[0002] Biomedical materials are new high-tech materials used for diagnosing, treating, repairing or replacing human tissues, organs or enhancing their functions. With the progress of preparation processes and technologies, new bio-metallic materials are constantly emerging. The metals studied and industrialized more are magnesium-based metals and alloys. Magnesium not only has excellent mechanical properties and biocompatibility, but also can be absorbed and degraded in the human body. After healing, there is no need for a second operation to remove it. However, magnesium alloys belong to active metals, and the degradation rate in the body is uncontrollable. Researchers are committed to studying the corrosion properties of magnesium alloys. In traditional corrosion test devices, the corrosion medium is static, and the electrochemical corrosion and immersion corrosion tests are two separate devices. This patent designs a test device with adjustable flow rate of the corrosion medium, which can not only conduct immersion tests, but also realize electrochemical corrosion tests by adding electrode contact holes.

[0003] When the existing corrosion test device conducts real-time electrochemical corrosion measurement on metal materials, since the corrosive substance is static, it is impossible to completely immerse the metal materials in the corrosion medium, so it is necessary to adjust the position of the corrosion medium multiple times to completely immerse the corrosion medium, which further increases the steps of the corrosion medium in the electrochemical corrosion experiment, making the experiment cumbersome. Summary of the Utility Model

[0004] In order to overcome the deficiencies that when the existing corrosion test device conducts real-time electrochemical corrosion measurement on metal materials, since the corrosive substance is static, it is impossible to completely immerse the metal materials in the corrosion medium, so it is necessary to adjust the position of the corrosion medium multiple times to completely immerse the corrosion medium, which further increases the steps of the corrosion medium in the electrochemical corrosion experiment, making the experiment cumbersome, the embodiment of the present application provides a corrosion test device with adjustable flow rate, including a device body and an installation circle. The installation circle is arranged inside the device body. An immersion tank is arranged inside the device body. A plurality of water inlet holes are evenly opened on one side of the immersion tank. A water inlet pipe is fixedly installed inside the water inlet holes. One end of the water inlet pipe is fixedly installed with a water collection tank. One end of the water collection tank is fixedly connected with a main water inlet pipe. One end of the main water inlet pipe is fixedly connected with a control device.

[0005] The technical solution adopted by the embodiment of the present application to solve its technical problems is:

[0006] A corrosion test device with adjustable flow rate, including a device body and an installation circle. The installation circle is arranged inside the device body;

[0007] Among them, an impregnation tank is provided inside the device body. A plurality of water inlet holes are evenly opened on one side of the impregnation tank. A water inlet pipe is fixedly installed inside the water inlet hole. One end of the water inlet pipe is fixedly installed with a water collection tank. One end of the water collection tank is fixedly connected to a main water inlet pipe. One end of the main water inlet pipe is fixedly connected to a control device.

[0008] In a possible implementation manner, one end of the control device is fixedly connected to a main water outlet pipe. One end of the main water outlet pipe is fixedly connected to a water storage tank.

[0009] In a possible implementation manner, a plurality of water outlet pipes are evenly connected to one side of the water storage tank. One end of the water outlet pipe is fixedly connected to one side of the device body.

[0011] In a possible implementation manner, a push rod is fixedly connected to the middle of the bottom of the installation circle. One end of the push rod is slidably connected to a lifting rod.

[0012] In a possible implementation manner, one end of the lifting rod is fixedly connected to a cylinder. The bottom of the cylinder is fixed to the bottom of the impregnation tank.

[0013] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0014] 1. By starting the control device, the internal water is input into the main water inlet pipe connected at one end. The main water inlet pipe allows the internal water to enter the water collection tank at one end. By controlling the pressure inside the water collection tank through the control device, the internal water is then made to enter the water inlet pipe on one side. The water inlet pipe uses the internal pressure to pass the water through the water inlet holes at one end and flow into the impregnation tank, thereby impregnating the installation circle inside. Since there are multiple water inlet holes for water to enter the impregnation tank, when water enters the impregnation tank, the control device controls the main water outlet pipe at one end to suck water in. Thus, the suction force inside the main water outlet pipe sucks the water inside the water storage tank at one end. After the water inside the water storage tank is sucked out, the water inside the impregnation tank is discharged through the plurality of water outlet pipes fixedly connected to one side. Then, the control device conveys the sucked water back into the main water inlet pipe, thereby making the water inside the impregnation tank flow. When the internal metal sample is being impregnated, it is corroded more thoroughly.

Start the cylinder at the bottom of the impregnation tank to drive the lifting rod at one end to move upward, thereby driving the push rod at one end to move upward, driving the mounting circle at the top to move upward, insert the components corresponding to the working electrode, counter electrode and reference electrode, start the cylinder to drive the lifting rod at the upper end to move downward, thereby driving the push rod at one end to move downward, driving the mounting circle at the top to move downward, and immerse the components at the upper end into the impregnation tank. Soak them with the water inside to corrode them more thoroughly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present application are to solve the problems in the above background technology, and the general idea is as follows:

[0022] Embodiment 1:

[0023] This embodiment introduces the specific structure of the corrosion test device with adjustable flow rate. Specifically, refer to Figures 1 - 4 as shown, it includes a device body 1 and a mounting circle 2. The mounting circle 2 is arranged inside the device body 1. An impregnation tank 5 is arranged inside the device body 1. A plurality of water inlet holes 3 are evenly opened on one side of the impregnation tank 5. A water inlet pipe 4 is fixedly installed inside the water inlet hole 3. One end of the water inlet pipe 4 is fixedly installed with a water collection tank 6. One end of the water collection tank 6 is fixedly connected with a total water inlet pipe 7. One end of the total water inlet pipe 7 is fixedly connected with a control device 8;

[0024] Among them, when it is necessary to impregnate the device on the top of the mounting circle 2, the internal water is input into the water inlet main pipe 7 connected to one end by starting the control device 8. The water inlet main pipe 7 allows the internal water to enter the water collection tank 6 at one end. The pressure inside the water collection tank 6 is controlled by the control device 8, so that the internal water enters the water inlet pipe 4 on one side. The water inlet pipe 4 uses the internal pressure to pass the water through the water inlet holes 3 at one end and flow into the impregnation tank 5, and then impregnates the mounting circle 2 inside. Since there are multiple water inlet holes 3 for water to enter the impregnation tank 5, the samples on the top of the mounting circle 2 are fully corroded;

[0025] At the same time, when water enters the impregnation tank 5, the water outlet main pipe 9 at one end is controlled by the control device 8 to absorb water inward. Thus, the suction force inside the water outlet main pipe 9 sucks the water inside the water storage tank 10 at one end. After the water inside the water storage tank 10 is sucked out again, the water inside the impregnation tank 5 is discharged through the multiple water outlet pipes 11 fixedly connected to one side. Then, the control device 8 conveys the sucked water into the water inlet main pipe 7. Furthermore, the water inside the impregnation tank 5 is flowing, so that the samples inside are more fully corroded when being impregnated;

[0026] By adopting the above technical solutions:

[0027] When the above design needs to impregnate the device on the top of the mounting circle 2, the internal water is input into the water inlet main pipe 7 connected to one end by starting the control device 8. The water inlet main pipe 7 allows the internal water to enter the water collection tank 6 at one end. The pressure inside the water collection tank 6 is controlled by the control device 8, so that the internal water enters the water inlet pipe 4 on one side. The water inlet pipe 4 uses the internal pressure to pass the water through the water inlet holes 3 at one end and flow into the impregnation tank 5, and then impregnates the mounting circle 2 inside;

[0028] Since there are multiple water inlet holes 3 for water to enter the impregnation tank 5, when water enters the impregnation tank 5, the water outlet main pipe 9 at one end is controlled by the control device 8 to absorb water inward. Thus, the suction force inside the water outlet main pipe 9 sucks the water inside the water storage tank 10 at one end. After the water inside the water storage tank 10 is sucked out again, the water inside the impregnation tank 5 is discharged through the multiple water outlet pipes 11 fixedly connected to one side. Then, the control device 8 conveys the sucked water into the water inlet main pipe 7. Furthermore, the water inside the impregnation tank 5 is flowing, so that the samples inside are more fully corroded when being impregnated.

[0029] Embodiment 2:

[0030] Based on Embodiment 1, this embodiment introduces the specific structure of the mounting circle 2. Three motor contact holes are fixedly connected to the top of the mounting circle 2, namely the working electrode 12, the counter electrode 13 and the reference electrode 14;

[0031] Among them, when a corrosion experiment needs to be carried out on the component, the cylinder 15 at the bottom of the dipping tank 5 is started to drive the lifting rod 17 at one end to move upward, thereby driving the push rod 16 at one end to move upward, driving the mounting circle 2 at the top to move upward, inserting the components corresponding to the working electrode 12, the counter electrode 13 and the reference electrode 14, starting the cylinder 15 to drive the lifting rod 17 at the upper end to move downward, thereby driving the push rod 16 at one end to move downward, driving the mounting circle 2 at the top to move downward, putting the upper component into the dipping tank 5, and soaking it with the water inside, so as to corrode more fully;

[0032] The operation steps of the user are as follows:

[0033] S1. When a corrosion experiment needs to be carried out on the component, start the cylinder 15 at the bottom of the dipping tank 5 to drive the lifting rod 17 at one end to move upward, thereby driving the push rod 16 at one end to move upward, driving the mounting circle 2 at the top to move upward, and insert the components corresponding to the working electrode 12, the counter electrode 13 and the reference electrode 14;

[0034] S2. When the component is inserted into the corresponding motor contact hole, start the cylinder 15 to drive the lifting rod 17 at the upper end to move downward, thereby driving the push rod 16 at one end to move downward, driving the mounting circle 2 at the top to move downward, and put the upper component into the dipping tank 5;

[0035] S3. When the mounting circle 2 enters the dipping tank 5, start the control device 8 to input the internal water into the water inlet main pipe 7 connected to one end. The water inlet main pipe 7 allows the internal water to enter the water collection tank 6 at one end. Control the pressure inside the water collection tank 6 through the control device 8, so that the internal water enters the water inlet pipe 4 on one side. The water inlet pipe 4 uses the internal pressure to make the water flow through the water inlet hole 3 at one end and into the dipping tank 5, and then impregnate the mounting circle 2 inside. When water enters the dipping tank 5, control the water outlet main pipe 9 at one end to absorb water inward through the control device 8, so that the suction force inside the water outlet main pipe 9 sucks the water inside the water storage tank 10 at one end. After the water inside the water storage tank 10 is sucked out, the water inside the dipping tank 5 is discharged through the multiple water outlet pipes 11 fixedly connected to one side. Then the control device 8 conveys the sucked water into the water inlet main pipe 7. Thus, the water inside the dipping tank 5 is flowing, making the sample inside corrode more fully when being impregnated.

[0036] By adopting the above technical solution:

[0037] When the above design requires a corrosion experiment on the component, the cylinder 15 at the bottom of the dipping tank 5 is started to drive the lifting rod 17 at one end to move upward, thereby driving the push rod 16 at one end to move upward, driving the mounting circle 2 at the top to move upward, inserting the components corresponding to the working electrode 12, the counter electrode 13 and the reference electrode 14. Then start the cylinder 15 to drive the lifting rod 17 at the upper end to move downward, thereby driving the push rod 16 at one end to move downward, driving the mounting circle 2 at the top to move downward, and placing the upper component into the dipping tank 5. Soak it with the water inside, so as to corrode more thoroughly.

[0038] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limiting the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
