[0026] By adopting the above technical solution, the outer shell 31 can support the protective outer casing 1. When the entire device needs to be moved, the motor 32 drives the lead screw 33 to rotate. The sliding frame 35 is equipped with a nut seat that matches the lead screw 33, so that the sliding frame 35 can move up and down on the surface of the lead screw 33. After the sliding frame 35 pushes out the universal wheel 36 along the slide groove 34, the device can be moved by hand. The mounting component 37 can fix the entire device by fixing the outer shell 31.

[0027] Specifically, the mounting assembly 37 includes a mounting rod 371, a slot 372, a T-shaped rod 373, and a mounting bolt 374.

The ventilation opening 8 accelerates air circulation, achieving a cooling effect. The outer casing 31 supports the protective outer casing 1. When the entire device needs to be moved, the motor 32 drives the lead screw 33 to rotate. The sliding frame 35 is equipped with a nut seat that matches the lead screw 33, allowing the sliding frame 35 to move up and down on the surface of the lead screw 33. After the sliding frame 35 pushes out the caster 36 along the slide groove 34, the device can be moved by hand. One end of the mounting rod 371 can be... The device is connected to the external wall via mounting bolt 374. The depth of the slot 372 is half the width of the mounting rod 371. When moving the device, the mounting rod 371 can be removed from the T-shaped rod 373. When fixing the device, the mounting rod 371 is inserted along the T-shaped rod 373 and then fixed to the external wall. Because the two slots 372 and the T-shaped rod 373 are mirror images, the two T-shaped rods 373 will limit each other to prevent the device from sliding out. The barrier plate 38 prevents animals or small objects from rolling to the bottom of the protective outer box 1. The universal wheel 36 can be pushed out by the motor 32 to drive the lead screw 33 to rotate, increasing the flexibility of the device.

[0034] By adopting the above technical solution, one end of the rotating plate 62 is T-shaped and can be inserted into the grooved plate 63 and fixed. When a lot of dust accumulates on the ventilation opening 8 on the surface of the side plate 7, hold the rotating plate 62 and rotate it around the rotating rod 61 to make the rotating plate 62 separate from the grooved plate 63. After all the rotating plates 62 are separated from the grooved plate 63, the side plate 7 can be removed from the protective outer casing 1 and the ventilation opening 8 can be cleaned. When installing the side plate 7, first use the limiting block 64 to insert into the square groove 65 to fix the side plate 7.

[0035] Specifically, a magnet 66 is fixedly connected to the side of the side plate 7 near the grooved plate 63, and an iron dustproof mesh 67 is provided on the outside of the magnet 66.

[0036] By adopting the above technical solution, the iron dustproof mesh 67 can enhance the dustproof effect by adsorbing onto the inner side of the side plate 7.

[0037] In this embodiment, one end of the rotating plate 62 is T-shaped and can be inserted into and fixed in the grooved plate 63. When a lot of dust accumulates on the ventilation opening 8 on the surface of the side plate 7, hold the rotating plate 62 and rotate it around the rotating rod 61 to disengage the rotating plate 62 from the grooved plate 63. Once all the rotating plates 62 have disengaged from the grooved plate 63, the side plate 7 can be removed from the protective outer casing 1 and the ventilation opening 8 can be cleaned. When installing the side plate 7, first use the limiting block 64 to insert into the square groove 65 to fix the side plate 7. The iron dustproof mesh 67 can enhance the dustproof effect by adsorbing onto the inside of the side plate 7. The side plate 7 can be disassembled and installed at any time by twisting the rotating plate 62, making it convenient to clean the ventilation opening 8.

[0038] The structure and operating principle of the protective outer casing 1, rotating protective door 2, sealed inner casing 4, rotating sealed door 5, ventilation opening 8, power converter body 9, and lighting lamp 10 in this utility model have been disclosed in a pole-mounted DC power converter disclosed in Chinese patent application number CN202420103043.1.

[0039] The working principle and usage process of this utility model: When using this utility model, the motor 32 is connected to an external power source. Both the protective outer casing 1 and the sealed inner casing 4 provide protection for the power converter body 9. The ventilation port 8 accelerates air circulation and achieves a cooling effect. The outer casing 31 can support the protective outer casing 1. When the entire device needs to be moved, the motor 32 drives the lead screw 33 to rotate. The sliding frame 35 is equipped with a nut seat that matches the lead screw 33, allowing the sliding frame 35 to move up and down on the surface of the lead screw 33. After the sliding frame 35 pushes out the universal wheel 36 along the slide groove 34, the device can be moved by hand. One end of the mounting rod 371 can be connected to the external wall through the mounting bolt 374. The depth of the slot 372 is half the width of the mounting rod 371. When moving the device, the mounting rod 371 can be pulled off the T-shaped rod 373. When fixing the device, the mounting rod 371 is inserted along the T-shaped rod 373 and then fixed to the external wall. The two slots 372 and the T-shaped rod 373 are mirror images of each other. The two T-shaped rods 373 will limit each other to prevent the device from sliding out. The barrier plate 38 prevents animals or small objects from rolling to the bottom of the protective outer casing 1. The motor 32 drives the lead screw 33 to rotate, which can extend the caster wheel 36 to move the device and increase its flexibility. One end of the rotating plate 62 is T-shaped and can be inserted into the slotted plate 63 and fixed in place. When a lot of dust accumulates in the vents 8 on the surface of the side plate 7, the rotating plate can be held in place. 62 rotates around the rotating rod 61, allowing the rotating plate 62 to disengage from the grooved plate 63. Once all rotating plates 62 have disengaged from the grooved plate 63, the side plate 7 can be removed from the protective outer casing 1 to clean the ventilation opening 8. When installing the side plate 7, first insert the limiting block 64 into the square groove 65 to fix the side plate 7. The iron dustproof mesh 67 can enhance the dustproof effect by adsorbing onto the inside of the side plate 7. The side plate 7 can be disassembled and installed at any time by twisting the rotating plate 62, making it convenient to clean the ventilation opening 8.
