Description

Technical Field

[0001] This utility model relates to the field of reinforced concrete testing, and in particular to a device for simulating and observing the corrosion of rusted reinforced concrete structures. Background Technology

[0002] The main inducing factor for the deterioration of the durability of reinforced concrete structures is steel corrosion. Steel corrosion in concrete can be caused by a variety of factors. Carbonation, oxidation and temperature generally have a small effect on steel corrosion, and only have a significant effect under certain special conditions.

[0003] While existing corrosion simulation and observation devices for reinforced concrete structures can simulate corrosion under various environmental conditions, such as carbonization and oxidation, they lack the ability to simulate underwater turbulent environments. This results in certain limitations and a lack of comprehensiveness in experiments.

This device would utilize water pumps. During operation, the left pump would draw water from the tank into the delivery pipe, transport it to the distribution chamber, and then out through the distribution chamber's channel, thus simulating underwater turbulent environments. The right pump would draw water from the glass tank back into the tank through the return pipe, achieving circulation. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment of a corrosion simulation observation device for reinforced concrete structures, including a base plate 1; it also includes a water tank 5, a water pump 6, a water supply pipe 7, a diversion chamber 8, a through channel 9, and a return pipe 10.

One end of the water supply pipe 7 is arranged at the output end of the left water pump 6. A diversion chamber 8 is arranged on the lower left side of the inner surface of the glass box 4, and the diversion... A through groove 9 is provided on the right side surface of the chamber 8. The other end of the water supply pipe 7 passes through the left side wall of the glass box 4 and is connected to the diversion chamber 8. The output end of the water pump 6 on the right side is connected to the return pipe 10. The other end of the return pipe 10 is connected to the water tank 5. By setting the water pump 6, the water pump 6 on the left side can draw water from the water tank 5 into the water supply pipe 7 during operation, transport it to the diversion chamber 8 through the water supply pipe 7, and flow out through the through groove 9 of the diversion chamber 8, thereby simulating the turbulent environment underwater. When the water pump 6 on the right side is operating, it can draw water from the glass box 4 back into the water tank 5 through the return pipe 10, thereby realizing circulation.

[0023] Please see Figures 1-4In this embodiment, the lifting assembly includes a mounting frame 201, a first drive motor 202, a screw 203, and a movable seat 204. The mounting frame 201 is located on the right side of the upper surface of the base plate 1. The first drive motor 202 is located on the upper surface of the mounting frame 201. The output end of the first drive motor 202 passes through the top surface of the mounting frame 201 and is connected to one end of the screw 203. The other end of the screw 203 is rotatably connected to the bottom of the inner surface of the mounting frame 201. The outer surface of the screw 203 is threadedly connected to the movable seat 204. The left side surface of the movable seat 204 is connected to the right side surface of the glass plate 3. By providing the first drive motor 202, its output end can drive the screw 203 to rotate during operation. When the screw 203 rotates, it can drive the threaded movable seat 204 to move up and down, thereby enabling... The glass plate 3 lifts the glass box 4, allowing staff to observe the bottom condition of the reinforced concrete. A limiting frame 11 is installed on the left side of the upper surface of the base plate 1. Limiting rods 12 are connected to the upper and lower ends of the inner surface of the limiting frame 11. A limiting block 13 is slidably connected through the outer surface of the limiting rod 12. The right side surface of the limiting block 13 is connected to the left side surface of the glass plate 3. By setting the limiting rod 12 and the limiting block 13, the limiting block 13 can slide along the surface of the limiting rod 12 when the glass plate 3 is raised and lowered. The limiting rod 12 can restrict the sliding direction of the limiting block 13, thereby improving the stability of the glass plate 3. A positioning frame 14 is set on the upper surface of the glass plate 3. The inner surface of the positioning frame 14 is in contact with the outer surface of the glass box 4. By setting the positioning frame 14, the glass box 4 can be limited to prevent it from shifting and falling.

[0024] Please see Figures 1-3 In this embodiment, three retaining seats 15 are engaged on the upper surface of the rear side wall of the glass box 4. The upper surface of each retaining seat 15 is provided with an arc-shaped gripper 16. The arc-shaped gripper 16 facilitates the positioning and installation of components such as nozzles used in experiments. A mounting plate 17 is located on the left side of the front surface of the glass box 4. A second drive motor 18 is located on the upper surface of the mounting plate 17. A drive gear 19 is located at the output end of the second drive motor 18. A baffle 20 is rotatably connected to the bottom left side of the inner surface of the glass box 4. A driven gear 21 is located on the upper surface of the baffle 20. Gear 19 meshes with driven gear 21. By setting a second drive motor 18, its output end can drive the drive gear 19 to rotate during operation. When the drive gear 19 rotates, it can drive the driven gear 21 meshing with it to rotate synchronously, thereby driving the baffle 20 to adjust its angle, thereby changing the vortex state of the turbulence and improving the diversity of the test. Support legs 22 are set at the corners of the bottom surface of the base plate 1. Shims 23 are set on the bottom surface of the support legs 22. By setting support legs 22 and shims 23, the overall stability of the device can be improved and the test accuracy can be improved.

[0025] During operation, the first drive motor 202 drives the screw 203 to rotate. The screw 203, when rotating, moves the threaded movable seat 204 up and down, causing the glass plate 3 to lift the glass box 4, facilitating observation of the bottom of the reinforced concrete. A limiting rod 12 and a limiting block 13 are installed. When the glass plate 3 rises and falls, the limiting block 13 slides along the surface of the limiting rod 12. The limiting rod 12 restricts the sliding direction of the limiting block 13, thus improving the stability of the glass plate 3's lifting and lowering. By setting a fixed... The frame 14 can limit the glass box 4 to prevent it from shifting and falling. The arc-shaped gripper 16 makes it easy for staff to position and install components such as nozzles used in experiments. The second drive motor 18 can drive the drive gear 19 to rotate during operation. When the drive gear 19 rotates, it can drive the driven gear 21 meshing with it to rotate synchronously, thereby driving the baffle 20 to adjust its angle and change the turbulent vortex state, thus improving the diversity of the experiment. The support legs 22 and the pads 23 can improve the overall stability of the device and improve the accuracy of the experiment.

[0026] Through the above steps, by setting up water pump 6, during operation, the water pump 6 on the left can draw water from inside the water tank 5 into the water supply pipe 7, transport it to the inside of the diversion chamber 8 through the water supply pipe 7, and flow out through the through channel 9 of the diversion chamber 8, thereby simulating the underwater turbulent environment. When the water pump 6 on the right is operating, it can draw water from inside the glass box 4 back into the water tank 5 through the return pipe 10, thereby achieving circulation. This solves the problem that the existing corrosion simulation observation device for reinforced concrete structures does not have the function of simulating the underwater turbulent environment, which leads to certain limitations and incompleteness in the experiment.
