Description

Technical Field

[0001] This utility model relates to a communication facility maintenance device, and more specifically, to a quick-installation and quick-disassembly electrolytic cell for electrolytic rust removal of anchor bolts. Background Technology

[0002] After long-term operation, some anchor bolts on steel towers will rust. Even with secondary pouring and encapsulation of the tower base with micro-expansion concrete after installation, some improper operations during actual construction can still cause the environment around the anchor bolts to become unstable and dry, ultimately leading to rust. Deep rust can cause tower collapse; therefore, rust removal is an important part of the daily maintenance of steel towers. In practice, mechanical rust removal methods are generally used. However, due to the confined space around the anchor bolts, using general-purpose rust removal machines creates blind spots and is difficult, increasing the risk of workplace accidents. Therefore, the method for removing rust from the anchor bolts of steel towers needs improvement. The invention patent with announcement number CN116397912A discloses a reinforcement structure for iron tower foundations and an iron tower. This invention can solve the problem of increased economic construction costs and resource waste caused by dismantling or scrapping the original tower foundation and rebuilding the tower foundation after the anchor bolts are corroded. However, this invention only makes up for the losses caused by the corrosion of the anchor bolts through structural optimization, and cannot actually prevent the corrosion of the anchor bolts. Utility Model Content

[0003] Existing mechanical rust removal methods for anchor bolts are limited by confined working spaces, resulting in incomplete rust removal, difficult construction, and safety issues. To overcome these shortcomings, this utility model provides a quick-installation and quick-disassembly electrolytic cell for electrolytic rust removal of anchor bolts. It can adapt to confined construction environments and achieve comprehensive, low-cost, and safe rust removal of anchor bolts.

[0004] The technical solution of this utility model is: a quick-assembly and quick-disassembly electrolytic cell for electrolytic rust removal of anchor bolts, comprising an upper and lower enclosure that are nested together, with a floor mat at the bottom of the lower enclosure. The upper and lower enclosures, along with the floor mat, form a cavity to contain the electrolyte. The nested upper and lower enclosures, plus the floor mat, create a relatively enclosed space for electrolytic rust removal of anchor bolts. This not only ensures that the electrolyte acts concentrated on the anchor bolts, improving the efficiency of rust removal, but also prevents the electrolyte from flowing everywhere, avoiding pollution to the surrounding environment. The upper and lower enclosures, together with the floor mat, quickly assemble the electrolytic cell; after rust removal, it can be easily disassembled for easy carrying and transportation, meeting the needs of quick-assembly and quick-disassembly electrolytic cells operating in different locations.

[0005] Preferably, the lower enclosure comprises two interlocking semi-cylinders connected by a snap-fit ​​structure. This design allows the lower enclosure to flexibly adapt to the distribution of anchor bolts of different diameters. Whether it's the relatively concentrated anchor bolts on small communication towers or the widely spaced anchor bolts on large towers, the fit can be adjusted by changing the interlocking position of the two semi-cylinders, thus improving the versatility of the electrolytic cell.

[0006] Preferably, the two semi-cylinders are connected by an elastic sheet on the outer circumference of the semi-cylinders. The elastic sheet ensures that the two semi-cylinders are always tightly connected, and even if bumps or vibrations occur during transportation or installation, the elastic sheet can play a stabilizing role, reducing the risk of electrolyte leakage due to loose connection.

[0007] Preferably, the semi-cylinder has an inlet on its top surface and an outlet on its inner circumference. The inlet on the top surface allows for easy and convenient injection of electrolyte from above, simplifying the process. Furthermore, the top-inlet design ensures the electrolyte is evenly distributed within the cavity under gravity, improving the electrolytic rust removal effect.

[0008] Preferably, the lower enclosure is equipped with multi-plate cathodes. Multiple cathodes create multiple cathode reaction zones in the electrolytic cell, allowing for a more uniform electrochemical reaction of the electrolyte around the anchor bolts, thus achieving comprehensive rust removal from anchor bolts in different locations. Compared to a single-plate cathode, multi-plate cathodes can cover a larger area, ensuring that all parts of the anchor bolts are in full contact with the electrolyte and undergo an electrolytic reaction, improving the comprehensiveness and thoroughness of rust removal.

[0009] Preferably, the upper enclosure is a rollable thin sheet. This rollable nature allows the upper enclosure to better adapt to the arrangement of anchor bolts in different shapes and spaces. During installation, workers can unfold and adjust the rollable upper enclosure according to the actual situation, ensuring it fits tightly against the lower enclosure and floor mat, forming a well-sealed cavity. This allows for successful installation even in confined or irregular spaces, improving the electrolytic cell's adaptability to complex environments.

[0010] Preferably, the floor mat is made of rubber. Rubber has good elasticity and sealing properties, and using rubber components in the floor mat 3 can effectively prevent electrolyte leakage from the bottom. The rubber floor mat can fit tightly against the ground, filling the tiny gaps between the ground and the lower enclosure, preventing electrolyte leakage to the ground and causing corrosion or pollution.

[0011] Preferably, the mat is ring-shaped with slits. The mat's shape matches the distribution of the anchor bolts, allowing it to surround the bolts and provide stable bottom support for the electrolyte. The slits facilitate fitting the mat over the anchor bolts without removing them from the foundation, greatly simplifying the installation process. Workers can directly slip the mat over the anchor bolts through the slits and adjust its position to fit the ground, improving installation convenience and efficiency.

[0012] The beneficial effects of this utility model are: It has strong adaptability to the working environment. This utility model can remove rust from anchor bolts by means of electrochemical reaction rather than mechanical movement, and is not limited by the size of the working environment, thus having strong adaptability.

[0013] The rust removal operation is highly efficient. This utility model uses fewer and lighter parts, making it easy to assemble and carry. Moreover, rust removal can be carried out simultaneously at multiple points and from all directions, thereby improving the efficiency of rust removal operations. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1: like Figures 1 to 4As shown, a quick-installation and quick-removal electrolytic cell for electrolytic rust removal of anchor bolts includes an upper enclosure 1, a lower enclosure 2, and a base mat 3. The upper enclosure 1 is adapted to fit outside the lower enclosure 2, forming a nested fit. The upper enclosure 1 is made of a rollable PVC sheet, and a silicone film is adhered to its inner circumference. The lower enclosure 2 and base mat 3 are made of 25-30mm thick soft rubber with a Shore hardness of 0. The lower enclosure 2 consists of two butt-joint semi-cylinders 201, which are made of rubber with a Shore hardness of 70-80. The two semi-cylinders 201 are connected by a snap-fit ​​structure, allowing the lower enclosure 2 to surround the anchor bolt 5, with the two ends of the two semi-cylinders 201 respectively butt-jointed. The anchor bolt 5 is installed on the mounting flange 8 at the bottom of the tower. The snap-fit ​​structure includes two protruding strips 206 and two recesses 207. Two protruding strips 206 and two recesses 207 are located at both ends of a semi-cylinder 201, and two recesses 207 are located at both ends of a semi-cylinder 201, with a one-to-one correspondence between the protruding strips 206 and the recesses 207. The cross-section of both the protruding strips 206 and the recesses 207 is semi-circular. The two semi-cylinders 201 are connected by the snap-fit ​​structure, which ensures a tight fit and prevents loosening during use. The snap-fit ​​structure can effectively withstand the pressure of the electrolyte and minor impacts from the outside, ensuring the sealing and structural stability of the lower enclosure, preventing electrolyte leakage, and guaranteeing the smooth progress of electrolytic rust removal.

[0021] Elastic sheets 202, made of PVC sheet, are bonded to the outer circumferential surfaces of the two semi-cylinders 201. Through the elastic sheets 202, one end of the two semi-cylinders 201 can be brought together, while the other end can be closed or separated, allowing the lower enclosure 2 to be rolled into a ring or extended to form a gap between the two semi-cylinders 201, thus avoiding the anchor bolts 5. An inlet 203 is provided on the top surface of the semi-cylinders 201, and an outlet 204 is provided on the inner circumferential surface of the semi-cylinders 201. The inlet 203 is connected to the outlet 204 through a channel inside the semi-cylinders 201. The inlet 203 is used to add electrolyte, and the outlet 204 is used to introduce the electrolyte into the enclosure area of ​​the lower enclosure 2. A semi-cylindrical tube 201 has a drain hole near its bottom, penetrating both its inner and outer circumferences. A drain pipe 6 is connected to the drain hole, and a switch valve is installed on the drain pipe 6. A drain pump 7 is connected to the end of the drain pipe 6. Multiple cathodes 205 are installed in electrode slots inside the lower enclosure 2. The multiple cathodes 205 can act simultaneously, increasing the active sites for electrochemical reactions and accelerating the dissolution rate of rust, thereby improving rust removal efficiency. In the same amount of time, multiple cathodes 205 can remove more rust than a single cathode, shortening the time required for rust removal, improving work efficiency, and meeting the needs of rapid and efficient rust removal in practical engineering. The ground mat 3 is annular and has radially slits 301. The bottom surface of the ground mat 3 contacts the surface of the tower's foundation 4, and the ground mat 3 sits on the bottom of the lower enclosure 2, forming a reliable seal. The upper enclosure 1, the lower enclosure 2, and the floor mat 3 together form an electrolytic cell with a cavity, which is used to contain the electrolyte.

[0022] When using a quick-release electrolytic cell for rust removal of anchor bolts, first, forcefully open the ground pad 3 at the slit 301 to expose a gap large enough for the anchor bolt 5 to pass through. Insert the anchor bolt 5 into this gap, and push the ground pad 3 to move it, allowing the anchor bolt 5 to enter the inner ring of the ground pad 3, ensuring the ground pad 3 fits tightly against the surface of the tower foundation 4. Then, join the two semi-cylinders 201 together, connecting them with a snap-fit ​​structure to form a closed lower enclosure 2, which is then placed around the anchor bolt 5. Next, unfold the upper enclosure 1 from its rolled-up state, wrapping it around the lower enclosure 2, forming a cavity to contain the electrolyte. Inject an appropriate amount of electrolyte into the cavity through the inlet 203, which is connected to an inlet pipe 9, with an inlet pump 10 connected to the end of the inlet pipe 9. The electrolyte used is a 10% sulfuric acid solution. Connect the power supply, using anchor bolt 5 as the anode and the multi-plate cathode 205 as the negative terminal, to start the electrolysis reaction. During electrolysis, closely observe the gas discharge from the electrolytic cell. After approximately 2 hours of electrolysis, turn off the power and drain the electrolyte through the drain hole. Remove the upper enclosure 1 and lower enclosure 2, and check the rust removal effect of anchor bolt 5.

[0023] Example 2: A quick-installation and quick-removal electrolytic cell for electrolytic rust removal of anchor bolts includes an upper enclosure 1, a lower enclosure 2, and a floor mat 3. The upper enclosure 1 is made of a rollable PVC sheet, and a silicone film is adhered to the inner circumference of the upper enclosure 1. The lower enclosure 2 and floor mat 3 are made of soft rubber with a Shore hardness of 0 degrees and a thickness of 25-30 mm. The lower enclosure 2 consists of two interlocking semi-cylinders 201 and an elastic sheet 202. The semi-cylinders 201 are made of rubber with a Shore hardness of 70-80 degrees. The two semi-cylinders 201 are connected by a snap-fit ​​structure, which allows the lower enclosure 2 to surround the anchor bolt 5, and the two ends of the two semi-cylinders 201 are interlocked. The anchor bolt 5 is installed on the mounting flange 8 at the bottom of the tower. The snap-fit ​​structure includes two protruding strips 206 and two recesses 207. Two protruding strips 206 and two recesses 207 are located at both ends of a semi-cylinder 201, and two recesses 207 are located at both ends of a semi-cylinder 201, with a one-to-one correspondence between the protruding strips 206 and the recesses 207. The cross-section of both the protruding strips 206 and the recesses 207 is semi-circular. The two semi-cylinders 201 are connected by the snap-fit ​​structure, which ensures a tight fit and prevents loosening during use. The snap-fit ​​structure can effectively withstand the pressure of the electrolyte and minor impacts from the outside, ensuring the sealing and structural stability of the lower enclosure, preventing electrolyte leakage, and guaranteeing the smooth progress of electrolytic rust removal. The elastic sheet 202 is bonded to the outer circumferential surface of the two semi-cylinders 201. The elastic sheet 202 is made of PVC sheet. Through the elastic sheet 202, one end of the two semi-cylinders 201 can approach each other, and the other end of the two semi-cylinders 201 can be brought together or separated, thereby causing the lower enclosure 2 to be rolled into a ring or stretched out to form a gap between the two semi-cylinders 201, thereby avoiding the anchor bolts 5.

[0024] The height of the elastic sheet 202 is greater than the height of the semi-cylinder 201. Unlike embodiment 1, in this embodiment, the elastic sheet 202 is adapted to fit outside the upper enclosure 1, so that the upper enclosure 1 and the lower enclosure 2 form a nested fit. A liquid inlet 203 is provided on the top surface of the semi-cylinder 201, and a liquid outlet 204 is provided on the inner circumferential surface of the semi-cylinder 201. The liquid inlet 203 is connected to the liquid outlet 204 through a channel inside the semi-cylinder 201. The liquid inlet 203 is used to add electrolyte, and the liquid outlet 204 is used to introduce electrolyte into the enclosed area of ​​the lower enclosure 2. Near the bottom of one semi-cylinder 201, a drain hole is provided, penetrating the inner and outer circumferential surfaces of the semi-cylinder 201. A drain pipe 6 is connected to the drain hole, and a switch valve is installed on the drain pipe 6. A drain pump 7 is connected to the end of the drain pipe 6. Multiple cathodes 205 are installed in electrode slots inside the lower enclosure 2. Multiple cathodes on the multi-plate cathode 205 can act simultaneously, increasing the active sites for electrochemical reactions and accelerating the dissolution rate of rust, thereby improving rust removal efficiency. In the same amount of time, the multi-plate cathode 205 can remove more rust than a single cathode, shortening the time required for rust removal, improving work efficiency, and meeting the needs of rapid and efficient rust removal in practical engineering. The ground mat 3 is annular and has radially slits 301. The bottom surface of the ground mat 3 contacts the surface of the tower foundation 4, and the ground mat 3 sits on the bottom of the lower enclosure 2, forming a reliable seal. The upper enclosure 1, lower enclosure 2, and ground mat 3 together form an electrolytic cell with a cavity, which is used to contain the electrolyte. The rest is the same as in Example 1.

[0025] When using a quick-release electrolytic cell for rust removal of anchor bolts, first, forcefully open the ground pad 3 at the slit 301 to expose a gap large enough for the anchor bolt 5 to pass through. Insert the anchor bolt 5 into this gap, and push the ground pad 3 to move it, allowing the anchor bolt 5 to enter the inner ring of the ground pad 3, ensuring the ground pad 3 fits tightly against the surface of the tower foundation 4. Then, join the two semi-cylinders 201 together, connecting them with a snap-fit ​​structure to form a closed lower enclosure 2, which is then placed around the anchor bolt 5. Next, unfold the upper enclosure 1 from its rolled-up state, wrapping it around the lower enclosure 2, forming a cavity to contain the electrolyte. Inject an appropriate amount of electrolyte into the cavity through the inlet 203, which is connected to an inlet pipe 9, with an inlet pump 10 connected to the end of the inlet pipe 9.

During electrolysis, closely observe the gas discharge from the electrolytic cell. After approximately 2 hours of electrolysis, turn off the power and drain the electrolyte through the drain hole. Remove the upper enclosure 1 and lower enclosure 2, and check the rust removal effect of anchor bolt 5.

The upper enclosure 1 is adapted to fit outside the lower enclosure 2, forming a nested fit.

The two semi-cylinders 201 are connected by a snap-fit ​​structure, allowing the lower enclosure 2 to surround the anchor bolt 5, with the two ends of the two semi-cylinders 201 respectively mated. The anchor bolt 5 is installed on the mounting flange 8 at the bottom of the tower. The convex-concave buckle structure includes two matching protrusions 206 and two grooves 207. Unlike Embodiment 1, in this embodiment, one protrusion 206 and one groove 207 are located at both ends of one semi-cylinder 201, and the other protrusion 206 and the other groove 207 are located at both ends of the other semi-cylinder 201. The positions of the protrusions 206 and grooves 207 correspond one-to-one. The cross-section of both the protrusions 206 and the grooves 207 is semi-circular. The two semi-cylinders 201 are connected by the convex-concave buckle structure. This connection method allows the two semi-cylinders to fit tightly together, preventing loosening during use.
