[0002] Doors and windows are divided into enclosing components or partition components according to their location. They have different design requirements and must have functions such as thermal insulation, heat insulation, sound insulation, waterproofing, and fire prevention. For example, fireproof doors and windows are required on the exterior walls of two buildings where the fire separation distance is insufficient.

[0003] At present, fireproof doors and windows are mainly fireproofed by internal fireproof materials, but the opening and closing of doors and windows are all manually operated by users. When a fire occurs outside the building, if the user is not at home and the doors and windows are open, in order to prevent the external fire from spreading indoors, the doors and windows need to be closed. However, at this time, the doors and windows still need to be closed manually, resulting in the inability to close them in the first time, which makes the risk of external fire entering the room exist, thereby causing unexpected dangers.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4 A fireproof intelligent door and window automatic opening and closing device comprises a window frame 1, two window doors 2 are hingedly connected to the side wall of the window frame 1, glass 3 is installed on the side wall of the window door 2, and a fixing frame 4 is fixedly connected to the inner side wall of the window frame 1 away from the window door 2. It should be noted that the side walls of the window door 2 and the fixing frame 4 close to each other are provided with high temperature resistant sealing pads to ensure the sealing of the window door 2 after closing.

[0023] The self-opening and closing mechanism includes two grooves 5 opened on the side wall of the window frame 1 away from the window door 2, the two grooves 5 correspond to the two window doors 2 one by one, the inner wall of the groove 5 is rotatably connected with a lead screw 9, and the side wall of the lead screw 9 is threadedly connected with a plurality of sliders 10, the inner wall of the window frame 1 is opened with a plurality of slide grooves 6 corresponding to the plurality of sliders 10 one by one, the inner wall of the slide groove 6 is slidably connected with a first rod 7, the side wall of the first rod 7 away from the slide groove 6 is rotatably connected to the side wall of the window door 2 through the second rod 8, the side wall of the first rod 7 away from the second rod 8 is rotatably connected to the side wall of the slider 10 through the third rod 11, the inner wall of the groove 5 is fixedly connected with a slide rod 15, and the side wall of the slide rod 15 is slidably connected to the side walls of the plurality of sliders 10.

[0024] A motor 12 is fixedly connected to the bottom of the groove 5, a first gear 13 is fixedly connected to the movable end of the motor 12, a second gear 14 is fixedly connected to the side wall of the lead screw 9, and the first gear 13 and the second gear 14 are meshed.

[0025] Further, such as Figure 3 As shown, when the motor 12 rotates clockwise, the first gear 13 drives the lead screw 9 to rotate counterclockwise through the second gear 14, and then the slider 10 slides upward, so that the third rod 11 drives the window door 2 to rotate outward through the first rod 7 and the second rod 8, and the door and window are opened. When the motor 12 rotates counterclockwise, the first gear 13 drives the lead screw 9 to rotate clockwise through the second gear 14, and then the slider 10 slides downward, so that the third rod 11 drives the window door 2 to rotate inward through the first rod 7 and the second rod 8, and the door and window are closed.

[0026] A temperature sensor 16 is embedded on the upper side wall of the window frame 1 close to the window door 2. The motor 12 and the temperature sensor 16 are electrically connected to an external power supply through a PLC control mechanism.

[0027] Furthermore, when the temperature sensor 16 senses that the external temperature has reached its set value, the set value of the temperature sensor 16 can be set to 70-100°C. At this time, the PLC control mechanism will drive the motor 12 to rotate counterclockwise through the sensing signal of the temperature sensor 16, so that the window door 2 rotates inward to automatically close the door and window, thereby preventing the outside fire from entering the room without manual closing, avoiding the problem in the prior art that the door and window cannot be closed in the first time, so that there is a risk of the outside fire entering the room, thereby causing unexpected danger.

[0028] An on / off switch 18 is installed on the side wall of the window frame 1 away from the window door 2. The motor 12 and the on / off switch 18 are electrically connected to an external power source through a PLC control mechanism.

[0029] Furthermore, when the temperature sensor 16 does not sense a temperature signal, the user presses the on / off switch 18 to control the clockwise and counterclockwise rotation of the motor 12 through the PLC control mechanism, thereby automatically opening and closing the window 2.

[0030] It should be noted that the control procedures of the temperature sensor 16 and the on / off switch 18 controlling the rotation of the motor 12 through the PLC control mechanism are both existing mature technologies and are very common control means, which will not be elaborated here.

[0031] A sealing plate 17 is attached to the inner wall of the groove 5. The cross section of the sealing plate 17 is T-shaped. The side wall of the sealing plate 17 is connected to the side wall of the window frame 1 by a plurality of screws, so as to facilitate the maintenance of the self-opening and closing mechanism.

[0032] During the use of the door and window, the user can press the opening and closing switch 18 to control the clockwise and counterclockwise rotation of the motor 12 through the PLC control mechanism to automatically open and close the window 2. Specifically:

[0033] When the motor 12 rotates clockwise, the first gear 13 drives the lead screw 9 to rotate counterclockwise through the second gear 14, and then the slider 10 slides upward, so that the third rod 11 drives the window 2 to rotate outward through the first rod 7 and the second rod 8, and the door and window are opened. When the motor 12 rotates counterclockwise, the first gear 13 drives the lead screw 9 to rotate clockwise through the second gear 14, and then the slider 10 slides downward, so that the third rod 11 drives the window 2 to rotate inward through the first rod 7 and the second rod 8, and the door and window are closed.

[0034] When the temperature sensor 16 senses that the external temperature has reached its set value, it means that the external temperature is high and the fire is large. At this time, the PLC control mechanism will drive the motor 12 to rotate counterclockwise through the sensing signal of the temperature sensor 16, so that the window door 2 rotates inward and the door and window are automatically closed, thereby preventing the external fire from entering the room. There is no need for manual closing, which avoids the problem in the prior art that the door and window cannot be closed in the first time, so that there is a risk of the external fire entering the room, thereby causing unexpected dangers, and in the subsequent period, you only need to press the opening and closing switch 18 again to open the window door 2 again.

[0035] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
