DETAILED DESCRIPTION

[0030] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0031] An experimental device based on plasma physics magnetohydrodynamics, such as Figure 1 and Figure 2 As shown, it includes an operating table 1, a baffle 2, a support frame 3, a backflow column 4, a magnetizing mechanism 5 and a water storage mechanism 6. Two baffles 2 are connected to the front side of the upper part of the operating table 1, and two baffles 2 are also connected to the rear side of the upper part of the operating table 1. The top of the operating table 1 is connected to the support frame 3, and the middle position of the upper part of the support frame 3 is connected to the backflow column 4. The backflow column 4 is used to guide the flow direction of the magnetic fluid, so that people can observe the physical phenomena of the magnetic fluid. The support frame 3 is provided with a magnetizing mechanism 5 for enhancing the magnetism of the backflow column 4, and the operating table 1 is provided with a water storage mechanism 6 for releasing water.

[0032] like Figure 1 and Figure 3 As shown, the magnetizing mechanism 5 includes a fixed seat 51, a connecting rod 52, a pressure plate 53, a magnetizing core 54 and a first spring 55. The top of the support frame 3 is connected to the fixed seat 51, and six connecting rods 52 are connected to the fixed seat 51. A pressure plate 53 is slidably connected between the connecting rods 52. The pressure plate 53 slides up and down under the guiding action of the connecting rods 52. A magnetizing core 54 is connected to the middle of the bottom of the pressure plate 53. The pressure plate 53 is forced to move downward, driving the magnetizing core 54 to move downward together. A first spring 55 is connected between the pressure plate 53 and the connecting rods 52.

[0033] like Figure 1 and Figure 4 As shown, the water storage mechanism 6 includes a water reservoir 61, a water outlet pipe 62 and a support seat 63. The water reservoir 61 is connected to the top of the operating table 1. The water reservoir 61 is filled with experimental water, which is convenient for people to observe the state of the magnetic fluid in the water. The right side of the water reservoir 61 is connected to the water outlet pipe 62. The water outlet pipe 62 can drain the water in the water reservoir 61, which is convenient for people to clean the water reservoir 61. Two support seats 63 are connected to the operating table 1. The support seats 63 are connected to the water outlet pipe 62, and the support seats 63 can support the water outlet pipe 62.

[0034] In the laboratory or teaching activities, when it is necessary to conduct physical experiments on magnetic fluid, the device can be used. First, the magnetic fluid is introduced into the backflow tube with a dropper or other tools, and then the pressure plate 53 is pressed downward, so that the pressure plate 53 drives the magnetizing core 54 to move downward and insert into the backflow column 4 under the guidance of the connecting rod 52. When the pressure plate 53 is pressed downward, the first spring 55 is squeezed, so that the first spring 55 is deformed. Then, the state of the magnetic fluid flowing upward on the backflow column 4 is observed by adjusting the downward movement distance of the magnetizing core 54, and the magnetic fluid is observed and data is recorded. After the experiment on the backflow column 4 is completed, the pressure plate 53 is released to restore the first spring 55, so that the pressure plate 53 is pushed to move upward and reset under the action of the first spring 55;

[0035] When it is necessary to conduct an experimental observation on the state of the magnetic fluid in water, firstly, the water pipe in the water reservoir 61 is blocked by using a tool, and then water is injected into the water reservoir 61. After the injection is completed, the magnetic fluid on the backflow column 4 or a new magnetic fluid can be put into the water reservoir 61. By observing the state of the magnetic fluid in water, the changes of the magnetic fluid are observed and data is recorded. After the experiment is completed, the water outlet pipe 62 is opened to guide the water inside the water reservoir 61, so as to facilitate the cleaning of the water reservoir 61 and facilitate people to conduct experiments next time.

[0036] To summarize, by pressing the pressure plate 53 to drive the magnetizing core 54 to move up and down, the positional relationship between the magnetizing core 54 and the backflow column 4 is adjusted, so that people can observe the state of the magnetic fluid on the backflow column 4. At the same time, water can be injected into the water reservoir 61, and then the magnetic fluid can be introduced into the water to observe the state of the magnetic fluid in the water, which makes it convenient for people to conduct multi-scenario experiments on magnetic fluids, reduces the replacement of experimental equipment, and thus reduces the experimental cost and time.

[0037] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes a feeding mechanism 7, which includes a base 71, a charging barrel 72, a glass tube 73 and a suction ball 74. The base 71 is connected to the top rear side of the operating table 1, and the top of the base 71 is connected to the charging barrel 72. The charging barrel 72 is filled with magnetic fluid for experiments, and the inside of the charging barrel 72 is connected to the glass tube 73, and the glass tube 73 is connected to the suction ball 74. Pressing the suction ball 74 allows the magnetic fluid in the charging barrel 72 to be sucked out through the glass tube 73 and introduced into the backflow column 4 for observation and experiment.

[0038] In order to facilitate people to add magnetic fluid and reduce the pollution of the experimental environment caused by accidental spillage of magnetic fluid, magnetic fluid for experiment can be added into the loading bucket, and the suction ball 74 can be repeatedly pressed to make the glass tube 73 suck out the magnetic fluid in the loading bucket 72, and then accurately introduce it into the backflow column 4. In summary, by repeatedly pressing the suction ball 74, the glass tube 73 can accurately guide the magnetic fluid in the loading bucket 72, which can effectively prevent the magnetic fluid from being spilled and wasted when adding the magnetic fluid for experiment, thereby polluting the experimental environment.

[0039] like Figure 1 , Figure 7 and Figure 8 As shown, it also includes a sliding mechanism 8, which includes a guide frame 81, a placement box 82 and a handle 83. The outer wall of the water reservoir 61 is connected to the guide frame 81, and a placement box 82 is slidably connected to the guide frame 81. The placement box 82 is used to place various magnets to adsorb the magnetic fluid in the water reservoir 61 and observe the state of the magnetic fluid in the water. The front side of the placement box 82 is connected to a handle 83, and the handle 83 is provided with an anti-slip groove, which can increase the friction when in contact with the user's hand, and prevent slipping and difficulty in operation.

[0040] In order to further observe the state of the water magnetic fluid under the influence of magnetic force in the water, a magnet is placed in the placement box 82, and then the placement box 82 is driven by the handle 83 to slide on the guide frame 81, so that the placement box 82 drives the magnet to slide along the outer wall of the water reservoir 61, and the magnetic force affects the magnetic fluid in the water reservoir 61. In summary, by placing a magnet in the placement box 82, and then driving the placement box 82 to move along the guide frame 81 by the handle 83, the effect of facilitating people to observe the state of the magnetic fluid in the water is achieved.

[0041] like Figure 1 and Fig. 9 As shown, a protective mechanism 9 is included, and the protective mechanism 9 includes a connecting frame 91, a connecting ring 92 and a protective sleeve 93. Two connecting frames 91 are connected to the bottom of the support frame 3. The connecting frame 91 can further fix the glass tube 73 to prevent the glass tube 73 from being accidentally touched during the experiment, causing the glass tube 73 to shift and causing the magnetic fluid to overflow and pollute the experimental environment. The lower parts of the two connecting frames 91 are connected to connecting rings 92, and protective sleeves 93 are connected between the connecting rings 92. The protective sleeves 93 are connected to the glass tube 73, and the protective sleeves 93 are able to protect the glass tube 73.

[0042] In order to effectively prevent the accidental spillage of magnetic fluid caused by accidental touching of the glass tube 73 during the experiment, the protective cover 93 is covered with the glass tube 73 through the connecting ring 92 on the connecting frame 91, so as to further protect and fix the glass tube 73. In summary, the glass tube 73 is connected by the protective cover 93, so as to further fix and protect the glass tube 73, which effectively solves the problem of accidental touching of the glass tube 73, causing the glass tube 73 to break and shift, and then causing the magnetic fluid to accidentally spill and pollute the experimental environment.

[0043] like Figure 1 and Fig.10 As shown, it also includes a limiting mechanism 10, which includes a sliding rod 101, a clamping plate 102 and a second spring 103. The left and right sides of the placement box 82 are slidably connected with the sliding rods 101, and the two sliding rods 101 are connected with clamping plates 102. The two clamping plates 102 are close to and away from each other, and can clamp and adjust magnets of different types and sizes, which is convenient for people to perform experimental operations. The second spring 103 is connected between the side where the two clamping plates 102 are away from each other and the placement box 82, and the second spring 103 can apply a thrust to the clamping plate 102, so that the clamping plate 102 can adapt and clamp the magnet, which is convenient for people to operate.

[0044] In order to better adapt to magnets of different sizes so that the magnets will not shake when following the placement box 82 to move, the two clamps 102 can be adjusted by pulling. The clamps 102 will move backward and backward under the guidance of the sliding rod 101, so as to clamp and adapt magnets of different sizes. During adjustment, the clamps 102 will squeeze the second spring 103, so that the second spring 103 will deform. Then, under the action of the second spring 103, the two clamps 102 will always maintain a force close to each other, so as to clamp and adapt the magnets in the placement box 82. In summary, through the cooperation of the clamps 102 and the second spring 103, the clamps 102 can adapt and clamp the magnets in the placement box 82, so that when people slide the placement box 82, the magnets will not shake in the placement box 82, thereby affecting the experimental effect.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
