DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.

[0027] To solve the above problems, as shown in Figure 1 and Figure 3 A hanging piece device according to an embodiment of the present application comprises a support frame 1 and a bearing plate 2. The support frame 1 is adapted to be arranged in an autoclave, and the support frame 1 is arranged in a spiral structure. The bearing plate 2 is arranged in multiple, and the multiple bearing plates 2 are arranged on the support frame 1 and distributed from one end to the other end of the spiral direction of the support frame 1. The bearing plate 2 is used to arrange a sample 3.

[0028] Among them, the bearing plate 2 is arranged vertically, and each bearing plate 2 is arranged with multiple samples 3. In order to prevent the adjacent two bearing plates 2 from overlapping or interfering with each other, the included angle between the adjacent two bearing plates 2 is 60 degrees.

[0029] In this embodiment, the flow rate of seawater solution in the autoclave follows the formula:

[0030] Wherein, v is the seawater speed, ω is the angular velocity, r is the radius (the horizontal straight line distance between the center axis of the kettle body 11 and each place in the kettle body 11), and ε is the damping coefficient.

[0031] The plurality of bearing plates 2 are distributed from one end to the other end of the spiral direction of the support frame 1, that is, the distances between the plurality of bearing plates 2 and the central axis of the autoclave are all different, and according to the above-mentioned flow rate calculation formula, the flow rates of the seawater solution in the regions where the plurality of bearing plates 2 are located are also all different.

[0032] In summary, by setting the support frame 1 as a spiral structure and distributing the plurality of bearing plates 2 from one end to the other end of the spiral direction of the support frame 1, the distances between the plurality of bearing plates 2 and the central axis of the autoclave are all different, and thus the flow rates of the seawater solution in the regions where the plurality of bearing plates 2 are located are also different. In a process of one experiment, the corrosion data of the sample in the plurality of seawater solutions with different flow rates can be obtained, thereby accelerating the experimental process. At the same time, by setting the support frame 1 as a spiral structure and distributing the plurality of bearing plates 2 from one end to the other end of the spiral direction of the support frame 1, the bearing plates 2 can be distributed from the outside of the support frame 1 to the inside of the support frame 1, which is convenient for setting more bearing plates 2, and the bearing plates 2 are used for setting the samples 3, so it is convenient for setting more samples 3. In addition, the plurality of bearing plates 2 are arranged at an angle, which can prevent the adjacent two bearing plates 2 from overlapping each other and avoid that the bearing plates 2 shield the samples 3 and affect the experimental results.

[0033] Optionally, as shown in Figure 2 , the hanging piece device further comprises a plurality of speed change mechanisms 4, and the plurality of speed change mechanisms 4 are distributed from one end to the other end of the spiral direction of the support frame 1, and at least one speed change mechanism 4 is arranged between the adjacent two bearing plates 2.

[0034] Among them, the speed change mechanism 4 is used for reducing the speed of the seawater solution. When no speed change mechanism 4 is arranged, only the plurality of bearing plates 2 are spirally distributed, and due to the small resistance, the flow rate difference of the seawater solution in the regions where the plurality of bearing plates 2 are located is small, and the corrosion effects of the seawater solutions with different flow rates on the samples 3 are difficult to distinguish.

[0035] In this embodiment, the speed change mechanism 4 is arranged between the adjacent two bearing plates 2, and the seawater solution is reduced in speed after passing through the speed change mechanism 4 in the flowing process. Thus, the flow rate difference of the seawater solution in the regions where the adjacent two bearing plates 2 are located can be increased, and the corrosion effects of the seawater solutions with different flow rates on the samples 3 can be distinguished.

[0036] Optionally, as shown in Figure 2 , the speed change mechanism 4 comprises a first support rod 41 and a damping structure 42, the first support rod 41 is vertically arranged and connected with the support frame 1, and the damping structure 42 is provided with a plurality of damping structures 42, and the plurality of damping structures 42 are all arranged on the first support rod 41.

[0037] The plurality of damping structures 42 are sleeved on the first support rod 41.

[0038] In the embodiment, the damping structure 42 is arranged so that the flow rate of the seawater solution is closer to the value calculated by the flow rate formula, which can make the obtained experimental data more accurate and facilitate the research on new materials. At the same time, according to the flow rate formula, the flow rate of the seawater solution in the area where the bearing plate 2 is located can be directly obtained by calculation, without the need to set up a flow rate measuring mechanism, thereby simplifying the structure of the coupon device.

[0039] Optionally, as shown in Figure 1 The support frame 1 comprises a second support rod 11 and a limiting mechanism 12. The second support rod 11 is arranged vertically, and the limiting mechanism 12 is arranged on the second support rod 11. The limiting mechanism 12 is arranged in a spiral structure, and the bearing plate 2 is detachably assembled on the limiting mechanism 12.

[0040] In the embodiment, during the experiment, the test sample 3 can be arranged on the bearing plate 2 first, and then the bearing plate 2 is assembled on the limiting mechanism 12. After the experiment is completed, the bearing plate 2 can be removed from the limiting mechanism 12 first, and then the test sample 3 is removed from the bearing plate 2. In this way, the test sample 3 can be conveniently arranged on the coupon device and removed from the coupon device. At the same time, the bearing plate 2 is detachably assembled on the limiting mechanism 12, which simplifies the assembly process of the coupon device, thereby facilitating the experimental operation.

[0041] Optionally, as shown in Figure 1 , Figure 4 and Figure 5 The limiting mechanism 12 comprises a first support plate 121 and a second support plate 122. The first support plate 121 and the second support plate 122 are both arranged in a planar spiral structure, and the spiral directions of the first support plate 121 and the second support plate 122 are the same. The first support plate 121 and the second support plate 122 are both sleeved on the second support rod 11.

[0042] The bearing plate 2 is arranged between the first support plate 121 and the second support plate 122. The first support plate 121 is provided with a first mounting groove 1211 matched with the front side structure of the bearing plate 2, and the second support plate 122 is provided with a second mounting groove 1221 matched with the rear side structure of the bearing plate 2.

[0043] The second support rod 11 is arranged in a cylindrical structure. The first support plate 121 is provided with a first assembly hole relative to the second support rod 11, and the second support plate 122 is provided with a second assembly hole relative to the second support rod 11. The bearing plate 2 is arranged in a rectangular plate structure. The first mounting groove 1211 and the second mounting groove 1221 are both arranged in a "L" shape. At the same time, the first support rod 41 passes through the first support plate 121 and the second support plate 122 in sequence.

[0044] In the embodiment, when assembling the second support rod 11, the first support plate 121, the second support plate 122 and the bearing plate 2, the second support rod 11 is arranged, the first support plate 121 is sleeved on the second support rod 11 through the first assembly hole; the bearing plate 2 is arranged vertically, and the front structure of the bearing plate 2 is arranged into the first mounting groove 1211; the second support plate 122 is sleeved on the second support rod 11 through the second assembly hole, and the rear structure of the bearing plate 2 is arranged into the second mounting groove 1221. Thus, the front structure of the bearing plate 2 is limited by the first support plate 121, and the rear structure of the bearing plate 2 is limited by the second support plate 122, so that the bearing plate 2 can be prevented from being separated from the support frame 1 in the experiment process, and adverse effects on the experiment are avoided.

[0045] Alternatively, the first support plate 121 and the second support plate 122 are both provided in plurality, and the plurality of first support plates 121 and the second support plates 122 are arranged alternately in the vertical direction on the second support rod 11.

[0046] Since the first support plate 121 only limits the front structure of the bearing plate 2, and the second support plate 122 only limits the rear structure of the bearing plate 2, when the first support plate 121 and the second support plate 122 are arranged at the upper and lower ends of the bearing plate 2 respectively, only the front side of the upper end and the rear side of the lower end of the bearing plate 2 can be limited. When the bearing plate 2 is arranged in this way, the structure of the bearing plate 2 is not stable and is easy to be separated from between the first support plate 121 and the second support plate 122.

[0047] In the embodiment, the plurality of first support plates 121 and the second support plates 122 are arranged alternately in the vertical direction, and specifically, three first support plates 121 and three second support plates 122 can be arranged, one first support plate 121 and one second support plate 122 are arranged at the lower end of the second support rod 11, one first support plate 121 and one second support plate 122 are arranged at the middle of the second support rod 11, and one first support plate 121 and one second support plate 122 are arranged at the upper end of the second support rod 11, so that the front and rear sides of the upper, middle and lower three parts of the bearing plate 2 are all limited.

The end of the second support rod 11 is arranged in the first positioning groove 1231.

[0049] Among them, the third support plate 123 is arranged as a plane spiral structure, and the spiral direction of the third support plate 123 is the same as that of the first support plate 121 and the second support plate 122. At the same time, the third support plate 123 is sleeved on the second support rod 11. In addition, the second positioning groove 1232 is arranged on the third support plate 123, and the end of the first support rod 41 is arranged in the second positioning groove 1232.

[0050] In this embodiment, the third support plate 123 arranged at the upper end of the bearing plate 2 has the first positioning groove 1231 located on the lower surface of the bearing plate 2, and the third support plate 123 arranged at the lower end of the bearing plate 2 has the first positioning groove 1231 located on the upper surface of the bearing plate 2. The third support plate 123 is arranged on the second support rod 11, and the upper and lower ends of the bearing plate 2 are limited by the two third support plates 123, which can ensure the stability of the structure of the bearing plate 2 and avoid adverse effects on the experiment. At the same time, the third support plate 123 is arranged as a plane spiral structure, which can reduce the material of the third support plate 123 compared with a disc structure, reduce the weight of the hanging piece device, and save the experimental cost.

[0051] Optionally, as shown, Figure 1 As shown, the support frame 1 further comprises a nut 13, the support frame 1 further comprises a nut 13, the nut 13 is provided with a plurality of, and the upper and lower ends of the first support plate 121, the second support plate 122 and the third support plate 123 are provided with the nut 13, and the nut 13 is sleeved on the second support rod 11.

[0052] Among them, since the second support rod 11 is provided with a plurality of, the first support plate 121, the second support plate 122 and the third support plate 123 are simultaneously sleeved on the plurality of second support rods 11, and the upper and lower ends of the connection between the second support rod 11 and the first support plate 121, the second support plate 122 and the third support plate 123 are provided with at least one nut 13, and the second support rod 11 is provided with a thread at the connection with the first support plate 121, the second support plate 122 and the third support plate 123.
