Description

Technical Field

[0001] This invention relates to the field of rail transit technology, and in particular to a high-speed train with a flexible anti-splash and anti-icing device. Background Technology

[0002] When high-speed trains operate on snow-covered tracks in winter, severe snow and ice accumulation often occurs in the bogie compartments due to the melting and re-icing of snow particles on the heating elements of the bogies. This snow and ice buildup on the bogie surface results in a large layer of ice covering the car body, significantly increasing the axle load and reducing the stability of the train. When the ice gradually spreads to the bogie area and solidifies, the bogie's motion performance is severely degraded, potentially jeopardizing train safety. Research has found that the main cause of snow and ice accumulation in the bogie compartments is the melting of snow particles into water, which then splashes due to the high-speed rotation of the wheelsets, brake axle discs, and other high-speed rotating structures. Currently, most high-speed train bogie compartments are open, allowing melted snow to splash directly and extensively within the compartment. Existing designs lack anti-splash and anti-icing features for the high-speed rotating structures of the bogies, leading to frequent snow and ice accumulation in the bogie compartments and severely impacting the normal operation of high-speed trains in cold winter regions. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a high-speed train with a flexible anti-splash and anti-icing device for the bogie rotation structure that effectively suppresses the splashing of snow melt water in the bogie cabin during high-speed rotation and improves the stability and safety of high-speed train operation in winter snowfall.

[0004] A high-speed train with a flexible anti-splash and anti-icing device includes a bogie cabin and a bogie, and further includes the flexible anti-splash and anti-icing device, which comprises a flexible suspension plate and a flexible suspension rope. The flexible suspension rope is a flexible, bendable, but non-stretchable rope, and the flexible suspension plate is a flexible thin plate. The flexible suspension plate is suspended from the top of the bogie cabin by the flexible suspension rope and is located directly above the high-speed rotating structural components of the bogie. To solve the above technical problems, the present invention adopts the following technical solution:

[0005] As a further improvement to the above solution:

[0006] The high-speed rotating structural components include wheelsets and brake axle discs.

[0007] The splash-proof and anti-icing device also includes a car body connecting support and a hanging plate connecting support; the upper end of the flexible suspension rope is fixedly connected to a car body connecting section, and the lower end is fixedly connected to a hanging plate connecting section; the car body connecting support is fixedly connected to the bogie cabin, and the car body connecting section is detachably and fixedly connected to the car body connecting support; the hanging plate connecting support is fixedly connected to the flexible hanging plate, and the hanging plate connecting section is detachably and fixedly connected to the hanging plate connecting support.

[0008] The flexible suspension plate is 3-5mm thick and can be naturally twisted to a large extent under the action of wind.

[0009] The flexible suspension rope is selected in different lengths according to the installation position of the flexible suspension plate, so that when the flexible suspension plate is naturally suspended vertically, it maintains a certain interval distance with the bogie.

[0010] The hanging plate connecting support includes a mounting cap and a mounting pin. The flexible hanging plate is provided with a mounting hole. The hanging plate connecting section can be sleeved inside the mounting cap. The mounting pin can pass through the mounting hole from below the flexible hanging plate and be snapped into the mounting cap, so that the mounting cap is fixedly connected to the flexible hanging plate.

[0011] Compared with the prior art, the advantages of the present invention are as follows:

[0012] This invention proposes a high-speed train with a flexible anti-splash and anti-icing device. The flexible hanging plate of the device forms a close-range axial enclosure around the high-speed rotating structural components of the bogie, preventing snowmelt from splashing extensively within the bogie compartment. Simultaneously, the device utilizes flexible ropes and hanging plates, which, under the excitation of high-speed turbulent airflow within the bogie compartment during train operation, achieve passive high-frequency vibration. This dislodges snowmelt splashed from the rotating components from the plate, preventing water droplets from accumulating and condensing on the flexible hanging plate. This effectively avoids snowmelt splashing and condensation within the bogie compartment, suppressing axle load increases and improving the operational stability and safety of the high-speed train. Its structure is simple, and it provides excellent anti-splash and anti-icing effects. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Figures 1 to 5 An embodiment of a high-speed train with a flexible anti-splash and anti-icing device according to the present invention is shown. The high-speed train with the flexible anti-splash and anti-icing device includes a bogie cabin 2 and a bogie 3, and also includes a flexible anti-splash and anti-icing device 1. The flexible anti-splash and anti-icing device 1 includes a flexible suspension rope 12, which is a flexible, bendable, non-stretchable rope, and a flexible suspension plate 11, which is a flexible thin plate. The flexible suspension plate 11 is suspended from the top of the bogie cabin 2 by the flexible suspension rope 12 and is located directly above the high-speed rotating structural component 31 of the bogie 3.

[0022] In this structure, the flexible hanging plate 11 hangs naturally under gravity at the top of the high-speed rotating structure of the bogie 3, which includes components such as wheelsets 311 and brake discs. The flexible hanging plate 11 forms a close-range axial enclosure of the high-speed rotating structure of the bogie 3, preventing snowmelt from the surface of the high-speed rotating structure from splashing extensively within the bogie compartment 2 of the high-speed train. Simultaneously, this anti-splash and anti-icing device uses flexible hanging ropes 12 and flexible hanging plates 11. During train operation, the flexible hanging ropes 12 and flexible hanging plates 11 generate passive high-frequency vibrations under the excitation of high-speed turbulent winds within the bogie compartment 2, thereby dislodging snowmelt splashed from the rotating components from the plate and preventing water droplets from accumulating and condensing on the flexible hanging plate 11. This effectively avoids the splashing and condensation of snow particles or snow water within the bogie compartment 2, suppressing the increase in axle load of the high-speed train and improving the operational stability and safety of the high-speed train. Its structure is simple, and its anti-splash and anti-icing effects are excellent.

[0023] In this embodiment, the high-speed rotating structural component 31 includes a wheelset 311 and a brake axle disc 312. In this structure, the flexible suspension plate 11 is suspended above the wheelset 311 and the brake axle disc 312, which can effectively prevent snow water from splashing out due to the high-speed rotation of the wheelset 311 and the brake axle disc 312.

[0024] In this embodiment, the splash-proof and anti-icing device also includes a body connecting support 13 and a hanging plate connecting support 14; the upper end of the flexible suspension rope 12 is fixedly connected to a body connecting section 15, and the lower end is fixedly connected to a hanging plate connecting section 16; the body connecting support 13 is fixedly connected to the bogie cabin 2, and the body connecting section 15 is detachably and fixedly connected to the body connecting support 13; the hanging plate connecting support 14 is fixedly connected to the flexible hanging plate 11, and the hanging plate connecting section 16 is detachably and fixedly connected to the hanging plate connecting support 14. This structure facilitates the installation or replacement of the flexible hanging plate 11 and the flexible suspension rope 12. The connection method between the connecting section and the connecting support can be bolt connection, pin connection, etc.

[0025] In this embodiment, the flexible hanging plate 11 has a thickness of 3-5mm, allowing it to naturally twist to a considerable extent under wind conditions. This structure enables the flexible hanging plate 11 to twist and generate passive high-frequency vibrations under high-speed turbulent wind excitation, while ensuring that the strength requirements are met.

[0026] In this embodiment, the flexible suspension rope 12 is selected with different lengths depending on its installation position on the flexible suspension plate 11, so that when the flexible suspension plate 11 is naturally suspended vertically, it maintains a distance of 5-10cm from the bogie 3. This structure avoids interference between the flexible suspension plate 11 and the car body or bogie, while ensuring that the flexible suspension plate 11 and the high-speed rotating structural component 31 are within a suitable distance range, thereby improving the coverage performance of the flexible suspension plate 11 on the high-speed rotating structural component 31 of the bogie 3 and improving the splash protection effect of the flexible suspension plate 11.

[0027] In this embodiment, the suspension plate connecting support 14 includes a mounting pin 142 and a mounting cap 141. The flexible suspension plate 11 is provided with mounting holes. The suspension plate connecting section 16 can be sleeved inside the mounting cap 141. The mounting pin 142 can pass through the mounting hole from below the flexible suspension plate 11 and snap-fit ​​with the mounting cap 141, so that the mounting cap 141 is fixedly connected to the flexible suspension plate 11. In this structure, the suspension plate connecting support 14 has a simple structure and good flexibility and stability. The distribution of mounting holes can be flexibly adjusted according to the size and coverage contour of the flexible suspension plate 11 to ensure the hoisting stability of the flexible suspension plate 11. Furthermore, the number and position of the vehicle body connecting supports 13 should correspond to the number and position of the mounting holes to ensure that the flexible suspension plate 11 can be vertically suspended directly above the high-speed rotating structural component 31 of the bogie 3.

[0028] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
