[0030] according to Figure 6-Figure 8 As shown, the inner walls of the two sponge sleeves 403 are respectively in contact with the outer surfaces of the two terminal bodies 401 near the bottom, and a plurality of liquid flow tubes 411 are evenly divided into two groups, one end of the two groups of liquid flow tubes 411 are respectively fixed and penetrate into the interior of the two annular sleeves 402, and one end of the two groups of liquid flow tubes 411 are respectively extended to the interior of the two sponge sleeves 403, and a plurality of springs 413 are evenly divided into four groups, and the acetic acid solution can be transported to the sponge sleeves 403 through the liquid flow tubes 411, and then the acetic acid solution is coated on the outer surface of the terminal body 401 to dissolve the rust stains.
[0031] according to Figure 7-Figure 8As shown, one end of four groups of springs 413 are respectively fixedly connected to the inner walls of four pressing plates 406, wherein the other ends of two groups of springs 413 are fixedly connected to the outer surface of one of the annular plates 404, and the other ends of the other two groups of springs 413 are fixedly connected to the outer surface of another annular plate 404, the outer surfaces of the two annular plates 404 are provided with a plurality of sealing holes 418, the inner walls of the plurality of sealing holes 418 are fixedly connected with sealing rings 414, the outer surfaces of the plurality of ejector pins 412 are respectively fitted with the inner walls of the plurality of sealing rings 414, the springs 413 facilitate elastic support of the pressing plate 406, and under the sealing action of the sealing ring 414, the solution inside the annular solution capsule 405 can be prevented from leaking out.
[0032] according to Figure 1 , Figure 4 , Figure 6 and Figure 8-Figure 9 As shown, the inner walls of the two arc-shaped solution covers 415 are fixedly mounted with a plurality of support blocks 416, and the plurality of support blocks 416 are evenly divided into two groups, and the tops of the two groups of support blocks 416 are respectively in contact with the bottoms of the two annular solution capsules 405, and the conductive block 305 is provided with a mounting groove 307 at the top near the rear surface, and the bottom ends of the two terminal bodies 401 are fixedly mounted on the bottom surface inside the mounting groove 307, and the outer surfaces of the two terminal bodies 401 near the bottom ends are provided with gaskets 9, and the bottoms of the two gaskets 9 are in contact with the bottom surface inside the mounting groove 307, and the annular solution capsules 405 are supported by the support blocks 416 to prevent them from falling into the arc-shaped solution cover 415, causing the flow holes on the inner bottom surface thereof to be blocked.
[0033] The effect achieved by the entire mechanism is as follows: when in use, the control switch 203, the first prompt light 204, the second prompt light 205, the battery 206, the first electric push rod 302, the second electric push rod 501, the current sensor 504 and the PLC controller 207 are electrically connected, and the battery 206 is used to power other devices, and the corresponding operation instructions are sent to the PLC controller 207 through the control switch 203, and then the corresponding device is controlled to start or shut down. When the outer surface of the terminal body 401 near the bottom is rusted, the two pressing plates 406 are pressed simultaneously in the direction of the annular sleeve 402, and the corresponding ejector pin 412 is pushed to slide in the sealing ring 414, and at the same time, the multiple springs 413 are squeezed and contracted. As the pressing plate 406 moves, The end of the ejector pin 412 will be pushed to move from the sealing ring 414 to the inside of the annular plate 404, and then the annular solution capsule 405 will be punctured, and then the pressure on the pressing plate 406 will be released. Under the rebound of the spring 413, the pressing plate 406 will be pushed to reset, and then the ejector pin 412 will be driven to reset. Under the sealing effect of the sealing ring 414, the solution inside the annular solution capsule 405 can be prevented from leaking out. The annular solution capsule 405 contains acetic acid solution. After the annular solution capsule 405 is punctured, the acetic acid solution flows through the perforation to the inner wall of the annular plate 404, and then flows downward to the arc-shaped solution cover 415, and the acetic acid solution is discharged into the sponge cover 403 through a plurality of liquid flow pipes 411. The sponge cover 403 is in contact with the outer surface of the terminal body 401 near the bottom. , thereby coating the acetic acid solution on the outer surface of the terminal body 401 near the bottom, then waiting for a while, the acetic acid solution contains acidic components, and the acidic components destroy the structure of the iron oxide through a chemical reaction with the iron oxide in the rust stains, causing it to dissolve or convert into a scrapable substance, and then the hand-tightening nut 407 is rotated by the rotating knob on the top of the hand-tightening nut 407, driving the pad 408 to rotate, and at the same time driving the L-shaped block 417 embedded in the L-shaped groove 409 to rotate, further driving the annular sleeve 402 to rotate, so that the sponge sleeve 403 rotates on the outer surface of the terminal body 401 near the bottom, and the acetic acid solution is evenly coated on the outer surface of the terminal body 401 near the bottom, and as the sponge sleeve 403 rotates, the dissolved rust stains can be wiped off. The rust stains on the outer surface of the terminal body 401 are removed, and at the same time, the spiral scraper 410 scrapes off the rust stains on the outer surface of the terminal body 401. After the rust removal component 4 leaves the outer surface of the terminal body 401, the staff can use a cleaning cloth to wipe off the residual solution on the outer surface of the terminal body 401, or wait for it to dry naturally, so as to achieve the effect of rust removal. This solves the problem that when the grounding wire disassembly and assembly device of the power system substation is in use, the terminal used to connect the grounding wire will rust after long-term use, causing the surface of the terminal to become rough, increasing the contact resistance between the grounding wire and the terminal, and causing the discharge capacity of the grounding wire to decrease or become unstable. By holding the annular sleeve 402 and moving it, the L-shaped block 417 slides out of the L-shaped groove 409, and the annular sleeve 402 can be separated from the pad 408.Next, the two wiring holes at one end of the grounding wire are passed through the two terminal bodies 401 and dropped onto the gasket 9, and then the two hand-tightening nuts 407 are screwed onto the terminal body 401 again to install the grounding wire. By controlling the operation button on the switch 203, the second electric push rod 501 is started to pull the connecting plate 502 to move downward. With the support of the multi-section telescopic rod 503, the stability of the movement of the connecting plate 502 is improved. The outer surface of the current sensor 504 close to the bottom is embedded in the square hole 505. The movement of the connecting plate 502 drives the current sensor 504 to move downward, so that the sensing area at the bottom of the current sensor 504 contacts the terminal of the grounding wire. At this time, the second electric push rod 501 is automatically closed, and the inner movable sleeve of the insulating clamping plate 304 is arranged on the outer surface of the T-shaped slider 306. The structure of the T-shaped slider 306 matches the structure inside the insulating clamping plate 304. Then, hold the grounding rod 1 or the grip rod 7, and clamp the conductive block 305 on the grounding knife seat inside the transformer. Then start the first electric push rod 302 to push the insulating clamping plate 304 to slide on the outer surface of the T-shaped slider 306. Under the limiting action of the T-shaped slider 306, it is convenient to improve the stability of the movement of the insulating clamping plate 304. When the insulating clamping plate 304 is in close contact with the other side of the grounding knife seat in the transformer, the first electric push rod 302 is suspended, thereby installing the fixing component 3. Installed on the grounding knife seat, so that the conductive block 305 is in close contact with the grounding knife seat, the current is conducted to the terminal body 401 through the grounding knife seat, and then enters the grounding wire for discharge. At this time, the inductive part of the current sensor 504 will sense the change of the magnetic field, and then generate a signal output proportional to the current in the grounding wire, and transmit the current signal to the PLC controller 207 in the form of an electrical signal. The maximum and minimum working thresholds of the current are set in the PLC controller 207. The PLC controller 207 identifies and compares the received current signal. When the current value exceeds the maximum value, the PLC controller 207 will control the first prompt light 204 emits a red light, prompting the staff that the discharge is in progress. When the current value is lower than the minimum value, the PLC controller 207 will control the second prompt light 205 to emit a green light, prompting the staff that the discharge is about to end and they can prepare for the next step. This can help the staff see the discharge situation more accurately and be prepared. After connecting the grounding wire to the grounding knife seat in the transformer through the fixing component 3, turn the movable ring 601, and then pull the hook 604. Under the elastic force of the elastic band 602, the hook 604 can be hooked on the crossbar inside the transformer to provide auxiliary support for the grounding rod 1, improve stability, and prevent the grounding rod 1 from accidentally falling off, affecting the discharge work of the grounding wire.
[0034] Among them, the control switch 203, the first prompt light 204, the second prompt light 205, the battery 206, the first electric push rod 302, the second electric push rod 501, the current sensor 504 and the PLC controller 207 are all existing technologies, and their components and usage principles are all public technologies, so no excessive explanation is given here.
