DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0024] Referring to Figures 1, 2 and 4, a rainproof roof 7 is fixedly installed on the top of the distribution cabinet body 2, a solar photovoltaic panel 8 is fixedly installed on the top of the rainproof roof 7, a ventilation plate 9 is movably installed on the bottom of the rainproof roof 7, a plurality of air holes 10 are provided at the bottom of the ventilation plate 9, an exhaust fan 11 is fixedly installed in the inner cavity of the rainproof roof 7, the exhaust fan 11 and the solar photovoltaic panel 8 are electrically connected, a plurality of fixing rods 12 are fixedly installed on the left and right sides of the inner wall of the distribution cabinet body 2, a layer plate 13 is movably installed on the top of the fixing rod 12, and a plurality of through holes 14 are provided on the surface of the layer plate 13.

[0025] The above scheme is adopted: through the setting of the rainproof roof 7, on rainy days, rainwater falling on the rainproof roof 7 will drip to both sides and will not flow into the inside of the distribution cabinet body 2. Through the setting of the solar photovoltaic panel 8, the exhaust fan 11 can be powered to save energy consumption, thereby improving the energy saving and environmental protection of the overall structure.

[0026] Referring to Figures 1, 2 and 5, a stainless steel hinge 15 is fixedly installed on the left side of the front of the distribution cabinet body 2, an inspection door 16 is fixedly installed on the right side of the stainless steel hinge 15, a sealing ring 17 is fixedly installed on the back of the inspection door 16, a sealing groove 18 is opened on the front of the distribution cabinet body 2, and the sealing ring 17 can be inserted and matched with the sealing groove 18, and a plug rod 19 is fixedly installed at the bottom of the base 1.

[0027] The above scheme is adopted: through the coordinated use of the sealing ring 17 and the sealing groove 18, the sealing performance of the distribution cabinet is improved, thereby increasing the practicality of the overall waterproof structure of the distribution cabinet. Through the setting of the plug rod 19, the distribution cabinet body 2 can be fixed without contacting the ground, avoiding the penetration of surface water from the bottom during rainy days.

[0028] Working principle: When in use, fix the plug rod 19 in a suitable position, leaving a part of the plug rod 19 out of the ground so that the base 1 does not directly contact the ground. The internal temperature of the distribution cabinet gradually increases during operation, and the exhaust fan 11 is started to exchange the hot air inside the distribution cabinet body 2 with the cold air from the outside through the ventilation holes 5. On rainy days, rainwater will not float into the interior of the distribution cabinet body 2 through the ventilation holes 5 of the inclined structure, ensuring a dry working environment inside the cabinet. The inspection door 16 is in the closed state, and the sealing ring 17 on the back of the inspection door 16 and the sealing groove 18 on the front of the cabinet are plugged together to improve the overall airtightness of the distribution cabinet and enhance the overall waterproof performance.
