Description

Technical Field

[0001] The utility model relates to the technical field of cathode protection devices, in particular to a cathode protection testing device. Background Art

[0002] As the main component of the intelligent cathodic protection test device, the pile body of the intelligent cathodic protection test pile can serve as a structural part of the equipment, supporting and protecting the built-in intelligent potential collector; on the other hand, it can also serve as a line channel connecting the collector and the reference electrode, guiding and protecting the connecting line between the collector and the reference electrode.

[0003] During the typical installation of an intelligent cathodic protection test device, the reference electrode and corresponding test specimen connection wires pass through the opening in the middle of the reference tube and the opening on the side of the bottom of the test pile, then upward to connect to the corresponding input terminal of the intelligent potential collector. This ultimately enables the collection and upload of pipeline cathodic protection data. The existing design and installation method of the intelligent cathodic protection test device can achieve data collection from each collection channel. However, the following technical issues exist:

[0004] 1. The connecting wires between the reference electrode, test strip, and collector are all intact and buried in the soil during installation. If the reference electrode or test strip fails and needs to be replaced later, the entire test pile must be excavated and rewired from the wiring terminals inside the test pile. This operation is labor-intensive, cumbersome, and costly.

[0005] 2. There is a certain distance between the reference tube and the pile body, and the connecting wire is exposed in the soil, which is easily damaged by external operations, resulting in abnormal data collection.

[0006] 3. There are usually about 5 to 6 collection lines connected from the bottom to the top of the pile body. The collection lines are of different lengths, bent inside the pile and arranged in a disorderly manner, which will interfere with the installation and maintenance operations of the equipment to a certain extent, making the operation not very convenient and the inspection and maintenance difficult.

[0027] Example 1

[0028] Please refer to Figure 1As shown, this embodiment provides a cathodic protection test device, which includes: a test pile body 100, a cathodic protection data acquisition module 200, a reference tube 300, a wire connector 400, and a sensor 500. The cathodic protection data acquisition module 200 is disposed inside the test pile body 100, the wire connector 400 is disposed on the reference tube 300, and the wire connector 400 is connected to the cathodic protection data acquisition module 200 via a first wire 600. The sensor 500 is disposed in the reference tube 300, and the sensor 500 is connected to the wire connector 400 via a second wire 700, so that the sensor 500 is electrically connected to the cathodic protection data acquisition module 200.

[0029] In this embodiment, the test pile body 100 is a hollow columnar structure, and the interior is used to install and fix the cathodic protection data acquisition module 200. The cathodic protection data acquisition module 200 is connected to the wire connector 400 on the reference tube 300 through the first wire 600. At the same time, a plurality of sensors 500 are arranged in the reference tube 300, and the sensor 500 is connected to the wire connector 400 on the reference tube 300 through the second wire 700, thereby electrically connecting the cathodic protection data acquisition module 200 and the sensor 500. The cathodic protection data acquisition module 200 collects various operating data of the cathodic protection system through the first wire 600, the wire connector 400 and the second wire 700 through the sensor 500, and sends it to the corresponding monitoring platform, so that the staff can observe whether the cathodic protection system is working normally. Please refer to Figure 1 As shown, one end of the first wire 600 is arranged inside the test pile body 100 and is electrically connected to the cathodic protection data acquisition module 200. The other end of the first wire 600 extends to the outside of the test pile body 100 and is connected to the wire connector 400 on the reference tube 300. During installation, the first wire 600 can be buried underground, thereby protecting the first wire 600. The sensor 500 in the reference tube 300 is connected to the wire connector 400 on the reference tube 300 via the second wire 700. When the sensor 500 is damaged, the corresponding sensor 500 and the second wire 700 can be directly replaced in the reference tube 300 without having to dig up the first wire 600 buried underground. The operation of installation and subsequent maintenance is relatively convenient.

[0030] Optionally, in some implementations of this embodiment, the sensor 500 includes a reference electrode 501, a current test strip 502, and a potential test strip 503. The reference electrode 501, the current test strip 502, and the potential test strip 503 are all disposed inside the reference tube 300, and the reference electrode 501, the current test strip 502, and the potential test strip 503 are detachably connected to the wire connector 400 via the second wire 700.

[0031] Please refer to Figure 1As shown, in this embodiment, the sensor 500 includes a reference electrode 501, a current test strip 502 and a potential test strip 503. The potential test strip 503 includes a power-off potential test strip 503 and a natural potential test strip 503. The reference electrode 501 serves as a reference comparison electrode, and cooperates with the current test strip 502, the power-off potential test strip 503 and the natural potential test strip 503 to detect the circuit working condition of the cathodic protection system.

[0032] Optionally, in some implementations of this embodiment, a protective wire tube 800 is provided on the outside of the first wire 600 , one end of the protective wire tube 800 is disposed inside the test pile 100 , and the other end of the protective wire tube 800 is detachably connected to the wire connector 400 .

[0033] Please refer to Figure 1 and Figure 2 As shown, in the present embodiment, the inside of test pile body 100 is provided with protection wire pipe 800, one end of protection wire pipe 800 extends to the outside of test pile body 100 and is connected with the wire connector 400 on the reference tube 300, and the first electric wire 600 is arranged in the protection wire pipe 800.It is understandable that when actual negative protection test device is installed, because reference tube 300 and test pile body 100 have certain interval, it is necessary to connect the sensor 500 in the reference tube 300 to the negative protection data acquisition module 200 inside test pile body 100 by electric wire.The electric wire connected needs to pass the side wall of test pile body 100 and be exposed in the air, easily age or be damaged.Existing protection means normally directly buries exposed electric wire underground, but because test pile is usually arranged on the place where environment is poor, buried electric wire still exists and is corroded or by the risk of artificial construction or wild animal destruction. Furthermore, buried wires are very troublesome to inspect and replace, especially when multiple sensors 500 are installed in the reference tube 300, which requires connecting multiple wires, making inspection and maintenance even more difficult. In this embodiment, a protective wire tube 800 is provided, buried underground, and then the first wire 600 is passed through the protective wire tube 800. On the one hand, the protective wire tube 800 can protect the first wire 600 inside and prevent the first wire 600 from being corroded or damaged by external liquids. On the other hand, a cavity is formed in the protective wire tube 800 to facilitate the removal of the first wire 600 from the protective wire tube 800 at a later time. When replacing the first wire 600, there is no need to dig out the protective wire tube 800. Instead, the first wire 600 only needs to be pulled out of the protective wire tube 800 and the new first wire 600 can be passed through the protective wire tube 800. The operation is convenient and quick.

[0034] Optionally, in some implementations of this embodiment, the protective wire tube 800 is configured as a U-shaped structure.

[0035] Please refer to Figure 1 and Figure 2As shown, in this embodiment, one end of the protective conduit 800 is disposed inside the test pile body 100, and the other end of the protective conduit 800 is connected to the wire connector 400. The protective conduit 800 is configured as a U-shaped structure. The portion of the protective conduit 800 exposed from the test pile body 100 can be pre-buried underground. Both ends of the protective conduit 800 are above the ground. On the one hand, the two ends of the protective conduit 800 exposed from the ground facilitate connection to the wire connector 400 on the reference tube 300. On the other hand, the middle section of the protective conduit 800 is buried underground to prevent the first wire 600 from being corroded or damaged, thereby improving the stability of data acquisition.

[0036] Optionally, in some implementations of this embodiment, a chamfered structure is provided at the bend of the protective wire tube 800 .

[0037] Please refer to Figure 2 As shown, in this embodiment, the protective conduit 800 is configured as a U-shaped structure, and the bend of the protective conduit 800 is provided with a right-angled or arc-shaped chamfered structure, forming a smooth corner, which facilitates the insertion of the first wire 600. It can be understood that when installing the wires, the first wire 600 needs to be inserted from one end of the protective conduit 800 and passed out from the other end of the protective conduit 800. When inserting the first wire 600, the chamfered structure can serve as a guide, ensuring that the first wire 600 smoothly passes through the protective conduit 800 and prevents the first wire 600 from getting stuck in the protective conduit 800.

[0038] Optionally, in some implementations of this embodiment, the cathodic protection data acquisition module 200 includes a control device 201 and a transmission antenna 202 , and the first wire 600 and the transmission antenna 202 are both electrically connected to the control device 201 .

[0039] Please refer to Figure 1 As shown, in some implementations of this embodiment, the transmission antenna 202 is disposed on the top of the test pile 100 , so as to facilitate the transmission or reception of remote signals through the transmission antenna 202 and ensure the stability of signal transmission.

[0040] Optionally, in some implementations of this embodiment, the cathodic protection data acquisition module 200 further includes a battery 203 , and the battery 203 is electrically connected to the control device 201 .

[0041] In this embodiment, the battery 203 is disposed inside the test pile 100 to store electricity and power the cathodic protection data acquisition module 200, thereby ensuring the normal operation of the cathodic protection data acquisition module 200. Furthermore, the electrical connection between the battery 203 and the control device 201 adopts a quick-disconnect design to facilitate subsequent battery replacement and maintenance.

[0042] Optionally, in some implementations of this embodiment, an inspection opening 101 is provided on the test pile 100 .

[0043] Please refer to Figure 1 As shown, in this embodiment, the test pile body 100 is a hollow shell structure, and the interior is used to install and fix the cathodic protection data acquisition module 200. The side wall of the test pile body 100 is provided with an inspection port 101, which corresponds to the installation position of the cathodic protection data acquisition module 200, facilitating the installation, operation and maintenance of the cathodic protection data acquisition module 200.

[0044] Optionally, in some implementations of this embodiment, a protective door is provided on the cover of the inspection port 101 , and the protective door is detachably connected to the test pile body 100 .

[0045] In this embodiment, a protective door is provided at the access opening 101, creating a relatively enclosed space within the test pile 100. This reduces the risk of damage to the cathodic protection data acquisition module from human intervention and inclement weather, thereby increasing the service life and safety of the entire cathodic protection test pile. The protective door is detachably connected to the test pile 100, making it easy for maintenance personnel to remove the door for inspection.

[0046] Optionally, in some other embodiments, the protection door is hinged to the test pile body 100 and can open or close the inspection opening 101 by rotating.

[0047] Optionally, in some implementations of this embodiment, a sealing ring is provided on the protection door, and the sealing ring is located at the connection between the protection door and the test pile body 100 .

[0048] In this embodiment, the sealing ring can be made of a soft material such as rubber or silicone. The sealing ring is arranged at the edge of the protective door. When the protective door is closed, the sealing ring abuts against the periphery of the inspection port 101 of the test pile body 100 to form an interference fit, thereby ensuring the sealing of the protective door and the test pile body 100, forming a sealed space inside the test pile body 100, and further preventing external liquid from entering the test pile body 100 to corrode electronic components and cause circuit damage.

[0049] Optionally, in some implementations of this embodiment, the sealing ring is detachably connected to the protective door. The sealing ring is made of soft rubber or silicone to improve sealing effectiveness. However, rubber or silicone will oxidize over time, resulting in loss of sealing effectiveness. In this case, staff can remove and replace the sealing ring to ensure its effectiveness.

[0050] In summary, the embodiment of the present invention provides a cathodic protection test device, which includes: a test pile body 100, a cathodic protection data acquisition module 200, a reference tube 300, a wire connector 400 and a sensor 500. The cathodic protection data acquisition module 200 is arranged inside the test pile body 100, the wire connector 400 is arranged on the reference tube 300, and the wire connector 400 is connected to the cathodic protection data acquisition module 200 through a first wire 600. The sensor 500 is arranged in the reference tube 300, and the sensor 500 is connected to the wire connector 400 through a second wire 700, so that the sensor 500 is electrically connected to the cathodic protection data acquisition module 200. By setting the first wire 600 and the wire connector 400, it is convenient to connect the sensor 500 through the second wire 700, which can ensure that the connecting wires in the pile body are arranged neatly and avoid interference with equipment installation and maintenance operations; at the same time, a wiring slot is provided to provide protection for the internal connecting wires, avoid damage to the connecting wires caused by external operations, and improve the safety and service life of the device.
