DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-3 As shown, a low-voltage complete switch cabinet includes a cabinet body 1, hinges 2 are fixedly connected on both sides of the cabinet body 1, and a switch door 3 is fixedly connected to the other end of the hinge 2. The switch door 3 can be rotated freely through the hinge 2, and the switch door 3 is rotatably connected to the inside of the cabinet body 1 through the hinge 2. At the same time, handles 4 are fixedly connected to the outside of the switch door 3. The switch doors 3 are arranged on both sides of the cabinet body 1, which is convenient for repairing internal components. At the same time, a pillar 7 is fixedly connected to the top of the cabinet body 1, and a baffle 8 is fixedly connected to the top of the pillar 7. The baffle 8 plays a role in blocking falling objects. Two pairs of fixed rods 22 are arranged inside the cabinet body 1. At the same time, connecting plates 10 are fixedly connected to the outside of the fixing rods 22 on both sides, and an electrical component 11 is fixedly connected to the outer wall of the connecting plate 10. The connecting plate 10 plays a role in installing the electrical component 11. A plurality of wiring boards 12 are fixedly connected to the outside of the fixing rods 22. A plurality of wiring holes 13 are opened inside the wiring board 12, and the wiring holes 13 correspond to the electrical components 11. The wiring holes 13 play a role in neat wiring, which is convenient for accelerating the progress of later maintenance.

[0021] like Figure 4 As shown, a heat dissipation mechanism is fixedly connected to one side of the cabinet 1, and the heat dissipation mechanism includes a motor 17 and a fan blade 18. A dustproof net 5 is arranged on the outside of one side of the cabinet 1, and the dustproof net 5 is fixedly connected to one side of the cabinet 1 by multiple screws 6. A plurality of heat dissipation holes 9 are opened on the other side of the cabinet 1. A motor 14 is fixedly connected to the inside of the cabinet 1, and a threaded rod 15 is fixedly connected to the output end of the motor 14, and the other end of the threaded rod 15 is rotatably connected to the inside of the cabinet 1. A connecting block 16 is threadedly connected to the outer wall of the threaded rod 15, and the motor 17 is fixedly connected to the side wall of the connecting block 16, and the fan blade 18 is fixedly connected to the output end of the motor 17, and an outer frame 19 is arranged on the outside of the fan blade 18, and the fan blade 18 is rotatably connected to the inside of the outer frame 19, the motor 17 is fixedly connected to the outer frame 19, and the fan blade 18 is slidably connected to the inside of the cabinet 1, and a slider 20 is fixedly connected to one side of the outer frame 19, and a slide bar 21 is slidably connected to the inside of the slider 20, and the slide bar 21 is fixedly connected to the inside of the cabinet 1.

[0022] By starting the motor 14, the motor 14 drives the threaded rod 15 to rotate, thereby causing the connecting block 16 to move up and down. The movement of the connecting block 16 causes the motor 17 and the outer frame 19 to move up and down. After starting the motor 17, the fan blades 18 rotate under its action and begin to dissipate the heat inside the cabinet 1 through the heat dissipation holes 9 to achieve comprehensive heat dissipation. When moving, the outer frame 19 is limited by the slide bar 21 through the slider 20 to prevent deviation. When rotating, the fan blades 18 are prevented from dust entering through the dustproof net 5 to ensure normal use. The coordination between these components significantly improves the overall heat dissipation efficiency.

[0023] It should be noted that in actual use, the low-voltage switch cabinet is a device used for power system control and protection, usually used in low-voltage electrical distribution systems. First, the cabinet body 1 is designed as a double-door structure. By installing hinges 2 on both sides of the cabinet body 1 and installing switch doors 3 on the hinges 2, the switch doors 3 are opened, and the electrical components 11 are installed on the connecting plate 10 on the fixed rod 22. By passing the line of the electrical components 11 through the wiring hole 13 on the wiring board 12, the wiring of the complex lines is conveniently arranged through the wiring hole 13. After the installation is completed, by starting the motor 14, the threaded rod 15 is driven by the motor 14. The rotation of the threaded rod 15 will drive the connecting block 16 to move up and down, and will drive the motor 17 and the outer frame 19 to move up and down. At this time, the motor 17 is started, and the fan blades 18 will be driven to rotate under the action of the motor 17, and the heat inside the cabinet 1 will begin to be blown out through the heat dissipation holes 9, so as to achieve the effect of comprehensive heat dissipation. At the same time, the outer frame 19 is limited to the outside of the slide bar 21 by the slider 20 when moving to prevent displacement during movement. At the same time, the fan blades 18 will be dustproof through the dustproof net 5 when rotating to prevent dust from entering and affecting normal use. Through the cooperation between them, the heat dissipation efficiency is greatly improved.
