Description

Technical Field

[0001] This invention relates to the field of disassembly and assembly tools, and more particularly to an electrode disassembly device. Background Technology

[0002] The annealing process for silicon steel requires a sintering furnace; ignition electrodes (the shape of the ignition electrode is as follows) Figure 2 As shown, the electrode (hereinafter referred to as the electrode) is a consumable part on the sintering furnace nozzle. It is installed in the electrode mounting hole on the burner. Because it is long and usually multi-segmented, it is prone to breakage after long-term use under the influence of factors such as high temperature, vibration, thermal expansion and contraction, and oxidation. After breakage, it needs to be disassembled and replaced.

[0003] Because the electrode assembly area is small, most of the electrode is located inside the burner, and some parts may have been sintered, it is difficult to remove with conventional clamps. Generally, removal is quite difficult and may even require disassembling the burner to remove it completely, requiring a high level of operational skill. (If the electrode break is close to the opening of the electrode mounting hole and is only broken into two pieces, you can try to pull out the electrode fragments with tweezers or needle-nose pliers after disconnecting the ignition wire and removing half of the electrode. After cleaning the electrode mounting hole, install a new electrode. If the electrode break is far from the opening of the electrode mounting hole or is broken into multiple pieces, or even sintered, conventional clamps are ineffective. In this case, you need to use an endoscope to examine the electrode fragments and then gradually disassemble the burner, pushing the electrode fragments out from inside the burner.) The burner disassembly and assembly process is cumbersome, time-consuming, labor-intensive, and risky, and will seriously slow down the production schedule. In addition, frequent disassembly and assembly of the burner can also affect its service life and safety.

[0004] Therefore, there is a need for an electrode disassembly device that can efficiently remove broken ignition electrodes from sintering furnaces, is easy to use, and has comprehensive functions. Summary of the Invention

[0005] This application provides an electrode dismantling device that solves the technical problems in the prior art where, after the ignition electrode of a sintering furnace breaks, the removal process is difficult, inefficient, and risky due to limitations in installation location and structure, which can easily slow down the production process. The device achieves the technical effects of efficiently removing broken ignition electrodes from sintering furnaces, stably removing electrode fragments located in deep holes, being convenient to use, and having comprehensive functions.

[0006] This application provides an electrode removal device, including a functional tube and a restraint removal assembly;

[0007] The functional tube is a rigid straight tube. When in use, it is inserted into the gap between the hole wall of the electrode mounting hole and the electrode fragment, and the electrode fragment is fixed in conjunction with the binding and removal component.

[0008] The functional tube has holes near the bottom on its side wall for the restraint rope of the restraint removal assembly to pass through.

[0009] The binding and removal assembly is used to form a suitable-sized loop on the side wall of the functional tube near the bottom end by means of its own deformation, and to use the formed loop to lock and fix the electrode fragment in a timely manner in conjunction with the functional tube.

[0010] A side handle is positioned on the side wall of the functional tube for controlling the size of the loop formed by the restraint rope; when the side handle is rotated, the size of the loop formed by the restraint rope changes accordingly.

[0011] When disassembly is required, the functional tube and the restraint removal assembly work together to fix the electrode fragments and pull them out.

[0012] Furthermore, it also includes a base ring and a rod restraint assembly;

[0013] The base carrier ring is a rigid circular ring that serves as a load-bearing and supporting element, and the bottom is provided with a fixing body for mounting and fixing the base carrier ring on the electrode mounting hole.

[0014] The rod restraint assembly is used to restrict the movement of the functional tube, thereby facilitating the stable removal of the electrode fragment, so that after the functional tube fixes the electrode fragment, the electrode fragment can be easily pulled out along the axial direction of the electrode mounting hole.

[0015] The rod restraint assembly includes a vertical limiting tube and a connecting restraint rod group;

[0016] The vertical limiting tube is a rigid round tube with a length greater than 3 cm. Its axial direction is the same as that of the base ring. It is positioned on the base ring by connecting the binding rod group. The connecting binding rod group is composed of multiple rigid rods hinged together. The functional tube is coaxial with the vertical limiting tube, passes through it, and is slidably positioned on the vertical limiting tube.

[0017] Preferably, it also includes an air pump assembly;

[0018] The pump assembly is a combination of a pump and a valve, and is connected to the top of the functional tube through a flexible gas channel.

[0019] A gas heating component for heating gas is provided on the gas pump assembly or the gas passage;

[0020] The outer wall of the functional tube is equipped with a protective sleeve to prevent burns.

[0021] When faced with the situation where electrode fragments are sintered on the inner wall of the mounting hole, a functional tube is used in conjunction with a pump assembly and a gas heating assembly to output hot air to the sintering area to soften the sintering area, so that disassembly can be carried out.

[0022] Preferably, an illumination and camera assembly is also positioned on the side wall of the functional tube; the illumination and camera assembly is located near the bottom end of the functional tube and is more than 5 cm away from the bottom end of the functional tube, and is a combination of a miniature camera and an illumination lamp.

[0023] Preferably, the pumping assembly is connected to the internal space of the functional tube through two gas channels, one for blowing air and the other for sucking air. The gas channel for sucking air is equipped with a filter assembly, which is a filter element. When it is necessary to soften the sintering area, hot air is output through the functional tube. In other states, the functional tube is controlled to continuously suck air, which plays a role in dust removal.

[0024] Preferably, it also includes rotating parts;

[0025] The restraint rope is a strip-shaped rope, which is a cotton strip woven with metal wires. The metal wires are used to maintain the strength of the restraint rope and limit its elastic deformation.

[0026] The rotating component includes a housing, a motor and its transmission structure positioned inside the housing, and a rotating sleeve rotatably connected to the bottom of the housing;

[0027] The rotating sleeve is a tubular sleeve that is rotatably connected to the housing around its own axis, and a magnet is provided on its side wall; the top of the rotating sleeve is connected to the air inlet of the air pump assembly through a rotating sealing assembly.

[0028] The top of the functional tube is provided with a combination block that matches the rotating sleeve; the combination block is a rigid prismatic tube made of ferromagnetic material.

[0029] When cleaning is required, the loop formed by the binding rope is stretched and the functional tube carrying the binding rope is inserted into the electrode mounting hole; then the cleaning accessories and the assembly block are fixed together; while controlling the rotation of the rotating sleeve, the air pump assembly is controlled to draw in air and the functional tube is controlled to move axially along the electrode mounting hole; the strip-shaped binding rope beats and wipes the hole wall during rotation, cleaning it, and the cleaned dust is sucked away.

[0030] Preferably, auxiliary pipes and cleaning accessories are also included;

[0031] The auxiliary tube is a rigid straight round tube, one end of which is connected to an air outlet of the air pump assembly via a flexible hose;

[0032] The cleaning accessories include a fixed pipe, a base pipe, an outer pipe, a sealing pipe, and a nylon sheath;

[0033] The fixing tube is a rigid round tube with an annular groove on its side wall;

[0034] The base tube is a vertically placed rigid round tube, with its top fixed to the bottom of the fixed tube, the bottom closed, and a channel hole provided on the side wall;

[0035] The outer sleeve is an elastic tube made of rubber, which is sleeved and tightly attached to the base pipe and both ends are fixed to the outer wall of the base pipe.

[0036] The sealing tube is a rubber hose, fixed to the inner wall of the fixed tube, wider at the top and narrower at the bottom; when the bottom of the auxiliary tube touches the sealing tube and air is blown into the fixed tube, the sealing tube acts as a sealing gasket.

[0037] The nylon sheath is a mesh nylon tube that is fitted onto the combination of the fixing tube, the base tube, and the outer tube. During use, it is bound to the collar along with the fixing tube and deforms with the expansion and contraction of the outer tube to reduce wear on the outer tube. It also serves to clean the inner wall of the electrode mounting hole.

[0038] Preferably, the base tube also has a built-in unidirectional conductor;

[0039] The inner diameter of the small end of the closed tube is the same as or similar to the outer diameter of the auxiliary tube;

[0040] The one-way valve is made of silicone material.

[0041] Before using the collar on the functional tube to perform preliminary cleaning of the electrode mounting hole, the cleaning accessory is placed deep inside the electrode mounting hole, inflated by air, and then fixed in place. When cleaning the hole wall using the collar on the functional tube, the cleaning accessory will catch any dust and debris that are not sucked away. When the cleaning accessory is pulled out, it will brush the hole wall and push out the dust and debris at the same time.

[0042] Preferably, a guide rod is fixed to the bottom end of the auxiliary tube; the guide rod is a rigid rod that protrudes from the bottom of the auxiliary tube, is coaxial with the auxiliary tube, and has a diameter less than half of the inner diameter of the auxiliary tube.

[0043] Preferably, the cleaning accessory further includes an internal tube and an external sleeve;

[0044] The built-in tube has the same structure as the closed tube and is fixed to the inner wall of the base tube; the inner diameter of the small end of the built-in tube is also the same as or similar to the outer diameter of the auxiliary tube.

[0045] The unidirectional guide body is located below the built-in tube;

[0046] The outer sleeve is an elastic rubber tube that is fitted over the outer sleeve to completely cover the outer sleeve, and both ends are fixed to the outer side wall of the base tube; the upper half of the outer sleeve is densely covered with air holes.

[0047] The side wall of the base tube is also provided with a side vent; the side vent is located between the closed tube and the inner tube, and communicates with the space between the outer tube and the outer sleeve.

[0048] When it is necessary to drag and clean the accessories, insert the bottom end of the auxiliary tube between the closed tube and the inner tube, and blow air between the two; the air delivered to the space between the outer tube and the outer sleeve will be sprayed out from the air hole on the outer sleeve, blowing away the accumulated dust and debris while cleaning the hole wall.

[0049] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0050] By providing an electrode dismantling device with a rigid tube body having a rope loop near its end, electrode fragments can be dismantled. The rope loop allows for convenient and timely binding and fixing of the electrode fragments, as well as efficient and stable removal of the electrode fragments. This effectively solves the technical problems in the prior art where, after the ignition electrode of a sintering furnace breaks, the removal process is difficult, inefficient, and risky due to limitations in installation location and its own structure, which can easily slow down the production process. Thus, the electrode dismantling device can assist in the efficient removal of broken ignition electrodes from sintering furnaces, stably remove electrode fragments located in deep holes, and is convenient to use and has comprehensive functions.

[0074] Example 1

[0075] like Figure 1 As shown, the electrode disassembly device of this application is used to disassemble the remnant of electrode 001 located in the electrode mounting hole on the burner, and includes a base carrier ring 100, a rod restraint assembly, a functional tube 300, and a restraint removal assembly.

[0076] like Figure 3 and Figure 4 As shown, the base carrier ring 100 is a rigid circular ring that serves as a load-bearing support. The bottom is provided with a fixing body 110 for mounting and fixing the base carrier ring 100 onto the electrode mounting hole. The fixing body 110 is a threaded tube, a claw structure, an adsorption magnet, or a suction cup structure that is adapted to the electrode mounting hole. It is fixed at the opening of the electrode mounting hole during use.

[0077] The rod restraint assembly is used to restrict the movement of the functional tube 300, thereby facilitating the stable removal of the electrode fragment. After the functional tube 300 fixes the electrode fragment, it can easily pull the electrode fragment out along the axial direction of the electrode mounting hole, avoiding secondary breakage of the electrode fragment due to lateral force.

[0078] like Figure 1 As shown, the rod restraint assembly includes a vertical limiting tube 210 and a connecting restraint rod group 220;

[0079] The vertical limiting tube 210 is a rigid round tube with a length greater than 3 cm. Its axial direction is the same as that of the base ring 100. It is positioned on the base ring 100 by the connecting restraint rod assembly 220 and is supported by the connecting restraint rod assembly 220 to move arbitrarily in the space enclosed by the base ring 100. The connecting restraint rod assembly 220 is composed of multiple rigid rods hinged together and serves as a support. The functional tube 300 is coaxial with the vertical limiting tube 210, passes through it, and is slidably positioned on the vertical limiting tube 210. In use, the functional tube 300 moves relative to the vertical limiting tube 210 along the axial direction of the vertical limiting tube 210.

[0080] The connecting restraint rod assembly 220 includes a first rod body 221 and a second rod body 222;

[0081] Both the first rod 221 and the second rod 222 are rigid straight rods, and their length directions are perpendicular to the axial direction of the base ring 100. One end of the first rod 221 is rotatably connected to the surface of the base ring 100 away from the electrode mounting hole, and the axial direction of the rotation axis is the same as the axial direction of the base ring 100. One end of the second rod 222 is detachably fixed to the side wall of the vertical limiting tube 210 by means of a buckle, and the other end is hinged to the other end of the first rod 221. The axial direction of the rotation axis of the second rod 222 is also the same as the axial direction of the base ring 100. With the support and restriction of the first rod 221 and the second rod 222, the vertical limiting tube 210 can move flexibly in the space enclosed by the base ring 100 along a direction perpendicular to the axial direction of the base ring 100.

[0082] like Figure 4 and Figure 5 As shown, the functional tube 300 is a rigid straight tube that penetrates and slides on the vertical limiting tube 210. Its axial direction is the same as that of the vertical limiting tube 210. When in use, it is inserted into the gap between the hole wall of the electrode mounting hole and the electrode fragment and used with the binding and removal assembly to fix the electrode fragment.

[0083] The functional tube 300 has two side passage holes 310 near its top end on its side wall for the binding rope 410 of the restraint and dismantling assembly to pass through and exit, respectively; the functional tube 300 also has two near-bottom passage holes 320 near its bottom end on its side wall for the binding rope 410 of the restraint and dismantling assembly to pass through and exit, respectively; the two side passage holes 310 are arranged at different heights (the distances from the top end of the functional tube 300 are different); the two near-bottom passage holes 320 are at the same height; the functional tube 300 A side handle 330 is also positioned on the side wall; the side handle 330 is an oblique rigid rod or rigid plate, with the higher end hinged to the side wall of the functional tube 300, the hinge axis being perpendicular to the axial direction of the functional tube 300, and a torsion spring being provided at the hinge position; when the side handle 330 rotates, it changes the angle between itself and the functional tube 300; when the angle between the side handle 330 and the functional tube 300 decreases, the torsion spring accumulates elastic potential energy; the higher side passage hole 310 is provided close to the top of the hinge point of the side handle 330.

[0084] like Figure 4 and Figure 5 As shown, the restraint removal component is used to form a suitable-sized loop (rope loop) on the side wall of the functional tube 300 near the bottom end by deforming itself, and cooperates with the functional tube 300 to use the formed loop to timely lock and fix the electrode fragment.

[0085] The restraint removal assembly includes a restraint rope 410, a first drum 420, a second drum 430, and a rope pressing and fixing assembly;

[0086] The restraint rope 410 is a metal and / or non-metallic rope with a circular or rectangular cross-section, and its two ends are respectively wound and positioned on the first drum 420 and the second drum 430; both the first drum 420 and the second drum 430 are drum structures used for winding and releasing the restraint rope 410; the first drum 420 has a built-in ratchet mechanism that only releases the restraint rope 410 wound on it, without winding it up; the first drum 420 is positioned on the side wall of the functional tube 300 near the lower side passage hole 310; the second drum 430 is positioned at the end of the side handle 330 away from the functional tube 300; the rope pressing and fixing assembly Positioned on the side handle 330, it is used to restrict the movement of the restraint rope 410 by squeezing or by locking the rotation of the second drum 430 when under pressure; the restraint rope 410 passes through the lower side through hole 310, two near-bottom through holes 320, and the higher side through hole 310 in sequence; the restraint rope 410 near the higher side through hole 310 is close to the top surface of the side handle 330, and the restraint rope 410 near the second drum 430 is close to or close to the top surface of the side handle 330; when the side handle 330 is rotated, the tightness of the loop formed by the restraint rope 410 changes.

[0087] Preferred, such as Figure 4 and Figure 6 As shown, the rope fixing assembly is fixed to the top surface of the side handle 330, including a pressure plate 441, a pad strip 442, and a friction plate 443. The pressure plate 441 is an inclined rigid plate, parallel to the side handle 330. Two elastic rubber pad strips 442 are parallel to each other, with their lengths parallel to the length of the pressure plate 441, and are fixed to the bottom surface of the pressure plate 441 near both sides. The side of the pad strip 442 away from the pressure plate 441 is fixed to the top surface of the side handle 330. The pressure plate 441, pad strip 442, and the top surface of the side handle 330 together form a strip. The space; the friction plates 443 are rubber plates, two in number, located in the space enclosed by the pressure plate 441, the pad strip 442 and the side handle 330, respectively tightly attached to and fixed to the bottom surface of the pressure plate 441 and the top surface of the side handle 330; the restraint rope 410 passes through the pressure rope fixing assembly and passes between the two friction plates 443; when pressure is applied to the side handle 330 to make it rotate, it will overcome the elasticity of the pad strip 442, causing the two friction plates 443 to move closer to each other and squeeze the restraint rope 410, thereby fixing the restraint rope 410 and the side handle 330 together so that when the side handle 330 rotates, it will drive the loop formed by the restraint rope 410 to shrink.

[0088] Preferably, the rope-pressing fixing component is a manual pin positioned on the second drum 430. The rope-pressing fixing component can lock the rotation of the second drum 430 as needed (locking the rotation of the second drum 430 is equivalent to fixing the binding rope 410 to the side handle 330 together).

[0089] Preferably, the functional tube 300 is composed of multiple rigid straight tubes spliced ​​together.

[0090] Preferred, such as Figure 3 As shown, the electrode disassembly device of this application also includes a pump assembly 003; the pump assembly 003 is a combination of a pump and a valve, and is connected to the top of the functional tube 300 through a flexible gas channel (hose); a gas heating component for heating gas is provided on the pump assembly 003 or the flexible gas channel, preferably a metal heating wire; a protective sleeve for preventing burns is provided on the outer wall of the functional tube 300; when the electrode fragment is sintered on the inner wall of the mounting hole, the functional tube 300, in conjunction with the pump assembly 003 and the gas heating component, can output hot air to the sintering area to soften the sintering area (making it loose) so that the disassembly operation can be carried out; after softening the sintering area, the functional tube 300 can be used to easily move the electrode fragment so that the collar can fit and fix the electrode fragment, and it is not easy for the electrode fragment to break again under force.

[0091] Furthermore, an illumination camera assembly 340 is positioned on the side wall of the functional tube 300; the illumination camera assembly 340 is located near the bottom end of the functional tube 300 and is more than 5 cm away from the bottom end of the functional tube 300, and is a combination of a miniature camera and an illumination lamp, which is existing technology; a combination connector 350 is provided on the side wall of the functional tube 300 near the top; the combination connector 350 is connected to the illumination camera assembly 340 by signal (wired connection) and also connected to the display accessory 002 by signal (wired connection), and can be detached as needed; the display accessory 002 is a combination of a display and a control module, and the image acquired by the illumination camera assembly 340 can be observed through the display accessory 002, which is existing technology.

[0092] Preferably, the lighting camera assembly 340 is equipped with a dust cover that can be removed and installed as needed.

[0093] If the electrode removal device of this application does not include the illumination and imaging component 340, an endoscope is used to assist in the removal operation; if it does not include the air pump component 003 and the gas heating component, a hot air blower is used for heating; however, due to the inaccurate heating position, the heating effect is poor and it is more cumbersome and complicated to use.

[0094] Preferred, such as Figure 3As shown, the air pumping assembly 003 is connected to the internal space of the functional tube 300 through two gas channels, one for blowing air and the other for sucking air. A filter assembly 004 is provided on the gas channel used for sucking air. The filter assembly 004 is a filter element, which is existing technology. When it is necessary to soften the sintering area, hot air is output by the functional tube 300. In other states, the functional tube 300 is controlled to continuously suck air, which plays a role in dust removal, so that the lighting and imaging assembly 340 can stably obtain a clearer image.

[0095] Preferably, to avoid scalding, the gas heating component is located on the inner wall of the functional tube 300 near the bottom.

[0096] When the electrode removal device of this application embodiment is used:

[0097] First, disconnect the ignition wire from electrode 001, and then remove the half electrode fixed to the electrode mounting hole to expose the electrode mounting hole.

[0098] Observe the state of the electrode remnant inside the electrode mounting hole to determine whether sintering exists; if sintering exists, heat the sintered area to loosen it.

[0099] Fix the base carrier ring 100 on the electrode mounting hole (at this time, the functional tube 300 is positioned on the vertical limiting tube 210); adjust the size of the collar at the bottom of the functional tube 300 according to the internal space of the electrode mounting hole, and maintain the taut state of the binding rope 410 in other parts by coordinating the rotation of the first drum 420 and the second drum 430.

[0100] Insert the functional tube 300 into the electrode mounting hole, move the electrode fragment, and put the collar on the electrode fragment.

[0101] The restraint rope 410 is fixed to the side handle 330 using the rope fixing assembly. Rotating the side handle 330 tightens the collar and fixes the electrode fragment. The control function tube 300 is pulled out along the vertical limiting tube 210 (at this time, the vertical limiting tube 210 plays a guiding role, reducing the probability of secondary breakage of the electrode fragment).

[0102] Remove the fixed electrode fragment from the functional tube 300 (if it is inconvenient to remove, separate the vertical limiting tube 210 from the connecting restraint rod assembly 220); observe whether there are other fragments, and if so, continue to remove them;

[0103] After all the fragments are removed, use the loop formed by the binding rope 410 to bind the cloth or other cleaning tools to clean the inner oxide scale and carbon deposits in the electrode mounting hole.

[0104] Install new electrode 001.

[0105] Before using the electrode removal device to remove the electrode next time, observe the condition of the exposed restraint rope 410 (loop) to see if it needs to be replaced. If the wear is severe, control the rotation of the first drum 420 and the second drum 430 to replace the exposed restraint rope 410.

[0106] Preferably, a steel needle can be used to assist in the process of fitting the collar onto the electrode fragment.

[0107] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0108] This invention solves the technical problems in existing technologies where the removal of a broken ignition electrode from a sintering furnace is difficult, inefficient, and risky due to limitations in installation location and structure, and can easily slow down production. It achieves the technical benefits of an electrode disassembly device that can efficiently remove broken ignition electrodes from sintering furnaces, stably remove electrode fragments located in deep holes, and is convenient and feature-rich.

[0109] Example 2

[0110] Considering that the process of cleaning carbon deposits and oxide scale after disassembling electrode 001 is also quite tedious and time-consuming, in order to further improve the practicality and applicability of this application and improve the convenience of the operation process, this application embodiment has optimized and improved the structure of the functional tube 300 and the structure of the binding rope 410 based on the above embodiment, and added a rotating accessory, specifically:

[0111] like Figures 7 to 9 As shown, the combination connector 350 is detachable. After removal, it disconnects the wired connection with the display accessory 002 to prevent the presence of the information transmission line from affecting the rotation of the functional tube 300.

[0112] like Figure 10 As shown, the restraint rope 410 is a strip rope, which is a cotton strip woven with metal wires. The metal wires are used to maintain the strength of the restraint rope 410 and limit its elastic deformation.

[0113] The rotating component includes a housing 510, a motor and its transmission structure positioned inside the housing 510, and a rotating sleeve 520 rotatably connected to the bottom of the housing 510.

[0114] The housing 510 is a rectangular block, used to support other components of the rotating accessory and to facilitate gripping by operators;

[0115] The rotating sleeve 520 is a tubular sleeve that is rotatably connected to the housing 510 around its own axis, and a magnet is provided on its side wall; the top end of the rotating sleeve 520 is connected to the air inlet of the air pump assembly 003 through a rotating sealing assembly; the rotating sealing assembly is a rotating sealing joint, which is the prior art; the transmission structure is preferably a gear ring structure.

[0116] The top of the functional tube 300 is provided with a combination block 530 that matches the rotating sleeve 520; the combination block 530 is a rigid prismatic tube made of ferromagnetic material and can be attracted by a magnet.

[0117] When cleaning is required, the loop formed by the restraint rope 410 is stretched by hand; then the functional tube 300 carrying the restraint rope 410 is inserted into the electrode mounting hole; after that, the cleaning accessories and the assembly block 530 are assembled and fixed together; while controlling the rotation of the rotating sleeve 520, the air pump assembly 003 is controlled to draw in air and the functional tube 300 is simultaneously controlled to move axially along the electrode mounting hole; the strip-shaped restraint rope 410 beats and wipes the hole wall during rotation, cleaning it, and the cleaned dust is sucked away.

[0118] Preferably, the functional tube 300 is fitted with a sleeve for restraining the side handle 330. When the functional tube 300 needs to rotate, the side handle 330 is restrained, thereby reducing the shaking caused by uneven weight during the rotation of the functional tube 300.

[0119] Example 3

[0120] To achieve efficient and convenient cleaning of the electrode mounting holes, this embodiment adds an auxiliary tube 600 and cleaning accessories to the above embodiment; specifically:

[0121] like Figures 11 to 13 As shown, the auxiliary pipe 600 is a rigid straight round pipe, one end of which is connected to the air outlet of the air pump assembly 003 through a flexible hose.

[0122] The cleaning accessories include a fixed tube 710, a base tube 720, an outer tube 730, a sealing tube 740, and a nylon sheath;

[0123] The fixing tube 710 is a vertical rigid round tube with an annular groove on its side wall to facilitate the binding rope 410 to be looped around it.

[0124] The base tube 720 is a vertical rigid round tube, with its top fixed to the bottom of the fixed tube 710, its bottom closed, and its side wall provided with one or more ventilation holes 721.

[0125] The outer tube 730 is an elastic tube made of rubber, which is sleeved and tightly attached to the base tube 720 and both ends are fixed to the outer wall of the base tube 720; when the gas in the base tube 720 is output from the channel hole 721, it can inflate the outer tube 730.

[0126] The sealing tube 740 is a rubber hose, fixed to the inner wall of the fixed tube 710. It is larger at the top and smaller at the bottom. The inner diameter of the larger end is more than 1.3 times the diameter of the auxiliary tube 600, and the inner diameter of the smaller end is less than 0.8 times the diameter of the auxiliary tube 600. When the bottom of the auxiliary tube 600 contacts the sealing tube 740 and blows air into the fixed tube 710, its rubber material acts as a sealing gasket.

[0127] The nylon sheath is a mesh nylon tube that is fitted onto the combination of the fixing tube 710, the base tube 720, and the outer tube 730. In use, it is bound together with the fixing tube 710 to the collar formed by the binding rope 410 on the functional tube 300. It can deform with the expansion and contraction of the outer tube 730 to reduce the wear of the outer tube 730, and also serves to clean the inner wall of the electrode mounting hole.

[0128] In use, after initial cleaning of the electrode mounting hole using the collar on the functional tube 300, the cleaning accessory is fixed and inserted deep into the electrode mounting hole using the collar at the bottom of the functional tube 300. Then, the bottom end of the auxiliary tube 600 is inserted into the sealing tube 740 and pressed against the sealing tube 740. Air is blown into the cleaning accessory to make it expand and press against the inner wall of the electrode mounting hole. Then, the cleaning accessory is gradually pulled out or dragged back and forth using the functional tube 300 to clean the electrode mounting hole (when pulling out the cleaning accessory, the base carrier ring 100 needs to be removed together).

[0129] Preferably, both the outer tube 730 and the nylon sheath are replaceable.

[0130] Preferred, such as Figure 14 and Figure 15As shown, the base tube 720 also has a built-in one-way guide body 750; the inner diameter of the small end of the closed tube 740 is the same as or similar to the outer diameter of the auxiliary tube 600 (the difference is no more than 4 mm); the one-way guide body 750 is made of silicone and acts as a one-way valve, with the same structure as the anti-odor silicone core of the sewer. Under normal conditions, gas can only enter from the top of the one-way guide body 750 and exit from the bottom; before using the collar on the functional tube 300 to perform preliminary cleaning of the electrode mounting hole, the cleaning accessory can be placed deep in the electrode mounting hole, and after being blown in and expanded, it is fixed in the placement position. The auxiliary tube 600 will not cause the cleaning accessory to leak and shrink when it is removed from the cleaning accessory; after that, when using the collar on the functional tube 300 to clean the hole wall, the dust and debris that are cleaned off will be caught by the cleaning accessory even if they are not sucked away; finally, the cleaning accessory can be pulled out, and the dust and debris will be pushed out while the hole wall is being brushed (a hard rod can be inserted into the one-way guide body 750 through the push-out port to restore its original state).

[0131] Preferred, such as Figures 14 to 16 As shown, a guide rod 620 is also fixed at the bottom end of the auxiliary tube 600; the guide rod 620 is a rigid rod that protrudes from the bottom of the auxiliary tube 600, is coaxial with the auxiliary tube 600, and has a diameter less than half of the inner diameter of the auxiliary tube 600; when it is difficult to drag the cleaning accessory or when the cleaning accessory needs to be retracted, the guide rod 620 can be used to probe into the one-way ventilation body 750 to temporarily disable its one-way ventilation function.

[0132] To extend the service life of the components on the cleaning accessories, reduce their replacement frequency, and enhance the cleaning effect, preferably, such as Figure 17 and Figure 18As shown, the cleaning accessory also includes an internal tube 760 and an external sleeve 770; the internal tube 760 has the same structure as the closed tube 740 and is fixed to the inner wall of the base tube 720; the inner diameter of the small end of the internal tube 760 is the same as or similar to the outer diameter of the auxiliary tube 600; the unidirectional guide body 750 is located below the internal tube 760; the external sleeve 770 is an elastic rubber tube, which is fitted onto the outer sleeve 730, completely covering the outer sleeve 730, and its two ends are respectively fixed to the outer wall of the base tube 720; the upper half of the external sleeve 770 is densely covered with air holes; the base tube 720... Side air vents are also provided on the side wall; these side air vents are through holes that act as gas channels, located between the closed tube 740 and the inner tube 760, and communicating with the space between the outer tube 730 and the outer sleeve 770; when the cleaning accessory needs to be dragged, the bottom end of the auxiliary tube 600 is inserted between the closed tube 740 and the inner tube 760, and air is blown between them to control the auxiliary tube 600 and the functional tube 300 to move synchronously; the gas delivered to the space between the outer tube 730 and the outer sleeve 770 will be ejected from the air vents on the outer sleeve 770, blowing away accumulated dust and debris while cleaning the hole walls. During the dragging of the cleaning accessory, the expansion and contraction of the outer tube 730 can also be controlled as needed using the guide rod 620 in conjunction with the air outlet of the auxiliary tube 600.

[0133] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
