A cleaning mechanism is provided on the wastewater pool 1. The cleaning mechanism includes a collecting tank 3 and a pushing mechanism 4 for pushing floating objects on the water surface. The collecting tank 3 is arranged at one end of the wastewater pool 1, and the pushing mechanism 4 is arranged at the other end of the wastewater pool 1. A horizontal moving mechanism 5 is provided on one side of the wastewater pool 1 to drive the pushing mechanism 4 to move horizontally. A lifting mechanism 6 is installed on the horizontal moving mechanism 5 to drive the pushing mechanism 4 to move up and down. The pushing mechanism 4 includes a fixing plate 41, a baffle frame 42 and a driving baffle frame 43. The telescopic cylinder 44 of the frame 42 is flipped, the lower ends of the stop frame 42 are hinged with the cross bars 43 arranged on the lower ends of the fixed plate 41, the upper ends of the stop frame 42 are hinged with the telescopic ends of the telescopic cylinder 44, and the other end of the telescopic cylinder 44 is hinged with the middle of the fixed plate 41. The telescopic cylinder 44 can be a hydraulic cylinder or an electric telescopic cylinder 44; the outer side of the collection tank 3 is provided with a lifting plate 7, and the lifting plate 7 is connected with an oil-absorbing felt 8, which is connected by pasting or other pressing and fixing methods, and the collection tank 3 is provided with a driving mechanism 9 for controlling the lifting plate 7 to rise and fall.

When in use, the L-shaped rod body 31 on the collection tank 3 is clamped into the U-shaped slot 11.

[0022] like Figure 2 As shown, in this embodiment, the baffle frame 42 includes an oblique baffle 421, a mesh 422 and a side plate 423. The mesh 422 is horizontally arranged at the bottom end of the oblique baffle 421, and the side plates 423 are arranged on both sides of the oblique baffle 421. The oblique baffle 421 is conducive to moving the scum and oil stains on the surface of the wastewater, the oblique baffle 421 cooperates with the mesh 422 and the side plates 423 to facilitate the salvage of the scum, the side plates 423 can prevent the scum from sliding from the side, and the mesh 422 is conducive to the outflow of water.

[0023] like Figure 6 As shown, the driving mechanism 9 includes a first screw 91 and a first motor 92. Mounting seats 93 are provided at the upper and lower ends of the middle part of the collecting tank 3 near the baffle frame 42. The two ends of the first screw 91 are rotatably connected to the upper and lower mounting seats 93 respectively. The lifting plate 7 is threadedly connected to the first screw 91. The first motor 92 is connected to the upper end of the first screw 91. Both sides of the collecting tank 3 near the baffle frame 42 are provided with slide rails slidably connected to the first screw 91. The mechanism uses the first motor 92 to drive the first screw 91 to rotate, thereby driving the lifting plate 7 to move up and down, so that the height of the oil-absorbing felt 8 can be properly adjusted.

[0024] like Figure 1As shown in the figure, the horizontal moving mechanism 5 includes an installation groove 51, a second screw rod 52 and a second motor 53. The second screw rod 52 is rotatably connected to both ends of the installation groove 51, and one end thereof extends outwards and is connected to the second motor 53. A first moving seat 54 is threadedly connected to the second screw rod 52, and the first moving seat 54 is slidably connected to the side wall of the installation groove 51. This structure drives the second screw rod 52 to rotate through the second motor 53, thereby driving the first moving seat 54 to move horizontally, so as to drive the pushing mechanism 4 to move, so that floating substances such as horizontal scum and oil stains move towards the direction close to the oil-absorbing felt 8.

[0025] As Figure 3 As shown in the figure, the lifting mechanism 6 includes a U-shaped seat 61, a third screw rod 62 and a third motor 64. The U-shaped seat 61 is fixed on the first moving seat 54.

The second moving seat 63 is connected to the fixing plate 41 through a connecting rod 65.

[0026] In use, when there are too many floating substances on the water surface, the height of the lifting plate 7 is adjusted through the driving mechanism 9, so as to adjust the height of the oil-absorbing felt 8. The height of the retaining frame 42 is adjusted through the lifting mechanism 6, and the retaining frame 42 is driven by the horizontal moving mechanism 5 to move towards the direction of the oil-absorbing felt 8. During the process, the inclined baffle 421 of the retaining frame 42 is used to intercept the floating scum and oil stains on the water surface until the floating substances are pushed to move to a position close to the oil-absorbing felt 8. The oil-absorbing felt 8 is used to adsorb the oil stains, and then the retaining frame 42 is lifted to salvage the floating scum, and the water leaks out from the hole mesh 422 at the bottom of the retaining frame 42. Then the horizontal moving mechanism 5 drives the retaining frame 42 to continue to move forward above the collection tank 3. Subsequently, the telescopic cylinder 44 extends, so that the retaining frame 42 rotates around the hinge point at the lower part and turns over, so that the floating substances in the retaining frame 42 fall into the collection tank 3. The utility model can collect the floating substances on the water surface and adsorb and clean the oil stains on the water surface, and can effectively clean the floating substances such as floating scum and oil stains on the water surface, avoiding the blockage problem in subsequent treatment.
