Technical Field

[0001] The present invention relates to the field of highway maintenance equipment, and in particular to a cleaning mechanism and a cleaning method for highway mid-strips, and a vehicle with the cleaning mechanism. Background Art

[0002] The median strip of a highway is used to separate two-way lanes. Generally, a double solid yellow line is drawn on the median strip and a fence is set up on the double solid yellow line. Figure 9 As shown, the fence 200 includes fence stakes 210 arranged at intervals and guardrails 220 connected to the fence stakes. Due to the existence of the fence 200, the median strip 300 occupied by it is difficult to clean, especially the median strip below the guardrail 220 between the two fence stakes 210; in the prior art, although a vehicle-mounted cleaning machine is equipped, it is limited in flexibility and often only cleans both sides of the fence. Over time, a large amount of dust and garbage will accumulate in the median strip 300 at the lower end of the fence, seriously affecting the cleanliness of traffic. Summary of the Invention

[0098] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of specific embodiments of the present invention. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0100] According to a first aspect of the present invention, a cleaning mechanism 100 is Figures 1 to 3 、 Figure 9 As shown, including:

[0101] base 110;

[0102] The extension arm assembly 120 is connected to the base 110 at one end and is configured to adjust the position of the extension arm assembly 120 in the height direction G; since the working conditions of the road section to be cleaned are relatively complex, for example, there is a height difference between the height of the road section to be cleaned and the vehicle that drives the cleaning mechanism 100 to move; the height of the cleaning assembly 130 can be flexibly adjusted through the extension arm assembly 120 to improve its flexibility and adaptability.

[0103] The cleaning assembly 130 is connected to the other end of the extension arm assembly 120 through an adjusting member 135, and includes a chassis 131, a brush 132 movably connected to the chassis 131, and a first driving member 133 that drives the brush 132 to perform periodic motion, wherein the adjusting member 135 is configured to adjust the cleaning assembly 130 to rotate 180 degrees from the initial position or deflect and restore to the initial position after the cleaning assembly 130 encounters an obstacle.

[0104] The working principle of the cleaning mechanism 100 is as follows:

[0105] The cleaning mechanism 100 is first positioned on one side of the center-dividing fence 200. The height of the cleaning assembly 130 is then adjusted by the extension arm assembly 120 so that it is positioned at the starting stake 210 between two adjacent stakes 210 of the fence 200. The first drive member 133 drives the brush 132 to clean the center-dividing strip 300 between the two adjacent stakes 210, and the cleaning assembly 130 synchronously moves along the movement direction Y of the extension of the fence 200 until it reaches the ending stake 210. The cleaning assembly 130 then collides with the ending stake 210, and the adjustment member 135 adjusts the cleaning assembly 130 to rotate 180 degrees or deflect and return to its initial position. Finally, the above steps are repeated until the center-dividing strip 300 of the fence 200 is completely cleaned. The cleaning mechanism 100 is capable of cleaning the center-dividing strip 300 of the fence 200 and avoiding the stakes 210, with high cleaning efficiency, strong flexibility, and easy operation.

[0106] In one example of the present invention, the extension arm assembly 120 includes:

[0107] At least two extension arms 121 and at least two telescopic members 122, the at least two extension arms 121 are hingedly connected in sequence to form a first connection end 125 and a second connection end 126 arranged at the head and tail, the first connection end 125 is hingedly connected to the base 110, and the second connection end 126 is hingedly connected to the cleaning assembly 130, wherein at least one telescopic member 122 is connected between the base 110 and the extension arm 121 connected thereto, and at least another telescopic member 122 is connected between two adjacent extension arms 121;

[0108] It is understood that the extension arm assembly 120 adjusts the height, so the extension arm 121 and the base 110 and the two adjacent extension arms 121 are all hinged up and down, and the telescopic member 122 is placed on the upper end or lower end of the base 110 and the extension arm 121 or the two adjacent extension arms 121; for example, Figure 1 As shown, the extension arms 121 include two and the telescopic members 122 include two. One telescopic member 122 (connected between the base 110 and the first extension arm 121) is located at the lower end, while the other telescopic member 122 (connected between two adjacent extension arms 121) is located at the upper end. In other words, the telescopic movement of the telescopic member 122 adjusts the rotation angle of the corresponding extension arm 121, thereby achieving height adjustment.

[0109] That is, the angle of each extension arm 121 is adjusted by a telescopic member 122 , so that the second connecting end 126 can move within a larger range, thereby improving the adjustment flexibility of the cleaning assembly 130 .

[0110] It should be noted that the hinges of two adjacent extension arms 121 and the hinges between the extension arms 121 and the base 110 can swing in the up and down directions, so that the cleaning component 130 can adjust its position in the height direction G, so that the cleaning component 130 can move to the lower end of the fence 200, thereby improving the movement flexibility of the cleaning component 130.

[0111] For example, the telescopic member 122 is one of a hydraulic cylinder, a pneumatic cylinder, and an electric push rod.

[0112] In one embodiment of the present invention, the extension arm assembly 120 includes a lifting device and an extension arm 121 connected thereto. The extension arm 121 is connected to the cleaning assembly 130. The extension arm 121 is configured to be height-adjustable by the extension device. For example, the extension arm 121 may be a hydraulic cylinder. In other words, the extension arm assembly 130 can be directly raised and lowered by the lifting device to adjust its height to suit different application environments.

[0113] In one example of the present invention, the extension arm assembly 120 further includes:

[0114] A connecting arm 123, one end of which is pivotally connected to the second connecting end 126, and the other end of which is connected to the cleaning assembly 130; wherein a limiter 124 is provided between the connecting arm 123 and the extension arm 121, and the limiter 124 is configured to limit the relative position between the connecting arm 123 and the second connecting end 126;

[0115] By adding the connecting arm 123, on the one hand, the effective length of the long extension arm assembly 120 can be extended to a larger range of movement of the cleaning assembly 130, thereby facilitating the cleaning of the cleaning assembly 130; and the pivotable connection between the connecting arm 123 and the second connecting end 126 can facilitate the folding of the connecting arm 123, thereby facilitating the storage and transportation of the cleaning assembly 130. When the cleaning assembly 130 performs the cleaning action, the limiting member 124 fixes the connecting arm 123 and the extension arm 121 to stabilize the cleaning assembly 130 connected to the connecting arm 123, thereby preventing the cleaning assembly 130 from swinging during the cleaning process.

[0116] In one example of the present invention, Figure 8 As shown, the limiting member 124 includes:

[0117] The limiting plate 1241 is located on the side of the extension arm assembly 120 close to its moving direction Y, and has a first limiting end 12411 and a second limiting end 12412, and the first limiting end 12411 is fixedly connected to the second connecting end 126, and the second limiting end 12412 is abutted against the connecting arm 123, and is used to limit the angle A between the connecting arm 123 and the extension arm 121; wherein, the angle A is less than 180 degrees.

[0118] That is to say, the extension arm 121 and the connecting arm 123 are hingedly connected by a connecting plate, so that the connecting arm 123 can swing back and forth relative to the extension arm 121. By setting a limit plate 1241, the angle between the connecting arm 123 and the extension arm 121 can be limited, so that the cleaning assembly 130 will not swing to an unbalanced position, that is, a position where the angle A is greater than or equal to 180 degrees.

[0119] For example, the first limiting end 12411 and the connecting arm 121 are fixed by strong magnetic adsorption, and a buffer rubber is provided on the second limiting end 12412 to buffer the impact force between the connecting arm 121 and the second limiting end 12412.

[0120] For example, the first limiting end 12411 and the second limiting end 12412 of the limiting plate 1241 are not on the same horizontal plane, thereby ensuring that the angle A between the connecting arm 123 and the extension arm 121 can be maintained within a range less than 180 degrees.

[0121] In one example of the present invention, the limiting member 124 further includes:

[0122] an elastic portion 1242 connected between the extension arm 121 and the connecting arm 123, and configured such that when the connecting arm 123 swings and the angle between the connecting arm 123 and the extension arm 121 is less than the angle A, the elastic portion 1242 is compressed and generates a force that tends to restore the connecting arm 123 to its initial position;

[0123] During the movement of the cleaning mechanism 100, when the connecting arm 123 swings backward under the action of the cleaning component 130, the elastic part 1242 will be squeezed at this time so that the elastic part 1242 can generate a tendency force to restore the connecting arm 123 to its original position, thereby maintaining the position of the connecting arm 123; when the cleaning component 130 collides with an obstacle, the connecting arm 123 will instantly be affected by the impact force and move backward, and the elastic part 1242 will also be squeezed at this time, so that it will generate a tendency force to restore the connecting arm 123 to its original position; by setting the elastic part 1242, the freedom of the connecting arm at the rear can be further limited, and it can have a certain buffering effect.

[0124] In short, the elastic part 1242 can enable the connecting arm 123 to be flexibly limited after swinging, so that once the cleaning component 130 collides, the impact force exerted on the connecting arm 123 will be buffered by the elastic part 1242, thereby protecting the connecting arm 123.

[0125] Preferably, the elastic portion 1242 is one of a compression spring, a spring, and an air spring.

[0126] Preferably, the angle A ranges from 170 to 175 degrees.

[0127] In one example of the present invention, the cleaning component 130 further includes:

[0128] a conveying member 134 , the conveying member 134 being installed between the first driving member 133 and the brush 132 and configured to cause the brush 132 to perform periodic reciprocating motion, wherein the brush 132 includes a plurality of brushes 132 , which are spaced apart and arranged on the conveying member 134 ;

[0129] That is to say, when the cleaning component 130 performs the cleaning action, the first driving member 133 drives the conveying member 134 to perform a periodic transmission motion, and the multiple brushes 132 are driven to perform a periodic reciprocating motion during the transmission motion of the conveying member 134, thereby realizing the cleaning of the center belt 300; by setting the conveying member 134, multiple brushes 132 can be driven to move at the same time, thereby greatly improving the cleaning efficiency of the cleaning component 130.

[0130] In one example of the present invention, the transmission member 134 includes:

[0131] The chain 1341 is rotatably connected to the chassis 131 via a sprocket 1342 , wherein a plurality of the brushes 132 are connected to the chain 1341 at intervals, and the first driving member 133 is connected to the sprocket 1342 ;

[0132] Specifically, there are two sprockets 1342, which are arranged at intervals on the chassis 131 (for example, along the transverse direction Z perpendicular to the moving direction Y of the cleaning component 130), and the chain 1341 is sleeved on the two sprockets 1342. The output shaft of the first driving member 133 is fixedly connected to the axle of one of the sprockets 1342, thereby driving the chain 1341 to perform periodic reciprocating motion along the sprocket 1342; wherein, the brush 132 is fixed on the chain 1341 at intervals along the extension direction of the chain 1341. During the periodic motion of the chain 1341, the brush 132 is also driven to perform periodic reciprocating motion, thereby more efficiently cleaning the ground of the center belt 300.

[0133] It can be understood that the moving direction Y, the lateral direction Z and the height direction G are perpendicular to each other.

[0134] In one example of the present invention, the transmission member 134 includes:

[0135] A conveyor belt is rotatably connected to the chassis 131 via a pulley, wherein a plurality of brushes 132 are connected to the conveyor belt at intervals, and the first driving member 133 is connected to the pulley;

[0136] Specifically, there are two pulleys, which are arranged at intervals on the chassis 131 (for example, along the transverse direction Z perpendicular to the moving direction Y of the cleaning component 130), the conveyor belt is mounted on the two pulleys, and the output shaft of the first driving member 133 is fixedly connected to the axle of one of the pulleys, thereby driving the conveyor belt to perform periodic reciprocating motion along the pulley; wherein, the brush 132 is fixed on the conveyor belt at intervals along the extension direction of the transmission belt, and during the periodic motion of the conveyor belt, the brush 132 is also driven to perform periodic reciprocating motion, thereby more efficiently cleaning the ground of the center belt 300.

[0137] In one example of the present invention, Figure 5 、 Figure 6 As shown, the transmission member 134 further includes: a first deceleration structure 1343, which includes:

[0138] The first driving tooth 13431 is fixedly connected to the output shaft of the first driving member 133;

[0139] The first driven tooth 13432 is fixedly connected to the sprocket 1342 or the pulley and meshes with the first driving tooth 13431;

[0140] The number of teeth of the first driving teeth 13431 is smaller than the number of teeth of the first driven teeth 13432 ;

[0141] That is to say, a first-stage reduction gear structure is also configured between the first driving member 133 and the sprocket 1342 or the pulley. Through the first reduction structure 1343, the output rotation of the first driving member 133 can be effectively reduced, so that the driven rotation of the sprocket 1342 or the pulley is more stable and the speed range of the chain 1341 is more reasonable.

[0142] It should be noted that, since the chain 1341 or the conveyor belt is in a continuous motion process, in order to facilitate the connection between the brush 132 and the chain 1341 or the conveyor belt, a connecting component needs to be added between the two.

[0143] The following is an example of chain 1341:

[0144] In one example of the present invention, the connection component includes:

[0145] Extension plate 1343 added to chain 1341;

[0146] A connecting plate 1321 fixedly connected to the brush 132;

[0147] The extension plate 1343 is provided with a plurality of first positioning holes, the connection plate 1321 is provided with a plurality of second positioning holes corresponding to and connected to the first positioning holes, and the fasteners are passed through the first positioning holes and the second positioning holes in sequence;

[0148] For example, Figure 6 As shown, the extension plate 1343 extends outward and folds (for example, folds 90 degrees) through the upper and lower end plates of two adjacent chain buckles, so that the connecting plate 1321 can be directly attached to the extension plate 1343, reducing the space occupied by the connecting component and making the whole more compact.

[0149] In one example of the present invention, the adjusting member 135 includes:

[0150] A sensing device 1351 is installed on the cleaning component 130 and is configured to sense the rotation angle information of the cleaning component 130;

[0151] The second driving member 1352 is coupled to the sensing member 1351 and is configured to drive the cleaning assembly 130 to rotate 180 degrees when sensing that the angle of the cleaning assembly 130 is deflected;

[0152] Specifically, during the cleaning process of the cleaning component 130, when the cleaning component 130 moves to the end stake 210 at the lower end of the fence 200, a collision occurs between the cleaning component 130 and the end stake 210, and the cleaning component 130 will be deflected. The sensing device 1351 senses the rotation angle of the cleaning component 130. When the rotation angle is greater than the preset rotation angle, the second driving component 1352 drives the cleaning component 130 to rotate 180 degrees, thereby avoiding the end stake 210, and the orientation of the cleaning component 130 does not change; the adjustment component 135 can facilitate the cleaning component 130 to avoid the stake 210, thereby greatly improving the cleaning efficiency of the cleaning component 130.

[0153] During the cleaning process of the cleaning assembly 130, vibration or other false triggering of the sensing device 1351 may occur. In this case, the cleaning assembly 130 may slightly deflect. In order to prevent the slight deflection from being detected by the sensing device and causing the cleaning assembly 130 to deflect, it is necessary to set the preset rotation angle to be greater than 0 degrees, for example, the preset rotation angle is 5 degrees. This can prevent the cleaning assembly 130 from rotating too sensitively.

[0154] In short, if Figure 10 As shown, the cleaning component 130 has two ends, a first end 1 and a second end 2, arranged in the transverse direction Z. The positions of the first end 1 and the second end 2 during the cleaning process between the first two adjacent fence piles 210 are rotated 180 degrees from the positions of the first end 1 and the second end 2 during the cleaning process between the next two adjacent fence piles 210.

[0155] It should be noted that a rotating shaft 136 is fixed to the chassis 131 of the cleaning assembly 130, and the rotating shaft 136 is pivotally connected to the connecting arm 123. The sensing device 1351 can be fixed to the rotating shaft 136 to measure the rotation angle information of the cleaning assembly 130;

[0156] In one example of the present invention, Figure 4 As shown, the adjusting member 135 further includes: a second deceleration structure 1353, which includes:

[0157] The second driving tooth 13531 is fixedly connected to the output shaft of the second driving member 1352;

[0158] The second driven tooth 13532 is fixedly connected to the rotating shaft 136 and meshes with the second driving tooth 13531;

[0159] The number of teeth of the second driving teeth 13531 is smaller than the number of teeth of the second driven teeth 13532 ;

[0160] That is to say, a first-stage reduction gear structure is also configured between the second driving member 1352 and the rotating shaft 136. Through the second reduction structure 1353, the output rotation of the second driving member 1352 can be effectively reduced, so that the driven rotation of the rotating shaft 136 is more stable and the speed range of the cleaning component 130 is more reasonable.

[0161] For example, the sensing device 1351 is an angle sensor;

[0162] In one example of the present invention, Figure 7 As shown, the adjusting member 135 includes:

[0163] a torsion spring 1354, which is sleeved on the rotating shaft 136 of the cleaning assembly 130 pivotally connected to the second connecting end 126, with one end of the torsion spring 1354 fixedly connected to the second connecting end 126 and the other end fixedly connected to the rotating shaft 136. When the cleaning assembly 130 touches an obstacle, the cleaning assembly 130 deflects, causing the torsion spring 1354 to generate a force tending to restore the cleaning assembly 130 to its initial position;

[0164] That is to say, during the cleaning process of the cleaning component 130, when the cleaning component 130 moves to the ending fence pile 210 at the lower end of the fence 200, a collision occurs between the cleaning component 130 and the ending fence pile 210, and the cleaning component 130 will be deflected. As the cleaning component 130 continues to move along the extension direction of the fence 200, the deflection angle of the cleaning component 130 becomes larger and larger until it reaches the near rotation angle. As the cleaning component 130 continues to move, the cleaning component 130 is separated from the fence pile 210, and the cleaning component 130 returns to its original position under the elastic force of the torsion spring 1354, and then continues to clean the next center strip 300 between the two fence piles 210; the above-mentioned transmission member 134 can make the cleaning component 130 and the connecting arm 123 flexibly connected, and use the deflection torque of the torsion spring 1354 to restore the cleaning component 130 to its original position after deflection, so as to cleverly avoid the fence pile 210. In addition, the structure is simple, easy to install, and highly reliable.

[0165] In short, if Figure 11 As shown, the cleaning component 130 has two ends, a first end 1 and a second end 2, arranged in the transverse direction Z. The positions of the first end 1 and the second end 2 during the cleaning process between the first two adjacent fence piles 210 do not change from the positions of the first end 1 and the second end 2 during the cleaning process between the next two adjacent fence piles 210.

[0166] In one example of the present invention, the auxiliary cleaning component 140 is further included, which includes:

[0167] An auxiliary arm 141, one end of which is connected to the extension arm 121;

[0168] The auxiliary cleaning disc 142 is pivotally connected to the other end of the auxiliary arm 141; wherein the auxiliary cleaning disc 142 includes: a third driving member 1421 and an auxiliary cleaning brush 1422 connected thereto;

[0169] The auxiliary arm 141 is disposed on one side of the cleaning assembly 130 and is located away from the movement direction of the cleaning assembly 130 .

[0170] Specifically, when the brush 132 of the cleaning component 130 cleans along the moving direction Y, the dust located at the center dividing belt 300 at the lower end of the fence 200 is cleaned to the road surface on both sides of the center dividing belt 300, and the auxiliary cleaning disc 142 can effectively clean the dust cleaned by the cleaning component 130, further improving the cleaning efficiency of the cleaning component 130.

[0171] In one example of the present invention, the auxiliary cleaning component 140 further includes:

[0172] an auxiliary telescopic member 143 , disposed between the auxiliary arm 141 and the extension arm 121 , and configured to adjust the angle between the auxiliary arm 141 and the extension arm 121 through telescopic movement;

[0173] By setting the auxiliary telescopic member 143, the angle between the auxiliary arm 141 and the extension arm 121 can be effectively adjusted, thereby facilitating the adjustment of the position of the auxiliary cleaning disc 142, making it more flexible when cleaning the center strip 300 at the fence 200, and greatly improving its adaptability.

[0174] In one example of the present invention, the controller 160 is further included.

[0175] The controller 160 is coupled to the extension arm assembly 120 and is configured to adjust the position of the extension arm assembly 120 in the height direction G;

[0176] The controller 160 is coupled to the cleaning assembly 130 and is configured to control the first driving member 133 to drive the brush 132 to move periodically and rotate 180 degrees from the initial position or deflect and return to the initial position after the cleaning assembly 130 encounters an obstacle.

[0177] Here, the adjustment member 135 is used as the sensing member 1351 and the second driving member 1352 as an example for detailed description: (The adjustment member 135 is coupled to the controller 160)

[0178] First, the cleaning mechanism 100 is configured to be on one side of the fence 200 with the center dividing belt 300. Then, the controller 160 controls the extension arm assembly 120 to adjust the height position of the cleaning assembly 130 so that it can be located at the starting stake 210 between two adjacent stakes 210 of the fence 200. The controller 160 controls the first driving member 133 to drive the brush 132 to clean the center dividing belt 300 between the two adjacent stakes 210, and the cleaning assembly 130 moves synchronously along the moving direction Y extending from the fence 200 to the starting stake 210. The cleaning assembly 130 then collides with the terminating stake 210. The sensing device 1351 senses that the rotation angle of the cleaning assembly 130 is greater than a preset rotation angle. The controller 160 controls the second driving member 1352 to rotate the cleaning assembly 130 180 degrees, causing the cleaning assembly 130 to avoid the terminating stake 210 and continue cleaning the median strip 300 between the next two stakes 210. The above steps are repeated until the cleaning of the fence 200 is complete. The cleaning mechanism 100 is capable of cleaning the median strip 300 of the fence 200 and avoiding the stakes 210, with high cleaning efficiency, strong flexibility, and easy operation.

[0179] According to a second aspect of the present invention, a vehicle, Figure 10 、 Figure 11 Shown, including:

[0180] Vehicle body;

[0181] As described above, the cleaning mechanism 100, wherein the base 110 is fixedly connected to the vehicle body;

[0182] The cleaning mechanism 100 is fixedly connected to the front end of the vehicle body, and the vehicle body is configured as a side of the fence 200 with a center dividing strip 300. Then, the controller 160 controls the extension arm assembly 120 to adjust the height position of the cleaning assembly 130 so that it can be located at the starting pile 210 between two adjacent piles 210 of the fence 200; the controller 160 controls the first driving member 133 to drive the brush 132 to clean the center dividing strip 300 between the two adjacent piles 210. At the same time, the vehicle body moves along the moving direction Y extending from the fence 200 to clean the center dividing strip 300. During the cleaning process, the cleaning assembly 130 is driven to move synchronously until it reaches the end stake 210. Then, the cleaning assembly 130 collides with the end stake 210. The sensing device 1351 senses that the rotation angle of the cleaning assembly 130 is greater than the preset rotation angle. The controller 160 controls the second driving member 1352 to rotate the cleaning assembly 130 180 degrees, allowing the cleaning assembly 130 to avoid the end stake 210 and continue to clean the median strip 300 between the next two stakes 210. Finally, the above steps are repeated until the cleaning of the fence 200 is completed. The vehicle can clean the median strip 300 of the fence 200 and avoid the stakes 210, with high cleaning efficiency, strong flexibility, and easy operation.

[0183] In one example of the present invention, it further includes:

[0184] The barrier 150 is provided on the vehicle body and corresponds to the cleaning assembly 130 , and is configured to prevent the cleaning assembly 130 from splashing dust during the cleaning process, thereby greatly improving the safety of the vehicle.

[0185] According to a third aspect of the present invention, a cleaning method of the cleaning mechanism 100 as described above is as follows: Figure 12 As shown, the following steps are included:

[0186] S10: The extension arm assembly 120 adjusts the height of the cleaning assembly 130 so that the cleaning assembly 130 is located at the starting stake 210 between two adjacent stakes 210 of the fence 200;

[0187] S20: The first driving member 133 drives the brush 132 to clean the dividing strip 300 between two adjacent fence piles 210, and the cleaning assembly 130 moves along the moving direction Y of the fence 200 until it ends at the fence pile 210;

[0188] S30: The cleaning assembly 130 collides with the termination pile 210, and the adjusting member 135 adjusts the cleaning assembly 130 to rotate 180 degrees or to return to the initial position after rotation.

[0189] S40: Repeat the above steps S10 to S30 to clean the center strip 300 between the next two adjacent fence stakes 210 until the center strip 300 at the fence 200 is cleaned.

[0190] That is, the cleaning mechanism 100 is first positioned on one side of the fence 200 with the center dividing strip 300. The extension arm assembly 120 is then used to adjust the height of the cleaning assembly 130 so that it is positioned at the starting stake 210 between two adjacent stakes 210 of the fence 200. The first driving member 133 drives the brush 132 to clean the center dividing strip 300 between the two adjacent stakes 210, and the cleaning assembly 130 moves synchronously along the movement direction Y of the extension of the fence 200 until it reaches the ending stake 210. The cleaning assembly 130 then collides with the ending stake 210, and the adjusting member 135 adjusts the cleaning assembly 130 to rotate 180 degrees or return to its initial position after rotation, thereby passing over the stake 210. Finally, the above steps are repeated until the center dividing strip 300 of the fence 200 is completely cleaned. This cleaning method can clean the center dividing strip 300 of the fence 200 while avoiding the stakes 210, and has high cleaning efficiency, strong flexibility, and easy operation.
