Description

Technical Field

[0001] The invention relates to the technical field of corrosion testing, in particular to a reinforced concrete rapid corrosion testing device. Background Art

[0002] At present, the main factor inducing the deterioration of the durability of reinforced concrete structures is steel corrosion, which is caused by a variety of factors, such as Cl- corrosion, CO2, O2 and temperature. Among them, Cl- corrosion is the main factor, and the effects of carbonization, oxidation and temperature on steel corrosion are generally small. However, in order to better study the corrosion process of steel bars, it is also necessary to comprehensively consider factors such as carbonization, oxidation and temperature.

[0003] In the prior art, in order to better simulate the influence of complex environment on steel corrosion, the corrosion test device is often able to simulate multiple environmental factors simultaneously, so as to test the influence of multi-factor coupled environment on steel corrosion.

Existing corrosion test devices can only simulate and couple multiple factors at the same time, but cannot test the influence of a single factor on steel bar corrosion. The staff cannot explore the influence of a certain factor on steel bar corrosion, and the test results are not comprehensive enough.

At the same time, the test personnel can also selectively connect the sub-test chambers according to actual needs to form multiple preparatory test chambers (such as when not connected, one sub-test chamber can form a preparatory test chamber), and by placing the corrosion test assembly in the multiple preparatory test chambers, the synchronous corrosion test of multiple test pieces 22 can be realized, which greatly improves the test efficiency of the test personnel, thereby solving the problem that the test results of the steel corrosion test device in the prior art are not comprehensive and the test efficiency is low.

[0057] In this embodiment, the plate-shaped rotating end 16 is a fan-shaped structure to avoid interference with the inner wall of the test chamber during rotation, thereby improving the rotation reliability of the plate-shaped rotating end 16 .

[0058] like Figure 5As shown, the plate-like rotating end 16 also has a third plug-in portion 162, and the box body 1 also has an installation cavity 49 located below the test cavity. The rotating assembly also includes: a third driving device 14, which is arranged in the installation cavity 49, and the driving end of the third driving device 14 extends into the test cavity; a connecting member 13, which is arranged on the driving end of the third driving device 14, and the connecting member 13 has a fourth plug-in portion 15, one of the third plug-in portion 162 and the fourth plug-in portion 15 is a plug-in protrusion, and the other of the third plug-in portion 162 and the fourth plug-in portion 15 is a plug-in recess, the plug-in protrusion extends into the plug-in recess and is plug-matched with the plug-in recess, and the third driving device 14 is used to drive the connecting member 13 to drive the plate-like rotating end 16 to rotate; wherein, there are multiple fourth plug-in portions 15, there are multiple plate-like rotating ends 16, and multiple fourth plug-in portions 15 are arranged at intervals around the rotation axis of the connecting member 13, and multiple fourth plug-in portions 15 are arranged one-to-one with multiple third plug-in portions 162 of the plate-like rotating ends 16. In this way, the third driving device 14 realizes the automatic rotation of the plate-shaped rotating end 16, and the third driving device 14 is arranged in the installation cavity, so that the third driving device 14 can be separated from the test cavity to prevent its corrosion, thereby extending the service life of the third driving device 14. At the same time, the above-mentioned arrangement of the connecting member 13 ensures that the third driving device 14 can simultaneously drive multiple plate-shaped rotating ends 16 to rotate while realizing the driving connection between the third driving device 14 and the plate-shaped rotating end 16, that is, realizes the installation of multiple test pieces 22 and the corresponding corrosion test, thereby improving the test efficiency of the reinforced concrete rapid corrosion test device.

[0059] In this embodiment, there are four partition structures 5 and four sub-test chambers, and correspondingly, there are also four plate-shaped rotating ends 16.

[0060] It should be noted that the drawings only show the structure when one plate-shaped rotating end 16 is installed, and the test personnel can make corresponding adjustments.

[0061] Specifically, since the opening size of the box door 23 is limited after it is opened, in fact, the setting of the plate-like rotating end 16 can also facilitate the test personnel to install the support and the test piece 22. That is, after the test personnel have plugged in a support and installed a test piece 22, they can operate the third driving device 14 to drive the plate-like rotating end 16 to rotate, so as to rotate the plate-like rotating end 16 without the support installed to correspond to the box door 23, thereby facilitating the test personnel to install it.

[0062] Specifically, the number of electrolytic cells 25 can also be increased according to actual needs.

[0063] Specifically, the third plug-in portion 162 is a through hole, the fourth plug-in portion 15 is an L-shaped plate, the connector 13 is disc-shaped as a whole, one plate segment of the fourth plug-in portion 15 is connected to the outer peripheral surface of the connector 13 , and the other plate segment is inserted into the third plug-in portion 162 .

In this way, the above-mentioned configuration enables the reinforced concrete rapid corrosion test device in this embodiment to simulate and couple humidity, carbon dioxide gas concentration, and oxygen concentration, so as to meet the influencing factors of the steel corrosion test to the greatest extent and ensure that the test structure is sufficiently comprehensive.

[0065] Specifically, the reinforced concrete rapid corrosion test device in this embodiment can simulate humidity, carbon dioxide gas concentration and oxygen concentration individually, or simulate any two of the three at the same time, or simulate all three at the same time, so as to meet the requirements of influencing factors of corrosion test to the greatest extent.

At the same time, by further separating the refrigeration chamber 50 through the partition 12, the refrigeration end 9 can be separated and protected to prevent the gas or liquid in the sub-test chamber from affecting the service life of the refrigeration device. At the same time, the setting of the refrigeration device and the heating device 8 can further adjust the temperature in the corrosion chamber 45 to further increase the environmental conditions that can be simulated by the reinforced concrete rapid corrosion test device, ensuring that the test structure is more comprehensive and accurate.
