Description

Technical Field

[0001] The present invention relates to the field of fire protection, and in particular to a fire-fighting electric smoke exhaust skylight suitable for a communication room and a use method thereof. Background Art

[0002] Fire smoke exhaust skylights are one of the important fire protection facilities in buildings. Their main function is to quickly exhaust smoke and toxic gases from the building through natural or mechanical smoke exhaust when a fire occurs, thereby ensuring the safety of people's lives.

[0003] Fire smoke exhaust skylights primarily consist of a window, control box, smoke exhaust damper, and linkage control devices. When a fire occurs in a building, the fire alarm system triggers the control box, rapidly opening the smoke exhaust damper and expelling smoke and harmful gases from the room. The window is typically made of fire-resistant material and equipped with a seal to prevent smoke from leaking through the window gaps. Once the fire is extinguished, the control box receives a signal from the fire alarm system to close the smoke exhaust damper, preventing outside air from entering the room.

[0004] After searching, an electric fire smoke exhaust skylight was disclosed, with the announcement number: CN219654102U. The feature of the skylight is that the opening fan and the opening frame are hinged, and the hinged structure is conducive to the up and down opening and closing of the opening fan. The opening or closing of the opening fan is controlled by remotely controlling the extension and retraction of the push-rod electric opening member, making it convenient to open the opening fan and avoiding manual smoke exhaust. In addition, the opening angle of the opening fan can be adjusted by adjusting the installation angle of the push-rod electric opening member, which is more conducive to the discharge of smoke and improves the safety of use.

[0005] The deficiencies of this invention are:

[0006] This invention uses an electric push rod to open and close the skylight. When the fire is large, the wires of the electric push rod or the control panel and other major communication components will be burned out, causing the electric push rod to malfunction and the skylight to be unable to open.

[0007] Secondly, the stability of electric push rods and related electronically controlled drive equipment is lower than that of mechanical drives, and the probability of failure is also higher, so it is dangerous to use them in the fire protection field.

[0008] Second, the invention does not have a relevant auxiliary smoke exhaust structure, and its smoke exhaust efficiency needs to be improved. Summary of the Invention

[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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 are within the scope of protection of the present invention.

[0057] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0058] For example 1, please refer to Figures 1 to 18 A fire-fighting electric smoke exhaust skylight suitable for a communication room, comprising a mounting plate 1 and a window provided on the mounting plate 1, wherein two symmetrically arranged window frames 2 are slidably mounted on the window, wherein a glass plate 201 is embedded in the window frame 2, and a locking portion 101 integrally formed therewith is provided on the mounting plate 1, wherein the mounting plate 1 is fixed to the top of the room via the locking portion 101, and further comprising:

[0059] An assembly groove 102 is provided at the bottom of the mounting plate 1 and a smoke exhaust mechanism is installed in the assembly groove 102;

[0060] Two mounting slots 103, the two mounting slots 103 are opened on both sides of the assembly slot 102, and the electric telescopic rods 7 are fixed in the two mounting slots 103. The two electric telescopic rods 7 are arranged opposite to each other. Two rack plates 203 are relatively slidably installed in the assembly slot 102. The two rack plates 203 are respectively fixedly connected to the two window frames 2, and the two rack plates 203 are also connected to the movable rods of the two electric telescopic rods 7 through a detachable component; wherein, there are four rack plates 203, which are respectively located on both sides of the window, two on each side;

[0061] A guide rod 6 is fixed on the opposite side of the two rack plates 203 , and a No. 2 spring 601 is installed in the guide rod 6 . The end of the guide rod 6 away from the rack plate 203 is fixed to the assembly groove 102 .

[0062] In an embodiment of the present invention, when a fire occurs in a machine room, in order to prevent excessive smoke from accumulating inside, the smoke is discharged through the skylight, and the implementation method is as follows:

[0063] The two electric telescopic rods 7 are both connected to the smoke alarm in the machine room. When the smoke alarm is triggered, the two electric telescopic rods 7 are driven to work. When the electric telescopic rods 7 are working, the movement of the movable rod drives the two window frames 2 to move in opposite directions, so as to open the window, allowing the smoke to be discharged from the machine room through the window.

[0064] When the fire is large, the electric telescopic rod 7 may malfunction due to excessive temperature. During this process, the rack plate 203 is disconnected from the electric telescopic rod 7 by the disengagement assembly. When the rack plate 203 is disconnected from the electric telescopic rod 7, the elastic potential energy stored in the guide rod 6 drives the two rack plates 203 and the window frame 2 to move in opposite directions, thereby releasing the blockage of the window.

[0065] Furthermore, whether the elastic potential energy of the guide rod 6 is released to drive the two window frames 2 to slide in opposite directions, or the electric telescopic rod 7 is used to push the two window frames 2 to slide in opposite directions to drive the smoke exhaust mechanism to work, the smoke in the machine room is discharged to the outside through the smoke exhaust mechanism.

[0066] Embodiment 2 is distinguished from Embodiment 1 in that: the smoke exhaust mechanism includes two No. 2 smoke exhaust fans 5 , the two No. 2 smoke exhaust fans 5 are relatively slidably mounted in the assembly groove 102 , and the two No. 2 smoke exhaust fans 5 are connected to the rack plate 203 via a transmission assembly;

[0067] A No. 1 smoke exhaust fan 4 is provided on the opposite side of the two No. 2 smoke exhaust fans 5. The two No. 1 smoke exhaust fans 4 are rotatably installed in the assembly groove 102 through a connecting piece 401. The rotating shaft 402 of the No. 1 smoke exhaust fan 4 is extended. A locking assembly that cooperates with the rotating shaft 402 is installed on the connecting piece 401, and the locking assembly is also connected to the No. 2 smoke exhaust fan 5.

[0068] Reinforcements are provided on opposite sides of the two No. 2 smoke exhaust fans 5 .

[0069] In the embodiment of the present invention, when the two rack plates 203 move in opposite directions, the two second smoke exhaust fans 5 are driven to move relative to each other through the transmission assembly, thereby achieving the goal that when the two window frames 2 move in opposite directions to release the blockage of the window, the two second smoke exhaust fans 5 stop at the window;

[0070] Among them, when the two second smoke exhaust fans 5 move relative to each other to the end of the stroke, the two second smoke exhaust fans 5 are reinforced by the reinforcement component to ensure their stability during operation;

[0071] Secondly, when the two second exhaust fans 5 move relative to each other, the limit of the locking assembly is released to allow the first exhaust fan 4 to flip to an upright state;

[0072] When the No. 1 smoke exhaust fan 4 is working, the smoke in the machine room will be transported toward the window. When the No. 2 smoke exhaust fan 5 is working, the smoke will be discharged out of the machine room. In the event of a fire, the smoke generated will gather on the roof. By adopting this embodiment of the present invention, the smoke can be discharged quickly.

[0073] The transmission assembly includes two gears 9 rotatably mounted on both sides of the second smoke exhaust fan 5 . The two gears 9 are engaged with the rack portions 501 provided on both sides of the second smoke exhaust fan 5 . The gears 9 also cooperate with the rack plate 203 .

[0074] In an embodiment of the present invention, when the two window frames 2 move in opposite directions, they also drive the rack plate 203 to follow the movement. When the rack plate 203 moves, it drives the gear 9 to rotate by engaging with the gear 9. When the gear 9 rotates, it drives the No. 2 smoke exhaust fan 5 to move relative to the rack plate 203 by engaging with the rack portion 501, thereby achieving that when the window frames 2 slide in opposite directions to release the seal on the window, the two No. 2 smoke exhaust fans 5 move to directly below the window.

[0075] The reinforcement member includes a trigger plate 505 fixed to one side of the second smoke exhaust fan 5, and a passage slot 504 for the trigger plate 505 to pass through is opened on the side of the other second smoke exhaust fan 5 facing the trigger plate 505, and a trigger switch 503 cooperating with the trigger plate 505 is also installed in the second smoke exhaust fan 5;

[0076] The trigger switch 503 is connected to the second smoke exhaust fan 5 and the first smoke exhaust fan 4 via a wire.

[0077] In the embodiment of the present invention, the second smoke exhaust fan 5 is slidably connected to the slide rail provided in the assembly groove 102 via a slider at the bottom to achieve guided sliding of the second smoke exhaust fan 5. Since only the sliders at the side ends of the two second smoke exhaust fans 5 are in the slide rail when they slide relative to each other, the majority of the sliders are suspended in the air, making the second smoke exhaust fan 5 relatively unstable when working.

[0078] The solution of this embodiment is that when the two second smoke exhaust fans 5 move relative to each other, one of the second smoke exhaust fans 5 drives the trigger plate 505 to follow the movement. As the two trigger plates 505 move relative to each other, the trigger plate 505 is inserted into the through slot 504. The groove 504 and the trigger plate 505 cooperate to reinforce the two second smoke exhaust fans 5, so that the two second smoke exhaust fans 5 are more stable when following each other.

[0079] Secondly, when the trigger plate 505 is fully inserted into the through slot 504, the trigger switch 503 is squeezed to trigger the switch 503, and the second smoke exhaust fan 5 and the first smoke exhaust fan 4 are driven to work simultaneously through the trigger switch 503;

[0080] The second smoke exhaust fan 5 is further provided with a plurality of through slots 502 , which are used to increase the passage of wind and smoke.

[0081] The locking assembly includes a locking rod 8 fixed on the opposite side of the two No. 2 smoke exhaust fans 5, a locking hole 403 is opened on the rotating shaft 402 of the No. 1 smoke exhaust fan 4, and the locking rod 8 is inserted into the locking hole 403. A pin 404 is slidably installed on the connecting member 401, and the pin 404 is perpendicular to the rotating shaft 402. A sleeve 406 fixed to the connecting member 401 is sleeved on the pin 404, and a No. 1 spring 405 is fixed in the sleeve 406, and the other end of the No. 1 spring 405 is fixed to the pin 404.

[0082] In the embodiment of the present invention, when the two second smoke exhaust fans 5 move relative to each other, the locking rod 8 is driven to follow the movement. When the locking rod 8 moves, it is pulled out from the locking hole 403 to release the limit on the rotating shaft 402. The first smoke exhaust fan 4 and the rotating shaft 402 are limited by the locking rod 8, so that the locking rod 8 remains in a parallel state. When the locking rod 8 is pulled out, the first smoke exhaust fan 4 is flipped around the rotating shaft 402 due to its own weight, so that it rotates to an upright state.

[0083] When the smoke exhaust fan 4 is turned over to the vertical state, the smoke exhaust fan 4 will generate a certain thrust when it is working, thereby causing the smoke exhaust fan 4 to be tilted, thereby causing the direction of the smoke exhaust fan 4 to be tilted, resulting in reduced efficiency of smoke transportation. The solution provided by the present invention is that when the smoke exhaust fan 4 is turned over, the rotating shaft 402 will be driven to rotate accordingly, so that the locking hole 403 is rotated from the horizontal state to the vertical state. When the locking hole 403 is rotated to the vertical state, the locking hole 403 coincides with the sleeve 406, and the elastic potential energy of the No. 1 spring 405 is released to drive the pin 404 to be inserted into the locking hole 403, so as to lock the rotating shaft 402 through the pin 404, so that the smoke exhaust fan 4 will not turn over and change the wind direction due to the thrust generated when the smoke exhaust fan 4 is working;

[0084] In this embodiment, the locking of the No. 1 smoke exhaust fan 4 and the rotating shaft 402 is a single-use structure.

[0085] The four sides of the window frame 2 are all provided with arc-shaped parts 202 , and the arc-shaped parts 202 can reduce the wind noise on the top of the machine room.

[0086] Embodiment 3 is distinguished from Embodiment 1 and / or Embodiment 2 in that: the disengagement assembly includes a transmission member 701 slidably mounted in the mounting groove 103 , the transmission member 701 is fixed to the rack plate 203 , and the transmission member 701 has a rectangular groove formed on a side facing the electric telescopic rod 7 ;

[0087] A connecting block 702 is fixed to one end of the movable rod of the electric telescopic rod 7 facing the transmission member 701, and a U-shaped piece is provided on the side of the connecting block 702 away from the electric telescopic rod 7, and the U-shaped piece is embedded in the rectangular groove;

[0088] The transmission member 701 and the U-shaped member are both provided with a movable groove 704 , in which two symmetrically arranged limiting plates 705 are slidably installed, and a pushing member is installed between the two limiting plates 705 .

[0089] See also Figures 11-18 In the embodiment of the present invention, under normal conditions, the relative / opposite movement of the two window frames 2 is achieved by the operation of the electric telescopic rod 7, which drives the transmission member 701 and the rack plate 203. The main synchronous movement is achieved by limiting the position of the limit plate 705. When the movable rod of the electric telescopic rod 7 moves, it drives the connecting block 702 to follow the movement. When the connecting block 702 moves, it is limited by the limit plate 705 located in the U-shaped member of the connecting block 702 and the movable groove 704 of the transmission member 701, so that the connecting block 702 drives the transmission member 701 to follow the movement when it moves. The movement of the transmission member 701 drives the rack plate 203 to move.

[0090] Among them, when the fire is large or other reasons cause the electric telescopic rod 7 to malfunction, the pushing member physically senses the temperature change. When the temperature reaches a certain level, the two limiting plates 705 are pushed in opposite directions to release the limit of the U-shaped member of the connecting block 702, so that the transmission member 701 is separated from the connecting block 702. At the moment of separation, the elastic potential energy of the second spring 601 is released to drive the two rack plates 203 and the window frame 2 to move in opposite directions to open the window;

[0091] Among them, using this method to drive the two window frames 2 to move in opposite directions still triggers the normal operation of the smoke exhaust mechanism. When the two window frames 2 are in abutment, that is, when they are below the window, the second spring 601 is in a pulled state and reserves a certain amount of elastic potential energy.

[0092] The original intention of the design of this embodiment is that the existing fire skylights are driven by electronic devices such as electric push rods or steering gears. Of course, this method is more convenient to use and is relatively simple to operate and install. However, this method has a more serious problem;

[0093] When a fire occurs in the computer room, since electronic equipment needs to transmit data through wires to control the driving equipment to open the skylight, if the fire is large, it is very easy to burn the wires and related control units, causing the electronic driving equipment to malfunction. When this problem occurs, the skylight cannot be opened normally. The method provided in this embodiment is to automatically open the skylight in an emergency when such a problem occurs, without the help of electronic driving equipment, because metal mechanical drive has inherent advantages in this regard, and is more stable and can tolerate higher stability.

[0094] The pushing member includes a heat conducting member 703, and the heat conducting member 703 includes multiple memory metal sheet groups 706. The multiple memory metal sheet groups 706 are fixed by a fixing plate, and the fixing plate is installed between two limiting plates 705. A heat conducting block is fixed on the fixing plate, and the memory metal sheet group 706 is in sliding contact with the heat conducting block.

[0095] In an embodiment of the present invention, when a fire occurs and the electric telescopic rod 7 cannot work normally, as time goes by, the temperature in the room will gradually converge toward the roof. The heat conductive block is a heat conductive component, and the heat is transferred to the memory metal sheet group 706 through the heat conductive block. The memory metal sheet group 706 will gradually deform toward the initial state due to the increase in temperature, that is, from a curved shape to a straight shape. This deformation will increase the straight length of the memory metal sheet group 706, thereby pushing the two limit plates 705 to move in opposite directions.

[0096] Two baffles 3 are fixed at the bottom of the mounting plate 1 at the position of the assembly groove 102 , and an embedded plate 301 is clamped on each of the two baffles 3 .

[0097] In the embodiment of the present invention, the baffle 3 can protect the components in the assembly groove 102 to prevent the components from being exposed;

[0098] Secondly, the embedded plate 301 is snap-on, which means that the embedded plate 301 is detachably arranged on the baffle 3. When the embedded plate 301 is subjected to force, it falls off, and then drives the embedded plate 301 to fall when the No. 1 exhaust fan 4 flips over, preventing the embedded plate 301 from blocking the No. 1 exhaust fan 4 from flipping over.

[0099] The present invention also provides a method for using a fire-fighting electric smoke exhaust skylight suitable for a communication room, which comprises the following steps:

[0100] Step 1: Under normal circumstances, the electric telescopic rod 7 drives the two window frames 2 to move in opposite directions to unblock the skylight, and at the same time drives the smoke exhaust mechanism to work;

[0101] Step 2: When the smoke exhaust mechanism is working, increase the speed of air flowing from the machine room to the outside to increase the smoke exhaust efficiency;

[0102] Step three, when the electric telescopic rod 7 fails to work normally, the connection between the electric telescopic rod 7 and the rack plate 203 and the window frame 2 is released by disengaging the assembly, so as to release the elastic potential energy of the No. 2 spring 601 to drive the rack plate 203 and the window frame 2 to move in opposite directions, so as to release the blockage of the window in an emergency, and the smoke exhaust mechanism is still triggered during the process of unsealing.

[0103] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
