A fan-blade window for firefighting comprises a window body, a motor, a controller, a large belt wheel, a small belt wheel and a conveying belt. A movable opening is formed in the middle of thick glass arranged in the middle of the window body, a rotating shaft and fan blades connected with the rotating shaft are arranged in the movable opening, a circle formed with the distance between the vertexof the blade edge of each fan blade and the circle center part as the radius and with the circle center part as the circle center is externally tangent to the plane where kraft paper is located, andthe plane where the kraft paper is located is parallel to the blade surfaces of the fan blades. One end of the rotating shaft is connected with the driving end of the motor. The controller comprises ametal shell, an input power line, an output power line, an insulating column and a temperature sensing piece. According to the design, air can be automatically discharged when a fire disaster occurs,the fire loss can be conveniently reduced, and the fan-blade window for firefighting is simple in structure, high in practicability and low in cost.
Description
technical field [0001] The invention relates to a fire prevention device, in particular to a leaf window for fire protection, which is especially suitable for automatically exhausting air through the window to reduce fire losses in the event of a fire, and has a simple structure, strong practicability, and low cost. advantage. Background technique [0002] At present, the windows sold on the market and used in daily life are all manually opened, and the windows cannot be opened automatically according to the changes in the environment outside the window itself to achieve automatic ventilation, which is very inconvenient, especially when a fire occurs indoors, if the window can At this time, the automatic exhaust is not only beneficial to reduce the indoor temperature, but also helps to discharge the smoke caused by the indoor fire, which is very beneficial to reduce the loss of the fire. [0003] Chinese patent, the authorized announcement number is CN201148801Y, and the au...
