Description

Technical Field

[0002] When high-speed EMUs operate on snowy tracks in cold, high-altitude conditions, aerodynamic airflow can sweep up snow on or near the tracks, creating a cloud of snow. This cloud, along with the drifting snow in the air, is swept into the bogie area by the airflow, where some of it accumulates and forms snow blocks. Others melt upon contact with heat-generating components such as traction motors, brake components, and gearboxes. The phase transition of liquid water in the cold air causes ice to form on the surfaces of these components.

[0003] The existing snow removal device cannot be adjusted based on the speed of the train and the amount of snow in the environment. It uses a fixed-angle snow plow device installed at the front end of the bogie frame to remove snow, which seriously restricts the anti-ice and snow function of the snow removal device. Long-term snow removal will cause the snow removal or spoiler components of the snow plow device to wear, resulting in poor snow removal effect.

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0056] The core of the present invention is to provide an anti-ice and snow spoiler device, train vehicle, control method, device and medium to solve the technical problem that the existing snow removal device cannot be adjusted based on the speed of the train and the amount of snow in the environment, and the snow removal efficiency is poor due to fixed angle snow removal.

[0057] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0058] It's important to note that snow and ice accumulation on train bogies can pose a series of problems for train operation quality: ice on the brake calipers can cause the EMU's brake relief system to fail, rendering it inoperable and seriously impacting its transport efficiency; ice on the primary and secondary suspension systems can reduce vibration damping, impacting passenger comfort and, more seriously, posing a major safety hazard; and ice on the gearbox can allow moisture to seep into the gearbox, affecting proper gear operation and endangering train safety. Ice falling from high-speed EMUs can also damage wayside electrical facilities, all of which can jeopardize train operation and driving safety. Existing methods for clearing snow from tracks, such as spray de-icing equipment and snowplows, reduce ice and snow intrusion under trains and mitigate ice formation in key areas under the train, as well as in-station de-icing maintenance on bogies, can ensure normal train operation, but they are expensive and time-consuming.

[0059] At present, in order to solve the problem of ice formation on key parts of the bottom of trains when running in winter snowy weather in high latitudes, there are two main aspects: (1) Suppressing the snow on the roadbed from being swept by airflow and entering the bogie area: one method is to use large-scale de-icing equipment to remove the snow on the roadbed; the other method is to not only use large-scale snow removal locomotives to remove the snow on the roadbed, but also use spraying equipment to spray the snow on the roadbed, increase the water content of the snow, and increase the critical take-off speed of the snow to achieve the purpose of suppressing the snow on the roadbed from being swept by airflow and entering the bogie area, thereby reducing the snow and ice on the bogie surface; (2) De-icing the ice on the bogie surface: using hot air baking method, hot air de-icing method, circulating heating propylene glycol, hot water de-icing method and other methods to perform de-icing maintenance on the bogie within the station section. Track snow removal equipment cannot completely remove the snow, and a large amount of snow still enters the bogie area, causing snow and ice on the bogie surface.

[0060] All of the above methods have the problems of large investment and lag. The use of spray deicing equipment and snow removal vehicles to clear the snow on the line can reduce the entry of ice and snow into the bottom of the train and alleviate the icing of key parts of the bottom of the train. In addition, the de-icing maintenance of the bogies in the station section can ensure the normal operation of the train, but there are the defects of large investment and long time consumption.

[0061] The existing snow plow device includes a snow shovel, a mounting base and a crossbeam steel pipe. The snow plow device, which is connected into one by the mounting base, the snow shovel and the crossbeam steel pipe, is installed at the front end of the bogie frame. It can effectively remove snow accumulated on the track and avoid equipment failures such as short circuits due to excessive snow accumulation. There is also an anti-ice and snow diversion device to improve the flow field distribution state in the bogie area, prevent the air flow from blowing ice and snow to the bogie area, achieve the purpose of reducing ice and snow accumulation in the bogie area, and improve the EMU's own anti-ice and snow ability. However, the snow removal device or anti-ice and snow spoiler device that has been proposed or installed cannot be adaptively adjusted based on the speed of the train and the amount of snow in the environment, which seriously restricts the function of the train snow removal device or the anti-ice and snow spoiler device, and the anti-ice and snow effect on the bogie area is not very obvious. The anti-ice and snow spoiler device provided by the present invention can solve the above technical problems.

[0062] Figure 1 A structural diagram of an anti-ice and snow spoiler device provided by an embodiment of the present invention, such as Figure 1 As shown, the anti-ice and snow spoiler device includes a spoiler 1 and a deflection mechanism 2, and the deflection mechanism 2 includes an anti-ice and snow controller 3 and a telescopic component 4; the spoiler 1 is provided on both sides of the central symmetry line of the anti-ice and snow controller 3, and the spoilers 1 on both sides are connected by a rotary pin 5 at the central symmetry line;

[0063] The end of the spoiler 1 away from the rotating pin 5 is connected to the telescopic part 4 through the first rotating connecting part 6;

[0064] The telescopic component 4 is connected to both sides of the anti-ice and snow controller 3 through the second rotating connecting component 7;

[0065] The anti-ice and snow controller 3 is used to obtain the current working condition information of the train, and determine the corresponding spoiler angle based on the current working condition information. According to the spoiler angle, the second rotating connecting component 7 is determined to open the corresponding angle to pull the telescopic component 4, and control the spoiler 1 to perform anti-ice and snow operations.

[0066] Specifically, the device includes a spoiler and a deflection mechanism. The spoiler is rotatable, and the deflection mechanism adjusts the angle of the spoiler. The deflection mechanism includes an anti-ice and snow controller and a telescopic component. The anti-ice and snow controller is used to control the opening and closing angle of the telescopic component, and the telescopic component is connected to the spoiler. The spoiler is arranged on both sides of the central symmetry line of the anti-ice and snow controller. It should be noted that there can be multiple anti-ice and snow controllers or only one. When there are multiple anti-ice and snow controllers, the anti-ice and snow controllers are placed at the front end of the train, dividing the snow removal area at the front end equally. When there is only one anti-ice and snow controller, the anti-ice and snow controller is located at the front end of the train, and the spoiler is located on both sides of the center line of the front end of the train. The swivel pin is located at the center line to connect the spoilers on both sides.

[0067] The two spoilers are connected at the connection point by a rotating pin, and the two ends of the two spoilers away from the rotating pin are respectively connected to the telescopic parts through the first rotating connecting parts, and the telescopic parts are respectively connected on both sides of the anti-ice and snow controller through the second rotating connecting parts, so that the spoilers can rotate freely around the rotating pin.

[0068] The anti-ice and snow controller is used to obtain the current operating condition information of the train. Its operating condition information includes not only the train information of the train itself, but also the depth and thickness of snow accumulation in the external environment and the current wind speed, that is, the density of the falling snow. It should be noted that the wind speed in this embodiment can be distinguished from the different wind speeds of the spoilers on both sides of the anti-ice and snow controller. In this case, the spoiler angles on both sides will be different. It is also possible not to distinguish the different wind speeds of the spoilers on both sides of the anti-ice and snow controller. In this case, the spoiler angles on both sides are the same, that is, the position of the swivel pin is still on the center line of the anti-ice and snow controller. Both embodiments are covered by the present invention and can be set according to actual conditions.

[0069] An embodiment of the present invention provides an anti-ice and snow spoiler device, which includes a spoiler and a deflection mechanism, and the deflection mechanism includes an anti-ice and snow controller and a telescopic component; the spoiler is arranged on both sides of the central symmetry line of the anti-ice and snow controller, and the spoilers on both sides are connected by a rotating pin shaft at the central symmetry line; the end of the spoiler away from the rotating pin shaft is respectively connected to the telescopic component through a first rotating connection component; the telescopic component is respectively connected to both sides of the anti-ice and snow controller through a second rotating connection component. The device uses a rotatable spoiler and a deflection mechanism that adjusts the spoiler angle in real time according to the current operating conditions of the train. It continuously, in real time and quickly adjusts the spoiler to the optimal spoiler angle according to the actual operating conditions of the high-altitude and cold-weather train (operating speed and snow environment), thereby directing the airflow to pass through both sides of the car body, reducing the impact of the airflow on the bogie, and can effectively change the aerodynamic flow field distribution characteristics of the bogie area. It can effectively alleviate the airflow carrying snow mist and drifting snow into the middle and upper parts of the bogie area, achieving the purpose of reducing snow and ice accumulation in the bogie area, and can effectively reduce brake disc scratches, reduce abnormal brake disc wear, and improve the EMU's own anti-ice and snow ability, ensuring the safety and reliability of the bogie, braking system and even the entire vehicle under different speed levels and different snow thicknesses in high-altitude and cold areas, and improving the snow removal effect.

[0070] Based on the above embodiment, the spoiler includes a spoiler portion and a mounting portion;

[0071] The spoiler is fixed to the lower side of the mounting portion, and the spoiler on one side is connected to both ends of the mounting portion on the same side;

[0072] The spoiler on one side and the mounting portion on the same side, and the spoiler on the other side and the mounting portion on the same side are connected into one piece through a rotary pin shaft.

[0073] For example, an anti-ice and snow controller includes two spoilers, one spoiler includes a spoiler portion and a mounting portion, such as Figure 1 As shown, the spoiler 8 is fixed on the lower side of the mounting portion 9, and the spoiler 8 on one side is connected to both ends of the mounting portion 9 on the same side, forming a shuttle shape. The left and right spoilers 8 are respectively fixed on the lower sides of the left and right mounting portions 9, and the left and right mounting portions 9 are connected into one through the middle rotary pin shaft 5.

[0074] The specific connection relationship of the spoiler provided in this embodiment enables the spoiler to rotate freely around the rotation pin.

[0075] As an embodiment, the spoiler is bounded by the rotary pin, and the spoilers on both sides are involute arc plates;

[0076] The spoiler on one side is connected to both ends of the mounting portion on the same side, and the middle portion protrudes forward and away from the mounting portion.

[0077] Specifically, the spoiler is bounded by a pivot pin, with the two spoilers on either side being involute-shaped curved plates, resulting in a smooth, streamlined curved surface. The ends of the smooth, streamlined curved surfaces of the left and right spoilers protrude forward, projecting horizontally into a parabolic shape. During EMU operation, the streamlined curved spoiler disrupts the airflow, diverting it from the two wings of the spoiler. This reduces the impact of the airflow on the bogie behind the spoiler, thereby reducing the risk of ice and snow being carried into critical bogie areas, reducing ice buildup under the vehicle, and alleviating brake disc scratches.

[0078] Based on the above embodiments, Figure 1 As shown, as an embodiment, the anti-ice and snow controller includes a connecting component, a control component 10 and a valve group 11;

[0079] The valve group 11 is connected to the telescopic component 4 through a pipeline;

[0080] The valve group 11 and the control component 10 are both fixed to the connecting component;

[0081] The valve group 11 is used to open the spoiler angle.

[0082] The valve group 11 and the control component 10 are fixed to the connecting component. The valve group 11 is connected to the telescopic component 4 through a pipeline. Specifically, the valve group 11 is connected to the telescopic component 4 through a pipeline and the second rotating connecting component 7 .

[0083] The control component controls the opening and closing of the valve group and the movement of the telescopic component to adjust the opening, thereby adjusting the angle between the spoilers, so as to realize the actual operating conditions of the high-altitude and cold-weather train (operating speed and snow environment) to continuously, in real time and quickly adjust the spoilers to work at the optimal spoiler angle.

[0084] As an embodiment, the telescopic component is a cylinder component, and the number of the cylinder components is the same as the number of the first rotating connection components and the second rotating connection components.

[0085] It is understandable that the telescopic component is a cylinder component that can extend and retract to achieve flexible sliding and reduce wear. Figure 1 As shown, the number of the cylinder components is the same as the number of the first rotating connection components and the second rotating connection components.

[0086] In addition to the cylinder component, a spring component can also be used. However, the spring forces on both sides of the spoiler are the same. Compared with the spring component, the cylinder component is more practical and less prone to wear.

[0087] As an embodiment, the first rotating connection component may be different from or the same as the second rotating connection component. In the same case, both the first rotating connection component and the second rotating connection component are pin components.

[0088] The pin component provided in this embodiment serves to connect the movable components.

[0089] Figure 2 A structural diagram of a train vehicle provided by an embodiment of the present invention, such as Figure 2 As shown, the device includes the above-mentioned anti-ice and snow spoiler device, a bogie 12 and an equipment cabin bottom plate;

[0090] The anti-ice and snow spoiler device is installed on the bottom plate of the equipment compartment of the train vehicle and is close to the bogie 12.

[0091] Specifically, Figure 3 A structural diagram of a front view of a train vehicle provided by an embodiment of the present invention, such as Figure 3 As shown, the anti-ice and snow spoiler 13 is installed on the equipment compartment floor 14 of the high-cold EMU near the bogie 12. The front end is connected and fastened to the car body underframe near the bogie via a swivel pin. The left and right mounting parts can rotate around the swivel pin. The rear end is fastened to the car body underframe near the bogie via two left and right oil cylinders and connecting components via pins.

[0092] Figure 4 A flowchart of an anti-ice and snow spoiler control method provided by an embodiment of the present invention is shown in FIG. Figure 4 As shown, the method includes:

[0093] S11: Obtain the current operating condition information of the train;

[0094] S12: Determine the corresponding spoiler angle according to the current working condition information;

[0095] S13: Determine the second rotating connection component to open a corresponding angle according to the spoiler angle to pull the telescopic component and control the spoiler to perform ice and snow protection operation.

[0096] Specifically, the system obtains the train's current operating condition information, including at least train speed and environmental parameters. It also collects real-time route information, vehicle speed, snow or fog concentration, and speed information. Based on this current operating condition information, the system determines the corresponding spoiler angle. The spoiler accuracy is determined by matching the current operating condition information to the optimal angle. Simultaneously, the opening and closing of the control valve group are controlled based on the optimal angle to adjust the movement of the telescopic component, causing the anti-ice and snow spoiler to continuously deflect to the preset spoiler angle for anti-ice and snow operation.

[0097] An embodiment of the present invention provides an anti-ice and snow spoiler control method, which uses a rotatable spoiler and a deflection mechanism that adjusts the spoiler angle in real time according to the current operating condition information of the train. The spoiler is continuously, in real time, and quickly adjusted to operate at an optimal spoiler angle according to the actual operating conditions of the high-altitude and cold-weather train (operating speed and snow environment), thereby guiding the airflow to pass through both sides of the car body, reducing the impact of the airflow on the bogie, and can effectively change the aerodynamic flow field distribution characteristics of the bogie area. It can effectively alleviate the airflow from carrying snow fog and drifting snow into the middle and upper parts of the bogie area, achieving the purpose of reducing snow and ice accumulation in the bogie area, and can effectively reduce brake disc scratches, reduce abnormal brake disc wear, and improve the anti-ice and snow ability of the EMU itself, ensuring the safety and reliability of the bogie, braking system and even the entire vehicle under different speed levels, different snow thicknesses and other operating conditions in high-altitude and cold areas, and improving the snow removal effect.

[0098] Based on the above embodiment, determining the corresponding spoiler angle according to the current working condition information in step S12 includes:

[0099] Obtaining the train running speed and environmental information parameters corresponding to the current operating condition information, wherein the environmental information parameters include at least a snow thickness parameter and a snow density parameter on the train track;

[0100] Determine the current operating condition level based on the train running speed and environmental information parameters;

[0101] According to the mapping relationship between each operating condition level and the spoiler combination, the target spoiler angle corresponding to the current operating condition level is determined as the spoiler angle.

[0102] Specifically, the current operating condition level is determined according to the train running speed and environmental information parameters, and the target spoiler angle corresponding to the current operating condition level is determined as the current spoiler angle according to the mapping relationship between the operating condition level and the spoiler combination.

[0103] As an embodiment, the process of determining the mapping relationship between the current operating condition level and the spoiler combination includes:

[0104] Presetting various arc surface shape parameters, various preset operating speeds, and various preset environmental information parameters of the spoiler, wherein the arc surface shape parameters include at least an arc angle and an arc surface length;

[0105] Based on the cambered surface parameters, preset operating speeds, and preset environmental information parameters, the spoiler combination angles under each operating condition level are determined through simulation calculations and wind tunnel test methods to establish a mapping relationship between each operating condition level and the spoiler combination.

[0106] Specifically, based on the design and installation configuration of high-altitude cold-weather EMUs equipped with anti-ice and snow spoilers, numerical simulations of wind and snow flows and wind tunnel testing were conducted to determine the optimal combined angles of the left and right spoilers for different combinations of vehicle speed, track snow thickness, and snow density. A table of optimal spoiler angle combinations was then developed. Numerical simulations of wind and snow flows and wind tunnel testing were also conducted to determine the optimal spoiler angle combinations for each combination of speed level and snow conditions.

[0107] The optimal combination angle matching table for different speed levels and snow conditions is stored in the controller. The controller collects real-time vehicle speed, track snow thickness, and snow density, and determines the optimal combination angle of the left and right spoilers corresponding to the vehicle's current working conditions based on the optimal combination angle matching table, and issues the optimal angle control command to the valve group.

[0108] The valve group receives the optimal angle control instruction, controls the movement of the left and right drive cylinders, and causes the left and right mounting parts of the active anti-ice and snow spoiler device to continuously deflect to the set angle.

[0109] It should be noted that the deflection process can be deflected little by little based on the deflection step length, or can be deflected into place in one step, which can be set according to actual conditions.

[0110] As an embodiment, after determining the current operating condition level according to the train running speed and environmental information parameters, the method further includes:

[0111] When the current operating condition level is less than or equal to a preset operating condition level, a preset spoiler angle is obtained, wherein the preset operating condition level indicates that the train does not need anti-ice and snow control;

[0112] The telescopic component is controlled to deflect according to the preset spoiler angle, and the anti-ice and snow spoiler device is turned off.

[0113] Specifically, when the current operating condition level is less than or equal to the preset operating condition level, it indicates that the anti-ice and snow spoiler device is not currently activated, or does not pose a threat to train safety. Therefore, a preset spoiler angle can be obtained. In this embodiment, the preset spoiler angle is less than the minimum spoiler angle when the device is activated.

[0114] The telescopic component is controlled to deflect according to the preset spoiler angle, and the anti-ice and snow spoiler device is turned off. According to the actual anti-ice and snow needs, the controller is automatically or manually started or stopped, and the left and right mounting parts are kept fixed at the optimal set angle.

[0115] Figure 5 A schematic diagram of a train system provided by an embodiment of the present invention is shown in FIG. Figure 5 As shown, the train set within the train system includes a start / stop switch 101, a signaling system 105, a control system 106, and a power supply system 107. The anti-ice and snow spoiler device includes a spoiler 1 and a deflection mechanism 2. The deflection mechanism 2 includes a valve block 11, a telescopic component 14, a connecting component, and an anti-ice and snow controller 3. In this embodiment, the deflection mechanism 2 and the anti-ice and snow controller 3 are separated because the spoiler angle adjustment within the train system is based on the anti-ice and snow controller 3 receiving start / stop signals from various systems within the train set, line snow accumulation information, train speed information, and power supply.
