[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figure 1-5A fireproof safety cabinet includes a cabinet body 1, a cabinet door 2, a support plate 3, a partition 4, a storage plate 5, a limiting plate 6, and a ventilation duct 7. The cabinet body 1 consists of an outer shell, an inner shell, and filling material. The outer shell and inner shell are made of thickened cold-rolled steel plates, and the filling material is cement-based fireproof mortar. A one-way valve is installed at the top of the cabinet body 1. The cabinet door 2 is installed on the cabinet body 1, and a first sealing ring and a second sealing ring are installed on the cabinet door 2. The first and second sealing rings are thermal expansion sealing rings. A support plate 3 is horizontally installed in the lower middle part of the cabinet body 1. A partition 4 is installed between the top of the support plate 3 and the top plate of the cabinet body 1. A storage plate 5 is installed between one side of the partition 4 and one side of the cabinet body 1. Fixing rings are installed at both ends of the corresponding positions on the inside of the cabinet body 1 and the side of the partition 4. The storage plate 5 is connected to the fixing rings on the inside of the cabinet body 1 and the side of the partition 4 by fixing blocks at both ends. In addition, a smoke detector is installed on one side of the cabinet body 1, and the smoke detector is located below the fixing ring.
[0022] The partition 4 is provided with multiple rotating grooves, which are located above the shelf 5. A baffle is movably connected to the rotating groove through a rotating column. Multiple limiting plates 6 are provided between the other side of the partition 4 and the inner side of the cabinet 1. A storage box is installed between two corresponding limiting plates 6. A slot is opened on one side of the storage box, which corresponds to the position of the rotating groove in the partition 4. The other side is connected to the ventilation duct 7 through a connecting groove. A fan is fixedly installed under the support plate 3 on one side of the ventilation duct 7. A nitrogen tank is fixed on the right side of the fan, and the output end of the nitrogen tank is connected to the ventilation duct 7.
[0023] In this embodiment, when a fire occurs inside the cabinet, the first and second sealing rings on the cabinet door 2 will expand when heated, sealing the cabinet 1. At this time, the fire will be blocked by the double-layer shell structure and filling material of the cabinet 1, preventing the fire from spreading outside the cabinet 1. Subsequently, the smoke detector will detect the generated smoke. At this time, the baffle in the partition 4 will rotate in the rotating groove through the rotating column, opening the rotating groove. Then, the fan under the support plate 3 will start, blowing the nitrogen in the nitrogen tank into the storage box along the ventilation duct 7. Since the storage boxes are all set on the limiting plate, and the limiting plate corresponds to each partition, the dry powder in the storage box will be blown by the wind and enter the cabinet 1 through the slot on one side of the storage box and the rotating groove on the partition 4. At this time, the one-way valve at the top of the cabinet 1 will open, and the oxygen in the cabinet 1 will be gradually replaced by nitrogen and discharged through the one-way valve, extinguishing the fire.
[0024] In this invention, by setting up a cabinet, a storage box, and a ventilation duct, the cabinet prevents the fire from spreading outside, while the fan sprays dry powder from the storage box and nitrogen from the nitrogen tank into the cabinet through the ventilation duct to extinguish the fire.
[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
