[0002] At present, due to the influence of subjective and objective factors, the surface of rivers, lakes, reservoirs and even the sea often carries various floating objects, and the floating objects on the water surface are increasing year by year, posing hidden dangers to the safety of reservoirs, power stations, various water facilities and drinking water. Especially when the water area is polluted by oily sewage, water resources are significantly reduced, fish production is concentrated and decreased, and there is a large demand for sewage treatment. In the process of treating floating oil in sewage, it is necessary to use floating object equipment to remove the floating grease in sewage.

[0003] In the existing published technical documents, the Chinese patent announcement number CN213867722U discloses an oil-water separation cabin for an oil floating collection robot, in which adjacent chambers are connected through the bottom; it also includes a drain pipe, which is connected to the bottom of any chamber on the warehouse body, and a water pump is provided on the drain pipe. This application is set on the oil floating collection robot, and the oil and water are separated while collecting the oil-water mixture collected by the oil collection mechanism, which is convenient for simplifying the subsequent collection processing procedures, so that the oil floating collection robot has both the collection and collection processing functions; however, this patent has the following defects.

[0004] In the process of sewage treatment, an aquatic cleaning robot floating oil collection device is needed to separate grease from water, so as to collect grease in sewage. During sewage treatment, grease in sewage will continuously enter. However, when separating and absorbing grease, the grease covers a wide lateral area and the vertical coverage thickness of grease is also different. It is difficult to achieve large-scale lateral displacement treatment of grease on sewage according to actual use needs in fixed-position sewage grease separation, and it is difficult to simultaneously achieve vertical adaptive floating displacement treatment, resulting in low sewage treatment efficiency. Summary of the invention

[0032] The operating principle of the floating oil collection device of the water pollution cleaning robot of the present invention is as follows: First, when the present invention performs sewage diversion expansion treatment and floating movement, the wireless controller 32 is powered by the battery 31, and the wireless controller 32 starts two micro-electric cylinders 19. The two micro-electric cylinders 19 push the two sliding frames 20 respectively, one sliding frame 20 moves forward and the other sliding frame 20 moves backward, and the sliding frame 20 drives the pillar 21 to move forward obliquely, and at the same time, the pillar 21 drives the two limit rings 22 to slide along the right movement of the sliding frame 20, and the pillar 21 drives the inclined oil guide plate 23 to move forward obliquely, and the inclined oil guide plate 23 drives the sliding sleeve 24 to move forward obliquely, and the sliding sleeve 24 moves forward obliquely along the outer wall of the guide rod 25, and the sliding sleeve 24 moves forward obliquely along the inner wall of the inclined guide plate 26, so that the machine buoy 1 supports the support plate 27, and the support plate 27 supports the inclined guide plate 26, and the inclined oil guide plate 23 moves forward obliquely on the inclined guide plate 26, and the other inclined oil guide plate 23 moves backward obliquely, and the two inclined oil guide plates 23 can achieve diversion and expansion treatment of sewage. Please refer to the attached figure for the movement direction described in the above paragraph. Figure 7 -Attached Fig. 9 The view orientation.

[0033] Secondly, when the present invention performs floating mobile collection, two rotating motors 29 are started through the wireless controller 32. The two rotating motors 29 drive the two impellers 30 to rotate respectively. The impellers 30 rotate on the sewage, so that the rotating motor 29 moves right. The rotating motor 29 drives the buoyancy platform 28 to float on the sewage and move right, so that the buoyancy platform 28 drives the machine floating shell 1 to move right, and the machine floating shell 1 drives the two support plates 27 to move right synchronously. The support plates 27 drive the guide rods 25 to move right, and the guide rods 25 drive the sliding sleeve 24 to move right. The sliding sleeve 24 causes the inclined oil guide plate 23 to move right. The two inclined oil guide plates 23 move right synchronously. The two inclined oil guide plates 23 can realize large-area diversion of the floating oil on the upper surface of the sewage, divert it to the two inclined guide plates 26, and divert it along the two inclined guide plates 26 to the inner wall of the machine floating shell 1 for collection. Please refer to the attached for the movement direction described in the above paragraph. Figure 7 -Attached Figure 8 The view orientation.

[0034] Then, when the present invention performs pressurized suction, two micro pumps 14 are started through the wireless controller 32, the micro pump 14 causes the hose 13 to generate suction, the hose 13 causes the suction pipe 9 to generate suction, the suction pipe 9 causes the multiple floating oil suction holes 11 to suck the grease on the upper surface of the sewage, so that the grease enters the hose 13 along the suction pipe 9, enters the guide pipe 15 through the hose 13, and is poured into the collection box 16 along the guide pipe 15, so that the collection box 16 can separate and absorb the grease in the sewage.

[0035] Finally, when the present invention performs bidirectional sewage displacement treatment, the displacement motor 4 is started through the wireless controller 32, and the displacement motor 4 drives the linkage screw 3 to rotate forward, and the linkage screw 3 rotates forward inside the support frame 2. The linkage screw 3 drives the two threaded sleeves 5 to move away from each other under the action of the thread transmission force, and the distance between the two threaded sleeves 5 increases. The threaded sleeve 5 moves forward, and the other threaded sleeve 5 moves backward. The threaded sleeve 5 drives the linkage block 6 to move forward, and the linkage block 6 drives the guide groove plate 7 to move forward. The guide groove plate 7 makes the two sliding columns 8 move forward, and the two sliding columns 8 drive the same suction pipe 9 to move forward. The suction pipe 9 drives multiple floating oil suction holes 11 to move forward, and the other suction pipe 9 moves backward. At the same time, the buoyancy plate 10 floats on the oil body on the upper surface of the sewage. As the thickness of the oil body continues to change, the floating position of the buoyancy plate 10 will also be vertically displaced, so that the suction pipe 9 drives the sliding column 8 to slide vertically, and the sliding column 8 drives the guide groove plate 7 to slide vertically. The two suction pipes 9 can achieve vertical adaptive adjustment displacement. For the movement direction described in the above paragraph, please refer to the attached Figure 2 -Attached Figure 6 The view orientation.

[0036] The displacement distance sensor 12 senses the distance in front of the inner wall of the machine floating shell 1. When the distance value sensed by the displacement distance sensor 12 is the same as the three-centimeter distance value set by the wireless controller 32, the displacement motor 4 is started by the wireless controller 32 to drive the linkage screw 3 to reverse. The linkage screw 3 drives the two threaded sleeves 5 to approach each other under the action of the thread transmission force, and the distance between the two threaded sleeves 5 becomes smaller, so that the threaded sleeve 5 moves backward and the other threaded sleeve 5 moves forward. The threaded sleeve 5 drives the linkage block 6 to move backward. The linkage block 6 drives the guide groove plate 7 to move backward, and the guide groove plate 7 makes the two sliding columns 8 move backward, and the sliding column 8 drives the suction pipe 9 to move backward, and the other suction pipe 9 moves forward. As the displacement motor 4 continuously drives forward and backward reciprocatingly, the two suction pipes 9 can collect the grease in the sewage by horizontal displacement over a large area. At the same time, the two suction pipes 9 can collect the grease in the sewage by vertical adaptive floating displacement, and the sewage grease treatment efficiency is higher. At a later stage, the entire machine floating shell 1 is taken out, and the valve 17 is opened to discharge the grease collected in the collection box 16 into the collection plastic barrel.

In this technical solution, the electrical control components not mentioned are not shown in the figure because they belong to the prior art and will not be described here.
