Description
Technical Field
[0001] This utility model belongs to the field of corrosion control and monitoring technology, and in particular relates to a pipeline cathodic protection effect detection device with remote monitoring function. Background Technology
[0002] A pipeline cathodic protection effectiveness testing device is a device used to evaluate the effectiveness of a pipeline cathodic protection system. Cathodic protection is an electrochemical protection method that prevents corrosion of metal pipelines by applying an external current or sacrificing anode materials. In the prior art, pipeline cathodic protection effectiveness testing devices also have a remote monitoring function, which enables remote real-time monitoring of the cathodic protection effect through wireless or wired communication technology.
[0003] During installation, both the reference electrode and the detection device need to be connected to the pipeline to accurately measure the cathodic protection effect, ensuring good electrical contact between the reference electrode and the pipeline surface, and a stable and reliable connection. Typically, workers weld the reference electrode and detection device to the pipeline surface. However, direct welding to the pipeline surface can damage the pipeline's anti-corrosion layer, leading to localized corrosion. Furthermore, welding creates a heat-affected zone, altering the metal structure in that area, resulting in increased local hardness, decreased toughness, and even cracks, affecting the pipeline's strength and safety. Therefore, a pipeline cathodic protection effect detection device with remote monitoring capabilities is needed to address these issues. Utility Model Content

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0024] like Figures 1 to 3 As shown, this utility model embodiment provides a pipeline cathodic protection effect testing device with remote monitoring function, including:
[0025] The main body of the equipment 1 includes a detection pile 11 and a reference electrode 12. The reference electrode 12 is electrically connected to the detection pile 11 via a cable. The detection pile 11 has a first connecting line 111, and the reference electrode 12 has a second connecting line 121.
[0026] Connection assembly 2 includes a connecting block 21 and a threaded cylinder 22. Both the connecting block 21 and the threaded cylinder 22 are provided in pairs. Each pair of connecting blocks 21 has a placement groove 211 at one opposite end for accommodating a pipe. The pair of connecting blocks 21 are detachably connected to each other at their upper and lower end faces with the placement grooves 211. Each connecting block 21 has a wire-feeding cavity 212 and a threaded cavity 213 for inserting an electrical wire. The wire-feeding cavity 212 and the threaded cavity 213 are connected. The outer wall of the threaded cylinder 22 is threaded to the inner wall of the threaded cavity 213. The threaded cylinder 22 is provided with multiple locking blocks 221 at one end away from the wire feeding cavity 212. Both the connecting block 21 and the threaded cylinder 22 are made of conductive material. The first connecting wire 111 is inserted into one of the wire feeding cavities 212, and the second connecting wire 121 is inserted into the other wire feeding cavity 212. The outer wall of the first connecting wire 111 is locked between the multiple locking blocks 221 on one of the threaded cylinders 22, and the outer wall of the second connecting wire 121 is locked between the multiple locking blocks 221 on the other threaded cylinder 22.
[0027] In this embodiment, firstly, the worker aligns the sides of a pair of connecting blocks 21 together so that the outer wall of the pipe is placed in the placement groove 211; then, the worker respectively attaches a pair of threaded cylinders 22 to the first connecting line 111 on the detection post 11 and the second connecting line 121 on the reference electrode 12; then, the first connecting line 111 and the second connecting line 121 are inserted into a pair of wire-laying cavities 212; then, the threaded cylinders 22 are rotated by the fixing post 222 so that the threaded cylinders 22 are threadedly connected to the threaded cavities 213; during the rotation of the threaded cylinders 22, the sides of multiple locking blocks 221 are aligned with each other; by setting the threaded cylinders 22, the first connecting line 111 and the second connecting line 121 are fixed to the connecting blocks 21; the electrical connection between the detection post 11 and the reference electrode 12 and the pipe can be completed without welding;
[0028] Specifically, one of the connecting blocks 21 has a limiting block 214 on the upper end of the forming placement groove 211, and the other connecting block 21 has a limiting groove 215 on the upper end of the forming placement groove 211, with the limiting block 214 engaging with the limiting groove 215.
[0029] In this embodiment, the limiting block 214 at the upper end of the placement groove 211 of one connecting block 21 is placed in the limiting groove 215 at the upper end of the placement groove 211 of the other connecting block 21; then, the worker uses welding tools to weld the gap between the limiting block 214 and the limiting groove 215, so that the pair of connecting blocks 21 are fixed to each other, avoiding direct welding to the pipe surface and damaging the anti-corrosion layer of the pipe, while preventing the generation of heat-affected zone during welding and causing cracks on the pipe surface, affecting the strength and safety of the pipe;
[0030] Specifically, the threaded cylinder 22 also includes a fixing post 222, which extends a distance outside the threaded cavity 213;
[0031] Specifically, the connecting block 21 has a plug hole 216 at the lower end of the placement groove 211. The connecting assembly 2 also includes a plug post 23 and a plug tube 24. One end of the plug post 23 has a first limiting plate 231, and one end of the plug tube 24 has a second limiting plate 241. The outer wall of the plug post 23 is threadedly connected to the inner wall of the plug tube 24. The plug tube 24 is inserted into the plug hole 216. The first limiting plate 231 is attached to the side wall of one of the connecting blocks 21, and the second limiting plate 241 is attached to the side wall of the other connecting block 21.
[0032] In this embodiment, the worker inserts the plug-in tube 24 into the plug-in hole 216, ensuring that the second limiting plate 241 at one end of the plug-in tube 24 is in contact with the side of one of the connecting blocks 21; then the plug-in post 23 is rotated so that the plug-in post 23 and the plug-in tube 24 are threadedly connected until the first limiting plate 231 at one end of the plug-in post 23 is in contact with the side of the other connecting block 21. In this way, by setting the plug-in post 23 and the plug-in tube 24, the lower end of the connecting block 21 with the placement groove 211 is fixedly connected.
[0033] Specifically, the connecting component 2 also includes a traction rope 25 and a fixing pin 26. There are two sets of traction ropes 25 and fixing pins 26. Each set of traction ropes 25 and each set of fixing pins 26 has at least one. One set of traction ropes 25 is connected at both ends to the fixing pins 26 and the first limiting plate 231, and the other set of traction ropes 25 is connected at both ends to the fixing pins 26 and the second limiting plate 241.
[0034] In this embodiment, the worker inserts the fixing nail 26 at the end of the traction rope 25 away from the first limiting plate 231 and the second limiting plate 241 into the soil. By setting the traction rope 25 and the fixing nail 26, the connecting block 21 and the pipe are firmly placed in the soil.
[0035] Specifically, the threaded cylinder 22 forms a locking protrusion 223 on the inner wall of the locking block 221. The locking protrusion 223 is set in an arc shape, and the fixing post 222 and the locking protrusion 223 are respectively placed on the adjacent end faces of the locking block 221.
[0036] In this embodiment, during the rotation of the threaded cylinder 22, the sides of the multiple engaging blocks 221 are in contact with each other; at this time, the sidewalls of the first connecting line 111 and the second connecting line 121 are both placed between the multiple engaging protrusions 223.
[0037] The working principle of this utility model is as follows:
[0038] In the initial state, the detection pile 11 and the reference electrode 12 are electrically connected by a cable. First, the worker aligns the sides of a pair of connecting blocks 21 together so that the outer wall of the pipe is placed in the placement groove 211. At this time, the limiting block 214 of one connecting block 21 at the upper end of the placement groove 211 is placed in the limiting groove 215 of the other connecting block 21 at the upper end of the placement groove 211. Then, the plug tube 24 is inserted into the plug hole 216, ensuring that the second limiting plate 241 at one end of the plug tube 24 is attached to the side of one of the connecting blocks 21.
[0039] Then, the worker rotates the plug pin 23 to make the plug pin 23 and the plug sleeve 24 threadedly connected until the first limiting plate 231 at one end of the plug pin 23 fits against the side of the other connecting block 21. In this way, by setting the plug pin 23 and the plug sleeve 24, the lower end of the connecting block 21 with the placement groove 211 is fixedly connected.
[0040] Subsequently, the workers used welding tools to weld the gap between the limiting block 214 and the limiting groove 215, so that the pair of connecting blocks 21 are fixed to each other, avoiding direct welding to the pipe surface and damaging the anti-corrosion layer of the pipe, while preventing the generation of heat-affected zone during welding and causing cracks on the pipe surface, which would affect the strength and safety of the pipe.
[0041] After the plug-in post 23 and plug-in sleeve 24 are threaded together, the worker respectively attaches a pair of threaded sleeves 22 to the first connecting line 111 on the detection post 11 and the second connecting line 121 on the reference electrode 12; then the first connecting line 111 and the second connecting line 121 are inserted into a pair of wire-laying cavities 212; then the threaded sleeve 22 is rotated by the fixing post 222 so that the threaded sleeve 22 is threadedly connected to the threaded cavity 213; during the rotation of the threaded sleeve 22, the sides of multiple locking blocks 221 are in contact with each other; at this time, the side walls of the first connecting line 111 and the second connecting line 121 are placed between multiple locking protrusions 223. In this way, by setting the threaded sleeve 22, the first connecting line 111 and the second connecting line 121 are fixed to the connecting block 21; the electrical connection between the detection post 11 and the reference electrode 12 and the pipeline can be completed without welding.
[0042] Finally, the worker inserts the fixing nail 26 at the end of the traction rope 25 away from the first limiting plate 231 and the second limiting plate 241 into the soil. By setting the traction rope 25 and the fixing nail 26, the connecting block 21 and the pipe are firmly placed in the soil.
[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
