Description

Technical Field

[0001] The present invention relates to the technical field of fire-resistant windows, and more particularly to an energy-saving fire-proof escape device for fire-resistant windows. Background Art

[0002] Fire-resistant windows refer to a type of window that can fully meet the requirements of fire resistance stability and fire resistance integrity within a certain period of time. When a fire occurs, fire-resistant windows can isolate the fire source and smoke inside the house.

[0003] With the rapid development of the economy, the structural form of residential buildings has also undergone tremendous changes, from low-rise buildings with 5-6 floors to high-rise buildings with dozens of floors. The escape of high-rise buildings in the event of a fire has become an urgent problem that needs to be solved.

[0004] Most existing fire-resistant windows are designed to be converted into ladders or equipped with safety belts that can be lowered to allow people to evacuate from a fire. While these methods can facilitate escape from a fire, they are only suitable for low-rise buildings with relatively low ceilings.

[0005] When a fire breaks out in a high-rise building, neither the escalators nor the seatbelts are long enough to safely descend from dozens of floors to the ground for escape. During a fire, those on the upper floors have no choice but to wait for firefighters at open fire-resistant windows. However, when open, air currents push fire and smoke toward the windows, potentially harming those waiting there. Furthermore, the windows' inherent ability to isolate fire and smoke is underutilized. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide an energy-saving fire escape device with fire-resistant windows, which provides an escape platform with a protective function for people to wait for escape, and closes the fire-resistant windows during the waiting process to isolate the fire source and smoke, avoiding harm to people.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] The fire escape device of claim 1, wherein the fire escape device comprises a fire window unit installed inside a wall and an escape platform unit installed outside the wall. The fire window unit comprises an upper window assembly and a lower window assembly rotatably connected by a connecting piece, and a mounting assembly mounted on the bottom of the lower window assembly; the mounting assembly comprises a window guardrail installed on the outside of the wall and a drive mounting plate arranged at the end of the vertical window guardrail, the top of the window guardrail is rotatably connected to the lower window assembly through a window frame rotating rod, the top of the window guardrail is installed on the side away from the drive mounting plate, and the side wall of the drive mounting plate is installed with a drive assembly; the escape platform unit comprises a platform control switch installed on the mounting assembly, a platform mounting plate installed on the outside of the wall, and a rotating platform rotatably mounted on the platform mounting plate, the rotating platform is installed with a connecting escalator unit that can be connected with a fire ladder on the side close to the wall, and the rotating platform is installed with a protective handrail unit that can protect the rotating platform on the side away from the wall.

[0009] The present invention is further configured as follows: the driving assembly includes a driving cylinder installed on the side wall of the driving mounting plate, the driving cylinder is installed inside the wall and electrically connected to a driving control switch, and the driving control switch is installed on the inner side wall of the wall away from the escape platform unit; the driving cylinder is rotatably connected to a transmission rod on the side close to the window guardrail, and the transmission rod is sleeved on the end of the window frame rotating rod.

[0010] The present invention is further configured as follows: the lower window assembly includes a lower rotating window frame configured as a rectangular frame structure and a window frame rotating rod arranged at the bottom of the lower rotating window frame; the window frame rotating rod is rotatably installed on the top of the window guardrail and connected to the lower rotating window frame.

[0011] The present invention is further configured as follows: the upper window assembly includes an upper rotating window frame rotatably connected to a lower rotating window frame, the upper rotating window frame is configured as a rectangular frame structure having the same length as the lower rotating window frame, and two groups of opening and closing windows are symmetrically arranged inside the upper rotating window frame; and multiple groups of connecting parts are provided at the connection between the bottom of the upper rotating window frame and the lower rotating window frame.

[0012] By adopting the above technical solution, pressing the drive control switch installed on the side wall controls the drive cylinder to rotate the transmission rod, which in turn rotates the window frame rotating rod. The window frame rotating rod further drives the lower rotating window frame to rotate relative to the window guardrail. During this process, the lower rotating window frame rotates relative to the upper window assembly through the connecting member, ultimately forming an L-shaped platform structure between the upper and lower window assemblies, providing a reliable escape route for personnel.

[0013] The present invention is further configured as follows: a circular rotation groove is provided on the platform mounting plate, a rotation assembly is installed in the middle of the platform mounting plate, the rotation assembly is electrically connected to the platform control switch, and a group of first matching rods adapted to the shape of the rotation groove are provided at each end of the rotating platform.

[0014] The present invention is further configured as follows: the rotating assembly includes a rotating motor installed on the side wall of the platform mounting plate, and the output end of the rotating motor is connected to a horizontal rotating rod arranged along the horizontal direction; each end of the horizontal rotating rod is connected to a group of first supporting rotating rods, and the end of each group of the first supporting rotating rods is rotatably connected to the second matching rod arranged in the middle of the rotating platform through the second supporting rotating rod.

[0015] By adopting this technical solution, the bottom of the lower window assembly abuts the control switch during rotation, applying pressure to the control switch, triggering it. This causes the rotary motor to rotate the horizontal rotating rod, which in turn rotates the first supporting rotating rod, which in turn, through the connection of the second mating rod, drives the rotating platform. The rotating platform rotates from a vertical position parallel to the sidewalls and the wall to a horizontal position perpendicular to the sidewalls and the wall, thereby raising the rotating platform and providing an escape platform for evacuees to stand and await rescue.

[0016] The present invention is further configured as follows: two groups of protective handrail units are symmetrically arranged about the axis of the rotating platform, each group of the protective handrail units includes a mounting base rod installed on the side wall of the rotating platform, and the top of the mounting base rod is rotatably connected to a plurality of groups of rotating connecting rods; wherein the two groups of rotating connecting rods are equidistantly arranged.

[0017] The present invention is further configured as follows: the top of the rotating connecting rod is rotatably connected to a rotating part, the top of the rotating part is connected to a handrail rod, the handrail rod is configured as a cylindrical structure with a length consistent with the installation base rod, and a group of fasteners are provided at its end; the fasteners are sleeved on the side wall of the rotating part, and the top is connected to the side wall of the handrail rod.

[0018] By adopting this technical solution, pressing the latch releases the rotating member, and then pushing and pulling the handrail causes it to move along the length of the rotating platform, driving the rotating member and the rotating connecting rod connected to it to rotate. When the rotating connecting rod rotates to be perpendicular to the mounting base, pressing the latch again locks the rotating member, and the rotating connecting rod and handrail now form a containment structure.

[0019] The present invention is further configured as follows: the overlapping escalator unit includes several groups of escalator pedals arranged on parallel rotating platforms, each group of escalator pedals is provided with a group of pedal rotating rods at both ends; and the two ends of the pedal rotating rods are rotatably connected to a group of connecting rotating rods.

[0020] The present invention is further configured as follows: a group of escalator steps close to the rotating platform are connected to the rotating platform, and a rotating handle is rotatably connected to the side wall thereof; a group of escalator steps on the side away from the rotating platform are connected to a group of connecting platforms at their ends, and the installation direction of the connecting platforms is perpendicular to the installation direction of the escalator steps.

[0021] By adopting the above technical solution, by turning the rotating handle, several groups of connecting rods can be driven to rotate synchronously. During the rotation process of the connecting rods, they move away from the pedal rotating rods, thereby realizing the opening of the escalator pedals and changing the overlapping escalator units from a contracted state to an open state.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When evacuating, the upper and lower window assemblies rotate into an L-shaped platform, creating an escape route. This simultaneously triggers the platform to rise, allowing personnel to transfer from the fireproof window unit to the platform to await rescue. While waiting, the fireproof window unit isolates the fire and smoke inside the room, preventing them from spreading and potentially harming personnel. It also prevents the fireproof window unit's heat-resistant properties from damaging and potentially falling components.

[0024] 2. Protective handrails are installed, using a rotating connecting rod and handrails to form a barrier structure to protect personnel from both sides of the rotating platform. They provide stable support for personnel in dangerous situations such as those caused by high-altitude wind disturbances and fear of heights, and also prevent personnel from accidentally falling from the rotating platform and causing further injury.

[0025] 3. Install a connecting ladder unit. After the fire ladder reaches the target, turn the handle to open the connecting ladder unit from a retracted state, forming an evacuation channel. At the same time, the connection between the connecting platform and the fire ladder is improved, which improves the reliability of the connection between the connecting ladder unit and the fire ladder, improves the safety of evacuation, helps eliminate the fear caused by heights, and speeds up the evacuation of personnel.

[0039] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0040] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0041] See also Figure 1-9 , the present invention provides the following technical solutions:

[0042] For example 1, please refer to Figure 1-4 and Figure 7-8 , including a fireproof window unit 1 installed inside the wall and an escape platform unit 2 installed outside the wall. When a fire occurs, escaping personnel can escape through the fireproof window unit 1. After the fireproof window unit 1 is opened, the escape platform unit 2 rises, and the escaping personnel can move to the escape platform unit 2 to wait for rescue. At the same time, the fireproof window unit 1 is closed to isolate the fire source and smoke, thereby preventing the fire source and smoke from causing harm to the escaping personnel while waiting for rescue.

[0043] See also Figure 1-3 The fireproof window unit 1 includes a mounting assembly 11, a window guardrail 111, a drive mounting plate 112, an upper window assembly 12, an upper rotating window frame 121, an opening and closing window 122, an opening and closing handle 123, a lower window assembly 13, a lower rotating window frame 131, a window frame rotating rod 132, a connector 14, a drive assembly 15, a drive cylinder 151, a transmission rod 152, and a drive control switch 16. The upper window assembly 12 and the lower window assembly 13 are mounted inside the wall, and are rotatably connected to each other via the connector 14. The mounting assembly 11 is mounted on the bottom of the lower window assembly 13. The mounting assembly 11 includes a window guardrail 111 mounted on the outside of the wall and a drive mounting plate 112 arranged perpendicular to the end of the window guardrail 111. The window guardrail 111 can provide support for the lower window assembly 13. The top of the window guardrail 111 is rotatably connected to the lower window assembly 13 via a window frame rotating rod 132, allowing the lower window assembly 13 to rotate relative to the window guardrail 111. A platform control switch 21 is mounted on the top of the window guardrail 111, away from the drive mounting plate 112. During the rotation of the lower window assembly 13, pressure can be applied to the platform control switch 21 to trigger it. The drive mounting plate 112 is mounted inside the wall, and a drive assembly 15 is mounted on the side wall. The drive assembly 15 includes a drive cylinder 151 mounted on the side wall of the drive mounting plate 112. The drive cylinder 151 is mounted inside the wall and electrically connected to a drive control switch 16, which is mounted on the inner side wall of the wall away from the escape platform unit 2. The drive control switch 16 controls the operation of the drive cylinder 151. A drive rod 152 is rotatably connected to the drive cylinder 151 on the side of the window guardrail 111. The drive rod 152 is sleeved onto the end of the window frame rotating rod 132. The extension and retraction of the driving cylinder 151 can synchronously drive the transmission rod 152 to rotate. During the rotation of the transmission rod 152, the window frame rotating rod 132 can be synchronously driven to rotate. Finally, through the rotation of the window frame rotating rod 132, the lower window assembly 13 is driven to rotate relative to the window guardrail 111.

[0044] See also Figure 1-3 The lower window assembly 13 includes a lower pivoting window frame 131 configured as a rectangular frame structure and a window frame rotating rod 132 disposed at the bottom of the lower pivoting window frame 131. The lower pivoting window frame 131 is mounted within the wall. During normal use of the fire-resistant window, the lower pivoting window frame 131 is tightly attached to the wall. The window frame rotating rod 132 is pivotally mounted on the top of the window guardrail 111 and connected to the lower pivoting window frame 131. The end of the window frame rotating rod 132 away from the escape platform unit 2 is connected to the transmission rod 152. As the window frame rotating rod 132 rotates relative to the window guardrail 111, it can simultaneously drive the lower pivoting window frame 131 to rotate, thereby enabling the lower pivoting window frame 131 to open and close. The upper window assembly 12 includes an upper pivoting window frame 121 pivotally connected to a lower pivoting window frame 131. The upper pivoting window frame 121 is configured as a rectangular frame structure with the same length as the lower pivoting window frame 131. Multiple sets of connectors 14 are provided at the bottom of the upper pivoting window frame 121 where it connects to the lower pivoting window frame 131. The connectors 14 enable rotation between the upper and lower pivoting window frames 121, 131. Two sets of retractable windows 122 are symmetrically arranged within the upper pivoting window frame 121. Each set of retractable windows 122 is equipped with an opening and closing handle 123. When the fire-resistant window is in normal use, the retractable windows 122 can be opened using the opening and closing handles 123 to achieve normal ventilation.

[0045] See also Figure 1 and Figure 4 The escape platform unit 2 includes a platform control switch 21 mounted on the mounting assembly 11, a platform mounting plate 22 mounted on the outside of the wall, and a rotating platform 23 rotatably mounted on the platform mounting plate 22. A rotating assembly 24 is mounted in the middle of the platform mounting plate 22 near the fireproof window unit 1. The rotating assembly 24 is electrically connected to the platform control switch 21, and the platform control switch 21 can control the operation of the rotating assembly 24. The platform mounting plate 22 is provided with a circular rotating groove 221, which is set at both ends of the platform mounting plate 22 and extends through the platform mounting plate 22. A set of first mating rods 231 are provided at each end of the rotating platform 23, each of which is shaped to match the rotating groove 221. The first mating rods 231 are inserted into the rotating groove 221 to achieve a rotational connection between the rotating platform 23 and the platform mounting plate 22. An abutment block is provided at the center of the top of the platform mounting plate 22 to ensure that the rotating function of the rotating platform 23 is not affected and to further ensure the reliability of the rotating platform 23 after it is lifted. A set of second matching rods 232 is respectively provided at both ends of the middle portion of the rotating platform 23 , and the rotating platform 23 and the rotating assembly 24 are connected via the second matching rods 232 .

[0046] See also Figure 1 and Figure 4The rotating assembly 24 includes a rotating motor 241 mounted on the side wall of the platform mounting plate 22. The output end of the rotating motor 241 is connected to a horizontal rotating rod 242 arranged in the horizontal direction. The rotating motor 241 can drive the horizontal rotating rod 242 to rotate. Each end of the horizontal rotating rod 242 is connected to a set of first supporting rotating rods 243. The first supporting rotating rods 243 are mounted on the outer wall of the horizontal rotating rod 242 and can rotate synchronously with the horizontal rotating rod 242. Each end of the first supporting rotating rod 243 is rotatably connected to a set of second supporting rotating rods 244. The ends of the second supporting rotating rods 244 away from the first supporting rotating rods 243 are rotatably connected to the second matching rod 232 located in the middle of the rotating platform 23. During the rotation of the first supporting rotating rod 243, it can synchronously drive the second cooperating rod 232 to rotate, and finally drive the second cooperating rod 232 to rotate, so that the rotating platform 23 is rotated from a vertical state in which the side wall is parallel to the wall to a horizontal state in which the side wall is perpendicular to the wall, thereby realizing the lifting of the rotating platform 23 and providing an escape platform for escaping personnel to stand and wait for rescue.

[0047] Specifically, when the fire-resistant window is in normal use, the lower rotating window frame 131 fits tightly against the wall, and personnel can open the two symmetrically arranged groups of opening and closing windows 122 through the two groups of opening and closing handles 123 to achieve normal ventilation function.

[0048] When a fire breaks out and escape is necessary, the driver can press the drive control switch 16 mounted on the wall side to control the drive cylinder 151 to rotate the transmission rod 152. This rotation of the transmission rod 152 also drives the window frame rotating rod 132 to rotate. Ultimately, the rotation of the window frame rotating rod 132 drives the lower rotating window frame 131 to rotate relative to the window guardrail 111, causing the lower window assembly 13 to rotate perpendicular to the wall side. During the rotation of the lower window assembly 13, the connector 14 rotates the lower window assembly 13 relative to the upper window assembly 12, ensuring that the upper window assembly 12 remains parallel to the wall side. Ultimately, the upper window assembly 12 and the lower window assembly 13 remain perpendicular to each other, forming an L-shaped platform structure between the upper and lower window assemblies 12, providing a reliable escape route for personnel.

[0049] During the rotation of the lower window assembly 13, its bottom abuts against the platform control switch 21, thereby applying pressure to the platform control switch 21 to trigger it. After the platform control switch 21 is triggered, the rotating motor 241 drives the horizontal rotating rod 242 to rotate, and the first supporting rotating rods 243 at both ends of the horizontal rotating rod 242 rotate synchronously with the horizontal rotating rod 242. During the rotation of the first supporting rotating rod 243, the second matching rod 232 is synchronously driven to rotate, which further drives the second matching rod 232 to rotate, and finally drives the rotating platform 23 to rotate. During the rotation of the rotating platform 23, the first matching rod 231 inserted into the rotating groove 221 rotates relative to the rotating groove 221, causing the rotating platform 23 to rotate from a vertical state with the side walls parallel to the wall to a horizontal state with the side walls perpendicular to the wall, thereby raising the rotating platform 23 and providing an escape platform for escaping personnel to stand and wait for rescue.

[0050] After the rotating platform 23 is raised, personnel can transfer from the L-shaped platform structure formed by the upper window assembly 12 and the lower window assembly 13 to the top of the rotating platform 23, where they can wait for fire rescue. After the personnel are transferred, they can push the lower window assembly 13 upward. The pressure on the lower window assembly 13 pushes the drive cylinder 151 to retract, and ultimately, the upper window assembly 12 and the lower window assembly 13 are restored to a sealed state under the action of the drive assembly 15 and the window frame rotating rod 132. While waiting for fire rescue on the rotating platform 23, personnel can fully utilize the fire-resistant properties of the fire-resistant windows to effectively isolate the fire and smoke inside the house, preventing fire and smoke from spreading to the windows and causing harm to personnel while waiting for rescue.

[0051] During escape, when the fireproof window unit 1 is opened to form an escape route, the rotating platform 23 can be triggered to rise synchronously, replacing the fireproof window unit 1 to form a safer and more reliable escape platform for people to wait for rescue. On the one hand, the fireproof window unit 1 can be used to isolate the fire and smoke inside the house, preventing the fire and smoke from spreading and causing harm to people. On the other hand, it can also prevent the fireproof window unit 1 from being damaged in heat resistance and the parts on it from falling and causing harm to people.

[0052] For example 2, please refer to Figure 1 、 Figure 5 and Figure 8This second embodiment makes the following improvements on the basis of the first embodiment: after the rotating platform 23 is raised, it can serve as an escape platform for people to wait for rescue on its top. However, the wind speed is high at high altitudes, and people standing on the rotating platform 23 are easily unstable due to wind disturbances. In addition, some people are afraid of heights, so the safety of people waiting for rescue on the rotating platform 23 cannot be guaranteed. Therefore, it is necessary to provide a protective handrail unit 3 to protect people on the rotating platform 23 and further ensure the safety of people waiting for rescue.

[0053] See also Figure 1 、 Figure 5 and Figure 8 A protective handrail unit 3 is installed on the side of the rotating platform 23 away from the wall to protect the rotating platform 23. Two groups of protective handrail units 3 are symmetrically arranged about the axis of the rotating platform 23. When personnel are waiting for rescue on the rotating platform 23, they can open the protective handrail units 3 to form a fence on both sides of the rotating platform 23, thereby improving the safety of the rotating platform 23. Each group of protective handrail units 3 includes a mounting base 31 installed on the side wall of the rotating platform 23. The mounting base 31 is arranged along the length direction of the rotating platform 23 and is connected to the rotating platform 23 at the bottom. The connection between the protective handrail unit 3 and the rotating platform 23 is achieved through the mounting base 31. Several groups of rotating connecting rods 32 are rotatably connected to the top of the mounting base 31. The two groups of rotating connecting rods 32 are equidistantly arranged, and each group of rotating connecting rods 32 can rotate relative to the mounting base 31. The top of each group of rotating connecting rods 32 is rotatably connected to a rotating member 34, and the top of the rotating member 34 is connected to a handrail rod 33. The handrail 33 is a cylindrical structure with the same length as the mounting base 31. A set of latches 35 are installed at its end. These latches 35 are mounted on the sidewalls of the rotating member 34 and connected to the sidewalls of the handrail 33 at their tops. Pressing the latches 35 allows the rotating member 34 to be released and locked. Once the rotating member 34 is released, the handrail 33 can be pushed or pulled, driving the multiple sets of rotating members 34 and the rotating connecting rod 32 at its bottom to rotate synchronously, ultimately rotating the rotating connecting rod 32 to a position perpendicular to the mounting base 31.

[0054] Specifically, after the personnel have been safely transferred to the rotating platform 23, they can release the rotating member 34 by pressing the latch 35, and then push and pull the handrail 33 to move the handrail 33 along the length of the rotating platform 23, driving the rotating member 34 and the rotating connecting rod 32 connected thereto to rotate. When the rotating connecting rod 32 rotates to be perpendicular to the mounting base 31, the latch 35 is pressed again to lock the rotating member 34, maintaining the vertical state of the rotating connecting rod 32. The enclosure structure formed by the rotating connecting rod 32 and the handrail 33 is used to protect the personnel from both sides of the rotating platform 23. In dangerous situations such as when a person is unstable due to high-altitude wind disturbances or when he is unstable due to fear of heights, the protective handrail unit 3 can be used to provide stable support for the person, while also preventing the person from accidentally falling from the rotating platform 23 and causing further injury.

[0055] For example three, please refer to Figure 1 、 Figure 6 and Figure 8-9 This third embodiment makes the following improvements based on the second embodiment. After a fire occurs, when fire rescue forces reach the escape point to initiate rescue operations, they typically extend the fire ladder to the escape platform, creating an evacuation channel. However, the fire ladder and the escape platform lack a reliable connection. Fear can prevent people from successfully escaping to the fire ladder or cause them to evacuate too slowly at high altitudes, increasing the risk of fire escape. Therefore, it is necessary to provide a connecting ladder unit 4 on the rotating platform 23 that can connect to the fire ladder, thereby improving the reliability of the connection with the fire ladder and accelerating evacuation.

[0056] See also Figure 1 、 Figure 6 and Figure 8-9 The rotating platform 23 is installed with a connecting ladder unit 4 on the side close to the wall, which can be connected to the fire ladder. After the rotating platform 23 is lifted, the connecting ladder unit 4 is in a state perpendicular to the side wall of the wall. After the fire rescue arrives, the connecting ladder unit 4 can be unfolded to connect with the fire ladder, thereby improving the reliability of the connection between the two and speeding up the evacuation of personnel. The connecting ladder unit 4 includes several groups of escalator pedals 42 arranged parallel to the rotating platform 23. Each group of escalator pedals 42 is provided with a group of pedal rotating rods 43 at both ends, and a group of connecting rotating rods 44 are rotatably connected to the two ends of the pedal rotating rods 43. A group of escalator pedals 42 close to the rotating platform 23 is connected to the rotating platform 23, and its side wall is rotatably connected to a rotating handle 41. A group of escalator pedals 42 on the side away from the rotating platform 23 is connected to a group of connecting platforms 45 at the end, and the installation direction of the connecting platforms 45 is perpendicular to the installation direction of the escalator pedals 42. By rotating the rotating handle 41, several groups of connecting rods 44 can be driven to rotate synchronously. During the rotation process, the connecting rods 44 can move away from the step rods 43, thereby realizing the opening of the escalator steps 42.

[0057] Specifically, when the fire ladder reaches the target, the person on the rotating platform 23 can rotate the rotating handle 41, driving the connecting rod 44 to move away from the step rod 43, gradually opening the escalator step 42, and finally causing the entire escalator unit 4 to move from a retracted state to an open state, forming a passage for personnel to evacuate. At the same time, by connecting the connecting platform 45 at the bottom of the escalator unit 4 with the fire ladder, the reliability of the connection between the escalator unit 4 and the fire ladder is improved, improving the safety of evacuation, helping to eliminate the fear caused by heights and speeding up the evacuation of personnel.

[0058] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
