Description

Technical Field

[0001] The present invention relates to the technical field of seismic observation, and particularly to a lifting assistance device for a long cable water temperature sensor in a seismic underground well. Background Art

[0002] Water temperature observation is one of the main observation means of a seismic geophysical network, recording the change of the underground water temperature at a certain depth below the water surface of an observation well over time. Studying the dynamic change process of the water temperature can well reflect the state of earthquake gestation, occurrence and post-earthquake adjustment. The depth of a seismic fluid observation well is generally several hundred meters or even more than one kilometer. A casing is provided in the fluid observation well, and the diameter of the casing is generally 100 mm - 200 mm, and some seismic fluid observation wells adopt variable-diameter casings. The water temperature sensor is installed at a certain depth underwater in the fluid well for long-term observation, and is connected to the equipment host through a long cable, converting the physical quantity temperature signal into an electrical signal, and then realizing data acquisition, processing, storage and transmission.

[0003] In actual water temperature observation, the supporting probe cable connected to the water temperature sensor has characteristics such as heavy weight and thin diameter. Due to the different installation depths of the water temperature sensors, the lengths of the supporting probe cables will also be several hundred meters or even more than one kilometer. Taking the commonly used SZW type water temperature instrument in seismic fluid stations as an example, the probe size is Φ30×690 mm, and when the length of the probe cable is 1000 m, the weight can reach about 44 kg, and the cable diameter is about 4 mm. The water temperature probe is in long-term observation underground, and it is inevitable to have failures, and the sensor needs to be updated or repaired in time to avoid affecting the continuity rate of the station's observation data.

[0004] However, during the operation of lifting or lowering the water temperature probe, there are situations such as being stuck due to the variable diameter of the underground casing or being trapped in the underground sludge, or the entanglement of multiple water temperature probe cables. Existing commercial products such as cable winders are difficult to meet the above requirements, and are prone to situations such as cable breakage. Therefore, at present, the lifting or lowering of the water temperature sensor and the probe cable mostly adopts manual operation, especially the lifting process of the long cable water temperature sensor is more difficult and requires the cooperation of multiple people. In comparison, the manual lifting and lowering method of the water temperature probe, although having high reliability, is time-consuming and laborious, and does not conform to the level of equipment automation and intelligence in the modern high-speed development. Therefore, there is an urgent need to design a lifting assistance device for a long cable water temperature sensor in a seismic underground well. Summary of the Invention

Detailed implementation manners

[0033] The following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings. It should be understood that the protection scope of the present invention is not limited by the specific implementation manners.

[0034] Unless otherwise clearly stated, throughout the specification and claims, the term "comprise" or its variations such as "comprises" or "including" etc. will be understood to include the stated elements or components, without excluding other elements or other components.

[0035] As Figures 1 to 10As shown, a lifting assistance device for a seismic downhole long cable water temperature sensor according to a preferred embodiment of the present invention includes a hoop 1, and the hoop 1 is used to install the device at the wellhead of a seismic fluid observation well. The hoop 1 is a well-known part in the relevant art of the field, and will not be elaborated here too much. The main body bracket is used to provide support for the device, and the main body bracket includes a support frame 2, a first fixing ring 3 and a second fixing ring 4.

[0036] As shown in Figure 1 , Figure 2 and Figure 10 shown, multiple groups of combined blocks 101 are arranged on the hoop 1, and combined bolts 102 penetrate through the combined blocks 101. Multiple groups of support frames 2 are provided, and a combined plate 201 is arranged at the bottom of each group of support frames 2, and multiple groups of reserved screw holes 202 are equidistantly arranged on the combined plate 201. Among them, the combined bolts 102 are matched with the reserved screw holes 202, and the combined blocks 101 and the combined plate 201 are locked and fixed through the combined bolts 102.

[0037] Specifically, as shown in Figure 1 , Figure 2 and Figure 10 shown, the combined blocks 101 and the combined plate 201 correspond one by one. After the combined plate 201 and the combined block 101 are attached, the combined bolts 102 are penetrated through the combined blocks 101 and screwed into the corresponding reserved screw holes 202, and then the combined blocks 101 and the combined plate 201 can be locked and fixed together, so as to assemble and fix the support frame 2 and the hoop 1. Since multiple groups of reserved screw holes 202 are equidistantly arranged on the combined plate 201, the support frame 2 can be assembled and fixed with hoops 1 of multiple specifications, so that hoops 1 of corresponding specifications can be assembled according to the size of the wellhead of the seismic fluid observation well, and the device can assemble hoops 1 of different specifications, and different specifications of hoops 1 are used to meet the installation and use at the wellheads of seismic fluid observation wells of different sizes, thereby improving the applicability of the device.

[0038] As shown in Figure 1 and Figure 2 shown, the first fixing ring 3 and the second fixing ring 4 are arranged in an upper and lower concentric structure on the support frame 2, which is convenient for the cable of the observation well to be transmitted to the middle. Multiple groups of snap rings 8 are installed on the first fixing ring 3 and the second fixing ring 4, and the snap rings 8 are of an open structure design. Multiple groups of snap rings 8 are respectively used to fix and separate multiple groups of cables, so that other cables are distributed along the edge, avoiding the situation of wire entanglement when the cables are lifted.

[0039] As shown in Figure 1 and Figure 2As shown, the guide rail 5 is vertically installed between the first fixed ring 3 and the second fixed ring 4. Sliding blocks 9 are respectively fixedly connected to both ends of the guide rail 5. Cross beams 6 are fixedly connected inside the first fixed ring 3 and the second fixed ring 4. The sliding blocks 9 at both ends of the guide rail 5 are respectively slidably connected to the cross beams 6 inside the first fixed ring 3 and the second fixed ring 4. Multiple groups of adjusting screw holes 7 are provided on the cross beam 6, and the multiple groups of adjusting screw holes 7 are equally spaced. Through the multiple groups of equally spaced adjusting screw holes 7, the limit fixation of the sliding block 9 at multiple positions on the cross beam 6 can be satisfied. A through hole is provided on the sliding block 9, and a limit bolt passes through the inside of the through hole. The adjusting screw hole 7 matches the limit bolt.

[0040] Specifically, the guide rail 5 is slidably connected between the cross beams 6 inside the first fixed ring 3 and the second fixed ring 4 through the sliding block 9, and is locked by the limit bolt. During the process of sliding and adjusting the guide rail 5, the guide rail 5 can be fixed at the required position by using the limit bolt. In this way, the position of the guide rail 5 can be flexibly adjusted in the diameter direction of the first fixed ring 3 and the second fixed ring 4, combined with adjusting the orientation of the clamping hoop 1 fixed at the wellhead of the seismic fluid observation well, so as to facilitate controlling the position of the water temperature cable during the lifting or lowering operation.

[0041] Refer to Figure 3 、 Figure 8 and Figure 9 As shown, a machine assistance mechanism, a manual lifting component, and a self-locking component are successively installed on the guide rail 5. Clamps 16 are installed on the machine assistance mechanism, the manual lifting component, and the self-locking component. The clamp 16 includes a straight cylinder 1601 and a limit seat 1602. Multiple groups of limit seats 1602 are fixedly connected inside the straight cylinder 1601. A clamping component is installed on the limit seat 1602. The clamping component can automatically clamp the cable during the ascending process of the straight cylinder 1601 and release the cable during the descending process of the straight cylinder 1601.

[0042] Refer to Figure 8 and Figure 9 As shown, the clamping component includes clamping rods 1603 and springs 1604. Multiple groups of clamping rods 1603 are movably hinged on the limit seat 1602. The springs 1604 are fixedly connected between the clamping rods 1603 and the straight cylinder 1601. One end of the spring 1604 is fixedly connected with a rubber head 1605, and the rubber head 1605 is made of fluororubber or silicone rubber. When the clamping rod 1603 clamps the cable, the rubber head 1605 can not only increase the friction between the clamping rod 1603 and the cable, making the cable clamping more stable, but also protect the cable to prevent the cable from being damaged due to excessive clamping pressure.

[0043] Among them, refer to Figure 9 As shown, one end of the straight cylinder 1601 is of an open type, and the cable can freely enter and exit the inside of the straight cylinder 1601 through the opening, facilitating the clamping and disassembly of the cable.

[0044] Specifically, the cable to be lifted from the seismic well enters the interior of the straight cylinder 1601 through the opening, and the position of the cable inside the straight cylinder 1601 is adjusted so that the cable is located between the multiple groups of clamping rods 1603. During the upward movement of the straight cylinder 1601, the clamping rods 1603 are subjected to the friction force with the cables and rotate downward with the hinge axis as the center. The simultaneous downward rotation of the multiple groups of clamping rods 1603 will squeeze the cables at the same time, and clamp the cables and fix them in the middle. During the downward movement of the straight cylinder 1601, the clamping rods 1603 are subjected to the friction force with the cables and rotate upward with the hinge axis as the center. The simultaneous upward rotation of the multiple groups of clamping rods 1603 will loosen the clamped cables.

[0045] In this way, the clamp 16 can automatically hold and release the cable. When the clamp 16 moves up, it automatically holds the cable so that the cable rises with the clamp 16. When the clamp 16 moves down, it automatically releases the cable so that the cable does not fall with the clamp 16. In this way, the cable can be automatically lifted by the up and down movement of the clamp 16.

[0046] Ginseng Figure 9 As shown, a wedge 25 is also installed at the opening of the clamp 16, and the wedge 25 is fixed at the opening by bolts. One end of the wedge 25 is inserted into the inside of the opening. By installing the wedge 25, the opening on the clamp 16 can be closed, so that the clamp 16 forms a closed whole. The structural strength of the clamp 16 itself is improved, the clamp 16 is evenly stressed, and it is not easy to deform, ensuring stable and reliable use.

[0047] Ginseng Figure 3 and Figure 4 As shown, the machine assist assembly is used to assist the lifting of the cable. The machine assist mechanism includes a mechanical arm 11 and a second slider 17. The mechanical arm 11 is fixedly mounted on the sliding block 9 at the top of the guide rail 5, and one end of the mechanical arm 11 is connected to the second slider 17. The second slider 17 is slidably connected to the guide rail 5, and the clamp 16 in the machine assist mechanism is fixedly mounted on the second slider 17.

[0048] Specifically, the mechanical arm 11 is a telescopic cylinder, and the mechanical arm 11 can vertically push and pull the second slider 17, so that the second slider 17 can be automatically lifted and lowered on the guide rail 5. The clamp 16 on the second slider 17 can lift the cable during the lifting process, thereby providing assistance to manually operate the cable lifting.

[0049] Ginseng Figure 5 and Figure 7As shown in the figure, a groove 22 is formed at one end of the second slider 17. A second pressure sensor 24 is installed at the top end inside the groove 22, and a first pressure sensor 23 is installed at the bottom end inside the groove 22. One end of the robotic arm 11 is fixedly installed with a connecting block 13, and the connecting block 13 is inserted into the inside of the groove 22. A control box 12 is fixedly installed on one side of the robotic arm 11, and both the first pressure sensor 23 and the second pressure sensor 24 are electrically connected to the control box 12.

[0050] Specifically, when the robotic arm 11 extends and retracts, the connecting block 13 at its one end drives the second slider 17 to move up and down. When rising, the connecting block 13 will squeeze the second pressure sensor 24 at the top end inside the groove 22, and the upward squeezing force of the connecting block 13 on the second pressure sensor 24 is the force for the robotic arm 11 to lift the cable. By the second pressure sensor 24, the force for the robotic arm 11 to lift the cable is monitored in real time. When the force for lifting the cable is too large, it indicates that the cable is blocked during the lifting process. At this time, the second pressure sensor 24 will send a warning signal to the control box 12, and the control box 12 controls the robotic arm 11 to stop working to prevent the cable from being pulled off.

[0051] When descending, the connecting block 13 will squeeze the first pressure sensor 23 at the bottom end inside the groove 22, and the downward squeezing force of the connecting block 13 on the first pressure sensor 23 is the force for the robotic arm 11 to lower the cable. By the first pressure sensor 23, the force for the robotic arm 11 to lower the cable is monitored in real time. When the force for lowering the cable is too large, it indicates that the cable is blocked during the lowering process. At this time, the first pressure sensor 23 will send a warning signal to the control box 12, and the control box 12 controls the robotic arm 11 to stop working to prevent the cable from being pulled off.

[0052] Refer Figure 3 and Figure 4 As shown in the figure, the manual lifting component is used to manually control the lifting of the cable. The manual lifting component includes a first slider 15, and the first slider 15 is slidably connected to the guide rail 5. The clamp 16 in the manual lifting component is fixedly installed on the first slider 15.

[0053] Refer Figures 3 to 5 As shown in the figure, a rocker arm assembly 10 is provided between the guide rail 5 and the first slider 15. Through the rocker arm assembly 10, it is convenient to manually control the first slider 15 to move up and down, so as to facilitate the manual operation to lift the cable, and the operability is relatively strong.

[0054] Refer Figures 3 to 5As shown in the figure, the rocker arm assembly 10 includes a bracket 1001, a closed ring 1002, a stud 1003, and a rocker arm 1004. The bracket 1001 is welded and fixed to one side of the guide rail 5. The closed ring 1002 is welded and fixed to one end of the first slider 15. The rocker arm 1004 is movably hinged to the bracket 1001. The stud 1003 is welded and fixed to one end of the rocker arm 1004, and the stud 1003 is inserted into the inside of the closed ring 1002.

[0055] Specifically, a handle is fixedly connected to one end of the rocker arm 1004. By means of the handle, it is convenient to press one end of the rocker arm 1004, so that the rocker arm 1004 rotates around the hinge axis with the bracket 1001 as the center. At this time, the stud 1003 at one end of the rocker arm 1004 will pry the closed ring 1002 to lift and lower. By reciprocatingly lifting and pressing the rocker arm 1004 up and down, the first slider 15 can be vertically lifted and lowered on the guide rail 5. The fixture 16 on the first slider 15 will lift the cable during the lifting and lowering process, so as to manually operate and lift the water temperature cable.

[0056] It should be noted that the distance between the hinge point of the rocker arm 1004 and the bracket 1001 and the handle is relatively long, and the distance between the hinge point and the stud 1003 is relatively short. Thus, the rocker arm 1004 can use the lever principle to pry the first slider 15 to lift and lower, which is more labor-saving.

[0057] See Figures 3 to 5 As shown in the figure, the self-locking assembly is used for self-locking and hovering after the cable is lifted. The self-locking assembly includes a fixed block 14. The fixed block 14 is fixedly connected to the outside of the guide rail 5. The fixture 16 in the self-locking assembly is fixedly installed on the fixed block 14.

[0058] Specifically, during the process of lifting the water temperature cable in cooperation with the machine assistance component and the manual lifting component, when the two sets of lifting fixtures 16 descend simultaneously, at this time the cable will lose its fixation. By setting a set of fixtures 16 that do not move, after the two sets of lifting fixtures 16 release the cable simultaneously, the non-moving fixture 16 can hold the cable tightly to prevent the cable from sliding down during the lifting process, ensuring the smooth progress of the cable lifting.

[0059] On the other hand, see Figure 3 and Figure 6 As shown in the figure, a rotating shaft 21 is rotatably connected to the fixed block 14, the first slider 15, and the second slider 17. A fixing plate 18 is fixedly connected to the rotating shaft 21. The fixture 16 is fixedly connected to the fixing plate 18. The fixture 16 and the fixing plate 18 can rotate and adjust around the rotating shaft 21. A fixing bolt 19 penetrates through the fixing plate 18. Two sets of fixing screw holes 20 are provided on the fixed block 14, the first slider 15, and the second slider 17. The fixing bolt 19 is matched with the fixing screw holes 20.

[0060] Among them, two groups of fixing screw holes 20 on the fixed block 14, the first slider 15 and the second slider 17 are symmetrically arranged up and down, and the fixing bolts 19 can be screwed into the two groups of fixing screw holes 20 respectively to fix the fixing plate 18.

[0061] Specifically, when lifting the water temperature cable upwards, the fixing bolts 19 on the fixing plate 18 are screwed into the upper fixing screw holes 20. At this time, the clamp 16 moves upwards to hold the cable tightly and moves downwards to release the cable, which is used to lift the cable. When lowering the water temperature cable, the fixing bolts 19 are unscrewed, and the clamp 16 and the fixing plate 18 are rotated downwards so that the clamp 16 and the fixing plate 18 rotate 180°. Then, the fixing bolts 19 on the fixing plate 18 are screwed into the lower fixing screw holes 20. After the clamps 16 on the fixed block 14, the first slider 15 and the second slider 17 all complete a 180° rotation and are fixed, at this time, the clamp 16 moves upwards to release the cable and moves downwards to hold the cable tightly, which is used to lower the cable. In this way, the usage method is more diverse, which can not only help lift the cable, but also help lower the cable.

[0062] When in use, the device is installed on the casing at the wellhead of the seismic fluid observation well through the hoop 1. Then, the cable to be lifted is sequentially placed into the clamps 16 on the fixed block 14, the first slider 15 and the second slider 17, and the remaining cable is clamped and fixed inside the snap ring 8 so that the remaining cable is close to the edge.

[0063] Next, the first slider 15 is manually controlled to reciprocate vertically up and down on the guide rail 5 through the rocker arm assembly 10. The clamp 16 on the first slider 15 will vertically lift the cable, so as to manually operate to lift the cable. At the same time, the robotic arm 11 is started, and the robotic arm 11 drives the second slider 17 to reciprocate vertically up and down on the guide rail 5. The clamp 16 on the second slider 17 will also vertically lift the cable, so as to assist the manual operation to lift the cable.

[0064] Lifting force of the cable: F = F1 + F2, where F1 is the pulling force of the human, F2 is the pulling force provided by the machine, F = Mg - Fo, Mg is the gravity of the cable, which will change dynamically during the lifting and lowering process; Fo is the buoyancy of the cable and the probe in water, which is related to the water depth of the cable. In the actual operation process, it only needs to satisfy that the total value of the lifting force of the manual operation plus the machine assistance is not less than Mg - Fo.

[0065] Through the machine assistance mechanism capable of automatically adjusting the lifting force, the present invention can assist during the process of manually operating to lift or lower the water temperature cable by humans, making the lifting and lowering of the water temperature probe safe, time-saving and labor-saving. Moreover, the position of the water temperature cable during the lifting process can be flexibly adjusted, which is convenient for operation. At the same time, other cables can be fixed to avoid winding, which brings great convenience to the lifting and lowering of the water temperature cable.

[0066] The foregoing description of specific exemplary embodiments of the present invention is for purposes of illustration and exemplification. These descriptions are not intended to limit the invention to the precise forms disclosed, and it is apparent that, according to the above teachings, many changes and variations are possible.
