Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a non-powered heat dissipation mechanism of a distribution box. Background Art

[0002] A distribution box (distribution cabinet) is an electrical device used to distribute electrical energy in a power distribution system, protect electrical equipment and its lines, distribute power from a substation or main power source to various electrical devices or areas, and ensure the rational distribution of electricity. The distribution box plays a key role in the electrical system. It not only helps to efficiently distribute electrical energy, but also protects the safety of equipment and personnel. It is an indispensable part of the modern power system.

[0003] However, most traditional distribution boxes use electric fans for heat dissipation. After a period of use, the fan will cause performance degradation or even failure due to dust, dirt or other reasons. Regular cleaning and maintenance are required to ensure its normal operation. In addition, the fan will generate certain noise during operation to dissipate heat, which may interfere with the working environment.

[0004] Therefore, those skilled in the art provide a non-powered heat dissipation mechanism for a distribution box to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the present invention is to solve the shortcomings existing in the prior art, and to propose a non-powered heat dissipation mechanism for a distribution box. Compared with most traditional distribution boxes, the distribution box is respectively provided with a ventilation mechanism and a heat exhaust mechanism. Under the action of the wind gathering groove, the surrounding wind force is gathered, so that the driving blades can rotate with the rotating rod under the action of the wind force, and then the suction fan blades convert the airflow inside and outside the distribution box, so that the distribution box can perform non-powered heat dissipation in the presence of wind, and then the ventilation and heat dissipation area of ​​the distribution box is increased by opening the through slots, ensuring smoother air circulation and avoiding air flow obstruction, thereby improving the non-powered heat dissipation ability of the distribution box in the absence of wind, and thus improving the heat dissipation effect and applicable scope of the distribution box.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0019] Through the above technical solution, by providing a fixing plate, each required component of the distribution box can be installed and fixed in the box shell.

[0020] Furthermore, the through slot is opened in the middle of the outer wall of the rear end of the box shell;

[0021] With the above technical solution, the heat in the box shell can be discharged to the outside more effectively by providing the through grooves.

[0022] Furthermore, the fixing bracket is fixedly connected to the outer wall of the rear end of the box shell;

[0038] Compared with most traditional distribution boxes, this distribution box is respectively provided with a ventilation mechanism 6 and a heat exhaust mechanism 8, which gather the surrounding wind force under the action of the wind gathering groove, so that the driving blade 606 can rotate with the rotating rod 605 under the action of the wind force, and then the suction fan blade 607 converts the airflow inside and outside the distribution box, so that the distribution box can perform unpowered heat dissipation in the presence of wind, and then increase the ventilation and heat dissipation area of ​​the distribution box by opening the through slot 803, ensuring smoother air circulation and avoiding air flow obstruction, thereby improving the unpowered heat dissipation ability of the distribution box in the absence of wind, and thus improving the heat dissipation effect and applicable range of the distribution box.

[0039] The lower ends of the outer walls on both sides of the box shell 1 are provided with cable ducts 5. By providing the cable ducts 5, external cables can be connected to the distribution box. The ventilation chute 601 is provided at the upper end of the middle part of the outer walls on both sides of the box shell 1.

The gathered airflow drives the driving blade 606 to make the rotating rod 605 rotate with the suction fan blade 607. The suction fan blade 607 circulates air inside and outside the box shell 1 through the ventilation chute 601 and the exhaust port 602.
