Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, the meanings of "multiple" and "several" are two or more, unless otherwise clearly and specifically defined.

[0032] Please also read Figures 1 to 5, the virtual rail train wind source device provided by the utility model is now described. The virtual rail train wind source device includes a base frame 10, an air compressor 20, a cooling fan 30, an electric control box 40, an air filter 50, a cooler 60, and a dryer 70; wherein, the base frame 10 is used to be mounted on the roof of a train; the air compressor 20 is connected to the base frame 10, and is arranged close to one side of the base frame 10, and the air compressor 20 is used to inhale normal pressure air and compress the normal pressure air at least one level to form high pressure air; the cooling fan 30 is connected to the base frame 10 and is located directly below the air compressor 20, and is used to blow cooling air from bottom to top toward the air compressor 20; the electric control box 40 is connected to the base frame 10 and is electrically connected to the cooling fan 30 and the air compressor 20 respectively, and the electric control box 40 is axially connected to the air compressor 20. The air compressor 20 is aligned and distributed, and the electric control box 40 is used to be electrically connected to the vehicle control system; the air filter 50 is connected to the base frame 10 and is located on the side of the electric control box 40. The air filter 50 is electrically connected to the electric control box 40. The air filter 50 is connected to the normal-pressure air inlet of the air compressor 20 for circulating and filtering normal-pressure air; the cooler 60 is connected to the base frame 10 and is located on the side of the air compressor 20. The cooler 60 is connected to the high-pressure air outlet of the air compressor 20 for circulating and cooling the high-pressure air; the dryer 70 is connected to the base frame 10 and is located between the cooler 60 and the air filter 50. The dryer 70 is connected to the cooler 60 and is connected to the train air unit for drying the high-pressure air and discharging it into the train air unit.

[0033] It should be noted that in the present embodiment, the air compressor 20 preferably adopts an oil-free piston air compressor 20. On the one hand, compared with the oil-injected screw air compressor 20 or the micro-oil vane air compressor 20 commonly used in the wind source device, it not only saves the use of lubricating oil, but also can avoid the problem of lubricating oil emulsification affecting the normal operation of the air compressor 20; on the other hand, the oil-free piston air compressor 20 is small in size and light in weight, which is more conducive to the component integration and compactness of the wind source device.

[0034] In this embodiment, the heat dissipation fan 30 is preferably an axial flow flat fan, which is beneficial to reducing the axial space occupied, thereby facilitating installation below the air compressor 20 and improving the compactness of the structure.

[0035] In this embodiment, a controller is provided in the electric control box 40, and the start and stop of the cooling fan 30 is controlled by the controller; a temperature sensor 24 is provided at the high-pressure air outlet of the air compressor 20, and the temperature sensor 24 is used to detect the outlet temperature of the air compressor 20 and feed back the temperature detection value to the controller and then to the train control system. When the pressure detection value exceeds the threshold, the train control system sends a command to the controller to control the air compressor 20 to stop, thereby avoiding damage due to overheating of the working temperature of the air compressor 20; a pressure difference sensor 52 is provided in the air filter 50, and the pressure difference sensor 52 is used to detect the pressure difference before and after the air filter 50 and transmit the pressure difference detection value to the controller, and then the controller feeds back to the train control system. If the detection value of the pressure difference sensor 52 is too large, it means that the ventilation resistance of the air filter 50 is too large. At this time, the filter element of the air filter 50 may be dirty or blocked or other faults may occur. Therefore, the train control system sends an alarm to remind the staff to repair the air filter 50 in time; the dryer 70 preferably adopts a single-tower heatless regeneration dryer 70, the pressure dew point is stable and reliable, and it is convenient to disassemble and replace the drying tank of the dryer 70.

[0036] In order to improve the lightweight index of the wind source device, in this embodiment, the housing of the air compressor 20, the electric control box 40, the housing of the cooler 60, and the base frame 10 are preferably made of aluminum alloy.

[0037] Compared with the prior art, the virtual rail train wind source device provided by the present embodiment has an air compressor 20, a cooling fan 30, an electric control box 40, an air filter 50, a cooling zone device and a dryer 70 which are all integrated and installed on the base frame 10. Compared with the method of separately installing each component on the roof, there is no need to configure a separate installation structure for each component, and there is no need to arrange a connecting wire harness 16 or a pipe 17 between components on the roof, thereby reducing the difficulty of installation layout. In addition, the cooling fan 30 is arranged below the air compressor 20 to dissipate heat for the air compressor 20, the electric control box 40 is aligned with the air compressor 20, and the air filter 50, the cooler 60 and the dryer 70 are arranged on the side of the air compressor 20, thereby ensuring the compactness of the overall structure and avoiding the excessive size of the whole machine affecting the passability of the virtual rail train. In addition, since all components are integrated and installed on the base frame 10, maintenance personnel can complete the maintenance of the whole machine without moving, thereby reducing the difficulty of maintenance operations.

[0038] In some embodiments, see Figures 1 to 4 The base frame 10 includes an outer frame 11 and a middle beam 12 connected to the outer frame 11; wherein, two connecting seats 21 are respectively provided on both sides of the bottom of the air compressor 20, wherein the two connecting seats 21 on one side are connected to the middle beam 12, and the two connecting seats 21 on the other side are connected to the first side frame 111 of the outer frame 11 parallel to the middle beam 12.

[0039] The middle beam 12 divides the outer frame 11 into two installation areas, one of which is the combination of the middle beam 12 and the first frame 111 for installing the air compressor 20 and the electric control box 40, and the other area is arranged with the cooler 60, the dryer 70 and the air filter 50, which not only facilitates the integrated installation layout of various components, but also can use the middle beam 12 to improve the structural strength of the outer frame 11, thereby improving the stability of the overall structure.

[0040] Please note that Figure 1 and Figure 5 Two buffer support seats 121 are respectively provided on the middle beam 12 and the first frame 111, and each connection seat 21 is overlapped and fixed on each buffer support seat 121. Since there is a vibration problem during the operation of the air compressor 20, the air compressor 20 is connected to the base frame 10 through the buffer support seat 121, and the buffering characteristics of the buffer support seat 121 are used to reduce the vibration transmission from the air compressor 20 to the base frame 10, thereby avoiding frequent vibration of other components connected to the base frame 10 to affect the service life and working stability.

[0041] As a specific structural form of the buffer support seat 121, please refer to Figure 1 and Figure 5 The buffer support seat 121 includes a rigid base 1211 fixedly connected to the first frame 111 or the middle beam 12, and a rubber buffer column 1212 vulcanized and formed as one body with the rigid base 1211; wherein, a fastener 211 is pierced through the connection seat 21, and the fastener 211 passes through the rubber buffer column 1212 and is screwed and fixed to the rigid base 1211. The rigid base 1211 can be fixedly connected to the base frame 10 by welding or screwing, thereby improving the connection reliability. The rubber buffer column 1212 is vulcanized and fixed to the rigid base 1211 as one body, which can prevent the rubber buffer column 1212 from falling off. At the same time, the fastener 211 passes through the rubber buffer column 1212 and is connected to the rigid base 1211, which can further improve the connection stability and ensure the vibration reduction effect.

[0042] For some possible implementations, see Figure 1 and Figure 4 A heat dissipation base plate 13 is connected between the middle beam 12 and the first frame 111, a heat dissipation gap is provided between the heat dissipation base plate 13 and the air compressor 20, and two heat dissipation fans 30 are installed on the heat dissipation base plate 13 at intervals along the axial direction of the middle beam 12. Due to the existence of the buffer support seat 121, a gap sufficient to accommodate the heat dissipation fan 30 is formed between the air compressor 20 and the heat dissipation base plate 13, and the heat dissipation fan 30 is embedded after a hole is opened on the heat dissipation base plate 13, which can not only utilize the height (or thickness) space of the first frame 111 and the middle beam 12 for the layout of the heat dissipation fan 30, thereby improving the compactness of the structure, but also improving the installation stability of the heat dissipation fan 30.

[0043] In some embodiments, in combination Figure 1 and Figure 4 It is understood that the air compressor 20 includes a double-output motor 22 and two sets of compression units 23; the two sets of compression units 23 are respectively connected to the two ends of the double-output motor 22 and are respectively connected to the output shafts at the two ends of the double-output motor 22; and the two cooling fans 30 are respectively located directly below the two sets of compression units 23. Here, the double-output motor 22 refers to a motor with output shafts extending from both ends, so that the double-output motor 22 can simultaneously drive the compression units 23 at both ends to perform air compression. On this basis, each compression unit 23 is provided with a cooling fan 30 below for heat dissipation, thereby ensuring the heat dissipation efficiency and working stability of the air compressor 20.

[0044] It needs to be explained that the compression unit 23 includes a crankcase, a crankshaft, a piston rod, a piston and a compression cylinder. The dual-output motor 22 is connected to the crankshaft and drives the piston to move in the compression cylinder through the piston rod, thereby changing the volume of the compression cylinder and compressing the air. The specific structure of the compression unit 23 is prior art and will not be further described here.

[0045] See also Figure 4 In some embodiments, the second frame 112 of the outer frame 11 is opposite to the first frame 111, and a plurality of reinforcing beams 14 are connected between the second frame 112 and the middle beam 12, and the cooler 60, the dryer 70 and the air filter 50 are respectively installed on each reinforcing beam 14. The outer frame 11 can be a rectangular frame structure, the first frame 111 and the second frame 112 are respectively used as two opposite sides, and the middle beam 12 is located between the two. Therefore, the outer frame 11 is formed into two co-frame bodies based on the middle beam 12, one of which is used to install the air compressor 20 and the electric control box 40, and the second frame 112 and the middle beam 12 constitute the other frame. By setting the reinforcing beam 14 perpendicular to the middle beam 12, it serves as the installation base of the cooler 60, the dryer 70 and the air filter 50, which can not only improve the overall structural strength of the chassis 10, but also facilitate the cooler 60, the dryer 70 and the air filter 50 to be independently disassembled, repaired or replaced, and the connection reliability of the three can also be ensured.

[0046] It should be noted that see Figure 1 and Figure 3 The air inlet end of the air filter 50 faces upward and is covered with a rainproof cap 51. The air inlet end faces upward to facilitate the entry of outside air. At the same time, in order to prevent rainwater from entering the air filter 50 in rainy and snowy weather, a conical or hemispherical rainproof cap 51 is provided to shield the air inlet end of the air filter 50, thereby preventing rainwater from entering the air filter 50 and then entering the air compressor 20 to affect the normal operation of the air compressor 20.

[0047] In order to improve the stability of the wiring harness 16 and the pipeline 17, as Figures 1 to 4 As shown, a plurality of wire hoops 15 are arranged on the chassis 10, and the wire hoops 15 are used to fix the wire harness 16 and the pipeline 17. The wire harness 16 or the pipeline 17 can be prevented from being scattered or entangled with each other, and the connection reliability of the wire harness 16 and the pipeline 17 is improved.

[0048] Based on the same inventive concept, an embodiment of the present application also provides an urban virtual rail train, including the above-mentioned virtual rail train wind source device.

[0049] Compared with the prior art, the urban virtual rail train provided in this embodiment adopts the above-mentioned virtual rail train wind source device, and all components are integrated and installed on the chassis. The overall structure is compact and highly integrated, which is not only convenient for installation on the roof, but also does not require the laying of connecting wire harnesses and pipelines between components on the roof, and is also convenient for operators to carry out repairs and maintenance.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
