[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0043] Example 1

[0044] See also Figure 1 —4 and Figure 7 A mobile channel four-brush bus washing machine includes a ground embedded part 100, a mobile washing mechanism 200 and a fixed washing mechanism 300, wherein the ground embedded part 100 is buried inside the ground, and includes a guide rail 101 and a limit assembly 102 located at one end of the guide rail 101;

[0045] Furthermore, the mobile scrubbing mechanism 200 includes a mobile base 201, a mobile frame 202, a mobile scrubbing assembly A203, and a mobile scrubbing assembly B204. The mobile base 201 is fixedly connected with the mobile frame 202. The mobile scrubbing assembly A203 is provided on one end side of the mobile frame 202, and the mobile scrubbing assembly B204 is provided on the other end side. In addition, the corresponding mobile scrubbing assemblies A203 and B204 on the mobile frame 202 are fixedly connected with spray assemblies A205. In addition, the above-mentioned mobile base 201 can cooperate with the guide rail 101, so that the mobile base 201 slides along the guide rail 101, that is, the mobile scrubbing mechanism 200 moves along the guide rail 101, and the above-mentioned mobile base 201 matches the limiting assembly 102, so that when the mobile base 201 moves to the corresponding limiting assembly 102, the mobile scrubbing mechanism 200 can be limited by the limiting assembly 102.

[0046] Furthermore, the fixed scrubbing mechanism 300 corresponds to the mobile scrubbing assembly, and the fixed scrubbing mechanism 300 includes a fixed frame 301, a fixed scrubbing assembly A302, and a fixed scrubbing assembly B303. The fixed frame 301 is provided with a fixed scrubbing assembly A302 at one end, and a fixed scrubbing assembly B303 at the other end. The fixed scrubbing assembly A302 and the fixed scrubbing assembly B303 on the fixed frame 301 are both fixedly connected with a spray assembly B304. Furthermore, the fixed frame 301 is also rotatably connected with a swing rod 600, and the other end of the swing rod 600 is rotatably connected to the mobile frame 202.

[0047] Furthermore, the movable base 201 is also provided with a lifting guide assembly 400, which includes a screw 401, a rotating handle 402 and a roller 403. The movable base 201 is threadedly connected with the screw 401, and the bottom end of the screw 401 is rotatably connected with the roller 403. The roller 403 is located in the guide track 101, and the top end of the screw 401 is fixedly connected with the rotating handle 402. In this way, by rotating the rotating handle 402, the screw 401 can be rotated, thereby causing the roller 403 to rise or fall. When the roller 403 rises, , the tight contact between the roller 403 and the bottom surface of the guide track 101 can be released, so that the roller 403 can move on the guide track 101, and when the roller 403 descends, the bottom surface of the roller 403 can be tightly contacted with the bottom surface of the guide track 101, thereby realizing the limit of the mobile base 201, and then fixing the mobile washing mechanism 200, and when the roller 403 rises and completely leaves the bottom surface of the guide track 101, the mobile base 201 can be contacted with the limit assembly 102, thereby realizing the limit assembly 102 on the mobile base 201;

[0048] In summary, the handle 402 can be rotated to make the roller 403 rise, at which time the roller 403 conflicts with the bottom surface of the guide track 101, and then the mobile washing mechanism 200 is pushed to move in the guide track 101 until the mobile base 201 corresponds to the limit assembly 102. In addition, the rotating handle 402 is rotated again to make the roller 403 away from the bottom surface of the guide track 101. In addition, the mobile base 201 descends and conflicts with the limit assembly 102, and the mobile base 201 is limited by the limit assembly 102. In addition, the mobile washing mechanism 200 is fixed and is currently in a working state;

[0049] When the bus passes through the mobile washing mechanism 200 and the fixed washing mechanism 300, the bus can be cleaned;

[0050] When the working state is released, the rotating handle 402 can be rotated to make the mobile base 201 rise. Furthermore, the limiting component 102 releases the limit on the mobile washing mechanism 200, and then the mobile washing mechanism 200 is pushed so that the mobile washing mechanism 200 and the fixed washing mechanism 300 are in the same space. Finally, the rotating handle 402 is rotated again to make the roller 403 tightly contact the bottom surface of the guide track 101. In this way, the car washing machine can be folded, so that the vacated space can be used for parking or as a passage, so as to reasonably utilize the car washing site.

The piston end of the driving cylinder B214 is rotatably connected to the driving arm B216. The driving cylinder B214 can pull the driving arm B216 and the rotating arm B217 to rotate, so that the roller brush A206 contacts the side of the bus.

[0055] Further, there are:

[0056] The fixed brush assembly A302 includes a roller brush C305, a motor C306, and a driving cylinder C307. A shaft rod C308 is rotatably connected to one end of the fixed frame 301. A driving arm C309 and a rotating arm C310 are fixedly connected to the shaft rod C308. A roller brush C305 is rotatably connected between the driving arm C309 and the rotating arm C310. A motor C306 is fixedly connected to the driving arm C309 or the rotating arm C310. The motor C306 is dynamically connected to the roller brush C305. A driving cylinder C307 is also rotatably connected to the fixed frame 301. The piston end of the driving cylinder C307 is rotatably connected to the driving arm C309. The driving cylinder C307 can pull the driving arm C309 and the rotating arm C310 to rotate, so that the roller brush C305 can collide with the front face, side face, and rear face of the bus.

[0057] The fixed brush assembly B303 includes a roller brush D311, a motor D312, and a driving cylinder D313. One end side of the fixed frame 301 is rotatably connected to a shaft rod D314, and a driving arm D315 and a rotating arm D316 are fixedly connected to the shaft rod D314.

The driving cylinder D313 can pull the driving arm D315 and the rotating arm D316 to rotate, so that the roller brush D311 can collide with the side of the bus.

[0058] And then there are the following:

[0059] The spray assembly A205 and the spray assembly B304 both include a mounting frame 501, a delivery pipe 502 and a spray head 503.

[0060] The multiple groups of delivery pipes 502 are connected by delivery pipelines 504, and a pump 505 is provided on the delivery pipeline 504;

[0061] In summary, when the car washer is in working condition, the bus can enter between the mobile washing brush assembly A203 and the fixed washing brush assembly A302. At this time, the pump 505 pressurizes the water in the water tank and sprays it on the surface of the bus through the spray assembly A205 and the spray assembly B304. Then, the roller brushes A206 and C305 are driven to move through the driving cylinders A208 and C307, so that the roller brushes A206 and C305 collide with the front end surface of the bus to clean the front end surface of the bus. Then, the bus continues to travel, and the driving cylinders A208, B214 and C314 are used to clean the front end surface of the bus. C307 and driving cylinder D313 drive roller brushes A206, roller brush B212, roller brush C305 and roller brush D311 to move, so that the four groups of roller brushes are in contact with the side of the bus to clean the side of the bus. When the bus reaches the end, driving cylinder A208 and driving cylinder C307 drive roller brushes A206 and roller brush C305 to move, so that roller brushes A206 and roller brush C305 are in contact with the rear end surface of the bus to clean the rear end surface of the bus. Such structural design can improve the cleaning effect of the bus, and can wash cars one after another continuously to speed up the car washing efficiency.
