Description

Technical Field

[0001] The present application relates to the technical field of control cabinets, and more specifically, to a control cabinet for environmental protection equipment. Background Art

[0002] Environmental protection equipment refers to mechanical products, structures and systems manufactured and built by production units or construction installation units for controlling environmental pollution and improving environmental quality. Environmental protection equipment is usually equipped with a control cabinet. The control cabinet is a switchgear, measuring instrument, protective electrical equipment and auxiliary equipment assembled in a closed or semi-closed metal cabinet or on a screen according to the electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, facilitate maintenance, and not endanger the safety of people and surrounding equipment.

[0003] Chinese Patent Publication No.: (CN218549245U) discloses a control cabinet for environmental protection equipment, including a control cabinet, a cabinet door is arranged at the front end of the control cabinet, a control board is arranged at one end of the cabinet door, a signal board is arranged at one side of the control board, a relay row is arranged on the upper side of the signal board, a thyristor is arranged on one side of the relay row, a circuit breaker is arranged on the other side of the thyristor, and a power terminal is arranged on the lower side of the control board.

[0004] There are still some shortcomings in the above-mentioned related technologies. For example, when the control cabinet is used in a humid environment, the air is generally drawn by a fan to circulate in the cabinet for cooling and dehumidification. The humid air from the outside can easily make the circuits moist and even reduce the service life of electrical components. The dehumidification and drying effect is not good enough. Therefore, in order to solve such problems, we propose a control cabinet for environmental protection equipment. Utility Model Content

[0005] In order to solve the above problems, the present application provides a control cabinet for environmental protection equipment, which adopts the following technical solutions:

[0006] A control cabinet for environmental protection equipment comprises a cabinet body, a plurality of bearing plates for installing electrical components are fixedly installed between the left and right sides of the cabinet body, an air inlet box is penetrated and fixedly installed on the bottom end of the cabinet body, the bottom end of the air inlet box is open, a square tube is penetrated and fixedly installed on the top end of the air inlet box, a ventilation plate for placing desiccant particles is fixedly installed on the inner wall of the air inlet box, an open port is provided on one side of the air inlet box, a door panel is rotatably installed on the open port of the air inlet box, a warm air blowing component is provided in the square tube, a support box is penetrated and fixedly installed on the top end of the cabinet body, the bottom end of the support box is open, the top end of the support box is provided with an open port, a filter is fixedly installed on the open port of the support box, a horizontal plate is fixedly installed between the left and right inner walls of the support box, the horizontal plate penetrates and fixedly installed with a temperature and humidity sensor, and an alarm speaker is fixedly installed on the top end of the horizontal plate.

[0007] Preferably, a plurality of supporting feet distributed in an array are fixedly mounted on the bottom end of the cabinet, and the cross-section of the supporting feet is an inverted T-shaped arrangement.

[0008] Preferably, a plurality of ventilation grooves distributed in an array are provided on the top of the supporting plate.

[0009] Preferably, a plurality of air holes distributed in an array are arranged on the top of the ventilation plate, and the diameter of the air holes of the ventilation plate is smaller than that between the desiccant particles.

[0010] Preferably, the warm air blowing assembly comprises a fan, and the fan is fixedly mounted on the inner wall of the square tube. An electric heater is fixedly mounted on the inner wall of the square tube, and the electric heater is located above the fan.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] By installing the cabinet, the temperature and humidity sensors monitor the temperature and humidity inside the cabinet. When the temperature exceeds the preset value, the warm air blowing component draws the air outside the cabinet into the cabinet through the air inlet box and the ventilation plate. The desiccant particles in the air inlet box dry the air, and the air is discharged from the filter net with the heat in the cabinet. When the humidity is low, the warm air blowing component dehumidifies the air in the cabinet, which improves the dehumidification and drying effect and extends the service life of electrical components.
