DETAILED DESCRIPTION

[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The utility model proposes a cleaning system 1000, wherein a main cleaning vehicle 100 cooperates with an auxiliary cleaning vehicle 200 to place and release the auxiliary cleaning vehicle 200, thereby transferring the auxiliary cleaning vehicle 200, making it convenient for the auxiliary cleaning vehicle 200 to clean subway entrances, urban underground passages and other areas, thereby improving operating efficiency and reducing labor intensity.

[0040] According to the cleaning system 1000 in the embodiment of the present invention, the cleaning system 1000 includes a main cleaning vehicle 100 and an auxiliary cleaning vehicle 200 .

[0041] Reference Figures 1 to 5 According to the main cleaning vehicle 100 in the embodiment of the utility model, the main cleaning vehicle 100 can travel on the road. The main cleaning vehicle 100 and the auxiliary cleaning vehicle 200 can be part of the cleaning system 1000. The cleaning system 1000 can be used to clean areas that are a certain distance from the road, such as subway entrances, underground passages, etc. Most of the floors in these areas are paved with tiles, marble, etc., and the bearing strength is limited. They cannot withstand the weight of the main cleaning vehicle 100. Therefore, it is necessary to use the lighter auxiliary cleaning vehicle 200 for cleaning. Since the auxiliary cleaning vehicle requires a lighter weight, it is impossible to load a mobile device with high mobility. Therefore, it is necessary to cooperate with the heavier main cleaning vehicle 100 for placing the auxiliary cleaning vehicle 200 to transfer the cleaning vehicle, so that with the cooperation of the main cleaning vehicle 100 and the auxiliary cleaning vehicle 200, areas such as subway entrances and urban underground passages are cleaned to improve the cleaning efficiency.

[0042] The main cleaning vehicle 100 may include a chassis 10 , a turning ladder 20 , and a water tank 30 .

[0043] Among them, a placement platform 11 is provided on the chassis 10 for placing the auxiliary cleaning vehicle 200, and a reversing ladder 20 is connected to the chassis 10. The reversing ladder 20 can be used to construct a driving channel corresponding to the placement platform 11, so that the auxiliary cleaning vehicle 200 can enter and exit the placement platform 11 conveniently. The water tank 30 is arranged on the chassis 10 and is used to connect the auxiliary cleaning vehicle 200 to replenish the cleaning liquid for the auxiliary cleaning vehicle 200; and the auxiliary cleaning vehicle 200 is suitable for being placed on the placement platform 11. The auxiliary cleaning vehicle 200 includes a body 240 and a cleaning component 220. The body 240 is placed on the placement platform 11 and can be driven away along the driving channel. The cleaning component 220 is arranged on the body 240 for cleaning the working surface, wherein the auxiliary cleaning vehicle 200 is connected to the water tank 30 on the main cleaning vehicle 100 through a waterway, so that it can be used for the placement and release of the auxiliary cleaning vehicle 200, so as to transfer the auxiliary cleaning vehicle 200, so as to facilitate the auxiliary cleaning vehicle 200 to clean subway entrances, urban underground passages and other areas, improve work efficiency, and reduce labor intensity.

[0044] Specifically, when the cleaning system 1000 needs to clean areas such as subway entrances and urban underground passages, the main cleaning vehicle 100 and the auxiliary cleaning vehicle 200 need to work separately; specifically, the auxiliary cleaning vehicle 200 can be placed on the placement platform 11, and the auxiliary cleaning vehicle 200 can be transferred by the main cleaning vehicle 100, and then the main cleaning vehicle 100 can be driven to a place on the road close to the area, and a driving channel corresponding to the placement platform 11 is constructed through the turning ladder 20 on the main cleaning vehicle 100. At this time, the auxiliary cleaning vehicle 200 on the placement platform 11 can leave the placement platform 11 through the driving channel, that is, it is lowered from the placement platform 11 to the road, and then the auxiliary cleaning vehicle 200 can be driven to areas such as subway entrances and urban underground passages, and perform cleaning operations on the area; after the auxiliary cleaning vehicle 200 completes the cleaning operation, it can drive to the main cleaning vehicle 100 and enter the placement platform 11 through the driving channel again, that is, the auxiliary cleaning vehicle 200 returns to the placement platform 11.

[0045] In addition, the auxiliary cleaning vehicle 200 generally performs operations by flushing, roller brush cleaning, etc., and thus needs to be replenished with cleaning liquid. Therefore, a water tank 30 may be provided on the chassis 10 of the main cleaning vehicle 100, and the water tank 30 may be used to connect the auxiliary cleaning vehicle 200 to replenish the cleaning liquid for the auxiliary cleaning vehicle 200; specifically, a water pump may be provided on the main cleaning vehicle 100, and when the auxiliary cleaning vehicle 200 is placed on the placement platform 11, the water tank 30 on the main cleaning vehicle 100 can be connected to the auxiliary cleaning vehicle 200, and the water pump drives the cleaning liquid in the water tank 30 to flow to the auxiliary cleaning vehicle 200. Washing the car 200 replenishes the cleaning liquid for the auxiliary cleaning car 200, which is convenient for the cleaning operation of the auxiliary cleaning car 200; on this basis, a water tank 260 can be provided on the auxiliary cleaning car 200, and the cleaning liquid on the main cleaning car 100 can be replenished into the water tank 260 of the auxiliary cleaning car 200 through the water system 50, which is convenient for the auxiliary cleaning car 200 and the main cleaning car 100 to work separately; or, the cleaning liquid on the main cleaning car 100 can be directly connected to the cleaning component 220 through the water system 50, which is convenient for the main cleaning car 100 and the auxiliary cleaning car 200 to work together.

[0046] Of course, when the cleaning system 1000 cleans an area close to the road, the main cleaning vehicle 100 and the auxiliary cleaning vehicle 200 do not need to operate separately. By connecting the water tank 30 of the main cleaning vehicle 100 with the auxiliary cleaning vehicle 200, sufficient cleaning liquid can be provided to the auxiliary cleaning vehicle 200. In other words, the operator can allow the cleaning system 1000 to operate separately or in combination according to actual conditions, thereby improving the applicability of the cleaning system 1000.

[0047] Therefore, according to the cleaning system 1000 in the embodiment of the utility model, the main cleaning vehicle 100 can cooperate with the auxiliary cleaning vehicle to be used for the placement and release of the auxiliary cleaning vehicle 200, thereby transferring the auxiliary cleaning vehicle 200, making it convenient for the auxiliary cleaning vehicle 200 to clean subway entrances, urban underground passages and other areas, thereby improving work efficiency and reducing labor intensity.

[0048] It should be added that the cleaning component 220 may include a contact cleaning module 225 and a non-contact cleaning module 226, wherein the contact cleaning module 225 can directly contact the surface to be cleaned and clean it by means of a brush, a wiping cloth, etc.; the non-contact cleaning module 226 can achieve the cleaning purpose by spraying high-pressure gas, liquid or other media.

[0049] Reference Figures 1 to 5 In some embodiments of the present invention, the reversible ladder 20 has an unfolded state and a stored state. The reversible ladder 20 is stored on the chassis 10 in the stored state. The reversible ladder 20 is unfolded relative to the chassis 10 in the unfolded state, and is configured to form a driving channel corresponding to the placement platform 11, which is used for the auxiliary cleaning vehicle 200 to enter and exit the placement platform 11; specifically, when the auxiliary cleaning vehicle 200 is placed on the placement platform 11, the reversible ladder 20 can be switched to the stored state, at which time the reversible ladder 20 is stored on the chassis 10. Compared with the situation where the reversible ladder 20 is unfolded when the auxiliary cleaning vehicle 200 does not need to be lowered, by accommodating the reversible ladder 20 on the chassis 10, the collision between the unfolded reversible ladder 20 and the external structure can be avoided; when it is necessary to operate, the reversible ladder 20 can be switched to the unfolded state, that is, the reversible ladder 20 is unfolded relative to the chassis 10, thereby constructing a driving channel corresponding to the placement platform 11. At this time, the auxiliary cleaning vehicle 200 can be lowered to the road surface through the driving channel, which is convenient for the auxiliary cleaning vehicle 200 to clean.

[0050] Regarding the configuration of the invertible ladder 20, the present invention provides the following embodiments for more detailed description:

[0051] Example 1

[0052] Reference Figures 1 to 5 The reversible ladder 20 is rotatably connected to the chassis 10 and is arranged in the driving direction when the auxiliary cleaning vehicle 200 leaves the placement platform 11, wherein, in the storage state, the reversible ladder 20 stands upright on the side of the placement platform 11, and; in other words, when the auxiliary cleaning vehicle 200 is placed on the placement platform 11, the reversible platform can be switched to the storage state, at which time the reversible ladder 20 can be used as a limiting structure, limited in the walking direction of the auxiliary cleaning vehicle 200 leaving the placement platform 11, and is used to limit the auxiliary cleaning vehicle 200 from leaving the placement platform 11, so as to ensure that the auxiliary cleaning vehicle 200 can be stably placed.

[0053] In addition, in the unfolded state, the reversible ladder 20 is connected to the chassis 10 and tilted downward in a direction away from the chassis 10, and the reversible ladder 20 has an angle with the surface of the placement platform 11 in the unfolded state, and the angle is in the range of 15° to 60°; it can be understood that the placement platform 11 on the main cleaning vehicle 100 has a certain height above the road surface, and the reversible ladder 20 has a connecting end connected to the chassis 10 and a free end away from the chassis 10. Therefore, when the reversible ladder 20 switches to the unfolded state, the reversible ladder 20 can tilt downward in a direction away from the chassis 10, so that the free end of the chassis 10 is supported on the road surface, thereby constructing a driving channel corresponding to the placement platform 11, and the auxiliary cleaning vehicle 200 can enter and exit the placement platform 11 through the driving channel; optionally, the angle between the reversible ladder 20 and the surface of the placement platform 11 can be 15°, 18°, 30°, 45° or 60°, etc.

[0054] Example 2

[0055] The reversible ladder 20 is telescopically connected to the chassis 10. The reversible ladder 20 is retracted onto the chassis 10 in the stored state, and extends relative to the chassis 10 in the deployed state to construct a driving passage that is inclined downward away from the chassis 10. This can improve the integration of the main cleaning vehicle 100 and avoid collision between the reversible ladder 20 and external structures.

[0056] When the auxiliary cleaning vehicle 200 is placed on the placement platform 11, the reversible ladder 20 can be switched to a stored state, at which time the reversible ladder 20 can be retracted onto the chassis 10 to avoid collision between the reversible ladder 20 and the external structure; when the auxiliary cleaning vehicle 200 needs to be lowered, the reversible ladder 20 can be switched to an unfolded state, that is, the reversible ladder 20 is extended relative to the chassis 10 and tilted downward in a direction away from the chassis 10, wherein the reversible ladder 20 has a connecting end connected to the chassis 10 and a free end. After the reversible ladder 20 is extended from the chassis 10, the free end can be supported on the road surface to construct a driving channel corresponding to the placement platform 11, so as to facilitate the auxiliary cleaning vehicle 200 to enter and exit the placement platform 11 through the driving channel.

[0057] Reference Figure 1 and Figure 5 In some embodiments of the present invention, the main cleaning vehicle 100 further includes a driving assembly 40, which is disposed on the chassis 10 and is transmission-connected to the flip ladder 20 to drive the flip ladder 20 to switch between the deployed state and the stored state, thereby realizing the storage and release of the auxiliary cleaning vehicle 200, and facilitating the auxiliary cleaning vehicle 200 to perform cleaning operations.

[0058] Specifically, the drive assembly 40 may include a power take-off and a hydraulic device. The power take-off can be connected to the chassis 10 of the main cleaning vehicle 100, and the power take-off can also be connected to the hydraulic device. In other words, the power of the chassis 10 can be transmitted to the hydraulic device through the power take-off, and the flip ladder 20 can be driven to switch between the deployed state and the stowed state through the hydraulic device; in combination with the aforementioned embodiment, the hydraulic device can drive the flip ladder 20 to rotate relative to the placement platform 11 to facilitate the storage and release of the auxiliary cleaning vehicle 200.

[0059] More specifically, the hydraulic device includes a hydraulic pump and an oil cylinder. The hydraulic pump is transmission-connected to the power take-off and the oil cylinder. That is, the power take-off drives the hydraulic pump, and the hydraulic pump drives the oil cylinder, thereby driving the tilting ladder 20 to rotate.

[0060] Reference Figure 1 and Figure 2 In some embodiments of the utility model, a locking device is provided on the chassis 10, and the locking device is configured to lock the auxiliary cleaning vehicle 200 on the placement platform 11; specifically, the auxiliary cleaning vehicle 200 is placed on the placement platform 11. In order to stably place the auxiliary cleaning vehicle 200 on the platform 11, a locking device can be provided on the chassis 10 of the main cleaning vehicle 100, and the auxiliary cleaning vehicle 200 is positioned on the placement platform 11 through the locking device; more specifically, when the auxiliary cleaning vehicle 200 returns to the placement platform 11 along the driving channel, the auxiliary cleaning vehicle 200 can cooperate with the locking device for positioning, and can automatically release the cooperation with the locking device when the auxiliary cleaning vehicle 200 is driving, so that the auxiliary cleaning vehicle 200 can be conveniently lowered to the road surface through the driving channel.

[0061] The auxiliary cleaning vehicle 200 has a walking assembly 241, which may include but is not limited to a crawler-type walking mechanism and a wheeled walking mechanism. The walking assembly 241 may cooperate with a locking device to achieve locking of the auxiliary cleaning vehicle 200. Regarding the cooperation between the locking device and the auxiliary cleaning vehicle 200, the utility model provides the following embodiments for better explanation:

[0062] Example 1

[0063] The locking device includes a plurality of positioning grooves, which are arranged on the surface of the placement platform 11 and are arranged at intervals along a predetermined direction, which is the driving direction of the auxiliary cleaning vehicle 200 on the placement platform 11; specifically, the auxiliary cleaning vehicle 200 moves through a plurality of running wheels and can return to the placement platform 11 along the driving channel constructed by the flip ladder 20. At the same time, in the driving direction of the auxiliary cleaning vehicle 200 returning to the placement platform 11, a plurality of positioning grooves are arranged at intervals on the placement platform 11, and the running wheels of the auxiliary cleaning vehicle 200 can be driven into the plurality of positioning grooves accordingly, and then the auxiliary cleaning vehicle 200 can stop moving. Since the plurality of running wheels of the auxiliary cleaning vehicle 200 have a large damping, the running wheels of the auxiliary cleaning vehicle 200 are difficult to rotate when not driven. Therefore, the plurality of positioning grooves can cooperate with the corresponding running wheels to position the auxiliary cleaning vehicle 200 on the placement platform 11. When the auxiliary cleaning vehicle 200 is lowered from the placement platform 11, the auxiliary cleaning vehicle 200 can travel so that the plurality of running wheels respectively walk out of the plurality of positioning grooves, thereby being lowered to the road surface through the driving channel.

[0064] Of course, a self-locking device may also be provided on the auxiliary cleaning vehicle 200. After the auxiliary cleaning vehicle 200 stops, the self-locking device may be activated to lock the running wheels, and the auxiliary cleaning vehicle 200 may be positioned through the cooperation of the plurality of positioning grooves and the corresponding running wheels, so that the auxiliary cleaning vehicle 200 may be stably placed on the placement platform 11. When the auxiliary cleaning vehicle 200 is lowered from the placement platform 11, the self-locking device of the auxiliary cleaning vehicle 200 may be released from the self-locking device, and the auxiliary cleaning vehicle 200 may be driven away from the placement platform 11, so that the plurality of running wheels may respectively move out of the plurality of positioning grooves, and thus be lowered to the road surface through the driving channel.

[0065] Example 2

[0066] Reference Figure 1 and Figure 2The locking device includes a plurality of positioning teeth 12, which are arranged on the surface of the placement platform 11 and are arranged at intervals along a predetermined direction, which is the driving direction of the auxiliary cleaning vehicle 200 on the placement platform 11; specifically, the auxiliary cleaning vehicle 200 moves through the walking track and can return to the placement platform 11 along the driving channel constructed by the flip ladder 20. At the same time, in the driving direction of the auxiliary cleaning vehicle 200 returning to the placement platform 11, a plurality of positioning scales are arranged at intervals on the placement platform 11, and the walking track of the auxiliary cleaning vehicle 200 can correspondingly travel to the top of the positioning teeth 12 and engage with the positioning teeth 12, and then the auxiliary cleaning vehicle 200 can stop moving, and because the walking rate of the auxiliary cleaning vehicle 200 has a large damping, the walking track of the auxiliary cleaning vehicle 200 is difficult to move when not driven. Therefore, the plurality of positioning teeth 12 can cooperate with the walking track to position the auxiliary cleaning vehicle 200 on the placement platform 11. When the auxiliary cleaning vehicle 200 is lowered from the placement platform 11 , the auxiliary cleaning vehicle 200 can travel so that the walking track leaves from above the plurality of positioning teeth 12 , and is lowered to the road surface through the driving passage.

[0067] Of course, a self-locking device may also be provided on the auxiliary cleaning vehicle 200. After the auxiliary cleaning vehicle 200 stops, the self-locking device is activated to lock the walking track, and the auxiliary cleaning vehicle 200 is positioned through the cooperation between the plurality of positioning teeth 12 and the walking track, so that the auxiliary cleaning vehicle 200 can be stably placed on the placement platform 11. When the auxiliary cleaning vehicle 200 is lowered from the placement platform 11, the self-locking device of the auxiliary cleaning vehicle 200 can be released from the self-locking device and drive away from the placement platform 11, so that the walking track leaves from above the plurality of positioning teeth 12, and is then lowered to the road surface through the driving channel.

[0068] Reference Figure 4 In some embodiments of the present invention, the main cleaning vehicle 100 further includes a water system 50, which is connected to the water tank 30. One end of the water system 50 is connected to the water tank 30, and the other end is provided with a joint, which is configured to connect to the auxiliary cleaning vehicle 200 to replenish the cleaning liquid for the auxiliary cleaning vehicle 200, thereby facilitating the cleaning operation of the auxiliary cleaning vehicle 200.

[0069] Specifically, the water system 50 may include a water pump and a pipeline. The water pump is arranged on the chassis 10 of the main cleaning vehicle 100, and is used to drive the cleaning liquid in the water tank 30 to flow to the auxiliary cleaning vehicle 200. One end of the pipeline is connected to the water tank 30, and the other end of the pipeline is provided with a joint. The joint can enable the pipeline to be quickly connected to the auxiliary cleaning vehicle 200, which is convenient for replenishing the cleaning liquid of the auxiliary cleaning vehicle 200 and improving the working efficiency.

[0070] Reference Figures 1 to 5 According to the cleaning system 1000 in the embodiment of the present utility model, the cleaning system 1000 includes the main cleaning vehicle 100 in the above embodiment and the auxiliary cleaning vehicle 200 in the above embodiment.

[0071] Among them, the auxiliary cleaning vehicle 200 is arranged on the placement platform 11, and the auxiliary cleaning vehicle 200 includes a body 240 and a cleaning component 220. The body 240 is suitable for entering or leaving the placement platform 11 along the driving channel. The cleaning component 220 is used to clean the working surface. By applying the aforementioned main cleaning vehicle 100, the main cleaning vehicle 100 cooperates with the auxiliary cleaning vehicle 200, and the main cleaning vehicle 100 is used to transport the auxiliary cleaning vehicle 200 on the road. The auxiliary cleaning vehicle 200 can be used for cleaning in areas such as subway entrances and urban underground passages, thereby improving the operating efficiency of the cleaning system 1000 and reducing labor intensity.

[0072] Specifically, in the main cleaning vehicle 100, a placement platform 11 is provided on the chassis 10, and a reversible ladder 20 rotatably connected to the chassis 10 is provided.

When the positioning member 247 is in the first position, the bottom of the positioning member 247 is not lower than the top of the walking module 222. At this time, the main body 242 of the machine body 240 is in an unlocked state, and the walking module 222 can move freely. When the positioning member 247 is in the second position, the bottom of the positioning member is lower than the top of the walking module 222. At this time, the main body 242 of the machine body 240 is in a locked state, and the walking module 222 cannot move freely, thereby fixing the position of the machine body 240. By driving the positioning member 247 to move between the first and second positions by the third driving member 246, the unlocking and locking states of the machine body 240 can be switched, and the position of the machine body 240 can be fixed or allowed to move freely as needed.

[0102] In some embodiments of the present invention, the boom assembly 210 includes a boom 211, a hoisting drive mechanism 214, a pulley group 215, and a rope group 216. The boom 211 can be extended or retracted in the front and rear directions as needed. The boom 211 is controlled to be extended and retracted by the rope group 216. The hoisting drive mechanism 214 is driven by a motor to provide power for the extension and retraction of the boom 211.

The pulley block 215 includes a first pulley 215a, a second pulley 215b, a third pulley 215c and a fourth pulley 215d, and the rope block 216 includes a first rope 216a, a second rope 216b and a third rope 216c. The first arm 213a is configured to be a cantilever with a fixed end connected to the body 240, the first pulley 215a is connected to the fixed end of the first arm 213a, the second pulley 215b is connected to the free end of the first arm 213a, the third pulley 215c is connected to the second arm 213b and is close to the free end, the fourth pulley 215d is connected to the second arm 213b and is close to the fixed end, one end of the first rope 216a is connected to the second arm 213b, and the other end passes through the first pulley 215a and the second pulley 215b to connect the second arm 213 b and is close to the fixed end, one end of the second rope 216b is connected to the second pulley 215b and is suitable for being wound around the second pulley 215b, and the other end passes around the third pulley 215c to be connected to the third section arm 213c and is close to the fixed end of the third telescopic arm, one end of the third rope 216c is connected to the second section arm 213b and is close to the free end, and the other end passes around the fourth pulley 215d to be connected to the third section arm 213c, the winch drive mechanism 214 is connected to the first section arm 213a, and is drivingly connected to the first rope 216a, for driving the boom 211 to extend and retract. When the boom 211 needs to be retracted, the winch drive mechanism 214 starts to rotate in the first direction under the drive of the motor, and a friction force is generated between the first rope 216a and the winch drive mechanism 214, and the first rope 216a is driven to move under the action of the friction force. One end of the first rope 216a passes around the first pulley 215a and the second pulley 215b, and the movement of the first rope 216a drives the first pulley 215a and the second pulley 215b to move. The second pulley 215b includes two symmetrically arranged pulleys, and a connecting shaft is provided between the two pulleys. The movement of the second pulley 215b drives the first rope 216a to wind around the second pulley 215b, thereby generating a pulling force on the other end of the first rope 216a. The other end of the first rope 216a is connected to the fixed end of the second arm 213b. The fixed end of the second arm 213b retracts toward the fixed end of the first arm 213a under the action of the pulling force of the first rope 216a. One end of the second rope 216b is fixed on the connecting shaft of the second pulley 215b. When the second pulley 215b rotates, the second rope 216b can be wound around the connecting shaft of the second pulley 215b. The overall length of the second rope 216b is shortened and a certain pulling force is generated on the third pulley 215c connected to the free end of the second arm 213b, thereby driving the free end of the second arm 213b to shrink toward the fixed end of the first arm 213a.The second arm 213b contracts toward the fixed end of the first arm 213a, and the fourth pulley 215d provided at the fixed end of the second arm 213b also moves toward the fixed end of the first arm 213a, generating a certain pulling force on the third rope 216c wound around the fourth pulley 215d, thereby driving the third arm 213c connected to the other end of the third rope 216c to also move toward the fixed end of the first arm 213a. The second arm 213b and the third arm 213c both move toward the fixed end of the first arm 213a, and the arm frame 211 gradually completes the contraction. On the contrary, when the boom 211 needs to be extended, the winch drive mechanism 214 starts to rotate in the second direction driven by the motor, and the second direction is opposite to the first direction. The second pulley 215b releases the first rope 216a wound on the symmetrical pulleys at both ends and the second rope 216b wound on the connecting shaft, and the second section arm 213b and the third section arm 213c move toward the fixed end away from the first section arm 213a, and the boom 211 gradually completes the extension.

At least two rollers 2256 are provided, that is, two rollers 2256, four rollers 2256, five rollers 2256 or even more. Each roller 2256 provides support at a different position. By arranging at least two rollers 2256 at intervals, the contact cleaning module 225 can maintain balance on the working surface and evenly distribute weight, prevent the module from tilting or losing balance, and ensure the stability and consistency of the cleaning process. In addition, the interval arrangement between the rollers 2256 can enable the contact cleaning module 225 to better adapt to the curved surface or protrusion on the working surface when contacting the working surface and moving, thereby ensuring the coverage and cleaning of the entire working surface.

[0110] In some embodiments, the contact cleaning module 225 further includes a baffle 2257 and a spray rod 2258. The baffle 2257 is connected to the first connecting frame 2251, and the baffle 2257 extends in the direction of the central axis of rotation of the sweeping brush group 2252 to shield the sweeping brush group 2252. The spray rod 2258 is connected to both ends of the baffle 2257 in the direction of travel of the cleaning assembly 220, and a nozzle 2259 is provided on the spray rod 2258, and the nozzle 2259 is used to spray the medium toward the sweeping brush group 2252. For details, please refer to Figures 10 to 15The baffle 2257 is connected to the first connecting frame 2251 and extends in the direction of the central axis of rotation around the sweeping brush group 2252. The overall structure is in an arch shape to block the sweeping brush group 2252, block the water mist and dust generated when the sweeping brush rotates, and prevent the splashing water or spilled objects generated during cleaning from splashing out of the sweeping brush group 2252 area, thereby improving the cleaning efficiency and reducing the impact on the surrounding environment. Among them, the baffle 2257 can be made of a PC transparent plate, which can provide a clear field of view and will not hinder the observation of the working area. At the same time, it has good wear resistance and is more scratch-resistant and impact-resistant than ordinary plastic plates, so that the baffle 2257 is not easily scratched or damaged during use, and can maintain good transparency and appearance. The spray rod 2258 is connected to the two ends of the baffle 2257 in the direction of travel of the cleaning assembly 220, that is, at the front and rear ends of the baffle 2257. One or more nozzles 2259 can be provided on the spray rod 2258, and the nozzle 2259 sprays the medium toward the sweeping brush group 2252. The spray bars 2258 before and after the baffle 2257 can cover the entire range in the direction of travel of the cleaning assembly 220. The nozzles 2259 on the spray bars 2258 spray the medium to the sweeping brush group 2252, which can wet and dissolve the dirt or pollutants on the working surface, thereby achieving a more comprehensive and thorough cleaning effect. In addition, the spray bars 2258 on the baffle 2257 are located above the sweeping brush group 2252, and the nozzles 2259 spray appropriate media to wet and weight the dust particles, reduce their suspension in the air, and make them more easily settle to the ground, which can effectively reduce the concentration of dust in the air and help prevent the diffusion of dust particles, thereby controlling dust during the cleaning operation.

[0111] In some embodiments, the cleaning assembly 220 includes a non-contact cleaning module 226, which is detachably connected to the second mounting frame 224, and the non-contact cleaning module 226 is configured to spray a medium toward the work surface to clean the work surface. Figures 10 to 15 The cleaning assembly 220 may also include a non-contact cleaning module 226. The non-contact cleaning module 226 can avoid contact with the working surface. The cleaning medium is sprayed toward the working surface by using high-pressure gas or liquid to remove dirt and particles on the working surface, which is convenient for operation while avoiding the safety risks of contacting the working surface. By detachably connecting the non-contact cleaning module 226 to the second mounting frame 224, the non-contact cleaning module 226 can be more stably fixed on the cleaning body 221 and obtain sufficient support to ensure the stability and effect of the cleaning process. Among them, the non-contact cleaning module 226 may include a rotating nozzle 2261, which can rotate in a horizontal plane, and the nozzle 2259 of the rotating nozzle 2261 can automatically adjust the angle up and down.

[0112] In some embodiments, the cleaning assembly 220 further includes a wiper module 227, which is connected to the cleaning body 221 and can rotate between a storage position and a working position. The wiper module 227 is stored on the cleaning body 221 in the storage position, and can extend out of the cleaning body 221 in the working position to scrape water off the working surface. Figures 10 to 15 The wiper module 227 is used to scrape off water stains on the working surface, reduce the impact of water stains on the working surface, and avoid water accumulation. The wiper module 227 is connected to the cleaning body 221 and has a storage state and a working state. The wiper module 227 can be switched between the storage state and the working state to ensure that the wiper module 227 can provide an effective wiping function when needed, and does not interfere with the operation of the cleaning component 220 when not needed. When the wiper module 227 is in the storage state, the wiper module 227 is in the storage position and is stored on the cleaning body 221, and will not interfere with the working surface, so as to avoid the wiper module 227 affecting the cleaning operation of the working surface. When the wiper module 227 is in the working state, the wiper module 227 can extend from the cleaning body 221 to the working position, so that the wiper module 227 is close to the working surface and scrapes off water stains on the working surface. The wiper module 227 can control the storage and extension of the wiper module 227 manually or automatically, and this process can be achieved by a manual button, switch or sensor.

[0113] In some embodiments, in the direction of travel of the cleaning assembly 220, the wiper module 227 is disposed at the rear side of the cleaning body 221. Figures 10 to 15 The wiper module 227 is arranged at the rear side of the cleaning body 221, and the wiper module 227 faces backward relative to the moving direction of the cleaning body 221. When the cleaning assembly 220 moves forward, the wiper module 227 can extend backward to timely scrape off the water remaining on the working surface after the cleaning operation, avoid stagnant water or water stains flowing to the cleaned area, and keep the entire working area clean. In the working state of the wiper module 227, it can be autonomously controlled according to the moving direction and speed of the cleaning assembly 220 to ensure that the water on the working surface is scraped off in time.

[0114] In some embodiments, the wiper module 227 includes a second connecting frame and a wiper plate 2272. One end of the second connecting frame is connected to the cleaning body 221 and can be turned upside down. The second connecting frame has multiple positioning positions.

For details, please refer to Figures 10 to 15, one end of the second connecting frame is connected to the cleaning body 221, and the other end is connected to the wiper 2272, so that the wiper 2272 is tightly combined with the cleaning body 221. At the same time, the second connecting frame can be flipped in the up and down direction and has multiple positioning positions. The angles of the second connecting member 2271 relative to the working surface are different in the multiple positioning positions. For example, one of the cleaning body 221 and the second connecting frame includes multiple first positioning parts, and the other includes a second positioning part. The second positioning part can selectively cooperate with one of the multiple first positioning parts to position the second connecting frame, and the multiple first positioning parts and the second positioning parts cooperate to adjust the angle of the second connecting frame. The second connecting frame can be locked at multiple positioning positions, so that the wiper 2272 can have different angles and heights relative to the working surface to meet the needs of different working surfaces. In addition, the angle of the wiper 2272 relative to the working surface can be flexibly adjusted by the second connecting frame. Different working surfaces may require different angles for wiping. By switching different positioning positions, the wiper 2272 can contact the working surface at multiple angles to ensure efficient scraping of water. In addition, the wiper blade 2272 can be a long rubber plate, which is fixed to the second connecting frame by bolts. The long rubber plate is soft and durable, and can fit the work surface tightly, ensuring that water stains and residues on the work surface are effectively removed. By bolting, the wiper blade 2272 can be firmly connected to the second connecting frame to avoid movement or bending during the wiping process. In addition, bolting also makes it more convenient to replace the wiper blade 2272.
