[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figure 1-4As shown, this utility model provides a technical solution for a lithium-ion battery-powered high-efficiency automatic oil extraction device, including an external oil pipe 1, a filter screen 2 connected to the bottom end of the external oil pipe 1, a top of the external oil pipe 1 detachably connected to the bottom inner side of a connecting pipe 3, a handheld motor housing 4 connected to the top of the connecting pipe 3, and a removable lithium battery 5 detachably connected to one side of the handheld motor housing 4, an inner rotating rod 6 rotatably connected to the inner side of the external oil pipe 1, a spiral shaft 7 provided at the bottom edge of the inner rotating rod 6, the edge of the spiral shaft 7 fitting against the inner wall of the external oil pipe 1, and a side oil outlet pipe 8 connected to the inside of the connecting pipe 3.

[0024] The power output shaft of the motor inside the handheld motor housing 4 is connected to the transmission key seat 9 of the gearbox. The input end of the motor inside the handheld motor housing 4 is electrically connected to the output end of the removable lithium battery 5. The removable lithium battery 5 is a lithium battery of various voltages. A switch is provided on the handheld part of the handheld motor housing 4. The power output end of the motor inside the handheld motor housing 4 is connected to a reduction gearbox, and the power output shaft of the gear reduction gearbox is connected to the transmission key seat 9, which facilitates power supply through the removable lithium battery 5. The power transmitted by the motor is reduced through the gear reduction gearbox, which facilitates stable rotation of the inner rotating rod 6 and facilitates continuous extraction of viscous oil. The top of the inner rotating rod 6 is keyed to the transmission key seat 9 through the transmission key 10. The inner side of the top of the connecting pipe 3 is connected to the inner rotating rod 6. The rods 6 are connected by an oil seal bearing 11. The bottom of the handheld motor housing 4 and the top of the connecting pipe 3 are both fixedly connected to mounting blocks 12, and each corner of the mounting blocks 12 is provided with a bolt fixing seat 13. The mounting blocks 12 on the side of the handheld motor housing 4 and the connecting pipe 3 are detachably connected by bolt fixing seats 13, and the bolt fixing seats 13 on the side of the two mounting blocks 12 are connected by bolts. This makes it easy to quickly connect and fix the two mounting blocks 12 by bolt fixing seats 13, and also makes it easy to quickly disassemble and assemble the handheld motor housing 4 and the connecting pipe 3 by convenient disassembly and installation of the two mounting blocks 12. This further facilitates the flexible and convenient disassembly and installation of the oil extraction pipe structure and the drive equipment, reducing the difficulty of assembly.

[0025] An internal limiting ring 14 is provided at the bottom inner side of the connecting pipe 3. An extrusion groove 15 is provided on the bottom inner side of the internal limiting ring 14. An external support ring 16 is fixedly connected to the top outer side of the external insertion oil pipe 1. A threaded sleeve 17 is provided at the top edge of the external support ring 16. An extrusion sealing block 18 is provided at the top of the external insertion oil pipe 1 corresponding to the extrusion groove 15. A threaded pipe 22 is provided at the bottom of the connecting pipe 3. The threaded sleeve 17 is connected to the outside of the threaded pipe 22 by threads. After the threaded pipe 22 is completely connected to the inside of the threaded sleeve 17, the extrusion sealing block 18 at the top of the external insertion oil pipe 1 is squeezed into the extrusion groove 15. This facilitates the extrusion sealing block 18 at the top of the external insertion oil pipe 1 to be squeezed into the extrusion groove 15 under the extrusion action after the threaded sleeve 17 and the threaded pipe 22 are connected in place. This achieves the sealing treatment between the top of the external insertion oil pipe 1 and the inner wall of the connecting pipe 3, ensuring the tightness and stability of the connection.

[0026] The working principle and usage process of this utility model: In the actual application of this lithium-ion electric high-efficiency automatic oil pumping device, when assembling and connecting the oil pumping device, the inner rotating rod 6 and the spiral shaft 7 are first inserted upward from the bottom of the outer insertion oil pipe 1. Then, the filter screen 2 is connected to the bottom of the outer insertion oil pipe 1. Then, the inner rotating rod 6 is connected to the transmission key seat 9 at the end of the motor output shaft inside the handheld motor housing 4 through the transmission key 10 at its top. Finally, the mounting block 12 at the side of the handheld motor housing 4 and the connecting pipe 3 is locked and fixed by the bolt fixing seat 13. This facilitates the quick connection between the connecting pipe 3 and the handheld motor housing 4, and makes it easy to flexibly and conveniently disassemble and install the oil pumping pipe structure and the drive device, reducing the difficulty of assembly.

[0027] Next, after the inner rotating rod 6 is assembled, the connecting pipe 3 needs to be connected to the outer insertion oil pipe 1. During the connection, the outer insertion oil pipe 1 is rotated so that the threaded sleeve 17 at the top of the outer insertion oil pipe 1 is rotated into the outer side of the threaded pipe 22 at the bottom of the connecting pipe 3 under the action of the thread. After the threaded sleeve 17 and the threaded pipe 22 are fully aligned, the compression sealing block 18 at the top of the outer insertion oil pipe 1 will enter the compression groove 15 inside the built-in limiting ring 14. This achieves the sealing treatment between the top of the outer insertion oil pipe 1 and the inner wall of the connecting pipe 3, ensuring the tightness and stability of the connection. This not only facilitates the quick alignment and connection but also ensures that there will be no loosening during the oil extraction process and prevents oil leakage.

[0028] In the actual oil pumping process, the handheld motor housing 4 and the detachable lithium battery 5, combined with the power transmission key seat 9 and transmission key 10, facilitate the rotation of the rotating rod 6 and the screw shaft 7 in the gearbox by lithium battery drive. This drives the oil from the filter screen 2 into the external insertion oil pipe 1, and under the action of the screw shaft 7, it is lifted from the bottom to the top inside the external insertion oil pipe 1. Finally, the oil is discharged through the side oil outlet pipe 8, thus realizing convenient oil pumping operation. The detachable lithium battery 5 can be detachably connected to the side of the handheld motor housing 4, which is convenient for disassembly and replacement and easy to replenish power to meet the needs of long-term continuous operation.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
