Description

Technical Field

[0001] This invention relates to the technical field of eliminating overheating in drain outlets, specifically to a device for eliminating overheating defects in drain outlets by applying an electric current. Background Technology

[0002] In substations or distribution networks, current busbars, as key connecting components for current transmission, are constantly in operation. Affected by factors such as vibration from the main equipment, wind loads, thermal expansion and contraction, and environmental corrosion, the connecting bolts of the current busbars are prone to loosening, corrosion, and inadequate tightening, leading to abnormally increased contact resistance and subsequent overheating defects. If these overheating defects are not addressed promptly, they can cause minor issues like energy loss and equipment performance degradation, or more serious problems such as burning, wire breakage, or even power outages, severely threatening the safe and stable operation of the power grid.

[0003] For example, Chinese Patent Publication No. CN114473469A discloses a bolt fastening device, robot, and method for overhead transmission line diverter plates. The device includes a feeding section, a flexible sleeve section, and a nut fastening section. The flexible sleeve section is located on the bolt side of the diverter plate, and the nut fastening section is located on the nut side of the diverter plate. The flexible sleeve section and the nut fastening section are mounted opposite each other on both sides of the feeding section. The feeding section drives the flexible sleeve section and the nut fastening section to move simultaneously towards the center, respectively approaching the head of the diverter plate bolt and the nut to be fastened, thereby achieving the purpose of fastening the diverter plate bolt.

[0004] For example, Chinese Patent Publication No. CN119610010A discloses a live bolt fastening device for a substation, including an insulating sleeve, a fastening rod rotatably disposed inside the insulating sleeve, a fastening sleeve disposed at the top of the fastening rod, and an adjusting rod connected to the bottom end of the fastening rod extending from the bottom of the insulating sleeve. The adjusting rod is arranged perpendicularly to the fastening rod. Both the fastening rod and the adjusting rod are made of insulating material. During operation, rotating the adjusting rod drives the fastening rod to rotate, and the fastening sleeve rotates synchronously to complete the fastening of the bolt.

[0005] For example, Chinese Patent CN220679954U discloses a tool for disassembling and assembling a diversion plate for a high-voltage live-line working robot, including a bolt fixing assembly, an electric wrench assembly, and an industrial camera; the bolt fixing assembly is detachably mounted on the electric wrench assembly, and the electric wrench assembly is equipped with an industrial camera; the bolt fixing assembly is used to fix the bolts in the diversion plate bolt and nut assembly disassembled by the electric wrench assembly, so as to realize the single-handed disassembly of the diversion plate bolt and nut assembly by the electric wrench assembly; the industrial camera is used to collect image information of the diversion plate bolt and nut.

[0006] In summary, existing technologies for eliminating heat generation during drainage have many drawbacks, which are summarized below: ① The treatment of overheating defects in drain pipes often involves power outage maintenance, which requires interrupting the power supply, but existing live-line working tools have many shortcomings; ② Poor compatibility; it can only match a single specification or type of bolt and cannot be compatible with multiple types of bolts such as external hexagon, internal hexagon, and Phillips head. ③ Rusty bolts are difficult to remove or tighten easily; ④ Without remote viewing capability, it is impossible to accurately align bolts in high-altitude or confined spaces, resulting in high operational difficulty and low efficiency; ⑤ During tightening, the bolt and nut may rotate synchronously, making it impossible to lock effectively; ⑥ The existing fastening devices using motor screws or robotic arms are not entirely suitable for the complex environment of substations or distribution networks. They have insufficient insulation protection, making it difficult to meet the safety requirements for live-line work. They also require regular maintenance. In addition, the manual fastening or disassembly structures do not have any force-enhancing measures, which makes it impossible to turn when encountering rusted bolts. Summary of the Invention

The connector 1 is connected to the input shaft of the harmonic reducer 3, and the reducer mounting base 2 is fixed to the harmonic reducer 3. A rotary flange 4 is connected to the output end of the harmonic reducer 3. The quick-connect female part 5 is connected to the rotary flange 4. The monitor mounting bracket 6 is connected to the column 17. The wireless monitor 7 is connected to the monitor mounting bracket 6. The first quick-change hexagonal sleeve 8 is connected to the quick-connect female part 5. The second quick-change hexagonal sleeve 9 is connected to the quick-connect fixing female part 10. The quick-connect fixing female part 10 is connected to the connecting seat 13, and a flat key 11 is engaged between the connecting seat 13 and the quick-connect fixing female part 10. The connecting seat 13 is slidably mounted on the column 17 and is limited by a ratchet pawl 15. One end of the spring 12 is connected to the upper pin 18, and the other end is connected to the lower pin 20. The round nut 14 is locked to the quick-connect fixing part 10. The pawl 15 is connected to the cylindrical pin 16, which is connected to the column 17. The upper pin 18 is connected to both sides of the connecting seat 13, and the lower pin 20 is connected to both sides of the reducer mounting base plate 2. The pull ring 19 is provided with a trigger wire, which passes through the column 17 and the connecting seat 13 and is connected to the pawl 15. The first quick-change hexagonal sleeve 8 and the second quick-change hexagonal sleeve 9 are both replaceable structures to adapt to different bolts. The first quick-change hexagonal sleeve 8 is detachably connected to the quick-connect female component 5, and the second quick-change hexagonal sleeve 9 is detachably connected to the quick-connect fixing female component 10. The monitor mounting bracket 6 is movably positioned connected to the column 17. The connector 1 has a slot at its end, and the column 17 has a slot to limit the displacement of the connector seat 13. The column 17 has a through slot in the middle for threading a trigger wire. The flat key 11 is used to fix the quick-connect fixing female component 10 and limit the rotation of the quick-connect fixing female component 10 relative to the connector seat 13. The connector seat 13 has a through hole for threading the trigger wire. The trigger wire is made of insulating material.

[0021] First step of preparation: According to the type of bolts of the substation drain, there are usually external hexagonal, internal hexagonal, cross bolts, etc. Select the corresponding first quick-change hexagonal socket 8 and second quick-change hexagonal socket 9, and install them on the quick-connect female part 5 and quick-connect fixed female part 10 respectively by quick-connect method. Fix the insulating operating rod to the slot of the connector 1, and check whether the signal transmission of the wireless monitor 7 is normal to ensure that the bolt position image can be clearly captured. The second step is positioning: The operator holds the insulated operating rod and moves the device to the bolt position corresponding to the overheating defect of the drain. Through the real-time image transmitted by the wireless monitor 7, the operator adjusts the angle and height of the device so that the first quick-change hexagonal sleeve 8 is aligned with the bolt head on the upper side of the drain and the bolt is tightened. Then, the pull ring 19 is pulled. The pull ring 19 drives the trigger line to release the pawl 15 from the limit of the connecting seat 13. Under the elastic tension of the tension springs 12 on both sides, the connecting seat 13 slides down along the slot of the column 17, driving the second quick-change hexagonal sleeve 9 to move down until the second quick-change hexagonal sleeve 9 is aligned with and tightens the nut on the lower side of the drain. The third step is bolt tightening: The operator rotates connector 1 clockwise using the insulated operating rod. Connector 1 drives the input shaft of harmonic reducer 3 to rotate. Through the multiplier effect of the harmonic reducer 3, its output end drives the rotating flange 4, quick-connect female part 5, and the first quick-change hexagonal sleeve 8 to rotate synchronously, locking the nut on the lower side of the drain. During this process, the second quick-change hexagonal sleeve 9 is fixed with the connecting seat 13 under the action of the flat key 11, clamping the upper bolt to prevent the upper bolt from rotating synchronously with the lower nut, avoiding simultaneous rotation, ensuring that the nut is locked in place, effectively reducing contact resistance and eliminating overheating defects. Step 4: After tightening the nut, stop rotating the insulating operating rod and pull it backward. Simultaneously pull the pull ring 19 to lift the pawl 15, causing the connecting seat 13 to move upward as a whole. Then release the pull ring 19 and lower the pawl 15, allowing the connecting seat 13 to re-engage and be limited on the pawl 15. The first quick-change hexagonal sleeve 8 and the second quick-change hexagonal sleeve 9 will separate from the nut and bolt respectively, completing the operation of eliminating overheating defects while energized. If other bolts need to be tightened or loosened, repeat the above steps.
