[0040] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0041] See also Figures 1-8 As shown, the present invention provides a docking device for a well logging instrument, comprising a tower 1 erected in a well logging area, an operating table 2 3 and an operating table 1 2 being sequentially arranged on the outside of the tower 1 from top to bottom, a traction roller 4 for winding a cable being installed in the operating table 2 3, a support plate 7 vertically arranged and reinforced by a reinforcing rod being provided in the operating table 1 2, a surface limited sliding of the support plate 7 being provided with an upper bearing plate 8 that does not move simultaneously and supports the well logging instrument module 1 and a lower bearing plate 9 that supports the well logging instrument module 2, the lower bearing plate 9 being provided below the upper bearing plate 8, a clamping unit 2 20 that fixes the well logging instrument module 1 being slidably provided above the upper bearing plate 8, and a clamping unit 3 16 that is vertically collinear with the well logging instrument module 1 and fixes the well logging instrument module 2 being provided below the upper bearing plate 8;

[0042] A segmented docking assembly for transferring the logging instrument module to the second clamping unit 20 and the third clamping unit 16 is installed on the side of the operating table 1 2 away from the support plate 7;

[0043] The end of the cable is provided with a connector 17, the outside of the connector 17 is rotatably connected to a clamping head seat 18, and the outside of the clamping head seat 18 is a regular hexagon;

[0044] A connecting plate 27 is installed on one side above the support plate 7, and an automatic tightening assembly for threading the chuck seat 18 onto one end of the logging instrument module is installed below the connecting plate 27;

[0045] The automatic tightening assembly includes a fixing member 26 and a fitting member 19 used in conjunction with the chuck seat 18. The outer surfaces of the fixing member 26 and the fitting member 19 are both provided with a tooth block 22. A rotating frame 25 is mounted on one side of the fixing member 26. A driving gear 23 that meshes with the tooth block 22 is rotatably mounted on the end of the rotating frame 25.

[0046] At the operating table 2, the various modules of the logging instrument are arranged in sequence. That is, the logging instrument module 1 is installed first. In the assembled state, the lower bearing plate 9 is slid open and away, while the upper bearing plate 8 above is in a supporting state. The logging instrument module 1 is transferred by the segmented docking assembly, and the upper bearing plate 8 supports the bottom of the logging instrument module 1 to complete the positioning and placement. Then, the clamping unit 20 fixes the outside of the logging instrument module 1.

[0047] Next, the logging instrument module 2 is transferred from the segmented docking assembly. During this transfer, the height of the segmented docking assembly changes (drops). Correspondingly, the upper bearing plate 8 automatically slides out of the supporting position, while the lower bearing plate 9 is in the supporting state. Since the logging instrument module 1 has been fixed by the clamping unit 20, it will not fall. Then the logging instrument module 2 is vertically placed on the lower bearing plate 9 and fixed by the clamping unit 3 16. At this time, the logging instrument module 1 and the logging instrument module 2 are in the same vertical line, which facilitates their docking assembly.

[0048] Then, the second clamping unit 20 is moved downward in the vertical direction, so that the well logging instrument module 1 and the well logging instrument module 2 are quickly plugged into each other;

[0049] After the connection is completed, the second clamping unit 20 is moved upward in the vertical direction, and the logging instrument is moved upward as a whole, wherein the logging instrument module 1 is connected to the connector 17;

[0050] During the process of plugging the connector 17, the chuck seat 18 enters the fitting 19 and the fixing 26, and the fitting 19 and the fixing 26 jointly restrict the chuck seat 18, and then the driving gear 23 drives the gear block 22, thereby causing the chuck seat 18 in which the fitting 19 and the fixing 26 are fitted to rotate. At this time, the chuck seat 18 is threadedly sleeved on the end of the logging instrument module 1 to achieve a firm connection. Through the above process, high-precision automated docking and assembly operations between logging instrument modules and with the upper connector 17 can be achieved, significantly improving assembly efficiency and docking stability, and reducing manual intervention and error risks.

[0051] It should be noted that after all modules are connected, power-on test, communication test and data sampling check should be carried out to ensure that the connection is complete and the signal is continuous.

[0052] See Figure 5As shown, the automatic tightening assembly further includes electromagnets 21 embedded in the edges of both sides of the fixing member 26, and the rod body connected to the armature in each electromagnet 21 is fixed to the edges of both sides of the fitting member 19;

[0053] A fixing seat is provided on the support plate 7, and a rotating unit 24 for driving the rotating frame 25 to rotate is installed on the fixing seat. The rotating unit 24 is a rotating motor;

[0054] A rail groove 28 is installed at the bottom of the connecting plate 27 for limiting the sliding movement of the fitting 19 and the fixing member 26. A horizontal rail 29 is provided on one side of the rail groove 28 for limiting the sliding movement of the fitting 19 when it is opened. The horizontal rail 29 is used to limit the sliding range of the fitting 19 in the "open state" to prevent excessive opening or misalignment.

[0055] When powered on, the electromagnet 21 attracts the armature, driving the fitting 19 to move inward along the horizontal rail 29 until it fits into the clamping head seat 18, completing the restriction and covering of the clamping head seat 18;

[0056] By rotating the rotating unit 24, the driving gear 23 on the rotating frame 25 engages with the gear block 22, completing the thread tightening and locking process of the chuck seat 18;

[0057] The fitting part 19 moves inward on the horizontal rail 29 to a position communicating with the rail groove 28. Through the rotation of the fitting part 19 and the fixing part 26, since the fitting part 19 is now embedded in the rail groove 28, its rotational movement is constrained by the rail groove 28, and it completes an orderly rotation under its guidance, thereby driving the clamping head seat 18 to engage with the end thread of the logging module 1 and complete the locking action.

[0058] See Figure 3 As shown, the segmented docking assembly includes a lifting unit 12, a pushing end of the lifting unit 12 is provided with a flip unit 13, and the flip unit 13 includes a supporting base plate and a flip plate rotatably connected to the supporting base plate;

[0059] The upper end surface of the flip plate is installed with a lifting unit 2 14, and the pushing end of the lifting unit 2 14 is installed with a clamping unit 15 for fixing the logging instrument module 1;

[0060] The lifting unit 12 is used to control the vertical height of the entire flip structure and adjust the posture of the logging module after the height is determined;

[0061] The flip unit 13 adopts the existing method of driving the transmission rod with a lead screw to complete the posture adjustment of the logging instrument module from horizontal to vertical.

[0062] The second lifting unit 14 is used to accurately place the logging instrument module into the designated position of the upper bearing plate 8 and the lower bearing plate 9 after the flip angle is adjusted.

[0063] See Figure 3As shown, a drive shaft 10 driven by a motor is installed inside the operating table 1 2 , and two eccentric wheels 11 are sleeved on the outside of the drive shaft 10 . The two eccentric wheels 11 are arranged 180 degrees apart, and the eccentric wheels 11 are arranged in contact with the upper bearing plate 8 and the lower bearing plate 9;

[0064] The outer parts of the upper bearing plate 8 and the lower bearing plate 9 are both sleeved with elastic members, and the ends of the elastic members are fixed to the side surfaces of the support plate 7;

[0065] When the motor drives the drive shaft 10 to rotate, the two sets of eccentric wheels 11 generate alternating radial thrusts, thereby driving the upper bearing plate 8 and the lower bearing plate 9 to slide open or close alternately on the support plate 7, adapting to the alternating support of the logging instrument module.

[0066] See Figure 2 、 Figure 7 and Figure 8 As shown, a cleaning box 6 for removing dirt from the surface of the cable is provided in the operating table 2 3, and a traction roller 4 is installed on the top and bottom surfaces of the tower 1;

[0067] The cleaning box 6 is provided with a primary cleaning chamber and a secondary cleaning chamber. After the secondary cleaning, the material is dried and sent out through the annular air duct, and is guided and contacted with the guide wheel 5 and then wound by the traction roller 4.

[0068] A sliding frame 31 that reciprocates vertically is provided in both the primary cleaning chamber and the secondary cleaning chamber. The cable passes vertically through the opening of the sliding frame 31. A finger cylinder 33 is installed on the inner wall of one side of the sliding frame 31. Both driving ends of the finger cylinder 33 are rotatably connected to a laminating roller 32 that rolls in contact with the surface of the cable.

[0069] The primary cleaning chamber and the secondary cleaning chamber are both equipped with electric push rods 30 that push the corresponding sliding frames 31 to move synchronously. The ends of the sliding frames 31 are equipped with guide frames 34 that slide and fit in contact with the inner walls of the primary cleaning chamber and the secondary cleaning chamber.

[0070] The primary cleaning chamber contains an alkaline degreasing agent, which is used to preliminarily remove oil, mud and heavy contamination attachments on the surface of the cable;

[0071] When the cable is retracted, in order to remove well fluid, mud, oil and other attachments, it passes through the primary cleaning chamber and the secondary cleaning chamber in turn, and passes through the opening center of the two sliding frames 31. Then, the finger cylinder 33 drives the two laminating rollers 32 to approach each other, so that the laminating rollers 32 cover the outer surface of the cable, and the electric push rod 30 drives the sliding frame 31 to move back and forth in the vertical direction, so that the laminating rollers 32 perform dynamic rolling brushing on the surface of the cable. In one movement, the setting of the guide frame 34 limits the deviation of the sliding path, enhances stability, completes the cleaning of the two cleaning chambers, and roughly washes in the primary cleaning chamber.

[0072] In the primary cleaning chamber, the laminating roller 32 moves up and down under the action of the alkaline degreasing agent medium to perform rough cleaning and degreasing;

[0073] In the secondary cleaning chamber, the laminating roller 32 further cleans the residual oil film and fine particles in the neutral cleaning liquid to improve the surface cleanliness of the cable. The two sliding frames 31 and the laminating roller 32 work together to complete the entire cleaning task of the cable, greatly improving its cleaning uniformity and surface cleanliness.

[0074] When the present invention is in use, the logging instrument module is positioned on the upper and lower bearing plates 8 and 9 at different heights by means of the segmented docking assembly and fixed by the corresponding clamping unit 20 and the clamping unit 3 16. At this time, the logging instrument module 1 and the logging instrument module 2 are in the same vertical line, which facilitates their docking assembly. Then, by moving the clamping unit 20 downward in the vertical direction, the logging instrument module 1 and the logging instrument module 2 are quickly plugged in. By moving the clamping unit 20 upward in the vertical direction, the logging instrument as a whole is moved upward, and the logging instrument module 1 is plugged into the connector 17. The chuck seat 18 enters the fitting 19 and the fixing part 26, and the fitting 19 and the fixing part 26 jointly restrict the chuck seat 18, and then the driving gear 23 drives the gear block 22, thereby causing the chuck seat 18 in which the fitting 19 and the fixing part 26 are fitted to rotate. At this time, the chuck seat 18 is threadedly sleeved on the end of the logging instrument module 1 to achieve a firm connection. Through the above process, high-precision automated docking and assembly operations between logging instrument modules and with the upper joint 17 can be achieved, significantly improving assembly efficiency and docking stability, and reducing manual intervention and error risks.

[0075] The segmented docking assembly is used to adjust the height and flip angle of the logging instrument module. In conjunction with the lifting unit 2 14, the logging instrument module is accurately placed in the designated position of the upper bearing plate 8 and the lower bearing plate 9, thereby improving the alignment accuracy.

[0076] The upper and lower bearing plates 8 and 9 move at different times, which facilitates the sequential placement of the logging instrument module. When the upper bearing plate 8 exits the supporting position and the lower bearing plate 9 below positions the logging instrument module, it is convenient to align and assemble it.

[0077] By setting up a primary cleaning chamber and a secondary cleaning chamber, the finger cylinder 33 drives the two laminating rollers 32 to approach each other, so that the laminating rollers 32 cover the outer surface of the cable, and the electric push rod 30 drives the sliding frame 31 to move back and forth in the vertical direction. Under the action of the alkaline degreaser medium in the primary cleaning chamber, the laminating rollers 32 move up and down to perform rough cleaning and degreasing. The laminating rollers 32 further clean the residual oil film and fine particles in the neutral cleaning liquid in the secondary cleaning chamber to improve the cleanliness of the cable surface. The two sliding frames 31 and the laminating rollers 32 work together to complete the entire cleaning task of the cable, greatly improving its cleaning uniformity and surface cleanliness.

[0078] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
