Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and more specifically, to an oil slick collection device for a waterborne sewage cleaning robot. Background Art

[0002] Currently, rivers, lakes, reservoirs and even the sea are often affected by subjective and objective factors, and there are various floating objects on the water surface. Moreover, the floating objects on the water surface are increasing year by year, posing a hidden danger to the safety of reservoirs, power stations, various water facilities and drinking water. Especially when the water area is polluted by oily sewage, the water resources are significantly reduced, the fish production drops sharply, and there is a large demand for sewage treatment. During the sewage treatment process, equipment for floating objects is needed to remove the floating oil in the sewage.

[0003] In the existing publicly disclosed technical literature, the patent with the Chinese patent publication number CN213867722U discloses an oil-water separation chamber for an oil slick collection robot. The adjacent chambers are connected through the bottom; it also includes a drain pipe, the drain pipe is connected to the bottom of any chamber on the tank body, and a water pump is provided on the drain pipe. This application is arranged on the oil slick collection robot, which separates the oil-water mixture collected by the oil collection mechanism while collecting it, facilitating the simplification of the subsequent collection object treatment process, and enabling the oil slick collection robot to have both the functions of collection and collection object treatment; however, this patent has the following defects.

[0004] During the sewage treatment process, an oil slick collection device for a waterborne sewage cleaning robot is needed to separate the oil from the water body, so as to collect the oil in the sewage. When treating sewage, since the oil in the sewage continuously enters, but when separating and sucking the oil, due to the relatively wide horizontal coverage area of the oil and the different vertical coverage thicknesses of the oil, it is difficult to perform lateral large-area displacement treatment on the oil on the sewage according to actual use needs, and it is difficult to synchronously perform vertical adaptive floating displacement treatment, resulting in low sewage treatment efficiency. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides the following technical solution: An oil slick collection device for a waterborne sewage cleaning robot, including a machine floating shell, a support frame and a linkage screw. The support frame is fixed at the top end of the inner wall of the machine floating shell, the linkage screw is rotatably connected to the inner wall of the support frame, and a sewage displacement two-way treatment mechanism is arranged on the outer wall of the linkage screw; the sewage displacement two-way treatment mechanism includes a threaded sleeve block threadedly connected to the outer wall of the linkage screw. The two ends of the linkage screw have opposite threads and are symmetrically provided. One side of the inner wall of the support frame is fixedly installed with a displacement motor, and a fixed connection is provided between the output end of the displacement motor and the linkage screw;

[0006] The lower surface of the threaded sleeve block is fixedly connected with a linkage block, and a guide groove plate is fixedly connected to the lower surface of the linkage block. Two sliding columns are slidably connected to the inner wall of the guide groove plate. A suction pipe is installed at the bottom end of the sliding column, and both sliding columns are fixedly connected to the suction pipe. A buoyancy plate is fixedly connected to the inner wall of the suction pipe, and a plurality of floating oil suction holes are formed on both sides of the buoyancy plate.

[0007] Preferably, both of the threaded sleeve blocks are slidably connected to the support frame. The outer wall of the threaded sleeve block and the inner wall of the support frame are both smooth surfaces. There is a gap between the two suction pipes, and the cross-sectional shape of the floating oil suction hole is circular. Both suction pipes are slidably connected to the machine floating shell, and a displacement distance sensor is fixedly installed on one side of the inner wall of the guide groove plate.

[0008] When the present technology is used for sewage treatment, the displacement motor drives the linkage screw to rotate forward. The linkage screw drives the two threaded sleeve blocks to move away from each other under the action of the threaded driving force. One threaded sleeve block moves forward, and the other threaded sleeve block moves backward. The linkage block drives the guide groove plate to move forward. The two sliding columns drive the same suction pipe to move forward. The suction pipe drives a plurality of floating oil suction holes to move forward, and the other suction pipe moves backward. At the same time, the buoyancy plate floats on the oil body on the upper surface of the sewage. As the thickness of the oil body changes continuously, the floating position of the buoyancy plate will also have a vertical displacement. The two suction pipes can realize vertical adaptive adjustment of displacement. Start the displacement motor to drive the linkage screw to rotate backward. The linkage screw drives the two threaded sleeve blocks to move closer to each other under the action of the threaded driving force. The distance between the two threaded sleeve blocks becomes smaller. The linkage block drives the guide groove plate to move backward. The guide groove plate makes the two sliding columns move backward. The sliding columns drive the suction pipe to move backward, and the other suction pipe moves forward. As the displacement motor continuously performs forward and reverse reciprocating drives, the two suction pipes can collect the grease in the sewage with a large horizontal displacement, and at the same time, the two suction pipes can collect the grease in the sewage with a vertical adaptive floating displacement.

[0009] Preferably, a hose is fixedly communicated with the upper surface of the suction pipe at a position far from the sliding column. The top end of the hose is fixedly communicated with a micro pump. A diversion pipe is fixedly communicated with the output end of the micro pump. A collection box is installed on the outer wall of the diversion pipe, and the collection box is fixedly connected to the machine floating shell. Both diversion pipes are fixedly communicated with the collection box. A valve is arranged on one side of the micro pump, and the valve is fixedly communicated with the machine floating shell.

[0010] When the present technology is used for sewage treatment, two micro pumps are started through a wireless controller. The hose causes the suction pipe to generate suction force. The suction pipe causes a plurality of floating oil suction holes to suck the grease on the upper surface of the sewage. Thus, the grease flows into the hose along the suction pipe and is poured into the collection box along the diversion pipe.

[0011] Preferably, a reinforcing frame is fixedly installed on one side of the machine floating shell, and a sewage diversion and expansion treatment component is arranged inside the reinforcing frame; the sewage diversion and expansion treatment component includes two micro electric cylinders fixedly arranged on the inner wall of the reinforcing frame, and the output end of each micro electric cylinder is fixedly connected with a sliding frame. The outer wall of the output end of the micro electric cylinder is slidably connected with the reinforcing frame. A support column is slidably connected to the inner wall of the sliding frame. The top and bottom of the sliding frame are both slidably connected with limiting rings, and both limiting rings are fixedly connected with the support column; the bottom of the support column is fixedly connected with an inclined oil guide plate, and an inclined guide plate is slidably connected to one side of the inclined oil guide plate. A guide rod is fixedly connected to the inner wall of the inclined guide plate, and a sliding sleeve block is slidably connected to the outer wall of the guide rod, and the sliding sleeve block is fixedly connected with the inclined oil guide plate;

[0012] A support plate is fixedly installed on one side of the inclined guide plate, and the support plate is fixedly connected with the machine floating shell. The two limiting rings are symmetrically arranged with respect to the sliding frame. The outer wall of the support column and the inner wall of the sliding frame are both smooth surfaces. The sliding sleeve block is slidably connected with the inclined guide plate, and the vertical cross-sectional shape of the guide rod is circular. A battery is fixedly installed on the lower surface of the reinforcing frame, and a wireless controller is fixedly connected to one side of the battery. Buoyancy platforms are fixedly connected to both sides of the machine floating shell, and a rotary motor is fixedly installed on the upper surface of the buoyancy platform; the output end of the rotary motor is fixedly connected with an impeller.

[0013] When the present technology is used for sewage treatment, the two micro electric cylinders respectively push the two sliding frames. One sliding frame moves forward and the other sliding frame moves backward. The sliding frame drives the support column to tilt forward. The inclined oil guide plate drives the sliding sleeve block to tilt forward. The sliding sleeve block tilts forward along the inner wall of the inclined guide plate. The inclined oil guide plate tilts forward on the inclined guide plate, and the other inclined oil guide plate tilts backward.

[0014] The technical effects and advantages of the present invention:

[0015] 1. Through the sewage displacement two-way treatment mechanism of the present invention, when the displacement motor drives the linkage screw to rotate forward, the distance between the two threaded sleeve blocks becomes larger. The suction pipe drives a plurality of floating oil suction holes to move forward, and the other suction pipe moves backward. The buoyancy plate floats on the oil body on the upper surface of the sewage. As the thickness of the oil body changes continuously, the floating position of the buoyancy plate will also undergo vertical displacement. By starting the displacement motor through the wireless controller to drive the linkage screw to rotate backward, the sliding column drives the suction pipe to move backward, and the other suction pipe moves forward. As the displacement motor continuously performs forward and reverse reciprocating drives, the two suction pipes can collect the grease in the sewage through large-area horizontal displacement, and the two suction pipes can collect the grease in the sewage through vertical adaptive floating displacement, simultaneously realizing large-area displacement treatment of the grease in the sewage in both horizontal and vertical directions, and greatly improving the sewage treatment efficiency.

[0016] 2. The present invention starts two micro-pump machines through a wireless controller. The micro-pump machines generate suction force on the hose, and the suction pipe enables multiple floating oil suction holes to suck the grease on the upper surface of the sewage. Thus, the grease enters the hose along the suction pipe and is poured into the collection box along the diversion pipe. In this way, the hose can move horizontally and variably along with the suction pipe, so as to continuously supply pressure to treat the sewage, and the sewage treatment efficiency is higher.

[0017] 3. Through the sewage diversion and expansion treatment component of the present invention, two micro-electric cylinders respectively push two sliding frames. One sliding frame moves forward and the other sliding frame moves backward. The support column drives the inclined oil guide plate to move forward obliquely. The inclined oil guide plate drives the sliding sleeve block to move forward obliquely. The sliding sleeve block moves forward obliquely along the inner wall of the inclined guide plate. The inclined oil guide plate moves forward obliquely on the inclined guide plate, and the other inclined oil guide plate moves backward obliquely. The two inclined oil guide plates can perform a diversion and expansion operation on the sewage, increasing the centralized diversion area of the grease in the sewage, and the efficiency of collecting the grease in the sewage is higher, and the sewage treatment efficiency is greatly improved.

[0033] In this embodiment, as shown in the attached Figure 7 - attached Figure 9 figure, a reinforcement frame 18 is fixedly installed on one side of the machine floating shell 1. A sewage diversion and expansion treatment component is arranged inside the reinforcement frame 18. The sewage diversion and expansion treatment component includes two micro electric cylinders 19 fixedly arranged on the inner wall of the reinforcement frame 18.

[0035] The working principle of the floating oil collection device of the water cleaning robot of the present invention is as follows:

[0036] First, when the present invention conducts sewage diversion expansion treatment and floating movement, the wireless controller 32 is powered by the battery 31. The wireless controller 32 starts two micro electric cylinders 19. The two micro electric cylinders 19 respectively push the two sliding frames 20. One sliding frame 20 moves forward and the other sliding frame 20 moves backward. The sliding frame 20 drives the support column 21 to tilt forward. At the same time, the support column 21 drives the two limiting rings 22 to slide along the rightward movement of the sliding frame 20, and the support column 21 drives the inclined oil guide plate 23 to tilt forward. The inclined oil guide plate 23 drives the sliding sleeve block 24 to tilt forward. The sliding sleeve block 24 tilts forward along the outer wall of the guide rod 25, and the sliding sleeve block 24 tilts forward along the inner wall of the inclined guide plate 26. In this way, the machine floating shell 1 supports the support plate 27, the support plate 27 supports the inclined guide plate 26, and the inclined oil guide plate 23 tilts forward on the inclined guide plate 26, and the other inclined oil guide plate 23 tilts backward. The two inclined oil guide plates 23 can conduct diversion expansion treatment on the sewage. The moving directions described in the above paragraph mainly refer to the view directions in Figure 7 - Attachment Figure 9 of the view.

[0037] Secondly, when the present invention performs floating movement collection, two rotary motors 29 are started through the wireless controller 32. The two rotary motors 29 respectively drive the two impellers 30 to rotate. The impellers 30 rotate on the sewage, so that the rotary motor 29 moves to the right. The rotary motor 29 drives the buoyancy platform 28 to float on the sewage and move to the right. Thus, the buoyancy platform 28 drives the machine housing 1 to move to the right. The machine housing 1 drives the two support plates 27 to move to the right synchronously. The support plate 27 drives the guide rod 25 to move to the right. The guide rod 25 drives the sliding sleeve block 24 to move to the right. The sliding sleeve block 24 makes the inclined oil guide plate 23 move to the right. The two inclined oil guide plates 23 move to the 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 flow along the two inclined guide plates 26 to gather on the inner wall of the machine housing 1. The moving directions described in the above paragraph mainly refer to the view directions in the attached Figure 7 - attached Figure 8 view directions.

[0038] Then, when the present invention performs pressurized suction, two micro pump machines 14 are started through the wireless controller 32. The micro pump machines 14 make the hose 13 generate suction force. The hose 13 makes the suction pipe 9 generate suction force. The suction pipe 9 sucks the grease on the upper surface of the sewage through the multiple floating oil suction holes 11. Thus, the grease enters the hose 13 along the suction pipe 9, enters the diversion pipe 15 through the hose 13, and is poured into the collection box 16 along the diversion pipe 15. In this way, the collection box 16 can separate and suck the grease in the sewage.

[0039] Finally, when the present invention performs two-way treatment of sewage displacement, the displacement motor 4 is started through the wireless controller 32. The displacement motor 4 drives the linkage screw 3 to rotate forward. The linkage screw 3 rotates forward inside the support frame 2. The linkage screw 3 drives the two threaded sleeve blocks 5 to move away from each other under the action of the threaded driving force. The distance between the two threaded sleeve blocks 5 becomes larger. One threaded sleeve block 5 moves forward, and the other threaded sleeve block 5 moves backward. The threaded sleeve block 5 drives the linkage block 6 to move forward. 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. The two sliding columns 8 drive the same suction pipe 9 to move forward. The suction pipe 9 drives the multiple floating oil suction holes 11 to move forward. 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 changes continuously, the floating position of the buoyancy plate 10 will also have a vertical displacement. Thus, the suction pipe 9 drives the sliding column 8 to slide vertically. The sliding column 8 drives the guide groove plate 7 to slide vertically. The two suction pipes 9 can realize vertical adaptive adjustment and displacement. The moving directions described in the above paragraph mainly refer to the view directions in the attached Figure 2 - attached Figure 6 view directions.

[0040] Distance sensing is performed on the front inner wall of the machine floating shell 1 through the displacement distance sensor 12. 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 through the wireless controller 32 to drive the linkage screw 3 to reverse. The linkage screw 3 drives the two threaded sleeve blocks 5 to approach each other under the action of the thread driving force. The distance between the two threaded sleeve blocks 5 becomes smaller, so that one threaded sleeve block 5 moves backward in displacement, and the other threaded sleeve block 5 moves forward in displacement. The threaded sleeve block 5 drives the linkage block 6 to move backward. The linkage block 6 drives the guide groove plate 7 to move backward. The guide groove plate 7 causes the two sliding columns 8 to move backward. The sliding columns 8 drive the suction pipe 9 to move backward, and the other suction pipe 9 moves forward. As the displacement motor 4 continuously performs forward and reverse reciprocating drives, the two suction pipes 9 can collect the grease in the sewage by lateral large-area displacement, and 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. Later, the entire machine floating shell 1 is taken out, the valve 17 is opened, and the grease collected inside the collection box 16 is discharged to the collection plastic bucket.
