[0018] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0019] In the description of the present invention, unless otherwise specified, "multiple" means two or more; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] See also Figures 1 to 3 The utility model provides a technical solution: an anti-clogging external filtering device for an oil pump, comprising an input pipe 1 and an output pipe 2, a fixed block 16 is fixed on the inner side of the input pipe 1, a spherical groove 3 is opened inside the fixed block 16, an oil inlet 4 is opened at the outer bottom of the fixed block 16, and oil outlets 5 are opened on both sides of the fixed block 16, two supports are fixed on the front side of the input pipe 1, a worm 6 is rotatably connected between the two supports, a handle 7 is fixed at one end of the worm 6, a turbine 8 is meshingly connected on the outer side of the worm 6, one end of the rotating shaft of the turbine 8 passes through the interior of the input pipe 1 and is coaxially fixed with a baffle 9, the outer side of the baffle 9 is in sliding contact with the inner side of the spherical groove 3, a limit rod 10 is fixed on the outer side of the turbine 8, and limit blocks 11 are arranged on both sides of the limit rod 10, and the limit blocks 11 are One end is fixedly connected to the outside of the input pipe 1, and both ends of the input pipe 1 are fixed with filter cartridges 12, and both ends of the output pipe 2 are respectively fixedly connected to the outsides of the two filter cartridges 12, and the upper end of the filter cartridge 12 is threadedly connected with an upper cover 13, and a filter element 14 is arranged inside the filter cartridge 12, and two one-way valves 15 are fixed on the inner side of the output pipe 2. The input pipe 1 is in a Y-shaped structure, and the fixing block 16 is in a cylindrical structure. The fixing block 16 is located at the intersection of the input pipe 1, and the baffle 9 is in a circular structure. The diameter of the baffle 9 is the same as the diameter of the spherical groove 3, and the center of the baffle 9 coincides with the center of the spherical groove 3. The interior of the filter cartridge 12 is connected to the interior of the input pipe 1, and the output pipe 2 is in a T-shaped structure. The interior of the output pipe 2 is connected to the interior of the filter cartridge 12, and the two one-way valves 15 face opposite directions;

[0022] The oil pump drives the oil to pass through the input pipe 1, the filter element 14, the filter cartridge 12, and the output pipe 2 in sequence. During this process, the one-way valve 15 allows the oil to only flow out from the filter cartridge 12. When the filter cartridge 14 needs to be replaced, the worm 6 is driven to rotate by turning the handle 7, and the worm 6 drives the turbine 8 to rotate. The turbine 8 drives the baffle 9 to rotate through the rotating shaft. The baffle 9 was originally at an angle of forty-five degrees, blocking one of the oil outlets 5. As the baffle 9 rotates ninety degrees to a negative forty-five degree angle, the other oil outlet 5 is blocked, causing the previously blocked oil outlet 5 to leak, causing the oil to be discharged from the other end of the input pipe 1 and enter the filter cartridge 12 at the other end, while the oil path in the original filter cartridge 12 is cut off. Through the above process, the filter cartridge 14 can be replaced without shutting down the oil pump, thereby avoiding the problem of shutting down the oil pump when replacing the filter cartridge 14, thereby affecting the progress of the oil pumping work.

[0023] Specific usage and function of this embodiment: When the filter element 14 needs to be replaced, the utility model drives the worm 6 to rotate by rotating the handle 7, and the worm 6 drives the turbine 8 to rotate, and the turbine 8 drives the baffle 9 to rotate through the rotating shaft. The baffle 9 was originally at an angle of forty-five degrees, blocking one of the oil outlets 5. As the baffle 9 rotates ninety degrees to a negative forty-five degree angle, the other oil outlet 5 is blocked, so that the originally blocked oil outlet 5 leaks, so that the oil is discharged from the other end of the input pipe 1 and enters the filter cartridge 12 at the other end, and the oil path in the original filter cartridge 12 is cut off.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
