The device includes a base, a housing, a first oil pump, and a second oil pump fixedly mounted on the top of the base. The housing is located between the first and second oil pumps and has a first cavity and a second cavity. An oil suction pipe is fixedly connected to the suction end of the first oil pump, and a first oil delivery pipe is fixedly connected to the discharge end of the first oil pump. The end of the first oil delivery pipe away from the first oil pump extends into the second cavity. This utility model has a reasonable design and good practicality. It can effectively filter impurities in oil and automatically clean the filter screen surface, improving the filtration effect of the filter screen. Furthermore, it can effectively heat the oil, reducing its viscosity and improving its fluidity, thereby preventing clogging during oil transportation and improving oil transportation efficiency.

[0004] However, during the oil extraction process, underground oil often contains various impurities, such as silt, rock particles, and some solid or semi-solid petroleum polymers. When these impurities enter the oil pump through the pipeline, they can easily cause pipeline blockage and affect the normal operation of the oil pump. Utility Model Content

[0005] The purpose of this invention is to solve the problem that impurities in petroleum can clog oil pipes in existing petroleum pumping devices.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a self-cleaning and anti-clogging oil pumping device, including: a mounting base, and an oil pump A disposed on the upper surface of the mounting base. One end of the oil pump A is provided with an oil outlet pipe, and one end of the oil outlet pipe is connected to an external oil storage device via a flange. The other end of the oil pump A is provided with an oil inlet pipe, and one end of the oil inlet pipe is provided with a housing. One end of the housing is provided with an anti-clogging component for preventing the oil inlet pipe from being blocked. One end of the anti-clogging component is connected to the flange of the underground oil pumping pipe.

[0007] The anti-clogging assembly includes an inlet pipe A with a flange connected to the bottom of the sucker pipe, a cylinder welded to the bottom of the inlet pipe A, a cover plate with a flange connected to one end of the cylinder, and a sealing plate disposed on one side of the cover plate. The outer surface of the sealing plate is fitted and connected to the inner wall of the cylinder. A rotating shaft is disposed on one side of the sealing plate, and a blower wheel is rotatably connected to one end of the rotating shaft. The inlet pipe A is located above the blower wheel. A connecting rod is disposed at one end of the blower wheel. A cleaning brush is sleeved on the outer surface of the connecting rod. A filter screen is connected to the bottom end of the connecting rod through a bearing. One side of the cleaning brush is in contact with one side of the filter screen. The inlet pipe A is located on one side of the filter screen. The other end of the cylinder is flange-connected to the inlet pipe B.

[0008] Furthermore, a connecting pipe A is connected to one end of the inlet pipe B via a flange. One end of the connecting pipe A is connected to the box body. The box body contains a cavity A and a cavity B. One end of cavity A is connected to the connecting pipe B, and the connecting pipe A is connected to the interior of cavity A.

[0009] Furthermore, a filter plate is installed inside cavity B, and a diversion pipe A is installed inside cavity B. An oil pump B is installed at one end of diversion pipe A, and a diversion pipe B is installed at one end of oil pump B. One end of diversion pipe B is connected to the inside of the cylinder, and diversion pipe B is located between the blower wheel and the cleaning brush.

[0010] Furthermore, a controller is installed on the outer surface of the box, and flow sensors are installed inside both the inlet pipe A and the branch pipe A. Both sets of flow sensors are connected to the controller via signals.

[0014] Compared with existing technologies, the beneficial effects of this utility model include: The cylinder, inlet pipe A, windmill wheel, connecting rod, cleaning brush, and filter screen plate are as follows: When oil flows from the underground oil extraction pipe to the oil pump A, it first enters the inlet pipe A, which is located above the windmill wheel. Therefore, the impact force generated by the oil flow acts on the windmill wheel, driving it to rotate around its axis. This, in turn, drives the connecting rod to rotate synchronously, causing the cleaning brush, which is sleeved on the outer surface of the connecting rod, to rotate as well. Simultaneously, the oil flows through the windmill wheel to the filter screen plate for filtration, preventing impurities from causing blockages. Furthermore, because one side of the rotating cleaning brush contacts the filter screen plate, it can clean it, preventing blockages in the oil flow. Finally, the cover plate can be removed for replacement and cleaning, which not only improves the continuity and efficiency of oil extraction but also makes maintenance more convenient.

[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0022] According to one embodiment of the present invention, in conjunction with Figure 1 As shown.

[0023] A self-cleaning, anti-clogging oil pumping device includes: a mounting base 1, and an oil pump A2 disposed on the upper surface of the mounting base 1. One end of the oil pump A2 is provided with an oil outlet pipe 3, and one end of the oil outlet pipe 3 is flanged and connected to an external oil storage device. The other end of the oil pump A2 is provided with an oil inlet pipe 4, one end of the oil inlet pipe 4 is provided with a housing 5, and one end of the housing 5 is provided with an anti-clogging component 6 for preventing the oil inlet pipe 4 from being blocked. One end of the anti-clogging component 6 is flanged and connected to an underground oil pumping pipe 7.

[0024] In this embodiment, please refer to Figures 1-4The anti-clogging component 6 includes an inlet pipe A61 with a flange connected to the bottom end of the sucker pipe 7, a cylinder 62 welded to the bottom end of the inlet pipe A61, a cover plate 63 with a flange connected to one end of the cylinder 62, and a sealing plate 64 disposed on one side of the cover plate 63. The outer surface of the sealing plate 64 is fitted and connected to the inner wall of the cylinder 62. A rotating shaft is disposed on one side of the sealing plate 64, and a wind turbine 65 is rotatably connected to one end of the rotating shaft. The inlet pipe A61 is located above the wind turbine 65. A connecting rod 66 is disposed at one end of the wind turbine 65. A cleaning brush 67 is sleeved on the outer surface of the connecting rod 66. A filter screen plate 68 is connected to the bottom end of the connecting rod 66 through a bearing. One side of the cleaning brush 67 is in contact with one side of the filter screen plate 68. The inlet pipe A61 is located on one side of the filter screen plate 68. The other end of the cylinder 62 is flanged and connected to the inlet pipe B69. When oil flows from the underground sucker pipe 7 to the sucker pump A2, it first enters the inlet pipe A61. 61. The inlet pipe A61 is located above the wind turbine 65. Therefore, when oil enters the cylinder 62, the impact force generated by the oil flow will act on the wind turbine 65, thereby driving the wind turbine 65 to rotate around the shaft. The rotation of the wind turbine 65 drives the connected connecting rod 66 to rotate synchronously. Therefore, the cleaning brush 67 sleeved on the outer surface of the connecting rod 66 also rotates. At the same time, after passing through the wind turbine 65, the oil flows to the filter screen plate 68. The filter screen plate 68 filters the oil, intercepting impurities and preventing impurities from entering the subsequent oil pump A2 and causing blockage. This causes one side of the rotating cleaning brush 67 to contact the filter screen plate 68, thereby cleaning the filter screen plate 68 and brushing off the impurities intercepted on the filter screen plate 68 to prevent blockage of the oil flow. Then, the cover plate 63 is removed to replace and clean the anti-clogging components. This not only greatly improves the continuity and efficiency of oil pumping operations, but also makes maintenance more convenient.

[0025] One end of the inlet pipe B69 is flanged and connected to the connecting pipe A81. One end of the connecting pipe A81 is connected to the housing 5. The housing 5 is provided with a cavity A51 and a cavity B52. One end of the cavity A51 is provided with the connecting pipe B82, and the connecting pipe A81 is connected to the inside of the cavity A51. The filtered oil enters the housing 5 sequentially from the inlet pipe B69 and the connecting pipe A81. Then, the oil in the cavity A51 is pumped by the oil pump A2 and enters the external oil storage device through the connecting pipe B82 and the oil outlet pipe 3.

[0026] The cavity B52 is equipped with a filter plate 83 and a diversion pipe A84. One end of the diversion pipe A84 is equipped with an oil pump B85, and the other end of the oil pump B85 is equipped with a diversion pipe B86. One end of the diversion pipe B86 is connected to the inside of the cylinder 62. The diversion pipe B86 is located between the blower wheel 65 and the cleaning brush 67. When the filter screen plate 68 in the cylinder 62 is overloaded, the oil inside can be pumped into the cavity B52 through the oil pump B85, and then filtered by the filter plate 83, so that it merges with the oil in the cavity A51.

[0027] A controller 9 is installed on the outer surface of the housing 5. Flow sensors 91 are installed inside the inlet pipe A61 and the branch pipe A84. Both sets of flow sensors 91 are connected to the controller 9. The flow sensors 91 in the inlet pipe A61 and the branch pipe A84 detect the flow rate of oil in the corresponding pipes and transmit the signal to the controller 9 to provide data reference for whether a blockage occurs during operation.

[0028] The inside of the diversion pipe B86 is equipped with a solenoid valve 92, which is connected to the controller 9. The controller 9 controls the opening and closing of the solenoid valve 92 in the diversion pipe B86 according to the signal of the flow sensor 91, thereby regulating the diversion of oil.

[0029] The upper surface of the controller 9 is equipped with an indicator light 93, which is connected to the controller 9. When the controller 9 receives an abnormal signal, the indicator light 93 will light up to remind the staff that there is an abnormal problem with the device.

[0030] Both the inner walls of the cylinder 62 and the box 5 are provided with a corrosion-resistant coating. The corrosion-resistant coating is a component made of epoxy phenolic anti-corrosion coating, which reduces the corrosion of them by oil and extends their service life.

[0031] Specifically, when oil flows from the underground pumping pipe 7 to the pumping pump A2, it first enters the inlet pipe A61, which is located above the wind turbine 65. Therefore, when the oil enters the cylinder 62, the impact force generated by the oil flow acts on the wind turbine 65, thereby driving the wind turbine 65 to rotate around the shaft. The rotation of the wind turbine 65 drives the connected rod 66 to rotate synchronously. Therefore, the cleaning brush 67 sleeved on the outer surface of the connecting rod 66 also rotates. At the same time, after passing through the wind turbine 65, the oil flows to the filter screen 68. The filter screen 68 filters the oil, intercepting impurities and preventing them from entering the subsequent pumping pump A2 and causing blockage. This causes one side of the rotating cleaning brush 67 to contact the filter screen 68, thereby cleaning the filter screen 68 and brushing off the impurities intercepted on the filter screen 68 to prevent blockage of the oil flow. Then, the cover plate 63 is removed to replace and clean the anti-clogging components. This not only greatly improves the continuity and efficiency of the oil pumping operation, but also makes maintenance more convenient. The filtered oil then enters the housing 5 sequentially through the inlet pipe B69 and connecting pipe A81. The oil in chamber A51 is then pumped by oil pump A2 and flows through connecting pipe B82 and outlet pipe 3 into an external oil storage device. Furthermore, flow sensors 91 in the inlet pipe A61 and the diversion pipe A84 detect the flow rate of oil in their respective pipes and transmit signals to the controller 9, providing data reference for whether blockages have occurred during operation. The controller 9 controls the opening and closing of the solenoid valve 92 in the diversion pipe B86 based on the signals from the flow sensors 91, thereby regulating the oil diversion. Therefore, when the controller 9 receives an abnormal signal, the control indicator light 93 illuminates, alerting the operator to a problem with the equipment. This allows oil to be pumped from the filter screen 68 in the cylinder 62 into chamber B52 via oil pump B85, where it is then filtered by filter plate 83 and combined with the oil in chamber A51. Finally, since both the inner walls of the cylinder 62 and the box 5 are provided with corrosion-resistant coatings, which are made of epoxy phenolic anti-corrosion coatings, the corrosion of them by oil can be reduced, thus extending their service life.

[0032] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
