DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-4 The utility model is a power distribution cabinet with a protective function, comprising a cabinet body 1, a cooling fan is fixedly arranged inside the cabinet body 1, a ventilation slot 3 is arranged on one side of the cabinet body 1, a fixing frame 4 and a reinforcing frame 9 are fixedly arranged inside the ventilation slot 3, a dustproof plate 11 is arranged on the reinforcing frame 9, a second motor 6 is fixedly arranged on the outer side of the fixing frame 4, a rotating shaft penetrating the fixing frame 4 is arranged at the output end of the second motor 6, a cleaning rod 7 is fixedly arranged at one end of the rotating shaft, cleaning brushes 8 contacting the dustproof plate 11 are arranged at both ends of the cleaning rod 7, a first motor 12 is fixedly arranged inside the cabinet body 1, the first motor 12 is fixed to the rear end of the exhaust fan 13, and a plurality of air outlet holes are arranged on the exhaust fan 13;

[0024] In this structure, after the cooling fan is started, it can provide a wind cooling effect for the electronic parts in the cabinet 1, and can provide a ventilation effect for the cabinet 1 through the ventilation slot 3. In this process, the dustproof plate 11 can provide a dustproof effect for the ventilation slot 3, so that impurities in the air are not easy to enter the interior of the cabinet 1 through the ventilation slot 3, which can make the environment in the cabinet 1 more tidy, and can prevent dust and impurities from adhering to the electronic parts in the cabinet 1, and can ensure the normal heat dissipation of the electronic parts in the cabinet 1;

[0025] When the reinforcement frame 9 is fixed inside the ventilation slot 3, the cleaning brush 8 will contact the dustproof plate 11. Since air will enter the cabinet body 1 from the outside of the cabinet body 1, most of the impurities will adhere to the outside of the dustproof plate 11. Starting the first motor 12 can make air blow at the air outlet. Starting the second motor 6 can make the cleaning rod 7 drive the cleaning brush 8 to rotate. At this time, the cleaning brush 8 can provide a cleaning effect for the dust and impurities on the outside of the dustproof plate 11. With the continuous blowing of the exhaust fan 13, the dust and impurities on the dustproof plate 11 can be easily cleaned, which can improve the cleaning efficiency of the dustproof plate 11.

[0026] In this structure, the first motor 12 is fixed inside the cabinet 1 through a support rod 14, and the bottom end of the support rod 14 is fixed to the inner wall of the cabinet 1 through screws. The screw fixing method has the advantage of easy assembly.

[0027] The lack of a positioning structure between the exhaust fan 13 and the cleaning rod 7 will affect the stability of the exhaust fan 13 when in use. A through hole 16 is provided in the middle portion of the cabinet 1, and a limiting groove 17 is provided in the middle portion of the cleaning rod 7. An insertion rod 15 is provided in the middle portion of the exhaust fan 13, which passes through the through hole 16 and is inserted into the limiting groove 17. One end of the insertion rod 15 is rotatably connected to the cleaning rod 7. Through the cooperation of the insertion rod 15 and the limiting groove 17, a positioning structure can be provided between the exhaust fan 13 and the cleaning rod 7, which can improve the stability of the exhaust fan 13 when in use.

[0028] The reinforcement frame 9 lacks a limiting structure in the ventilation groove 3, which will affect the stability of the reinforcement frame 9 after installation. A groove 5 is provided on the inner wall of the ventilation groove 3, and a limiting block 10 cooperating with the groove 5 is provided on the outer wall of the reinforcement frame 9. Through the cooperation between the limiting block 10 and the groove 5, a limiting structure can be provided for the reinforcement frame 9 in the ventilation groove 3, which can improve the stability of the reinforcement frame 9 after installation.

[0029] Furthermore, the limiting block 10 is fixed inside the groove 5 by screws.

[0030] Furthermore, the first motor 12 and the second motor 6 may both be servo motors.
