[0026] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0027] Embodiment 1
[0028] A typical implementation of the present utility model is as follows Figure 1 and Figure 2 As shown, a floating dry-wet alternating anti-corrosion performance experimental device includes a floating platform 1. The cross-section of the floating platform 1 is a circular ring structure. A plurality of buoy interfaces 2 are opened on the lower surface of the floating platform 1. The plurality of buoy interfaces 2 are arranged in a ring along the bottom of the floating platform 1. The buoy interfaces 2 are threadedly connected to buoys 3, so that the floating platform 1 is floated on the water surface by using the buoys 3.
[0029] like Figure 3 As shown, a thread matching the float interface 2 is arranged on the top of the float 3, and the float 3 is hollow inside. Water can be added to the float 3 according to the weight carried by the device to adjust the buoyancy of the device so that it floats on the water.
[0030] A circular through hole is opened at the axis of the floating platform 1, and a sleeve 4 is placed in the circular through hole. The sleeve 4 is a cylindrical structure, and the outer diameter of the sleeve 4 is smaller than the inner diameter of the circular through hole, so that the sleeve 4 can move along the axis direction of the circular through hole.
[0031] The top of the sleeve 4 is open and the bottom is closed. The side wall of the sleeve 4 is surrounded by a plurality of parallel support rods. The two ends of the support rods are respectively connected to the top and the bottom of the sleeve 4. There is a set distance between two adjacent support rods.
[0032] A lifting device is provided on the upper surface of the floating platform 1, and the lifting device is connected to the sleeve 4. The sleeve 4 is lifted by the lifting device. Specifically, the lifting device includes a bracket 5. Two brackets 5 are vertically arranged on the upper surface of the floating platform 1, located on both sides of the circular through hole. A rotating shaft 6 is provided on the top of the bracket 5. The two ends of the rotating shaft 6 are rotatably connected to the two brackets 5 through bearings respectively. One end of the rotating shaft 6 passes through the bracket 5 and is fixedly connected with a handle 7. The rotating shaft 6 can be driven to rotate by the handle 7. A latch 8 is provided on the handle 7. A fixing hole is opened on the bracket 5 close to the handle 7. The fixing hole and the latch 8 are arranged correspondingly. One end of the latch 8 can be inserted into the fixing hole, so as to fix the handle 7 and thereby limit the rotation of the rotating shaft 6.
[0033] A winder 9 is fixedly connected to the rotating shaft 6. Two winders 9 are provided and are symmetrically arranged between the two brackets 5. The spacing between the two winders 9 is the same as the diameter of the sleeve 4. A cable 10 is wound around the winder 9. One end of the cable 10 is fixedly connected to the winder 9, and the other end is connected to the top of the sleeve 4.
[0034] The rotating shaft 6 is rotated. Under the action of the winder 9 and the cable 10, the sleeve 4 follows the rotation of the rotating shaft 6 to perform lifting and lowering movements. A test piece is placed in the sleeve 4, thereby simulating the dry-wet alternation process of the test piece in water and air.
[0035] Since some test pieces are small in size, they are prone to displacement and tilting during the test. In order to avoid the above phenomenon affecting the test results, a plurality of limiters 11 are also provided on the floating platform 1. Specifically, a plurality of limit holes 12 are opened on the outer circumferential surface of the floating platform 1. The plurality of limit holes 12 are evenly arranged around the outer circumferential surface of the floating platform 1. The limit holes 12 extend to the inner circumferential surface of the floating platform 1. The limiter 11 is inserted into the limit hole 12. The limiter 11 is threadedly connected to the limit hole 12. Figure 4 As shown, the limiter 11 is an L-shaped structure, the length of the limiter 11 is greater than the distance between the outer circular surface and the inner circular surface of the floating platform 1, one end of the limiter 11 is inserted into the limit hole 12 from the outer circular surface of the floating platform 1, and extends from the inner circular surface of the floating platform 1, the side wall of the sleeve 4 is composed of a plurality of support rods, and one end of the limiter 11 extends into the interior of the sleeve 4 from the gap between the support rods, thereby limiting the position of the test piece inside the sleeve 4.
[0036] When in use, first place the device on a horizontal plane, put the test piece into the sleeve 4, fix the upper part of the sleeve 4 with one end of the cable 10, and fix the other end of the cable 10 on the winder 9, then put the sleeve 4 into the circular through hole in the middle of the floating platform 1. Some test pieces may be small in size and easily move or fall over, so the test piece can be further constrained by passing the limiter 11 through the limit hole 12.
[0037] Secondly, before putting it into the water, weigh or estimate the weight of the device at this time, use the balance principle to calculate the required buoyancy, select the number of floats 3 reasonably according to the buoyancy, and then symmetrically distribute them and install them on the floating platform 1 through the float interface 2. The buoyancy can also be further adjusted by adding water to the float 3, and then the entire device is placed in the water to make it float on the water surface.
[0038] Finally, the range of the splash zone is determined, and the sleeve 4 is raised and lowered in the splash zone by rotating the shaft 6 clockwise and counterclockwise, driving the specimen to rise and fall together, and fixing the height of the sleeve 4 by the latch 8. According to the test specifications for dry-wet alternation, the sleeve 4 is raised and lowered at regular intervals, and the specimen is repeatedly alternated in water and air to simulate the dry-wet alternation process.
[0039] The experimental device provided by the utility model can be directly used on site without the need for a laboratory to simulate the on-site environment, thereby improving the accuracy of the experimental results.

[0042] A limiter 11 is threadedly connected to the outer circumferential surface of the floating platform 1 , and one end of the limiter 11 penetrates through the side wall of the floating platform 1 and extends to the interior of the sleeve 4 .
[0043] A lifting device is fixedly connected to the upper surface of the floating platform 1, and the lifting device includes two brackets 5, which are symmetrically arranged on both sides of the circular through hole. A rotating shaft 6 is rotatably connected to the top of the two brackets 5. One end of the rotating shaft 6 passes through the bracket 5 and is fixedly connected to a driven sprocket 13. A motor 14 is also provided on the bracket 5 close to the driven sprocket 13. The motor 14 is located directly below the driven sprocket 13. A driving sprocket 15 is fixedly connected to the output shaft of the motor 14. A chain 16 is connected between the driving sprocket 15 and the driven sprocket 13, so that the rotating shaft 6 is driven to rotate through the motor 14.
