[0057] In addition, the recovery mechanism according to an embodiment of the present application also has the following additional technical features:

[0058] As shown in Figures 3-5 , the recovery tank 21 is convexly arranged, and the lower half of the recovery tank 21 is communicated with the connecting pipe 211. This design can make the dirt adsorbed from the gap between the top ends of the outer suction tank 22 and the inner suction tank 23 be filtered by the filter plate 214, so that the dirt adsorbed at the connecting pipe 211 contains less impurities.

[0064] Thus, the inner suction tank 23 and the outer suction tank 22 can be installed and disassembled through the threaded connection between the bolt 233 and the nut seat 223.

[0065] Further, as shown in Figure 1 and Figure 2 and Figure 6 andFigure 7 As shown in the second aspect, according to the landmark cleaning device, the recycling mechanism further comprises a trolley 1, the trolley 1 comprises a storage box 11, a fixing frame 12, a workbench 13, a high-pressure air blower 14 and a water tank 15, the fixing frame 12 is fixedly connected to the storage box 11, the workbench 13 is connected to the fixing frame 12 in a liftable manner, the high-pressure air blower 14 is fixedly connected to the fixing frame 12, an air inlet end of the high-pressure air blower 14 is communicated with the recycling cabin 21 to provide suction to the recycling cabin 21, and an air outlet end of the high-pressure air blower 14 is communicated with the storage box 11 to store the sucked sewage in the storage box 11, and the water tank 15 is fixedly connected to the storage box 11.

[0066] The cleaning assembly 3 comprises a high-pressure water pump 31 fixedly connected to the workbench 13, a water inlet end of the high-pressure water pump 31 is communicated with the water tank 15, and a water outlet end of the high-pressure water pump 31 is communicated with a shunt cabin 32, so that the water source in the water tank 15 is delivered into the shunt cabin 32 by the high-pressure water pump 31, the shunt cabin 32 is coaxially inserted and matched with the recycling assembly 2, the shunt cabin 32 is communicated with a high-pressure spray head 322, and then the water source is sprayed to the landmark on the ground by the high-pressure spray head 322 to wash the landmark.

[0067] It should be noted that the fixing ring 212 can be fixedly connected to the lower end face of the workbench 13 by screws.

[0068] Further, the storage box 11 is provided with a drain port 111, so that the sewage stored in the storage box 11 can be discharged, and the sewage can be treated and reused by subsequent purification equipment and other prior art means.

[0069] Further, as shown in the second aspect, Figure 2 Further, the workbench 13 is hingedly connected with telescopic pieces 131, the telescopic pieces 131 are hingedly connected to the fixing frame 12, so that the height of the workbench 13 can be changed by the telescopic change of the telescopic pieces 131.

[0072] Further, the limiting rod 133 is sleeved with a first spring 134, and the two ends of the first spring 134 abut against the fixing frame 12 and the workbench 13, respectively.

[0073] Therefore, when the telescopic part 131 is telescoped, the workbench 13 can only change in height through the interaction between the limiting rod 133 and the limiting frame 132, and the first spring 134 is designed to enable the workbench 13 to continuously abut against the ground with elastic force.

[0074] Further, as shown in Figure 7 the top end of the shunt cabin 32 is communicated with a throat pipe 321, and the throat pipe 321 is communicated with the water outlet end of the high-pressure water pump 31 and the recovery assembly 2.

[0075] The use process of the recovery mechanism according to the embodiments of the present application will be described below with reference to the accompanying drawings:

[0076] In specific use, the water source in the water tank 15 is delivered to the shunt cabin 32 through the high-pressure water pump 31, and is sprayed to the landmark through the high-pressure spray head 322 at the bottom side of the shunt cabin 32 to perform high-pressure flushing on the bottom edge, and the impact force of the water flow is used to clean the dirt on the landmark, and at the same time, the suction provided by the high-pressure air blower 14 to the outer suction cabin 22 and the inner suction cabin 23 is used to generate suction at the interval between the bottom sides of the outer suction cabin 22 and the inner suction cabin 23 around the shunt cabin 32, so that the cleaned sewage and sundries on the landmark are sucked, and the sucked sewage and sundries flow into the recovery cabin 21 from the interval between the top ends of the outer suction cabin 22 and the inner suction cabin 23, are filtered through the filter plate 214, and then the sewage is delivered to the storage box 11 through the high-pressure air blower 14, and the sundries are retained on the filter plate 214, and finally, the sundries on the filter plate 214 can be cleaned by dismounting the recovery cabin 21 from the workbench 13 and dismounting the cabin cover 213 from the recovery cabin 21.

[0077] In the related art, the number of high-pressure spray heads 322 on the shunt cabin 32 is limited, and there is an interval between the high-pressure spray heads 322, and there is also an interval between the water flows sprayed by the high-pressure spray heads 322, so that the cleaning of the landmark is affected by the interval between the high-pressure water flows, and the landmark cannot be completely cleaned, and at the same time, only the high-pressure water flow is used to flush the landmark, which can cause some marks generated by tire friction to be not cleaned, thereby affecting the reflection ability of the landmark.

[0078] According to some embodiments of the present application, as shown in Figures 6-8 the high-pressure spray heads 322 are uniformly arranged at the bottom side of the shunt cabin 32, and the high-pressure spray heads 322 are arranged in the same direction and at the same angle, so that the high-pressure water flow sprayed by the high-pressure spray heads 322 generates a reaction force on the shunt cabin 32, and the shunt cabin 32 has rotational kinetic energy.

[0079] As shown in Figure 7As shown, the throat pipe 321 is fixed with a limiting ring 323, and the throat pipe 321 is communicated with a rotary joint 324, which is communicated with the water outlet of the high-pressure water pump 31.

[0080] Wherein, the limiting ring 323 and the recess on the hatch cover 213 are movably connected.

[0081] Therefore, under the rotation energy provided by the high-pressure water flow sprayed by the high-pressure nozzle 322, the shunt cabin 32 will rotate on the hatch cover 213, and then the water flow sprayed by the high-pressure nozzle 322 will fully contact the landmark without dead angle, thereby improving the washing ability of the landmark.

[0082] Further, the upper end surface of the shunt cabin 32 is uniformly provided with a protrusion 325, which is connected with the recess 232, thereby driving the inner sump cabin 23 to rotate when the shunt cabin 32 rotates, and the outer sump cabin 22 will also rotate synchronously because it is fixed with the inner sump cabin 23.

[0083] Further, the lower end surface of the shunt cabin 32 is uniformly provided with a connecting plate 33, which is detachably fixed to the shunt cabin 32, and the connecting plate 33 is provided with a polishing strip 331, which is made of soft and wear-resistant material.

[0084] Therefore, it can be understood that when the high-pressure nozzle 322 sprays high-pressure water flow, the shunt cabin 32 will be driven to rotate under the action of the high-pressure water flow, thereby driving the inner sump cabin 23, the outer sump cabin 22 and the polishing strip 331 installed at the bottom end of the shunt cabin 32 to rotate synchronously. It can be understood that the shunt cabin 32 during rotation will make the high-pressure water flow sprayed by the high-pressure nozzle 322 on the shunt cabin 32 to wash the landmark without dead angle, and the polishing strip 331 rotating at the same time can polish the landmark during washing, thereby further improving the cleaning effect of the landmark.

[0085] In the related art, when the landmark is washed by high-pressure water flow, the high-pressure water flow will splash to the ground, and if the splashed sewage is not treated, the water recovery rate will be reduced, and the ground environment around the landmark will be affected.

[0086] According to some embodiments of the present application, as shown in Figures 9-10 As shown, the outer sump cabin 22 is provided with a dust removal assembly 4, which includes a lifting ring 41, a vertical rod 42 and a clamping ring 43. The lifting ring 41 is slidingly inserted into the annular cabin 222, the vertical rod 42 is fixed to the lifting ring 41, the vertical rod 42 is slidingly inserted into the annular cabin 222, and the clamping ring 43 is detachably fixed to one end of the lifting ring 41 extending out of the annular cabin 222.

[0087] Specifically, the radial section of the lifting ring 41 is T-shaped, and the lifting ring 41 and the annular cabin 222 are limited to slide together, avoiding the lifting ring 41 from separating from the annular cabin 222.

[0088] Further, the part of the vertical rod 42 between the lifting ring 41 and the annular cabin 222 is sleeved with the second spring 421, so that the lifting ring 41 has elastic potential energy downward in the annular cabin 222.

[0089] Further, the radial section of the clamping ring 43 is Y-shaped, and the clamping ring 43 is clamped to the lifting ring 41, and specifically can be fixed by screws and the like, and the side of the clamping ring 43 away from the lifting ring 41 is provided with a brush 431.

[0090] Therefore, when the landmark is high-pressure washed, the shunt cabin 32 rotates under the action of the high-pressure water flow, and at the same time drives the outer dirt suction cabin 22 to rotate, and the lifting ring 41 rotates synchronously with the outer dirt suction cabin 22 through the insertion of the vertical rod 42 and the annular cabin 222, and then the brush 431 at the bottom end of the lifting ring 41 rotates, and the rotating brush 431 can clean the debris on the landmark to a certain extent before cleaning, avoiding that too many debris are sucked back into the recycling cabin 21, and at the same time, the elastic action of the second spring 421 will make the lifting ring 41 drive the brush 431 to keep abutting against the ground, avoiding that a large gap appears between the brush 431 and the landmark due to the ups and downs of the terrain, and the existence of the brush 431, the clamping ring 43 and the lifting ring 41 will block the splashing of sewage during the washing process, avoiding that the sewage splashes outside the outer dirt suction cabin 22, and the sewage is as much as possible gathered inside the outer dirt suction cabin 22, and then the spacing between the outer dirt suction cabin 22 and the inner dirt suction cabin 23 is better for the adsorption of sewage, and at the same time, the influence on the surrounding environment during the cleaning process is avoided.

[0091] It should be noted that the specific model and specifications of the first spring 134, the high-pressure air blower 14, the high-pressure water pump 31, the high-pressure spray head 322 and the second spring 421 need to be determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the art, so it will not be described in detail.

[0092] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
