The terms "first", "second", etc. in the specification and claims of the present application or the above-mentioned figures are used to distinguish different objects, rather than to describe a specific order; the terms "inside", "outside", "left", and "right" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0034] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] The embodiment of the present invention provides a ground wire flaw detection excitation device and an installation method thereof, such as Figure 1-10 As shown, the ground wire flaw detection excitation device includes: a box body 1 and a support plate 2 installed in the box body 1; an excitation device 3 and a receiving device 4 both arranged on the support plate 2, and the excitation device 3 is used to detect ground wire defects; a connecting plate 5 installed in the box body 1, and a threaded rod 6 is rotatably installed on the connecting plate 5; a threaded barrel 7 threadedly sleeved on the threaded rod 6 for fixing the excitation device 3 and the receiving device 4; and a driving mechanism arranged in the box body 1 for driving the threaded barrel 7 to fix the excitation device 3 and the receiving device 4.

[0036] In this embodiment, when in use, the box body 1 is first fixed on the ground wire, and then the driving mechanism is started, so that the driving mechanism drives the threaded rod 6 to rotate, so that the threaded rod 6 drives the threaded barrel 7 to slide upward. When the threaded barrel 7 slides upward, the top of the threaded barrel 7 slides along the arc parts of the excitation device 3 and the receiving device 4 at the same time. At the same time, multiple arc parts rotate and shrink to form a circle, so that the excitation device 3 and the receiving device 4 are sleeved on the ground wire. After the excitation device 3 and the receiving device 4 are installed, the external control device is operated to make the excitation device 3 send out signals of a specific frequency. These signals propagate in the ground wire and are reflected or scattered due to defects (such as cracks, corrosion, etc.). The signal sent by the excitation device 3 propagates axially to both ends of the ground wire, is captured when passing through the receiving device 4 and converted into analyzable data, which is used to determine whether there are defects in the ground wire and their positions. Then the receiving device 4 transmits the captured signal to the control device, and the ground wire is detected by analyzing the received signal. The excitation device 3 and the receiving device 4 are automatically fixed by motor drive, without manual installation, thereby improving installation efficiency and work efficiency.

[0037] In a further preferred embodiment of the present invention, the driving mechanism includes: a fixed plate 8 fixedly mounted on the bottom of the inner wall of the box body 1; a rotating rod 9 rotatably mounted on the fixed plate 8; a first motor 10 fixedly mounted on the bottom of the inner wall of the box body 1; and a plurality of first bevel gears 11 respectively fixedly mounted on the rotating rod 9, the output shaft of the first motor 10 and the threaded rod 6, and the plurality of first bevel gears 11 are meshed with each other.

[0038] In this embodiment, when installing the excitation device 3 and the receiving device 4, the first motor 10 is first started, so that the output shaft of the first motor 10 drives the first bevel gear 11 to rotate, and the first bevel gear 11 drives the threaded rod 6 to rotate through the synchronous rotation with the rotating rod 9, so that the threaded rod 6 drives the threaded cylinder 7 to slide upward, so that the threaded cylinder 7 installs the excitation device 3 and the receiving device 4. Through the drive of the first motor 10 and the transmission of the first bevel gear 11, the excitation device 3 and the receiving device 4 are fully automatically fixed, which further improves the installation efficiency and convenience.

[0039] In a further preferred embodiment of the present invention, a guide rod 12 is installed on the connecting plate 5, a guide block 13 is slidably installed on the guide rod 12, the guide block 13 is fixedly connected to the threaded barrel 7, the top of the threaded barrel 7 is semicircular, and the threaded barrel 7, the threaded rod 6 and the guide rod 12 are all inclined.

[0040] In this embodiment, driven by the first motor 10, the threaded rod 6 rotates, and the threaded barrel 7 moves along the axial direction of the threaded rod 6 through the cooperation between the thread and the threaded barrel 7. At the same time, since the guide block 13 is fixedly connected to the threaded barrel 7 and slidably installed on the guide rod 12, the movement of the threaded barrel 7 will be constrained by the guide rod 12 to maintain a straight line and stability. This design not only improves the adjustment accuracy, but also ensures the stability of the excitation device 3 and the receiving device 4 during the fixing process. Through the design of the guide rod 12 and the guide block 13, the threaded barrel 7 is effectively prevented from being offset or shaken during the movement, thereby improving the stability of the entire device. At the same time, due to the constraining effect of the guide rod 12, the movement of the threaded barrel 7 is more precise and controllable, thereby improving the adjustment accuracy between the excitation device 3 and the receiving device 4 and the ground wire.

[0041] In a further preferred embodiment of the present invention, the excitation device 3 and the receiving device 4 are both composed of a plurality of arc-shaped parts hinged together, a connecting rod 14 is rotatably installed in the box body 1, a group of connecting ropes 15 are wound around the connecting rod 14, and one end of a group of connecting ropes 15 are respectively connected to the excitation device 3 and the receiving device 4.

[0042] In this embodiment, when the excitation device 3 needs to be removed from the ground wire, the driving mechanism is first started so that the driving mechanism drives the threaded barrel 7 to slide down, thereby causing the threaded barrel 7 to slide down and away from the excitation device 3. While the threaded barrel 7 slides down, the connecting rod 14 rotates, causing the connecting rod 14 to rotate and reel in the connecting rope 15, so that the connecting rope 15 is wrapped around the connecting rod 14. At the same time, one end of the connecting rope 15 drives the arc-shaped parts of the excitation device 3 and the receiving device 4 to move, so that the arc-shaped parts rotate away from the ground wire, thereby facilitating the subsequent disassembly of the box body 1. Through the hinged design of the arc-shaped parts, the excitation device 3 and the receiving device 4 can flexibly adapt to ground wires of different diameters and shapes, thereby improving the versatility and adaptability of the device. Through the coordinated use of the connecting rod 14 and the connecting rope 15, it is convenient to limit the excitation device 3 and the receiving device 4, which is beneficial to subsequent use.

[0043] In a further preferred embodiment of the present invention, a first mounting plate 16 and a second mounting plate 17 are fixedly mounted on the bottom of the inner wall of the box body 1, a first sprocket 18 is provided on the second mounting plate 17 and the connecting rod 14, a first chain 19 is sleeved on a group of the first sprockets 18, the first chain 19 is meshed with a group of the first sprockets 18, the first mounting plate 16 and the output rod of the first sprocket 18 located on the second mounting plate 17 are equipped with a second bevel gear 20, a group of the second bevel gears 20 are meshed, the rotating rod 9 and the output rod of the second bevel gear 20 located on the first mounting plate 16 are fixedly sleeved with a second sprocket 21, a group of the second sprockets 21 are sleeved with a second chain 22, the second chain 22 is meshed with a group of the second sprockets 21.

[0044] In this embodiment, when the driving mechanism is running, the rotating rod 9 drives the second sprocket 21 to rotate synchronously, so that the second sprocket 21 is used in combination with the second chain 22, the second bevel gear 20, the first sprocket 18 and the first chain 19 to realize the synchronous rotation operation of the rotating rod 9 and the connecting rod 14. Then, when the threaded cylinder 7 slides down, the connecting rod 14 reels the connecting rope 15, and when the threaded cylinder 7 slides down, the connecting rod 14 unwinds the connecting rope 15, which is beneficial to the installation operation of the excitation device 3 and the receiving device 4. By introducing the transmission mechanism such as the first chain 19, the second chain 22 and the second bevel gear 20, efficient transmission and conversion of power is realized, and energy loss is reduced. By adjusting the length of the connecting rope 15, the opening angle of the excitation device 3 and the receiving device 4 can be flexibly adjusted.

[0045] In a further preferred embodiment of the present invention, a cover plate 23 is hinged on the top of the box body 1, U-shaped openings are opened on both sides of the box body 1, both U-shaped openings are adapted to the ground wire, and a silicone pad 29 is installed on the top of the threaded tube 7.

[0046] In this embodiment, when the flaw detection excitation device needs to be installed on the ground wire, the box 1 is first placed on the ground wire through the U-shaped opening, and then the driving mechanism is started to move the threaded cylinder 7 along the threaded rod 6 until the silicone pad 29 is in close contact with the excitation device 3 and the receiving device 4. At this time, the excitation device 3 and the receiving device 4 are also in contact with the ground wire through the hinged action of the arc-shaped part of the threaded cylinder 7, and then the detection operation can be carried out. The design of the U-shaped opening and the cover 23 makes the installation and use of the box 1 more convenient, and improves the work efficiency. At the same time, the sealing design of the cover 23 effectively prevents external impurities from entering the interior of the box 1.

[0047] In a further preferred embodiment of the present invention, a card plate 24 is rotatably installed on one side of the box body 1, and the card plate 24 is located on one side of the U-shaped opening. An arc-shaped opening is provided at the bottom of the card plate 24, and the arc-shaped opening is adapted to the ground wire. A positioning groove is provided on one side of the card plate 24, and a positioning block 25 is slidably provided on one side of the box body 1, and the positioning block 25 is in sliding contact with the positioning groove.

[0048] In this embodiment, the device is initially fixed on the ground wire by the cooperation of the U-shaped opening and the box body 1, and then the card plate 24 is rotated so that the arc-shaped opening at the bottom is tightly fitted on the ground wire. Next, the positioning block 25 is slid into the positioning groove on the card plate 24, and the card plate 24 is locked in a fixed position, so that the box body 1 is firmly fixed on the ground wire. After that, the flaw detection work can be started. Through the design of the card plate 24 and the positioning block 25, the fixation of the box body 1 on the ground wire is more firmly and stably, which prevents the risk of sliding or falling off during use. At the same time, the rotation of the card plate 24 and the sliding operation of the positioning block 25 are relatively simple and convenient, which improves the efficiency of installation and disassembly.

[0049] In a further preferred embodiment of the present invention, a connecting block 26 is fixedly installed on one side of the box body 1, and a pull rod 27 is slidably installed on the connecting block 26. One end of the pull rod 27 is fixedly connected to the positioning block 25. A connecting spring 28 is sleeved on the pull rod 27, and both ends of the connecting spring 28 are respectively fixedly connected to the positioning block 25 and the connecting block 26, and the top of the positioning block 25 is arranged in an inclined shape.

[0050] In this embodiment, when the box body 1 needs to be removed, the positioning block 25 is first driven to slide along the connecting block 26 by pulling the pull rod 27 and disengage from the positioning groove on the card plate 24, and then the card plate 24 is rotated to rotate the card plate 24 away from the U-shaped opening, and then the box body 1 can be removed. The design of the pull rod 27 and the connecting spring 28 enables convenient operation of the positioning block 25. The user only needs to simply pull the pull rod 27 to complete the unlocking and locking operations of the positioning block 25. The inclined top design of the positioning block 25 and the reset force of the connecting spring 28 enable the positioning block 25 to be more stably locked in the positioning groove on the card plate 24, preventing loosening or falling off due to vibration or external force during use.

[0051] In a further preferred embodiment of the present invention, a hook 30 is installed on one side of the cover plate 23, a lock 31 is installed on one side of the box body 1, the lock 31 is matched with the hook 30, and a handle is installed on the top of the cover plate 23.

[0052] In this embodiment, when it is necessary to open or close the cover 23 on the box body 1, the locking or releasing operation of the cover 23 can be completed by operating the lock 31 so that the lock 31 fixes or releases the hook 30. Through the cooperation of the hook 30 and the lock 31, the cover 23 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.

[0053] The present invention also provides a method for installing a ground wire flaw detection excitation device, comprising the following steps:

[0054] Step 1: When in use, first open the cover plate 23, slide along the ground wire through the U-shaped opening, so that the ground wire is located in the box body 1, and then rotate the clamping plate 24 to limit the box body 1, so that the box body 1 is fixed on the ground wire, and the box body 1 is quickly installed;

[0055] Step 2: Then start the driving mechanism, so that the output shaft of the first motor 10 drives the first bevel gear 11 to rotate, so that the first bevel gear 11 drives the threaded rod 6 to rotate through the synchronous rotation with the rotating rod 9, so that the threaded rod 6 drives the threaded barrel 7 to slide upward, and the threaded barrel 7 drives the guide block 13 to slide along the guide rod 12 while sliding, so as to ensure the smooth movement of the threaded barrel 7. When the threaded barrel 7 slides upward, the top end of the threaded barrel 7 slides along the arc parts of the excitation device 3 and the receiving device 4 at the same time. At the same time, multiple arc parts shrink to form a circle, so that the excitation device 3 and the receiving device 4 are sleeved on the ground wire, completing the automatic fixing operation of the excitation device 3 and the receiving device 4;

[0056] Step 3: After installing the excitation device 3 and the receiving device 4, operate the external control device to make the excitation device 3 emit a signal. The signal emitted by the excitation device 3 propagates axially toward both ends of the ground wire and is received when passing through the receiving device 4. The receiving device 4 then transmits the captured signal to the control device. By analyzing the received signal, the ground wire is tested.

[0057] Step 4: After the test is completed, slide the threaded tube 7 down away from the excitation device 3 and the receiving device 4, and then remove the box 1 from the ground wire.

[0058] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0059] In another embodiment of the present invention, a group of fixing mechanisms for fixing the box body 1 is provided on one side of the box body 1, and the fixing mechanisms include: a support block 32 fixedly mounted on one side of the box body 1; a bidirectional screw 33 rotatably mounted on the support block 32, and a group of sliders 34 are threadedly sleeved on the bidirectional screw 33; a group of clamping plates 35 respectively fixedly mounted on a group of the sliders 34; a second motor 36 fixedly mounted on one side of the support block 32, and an output shaft of the second motor 36 is fixedly connected to the bidirectional screw 33; a third sprocket 37 fixedly sleeved on the bidirectional screw 33, and a third chain 38 is sleeved on the third sprocket 37, and the third chain 38 is meshed with the third sprocket 37.

[0060] In this embodiment, when it is necessary to fix the box body 1, the second motor 36 is first started to drive the bidirectional screw 33 to rotate. Since a group of sliders 34 are threadedly sleeved on the bidirectional screw 33, as the bidirectional screw 33 rotates, a group of sliders 34 will move in opposite directions. At the same time, a group of sliders 34 slide along the arc plate 39 on the support block 32 and drive the clamping plate 35 close to the ground wire. When the clamping plate 35 is in close contact with the ground wire, continuing to rotate the bidirectional screw 33 will cause the clamping plate 35 to generate sufficient clamping force to firmly clamp the ground wire. In addition, by adjusting the transmission relationship between the third sprocket 37 and the third chain 38, the bidirectional screws 33 on both sides of the box body 1 can be driven, which is convenient for fixing the box body 1. Through the design of the fixing mechanism, the box body 1 can be firmly supported and fixed in different working environments, preventing the occurrence of displacement or tilting due to vibration or external force.

[0061] In another embodiment of the present invention, a counterweight base 40 is installed at the bottom of the box body 1, and a mounting groove 41 is opened on one side of the counterweight base 40. A battery 42 is installed in the mounting groove 41. The battery 42 is used to power the electrical equipment in the box body 1.

[0062] In this embodiment, during the operation of the flaw detection excitation device, the battery 42 converts the stored electrical energy into electric current through an internal chemical reaction, and transmits it to various electrical devices in the box body 1 through the circuit system. After receiving the electric energy, these electrical devices begin to perform their respective functions (such as the rotation of the first motor 10 and the second motor 36 and the detection of the excitation device 3 and the receiving device 4, etc.), thereby completing the flaw detection task. At the same time, the setting of the counterweight base 40 makes the device more stable when placed or working, reducing the risk of displacement or tipping due to vibration or external force.

[0063] In summary, compared with the related art, the present device can perform installation operations on the excitation device 3 and the receiving device 4 more quickly, and the installation efficiency is higher.

[0064] In the several embodiments provided in this application, it should be understood that the disclosed device can be implemented in other ways.

[0065] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the invention.

Based on these embodiments, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
