[0004] Therefore, we propose a high-precision downhole permanent guide point with a calibration mechanism to improve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision downhole permanent guide point with a calibration mechanism to solve the problems mentioned in the background art, such as inconvenient calibration and installation locations, easy deviation, and inconvenience for installing infrared transmitters.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-precision downhole permanent guide point with a calibration mechanism, comprising an installation sleeve, wherein a forked copper plate is installed inside the installation sleeve, a fixing frame is installed at the bottom end of the installation sleeve, a bidirectional screw is arranged between the forked copper plates, and a calibration mechanism for easy calibration is provided at the top end of the bidirectional screw.

[0007] The calibration mechanism includes a support sleeve, an infrared emitter, and a first bolt. A fixing sleeve is provided at the middle position of the outside of the bidirectional screw. A support rod is fixedly connected to the top of the fixing sleeve. A support sleeve is provided at the top of the outside of the support rod. An infrared emitter is installed at the top of the support sleeve. An adjustment hole is opened inside the support rod. A first bolt is installed inside the adjustment hole. Fixing blocks are fixedly connected to the front and rear ends of the bottom of the fixing sleeve. Fixing holes are opened inside the fixing blocks. A second bolt is installed inside the fixing holes.

[0008] As a further technical solution of this utility model, the support sleeve is movably sleeved on the top of the support rod, and the support sleeve is fixed to the outside of the support rod by the first bolt and the adjustment hole.

[0009] As a further technical solution of this utility model, the adjustment holes are provided in multiple sets, and the adjustment holes are arranged at equal intervals inside the support rod. The fixing sleeve is installed at the middle position outside the bidirectional screw through the second bolt and the fixing hole.

[0010] As a further technical solution of this utility model, a threaded sleeve is fixedly connected to the top of the forked copper sheet near the middle side, and protective sleeves are provided on the left and right sides of the bidirectional screw near the middle outer side.

[0011] As a further technical solution of this utility model, the threaded sleeve is disposed on the left and right sides outside the bidirectional screw, and the threaded sleeve and the bidirectional screw are connected by threads.

[0012] As a further technical solution of this utility model, the left and right sides of the outer side of the bidirectional screw are machined with external threads that cooperate with the internal threads, and the threads on the left and right sides of the outer side of the bidirectional screw are opposite.

[0013] As a further technical solution of this utility model, a connecting block is provided at the bottom of the inside of the fixing frame, and buffer springs are fixedly connected to the connecting block and the left and right sides of the top of the inside of the fixing frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the high-precision downhole permanent guide point with calibration mechanism not only facilitates calibration of the installation position and easy adjustment of the distance between the bifurcated copper plates to fix the device, but also facilitates the avoidance of measurement line breakage;

[0016] (1) By setting up a support sleeve, an infrared transmitter, a first bolt, a fixing sleeve, an adjustment hole, a support rod, and a second bolt, the infrared transmitter allows the staff to easily judge the position of the sleeve, thereby facilitating the calibration of the installation position of the device and preventing the device from accidentally shifting and affecting subsequent use. The fixing sleeve is placed in the middle position outside the bidirectional screw rod. After the fixing sleeve is placed, the second bolt is screwed into the inside of the fixing hole to limit and fix the fixing block. The fixing sleeve is fixed in the middle position outside the bidirectional screw rod, which allows the infrared transmitter to be installed and fixed.

[0017] (2) By setting up a threaded sleeve, a double-ended screw and a protective sleeve, the installation sleeve is inserted into the hole. After insertion, the protective sleeve is rotated. The protective sleeve drives the double-ended screw to rotate inside the threaded sleeve. Since the threads on the left and right sides of the protective sleeve are opposite, and the threaded sleeve and the double-ended screw are threadedly connected, the rotation of the double-ended screw can make the threaded sleeve press against the bifurcated copper piece, causing the bifurcated copper piece to move outward and fix the installation sleeve inside the hole.

[0018] (3) By setting up a connecting block, wire hole, buffer spring and damper, the measuring wire is installed inside the wire hole. When the measuring wire falls, the buffer spring buffers the measuring wire and the bottom of the measuring wire with its own elasticity, thereby reducing the impact force of falling, protecting the measuring wire, preventing the measuring wire from breaking, and increasing the service life of the measuring wire.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4The present invention provides an embodiment of a high-precision downhole permanent guide point with a calibration mechanism, comprising an installation sleeve 1, a forked copper plate 2 installed inside the installation sleeve 1, a fixing frame 10 installed at the bottom end of the installation sleeve 1, a bidirectional screw 4 arranged between the forked copper plates 2, and a calibration mechanism for easy calibration at the top end of the bidirectional screw 4.

[0026] The calibration mechanism includes a support sleeve 5, an infrared emitter 6, and a first bolt 7. A fixing sleeve 9 is provided at the middle position of the outside of the bidirectional screw 4. A support rod 16 is fixedly connected to the top of the fixing sleeve 9. A support sleeve 5 is provided at the top of the outside of the support rod 16. An infrared emitter 6 is installed at the top of the support sleeve 5. An adjustment hole 15 is opened inside the support rod 16. A first bolt 7 is provided inside the adjustment hole 15. Fixing blocks 19 are fixedly connected to the front and rear ends of the bottom of the fixing sleeve 9. Fixing holes 18 are opened inside the fixing blocks 19. A second bolt 17 is provided inside the fixing holes 18.

[0027] The support sleeve 5 is movably sleeved on the top of the support rod 16. The support sleeve 5 is fixed to the outside of the support rod 16 by the first bolt 7 and the adjustment hole 15. There are multiple sets of adjustment holes 15. The adjustment holes 15 are arranged at equal intervals inside the support rod 16. The fixing sleeve 9 is installed at the middle position outside the double screw 4 by the second bolt 17 and the fixing hole 18.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the infrared emitter 6 allows workers to easily determine the position of the sleeve, thus facilitating the calibration of the device's installation position and preventing accidental displacement that could affect subsequent use. The fixing sleeve 9 is placed on the middle position outside the bidirectional screw 4. After the sleeve is in place, the second bolt 17 is screwed into the fixing hole 18 to limit and fix the fixing block 19, thus fixing the fixing sleeve 9 on the middle position outside the bidirectional screw 4, which allows the infrared emitter 6 to be installed and fixed.

[0029] A threaded sleeve 3 is fixedly connected to the top of the forked copper plate 2 near the middle side. Protective sleeves 8 are provided on the left and right sides of the double-acting screw 4 near the middle. The threaded sleeve 3 is provided on the left and right sides of the double-acting screw 4. The threaded sleeve 3 and the double-acting screw 4 are threadedly connected. The left and right sides of the double-acting screw 4 are machined with external threads that match the internal threads. The threads on the left and right sides of the double-acting screw 4 are opposite.

[0030] Specifically, such as Figure 1 and Figure 2As shown, the mounting sleeve 1 is inserted into the hole. After insertion, the protective sleeve 8 is rotated. The protective sleeve 8 drives the double-acting screw 4 to rotate inside the threaded sleeve 3. Since the threads on the left and right sides of the protective sleeve 8 are opposite, and the threaded sleeve 3 and the double-acting screw 4 are threadedly connected, the rotation of the double-acting screw 4 can cause the threaded sleeve 3 to press against the forked copper piece 2, causing the forked copper piece 2 to move outward and fix the mounting sleeve 1 inside the hole.

[0031] A connecting block 11 is provided at the bottom of the inside of the fixed frame 10. Buffer springs 13 are fixedly connected to the connecting block 11 and the left and right sides of the top of the inside of the fixed frame 10. A damper 14 is provided inside the buffer spring 13. A wire hole 12 is opened inside the connecting block 11. The damper 14 is located on the left and right sides between the connecting block 11 and the inside of the fixed frame 10. The buffer springs 13 are symmetrically distributed about the vertical center line of the connecting block 11.

[0032] Specifically, such as Figure 1 and Figure 4 As shown, the measuring line is installed inside the wire hole 12. When the measuring line descends, the buffer spring 13 uses its own elasticity to buffer the measuring line and the bottom of the measuring line, thereby reducing the impact force of falling, protecting the measuring line, preventing the measuring line from breaking, and increasing the service life of the measuring line.

[0033] Working principle: In use, the mounting sleeve 1 is inserted into the hole. After insertion, the protective sleeve 8 is rotated, which drives the bidirectional screw 4 to rotate inside the threaded sleeve 3. Since the threads on the left and right sides of the protective sleeve 8 are opposite, and the threaded sleeve 3 and the bidirectional screw 4 are threadedly connected, the rotation of the bidirectional screw 4 can cause the threaded sleeve 3 to press against the forked copper piece 2, causing the forked copper piece 2 to move outward and fix the mounting sleeve 1 inside the hole. The measuring wire is installed inside the wire hole 12. When the measuring wire descends, the buffer spring 13 uses its elasticity to support the measuring wire and its bottom end. The infrared emitter 6 is cushioned to reduce the impact of falling, protect the measuring line from breakage, and increase its service life. The position of the sleeve can be easily determined by the staff, which facilitates the calibration of the device's installation position and prevents the device from accidentally shifting and affecting subsequent use. The fixing sleeve 9 is placed on the middle position outside the double-acting screw 4. After it is put on, the second bolt 17 is screwed into the inside of the fixing hole 18 to limit and fix the fixing block 19. The fixing sleeve 9 is fixed on the middle position outside the double-acting screw 4, and then the infrared emitter 6 can be installed and fixed.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
