[0037] Specifically, as shown in Figures 1-3 Alarm device 3 includes mounting plate 31, mounting plate 31 is fixedly connected in control box 1, temperature sensor 32 is fixedly connected to the lower surface of mounting plate 31, by setting temperature sensor 32, temperature sensor 32 can monitor the temperature inside control box 1 in real time;Buzzer alarm 33 and alarm lamp 34 are fixedly connected on mounting plate 31, reset button 35 is installed in mounting plate 31, by setting reset button 35, reset button 35 can control buzzer alarm 33 and alarm lamp 34, so that it resets;Temperature sensor 32 is electrically connected between buzzer alarm 33 and alarm lamp 34, and reset button 35 is electrically connected between buzzer alarm 33 and alarm lamp 34.

[0038] When working, the temperature sensor 32 continuously monitors the temperature inside the control box 1 as the temperature gradually rises. Once the internal temperature reaches the preset threshold, the temperature sensor 32 activates the built-in control unit, triggering the buzzer 33 and the alarm light 34 to sound and flash, thereby notifying the operator to clean and maintain the heat dissipation port 2, ensuring real-time monitoring and effective management of the internal temperature of the control box 1.

[0039] Second embodiment:

[0040] Specifically, as shown in Figures 4-5 The cleaning device 4 includes two housings 41, both of which are mounted on the inner wall of the control box 1. Two sliding plates 42 are slidingly connected inside the housings 41. Two return springs 43 are connected inside the housings 41 and are fixedly connected to the outside of the sliding plates 42. A connecting plate 44 is connected to one side of the sliding plate 42. An arc-shaped plate 45 is connected to one side of the connecting plate 44. A rope 46 is sleeved inside the arc-shaped plate 45. Both ends of the two ropes 46 are connected to the same pull plate 47. A through hole is formed in the arc-shaped plate 45, and the rope 46 is movably connected in the through hole. A cleaning brush for cleaning the heat dissipation port 2 is arranged inside the sliding plate 42. The cleaning brush can clean the heat dissipation port 2 from the inside out, so that the clogged dust can be cleaned.
