[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0024] like Figs. 1-3 As shown, this embodiment proposes a cable delivery and take-up device for underground wells, including an aircraft plug mounting bracket 1, a cable guide device 2, a cable distribution frame 3, and a cable tray 4. The aircraft plug mounting bracket 1 is used to carry the aircraft plug. The cable guide device 2 is mounted on the aircraft plug mounting bracket 1 and includes a left directional guide wheel 21, a right directional guide wheel 22, a front guide wheel 23, and a downhole cable guide spool 24. The aircraft plug mounting bracket 1 has a frame structure with open top, front end, and bottom. The rotating shafts of the left directional guide wheel 21 and the right directional guide wheel 22 are vertically arranged and rotatably mounted on both sides of the upper front end of the aircraft plug mounting bracket 1, respectively. The front guide wheel 23... The rotating shaft is horizontally positioned and perpendicular to both sides of the frame structure. It is rotatably mounted below the left and right guide wheels 21 and 22. Preferably, there are three front guide wheels 23, each with a different vertical height, and they move sequentially towards the rear end of the frame structure in the horizontal direction. The left guide wheel 21 is cylindrical, and the front guide wheel 23 is a concave guide cylinder structure with a diameter decreasing from both sides to the middle. The left and right guide wheels 21 and 22 are aluminum guide wheels, and the front guide wheel 23 is made of polytetrafluoroethylene (PTFE). When the cable is pulled out, the left and right guide wheels 21 and 22 act as guides, and the front guide wheel 23 acts as an assist mechanism, ensuring flexible and reliable cable retraction and installation.

[0025] At the bottom of the aircraft plug mounting bracket 1, a downhole cable reel 24 is bolted on. The downhole cable reel 24 extends into the cable distribution frame 3. During the cable winding and unwinding process, the cable can be routed along the cable reel to the cable distribution frame 3, thus spatially separating the crisscrossing cables.

[0026] The cable divider 3 is a plate-like structure with multiple through holes evenly arranged on it. The cable divider 3 is used to isolate cables in their respective areas by partitioning. A single well can hold up to four sets of aircraft plugs. Therefore, the cable divider 3 preferably divides the cable storage area into four isolated areas. In an optional embodiment, the cable divider 3 can be manufactured as a standard part. Multiple cable dividers 3 can be assembled and spliced ​​to obtain the required size, which is suitable for wells of different sizes.

[0027] The cable tray 4 is installed in the well to support the cable and prevent it from directly contacting the ground to avoid water immersion or scratches. The cable divider 3 is erected vertically on the cable tray 4. The cable tray 4 includes a grating plate 41, a square tube 42, and a fixing bracket 43. The square tube 42 is located at the bottom of the grating plate 41 to elevate the grating plate 41 and prevent water and dust accumulation in the well from damaging the intermediate frequency cable. The fixing bracket 43 is used to connect and fix the grating plate 41 and the square tube to prevent the grating plate 41 from shifting or deviating.

[0028] The working process of the cable reel-in / out device is briefly described below:

[0029] When the cable is in the retracted state, the cable reel is placed on the cable tray 4, and the cables in each reel are separated by the cable divider 3. When it is necessary to pull out the cable, the cable is guided along the downhole cable reel 24 by the left guide wheel 21 and the right guide wheel 22, and assisted by the front guide wheel 23, so that it can be easily pulled out. Due to the action of the cable reel and the cable divider 3, the cables are not easy to get tangled with each other. The cable retraction process is the reverse of the pulling process, and will not be described in detail here.

[0030] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
