An air inlet box 3 is provided on the inner wall of the side of the experimental machine case 1; a rotating rail 17 is provided at one end of the exhaust pipe 11, and a rotating wheel 5 is provided inside the rotating rail 17. The other end of the rotating wheel 5 is provided with a fan disk 51, and a fan blade seat 2 is provided at the center of the fan disk 51. The cross-section of the fan blade seat 2 is a regular polygon, and fan blades 21 are provided on the sides of the fan blade seat 2, and the other end of the fan blade 21 is in contact with the fan disk 51.

[0030] Specifically, an exhaust pipe 11 is provided at the center of one side of the experimental machine case 1, and an electric control box 12 is provided on one side of the surface where the exhaust pipe 11 of the experimental machine case 1 is located. The exhaust pipe 11 is electrically connected to the electric control box 12, and the exhaust pipe 11 is controlled by the electric control box 12 to extract the heat generated inside the experimental machine case 1; an air outlet 14 is provided on the surface where the exhaust pipe 11 of the experimental machine case 1 is located, and the air outlet 14 is concentrically arranged with the exhaust pipe 11, and the exhaust pipe 11 is connected to the experimental machine case 1 through the air outlet 14; the sides of the two ends of the experimental machine case 1 are provided There are multiple air inlets 13, and the air inlets 13 pass through the side of the experimental machine case 1, and the external cold air flow is introduced into the interior of the experimental machine case 1 through the air inlets 13; the air inlet 13 is provided with an air inlet box 3 on the inner wall of the side of the experimental machine case 1, and the air flow entering the experimental machine case 1 is adjusted by the air inlet box 3, and the wheel 5 can be rotated inside the exhaust pipe 11 through the rotating rail 17, thereby driving the fan disk 51 to rotate synchronously; multiple fan blades 21 can seal the space between the fan blade seat 2 and the fan disk 51, and then seal one end of the exhaust pipe 11.

[0031] A fixing seat 16 is disposed at the inner center of the air outlet 14 , a plurality of connecting plates 15 are evenly disposed between the fixing seat 16 and the air outlet 14 , and a bearing 24 is disposed inside the fixing seat 16 .

[0032] Specifically, the fixing seat 16 is fixed inside the air outlet 14 through the connecting plate 15 , and the air flow can enter the air extraction pipe 11 through the space between the connecting plate 15 and the fixing seat 16 in the air outlet 14 .

[0033] A rotating shaft 22 is provided at the other end of the fan blade seat 2, and an exhaust wheel 23 is provided at the other end of the rotating shaft 22. A rotating shaft 22 is also provided at the other end of the exhaust wheel 23. The other end of the rotating shaft 22 passes through the fixed seat 16, and a bearing 24 is provided at the connection between the fixed seat 16 and the rotating shaft 22. The other end of the rotating shaft 22 is flush with the inner wall of the experimental machine case 1, and a drainage cone 18 is provided at the other end of the rotating shaft 22.

[0034] Specifically, the electric control box 12 is used to control the exhaust wheel 23 to rotate inside the exhaust pipe 11. The rotation of the exhaust wheel 23 drives the rotating shafts 22 at both ends to rotate, so that the rotating shaft 22 at one end rotates inside the fixed seat 16, and at the same time drives the drainage cone 18 to rotate synchronously. The drainage cone 18 can rotate independently of the fixed seat 16 through the bearing 24. When the drainage cone 18 rotates, it is convenient to introduce the hot air flow of the experimental machine case 1 into the exhaust pipe 11; the rotating shaft 22 at the other end drives the fan seat 2 and the fan blades 21 to rotate synchronously, and at the same time drives the fan blade disk 51 and the wheel 5 to rotate at one end of the experimental machine case 1; the cross-sectional area of ​​one end of the exhaust wheel 23 connected to the fan blades 21 is larger than the cross-sectional area of ​​the other end, so that when the exhaust wheel 23 rotates, a pressure difference is produced at both ends, which is convenient for extracting the hot air flow in the experimental machine case 1.

[0035] A limiting hole group 53 is provided at the connection between the side of the fan blade seat 2 and the fan blade 21, a mounting hole 54 is provided on the opposite side of the limiting hole group 53, a magnetic block 55 is provided inside the mounting hole 54, and a magnetic plate group 61 is provided on the side where the fan blade 21 is connected to the fan blade seat 2. The size of the magnetic plate group 61 is the same as the size of the limiting hole group 53, and the number and position of the magnetic plate group 61 correspond to the number and position of the limiting hole group 53.

[0036] Specifically, the fan blades 21 cooperate with the limiting hole group 53 on the fan blade seat 2 through the magnetic attraction plate group 61. When the fan blade seat 2 rotates, the fan blades 21 deflect within the range of the limiting hole group 53 under the action of centrifugal force, so that the exhaust pipe 11 is connected to the outside world; through the cooperation of the magnetic attraction plate group 61 and the magnetic block 55, the fan blades 21 are fixed when sealing the exhaust pipe 11.

[0037] A deflection shaft 6 is arranged at the center of the other end of the fan blade 21, and a plurality of deflection holes 52 are arranged on the inner side surface of the fan blade disk 51. The number of the deflection holes 52 is the same as the number of the fan blades 21, and the positions of the deflection holes 52 correspond to the positions of the deflection shaft 6. The diameter of the deflection holes 52 is the same as the diameter of the deflection shaft 6.

[0038] Specifically, through the cooperation between the deflection shaft 6 and the deflection hole 52, the fan blade 21 is more stable when deflected.

[0039] The air inlet 13 is in the shape of a truncated cone, and the small round end of the air inlet 13 is located on the inner side of the experimental machine case 1; a through hole 31 is arranged inside the air inlet box 3, and the size of the through hole 31 is the same as the size of the small round end of the air inlet 13; limiting grooves 33 are arranged at the bottom and top of the air inlet box 3, and fixed magnetic plates 34 are symmetrically arranged at both ends of the limiting grooves 33; a baffle 4 is arranged inside the through hole 31, and the size of the baffle 4 is the same as that of the through hole 31; a rotating rod 41 is arranged inside the baffle 4, and the two ends of the rotating rod 41 are flush with the bottom and top of the air inlet box 3, and a plurality of rotating magnetic plates 42 are evenly arranged at both ends of the baffle 4 inside the limiting grooves 33.

[0040] Specifically, the truncated cone-shaped air inlet 13 allows the air to enter the experimental machine housing 1 more quickly through the air inlet 13; the air passing through the air inlet 13 pushes the baffle plate 4 to deflect inside the through hole 31, and the deflection of the baffle plate 4 drives the rotating rod 41 to rotate synchronously; the deflection of the rotating rod 41 drives the rotating magnetic plate 42 to rotate, and the angle between two adjacent rotating magnetic plates 42 is 90°. The cover plate 32 limits the rotation of the rotating magnetic plate 42. When the baffle plate 4 is in contact with the through hole 31, the rotating magnetic plate 42 and the fixed magnetic plate 34 are in contact with the opposite side. When the temperature inside the experimental machine housing 1 increases, a relatively large temperature is generated inside and outside the experimental machine housing 1. When the pressure difference is small, the rotating magnetic plate 42 and the fixed magnetic plate 34 will not separate. When the gas inside the experimental machine case 1 is pumped out, a large pressure difference occurs inside and outside the experimental machine case 1, and then the rotating magnetic plate 42 and the fixed magnetic plate 34 can be separated. When the rotating rod 41 is deflected, the rotating magnetic plate 42 and the fixed magnetic plate 34 move on the same side, so that the repulsive force between the rotating magnetic plate 42 and the fixed magnetic plate 34 is balanced with the thrust of the air on the baffle 4. When the experimental machine is not working, the repulsive force between the rotating magnetic plate 42 and the fixed magnetic plate 34 on the same side is greater than the thrust of the air on the baffle 4, so the rotating magnetic plate 42 and the fixed magnetic plate 34 are pushed to fit and fix on the opposite side.

[0041] A cover plate 32 is disposed at the top end of the rotating magnetic plate 42 , and the other end of the cover plate 32 is flush with the two ends of the baffle 4 .

[0042] Specifically, the limiting groove 33 is sealed by the cover plate 32 and rotates along with the rotating magnetic plate 42 .

[0043] During use, the heat generated inside the experimental machine case 1 enters the exhaust pipe 11, and the electrical control box 12 controls the exhaust wheel 23 to rotate inside the exhaust pipe 11, while driving the fan blade seat 2 to rotate, so that multiple fan blades 21 are deflected on the fan blade seat 2, and the exhaust pipe 11 is connected to the outside world. When rotating, the exhaust wheel 23 draws out the hot air inside the experimental machine case 1 and discharges it from the exhaust pipe 11; after the hot air flow in the experimental machine case 1 is drawn out, the internal and external air pressure difference of the experimental machine case 1 increases, and the air outside the experimental machine case 1 enters the experimental machine case 1 from the air inlet 13 through the air inlet box 3, thereby reducing the overall temperature inside the experimental machine case 1.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
