Description

Technical Field

[0001] The present application relates to the technical field of cleaning air ducts of rail transit vehicles' air conditioning systems, and in particular to a dust collection device and a cleaning system for rail transit vehicles' air ducts. Background Art

[0002] With the rapid development of rail transit in recent years, rail transit has significantly improved the convenience of urban life. By providing fast and punctual services, it has reduced commuting time, alleviated urban traffic congestion, and promoted economic development.

[0003] However, during the operation of subways and other rail vehicles, due to the poor air quality in operating environments such as tunnels, after the air-conditioning system filters the fresh air and return air, a large amount of dust and impurities still accumulate in the air ducts of the rail vehicles. Due to the humid environment in the air ducts, the dust or impurities accumulated for a long time will become moldy and produce a musty odor. Therefore, the air ducts need to be cleaned to prevent the musty odor from entering the car and affecting the passengers' riding environment.

[0004] In the prior art, high-pressure air is usually blown toward the air inlet of the air duct, generating a strong airflow in the air duct to blow the dust and the like out of the air outlet of the air duct. However, in this way, since the negative pressure vacuum cleaner used in the prior art has a blocking plate, when vacuuming the air-conditioning duct of a rail transit vehicle, the blocking plate is first installed at the air inlet, and then suction is generated in the air-conditioning duct through the air duct provided on the blocking plate, thereby vacuuming the dust in the air-conditioning duct. After the vacuuming is completed using the above structure, since the motor stops rotating, no airflow will be generated in the air duct (i.e., the suction disappears), so that the dust remaining adsorbed on the inner wall of the air duct and the surface of the blocking plate will fall back into the air-conditioning duct under the action of gravity, resulting in incomplete vacuuming of the air-conditioning duct. Utility Model Content

[0005] In view of this, the purpose of the present application is to provide a dust collection device and a cleaning system for the air conditioning duct of a rail vehicle, so as to achieve the technical effect of thoroughly collecting dust from the air conditioning duct.

[0006] A first aspect of an embodiment of the present application discloses a dust suction device for an air duct of an air-conditioning vehicle of a rail transit vehicle, the dust suction device comprising: a first air duct; a dust suction chamber connected to the first air duct; and an isolation door rotatably disposed on the dust suction chamber.

[0007] In one embodiment, the length of the dust suction chamber matches the length of the air inlet of the air-conditioning duct; the width of the dust suction chamber matches the width of the air inlet of the air-conditioning duct; and the height of the dust suction chamber matches the height of the air-conditioning duct.

[0008] In one embodiment, a first drive motor is provided on the dust suction chamber; a first rotating shaft is provided on the isolation door, and the isolation door is rotatably connected to the dust suction chamber through the first rotating shaft; a transmission part is provided between the first drive shaft of the first drive motor and the first rotating shaft.

[0009] In one embodiment, the transmission part includes a driving gear, which is arranged on the first driving shaft; and a transmission gear, which is arranged on the first rotating shaft; wherein the driving gear and the transmission gear are meshed.

[0010] In one embodiment, the transmission part includes a first pulley, which is arranged on the first driving shaft; a second pulley, which is arranged on the first rotating shaft; and a first flexible belt, which is arranged between the first pulley and the second pulley and enables the first pulley and the second pulley to cooperate in transmission.

[0011] In one embodiment, the isolation door is provided with a first magnet on a side thereof facing away from the dust collection chamber; and the inner wall surface of the air conditioning duct is provided with a second magnet cooperating with the first magnet.

[0012] In one embodiment, a first interface and a second interface are respectively provided at both ends of the first air duct.

[0013] In one embodiment, the first air duct is a corrugated hose.

[0014] In one embodiment, the dust collection device further includes the dust collecting bag, and the dust collecting bag is connected to the first air duct.

[0015] The present application sets a dust suction chamber connected to the first air duct, and an isolation door is rotatably provided on the dust suction chamber. When the dust suction action starts, the dust suction chamber is first placed into the air-conditioning duct from the air inlet of the air-conditioning duct, and then the isolation door is opened. The flow of gas in the first air duct generates suction in the air-conditioning duct. Under the action of suction, the dust in the air-conditioning duct passes through the dust suction chamber in turn and is discharged from the air-conditioning duct after the first air duct. When the dust suction is completed, the isolation door is closed to form a closed space in the dust suction chamber connected to the first air duct. The residual dust adsorbed on the inner wall of the first air duct will only fall into the dust suction chamber under the action of gravity. Since the dust suction chamber is isolated from the air-conditioning duct by the closed space formed by the isolation door, the residual dust will not enter the air-conditioning duct again, thereby achieving the technical effect of thoroughly vacuuming the air-conditioning duct.

[0016] A second aspect of an embodiment of the present application discloses a cleaning system for an air-conditioning duct of a rail transit vehicle, wherein an air inlet is provided at one end of the air-conditioning duct, and the system also includes the dust collection device, which is provided on the air inlet.

[0017] The present application provides a cleaning system with a dust suction device, which first provides a dust suction chamber connected to the first air duct, and an isolation door is rotatably provided on the dust suction chamber. When the dust suction action starts, the dust suction chamber is first placed into the air-conditioning duct from the air inlet, and then the isolation door is opened. The flow of gas in the first air duct generates suction in the air-conditioning duct. Under the action of suction, the dust in the air-conditioning duct passes through the dust suction chamber in turn and is discharged from the air-conditioning duct after the first air duct. When the dust suction is completed, the isolation door is closed to form a closed space in the dust suction chamber connected to the first air duct. The dust remaining adsorbed on the inner wall of the first air duct will only fall into the dust suction chamber under the action of gravity. Since the closed space formed by the isolation door in the dust suction chamber is isolated from the air-conditioning duct, the remaining dust will not enter the air-conditioning duct again, thereby achieving the technical effect of thoroughly vacuuming the air-conditioning duct.

[0026] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] In this utility model, the directions or positions indicated by terms such as "upper," "lower," and "outer" are based on the directions or positions shown in the accompanying drawings. These terms are primarily intended to better describe the utility model and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific direction, or to being constructed or operated in a specific direction.

[0028] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0029] Furthermore, the terms "installed," "disposed," "equipped with," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0030] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0031] like Figure 4As shown, the specific structure of the rail transit vehicle in the prior art is as follows: it includes a carriage 1, an air conditioning duct 12 is provided in the carriage 1, and the specific air conditioning duct 12 can be provided at the upper part or the bottom of the carriage 1, and an air inlet 11 is provided at one end of the air conditioning duct 12. In the prior art, high-pressure air is usually blown toward the air inlet 11 of the air conditioning duct 12, and a strong airflow is generated in the air conditioning duct 12 to blow dust and the like out of the air outlet of the air conditioning duct 12. However, in this way, since the negative pressure vacuum cleaner used in the prior art has a blocking disk, When vacuuming the air conditioning duct 12 of a rail transit vehicle, the blocking plate is first installed on the air inlet 11, and then suction is generated in the air conditioning duct 12 through the air duct provided on the blocking plate, thereby vacuuming the dust in the air conditioning duct 12. After the vacuuming is completed using the above structure, since the motor stops rotating, no airflow will be generated in the air duct (i.e., the suction disappears), so that the dust remaining adsorbed on the inner wall of the air duct and the surface of the blocking plate will fall back into the air conditioning duct 12 under the action of gravity, resulting in incomplete vacuuming of the air conditioning duct 12.

[0032] Example 1

[0033] Based on the above-mentioned shortcomings of the prior art, Figure 1-4 As shown, this embodiment provides a dust collection device for the air duct of the rail transit vehicle air conditioning, and the dust collection device 2 includes a first air duct 24; a dust collection chamber 29, which is connected to the first air duct 24; and an isolation door 21, which is rotatably arranged on the dust collection chamber 29.

[0034] In this embodiment, a dust collection chamber 29 connected to the first air duct 24 is provided, and an isolation door 21 is rotatably provided on the dust collection chamber 29. When the dust collection action starts (that is, the dust collection chamber 29 is placed into the air conditioning duct 12 through the air inlet 11 of the air conditioning duct 12), the isolation door 21 is first opened, and the flow of gas in the first air duct 24 generates suction in the air conditioning duct 12. Under the action of the suction, the dust in the air conditioning duct 12 passes through the dust collection chamber 29 in turn and is discharged from the air conditioning duct 12 after the first air duct 24. When the dust collection is completed, the isolation door 21 is closed, so that a closed space is formed in the dust collection chamber 29 connected to the first air duct 24. The dust remaining adsorbed on the inner wall of the first air duct 24 will only fall into the dust collection chamber 29 under the action of gravity. Since the closed space formed by the isolation door 21 of the dust collection chamber 29 is isolated from the air conditioning duct 12, the remaining dust will not enter the air conditioning duct 12 again, thereby achieving thorough dust collection in the air conditioning duct 12.

[0035] In order to prevent dust from being discharged from the gap, preferably, the length of the dust suction chamber 29 matches the length of the air inlet 11; the width of the dust suction chamber 29 matches the width of the air inlet 11; the height of the dust suction chamber 29 matches the height of the air conditioning duct 12, specifically, as Figure 3-4As shown, when the air inlet 11 is rectangular and when the air-conditioning duct 12 is a cuboid, the shape of the dust suction chamber 29 is a cuboid, the length of the dust suction chamber 29 matches the length of the air inlet 11, the width of the dust suction chamber 29 matches the width of the air inlet 11; the height of the dust suction chamber 29 matches the height of the air-conditioning duct 12.

[0036] In this embodiment, the length of the dust suction chamber 29 is set to match the length of the air inlet 11, the width of the dust suction chamber 29 is set to match the width of the air inlet 11, and the height of the dust suction chamber 29 is set to match the height of the air conditioning duct 12. Figure 3 As shown, when the dust collection chamber 29 enters the air-conditioning duct 12 through the air inlet 11, a gap can be avoided between the dust collection chamber 29 and the air inlet 11 along the width or length direction of the air inlet 11 and the height direction of the air-conditioning duct 12, thereby effectively preventing dust from being discharged from the gap to the outside of the air-conditioning duct 12.

[0037] In order to realize the rotation of the isolation door relative to the dust collection chamber, preferably, a first drive motor 26 is provided on the dust collection chamber 29; a first rotating shaft 22 is provided on the isolation door 21, and the isolation door 21 is rotatably connected to the dust collection chamber 29 through the first rotating shaft 22; a transmission part 28 is provided between the first drive shaft 27 of the first drive motor 26 and the first rotating shaft 22.

[0038] In this embodiment, a first drive motor 26 is provided on the dust collection chamber 29, and a first rotating shaft 22 is provided on the isolation door 21. The isolation door 21 is rotatably connected to the dust collection chamber 29 through the first rotating shaft 22. One end of the first rotating shaft 22 is coupled with the first drive shaft 27 of the first drive motor 26 through a transmission part 28. The first drive shaft 27 is driven to rotate by the first drive motor 26, and the first drive shaft 27 transmits power to the first rotating shaft 22 through the transmission part 28, so that the first rotating shaft 22 drives the isolation door 21 to rotate relative to the dust collection chamber 29 with the first rotating shaft 22 as the origin.

[0039] In order to improve the stability of the first driving motor driving the isolation door to rotate, the transmission part 28 includes a driving gear, which is arranged on the first driving shaft 27; and a transmission gear, which is arranged on the first rotating shaft 22; wherein the driving gear and the transmission gear are meshed.

[0040] In this embodiment, a transmission portion 28 consisting of a driving gear and a transmission gear is used. The driving gear is mounted on the first driving shaft 27, and the transmission gear is mounted on the first rotating shaft 22. The driving gear and the transmission gear are meshed with each other. Since the driving gear and the transmission gear have stable transmission matching performance, the stability of the first drive motor 26 driving the isolation door 21 to rotate is improved.

[0041] In order to improve the stability of the first drive motor driving the isolation door to rotate, the transmission part 28 includes a first pulley, which is arranged on the first drive shaft 27; a second pulley, which is arranged on the first rotating shaft 22; and a first flexible belt, which is arranged between the first pulley and the second pulley, and makes the first pulley and the second pulley cooperate in transmission.

[0042] In this embodiment, a transmission part 28 consisting of a first pulley, a second pulley and a first flexible belt is used. The first pulley is installed on the first drive shaft 27, and the second pulley is installed on the first rotating shaft 22. The first pulley and the second pulley are matched through the first flexible belt transmission. Since the pulley and the flexible belt have stable transmission matching performance, the stability of the first drive motor 26 driving the isolation door 21 to rotate is improved.

[0043] In order to prevent dust from remaining between the isolation door and the air conditioning duct, preferably, the isolation door 21 is provided with a first magnet on the side thereof facing away from the dust collection chamber 29; and the inner wall surface of the air conditioning duct 12 is provided with a second magnet cooperating with the first magnet.

[0044] In this example, a first magnet is arranged on the side of the isolation door 21 facing away from the dust collection bin 29, and a second magnet is arranged on the inner wall surface of the air-conditioning duct 12 to cooperate with the first magnet. Through the interaction between the first magnet and the second magnet, when the isolation door 21 is opened, the isolation door 21 can be firmly adsorbed on the inner wall surface of the air-conditioning duct 12 to avoid the formation of a gap between the isolation door 21 and the inner wall surface of the air-conditioning duct 12, thereby preventing dust from remaining between the isolation door 21 and the air-conditioning duct 12 during the vacuuming operation.

[0045] To facilitate connection of the first air duct with other components, preferably, a first interface 23 and a second interface 25 are respectively provided at both ends of the first air duct 24. Specifically, the first air duct 24 is connected to the dust collection chamber 29 through the first interface 23, and the first air duct 24 is connected to the dust collection bag 210 through the second interface 25.

[0046] In this embodiment, a first interface 23 and a second interface 25 are respectively provided at both ends of the first air duct 24, thereby facilitating the connection of the first air duct 24 with other components.

[0047] In order to facilitate the stretching and bending of the first air duct, preferably, the first air duct 24 is a corrugated hose.

[0048] In this embodiment, the first air duct 24 is made of a corrugated hose, so that the first air duct 24 has good flexibility, which facilitates the bending and stretching of the first air duct 24.

[0049] In order to facilitate the collection of dust and other impurities in the air-conditioning duct, the dust collection device 2 further includes a dust collecting bag 210 , which is connected to the first air duct 24 .

[0050] In this embodiment, the dust collecting device 2 includes a dust collecting bag 210 , which can facilitate the collection of dust and other impurities sucked out from the air conditioning duct 12 .

[0051] Example 2

[0052] This embodiment provides a cleaning system for the air conditioning duct of a rail transit vehicle having the dust collection device of Embodiment 1. An air inlet 11 is provided at one end of the air conditioning duct 12 , and the dust collection device 2 is provided on the air inlet 11 .

[0053] In this embodiment, a cleaning system with a dust collection device 2 is provided. The dust collection device 2 first sets a dust collection chamber 29 connected to the first air duct 24. An isolation door 21 is rotatably provided on the dust collection chamber 29. When the dust collection action is started, the dust collection chamber 29 is first placed into the air conditioning duct 12 from the air inlet 11, and then the isolation door 21 is opened. The flow of gas in the first air duct 24 generates suction in the air conditioning duct 12. The dust in the air conditioning duct 12 passes through the dust collection chamber 29 in sequence under the action of the suction force. The dust in the first air duct 24 is then sucked out of the dust collection chamber 29. Afterwards, it is discharged from the air conditioning duct 12. When the dust collection is completed, the isolation door 21 is closed, thereby forming a closed space in the dust collection chamber 29 connected to the first air duct 24. Dust remaining adsorbed on the inner wall of the first air duct 24 will fall into the dust collection chamber 29 due to gravity. Because the dust collection chamber 29 is isolated from the air conditioning duct 12 by the closed space formed by the isolation door 21, the remaining dust will not re-enter the air conditioning duct 12, thereby achieving the technical effect of thoroughly cleaning the air conditioning duct 12.

Each embodiment focuses on the differences from other embodiments. The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the rights of the present application.
