Description

Technical Field

[0001] The utility model relates to the technical field of cathodic protection system testing devices, in particular to a cathodic protection test pile. Background Technique

[0002] To reduce the influence of external corrosion on long-distance oil and gas pipelines and ensure the safe and reliable operation of pipelines, relevant domestic and foreign standards have made mandatory requirements: pipelines put into production must be equipped with corresponding cathodic protection systems. Even during the construction stage or after completion but before commissioning, temporary cathodic protection measures need to be considered. After the pipeline is put into operation, it is also necessary to regularly monitor the operation status of the cathodic protection system to ensure its normal operation. At the same time, in order to improve the accuracy and timeliness of monitoring data and reduce the manual monitoring cost, intelligent cathodic protection test piles are usually set along the pipeline at present to collect cathodic protection data regularly and upload it to the server.

[0003] For the convenience of production and transportation, the pile body and the antenna of the existing cathodic protection test pile are usually produced separately, and the antenna is assembled on the side wall of the pile body during installation. However, this will cause one side of the antenna to be blocked by the pile body, affecting signal transmission. Especially for intelligent cathodic protection test piles, they are usually in the wild environment where the signal is relatively poor, and the signal transmission is greatly affected by obstacles. The blockage of the pile body will result in poor signal quality and affect the reliability of data transmission. Content of the Utility Model

[0025] Embodiment 1

[0026] Please refer to Figure 1 As shown, this embodiment provides a cathodic protection test pile, which includes: a pile body 100, an antenna 200, and a test circuit 300. The test circuit 300 is arranged inside the pile body 100. An installation part 400 for installing the antenna 200 is arranged at the top of the pile body 100. An installation through hole 401 is formed in the side wall of the installation part 400. The antenna 200 is arranged in the installation part 400, and the transceiver end of the antenna 200 is exposed out of the installation through hole 401.

[0027] Please refer to Figure 1 and Figure 2As shown in the figure, the pile body 100 is a hollow columnar structure, which is vertically installed at the position to be tested. The interior of the pile body 100 is used to place the test circuit 300. The pile body 100 plays a protective role to prevent the internal electronic components from being damaged by external impacts or the circuit from being damaged by contacting liquids. An installation part 400 is provided at the top of the pile body 100. The installation part 400 is used to fix the communication antenna 200, so that the antenna 200 is located at the top of the pile body 100 to ensure the signal transmission quality. Specifically, an installation through-hole 401 is provided in the installation part 400. One end of the antenna 200 is connected to the installation part 400 and is electrically connected to the test circuit 300 inside the pile body 100 through an electric wire. The other end of the antenna 200 is the signal transceiver end, and the transceiver end of the antenna 200 is exposed out of the installation through-hole 401. The installation through-hole 401 penetrates through the installation part 400. When the antenna 200 is fixed in the installation through-hole 401, the transceiver end of the antenna 200 is completely exposed to the outside through the installation through-hole 401, avoiding the installation part 400 from blocking the antenna 200 and affecting the signal transmission. At the same time, the installation part 400 can also provide a certain protection for the antenna 200. Since the antenna 200 is arranged in the installation through-hole 401, the installation part 400 will receive external impacts first, preventing the fragile antenna 200 from being broken and damaged, and improving the safety during transportation and use. The antenna 200 is arranged in the installation through-hole 401 of the installation part 400, forming an integral body with the installation part 400, which can ensure the stability of the antenna 200 to a certain extent and prevent the antenna 200 from shaking greatly when being blown by wind or rained on, affecting the signal transmission. It can be understood that the intelligent cathodic protection test pile is usually in the field environment where the signal is relatively poor. Whether the antenna 200 is blocked and whether the antenna 200 is stable have a relatively obvious impact on the signal transmission. The cathodic protection test pile provided in this embodiment improves the stability of signal transmission and the signal transmission quality by providing a through installation through-hole 401 in the installation part 400 and fixing the antenna 200 in the installation through-hole 401 to ensure the stability of the antenna 200 and avoiding the installation part 400 from blocking the antenna 200 through the installation through-hole 401.

[0028] Optionally, in some embodiments of this embodiment, a seal is provided at the connection between the antenna 200 and the installation part 400.

[0029] In this embodiment, the antenna 200 is detachably connected to the mounting part 400. Optionally, the mounting part 400 is provided with a mounting hole, and the antenna 200 is inserted into the mounting hole. The mounting hole communicates with the interior of the pile body 100, facilitating the threading of the wire for connecting the antenna 200 and the test circuit 300. A ring-shaped seal is provided in the mounting hole, and the seal can be made of elastic rubber or silica gel. After the antenna 200 is installed, the seal forms an interference fit with the antenna 200 and the mounting part 400, ensuring the sealing performance at the connection between the antenna 200 and the mounting part 400, preventing liquid from entering the interior of the pile body 100 through the gap between the antenna 200 and the mounting part 400 and damaging the circuit, and ensuring the service life of the device.

[0030] Optionally, in some embodiments of this embodiment, the mounting part 400 is arranged in a flat structure.

[0031] Please refer to Figure 1 and Figure 2 As shown, in this embodiment, the mounting part 400 is arranged in a flat square structure, facilitating the machining of the mounting through-hole 401 on the mounting part 400. At the same time, the flat-mounted mounting part 400 and the mounting through-hole 401 can avoid the antenna 200 to the greatest extent, reduce the shielding of the antenna 200, and thus improve the signal transmission effect of the antenna 200.

[0032] Optionally, in some embodiments of this embodiment, the test circuit 300 includes a data acquisition device 302 and a central control device 301. Both the data acquisition device 302 and the antenna 200 are electrically connected to the central control device 301.

[0033] Please refer to Figure 1 and Figure 2 As shown, in some embodiments of this embodiment, the central control device 301 is an integrated programmable logic controller of any existing model, which can achieve data detection control and upload effect. The specific circuit design is not limited in this embodiment. The data acquisition device 302 transmits the collected data to the central control device 301. After being processed by the central control device 301, the signal is transmitted through the antenna 200, and the collected data is remotely transmitted to an external monitoring device, facilitating the staff to remotely monitor the operation status of the cathodic protection system.

[0034] Optionally, in some embodiments of this embodiment, the test circuit 300 further includes a battery 303, and the battery 303 is electrically connected to the central control device 301.

[0035] Please refer to Figure 1 and Figure 2As shown, in this embodiment, the battery 303 is disposed inside the pile body 100 and is used to store electrical energy to supply power to the test circuit 300, ensuring the normal operation of the test circuit 300. At the same time, the electrical connection between the battery 303 and the central control device adopts a quick-disassembly design, facilitating subsequent battery replacement and maintenance.

[0036] Optionally, in some embodiments of this embodiment, a guiding inclined surface 500 is provided at the connection between the pile body 100 and the installation part 400, and the guiding inclined surface 500 is used to guide rainwater to slide off.

[0037] Please refer to Figure 2 As shown, in this embodiment, a frustum-shaped connecting part is provided at the connection between the pile body 100 and the installation part 400, and the outer sidewall of the connecting part forms an inclined guiding inclined surface 500. The guiding inclined surface 500 is used to guide rainwater or dew to slide off quickly along the pile body 100, preventing liquid from accumulating at the top of the pile body 100.

[0038] Optionally, in some embodiments of this embodiment, a hydrophobic coating is provided on the outer sidewall of the pile body 100, and the hydrophobic coating is used to reduce the roughness of the outer sidewall of the pile body 100, enabling the external part of the pile body 100 to drain water quickly and preventing liquid from adhering to the sidewall of the pile body 100 and causing rust.

[0039] Optionally, in some embodiments of this embodiment, the installation through-hole 401 is set as an oval structure.

[0040] Please refer to Figure 1 and Figure 2 As shown, in this embodiment, the installation through-hole 401 is formed as an oval structure, and the two foci of the installation through-hole 401 are distributed along the vertical direction, forming a relatively large installation space in the vertical direction for facilitating the installation of the vertical antenna 200, enabling a longer part of the antenna 200 to be exposed outside the installation through-hole 401, ensuring the length of the signal transceiver end of the antenna 200, and improving the quality of signal transmission. The oval installation through-hole 401 is also convenient for processing.

[0041] Optionally, in some other embodiments, the installation through-hole 401 can also be formed in a circular or polygonal structure.

[0042] Optionally, in some embodiments of this embodiment, a maintenance opening 101 is provided on the pile body 100.

[0043] Please refer to Figure 1As shown, in this embodiment, the pile body 100 is a hollow shell structure, and the inside is used to install and fix the test circuit 300. An inspection opening 101 is provided on the side wall of the pile body, and the position of the inspection opening 101 corresponds to that of the test circuit 300, which is convenient for staff to install electronic components inside the pile body 100 and for maintaining the cathode test circuit 300. In this embodiment, the data acquisition device 302 of the test circuit 300 includes multiple acquisition channels, which are respectively used to detect multiple data (such as voltage, current, etc.) of the cathodic protection system. The central control device 301 is connected to the terminal block and is connected to the pipeline under cathodic protection and related sampling specimens through the terminal block. The operator can connect the wires of the data acquisition device 302 to the terminal block through the inspection opening 101, which is convenient for replacing the damaged data acquisition device 302.

[0044] Optionally, in some embodiments of this embodiment, a protection door is covered at the inspection opening 101, and the protection door is detachably connected to the pile body 100.

[0045] In this embodiment, a protection door is covered at the inspection opening 101. This makes the inside of the pile body 100 form a relatively enclosed space, reduces the risk of the test circuit being damaged by humans and bad weather when exposed, and improves the service life and safety of the entire cathodic protection test pile. The protection door is detachably connected to the pile body 100, which is convenient for staff to remove the protection door for maintenance during maintenance.

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

[0047] Optionally, in some embodiments 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 pile body 100.

[0048] In this embodiment, the sealing ring can be made of soft materials such as rubber or silica gel. The sealing ring is provided at the edge of the protection door. When the protection door is closed, the sealing ring abuts against the periphery of the inspection opening 101 of the pile body 100 to form an interference fit, ensuring the sealing performance between the protection door and the pile body 100, making the inside of the pile body 100 form a sealed space, and further preventing external liquid from entering the inside of the pile body 100 to corrode electronic components and cause circuit damage.

[0049] Optionally, in some embodiments of this embodiment, the sealing ring is detachably connected to the protection door. The sealing ring is made of soft rubber or silica gel material, so as to improve the sealing effect. However, rubber or silica gel will oxidize after long-term use, resulting in the loss of the sealing function. At this time, the staff can detach and replace the sealing ring to ensure the use effect of the sealing ring.

[0050] In summary, the present utility model provides a cathodic protection test pile, which comprises: a pile body 100, an antenna 200, and a test circuit 300. The test circuit 300 is disposed inside the pile body 100. An installation part 400 for installing the antenna 200 is provided at the top of the pile body 100.
