DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-Figure 10 , an intelligent grounding wire device for use in a distribution network, comprising an insulating operating rod 1, a grounding hook 8 and a grounding short-circuit line 7, a pressure sensor 16 is installed on the grounding hook 8, a limiting sleeve 5 is fixedly arranged on the upper end of the insulating operating rod 1, the lower surface of the limiting sleeve 5 is fixedly connected to the upper end of the grounding hook 8, a threaded rod 2 is installed on the inner thread of the insulating operating rod 1, an installation cavity 11 is provided inside the grounding hook 8, a T-shaped plate 19 is slidably installed inside the installation cavity 11, the upper end of the threaded rod 2 is rotatably connected to the T-shaped plate 19, two sliders 12 are slidably installed on the lower inner wall of the installation cavity 11, each slider 12 is provided with a clamping assembly, the clamping assembly comprises a clamping block 9 fixedly installed on the lower surface of the slider 12, the clamping block 9 is set to a hollow structure, one side inner wall of the clamping block 9 is connected to a rotating rod 26 through a first torsion spring 24, and a rotating plate 10 is fixedly connected to the rotating rod 26.

[0020] Two rotating components are provided on the grounding hook 8, each rotating component includes an extrusion plate 6 rotatably installed on the grounding hook 8, and the lower surface of the T-shaped plate 19 is fixedly connected to two moving rods 15 with an L-shaped cross-section, and the surface of each moving rod 15 is in contact with the surface of the corresponding extrusion plate 6. Two ear plates 21 are fixedly connected to the lower inner wall of the installation cavity 11, and one side surface of each ear plate 21 is fixedly connected to a first spring 17, and the first spring 17 is fixedly connected to the corresponding slider 12, and a slide plate 18 is slidably installed on the side of each clamping block 9 away from the pressure sensor 16.

[0021] Two second springs 27 are fixedly connected to the surface of one side of the slide plate 18, and each second spring 27 is fixedly connected to the inner wall of the clamping block 9. When the T-shaped plate 19 moves upward, the two moving rods 15 will be driven to move upward together. When each L-shaped moving rod 15 moves upward, it will push the corresponding extrusion plate 6 to rotate upward. During the upward rotation of each extrusion plate 6, one end of the extrusion plate 6 will move against the surface of the corresponding slide plate 18. Since the elastic force of the second spring 27 is greater than that of the first spring 17, the slide plate 18 and the clamping block 9 will move together first. During the relative sliding of the slider 12 and the grounding hook 8, the first spring 17 is deformed and the distance between the two clamping blocks 9 is reduced.

[0022] A tilted rotating piece 28 is fixedly connected to each rotating rod 26, a cross bar 25 is fixedly connected to one side surface of each slide plate 18, an opening is provided on one side inner wall of the mounting cavity 11, a rotating shaft is rotatably connected to the inside of the opening, a second torsion spring is sleeved on the rotating shaft, one end of the second torsion spring is fixedly connected to the rotating shaft, the other end of the second torsion spring is fixedly connected to the inner wall of the opening, an inclined plate 13 is fixedly connected to the rotating shaft, a telescopic rod 36 is fixedly connected to one side surface of the grounding hook 8, a telescopic end of the telescopic rod 36 is fixedly connected to a mounting plate 38 with a T-shaped cross section, a cleaning sponge 20 is fixedly connected to the lower surface of the mounting plate 38, and the surface of the inclined plate 13 fits with the surface of the mounting plate 38.

[0023] A third spring 37 is fixedly connected to the surface of one side of the mounting plate 38, and the third spring 37 is fixedly connected to the surface of the grounding hook 8. After the surfaces of the two clamping blocks 9 are in close contact with the surface of the wire to be repaired, the T-shaped plate 19 continues to move upward, and the two moving rods 15 continue to drive the two extrusion plates 6 to deflect upward. The extrusion plates 6 will push the slide plate 18 and the clamping block 9 to slide relative to each other, and the second spring 27 will be deformed. During the movement of the cross bar 25 inside the clamping block 9, it will move against the surface of the rotating piece 28, so that the rotating piece 28 rotates, and the rotating rod 26 and the rotating plate 10 rotate at the same time. Since the two rotating plates 10 will change from a parallel setting to an inverted eight-shaped setting, the two extrusion plates 6 will also be in an inverted eight-shaped setting at this time.

[0024] A cavity for the threaded rod 2 to move up and down is provided in the insulating operating rod 1, and a sealing ring 23 is fixedly connected to the upper inner wall of the cavity. An insulating ring 3 is fixedly connected to the outside of the insulating operating rod 1, and an annular elastic waterproof cloth 4 is fixedly connected to the upper surface of the insulating ring 3. A piston (not shown) is clamped on the insulating ring 3. The piston is taken out from the insulating ring 3 to facilitate the drainage of rainwater in the annular elastic waterproof cloth 4. The annular elastic waterproof cloth 4 has good waterproof properties. A cross block 22 is rotatably installed on the threaded rod 2. The cross block 22 and the limiting sleeve 5 are slidably connected. A plurality of sealing cavities 29 arranged in a ring array are provided in the cross block 22, and a sealing plate 35 is slidably installed in each sealing cavity 29. The sealing plate 35 is connected to the inner wall of the sealing cavity 29 through two reset springs 34.

[0025] A rectangular rod 33 is fixedly connected to one side of each sealing plate 35, and multiple rectangular rods 33 are connected by an elastic ring 31. Each rectangular rod 33 is fixedly connected to the elastic ring 31, and the lower surface of the elastic ring 31 is fixedly connected to the upper end of the annular elastic waterproof cloth 4. The upper inner wall of the installation cavity 11 is fixedly connected to the airbag 14. A channel 30 connected to the airbag 14 is opened on the top of the threaded rod 2. A through hole 32 connected to the channel 30 is opened inside each sealing cavity 29. During the process of threaded connection between the threaded rod 2 and the insulating operating rod 1, it will move upward in the cavity, and the cross block 22 and the T-shaped plate 19 will move up at the same time. In the initial state, the annular elastic waterproof cloth 4 is in a folded state. During the upward movement of the cross block 22, the elastic ring 31 will be driven to move up together, thereby causing the annular elastic waterproof cloth 4 to change from a folded state to an unfolded state.

[0026] After the airbag 14 is squeezed by the T-shaped plate 19, the gas inside it will be evenly transported to the inside of each sealing cavity 29. After the gas enters the inside of the sealing cavity 29, it will push the sealing plate 35 to slide inside the sealing cavity 29, and the reset spring 34 will be deformed. In the process of multiple rectangular rods 33 extending to the outside of the cross block 22 at the same time, the elastic ring 31 will be stretched and deformed at the same time, and drive the annular elastic waterproof cloth 4 to expand outward, and the annular elastic waterproof cloth 4 will change from a cylindrical shape to a truncated cone with a larger upper bottom diameter.

[0027] In the present invention, when in use, the ground nail (not shown) at one end of the ground short-circuit line 7 is inserted into the ground, and then the insulating operating rod 1 is held by hand to hang the ground hook 8 on the outside of the wire to be repaired, that is, the wire to be repaired is in the space surrounded by the concave ground hook 8, and the two clamping blocks 9 are located on both sides of the wire to be repaired, and then the threaded rod 2 is rotated. During the process of the threaded connection between the threaded rod 2 and the insulating operating rod 1, it will move up in the cavity. Since the T-shaped plate 19 and the cross block 22 are both rotatably connected to the threaded rod 2 and cannot be The cross block 22 and the T-shaped plate 19 will slide relative to the threaded rod 2 along the axial direction of the threaded rod 2, and the airbag 14 will be squeezed during the upward movement of the T-shaped plate 19. Only the upper surface of the airbag 14 is fixedly connected to the upper inner wall of the installation cavity 11, and the other surfaces of the airbag 14 are only in contact with the inner wall of the installation cavity 11. The lower surface of the airbag 14 is always in contact with the upper surface of the T-shaped plate 19, and the sealing performance is good during the contact. During the upward movement of the T-shaped plate 19, the airbag 14 will be squeezed.

[0028] In the initial state, the annular elastic waterproof cloth 4 is in a folded state. When the cross block 22 moves upward, the elastic ring 31 is moved upward together, so that the annular elastic waterproof cloth 4 changes from the folded state to the unfolded state. Since the airbag 14 has only one air hole, and the air hole is connected to the channel 30, and a sealing hole connected to the air hole is opened on the T-shaped plate 19, after the airbag 14 is squeezed, the gas inside it will be uniformly transported to the inside of each sealed cavity 29 through the air hole, the sealing hole, the channel 30 and the plurality of through holes 32 in sequence. Since each sealing plate 35 is connected to the corresponding The sealing performance of the inner wall of the sealing chamber 29 is good when it is connected. After the gas enters the interior of the sealing chamber 29, it will push the sealing plate 35 to slide inside the sealing chamber 29. Since the two ends of each reset spring 34 are respectively fixedly connected to the sealing plate 35 and the inner wall of the sealing chamber 29, the reset spring 34 is deformed. In the process of multiple rectangular rods 33 extending to the outside of the cross block 22 at the same time, the elastic ring 31 is stretched and deformed at the same time, and drives the annular elastic waterproof cloth 4 to expand outward. The annular elastic waterproof cloth 4 will change from a cylindrical shape to a truncated cone with a larger upper bottom diameter.

[0029] When there is residual rainwater around the wire to be tested, the annular elastic waterproof cloth 4 with an isosceles trapezoidal cross-section can store and block rainwater sliding down the insulating operating rod 1, so as to prevent rainwater from directly contacting the hands during the process of sliding down the insulating operating rod 1, thereby reducing the risk of electric shock and being beneficial to improving the personal safety of the operator. The grounding wire device has high safety when in use. During the upward movement of the T-shaped plate 19, the two moving rods 15 will be driven to move up together. When each L-shaped moving rod 15 moves up, it will push the corresponding extrusion plate 6 to rotate upward. During the upward rotation of each extrusion plate 6, one end of the extrusion plate 6 will move against the surface of the corresponding slide plate 18. Since the elastic force of the second spring 27 is greater than that of the first spring 17, the slide plate 18 and the clamping block 9 will move together first. During the relative sliding of the slider 12 and the grounding hook 8, the first spring 17 is deformed and the distance between the two clamping blocks 9 is reduced.

[0030] During the upward movement of the T-shaped plate 19, it moves upward against the lower surface of the inclined plate 13 (as shown in the attached Figure 5 As shown), the inclined plate 13 and the grounding hook 8 are relatively rotated, the second torsion spring is deformed, and during the downward rotation of one end of the inclined plate 13, under the elastic force of the third spring 37, the mounting plate 38 moves toward the direction close to the grounding hook 8, and the telescopic rod 36 is deformed. In the initial state, the cleaning sponge 20 is located outside the two clamping blocks 9. During the movement of the cleaning sponge 20 with the mounting plate 38, it passes between the two clamping blocks 9, and the cleaning sponge 20 passes between the pressure sensor 16 and the wire to be repaired. During this process, the surfaces of the two clamping blocks 9 are respectively in contact with the surfaces on both sides of the wire to be repaired. During the movement of the cleaning sponge 20, it moves along the surface of the wire to be repaired, thereby scraping off rainwater or impurities attached to the surface of the wire to be tested, so as to avoid rainwater or impurities adhering to the pressure sensor 16 when the wire to be tested subsequently contacts the surface of the pressure sensor 16, thereby damaging the pressure sensor 16. This is beneficial to the protection of the pressure sensor 16 and to extending the service life of the grounding wire device.

[0031] As the T-shaped plate 19 moves upward, it will gradually stagger with the inclined plate 13. Then, under the elastic force of the second torsion spring and the third spring 37, the inclined plate 13 and the mounting plate 38 move to the initial position, that is, the cleaning sponge 20 is located outside the two clamping blocks 9. Then, as the T-shaped plate 19 continues to move upward, the surfaces of the two clamping blocks 9 will be in close contact with the surfaces of the wires to be repaired. In the subsequent process of the T-shaped plate 19 continuing to move upward, the two moving rods 15 continue to drive the two extrusion plates 6 to deflect upward, and the extrusion plates 6 will push the slide plate 18 The second spring 27 slides relative to the clamping block 9, and the cross bar 25 moves against the surface of the rotating piece 28 during the movement inside the clamping block 9, so that the rotating piece 28 rotates, and the rotating rod 26 and the rotating plate 10 rotate at the same time. Since one end of each first torsion spring 24 is fixedly connected to the corresponding rotating rod 26, and the other end is fixedly connected to the corresponding clamping block 9, the first torsion spring 24 is deformed, and the two rotating plates 10 are changed from a parallel setting to an inverted eight-shaped setting. At this time, the two extrusion plates 6 are in an inverted eight-shaped setting.

[0032] During the rotation of the two rotating plates 10, the wire to be inspected will be pushed upward at the same time, and the wire to be inspected will slide relative to the relatively smooth surfaces of the two clamping blocks 9 at the same time, until the surface of the wire to be inspected is in close contact with the pressure sensor 16, and the external single-chip microcomputer (not shown) can read the value of the pressure sensor 16 (the single-chip microcomputer and the pressure sensor 16 have been disclosed in the patent document with publication number CN104716522A, and its working principle is not described in detail), so as to know the stress condition of the pressure sensor 16, and then judge whether the wire to be inspected is clamped, and quickly judge whether the grounding hook 8 has been fully hooked on the wire to be inspected, which is beneficial to improve the personal safety of the personnel working on the phenomenon, and personal safety can be effectively guaranteed, which is beneficial to the use of the grounding wire device.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
