Description

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a grounding member, which can withstand voltage and mechanical stress, and is widely used in transmission lines, especially in overhead high-voltage transmission lines. Insulators are exposed to the air for a long time and need to be regularly detected to avoid leakage. Currently, when detecting insulators on overhead high-voltage transmission lines, most often workers climb onto the transmission line and then use a handheld detection device to detect the insulators.

[0003] For the existing insulator leakage detection device, reference can be made specifically to the Chinese patent with the publication number CN217901990U, which discloses in detail a high-voltage insulator leakage detection device, including a multimeter body.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment

[0032] Please refer to Figures 1-7As shown in the figure, an insulator leakage detection device includes a device main body 1; a detection end 2 is provided at the bottom end of the device main body 1, and a fixed terminal 3 is fixedly connected to the bottom end of the detection end 2; an adjustment mechanism is provided on the detection end 2 and the fixed terminal 3. The adjustment mechanism includes a probe adjustment component and a length adjustment component. The length adjustment component is arranged between the detection end 2 and the device main body 1, and the probe adjustment component is arranged between the detection end 2 and the fixed terminal 3. The length adjustment component is used to adjust the overall length of the device to facilitate the staff to detect the insulator at high altitude. The probe adjustment component is used to adjust the distance between the fixed terminal 3 and the movable terminal 31 to adapt to different insulators. The probe adjustment component includes a movable terminal 31. The movable terminal 31 is arranged on the right side of the bottom end of the fixed terminal 3. The top end of the movable terminal 31 is fixedly connected with a movable block 32, and the movable terminal 31 is electrically connected to the movable block 32. The movable block 32 is threadedly connected to the outside of a screw rod 33. The screw rod 33 is rotatably connected inside a movable cavity 34. The movable cavity 34 is opened on the fixed terminal 3. The top end of the movable block 32 is in contact with a conductive plate 35, and the movable block 32 is electrically connected to the conductive plate 35. The conductive plate 35 is electrically connected to the detection end 2 through a wire. A transmission component is arranged on the left side of the screw rod 33. The top end of the detection end 2 is fixedly connected with an extension block 61. The extension block 61 is inserted into the inside of the bottom end of the device main body 1. The extension block 61 is electrically connected to the device main body 1 through a wire. The transmission component includes a first pulley 36. The first pulley 36 is fixedly connected to the left side of the screw rod 33, and one end of a transmission belt 37 is sleeved on the outside of the first pulley 36. The other end of the transmission belt 37 is sleeved on the outside of a second pulley 38. The second pulley 38 is fixedly connected to the outside of a transmission shaft 39. The transmission shaft 39 is rotatably connected to the inner wall of a transmission cavity 50. The transmission cavity 50 is opened inside the device main body 1. The transmission belt 37 is in transmission connection with the second pulley 38 and the first pulley 36;

[0033] During operation, when it is necessary to adjust the distance between the fixed terminal 3 and the movable terminal 31, only need to rotate the knob 48 to drive the fixedly connected driving shaft 47 to rotate synchronously, so that the driving shaft 47 drives the connecting shaft 44 to rotate synchronously through the moving block 46 and the moving groove 45. The connecting shaft 44 rotates to drive the fixedly connected socket shaft 40 to rotate synchronously. When the socket shaft 40 rotates, it drives the transmission shaft 39 to rotate synchronously through the cooperation of the first chute 42 and the first spring 43. The transmission shaft 39 rotates to drive the second pulley 38 fixedly connected to its outside to rotate synchronously. The second pulley 38 drives the first pulley 36 to rotate synchronously through the transmission belt 37. The first pulley 36 rotates to drive the screw rod 33 to rotate synchronously, so that the movable block 32 threadedly connected to the screw rod 33 moves inside the movable cavity 34 and drives the fixedly connected movable terminal 31 to move synchronously, achieving the effect of adjusting the distance between the fixed terminal 3 and the movable terminal 31, so as to be able to adapt to different specifications of insulators.

[0034] Further, the length adjustment component includes a socket shaft 40 inserted inside the transmission shaft 39. At both the upper and lower ends of the inner wall of the transmission shaft 39, first sliders 41 are fixedly connected. The first sliders 41 are slidably connected inside first chutes 42, and the first chutes 42 are opened at both the upper and lower ends of the socket shaft 40. A first spring 43 is also arranged inside the transmission shaft 39. The socket shaft 40 is fixedly connected to a connecting shaft 44. A moving groove 45 is opened on the outer side of the connecting shaft 44, and the connecting shaft 44 is inserted inside a driving shaft 47. A moving block 46 is slidably connected inside the moving groove 45, and the moving block 46 is fixedly connected to the inner wall of the driving shaft 47. A first gear 49 is fixedly connected to the outer side of the driving shaft 47. The first gear 49 meshes with a second gear 51. The second gear 51 is rotatably connected to the inner wall of a transmission cavity 50, and a torsion spring 52 is arranged between the second gear 51 and the inner wall of the transmission cavity 50. A rotation limiting component is arranged at the bottom end of the second gear 51. The second gear 51 also meshes with a rack 53. The rack 53 is slidably connected inside the transmission cavity 50, and the top end of the rack 53 is fixedly connected to the bottom end of the device main body 1. One end of the first spring 43 close to the socket shaft 40 is fixedly connected to the socket shaft 40, and the other end of the first spring 43 far from the socket shaft 40 is fixedly connected inside the transmission shaft 39. One side of the torsion spring 52 close to the second gear 51 is fixedly connected to the second gear 51, and the other side of the torsion spring 52 far from the second gear 51 is fixedly connected to the inner wall of the transmission cavity 50. The end of the driving shaft 47 far from the connecting shaft 44 penetrates through the device main body 1 and extends to the outside of the device main body 1, and a knob 48 is fixedly connected to the end of the driving shaft 47 far from the connecting shaft 44. Anti-slip lines are opened on the outer side of the knob 48; when adjusting the length of the whole device, first pull the knob 48 in the direction away from the detection end 2. Under the action of the pulling force, the knob 48 drives the moving block 46 to slide synchronously inside the moving groove 45 through the driving shaft 47, so that the moving groove 45 enters the annular groove on the right side of the moving groove 45. As the driving shaft 47 moves, the first gear 49 fixedly connected to the outer side of the driving shaft 47 also moves synchronously to the position meshing with the second gear 51. At this time, rotate the knob 48 to drive the first gear 49 to rotate through the driving shaft 47. Since the moving block 46 falls into the annular groove inside the moving groove 45, the moving block 46 will not drive the connecting shaft 44 to rotate synchronously when rotating. The rotation of the first gear 49 makes the meshing second gear 51 rotate synchronously. The rotation direction of the second gear 51 is restricted by the rotation limiting component, so that the second gear 51 can only drive the rack 53 to move upward. When the second gear 51 rotates, it drives the meshing rack 53 to move upward to push the device main body 1 to move synchronously, so that the extension block 61 also moves synchronously inside the device main body 1. The extension block 61 is used to maintain the data transmission and circuit connection between the device main body 1 and the detection end 2. When the second gear 51 rotates, it drives the fixedly connected torsion spring 52 to twist synchronously, so that the torsion spring 52 generates elastic deformation.

[0035] Furthermore, the rotation limiting component includes a clamping block 54. A second slider 55 is fixedly connected to the right side of the clamping block 54. The second slider 55 is slidably connected inside a second chute 56. The second chute 56 is formed on the left side of the telescopic block 58. A second spring 57 is also arranged inside the second chute 56. The right side of the second chute 56 is inserted into the inside of a telescopic seat 60. The telescopic seat 60 is fixedly connected to the inner wall of the transmission cavity 50. A third spring 59 is also arranged inside the telescopic seat 60. The top end of the second spring 57 is fixedly connected to the second slider 55, and the bottom end of the second spring 57 is fixedly connected to the inner wall of the second chute 56. One side of the third spring 59 close to the telescopic block 58 is fixedly connected to the telescopic block 58, and the other side of the third spring 59 away from the telescopic block 58 is fixedly connected to the inner wall of the telescopic seat 60;

[0036] During operation, when the second gear 51 rotates forward, the second gear 51 exerts pressure on the arc surface side of the latch 54, causing the latch 54 to move downward under the action of the extrusion force and the arc surface formed thereon. The second slider 55 fixedly connected thereto also slides synchronously inside the second chute 56, and presses the second spring 57, causing the second spring 57 to undergo elastic deformation. After the second gear 51 stops rotating, the extrusion force of the second gear 51 on the latch 54 disappears. At this time, the second slider 55 pushes the latch 54 to return to its original position and engage with the second gear 51 under the action of the restoring force of the second chute 56. When the second gear 51 rotates in the reverse direction, the front side of the latch 54 engages with the second gear 51, preventing the second gear 51 from rotating smoothly, thereby restricting the rotation direction of the second gear 51 and fixing the overall length of the device. When the device needs to be restored to its initial length, only need to continue to pull the knob 48 in the direction away from the detection end 2. At this time, the knob 48 drives the connecting shaft 44 to move synchronously through the driving shaft 47 and the moving block 46. The connecting shaft 44 drives the socket shaft 40 to move synchronously, causing the socket shaft 40 to move and stretch the first spring 43 to produce elastic deformation. During this process, the first gear 49 gradually abuts against the latch 54 as it continuously moves to the right along with the driving shaft 47, and exerts pressure on the latch 54, causing the latch 54 to drive the telescopic block 58 to move into the telescopic seat 60, releasing the restriction on the rotation direction of the second gear 51. At this time, the second gear 51 automatically reverses under the action of the restoring force of the torsion spring 52. The reverse rotation of the second gear 51 drives the first gear 49 to reverse synchronously. The rotation of the first gear 49 drives the driving shaft 47 and the knob 48 to rotate synchronously. By controlling the rotation of the knob 48, the overall shortened length of the device can be controlled. After adjusting to the specified length, release the knob 48. At this time, the socket shaft 40 returns to its original position under the action of the restoring force of the first spring 43 and is inserted back into the transmission shaft 39. Through the connecting shaft 44, the moving groove 45, the moving block 46 and the driving shaft 47, the first gear 49 also moves slightly to the left, releasing the pressure on the latch 54. At this time, the latch 54 and the telescopic block 58 also return to their original positions under the action of the restoring force of the third spring 59, continuing to restrict the rotation direction of the second gear 51.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
