[0008] As an improvement of the above solution, it also includes cabinet doors, and the left and right sides of the front of the cabinet body are rotatably connected with the cabinet doors.
[0009] As an improvement to the above solution, heat dissipation openings are provided at the bottom of the cabinet doors.
[0010] As an improvement of the above solution, a fan is also included, and the upper sides of the left and right parts of the cabinet are both connected to the fans.
[0011] As an improvement to the above solution, handles are provided on the cabinet doors.
[0012] The beneficial effects of the utility model are as follows: the utility model utilizes the principle of expansion of the hollow column due to heat, lifts the fixing frame so that the control plate drives the guide plate to move upward, and the guide plate moves upward to control the blade plate to rotate and open, which can automatically enhance the heat dissipation performance of the cabinet and improve the safety of use when the temperature inside the cabinet is too high.

[0018] 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.
[0019] An electrical control cabinet with a ventilation structure, such as Figure 1-Figure 4 As shown, it includes a cabinet 1, a cabinet door 2, a fan 4, a connecting column 5, a blade 6, a guide plate 7, a control panel 8, a fixing frame 9, a guide frame 10 and an expansion hollow column 11. A plurality of connecting columns 5 are rotatably connected to the left side of the cabinet 1, and blades 6 are connected to the connecting columns 5. Guide plates 7 are connected to the rear sides of the connecting columns 5. Control panels 8 are connected between the guide plates 7, and a plurality of fixing frames 9 are connected to the control panel 8. A plurality of guide frames 10 are connected to the inner side of the left portion of the cabinet 1, and expansion hollow columns 11 are arranged at the lower portion of the guide frames 10. The expansion hollow columns 11 are squeezed and matched with the adjacent fixing frames 9, and the fixing frames 9 are slidably connected with the adjacent guide frames 10. Cabinet doors 2 are rotatably connected to the left and right sides of the front of the cabinet 1, and heat dissipation ports 3 are provided at the lower portion of the cabinet doors 2. Fans 4 are connected to the upper sides of the left and right portions of the cabinet 1.
[0020] When the utility model is in use, the cabinet 1 is placed in the use area, and the cabinet door 2 is opened to install the electrical control equipment or electrical control accessories inside the cabinet 1. The heat generated by the operation of the electrical control equipment or electrical control accessories inside the cabinet 1 is discharged through the cooperation of the heat dissipation port 3 and the fan 4. When the temperature inside the cabinet 1 is too high, the expansion hollow column 11 expands due to the heat and squeezes the fixed frame 9. The fixed frame 9 moves upward to drive the control board 8 to move upward. The control board 8 moves upward and the underground blade 6 rotates and unfolds through the guide plate 7. The rotation and unfolding of the blade 6 increases the heat dissipation performance inside the cabinet 1. When the temperature inside the cabinet 1 returns to normal, the expansion hollow column 11 shrinks automatically due to the gradual decrease in temperature, so that the fixed frame 9 and the control board 8 move downward, and the blade 6 automatically rotates and closes.
[0021] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
