Description

Technical Field

[0001] This application relates to the field of train cleaning technology, and in particular to a dust prevention and self-cleaning device for car wash machine cleaning brushes. Background Technology

[0002] When a train is in operation, pollutants such as dust, carbon powder, iron filings, and shellac in the air can easily adhere to the train's surface and accumulate over a long period of time, forming yellow spots and stubborn grime. Therefore, it is necessary to clean the train's surface regularly to ensure its cleanliness.

[0003] A car wash machine's cleaning brush assembly is a washing device used for cleaning the exterior of train vehicles. It brushes the sides of the train's exterior to keep it clean. During the washing process, the brush bristles inevitably become contaminated, retaining some dirt. The degree of dirt on the bristles gradually increases with use. If not cleaned promptly, it can cause secondary pollution to the train surface during the wash, affecting the washing effect. Furthermore, most car wash machines are located outdoors, and even when not in use, they are affected by weather factors such as sandstorms and rain, leading to a decrease in cleanliness. Due to their large size, manually cleaning the brush bristles is difficult and inefficient, and the cleanliness of the bristles cannot meet the requirements of car washes. Utility Model Content

[0004] Therefore, it is necessary to provide a dustproof and self-cleaning device for the cleaning brush assembly of a car wash machine, which can provide dustproof protection and cleaning for the cleaning brush assembly when the car wash machine is not in operation.

[0005] This application provides a dustproof and self-cleaning device for a car wash machine's cleaning brush assembly, comprising:

[0006] The protective chamber is constructed with a space for accommodating the cleaning brush assembly of the car wash machine; one side of the protective chamber is provided with an inlet and outlet, through which the bristle components of the cleaning brush assembly of the car wash machine can enter and exit the protective chamber.

[0007] A protective door mechanism includes a protective door, which is rotatably connected to the protective compartment to block or avoid the entrance / exit;

[0008] A cleaning mechanism is installed inside the protective chamber; the cleaning mechanism is capable of spraying water to clean the bristle assembly.

[0009] In one embodiment, the cleaning mechanism includes:

[0010] A water spray pipe is installed on the inner wall of the protective chamber, with the spray nozzle of the water spray pipe facing the brush assembly that has moved into the protective chamber.

[0011] In one embodiment, the cleaning mechanism further includes:

[0012] A scraper is disposed on the inner wall of the protective chamber. When the bristle assembly moves into the protective chamber, at least a portion of the scraper is inserted into the bristles of the bristle assembly.

[0013] In one embodiment, the protective door is linked to the car wash machine's cleaning brush assembly;

[0014] When the brush assembly moves into the protective chamber, the car wash machine cleaning brush group drives the protective door to rotate and block the inlet and outlet;

[0015] When the brush assembly moves to the outside of the protective chamber, the car wash machine's cleaning brush group drives the protective door to rotate and avoid the inlet and outlet.

[0016] In one embodiment, the car wash cleaning brush assembly further includes a brush bow and a cleaning brush assembly base; the brush bow connects the cleaning brush assembly base and the bristle assembly, and the cleaning brush assembly base can drive the brush bow to rotate so as to move the bristle assembly in and out of the protective chamber.

[0017] The protective door mechanism also includes:

[0018] A linkage assembly, one end of which is rotatably connected to the protective door, and the other end of which is fixedly connected to the brush bow. The brush bow drives the protective door to rotate through the linkage assembly.

[0019] In one embodiment, the protective door is provided in two sets, and the two sets of protective doors are respectively rotatably connected to the two side walls of the protective cabin adjacent to the entrance and exit; the two protective doors rotate toward the entrance and exit to jointly block the entrance and exit.

[0020] In one embodiment, each of the protective doors is provided with one of the linkage groups, and the connection points of the two linkage groups with the brush bow are symmetrically arranged with respect to the rotation axis of the brush bow.

[0021] In one embodiment, the end of the protective door away from the connection point with the protective cabin is bent inward into the protective cabin.

[0022] In one embodiment, the protective door is connected to the end of the sidewall away from the inlet / outlet, and the protective door extends along the sidewall and bends toward the inlet / outlet to block the inlet / outlet.

[0023] In one embodiment, the protective cabin includes:

[0026] Multiple columns are spaced apart on the mounting base and enclose a space for accommodating the car wash machine cleaning brush assembly. The back plate is connected to the columns, and the inlet and outlet are formed between two of the columns.

[0027] A top plate is disposed at the top of the column, and the top plate forms the top of the accommodating space.

[0028] The aforementioned dustproof and self-cleaning device for the car wash machine's cleaning brush assembly provides dust protection by enclosing the brush assembly in a protective chamber. An inlet / outlet is located on one side of the protective chamber, allowing the brush bristles to enter and exit. When not washing, the bristles remain inside the chamber; when washing is required, they move outside to clean the surrounding trains. A rotating protective door, connected to the chamber, blocks the inlet / outlet, further enhancing the protection of the brush assembly and providing clearance for the bristles. Furthermore, a cleaning mechanism within the protective chamber sprays water to clean the brush assemblies, solving the problems of difficult and inefficient manual cleaning.

[0047] Please see Figure 1 and Figure 2 , Figure 1 This is a front view of a car wash cleaning brush assembly 100 provided in one embodiment of the present application. Figure 2 This diagram shows a top view of a car wash cleaning brush assembly 100 provided in one embodiment of this application. The car wash cleaning brush assembly 100 includes a bristle assembly 110, a brush bow 120, and a cleaning brush assembly base 130. The brush bow 120 connects the cleaning brush assembly base 130 and the bristle assembly 110, and the cleaning brush assembly base 130 can drive the brush bow 120 to rotate, thereby moving the bristle assembly 110 closer to or further away from the train to be cleaned. The cleaning brush assembly base 130 can drive the brush bow 120 to rotate via a motor or a rotary cylinder, etc.

[0048] The brush assembly 110 includes a brush shaft 111 and brush bristles 112. The brush shaft 111 is rotatably connected to the brush bow 120. The brush bristles 112 are disposed on the surface of the brush shaft 111. The rotation of the brush shaft 111 drives the brush bristles 112 to rotate synchronously, so that the brush bristles 112 contact the train surface to achieve brushing. Specifically, the car wash machine cleaning brush assembly 100 also includes a brush drive 140. The fixed end of the brush drive 140 is disposed on the brush bow 120, and the driving end of the brush drive 140 is connected to the brush shaft 111 to drive the brush shaft 111 to rotate. The brush drive 140 can specifically adopt a structure such as a motor or a rotary cylinder, as long as it can drive the brush shaft 111 to rotate. The specific structural form is not limited here.

[0049] It should be noted that the embodiments of this application mainly provide a dustproof and self-cleaning device for the car wash machine cleaning brush group 100 mentioned above, and do not involve any improvement to the structure of the car wash machine cleaning brush group 100 itself. Therefore, the specific structure and working principle of the car wash machine cleaning brush group 100 will not be described in detail here.

[0050] Please refer to the following: Figure 3 and Figure 4 , Figure 3 This illustration shows a schematic diagram of the dustproof and self-cleaning device for a car wash brush assembly provided in one embodiment of the present application in a protected state. Figure 4 This illustration shows a schematic diagram of the dustproof and self-cleaning device for a car wash brush assembly provided in one embodiment of this application in a non-protected state.

[0051] To prevent dust and enable self-cleaning of the aforementioned car wash brush assembly 100, this application provides a dust prevention and self-cleaning device for the car wash brush assembly, including a protective chamber 1, a protective door mechanism 2, and a cleaning mechanism. The protective chamber 1 has a accommodating space for accommodating the car wash brush assembly 100; one side of the protective chamber 1 is provided with an inlet / outlet 10, through which the bristle assembly 110 of the car wash brush assembly 100 can enter and exit the protective chamber 1. The protective door mechanism 2 includes a protective door 21, which is rotatably connected to the protective chamber 1 to block or avoid the inlet / outlet 10. The cleaning mechanism is disposed inside the protective chamber 1 and can spray water to clean the bristle assembly 110.

[0052] The dustproof and self-cleaning device for car wash brush assembly provided in this embodiment of the application provides dust protection for the car wash brush assembly 100 by setting up a protective chamber 1 to house it. An inlet / outlet 10 is provided on one side of the protective chamber 1, allowing the brush bristle assembly 110 of the car wash brush assembly 100 to enter and exit the protective chamber 1 through the inlet / outlet 10. When car washing is not required, the brush bristle assembly 110 remains inside the protective chamber 1; when car washing is required, it moves to the outside of the protective chamber 1 through the inlet / outlet 10 to clean the vehicles outside the protective chamber 1. A protective door 21, rotatably connected to the protective chamber 1, blocks the inlet / outlet 10, improving the protection of the car wash brush assembly 100. The protective door 21 also avoids the inlet / outlet 10, providing a buffer for the entry and exit of the brush bristle assembly 110. Furthermore, a cleaning mechanism is installed inside the protective chamber 1 to spray water and clean the brush bristle assembly 110, solving the problems of difficulty and low efficiency associated with manual cleaning.

[0053] Please see Figures 5-7 , Figure 5 A front view structural schematic diagram of the protective chamber 1 provided in one embodiment of this application is shown; Figure 6 A top view of the protective cabin 1 provided in one embodiment of this application is shown; Figure 7 A side view of the protective cabin 1 provided in one embodiment of this application is shown.

[0054] The protective enclosure 1 includes a mounting base 11, a back plate 12, multiple columns 13, and a top plate 14. The back plate 12 is mounted on the mounting base 11. The multiple columns 13 are spaced apart on the mounting base 11, forming a space to accommodate the car wash brush assembly 100. The back plate 12 is connected to the columns 13, with an inlet / outlet 10 formed between two columns 13. The top plate 14 is located at the top of the columns 13, forming the top of the space. By setting the mounting base 11 to support the installation of the back plate 12 and the multiple columns 13, and by placing the top plate 14 at the top of the columns 13, the top plate 14, the columns 13, and the back plate 12 enclose the space to accommodate the car wash brush assembly 100.

[0055] In this embodiment, four columns 13 are provided, arranged in a square. An inlet / outlet 10 is formed between the two front columns 13. The two rear columns 13 provide support for the installation of the back plate 12. A top plate 14 is connected to the tops of the two rear columns 13 and extends forward to cover the car wash brush assembly 100. There are gaps between the two left-side columns 13 and the two right-side columns 13, which can be sealed by a protective door 21, as will be described in detail later.

[0056] Optionally, the protective chamber 1 also includes multiple connecting columns 15, which are arranged around the accommodating space of the protective chamber 1. The connecting columns 15 connect two adjacent columns 13 and serve as reinforcing ribs to prevent the columns 13 from tilting.

[0057] Optionally, the connecting column 15 is not provided between the two columns 13 forming the inlet and outlet 10, so as to prevent the connecting column 15 from interfering with the brush assembly 110 and affecting the brush assembly 110's entry and exit from the protective chamber 1.

[0058] Specifically, the cleaning brush assembly base 130 is housed within the protective chamber 1, the bristle shaft 111 extends vertically, and the brush bow 120 drives the bristle assembly 110 to rotate horizontally through the inlet and outlet 10. Figure 3 Taking the perspective shown as an example, the bristle assembly 110 is located inside the protective chamber 1. The bristle assembly 110 rotates counterclockwise around the cleaning brush assembly base 130, gradually approaching the inlet / outlet 10 and moving from the inlet / outlet 10 to the outside of the protective chamber 1. When it is necessary to return to the inside of the protective chamber 1, it can be rotated in the opposite direction.

[0059] In some embodiments, please refer to Figure 3 and Figure 4 The cleaning mechanism includes a water spray pipe 31, which is installed on the inner wall of the protective chamber 1, specifically on the two front columns 13. The water spray nozzles 311 of the water spray pipe 31 are oriented towards the brush assembly 110 that has moved into the protective chamber 1. When the brush assembly 110 finishes its brushing operation and returns to the protective chamber 1, the water spray nozzles 311 spray water to clean the brush assembly 110.

[0060] Specifically, the end of the water spray pipe 31 away from the water nozzle 311 is connected to a water supply device, which supplies water to the water spray pipe 31. A water pump can be installed on the water spray pipe 31 to provide pressure to the water in the water spray pipe 31, thereby increasing the pressure of the water sprayed from the water nozzle 311 and improving the rinsing effect on the bristles 112.

[0061] Please refer to Figure 5 Corresponding to the vertical extension of the bristle shaft 111, the water spray pipe 31 extends vertically along the inner wall of the protective chamber 1. The water spray pipe 31 is provided with multiple vertically spaced water spray nozzles 311 so that the water spray range of the water spray pipe 31 can cover the entire bristle 112, thereby improving the water spray cleaning effect.

[0062] In some embodiments, please refer back to the documentation. Figure 3The cleaning mechanism also includes a scraper 32, which is disposed on the inner wall of the protective chamber 1, specifically on the rear connecting column 15 or the back plate 12. When the bristle assembly 110 moves into the protective chamber 1, at least a portion of the scraper 32 is inserted into the bristles 112 of the bristle assembly 110. When the bristle shaft 111 rotates, the bristles 112 continuously impact the scraper 32 to scrape away the dirt remaining on the bristles 112.

[0063] Optionally, the scraper 32 extends in the vertical direction and its length is not less than the vertical extension length of the bristles 112, so that the scraper 32 can act on the entire bristles 112.

[0064] Specifically, before the bristles 112 come into contact with the scraper 32, water is sprayed onto the bristles 112 through the water spray pipe 31, which is more conducive to improving the scraping and cleaning effect of the scraper 32 on the bristles 112.

[0065] In some embodiments, please refer to Figure 3 and Figure 4 The protective door 21 is linked to the car wash machine cleaning brush assembly 100. When the brush assembly 110 moves into the protective chamber 1, the car wash machine cleaning brush assembly 100 drives the protective door 21 to rotate and block the inlet / outlet 10. When the brush assembly 110 moves outside the protective chamber 1, the car wash machine cleaning brush assembly 100 drives the protective door 21 to rotate and avoid the inlet / outlet 10. The protective door 21 can be automatically opened and closed by the car wash machine cleaning brush assembly 100 without manual adjustment or additional adjustment devices.

[0066] Specifically, in order to achieve linkage between the protective door 21 and the car wash machine cleaning brush assembly 100, the protective door mechanism 2 also includes a linkage assembly 22. One end of the linkage assembly 22 is rotatably connected to the protective door 21, and the other end is fixedly connected to the brush bow 120. The brush bow 120 drives the protective door 21 to rotate through the linkage assembly 22.

[0067] In this embodiment, the linkage assembly 22 includes a linkage 221, a first linkage seat 222, and a second linkage seat 223. The two ends of the linkage 221 are rotatably connected to the first linkage seat 222 and the second linkage seat 223, respectively. The end of the first linkage seat 222 away from the linkage 221 is fixedly connected to the protective door 21, and the end of the second linkage seat 223 away from the linkage 221 is fixedly connected to the brush bow 120. When the brush bow 120 rotates, it drives the second linkage seat 223, which is fixedly connected to it, to rotate synchronously. The linkage 221 then rotates, causing the first linkage seat 222, which is fixedly connected to the protective door 21, to move. The first linkage seat 222 then pushes the protective door 21 to rotate relative to the rotational connection shaft between the protective door 21 and the protective compartment 1, thereby opening or closing the protective door 21.

[0068] Understandably, the linkage 22 can also use other linkage combinations that can drive the protective door 21 to rotate and open or close the inlet / outlet 10.

[0069] Optionally, two sets of protective doors 21 are provided, each set rotatably connected to one of the two side walls of the protective compartment 1 adjacent to the entrance / exit 10. The two protective doors 21 rotate toward the entrance / exit 10, jointly blocking the entrance / exit 10. With this configuration, when the protective doors 21 are opened, the two protective doors 21 rotate to the left and right respectively to avoid the entrance / exit 10, occupying less space and helping to avoid interference with the train to be cleaned.

[0070] Optionally, each protective door 21 is provided with a linkage group 22. The connection points of the two linkage groups 22 with the brush bow 120 are symmetrically arranged with respect to the rotation axis of the brush bow 120, so that the brush bow 120 provides opposite rotational driving forces to the protective door 21, driving the left protective door 21 to rotate clockwise and driving the right protective door 21 to rotate counterclockwise.

[0071] In some embodiments, the protective door 21 is connected to the end of the side wall away from the inlet / outlet 10. The protective door 21 extends along the side wall and bends toward the inlet / outlet 10 to block the inlet / outlet 10. That is, the protective door 21 is generally L-shaped and is arranged around the outer side of the protective compartment 1.

[0072] Specifically, two protective doors 21 are connected to the left and right rear pillars 13 of the protective compartment 1, respectively. The left protective door 21 can seal the gap between the two left pillars 13, and the right protective door 21 can seal the gap between the two right pillars 13, thereby improving the airtightness of the protective compartment 1. When the protective doors 21 are opened, they rotate to the left and right sides of the protective compartment 1, respectively, which makes it easier to avoid trains.

[0073] Optionally, the end of the protective door 21 furthest from its connection point with the protective compartment 1 is bent inwards towards the interior of the protective compartment 1. (Refer to...) Figure 5 This design allows the free end of the protective door 21 to bend away from the train when the door is opened, further preventing interference between the protective door 21 and the train.

[0074] In some embodiments, such as Figure 4 As shown, a magnet 23 is provided at the free end of the protective door 21. When the two protective doors 21 are closed, the magnets 23 of the two protective doors 21 attract each other to improve the reliability of the two protective doors 21 in blocking the inlet and outlet 10.

[0075] To improve the structural strength and ease of installation of the protective door 21, the protective door mechanism 2 also includes a bracket 24, which is located on the inner side of the protective door 21 to provide support for it. The linkage assembly 22 can be connected to the bracket 24, and by driving the bracket 24 to move, the protective door 21 can be rotated through the bracket 24.

[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
