[0028] In a preferred embodiment, the second nozzle 302 on the side of the cleaning nozzle 3 close to the cleaning brush 4 is longer than the first nozzle 301 on the other side. Figure 3 As shown, the second nozzle 302 is longer and is located on the cleaning brush 4. The second nozzle 302 is longer, so that it can be closer to the elevator surface, ensuring that the sprayed detergent can more accurately cover the area that the cleaning brush 4 is about to brush, and closely cooperate with the cleaning brush 4, so that the detergent can fully soak the stains before brushing, thereby enhancing the cleaning effect. At the same time, being set on the cleaning brush 4 further optimizes the coordination between the detergent spraying and the brushing action, thereby improving the cleaning efficiency.

[0029] The first nozzle 301 is mainly responsible for spraying water for cleaning, and plays a role in different stages of the cleaning process. Before cleaning begins, water is sprayed to initially wet the stains, or after cleaning is completed, water is sprayed to rinse off the residual detergent, so as to ensure the comprehensiveness and cleanliness of the cleaning work.

[0030] In the preferred embodiment, the nozzles of the first nozzle 301 and the second nozzle 302 are oriented toward the surface of the sightseeing elevator 1. The nozzles of the first nozzle 301 and the second nozzle 302 are oriented toward the surface of the sightseeing elevator 1, so that the sprayed water or detergent can directly act on the parts that need to be cleaned, thereby minimizing liquid splashing and waste, and improving the utilization rate of water resources and detergents. At the same time, the precise spraying direction ensures that the cleaning liquid can fully cover the outer surface of the elevator, effectively improving the cleaning effect, and ensuring that the entire outer surface of the elevator can be cleaned evenly and effectively.

[0031] In the preferred embodiment, the two movable seats 8 are respectively provided with a clean water tank 7 and a detergent tank 11, and the clean water tank 7 and the detergent tank 11 are connected to the cleaning nozzle 3 through a water pump. The clean water tank 7 is connected to the first nozzle 301 or the second nozzle 302 through a first pump body; The detergent water tank 11 is connected to the first nozzle 301 or the second nozzle 302 through the second pump body.

[0032] Separate clean water tanks and detergent tanks can store different cleaning media, avoid mixing different liquids, and ensure the purity and cleaning effect of the liquids used in the cleaning process. In different cleaning stages, it can accurately control whether to use clean water or detergent according to needs, which helps to achieve refined operation of the cleaning process.

[0033] Being respectively arranged on two moving seats 8 is conducive to dispersing the weight of the device, so that the force of the entire cleaning device on the moving track is more balanced, and the stability and safety of the cleaning rack 2 when moving are ensured.

[0034] The clean water tank 7 and the detergent tank 11 are connected to the cleaning nozzle 3 through a water pump, and the clean water tank 7 is connected to the first nozzle 301 or the second nozzle 302 through a first pump body, and the detergent tank 11 is connected to the first nozzle 301 or the second nozzle 302 through a second pump body. Such a connection mode can realize accurate flow control. By adjusting the power of the pump, the spraying amount of water or detergent can be adjusted according to actual needs, so as to realize flexible control of the cleaning strength and cleaning effect.

[0035] The use of pump bodies to achieve connectivity ensures efficient delivery of liquid from the water tank to the nozzle, ensures the continuity of the cleaning process, and avoids interruptions in cleaning or poor cleaning results due to insufficient liquid supply. At the same time, different pump bodies can provide independent delivery power for different cleaning liquids, making it easy to adjust the flow and pressure according to different cleaning needs, meet diverse cleaning tasks, and improve the adaptability and reliability of the entire cleaning device.

[0036] In the preferred embodiment, the mobile seat 8 includes an outer frame 801, a plurality of side wheels 804 are provided on both sides of the inner part of the outer frame 801, and an adjusting wheel 802 and a fixing wheel 803 are provided on the top of the outer frame 801; The cross section of the moving track 5 is an "I"-shaped structure: a plurality of side wheels 804 are arranged on both sides of the middle of the "I"-shaped structure and attached to the surface of the "I"-shaped structure; The adjusting wheel 802 and the fixing wheel 803 are attached to the top surface of the “I”-shaped structure.

[0037] The outer frame 801 serves as the main structure of the mobile seat 8, providing an installation foundation and support for components such as the side wheels 804, the adjusting wheels 802, the fixed wheels 803 and the water tank, thereby ensuring the relative positions of these components and the stability of their coordinated work.

[0038] It bears the weight of the entire cleaning device, provides a stable installation platform for the cleaning rack 2 and other components, and ensures the structural integrity of the entire cleaning device during movement and cleaning.

[0039] Side wheel 804: Multiple side wheels 804 are distributed on both sides of the middle of the "I"-shaped moving track 5, which increases the contact area between the moving base 8 and the moving track 5, improves the stability and carrying capacity of the moving base 8 when moving on the track, and can share the weight of the entire cleaning device, making the cleaning device move more smoothly in the horizontal direction.

[0040] The fitting mode of the side wheels 804 and the “I”-shaped structure limits the horizontal deviation of the moving base 8, ensuring that the cleaning rack 2 does not rock left and right when moving along the track, thereby improving the moving accuracy and safety of the cleaning device.

[0041] The adjusting wheel 802 and the fixed wheel 803 are fitted on the top surface of the "I"-shaped structure, and they cooperate with the side wheels 804 to stably position the moving seat 8 on the moving track 5 from the upper and lower directions, forming a stable support and guide system to prevent the cleaning device from jumping up and down or derailing during movement, thereby ensuring the stability of the cleaning device in the vertical direction.

[0042] During the operation of the moving seat 8, the adjusting wheel 802 can make certain position adjustments according to the slight unevenness or turning conditions of the track, further enhancing the adaptability and flexibility of the cleaning device moving on the moving track 5, and ensuring normal and stable operation under different working conditions.

[0043] In the preferred embodiment, both ends of the rotating shaft 809 of the adjusting wheel 802 are slidably connected to the sliding block 806, the sliding block 806 is slidably connected to the sliding groove 808, and a spring 807 is provided between the top of the sliding block 806 and the top of the sliding groove 808; When the moving seat 8 moves to the turning position of the moving track 5, the adjusting wheel 802 moves to enable the moving seat 8 to move at the turning position.

[0044] The sliding connection between the rotating shaft 809 and the sliding block 806, and the sliding connection between the sliding block 806 and the sliding groove 808, provide a flexible movement mechanism for the adjusting wheel 802. When the moving base 8 runs on the moving track 5, especially at a turning position, the structure allows the adjusting wheel 802 to adjust its position within a certain range according to the track shape and turning requirements.

[0045] The setting of spring 807 plays a role of buffering and resetting. In the normal straight state, spring 807 can keep the adjusting wheel 802 in a suitable position to ensure the stable operation of the moving seat 8; when the moving seat 8 reaches the turning position, the lateral force generated by the track on the adjusting wheel 802 will cause the sliding block 806 to slide in the sliding groove 808, and the spring 807 will be compressed or stretched, thereby adjusting the position of the adjusting wheel 802, so that the moving seat 8 can pass the turning smoothly, avoiding the phenomenon of jamming or derailment caused by rigid connection, and ensuring the smoothness and stability of the moving seat 8 when turning on the moving track 5.

[0046] The adjusting wheel 802 moves when the moving seat 8 moves to the turning position, which can effectively adapt to the curved shape of the moving track 5, and guide the moving seat 8 to move smoothly along the turning trajectory of the track, avoiding movement obstacles caused by the turning of the track, and improving the adaptability and reliability of the entire cleaning device, ensuring that the cleaning rack 2 can completely cover the surface of the sightseeing elevator 1 along the moving track 5 during the entire cleaning process, realizing a cleaning operation without dead angles.

[0047] In a preferred embodiment, a second driving motor 805 is further provided on one side of the outer frame 801 . A gear 10 is provided at the output end of the second driving motor 805 . The gear 10 meshes with a rack 9 on the moving track 5 .

[0048] The second driving motor 805 serves as a power source to provide the power required for the entire cleaning device to move, so that the cleaning rack 2 and its accessories can move on the moving track 5. The output power drives the gear 10 to rotate, driving the entire moving base 8 and the cleaning rack 2 to move along the track, realizing an automated cleaning process.

[0049] The meshing transmission mode of the gear 10 and the rack 9 can convert the rotational power output by the second drive motor 805 into the linear motion power of the cleaning device, and the transmission efficiency is high and stable. Compared with other transmission modes, this meshing structure can accurately transmit power, ensure the positioning accuracy of the cleaning device on the moving track 5, avoid slipping, ensure that the cleaning device moves accurately along the preset track, and realize accurate cleaning of the outer surface of the sightseeing elevator 1.

[0050] Example 2 Further illustrate with reference to Example 1, Figure 1-7 In the structure shown, S1, two movable rails 5 are installed on both sides of the sightseeing elevator 1 through multiple mounting brackets 6; installing the movable rails 5 through multiple mounting brackets 6 can ensure that the movable rails 5 are firmly installed on both sides of the sightseeing elevator 1, providing reliable support and guidance for the stable movement of the cleaning rack 2, and ensuring that the cleaning device will not affect the cleaning effect or cause safety hazards due to loose or unstable rails during subsequent operations.

[0051] S2. The cleaning rack 2 is installed on the moving track 5 through the moving seat 8. Clean water and detergent are respectively injected into the clean water tank 7 and the detergent tank 11. Corresponding liquids are injected into different water tanks to provide the required cleaning medium for subsequent different cleaning stages, which is convenient for accurate use according to the cleaning steps, and improves the cleaning efficiency and cleaning quality. At the same time, the cleaning rack 2 is installed on the track through the moving seat 8 to ensure that the cleaning rack 2 can run smoothly on the track, and prepare for subsequent mobile cleaning.

[0052] S3, the second driving motor 805 first drives the cleaning rack 2 to move from the bottom to the top of the sightseeing elevator 1, and the first nozzle 301 in front of the cleaning rack 2 sprays water on the surface of the sightseeing elevator 1. After reaching the top, the entire cleaning rack 2 starts to move downward, and the second nozzle 302 starts to spray detergent on the surface of the sightseeing elevator 1. At the same time, the cleaning brush 4 mixes the detergent to clean the surface of the sightseeing elevator 1; during the rising process from the bottom to the top, the first nozzle 301 first sprays water, which can wet the elevator surface, remove some dust and easily removable stains, and avoid direct use of detergents to cause waste. When the cleaning rack 2 reaches the top and starts to descend, the second nozzle 302 sprays detergent and the cleaning brush 4 cooperates to clean, which can make full use of gravity, so that the detergent can contact the stains more effectively during the downward flow process. The brushing of the cleaning brush 4 can enhance the ability to remove stubborn stains and improve the cleaning effect.

[0053] S4, after the cleaning rack 2 moves to the bottom of the sightseeing elevator 1, the first nozzle 301 sprays water on the surface of the sightseeing elevator 1 again to remove the detergent on the surface of the sightseeing elevator 1, and the cleaning rack 2 moves back and forth multiple times to rinse the surface of the sightseeing elevator 1; after the cleaning rack 2 returns to the bottom, the first nozzle 301 sprays water again to thoroughly rinse the detergent to prevent the detergent residue from damaging the surface of the sightseeing elevator 1 or affecting the appearance. The back and forth movement of the cleaning rack 2 for multiple rinses can further improve the rinse effect and ensure that the surface is clean and free of residue.

[0054] S5. After the cleaning is completed, the cleaning rack 2 moves to the bottom of the sightseeing elevator 1 to stay there and is set to be cleaned for 15-20 days.

[0055] After washing is completed, the cleaning rack 2 stops at the bottom, which does not affect the normal use of the sightseeing elevator 1 and is ready for the next cleaning. Setting a cleaning cycle of 15 to 20 days can reasonably arrange the cleaning frequency according to actual use, ensure that the outer surface of the sightseeing elevator 1 maintains good cleanliness, and avoid waste of resources or untimely cleaning due to too short or too long cleaning cycles.
