Furthermore, by installing rectangular reflux cooling pipes inside the cabinet and forming a closed reflux space through the connecting cylinder, and by installing [something] inside the rectangular reflux cooling pipes... The water conducts heat, quickly carrying some of the heat generated inside the cabinet to the bottom of the cabinet. The second and first oscillating cooling plates then oscillate to rapidly dissipate heat from the two cooling plates mounted on the rectangular return cooling pipe. This process cools the water inside the rectangular return cooling pipe, or, during the circulation period, the water is replaced via a water exchange valve. The water circulates and conducts heat through the rectangular return cooling pipe, quickly carrying away the heat generated inside the cabinet. This targeted and efficient heat dissipation effectively reduces the internal temperature of the training distribution cabinet, thereby extending its safe service life. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] like Figure 1-10As shown, this utility model provides a technical solution: a high-safety training power distribution cabinet, including a cabinet body 1. A mounting circuit board 2 is fixedly installed on the inner wall of the cabinet body 1. Multiple components are fixedly installed on the surface of the mounting circuit board 2. Rectangular reflux cooling pipes 3 are installed around the inside of the cabinet body 1. Connecting cylinders 6 are rotatably connected between the two ends of the rectangular reflux cooling pipes 3. The connecting cylinders 6 create a circulating reflux space inside the rectangular reflux cooling pipes 3, allowing the water inside to circulate. The interior of the rectangular reflux cooling pipes 3 is connected through the interior of the connecting cylinders 6. The rectangular reflux cooling pipes 3 contain cooling water. The rectangular reflux cooling pipes 3, combined with the water inside, allow the water to circulate within the rectangular reflux cooling pipes. The water inside the return cooling pipe 3 conducts heat, quickly carrying some of the heat generated inside the cabinet 1 to the bottom of the cabinet 1. The second and first cooling plates 11 and 9 then oscillate to rapidly dissipate heat from the two cooling plates 7 mounted on the rectangular return cooling pipe 3, thus cooling the water inside the rectangular return cooling pipe 3. Alternatively, during the circulation period, the water is replaced through the water exchange valve 26, allowing the water to flow and circulate within the rectangular return cooling pipe 3, quickly carrying away the heat generated inside the cabinet 1. This achieves targeted and efficient heat dissipation inside the training distribution cabinet, effectively reducing its internal temperature. A heat dissipation base 4 is fixedly installed at the bottom of the cabinet 1. The heat dissipation base 4 helps to transfer the heat inside the cabinet 1 to the outside more quickly. A bottom mesh support plate 5 is fixedly installed on the inner wall of the cabinet 1. This bottom mesh support plate 5 isolates the heat dissipation base 4 from the cabinet 1 while ensuring air convection. An outward-opening door 29 is installed on the front of the cabinet 1. Two heat dissipation plates 7 are fixedly fitted onto the lower horizontal pipe of the rectangular return cooling pipe 3. These two heat dissipation plates 7, fitted onto the surface of the lower horizontal pipe of the rectangular return cooling pipe 3, utilize their thermal conductivity, combined with the oscillation of the first and second heat dissipation plates 9 and 11 below, to dissipate heat from the water inside the rectangular return cooling pipe 3. To improve heat dissipation, a shaft connecting rod 8 is rotatably connected to the inner left side of cabinet 1. A first heat dissipation plate 9 is fixedly connected to the left side of shaft connecting rod 8. A central connecting rod 10 is fixedly connected to the left side of the first heat dissipation plate 9. A second heat dissipation plate 11 is fixedly connected to the left side of central connecting rod 10. An actuating gear cylinder 13 is fixedly sleeved on the surface of central connecting rod 10. A linkage gear cylinder 12 is fixedly sleeved on the surface of connecting cylinder 6. A sealed belt 14 is sleeved on the surfaces of linkage gear cylinder 12 and actuating gear cylinder 13. Linkage gear cylinder 12 and actuating gear cylinder 13 are connected by a sealed belt 14. An internal rotating rod 15 is provided inside connecting cylinder 6. A fixing collar 16 is fixedly sleeved in the middle of internal rotating rod 15. Connecting rods 17 are fixedly connected to the top and bottom of fixing collar 16.The other end of the connecting rod 17 is fixedly connected to the inner wall of the connecting cylinder 6. Multiple guide vanes 18 are fixedly sleeved on the surface of the built-in rotating rod 15. Through the linkage gear cylinder 12, the starting gear cylinder 13, the sealed belt 14, and the guide vanes 18, the first and second heat dissipation swing plates 9 and 11 can swing, driving the connecting cylinder 6 to rotate via the transmission connection of the linkage gear cylinder 12 and the starting gear cylinder 13. This, in turn, causes the guide vanes 18 inside the connecting cylinder 6 to rotate, thus causing the water in the rectangular return cooling pipe 3 connected to the inside of the connecting cylinder 6 to rotate, accelerating the uniform heat conduction of the water downwards. A connecting plate 19 is fixedly connected to the left side of the second heat dissipation swing plate 11. An end shaft 20 is fixedly connected, and the other end of the end shaft 20 is rotatably connected to the left side of the inner wall of the cabinet 1. A through-hole is provided in the middle of the connecting plate 19, and a shaft cylinder 21 is inserted through the through-hole in the middle of the connecting plate 19. The surface of the shaft cylinder 21 is rotatably connected to the inner wall of the connecting plate 19. A rocker arm 22 is fixedly installed on the middle surface of the shaft cylinder 21, and a V-shaped plate 23 is rotatably fitted on the surface of the rocker arm 22. A servo motor 24 is fixedly installed on the front of the cabinet 1. A rotating rod 25 is fixedly connected to the output shaft of the servo motor 24. One end of the rotating rod 25 is inserted into the interior of the cabinet 1, and the other end is fixedly connected to the surface of the V-shaped plate 23. Through the arrangement of the connecting plate 19, the shaft cylinder 21, the rocker arm 22, and the V-shaped plate 23, the cabinet 1 achieves the following function: The servo motor 24 drives the rotating rod 25 to rotate, causing the V-shaped plate 23 to swing around the rotating rod 25. Through the hinged linkage of the shaft cylinder 21, rocker arm 22, and V-shaped plate 23, the connecting plate 19 drives the second heat dissipation plate 11 and the first heat dissipation plate 9 to continuously oscillate at the heat dissipation openings below the cabinet 1. This rapidly dissipates the heat accumulated inside the cabinet 1 through the heat dissipation vents on the front and back of the cabinet 1 and the heat dissipation base 4, accelerating the efficiency of heat dissipation from the cabinet 1. The heat dissipation base 4 has heat dissipation vents on both the front and back, and the cabinet 1 has two vents on both the front and back that work in conjunction with the first heat dissipation plate 9 and the second heat dissipation plate 11. The cabinet 1 has two U-shaped limiting slots 27 fixedly installed on its front side. A sealed cable door 28 is inserted into the slot between the two U-shaped limiting slots 27. The sealed cable door 28 allows for the sealing or opening of the heat dissipation vents on the front and back of the heat dissipation base 4 and the cabinet 1. Water exchange valve pipes 26 are fixedly inserted on both sides of the cabinet 1. The other end of the water exchange valve pipe 26 is connected to the surface of the rectangular return cooling pipe 3, and the interior of the water exchange valve pipe 26 is connected to the interior of the rectangular return cooling pipe 3. The water exchange valve pipes 26 on both sides of the cabinet 1 allow for the replacement of the water inside the rectangular return cooling pipe 3.
[0029] In use, the servo motor 24 starts, driving the rotating rod 25 to rotate, causing the V-shaped plate 23 to swing around the rotating rod 25. Through the hinged linkage of the shaft cylinder 21, rocker arm 22, and V-shaped plate 23, the second heat dissipation swing plate 11 and the first heat dissipation swing plate 9 continuously oscillate at the heat dissipation openings below the cabinet 1 via the connecting plate 19. This rapidly dissipates the heat accumulated inside the cabinet 1 through the heat dissipation openings on the front and back of the cabinet 1 and the heat dissipation base 4, accelerating the efficiency of heat dissipation from the cabinet 1. Simultaneously, the water inside the rectangular reflux cooling pipe 3 conducts heat, quickly carrying some of the heat generated inside the cabinet 1 to the bottom of the cabinet 1, where it is dissipated by the oscillating heat dissipation second and first heat dissipation swing plates 11 and 9. The two heat dissipation and cooling plates 7 on the top circulate air to quickly dissipate heat to the outside, allowing the heat generated inside the cabinet 1 to be quickly carried away by the heat conduction circulation of water in the rectangular return cooling pipe 3. The water inside the rectangular return cooling pipe 3 can be replaced at regular intervals. That is, the external water pipe is directly connected to the water replacement valve pipe 26 on one side and the wastewater pipe or collection tank on the other side. Then, the water replacement valve pipes 26 on both sides are opened to replace the originally high temperature water inside the rectangular return cooling pipe 3, and the rectangular return cooling pipe 3 is filled with water to cool it down. The water inside the rectangular return cooling pipe 3 that has been heated is directly replaced, thereby effectively reducing its internal temperature and improving the safe service life of its training distribution cabinet. At the same time, the contents not described in detail in this manual are all existing technologies known to those skilled in the art.
[0030] In summary, this high-safety training power distribution cabinet, driven by a servo motor 24, rotates the rotating rod 25. This, combined with the hinged linkage of the shaft cylinder 21, rocker arm 22, and V-shaped plate 23, causes the second heat dissipation plate 11 and the first heat dissipation plate 9 to continuously oscillate at the heat dissipation openings below the cabinet body 1 via the connecting plate 19. This rapidly dissipates the heat accumulated inside the cabinet body 1 through the heat dissipation openings on the front and back of the cabinet body 1 and the heat dissipation base 4, accelerating the efficiency of heat dissipation from the cabinet body 1 in a short time. Furthermore, the installation of rectangular reflux cooling pipes 3 inside the cabinet body 1, connected by a connecting cylinder 6 to form a closed reflux space, further enhances the efficiency of heat dissipation. The water inside pipe 3 conducts heat, quickly carrying some of the heat generated inside cabinet 1 to the bottom of cabinet 1. The second and first heat dissipation plates 11 and 9, which are oscillating for heat dissipation, rapidly cool the water inside the rectangular return cooling pipe 3. Alternatively, during the circulation period, water is added to the rectangular return cooling pipe 3 via the water exchange valve pipe 26 for cooling. This allows the water to circulate and conduct heat through the rectangular return cooling pipe 3, quickly carrying away the heat generated inside cabinet 1. This targeted and efficient heat dissipation of the training distribution cabinet effectively reduces its internal temperature, thereby improving its safe service life.
