Abstract
Description
Technical Field
[0001] The present application relates to the field of fireproof windows, and in particular to a heat-insulating fireproof window. Background Art
[0002] In engineering, fireproof windows are defined as windows that, together with their frames, can meet the requirements of fire resistance stability and fire resistance integrity within a certain period of time. Fireproof windows should be used when lighting and ventilation are required on the exterior walls of two buildings with insufficient fire separation distance, or between spaces separated by fire walls.
[0003] Insulated fireproof windows are a type of fireproof windows that can not only maintain fireproof integrity within a specified period of time, but also have heat insulation functions. Since the fireproof effect will be lost if either the sash or the frame of the fireproof window fails, although some fireproof windows will be openable, in general, fireproof windows are not allowed to be opened privately. If opened, they must be equipped with electric self-closing devices (window closers) to enable them to automatically close in the event of a fire.
[0004] With regard to the above-mentioned related technologies, if equipped with an electric self-closing device, each opening and closing of the fireproof window will cause damage to the electric self-closing device. In particular, if the installation quality of the electric self-closing device is low, the loss each time it is opened and closed will be greater. Over a long period of time, the capacity of the electric self-closing device is difficult to guarantee, which can easily lead to accidental failure of the fireproof window. Utility Model Content
[0005] In order to make the fireproof window have sufficiently stable fireproof ability, the present application provides an insulating fireproof window.
[0006] The present application provides a heat-insulating fireproof window, which adopts the following technical solution:
[0007] An insulated fireproof window comprises a window frame and a window sash, wherein one side of the window sash is hinged to the window frame, a self-closing device is provided on the side of the window sash away from the hinge, a pulling rope and a transmission member for driving the pulling rope to move into the self-closing device are provided in the self-closing device, an electric motor for driving the transmission member is fixed in the self-closing device, one end of the pulling rope away from the self-closing device is fixedly connected to the window frame, and the length of the pulling rope outside the self-closing device is equal to or greater than the distance between the self-closing device and the window frame when the window sash is opened.
[0008] By adopting the above technical solution, the traction rope realizes the connection between the self-closing device and the window frame. When opening and closing naturally, the traction rope undergoes flexible deformation, and the self-closing device does not need to be started, thereby reducing the opening and closing losses of the self-closing device and the traction rope. After a fire occurs, the electric motor starts and drives the transmission part to retract along the traction rope into the self-closing device. If the fireproof window is in the open state at this time, the traction rope can pull the window sash to close into the window frame, thereby ensuring the stable fire protection capability of the fireproof window over a long period of time.
[0009] Optionally, the transmission member includes a winding shaft, the end of the traction rope located in the self-closing device is fixed on the winding shaft, and the output shaft of the electric motor is coaxially fixedly connected to the winding shaft.
[0010] By adopting the above technical solution, the electric motor can drive the winding shaft to rotate after being started, thereby realizing the winding of the traction rope, and the required space is relatively small.
[0011] Optionally, the transmission member includes a gear and a rack, the rack is slidably connected to the self-closing device along the extension direction of the self-closing device, the output shaft of the electric motor is fixedly connected to the gear, and the gear is meshed with the rack.
[0012] By adopting the above technical solution, the electric motor drives the gear to rotate after starting, and the gear can drive the rack to slide, so as to pull the traction rope into the self-closing device, and the pulling speed of the traction rope is faster.
[0013] Optionally, the self-closing device is provided with a backup power supply for supplying power to the electric motor.
[0014] By adopting the above technical solution, the presence of a backup power supply can prevent the automatic closing ability of the fireproof window when the external power supply is accidentally damaged by fire, thereby further enhancing the stability of the fireproof ability of the fireproof window.
[0015] Optionally, a smoke sensor is provided in the self-closing device, and the smoke sensor is used to control the start-up of the electric motor.
[0016] By adopting the above technical solution, the smoke sensor can quickly sense the smoke conditions in the environment to achieve the function of automatic pre-opening.
[0017] Optionally, a temperature sensor is provided in the self-closing device, and the temperature sensor is used to control the start-up of the electric motor.
[0018] By adopting the above technical solution, the low temperature sensor can quickly sense the ambient temperature conditions and also realize the function of automatic pre-start.
[0019] Optionally, the traction rope is a fireproof rope and the inner wall of the self-closing device is covered with an insulating layer.
[0020] By adopting the above technical solution, the fireproof rope material enables the traction rope to withstand flames and ensure the locking ability of the fireproof window. At the same time, the insulation layer can also reduce the heat exchange inside and outside the self-closing device, thereby reducing the impact of the high temperature of the flame on the electric motor, backup power supply and other components in the self-closing device, ensuring its stable operation and improving fire protection stability.
[0021] Optionally, an indicator light is provided on the surface of the self-closing device, and the indicator light is started synchronously with the electric motor.
[0022] By adopting the above technical solution, the indicator light is started synchronously with the electric motor. If the indicator light is on, it can warn nearby people not to manually open the fireproof window and to evacuate as soon as possible.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. The traction rope realizes the connection between the self-closing device and the window frame. When opening and closing naturally, the traction rope is flexibly deformed, and the self-closing device does not need to be started, thereby reducing the opening and closing loss of the self-closing device and the traction rope; after a fire occurs, the electric motor starts and drives the transmission member to retract along the traction rope into the self-closing device. If the fireproof window is in the open state at this time, the traction rope can pull the window sash to close into the window frame, thereby ensuring the stable fire protection ability of the fireproof window over a long period of time;
[0025] 2. The existence of a backup power supply can prevent the automatic closing capability of the fireproof windows when the external power supply is accidentally damaged by fire, further enhancing the stability of the fireproof capability of the fireproof windows.

[0030] The present application is further described in detail below in conjunction with all the accompanying drawings.
[0031] The embodiment of the present application discloses a heat-insulating fireproof window.
[0032] Embodiment 1:
[0033] Reference Figure 1A heat-insulating fireproof window includes a window frame 1 and a window sash 2. One side of the window sash 2 is hinged to the window frame 1 by a hinge, so that the window sash 2 can rotate relative to the window frame 1 to facilitate the opening or closing of the window. On the side of the window sash 2 away from the hinge, a self-closer 3 is provided. A pull rope is provided inside the self-closer 3, and a transmission member 32 for driving the pull rope to move into the self-closer 3 is also included. The end of the pull rope 31 away from the self-closer 3 is fixedly connected to the window frame 1. When a fire occurs, the pull rope 31 is used to pull the window sash 2 to close the fireproof window.
[0034] Reference Figure 1 and Figure 2 Inside the self-closer 3, an electric motor 33 is fixedly arranged, and the electric motor 33 is used to drive the transmission member 32 to move, and apply tension to the window sash 2 through the traction rope 31. In particular, the length of the traction rope 31 outside the self-closer 3 is designed to be equal to or greater than the distance between the self-closer 3 and the window frame 1 when the window sash 2 is in a fully open state. Such a design utilizes the flexible nature of the traction rope 31. No matter how much the window sash 2 is opened, the traction rope 31 can have a sufficient length without entering or exiting the self-closer 3, and without the transmission member 32 working, thereby reducing wear during natural opening and closing, and ensuring the stable fire protection capability of the fireproof window over a long period of time.
[0035] Reference Figure 1 and Figure 2 In order to enable the fireproof window to close automatically in advance when a fire occurs, a smoke sensor 35 is installed in the automatic shutter 3 in this embodiment to control the start of the electric motor 33. When the smoke sensor 35 detects that the smoke exceeds the standard, it can control the start of the electric motor 33. The electric motor 33 can be connected to an external power supply. However, in order to prevent the external power supply from being disconnected due to a fire, a backup power supply 34 is installed in the automatic shutter 3 in this embodiment. This backup power supply 34 can provide continuous power supply to the electric motor 33 when the external power supply is damaged due to an accident such as a fire, so as to ensure that the automatic closing function of the fireproof window will not be affected.
[0036] Reference Figure 1 and Figure 2 In other embodiments, a temperature sensor 36 may be used instead of the smoke sensor 35 to detect the ambient temperature to control the start of the electric motor 33. If higher accuracy is required, the smoke sensor 35 and the temperature sensor 36 may be used simultaneously, and one of the two sensors may be triggered to control the start of the electric motor 33. Of course, other more common sensors may also be used.
[0037] Reference Figure 1 and Figure 2After the electric motor 33 is started, the traction rope 31 can be driven through the transmission member 32. In this embodiment, the transmission member 32 includes a reel 321. The end of the traction rope 31 located in the self-closing device 3 is fixed to the reel 321, and the output shaft of the electric motor 33 is coaxially fixedly connected with the reel 321. When the electric motor 33 is started, the rotation of its output shaft will drive the reel 321 to rotate synchronously, thereby realizing the reeling action of the traction rope 31, pulling the window sash 2 to close into the window frame 1.
[0038] Reference Figure 1 and Figure 2 In order to prevent the fire window from failing quickly due to fire, the traction rope 31 is made of fireproof rope material, and a heat-insulating layer 37 is also covered on the inner wall of the self-closing device 3. The materials of the fireproof rope and the heat-insulating layer 37 can be made of mature materials at present, and this embodiment will not be elaborated in detail. In this way, the materials of the traction rope 31 and the electric motor 33 in the self-closing device 3 have strong fire resistance and high temperature resistance, ensuring a continuous and stable fire prevention effect.
[0039] Reference Figure 1 and Figure 2 The surface of the self-closing device 3 is also provided with an indicator light 38, which can be connected in series with the electric motor 33 to achieve synchronous start. When the electric motor 33 is started, the indicator light 38 will also light up, thereby warning nearby personnel not to manually open the fireproof window through a visual signal and to evacuate the scene as soon as possible.
[0040] The working principle of the embodiment 1 of the present application is as follows: when a fire occurs, the electric motor 33 will start quickly, and the traction rope 31 will be reeled up through the reel 321 to move it into the self-closing device 3. During this process, if the fireproof window is in an open state, the traction rope 31 will pull the window sash 2 to automatically close it into the window frame 1, thereby realizing the rapid closing of the fireproof window. The presence of the backup power supply 34 ensures that the fireproof window can maintain a stable automatic closing capability even when the external power supply is damaged. The synchronous activation of the indicator light 38 provides an intuitive visual warning, which enhances the safety of the fireproof window.
[0041] Embodiment 2:
[0042] Reference Figure 3, the main difference between this embodiment and embodiment 1 lies in the specific implementation of the transmission member 32. In this embodiment, the transmission member 32 includes a gear 322 and a rack 323. Specifically, the rack 323 is slidably connected to the self-closing device 3 along the extension direction of the self-closing device 3. The output shaft of the electric motor 33 is fixedly connected to the gear 322, and a meshing relationship is formed between the gear 322 and the rack 323. When the electric motor 33 is started, its output shaft will drive the gear 322 to rotate, and then drive the rack 323 to slide along the extension direction of the self-closing device 3. This transmission method has a faster pulling speed, and the closing response speed of the fireproof window is faster.
[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
