Description

Technical Field

[0001] This utility model mainly relates to the field of control cabinet technology, specifically an electrical automation training control cabinet. Background Technology

[0002] The electrical automation training control cabinet is an experimental device specifically designed for teaching and skills training. It is primarily used to simulate the design, installation, and debugging of industrial automation control systems. It integrates core components from the field of electrical control, helping learners master technologies such as PLC programming, sensor applications, and motor control.

[0003] Among them, smoke elimination and cooling of control cabinets is a common technical problem. Electrical automation training control cabinets are used for training simulations in fields such as smoke elimination and cooling equipment. The simulation training of smoke elimination and cooling equipment usually needs to demonstrate airflow organization, heat dissipation principle or fault simulation (such as fan failure leading to overheating). Therefore, training control cabinets may be designed with more air outlets or adjustable air duct structures. Existing cabinets usually use air ducts that flow in the front and back or air ducts that flow in all four directions for heat dissipation. Air ducts that only flow in the front and back have poor heat dissipation effect. However, if air outlets are opened in all four directions, too many air outlets will make it easy for dust to enter the cabinet, causing dust to accumulate too quickly inside the cabinet and requiring frequent cleaning. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. It mainly provides an electrical automation training control cabinet to solve the technical problems mentioned in the background, such as poor heat dissipation in the front and rear ventilation channels of existing control cabinets, air outlets in all four directions (front, back, left, and right), and excessive dust accumulation inside the cabinet.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] An electrical automation training control cabinet includes a cabinet body with a door. Electrical components are installed inside the cabinet body. Multiple sets of air vents for internal airflow are provided on the cabinet body. A first fan, a second fan, and a third fan are installed inside the cabinet body to dissipate heat from the interior of the cabinet body. The first fan, the second fan, and the third fan are longitudinally staggered. A baffle is provided on the cabinet body to block the air vents on the sides of the cabinet body.

[0007] Preferably, the first fan is located on the rear side of the cabinet, and the second and third fans are located on the left and right sides inside the cabinet, respectively. Side panels are provided on the left and right sides of the cabinet.

[0008] Preferably, the air outlet group includes a first air outlet and a second air outlet, the first air outlet is located at the front of the cabinet and inside the door, and the second air outlet is located on the side panel.

[0009] Preferably, a baffle is slidably connected to the side panel, a handle is provided on the baffle, a support plate is hinged to the cabinet body, and a hook for fixing the raised handle is provided on the support plate.

[0010] Preferably, the second fan is located inside the cabinet on one side, and a pulley is provided on the same side inside the cabinet. A tension rope is provided on the baffle on the same side, passing through the pulley and connecting to the second fan bracket. A first telescopic sleeve is provided between the second fan bracket and the cabinet.

[0011] Preferably, the third fan is located inside the cabinet on the side opposite to the second fan. A second telescopic sleeve is provided between the third fan bracket and the cabinet. A docking block is provided on the third fan bracket, and a top block is provided on the baffle on the same side. The top block and the docking block are docked with each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: when the internal temperature of the cabinet is not high, the first air outlet and the first fan form a front-to-back airflow to dissipate heat inside the cabinet. At this time, the second and third fans on both sides can also be activated to blow air on both sides of the electrical components to dissipate heat. When the internal temperature is not too high, closing the two side air outlets can prevent dust from entering the cabinet and reduce the number of times the dust inside the cabinet needs to be cleaned.

[0013] When the internal temperature of the cabinet is high, pull up the side panels on both sides to open the second ventilation openings on both sides. At this time, the second fan will descend and the third fan will rise. The first, second, and third fans are vertically staggered, working in conjunction with the first and second air outlets to achieve efficient heat dissipation inside the cabinet. Because the three sets of fans are staggered, the airflow direction formed by each fan and the air outlet reduces the mutual interference. Opening all the air outlets at this time can improve the heat dissipation effect inside the cabinet.

[0027] Please refer to the appendix carefully. Figures 1-7An electrical automation training control cabinet includes a cabinet body 1, a door 2 on the cabinet body 1, electrical components 5 inside the cabinet body 1, multiple sets of air outlets for internal airflow on the cabinet body 1, a first fan 3, a second fan 12 and a third fan 16 for heat dissipation inside the cabinet body 1, and the first fan 3, the second fan 12 and the third fan 16 are longitudinally staggered from each other, and a baffle 8 is provided on the cabinet body 1 to block the air outlets on the side of the cabinet body 1.

[0028] The specific operating procedure of this utility is as follows: Open door 2. At this time, the air outlet in front of cabinet 1, which is directly opposite the first fan 3, is open. At this time, the first fan 3, the second fan 12, and the third fan 16 are at the same height. Start the first fan 3 to dissipate heat from the electrical components 5 inside cabinet 1. Since the first fan 3 is directly opposite the air outlet, the first fan 3 and the air outlet in front form an air duct to achieve heat dissipation. At this time, the second fan 12 and the third fan 16 can also be turned on. The second fan 12 and the third fan 16 blow air on both sides of the electrical components 5 to achieve heat dissipation. When the heat inside cabinet 1 is too high, open the air outlets on the left and right sides. At the same time, the second fan 12 will descend and the third fan 16 will rise. At this time, the first fan 3, the second fan 12, and the third fan 16 are staggered, and each fan is directly opposite an air outlet. Start the first fan 3, the second fan 12, and the third fan 16. Each fan, together with the air outlet it is facing, will form an air duct to dissipate heat. And because the three sets of fans are staggered, the influence between them will be smaller.

[0029] Please refer to Figures 1-3 The first fan 3 is located on the rear side of the cabinet 1, the second fan 12 and the third fan 16 are located on the left and right sides inside the cabinet 1 respectively, and the left and right sides of the cabinet 1 are provided with side panels 6. The air outlet group includes a first air outlet 4 and a second air outlet 7. The first air outlet 4 is located in front of the cabinet 1 and is located inside the door 2. The second air outlet 7 is opened on the side panel 6.

[0030] The first fan 3, the second fan 12, and the third fan 16 are all equipped with motors that drive the fans. When the second air outlet 7 is closed, the first fan 3, the second fan 12, and the third fan 16 are at the same height. The first fan 3 faces the first air outlet 4, and the second fan 12 and the third fan 16 each face a second air outlet 7. When only the first air outlet 4 is open, the first fan 3 and the first air outlet 4 form an air duct. The second fan 12 and the third fan 16 can be turned on selectively according to the temperature of the electrical component 5. Cooling is achieved by blowing air onto the two sides of the electrical component 5 through the second fan 12 and the third fan 16.

[0031] Please refer to Figures 1-7A baffle 8 is slidably connected to the side panel 6, and a handle 9 is provided on the baffle 8. A support plate 10 is hinged to the cabinet body 1, and a hook 11 is provided on the support plate 10 for fixing the raised handle 9.

[0032] A torsion spring is installed at the hinge of the support plate 10 and the cabinet 1. The support plate 10 can no longer be bent downwards, but can only be pushed upwards. The second air outlet 7 on the side panel 6 is controlled to open or close by the baffle 8. When the second air outlet 7 needs to be opened, pull the handle 9 upwards. The handle 9 drives the baffle 8 to rise and open the second air outlet 7. The handle 9 pushes open the support plate 10 above. After the handle 9 passes the support plate 10, the support plate 10 returns to its original position under the action of the torsion spring. At this time, release the handle 9. The handle 9 descends and inserts into the hook 11. The hook 11 supports the handle 9. At this time, the baffle 8 cannot descend to close the second air outlet 7. When the second air outlet 7 needs to be closed, pull the handle 9 upwards to disengage from the hook 11, and then bend the support plate 10 upwards to make the baffle 8 descend and close the second air outlet 7.

[0033] Please refer to Figure 5 The second fan 12 is located inside the cabinet 1 on one side. A pulley 14 is located inside the cabinet 1 on the same side. A tension rope 13 is provided on the baffle 8 on the same side, passing through the pulley 14 and connected to the bracket of the second fan 12. A first telescopic sleeve 15 is provided between the bracket of the second fan 12 and the cabinet 1.

[0034] The first telescopic sleeve 15 is used to support and limit the second fan 12. The first telescopic sleeve 15 is used to ensure the stability of the second fan 12 during operation and prevent large vibrations during operation. When the baffle 8 on the same side as the second fan 12 rises, the baffle 8 will release the tension rope 13. The tension rope 13 passes through the pulley 14 and lowers the second fan 12. When the baffle 8 rises, the second fan 12 is lowered to the bottom of the cabinet 1.

[0035] Please refer to Figure 6 The third fan 16 is located inside the cabinet 1 on the side opposite to the second fan 12. A second telescopic sleeve 17 is provided between the bracket of the third fan 16 and the cabinet 1. A docking block 19 is provided on the bracket of the third fan 16. A top block 18 is provided on the baffle 8 on the same side. The top block 18 and the docking block 19 are docked with each other.

[0036] The second telescopic sleeve 17 is used to support and limit the third fan 16, limiting the lowest position of the third fan 16 to the middle position inside the cabinet 1, preventing it from descending to the bottom of the cabinet 1. Similarly, the second telescopic sleeve 17 is used to support the stability of the third fan 16 during operation. When the baffle 8 on the same side as the third fan 16 rises, the baffle 8 rises a certain distance, and the top block 18 and the docking block 19 engage with each other. At this time, the baffle 8 continues to rise, pulling the third fan 16 up through the top block 18 and the docking block 19. After the baffle 8 is fixed in place, the third fan 16 is located in the bottom cavity inside the cabinet 1 near the top plate. At this time, the three fans are staggered. There is a certain distance between the second fan 12 and the third fan 16 and the baffle 8, so they do not fit against the baffle 8 to prevent affecting the air blowing effect of the second fan 12 and the third fan 16.

[0037] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
