Description

Technical Field

[0001] The invention relates to the technical field of smoke exhaust windows in high-rise buildings, and in particular to a manual opening and closing mechanism for facilitating opening all smoke exhaust windows at one time. Background Art

[0002] At present, with the rapid development of my country's construction industry, fire prevention and smoke exhaust in high-rise buildings has become one of the most important measures to protect high-rise buildings. In particular, windows that exhaust smoke in a natural way should be installed in the smoke-proof staircase antechamber, fire elevator antechamber and shared antechamber on the outer edge of high-rise buildings. According to the national "Code for Fire Protection Design of Buildings" GB0016-2014, the area of ​​effective smoke exhaust ports of windows in corridors and rooms shall not be less than 2% of the area of ​​the place. At the same time, it is stipulated that natural smoke exhaust windows should be set on the ceiling or above the outer wall. When set on the outer wall, the height of the lower edge of the natural smoke exhaust window (the starting point for calculating the effective natural window opening area) from the indoor floor should not be lower than the height H (H = 1.6m + 0.1 * clear height) of the lower edge of the smoke storage bin (or smoke barrier vertical wall); for corridors or areas with a clear height of no more than 3m, the height of the lower edge of the natural smoke exhaust window from the indoor floor should not be less than 1 / 2 of its clear height; natural smoke exhaust windows should be opened along the airflow direction of fire smoke and have a device for convenient opening. The window opening area that does not meet the above requirements should not be counted into the effective natural window opening area. There are also corresponding requirements for the installation of natural ventilation windows in stairwells, antechambers, and shared antechambers.

[0003] In fact, the majority of people who die in fires are not burned to death, but suffocated or choked by thick smoke. It is difficult for air to circulate in the fire, the high-temperature smoke cannot be discharged, and the oxygen in the fire is exhausted. Multiple reasons lead to the death of people in the fire. Therefore, when a fire occurs, it is very important to open all smoke exhaust windows in time.

[0004] Due to historical reasons, the natural lighting and smoke exhaust windows in my country's current buildings are generally set up in the old-fashioned style, which is completely opened manually. If a fire occurs in a window of ordinary height, people's first reaction is to escape, and no one will think of opening the window. As for high-position windows, no one cares about opening the window, because there are many smoke exhaust windows, and they are located at the top of the wall, and people standing on the ground may not be able to reach them directly, so it is inconvenient to open the window. Therefore, the transformation of the old-fashioned smoke exhaust windows is imminent. Summary of the invention

The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0105] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0106] Embodiment 1:

[0107] like Figure 1As shown, a multifunctional fire smoke exhaust window comprises at least one smoke exhaust window, including a window frame 2 and a window sash 3, wherein the window sash 3 is movably mounted in the window frame 2; a wall 1, wherein the smoke exhaust window is mounted on the wall 1; a control bus 6, wherein the control bus 6 is mounted on the wall 1; a first counterweight block 7, wherein the first counterweight block 7 is mounted at one end of the control bus 6, wherein the first counterweight block 7 is at least one, and wherein the first counterweight block 7 is suspended on the control bus 6; a closing mechanism 4, wherein the closing mechanism 4 is mounted between the window sash 3 and the window frame 2, wherein the window sash 3 is connected to the wall 1; and a closing mechanism 4 is mounted between the window sash 3 and the window frame 2. The window sash 3 is automatically opened after the closing mechanism 4 is opened; a connecting line 5, the closing mechanism 4 is connected to the control bus 6 through the connecting line 5, and the connecting line 5 controls the opening of the closing mechanism 4 under the drive of the control bus 6; a multi-function controller, the multi-function controller is arranged at the other end of the control bus 6, and includes a manual positioner 18; a temperature control mechanism 19; an electromagnetic control mechanism 20, the manual positioner 18, the temperature control mechanism 19 and the electromagnetic control mechanism 20 can independently control the tension and relaxation of the control bus 6; Figure 3 As shown, when the control bus 6 is relaxed under the control of the manual positioner 18, the temperature control mechanism 19 or the electromagnetic control mechanism 20, the first counterweight block 7 falls under the action of gravity, and the control bus 6 moves toward the first counterweight block 7 under the pull of the first counterweight block 7, driving the connecting line 5, and the connecting line 5 controls the closing mechanism 4 to open, thereby opening the window sash 3.

[0108] Embodiment 2:

[0109] like Figure 1 , Figure 5 and Figure 6As shown, on the basis of Example 1, as a preference, the closing mechanism 4 includes a socket 4.6, which is installed on the window sash 3; a latch, which is installed on the window frame 2, and the latch includes a latch tongue 4.5; a connecting rod 4.1, one side of the connecting rod 4.1 is connected to the latch tongue 4.5, and the other side is connected to the connecting line 5; an open pin 4.2, which is arranged on the connecting rod 4.1, and a latch spring 4.4 is mounted on the connecting rod 4.1 between the open pin 4.2 and the latch tongue 4.5; a latch seat 4.3, the connecting rod 4.1 equipped with the latch spring 4.4 is arranged in the latch seat 4.3, and the latch seat 4.3 has openings on both sides, and the maximum diameter of the opening on the side away from the latch tongue 4.5 is smaller than the length of the open pin 4.2, and the opening on the side close to the latch tongue 4.5 can make the latch tongue 4.5 retract into the latch seat 4.3. When the multi-function controller releases the control bus 6, the control bus 6 moves to the left driven by the first counterweight 7, pulling the connecting line 5, and the connecting line 5 pulls the connecting rod 4.1, so that the latch tongue 4.5 leaves the socket 4.6 on the window sash 3 and retracts into the latch seat 4.3. The window sash 3 is no longer controlled by the closing mechanism 4 and opens. At this time, the latch tongue 4.5 is also subject to the elastic force of a latch spring 4.4 and tends to pop out. When the control bus 6 is restored, the connecting line 5 is relaxed, and the latch tongue 4.5 pops out under the elastic force of the latch spring 4.4, so that the window sash 3 can be closed.

[0110] Embodiment 3:

[0111] like Figure 1 As shown, on the basis of Example 1 or Example 2, the closing mechanism 4 further includes a latch extension fixing plate 4.7, which is mounted on the window frame 2, and the latch is mounted on the latch extension fixing plate 4.7. In many cases, the width of the window sash 3 is not as wide as the window frame 2, so the window sash 3 is arranged in the middle of the window frame 2, and the inner side of the window sash 3 is not flush with the inner side of the window frame 2, so it is necessary to add a latch extension fixing plate 4.7, which is mounted on the inner side of the window frame 2 and extends downward or toward the inner side of the window frame 2, so that the latch mounted on the latch extension fixing plate 4.7 can be flush with the insertion hole 4.6.

[0112] Embodiment 4:

[0113] like Figure 2As shown, based on Example 1 or Example 2, the inner side surfaces of some window sashes 3 are flush with the inner side surfaces of the window frame 2, so in many cases the closing mechanism 4 of such a smoke exhaust window is installed in an up-down direction, but the control bus 6 of the present invention moves in the left-right direction, so a fixed pulley 12 is installed on the upper side of the closing mechanism 4 on the wall 1, and the connecting wire 5 bypasses the fixed pulley 12 and is connected to the control bus 6. The pulling direction of the connecting wire 5 is changed by the fixed pulley 6. When the connecting wire 5 is pulled to the left by the control bus 6, the connecting rod 4.1 is pulled vertically to make the latch tongue 4.5 leave the socket 4.6 on the window sash 3 and retract into the latch seat 4.3, and the window sash 3 is no longer controlled by the closing mechanism 4 and is opened.

[0114] Embodiment 5:

[0115] like Figure 3 and Figure 4 As shown, in order to facilitate the automatic opening of the window sash 3 after the closing mechanism 4 is opened, a window opening counterweight mechanism 17 is installed on the upper half of the window sash 3. When the closing mechanism 4 is opened, the window opening counterweight mechanism 17 drives the window sash 3 to open outwards under the gravity of the window opening counterweight mechanism 17.

[0116] Embodiment 6:

[0117] like Figure 4 As shown, on the basis of Example 5, a bracket 16 is provided on the upper half of the window sash 3, and the window opening counterweight mechanism 17 is installed on the bracket 16, so that the overall center of gravity of the window opening counterweight mechanism 17 and the window sash 3 is offset outward, which is more conducive to the window sash 3 opening outward after the closing mechanism 4 is opened.

[0118] Embodiment 7:

[0119] like Figure 4 As shown, on the basis of Example 5, in order to prevent the window sash 3 from having too large an impact force when opening outward, a counterweight connecting rod 17.1, a second counterweight block 17.2 and a buffer spring 17.3 are arranged on the window opening counterweight mechanism 17, wherein the counterweight connecting rod 17.1 passes through the bracket 16 from top to bottom for installation; the second counterweight block 17.2 is at least one, and the second counterweight block 17.2 is fixedly mounted on the counterweight connecting rod 17.1 on the lower side of the bracket 16; and the buffer spring 17.3 is sleeved on the counterweight connecting rod 17.1 on the upper side of the bracket 16. After the closing mechanism 4 is opened, the window sash 3 opens outward under the gravity of the second counterweight block 17.2. When the window sash 3 is opened to a specified angle and no longer opens outward, the instantaneous impact force is relatively large, and the buffer spring 17.3 can reduce this impact force and extend the service life of the window sash 3.

[0120] Embodiment 8:

[0121] like Figure 3As shown, on the basis of the aforementioned embodiment, a damping connector 15 is further installed between the window frame 2 and the window sash 3. The damping connector 15 is preferably a hydraulic damper. The hydraulic damper is used here to slow down the speed at which the window sash 3 opens outwards and plays a role in shock absorption, thereby further extending the service life of the window sash 3.

[0122] Embodiment 9:

[0123] like Figure 7 and Figure 8 As shown, the manual positioner 18 includes a base 18.1, which is installed on the wall 1; a handle 18.2, which is installed on the base 18.1 and connected to the control bus 6; and a limit seat 18.3, in which the handle 18.2 is stuck. In combination with Example 1, in this embodiment, the handle 18.2 can be fixed to the limit seat 18.3 by various means such as a mechanical lock and an electronic lock. When a fire occurs, the handle 18.2 is unlocked and pushed upward, the control bus 6 is loosened, and the first counterweight block 7 falls downward under the action of gravity, driving the loose control bus 6 to move to the left, and pulling the connecting line 5 to move to the left, as shown in FIG. Figure 5 and Figure 6 As shown, the connecting wire 5 pulls the connecting rod 4.1 to drive the latch tongue 4.5 to retract from the insertion hole 4.6 into the latch seat 4.3. At this time, the latch tongue 4.5 retracts into the latch seat 4.3 and has a tendency to pop outward under the action of the spring 4.4. The window sash 3 and the window frame 2 are no longer constrained by the closing mechanism 4. Figure 3 As shown, the window sash 3 is opened outwards under the drive of the window opening counterweight mechanism 17 .

[0124] Embodiment 10:

[0125] like Fig. 9 As shown, the manual positioner 18 is composed of a hand-cranked winch cylinder 18.4, a ratchet 18.5 and a winch cylinder handle 18.6. The control bus 6 is rolled up and mounted on the hand-cranked winch cylinder 18.6; the ratchet 18.5 is coaxially connected to the hand-cranked winch cylinder 18.6, and a limiting device is arranged on the outer side of the ratchet 18.5; the winch cylinder handle 18.4 is coaxial with the hand-cranked winch cylinder 18.6. In combination with Example 1, when there is no fire, the ratchet 18.5 is stuck by the limiting device, and the control bus 6 is tightened by the first counterweight 7. When an emergency fire occurs, the ratchet 18.5 is released, and the winch cylinder handle 18.6 is shaken, so that the control bus 6 is relaxed and moves to the left under the action of the first counterweight 7, so that the connecting line 5 pulls the connecting rod 4.1 to drive the latch tongue 4.5 to retract from the socket 4.6 into the latch seat 4.3, and the window sash 3 and the window frame 2 are no longer constrained by the closing mechanism 4, as shown in FIG.

[0151] Embodiment 21:

The temperature control mechanism 19 is not fixedly installed on the wall 1. Another section of the control bus 6 is connected to the lower end of the first outer shell 19.1 of the temperature control mechanism 19, and passes through a fixed pulley 12 fixed to the wall 1 downward, passes through the movable pulley 20.6 at the lower end of the electromagnetic control mechanism 20 upward, and then is connected to the manual positioner 18 downward.

[0153] Once a fire occurs, someone on the scene discovers it in time. When the manual control method is adopted, the manual positioner 18 is activated. Its working principle has been explained in Examples 9 and 10 and will not be repeated here. The control bus 6 connected to the manual positioner 18 is relaxed, and the control bus 6 bypasses the movable pulley 20.6 and the fixed pulley 12. Under the action of the first counterweight block 7, it slides together with the temperature control mechanism 19 that is not installed on the wall 1, driving the connecting line 5 to open the closing mechanism 4, so that the window sash 3 is opened.

[0154] Once a fire occurs, the monitoring personnel remotely discover the fire on site through the monitoring probe, press the control switch while the alarm is sounded, and start the electromagnetic control mechanism 20. The electromagnetic control mechanism 20 is in action. Its working principle has been explained in Example 16 and Example 17 and will not be repeated here. The movable pulley 20.6 slides downward, so that the control bus 6 wrapped around the movable pulley 20.6 is loosened. The control bus 6 drives the temperature control mechanism 19 to slide together under the action of the first counterweight block 7, and drives the connecting line 5 to open the closing mechanism 4, so that the window sash 3 is opened.

[0155] Once a fire occurs and no one finds it on the scene, and the monitoring personnel are not on duty for various reasons, when the temperature on the scene reaches the set temperature, the temperature control mechanism 19 is activated, and its working principle has been described in Examples 11 to 15, and will not be repeated here. The first connecting rod 19.3 is no longer restricted by the first movable block 19.2 and can slide up and down. The control bus 6 and the first connecting rod 19.3 slide together under the gravity of the first counterweight block 7, driving the connecting line 5 to open the closing mechanism 4, so that the window sash 3 is opened. At this time, the control bus 6 connected to the lower end of the first outer shell 19.1 is still in a tight state because the manual positioner 18 and the electromagnetic control mechanism 20 are not in action, but the window sash 3 can still be opened.

[0156] like Figure 3 As shown, when the control bus 6 is relaxed under the control of the manual positioner 18, the temperature control mechanism 19 or the electromagnetic control mechanism 20, the first counterweight block 7 falls under the action of gravity, and the control bus 6 moves toward the first counterweight block 7 under the pull of the first counterweight block 7, driving the connecting line 5, and the connecting line 5 controls the closing mechanism 4 to open, thereby opening the window sash 3.

When the multi-function controller does not release the control bus 6, the control bus 6 is taut, tightening the elastic mechanism, and the elastic mechanism has a tendency to retract, so that the control bus 6 tends to move toward the elastic mechanism.

[0159] like Figure 1 As shown, the multifunctional controller is arranged at the other end of the control bus 6, and includes a temperature control mechanism 19, an electromagnetic control mechanism 20 and a manual positioner 18 connected in sequence, and the electromagnetic control mechanism 20 and the manual positioner 18 are fixedly mounted on the wall 1, and the manual positioner 18, the temperature control mechanism 19 and the electromagnetic control mechanism 20 can independently control the tension and relaxation of the control bus 6; Fig.10 and Fig.11 As shown, the control bus 6 is connected to the upper end of the first connecting rod 19.3 of the temperature control mechanism 19 from the smoke exhaust window side. The temperature control mechanism 19 is not fixedly installed on the wall 1. Another section of the control bus 6 is connected to the lower end of the first outer shell 19.1 of the temperature control mechanism 19, and passes through a fixed pulley 12 fixed to the wall 1 downward, passes through the movable pulley 20.6 at the lower end of the electromagnetic control mechanism 20 upward, and then is connected to the manual positioner 18 downward.

[0160] Once a fire occurs, someone on the scene discovers it in time. When the manual control method is adopted, the manual positioner 18 is activated. Its working principle has been explained in Examples 9 and 10 and will not be repeated here. The control bus 6 connected to the manual positioner 18 is relaxed, and the control bus 6 bypasses the movable pulley 20.6 and the fixed pulley 12. Under the elastic force of the elastic mechanism, it slides together with the temperature control mechanism 19 that is not installed on the wall 1, driving the connecting line 5 to open the closing mechanism 4, so that the window sash 3 is opened.

[0161] Once a fire occurs, the monitoring personnel remotely discover the fire on site through the monitoring probe, press the control switch while the alarm is sounded, and start the electromagnetic control mechanism 20. The electromagnetic control mechanism 20 is in action. Its working principle has been explained in Example 16 and Example 17 and will not be repeated here. The movable pulley 20.6 slides downward, so that the control bus 6 wrapped around the movable pulley 20.6 is loosened. The control bus 6 drives the temperature control mechanism 19 to slide together under the elastic force of the elastic mechanism, and drives the connecting line 5 to open the closing mechanism 4, so that the window sash 3 is opened.

[0162] Once a fire occurs and no one finds it on the scene, and the monitoring personnel are not on duty for various reasons, when the temperature on the scene reaches the set temperature, the temperature control mechanism 19 is activated, and its working principle has been described in Examples 11 to 15, and will not be repeated here. The first connecting rod 19.3 is no longer restricted by the first movable block 19.2 and can slide up and down. The control bus 6 and the first connecting rod 19.3 slide together under the elastic force of the elastic mechanism, driving the connecting line 5 to open the closing mechanism 4, so that the window sash 3 is opened. At this time, the control bus 6 connected to the lower end of the first outer shell 19.1 is still in a tight state because the manual positioner 18 and the electromagnetic control mechanism 20 are not in action, but the window sash 3 can still be opened.

[0163] like Figure 3 As shown, when the control bus 6 is relaxed under the control of the manual positioner 18, the temperature control mechanism 19 or the electromagnetic control mechanism 20, the first counterweight block 7 falls under the action of gravity, and the control bus 6 moves toward the first counterweight block 7 under the pull of the first counterweight block 7, driving the connecting line 5, and the connecting line 5 controls the closing mechanism 4 to open, thereby opening the window sash 3.
