In addition, all embodiments can be used in combination with each other. Embodiment 1

[0027] See also Figures 1 to 7The utility model provides a technical solution: an electrical control cabinet with a fault alarm system, the electrical control cabinet with a fault alarm system comprises: a control cabinet body 1, a cooling fan 4 is arranged on one side of the control cabinet body 1, a temperature sensor 5 is arranged on the upper surface of the control cabinet body 1, and an alarm 6 is arranged on the side of the temperature sensor 5; a fixing frame 8, a slide rail 9 is arranged on the upper surface of the fixing frame 8, a support frame 10 is arranged on the inner surface of the slide rail 9, and a sunshade cloth 15 is arranged between the slide rails 9;

[0028] When the temperature inside the control cabinet body 1 rises to a specific threshold, the temperature sensor 5 activates the alarm 6 through the PLC controller 16 to sound an alarm. The alarm 6 controls the start of the cooling fan 4 while sounding the alarm. The cooling fan 4 introduces the airflow into the control cabinet body 1 through the air intake grille 2 and then leads it out through the air outlet 3, so that the airflow brings out the high-temperature air in the control cabinet body 1 to dissipate the heat of the control cabinet body 1. This working mode can not only quickly warn the operator, but also perform emergency heat dissipation on the control cabinet body 1 to prevent circuit failures caused by high temperature and induced safety hazards. Embodiment 2

[0029] On the basis of the first embodiment, in order to prevent the circuit fault caused by the over-high temperature in the control cabinet body 1, an air intake grille 2 is provided on one side of the control cabinet body 1, an air outlet 3 is provided on the other side of the control cabinet body 1, a heat dissipation fan 4 is fixedly connected to the side of the control cabinet body 1, and the heat dissipation fan 4 is arranged on the outside of the air outlet 3, a temperature sensor 5 and an alarm 6 are fixedly connected to the upper surface of the control cabinet body 1, and footrests 7 are arranged at the four corners of the lower surface of the control cabinet body 1. A PLC controller 16 is arranged in the temperature sensor 5, and the temperature sensor 5 is electrically connected to the alarm 6 through the PLC controller 16, and the alarm 6 is electrically connected to the heat dissipation fan 4;

[0030] When the temperature inside the control cabinet body 1 rises to a specific threshold, the temperature sensor 5 controls the alarm 6 on the upper surface of the control cabinet body 1 to sound an alarm through the PLC controller 16. The alarm 6 sounds an alarm to the operator and controls the start of the cooling fan 4. The cooling fan 4 drives the external air flow into the control cabinet body 1 through the air intake grille 2 to reduce the temperature inside the control cabinet body 1. At the same time, the high-temperature air in the control cabinet body 1 is led out from the air outlet 3, thereby performing emergency heat dissipation on the control cabinet body 1. This working mode can not only quickly warn the operator, but also perform emergency heat dissipation on the control cabinet body 1 to prevent circuit failures and induced safety hazards caused by high temperature. The footrest 7 can raise the control cabinet body 1 to prevent the high temperature of the ground from being transmitted to the control cabinet body 1. Embodiment 3

[0031] On the basis of the second embodiment, in order to prevent the outdoor control cabinet body 1 from continuously heating up due to sunlight, a fixing frame 8 is provided and fixedly connected to both sides of the upper end of the control cabinet body 1, a slide rail 9 is fixedly connected to the upper surface of the fixing frame 8, a support frame 10 is fixedly connected to the inner surface of the slide rail 9, a fixing sleeve rod 11 is provided at the rear end of the inner surface of the slide rail 9, a slide groove 12 is provided on the surface of the slide rail 9, a sliding sleeve rod 13 is provided in the slide groove 12, the sliding sleeve rod 13 is slidably connected to the slide groove 12, counterweight blocks 14 are provided at both ends of the sliding sleeve rod 13, a front end of a sunshade cloth 15 is sleeved on the surface of the sliding sleeve rod 13, and a rear end of the sunshade cloth 15 is sleeved on the surface of the fixed sleeve rod 11;

[0032] When sunlight continues to shine on the control cabinet body 1, the sliding sleeve rod 13 in the slide groove 12 can be slid to the front end of the slide rail 9, so that the sunshade cloth 15 between the fixed sleeve rod 11 and the sliding sleeve rod 13 can be unfolded. The sunshade cloth 15 unfolded on the fixed frame 8 can block the sunlight for the control cabinet body 1 to prevent the temperature in the control cabinet body 1 from constantly rising under the continuous exposure to sunlight. The support frame 10 can ensure that the sunshade cloth 15 is unfolded in an arc shape to provide better shielding for the control cabinet body 1. The counterweight block 14 can make the sliding sleeve rod 13 and the unfolded sunshade cloth 15 more stable.

[0033] Working principle: In actual use, when the temperature inside the control cabinet body 1 rises to a specific threshold, the temperature sensor 5 starts the alarm 6 through the PLC controller 16 to sound an alarm. The alarm 6 controls the start of the cooling fan 4 while sounding the alarm. The cooling fan 4 introduces the airflow into the control cabinet body 1 through the air intake grille 2 and then leads it out through the air outlet 3, so that the airflow brings out the high-temperature air in the control cabinet body 1 to dissipate the heat of the control cabinet body 1. This working mode can not only quickly warn the operator, but also perform emergency heat dissipation on the control cabinet body 1 to prevent circuit failures and induced safety hazards caused by high temperature. This avoids the problem that traditional outdoor electrical control cabinets may be affected by the hot environment during use, causing the internal temperature of the electrical control cabinet to rise and continuously accumulate heat, which may cause circuit failures or safety hazards.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
