Description

Technical Field

[0001] This utility model relates to the field of pipeline cathodic protection technology, and in particular to a pipeline cathodic protection experimental device. Background Technology

[0002] Cathodic protection of oil pipelines is a technical measure to prevent electrochemical corrosion of oil pipelines.

[0003] The cathodic protection testing device for oil pipelines is a specialized piece of equipment used to study and test the effectiveness of cathodic protection for oil pipelines. It provides an important means for researching and optimizing cathodic protection systems for oil pipelines. Through scientific testing and analysis, the performance and reliability of the cathodic protection system can be improved, ensuring the safe operation of oil pipelines.

[0004] In existing technologies, the principle of pipeline cathodic protection is to provide electrons to the pipeline, making it a cathode, thereby inhibiting the corrosion of the pipeline metal. Experimental devices observe the potential changes of the pipeline under different cathodic protection methods to understand the working principle of cathodic protection, simulate the cathodic protection effect of pipelines under different environmental conditions and with different sizes and materials, and provide a reference for environmental adaptability assessment of actual engineering projects. However, there are shortcomings. The structure of the pipeline cathodic protection experimental device is relatively simple, and it is inconvenient to store, fix and operate. When simulating the cathodic protection effect of pipelines of different sizes, operators need to fix and test each one one by one. After testing one, the simulated pipeline is removed and then different sizes of simulated pipelines are installed. Finally, the experimental data is compared. The overall operation is relatively complicated, the experimental cycle is long, and the experimental efficiency is greatly reduced. Therefore, a pipeline cathodic protection experimental device is proposed to solve the above problems. Utility Model Content

Each pair of guide strips is slidably connected to a shelf, and each shelf is symmetrically provided with clamping components on the upper side.

A potential tester 18 and a current tester 19 are fixedly connected to the outer side of the cabinet door 2, which are used to measure the potential and current values ​​in the experiment, thereby judging the actual effect of cathodic protection. Multiple pairs of guide bars 3 are evenly fixedly connected from top to bottom on the inner side of the cabinet 1. The guide bars 3 are used to provide moving support for the shelves 4, which facilitates the picking and putting of the shelves 4. A shelf 4 is slidably connected between each pair of guide bars 3. Clamping parts are symmetrically arranged on the upper side of each shelf 4.

[0032] Each clamping component includes two sliders 5 symmetrically arranged front and back and two support blocks 10 symmetrically arranged front and back. The support blocks 10 are fixedly assembled with the shelf 4. The top of the shelf 4 is provided with a sliding groove 6, which limits the movement trajectory of the sliders 5 and improves the operational stability. The sliding groove 6 is slidably assembled with the sliders 5. The upper end of the sliders 5 is fixedly connected with a connecting block 7. A clamping plate 9 is fixedly installed at the end of each pair of connecting blocks 7 that is close to each other. The middle of the support block 10 is provided with a through groove along the longitudinal direction. The side of each pair of connecting blocks 7 that is far from each other is slidably assembled with the through groove. A positioning component is provided between the support block 10 and the connecting block 7 for quick positioning of the clamping plate 9, making the adjustment of the clamping plate 9 more stable.

[0033] The top of the cabinet 1 is equipped with a simulated power supply 15 to provide current and simulate experimental electronics. The output end of the simulated power supply 15 is fixedly connected to a power transmission line 16 for stable transmission of electrons. The bottom of the shelf 4 is equipped with a fixing component.

[0034] Reference Figure 5The positioning assembly includes a movable rod 11 and a hole 8. The hole 8 is used to limit and protect the movable rod 11. The movable rod 11 is slidably connected to the middle of the support block 10 along the lateral direction. A limiting piece 13 is fixedly connected to the outside of the movable rod 11. A spring 12 is sleeved on the outside of the movable rod 11, and the spring 12 abuts against the movable rod 11 and the limiting piece 13. Multiple holes 8 are evenly opened longitudinally at the end of the connecting block 7 away from the clamping plate 9. The movable rod 11 is slidably connected inside one of the holes 8. The movable rod 11 is used to drive the limiting piece 13 to move and squeeze the spring 12, so that the movable rod 11 is disengaged from the hole 8, and the slider 5 can move freely. The slider 5 drives the clamping plate 9 to move. The multiple clamping plates 9 complete the clamping of the simulated pipe 14. When the movable rod 11 is released, the spring 12 drives the limiting piece 13 to move under the reaction force. The limiting piece 13 drives the movable rod 11 to move and close to the hole 8. The components are snapped together to quickly fix simulated pipes 14 of different sizes. The operation is convenient and easy to learn. The fixing components include a connecting block 21, which is fixedly connected to the bottom of the shelf 4. A pressure block 22 is rotatably connected to the bottom of the connecting block 21. A spring piece 23 is fixedly connected between the shelf 4 and one end of the pressure block 22. An insert block 24 is fixedly connected to the top of the other end of the pressure block 22. The pressure block 22 is used to squeeze the spring piece 23, so that the pressure block 22 drives the insert block 24 to move downward and disengage from the slot 25, allowing the shelf 4 to move freely. Then, the shelf 4 is pulled outward. After the simulated pipes 14 are disassembled, installed and repaired in the shelf 4, the shelf 4 is inserted and the pressure block 22 is released. The reaction force of the spring piece 23 drives the pressure block 22 to move downward. The pressure block 22 drives the insert block 24 to move upward and snap together with the slot 25, thus quickly and conveniently completing the layered storage of the shelf 4.

[0035] Reference Figures 1-5 The bottom of the guide bar 3 is provided with a slot 25, and the plug 24 is slidably connected to the middle of the slot 25.

An anode block 17 is provided on the top of the simulated pipe 14 to provide electrical protection for the simulated pipe 14. A temperature and humidity controller 20 is fixedly connected to the outside of the cabinet 1 to control the temperature and humidity and ensure the working environment.

[0036] Working principle: First, open cabinet door 2, press down block 22, block 22 squeezes spring 23, block 22 drives insert block 24 to move downward and disengage from slot 25, so that shelf 4 can move freely. Then, pull shelf 4 outward, and after completing the disassembly, installation and maintenance of simulated pipe 14 in shelf 4, insert shelf 4, release block 22, spring 23 reaction force drives block 22 to move downward, block 22 drives insert block 24 to move upward and engage with slot 25, quickly and conveniently complete the layered storage of shelf 4.

[0037] Secondly, when installing simulated pipes 14 of different sizes, the simulated pipes 14 are placed between clamping plates 9. Pulling the moving rod 11 outward causes the moving rod 11 to move the limiting plate 13 and squeeze the spring 12, so that the moving rod 11 is disengaged from the hole 8, allowing the slider 5 to move freely. The slider 5 moves the clamping plates 9, and multiple clamping plates 9 clamp the simulated pipes 14. Then, the moving rod 11 is released, and the spring 12 moves the limiting plate 13 under the reaction force. The limiting plate 13 moves the moving rod 11 and engages with the hole 8, quickly completing the fixation of simulated pipes 14 of different sizes. The simulated power supply 15 is turned on, and the current from the simulated power supply 15 is sent to the top of the simulated pipes 14 through the transmission line 16. The potential tester 18 and the current tester 19 are used to observe and record the changes. The temperature and humidity controller 20 is turned on to simulate different temperature and humidity scenarios, and the potential and current changes of the simulated pipes 14 at different temperatures and humidity are observed.
