DETAILED DESCRIPTION

[0017] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined invention purpose, the specific embodiments, structures, features and effects according to the present application will be described in detail below in conjunction with the drawings and preferred embodiments.

[0018] Because, modern high-rise buildings are generally equipped with central fresh air system and mechanical smoke exhaust system, the former is responsible for daily ventilation, and the latter is started when fire occurs, and smoke is extracted remotely through fan and pipeline network, however, doors and windows are the most direct channel for air exchange between inside and outside of the building, and their role in fire is always passive - only closed or opened, and closed blocks smoke exhaust, and opened forms an air inlet channel, which cannot provide an effective path for early smoke exhaust; leading to the complete dependence of smoke exhaust on centralized mechanical system, but its inherent defects of long exhaust path, large resistance and decreasing efficiency with distance are particularly prominent when the fire expands, which easily leads to smoke accumulation in the room and rapid increase of suffocation risk of personnel, therefore, at the critical early stage of fire, the building lacks a widely distributed and rapidly responsive smoke exhaust emergency channel based on indoor air quality to make up for the problems of response lag and insufficient efficiency of traditional centralized smoke exhaust system.

[0019] For this purpose, please refer to Figures 1-8 The present application provides a safe fireproof aluminum alloy door and window, which comprises a door and window frame 1, a window sash 2, a sensing module and an opening and closing mechanism. The outer side of the door and window frame 1 is connected with the building wall, and the indoor side is provided with the sensing module and is electrically connected with the opening and closing mechanism. The other side is provided with an arc groove, and the window sash 2 is embedded in the arc groove to form a closed seal. The opening and closing mechanism comprises an inner support, a reverse opening piece and a limiting rod 7. One end of the window sash 2 is hinged with the inner support, and the other end is hinged with the reverse opening piece. One end of the limiting rod 7 is sleeved with the reverse opening piece, and the other end is slidably connected with the door and window frame 1, which forms a fulcrum for one end of the window sash 2. The sensing module collects the oxygen content and carbon monoxide content to obtain an abnormal instruction and starts the opening and closing mechanism based on the abnormal instruction. The inner support drives the window sash 2 to swing to form an air inlet channel. The reverse opening piece drives the limiting rod 7 to displace to switch the fulcrum and drive the window sash 2 to open reversely to form a smoke exhaust channel.

[0020] Specifically, the present application solves the problem of low smoke exhaust efficiency caused by the fact that doors and windows can only be passively closed or opened based on indoor air quality by setting an induction module to monitor the changes in indoor oxygen content concentration and carbon monoxide content concentration in real time. The induction module includes an inner support control box 3 and a reverse opening control box 5 arranged on the side of the door and window frame 1 away from the sash window. The reverse opening control box 5 and the inner support control box 3 are electrically connected to the floor fire fighting system. The inner support control box 3 includes an oxygen sensor, a first data module and a first control module connected in sequence. The oxygen sensor is used to collect indoor air oxygen content data near the door and window. The first data module contains an oxygen content data table. The oxygen sensor feeds back the collected data to the first data module. The first data module compares the data with the oxygen content data table to obtain an oxygen abnormal instruction or an oxygen qualified instruction and feeds back to the floor fire fighting system. The reverse opening control box 5 includes a carbon monoxide sensor, a second data module and a second control module connected in sequence. The carbon monoxide sensor also collects indoor carbon monoxide content data near the door and window. The second data module contains a carbon monoxide content table. The carbon monoxide sensor feeds back the collected carbon monoxide content data to the second data module to obtain a carbon monoxide abnormal instruction and a carbon monoxide normal instruction and feeds back to the floor fire fighting system. Thus, the floor fire fighting system can obtain the indoor air quality in the fire area based on the air quality information fed back by the widely distributed doors and windows. The first control module of the inner support control box 3 is electrically connected to the floor fire fighting system and is also connected to a remote control. The remote control is mainly used by the user to remotely manually control the opening or closing of the window sash 2 for daily ventilation adjustment. In addition, the second control module of the reverse opening control box 5 is also connected to the fire linkage controller signal. When receiving the fire alarm signal sent by the floor fire fighting system, the reverse opening control box 5 is automatically triggered. That is, the floor fire fighting system collects oxygen abnormal instructions and carbon monoxide abnormal instructions from each door and window. The first control module of the inner support control box 3 is independently controlled by the user through the remote control for daily ventilation. If necessary, for example, when a fire breaks out on a floor, the smoke exhaust is upward, the floors below the fire floor can be opened for ventilation under the control of the floor fire fighting system to reduce the spread of smoke and increase the oxygen content in the escape floors. The floor fire fighting system can participate in the smoke exhaust action of the second control module of the reverse opening control box 5 and the ventilation action of the first control module of the inner support control box 3.

[0021] When used normally, the indoor oxygen concentration is lower than the set threshold or the user needs to ventilate, the remote control can be used to start the first electric push rod 4 to drive the inner support to swing the window sash 2 to open to a preset angle to form a Figure 3The air inlet channel is downward, the floor is located at a high level, the air flow direction is from top to bottom, fresh air can flow into the room at low speed, air flow impact is avoided, when a fire occurs, the floor fire control system control triggers the reverse opening control box 5, the second control module starts the reverse opening piece, the reverse opening piece drives the limiting rod 7 to displace, the fulcrum of the window sash 2 is changed and the window sash 2 is continuously driven, so that the window sash 2 is rotated to the preset angle as shown in the figure, an indoor-to-outdoor inclined smoke exhaust channel is formed, the inclination angle can effectively guide the smoke to rise along the inclined plane and be quickly exhausted, accumulation of smoke in the room is avoided, external air flow backflow is prevented, and smoke exhaust stability is ensured. Figure 4 It should be noted that, in order to avoid that the smoke exhaust channel is exhausted after a certain amount of smoke, the indoor oxygen is reduced to form a negative pressure, which is not conducive to the continuous smoke exhaust, in this process, the central fresh air system and the mechanical smoke exhaust system are continuously working, the fresh air system automatically supplies air to the room through the preset air inlet channel to maintain the indoor air pressure balance, ensure the continuous and efficient smoke exhaust process, at the same time, avoid the smoke backflow or the smoke exhaust efficiency due to the negative pressure, the mechanical smoke exhaust system cooperates with the smoke exhaust channel formed by the reverse opening window sash 2 to direct the high-temperature smoke to be quickly exhausted, improve the overall smoke exhaust effect, and ensure the smooth development of personnel evacuation and fire rescue. Compared with the existing doors and windows which only serve as ventilation and air exchange, the application additionally uses a number of doors and windows in the building as smoke exhaust openings which are linked with the fire and can be expanded at any time, thereby reducing the accumulation of harmful smoke in the room.

[0022] Specifically, the inner support piece includes a first electric push rod 4, the side of the window sash 2 facing the first electric push rod 4 is symmetrically provided with a strip-shaped groove, four protruding columns are arranged in the strip-shaped groove, when the window sash 2 is closed with the door and window frame 1, there are accommodating spaces between the vertical two sides of the window sash 2 and the door and window frame 1, the lower parts of the two accommodating spaces are respectively provided with the first electric push rod 4, the first electric push rods 4 are symmetrically arranged, the first electric push rod 4 includes a rod body and a telescopic rod which is displaced along the radial direction of the rod body, one end of the rod body is hinged to the door and window frame 1 and is electrically connected with the first control module, in addition, the telescopic rod is hinged to the protruding column below the window sash 2, when the window sash 2 is in the vertical closed state, the two first electric push rods 4 are in the vertical state, there is a certain friction force between the bottom of the window sash 2 and the door and window frame 1 and the weight of the window sash 2, so as to overcome the instability, when the first electric push rod 4 is started, the window sash 2 is pushed to open outward to a preset angle, forming an initial air inlet channel, the window sash 2 and the door and window frame 1 adopt an outward pushing mode, that is, the upper part of the window sash 2 serves as a fulcrum, the lower part swings a certain angle around the fulcrum, forming an air inlet channel, the purpose of using this mode is that, on the one hand, it can avoid the situation that the window sash 2 is directly blown to produce abnormal sound when the outdoor wind force is large in a high-rise building, on the other hand, as shown in the figure, the window sash 2 is in the outward opening state, the window sash 2 is provided with glass through glue, which can effectively prevent rainwater from flowing into the room with the wind, and can form natural flow guiding by using the air flow direction from bottom to top, thereby improving the ventilation efficiency. Figure 3 When the window sash 2 is in the outward opening state, the window sash 2 is provided with glass through glue, which can effectively prevent rainwater from flowing into the room with the wind, and can form natural flow guiding by using the air flow direction from bottom to top, thereby improving the ventilation efficiency.

[0023] In order to solve the problem that the door and window are difficult to expand into the smoke exhaust passage when the fire occurs, the application proposes the reverse opening interval, specifically, the reverse opening piece includes the second electric push rod 6, the inner push rod 61 and the hinged rod 62 and the connecting rod 8, the second electric push rod 6 also includes the rod body and the inner push rod 61 which is displaced along the radial direction of the rod body, one end of the rod body is hinged to the door and window frame body 1 and is electrically connected with the second control module, the inner push rod 61 is internally provided with a buffer cavity away from one end of the rod body, and is externally provided with an annular groove, one end of the hinged rod 62 is hinged to the protruding column above the window sash 2, and the other end is slidably connected to the buffer cavity, wherein the rod body of the second electric push rod 6 is located above, and the inner push rod 61 is located below, in addition, it is also necessary to point out that the door and window frame body 1 is internally provided with two vertical sliding grooves on both sides, the two ends of the two sliding grooves are respectively communicated with the arc grooves and continue to extend, the limiting rods 7 are symmetrically arranged, the two limiting rods 7 are respectively slidably connected in the two vertical sliding grooves, and a strip-shaped channel is respectively formed between the sliding grooves and the accommodating space, one end of the connecting rod 8 penetrates through the strip-shaped channel and is fixed to one side of the limiting rod 7, and the other end is embedded in the annular groove on the inner push rod 61 close to the indoor side. When the fire occurs, the second electric push rod 6 is started, the inner push rod 61 moves downward, since the buffer cavity exists between the inner push rod 61 and the hinged rod 62, the inner push rod 61 continues to move downward but does not first contact the hinged rod 62, when the inner push rod 61 contacts the protruding column, the displacement between the inner push rod 61 and one end of the hinged rod 62 is completed, when the inner push rod 61 moves downward, the connecting rod 8 and the limiting rod 7 are pushed downward through the annular groove, the limiting rod 7 moves from the upper part of the vertical sliding groove to the lowermost part, the fulcrum formed by the limiting rod 7 above the window sash 2 changes to the fulcrum below the window sash 2, at this time, the inner push rod 61 continues to push the hinged rod 62, and the second electric push rod 6 pulls the window sash 2 through the hinged rod 62 to adjust the opening angle.

[0024] As a further optimization scheme of the application, the manual push handle 9 is further arranged, the manual push handle 9 is arranged at the lower middle part of the indoor side of the window sash 2, so that the user can manually open the window when the power is off or the control system is invalid or the remote controller is not found, the pushing force needs to be greater than the resistance of the window sash 2 to swing back around the upper fulcrum and the friction between the window sash 2 and the door and window frame body 1, and the window sash 2 is supported and locked by the first electric push rod 4 after being opened to the maximum angle, this supporting mode is supported by the prior art, and will not be described here.

[0025] As a further optimization scheme of the present application, the movable rod 10 is arranged between the first electric push rod 4 and the second electric push rod 6, one end of the movable rod 10 is hinged to the middle of the door and window frame 1, and the other end is hinged to the middle of the window sash 2, forming a linkage support structure. When the second electric push rod 6 drives the window sash 2 to open, the movable rod 10 rotates synchronously with the window sash 2 to expand, enhancing the stability of the overall structure; in addition, the movable rod 10 forms an inclined support after the window sash 2 is fully opened, effectively dispersing the stress caused by the weight of the window sash 2, avoiding deformation or fatigue damage of the hinge point due to long-term stress, the movable rod 10 limits the opening angle of the window sash 2, and also equivalent to a mechanical locking device, ensuring the stable hanging state of the window sash 2 in the air.

[0026] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content without departing from the scope of the present application, and any equivalent embodiments with equivalent changes are equivalent to the above.
