Description

Technical Field

[0001] The present invention relates to the technical field of geophysical exploration, and more specifically, it relates to an automatic wire winding and unwinding device for geophysical exploration. Background Art

[0002] In geophysical exploration operations, the automatic wire winding and unwinding device is an indispensable and important piece of equipment, and its performance directly affects the efficiency and quality of exploration work. However, the current automatic wire winding and unwinding devices on the market face many problems that need to be solved urgently in practical applications.

[0003] Geophysical exploration work often needs to be carried out in complex underground environments, where the conditions of the well walls are uneven and there are a large number of protruding parts. Traditional wire winding and unwinding devices lack effective well wall treatment measures. During the wire winding and unwinding process, the wire harness is extremely likely to come into contact with and rub against the protruding parts of the well wall. Prolonged friction will not only cause the outer insulation layer of the wire harness to be damaged, exposing the internal circuit, affecting the stability and accuracy of signal transmission, but also may cause the wire harness to break, interrupting the exploration work and resulting in double losses of time and economy. For example, in a geological exploration project in the mountains, the wire harness was worn by the protruding parts of the well wall, resulting in distorted exploration data and having to rewire for exploration, greatly delaying the project progress. At the same time, when the wire harness is damaged, traditional wire winding and unwinding devices cannot effectively distinguish and process the damaged parts. It is difficult for workers to quickly locate the damaged position and can only check section by section, consuming a lot of time and energy. Moreover, the damaged parts and the intact parts are wound together, which will exacerbate the damage situation and even affect other intact wire harnesses, increasing the difficulty and cost of maintenance. In large-scale exploration projects, due to the inability to distinguish the damaged parts of the wire harness, maintenance personnel need to check the entire roll of wire harness, greatly reducing the maintenance efficiency and delaying the progress of exploration work.

[0004] In summary, the existing automatic wire winding and unwinding devices for geophysical exploration have obvious deficiencies in aspects such as well wall treatment and damaged part treatment, and it is difficult to meet the increasingly complex exploration operation requirements. Therefore, it is extremely urgent to develop an automatic wire winding and unwinding device that can effectively solve the above problems, ensure the safety of the wire harness, and improve exploration efficiency.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. In the present invention, the protruding part of the wellbore is cut by the annular cutting tool. When the thickness value of the protruding part of the wellbore is less than or equal to the protruding length value of the cutting edge part of the annular cutting tool, the protruding part of the wellbore is cut by the rotation of the annular cutting tool.

When the wire harness passes through the nozzle, the automatic control valve in the pipeline connected to the nozzle is opened, and the water in the water tank is sprayed out through the nozzle to comprehensively wash the wire harness, further removing the stains and soil particles that the bristles failed to clean thoroughly, so that the wire harness is cleaner. After the wire harness is washed, there is residual water on the surface. The wiping cotton contacts the surface of the wire harness to wipe off this residual water, ensuring that the wire harness entering the winding wheel is relatively dry, and avoiding corrosion of the wire harness due to residual water or affecting the subsequent winding quality.

[0040] 4.

During the rotation of the winding wheel, the wire harness is stuck between two adjacent isolation rods, and the damaged part is located on the side of the isolation rod away from the winding wheel. When the wire guiding wheel drives the wire harness to move back, the wire harness is wound around the winding wheel again through the gap between two adjacent isolation rods. Finally, the damaged part and the intact part of the wire harness are wound separately, which is convenient for the staff to repair the damaged part of the wire harness subsequently.

[0059] The annular protection plate 5 is arranged on the wire take-up frame 1. The annular protection plate 5 is located at the end of the wire harness cleaning mechanism. A pulley 6 is rotatably connected to the annular protection plate 5. The pulley 6 cooperates with the wire harness.

[0060] The fixing mechanism is arranged on the annular protection plate 5, and the fixing mechanism is used to fix the position of the annular protection plate 5.

[0061] A first servo motor 7 is fixedly connected to the side wall of the wire take-up frame 1. The output shaft of the first servo motor 7 is fixedly connected to the end of the rotating shaft 3.

And the preset moving length value of the connecting rod 11 is equal to the length value of the winding wheel 2. That is, when the moving position of the connecting rod 11 approaches the end of the winding wheel 2, the second servo motor 10 drives the lead screw 8 to rotate in the reverse direction, thereby driving the connecting rod 11 to move back. Among them, the wire harness detector 4 is signal-connected to the second servo motor 10. When the wire harness detector 4 detects that the wire harness is damaged, the wire harness detector 4 transmits the information to the second servo motor 10.

The limiting block 37 is located in the annular groove 36, and the limiting block 37 is slidably connected to the annular cutting tool 34.

[0082] Working principle: Wind the wire harness to be used around the take-up wheel 2. The wire harness winds around the guide wheel 12, the fixed cylinder 18, and the pulley 6, and then fix the equipment for geophysical exploration in the prior art at the end of the wire harness. When it is necessary to pay out the wire harness for geophysical exploration, start the first servo motor 7. The output shaft of the first servo motor 7 drives the rotating shaft 3 to rotate, and then drives the take-up wheel 2 fixed on the rotating shaft 3 to rotate synchronously, so as to realize the payout of the wire harness. During the payout process of the wire harness, the annular protection plate 5 moves along with the movement of the end of the wire harness. When the end of the wire harness extends into the exploration well and the fixing plate 25 contacts the protruding part of the well wall, start the third servo motor 29. The output shaft of the third servo motor 29 drives the gear 30 to rotate, and meshes with and drives the outer tooth ring 26 and the inner tooth ring 33 to rotate. During the rotation of the inner tooth ring 33, it drives the annular cutting tool 34 to rotate. During the rotation of the annular cutting tool 34, the annular cutting tool 34 cuts the protruding part of the well wall. When the thickness value of the protruding part of the well wall is less than or equal to the protruding length value of the cutting edge part of the annular cutting tool 34, the protruding part of the well wall is cut by the rotation of the annular cutting tool 34. At the same time, during the cutting process of the annular cutting tool 34, the grinding plate on the outer wall of the annular cutting tool 34 grinds the cutting part, so as to avoid the wire harness contacting the protruding part of the well wall and generating friction, and avoid damage to the wire harness. When the thickness value of the protruding part of the well wall is greater than the protruding length value of the cutting edge part of the annular cutting tool 34, the annular cutting tool 34 cuts the protruding part of the well wall during rotation and forms an arc groove. When the upper surface of the protruding part of the well wall contacts the lower surface of the annular protection plate 5, the cutting edge part of the annular cutting tool 34 is stuck in the arc groove cut in the protruding part of the well wall, so as to facilitate clamping and fixing the position of the annular protection plate 5. During the continuous payout of the wire harness, due to the support of the pulley 6 and the fixed rod 24 for the wire harness, it can avoid the wire harness generating friction with the protruding part of the well wall during the payout process and being damaged. When the lowermost annular protection plate 5, that is, the annular protection plate 5 close to the end of the wire harness, contacts the uppermost protruding part of the well wall during the downward movement of the wire harness, due to the cutting of the protruding part of the well wall by the annular cutting tool 34 and the gravity of the annular protection plate 5 and the upper annular protection plate 5 above it, the cut protruding part of the well wall is pressed downward, so that the protruding part of the annular protection plate 5 breaks, achieving the purpose of cutting the protruding part of the well wall.

[0083] When the annular protection plate 5 located at the uppermost upper side contacts the protruding part on the uppermost side of the wellbore, and the length value of the protruding part of the wellbore is greater than or equal to the length value of the fixing plate 25, during the process that the output shaft of the third servo motor 29 drives the gear 30 to rotate and meshes to drive the outer tooth ring 26 and the inner tooth ring 33 to rotate, the outer tooth ring 26 meshes to drive the driving blade 28 to rotate, thereby driving the fixing screw 27 to rotate. During the rotation of the fixing screw 27, the tip part of it screws into the protruding part of the wellbore, so as to fix the position of the annular protection plate 5 through the fixing screw 27, thereby supporting the wire harness through the first annular protection plate 5, avoiding the wire harness from contacting and rubbing against the protruding part of the wellbore, and also avoiding the damage of the wire harness.

[0084] When it is necessary to wind up the wire harness, start the third servo motor 29. The third servo motor 29 drives the outer tooth ring 26 to rotate in the reverse direction through the gear 30. The outer tooth ring 26 meshes to drive the driving blade 28 and the fixing screw 27 to rotate in the reverse direction, so that the tip part of the fixing screw 27 is screwed out of the protruding part of the wellbore. When the upper end of the exploration instrument at the lower end of the wire harness contacts the lowermost annular protection plate 5, during the process that the wire harness pulls the exploration instrument at its lower end upward, it drives the annular protection plate 5 to move upward, thus facilitating the recovery of the annular protection plate 5. Among them, symmetrically arranged ropes are fixedly connected to the lowermost annular protection plate 5. The upper ends of the ropes pass through the upper annular protection plate 5 and are wound around the end of the rotating shaft 3, facilitating the downward movement of the annular protection plate 5 as the wire harness is deployed. At the same time, during the process that the ropes pull the lowermost annular protection plate 5 upward, the annular protection plate 5 drives the upper annular protection plate 5 above it to move upward, thus facilitating the recovery of the annular protection plate 5.

[0085] Since in the field operation environment of geophysical exploration, a large amount of dirt such as mud usually adheres to the surface of the wire harness. Before the wire harness is wound up, it first enters the fixed cylinder 18. The brush hairs 20, through direct contact with the surface of the wire harness, initially clean off this adhered mud. When the wire harness passes through the nozzle 21, the automatic control valve in the pipeline connected to the nozzle 21 opens, and the water in the water tank 22 is sprayed out through the nozzle 21 to conduct a comprehensive flushing of the wire harness, further removing the dirt and soil particles that the brush hairs 20 failed to clean thoroughly, so that the wire harness is cleaner. After the wire harness is flushed, there is residual water on its surface. The wiping cotton 23 wipes off this residual water through contact with the surface of the wire harness, ensuring that the wire harness entering the winding wheel 2 is relatively dry, avoiding corrosion of the wire harness caused by residual water or affecting the subsequent winding quality.

[0086] The wire harness detector 4 is fixed on the wire take-up reel 1 and is located between the wire harness cleaning mechanism and the winding wheel 2. If the wire harness detector 4 uses a monitoring camera, the camera continuously captures the surface of the passing wire harness. When the monitoring camera detects damage such as wear or cracks on the surface of the wire harness, it is determined that the wire harness surface is damaged. If an inductor is used, it judges whether there is damage to the wire harness by sensing changes in the physical properties of the wire harness surface, such as conductivity, magnetic field, etc.

[0087] Start the second servo motor 10. Its output shaft drives the lead screw 8 to rotate. The end of the lead screw 8 is rotatably connected to the support plate 9. The connecting rod 11 is threadedly connected to the lead screw 8, and its lower end is rotatably connected to a wire guide wheel 12. At the same time, the connecting rod 11 is also slidably connected to the limiting rod 13. Due to the rotation of the lead screw 8, the connecting rod 11 makes a reciprocating linear motion along the lead screw 8 and the limiting rod 13 under the restriction of screw thread transmission and the limiting rod 13, thereby driving the wire guide wheel 12 to move back and forth. The preset moving length value of the connecting rod 11 is equal to the length value of the winding wheel 2. When the connecting rod 11 moves to the end close to the winding wheel 2, the second servo motor 10 drives the lead screw 8 to rotate in the reverse direction, causing the connecting rod 11 to move back. In this way, the cycle is repeated to ensure that the wire harness can be evenly wound on the winding wheel 2.

[0088] When the wire harness detector 4 detects that the wire harness is damaged, the wire harness detector 4 transmits the information to the second servo motor 10. After receiving the signal, the second servo motor 10 drives the connecting rod 11 and the wire guide wheel 12 to move to one side of the isolation rod 15 through the lead screw 8, so that the damaged part of the wire harness also moves to one side of the isolation rod 15. During the rotation of the winding wheel 2, the wire harness is stuck between two adjacent isolation rods 15, and the damaged part is located on the side of the isolation rod 15 away from the winding wheel 2. When the wire guide wheel 12 drives the wire harness to move back, the wire harness is wound on the winding wheel 2 again through the gap between two adjacent isolation rods 15. Finally, the damaged part and the intact part of the wire harness are separated and wound, which is convenient for the staff to repair the damaged part of the wire harness later.

[0089] When the staff repairs the damaged wire harness on one side of the isolation rod 15, the staff rotates the bolt and screws out the bolt from the annular plate 14, then removes the support rod 17, and pushes the annular plate 14 towards the end of the winding wheel 2, so that the wire harness passing around the isolation rod 15 becomes loose, which is convenient for the staff to repair the damaged part of the wire harness and brings convenience to the staff.
