Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to an automatic smoke exhaust window for fire protection engineering. Background Technology

[0002] Fire protection engineering refers to the technical and management activities carried out to prevent and control fires, protect people's lives and safety, and reduce property damage. It covers many aspects, including but not limited to fire prevention, fire alarm, fire extinguishing system design, fire equipment installation and maintenance, fire safety assessment, and emergency rescue plan development.

[0003] However, most traditional smoke exhaust windows require manual opening or closing and cannot be automatically opened or discharged as needed, which makes them inconvenient to use.

[0004] Therefore, those skilled in the art have provided an automatic smoke exhaust window for fire protection engineering to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic smoke exhaust window for fire protection engineering. Compared to most traditional smoke exhaust windows, this smoke exhaust window is equipped with a limit strip and a window frame. When other fire-fighting equipment is activated, the second electric telescopic rod of the smoke exhaust window, under the action of the control module, pushes the limit strip, causing the limit block to disengage from the window frame. At this time, the first spring releases its elastic force to push the limit slider, thereby causing the connecting rod to control the push rod to push the window frame away from the window frame. This allows the smoke exhaust window to open automatically in the event of a fire, reducing delays caused by manual operation and ensuring that measures are taken in the first instance. This improves the safety of the smoke exhaust window.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic smoke exhaust window for fire protection engineering includes a window frame. A smoke exhaust mechanism is provided on the upper surface of the window frame. The smoke exhaust mechanism includes a housing. A limiting groove is formed inside one side of the housing. A first electric telescopic rod is fixedly connected to the center of the bottom surface of the limiting groove. A push plate is fixedly connected to the output end of the first electric telescopic rod. A rack is fixedly connected to the outer walls on both sides of the push plate. A ventilation groove is formed in the middle of the front outer wall of the housing. An exhaust fan is fixedly connected to the middle of the inner wall of the ventilation groove. Multiple rotating rods are rotatably connected to the front and rear ends of the inner wall of the ventilation groove. A gear is fixedly connected to the outer wall on one side of each rotating rod.

[0008] A window opening mechanism is provided in the middle of the inner wall of the window frame. The window opening mechanism includes a fixing frame, a counterweight, a limiting slot, and a storage slot. Limiting slots are provided on both sides of the outer wall of the front end of the fixing frame. A first spring is fixedly connected to the inner top surface of the limiting slot. A limiting slider is fixedly connected to the lower surface of the first spring. A connecting rod is hinged to the front and rear ends of the lower surface of the limiting slider. A push rod is hinged to the end of the connecting rod away from the limiting slider. A second electric telescopic rod is fixedly connected to the middle of the inner wall of one side of the storage slot. A limiting strip is fixedly connected to the output end of the second electric telescopic rod. Multiple second springs are fixedly connected to the outer wall of the limiting strip away from the second electric telescopic rod. Limiting blocks are fixedly connected to the front and rear ends of the outer wall of the limiting strip.

[0009] The front and rear ends of the inner wall of the window frame are hinged to window frames, and a control module is fixedly connected to the center of the upper end of the window frame.

[0010] Compared with most traditional smoke exhaust windows, this fire-fighting smoke exhaust window is equipped with a smoke exhaust mechanism. When the window opening mechanism is activated, the first electric telescopic rod and the exhaust fan will start simultaneously. The first electric telescopic rod opens the closed guide vanes through gear meshing, so that the exhaust fan can automatically extract and discharge smoke and dust, thereby further improving the safety of the smoke exhaust window.

[0011] Furthermore, the outer shell is fixedly connected to the upper surface of the window frame, and a guide vane is fixedly connected to the middle of the outer wall of the rotating rod;

[0012] Through the above technical solution, the smoke exhaust window can automatically discharge smoke and dust, and the guide vanes can protect the exhaust fan when the smoke exhaust mechanism is not in use.

[0013] Furthermore, the gear meshes with the rack;

[0014] The above technical solution enables the first electric telescopic rod to rotate by controlling the rotating rod, thereby opening or closing the guide vane.

[0015] Furthermore, the fixing frame is fixedly connected to the center of the inner wall of the window frame, and the counterweights are fixedly connected to the outer walls on both sides of the window frame respectively;

[0016] The above technical solutions can accelerate the opening speed of the window frame, thereby improving the efficiency of the smoke exhaust window.

[0017] Furthermore, the limiting slots are respectively opened at the upper ends of the outer walls on both sides of the window frame, and the limiting slots are engaged with the limiting blocks.

[0018] The above technical solution enables the limiting block to lock the position of the window frame on the window frame.

[0019] Furthermore, the storage slots are respectively opened on both sides inside the upper end of the window frame, and the limiting strip slides inside the storage slots;

[0020] Through the above technical solution, the second electric telescopic rod can be controlled to move the limiting strip smoothly inside the storage slot.

[0021] Furthermore, the limiting slider slides inside the limiting groove, and the end of the push rod away from the connecting rod is hinged to the limiting groove;

[0022] The above technical solution enables the limiting slider to push the push rod outward through the connecting rod.

[0023] Furthermore, a window is hinged to the inner wall of the window frame, and a handle is fixedly connected to one side of the outer wall at the front end of the window;

[0024] The above technical solution enables the smoke exhaust window to be opened under normal circumstances.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1-5 One embodiment provided by this utility model:

[0040] An automatic smoke exhaust window for fire protection engineering includes a window frame 1. A smoke exhaust mechanism 2 is provided on the upper surface of the window frame 1. The smoke exhaust mechanism 2 includes a housing 201. A limiting groove 202 is formed inside one side of the housing 201. A first electric telescopic rod 203 is fixedly connected to the center of the bottom surface of the limiting groove 202. A push plate 204 is fixedly connected to the output end of the first electric telescopic rod 203. Racks 205 are fixedly connected to the outer walls on both sides of the push plate 204. A ventilation slot 206 is formed in the middle of the front outer wall of the housing 201. An exhaust fan 207 is fixedly connected to the middle of the inner wall of the ventilation slot 206. Multiple rotating rods 208 are rotatably connected to both the front and rear ends. A gear 2010 is fixedly connected to the outer wall of one side of the rotating rod 208. The outer shell 201 is fixedly connected to the upper surface of the window frame 1. A guide vane 209 is fixedly connected to the middle of the outer wall of the rotating rod 208, so that the smoke exhaust window can automatically discharge smoke and dust. The guide vane 209 can protect the exhaust fan 207 when the smoke exhaust mechanism 2 is not in use. The gear 2010 meshes with the rack 205, so that the first electric telescopic rod 203 can rotate by controlling the rotating rod 208, thereby opening or closing the guide vane 209.

[0041] A window opening mechanism 3 is provided in the middle of the inner wall of the window frame 1. The window opening mechanism 3 includes a fixing frame 301, a counterweight 307, a limiting slot 308, and a storage slot 309. Limiting slots 302 are provided on both sides of the outer wall of the front end of the fixing frame 301. A first spring 303 is fixedly connected to the inner top surface of the limiting slot 302. A limiting slider 304 is fixedly connected to the lower surface of the first spring 303. A connecting rod 305 is hinged to the front and rear ends of the lower surface of the limiting slider 304. A push rod is hinged to the end of the connecting rod 305 away from the limiting slider 304. 306, A second electric telescopic rod 3010 is fixedly connected to the middle of the inner wall of one side of the storage slot 309. A limit strip 3011 is fixedly connected to the output end of the second electric telescopic rod 3010. Multiple second springs 3012 are fixedly connected to the outer wall of the limit strip 3011 on the side away from the second electric telescopic rod 3010. Limiting blocks 3013 are fixedly connected to the front and rear ends of the outer wall of the limit strip 3011. Window frame 4 is hinged to the front and rear ends of the inner wall of the window frame 1. A control module 7 is fixedly connected to the center of the upper end of the window frame 4.

[0042] Compared to most traditional smoke exhaust windows, this smoke exhaust window is equipped with a limit strip 3011 and a window frame 4. When other fire-fighting equipment is activated, the second electric telescopic rod 3010 of the smoke exhaust window, under the action of the control module 7, pushes the limit strip 3011, causing the limit block 3013 to disengage from the window frame 4. At this time, the first spring 303 releases its elastic force to push the limit slider 304, thereby causing the connecting rod 305 to control the push rod 306 to push the window frame 4 away from the window frame 1. This allows the smoke exhaust window to open automatically in the event of a fire, reducing delays caused by manual operation and ensuring that measures are taken in the first instance. This improves the safety of the smoke exhaust window.

[0043] The fixing bracket 301 is fixedly connected to the center of the inner wall of the window frame 1. The counterweights 307 are fixedly connected to the outer walls on both sides of the window frame 4, thereby accelerating the opening speed of the window frame 4 and improving the efficiency of the smoke exhaust window. The limiting slots 308 are respectively opened at the upper ends of the outer walls on both sides of the window frame 4. The limiting slots 308 and the limiting blocks 3013 engage with each other, thereby allowing the limiting blocks 3013 to lock the position of the window frame 4 on the window frame 1. The storage slots 309 are respectively opened on both sides of the upper inner part of the window frame 1. The limiting strips 3011 are inside the storage slots 309. The second electric telescopic rod 3010 can control the limiting strip 3011 to move smoothly inside the storage groove 309. The limiting slider 304 slides inside the limiting groove 302. The end of the push rod 306 away from the connecting rod 305 is hinged to the limiting groove 302, so that the limiting slider 304 can push the push rod 306 outward through the connecting rod 305. The inner wall of the window frame 4 is hinged to the window 5. A handle 6 is fixedly connected to one side of the outer wall at the front end of the window 5, so that the smoke exhaust window can be opened under normal circumstances.

[0044] Working principle: First, the control module 7 on the smoke exhaust window is electrically connected to other fire-fighting equipment. When other fire-fighting equipment detects a fire and starts, the control module 7 simultaneously controls the first electric telescopic rod 203, the exhaust fan 207, and the second electric telescopic rod 3010 to start. Under the meshing action of the gear 2010 and the rack 205, the first electric telescopic rod 203 can open the guide vane 209 that protects the exhaust fan 207. The second electric telescopic rod 3010 pushes the limiting strip 3011, thereby causing the limiting block 3013 to leave the limiting slot 308, and thus opening the limiting lock on the window frame 4. Under the action of the first spring 303 in the contracted state, the limiting slider 304 applies pressure to the connecting rod 305, thereby allowing the push rod 306 to push the window frame 4 away from the window frame 1. The window frame 4 can be opened relatively quickly under the action of the counterweight 307, and the window 5 installed inside the window frame 4 does not affect the normal use of the smoke exhaust window.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
