Description

Technical Field

[0001] The present invention relates to the technical field of environmental sanitation, and particularly relates to a cleaning device for a road pollution removal vehicle and a road pollution removal vehicle. Background Art

[0002] As a special vehicle for road cleaning, the road pollution removal vehicle is huge in size, but only a very small part, that is, the cleaning device, directly operates on the ground. Therefore, an intelligent and efficient cleaning device will directly affect the performance of the whole vehicle.

[0003] The high-pressure jet of the cleaning device is divided into several discs (hereinafter referred to as cleaning subsystems), and each cleaning subsystem is fixedly covered with a certain width of the road surface. All the cleaning subsystems together cover all the cleaning widths, and the cleaning subsystems are seamlessly docked at the critical zone.

[0004] From the test and practical situations, the current cleaning effect of the road pollution removal vehicle is already very good and can reach the level of "measuring cleanliness by grams". However, the cleaning device still has the following problems:

[0005] 1. Each cleaning subsystem can cover and only cover a certain width of the road surface. If a certain cleaning subsystem fails to work or affects the cleaning effect, then the cleaning subsystem must be maintained before operation, which directly affects the operation progress.

[0006] 2. Each cleaning subsystem either works entirely or stops working entirely, that is, at a certain time point, the states of all cleaning subsystems are exactly the same, which is too rigid and cannot cope with various working conditions. For example, if the road is 6 meters wide in total, the cleaning device is 2.5 meters wide, and each cleaning subsystem covers a width of 0.5 meters, and there are 5 cleaning subsystems (5 * 0.5 = 2.5), then after two operations, 5 meters of the 6-meter road has been cleaned, and the remaining 1 meter of the road has not been cleaned. If the operation continues at this time and the cleaning device still operates according to covering 2.5 meters, then the extra 1.5 meters will be operated twice, wasting resources.

[0007] 3. The rotating jet pressures of different cleaning subsystems are the same, while the cleaning degrees of different places on a section of the road surface are different. For example, under normal circumstances, the dust accumulation amount at the road edge is more. In some sections, due to special reasons, the dust accumulation amount in some places is large or there is oil stain, and a greater rotating jet pressure is required for impact. With the same jet pressure, it may be possible to completely wash out the dust on the left side of the road surface, while there will be a little residue on the right side. If the high-pressure rotating jet pressure of different cleaning subsystems can be adjusted according to the actual situation, a better operation effect will be achieved. Summary of the Invention

[0008] For this reason, it is necessary to provide a cleaning device for a road pollution cleaning vehicle and a road pollution cleaning vehicle to solve the problem that when a certain cleaning subsystem fails to work, it is necessary to repair the cleaning subsystem first, which affects the operation efficiency.

[0009] To achieve the above object, the inventor provides a cleaning device for a road pollution cleaning vehicle, including a base and a plurality of cleaning subsystems;

[0010] A transverse movement mechanism is provided on the base, and the transverse movement mechanism is used to adjust the position of the cleaning subsystem on the base;

[0011] The cleaning subsystem includes a rotary water spraying mechanism, and the rotary water spraying mechanism includes a rotary spray rod, a rotary joint and rotary nozzles; the rotary spray rod is rotatably installed on the transverse movement mechanism of the base through the rotary joint, there are two rotary nozzles, which are respectively arranged at both ends of the rotary spray head, the rotary nozzles are all inclined downward, and the orientations of the two rotary nozzles are cross - arranged.

[0012] Further optimization, the transverse movement mechanism includes a cross bar, a limiting mechanism and sliders;

[0013] There are a plurality of the sliders, which are slidably arranged on the cross bar;

[0014] The limiting mechanism is used to limit the position of the sliders on the cross bar;

[0015] The rotary spray rod is arranged on the slider of the transverse movement mechanism through the rotary joint.

[0016] Further optimization, the limiting mechanism includes a limiting bolt,

[0017] A plurality of limiting holes are arranged on the cross bar;

[0018] The slider is installed in the limiting hole on the cross bar through the limiting bolt.

[0019] Further optimization, a dust - blocking disc and a disc support are also provided on the cleaning subsystem;

[0020] The dust - blocking disc is installed on the rotary spray rod through the disc support.

[0021] Further optimization, the rotary spray rod includes a fixed rod, a first telescopic rod and a second telescopic rod, the first telescopic rod is telescopically arranged at one end of the fixed rod, the second telescopic rod is telescopically arranged at the other end of the fixed rod, and the fixed rod is arranged on the transverse movement mechanism through the rotary joint;

[0022] There are two rotary nozzles, which are respectively arranged on the first telescopic rod and the second telescopic rod.

[0023] Further optimization, it further includes a fault detection system, a control valve and a control system;

[0024] There are multiple control valves, which are respectively arranged between each cleaning subsystem and the high-pressure jet system, and the control ends of the control valves are connected to the control system;

[0025] The control system is used to control the working states of the respective cleaning subsystems through the control valves.

[0034] Different from the prior art, in the above technical solution, the cleaning subsystem cleans the road through a rotating water spraying mechanism. After the high-pressure water flow enters the rotating spray bar through the rotary joint, it sprays out from the rotating water spray nozzles at both ends of the rotating spray bar to clean the road surface. Since the orientations of the two rotating nozzles are cross-set and inclined, under the action of the high-pressure water jet, the rotating spray bar will be driven to rotate around the rotary joint, and the ground can be cleaned by rotation; when a certain cleaning subsystem fails and cannot work, or the cleaning effect is not good, the horizontal movement mechanism is used to re-adjust the positions of the respective cleaning subsystems on the base and adjust the working range of the cleaning subsystems that can work normally, so that the remaining cleaning subsystems can still clean the road surface, avoiding the problem that when a certain cleaning subsystem fails and cannot clean the road surface, it is necessary to repair the cleaning subsystem first, which affects the operation efficiency.

[0044] To explain in detail the technical content, structural features, achieved objectives and effects of the technical solution, the following is a detailed description in conjunction with specific embodiments and with reference to the accompanying drawings.

[0045] Please refer to Figure 1-2 , this embodiment provides a cleaning device for a road pollution removal vehicle, including a base 110 and several cleaning subsystems;

[0046] A transverse movement mechanism is provided on the base 110, and the transverse movement mechanism is used to adjust the position of the cleaning subsystem on the base 110;

[0047] The cleaning subsystem includes a rotating water spraying mechanism, and the rotating water spraying mechanism includes a rotating spray bar 121, a rotating joint 123 and a rotating nozzle 122; the rotating spray bar 121 is rotatably installed on the transverse movement mechanism of the base 110 through the rotating joint 123, there are two rotating nozzles 122, which are respectively arranged at both ends of the rotating spray head, the rotating nozzles 122 are both inclined downward, and the orientations of the two rotating nozzles 122 are cross - arranged.

[0048] The cleaning subsystem cleans the road through a rotating water spraying mechanism. After high-pressure water flow enters the rotating spray bar 121 through the rotary joint 123, it sprays out from the rotating water sprays at both ends of the rotating spray bar 121 to clean the road surface. Since the orientations of the two rotating nozzles 122 are cross-set and inclined, under the action of the high-pressure water jet, the rotating spray bar 121 will be driven to rotate around the rotary joint 123, and can rotate to clean the ground. When a certain cleaning subsystem fails and cannot work, or the cleaning effect is not good, the transverse movement mechanism is used to re-adjust the positions of the cleaning subsystems on the base 110, and adjust the working range of the cleaning subsystems that can work normally, so that the remaining cleaning subsystems can still clean the road surface, avoiding the problem that when a certain cleaning subsystem fails and cannot clean the road surface, it is necessary to repair the cleaning subsystem first, which affects the operation efficiency. As Figure 4 described, there were originally five cleaning subsystems. When one of the cleaning subsystems fails, the remaining four cleaning subsystems can work. The positions of the remaining four cleaning subsystems are adjusted through the transverse movement mechanism, so that the cleaning ranges of the four cleaning subsystems are the same as those of the original five cleaning subsystems, ensuring that the coverage area does not change when the number of cleaning subsystems decreases.

[0049] In this embodiment, in order to facilitate the position adjustment of each cleaning subsystem, the transverse movement mechanism includes a cross bar 111, a limiting mechanism and a slider 112;

[0050] There are several sliders 112, which are slidably arranged on the cross bar 111;

[0051] The limiting mechanism is used to limit the position of the slider 112 on the cross bar 111;

[0052] The rotating spray bar is arranged on the slider 112 of the transverse movement mechanism through the rotary joint 123.

[0053] When it is necessary to adjust the position of the cleaning subsystem on the base 110, first, release the restriction on the slider 112 corresponding to the corresponding cleaning subsystem through the limiting mechanism, and adjust it to the corresponding position. Then, re-restrict the slider 112 through the limiting mechanism, thereby realizing the position adjustment of the cleaning subsystem. Among them, the limiting mechanism includes a limiting bolt 113, and a number of limiting holes are provided on the cross bar 111; the slider 112 is installed in the limiting hole on the cross bar 111 through the limiting bolt 113. The slider 112 is installed on the limiting hole on the cross bar 111 through the limiting bolt 113. When it is necessary to adjust the position of the cleaning subsystem, the slider 112 corresponding to the cleaning subsystem is detached from the current limiting hole on the cross bar 111, and then slid to the limiting hole corresponding to the position to be adjusted. Then, the cleaning subsystem is fixed on the limiting hole corresponding to the adjusted position through the limiting bolt 113, realizing the position adjustment of the cleaning subsystem, which is simple, convenient, and firmly installed.

[0054] In this embodiment, in order to prevent the high-pressure water sprayed by the rotating nozzle 122 from rebounding hard objects such as crushed stones or broken glass and causing damage to the rotating spray bar 121 or the rotating nozzle 122, etc.; a dust-proof disc 124 and a disc bracket are further provided on the cleaning subsystem; the dust-proof disc 124 is installed on the rotating spray bar 121 through the disc bracket. By installing the dust-proof disc 124 on the rotating spray bar 121 through the disc bracket, the dust-proof disc 124 rotates with the rotating spray bar 121. When the high-pressure water rebounds hard objects such as crushed stones or broken glass, the rotating water spraying mechanism can be effectively protected by the dust-proof disc 124 and the normal operation of the rotating water spraying mechanism can be ensured, improving the service life.

[0055] In this embodiment, in order to improve the working range of the cleaning subsystem after adjusting the position when a certain cleaning subsystem fails, the rotating spray bar 121 includes a fixed rod, a first telescopic rod and a second telescopic rod. The first telescopic rod is telescopically arranged at one end of the fixed rod, and the second telescopic rod is telescopically arranged at the other end of the fixed rod. The fixed rod is arranged on the transverse movement mechanism through a rotary joint 123; there are two rotating nozzles 122, which are respectively arranged on the first telescopic rod and the second telescopic rod. When it is necessary to adjust the cleaning range of the cleaning subsystem, the spraying range of the rotating nozzle 122 is adjusted by adjusting the telescopic amounts of the first telescopic rod and the second telescopic rod. In other embodiments, the spraying range of the rotating nozzle 122 can also be adjusted by adjusting the inclination angle between the rotating nozzle 122 and the rotating spray bar 121.

[0056] Please refer to Figure 4, in this embodiment, when the entire cleaned road surface exceeds the width of the cleaning device and the remaining road surface to be cleaned is less than the width of the cleaning device, in order to reduce resource waste, a control valve 220 and a control system 210 are further included; a plurality of the control valves 220 are respectively arranged between each cleaning subsystem and the high-pressure jet system, and the control end of the control valve 220 is connected to the control system 210; the control system 210 is used to control the working state of each cleaning subsystem through the control valve 220. After cleaning the cleaned road surface, when the remaining cleaned road surface is less than the width of the cleaning device, the number of corresponding cleaning subsystems is adjusted according to the remaining cleaned road surface. For example, when only two cleaning subsystems are needed to work on the remaining cleaned road surface, the control system 210 makes the corresponding two cleaning subsystems work through the control valve to clean the remaining road surface, while making the other cleaning subsystems not work, reducing resource waste. For example, if the cleaning device includes 5 cleaning subsystems and the working range of each cleaning subsystem is a diameter of 0.5 meters, then the entire cleaning width of the cleaning device is 2.5 meters. When the remaining cleaned road surface is 1.0 meter, only the corresponding two cleaning subsystems need to work, and the remaining three cleaning subsystems stop working.

[0057] In this embodiment, when a certain cleaning subsystem fails and cannot work properly, to avoid continuing to supply high-pressure water to this cleaning subsystem, resulting in resource waste or aggravating the failure of this cleaning subsystem, a fault detection system 230 is further included, and the fault detection system 230 is connected to the control system 210;

[0058] The fault detection system 230 is used to detect the fault state of each cleaning subsystem and send the fault state of each cleaning subsystem to the control system 210;

[0059] The control system 210 is further used to control this cleaning subsystem to stop working through the control valve 220 when the cleaning subsystem fails.

[0060] The fault detection system 230 detects the fault status of each cleaning subsystem. When a fault in a certain cleaning subsystem is detected by the fault detection module, the control system 210 controls the operation of the cleaning subsystem through the control valve, that is, disconnects the high-pressure jet system from providing high-pressure water flow to the cleaning subsystem. Among them, when a fault in a certain cleaning subsystem is detected by the fault detection system 230, an alarm signal is issued, enabling the staff to re-adjust the position of the cleaning subsystem through the traversing mechanism so that the cleaning system can continue to operate. Among them, the fault detection system 230 includes rotational speed detection sensors arranged on each rotating spray bar 121. By detecting the rotational speed of the rotating spray bar 121 through the rotational speed detection sensors, it is determined whether a fault occurs in the cleaning subsystem. When the rotational speed of the rotating spray bar 121 is lower than the preset speed, it can be determined that a fault occurs in the cleaning subsystem. In other embodiments, other sensors can also be used to detect whether a fault occurs in each cleaning subsystem, such as water flow detection sensors, etc. By detecting the flow rate of the high-pressure water flow sprayed by the rotating nozzle 122, it is determined whether a fault occurs in the cleaning subsystem.

[0061] In this embodiment, in order to further improve the working effect of the cleaning device, it further includes a road condition detection system 240, a power adjustment system 250, and a control system 210; the road condition detection system 240 is used to detect the road condition of the road; the power adjustment system 250 is used to adjust the working power of each cleaning subsystem; the control system 210 is used to adjust the working power of each cleaning subsystem according to the road condition. By the road condition detection system 240, the road condition of the cleaning road is detected. According to the actual situation of the road, the control system 210 adjusts the working efficiency of each cleaning subsystem through the power adjustment system 250 to cope with the actual situation of the road surface cleaned by each cleaning subsystem. On the same ground, the cleaning effect of the high-pressure rotary jet only depends on the jet pressure and the action time. The greater the jet pressure and the longer the action time, the more obvious the impact effect, which is directly related to the power allocated to this cleaning subsystem. By adopting an AI algorithm, the actual situation of the road surface is collected by the road condition detection system 240. According to the actual situation of the ground to be cleared by the cleaning subsystem, the operation power is flexibly adjusted. For example, the general municipal road cleaning level is 3, the potholed road is 4, and the extreme road is 5. For example, the working power situation of a certain moment of five cleaning subsystems is as follows:

[0062] Level 3 Level 3 Level 3 Level 4 Level 3

[0063] And the working efficiency situation at the next moment is as follows:

[0064] Level 4 Level 3 Level 3 Level 3 Level 3

[0065] The working power of each cleaning subsystem can be flexibly adjusted to improve the effect of road cleaning. Among them, the road condition detection system 240 can be a camera. The road surface images are collected through the camera, and the control system 210 analyzes the conditions of each road surface through image recognition. Collecting road surface images through the camera and then performing image recognition on each condition of the road surface through the control system 210 is a conventional technology in this field and has not been improved.

[0066] In another embodiment, a road pollution cleaning vehicle includes a cleaning device. The cleaning device includes a base 110 and a plurality of cleaning subsystems.

[0067] A transverse movement mechanism is provided on the base 110, and the transverse movement mechanism is used to adjust the position of the cleaning subsystem on the base 110.

[0068] The cleaning subsystem includes a rotating water spraying mechanism. The rotating water spraying mechanism includes a rotating spray rod 121, a rotating joint 123, and rotating nozzles 122. The rotating spray rod 121 is rotatably installed on the transverse movement mechanism of the base 110 through the rotating joint 123. There are two rotating nozzles 122, which are respectively arranged at both ends of the rotating spray head. The rotating nozzles 122 are both inclined downward, and the orientations of the two rotating nozzles 122 are cross-set.

[0069] The cleaning subsystem cleans the road through the rotating water spraying mechanism. After the high-pressure water flow enters the rotating spray rod 121 through the rotating joint 123, it sprays out from the rotating water sprays at both ends of the rotating spray rod 121 to clean the road surface. Since the orientations of the two rotating nozzles 122 are cross-set and inclined, under the action of the high-pressure water jet, it will drive the rotating spray rod 121 to rotate around the rotating joint 123, and can rotate to clean the ground. When a certain cleaning subsystem fails and cannot work, or the cleaning effect is not good, the transverse movement mechanism is used to re-adjust the positions of each cleaning subsystem on the base 110, and adjust the working range of the cleaning subsystems that can work normally, so that the remaining cleaning subsystems can still clean the road surface, avoiding the problem that when a certain cleaning subsystem fails and the road surface cannot be cleaned, it is necessary to repair the cleaning subsystem first, which affects the operation efficiency.

[0070] In this embodiment, in order to facilitate the position adjustment of each cleaning subsystem, the transverse movement mechanism includes a cross bar 111, a limiting mechanism, and a slider 112.

[0071] There are a plurality of sliders 112, which are slidably arranged on the cross bar 111.

[0072] The limiting mechanism is used to limit the position of the slider 112 on the cross bar 111.

[0073] The fixed rod is arranged on the slider 112 of the transverse movement mechanism through a rotary joint 123.

[0074] When it is necessary to adjust the position of the cleaning subsystem on the base 110, first, release the restriction on the corresponding slider 112 of the cleaning subsystem through the limiting mechanism, and adjust it to the corresponding position. Then, restrict the slider 112 again through the limiting mechanism, thereby realizing the position adjustment of the cleaning subsystem. Among them, the limiting mechanism includes a limiting bolt 113, and a number of limiting holes are arranged on the cross bar 111; the slider 112 is installed in the limiting hole on the cross bar 111 through the limiting bolt 113. The slider 112 is installed in the limiting hole on the cross bar 111 through the limiting bolt 113. When it is necessary to adjust the position of the cleaning subsystem, remove the corresponding slider 112 of the cleaning subsystem from the current limiting hole on the cross bar 111, then slide it to the limiting hole corresponding to the position to be adjusted, and then fix the cleaning subsystem on the limiting hole corresponding to the adjusted position through the limiting bolt 113, realizing the position adjustment of the cleaning subsystem, which is simple, convenient, and firmly installed.

[0075] In this embodiment, in order to prevent the high-pressure water sprayed by the rotary nozzle 122 from rebounding hard objects such as broken stones or broken glass and causing damage to the rotary spray rod 121 or the rotary nozzle 122, etc.; a dust-proof disc and a disc bracket are also provided on the cleaning subsystem; the dust-proof disc is installed on the rotary spray rod 121 through the disc bracket. By installing the dust-proof disc 124 on the rotary spray rod 121 through the disc bracket, the dust-proof disc 124 rotates with the rotary spray rod 121. When the high-pressure water rebounds hard objects such as broken stones or broken glass, the rotary water spraying mechanism can be effectively protected by the dust-proof disc 124 and the normal operation of the rotary water spraying mechanism can be ensured, improving the service life.

[0076] In this embodiment, in order to improve the working range of the cleaning subsystem after adjusting the position when a certain cleaning subsystem fails, the rotary spray rod 121 includes a fixed rod, a first telescopic rod and a second telescopic rod. The first telescopic rod is telescopically arranged at one end of the fixed rod, and the second telescopic rod is telescopically arranged at the other end of the fixed rod. The fixed rod is arranged on the transverse movement mechanism through a rotary joint 123; there are two rotary nozzles 122, which are respectively arranged on the first telescopic rod and the second telescopic rod. When it is necessary to adjust the cleaning range of the cleaning subsystem, by adjusting the telescopic amounts of the first telescopic rod and the second telescopic rod, the spraying range of the rotary nozzle 122 is adjusted. In other embodiments, the spraying range of the rotary nozzle 122 can also be adjusted by adjusting the inclination angle between the rotary nozzle 122 and the rotary spray rod 121.

[0077] In this embodiment, when the entire cleaned road surface exceeds the width of the cleaning device, while the remaining road surface to be cleaned is less than the width of the cleaning device, in order to reduce resource waste, a control valve 220 and a control system 210 are further included; a plurality of the control valves 220 are respectively arranged between each cleaning subsystem and the high-pressure jet system, and the control end of the control valve 220 is connected to the control system 210; the control system 210 is used to control the working state of each cleaning subsystem through the control valve 220. After cleaning the cleaned road surface, when the remaining cleaned road surface is less than the width of the cleaning device, the number of corresponding cleaning subsystems is adjusted according to the remaining cleaned road surface for operation. For example, when only two cleaning subsystems are required to operate for the remaining cleaned road surface, the control system 210 controls the corresponding two cleaning subsystems to operate through the control valve to clean the remaining road surface, while making the other cleaning subsystems not work, reducing resource waste. For example, if the cleaning device includes 5 cleaning subsystems, and the working range of each cleaning subsystem is a diameter of 0.5 meters, then the entire cleaning width of the cleaning device is 2.5 meters. When the remaining cleaned road surface is 1.0 meter, only the corresponding two cleaning subsystems are required to operate, and the remaining three cleaning subsystems stop working.

[0078] In this embodiment, when a certain cleaning subsystem fails and cannot work properly, to avoid continuing to supply high-pressure water to this cleaning subsystem, resulting in resource waste or aggravating the failure of this cleaning subsystem, a fault detection system 230 is further included, and the fault detection system 230 is connected to the control system 210;

[0079] The fault detection system 230 is used to detect the fault states of each cleaning subsystem and send the fault states of each cleaning subsystem to the control system 210;

[0080] The control system 210 is further used to control this cleaning subsystem to stop working through the control valve 220 when a cleaning subsystem fails.

[0081] The fault detection system 230 detects the fault status of each cleaning subsystem. When a fault in a certain cleaning subsystem is detected by the fault detection module, the control system 210 controls the operation of the cleaning subsystem through the control valve, that is, disconnects the high-pressure jet system from providing high-pressure water flow to the cleaning subsystem. Among them, when a fault in a certain cleaning subsystem is detected by the fault detection system 230, an alarm signal is issued, enabling the staff to re-adjust the position of the cleaning subsystem through the traversing mechanism so that the cleaning system can continue to operate. Among them, the fault detection system 230 includes rotation speed detection sensors arranged on each rotating spray bar 121. The rotation speed of the rotating spray bar 121 is detected by the rotation speed detection sensors to determine whether a fault occurs in the cleaning subsystem. When the rotation speed of the rotating spray bar 121 is lower than the preset speed, it can be determined that a fault occurs in the cleaning subsystem. In other embodiments, other sensors can also be used to detect whether a fault occurs in each cleaning subsystem, such as a water flow detection sensor, etc. Whether a fault occurs in the cleaning subsystem is determined by detecting the flow rate of the high-pressure water flow sprayed by the rotating nozzle 122.

[0082] In this embodiment, in order to further improve the working effect of the cleaning device, it further includes a road condition detection system 240, a power adjustment system 250 and a control system 210; the road condition detection system 240 is used to detect the road conditions; the power adjustment system 250 is used to adjust the working power of each cleaning subsystem; the control system 210 is used to adjust the working power of each cleaning subsystem according to the road conditions. The road condition detection system 240 detects the road conditions of the cleaning road surface. According to the actual situation of the road, the control system 210 adjusts the working efficiency of each cleaning subsystem through the power adjustment system 250 to cope with the actual situation of the road surface cleaned by each cleaning subsystem. On the same ground, the cleaning effect of the high-pressure rotary jet only depends on the jet pressure and the action time. The greater the jet pressure and the longer the action time, the more obvious the impact effect, which is directly related to the power allocated to this cleaning subsystem. By adopting an AI algorithm, the road condition detection system 240 collects the actual situation of the road surface. According to the actual situation of the ground to be cleared by the cleaning subsystem, the operation power is flexibly adjusted. For example, the general municipal road surface cleaning is level 3, the potholed road surface is level 4, and the extreme road surface is level 5. The working power situation of a certain moment of five cleaning subsystems is as follows:

[0083] Level 3 Level 3 Level 3 Level 4 Level 3

[0084] And the working efficiency situation at the next moment is as follows:

[0085] Level 4 Level 3 Level 3 Level 3 Level 3

[0086] The working power of each cleaning subsystem can be flexibly adjusted to improve the effect of road cleaning. Among them, the road condition detection system 240 can be a camera, which collects road pictures through the camera. The control system 210 analyzes the conditions of each road surface through picture recognition. Among them, collecting road pictures through the camera and then performing image recognition on each condition of the road surface by the control system 210 is a conventional technology in this field and has not been improved.

[0087] In another embodiment, the road pollution removal vehicle can be a fully autonomous vehicle, which can control each subsystem automatically according to the actual conditions of the road to clean the road.
