top roof of general side streamlined reefer housing 2 just can satisfy above-mentioned requirements between 450mm to 850mm.
It is up-narrow and down-wide trapezoidal that the vertical section of side streamlined reefer housing 2 roughly is, make its two windward side in the vertical and airflow direction when the vehicle high-speed cruising form certain included angle, windstream just can upwards flow along obliquely windward side like this, just can reduce the windage of side streamlined reefer housing 2 when vehicle operating relatively, the noise that is produced in the time of also can reducing simultaneously side streamlined reefer housing 2 itself with windage.The angle at two trapezoidal base angles 4 is generally between 20 ° to 45 °, and this angle is more little, and windage will be more little, but because the length of roof is certain, if the angle too small at two trapezoidal base angles 4, it is low that the height of side streamlined reefer housing 2 is spent, and can not satisfy the requirement of sound insulation.
For alleviating the single-piece weight of side streamlined reefer housing 2, it is too big that its horizontal width can not be done, but when the vehicle high-speed cruising, the lateral force of side streamlined reefer housing 2 is very big, so need to strengthen the width of bottom, satisfies its mechanics requirement, and it is fixing that it is stabilized in more.For addressing this problem, having established a chamfering 5, be used to widen the width of side streamlined reefer housing 2 bottoms with the middle and lower part of the side of the corresponding side streamlined reefer housing 2 of pantograph, the radius of chamfering 5 can be between the R15mm to R40mm.Equally, chamfering 5 is set, also can plays and reduce the windage effect, thereby further reduce the influence of windstream pantograph at this place.
Same in order to alleviate the weight of side streamlined reefer housing 2, side streamlined reefer housing 2 is designed to the casing shape structure of hollow, but the strength and stiffness that can cause side streamlined reefer housing 2 like this do not satisfy the requirement of vehicle high-speed cruising, in order to strengthen its strength and stiffness, inner transverse at side streamlined reefer housing 2 is provided with a plurality of first reinforcement gussets 6, first strengthen gusset 6 side streamlined reefer housing 2 in by the end to the setting of pushing up, first shape and the side streamlined reefer housing 2 in-to-in shapes of strengthening gusset 6 are complementary, and be fixed on the inwall of side streamlined reefer housing 2, but in order to alleviate the weight of side streamlined reefer housing 2, cost-cutting, side streamlined reefer housing 2 and first is strengthened gusset 6 and is all made by glass-reinforced plastic material, because the requirement of glass-felt plastic manufacture craft is also because in order to reduce windage, the top of side streamlined reefer housing 2 makes arc line type.So as shown in Figure 4, first top of strengthening gusset 6 does not arrive the top of side streamlined reefer housing 2, and this does not influence the strength and stiffness of side streamlined reefer housing 2, because the main force part of side streamlined reefer housing 2 is in its bottom.
For the requirement of the strength and stiffness that satisfy side streamlined reefer housing 2, can not increase the weight of side streamlined reefer housing 2 again, so that first quantity of strengthening gusset 6 is difficult for is too much or very few, generally strengthen gusset 6 with the pitch arrangement first of 200mm to 500mm.
Because the bottom of side streamlined reefer housing 2 is stressed bigger,, strengthens gusset 6 in each first bottom of strengthening gusset 6 near first one second reinforcement gusset 7 is set again in order to increase the strength and stiffness of its bottom.
As shown in Figure 4, strengthen on the side of gusset 6 one deck expanded material 12 being arranged first, it mainly is for when glass-felt plastic is made, and satisfies the requirement of the typing of glass-felt plastic.
Under the requirement of the strength and stiffness that satisfy side streamlined reefer housing 2, in order further to alleviate the weight of side streamlined reefer housing 2, can open some openings 14 in the side bottom of a side of side streamlined reefer housing 2 relative pantographs, will stagger and first strengthen gusset 6 and second and strengthen gusset 7 in the position of these openings 14.
In order to cover the top of car low-voltage electrical part, improve the aerodynamic performance of vehicle, be provided with forward and backward streamlined reefer housing 3.By using forward and backward streamlined reefer housing 3, can cover the low voltage equipment of roof, thus the whistle can reduce high-speed cruising the time, forward and backward streamlined reefer housing 3 must be established the maintenance of inspection door 11 in order to the roof electric equipment.3 pairs of air-flows of forward and backward streamlined reefer housing have certain refraction action, can reduce the pneumatic resistance of pantograph equally.
As shown in Figure 7, the vertical section of forward and backward streamlined reefer housing 3 is roughly triangular in shape, the leg-of-mutton front rake 8 excessive air resistance coefficientes that then can strengthen car body in vertical section, increase air resistance, too smallly then can not effectively reflect air-flow, and cover the space is less down, generally be advisable with 15 ° to 45 °.Forward and backward streamlined reefer housing 3 adopts the nurbs surface moulding, guarantees seamlessly transitting between rake and hypsokinesis face, streamlined reefer housing and the roof curved surface.
Forward and backward streamlined reefer housing 3 is a shell shape structure, and its inside is provided with a plurality of reinforcement gussets 9, and the spacing between the described reinforcement gusset 9 is 200mm to 500mm.
Extremely shown in Figure 8 as Fig. 3, this device also comprises a mount pad 10, the bottom of side streamlined reefer housing 2 is provided with a plurality of detachable caps 13 that are used for hold-down bolt, open detachable cap 13, pass with bolt side streamlined reefer housing 2 is fixed on the mount pad 10, close detachable cap 13 then, 3 of forward and backward streamlined reefer housings directly are fixed on the mount pad 10,10 of mount pads are welded on the roof in advance, can make like this side streamlined reefer housing 2 more firm stable be fixed on the roof.
