The protective shell 501 is fixedly connected to the distribution cabinet body 1. One end of the protective shell 501 is fixedly connected with a filter screen 502. A connecting frame 503 is fixedly connected in the protective shell 501. A fan 504 is fixedly connected to the connecting frame 503. The cooperation of the protective shell 501 and the filter screen 502 is used to protect the fan 504, thereby effectively preventing foreign objects from entering.

[0021] A cabinet door 2 is provided at one end of the distribution cabinet body 1. The cabinet door 2 is rotatably connected to the distribution cabinet body 1 through a hinge. A top plate 3 is fixedly connected to the top of the distribution cabinet body 1. The top of the insertion post 4 is fixedly connected to the rain shield 7. The rain shield 7 is conical. The bottom of the insertion post 4 is inserted into the slot 8. When the insertion post 4 is inserted into the slot 8, the limiting post 9 will be inserted into the insertion post 4, thereby assisting in fixing the rain shield 7 for subsequent fixation of the rain shield 7 on the top plate 3 by the limiting device 6.

[0022] At the top of the distribution cabinet body 1, there is a top plate 3 and a rain shield 7. At the bottom of the rain shield 7, there is an insertion post 4. On the top plate 3, there is a slot 8, and a limiting device 6 and a limiting post 9 are arranged on the top plate 3. The limiting post 9 is fixedly connected in the slot 8, and the top of the limiting post 9 is inserted into the insertion post 4. The guide rod 607 is inserted into the top plate 3. The magnetic block 603 and the first bevel gear 608 are both fixedly connected to the guide rod 607. One end of the wheel rod 601 is inserted into the guide rod 607, and the slider 602 is slidably connected to the guide rod 607. The slider 602 is inserted into the top plate 3, and the slider 602 is fixedly connected to one end of the wheel rod 601; by sliding the slider 602, it is convenient for the wheel rod 601 to drive the guide rod 607 to rotate, so as to facilitate the subsequent separation of the arc-shaped block 606 from the insertion into the insertion post 4.

[0023] The limiting device 6 includes a wheel rod 601. One end of the wheel rod 601 is provided with a slider 602 and a guide rod 607. The guide rod 607 is provided with a first bevel gear 608 and a magnetic block 603. On one side of the first bevel gear 608, there is a second bevel gear 609 meshing with it. At the top of the second bevel gear 609, there is a main line wheel 610.

One end of the arc-shaped block 606 passes through the top plate 3 and is inserted into the insertion post 4. The guide wheel 604 is lapped on the steel wire rope 611. One end of the spring 605 is fixedly connected to the arc-shaped block 606. The guide wheel 604 and the spring 605 are both installed in the top plate 3; the elastic force of the spring 605 is used to insert the arc-shaped block 606 into the insertion post 4, so as to fix the rain shield 7 on the top plate 3, and the guide wheel 604 plays a role in turning the steel wire rope 611, so as to facilitate the subsequent pulling of the arc-shaped block 606 by the steel wire rope 611 for contraction.

[0025] The working principle of the present utility model is as follows: When the plug post 4 is inserted into the slot 8, the rain shield 7 is assisted in being limited by the limit post 9. Through the cooperation of the arc-shaped block 606 and the spring 605, the rain shield 7 is fixed on the top plate 3. Then, by pulling and rotating the wheel rod 601, through the cooperation of the guide rod 607, the first bevel gear 608 and the second bevel gear 609, one end of the steel wire rope 611 is wound around the main line wheel 610, and the steel wire rope 611 will pull to disengage the arc-shaped block 606 from the plug post 4. Subsequently, the slider 602 is inserted into the top plate 3, so as to facilitate the staff to remove the rain shield 7. And by starting the fan 504, the air circulation inside and outside the power distribution cabinet body 1 is accelerated, and the cooperation of the filter screen 502 and the protective shell 501 is used to prevent external sundries from affecting the normal operation of the fan 504.

[0026] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense.
