Abstract
Description
Technical Field
[0001] The present application relates to the technical field of galvanized pipe repair, and particularly to a repair device for the galvanized layer of galvanized pipes. Background Art
[0002] Currently, for the installation of galvanized pipes, in special cases, it is necessary to weld and fix the galvanized pipes. After long-term use of the fixed galvanized pipes, since the galvanized layer on the galvanized pipes is directly exposed to the air, the situation where part of the galvanized layer is corroded easily occurs. Therefore, for the above situation, the existing repair methods generally include two types: one is to directly brush a layer of anti-rust paint on the corroded part of the galvanized pipe, so as to avoid the corroded part of the galvanized pipe affecting the overall use of the galvanized pipe; the other is to directly disassemble the entire section of the galvanized pipe and return it to the factory for galvanized layer repair.
[0003] However, in actual use, when using the above method of brushing anti-rust paint to repair the corroded part of the galvanized pipe, due to the insignificant anti-corrosion performance of the anti-rust paint, the anti-corrosion performance of the galvanized pipe still cannot be guaranteed during long-term use, thus affecting the overall service life of the galvanized pipe. And when using the method of disassembling the entire galvanized pipe and returning it to the factory for repair, since the galvanized pipe is fixed, the overall disassembly process is relatively difficult and not conducive to use. Utility Model Content
[0004] In order to achieve the purpose of conveniently and quickly repairing galvanized pipes and ensuring their anti-corrosion performance after repair, the present application provides a repair device for the galvanized layer of galvanized pipes.
[0005] A repair device for the galvanized layer of galvanized pipes provided by the present application adopts the following technical solutions:
[0006] A repair device for the galvanized layer of galvanized pipes includes a rectifying mechanism for energizing and adjusting the current and an adsorption cotton for adsorbing and locking the electro-galvanizing solution. The rectifying mechanism is provided with a positive electrode and a negative electrode. A zinc mesh is arranged inside the adsorption cotton. A first wire is arranged on the rectifying mechanism. The zinc mesh is electrically connected to the positive electrode of the rectifying mechanism through the first wire. The negative electrode of the rectifying mechanism is electrically connected to the galvanized pipe.
[0007] By adopting the above technical solution, during actual operation, first immerse the adsorption cotton with a zinc mesh inside in the electro-galvanizing solution for a period of time and then take it out. The adsorption cotton adsorbs and locks the electro-galvanizing solution. Then wrap the adsorption cotton with the attached electro-galvanizing solution around the place where the galvanized layer needs to be repaired, and electrically connect the zinc mesh with the rectifying mechanism through the first wire. Connect the negative pole of the rectifying mechanism with the galvanized pipe. After that, energize the rectifying mechanism and adjust it to an appropriate current magnitude, and galvanizing treatment can be achieved at the place where the galvanized layer needs to be repaired. During the electroplating process, use the zinc mesh electrically connected to the positive pole of the rectifying mechanism as the anode, and use the galvanized pipe electrically connected to the negative pole of the rectifying mechanism as the cathode. The whole device provides electro-galvanizing solution and anode zinc for repairing the galvanized layer of the pipe, so as to achieve the purpose of repairing the damaged galvanized layer on the fixed galvanized pipe, thereby ensuring the anti-corrosion performance of the repaired galvanized pipe.
[0008] Preferably, the zinc mesh is horizontally arranged, and the distance between the upper surface of the zinc mesh and the upper surface of the adsorption cotton is less than the distance between the lower surface of the zinc mesh and the lower surface of the adsorption cotton.
[0009] By adopting the above technical solution, due to the different distances from the upper and lower surfaces of the zinc mesh to the adsorption cotton, it enables the staff to control the distance from the zinc mesh to the galvanized pipe by flipping the adsorption cotton according to the needs of the repair area of the galvanized pipe, thereby controlling the magnitude of the current, so as to achieve the effect of optimizing electroplating.
[0010] Preferably, both ends of the adsorption cotton are bent towards each other to form a repair sleeve for wrapping around the galvanized pipe, and the repair sleeve can be bent along its own length direction.
[0011] By adopting the above technical solution, by using the setting that the adsorption cotton can be bent into a repair sleeve, the adsorption cotton can perform on-site repair of the galvanized layer at the abnormal-shaped parts of the galvanized pipe, such as elbows, reducers, etc., so as to effectively electroplate and repair the galvanized pipe, improving the adaptability and practicality of the electroplating device.
[0012] Preferably, an insulating layer is provided at the connection between the zinc mesh and the first wire.
[0013] By adopting the above technical solution, the connection between the zinc mesh and the first wire is insulated by the insulating layer, thereby effectively preventing current leakage at the connection between the zinc mesh and the first wire, protecting the safety of the operator and the device, and at the same time preventing the zinc mesh from being consumed as an anode during electroplating.
[0014] Preferably, the rectifying mechanism includes a rectifier, a strong magnetic ironing device and a second wire. The positive and negative poles on the rectifying mechanism are both arranged on the rectifier. One end of the strong magnetic ironing device is electrically connected to the negative pole of the rectifier through the second wire, and the other end of the strong magnetic ironing device is electrically connected to the galvanized pipe.
[0015] By adopting the above technical solution, one end of the strong magnetic iron remover is electrically connected to the negative electrode of the rectifier, and the other end of the strong magnetic iron remover is electrically connected to the galvanized pipe, thereby ensuring the integrity and stability of the current loop.
[0016] Preferably, a bundling member for bundling the adsorption cotton on the galvanized pipe is provided on the adsorption cotton.
[0017] By adopting the above technical solution, by means of the arrangement of the bundling member, the adsorption cotton is bundled on the galvanized pipe, thereby ensuring the connection stability of the adsorption cotton during the electroplating process.
[0018] Preferably, the bundling member is set as a cable tie.
[0019] By adopting the above technical solution, by means of the arrangement of the cable tie, it is convenient for the staff to perform anti-loosening operation on the adsorption cotton, thereby improving the stability of the adsorption cotton wrapped around the galvanized layer to be repaired.
[0020] Preferably, the adsorption cotton is set as polyester fiber cotton.
[0021] By adopting the above technical solution, since the adsorption cotton is made of polyester fiber cotton material, the polyester fiber cotton has good liquid absorption and air permeability, can form a stable electrolyte environment, and is beneficial to the progress of the electroplating reaction; at the same time, the polyester fiber cotton has high corrosion resistance and can extend the service life of the device.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. During actual operation, the adsorption cotton with a zinc mesh inside is immersed in the electro-galvanizing solution for a period of time and then taken out. The electro-galvanizing solution is adsorbed and locked by the adsorption cotton, and then the adsorption cotton with the zinc mesh is wrapped around the galvanized layer to be repaired. The zinc mesh electrically connected to the positive electrode of the rectifying mechanism is used as the anode, and the galvanized pipe electrically connected to the negative electrode of the rectifying mechanism is used as the cathode. By energizing the rectifying mechanism and adjusting to an appropriate current magnitude, galvanizing treatment can be achieved at the galvanized layer to be repaired on the fixed galvanized pipe, thereby ensuring the anti-corrosion performance of the repaired galvanized pipe;
[0024] 2. Due to the different distances from the upper and lower surfaces of the zinc mesh to the adsorption cotton, the staff can control the distance from the zinc mesh to the galvanized pipe by flipping the adsorption cotton according to the needs of the repair area of the galvanized pipe, so as to control the magnitude of the current, thereby achieving the effect of optimizing electroplating;
[0025] 3. By means of the arrangement of the cable tie, it is convenient to install and disassemble, and the operation is simple. At the same time, it is ensured that the electroplating device will not loosen or fall off due to the pipe shape, vibration or other external factors during the electroplating process, which not only ensures the stability of the electroplating effect but also improves the safety of the entire electroplating process.

Detailed implementation manners
[0030] The following will further describe the present application in detail with reference to the attached Figure 1 - attached Figure 3 drawings.
[0031] The embodiment of the present application discloses a repair device for the galvanized layer of a galvanized pipe.
[0032] Referring to Figure 1 , a repair device for the galvanized layer of a galvanized pipe includes an adsorption cotton 1 for adsorbing and locking the electro-galvanizing solution and a rectifying mechanism 2 for energizing and adjusting the current.
[0033] Referring to Figure 2 , in the embodiment of the present application, the adsorption cotton 1 is preferably set as a polyester fiber cotton 11 with a thickness of 3 - 5 cm. The polyester fiber cotton 11 has good liquid absorption and air permeability. The polyester fiber cotton 11 is immersed in the electro-galvanizing solution, and the electro-galvanizing solution is locked by the polyester fiber cotton 11, so that a stable electrolyte environment can be formed by the polyester fiber cotton 11 during electroplating, which is beneficial to the progress of the electroplating reaction. A zinc mesh 3 is arranged in the polyester fiber cotton 11. The zinc mesh 3 is placed between two formed polyester fiber cottons 11, and then the zinc mesh 3 is densely sewn to the upper and lower polyester fiber cottons 11 with a nylon rope.
[0034] Referring to Figure 1 and Figure 2, before the rectifying mechanism 2 is electrified, the polyester fiber cotton 11 needs to be completely immersed in the electro-galvanizing solution. In this embodiment, the electro-galvanizing solution can adopt an acidic potassium chloride galvanizing solution. Since the polyester fiber cotton 11 has good adsorption, the polyester fiber cotton 11 taken out from the solution adsorbs enough acidic potassium chloride galvanizing solution. After the polyester fiber cotton 11 adsorbed with the galvanizing solution is wrapped around the galvanized layer to be repaired, zinc ions can be provided by the acidic potassium chloride galvanizing solution inside the polyester fiber cotton 11. The place where the galvanized layer to be repaired serves as the cathode, and the zinc mesh 3 serves as the anode.
[0035] Refer to Figure 2 , the thickness of the upper surface of the zinc mesh 3 from the upper surface of the polyester fiber cotton 11 is less than the thickness of the lower surface of the zinc mesh 3 from the lower surface of the polyester fiber cotton 11. In this embodiment, the zinc mesh 3 is preferably arranged at 1 / 3 of the thickness of the polyester fiber cotton 11. When the thin side of the polyester fiber cotton 11 is closely attached to the place where the galvanized layer to be repaired, the electroplating solution provided by the polyester fiber cotton 11 is less. At the same time, since the distance between the anode and the cathode is shorter, the current passing through during electroplating is smaller and the electroplating time is shorter; when the thick side of the polyester fiber cotton 11 is closely attached to the place where the galvanized layer to be repaired, the electroplating solution provided by the polyester fiber cotton 11 is more. At the same time, since the distance between the anode and the cathode is longer, the current passing through during electroplating is larger and the electroplating time is longer. When in use, the staff can select the upper and lower surfaces of the polyester fiber cotton 11 according to the needs of the repair area of the galvanized pipeline on site, so as to control the current passing through the zinc mesh 3 to optimize the electroplating effect.
[0036] Refer to Figure 1 and Figure 2 , when in use, since both ends of the polyester fiber cotton 11 are bent to form a repair sleeve for wrapping on the galvanized pipeline, and the repair sleeve can be bent along its own length direction, the polyester fiber cotton 11 can be fitted and wrapped on galvanized pipelines of various shapes, such as: at elbows, reducers, etc., so as to effectively electroplate and repair galvanized pipelines of different shapes, thereby improving the practicability of the overall device.
[0037] Refer to Figure 1 and Figure 2 , a bundling member 12 is wound around the polyester fiber cotton 11. The bundling member 12 can be set as an insulating tie strap, bundling rope or binding band. In this embodiment, the bundling member 12 is preferably set as a tie strap. In order to prevent the polyester fiber cotton 11 from loosening or falling off during electroplating, multiple tie straps can be set according to the use needs, and the multiple tie straps are arranged at intervals along the length direction of the repair sleeve. In this embodiment, the tie straps are preferably set as two, and the two tie straps are respectively bundled at both ends along the length direction of the repair sleeve, thereby improving the stability of the polyester fiber cotton 11 wrapped around the galvanized layer to be repaired.
[0038] Refer to Figure 1 and Figure 3, the rectifying mechanism 2 includes a rectifier 21, a strong magnetic grounding device 22 and a second wire 23. The rectifier 21 is provided with a positive electrode and a negative electrode. One side of the zinc mesh 3 is electrically connected to a first wire 31, and the other end of the first wire 31 is electrically connected to the positive electrode of the rectifier 21. An insulating layer 32 is provided at the connection between the first wire 31 and the zinc mesh 3. In this embodiment, the insulating layer 32 is preferably made of nylon material. The insulating layer 32 is used to prevent current leakage at the connection between the zinc mesh 3 and the first wire 31 during electroplating, thereby protecting the safety of the operator and the device, and at the same time preventing the zinc mesh 3 from being consumed too quickly as an anode.
[0039] Refer to Figure 1 and Figure 3 , the strong magnetic grounding device 22 includes a conductive rod 221 and a fixing frame 222. A strong magnet 223 is provided on the fixing frame 222. The strong magnetic grounding device 22 stably adsorbs on the galvanized pipe by the strong magnetism of the strong magnet 223. One end of the conductive rod 221 passes through the fixing frame 222 and then overlaps on the outer wall of the galvanized pipe. The conductive rod 221 is threadedly connected to the fixing frame 222. The end of the conductive rod 221 away from the galvanized pipe is electrically connected to one end of the second wire 23, and the other end of the second wire 23 is electrically connected to the negative electrode of the rectifier 21.
[0040] Refer to Figure 1 and Figure 3 , the rectifier 21 is electrically connected to an external circuit. When the rectifier 21 is powered on, the alternating current of the external circuit is converted into direct current by the rectifier 21, and the magnitude of the direct current is adjusted. Then the current starts from the positive electrode of the rectifier 21, reaches the zinc mesh 3 through the first wire 31, and then forms an electrolyte environment with the polyester fiber cotton 11 at the galvanized layer to be repaired for electroplating. The current returns to the strong magnetic grounding device 22 through the galvanized pipe, and then flows back to the negative electrode of the rectifier 21 through the second wire 23, forming a complete current closed loop.
[0041] The implementation principle of the embodiment of this application is as follows: During actual operation, the staff first grinds and polishes the galvanized layer to be repaired to remove the welding slag, oil stain, oxide layer, etc. on its surface, then immerses the polyester fiber cotton 11 in the prepared electroplating solution, takes it out after the polyester fiber cotton 11 is completely soaked, then wraps the polyester fiber cotton 11 around the galvanized layer to be repaired, and fixes the polyester fiber cotton 11 on the galvanized pipe through a tie strap. Then, the other end of the first wire 31 electrically connected to the zinc mesh 3 is electrically connected to the positive electrode of the rectifier 21. Finally, the strong magnetic grounding device 22 is attached to the galvanized pipe, and the conductive rod 221 of the strong magnetic grounding device 22 is electrically connected to the negative electrode of the rectifier 21 through the second wire 23. Then, the galvanized pipe can be electroplated through the cooperation of the rectifier 21, the first wire 31, the second wire 23, the strong magnetic grounding device 22 and the adsorption cotton 1 with the zinc mesh 3.
[0042] During the electroplating process, the zinc mesh 3 serves as the anode, the galvanized pipe serves as the cathode, and the galvanized solution adsorbed by the polyester fiber cotton 11 serves as the electroplating solution. The rectifier 21 is powered on and adjusted to an appropriate current magnitude, thereby realizing galvanizing at the location of the galvanized layer to be repaired. After electroplating for 5 minutes, the polyester fiber cotton 11 is immersed back into the electrogalvanizing solution and the above electroplating steps are repeated. The electroplating time is controlled within 15 - 25 minutes according to the thickness of the required galvanized layer. And when the zinc mesh 3 serving as the anode is consumed to a certain extent, this device needs to be replaced.
[0043] In order to achieve good electroplating effects, electroplating additives need to be added to the electrogalvanizing solution, and the temperature of the electrogalvanizing solution is controlled at 25 - 30 degrees Celsius. If the ambient temperature is too low, the electrogalvanizing solution needs to be heated before use; after electroplating is completed, an anti-rust paint is applied onto the galvanized pipe that has been galvanized, further improving the anti-corrosion performance of the galvanized pipe.
[0044] The above are all the preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
