Then start water pump 4 and deliver the water in the water storage box 3 to the water pipe 21, the water in the water pipe 21 is sprayed on the concrete slab through the water nozzle 22, thereby realizing the water spray maintenance work to the concrete slab; The nozzle 22 sprays the water that falls on the outside of the concrete slab and flows from the concrete slab, and then falls back to the water storage box 3 to be collected through the water leakage port 11, thereby realizing the recycling of water resources and reducing the waste of water resources; 22 During the water spraying process, start the second motor 52 and the second motor 52, the second motor 52 drives the second rotating shaft 521 and the connecting plate 53 to rotate, and then drives the concrete slab to rotate slowly, and the third motor 14 drives the third screw rod 15 Rotate, the third screw mandrel 15 drives the support frame 2 to slide along the second chute 13 during the rotation process, and through the cooperation of the second motor 52 and the third motor 14, the water nozzle 22 can spray water evenly on the outside of the concrete slab work to reduce the possibility of damage to concrete slabs due to uneven spraying of water;

The water that falls back into the water storage box 3 from the surface of the concrete slab will be filtered by the filter screen 61 before entering the water inlet pipe 41, so that the water ejected from the water nozzle 22 is difficult to contain more impurities and dirt, reducing the The impact of water quality on the maintenance work of concrete slabs; after the filter screen 61 has been used for a long time, dust and impurities are easy to adhere to the filter screen 61, and the first motor 33 is started to drive the first screw mandrel 34 to rotate, and the first screw mandrel 34 drives the fixed plate during the rotation process 341 and the cleaning brush 342 slide, so that the cleaning brush 342 cleans the filter screen 61, reducing the possibility that the mesh of the filter screen 61 is blocked by impurities and dirt; the first screw mandrel 34 drives the first bevel gear 312 to rotate during the rotation process, through Under the cooperation of the first bevel gear 312 and the second bevel gear 343 and the transmission of the first pulley 313, the second pulley 315 and the belt 316, the second screw mandrel 314 rotates, so that the scraper 7 is bonded to the storage tank. The dirt and impurities at the bottom of the water box 3 are cleaned, so that the impurities are discharged from the water storage box 3 through the discharge pipe 36, and the possibility of impurities and dirt affecting the water quality is reduced;

During the rotation of the first rotating shaft 311, it drives the cam 85 to squeeze the pressure plate 83 to slide down and squeeze the airbag 82. The gas inside the airbag 82 enters the cavity 71 through the U-shaped tube 86 and pushes the straight plate 72 to slide. The straight plate 72 drives the push rod 75 during the sliding process. Stretch out the first through hole 74, impel the larger impurities adhering to the scraper 7 to fall off, and facilitate the scraper 7 to clean the dirt and impurities better, and the sealing ring 742 provided in the sealing groove 741 makes the cavity 71 inside have a good The airtightness reduces the possibility that the water in the water storage box 3 enters the cavity 71 .

All of the above are preferred embodiments of the application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made according to the structure, shape, and principle of the application should be covered by the protection scope of the application. Inside.
