Description

  The present invention relates to an icing and snow suppressing structure for a moving body that suppresses icing and snowing on the surface of the moving body when the moving body moves.

  Shinkansen vehicles and conventional trains are increasing the speed of commercial operation for the purpose of reducing travel time between cities. In such Shinkansen vehicles and conventional trains, it is known that when snow passes through a snowfall section in winter due to higher speeds, the snow rises and adheres to underfloor equipment and trolleys. is doing. For this reason, measures to reduce the amount of icing snow on railway vehicles are an urgent issue, and the area where icing snow is predicted is heated by a heating device, or the area where icing snow is predicted is blocked. Although the paint is applied, the effect is insufficient. In conventional rail vehicles, inclined dummy members are mounted before and after a hollow recess on the bottom surface of a vehicle body where an upper portion of a vehicle carriage is located (see, for example, Patent Document 1). In such a conventional railway vehicle, by suppressing the flow into the hollow recess by the dummy member, icing snow on the bogie equipment such as the motor, the gear box and the axle box is reduced, and the snow and ice lump from the bogie equipment is on the track. This prevents the ballast on the track from jumping up and damaging the equipment under the floor due to the impact generated when it falls on the floor.

JP 2006-117218 A

  In conventional railcars, since dummy members are mounted before and after the hollow recess on the bottom of the vehicle body, it is possible to suppress icing snow on the hollow recess. There is a problem that cannot be suppressed by. For this reason, in a conventional railway vehicle, there is a possibility that ballast scattering phenomenon in which the ballast on the track jumps up along the track due to the impact that occurs when the snow and ice block falls on the track from the side of the bogie equipment. . Further, in the conventional railway vehicle, when snow and ice blocks fall on the track in the tunnel, the ballast that has bounced up may collide with the inner wall of the tunnel and bounce off and collide with the vehicle to cause damage. Furthermore, in conventional railway vehicles, when removing the dummy member from the bottom of the carriage during vehicle inspection, it is necessary to carry out the removal operation at a slight gap between the track and the bottom of the vehicle body. There is a problem that it takes time and work time.

  In Shinkansen vehicles, as one of measures against cold and snow resistance of vehicles, a body mount structure is adopted in which the bottom of the vehicle except the carriage portion is covered with a cover member in order to smooth the bottom and lower side surfaces of the vehicle. In such a body mount structure, the underfloor device is accommodated between the vehicle underfloor and the cover member, so that the underfloor device is protected from the ballast scattered due to the prevention of icing snow and the falling of the snow ice block. However, such a body mount structure has a problem that icing snow cannot be effectively prevented because the carriage portion cannot be covered and smoothed by the cover member. For this reason, in the Shinkansen vehicle, the side cover is installed on the side of the carriage part. However, if such a side cover is installed, there is a problem that the maintainability is impaired. In addition, since the body mount structure is not widely adopted in conventional line vehicles, the bogie and the underfloor equipment are exposed under the vehicle floor, and there is a problem that icing snow on the bogie and the underfloor equipment cannot be reduced. . Furthermore, in the conventional line vehicle, when a body mount structure is adopted or a cover that covers the underfloor equipment is attached, there is a problem that the manufacturing cost of the vehicle increases.

When the vehicle V shown in FIGS. 1 to 3 is stopped on the track R, the airflow guiding unit 5A is installed within the vehicle limit that is the upper, lower, left, and right limits that the vehicle V should not exceed. As shown in FIG. 4, the airflow guiding portion 5A has a height such that the end surface 5a is substantially flush with the upper surface portion 3a of the underfloor device 3A and the end surface 5b is substantially flush with the lower surface portion 3b of the underfloor device 3A. H is formed by is formed from the side surface portion 3d of the equipment floor 3A~3D to protrude only protruding amount delta ₁ outwardly. The airflow guiding portion 5A is detachably attached to the vehicle V so that it is easy to be removed and attached at the time of vehicle inspection or the like without significantly impairing maintainability. As shown in FIG. 4, the airflow guiding portion 5A is attached to the bottom surface 2a or the side surface 3d of the vehicle body by a support member (not shown) so that the back surface 5c contacts the side surface portion 3d of the underfloor device 3A.

The back surface 5c shown in FIG. 5 (F) is a portion constituting the contact surface of the airflow guiding portion 5A, is formed in a rectangular flat shape, and is connected to the side surface portion 3d of the underfloor device 3A as shown in FIG. It is in close contact with the side surface portion 3d so that air does not flow between them. The inclined surface 5d shown in FIGS. 4 and 5 is a portion inclined outward from the upstream side (front side in the traveling direction of the vehicle V) toward the downstream side (rear side in the traveling direction of the vehicle V), and is a side surface of the underfloor equipment 3A. It protrudes from the part 3d and is formed in a planar shape. The inclined surface 5e is a portion inclined inward from the upstream side toward the downstream side, and is formed in a planar shape so as to protrude from the side surface portion 3d of the underfloor device 3A, similarly to the inclined surface 5d. As shown in FIG. 4, the inclined surface 5e is continuous with the downstream side of the inclined surface 5d.

Next, the operation of the icing and snow suppressing structure for a moving body according to the first embodiment of the present invention will be described.
As shown in FIGS. 1 to 4, when the vehicle V is traveling in the A ₁ direction trajectory snow on R is whirled up, along the side of the vehicle V toward the tail side from the head side of the vehicle V based on the vehicle V snow An air flow F ₁ containing particles flows in the A ₂ direction. When the airflow guiding portion 5A shown in FIGS. 1 to 4 are not present, the airflow F ₁ flowing in the A ₂ direction along the side of the vehicle V shown in FIGS. 2 and 3 of the underfloor devices 3A and floor equipment 3B It flows into the cart 1A from between and flows into the cart 1B from between the underfloor device 3C and the underfloor device 3D. Therefore, the air flow F ₁ collides with the snow particles adhere to the surface of the carriage 1A, floor equipment 3B, snowflakes airflow F ₁ collides with the 3D end surface portions 3c is attached. Further, when the air flow inducing portions 5C does not exist, because the air flow F ₁ flowing in the A ₂ direction along the side of the vehicle V enters the gap between the floor equipment 3B and floor equipment 3C, floor equipment 3C The air flow F ₁ collides with the end surface portion 3c of the steel and snow particles adhere to it.

On the other hand, if the air flow inducing portions 5A shown in FIGS. 1 to 4 is present, the air flow F ₁ flowing in the A ₂ direction along the side of the vehicle V as shown in FIGS. 2 and 3 trolley 1A, 1B of 5 A of airflow guidance parts guide | induced so that it may escape to a side. For this reason, the airflow F ₁ that collides with the surfaces of the carts 1A and 1B is reduced, and the airflow F ₁ that collides with the end surface portions 3c of the underfloor devices 3B and 3D is also reduced. As a result, snow particles adhering to the surfaces of the carts 1A and 1B are reduced, and snow particles adhering to the end surface portions 3c of the underfloor devices 3B and 3D are also reduced, so that icy snow on the vehicle V is suppressed. Further, when the air flow inducing portions 5C are present, the air flow from the gap between the airflow F ₁ flowing in the A ₂ direction along the side of the vehicle V and the underfloor equipment 3B and floor equipment 3C so as to release the side Guide part 5C guides. Therefore, by reducing the air flow F ₁ impinging on the end face 3c of the underfloor devices 3C, and snowflakes reduction adhering to the end face 3c, wearing snow and ice to the vehicle V is suppressed.

For example, when the vehicle V traveling up line in the A ₁ direction travels down line are turned back at the terminus in the A ₂ direction, the air flow F ₂ containing snowflakes along the side of the vehicle V flows A ₁ direction. When the airflow guiding portion 5B shown in FIGS. 1 to 4 are not present, the airflow F ₂ flowing in the A ₁ direction along the side of the vehicle V flows from between the underfloor devices 3A and floor equipment 3B to trolley 1A At the same time, it flows into the carriage 1B from between the underfloor device 3C and the underfloor device 3D. Therefore, the air flow F ₂ collides with the snow particles adhere to the surface of the carriage 1A, snow particles adhere to airflow F ₂ collides with the end face 3c of the underfloor devices 3A, 3C. Further, when the air flow induced portion 5D does not exist, because the air flow F ₂ flowing in the A ₁ direction along the side of the vehicle V enters the gap between the floor equipment 3B and floor equipment 3C, floor equipment 3B The air flow F ₂ collides with the end face part 3c of the snow and the snow particles adhere thereto.

On the other hand, if the air flow inducing portions 5B shown in FIGS. 1 to 4 is present, the air flow F ₂ flowing in the A ₁ direction along the side of the vehicle V as shown in FIGS. 2 and 3 trolley 1A, 1B of The airflow guiding unit 5B guides the air so that it escapes to the side. For this reason, the air flow F ₂ that collides with the surfaces of the carts 1A and 1B is reduced, and the air flow F ₂ that collides with the end surface portions 3c of the underfloor devices 3A and 3C is also reduced. As a result, snow particles adhering to the surfaces of the carts 1A and 1B are reduced, and snow particles adhering to the end surface portions 3c of the underfloor devices 3A and 3C are also reduced, so that icy snow on the vehicle V is suppressed. Further, when the air flow inducing portions 5D are present, the air flow from the gap between the air flow F ₂ flowing in the A ₁ direction along the side of the vehicle V and the underfloor equipment 3B and floor equipment 3C so as to release the side Guide part 5D guides. Therefore, by reducing the air flow F ₂ impinging on the end face 3c of the underfloor devices 3B, also reduces snow particles adhering to the end face 3c, wearing snow and ice to the vehicle V is suppressed.

The moving body icing and snow suppressing structure according to the first embodiment of the present invention has the following effects.
(1) In the first embodiment, induced airflow guiding section 5A~5D airflow F _1, F ₂ towards the expected area of the wearing ice and snow along the side of the vehicle V on the side of this region. For this reason, the air flow to the area | region where icing snow is estimated is escaped to the side, and the amount of icing snow of this area | region can be reduced. In a railway vehicle, when the air flow to an area where icing snow is predicted is released downward, the air flow is guided downward because there is a small gap between the bottom surface of the vehicle V and the track R. It is difficult to achieve the effect of reducing the amount of icy snow on the region where icy snow is predicted.

The airflow guiding portion 6A shown in FIGS. 26 to 29 is a triangular prism-shaped member, and includes end surfaces 6g and 6h, a back surface 6i, and inclined surfaces 6j and 6k. As shown in FIG. 29, the airflow guiding portion 6A is formed at the same height H as the airflow guiding portion 5A, but the protruding amount Δ ₃ (smaller than the protruding amount Δ ₂ of the airflow guiding portion 6A shown in FIG. for example, formed by _{Δ 3 = Δ 2/2)} . As shown in FIGS. 30B and 30E, the airflow guiding portion 6A has an angle ( inclination angle ) θ ₁ sandwiched between the back surface 6i and the inclined surface 6j of 30 °, and the back surface 6i and the inclined surface An angle ( tilt angle ) θ ₂ sandwiched between 6k is formed at 30 °, and an angle ( vertical angle ) θ ₃ sandwiched between the tilted surface 6j and the tilted surface 6k is formed at 120 °. As shown in FIG. 31, the air flow inducing portions 6A is a rear 6i is positioned on the imaginary straight line Y _1, virtual straight line X and the virtual straight line Y ₃ distances upstream and downstream from the intersection of the L ₃ away virtual on a straight line Y _3, the upstream end of the end portion and the inclined surface 6k of the downstream side of the inclined surface 6j is located.

Drifting snow particle measurement device 40A counts the snow particles on the upstream side of the measurement position P _F near carriage 30b, drifting snow particle measurement device 40B counts the snow particles at the measurement position P _R of the downstream side in the vicinity of carriage 30b . Here, the measurement positions P _F and P _R shown in FIG. 32 are both separated from the side surfaces of the underfloor devices 30c and 30d by a distance L ₁₁ = 15 mm and from the ground plane 20c by a distance L ₁₂ = 35 mm. _F is a distance L ₁₃ = 171mm upstream from the center of the carriage 30b, the measurement position P _R are separated by a distance L ₁₃ = 171mm downstream from the center of the carriage 30b.

(experimental method)
A car model with a scale of 1/10 as shown in Fig. 32 and a car body model around the car are manufactured, and in the first cold room of the Shiozawa Snow Damage Prevention Laboratory of the Railway Technical Research Institute, snowfall wind tunnels are used to icing snow. A reproduction test was conducted. In the experiment, a plurality of types of deflectors for reducing the amount of icing snow as shown in FIGS. 1 to 31 are attached in the vicinity of the carriage 30b and the underfloor equipment 30c, 30d, and the amount of icing snow when each deflector is used. The reduction effect was evaluated. The evaluation is based on the value (b / a ) of the number of snow particles ( b ) in the bogie part (b / a ) relative to the number of snow particles on the upstream side ( a ) without the deflector, and when a deflector is installed It was evaluated that the reduction effect was large when the ratio was small. In this test, snow particles with a diameter of 0.1 mm or less were evaluated based on the measurement results of the dominant particle size of soaring snow obtained in the current vehicle test. In the experiment, a deflector for reducing the amount of icing snow was attached only to one side surface of the model vehicle 30.

Table 1 shows the dimensions and test results of the deflector according to the example used in the icing snow experiment. The deflectors according to Examples 1 to 10 shown in Table 1 are the air flow guiding units 5A to 5D and the air flow guiding unit of the icing and snow suppressing structure for moving bodies according to the first to tenth embodiments shown in FIGS. Corresponding to 6A to 6D respectively, the primary deflector corresponds to the airflow guiding portions 5A to 5D, and the secondary deflector corresponds to the airflow guiding portions 6A to 6D. A comparative example is a test result when the deflectors according to Examples 1 to 10 are not attached to the model vehicle 30 shown in FIG. About Examples 1-3, it experimented about two types, large and small in which protrusion amount (DELTA) differs. In Examples 9 and 10, the experiment was performed with the distance L ₁ = 65 mm, the distance L ₂ = 30 mm, and the distance L ₃ = 55 mm shown in FIGS. 25 and 31. The test result shown in Table 1 is the number of snow particles when the deflectors of Examples 1 to 10 are mounted, where 1.0 is the number of snow particles when there is no deflector of the comparative example. For Examples 1-3 and Comparative Examples, the measurement results at the measurement position P _F of the truck near the upstream side shown in FIG. 32, for Examples 4-10 the measurement results at the measurement position P _R of the carriage near the downstream is there.
