[0033] The embodiment of the application provides a flexible wave receiving device for identifying hidden damage of a power transmission ground wire. Figures 1-10 As shown in the figure, the flexible wave receiving device for identifying hidden damage of the power transmission ground wire comprises a box body 1 and a receiving device 5 arranged in the box body 1 and used for receiving a flexible wave of the power transmission ground wire, the receiving device 5 is composed of a set of hinged arc-shaped components; a bidirectional screw rod 2 rotatably arranged in the box body 1, a set of sliding blocks 3 used for fixing the receiving device 5 on the power transmission ground wire are threadedly sleeved on the bidirectional screw rod 2; connecting rods 4 fixedly arranged on the sliding blocks 3 respectively; a reinforcing cylinder 6 arranged in the box body 1 and used for reinforcing the receiving device 5, the reinforcing cylinder 6 is arranged in an inclined manner; and a driving mechanism arranged in the box body 1 and used for driving the bidirectional screw rod 2 to rotate.

[0034] In the embodiment, when in use, first, the box body 1 is arranged on the power transmission ground wire, then the bidirectional screw rod 2 is rotated to drive the sliding blocks 3 to slide, the sliding blocks 3 drive the connecting rods 4 to slide, so that the connecting rods 4 slide and approach each other, and the connecting rods 4 drive the receiving device 5 to move, so that the arc-shaped components slide and contact the power transmission ground wire, then the reinforcing cylinder 6 reinforces the receiving device 5, so that the receiving device 5 is tightly attached to the power transmission ground wire.

[0035] After the excitation device and the receiving device 5 are installed, the external control device is operated to make the excitation device emit an elastic wave signal of a specific frequency, the elastic wave signal propagates in the ground wire and is reflected or scattered due to defects (such as cracks, corrosion, etc.), the signal emitted by the excitation device propagates axially to both ends of the ground wire, is captured by the receiving device 5 when passing through the receiving device 5 and is converted into analyzable data, and then the receiving device 5 transmits the collected signal to the analysis system to identify hidden damage in the ground wire by analyzing the propagation characteristics (such as wave speed, wave shape change, etc.) of the elastic wave. By using the structure of the bidirectional screw rod 2 and the sliding block 3, the receiving device 5 can be quickly and conveniently fixed on the power transmission ground wire without using bolts or clamps, which greatly improves the installation efficiency. The receiving device 5 is composed of an arc-shaped assembly hinge, which can flexibly adapt to power transmission ground wires of different shapes and sizes, ensuring the comprehensiveness and accuracy of detection. By receiving and analyzing the propagation characteristics of the elastic wave 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 reinforcing cylinder 6 enhances the stability of the receiving device 5, which can maintain stable receiving state even in complex environmental conditions, improving the reliability of the detection results.

[0036] In a further preferred embodiment of the present application, the driving mechanism includes a mounting bracket 7 fixedly installed on the inner wall bottom of the box body 1, the mounting bracket 7 is located above the bidirectional screw rod 2, and a connecting port is formed in the top of the mounting bracket 7; a motor 8 and a mounting plate are fixedly installed on the top of the mounting bracket 7; a set of driving gears 9 are respectively installed on the mounting plate and the bidirectional screw rod 2, the driving gears 9 located on the mounting plate are fixedly connected with the output shaft of the motor 8, a set of the driving gears 9 are engaged, and a set of the driving gears 9 are 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, the output shaft of the motor 8 drives the driving gears 9 to rotate, the driving gears 9 drive another driving gear 9 to rotate, thereby driving the bidirectional screw rod 2 to rotate, the bidirectional screw rod 2 drives the sliding block 3 to slide, thereby realizing the fixation and adjustment of the receiving device 5. By using the driving gear 9 engagement mode to transmit power, the transmission efficiency is high, the transmission ratio is accurate, and the work is stable, which helps to ensure that the bidirectional screw rod 2 can stably and accurately rotate, thereby realizing the accurate fixation and adjustment of the receiving device 5. Since the structure of the driving mechanism is relatively simple and modular, it is more convenient and fast 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, and a threaded rod 12 is rotatably installed on the support plate 11. The threaded rod 12 is threadedly connected to the reinforcing cylinder 6. A buffer pad 13 is installed on the top of the reinforcing cylinder 6. The buffer pad 13 is in sliding contact with the bottom of the receiving device 5. A bevel gear 14 is fixedly sleeved on both the threaded rod 12 and the bidirectional screw 2, and a set of bevel gears 14 mesh with each other.

[0039] In this embodiment, the bidirectional screw 2 rotates simultaneously with the bevel gear 14, which in turn drives the threaded rod 12 to rotate. This rotation of the threaded rod 12 then drives the reinforcing cylinder 6 to slide upwards, bringing it into contact with the housing of the receiving device 5. This ensures the receiving device 5 is tightly fitted against the power transmission ground wire, facilitating the reception of the elastic wave signal emitted by the excitation device. When the reinforcing cylinder 6 approaches the receiving device 5, the buffer pad 13 protects both the reinforcing cylinder 6 and the receiving device 5, preventing the reinforcing cylinder 6 from damaging the receiving device 5. By rotating the bidirectional screw 2 and utilizing the transmission action of the bevel gear 14, the reinforcing cylinder 6 can be easily adjusted. The height is adjustable, thus enabling precise positioning and reinforcement of the receiving device 5. This height-adjustable design allows the receiving device 5 to adapt to different working environments and needs. The buffer pad 13 at the top of the reinforcement cylinder 6 provides effective buffer protection for the receiving device 5, reducing the impact of external impacts and vibrations on the equipment and extending its service life. The fixed installation of the support plate 11 and the threaded connection between the threaded rod 12 and the reinforcement cylinder 6 ensure the stability of the entire adjustment mechanism, allowing the receiving device 5 to remain stable and undisturbed during operation. The lifting and lowering adjustment of the reinforcement cylinder 6 can be achieved by rotating the bidirectional screw 2, which is simple and quick to operate and improves work efficiency.

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

[0041] In this embodiment, the reinforcing cylinder 6 moves along the guide block 16 while sliding, causing the guide block 16 to slide along the guide rod 15. This guides the reinforcing cylinder 6, ensuring its smooth sliding. The cooperation of the guide rod 15 and the guide block 16 provides a stable linear motion track for the reinforcing cylinder 6, helping to maintain its stability and accuracy during the fixing and adjustment of the receiving device 5, preventing 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 reinforcing cylinder 6 are more precise, ensuring that the receiving device 5 can accurately fit onto the power transmission conductor, further improving the reliability and accuracy of the detection.

Through the cooperation 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, and the connection mode can bear greater tension and shear force, so that the receiving device 5 will not be loose or fall off due to external force during detection. The threaded connection mode of the connecting bolt 19 makes the installation and disassembly process simple and fast. When the receiving device 5 needs to be installed, the connecting block 18 is placed on the mounting block 17, and then the connecting bolt 19 is tightened. Similarly, when it needs to be disassembled, the connecting bolt 19 is loosened, and the receiving device 5 can be separated from the connecting rod 4.

[0044] Further preferably, the bottom of the box body 1 is fixedly provided with a counterweight base 20, one side of the counterweight base 20 is provided with a connecting plate 21, one side of the connecting plate 21 is provided with a mounting groove, the mounting groove is provided with a power storage device 23, and the power storage device 23 is electrically connected with the motor 8.

[0045] In the present embodiment, during operation, the storage device 23 converts the stored electrical energy into electrical current through internal chemical reactions and transmits it to the receiving device 5, the motor 8 and the electric telescopic rod 35 on the box 1 through the circuit system. After receiving the electrical energy, these electrical devices start 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 task of detecting the transmission ground wire. Meanwhile, the counterweight base 20 is arranged to make the device more stable when placed or working, reducing the risk of displacement or tipping caused by vibration or external force. Through the arrangement of the counterweight base 20, the overall weight and stability of the receiving device are significantly improved, the shaking and deviation caused by external environmental factors (such as wind, vibration, etc.) are reduced, and the accuracy and reliability of the detection results are improved. The stable device structure reduces the safety hazards caused by shaking or falling, ensuring the safety of the detection personnel and equipment. Although the counterweight base 20 increases the weight of the device, its compact structure and reasonable design make the entire receiving device still maintain high convenience during carrying and installation. The addition of the storage device 23 provides a reliable power supply for the motor 8 and the receiving device 5, enabling the receiving device to operate for a long time without external power supply, prolonging the endurance time and use range of the equipment.

Through the sliding connection design of the trapezoidal slot and the trapezoidal rod 22 and the rotational support of the arc-shaped frame 30 to the trapezoidal rod 22, the connecting plate 21 can be installed on the counterweight base 20 more quickly and conveniently.

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

[0051] In the further preferred embodiment of the application, the limiting plate 27 is threadedly connected with a screw rod 28, one end of the screw rod 28 is provided with a pressing block, and the pressing block is in rotating contact with the blocking piece of the connecting rod 24.

[0052] In the embodiment, when the power storage device 23 needs to be fixed, the operator first opens the slot of the mounting groove by sliding the connecting block 25 and the limiting plate 27, and then places the power storage device 23 in the groove, when the limiting plate 27 slides away from the mounting groove, the screw rod 28 is rotated and moves inward along the thread direction, the pressing block pushes the blocking piece on the connecting rod 24, and the limiting plate 27 is fixed, so that the power storage device 23 is conveniently installed, and the reliable fixation of the connecting block 25 and the limiting plate 27 can be realized through the cooperation of the screw rod 28 and the pressing block, so that the power storage device 23 is conveniently operated.
