The invention discloses a fireproof board comprising a fireproof board body. The fireproof board body comprises a base plate, a mounting cavity is formed in the middle of the base plate, the inner side end of the mounting cavity is open, and a heat insulation board is installed at the open end of the mounting cavity in a sealing mode. An inflation layer is disposed at the inner side end of the heat insulation board, an inflation chamber is formed in the inflation layer, the inflation chamber is filled with inert gas, more than one gas guiding tube is inserted into the inflation chamber in a sealing mode, and the gas guiding tubes penetrate through the inflation layer. Corresponding inserting holes are formed in the heat insulation board facing the gas guiding tubes, the left ends of the inserting holes run through the right ends of the inserting holes, the extending ends of the gas guiding tubes are inserted into the inserting holes, the outer side ends of the gas guiding tubes form agap layer, the gap layer is internally filled with a flammable sealing layer in a sealing mode, and the gas outlet ends of the gas guiding tubes are sealed by the flammable sealing layer. The fireproof board not only has a quite good heat insulation capacity, but also can effectively prevent fire in a fire, effectively block the spread of the entire fire, can extinguish the fire to a certain extent, and improve the indoor safety.

The invention discloses a multi-unit 3D printing manufacturing system capable of achieving continuous production. The multi-unit 3D printing manufacturing system comprises a multi-unit 3D printer setcomposed of a plurality of 3D printers, an automatic spraying mechanism is arranged in each 3D printer, and a smoke alarming mechanism capable of detecting fire behavior signals in the corresponding 3D printer is electrically connected to one side of each automatic spraying mechanism; and each 3D printer comprises a printer shell, an X-axis movement mechanism, a Y-axis movement mechanism, a Z-axismovement mechanism, a material spraying mechanism, a printing consumable, a printing platform and a lifting platform, each Z-axis movement mechanism is located in the corresponding printer shell andfixedly connected with the corresponding Y-axis movement mechanism through the corresponding lifting platform, each Y-axis movement mechanism is connected with the corresponding X-axis movement mechanism, and each X-axis movement mechanism is located over the corresponding printing platform and fixedly connected with the corresponding material spraying mechanism. The multi-unit 3D printing manufacturing system capable of achieving continuous production has the following beneficial effects that the multi-unit 3D printing manufacturing system not only has an automatic fire extinguishing function, but also can strip printed models from the printing platforms without damaging the models.

The invention relates to a hand-throw heat colloidal sol extinguisher which comprises a spherical shell, a heat colloidal sol generator and an ignition system, wherein the heat colloidal sol generator is placed in the spherical shell; an insulation material chamber and a cooling chamber are arranged between the heat colloidal sol generator and the spherical shell; the spherical shell is provided with the ignition system of which the front end extends into the heat colloidal sol generator; a hole in the heat colloidal sol generator is communicated with the cooling chamber ; a spout is formed in the spherical shell; the hole in the heat colloidal sol generator is communicated with the spout in the spherical shell through the cooling chamber. After being generated in the heat colloidal sol generator, heat colloidal sol enters the cooling chamber via the hole and then enters atmosphere through the spout after being cooled by coolants in the cooling chamber. The hand-throw heat colloidal sol extinguisher has the advantages of convenience in carrying and simplicity in operation, and can be widely applied to fire extinguishment in various relative sealing spaces.

The invention discloses an electric vehicle with a fire prevention device, which belongs to the technical field of electric vehicle batteries. An electric vehicle with a fire prevention device comprises a packaging case and a plurality of battery packs. The inner side wall of the packaging case is fixedly connected with a plurality of sides. There are multiple separators fixedly connected to the packaging shell, and the separators are located between the side plates, which can delay the battery from igniting, and can also prevent the harmful liquid in the battery from volatilizing into the air. By limiting the lateral expansion of the battery, In this way, the iron wire and iron sheet on the barbed wire net can be used to prevent the expansion of the battery, delay the appearance of open flames, and buy precious time for rescue or escape. In the outside world, and the adsorption ball will expand after absorbing the liquid, so as to break the side plates and partitions made of ceramic materials, so that the adsorption ball can form a film on the burning material under the action of the open flame to isolate the air, thereby To achieve the role of fire extinguishing.
