Detailed ways

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-3, an electrical cabinet that is easy to dissipate heat includes a cabinet body 1 and a cleaning structure. Two symmetrically arranged heat dissipation nets 15 are fixedly connected to the inside of the cabinet body 1 by screws. A heat dissipation device 20 is installed inside the cabinet body 1. A door panel 21 is movably hinged on one side of the cabinet body 1. A mounting frame 5 is fixedly connected to the top of the cabinet body 1 by screws. A motor 6 is installed inside the mounting frame 5. The output end of the motor 6 is fixedly connected to a coaxially arranged reciprocating screw 7 through a coupling. The cleaning structure includes a support rod 14, which is fixedly arranged inside the cabinet body 1. A sleeve 8 is threadedly sleeved on the outer circumference of the reciprocating screw 7. A gear 9 is movably sleeved on the outer circumference of the sleeve 8. A rack 10 is fixedly connected to the inside of the cabinet body 1 by screws. The gear 9 and the rack 10 are meshingly connected, and a movable block 13 is movably sleeved on the outer peripheral surface of the support rod 14. A rotating block 12 is rotatably installed on one side of the movable block 13. A brush 11 is fixedly arranged on one side of the gear 9 and the rotating block 12. The bottom of the cabinet 1 is fixedly connected with four symmetrically arranged column feet 2 by screws, and the bottom of the column foot 2 is fixedly connected with a fixed block 3 by screws. Through the arrangement of structures such as the motor 6 and the reciprocating screw rod 7, when it is necessary to clean the dust on the heat dissipation net 15, the motor 6 is started, and the motor 6 drives the gear 9 to move, thereby driving the brush 11 to move up and down. Since the gear 9 and the rack 10 are meshingly connected, the gear 9 drives the brush 11 to realize self-rotation, thereby improving the cleaning effect and solving the problem of poor heat dissipation effect.

Please refer to Figure 2. A warning sign 19 and a handle 18 are fixedly connected to one side of the door panel 21 by screws, a rubber pad 4 is fixedly set on the bottom of the fixing block 3, and two symmetrically arranged columns 16 are fixedly connected to the top of the cabinet 1 by screws. One end of the two columns 16 is commonly fixedly connected to a canopy 17 by screws. Through the arrangement of structures such as the canopy 17 and the rubber pad 4, the rubber pad 4 can enhance the friction between the device and the ground and improve the stability. The canopy 17 can prevent rainwater from entering the interior of the cabinet 1 and enhance the service life of the device. The warning sign 19 serves as a warning and solves the problem of poor practicality.

Please refer to Figures 1 and 3. A rotating groove is opened inside the mounting frame 5, and the reciprocating screw rod 7 is rotatably installed inside the rotating groove. A cavity is opened inside the cabinet 1, and the gear 9 is rotatably installed inside the cavity. A through groove is opened inside the gear 9, and the sleeve 8 is rotatably installed inside the through groove. A straight groove is opened inside the rotating block 12, and the movable block 13 is rotatably installed inside the straight groove.

The specific implementation process of the utility model is as follows: when the device is used for heat dissipation, the fan in the heat dissipation device 20 is started. Under the action of the fan, the air in the cabinet 1 is discharged to the outside of the cabinet 1 through the right heat dissipation net 15, so that the temperature of the cabinet 1 is gradually reduced under the drive of the airflow. The heat dissipation net 15 also includes a dust filter. The dust filter prevents dust from entering the cabinet 1 and affecting the electrical components. When dust accumulation causes the heat dissipation efficiency of the heat dissipation net 15 to be low, the motor 6 is started, the motor 6 drives the reciprocating screw rod 7 to rotate, the reciprocating screw rod 7 drives the sleeve 8 to move, and the sleeve 8 drives the gear 9 to move. Since the gear 9 is meshed and connected with the rack 10, and the rack 10 is fixedly arranged inside the cabinet 1, the gear 9 rotates while moving, and the gear 9 drives the brush 11 to rotate. At this time, the brush 11 moves up and down and rotates, which can better clean the heat dissipation net 15. The brush 11 drives the rotating block 12 to rotate, and the rotating block 12 drives the movable block 13 to move. The movable block 13 is movably sleeved on the support rod 14, which can enhance the stability of the brush 11 and solve the problem of poor heat dissipation effect.

In addition, when the device is placed outdoors, the rubber pad 4 fixed at the bottom of the fixing block 3 can increase the friction between the device and the ground to prevent the device from shaking. The canopy 17 set on the top of the cabinet 1 is used to block rain, wind, and falling objects from high altitudes, thereby avoiding damage to items inside the cabinet 1, saving use costs and solving the problem of poor practicality.
