Description

Technical Field

[0001] The invention relates to a communication facility maintenance device, and more specifically, to an anchor bolt electrolytic rust removal device. Background Art

[0002] When the tower is in operation for more than 12 years, some anchor bolts will rust. The severity of the rust is related to the specific construction process. Originally, after the installation of the tower, after a stabilization period of 3-6 months, the tower foot would be cast and encapsulated with micro-expansive concrete to protect the anchor bolts and prevent the nuts from being stolen, forming a stable and relatively dry environment for the anchor bolt group. However, there are some irregular operations in the actual construction process, such as filling wet sand or bricks between the foundation and the formwork flange, and then encapsulating the surface with cement mortar, which eventually causes the anchor bolts to be in a complex and humid environment, which is prone to rust. If the rust develops deeply, it will cause the tower to collapse. Therefore, rust removal is an important part of the daily maintenance of the tower. In actual rust removal work, mechanical rust removal methods are generally used. However, due to the small space where the anchor bolts are located, and the installation distance between the positioning plate of the tower and the foundation varies depending on the terrain where the tower is located, general mechanical rust removal machines cannot meet the rust removal requirements. In addition, since the anchor bolts are generally arranged in a ring, the inner side close to the center of the tower base is not easy to grind, there is a grinding dead angle, and the construction is difficult, which is prone to work-related accidents. For this reason, the industry has introduced an electrolytic rust removal method. For example, the utility model patent with announcement number CN221117711U discloses a rust removal device for anchor bolts, but this device lacks lifting flexibility, is not convenient to install, and is difficult to adapt to working spaces of different heights. In addition, it is not easy to ensure the amount and concentration of the electrolyte. Summary of the invention

[0003] Some existing anchor bolt rust removal equipment is limited by a small working space and is difficult to construct; some lack flexibility and are difficult to adapt to working spaces at different heights. To overcome these defects, the present invention provides an anchor bolt electrolytic rust removal equipment that can be easily adjusted to have good adaptability to the working environment and efficiently implement anchor bolt rust removal.

[0004] The technical solution of the present invention is: a kind of anchor bolt electrolytic rust removal equipment, including a power supply and a modular adjustable electrolytic cell enclosure, the modular adjustable electrolytic cell enclosure forms a temporary electrolytic cell surrounding the anchor bolt, the temporary electrolytic cell is provided with an electrolyte, the power supply conducts the anchor bolt and the electrolyte in the temporary electrolytic cell respectively through a wire, and the modular electrolytic cell enclosure includes a semi-enclosed structure and a flexible wall electrolytic cell inner enclosure with adjustable height. The modular adjustable electrolytic cell enclosure is a modular structure, wherein the flexible wall electrolytic cell inner enclosure forms a semi-enclosed structure around the anchor bolt group, and then a closure is installed at the opening of the flexible wall electrolytic cell inner enclosure to complete the closure, and a fully enclosed compact temporary electrolytic cell is built on site around the anchor bolt to contain the electrolyte, so as to ensure that the local anchor bolt electrolytic rust removal equipment can use the electrolytic operation method to achieve the rust removal of the anchor bolt. The flexible wall electrolytic cell inner enclosure can adjust the height to adapt to the installation spacing between the positioning plate of the iron tower and the foundation. One power source can act on multiple electrolytic cells at the same time, improving the efficiency of rust removal. Since the local anchor bolt electrolytic rust removal equipment uses electrochemical reaction rather than mechanical movement to remove rust, it does not require a complex mechanical structure, and the weight of the electrolyte used is relatively smaller, which can reduce the amount of prepared materials to be carried, making it easier to carry and transport, and easier to reach the tower site built on inconvenient terrain, so it is more convenient to use.

[0005] Preferably, the modular adjustable electrolytic cell enclosure further comprises an electrolytic cell outer enclosure, which is located at the opening of the flexible-wall electrolytic cell inner enclosure and is combined with the flexible-wall electrolytic cell inner enclosure to form the enclosed temporary electrolytic cell. The electrolytic cell outer enclosure cooperates with the flexible-wall electrolytic cell inner enclosure to form a fully enclosed temporary electrolytic cell.

[0006] Preferably, the inner enclosure of the flexible-wall electrolytic cell comprises an upper bracket and a lower bracket, a scissor-type lifting arm is provided between the upper bracket and the lower bracket, and a flexible enclosure film is provided between the upper bracket and the lower bracket. The scissor-type lifting arm has a relatively large telescopic capacity, and the position of the upper bracket can be adjusted by the telescopic scissor-type lifting arm to achieve the function of changing the height to adapt to the distance between the positioning plate and the foundation. The flexible enclosure film enables the side enclosure of the inner enclosure of the flexible-wall electrolytic cell to have a sealing ability, ensuring that the temporary electrolytic cell can prevent the electrolyte from flowing out.

[0007] Preferably, the scissor-type lifting arm comprises a first arm and a second arm hinged to each other, the bottom end of the first arm is hinged to the lower bracket, and the top end is slidably connected to the upper bracket; the bottom end of the second arm is slidably connected to the lower bracket, and the top end is hinged to the upper bracket, and a ratchet mechanism is provided between the first arm and the second arm. The ratchet mechanism can generate a self-locking function of the scissor-type lifting arm, so that the inner enclosure of the flexible wall electrolytic cell maintains the adjusted height, and the lifting and lowering adjustment can be performed by releasing the self-locking.

[0008] Preferably, the device further comprises a gushing device, which comprises a liquid pump and a nozzle, and the nozzle is installed on the liquid pump. The nozzle is used to form a local higher liquid level, which overflows the nuts and washers at a higher position, and is beneficial to the rust removal of the nuts and washers. In addition, the circulation of the liquid pump can also prevent the local concentration of the electrolyte from being insufficient, thereby improving the stability of its electrochemical performance.

[0009] Preferably, the gushing device is arranged on the outer wall of the electrolytic cell. The outer wall of the electrolytic cell does not need to be adjusted in height, so there is no moving mechanism, which is convenient for providing installation support for the gushing device and can also reasonably utilize space.

[0010] Preferably, a tower cathode is also provided on the outer periphery of the electrolytic cell, which can greatly increase the conductive area, maintain the electrolysis current at a relatively large state, improve the electrolysis efficiency, and reduce the rust removal time.

[0011] Preferably, the power supply wire is electrically connected to the anchor bolt through an anchor bolt positive electric clamp, and the anchor bolt positive electric clamp includes a pair of curved clamp arms. The anchor bolt positive electric clamp is specially designed for clamping a large-sized large cylinder and can be firmly clamped on the anchor bolt to ensure that the power supply and the anchor bolt maintain a reliable electrical connection.

[0012] Preferably, the local anchor bolt electrolytic rust removal device also includes a dual-purpose bracket, which includes a power supply support part and a support leg, the support leg is connected to the bottom of the power supply support part, and the space between the bottom of the power supply support part and the support leg forms a power supply storage part. The dual-purpose bracket can be used for two people to carry the power supply when walking in the field, and can also be used as a power supply bracket to support and raise the power supply to enable better human-machine coordination, facilitate operation, and reduce labor intensity.

[0013] Preferably, the local anchor bolt electrolytic rust removal device further comprises a magnetic wire fixing buckle, which is arranged on the power supply and the modular adjustable electrolytic cell enclosure. The magnetic wire fixing buckle is used for temporary fixing of the wire to reduce accidental pulling of the wire.

[0014] The beneficial effects of the present invention are: The invention has good adaptability to the working environment. The inner enclosure of the flexible wall type electrolytic cell can be adjusted in height to adapt to the installation distance between the positioning plate of the iron tower and the foundation.

[0015] The rust removal operation efficiency is high. One power supply of the present invention can act on multiple electrolytic cells at the same time, thereby improving the rust removal operation efficiency.

[0016] Easy to use. Since the local anchor bolt electrolytic rust removal equipment uses electrochemical reaction rather than mechanical movement to remove rust, the weight of the electrolyte used is relatively smaller, which can reduce the amount of prepared materials to be carried, making it easier to carry and transport, and more convenient to use.

The scissor-type lifting arms 203 are located on the two sides of the upper bracket 201 and the lower bracket 202. The flexible enclosure 204 is sleeved on the upper bracket 201 and the lower bracket 202. The top of the upper bracket 201 and the bottom of the lower bracket 202 are both provided with silicone strips 2021. The upper bracket 201 and the lower bracket 202 are respectively provided with a slide groove, and the scissor-type lifting arm 203 includes a first arm 2031 and a second arm 2032.

A ratchet block 2034 is rotatably connected to the lower middle part of the second arm 2032. The rotating connection part of the ratchet block 2034 is provided with a torsion spring to make the ratchet block 2034 have a self-reset function. The lower ratchet 2033 and the ratchet block constitute a ratchet and ratchet mechanism. Under normal conditions, the ratchet 2033 and the ratchet block 2034 are engaged to lock the scissor-type lifting arm 203. The scissor-type lifting arm 203 can be unlocked by manually pushing the ratchet block 2034 away. The flexible surrounding film 204 is made of a thin cloth-based coating material, which is a flexible material with a thin layer of silicone on an elastic cloth surface, and has good bonding processability, waterproofness, high deformation, tear resistance, toughness, wear resistance, corrosion resistance and heat resistance and thermal conductivity. Thick EVA cushions are applied on both sides of the outer baffle 3 of the electrolytic cell.

[0029] The gushing device 4 includes a liquid pump 401 and a nozzle 402, and the nozzle 402 is installed on the liquid pump 401. The gushing device 4 is arranged on the outer enclosure 3 of the electrolytic cell. The tower cathode 5 is also integrated and installed in the outer enclosure 3 of the electrolytic cell to save the layout space. The positive electrode wire end is connected with the anchor bolt positive electric clamp 6, and the anchor bolt positive electric clamp 6 includes a pair of curved clamp arms 601, the middle and rear parts of the two clamp arms are hinged to each other, and the hinged parts of the two clamp arms are also provided with a top spring at a later position, and the two ends of the top spring are respectively abutted on the two clamp arms, and the inner side of the clamp arm is provided with anti-slip grooves. The anchor bolt positive electric clamp 6 is specially designed for clamping large cylinders, and the whole is made of copper material and can withstand a load of 60A. The anchor bolt positive electric clamp 6 is clamped on the anchor bolt 8, so that the power supply 1 is electrically connected to the anchor bolt 8. The power supply 1 and the modular adjustable electrolytic cell enclosure are provided with a magnetic wire fixing buckle, which is used for temporary fixing of the wire to reduce accidental pulling of the wire. The local anchor bolt electrolytic rust removal equipment also includes pig oil anti-seepage pads, which are silicone pads that can adapt to the electrolyte seepage prevention of rough cement surface tower bases with a roughness of 5 mm or less. The maximum leakage does not exceed 10 ml per minute. It can block the rough cement surface while ensuring appropriate strength, and a 0.1mm 5-degree silicone film is compounded on its surface to solve the problem of excessive stickiness on the low-hardness silicone surface.

[0030] When using local anchor bolt electrolytic derusting equipment to perform anchor bolt derusting operations, first clean the foundation 10 around the anchor bolt 8, prepare ten pig oil-type anti-seepage pads, and dig a through hole that matches the maximum diameter of the anchor bolt 8 in the non-edge area of ​​each pad. After aligning the through hole with the anchor bolt 8, vertically lower the pig oil-type anti-seepage pad, and the anchor bolt 8 passes through the through hole, so that each pig oil-type anti-seepage pad forms a working area around each anchor bolt 8. Prepare ten flexible-walled electrolytic cell inner enclosures 2, corresponding one to one with the ten anchor bolts of the tower foot. According to the installation spacing between the positioning plate 9 of the tower and the foundation 10, push the scissor-type lifting arm 203 by hand to make the position of the upper bracket 201 lower than the positioning plate, and obtain a suitable height of the flexible-walled electrolytic cell inner enclosure 2, which can enter between the positioning plate 9 of the tower and the foundation 10. The U-shaped opening of the flexible-wall electrolytic cell inner enclosure 2 is facing outward, gradually approaching the anchor bolt 8, until the anchor bolt 8 enters the U-shaped opening of the flexible-wall electrolytic cell inner enclosure 2, at which time the flexible-wall electrolytic cell inner enclosure 2 forms a semi-enclosure around the anchor bolt 8. Then the upper bracket 201 is lifted as high as possible by the scissor-type lifting arm 203, so that the upper bracket 201 is against the positioning plate 9 of the iron tower, and pressure is generated between the flexible-wall electrolytic cell inner enclosure 2 and the positioning plate 9, and the silicone strips 2021 on the upper bracket 201 and the lower bracket 202 respectively press the positioning plate and the pig oil type anti-seepage pad to produce a sealing effect. The inner side of the flexible enclosure 204 is pulled upward to make it as flat and wrinkle-free as possible, and then the electrolytic cell outer baffle 3 is installed as a closure at the U-shaped mouth of the flexible wall electrolytic cell inner enclosure 2, and a flat steel sheet is inserted between the flexible enclosure 204 and the side of the electrolytic cell outer baffle 3. The flat steel sheet and the flexible enclosure 204 and the side of the electrolytic cell outer baffle 3 are matched with each other to form a seal between the flat steel sheet, the flexible enclosure 204, and the side of the electrolytic cell outer baffle 3. If necessary, the contact part between the flat steel sheet and the flexible enclosure 204 can also be bonded with an adhesive sealing strip, and the deadweight of the electrolytic cell outer baffle 3 can cause the pig fat type anti-seepage pad to produce elastic deformation, forming a seal with the bottom of the electrolytic cell outer baffle 3. Finally, after the flexible wall electrolytic cell inner enclosure 2 and the electrolytic cell outer baffle 3 are assembled and installed, a fully enclosed compact temporary electrolytic cell is built on site around the anchor screw 8. When the temporary electrolytic cell is built, the outer end of the temporary electrolytic cell is made to extend beyond the positioning plate so that the gas generated by electrolysis can be discharged smoothly. Electrolyte is injected into the temporary electrolytic cell, and the power supply 1 is connected with the anchor bolts, the tower cathode 5 and the liquid pump 401 to complete the electrical connection. The distance between the anchor bolts and the tower cathode 5 is controlled between 50-100mm to ensure that the current intensity of 5-10A is maintained in the electrolyte during electrolysis, to ensure the rust removal speed and reduce the working time.

The lower ratchet 2033 and the ratchet block constitute a ratchet and ratchet mechanism. Under normal conditions, the ratchet 2033 and the ratchet block 2034 are engaged to lock the scissor-type lifting arm 203; the ratchet block 2034 can be unlocked by manually pushing away the ratchet block 2034.

[0034] When using local anchor bolt electrolytic derusting equipment to perform anchor bolt derusting operations, first clean the ground around the anchor bolts, prepare ten pig oil-type anti-seepage pads, and dig a through hole matching the maximum diameter of the anchor bolt in the non-edge area of ​​each pad. Align the through hole with the anchor bolt and then vertically lower the pig oil-type anti-seepage pad. The anchor bolt passes through the through hole, so that each pig oil-type anti-seepage pad forms an operating area around each anchor bolt. Prepare twenty flexible wall electrolytic cell inner enclosures 2, two in a group, corresponding to the ten anchor bolts of the tower foot. The two flexible-walled electrolytic cell enclosures 2 in each group are divided into inner and outer positions. The inner flexible-walled electrolytic cell enclosure 2 is installed first. According to the installation spacing between the positioning plate 9 of the iron tower and the foundation 10, the scissor-type lifting arm 203 of the inner flexible-walled electrolytic cell enclosure 2 is manually pushed to make the position of the upper bracket 201 lower than the positioning plate, so as to obtain a suitable height of the flexible-walled electrolytic cell enclosure 2, which can enter between the positioning plate and the foundation of the iron tower.

Then, the upper bracket 201 is lifted as high as possible by the scissor-type lifting arm 203, so that the upper bracket 201 is against the positioning plate of the iron tower, and pressure is generated between the flexible-walled electrolytic cell inner enclosure 2 and the positioning plate 9, and the silicone strips 2021 on the upper bracket 201 and the lower bracket 202 respectively press the positioning plate 9 and the pig oil-type anti-seepage pad to produce a sealing effect. Then, the outer flexible-walled electrolytic cell inner enclosure 2 is used as a closure member to dock with the inner flexible-walled electrolytic cell inner enclosure 2, and the height of the outer flexible-walled electrolytic cell inner enclosure 2 is adjusted to the same height as the inner flexible-walled electrolytic cell inner enclosure 2 by the scissor-type lifting arm 203, and a heavy object is loaded on the outer flexible-walled electrolytic cell inner enclosure 2. The total weight of the outer flexible-walled electrolytic cell inner enclosure 2 can cause the pig oil-type anti-seepage pad to produce elastic deformation, and also form a seal with the bottom of the lower bracket 202 of the outer flexible-walled electrolytic cell inner enclosure 2. The flexible enclosure 204 of the inner and outer flexible-wall electrolytic cell enclosure 2 is bonded with adhesive sealing strips, so that the joints between the flexible enclosure 204 are covered and sealed, and the sides of the outer enclosure 3 of the electrolytic cell are sealed. Finally, after the inner and outer flexible-wall electrolytic cell enclosures 2 are assembled and installed, a fully enclosed compact temporary electrolytic cell is built on site around the anchor bolts. When the temporary electrolytic cell is built, the gas generated by electrolysis can be discharged smoothly because the outer end of the temporary electrolytic cell exceeds the positioning plate. Electrolyte is injected into the temporary electrolytic cell, and the power supply 1 is connected with the anchor bolts, the tower cathode 5 and the liquid pump 401 to complete the electrical connection. The distance between the anchor bolts and the tower cathode 5 is controlled between 50-100mm to ensure that the current intensity of 5-10A is maintained in the electrolyte during electrolysis, to ensure the rust removal speed and reduce the working time.

Each channel can be set for voltage, current, operation time, and voltage and current limiting. The voltage and current limiting parameter values ​​are generally fixed to 33V and 11A. In addition, there is a 24V power supply inside the power supply 1 for control and communication interaction. The dual-purpose bracket 7 is formed by bending a rectangular metal frame, and the overall shape is U-shaped, wherein the parts constituting the two sides of the U-shape constitute the support legs 702, the U-shaped bottom constitutes the power storage part 703, and the reverse side of the U-shaped bottom constitutes the power support part 701. The dual-purpose bracket 7 has two functions of "lifting" and "working". When the U-shaped mouth faces upward, the dual-purpose bracket 7 is in the "lifting" state, the power supply 1 is placed in the power storage part 703, and the support legs 702 can be used as a handle to be carried by two operators; when the dual-purpose bracket 7 is in the "working" state, the dual-purpose bracket 7 is turned upside down and used as a support platform for the power supply 1, the support legs 702 are supported on the ground, and the power support part 701 is used to support the power supply 1.

[0036] Different from Example 1, the modular adjustable electrolytic cell enclosure described in this embodiment includes a pair of flexible-walled electrolytic cell inner enclosures 2, which are semi-enclosed structures, semicircular as a whole, and adjustable in height. The openings of the two flexible-walled electrolytic cell inner enclosures 2 are opposite to each other, and are combined into the closed temporary electrolytic cell. The flexible-walled electrolytic cell inner enclosure 2 includes an upper bracket 201, a lower bracket 202, and a flexible enclosure 204. Three screws are arranged between the upper bracket 201 and the lower bracket 202. The upper bracket 201 and the lower bracket 202 are both semicircular. The bottom end of the screw is fixed to the lower bracket 202, and the three screws are respectively located at the two end points and the midpoint of the semicircular arc of the lower bracket 202. The two end points and the midpoint of the semicircular arc of the upper bracket 201 are respectively provided with through holes. The screw passes through the through holes on the upper bracket 201. Two nuts are arranged on each screw, and the nuts are one above and one below, sandwiching the upper bracket 201 in the middle. The flexible membrane 204 is sleeved on the upper bracket 201 and the lower bracket 202, and the screw is located outside the flexible membrane 204. Silicone strips 2021 are provided on the top of the upper bracket 201 and the bottom of the lower bracket 202. The flexible membrane 204 is made of a thin cloth-based film material, which is a flexible material with a thin layer of silicone compounded on an elastic cloth surface, and has good bonding processability, waterproofness, high deformation, tear resistance, toughness, wear resistance, corrosion resistance, and heat resistance and thermal conductivity.

[0037] The gushing device 4 includes a liquid pump 401 and a nozzle 402, and the nozzle 402 is installed on the liquid pump 401. The gushing device 4 and the tower cathode 5 are both placed in the temporary electrolytic cell. The end of the positive electrode wire is connected to the anchor bolt positive electric clamp 6, and the anchor bolt positive electric clamp 6 includes a pair of curved clamp arms 601, and the middle and rear parts of the two clamp arms are hinged to each other. A top spring is also provided at a later position of the hinge part of the two clamp arms, and the two ends of the top spring are respectively abutted on the two clamp arms, and the inner side of the clamp arm is provided with anti-slip grooves. The anchor bolt positive electric clamp 6 is specially designed for clamping large cylinders, and the whole is made of copper material and can withstand a load of 60A. The anchor bolt positive electric clamp 6 is clamped on the anchor bolt 8 to electrically connect the power supply 1 to the anchor bolt 8. The power supply 1 and the modular adjustable electrolytic cell enclosure are provided with a magnetic wire fixing buckle, which is used for temporary fixing of the wire to reduce accidental pulling of the wire. The local anchor bolt electrolytic rust removal equipment also includes a pig oil type anti-seepage pad, which is a silicone pad that can adapt to the electrolyte anti-seepage of the rough cement surface tower base with a roughness of 5 mm or less, and the maximum leakage does not exceed 10 ml per minute. It can block the rough cement surface and ensure appropriate strength at the same time, and a 0.1mm 5-degree silicone film is compounded on its surface to solve the problem of excessive viscosity of the low-hardness silicone surface. The rest is the same as Example 1.

[0038] When using local anchor bolt electrolytic derusting equipment to perform anchor bolt derusting operations, first clean the ground around the anchor bolts, prepare ten pig oil-type anti-seepage pads, and dig a through hole matching the maximum diameter of the anchor bolt in the non-edge area of ​​each pad. Align the through hole with the anchor bolt and then vertically lower the pig oil-type anti-seepage pad. The anchor bolt passes through the through hole, so that each pig oil-type anti-seepage pad forms an operating area around each anchor bolt. Prepare twenty flexible wall electrolytic cell inner enclosures 2, two in a group, corresponding to the ten anchor bolts of the tower foot. The two flexible-walled electrolytic cell inner enclosures 2 in each group are divided into inner and outer positions. The inner flexible-walled electrolytic cell inner enclosure 2 is installed first. According to the installation spacing between the positioning plate 9 of the iron tower and the foundation 10, the scissor-type lifting arm 203 of the inner flexible-walled electrolytic cell inner enclosure 2 is manually pushed to make the position of the upper bracket 201 lower than the positioning plate, so as to obtain a suitable height of the flexible-walled electrolytic cell inner enclosure 2, which can enter between the positioning plate of the iron tower and the foundation. The opening of the flexible-walled electrolytic cell inner enclosure 2 is facing outward, gradually approaching the anchor bolt until the anchor bolt enters the opening of the flexible-walled electrolytic cell inner enclosure 2. At this time, the flexible-walled electrolytic cell inner enclosure 2 forms a semi-enclosure around the anchor bolt group, and the opening end of the flexible-walled electrolytic cell inner enclosure 2 exceeds the outer edge of the positioning plate 9. Then, by adjusting the nut, the upper bracket 201 is raised as high as possible, so that the upper bracket 201 is against the positioning plate of the iron tower, and pressure is generated between the inner enclosure 2 of the flexible-walled electrolytic cell and the positioning plate 9. The silicone strips 2021 on the upper bracket 201 and the lower bracket 202 respectively press the positioning plate 9 and the pig oil-type anti-seepage pad to produce a sealing effect. Then, the outer flexible-walled electrolytic cell inner enclosure 2 is used as a closure to be docked with the inner flexible-walled electrolytic cell inner enclosure 2, and the height of the outer flexible-walled electrolytic cell inner enclosure 2 is adjusted to the same height as the inner flexible-walled electrolytic cell inner enclosure 2 by adjusting the nut. A heavy object is loaded on the outer flexible-walled electrolytic cell inner enclosure 2. The total weight of the outer flexible-walled electrolytic cell inner enclosure 2 can cause the pig oil-type anti-seepage pad to produce elastic deformation, and also form a seal with the bottom of the lower bracket 202 of the outer flexible-walled electrolytic cell inner enclosure 2. The flexible enclosure 204 of the inner and outer flexible-wall electrolytic cell enclosure 2 is bonded with adhesive sealing strips, so that the joints between the flexible enclosure 204 are covered and sealed, and the sides of the outer enclosure 3 of the electrolytic cell are sealed. Finally, after the inner and outer flexible-wall electrolytic cell enclosures 2 are assembled and installed, a fully enclosed compact temporary electrolytic cell is built on site around the anchor bolts. When the temporary electrolytic cell is built, the gas generated by electrolysis can be discharged smoothly because the outer end of the temporary electrolytic cell exceeds the positioning plate. Electrolyte is injected into the temporary electrolytic cell, and the power supply 1 is connected with the anchor bolts, the tower cathode 5 and the liquid pump 401 to complete the electrical connection. The distance between the anchor bolts and the tower cathode 5 is controlled between 50-100mm to ensure that the current intensity of 5-10A is maintained in the electrolyte during electrolysis, to ensure the rust removal speed and reduce the working time.
