Description

Technical Field

[0001] The present disclosure relates to the technical field of rail vehicles, and in particular to an ice melting system, an ice melting method, and a rail vehicle. Background Art

[0002] The third rail, also known as the power rail, is a separate rail installed alongside urban rail lines (such as subways and light rail) for power supply. Working in conjunction with a current collector (collector shoe), the third rail provides power to all equipment on rail transit trains. Third rail power supply is widely adopted due to its advantages, such as minimal impact on the urban landscape, ease of maintenance, and low installation costs.

[0003] However, in some areas, due to winter snowfall, rainfall and other reasons, ice is easily formed on the third rail due to the cold weather, resulting in the third rail being unable to effectively contact the collector shoe, affecting vehicle driving safety. Summary of the Invention

[0004] In view of this, the present disclosure provides an ice melting system, an ice melting method and a rail vehicle, which can effectively remove ice on the third rail and prevent the third rail from being corroded by ice melting liquid.

[0005] One aspect of the present disclosure provides an ice-melting system installed in a rail vehicle, the ice-melting system comprising a first container, a second container, a guide pipe, and a controller. The first container contains ice-melting liquid, and the second container contains cleaning liquid. The guide pipe is connected to the first and second containers and is adapted to guide the ice-melting liquid or the cleaning liquid to both sides of the rail vehicle's travel direction. The controller is configured to, during operation of the rail vehicle, if ice forms on the third rail, direct the ice-melting liquid through the guide pipe to the third rail to remove the ice; and, if it is determined that the third rail has ice-melting liquid sprayed by the previous ice-melting system and the ambient temperature is above the freezing temperature, direct the cleaning liquid through the guide pipe to the third rail to remove the ice.

[0006] According to an embodiment of the present disclosure, the controller includes an information acquisition module and an identification module. The information acquisition module is configured to obtain the location information of the rail vehicle from a vehicle control center and to determine whether de-icing fluid is present on the third rail from the vehicle control center. The identification module is configured to determine the relative position of the third rail relative to the rail vehicle based on the location information, thereby driving a collector shoe corresponding to the third rail from among a plurality of collector shoes to extend and contact the third rail, thereby transmitting electrical energy to the rail vehicle.

[0007] According to an embodiment of the present disclosure, the guide pipe includes a first pipe, a second pipe, a third pipe, and multiple fourth pipes. The first pipe is connected to the first container, the second pipe is connected to the second container, and one end of the third pipe is connected to the first and second pipes. One end of the multiple fourth pipes is connected to the other end of the third pipe, and the other ends of the multiple fourth pipes extend to the multiple collector shoes, thereby draining the ice melting liquid or the cleaning liquid through the collector shoes and onto the third rail.

[0008] According to an embodiment of the present disclosure, the ice melting system further includes a plurality of valves, each mounted on the plurality of fourth pipes. The controller is configured to, based on the relative positions, open the valves on the fourth pipes on the collector shoe corresponding to the third rail, thereby diverting the ice melting liquid or cleaning fluid in the fourth pipes to the third rail.

[0009] According to an embodiment of the present disclosure, the ice melting system further includes a pump body mounted on the third pipe. The controller is configured to obtain the operating speed of the rail vehicle from the vehicle control center and determine the flow rate of the ice melting liquid or the cleaning fluid pumped by the pump body based on the operating speed.

[0010] According to an embodiment of the present disclosure, there are multiple first containers and multiple second containers, and a liquid level sensor is respectively provided in each of the first container and the second container; wherein, the controller is configured to switch to the other of the first containers to provide the ice-melting liquid and switch to the other of the second containers to provide the cleaning liquid when the ice-melting liquid in the current first container and the cleaning liquid in one of the second containers are at low liquid levels, so as to reduce the shutdown time of the ice-melting system due to low liquid levels and issue a prompt signal.

[0011] According to an embodiment of the present disclosure, the ice melting system further includes ultrasonic sensors installed on both sides of the rail vehicle in its travel direction, configured to emit ultrasonic pulses and receive pulses reflected by the third rail. The controller is configured to determine whether ice is formed on the third rail based on intensity and temporal variations of the ultrasonic pulses and the received pulses.

[0012] According to an embodiment of the present disclosure, the de-icing system further includes a temperature sensor mounted on an outer wall of the rail vehicle. The controller is configured to obtain temperature data from the temperature sensor to determine the ambient temperature. If it is determined that de-icing fluid previously sprayed by the de-icing system is present on the third rail and the ambient temperature is higher than the freezing temperature of the cleaning fluid, the controller sprays the cleaning fluid onto the third rail to prevent the cleaning fluid from freezing.

[0013] As another aspect of the embodiments of the present disclosure, an ice melting method is provided, which is applied to any of the above-mentioned ice melting systems. The ice melting method includes:

[0014] Acquiring position information of the rail vehicle, and acquiring a relative position of the third rail relative to the rail vehicle based on the position information;

[0015] According to the relative position, driving the collector shoe corresponding to the third rail to contact the third rail;

[0016] In the case of ice forming on the third rail, guiding the ice melting liquid through the guide pipe and following the collector shoe to the third rail to remove the ice on the third rail; and

[0017] When it is determined that there is de-icing liquid on the third rail and the ambient temperature is higher than the freezing temperature, the cleaning liquid is guided to the third rail through the guide pipe along the collector shoe to remove the de-icing liquid sprayed on the third rail by the previous de-icing system.

[0018] As another aspect of the embodiments of the present disclosure, a rail vehicle is provided, comprising any one of the above-mentioned ice melting systems.

[0019] According to the de-icing system of the embodiment of the present disclosure, when ice forms on the third rail, de-icing liquid is directed to the third rail through a guide pipe to remove ice from the third rail. When it is determined that de-icing liquid sprayed by the previous de-icing system is on the third rail and the ambient temperature is higher than the freezing temperature, cleaning liquid is directed to the third rail through the guide pipe to remove the de-icing liquid from the third rail. This prevents the de-icing liquid from corroding the third rail and prevents the cleaning liquid from condensing into ice again on the third rail, thereby ensuring the driving safety of rail vehicles.

Figure 2 Schematically shows a side view of an ice melting system according to some embodiments of the present disclosure, Figure 3 A top view of an ice melting system according to some other embodiments of the present disclosure is schematically shown.

[0046] As one aspect of the embodiments of the present disclosure, an ice melting system 1 is provided. Figures 1 to 3 As shown, an ice-melting system 1 is installed in a rail vehicle 2 and includes a first container 11, a second container 12, a guide pipe 13, and a controller 14. The first container 11 contains ice-melting liquid, and the second container 12 contains cleaning liquid. The guide pipe 13 communicates with the first and second containers 11, 12 and is adapted to direct the ice-melting liquid or cleaning liquid to both sides of the rail vehicle 2 in its travel direction. During operation of the rail vehicle 2, if ice forms on the third rail, the controller 14 is configured to direct the ice-melting liquid through the guide pipe 13 to the third rail to remove the ice. Furthermore, if ice-melting liquid previously sprayed by the ice-melting system 1 is determined to be on the third rail and the ambient temperature is above the freezing temperature, the controller 14 is configured to direct the cleaning liquid through the guide pipe 13 to the third rail to remove the ice.

[0047] According to the ice melting system 1 of the embodiment of the present disclosure, when ice forms on the third rail, ice melting liquid is directed to the third rail through the guide pipe 13 to remove ice from the third rail. When it is determined that ice melting liquid previously sprayed by the ice melting system 1 is on the third rail and the ambient temperature is higher than the freezing temperature, cleaning liquid is directed to the third rail through the guide pipe 13 to remove the ice melting liquid from the third rail, thereby preventing the ice melting liquid from corroding the third rail and preventing the cleaning liquid from condensing into ice again on the third rail, thereby ensuring the driving safety of the rail vehicle 2.

[0048] According to an embodiment of the present disclosure, the rail vehicle includes a subway or a light rail.

[0049] According to the embodiments of the present disclosure, Figure 1 As shown, the third rail, also known as the contact rail, is an additional conductive rail laid along the track line and parallel to the track.

[0050] According to the embodiment of the present disclosure, the traction power supply mode of the rail vehicle 2 is third rail power supply, and the current collecting device is a collecting shoe.

[0051] According to the disclosed embodiment, the power shoe is mounted on both sides of the vehicle bogie 22, near the center of the vehicle's outer side. The power shoe is lowered when in use and stowed when not in use. The mounting bracket for each power shoe is fixed to the underside of the bogie frame with multiple bolts.

[0052] According to the embodiments of the present disclosure, Figure 1 As shown, the rail vehicle 2 includes a leading car and a trailing car located at both ends of the vehicle in the longitudinal direction, and an intermediate car located between the leading car and the trailing car. It is understood that the leading car and the trailing car are relative to the running direction of the rail vehicle 2. When the rail vehicle 2 reverses direction, the trailing car serves as the leading car and the leading car serves as the trailing car.

[0053] In an illustrative embodiment, Figure 1 As shown, the first container 11 and the second container 12 of the ice melting system 1 can be installed in the driver's cab of the leading vehicle or the trailing vehicle. It is understood that the ice melting system 1 can be installed in the middle vehicle, for example, under the seat.

[0054] According to an embodiment of the present disclosure, the cleaning fluid may include a neutral cleaning fluid, such as water. The de-icing fluid is a liquid used to melt or prevent ice from forming, and may include a salt de-icing fluid, an acid de-icing fluid, or a composite de-icing fluid.

[0055] Figure 4 The block diagram of the controller according to the embodiment of the present disclosure is schematically shown.

[0056] According to the embodiments of the present disclosure, Figure 4 As shown, the controller 14 includes an information acquisition module 141 and an identification module 142. The information acquisition module 141 is configured to obtain the location information of the rail vehicle 2 from the vehicle control center and to determine whether de-icing liquid is present on the third rail. The identification module 142 is configured to determine the relative position of the third rail relative to the rail vehicle 2 based on the location information, thereby driving the collector shoe 21 corresponding to the third rail (e.g., the closest collector shoe 21) to extend and contact the third rail, thereby transmitting electrical energy to the rail vehicle 2.

[0057] According to an embodiment of the present disclosure, a plurality of collector shoes 21 are telescopically installed on both sides of the rail vehicle 2 for contacting the third rail to transmit electrical energy to the rail vehicle 2 .

[0058] According to the embodiment of the present disclosure, the vehicle control center can obtain the position information, speed information, spraying information of the de-icing liquid system and other road spectrum information of each rail vehicle 2.

[0059] According to an embodiment of the present disclosure, the controller 14 controls the ice melting system 1 based on the road spectrum information obtained from the control center. When it is determined that ice is formed on the third rail, the ice on the third rail is removed by spraying ice melting liquid. When the vehicle enters a tunnel or a non-icing section, the operation of the ice melting system 1 is avoided to avoid wasting ice melting liquid.

[0060] The ice-melting system 1 provided by the disclosed embodiment can effectively melt ice from the third rail in heavy snow, ensuring the safe operation of a rail vehicle 2. Furthermore, the system is highly portable, with an interface provided on the vehicle side, eliminating the need for dedicated vehicle space. During non-ice-melting periods (e.g., summer), the first and second containers 11, 12 can be removed and moved under the vehicle.

[0061] According to an embodiment of the present disclosure, the guide pipe 13 includes a first pipe 131, a second pipe 132, a third pipe 133, and a plurality of fourth pipes 134. The first pipe 131 is in communication with the first container 11, the second pipe 132 is in communication with the second container 12, one end of the third pipe 133 is in communication with the first and second pipes 131, 132, and one end of the plurality of fourth pipes 134 is in communication with the other end of the third pipe 133. The other ends of the plurality of fourth pipes 134 extend to the plurality of collector shoes 21, respectively, to guide the de-icing liquid or cleaning liquid through the collector shoes 21 and onto the third rail.

[0062] According to an embodiment of the present disclosure, the controller 14 determines the relative position of the third rail with respect to the rail vehicle 2 based on the current position information of the rail vehicle 2, determines whether the third rail is on the left or right side of the running direction of the rail vehicle 2, and then drives the collector shoe 21 adjacent to the third rail among the multiple collector shoes 21 to extend, and by opening the fourth pipe 134 corresponding to the extended collector shoe 21, the de-icing liquid or the cleaning liquid is guided through the collector shoe 21 to the third rail, thereby completing the cleaning or de-icing.

[0063] According to an embodiment of the present disclosure, first pipe 131 communicates with first container 11 for transporting de-icing liquid from first container 11. Second pipe 132 communicates with second container 12 for transporting cleaning liquid from second container 12. Third pipe 133 serves as a main pipeline, connecting first pipe 131 and second pipe 132, and selectively transporting either cleaning liquid or de-icing liquid as needed. Fourth pipe 134 serves as a branch pipeline, connected to third pipe 133, for distributing cleaning liquid or de-icing liquid to different destinations.

[0064] According to an embodiment of the present disclosure, the ice-melting system 1 further includes a plurality of valves, each of which is installed on a plurality of fourth pipes 134. The controller 14 is configured to open the valves on the fourth pipes 134 on the collector shoe 21 corresponding to the third rail based on their relative positions, thereby diverting the ice-melting liquid or cleaning fluid in the fourth pipes 134 to the third rail.

[0065] According to an embodiment of the present disclosure, the ice melting system 1 further includes a first valve and a second valve. The first valve is installed on the first pipe 131 , and the second valve is installed on the second pipe 132 .

[0066] During the implementation of the present disclosure, it was discovered that the de-icing device in the related art outputs the same de-icing liquid flow rate at different speeds of the rail vehicle 2. Therefore, when the speed of the rail vehicle 2 is low, the output flow rate of the de-icing liquid is excessively large, resulting in waste. On the other hand, when the speed is high, the output flow rate of the de-icing liquid is too small, resulting in a poor de-icing effect.

[0067] According to an embodiment of the present disclosure, the ice melting system 1 further includes a pump body, which is mounted on the third pipe 133. The controller 14 is configured to obtain the operating speed of the rail vehicle 2 from the vehicle control center and determine the flow rate of the ice melting liquid or cleaning fluid pumped by the pump body based on the operating speed.

[0068] According to an embodiment of the present disclosure, the controller 14 can obtain the real-time operating speed of the rail vehicle 2 from the vehicle control center to adjust the flow rate of the ice-melting liquid or cleaning liquid pumped by the pump body according to the real-time operating speed. When the operating speed is fast, the pumping flow rate is large, and when the operating speed is slow, the pumping flow rate is small, thereby improving the ice melting or cleaning effect when the operating speed is fast, and avoiding the waste of ice-melting liquid or cleaning liquid when the operating speed is slow.

[0069] According to an embodiment of the present disclosure, there are multiple first containers 11 and second containers 12, each of which is provided with a liquid level sensor. The controller 14 is configured to switch to supplying the ice-melting liquid from the other of the first containers 11 and the cleaning liquid from the other of the second containers 12 if the current ice-melting liquid in the first container 11 or the cleaning liquid in one of the second containers 12 is at a low liquid level, thereby reducing the downtime of the ice-melting system 1 due to low liquid levels and issuing a warning signal.

[0070] According to an embodiment of the present disclosure, the liquid level sensor may be a float switch.

[0071] According to an embodiment of the present disclosure, the prompt signal includes a prompt to replenish cleaning fluid or replenish ice-melting fluid.

[0072] According to an embodiment of the present disclosure, the number of the first containers 11 may include any one of 1, 2, 3, 4, 6, etc.

[0073] According to an embodiment of the present disclosure, the number of the second containers 12 may include any one of 1, 2, 4, 5, 6, etc.

[0074] According to an embodiment of the present disclosure, a plurality of first containers 11 and a plurality of second containers 12 may be stacked or installed in parallel in the rail vehicle 2 .

[0075] In an exemplary embodiment, when the level of ice-melting liquid in the current first container 11 is low, the controller 14 checks the level of ice-melting liquid in a second first container 11 adjacent to the first first container 11. If the ice-melting liquid in the second first container 11 is at a normal level, the second first container 11 is used to supply ice-melting liquid, and a low-level prompt signal is issued to remind the staff to refill the first first container 11. If the ice-melting liquid in all first containers 11 is at a low level, the supply of ice-melting liquid is stopped to prevent the pump from idling and causing damage.

[0076] According to the embodiments of the present disclosure, by providing multiple first containers 11 and multiple second containers 12, the downtime of the ice-melting system 1 due to low liquid levels can be effectively reduced, and a continuous supply of cleaning fluid and ice-melting fluid can be ensured. Furthermore, the automatic switching and alarm functions of the ice-melting system 1 improve operational convenience and system reliability.

[0077] According to an embodiment of the present disclosure, ice melting system 1 further includes ultrasonic sensors mounted on both sides of rail vehicle 2 in the direction of travel. The ultrasonic sensors are configured to transmit ultrasonic pulses and receive pulses reflected by the third rail. Controller 14 is configured to determine whether ice is formed on the third rail based on the intensity and time variations of the ultrasonic pulses and the received pulses.

[0078] According to embodiments of the present disclosure, ice and the third rail's material have different acoustic properties, so ice formation can cause changes in the intensity and duration of ultrasonic wave reflections. By analyzing these changes, controller 14 can determine whether ice is present on the third rail and potentially measure its thickness.

[0079] According to an embodiment of the present disclosure, an ultrasonic sensor is provided to detect the third rail. The controller 14 can determine whether ice is formed on the third rail based on the ultrasonic pulse and the received pulse, and can then control the ice melting system 1 after the vehicle enters a tunnel or a non-icing section to avoid waste of ice melting liquid caused by the operation of the ice melting system 1.

[0080] According to the de-icing system 1 provided in the embodiments of the present disclosure, an ultrasonic sensor installed on the line side can provide controller 14 with third rail icing information. Controller 14 integrates icing information, vehicle speed, third rail power receiving position, and vehicle location information to intelligently control the spraying of de-icing liquid and its speed. After de-icing, it cleans the third rail and other equipment to prevent corrosion.

[0081] According to an embodiment of the present disclosure, the ice melting system 1 further includes a temperature sensor mounted on an outer wall of the rail vehicle 2. The controller 14 is configured to obtain temperature data from the temperature sensor to obtain the ambient temperature. If it is determined that the third rail has ice melting liquid sprayed by the ice melting system 1 and the ambient temperature is higher than the freezing temperature of the washer fluid, the controller 14 sprays the washer fluid onto the third rail having the ice melting liquid to prevent the washer fluid from freezing.

[0082] According to the embodiment of the present disclosure, the third rail can be cleaned multiple times by multiple rail vehicles 2 according to actual needs to avoid corrosion caused by residual ice melting liquid on the third rail and the collector shoe 21. For example, the third rail can be cleaned by the next rail vehicle 2 or even the next day.

[0083] Figure 5 The flowchart of the ice melting method according to the embodiment of the present disclosure is schematically shown.

[0084] As another aspect of the embodiments of the present disclosure, an ice melting method is provided, which is applied to any of the above-mentioned ice melting systems 1, such as Figure 5 As shown, the ice melting method includes operations S510 to S540.

[0085] In operation S510 , position information of a rail vehicle is acquired, and a relative position of the third rail with respect to the rail vehicle is acquired based on the position information.

[0086] In operation S520, a collector shoe corresponding to the third rail is driven to contact the third rail according to the relative position.

[0087] In operation S530 , when ice is formed on the third rail, ice-melting liquid is guided to the third rail through the guide pipe following the collector shoe to remove ice from the third rail.

[0088] In operation S540 , if it is determined that there is deicing liquid on the third rail and the ambient temperature is higher than the freezing temperature, cleaning liquid is guided to the third rail through the guide pipe following the collector shoe to remove the deicing liquid sprayed on the third rail by the previous deicing system.

[0089] According to the de-icing method of the embodiment of the present disclosure, when ice forms on the third rail, de-icing liquid is directed to the third rail through a guide pipe to remove ice from the third rail. When it is determined that de-icing liquid sprayed by a previous de-icing system is on the third rail and the ambient temperature is higher than the freezing temperature, cleaning liquid is directed to the third rail through the guide pipe to remove the de-icing liquid from the third rail, thereby preventing the de-icing liquid from corroding the third rail and preventing the cleaning liquid from re-condensing into ice on the third rail, thereby ensuring the driving safety of rail vehicles.

[0090] As another aspect of the embodiments of the present disclosure, a rail vehicle 2 is provided, comprising any one of the above-mentioned ice melting systems 1 .

[0091] According to an embodiment of the present disclosure, the first container 11 and the second container 12 of the ice melting system 1 are installed in the rail vehicle 2 for easy disassembly and heat preservation.

[0092] According to the embodiment of the present disclosure, a guide pipe 13, an electrical interface, and a network interface can be set on the driver's cab side of the vehicle. When ice melting is required in heavy snow weather, the first container 11 and the second container 12 are moved to the vehicle, and the pump body is connected to the electrical, pipe interface, and network interface on the vehicle end. During the operation of the vehicle, the ice-melting liquid system is turned on to spray the ice-melting liquid onto the third rail to melt the ice. After the ice melting is completed, the equipment is cleaned with cleaning fluid to prevent equipment corrosion.

[0093] The embodiments of the present disclosure are described above. However, these embodiments are for illustrative purposes only and are not intended to limit the scope of the present disclosure. Although each embodiment has been described separately above, this does not mean that the measures in each embodiment cannot be used in combination to advantage.
