Description

Technical Field

[0001] This invention relates to the field of performance testing technology for steel structural components, and in particular to an adjustable intelligent load-corrosion coupling testing device. Background Technology

[0002] The marine atmospheric environment refers to the near-shore atmospheric region that is strongly influenced by the ocean. Its core characteristics are high salt spray and high humidity. Sea salt particles generated by the breaking of ocean waves are suspended in the atmosphere. They are not only highly hygroscopic, significantly prolonging the wetting time of material surfaces, but also bring extremely strong corrosiveness. This environment will accelerate the corrosion of metals and the aging of non-metallic materials.

[0003] When conducting marine atmospheric environment resistance tests on steel, components, and nodes in space grid structures, existing test methods often involve directly placing the components in the marine atmospheric environment, subjecting them to the dual coupling effects of environmental loads and corrosion. However, due to the seasonal influence of the marine atmospheric environment, the corrosive capacity of the components cannot be effectively maintained and is extremely unstable, resulting in an extremely long test cycle. Furthermore, the lack of effective monitoring by intelligent sensors has a significant adverse impact on test efficiency and effectiveness. Summary of the Invention

Each of the multiple curved grooves 923 has a sliding block 924 slidably connected within it. Each sliding block 924 has a circular groove, and the inner wall of each groove is rotatably connected to an adjusting screw 925 via an external thread. The end of the adjusting screw 925 closest to the guide tube 916 is bolted to the outside of the push frame 930 on the same side. A locking spring 926 surrounds the outside of each adjusting screw 925. One end of the locking spring 926 is bolted to the outside of the sliding block 924 on the same side, and the other end contacts the outside of the adjusting screw 925. The inner wall of each of the multiple enclosed covers 907 on the side away from the curved grooves 923 is bolted to an arc panel 931. Each arc panel 931 is equipped with a magnet 932. The outer wall of the tube ball component 5... The unit is equipped with multiple symmetrical arc-shaped airbags 933. The arc-shaped airbags 933 are attached to the side opposite to the tube ball component 5. The side of the arc-shaped airbags 933 near the arc panel 931 is bolted to a butt plate 934. A magnet 935 is provided on each butt plate 934. The magnet 935 is attached to the side opposite to the magnet 932 on the same side. A thin tube is provided on each arc-shaped airbag 933.

The output end of the rotary motor 914 is connected to one side of the double-acting screw 913 via a coupling.

[0026] In specific application scenarios, the simulated spraying module 9 is mainly suitable for the simulated spraying stage in the simulated spraying process. Specifically, the simulated spraying module 9 utilizes an arc-shaped nozzle 917, a guide pipe 916, a transmission gear 922, an arc-shaped rack 920, and an arc-shaped slide rail 918 to achieve a 360-degree solution spray on the surface of the tube ball component 5, ensuring that the solution can fully cover the corrosion test areas on the tube ball component 5, thus ensuring the effectiveness of the corrosion test. The adjusting screw 925, the pusher 930, the slide 929, and the rotating shaft 928 allow the arc-shaped nozzle 917 to actively face the weak areas of the tube ball nodes on the tube ball component 5, ensuring that the solution can fully contact the tube ball node areas. Simultaneously, the arc-shaped airbag 933 seals the other side of the sealing cover 907. The oblique spraying of the arc-shaped nozzle 917 reduces the amount of solution splashing onto the non-test area of ​​the tube ball component 5 after contact with the surface, thus reducing the interference of the splashed solution on the experimental results and improving the accuracy and reliability of the test results. The arc panel 931, magnet one 932, butt bend plate 934, magnet two 935 and arc-shaped airbag 933 can isolate the non-test area from the test area on the device, thereby effectively controlling the test range and ensuring that the solution only flows in the test area, improving the accuracy of the test operation and ensuring full contact between the solution and the test part. The replaceable arc-shaped airbag 933 also allows the device to be specifically replaced for tube ball components 5 of different sizes, improving the versatility of the device.

[0027] Reference Figure 9 and Figure 10In a preferred embodiment, the cleaning module 10 includes two symmetrical water storage tanks 1001. The bottom of each water storage tank 1001 is bolted to the inner wall of the bottom of the test chamber 1. Each water storage tank 1001 is located below the support plate 2. Each water storage tank 1001 is equipped with a replenishment pipe 1002. Two symmetrical slots are formed on the side of the test chamber 1 away from the closed door 3. The inner walls of these slots are bolted to the outside of the replenishment pipe 1002 on the same side. Two symmetrical pumps 1003 are bolted to the inner wall of the bottom of the test chamber 1. The output ends of each pump 1003 are connected to the replenishment pipe 1002 on the same side via short pipes. A circular opening is formed on one inner wall of the liquid storage tank 11. A long rod is rotatably connected to the inner wall of the circular opening via a bearing. A stirring paddle 1006 is bolted to the outside of the long rod. A motor 1005 is bolted to the outside of the liquid storage tank 11. The output end of 05 is connected to one side of the long rod via a coupling; both water storage tanks 1001 are equipped with branch pipes 1011, and the end of the branch pipe 1011 away from the water storage tank 1001 is connected to the main infusion pipe 903 on the same side. Both the branch pipe 1011 and the main infusion pipe 903 are equipped with electronic valves 1012. The upper side of the support plate 2 is connected to the control console 1004 by bolts. The side of the control console 1004 near the liquid storage tank 11 is connected to two symmetrical storage tanks 1007 by bolts. The two storage tanks 1007 are equipped with the same three-way pipe 1008. The three-way pipe 1008 is equipped with two symmetrical control valves 1009. The end of the three-way pipe 1008 away from the storage tank 1007 is located inside the liquid storage tank 11. The three-way pipe 1008 is equipped with an infusion pump 1010. The output end of the infusion pump 1010 is connected to the three-way pipe 1008 via a pipe.

[0028] In specific application scenarios, the cleaning module 10 is mainly used in the cleaning process. That is, the cleaning module 10 uses the water storage tank 1001, branch pipe 1011 and electronic valve 1012 to backwash the structural components in the enclosure 907, thereby avoiding the solution from drying and crystallizing on the structural components, causing corrosion and jamming, ensuring the normal operation of the device and improving its service life. At the same time, the storage tank 1007 and the three-way pipe 1008 can replenish and reuse the test materials and water in the solution, reducing material loss and lowering costs while ensuring that the test conditions are not affected.

[0029] Working principle: After opening the closed door 3 and fixing the tube ball component 5 to the fixing part 6, start the linear motor 910. The linear motor 910 drives the closed cover 907 to move to the outside of the tube ball component 5. Rotate the lower closed cover 907 so that the lower closed cover 907 and the upper closed cover 907 surround and align with the outside of the tube ball component 5, so that the tube ball node on the tube ball component 5 is located between the two closed covers 907. Tighten the fixing bolts 908. Start the rotating motor 914 to rotate the double-acting screw 913, which drives the closed cover 907 to move to the weak point of the tube ball node connection on the tube ball component 5. Start the hydraulic rod 7. The output end of the hydraulic rod 7 extends or shortens, thereby applying axial pressure or tensile load to the tube ball component 5. Start the air pump 936. Air pump 936 inflates the arc-shaped airbag 933, causing it to expand and adhere tightly to the outside of the tube ball component 5, thus sealing one side of the sealing cover 907. Rotating the adjusting screw 925 moves it towards the inside of the sealing cover 907 on the sliding block 924, causing the adjusting screw 925 to drive the pusher frame 930 against the inner wall of the push groove 929. This causes the guide pipe 916 to rotate around the rotating shaft 928 on the fixed frame 927, allowing the arc-shaped nozzle 917 connected to the guide pipe 916 to rotate a certain angle towards the tube ball node. The delivery pump 904 is then started, causing the main delivery pipe 903 to deliver the sodium chloride solution from the storage tank 11 to the secondary delivery pipe 906 through the three-way connector 905, and finally through the arc-shaped nozzle... The nozzle 917 sprays onto the surface of the tube ball component 5. The drive motor 921 is activated, causing the arc-shaped rack 920, which meshes with the transmission gear 922, to swing. This causes the curved panel 919 to swing the arc-shaped nozzle 917 on the fixing frame 927, allowing the nozzle 917 to spray the tube ball node area on the tube ball component 5 at a 360-degree angle. Simultaneously, the spraying time, interval, and flow rate are controlled. The intelligent sensor 902 monitors the temperature and concentration of the solution, while the temperature control unit 901 maintains the solution temperature between 17 and 23 degrees Celsius. The solution flowing down the surface of the tube ball component 5 flows down from the drain hole 909 below and eventually drips back into the storage tank 11. After the test is completed, the tube ball component 5 is removed, and the circuit is closed. The electronic valve 1012 on the main infusion pipe 903 is opened, and the electronic valve 1012 on the branch pipe 1011 is started, starting the delivery pump 904. The water in the water storage tank 1001 is delivered to the arc-shaped nozzle 917 and sprayed out, thereby rinsing the structural components in the enclosure 907. After the rinsed liquid enters the storage tank 11, the intelligent sensor 902 monitors the concentration and pH value of the solution. At the same time, the control console 1004 starts the branch pipe 1011 and opens the control valve 1009, delivering the sodium hydroxide solution and hydrochloric acid solution in the two storage tanks 1007 to the storage tank 11 respectively, thereby ensuring that the solution in the storage tank 11 meets the test requirements. The pump 1003 is started, so that the replenishment pipe 1002 replenishes the clean water in the water storage tank 1001.
