Description

[0002] With the rapid development of rail transit in recent years, rail transit has significantly improved the convenience of urban life. It reduces commuting time, alleviates urban traffic congestion, and promotes economic development by providing fast and punctual services.

[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 duct of the rail vehicle. Due to the humid environment in the air duct, the dust or impurities accumulated for a long time will become moldy and produce a musty smell. Therefore, the air duct needs to be cleaned to prevent the musty smell from entering the vehicle 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 to generate a strong airflow in the air duct to blow the dust and the like out of the air outlet of the air duct. However, using this method, due to the limited wind force provided by the airflow, it is still impossible to remove the stubborn stains that cause mildew adsorbed on the inner wall of the air duct. For example, the prior art (Announcement No. CN213316366U, a cleaning device built into the air duct, the air conditioning duct is a system and a vehicle) discloses a cleaning device, which can automatically clean the dust and the like in the air duct to improve the degree of automation.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] In the present invention, the directions or positional relationships indicated by "upper", "lower", "outer", etc. are based on the directions or positional relationships shown in the drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific direction, or to be constructed and operated in a specific direction.

[0038] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0039] In addition, the terms "installed", "set", "provided with", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0041] like Figure 1As shown, the specific structure of the air conditioning duct of a rail transit vehicle in the prior art is as follows: comprising a vehicle 1, an air conditioning duct 12 is arranged in the vehicle 1, and the specific air conditioning duct 12 can be arranged at the upper part or the bottom of the vehicle 1, a first air inlet 11 is arranged at one end of the air conditioning duct 12, and a second air inlet 13 is arranged at the other end of the air conditioning duct 12. In the prior art, high-pressure air is usually used to blow air toward the first air inlet 11 or the second air inlet 12 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, but this method is used. However, due to the limited wind force provided by the airflow, it is still impossible to remove the stubborn stains that are adsorbed on the inner wall of the air-conditioning duct 12 and cause mildew. For example, in the prior art, a cleaning device can be used to automatically clean the dust in the air-conditioning duct 12 to improve the degree of automation. However, after the cleaning device finishes cleaning, there is no other effective way to remove the dust remaining in the air-conditioning duct 12 after cleaning, so that some dust will still remain in the air-conditioning duct 12. It can be seen that the method provided by the prior art has the disadvantage that the air-conditioning duct 12 cannot be thoroughly cleaned.

[0042] Example 1

[0043] Based on the above-mentioned shortcomings of the prior art, Figure 1 The present embodiment shown provides a cleaning system for the air duct of the air conditioning of a rail transit vehicle, the cleaning system further comprising: a cleaning component 3, the cleaning component 3 is movably arranged in the air conditioning duct 12, wherein when the cleaning component 3 moves back and forth along the air conditioning duct 12, the cleaning component 3 performs a cleaning action on the air conditioning duct 12; a dust collection component 2, the dust collection component 2 includes two, one of the two dust collection components 2 is arranged on the first air inlet 11, and the other is arranged on the second air inlet 13, wherein when the dust collection component 2 located at the first air inlet 11 is moved back and forth, the dust collection component 2 is moved back and forth along the air conditioning duct 12, the cleaning component 3 performs a cleaning action on the air conditioning duct 12; and a dust collection component 2, the dust collection component 2 includes two, one of the two dust collection components 2 is arranged on the first air inlet 11, and the other is arranged on the second air inlet 13. When the dust collection component 2 blows or inhales air into the air conditioning duct 12, and the dust collection component 2 located at the second air inlet 13 inhales or blows air into the air conditioning duct 12 (specifically, when the dust collection component 2 located at the first air inlet 11 blows air into the air conditioning duct 12, the dust collection component 2 located at the second air inlet 13 inhales air into the air conditioning duct 12; when the dust collection component 2 located at the first air inlet 11 inhales air into the air conditioning duct 12, the dust collection component 2 located at the second air inlet 13 blows air into the air conditioning duct 12), the dust collection component 2 performs a dust collection action on the air conditioning duct 12. Specifically, inhaling air means that the dust collection component 2 generates suction force on the gas in the air conditioning duct 12 through the first air inlet 11 or the second air inlet 13, and inhales the gas in the air conditioning duct 12 into the dust collection component 2; blowing air means that the dust collection component 2 blows external gas into the air conditioning duct 12.

[0044] In this embodiment, a movable cleaning component 3 is provided in the air conditioning duct 12, and dust suction components 2 are respectively provided at the first air inlet 11 and the second air inlet 13 at both ends of the air conditioning duct 12. When one dust suction component 2 blows air into the air conditioning duct 12, the other dust suction component 2 sucks air into the air conditioning duct 12 (for example, when the dust suction component 2 located at the first air inlet 11 blows air into the air conditioning duct 12, the dust suction component 2 located at the second air inlet 13 sucks air into the air conditioning duct 12). First, the cleaning component 3 reciprocates in the air conditioning duct 12, and then the cleaning component 3 is moved back and forth in the air conditioning duct 12. The reciprocating movement of the cleaning component 3 increases the mechanical force on the inner wall of the air conditioning duct 12 during cleaning, so that the dust (especially stubborn stains) on the inner wall of the air conditioning duct 12 can be cleaned. Secondly, the alternating blowing and suction of multiple dust collecting components 2 can generate strong circulating airflows in different directions in the air conditioning duct 12 (for example, circulating airflow from the first air inlet 11 to the second air inlet 13 or circulating airflow from the second air inlet 13 to the first air inlet 11) to remove the dust and the like scattered on the air conditioning duct 12 after cleaning. Therefore, this embodiment achieves the technical effect of thoroughly cleaning the air conditioning duct 12 through the mutual cooperation of the cleaning component 3 and the dust collecting component 2.

Specifically, the driving part 32 can be a self-propelled cart 321, and the self-propelled cart 321 can be an AGV cart. The AGV cart can realize autonomous cruising of the cleaning part 31 in the air-conditioning duct 12, thereby improving the degree of automation of the entire device.

[0046] In this embodiment, a cleaning component 3 is provided which consists of a cleaning part 31 and a driving part 32. The driving part 32 is connected to the cleaning part 31. The driving part 32 drives the cleaning part 31 to move back and forth in the air-conditioning duct 12, thereby realizing the reciprocating movement of the cleaning part 31 in the air-conditioning duct 12. The reciprocating movement of the cleaning part 31 increases the mechanical force on the inner wall surface of the air-conditioning duct 12 during cleaning, and dust and the like (especially stubborn stains) on the inner wall surface of the air-conditioning duct 12 can be cleaned.

[0047] In order to fully clean the inner wall surface of the air conditioning duct, preferably, the cleaning unit 31 includes: an installation frame 311, the installation frame 311 includes a first frame 3111, a second frame 3112, a third frame 3113 and a fourth frame 3114 connected in sequence, and the first frame 3111, the second frame 3112, the third frame 3113 and the fourth frame 3114 are respectively arranged in one-to-one correspondence with the four inner wall surfaces of the air conditioning duct 12, specifically, as shown in FIG. Figure 4 As shown in FIG. 1 , when the cross section of the air conditioning duct 12 (eg Figure 1 The direction of the cross-section shown is the cross-section along the AA direction) when the shape is a rectangle, the inner wall surfaces of the air-conditioning duct 12 are the upper inner wall surface, the lower inner wall surface, the left inner wall surface and the right inner wall surface, the first frame 3111 is arranged corresponding to the upper inner wall surface, the second frame 3112 is arranged corresponding to the left inner wall surface, the third frame 3113 is arranged corresponding to the lower inner wall surface, and the fourth frame 3114 is arranged corresponding to the right inner wall surface; the first group of brush heads 312, the first group of brush heads 312 includes two groups, and the two groups of first group brush heads 312 are rotatably arranged on the surfaces of the first frame 3111 and the third frame 3113 respectively; the second group of brush heads 313, the second group of brush heads 313 includes two groups, and the two groups of second group brush heads 313 are rotatably arranged on the surfaces of the second frame 3112 and the fourth frame 3114 respectively.

Since the four frames of the installation frame 311 are respectively arranged in a one-to-one correspondence with the four inner wall surfaces of the air conditioning duct 12, the first group of brush heads 312 that are respectively rotatably arranged on the four frames to perform a cleaning action can be made. The brush head 312 and the second group of brush heads 313 clean the four inner wall surfaces of the air-conditioning duct 12 at the same time (for example, when the first frame 3111 is arranged to correspond to the upper inner wall surface of the air-conditioning duct 12, the second frame 3112 is arranged to correspond to the left inner wall surface of the air-conditioning duct 12, the third frame 3113 is arranged to correspond to the lower inner wall surface of the air-conditioning duct 12, and the fourth frame 3114 is arranged to correspond to the right inner wall surface of the air-conditioning duct 12, the first group of brush heads 312 located on the first frame 3111 and the third frame 3113 can clean the upper and lower inner wall surfaces of the air-conditioning duct 12, and the second group of brush heads 313 located on the second frame 3112 and the fourth frame 3114 can clean the left and right inner wall surfaces of the air-conditioning duct 12), thereby achieving the technical effect of comprehensively cleaning the inner wall surfaces of the air-conditioning duct 12.

[0049] In order to further improve the cleaning of the inner wall of the air conditioning duct by the brush head, preferably, the shape and size of the mounting frame 311 match the shape and size of the cross section of the air conditioning duct 12; specifically, Figure 4 As shown in FIG. 1 , when the cross section of the air conditioning duct 12 (eg Figure 1 When the cross section (the direction of the cross section shown is the cross section along the AA direction) is rectangular, the shape of the mounting frame 311 is also rectangular, and at this time, the inner wall surface of the air conditioning duct 12 is the upper inner wall surface, the lower inner wall surface, the left inner wall surface and the right inner wall surface, the width of the first frame 3111 matches the width of the upper inner wall surface, the width of the second frame 3112 matches the width of the left inner wall surface, the width of the third frame 3113 matches the width of the lower inner wall surface, and the width of the fourth frame 3114 matches the width of the right inner wall surface.
