Temperature sensors for monitoring the ambient temperature of the cabinet cavity are installed in the four mounting seats. A controller is installed on the top wall of the cabinet cavity. The fan and the temperature sensor are coupled to the controller. The technical principle of the temperature sensor can refer to the pt100 model, and the technical principle of the controller can refer to the S7-200 model.

[0009] As a preferred embodiment, a side cabinet door is connected to the side of the opening of the cabinet inner cavity through a hinge, and a handle is installed on the side cabinet door so that a person can hold the handle and pull the side cabinet door.

[0010] As a preferred embodiment, a protection box is fixedly installed on the top wall of the inner cavity of the cabinet, wherein the protection box cover is arranged on the outside of the controller; so that the protection box can protect the controller to a certain extent.

[0011] As a preferred embodiment, a T-shaped tube is welded at the center of the cabinet top wall, wherein the T-shaped tube is located outside the air outlet; thereby, the hot air discharged from the air outlet can be discharged through the openings on both sides of the T-shaped tube.

[0012] As a preferred implementation scheme, dust-proof nets are installed at the lower position of the air inlet and at the openings on both sides of the T-shaped tube, thereby achieving a certain dust-proof effect.

[0013] As a preferred implementation scheme, a U-shaped bracket is welded to the bottom wall of the cabinet, a servo motor is vertically installed below the bracket, the output shaft of the servo motor is coaxially connected to a mounting plate, and a strip brush that fits the surface of the dust screen in the air inlet is fixedly connected to the mounting plate; a machine cover located on the outside of the servo motor is welded to the bottom wall of the bracket to facilitate protection of the servo motor, and both the fan and the servo motor require power supply from external power facilities.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] The adjustable control cabinet monitors the ambient temperature inside the cabinet in real time through temperature sensors. When the ambient temperature monitored by any temperature sensor reaches a preset threshold (which is unfavorable to electronic components), the temperature sensor transmits an electrical signal to the controller, which drives the two fans to run, allowing outside air to enter the cabinet and discharge heat from the T-shaped exhaust duct. When the ambient temperature drops to a safe value, the two fans stop running. Since the opening and closing of the two fans can be automatically adjusted according to the ambient temperature, the fan running time is reduced, thereby reducing the dust ingress and shortening the maintenance cycle.
