TECHNICAL FIELD
[0001] The utility model belongs to the technical field of the warehouse roof, especially a novel steel sheet warehouse roof natural ventilation device. BACKGROUND
[0002] The existing warehouse roof ventilation system is usually provided on the warehouse roof cover plate. The warehouse roof is provided with a ventilation device for auxiliary ventilation, but the adjustment function is weak. If the opening blockage is poor, it is easy to be affected by external rain and snow, and then enter the steel sheet warehouse. If the sealing is good, the ventilation effect is weak.
[0003] After searching, a novel warehouse roof ventilation and air exchange structure (CN117178754A) is found. The warehouse roof is conical, and the top surface of the warehouse roof is provided with natural ventilation openings at the edge in the ring direction. The top center of the warehouse roof is provided with an air induction unit in the ring direction. When the warehouse roof needs ventilation and air exchange, the air induction unit is started and operated to exhaust air outside the warehouse roof. Negative pressure is formed at the top center of the warehouse roof, which drives the air inside the warehouse roof to flow to the top center of the warehouse roof. The air outside the warehouse is introduced into the warehouse through the natural ventilation opening, and the exhaust air is filled, so that the air inside the warehouse is quickly exchanged and cooled. According to the principle of hot air rising, the hot air between the two adjacent natural ventilation openings will also naturally gather to the top center of the warehouse roof, and the air introduced through the natural ventilation opening is filled, so that the air exchange and cooling of the hot air are also effectively realized. The warehouse roof is provided with a ventilation device for auxiliary ventilation, but the adjustment function is weak. If the opening blockage is poor, it is easy to be affected by external rain and snow, and then enter the steel sheet warehouse. If the sealing is good, the ventilation effect is weak. SUMMARY
