[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the terminal equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet needs to be ventilated and heat-dissipated inside during operation. The "ventilation mechanism of a distribution cabinet" disclosed by the publication number "CN217281810U" has solved the technical disadvantage that the heat inside the distribution cabinet cannot be quickly removed. However, in actual use, ventilation mechanisms of similar structures still have many defects. For example, most of them can only ventilate and heat the entire interior of the distribution cabinet, and do not have the function of separate ventilation and heat dissipation according to the situation. When the distribution cabinet is in use, some electrical equipment will generate serious heat itself, and the overall ventilation method of the distribution cabinet cannot effectively cool it down and dissipate the heat. When operating in a long-term hot state, it will accelerate aging or even damage. For this reason, we have designed a ventilation mechanism for a distribution cabinet to solve the above problems.

[0022] Based on the above-mentioned structural setting, the ventilation mechanism of the distribution cabinet is composed of a heat dissipation mechanism 1 and a guide mechanism 2, wherein the heat dissipation mechanism 1 can be the heat dissipation ventilation mechanism of the distribution cabinet, with the help of the heat dissipation mechanism 1, the entire interior of the distribution cabinet can be ventilated and heat-dissipated, the guide mechanism 2 is a transmission guide mechanism for ventilation gas, with the help of the guide mechanism 2, the electrical equipment with serious heat generation in the distribution cabinet can be individually blown and heat-dissipated. Specifically, during operation, the fan cover 101 is installed in a slot pre-opened on the back or side wall of the distribution cabinet, and the two sets of ventilation motors 4 installed inside the fan cover 101 drive the ventilation fan blades 401 to rotate to draw external air into the distribution cabinet, so that the ventilation motor 4 and the ventilation fan blades 401 can be used to ventilate and heat the entire interior of the distribution cabinet, and the fixing seat 103 can be used to ventilate the front of the fan cover 101 when it is installed and the outer wall of the distribution cabinet. The elbow 102 can guide and redirect the airflow blown in by the ventilation motor 4 and the ventilation fan blades 401, and the top of the assembly cover 201 is assembled with the bottom of the elbow 102, so that the ventilation airflow can be diverted through the three groups of shaping hoses 203, and the valve tube 3 can control the opening and closing of the three groups of shaping hoses 203, and the shaping hoses 203 can be bent and shaped during operation, so that the electrical equipment with severe heat generation in the distribution cabinet can be individually blown and cooled through the shaping hoses 203 and the exhaust hood 204, which greatly improves the efficiency and quality of the mechanism in ventilating and cooling the electrical equipment with severe heat generation, avoids the situation of accelerated aging or damage when it works under high temperature for a long time, and ensures the safety of electrical equipment that is prone to heat when operating in the distribution cabinet.

[0023] Furthermore, an assembly ring 109 is fixedly installed at the bottom of the elbow 102, and a docking ring 202 used in conjunction with the assembly ring 109 is fixedly installed at the top of the assembly cover 201.
