[0027] Please see Figures 1-7 This utility model provides a technical solution: a novel high-heat dissipation high and low voltage distribution cabinet, including a base plate 1, a support leg 2 for structural support fixedly connected to the upper surface of the base plate 1, a high and low voltage distribution cabinet 3 for installing electrical components fixedly connected to the upper surface of the support leg 2, a limiting slide rail 4 for limiting the structural trajectory fixedly connected to the bottom wall of the high and low voltage distribution cabinet 3, a drive box 5 for driving the structural installation slidably connected to the inner wall of the limiting slide rail 4, and a useful... The fan blades 6 are used to dissipate heat inside the high and low voltage distribution cabinet 3. A motor 7 with power output is fixedly connected to the inner wall of the high and low voltage distribution cabinet 3. A reciprocating screw 8 is rotatably connected to the inner wall of the limiting slide rail 4 to indirectly drive the fan blades 6 to reciprocate. When the fan blades 6 are used to cool the inside of the high and low voltage distribution cabinet 3, the motor 7 drives the reciprocating screw 8 to rotate. Since the movement trajectory of the drive box 5 is restricted by the limiting slide rail 4, the reciprocating screw 8 will synchronously drive the drive box 5 to move horizontally.

[0028] The output end of the motor 7 is fixedly connected to the reciprocating lead screw 8. The drive box 5 is threaded onto the outer surface of the reciprocating lead screw 8. The outer surface of the reciprocating lead screw 8 is fitted with a first pulley 9 for power transmission. The inner wall of the high and low voltage distribution cabinet 3 is rotatably connected to an outer gear cylinder 10, which is also used for power transmission. The outer surface of the outer gear cylinder 10 is also fitted with a first pulley 9. A first belt 11 is fitted between the two first pulleys 9 to complete the power transmission. When the reciprocating lead screw 8 rotates, it will also drive the outer gear cylinder 10 to rotate with the cooperation of the two first pulleys 9 and the first belt 11. The outer surface of the drive box 5 is provided with a through groove 12 extending into its interior to provide motion space. The inside of the through groove 12 is provided with a fan blade drive assembly. By using the motor 7 in conjunction with the reciprocating lead screw 8 and the fan blade drive assembly, the fan blade 6 can be driven to rotate and perform reciprocating cyclic motion with the help of the first drive source. Compared with the traditional structure, the operating cost of the equipment is reduced.

[0029] The fan blade drive assembly includes a first gear 13 for power transmission, which is rotatably connected to the inner wall of the through slot 12 and meshes with the outer gear cylinder 10. The inner wall of the drive housing 5 is rotatably connected to a first rotating shaft 14 for structural support and power transmission. The outer surface of the first rotating shaft 14 is fitted with a second gear 15 for power transmission and a first gear 16 for accelerating rotation. When the outer gear cylinder 10 rotates, it synchronously drives the first gear 13 to rotate. After the first gear 13 rotates, it synchronously cooperates with the second gear 15 to drive the first rotating shaft 14 to rotate. The second gear 15 meshes with the first gear 13. The inner wall of the drive housing 5 is rotatably connected to a second rotating shaft 17 for structural support and power transmission. The outer surface of the second rotating shaft 17 is fitted with a second gear 18 that cooperates with the first gear 16 to complete acceleration. The second gear 18 meshes with the first gear 16.

[0030] The outer surface of the second rotating shaft 17 is fitted with a second pulley 19, which is also used for power transmission. After the first rotating shaft 14 rotates, it synchronously drives the first speed-changing gear 16 to rotate. After the first speed-changing gear 16 rotates, it drives the second speed-changing gear 18 to rotate. After the second speed-changing gear 18 rotates, it cooperates with the second rotating shaft 17 to drive the second pulley 19 to rotate. The inner wall of the drive box 5 is rotatably connected to a third rotating shaft 20, which is used for structural support and power transmission.

The two second pulleys 19 are connected by a second belt 21, which cooperates with the second pulleys 19 to complete the power transmission. The bottom wall of the drive box 5 is rotatably connected to a drive rod 22, which is used for structural support and power transmission. The outer surface of the drive rod 22 is fitted with a bevel gear 23 for power transmission. The right end of the third rotating shaft 20 is also fixedly connected to a bevel gear 23. The two bevel gears 23 mesh with each other. The upper end of the drive rod 22 rotates through the upper surface of the drive box 5. The upper end of the drive rod 22 is fixedly connected to the rotating shaft of the fan blade 6.

[0031] The third rotating shaft 20 is driven to rotate by the cooperation of two second pulleys 19 and a second belt 21. After the third rotating shaft 20 rotates, it cooperates with two bevel gears 23 to drive the drive rod 22 to rotate. After the drive rod 22 rotates, it drives the fan blade 6 to rotate. The bottom wall of the high and low voltage distribution cabinet 3 is provided with a ventilation slot 24 extending from its lower surface for external air circulation. The inner wall of the ventilation slot 24 is fixedly connected with a dustproof net 25 to prevent dust from entering. The lower surface of the drive box 5 is fixedly connected with a cleaning brush 26 for cleaning the dustproof net 25. The cleaning brush 26 contacts the upper surface of the dustproof net 25. When the drive box 5 moves, it will also drive the cleaning brush 26 to clean the upper surface of the dustproof net 25. The dustproof net 25 inside the ventilation slot 24 can prevent external dust from entering the interior of the high and low voltage distribution cabinet 3 when the fan blade 6 is working. At the same time, the cleaning brush 26 can clean the dustproof net 25 to a certain extent, improving the safety of the electrical components inside the high and low voltage distribution cabinet 3.

[0032] The cleaning brush 26 described in the text is a soft brush, which can allow some of the brush bristles to enter the holes in the dustproof net 25 during the cleaning process, thereby completing the cleaning.

[0033] Working principle: When the fan blades 6 cool the interior of the high and low voltage distribution cabinet 3, the motor 7 drives the reciprocating screw 8 to rotate. Since the movement trajectory of the drive box 5 is restricted by the limit rail 4, the rotation of the reciprocating screw 8 will synchronously drive the drive box 5 to move horizontally. When the reciprocating screw 8 rotates, it will also drive the external gear cylinder 10 to rotate through the cooperation of the two first pulleys 9 and the first belt 11. When the drive box 5 moves, it will drive the internal fan blade drive assembly to move together. Since the external gear cylinder 10 is relatively long, it is always meshed with the first gear 13 when it moves. When the external gear cylinder 10 rotates, it will synchronously drive the first gear 13 to rotate. After the first gear 13 rotates, it will synchronously engage with the second gear. 15 drives the first rotating shaft 14 to rotate. After the first rotating shaft 14 rotates, it synchronously drives the first speed-changing gear 16 to rotate. After the first speed-changing gear 16 rotates, it drives the second speed-changing gear 18 to rotate. After the second speed-changing gear 18 rotates, it cooperates with the second rotating shaft 17 to drive the second pulley 19 to rotate. Through the cooperation of the two second pulleys 19 and the second belt 21, it drives the third rotating shaft 20 to rotate. After the third rotating shaft 20 rotates, it cooperates with the two bevel gears 23 to drive the drive rod 22 to rotate. After the drive rod 22 rotates, it drives the fan blade 6 to rotate, thereby realizing the cyclic movement while the fan blade 6 rotates. At the same time, when the drive box 5 moves, it will also synchronously drive the cleaning brush 26 to clean the upper surface of the dustproof net 25.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
