The receiving device 5 is composed of hinged arc components and can flexibly adapt to power transmission ground wires of different shapes and sizes to ensure the comprehensiveness and accuracy of the detection. By receiving and analyzing the propagation characteristics of elastic waves in the power transmission ground wire, hidden damage can be accurately identified, providing strong protection for the safe operation of the power transmission ground wire. The setting of the reinforcement tube 6 enhances the stability of the receiving device 5, and can maintain a stable receiving state even under complex environmental conditions, thereby improving the reliability of the detection results.

[0036] In a further preferred embodiment of the present invention, the driving mechanism includes: a mounting frame 7 fixedly mounted on the bottom of the inner wall of the box body 1, the mounting frame 7 is located above the bidirectional screw 2, and a connecting port is opened on the top of the mounting frame 7; a motor 8 and a mounting plate fixedly mounted on the top of the mounting frame 7; a group of driving gears 9 respectively mounted on the mounting plate and the bidirectional screw 2, the driving gear 9 located on the mounting plate is fixedly connected to the output shaft of the motor 8 and meshes with a group of the driving gears 9, and a group of the driving gears 9 are all in rotational contact with the connecting port.

[0037] In this embodiment, when the receiving device 5 is installed on the ground wire, the motor 8 is first started so that the output shaft of the motor 8 drives the active gear 9 to rotate, and the active gear 9 rotates to drive another active gear 9 to rotate, so that the active gear 9 drives the bidirectional screw 2 to rotate, and the bidirectional screw 2 rotates to drive the slider 3 to slide, thereby achieving the fixation and adjustment of the receiving device 5. The power is transmitted by the meshing method of the active gear 9, which has the advantages of high transmission efficiency, accurate transmission ratio, and smooth operation. It helps to ensure that the bidirectional screw 2 can rotate stably and accurately, thereby achieving precise fixation and adjustment of the receiving device 5. Since the structure of the driving mechanism is relatively simple and modularly designed, it is more convenient and quick to maintain and replace parts, which reduces the maintenance cost and time cost of the equipment.

[0038] In a further preferred embodiment of the present invention, a support plate 11 is fixedly installed on the top of the mounting frame 7, a threaded rod 12 is rotatably installed on the support plate 11, the threaded rod 12 is threadedly connected to the reinforcement tube 6, a buffer pad 13 is installed on the top of the reinforcement tube 6, the buffer pad 13 is in sliding contact with the bottom of the receiving device 5, and a bevel gear 14 is fixedly sleeved on the threaded rod 12 and the bidirectional screw rod 2, and a group of the bevel gears 14 are meshed with each other.

[0039] In this embodiment, while the bidirectional screw 2 rotates, it synchronously drives the bevel gear 14 to rotate, so that the bevel gear 14 drives the threaded rod 12 to rotate, and the threaded rod 12 rotates to drive the reinforcement tube 6 to slide up, so that the reinforcement tube 6 slides up and contacts the shell of the receiving device 5, so that the receiving device 5 fits tightly on the power transmission ground wire, which is conducive to receiving the elastic wave signal emitted by the excitation device. When the reinforcement tube 6 is close to the receiving device 5, the buffer pad 13 protects the reinforcement tube 6 and the receiving device 5, thereby ensuring that the reinforcement tube 6 will not crush the receiving device 5. By rotating the bidirectional screw 2 and utilizing the transmission effect of the bevel gear 14, the reinforcement tube 6 can be easily adjusted. Height, thereby achieving precise positioning and reinforcement of the receiving device 5. This height-adjustable design enables the receiving device 5 to adapt to different working environments and needs. The buffer pad 13 at the top of the reinforcement tube 6 provides effective buffering protection for the receiving device 5, reduces the impact of external shocks and vibrations on the equipment, and extends the service life of the equipment. The fixed installation of the support plate 11 and the threaded connection between the threaded rod 12 and the reinforcement tube 6 ensure the stability of the entire adjustment mechanism, so that the receiving device 5 can remain stable and not shake during operation. The lifting and lowering adjustment of the reinforcement tube 6 can be achieved by rotating the bidirectional screw 2. The operation is simple and quick, and the work efficiency is improved.

[0040] In a further preferred embodiment of the present invention, a guide rod 15 is fixedly mounted on the support plate 11 , a guide block 16 is slidably mounted on the guide rod 15 , and the guide block 16 is fixedly connected to the reinforcement tube 6 .

[0041] In this embodiment, the reinforcement cylinder 6 drives the guide block 16 to move while sliding, so that the guide block 16 slides along the guide rod 15, so that the guide rod 15 guides the reinforcement cylinder 6 to ensure that the reinforcement cylinder 6 slides smoothly. Through the coordinated use of the guide rod 15 and the guide block 16, a stable linear motion track is provided for the reinforcement cylinder 6, which helps to maintain the stability and accuracy of the reinforcement cylinder 6 when the receiving device 5 is fixed and adjusted, and prevents it from shifting or shaking, thereby improving the accuracy of the detection results. Due to the guiding effect of the guide rod 15 and the guide block 16, the movement and positioning of the reinforcement cylinder 6 are more precise, thereby ensuring that the receiving device 5 can accurately fit on the power transmission ground wire, further improving the reliability and accuracy of the detection.

[0042] In a further preferred embodiment of the present invention, a mounting block 17 is fixedly installed on one end of the connecting rod 4, a connecting block 18 is installed on one side of the receiving device 5, the connecting block 18 is in contact with the mounting block 17, a connecting bolt 19 is threadedly installed on the mounting block 17, and the connecting bolt 19 is threadedly connected to the connecting block 18.

[0043] In this embodiment, when the receiving device 5 needs to be replaced or repaired, the connecting bolt 19 is first removed from the mounting block 17, and then the connecting block 18 is taken out, so that the receiving device 5 can be repaired or replaced. The operation is relatively quick. Through the coordinated use of the mounting block 17, the connecting block 18 and the connecting bolt 19, the connection between the connecting rod 4 and the receiving device 5 is more firm and reliable. This connection method can withstand greater tension and shear force, ensuring that the receiving device 5 will not loosen or fall off due to external force during the detection process. The threaded connection method of the connecting bolt 19 makes the installation and disassembly process simple and quick. When the receiving device 5 needs to be installed, it is only necessary to place the connecting block 18 on the mounting block 17 and then tighten the connecting bolt 19. Similarly, when disassembly is required, it is only necessary to loosen the connecting bolt 19 to separate the receiving device 5 from the connecting rod 4.

[0044] In a further preferred embodiment of the present invention, a counterweight base 20 is fixedly installed on the bottom of the box body 1, a connecting plate 21 is provided on one side of the counterweight base 20, a mounting groove is opened on one side of the connecting plate 21, a power storage device 23 is installed in the mounting groove, and the power storage device 23 is connected to the motor 8 by wires.

[0045] In this embodiment, during operation, the power storage device 23 converts the stored electrical energy into electric current through the internal chemical reaction, and transmits it to the receiving device 5, the motor 8 and the electric telescopic rod 35 on the box body 1 through the circuit system. After receiving the electrical energy, these electrical devices begin to perform their respective functions (such as the rotation of the motor 8 and the operation of the receiving device 5, etc.), thereby completing the flaw detection task of the power transmission ground wire. At the same time, the setting of the counterweight base 20 makes the device more stable when placed or working, reducing the risk of displacement or tipping due to vibration or external force. The setting of the counterweight base 20 significantly improves the overall weight and Stability reduces shaking and deviation caused by external environmental factors (such as wind, vibration, etc.), thereby improving the accuracy and reliability of the test results. The stable device structure reduces the safety hazards caused by shaking or falling off, and ensures the safety of test personnel and equipment. Although the counterweight base 20 increases the weight of the device, its structure is compact and the design is reasonable, so that the entire receiving device still maintains a high degree of convenience during carrying and installation. The addition of the power storage device 23 provides a reliable power supply for the motor 8 and the receiving device 5, so that the receiving device can operate for a long time without an external power supply, extending the battery life and scope of use of the device.

[0046] In a further preferred embodiment of the present invention, a trapezoidal groove is provided on one side of the counterweight base 20, a trapezoidal rod 22 is fixedly installed on one side of the connecting plate 21, the trapezoidal rod 22 is slidably connected to the trapezoidal groove, and an arc frame 30 is rotatably installed on one side of the counterweight base 20, and the fan-shaped block of the arc frame 30 is in rotational contact with one end of the trapezoidal rod 22.

[0047] In this embodiment, when the power storage device 23 needs to be charged, the arc frame 30 is first rotated to rotate the fan-shaped block of the arc frame 30 away from the trapezoidal rod 22, and then the L-shaped handle is held to pull the connecting plate 21, so that the connecting plate 21 drives the trapezoidal rod 22 to slide away from the trapezoidal groove, so that the connecting plate 21 is separated from the counterweight base 20, and then the connecting plate 21 can be placed in the charging area to charge the power storage device 23. Through the sliding connection design of the trapezoidal groove and the trapezoidal rod 22, and the rotation support of the trapezoidal rod 22 by the arc frame 30, the connecting plate 21 can be installed on the counterweight base 20 more quickly, and the installation is faster.

[0048] In a further preferred embodiment of the present invention, a connecting rod 24 is fixedly installed on one side of the connecting plate 21, and a connecting block 25 and a reset spring 26 are slidably sleeved on the connecting rod 24, one side of the connecting block 25 is in contact with one end of the reset spring 26, and a limiting plate 27 is fixedly installed on the connecting block 25, and the limiting plate 27 is in sliding contact with the notch of the mounting groove.

[0049] In this embodiment, when the device is not in use, first remove the wires connected to the power storage device 23 and place it in the box 1, then slide the limit plate 27 on the notch of the installation slot to seal the notch, thereby ensuring that external impurities and dust do not enter the installation slot, which is beneficial to the protection of the power storage device 23;

[0050] When the wire needs to be connected to the power storage device 23, first slide the limit plate 27 so that the limit plate 27 drives the connecting block 25 to slide, and the connecting block 25 slides along the connecting rod 24. While the connecting block 25 slides, the reset spring 26 is compressed, so that the limit plate 27 slides away from the installation slot to expose the installation slot. After that, the wire can be inserted into the socket of the power storage device 23. Through the design of the sliding connecting block 25 and the limit plate 27, the operator can quickly open and close the notch of the installation slot, thereby simplifying the installation and disassembly process of the power storage device 23. This not only improves work efficiency, but also reduces operation difficulty and time cost. The sliding contact design between the limit plate 27 and the notch of the installation slot can effectively reduce external dust and impurities from entering the installation slot.

[0051] In a further preferred embodiment of the present invention, a screw rod 28 is threadedly mounted on the limit plate 27 , a pressure block is mounted on one end of the screw rod 28 , and the pressure block is in rotational contact with a blocking piece of the connecting rod 24 .

[0052] In this embodiment, when it is necessary to fix the power storage device 23, the operator first opens the notch of the installation slot by sliding the connecting block 25 and the limiting plate 27, and places the power storage device 23 into the slot. When the limiting plate 27 slides away from the installation slot, the screw rod 28 is rotated to move inward along the thread direction, and the pressure block is pushed to press the baffle on the connecting rod 24 to fix the limiting plate 27, thereby facilitating the installation of the power storage device 23. Through the cooperation of the screw rod 28 and the pressure block, the connecting block 25 and the limiting plate 27 can be reliably fixed, thereby facilitating the operation of the power storage device 23.

[0053] In a further preferred embodiment of the present invention, a sponge pad is installed on the limiting plate 27 , and the sponge pad is located on one side of the installation groove, and an L-shaped handle is installed on one side of the connecting plate 21 .

[0054] In this embodiment, after the power storage device 23 is placed in the installation slot, the sponge pads on the two limit plates 27 contact each other, thereby sealing the installation slot. The L-shaped handle design allows the operator to easily grab and move the connection plate 21, making it easier and more efficient to install, remove, or adjust the position of the power storage device 23. The addition of the sponge pad provides an additional protective layer for the power storage device 23, thereby preventing external water vapor and dust from entering the installation slot. The L-shaped handle design allows the operator to easily grab and move the connection plate 21 without using additional tools or applying excessive force. This not only improves the convenience of operation, but also reduces the labor intensity of the operator.

[0055] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0056] In another embodiment of the present invention, U-shaped openings are provided on both sides of the box body 1, and the U-shaped openings are adapted to the power transmission ground wire. A cover plate 31 is hinged on the top of the box body 1, a lock 32 is fixedly installed on one side of the box body 1, and a hook 33 is fixedly installed on one side of the cover plate 31, and the lock 32 is adapted to the hook 33.

[0057] In this embodiment, when the box body 1 needs to be installed on the ground wire, the box body 1 is first placed on the ground wire through the U-shaped opening, and then the cover 31 is closed. The lock buckle 32 is operated to fix the hook 33, and the locking operation of the cover 31 can be completed. Through the cooperation of the hook 33 and the lock buckle 32, the cover 31 can be firmly locked on the box body 1 in the closed state, preventing accidental opening due to vibration or external force, thereby improving the safety during the detection process. The U-shaped opening design allows the power transmission ground wire to easily pass through the box body 1 without complicated connection or adjustment processes, which not only improves work efficiency, but also reduces failures caused by improper connection. Risk, through the coordinated use of the cover 31, the lock 32 and the hook 33, the box 1 can be tightly closed, effectively preventing external dust, moisture or other impurities from entering the box 1, protecting the normal operation of the internal equipment and extending the service life. The closed box 1 design can prevent people from accidentally touching the internal equipment, thereby reducing the risk of safety accidents. At the same time, the firm connection of the lock 32 and the hook 33 also ensures the stability of the box 1 during transportation and use. When it is necessary to open the box 1 for equipment maintenance, replacement or inspection, the operator only needs to simply unlock the lock 32 and the hook 33 to open the cover 31. This design makes the maintenance and operation process simpler and faster.

[0058] In another embodiment of the present invention, a lower clamping block 34 is fixedly installed on one side of the box body 1, and the lower clamping block 34 is located below the U-shaped opening. An electric telescopic rod 35 is fixedly installed on the top of the cover plate 31, and a bracket 36 is fixedly installed on the output rod of the electric telescopic rod 35. The bracket 36 is arranged in a U shape, and an upper clamping block 37 is installed at the bottom of the bracket 36. The upper clamping block 37 is located above the lower clamping block 34 and is in sliding contact with the cover plate 31 and one side of the box body 1. A limit block 38 is fixedly installed on one side of the cover plate 31, and the limit block 38 is slidably connected to the bracket 36.

[0059] In this embodiment, after fixing the cover plate 31, the electric telescopic rod 35 is started, so that the output rod of the electric telescopic rod 35 drives the bracket 36 to slide down, and the bracket 36 drives the upper clamping block 37 to slide down, and at the same time, the bracket 36 slides along the limit block 38 to guide the bracket 36. While the bracket 36 slides down, the upper clamping block 37 slides close to the lower clamping block 34, so that the lower clamping block 34 and the upper clamping block 37 clamp and fix the power transmission ground wire. Through the coordinated use of the upper clamping block 37 and the lower clamping block 34, the ground wire is clamped and fixed, so that the box body 1 is stable. The introduction of the electric telescopic rod 35 makes the sliding process of the upper clamping block 37 more automated and convenient. The operator only needs to control the electric telescopic rod 35 to realize the clamping operation of the clamping block on the ground wire, without manual operation, thereby improving work efficiency. The sliding connection between the limit block 38 and the bracket 36 limits the movement range of the bracket 36, avoiding damage or safety accidents caused by excessive movement of the bracket 36. This design ensures the safety and stability of the box body 1 during the opening and closing process.
