Description

Technical Field

[0001] The present application relates to the technical field of wind noise reduction devices, and more specifically, to a wind noise reduction device for magnetotelluric magnetic track reception. Background Art

[0002] Magnetotellurics (including audio magnetotellurics, broadband magnetotellurics, and long-period magnetotellurics) is one of the geophysical methods for detecting the depth from the near surface to the upper mantle; due to its sensitivity to low-resistivity bodies, it plays an important role in deep structure detection, earthquake gestation environment, geodynamics, and geothermal and resource exploration.

[0003] In the related art, during the operation of magnetotellurics, the connection line between the detection end and the receiving end needs to be arranged and fixed to prevent the wire harness from shaking due to external wind noise and cutting the magnetic field lines; in order to facilitate fixing the wire harness during wiring, for example, the patent with the publication number CN111897016B in the prior art provides a wind noise reduction device for a magnetotelluric magnetic track receiver. This device passes the wire through the wire passing port and rotates the pre-tightening part II to press against the wire, and then adjusts the height of the wire clamping part until the wire is in a taut state, which can avoid cutting the magnetic field lines during shaking and avoid generating induced current; the grooving part can move in multiple degrees of freedom for grooving, which is convenient for deep burying of the probe; and a carbon fiber adaptation base frame and a waterproof rubber cloth are used to shade, moisture-proof and reduce wind noise during field data collection.

[0004] Although the above prior art solution can achieve the effect of positioning and tightening the wire harness through the pre-tightening part and the height-adjustable wire clamping part, the wire clamping part will cause an upward pulling force on the wire harness during the height adjustment process, resulting in a certain pulling force of the wire harness on the deeply buried probe. When the wire harness is tightened, the continuous pulling force may drive the probe to loosen and lose the wind noise reduction effect; it may also damage the effective connection between the wire harness and the probe, and the use is not safe enough.

[0005] In view of this, we propose a wind noise reduction device for magnetotelluric magnetic track reception. Summary of the Invention

[0006] The purpose of the present application is to provide a wind noise reduction device for magnetotelluric magnetic track reception, which solves the technical problem that the probe wire harness is not safe enough after being tightened and fixed, and realizes the technical effect of safely fixing the probe wire harness.

[0007] The present application provides a wind noise reduction device for magnetotelluric magnetic track reception, including:

[0008] A fence for reducing wind noise, with a movable frame movably arranged at the top of the fence;

[0009] A rotating member rotatably arranged inside the movable frame, with an instrument rack fixedly arranged at the bottom of the rotating member;

[0010] A grooving tool, which is used to assist in grooving, and the grooving tool is rotatably arranged on one side of a rotating member;

[0011] A wire bundling post, which is used to press the wire harness, and the wire bundling post slides vertically on the other side of the rotating member;

[0012] A tightening ring, which is used to tighten the wire harness, and the tightening ring is rotatably arranged at the bottom of the rotating member, and the tightening ring is located below the wire bundling post;

[0013] A motor, which is used to synchronously drive the grooving tool and the tightening ring to rotate, and the motor is fixedly arranged on the top of the rotating member;

[0015] By adopting the above technical solution, start the motor to drive the grooving tool to rotate for grooving. During the grooving process, drive the grooving tool to move downward through the electric push rod to facilitate the adjustment of the grooving depth. After the grooving is completed, the electric push rod drives the grooving tool to reset upward. Rotate the rotating member inside the moving frame by 180°, so that the grooving tool and the tightening ring are located at the top of the moving frame. Then drive the wire bundling post to move downward through the electric push rod, so that the end of the wire bundling post abuts against the ground to press the wire harness. At this time, the grooving tool moves upward away from the inside of the enclosure. Then arrange the wire harness upward along the outside of the wire bundling post, and pass the other end through the tightening ring and connect it to the detector. Finally, start the motor to drive the tightening ring to rotate, so that the tightening ring drives the wire harness outside the wire bundling post to twist and tighten. At this time, the other end of the wire harness is pressed against the ground by the wire bundling post, which will not affect the buried probe and the connection between the two, making the reinforcement of the wire harness safer.

[0025] The connecting plate is fixedly connected to the driving end of the electric push rod, and the connecting plate is rotatably arranged at the top of the flower shaft.

[0026] By adopting the above technical solution, when the motor drives the Gear B to rotate, it drives the Gear C to rotate, so that the Gear C drives the inner flower shaft to rotate, and the flower shaft drives the groover to rotate and groove. At this time, the electric push rod drives the connecting plate to move downward, so that the connecting plate pushes the flower shaft to slide downward inside the Gear C, and the flower shaft pushes the groover to move downward for depth adjustment to meet the grooving conditions.

[0027] As an alternative solution of the technical solution of this application document, it further includes:

[0028] The bearing plate is fixedly arranged at the bottom of the rotating member;

[0029] The connecting shaft is coaxially and fixedly arranged at the driving end of the motor. The other end of the connecting shaft is fixedly provided with a Gear D, and the Gear D is rotatably connected to the bearing plate;

[0030] Gear A is fixedly arranged outside the tightening ring. The Gear A is meshed and connected outside the Gear D, and the Gear A is rotatably connected to the bearing plate.

[0031] By adopting the above technical solution, when the motor drives the Gear B to rotate, it drives the Gear D to rotate through the connecting shaft. The Gear D drives the tightening ring to rotate through the Gear A, so that the tightening ring rotates idly during the grooving process and performs a rotating tightening action when arranging the wire harness.

[0032] As an alternative solution of the technical solution of this application document, it further includes:

[0033] The toothed plate A is fixedly arranged at the end of the connecting plate. The toothed plate A is slidably arranged outside the support plate, and the support plate is fixedly arranged outside the rotating member;

[0034] Gear E is rotatably arranged outside the support plate. The Gear E is meshed and arranged outside the toothed plate A;

[0035] The toothed plate B is fixedly arranged outside the wire harness column. The toothed plate B is meshed and arranged outside the Gear E, and the toothed plate B is slidably connected to the support plate.

[0036] By adopting the above technical solution, when the connecting plate drives the grooving tool to move downward, the connecting plate drives the toothed plate A to slide downward on the outside of the gear E. At this time, the gear E rotates to drive the toothed plate B on the other side to rotate upward, realizing the reverse movement of the driving wire bundling column and the grooving tool, and the structure is simple and convenient for maintenance.

[0037] As an alternative solution of the technical solution of this application document, it further includes:

[0038] The limiting block A is symmetrically and fixedly arranged on the outside of the moving frame. An axial hole A is opened between the limiting blocks A on one side of the moving frame;

[0039] The fixed shaft is fixedly arranged on the other side of the moving frame and is located inside the moving frame corresponding to the axial hole A. The fixed shaft is rotatably arranged on the outside of the rotating part through the axial hole B;

[0040] The handwheel is rotatably arranged on the outside of the moving frame corresponding to the axial hole A. The handwheel is fixedly connected to the rotating part. A limiting block B is fixedly arranged on the outside of the handwheel. The limiting block B cooperates with the limiting block A to limit the rotation range of the handwheel.

[0041] By adopting the above technical solution, after grooving is completed, the rotating part is driven to rotate inside the moving frame by the handwheel. When the limiting block B on the outside of the handwheel rotates to the bottom of the other limiting block A, the rotation stops. At this time, the rotating part realizes a 180° flip, ensuring the stability of the rotating part under the support of the fixed shaft and the handwheel. And under the action of the limiting block A, it only needs to force the limiting block B to closely lean against the limiting block A to ensure that the handwheel cannot rotate when in the card slot or pressing the wire.

[0042] As an alternative solution of the technical solution of this application document, it further includes:

[0043] The convex block is fixedly arranged on one side of the rotating part close to the fixed shaft;

[0044] The wedge-shaped block A is slidably arranged on the outside of the convex block. An anti-slip groove is arranged inside the wedge-shaped block A, and the anti-slip groove is engaged and locked with the anti-slip protrusion on the outside of the fixed shaft;

[0045] The spring is used to provide the reset power for the wedge-shaped block A;

[0046] The wedge-shaped block B is used to squeeze the wedge-shaped block A to approach the convex block. The wedge-shaped block B is slidably arranged on the outside of the wedge-shaped block A. The wedge-shaped block B is fixedly arranged on the outside of the wire bundling column.

[0047] By adopting the above technical solution, when the rotating member flips, it drives the wire bundling column and the wedge block A to rotate synchronously, so that the relative positions of the wedge block B and the wedge block A remain unchanged. As the electric push rod is started to drive the wire bundling column to slide, the wire bundling column drives the wedge block B to slide outside the wedge block A, causing the wedge block B to squeeze the wedge block A towards the convex block. Furthermore, through the cooperation of the anti-slip groove on the inner side and the anti-slip protrusion, the rotating member cannot rotate around the fixed shaft, thereby achieving the effect of quickly fixing the rotating member.

[0048] As an alternative solution of the technical solution of this application document, the wire bundling column includes:

[0049] A wire hole is opened on the inner side of the wire bundling column and is arranged parallel to the axial direction of the wire bundling column. The wire hole is waist-shaped;

[0050] An inlet port is opened on the outer side of the wire bundling column and is located at one end of the wire hole.

[0051] By adopting the above technical solution, the wire harness is hidden inside the wire hole through the inlet port, isolating the wire harness from external wind noise, and then tightened to improve the fixing effect on the wire harness.

[0052] As an alternative solution of the technical solution of this application document, the wire bundling column further includes a wire pressing groove located at the pressing end. The wire pressing groove is opened at the other end of the wire hole and is used to press the wire harness at the bottom.

[0053] By adopting the above technical solution, when pressing the wire, place the wire harness inside the wire pressing groove, and the other end is placed inside the wire hole through the inlet port, and the wire harness is pressed through the wire pressing groove.

[0054] As an alternative solution of the technical solution of this application document, a wire buckle is fixedly arranged inside the tightening ring, and the wire buckle rotates in the direction away from the inlet port of the wire hole.

[0055] By adopting the above technical solution, when the wire harness passes through the inside of the wire hole and then passes through the inside of the tightening ring, then hang the wire harness inside the wire buckle. When the motor drives the tightening ring to rotate, it drives the wire buckle to rotate to the side of the wire hole away from the inlet port, causing the wire buckle to drive the wire harness to tighten towards the inside of the wire hole, and the other end of the wire harness can be connected to the detector on the top of the connector frame.

[0056] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0057] (1) In this application, since the electric push rod is used to drive the wire bundling column to press the wire harness, and then the motor drives the tightening ring to tighten the pressed wire harness, so that the wire harness will not affect the probe after being tightened. Therefore, it effectively solves the problem that the probe wire harness is not safe enough to use after being tightened and fixed, and further realizes the safe fixing of the probe wire harness and improves the anti-wind noise ability.

[0058] (2) In this application, a motor is fixedly arranged at the top of the rotating part to drive the tightening ring to tighten the wire harness. Before fixing the wire harness, the grooving tool can be driven by the motor to perform grooving work, so as to bury the probe deeply. The two operations complement each other without interference, effectively utilizing the power of the motor.

[0059] (3) In this application, an electric push rod is arranged outside the rotating part to drive the wire bundling column to move. At the same time, the electric push rod drives the grooving tool to move in the opposite direction to the wire bundling column, so that the electric push rod adjusts the depth during the grooving process of the grooving tool, and drives the wire bundling column to move in the opposite direction to the grooving direction, making the grooving work and the wire pressing work complement each other without interference.

[0060] (4) In this application, a rotating part is rotatably arranged inside the moving frame. By rotating the rotating part, the grooving tool and the wire bundling column are driven to change the working state, and there is no need to disassemble and replace them separately, which is more convenient to use.

[0061] (5) In this application, a wedge block B is fixedly arranged outside the wire bundling column. When the wire bundling column rotates driven by the rotating part each time, it will slide driven by the electric push rod, so that the wire bundling column triggers the fixing action of the wedge block A on the rotating part through the wedge block B, facilitating quick reinforcement after the rotating part rotates.

[0080] The present application will be further described in detail below with reference to the accompanying drawings of the specification.

[0081] Refer to Figures 1 - 5The embodiment of the present application discloses an anti-wind noise device for receiving magnetic track of magnetotelluric method, including an enclosure 1 for anti-wind noise, a movable frame 11 is movably arranged on the top of the enclosure 1, a rotating member 2 is rotatably arranged inside the movable frame 11, a slotter 3 is rotatably arranged on one side of the rotating member 2, a cable tie post 4 is slidably arranged on the other side of the rotating member 2, a tightening ring 5 is rotatably arranged at the bottom of the rotating member 2, and the tightening ring 5 is located at the bottom of the cable tie post 4; a motor 6 is fixedly arranged on the top of the rotating member 2, and the motor 6 synchronously drives the slotter 3 and the tightening ring 5 to rotate, an electric push rod 7 for driving the slotter 3 and the cable tie post 4 to slide in opposite directions is fixedly arranged on the outside of the rotating member 2, and an apparatus frame 21 is fixedly arranged at the bottom of the rotating member 2. After the enclosure 1 is placed at the detection position, the moving frame 11 on the top of the enclosure 1 is moved to drive the internal rotating part 2 to move, so that the rotating part 2 drives the slotter 3 on one side to move to the slotting position, and then the motor 6 is started to drive the slotter 3 to rotate for slotting. At this time, the motor 6 synchronously drives the tightening ring 5 to rotate, and the tightening ring 5 does not affect the slotting work of the slotter 3. During the slotting process, the slotter 3 is driven downward by the electric push rod 7 to adjust the slotting depth to ensure that the probe can be buried deeply. At this time, the electric push rod 7 synchronously drives the wire beam column 4 to move upward without affecting the slotting work. When the slotting is completed, the electric push rod 7 drives the slotter 3 to reset upward again. At this time, the wire beam column 4 follows and resets itself downward, and then the inner side of the moving frame 11 The rotating member 2 rotates 180°, so that the slotter 3 and the tightening ring 5 are located at the top of the moving frame 11, and then the electric push rod 7 drives the wiring post 4 to move downward, so that the end of the wiring post 4 is pressed against the ground to compress the wiring harness. At this time, the slotter 3 moves upward away from the inside of the enclosure 1, and then the wiring harness is arranged upward along the outside of the wiring post 4, and the other end is passed through the tightening ring 5 and connected to the detector. Finally, the motor 6 is started to drive the tightening ring 5 to rotate, so that the tightening ring 5 drives the wiring harness on the outside of the wiring post 4 to twist and tighten. At this time, the other end of the wiring harness is pressed on the ground by the wiring post 4, which will not affect the deeply buried probe and the connection between the two, making the wiring harness reinforcement safer and making the arranged wiring harness tightened more convenient under the drive of the motor 6.

[0082] In order to facilitate the movement of the moving frame 11 to drive the slotting device 3 and the cable tie column 4 to the working position, refer to Figure 1, the enclosure 1 is cylindrical, and a slip ring 12 is rotatably arranged at the top of the enclosure 1. At the top of the slip ring 12, slide rails 13 are symmetrically and fixedly arranged parallel to the radial direction. Slide tables 14 are slidably arranged on the inner sides of the slide rails 13. The slide tables 14 are fixedly arranged at the bottom of the moving frame 11. A bolt 15 is threadedly arranged at the top of the slip ring 12 for fixing the slip ring 12 and the enclosure 1. When adjusting the positions of the grooving tool 3 or the wire bundling post 4, by rotating the slide rails 13, the grooving tool 3 or the wire bundling post 4 can be located in different orientations, and then by sliding the moving frame 11, the grooving tool 3 or the wire bundling post 4 can be located at different positions in this orientation. The length of the moving frame 11 satisfies the rotation of the grooving tool 3 and the wire bundling post 4, and the moving frame 11 can slide to the top of the slip ring 12 through the slide rails 13, so that the moving frame 11 can drive the grooving tool 3 to move fully inside the enclosure 1.

[0083] In order to realize that the motor 6 can cooperate with the electric push rod 7 for depth adjustment during the process of driving the grooving tool 3 to groove, refer to Figure 2 , Figure 3 and Figure 6 , a gear B61 is fixedly arranged at the driving end of the motor 6. The gear B61 is rotatably arranged inside the rotating part 2. A gear C62 is meshed on the outside of the gear B61. The gear C62 is rotatably arranged outside the rotating part 2. A spline shaft 63 is slidably arranged along the axial direction on the inside of the gear C62. The spline shaft 63 is fixedly arranged at the top of the grooving tool 3. A connecting plate 71 is rotatably arranged at the top of the spline shaft 63. The connecting plate 71 is fixedly arranged at the driving end of the electric push rod 7. When the motor 6 drives the gear B61 to rotate, it drives the gear C62 to rotate, so that the gear C62 drives the spline shaft 63 inside it to rotate. The spline shaft 63 drives the grooving tool 3 to rotate and groove. At this time, the electric push rod 7 drives the connecting plate 71 to move downward, so that the connecting plate 71 pushes the spline shaft 63 to slide downward inside the gear C62, and the spline shaft 63 pushes the grooving tool 3 to move downward for depth adjustment to meet the grooving conditions.

[0084] In order to realize that the motor 6 can synchronously drive the grooving tool 3 and the tightening ring 5 to rotate after starting, refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 , a gear D64 is fixedly arranged at the driving end of the motor 6 through a connecting shaft 65. A gear A51 is meshed on the outside of the gear D64. The gear A51 is fixedly arranged on the outside of the tightening ring 5. Both the tightening ring 5 and the gear D64 are rotatably arranged inside a bearing plate 29. The bearing plate 29 is fixedly arranged at the bottom of the rotating part 2. When the motor 6 drives the gear B61 to rotate, it drives the gear D64 to rotate through the connecting shaft 65. The gear D64 drives the tightening ring 5 to rotate through the gear A51, so that the tightening ring 5 rotates idly during the grooving process and performs a rotating tightening action when arranging the wire harness.

[0085] To achieve the simultaneous downward movement of the electric push rod 7 driving the grooving tool 3 and the upward reverse movement of the wire bundling column 4, referring to Figure 2 , Figure 3 and Figure 6 , on the other end of the connecting plate 71, a toothed plate A72 is fixedly arranged, a gear E73 is meshed on the outside of the toothed plate A72, the gear E73 is rotatably arranged on the outside of the support plate 210, the support plate 210 is fixedly arranged on the outside of the rotating member 2, a toothed plate B74 is meshed on the other side of the gear E73, and the toothed plate B74 is fixedly arranged on the outside of the wire bundling column 4. When the connecting plate 71 drives the grooving tool 3 to move downward, the connecting plate 71 drives the toothed plate A72 to slide downward on the outside of the gear E73. At this time, the gear E73 rotates to drive the toothed plate B74 on the other side to rotate upward, realizing the reverse movement of the driving wire bundling column 4 and the grooving tool 3, and the structure is simple and convenient for maintenance.

[0086] To facilitate the switching between the two working states of grooving and wire pressing, referring to Figure 2 , Figure 4 , Figure 6 and Figure 8 , a shaft hole A17 is opened on one side of the moving frame 11, the rotating member 2 is rotatably arranged inside the moving frame 11 through the shaft hole A17, a handwheel 22 is fixedly arranged on the outside of the rotating member 2 corresponding to the shaft hole A17, a limiting block B23 is fixedly arranged on the outside of the handwheel 22, and a limiting block A16 is fixedly arranged on the outside of the moving frame 11 corresponding to the limiting block B23, for limiting the rotation range of the limiting block B23 to 0 - 180°; a fixed shaft 18 is fixedly arranged on the other side of the moving frame 11, a shaft hole B24 is opened on one side of the rotating member 2 corresponding to the fixed shaft 18, and the fixed shaft 18 is rotatably arranged inside the shaft hole B24. After grooving is completed, the rotating member 2 is driven to rotate inside the moving frame 11 through the handwheel 22. When the limiting block B23 on the outside of the handwheel 22 rotates to the bottom of the other limiting block A16, the rotation stops. At this time, the rotating member 2 realizes a 180° flip. The stability of the rotating member 2 is ensured by the support of the fixed shaft 18 and the handwheel 22. And under the action of the limiting block A16, only by pressing the limiting block B23 tightly against the limiting block A16 with force can it be ensured that the handwheel 22 cannot rotate during grooving or wire pressing.

[0087] To facilitate fixing the rotating member 2 after flipping to save labor input, referring to Figure 6 , Figure 7 and Figure 8, a convex block 25 is fixedly arranged on the outer side of the rotating member 2, a wedge-shaped block A26 is slidably arranged on the outer side of the convex block 25, a spring 28 is fixedly arranged on the side of the wedge-shaped block A26 away from the wire bundling column 4, and the other end of the spring 28 is fixedly arranged on the outer side of the rotating member 2; an anti-slip groove 27 is arranged on the inner side of the wedge-shaped block A26, and an anti-slip protrusion 19 is arranged on the outer side of the fixed shaft 18 corresponding to the anti-slip groove 27. A wedge-shaped block B41 is slidably arranged on the side of the wedge-shaped block A26 away from the convex block 25, and the wedge-shaped block B41 is fixedly arranged on the outer side of the wire bundling column 4. When the rotating member 2 flips, it drives the wire bundling column 4 and the wedge-shaped block A26 to rotate synchronously, so that the relative positions of the wedge-shaped block B41 and the wedge-shaped block A26 remain unchanged. As the electric push rod 7 is started to drive the wire bundling column 4 to slide, the wire bundling column 4 drives the wedge-shaped block B41 to slide on the outer side of the wedge-shaped block A26, so that the wedge-shaped block B41 squeezes the wedge-shaped block A26 to approach the convex block 25. Then, through the cooperation of the anti-slip groove 27 and the anti-slip protrusion 19 on the inner side, the rotating member 2 cannot rotate around the fixed shaft 18, thus achieving the effect of quickly fixing the rotating member 2.

[0088] In order to realize the protection function of the wire bundling column 4 for the wire harness, referring to Figure 9 and Figure 10 , a waist-shaped wire hole 42 is axially and parallelly opened on the inner side of the wire bundling column 4, an inlet port 43 is opened on the outer side of the wire bundling column 4 corresponding to one end of the wire hole 42, and a wire pressing groove 44 is opened on the end of the wire bundling column 4 for pressing the wire corresponding to the other end of the wire hole 42. When pressing the wire, the wire harness is placed inside the wire pressing groove 44, and the other end is placed inside the wire hole 42 through the inlet port 43. The wire harness is pressed tightly through the wire pressing groove 44. At this time, the wire harness is in a relaxed state inside the wire hole 42. Finally, the wire harness is tightened through the tightening ring 5 at the other end of the wire bundling column 4.

[0089] Referring to Figure 10 , a wire buckle 52 is fixedly arranged on the inner side of the tightening ring 5, and the wire buckle 52 rotates in the direction away from the inlet port 43 of the wire hole 42. When the wire harness passes through the inside of the wire hole 42 and then passes through the inside of the tightening ring 5, and then the wire harness is hung on the inner side of the wire buckle 52. When the motor 6 drives the tightening ring 5 to rotate, it drives the wire buckle 52 to rotate to the side of the wire hole 42 away from the inlet port 43, so that the wire buckle 52 drives the wire harness to tighten towards the inside of the wire hole 42, and the other end of the wire harness can be connected to the detector on the top of the connector frame 21.

[0090] In summary, when the wind noise resistant device for magnetotelluric method magnetic track reception disclosed in the embodiments of the present application is in use, the enclosure 1 is placed at the detection position for wind noise prevention. By rotating the sliding rail 13, the grooving tool 3 is located at the required azimuth. Then, by sliding the moving frame 11, the grooving tool 3 is located at the grooving position of this azimuth. Then, when the motor 6 is started to drive the gear B61 to rotate, the gear C62 is driven to rotate, so that the gear C62 drives the inner flower shaft 63 to rotate, and the flower shaft 63 drives the grooving tool 3 to rotate and groove. At this time, the electric push rod 7 drives the connecting plate 71 to move downward, so that the connecting plate 71 pushes the flower shaft 63 to slide downward inside the gear C62, and the flower shaft 63 pushes the grooving tool 3 to move downward for depth adjustment. And when the connecting plate 71 drives the grooving tool 3 to move downward, the connecting plate 71 drives the tooth plate A72 to slide downward outside the gear E73. At this time, the gear E73 rotates to drive the other tooth plate B74 to rotate upward, realizing the reverse movement of the wire beam column 4 and the grooving tool 3. And the wire beam column 4 drives the wedge block B41 to slide outside the wedge block A26, so that the wedge block B41 squeezes the wedge block A26 to approach the convex block 25. Then, through the cooperation of the anti-slip groove 27 inside and the anti-slip protrusion 19, the rotating part 2 cannot rotate around the fixed shaft 18, thereby realizing the effect of quickly fixing the rotating part 2 to ensure the stability of the rotating part 2 during the grooving process;

[0091] When the grooving is completed, the electric push rod 7 runs in the reverse direction to drive the grooving tool 3 and the wire beam column 4 to reset. At this time, the wire beam column 4 drives the wedge block B41 to release the extrusion of the wedge block A26, and the wedge block A26 automatically resets away from the convex block 25 under the action of the spring 28, so that the anti-slip groove 27 releases the locking of the anti-slip protrusion 19, and the rotating part 2 can rotate. Then, the handwheel 22 drives the rotating part 2 to rotate inside the moving frame 11. When the limiting block B23 on the outer side of the handwheel 22 turns to the bottom of another limiting block A16, the rotation stops. At this time, the rotating part 2 realizes a 180° flip. Then, the electric push rod 7 is used to drive the wire beam column 4 to move downward, so that the wire beam column 4 drives the wedge block B41 to squeeze the wedge block A26 to fix the rotating part 2 again. When the wire pressing end of the wire beam column 4 is about to approach the ground, the wire harness is placed inside the wire pressing groove 44, and the other end is placed inside the wire hole 42 through the wire inlet 43. The wire harness is pressed tightly through the wire pressing groove 44. At this time, the wire harness is in a relaxed state inside the wire hole 42. Then, the wire harness is hung inside the wire buckle 52. When the motor 6 drives the tightening ring 5 to rotate, it drives the wire buckle 52 to rotate toward the side of the wire hole 42 away from the wire inlet 43, so that the wire buckle 52 drives the wire harness to tighten inside the wire hole 42. And the other end of the wire harness can be connected to the detector on the top of the connector frame 21 to complete the fixed connection of the wire harness.
