Description

Technical Field

[0001] This invention relates to the field of power detection technology, specifically to a method for detecting power faults. Background Technology

[0002] Leakage current detectors can detect the operating current of current-type electric shock protectors and unbalanced leakage currents that are less than the operating current of current-type electric shock protectors. They can also distinguish between leakage voltages that are harmful to the human body and induced voltages that are harmless to the human body. They can effectively detect leakage phenomena in electrical appliances. When a leakage fault occurs, the usual method is to tie the leakage current detector to a long pole, then hold the long pole to bring the leakage current detector close to the cable, and then move and shake the leakage current detector to test the cable. This detection method is time-consuming, labor-intensive, and inefficient.

[0003] As described in application number 202210679057.3, a power fault detection device is installed on the detection line, with the wire positioned in a horizontal channel. A control component rotates a cover plate, causing a sliding component on the cover plate to contact the wire, allowing the device to slide on the detection line. During this sliding process, a leakage current detector detects the leakage point in the line, thus determining the leakage location. Once the leakage location is found, the sliding component stops, and a positioning component fixes the device at the leakage location, facilitating subsequent maintenance by repair personnel.

[0004] Based on the above information, it can be seen that using a single pulley to contact the cable and moving the device by rotating the pulley cannot guarantee effective movement. In everyday life, cables are not horizontal but have a certain degree of sag. When using a single pulley, it is impossible to guarantee sufficient friction between the pulley and the cable, affecting movement. Furthermore, when cables are exposed to the external environment for a long time, bird droppings and other impurities easily adhere to their surface, increasing the weight of the cable and hindering the movement of the pulley on the cable, thus affecting the leakage current detector's ability to detect cable leakage. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a power fault detection method that solves the problem that when performing leakage current detection, the conventional single pulley drive method cannot ensure that the pulley moves effectively along the cable, thus affecting the leakage current detector's ability to detect cable leakage.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a power fault detection method, specifically comprising the following steps:

[0009] Step 1, Mounting: Place the leakage current detector in the suspension assembly, put the guide component in the suspension assembly onto the cable to be tested, and then pull the guide component upward to make the test cable lock in the suspension assembly;

[0010] Step 2, Locking: During the upward pulling of the guide component in Step 1, the guide component drives the power frame to slide down through the steering component. During this process, the detachable snap-fit ​​component limits the upward movement of the power frame, thus locking the position of the guide component.

[0011] Step 3, Positioning: During the downward movement of the power carrier in Step 2, the drive component approaches the cable to be tested and adheres to the upper surface of the cable. As the drive component continues to move, the lifting component approaches the cable to be tested and adheres to the lower surface of the cable, thus completing the lifting of the cable to be tested.

[0012] Step 4, Cleaning and Adhesion: During the upward movement of the guide component in Step 1, the upper cleaning component adheres to the upper surface of the cable to be tested and squeezes the upper surface of the cable. When the guide component is placed on the cable to be tested in Step 1, the lower cleaning component adheres to the lower surface of the cable to be tested and squeezes the lower surface of the cable.

[0013] Step 5, Moving Detection: Activate the drive component to move the leakage current detector along the cable to be tested. When a leakage current is detected, the leakage current detector will sound an alarm and shut down the drive component.

[0014] Step Six, Moving Cleaning: During the startup of the drive component in Step Five, the upper cleaning component and the lower cleaning component move along the cable to be tested and wipe and clean the surface of the cable to be tested.

[0034] This invention provides a method for detecting power faults. It has the following beneficial effects:

[0035] (1) By placing the leakage current detector in the suspension assembly, and with the setting of the guide assembly, steering assembly, power frame, lifting assembly and upper cleaning assembly, after the cable is placed in the guide assembly, the guide assembly can be moved to ensure that the leakage current detector can effectively move along the cable during the operation of the drive assembly. With the setting of the detachable snap-fit ​​assembly, the stability of the connection between the device and the cable is ensured, and the safety during use is guaranteed. With the setting of the upper cleaning assembly and the lower cleaning assembly, the surface of the cable is cleaned during the movement of the device, ensuring the stable movement of the device.

[0036] (2) The present invention limits the position of the cable by setting up the concave block, sleeve, push rod and first spring, so that the cable can be placed between the rubber wheel and the lifting wheel, so that the device has a precise positioning and assembly effect.

[0037] (3) By utilizing the first I-shaped block, the first toothed plate, the gear, the second toothed plate and the second I-shaped block, when the L-shaped frame rises, the second I-shaped block drives the first rotating shaft to fall, so that the rubber wheel can stably adhere to the upper surface of the cable. As the L-shaped frame continues to rise, the rubber wheel can stably squeeze the cable, thereby ensuring the contact and adhesion between the lifting wheel and the lower surface of the cable, thus realizing the position limitation of the cable.

[0038] (4) The present invention uses the combination of top rod, swing plate, drive slide plate and stepped groove to realize the movement of L-shaped frame by rotating swing plate. This makes it convenient to limit the position of cable. With the setting of eccentric plate, first extrusion rod, first limit plate, third spring, first elastic net and first elastic wiping plate, when swing plate rotates, it ensures stable contact between the first elastic wiping plate and the upper surface of cable and applies extrusion force to cable, thereby ensuring the friction between rubber wheel and cable. With the setting of drive motor and first rotating shaft, it ensures that the device can move effectively along cable, clean the upper surface of cable and ensure that leakage current detector can move effectively along cable for leakage current detection. With the setting of fourth spring, it provides convenient conditions for the reset of L-shaped frame.

[0039] (5) The present invention uses the cooperation of several right-angled triangular prisms, square prisms, second springs and fixed cylinders. When the second I-shaped block drives the first rotating shaft to lower the rubber wheel, the right-angled triangular prisms squeeze the square prisms, which in turn squeeze the second spring. When the right-angled triangular prisms are not in contact with the square prisms, the second spring pushes the square prisms to reset, thereby limiting the rise of the second I-shaped block and ensuring the stability of the contact between the rubber wheel and the cable. With the rope removal mechanism, pulling the rope can make the square prisms detach from the right-angled triangular prisms, providing convenient conditions for the separation of the device from the cable.

[0040] (6) In this invention, the upper baffle and the lower baffle work together. During the process of the first rotating shaft driving the rubber wheel to descend, the first rotating shaft drives the upper baffle to descend. During the process of the second rotating shaft driving the lifting wheel to rise, the second rotating shaft drives the lower baffle to rise. This achieves the sealing of the assembly port, ensuring that the device can be stably fitted around the cable and achieve the effect of preventing fall.

[0041] (7) The present invention uses the positioning cylinder, the sixth spring, the positioning rod and the grooved inclined plate to squeeze the grooved inclined surface when the cable enters the L-shaped frame from the assembly port, so that the grooved inclined plate moves downward. With the setting of the slot, the second limiting plate, the second squeezing rod, the fifth spring, the second elastic net and the second elastic wiping plate, the second elastic wiping plate is effectively attached to the lower surface of the cable, so that the device can clean the lower surface of the cable during the movement, ensuring the thoroughness of the cleaning.

Detailed Implementation

[0056] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0057] Please see Figures 1-13 The present invention provides the following two technical solutions:

[0058] Example 1: A power fault detection method, specifically including the following steps:

[0059] Step 1, Installation: Open the inspection door 67, place the battery 68 and leakage current detector 1 in the work cover 66. The battery 68 is a rechargeable lithium battery used to power the leakage current detector 1 and the drive motor 70. Close the inspection door 67, and place the device along the assembly port 16 onto the cable to be tested. The cable to be tested moves into the L-shaped frame 17, and the cable to be tested presses against the concave block 23. The concave block 23 pushes the push rod 21 to compress the first spring 22. When the cable to be tested moves into the rubber... After the wheel 34 and the two lifting wheels 43 are in place, the swing plate 44 is rotated. The swing plate 44 drives the drive slide plate 52 to move. The drive slide plate 52 drives the top rod 45 to rise. The top rod 45 drives the L-shaped frame 17 to rise. During the rise of the L-shaped frame 17, the first toothed plate 27 is driven to rise. The first toothed plate 27 drives the first I-shaped block 18 to rise along the first slide groove 19. The first I-shaped block 18 drives the second rotating shaft 40 to make the lower baffle 42 rise along the second moving groove 41 to seal the assembly port 16.

[0060] Step 2, Locking: During the upward movement of the first toothed plate 27 in Step 1, it drives the gear 26 to rotate. The gear 26 drives the second toothed plate 28 to move downward. During the downward movement of the second toothed plate 28, the second toothed plate 28 drives the second I-shaped block 24 to move downward along the second slide groove 25. During this process, the second I-shaped block 24 drives several right-angled triangular prisms 30 to descend. The right-angled triangular prisms 30 continuously contact and squeeze the square prism 31 and then disengage from the squeezing square prism 31. When the square prism 31 is squeezed, it squeezes the second spring 32. When the right-angled triangular prism 30 disengages from the square prism 31, the second spring 32 pushes the square prism 31 to reset, preventing the right-angled triangular prism 30 that has squeezed the square prism 31 from rising.

[0061] Step 3, Positioning: During the downward movement of the second I-shaped block 24 in Step 2, it drives the first rotating shaft 33 to move the rubber wheel 34 downward, close to the cable to be tested, and then close to the upper surface of the cable to be tested. As the second I-shaped block 24 continues to move, the first I-shaped block 18 in Step 1 continues to rise along the first slide groove 19. During this process, the first I-shaped block 18 drives the second rotating shaft 40 to move the lifting wheel 43 close to the cable to be tested and close to the lower surface of the cable to be tested, thus completing the lifting of the cable to be tested.

[0062] Step 4, Cleaning and Adhesion: During the rotation of the swing plate 44 in Step 1, the eccentric plate 46 moves towards the cable to be tested. After the first elastic wiping plate 51 contacts the upper surface of the cable to be tested, it squeezes the upper surface of the cable. The first elastic wiping plate 51 is made of elastic sponge. During the process, the first elastic wiping plate 51 squeezes the first squeezing rod 47. The first squeezing rod 47 drives the first limiting plate 48 to move upward. The first limiting plate 48 stretches the third spring 49, so that the first elastic wiping plate 51 adheres to the upper surface of the cable to be tested.

[0063] Step 5, Movement Detection: Start the drive motor 70, which is a servo motor electrically connected to the battery 68 and controlled by a control switch. The drive motor 70 drives the first rotating shaft 33 to rotate the rubber wheel 34. The rubber wheel 34 moves along the cable to be tested, so that the entire device moves along the cable to be tested. During the process, the leakage current detector 1 performs leakage current detection on the cable to be tested. When a leakage current is detected, the leakage current detector 1 issues an alarm, shuts off the drive motor 70, and marks the location where the alarm was issued as the leakage point.

[0064] Step Six, Moving and Cleaning: During the movement of the entire device in Step Five, the first elastic wiping plate 51 moves along the cable to be tested and wipes and cleans the upper surface of the cable to be tested.

[0065] In this embodiment, with the cooperation of the rubber wheel 34, the lifting wheel 43 and the first elastic wiping plate 51, the rubber wheel 34 is in close contact with the cable to be tested. When the rubber wheel 34 rotates, it can effectively drive the device to move along the cable to be tested. The first elastic wiping plate 51 removes impurities from the upper surface of the cable to be tested, further ensuring the effective movement of the device. In addition, the cooperation of the fixed cylinder 29, several right-angled triangular prisms 30, square prisms 31 and the second spring 32 realizes the convenient, safe and stable assembly between the cable to be tested and the device.

[0066] Example 2, as an improvement on the previous example, the power fault detection method further includes the following steps:

[0067] Step 7: Limiting: In Step 1, the device is placed on the cable to be tested along the assembly port 16. During the process of moving the cable to be tested to the L-shaped frame 17, the cable to be tested is squeezed along the inclined slope surface of the grooved plate 56. The grooved plate 56 squeezes the sixth spring 65 through the positioning rod 64. When the cable to be tested moves between the rubber wheel 34 and the two lifting wheels 43 in Step 1, the cable to be tested falls into the slot 57 and squeezes the second elastic wiping plate 62. The second elastic wiping plate 62 pushes the second extrusion rod 58 downward through the second elastic net 61. The second extrusion rod 58 drives the second limiting plate 59 downward. The second limiting plate 59 stretches the fifth spring 60. At this time, the second elastic wiping plate 62 is in contact with the lower surface of the cable. The second elastic wiping plate 62 is made of elastic sponge.

[0068] In step three, when the lifting wheel 43 lifts the cable to be tested, the sixth spring 65 pushes the positioning rod 64 to raise the grooved inclined plate 56, ensuring effective contact between the second elastic wiping plate 62 and the cable to be tested.

[0069] During the downward movement of the rubber wheel 34 in step three, the first rotating shaft 33 drives the upper baffle 38 to descend along the first moving groove 35 to seal the assembly port 16.

[0070] Step 7: Cleaning: During the movement of the entire device in Step 5, the second elastic wiping plate 62 moves along the cable to be tested and wipes and cleans the lower surface of the cable to be tested;

[0071] Step 8: Separation: After completing the leakage detection, pull the disassembly rope 69 to disengage the square column 31 from the limit of the right-angled triangular column 30. The fourth spring 54 extends, causing the L-shaped frame 17 to move downward. During this process, the rubber wheel 34, the lifting wheel 43, and the first elastic wiping plate 51 all move away from the cable to be tested. Remove the cable to be tested from the assembly port 16 to complete the separation of the device from the cable to be tested.

[0072] The advantages of Embodiment 2 compared to Embodiment 1 are: it can also clean the lower surface of the cable to be tested, ensuring thorough cleaning; and with the setting of the baffle 38, the assembly port 16 is sealed, further ensuring the safety and stability of the device on the cable to be tested; and with the setting of the rope removal 69, the device and the cable to be tested can be easily separated, making it more convenient to use.
