Detailed Description

The utility model is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the utility model and are not limiting of the utility model. It should be noted that, for convenience of description, only the portions related to the utility model are shown in the drawings.

It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. The utility model will be described in detail below with reference to the drawings in connection with embodiments.

The ventilation type low-voltage power distribution cabinet is characterized in that, as shown in fig. 1, a rotary ventilation pipe 2 is arranged at the corner of the front end part in the cabinet body 1, the upper end part of the rotary ventilation pipe 2 penetrates through the upper end face of the cabinet body 1 through a bearing and is connected with a rotary motor 3 fixed on the cabinet body 1 through a belt pulley, and the lower end part of the rotary ventilation pipe 2 is fixed on the bottom end face of the cabinet body 1 through a bearing.

As shown in fig. 2, the lower end surfaces of the two rotary ventilation pipes 2 are connected with two vertical pipes on the horizontally placed air inlet pipe 5 through the rotary joint 4, one end of the air inlet pipe 5 is connected with the air supply device 6, the ventilation pipes 21 on the two rotary ventilation pipes 2 are mutually vertical, namely, the ventilation pipe 21 on the rotary ventilation pipe 2 positioned at the left end part of the cabinet body 1 is positioned on the rear end surface thereof, and the ventilation pipe 21 on the rotary ventilation pipe 2 positioned at the right end part of the cabinet body 1 is positioned on the left end surface thereof.

When the rotary ventilating duct is used, the air supply device 6 and the rotary motor 3 are started, so that the air supply device 6 supplies air outside the cabinet body 1 into the air supply pipe 5, and the air enters the rotary ventilating duct 2 through the air supply pipe 5 because the air supply pipe 5 is communicated with the rotary ventilating duct 2;

meanwhile, after the rotary motor 3 is started, the rotary ventilation pipe 2 rotates in the cabinet body 1, air outside the cabinet body 1 enters the cabinet body 1 through the through hole 21 after entering the rotary ventilation pipe 2, and air outside the cabinet body 1 rotates in the cabinet body 1 and is introduced into the cabinet body 1, so that air can be blown to any place of the cabinet body 1, heat dissipation of components in the cabinet body 1 is facilitated, and redundant air is discharged from the ventilation holes in the cabinet body 1 due to the fact that the air continuously enters the cabinet body 1.

Because the through hole 21 is the ventilation pipe, and the angle between the through hole 21 and the rotary ventilation pipe 2 is 30-60 degrees, and simultaneously because the heated air can rise, when the wind on the through hole 21 blows out at an upward certain angle, the air with higher temperature can be more favorably dispersed.
