[0026] Please see Figure 1-5 This utility model provides a technical solution:

[0027] A universal adapter box for distribution network automation terminals, such as Figure 1-5 As shown, the distribution terminal box includes a distribution terminal housing 1. Mounting lugs 5 are fixedly connected to all four sides of the outer perimeter of the distribution terminal housing 1. Multiple grooves 3 are opened at the right end of the distribution terminal housing 1, and ventilation mesh 4 for heat dissipation is fixedly connected within the grooves 3. Two circular shells 10 are fixedly connected to the left end of the distribution terminal housing 1, and a fan device 11 is rotatably connected within each of the circular shells 10. Multiple rectangular through slots 9 are opened on the left wall of the distribution terminal housing 1. A cooling device 2 is fixedly connected to the left side of the distribution terminal housing 1. The lower wall of the distribution terminal housing 1... T-shaped blocks 8 are fixedly connected to the left side and the right side of the lower box wall. The main body device 6 is slidably connected to the outer side of the two T-shaped blocks 8. The front end of the distribution terminal box 1 is connected to the box door 7 by a hinge. The grooves 3 are vertically and evenly arranged on the right side box wall of the distribution terminal box 1. The outer edge of the ventilation net 4 is tightly fitted to the inner wall of the groove 3. The internal cavity of the round shell 10 is connected to the internal cavity of the distribution terminal box 1 by a rectangular through groove 9. The blowing direction of the fan equipment 11 is towards the inside of the distribution terminal box 1.

[0028] The above scheme enables the stable installation and fixation of the junction box in the designated position through the mounting lugs 5 on the outer perimeter of the distribution terminal box 1, providing a reliable installation foundation for the overall equipment. When the electronic components inside the box generate heat, the fan device 11 inside the round shell 10 at the left end of the distribution terminal box 1 can send external air into the box through the rectangular through slot 9. At the same time, the hot air inside the box can be discharged through the vertically evenly arranged grooves 3 at the right end and the tightly fitted ventilation mesh 4 inside, forming an efficient air circulation and heat dissipation channel. The T-shaped block 8 on the lower box wall provides stable sliding support for the main device 6, and the front box door 7 can be closed when the equipment is running.

[0029] Please see Figure 1 , Figure 2 and Figure 3 The cooling device 2 includes a fluid tank 21. An injection cap 22 is provided at the upper front of the fluid tank 21. A delivery pipe 26 is fixedly connected to the lower front of the fluid tank 21. A circulating cooling pipe 23 is fixedly connected to the other end of the delivery pipe 26. A discharge pipe 27 is fixedly connected to the other end of the circulating cooling pipe 23. A circulating tank 28 is fixedly connected to the other end of the discharge pipe 27. A circulating pipe 29 is fixedly connected to the left front of the circulating tank 28. Two switching valves 210 are fitted on the outer surface of the circulating pipe 29. The other end of the circulating pipe 29 is fixedly connected to the left end of the fluid tank 21. Multiple fixing clips 24 are snapped onto the outer side of the circulating cooling pipe 23, and the fixing clips 24 are fixedly connected to the left box wall of the distribution terminal box 1 by bolts. A switch valve 25 is sleeved on the outer surface of the conveying pipe 26. The fluid box 21 is fixedly connected to the left side of the upper box wall of the distribution terminal box 1, and the circulation box 28 is fixedly connected to the left side of the lower box wall of the distribution terminal box 1. The fluid box 21 and the circulation box 28 are distributed vertically in correspondence. The circulating cooling pipe 23 is distributed in a serpentine pattern on the inner side of the left box wall of the distribution terminal box 1. The fixing clips 24 are distributed at intervals along the path of the circulating cooling pipe 23.

[0030] With the above solution: Workers can open the injection cap 22 at the front of the fluid tank 21 to add cooling fluid. During use, the switch valve 25 on the delivery pipe 26 is opened, and the cooling fluid flows from the fluid tank 21 through the delivery pipe 26 into the circulating cooling pipe 23, which is serpentinely distributed on the inner side of the left wall of the distribution terminal box 1. The serpentine distribution of the circulating cooling pipe 23 significantly increases the contact area with the air inside the box, allowing for more complete absorption of heat and improved cooling efficiency. The circulating cooling pipe 23 is fixed to the box wall by clamps 24 spaced along its path, ensuring the stability of the installation and preventing damage to the cooling pipe due to equipment vibration. If the device is displaced or damaged, the cooling fluid that has absorbed heat will flow through the discharge pipe 27 into the circulation tank 28, which is distributed vertically and vertically to the fluid tank 21. By opening the two switch valves 210 on the circulation pipe 29, the cooling fluid can be returned to the fluid tank 21 through the circulation pipe 29 for recycling, reducing the consumption of cooling fluid and lowering the operating cost. This cooling device 2, together with the fan equipment 11, forms a dual heat dissipation structure, which can effectively cope with the large amount of heat generated by the electronic components in the box under high load, ensure that the temperature inside the box is maintained within a suitable range, ensure the stable realization of the transfer function of the distribution network automation terminal, avoid component failure due to high temperature, and improve the stability of equipment operation.

[0031] Please see Figure 1 and Figure 5 The main device 6 includes a tray 61. The lower left and lower right sides of the tray 61 are provided with sliding grooves 63. The front middle of the tray 61 is provided with a handle groove 62. The upper front of the tray 61 is fixedly connected to an electronic integrated device 64. Multiple connecting wires 69 are inserted and fixedly connected to the rear end of the electronic integrated device 64. The upper rear of the tray 61 is fixedly connected to a rear plate 65. The upper front and lower front of the rear plate 65 are fixedly connected to a connecting frame 67. Multiple wire holes 68 are provided at the upper end of the connecting frame 67. The tray 61 is slidably connected inside the distribution terminal box 1. The tray 61 moves along the front and rear direction of the distribution terminal box 1 through the sliding engagement of the sliding grooves 63 and the T-shaped block 8. The wire holes 68 are arranged horizontally and evenly on the connecting frame 67. Multiple connecting wires 69 pass through the corresponding wire holes 68 and are connected to the electrical interface inside the distribution terminal box 1.

[0032] Through the above scheme: the tray 61 of the main device 6 can move smoothly in the front and back direction through the sliding grooves 63 on the lower left and right sides and the T-shaped block 8 on the lower wall of the distribution terminal box 1. The staff can easily pull the tray 61 out of the box through the handle groove 62 in the middle of the front end of the tray 61, which facilitates the installation, inspection and maintenance of the electronic integrated equipment 64 at the front of the upper end of the tray 61 without having to go deep into the box, reducing the difficulty of operation and improving the maintenance efficiency. The multiple connecting wires 69 at the rear end of the electronic integrated equipment 64 pass through the corresponding wire holes 68 arranged horizontally and evenly on the connecting frame 67 and connect to the electrical interface in the box. The wire holes 68 play a role in organizing and fixing the connecting wires 69, avoiding the situation where multiple connecting wires 69 are tangled and messy. This not only makes it easier for the staff to quickly identify each line and reduce the time for line inspection and maintenance, but also prevents problems such as poor contact caused by line tangling. The rear plate 65 and the connecting frame 67 provide a reliable support structure for the line.

[0033] It should be noted that this utility model is a universal adapter box for distribution network automation terminals. After the distribution network terminal box 1 is fixedly installed by the mounting lugs 5, the main body 6 inside is slidably connected to the T-shaped block 8 at the bottom of the box through the sliding groove 63 at the lower part of the support plate 61. It can be easily pulled out from the box door 7 for maintenance. During operation, the heat generated by the electronic integrated equipment 64 is dissipated by the cooling device 2 on the left and the fan device 11. Specifically, the cooling medium in the fluid tank 21 flows into the serpentine circulating cooling pipe 23 through the conveying pipe 26. The circulating cooling pipe 23, which is fixed to the box wall by the fixing clamp 24, exchanges heat inside the box. The heat-absorbing medium enters the circulation box 28 through the discharge pipe 27, and can flow back to the fluid box 21 through the circulation pipe 29 under the control of the switch valve 210 to achieve circulation. At the same time, the fan equipment 11 inside the round shell 10 blows air into the box through the rectangular through slot 9, forming air convection with the ventilation net 4 installed in the right groove 3, further enhancing the heat dissipation effect, thereby ensuring the stable operation of the connecting line 69 of the electronic integrated equipment 64 laid through the wire hole 68 on the connecting frame 67.
