DETAILED DESCRIPTION

[0019] The application will be further described in detail below with reference to the drawings.

[0020] In order to more clearly understand the technical solutions shown in the embodiments of the application, first, the working principle of the existing temperature control device for alternating current experiment is introduced.

[0021] In the existing alternating current experiment process, components are closed, and the heat generated is measured, and the change of the current passing through is measured by the change of the temperature. In the existing detection equipment, the control temperature structure is a closed structure. When a new measuring device needs to be replaced or connected, the door plate needs to be opened manually, and then connected, which causes the operation process to be complicated and affects the measurement efficiency. Therefore, the existing detection equipment needs to be improved to improve the convenience of temperature control.

[0022] Please refer to Figures 1 to 3 The temperature control device for alternating current experiment disclosed in the embodiment of the application comprises a connecting support plate 1, a connecting cover 2, a test module body 3, a slide 4, a sliding seat 5, a closing cover 6, a heating module 7, a sealing gasket A 8, a sealing gasket B 9, an exhaust pipe 10, a one-way valve B 11, an exhaust fan 12, an air inlet hole 13, an air inlet pipe 14, a one-way valve A 15, a connecting block 16, a lead screw 17, a servo motor 18, and a temperature sensor 19. One end of the connecting support plate 1 is bent upward to form an L shape. The connecting cover 2 is fixedly connected to the inner side surface of the bent part of the connecting support plate 1. The upper end and the right side of the connecting cover 2 are open. The test module body 3 is arranged in the connecting cover 2. The slide 4 is symmetrically arranged on the upper surface of the horizontal part of the connecting support plate 1. The sliding seat 5 is slidably connected to the slide 4. The closing cover 6 is fixedly connected to the upper end of the sliding seat 5. The left side and the lower side of the closing cover 6 are open. The closing cover 6 is connected to the connecting cover 2. The heating module 7 is fixedly connected in the closing cover 6. The edge of the connecting cover 2 is connected to the sealing gasket A 8. The sealing gasket A 8 is fixedly connected to the surface of the inside of the closing cover 6 corresponding to the connecting cover 2. The sealing gasket B 9 is fixedly connected to the surface of the inside of the bent part of the connecting support plate 1 corresponding to the closing cover 6. The edge of the closing cover 6 is connected to the sealing gasket B 9. The exhaust pipe 10 is arranged at the upper end of the closing cover 6. The one-way valve B 11 is arranged in the middle part of the exhaust pipe 10. The exhaust fan 12 is connected to the top of the exhaust pipe 10. The air inlet hole 13 is arranged at the middle position of the lower end of the connecting cover 2. The air inlet pipe 14 is fixedly connected to the connecting cover 2 corresponding to the lower end of the air inlet hole 13. The one-way valve A 15 is arranged on the air inlet pipe 14. The connecting block 16 is fixedly connected to the upper surface away from the bent end of the connecting support plate 1. One end of the lead screw 17 is rotatably connected to the connecting block 16. The other end of the lead screw 17 is rotatably connected to the surface of the bent part of the corresponding connecting support plate 1. The middle part of the sliding seat 5 is threadedly connected to the lead screw 17. The servo motor 18 is fixedly connected to the surface of the connecting support plate 1 corresponding to the right side of the connecting block 16. The output shaft of the servo motor 18 is fixedly connected to the end of the lead screw 17. The temperature sensor 19 is equidistantly fixedly connected to the inner wall of the connecting cover 2.

[0023] Specifically, the connecting support plate 1 is arranged to provide a fixed platform for connecting the tested electrical appliances or switches and other components in the test module body 3 of the connecting cover 2. The test module body 3 can quickly connect common switches, power distribution components and the like. The driving of the servo motor 18 enables the screw rod 17 on the connecting block 16 to rotate, thereby driving the sliding seat 5 to move. The sliding seat 5 enables the closure cover 6 to move close to the connecting cover 2, and the openings of the two are matched with each other to achieve the effect of closure, that is, the connecting cover 2 and the closure cover 6 form a chamber. The sealing gasket A 8 and the sealing gasket B 9 can seal the edges between the two, and the material is elastic fire-resistant material. When the temperature sensor 19 is used, the temperature change trend during internal detection can be obtained. When the temperature exceeds a certain range, the exhaust fan 12 at the upper end of the exhaust pipe 10 can extract the hot air at the upper end of the inside, and then the outside air enters from the air inlet hole 13 at the lower end to reduce the internal temperature. The one-way valve A 15 enables the gas to enter the connecting cover 2 only from the lower end through the air inlet pipe 14. The one-way valve B 11 enables the gas to move upward only from the lower end of the exhaust pipe 10. The opening and closing of the two need a certain suction pressure generated by the exhaust fan 12 to open. When the temperature is low, the internal temperature can be raised by the heating module 7. This overheating state can test the performance change of the circuit under some extreme conditions to meet the measurement range of some common measurements.

[0024] Further, the distance between the connecting cover 2 and the closure cover 6 can be changed by the screw rod 17 to have a certain small gap or a larger gap, so that the internal heat can be freely dissipated to provide another use method. This process does not need the exhaust fan 12 to perform the air extraction operation, and the flexibility is better.

[0028] Specifically, the arrangement of the support pad 21 can lift the connecting support plate 1 to avoid contact with the lower end of the desktop and other supports to improve safety.

[0029] Please refer to Figure 1As another specific embodiment provided by the application, the heat insulation plate 22 is arranged in the gap between the connecting cover 2 and the connecting support plate 1.

[0030] Specifically, the arrangement of the heat insulation plate 22 can avoid heat transfer to the connecting support plate 1, so that the temperature inside the connecting cover 2 is better preserved, and the heat insulation plate 22 can be connected to the inner wall of the connecting cover 2 and the closed cover 6 as needed, and can be matched with a reflective structure, so that the internal heat is more uniform.

[0031] Please refer to Figure 1 As another specific embodiment provided by the application, the scale line 23 is equidistantly arranged on the upper surface of the connecting support plate 1 near the bent side.

[0032] Specifically, the arrangement of the scale line 23 can observe the position when the gap between the closed cover 6 and the connecting cover 2 is adjusted to the heat dissipation state, improving the convenience in use and meeting the needs of actual scenes.

[0033] Please refer to Figure 1 As another specific embodiment provided by the application, the mounting hole 24 is arranged in the respective end of the support pad 21.

[0034] Specifically, the arrangement of the mounting hole 24 facilitates the connection of the support pad 21, so that it is firmly installed on the ground or other supporting objects, ensuring the stable performance of the experiment detection.

[0035] Please refer to Figure 3 As another specific embodiment provided by the application, the control module 25 is fixedly connected to the outer surface of the bent position of the connecting support plate 1, the input end of the control module 25 is electrically connected to the output end of the external power supply, the output end of the control module 25 is electrically connected to the input end of the test module body 3, the heating module 7, the exhaust fan 12 and the servo motor 18, and the output end of the temperature sensor 19 is electrically connected to the signal input end of the control module 25.

[0036] Specifically, the core component of the control module 25 adopts a single-chip microcomputer module, and a computer and other measurement display recording components can record the values of current changes and the like, and can control the servo motor 18 or the exhaust fan 12 according to the values of the temperature sensor 19, thereby realizing an automatic control process and an automatic heating control process.
