[0002] Downhole equipment oiling maintenance is a powerful guarantee for the normal operation of the equipment. However, the oiling port of the current downhole equipment is usually small, and in the process of manually adding oil, the oil is easy to splash and waste everywhere, and the oiling efficiency is low and the time is long. At the same time, the downhole environment is dusty, and the open oiling process is easy to cause impurities, moisture and the like to enter the inside of the equipment oil port, causing oil pollution and directly affecting the safe operation and service life of the equipment.

[0014] like Figures 2-3 As shown: The upper end of the connecting ring 7 is connected to the lower end of the oil hose 5. The connecting ring 7 is connected to the mounting flange 8 by mounting bolts 9. The upper part of the outer wall of the second clamping head 12 and the lower part of the outer wall of the first clamping head 11 are both connected to clamping rings 14. The two clamping rings 14 are symmetrically arranged. The upper end of one clamping ring 14 and the lower end of the other clamping ring 14 are both inclined. The first clamping head 11 and the second clamping head 12 are equipped with filter blocks 15. An anti-slip pad is connected between the two clamping rings 14. The anti-slip pad is made of rubber. The connection between the connecting ring 7 and the oil hose 5 is used to enable fluid flow between the oil hose 5 and the filter mechanism, and the mounting bolt 9 facilitates the maintenance and assembly of the filter mechanism. The snap ring 14 serves as the locking force-bearing surface of the snap-fit mechanism.

[0015] like Figures 3-5 As shown: The inner wall of the support ring 16 is connected to the upper part of the outer wall of the lower oil pipe 13. There are four sets of guide rods 17. The upper ends of two guide rods 17 are connected to the lower end of the connecting ring 7. The outer walls of multiple guide rods 17 are slidably connected to sliders 18. One end of the sliders 18 is connected to the four sides of the outer wall of the first clamping head 11. The upper part of the outer walls of multiple guide rods 17 is connected to anti-slip sleeves 19. The support ring 16 is connected to the lower oil pipe 13 to fix the stabilizing mechanism to the oil pipeline. Four sets of guide rods 17 provide uniform guidance around the perimeter to ensure that the first clamping head 11 moves smoothly and without deviation. The guide rods 17 are connected to the connecting ring 7 to connect the upper structure and the stabilizing mechanism into a whole, enhancing the overall rigidity. The slider 18 connects the first clamping head 11 to the guide rods 17 and constrains its up and down movement on the vertical path determined by the guide rods 17. The slider 18 is connected to the first clamping head 11 to transfer the force of the first clamping head 11 to the slider 18 and make it move synchronously with the slider 18. The anti-slip sleeve 19 is used to provide frictional damping after the slider 18 moves to a suitable position, realizing the temporary suspension and fixation of the first clamping head 11 in the open position.
[0016] like Figures 3-5As shown: The mounting block 20 is fitted onto the lower part of the outer wall of the corresponding guide rod 17. One end of the rotating screw 22 extends through to one side of the connecting plate 21. The connecting plate 21 has a threaded hole corresponding to the rotating screw 22. The rotating screw 22 is located in the threaded hole. The upper and lower ends of the inner wall of the mounting block 23 are respectively inclined at the two locking rings 14. The upper and lower ends of the inner wall of the mounting block 23 are embedded with movable balls 24. The upper movable ball 24 contacts the upper end of the upper locking ring 14, and the lower movable ball 24 contacts the lower end of the lower locking ring 14. The cross-sectional shape of the mounting block 23 is an inverted V-shaped structure. Mounting block 20 can mount the clamping mechanism on guide rod 17. The upper and lower inclined parts of the inner wall of mounting block 23 are designed to cooperate with the inclined surface of clamping ring 14, converting the horizontal locking force into the vertical clamping force. Moving ball 24 converts the sliding friction between mounting block 23 and clamping ring 14 into rolling friction, reducing wear and making the locking operation more effortless.
[0017] like Figures 6-8 As shown: The fixing mechanism includes a connecting sleeve 25. The lower part of the connecting sleeve 25 is made of a flexible material. The upper end of the connecting sleeve 25 is installed on the lower part of the outer wall of the lower oil pipe 13. The cross-sectional shape of the connecting sleeve 25 is trumpet-shaped. The connecting sleeve 25 is fitted onto the upper part of the outer wall of the equipment oil inlet pipe 26. A support ring 27 is connected to the middle of the outer wall of the equipment oil inlet pipe 26. Each support ring 27 is circumferentially connected to the upper end of a support spring 28. Multiple support springs 28 are connected to the upper ends of movable rings 29. The movable rings 29 slide on the outer wall of the equipment oil inlet pipe 26. A sleeve 30 is connected to the outer wall of the movable rings 29. The sleeve 30 is fitted onto the upper part of the outer wall of the equipment oil inlet pipe 26. The sleeve 30 contains... The upper part of the wall is provided with mounting grooves 31. A compression spring 32 is connected to one side of the inner wall of the multiple mounting grooves 31. A compression block is connected to one end of the multiple compression springs 32. The multiple compression blocks slide inside the multiple mounting grooves 31 respectively. A compression ball 33 is embedded in one end of the multiple compression blocks. One side of the multiple compression ball 33 contacts the outer wall of the connecting sleeve 25. A compression groove 34 is provided on the outer wall of the equipment oil inlet pipe 26 corresponding to the multiple compression ball 33. The compression groove 34 is set in an arc structure. The multiple compression ball 33 squeezes the connecting sleeve 25 into the compression groove 34. A stop ring 35 is connected to the upper part of the outer wall of the connecting sleeve 25. The stop ring 35 contacts the upper end of the sleeve 30. The connecting sleeve 25 is used to achieve a sealed connection between the lower oil pipe 13 and the equipment oil inlet pipe 26. The flexible material below the connecting sleeve 25 can deform under pressure to tightly fit the outer wall of the equipment oil inlet pipe 26. The connecting sleeve 25 is flared to guide and accommodate the opening of the equipment oil inlet pipe 26, which facilitates initial alignment and insertion. The support ring 27 provides a lower support reference and installation base for the entire fixing mechanism. The support spring 28 provides an upward reset force and buffers the impact generated during connection. The moving ring 29 transmits the spring force of the support spring 28 to the sleeve 30 and serves as the sliding base of the sleeve 30. The mounting groove 31 is used to accommodate and guide the compression spring 32 and the compression block. The compression block is used to transmit the spring force and act directly on the compression ball 33. The compression ball 33 converts sliding friction into rolling friction, reducing wear and operating force during locking and unlocking. The compression groove 34 provides a precise locking position and force fulcrum for the compression ball 33. The compression ball 33 compresses the connecting sleeve 25 into the compression groove 34. This compression action is used to cause the flexible connecting sleeve 25 to undergo plastic deformation and embed into the compression groove 34, thereby achieving mechanical self-locking and high-pressure sealing. The abutment ring 35 can place the connecting sleeve 25 and the lower oil pipe 13 above the sleeve 30.
[0018] Working principle: When using this pneumatic refueling device, first, use your hand to push the sleeve 30 downwards so that it moves down along the equipment oil inlet pipe 26. Align the trumpet-shaped flexible connecting sleeve 25 at the front end of the device's lower oil pipe 13 with the opening of the equipment oil inlet pipe 26 and apply downward pressure to make the connecting sleeve 25 elastically deform and tightly wrap around the outer wall of the equipment oil inlet pipe 26 to form the first seal. Then, the sleeve 30 is released, and the multiple extrusion blocks inside it are pushed by the extrusion spring 32, causing the extrusion balls 33 at the front end to slide into the pre-set arc-shaped extrusion groove 34 on the oil inlet pipe 26 of the equipment. The multiple extrusion balls 33 tightly press the connecting sleeve 25 into the extrusion groove 34, while the abutment ring 35 contacts the upper end of the sleeve 30, ensuring the stability of the connection between the lower oil pipe 13 and the oil inlet pipe 26 of the equipment. After the pipeline is connected, the external air source is turned on, and compressed air enters the upper part of the oil storage tank 1 through the air inlet pipe 2, applying a uniform and stable pressure to the grease in the tank. The pressurized grease flows through the oil delivery hose 5 and the connecting pipe 6 in sequence, and enters the filter chamber composed of the locked first clamping head 11 and the second clamping head 12. When the grease passes through the filter block 15, the solid particles and other impurities contained therein are effectively intercepted, and purification is achieved. The clean grease continues to flow through the lower oil pipe 13 and is transported to the inside of the equipment oil inlet pipe 26 for oil injection into the equipment.
[0019] After the oil transfer is completed and the equipment is depressurized, disconnect the lower oil pipe 13 from the upper part of the equipment oil inlet pipe 26. Move the sleeve 30 downwards by hand to make the extrusion ball 33 exit from the extrusion groove 34, release the locking force, and then lift the lower oil pipe 13 upwards to make the connecting sleeve 25 detach from the equipment oil inlet pipe 26.
[0020] Then, the rotating screws 22 on both sides of the device are rotated counterclockwise. The rotation of the rotating screws 22 will drive the mounting block 23 connected to it to move outward horizontally, so that the moving ball 24 on its inner wall is disengaged from the inclined surface of the upper and lower locking rings 14. The inclined self-locking force provided by the mounting block 23 can be completely released. The slider 18 fixed to the outer wall of the first locking head 11 can be smoothly pushed upward by hand.
[0021] The slider 18 will slide upward along the guide rod 17, thereby driving the entire first clamping head 11 to move upward synchronously, separating it from the second clamping head 12, and continuously pushing the slider 18 upward. The inner wall of the slider 18 will be tightly clamped onto the outer wall of the anti-slip sleeve 19 at the top of the guide rod 17.
[0022] The anti-slip sleeve 19 serves as a temporary positioning and fixing element here, reliably supporting the entire weight of the slider 18 and the first mounting head 11 through friction, so that they are stably suspended at the highest position, thereby leaving the largest and safest working space for subsequent operations.
[0023] Once the first cartridge head 11 is securely fixed in the hovering position, the used filter block 15 is fully exposed inside the cavity of the second cartridge head 12. The operator can remove the filter block 15 directly by hand or with simple tools without any obstruction for cleaning or disposal.
[0024] When installing the filter block 15, the second mounting head 12, which contains the filter block 15, is positioned, and then the first mounting head 11 is aligned and lowered to initially close and form a filter cavity. Simultaneously, the rotating screws 22 located on both sides of the device are rotated clockwise. The rotation of the rotating screws 22 drives the mounting block 23 to push inward. Due to its precise inverted V-shaped inclined structure on its inner wall, and the embedded moving balls 24 respectively contacting the inclined surfaces of the upper and lower locking rings 14, the horizontal pushing force is efficiently converted into a strong clamping force in the vertical direction. This vertical force forces the locking rings 14 of the first mounting head 11 and the locking rings 14 of the second mounting head 12 to press tightly together and compress the rubber anti-slip pad located between them to the maximum extent, thereby forming a high-pressure seal between the first mounting head 11 and the second mounting head 12, and at the same time firmly pressing the filter block 15 in the preset working position.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
