[0002] Steel structure corrosion measurement refers to the evaluation of the steel structure's resistance to corrosion or durability by using various techniques and methods. This measurement is designed to detect whether the surface or interior of the steel structure is affected by corrosion, as well as to assess the extent and scope of corrosion. Through corrosion measurement, the health of the steel structure can be determined, and corresponding maintenance and repair plans can be formulated to extend the service life of the steel structure and ensure its safety. Commonly used corrosion measurement methods include ultrasonic testing, electrochemical corrosion monitoring, magnetic particle testing, metallographic microscope testing, etc.

[0003] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields. Before the steel structure is used, it is often necessary to sample and test it in order to test whether its corrosion resistance is qualified. At present, common detection devices on the market often require staff to manually remove corroded steel structure components, which is easy to cause harm to staff. At the same time, common detection devices take a long time to detect, cannot speed up the response time, and are inconvenient to use.

[0004] The Chinese patent with the publication number of "CN217542789U" discloses an experimental device for corrosion resistance detection of steel structures, which includes a workbench, the top four corners of the workbench are fixedly connected with connecting columns, the tops of the connecting columns are fixedly connected with a top plate, the bottom of the workbench is fixedly connected with a support box, the inner middle end of the support box is fixedly connected with a partition, the top of the workbench is fixedly connected with a detection pool, the top middle end of the workbench is provided with a limit groove, the inner part of the limit groove is clamped with a placement seat, the top of the partition is fixedly installed with an electric push rod, the output end of the electric push rod is fixedly connected with a push plate, the bottom middle end of the workbench is provided with a through hole, the push plate passes through the through hole and is connected to the bottom of the placement seat, and the top of the top plate is fixedly installed with a delivery mechanism. The utility model adopts the above structure, and the electric push rod works to drive the push plate to rise and fall, and then drive the placement seat to rise and fall, so as to achieve the purpose of facilitating the staff to put in or take out steel structure components.

[0005] Although the above-mentioned device can perform alkaline and acid tests during use, its overall testing period still has certain defects. During its use, it is usually necessary to manually remove the workpiece from the inside of the test pool during the corrosion resistance test, and acidic and alkaline liquids are very likely to cause harm to the human body when splashing onto the human body. It can be seen that it has certain defects and shortcomings as a whole, and therefore needs to be improved. Utility Model Content

[0035] Principle and advantages of use: By setting up a storage mechanism, the steel structure components to be tested can be placed inside the holding net frame during use. At this time, the first motor can be started to drive the screw rod to drive the slider to slide inside the transverse rail frame, so that the left and right movable displacement of the holding net frame can be adjusted left and right. By adjusting the left and right displacement of the holding net frame, the left and right position of the holding net frame can be flexibly adjusted. At this time, the position of the holding net frame can be flexibly adjusted according to the requirements of acidity and alkalinity testing. At this time, the holding net frame can be placed inside the acid pool or the alkaline pool by starting the telescopic cylinder to contract, so that the device can be flexibly adapted to acidity and alkalinity testing during use. At the same time, during the testing process, the holding net frame can be vibrated by starting the vibration motor to cause the steel structure components inside the holding net frame to be in a vibrating state, which can cause the steel structure material to evenly contact the corrosive liquid, thereby improving the accuracy of its corrosion testing;

When the steel structure needs to be taken out, the telescopic cylinder is started to operate to draw the containing net frame out of the detection box, and then the card block is pulled out of the limit slot by pulling the connecting shaft.

[0037] By setting a circulation machine, the second motor can be started during the detection period. At this time, the acidic liquid or alkaline liquid flows into the bottom of the conveying pipe. By starting the second motor, the auger can be driven by the second motor to rotate. The rotation of the auger can pump the acidic liquid or alkaline liquid from bottom to top. The liquid flows into the alkaline pool and the acidic pool in the detection box through the upper end of the conveying pipe, which can promote the liquid in the acidic pool or alkaline pool to circulate up and down, improve the overall up and down circulation stirring effect, improve the stability and quality during pickling, and avoid the situation where the uneven acidic and alkaline liquids lead to inaccurate corrosion detection;

[0038] By setting up a drying mechanism, during the use of the equipment, after the acid-base corrosion resistance simulation is completed, the telescopic cylinder is started to pull the containing net frame upwards, and the containing net frame can be pulled and moved to the drying air duct inside the drying coil. By starting the hot air blower, the hot air blower generates hot air and discharges the hot air through the drying coil and the drying air duct to the containing net frame.

At this time, the vibration motor can be started to shake the steel structure components, and the solution attached to the steel structure components can be shaken off during the drying period. At the same time, the steel structure components are lifted up, which can increase the contact area between the steel structure components and the hot air, thereby improving the overall hot air drying efficiency of the device. The drying design can avoid water splashing when taking out the steel structure components, and can avoid corrosive liquids from causing harm to the human body.
