Heat dissipation mechanism of electric power engineering equipment

The utility model provides a heat dissipation mechanism of electric power engineering equipment, which relates to the technical field of electric power equipment and comprises a distribution box mainbody, a filter plate and a clamping sleeve, the top end of the distribution box main body is fixedly connected with a sun shield through a nut, and the top end of the sun shield is provided with a groove. According to the distribution box, the filtering sleeve is installed, when the four exhaust fans exhaust hot air in the distribution box body, external air can enter the distribution box body through the filtering sleeve to be subjected to air circulation cooling, and impurities and dust in the external air easily block filtering holes of the filtering sleeve for a long time; when the air enters the filter sleeve, the fan blades are driven to rotate, and the fan blades rotate to enable the filter sleeve to rotate through the balls and the clamping sleeve, so that the outer surface of thefilter sleeve can be scrap
