[0002] The power electrical automation control cabinet is mainly used for the automated operation and control of mechanical equipment. There are many cables and electrical components inside it. Especially with the development of the times, human society has entered the era of electrical automation. High-end, precision, and high-power electrical components are widely used, such as: PLC modules, inverters, transformers, industrial computers, relays, precision circuit breakers, thermal stages, etc.; these electrical components will generate a lot of heat during the power-on process, which will accumulate and cause the temperature in the control cabinet to be too high, thereby affecting the performance of the electrical components and even causing damage to some electrical components, resulting in a series of consequences such as failure of the power electrical automation control cabinet and equipment shutdown.

[0003] Existing control cabinets generally have cooling fans installed at fixed positions inside the cabinet. The coverage area of ​​the cooling fans is generally limited and small, which makes it difficult to dissipate heat for some components. Therefore, corresponding improvements are made to address this problem. Summary of the invention

[0004] Based on the technical problems existing in the prior art, the present invention proposes an electric automation control cabinet.

[0005] An electrical automation control cabinet proposed in the present invention comprises a cabinet body, characterized in that a cabinet door is rotatably connected to the front end of the cabinet body, a plurality of air outlets distributed up and down are provided on the cabinet door, a cover page is arranged in the air outlet, a U-shaped door frame is fixed to the back of the cabinet door, a pair of vertical one-way screws are rotatably connected to the door frame, a cross plate capable of moving up and down along the door frame is commonly threadedly connected to the two one-way screws, a heat dissipation fan is elastically connected to the cross plate, a driving rotation component is arranged between the two one-way screws, the driving rotation component is used to drive the one-way screw to rotate, and when the temperature near a certain component inside the control cabinet is too high, the driving rotation component drives the one-way screw to rotate. The one-way screw rotates, and under the action of the one-way screw, the cross plate is driven to move upward or downward. When the one-way screw lifts the cross plate and the cooling fan to the corresponding air outlet, the cooling fan pushes the cover open through the lifting structure, and then the cooling fan will perform targeted heat dissipation on the components at that location. Moreover, since the cooling fan and the cross plate are elastically connected, the cooling fan will rely on the elasticity to vibrate in the vertical direction when working, and then the cover will be driven to reciprocate through the lifting structure, thereby accelerating the air flow inside the control cabinet. On the one hand, it can blow away the dust on the components and take it out, and on the other hand, it can enhance the heat dissipation effect.

[0014] Compared with the prior art, the present invention provides an electrical automation control cabinet, which has the following beneficial effects: 1. An electrical automation control cabinet is provided with a movable heat dissipation fan. When the temperature near a component inside the control cabinet is too high, the one-way screw is driven to rotate by the driving assembly. Under the action of the one-way screw, the cross plate is driven to move upward or downward. When the one-way screw lifts the cross plate and the heat dissipation fan to the corresponding air outlet, the heat dissipation fan pushes the cover page through the lifting structure, and then the heat dissipation fan will perform targeted heat dissipation on the components at that location. Moreover, since the heat dissipation fan and the cross plate are elastically connected, the heat dissipation fan will vibrate in the vertical direction relying on the elasticity when working, and then the cover page will be driven to reciprocate through the lifting structure, thereby accelerating the air flow inside the control cabinet.

[0018] 5. An electrical automation control cabinet is provided with a movable mesh plate. When the one-way screw rotates, it synchronously drives the first bevel gear to rotate, and then engages with another first bevel gear to drive the reciprocating screw to rotate. Under the action of the reciprocating screw, the bottom plate and the mesh plate move back and forth in the horizontal direction.
