Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinets, in particular to a ventilation base for an electrical cabinet. Background Art

[0002] Electrical cabinets are made of steel and are used to protect components. They are generally made of hot-rolled and cold-rolled steel. Cold-rolled steel is softer than hot-rolled steel, making it more suitable for cabinet construction. They are widely used in the chemical industry, environmental protection, power systems, metallurgy, industry, nuclear power, fire safety monitoring, transportation, and more. Since the internal electrical components of the electrical cabinet need to work continuously during use, the electrical components will generate heat when working continuously. It is necessary to be able to discharge the heat generated by the electrical components out of the electrical cabinet in time to better ensure the stability of the environment inside the electrical cabinet. The heat generated by the operation of the electrical components will move upward, and the airflow at the bottom of the electrical cabinet will be affected. However, the ventilation holes at the bottom of the traditional electrical cabinet have poor airflow due to their shape design, and for some larger cabinets, the airflow from the side ventilation holes cannot flow to the middle position of the electrical cabinet, which will result in poor heat dissipation. In addition, the base of the electrical cabinet is the part where the lines pass. In order to avoid dust or debris from entering the interior of the electrical cabinet from the base during use, it is necessary to ensure that the cables pass smoothly while also having certain dust-proof properties. Therefore, a ventilation base for the electrical cabinet is needed. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide an electrical cabinet ventilation base to solve the problem of poor performance of the traditional base in the prior art.

The V-shaped bracket can be used to improve the supporting stability of the ventilation support plates, and a ventilation wind screen is arranged in the interval gap of the V-shaped bracket. In this way, a flow difference can be formed with the ventilation support plate on the other side, thereby improving the gas convection effect and accelerating the airflow convection speed inside the electrical cabinet.

In order to prevent the component support plate from affecting the smooth flow of air in the cabinet, ventilation holes are opened on the reinforcement plate to ensure the smooth flow of air in the cabinet.

[0012] In one embodiment of the present invention, a convection fan is further provided on the lower side of the component support plate. At least two groups of convection fans are provided, and the two groups of convection fans blow air in opposite directions.

[0013] To implement the above technical solution, in order to improve the flow stability and smoothness of the airflow in the electrical cabinet, a convection fan is also provided on the lower side of the component support plate, and the blowing direction of the convection fan is set in the opposite direction to ensure the smooth flow of gas in the cabinet, thereby accelerating the airflow speed at the bottom of the cabinet and forming a flowing airflow with the hot air flow in the cabinet.

[0014] In one embodiment of the present invention, brush bases are provided on both sides of the wire hole, a brush seat is provided at the root of the blocking brush, and the brush seat and the brush base are connected by bolts.

[0015] By implementing the above technical solution, the provision of the brush base can facilitate the installation and removal of the brush holder, thereby improving ease of use.

[0016] In one embodiment of the present invention, the blocking brush is made of rubber.

[0017] By implementing the above technical solution, the rubber material can have good flexibility, which facilitates the passage of cables and at the same time tightly wraps the cables.

[0019] To implement the above technical solution, the four sides of the ventilation support plate are fastened to the support plate seat, which can improve the connection stability and convenience between the ventilation support plate and its plate seat. The ventilation surface of the ventilation support plate and the support plate seat are spaced apart to facilitate the circulation of airflow during use.

[0020] In one embodiment of the present invention, a support plate limiting plate is provided on the support plate seat, and the support plate limiting plate is supported between the ventilation surface of the ventilation support plate and the support plate seat.

[0021] To implement the above technical solution, by setting a support plate limit plate, on the one hand, the support plate limit plate can be used to connect the ventilation support plate and the support plate seat, and on the other hand, the ventilation support plate and the support plate seat can be spaced apart to improve the smoothness of airflow.

[0022] As described above, the utility model provides a ventilation base for an electrical cabinet, which has the following beneficial effects: by symmetrically providing ventilation support plates on both sides of the base, an airflow convection effect can be formed inside the electrical cabinet, and a V-shaped bracket is provided in one group of ventilation support plates, which can be used to improve the supporting stability of the ventilation support plates, and a ventilation wind screen is provided in the interval gap of the V-shaped bracket, so that a flow difference can be formed with the ventilation support plate on the other side, thereby improving the gas convection effect and accelerating the airflow convection speed inside the electrical cabinet.
