Description

Technical Field

[0002] During the long winter with extremely cold and snowy weather, not only the maintenance operation order is disturbed, but also serious potential safety hazards are brought to the operation safety of multiple units and the equipment quality. At present, during the operation of high-speed trains, they may be affected by adverse weather such as extreme low temperature, snowfall, and freezing rain. When a high-speed train runs on a snow-covered section, snow grains will instantaneously melt on the surface of high-temperature components such as brake discs, forming a large amount of snowmelt water in the bogie area. Subsequently, under the action of the train wind, it splashes and forms an ice and snow covering layer more than 10 centimeters thick on the bogie, directly affecting the braking and steering of the bogie and seriously affecting the operation safety of the train, leaving a huge potential safety hazard for railway operation safety.

[0003] With the continuous construction of high-speed railway operation routes, the number of high-speed trains running in cold regions and other ultra-low temperature regions is increasing day by day. Under some working conditions, high-speed trains have a long single running time and a long running mileage and do not have the working conditions for de-icing with a long-time stop. Existing de-icing technologies, such as manual mechanical de-icing, thermal de-icing and other methods, all require operation when the train stops and enters the depot. Therefore, high-speed trains need a device that can de-ice the bogie in real time without stopping. Summary of the Utility Model

[0030] To make the technical problems, technical solutions, and advantages to be solved by the present utility model clearer, the following will be described in detail with reference to the attached drawings and specific embodiments.

[0031] As described in the background art, generally, the bogie B is arranged in the bogie compartment of a high-speed train. The bogie B is fixedly connected between its upper bolster and the top wall of the high-speed train bogie compartment. When the melted ice and water encounter a low-temperature environment, a layer of ice will form between the top wall of the bogie compartment and the bogie B under the action of the train wind. This layer of ice solidifies between the bogie B and the top wall of the bogie compartment, resulting in the bogie B being unable to perform its normal functions. The purpose of this application is to de-ice this layer of ice in real time during the operation of the train.

[0032] As Figures 1-4 shown, an embodiment of the present utility model provides a de-icing unit. The de-icing unit A includes an upper plate 1, a lower plate 2, and an electromagnetic coil 3. Among them, the upper plate 1 and the lower plate 2 are arranged along the vertical direction of the high-speed train. An electromagnetic coil 3 is also arranged between the upper plate 1 and the lower plate 2, and the electromagnetic coil 3 is fixed on the lower plate 2. At the same time, the lower plate 2 is fixed on the bogie B. When the electromagnetic coil 3 is connected to high-frequency direct current, a magnetic field is generated when the high-frequency direct current passes through the electromagnetic coil 3. Eddy currents are generated when the magnetic field passes through the upper plate 1 and the lower plate 2. Since the upper plate 1 and the lower plate 2 are made of metal materials, a large amount of Joule heat can be generated by the upper plate 1 and the lower plate 2, so as to quickly heat up and conduct heat to the ice layer above the bogie B, melting the ice layer and achieving the purpose of de-icing. This de-icing operation can be carried out when the high-speed train is running or in a parked state, with higher de-icing efficiency and applicable conditions.

[0033] Furthermore, the de-icing unit A further includes a thickness detector 4 and a temperature detector 5. The thickness detector 4 is used to detect the thickness of the ice layer attached above the bogie B, and the temperature detector 5 is used to detect the temperature of the upper plate 1.

[0034] When the thickness detector 4 detects that the ice layer thickness reaches the preset maximum thickness, the electromagnetic coil 3 is energized, and the upper plate 1 melts and de-ices the ice layer. When the temperature detector 5 detects that the upper plate 1 reaches the preset temperature, the electromagnetic coil 3 is de-energized. At this time, the ice layer on the bogie B has begun to melt and fall off. The temperature monitoring of the upper plate by the temperature detector 5 can effectively avoid excessive consumption of electric energy and protect the electromagnetic coil 3.

[0035] Preferably, the thickness detector 4 is one of an infrared detection sensor and an ultrasonic sensor.

[0036] Preferably, the temperature detector 5 is a temperature sensor.

[0037] Furthermore, to ensure that the lower plate 2 is firmly fixed to the bogie B during driving, the lower plate 2 is detachably arranged on the bogie B, and a detection module 6 for judging whether the lower plate 2 is firmly connected to the bogie B is arranged between the bogie B and the lower plate 2.

[0038] In this embodiment, the lower plate 2 is adhesively bonded to the bogie B by a high-temperature resistant adhesive material. At the same time, a pressure sensor is arranged between the bogie B and the lower plate 2 as the detection module 6. When the lower plate 2 is firmly adhesively bonded to the bogie B, the reading of the pressure sensor is stable, while when the lower plate 2 becomes loose or falls off, the reading of the pressure sensor is distorted, thereby judging that the lower plate 2 becomes loose or falls off.

[0039] During the driving of the high-speed train, since the wheelset of the bogie B is always in contact with the rail and rotates, the wheelset will generate a certain amount of heat. Therefore, the heat generated by the lower plate 2 under the action of the electromagnetic coil 3 is not only wasted, but also affects the performance of the wheelset. Therefore, it is necessary to reduce the heat generation of the lower plate 2.

[0040] In this application, a plurality of magnetic strips 7 are fixed on the upper surface of the lower plate 2. The magnetic strips 7 are permanent magnets and the electromagnetic coil 3 is located above the magnetic strips 7. The magnetic pole direction of the magnetic strips 7 is parallel to the magnetic pole direction generated by the electromagnetic coil 3 and the magnetic poles of the magnetic strips 7 are the same as the magnetic pole direction generated by the electromagnetic coil 3. Under the guidance of the magnetic strips 7, the combined magnetic field generated by the electromagnetic coil 3 and the magnetic strips 7 is unidirectionally upward, causing the upper plate 1 to generate heat and avoiding excessive useless heat generation of the lower plate 2.

[0041] Preferably, in this application, the upper plate 1 is an iron plate and the lower plate 2 is an aluminum plate. Due to the weak eddy current characteristic of the aluminum material, in the combined magnetic field, the heat generated by the lower plate 2 will be less than that of the upper plate 1. And the iron material has a small resistance and can generate a strong eddy current under a low electromotive force, so that the iron material upper plate 1 generates a large amount of Joule heat to achieve rapid heating.

[0042] A connecting component 8 is also provided between the upper layer plate 1 and the lower layer plate 2. The connecting component 8 can adjust the distance between the upper layer plate 1 and the lower layer plate 2 in the vertical direction to adjust the amount of heat generated by the upper layer plate 1 during electromagnetic induction, avoiding overheating caused by long-term operation and damaging the de-icing unit A.

[0043] Preferably, the connecting component 8 includes a screw 81. The screw 81 passes through the upper layer plate 1, and the lower end of the screw 81 passes through the lower layer plate 2 and is screwed with a nut 82. A side plate is also detachably provided between the upper layer plate 1 and the lower layer plate 2.

[0044] The present application also provides a de-icing assembly, including the aforementioned de-icing unit A. One or more de-icing units A are provided, and each de-icing unit A is arranged on the bogie B. The de-icing assembly further includes a high-frequency DC power supply and a controller. The DC power supply is electrically connected to each de-icing unit A to supply power to the de-icing unit A. When there are multiple de-icing units A, each de-icing unit A is connected in series, so that the de-icing unit A can perform regional de-icing in the area where the de-icing unit A is located.

[0045] The aforementioned controller controls the on-off of the circuit between several de-icing units A and the DC power supply through the signals of the temperature detector 5 and the thickness detector 4 of any one de-icing unit A.

[0046] Specifically, when there are multiple de-icing units A, the controller obtains the ice layer thickness of the installation area of the de-icing assembly through the thickness detection signal of any one de-icing unit A. When any thickness detector 4 detects that the ice layer thickness reaches the preset maximum thickness, the controller controls the electrical connection between the DC power supply and the de-icing unit A in this area, and starts to heat and de-ice the upper layer plate 1. As the de-icing progresses, the temperature detector 5 continuously obtains the temperature of the corresponding upper layer plate 1. After any upper layer plate 1 reaches the preset temperature, the temperature detector 5 feeds back the signal to the controller, and the controller controls the de-icing unit A to be disconnected from the DC power supply. An electromagnetic switch is provided on the circuit between the DC power supply and the de-icing unit A to facilitate the controller to turn the circuit on and off.

[0047] Furthermore, the controller is also signal-connected to the detection module 6 of each de-icing unit A for displaying whether the de-icing unit A is firm. In this embodiment, the controller judges whether the de-icing unit A is firm by displaying the pressure between the lower layer plate 2 and the bogie B.

[0048] In the present application, the de-icing assembly is arranged on the bogie B, and the installation of the de-icing assembly cannot interfere with the normal function of the bogie B. In the present application, the de-icing assembly can be arranged at one or several of the frame, bolster and braking components of the bogie B. At least one group of de-icing assemblies is provided.

[0049] Such as Figure 5The following is an installation schematic diagram of a set of de-icing components on a frame.

[0050] The present application also provides a high-speed train with de-icing components, including the aforementioned de-icing components.

[0051] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle described in the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
