Description

Technical Field

[0001] The invention relates to the technical field of train electric heaters, and in particular to a train passenger compartment electric heater capable of achieving rapid heating and heat dissipation. Background Art

[0002] The train passenger compartment electric heater is a device installed in the train passenger compartment to provide passengers with a comfortable riding environment in cold weather. This heater usually uses electricity as energy, generates heat through electric heating elements, and evenly distributes the heat in the compartment through the air circulation system. The design of the electric heater needs to take into account factors such as vibration, temperature changes and space limitations during train operation to ensure that it can work stably in various environments. In addition, the maintenance of the electric heater is relatively simple, which helps to reduce operating costs. At the same time, there are many people in the train, and the electric heater also needs to ventilate and dissipate heat during use.

[0003] After searching, it is found that there are problems with the train electric heater in the prior art. Since the train electric heater heats the outside air to achieve the temperature increase of the train passenger compartment, and the air intake of the train electric heater is limited by the size of the air inlet, resulting in limited air intake, so that the amount of heated air is limited, the heating speed is slow, and the humidity in the air is constantly changing. It is difficult for the train electric heater to adjust the air humidity. When the air humidity is low, the heated air is extremely dry, which makes the interior of the train passenger compartment dry and may cause breathing discomfort to passengers. When the air humidity is high, the air is humid. After heating, the humid air may cause the train passenger compartment to be hot and humid, which will also affect the comfort of passengers. At the same time, although the train electric heater can increase the temperature in the train, the train itself has many passengers. The breathing of the passengers may further increase the temperature in the train and cause the air in the train to be stuffy, further reducing the passenger's riding experience and affecting the staff's use of the train electric heater. Therefore, based on the above search and combined with the prior art, a train passenger compartment electric heater that can achieve rapid heating and heat dissipation is proposed to solve the above problems.

[0032] The fast heating and heat dissipation mechanism 7 includes a support hole 5, which is opened on the top surface of the processing box 1. The support hole 5 is slidably connected to a liftable air intake box 6. The air intake box 6 is lifted and lowered to change the air intake volume. The bottom surface of the air intake box 6 is rotatably connected to a plurality of air intake fans 49 for air intake. A HEPA filter 9 is slidably connected to one side of the processing box 1. Both sides of the HEPA filter 9 are connected to the processing box 1 by bolts, which can not only fix the HEPA filter 9 but also facilitate subsequent disassembly and maintenance. The HEPA filter 9 is used to filter the air. A hygrometer 44 for detecting air humidity is installed on one side of the air intake box 6, and air intake grilles for preventing debris from entering the air intake box 6 are installed on both sides of the air intake box 6. A separation plate 13 for dividing the heating cavity is fixedly installed inside the processing box 1, and a support plate 17 for air diversion is arranged on the top surface of the separation plate 13. An activated carbon filter 20 for filtering air is installed inside the processing box 1 by bolts. A mounting plate 25 is arranged inside the processing box 1, and a plurality of exhaust fans 26 for exhausting air are rotatably connected to the top surface of the mounting plate 25.

[0033] The rapid heating and heat dissipation mechanism 7 includes two support blocks 18, both of which are fixedly mounted on the top surface of the separation plate 13, and connecting rollers 19 are fixedly mounted on both sides of the support plate 17, and the connecting rollers 19 are rotatably connected to the support blocks 18, and one end of the connecting roller 19 passes through the processing box 1 and is rotatably connected to the processing box 1 through a bearing, and one end of the connecting roller 19 located on the left side is fixedly mounted with a mounting frame 57, and a rack 2 58 is fixedly mounted on the inner top surface and the inner bottom surface of the mounting frame 57, and a sliding frame 61 is slidably connected to the outside of the mounting frame 57, and a gear 2 59 is rotatably connected to the inside of the sliding frame 61, and a rotating roller 60 is fixedly mounted on both ends of the gear 2 59, and the rotating roller 60 is rotatably connected to the sliding frame 61, and the gear 2 59 is meshedly connected to the rack 2 58, and two connecting blocks 64 are fixedly mounted on the top surface of the sliding frame 61, and a connecting rod 65 is rotatably connected between the two connecting blocks 64 through a rotating shaft;

[0034] Two bearing seats 3 54 are fixedly installed on one side of the processing box 1. The two bearing seats 3 54 are internally rotatably connected with a lead screw 2 51. The outer circumferential wall of the lead screw 2 51 is threadedly connected to a sliding block 53. A DC motor 50 for driving the lead screw 2 51 to rotate is installed on one side of the processing box 1 through a bracket. One end of the driving shaft of the DC motor 50 is fixedly connected to one end of the lead screw 2 51. A limit rod 55 is fixedly installed between the two bearing seats 3 54. The sliding block 53 is slidably connected to the limit rod 55. The limit rod 55 can limit the movement of the sliding block 53 to prevent the sliding block 53 from rotating. A mounting seat 56 is fixedly installed on one side of the sliding block 53. One end of the connecting rod 65 is rotatably connected to the mounting seat 56 through a pin. The staff sets a suitable humidity threshold range for the hygrometer 44. When the air humidity is within the threshold range, the support plate 17 keeps the vertical air passing through the channels on both sides of the separation plate 13 and heats it into the train passenger compartment.

[0035] When the air humidity is lower than the threshold, the DC motor 50 drives the lead screw 51 to rotate, and the lead screw 51 rotates to make the sliding block 53 move downward, and the sliding block 53 moves downward to drive the connecting rod 65 to rotate downward, and the connecting rod 65 rotates downward to drive the sliding frame 61 to slide outward on the mounting frame 57, and at the same time makes the gear 59 rotate outward between the two racks 58, and the sliding frame 61 moves outward and also makes the mounting frame 57 rotate clockwise, and the mounting frame 57 rotates clockwise through the connecting roller 19 to drive the support plate 17 to rotate clockwise until it abuts against one side of the partition 10, and at this time, the air will enter the left channel of the separation plate 13;

[0036] Vice versa, when the air humidity exceeds the threshold, the support plate 17 rotates counterclockwise until it abuts against one side of the interior of the processing box 1, and the air enters the right channel of the separation plate 13;

[0037] Heater bodies 15 for heating air are installed on both the left and right sides of the separation plate 13. Two humidifiers 14 are fixedly installed on the left side of the separation plate 13, and a dehumidifier 16 is fixedly installed on the right side of the separation plate 13. In the left channel of the separation plate 13, the heater body 15 is located above the two humidifiers 14, so that the air is mixed with the water vapor of the humidifiers 14 after being heated and enters the train, while in the right channel of the separation plate 13, the dehumidifier 16 is located above the heater body 15, and the humid air is dehumidified by the dehumidifier 16 and then heated and finally enters the train passenger compartment, so as to avoid moisture in the train passenger compartment;

[0038] Two support rods 21 are fixedly installed between one side of the partition 10 and one side of the interior of the processing box 1, and a support frame 22 is slidably connected to the outside of the support rod 21. Two fixed blocks 23 are fixedly installed on the top surface of the support frame 22, and two support seats 24 are fixedly installed on the bottom surface of the mounting plate 25. The support seat 24 is rotatably connected to the two fixed blocks 23 through pins. Two mounting blocks 28 are fixedly installed on one side of the mounting plate 25, and a movable block 29 is rotatably connected between the two mounting blocks 28 through a rotating shaft. Two bearing seats 27 are fixedly installed on one side of the processing box 1, and a screw rod 30 is rotatably connected between the two bearing seats 27. The screw rod 30 is threadedly connected to the movable block 29. A driving motor 31 for driving the screw rod 30 to rotate is fixedly installed on one side of the processing box 1, and one end of the driving shaft of the driving motor 31 is fixedly connected to the top of the screw rod 30;

[0039] When the train is leaving or entering the station, the speed is relatively slow, and the staff starts the multiple exhaust fans 26. The multiple exhaust fans 26 rotate so that the hot air inside the train passenger compartment is filtered through the activated carbon filter 20 and the barrier net 11 and then discharged;

[0040] When the train speeds up, the high speed makes the air pressure on the top of the train lower than the air pressure inside the train compartment. The negative pressure makes the hot air in the train compartment be discharged through the barrier net 11. At this time, the driving shaft of the driving motor 31 rotates to drive the screw rod 30 to rotate. The screw rod 30 rotates to make the movable block 29 move upward. The movable block 29 moves upward to drive the mounting plate 25 to tilt upward. At the same time, the mounting plate 25 drives the support frame 22 to slide on the support rod 21 until the mounting plate 25 and the exhaust fan 26 are tilted on one side of the inside of the treatment box 1 to prevent the mounting plate 25 and the exhaust fan 26 from affecting the discharge of hot air in the train compartment. The intermittent use of the exhaust fan 26 also reduces the energy consumption when the train compartment dissipates heat. A PLC controller is fixedly installed on one side of the treatment box 1. The air intake fan 49, the hygrometer 44, the DC motor 50, the humidifier 14 and the dehumidifier 16 are all electrically connected to the PLC controller.

[0041] Through the above technical features, by setting the processing box 1, the staff installs the processing box 1 on the top of the train passenger compartment, and the internal partition 10 of the processing box 1 can divide the processing box 1 into two cavities for heating and heat dissipation;

[0042] In order to increase the temperature of the train passenger compartment, during the running of the train, the outside air will enter the interior of the treatment box 1 through the air intake box 6, and the air intake fan 49 inside the air intake box 6 can transport the air, and the air intake box 6 can be raised and lowered. When the air intake box 6 moves upward, the area of ​​the air intake box 6 exceeding the top surface of the treatment box 1 increases, so that the air intake volume increases. The increase in the air intake volume increases the amount of heated air, so that the train passenger compartment is quickly heated;

[0043] Secondly, the air entering through the air inlet box 6 will first be filtered by the HEPA filter 9, which can filter bacteria and dust in the air to ensure clean air and improve the air quality inside the train passenger compartment;

[0044] Among them, the HEPA filter 9 is a HEPA high efficiency filter, which can remove particles with a diameter of more than 1 / 200 of the diameter of a 0.3 micron hair at a removal efficiency of more than 99.7%, and is the most effective filtering medium for pollutants such as smoke, dust and bacteria;

[0045] At the same time, during the air intake process, the hygrometer 44 inside the air intake box 6 can detect the air humidity, and the staff sets a suitable threshold value for the air humidity, and the specific value is determined according to the actual situation;

[0046] When the air humidity is within this range, the support plate 17 is in a vertical state, and the air will enter the train passenger compartment after being heated by the heater body 15 in the channels on the left and right sides of the separation plate 13; when the air humidity is lower than the threshold range, the air is relatively dry, and the drive shaft of the DC motor 50 rotates to drive the lead screw 2 51 to rotate, and the rotation of the lead screw 2 51 causes the sliding block 53 to move downward along the limit rod 55 and the lead screw 2 51, and the sliding block 53 moves downward to drive the mounting seat 56 to move downward, and the mounting seat 56 moves downward to drive the connecting rod 65 to rotate downward, and the connecting rod 65 rotates downward to cause the sliding frame 61 to move outward along the mounting frame 57, and the sliding frame 61 moves outward along the mounting frame 57 so that the gear 2 59 is between the two racks 2 58 The rolling between the gears 59 and the sliding frame 61 causes the rotating roller 60 to rotate. The sliding frame 61 moves outward to cause the mounting frame 57 to rotate clockwise. The mounting frame 57 rotates clockwise through the connecting roller 19 to drive the supporting plate 17 to rotate clockwise between the two supporting plates 17 until it abuts against one side of the partition 10. At this time, the channel on the left side of the separation plate 13 is blocked by the supporting plate 17, and the air will enter the left channel of the guide frame 3. The heater body 15 in the left channel of the guide frame 3 first heats the filtered air. At the same time, the two humidifiers 14 will generate water vapor, which is mixed with the heated air and enters the train passenger compartment through the connecting plate 2, thereby allowing the train passenger compartment to heat up quickly when the external air humidity is low.

[0047] When the air humidity is greater than the threshold range, the sliding block 53 will drive the mounting seat 56 to move upward along the lead screw 2 51. The mounting seat 56 moves upward and drives the sliding frame 61 to slide on the mounting frame 57 through the connecting rod 65. At the same time, the gear 2 59 inside the sliding frame 61 rolls along the two racks 2 58. At this time, the mounting frame 57 drives the connecting roller 19 and the supporting plate 17 to rotate counterclockwise until one side of the supporting plate 17 abuts against the inner side of the processing box 1. The supporting plate 17 blocks the channel on the left side of the separation plate 13, and the air will enter the channel on the right side of the separation plate 13. The dehumidifier 16 on the right side of the separation plate 13 can dehumidify the humid air and reduce its humidity. Then the heater body 15 will heat the air, and the heated air will enter the train passenger compartment through the connecting plate 2, thereby allowing the train passenger compartment to heat up quickly when the external air humidity is high.

[0048] Regarding the heat dissipation of the train passenger compartment, when the train leaves or enters the station, the speed is relatively slow, and the staff will start multiple exhaust fans 26. The exhaust fans 26 rotate to allow the hot air in the train passenger compartment to enter the heat dissipation cavity inside the treatment box 1 through the connecting plate 2. The activated carbon filter 20 in the heat dissipation cavity can filter the hot air to remove the odor and then discharge it through the barrier net 11.

[0049] During the running of the train, the speed is relatively fast, so that the air pressure on the roof is lower than the air pressure inside the train passenger compartment. The negative pressure on the roof makes the hot air in the train passenger compartment quickly discharged after being filtered by the activated carbon filter 20. At this time, the staff starts the driving motor 31, and the driving shaft of the driving motor 31 rotates to drive the screw rod 30 to rotate. The rotation of the screw rod 30 makes the movable block 29 move upward. The movable block 29 moves upward through the mounting block 28 to drive one side of the mounting plate 25 to move upward. The one side of the mounting plate 25 moves upward to make the support seat 24 rotate around the fixed block 23 and drive the support frame 22 to move backward along the support rod 21 until the mounting plate 25 tilts to the inner side of the processing box 1, preventing the mounting plate 25 and the exhaust fan 26 from blocking the exhaust of the hot air in the train passenger compartment, thereby quickly cooling the train passenger compartment. Intermittent use of multiple exhaust fans 26 can also reduce energy consumption.

[0050] During this process, the staff increases the air intake of the treatment box 1 by lifting and lowering the air intake box 6. The increase in the air intake increases the amount of hot air, which helps the train passenger compartment to quickly heat up. When the air is taken in, the air can also be dehumidified and humidified according to the different air humidity, ensuring that the humidity of the train passenger compartment is maintained at an appropriate level during the heating process; at the same time, when the train enters and leaves the station, multiple exhaust fans 26 will be used for heat dissipation and ventilation. When the train is running, negative pressure will be used to suck out the hot air in the train passenger compartment, which can not only quickly dissipate the heat of the train passenger compartment but also reduce energy consumption, thereby achieving the effect of rapid heating and heat dissipation of the train passenger compartment, making it convenient for the staff to install the treatment box 1 on the train for use;

[0051] A rack 39 is fixedly installed on the bottom surface of the air intake box 6, and a gear 41 is meshedly connected to the outer circumferential wall surface of the rack 39, and a support roller 40 is fixedly sleeved on the inner circumferential wall surface of the gear 41. A bearing seat 42 is fixedly installed on one side of the interior of the processing box 1, and one end of the gear 41 is rotatably connected to one end of the bearing seat 42. The bearing seat 42 can support the rotation of the support roller 40 and the gear 41. A driving motor 3 43 is installed on one side of the interior of the processing box 1 through a bracket, and one end of the driving shaft of the driving motor 3 43 is fixedly connected to one end of the support roller 40. The driving shaft of the driving motor 3 43 rotates through the support roller 40 to drive the gear 41 to rotate. The rotation of the gear 41 causes the rack 39 to drive the air intake box 6 to move upward. The upward movement of the air intake box 6 makes the area of ​​the air intake box 6 higher than the top surface of the processing box 1 larger, thereby increasing the air intake amount of the processing box 1. The increase in the air intake amount increases the amount of heated air, which helps to quickly increase the temperature of the train passenger compartment.

[0052] A limiting groove 37 is provided on one side of the processing box 1, and a limiting block 38 is slidably connected inside the limiting groove 37. One side of the limiting block 38 is fixedly connected to one side of a rack 1 39, and a driving motor 3 43 is electrically connected to a PLC controller;

[0053] Specifically, by setting a driving motor 3 43, the driving shaft of the driving motor 3 43 rotates to drive the support roller 40 to rotate, and the rotation of the support roller 40 drives the gear 1 41 to rotate, and the rotation of the gear 1 41 causes the rack 1 39 to move upward and the limiting block 38 to move upward inside the limiting groove 37 inside the processing box 1. The limiting groove 37 and the limiting block 38 cooperate to limit the movement of the rack 1 39, and the upward movement of the rack 1 39 drives the air intake box 6 to move upward. The upward movement of the air intake box 6 increases the area where the air intake box 6 is higher than the top surface of the processing box 1, thereby increasing the air intake amount of the processing box 1, which is helpful for the subsequent rapid heating of the train passenger compartment;

[0054] A slide groove 52 is provided on one side of the processing box 1, and both sides of the slide groove 52 are inclined inwardly. A slider 12 is fixedly installed on one side of the air intake box 6, and the slider 12 is slidably connected with the slide groove 52. The movement of the air intake box 6 drives the slider 12 to move inside the slide groove 52. The slider 12 and the slide groove 52 cooperate to limit the movement of the air intake box 6.

[0055] Specifically, by setting up the air intake box 6, the air intake box 6 moves upward to drive the slider 12 to move upward inside the inner slide groove 52 of the processing box 1. The slider 12 and the slide groove 52 can limit the movement of the air intake box 6, thereby achieving a limiting effect on the air intake box 6.

[0056] As a preferred implementation in this embodiment, please refer to Figures 1 to 9The closing member includes two bidirectional screw rods 32, both of which are rotatably connected to the inside of the treatment box 1, one end of the bidirectional screw rod 32 is rotatably connected to one side of the inside of the treatment box 1 through a bearing, and the outer circumferential wall surfaces of the two bidirectional screw rods 32 are threadedly connected to two cover plates 8 for closing the barrier net 11, one end of the bidirectional screw rod 32 passes through one side of the treatment box 1 and extends outside the treatment box 1, and a synchronous wheel 34 is fixedly installed on one end of the bidirectional screw rod 32, and a synchronous belt 35 is rotatably connected between the two synchronous wheels 34;

[0057] A driving motor 2 33 for driving a synchronous wheel 34 to rotate is installed on one side of the processing box 1. The driving shaft of the driving motor 2 33 rotates to drive the two synchronous wheels 34 to rotate through the synchronous belt 35. The rotation of the two synchronous wheels 34 causes the bidirectional screw rod 32 to rotate. The rotation of the bidirectional screw rod 32 causes the two cover plates 8 to move inward until the two cover plates 8 merge. The two cover plates 8 can block the barrier net 11, thereby controlling the heat dissipation time of the train passenger compartment. One end of the driving shaft of the driving motor 2 33 is fixedly connected to one end of the synchronous wheel 34 on the left side, and the driving motor 2 33 is electrically connected to the PLC controller.

[0058] Specifically, through the drive motor 2 33, the drive shaft of the drive motor 2 33 rotates to drive the synchronous wheel 34 to rotate, the synchronous wheel 34 rotates to drive another synchronous wheel 34 to rotate through the synchronous belt 35, the two synchronous wheels 34 rotate to drive the two bidirectional screw rods 32 to rotate, the two bidirectional screw rods 32 rotate to make the two cover plates 8 move inward along the bidirectional screw rods 32 until they are merged together, at this time the two cover plates 8 can block the blocking net 11, so as to control the ventilation and heat dissipation of the train passenger compartment;

[0059] The staff can move the two cover plates 8 to block part of the blocking net 11, thereby controlling the efficiency of ventilation and heat dissipation according to demand;

[0060] The top and bottom surfaces of the mounting frame 57 are fixedly mounted with limit bars 62 for limiting the position of the sliding frame 61. The limit bars 62 can limit the sliding of the sliding frame 61 to prevent it from detaching. The inner top and bottom surfaces of the sliding frame 61 are provided with positioning grooves 63, and the positioning grooves 63 are slidably connected to the limit bars 62.

[0061] Specifically, by setting the sliding frame 61, the sliding frame 61 slides on the installation frame 57 and slides along the limit bar 62. The limit bar 62 and the positioning groove 63 cooperate to limit the sliding of the sliding frame 61 to prevent it from detaching from the installation frame 57.

[0062] A baffle 4 is fixedly installed on the bottom surface of the processing box 1, and the baffle 4 can isolate the intake and ventilation. A guide frame 3 is fixedly installed on the bottom surface of the processing box 1, and a plurality of guide plates 46 are fixedly installed on the inner bottom surface of the guide frame 3. The plurality of guide plates 46 cooperate with the guide frame 3 to form an air duct for guiding hot air. A positioning plate 47 is fixedly installed on the inner bottom surface of the guide frame 3, and a plurality of fans 48 for conveying hot air are rotatably connected to one side of the positioning plate 47, and the fans 48 are electrically connected to the PLC controller;

[0063] Specifically, through the processing box 1, the heated air inside the processing box 1 will fall into the inside of the guide frame 3, and the staff will start the fan 48, which will rotate to transport the heated air and then cooperate with the air duct formed by the guide frame 3 and multiple guide plates 46 to quickly transport the heated air to various places in the train passenger compartment, thereby improving the rapid heating effect of the train passenger compartment;

[0064] A protection box 45 for protecting the DC motor 50 is installed on one side of the processing box 1 by bolts, and a protection box 36 for protecting the driving motor 33 is installed on the other side of the processing box 1 by bolts;

[0065] Specifically, by setting up the protection box 2 45 , the protection box 2 45 can protect the DC motor 50 , and the protection box 1 36 can protect the drive motor 2 33 , thereby preventing the drive motor 2 33 and the DC motor 50 from being damaged.

[0066] Working principle: through the treatment box 1, the staff installs the treatment box 1 on the top of the train, and the external air enters the inside of the treatment box 1 through the air intake box 6. The staff changes the air intake volume by raising and lowering the air intake box 6. The driving shaft of the driving motor 3 43 rotates through the supporting roller 40 to drive the gear 1 41 to rotate. The rotation of the gear 1 41 makes the rack 1 39 move upward. The upward movement of the rack 1 39 drives the air intake box 6 to move upward. The upward movement of the air intake box 6 increases the area of ​​the air intake box 6 above the top surface of the treatment box 1, and then cooperates with the air intake fan 49 inside the air intake box 6 to increase the air intake volume to prepare for rapid heating.

[0067] Secondly, after the air enters the air intake box 6, the hygrometer 44 in the air intake box 6 can detect its humidity. When the air humidity is within the threshold range set by the staff, the support plate 17 is in a vertical state, and the air entering the processing box 1 passes through the heater body 15 in the channels on both sides of the separation plate 13 to enter the train passenger compartment for heating, thereby quickly heating up the train passenger compartment;

[0068] When the air humidity is less than the threshold range, the air is relatively dry, and the DC motor 50 drives the lead screw 2 51 to rotate. The lead screw 2 51 rotates to make the sliding block 53 move downward, and the sliding block 53 moves downward to drive the connecting rod 65 to rotate downward. The connecting rod 65 rotates downward to drive the sliding frame 61 to slide outward on the mounting frame 57 and make the gear 2 59 roll outward between the two racks 2 58. The sliding frame 61 moves outward and also makes the mounting frame 57 rotate clockwise. The mounting frame 57 rotates clockwise through the connecting roller 19 to drive the support plate 17 to rotate clockwise until it abuts against one side of the partition 10. At this time, the air will enter the left channel of the separation plate 13, and the heater body 15 in the left channel will heat the air, and the humidifier 14 therein will produce water vapor. The heated air mixed with water vapor enters the train passenger compartment, so that the train passenger compartment can be quickly heated up when the external air humidity is low while avoiding excessive dryness in the train passenger compartment.

[0069] Vice versa, when the air humidity exceeds the threshold, the support plate 17 will rotate counterclockwise until it abuts against one side of the interior of the processing box 1. At this time, the air enters the right channel of the separation plate 13. The dehumidifier 16 in the right channel will dehumidify the humid air. The dehumidified air enters the interior of the processing box 1 after being heated by the heater body 15, thereby allowing the train passenger compartment to quickly heat up when the external air humidity is high while preventing the air in the train passenger compartment from being too humid.

[0070] Next, the processed hot air will enter the interior of the guide frame 3, and the fan 48 inside the positioning plate 47 cooperates with the air duct formed by the guide plate 46 and the guide frame 3 to transport the hot air to various places in the train passenger compartment, thereby improving the rapid heating effect of the train passenger compartment;

[0071] Finally, when the train passenger compartment needs to be cooled, since the train leaves and enters the station at a slow speed, the staff starts multiple exhaust fans 26, and the multiple exhaust fans 26 rotate so that the hot air inside the train passenger compartment is filtered through the activated carbon filter 20 and the barrier net 11 and then discharged;

[0072] When the train speeds up, the air pressure on its top is lower than the air pressure inside the train compartment, and the negative pressure causes the hot air in the train compartment to be discharged through the barrier net 11. At the same time, the driving motor 31 drives the screw rod 30 to rotate, and the rotation of the screw rod 30 causes the movable block 29 to move upward. The upward movement of the movable block 29 drives the mounting plate 25 to tilt upward, and at the same time, the mounting plate 25 drives the support frame 22 to slide on the support rod 21 until the mounting plate 25 and the exhaust fan 26 are tilted on the inner side of the processing box 1, so as to prevent the mounting plate 25 and the exhaust fan 26 from blocking the rapid discharge of hot air in the train compartment, and the intermittent use of the exhaust fan 26 will also reduce the energy consumption when the train compartment dissipates heat.

[0073] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
