The utility model discloses an electric automatic power distribution cabinet, which is shown in fig. 1 and 2, and comprises a cabinet body 1 with an opening at one side, a cabinet door 11 rotatably connected to the opening of the cabinet body 1, and a cooling mechanism 2 arranged above the cabinet body 1, wherein the cabinet door 11 can open and close the opening of the cabinet body 1. The cooling mechanism 2 comprises an exhaust support 21 arranged above the cabinet body 1, a fan 22 arranged in the exhaust support 21 and a motor 23 for driving the fan 22 to rotate, wherein the exhaust support 21 is in a circular tube shape with openings at the upper end and the lower end, the fan 22 is rotationally connected in the exhaust support 21, the motor 23 is fixed in the exhaust support 21 by bolts, the motor 23 is positioned at one end, close to the cabinet body 1, of the fan 22, an output shaft of the motor 23 is coaxially connected with the fan 22, so that the fan 22 is driven to rotate, and the motor 23 can be electrically connected with a power supply circuit in the cabinet body 1. An air outlet communicated with the inner cavity of the cabinet body 1 is arranged above the cabinet body, an air exhaust support 21 is arranged at the air outlet, and the inner cavity of the air exhaust support 21 is communicated with the inner cavity of the air outlet. The air in the cabinet body 1 is driven to flow to the outside through the air outlet by the fan 22, so that the temperature in the cabinet body 1 is reduced, the environmental temperature of the electronic components in the cabinet body 1 is reduced, and the aging speed of the electronic components is reduced.

As shown in fig. 2, since the cabinet body 1 is directly placed outdoors, in the case of rainy weather, rainwater falls on the upper end of the cabinet body 1 and flows into the air outlet along the upper end surface of the cabinet body 1, the upper end of the cabinet body 1 is further welded with the air outlet pipe 12 coaxially arranged with the air outlet, and the inner wall of the air outlet pipe 12 is flush with the inner wall of the air outlet. The baffle ring 24 is coaxially fixed on the outer wall of the exhaust bracket 21, the lower end of the exhaust bracket 21 can be embedded in the exhaust pipe 12, the outer wall of the exhaust bracket 21 can be abutted with the inner wall of the exhaust pipe 12, and the lower end face of the baffle ring 24 can be abutted with the upper end face of the exhaust pipe 12. The step is formed at the opening of the upper end of the air outlet 11 by the air outlet pipe 12, so that rainwater falling on the upper end of the cabinet body 1 cannot flow towards the air outlet 11 along the upper end surface of the cabinet body 1, the probability that the rainwater enters the cabinet body 1 is reduced, and electronic components in the cabinet body 1 are not easy to damage.

As shown in fig. 2, during the process of falling, the rainwater still falls on the connection between the abutting ring and the exhaust pipe 12, so that the rainwater still flows into the exhaust pipe 12. Therefore, the flange 25 is coaxially fixed at the lower end of the baffle ring 24, the flange 25 extends downward, a gap is left between the flange 25 and the outer wall of the exhaust bracket 21, the flange 25 can be sleeved on the outer wall of the exhaust pipe 12, and the side wall of the flange 25 close to the axis can be abutted with the outer wall of the exhaust pipe 12. The outer wall of the flange 25 is circumferentially and threadedly connected with a plurality of fastening bolts 26, and the fastening bolts 26 penetrate through the flange 25 and are abutted against the outer wall of the exhaust pipe 12. Therefore, when the rainwater moves towards the baffle ring 24, the flange 25 can guide the rainwater, so that the rainwater moves downwards along the flange 25 and flows onto the cabinet body 1 along the exhaust pipe 12, and the rainwater is not easy to move into the cabinet body 1.

As shown in fig. 2, the upper part of the cabinet body 1 is further provided with a rain shield 3 for preventing rainwater from flowing into the exhaust support 21, the rain shield 3 comprises a first rain shield 31 and a second rain shield 32 which are arranged from inside to outside, the first rain shield 31 is disc-shaped, one end far away from the axis is inclined upwards, and the diameter of the first rain shield 31 is larger than that of the exhaust support 21. The second rain shield 32 is inclined downwards away from the first rain shield 31, so that when the fan 22 drives the air in the cabinet 1 to flow towards the outside, the flowing air contacts with the rain shield 3 and moves along the rugged rain shield 3 in a direction away from the axis of the rain shield 3, so that the air can move more rapidly in a direction away from the exhaust pipe 12.

As shown in fig. 2, the motor 23 and the like need to be replaced after the fan 22 is used for a long time, and the weather shield 3 is directly shielded above the fan 22, which affects the replacement of the exhaust bracket 21, the fan 22 and the like. Therefore, three connecting rods 33 are circumferentially arranged below the rain shield 3, the upper ends of the connecting rods 33 are rotationally connected to the rain shield 3, and the connecting rods 33 can rotate to intersect with the axis of the rain shield 3. The lower end of the side wall of the connecting rod 33, which is close to the axis of the rain shield 3, is fixed with a clamping block 34, the clamping block 34 extends upwards, and a gap is reserved between the upper end of the clamping block and the connecting rod 33. A plurality of clamping grooves 251 are circumferentially formed in the inner wall of the flange 25, the clamping grooves 251 penetrate through the lower end face of the flange 25, the clamping blocks 34 can be self-contained between the exhaust pipe 12 and the flange 25, parts of the clamping blocks 34 can be embedded in the clamping grooves 251, and the side wall, close to the rain shield 3, of the clamping blocks 34 can be in contact with the outer wall of the exhaust pipe 12. In the process of separating the exhaust bracket 21 from the exhaust pipe 12, the rain shield 3 can be taken off from the cabinet 1 together, and then the rain shield 3 can be separated from the exhaust bracket 21 so as to replace the exhaust bracket 21, the fan 22 and the motor 23.

As shown in fig. 2, in order to stably connect the connecting rod 33 with the exhaust support 21 during the process of installing and dismantling the exhaust support 21, a friction pad 35 is provided on the side wall of the connecting rod 33 close to the axis of the weather shield 3, the friction pad 35 is a rubber pad in this embodiment, the friction pad 35 can be abutted against the outer wall of the flange 25, so that the connection strength between the connecting rod 33 and the flange 25 is increased, and the weather shield 3 can stably maintain the connection with the exhaust support 21 during the process of removing and installing the exhaust support 21 from the exhaust pipe 12, so that the process of dismantling and installing the exhaust support 21 is more stable.

In order to enable air inside and outside the cabinet body 1 to flow more easily, the side wall of the cabinet body 1 is also provided with a plurality of air inlets 13 communicated with the inner cavity of the cabinet body 1, the air inlets 13 are all provided with rain-shielding shutters 14, the lower ends of the rain-shielding shutters 14 incline towards the direction away from the cabinet body 1, when the fan 22 drives the air inside the cabinet body 1 to flow outwards, the air outside the cabinet body 1 enters the cabinet body 1 through the air inlets 13, so that the air with lower external temperature is utilized to cool the inside of the solid, and the environmental temperature of the electronic components is reduced.

The implementation principle of the embodiment is as follows: the motor 23 drives the fan 22 to rotate, thereby driving the air inside the cabinet 1 to circulate with the outside and reducing the air inside the cabinet 1. When the motor 23 is damaged by long-time operation, the fastening bolt 26 is loosened and the exhaust bracket 21 is removed from the exhaust duct 12, the motor 23 and the like are replaced, and then the exhaust bracket 21 is continuously mounted on the exhaust duct 12 and the fastening bolt 26 is tightened.

The embodiments of the present utility model are all preferred embodiments of the present utility model, and are not intended to limit the scope of the present utility model in this way, therefore: all equivalent changes in structure, shape and principle of the utility model should be covered in the scope of protection of the utility model.
