Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically to a direction-adjustable fire ventilation window. Background Technology

[0002] In modern buildings, fire safety is a crucial consideration, especially in high-rise buildings, large shopping malls, factories, and other places with high population density or large amounts of flammable materials, where the installation of fire ventilation openings is particularly important. Many buildings are designed with fire ventilation openings for normal ventilation during normal times and to remove harmful gases from the room in case of fire. Traditional fire ventilation openings are often fixed in design, and their ventilation direction and volume are difficult to adjust according to actual needs, which to some extent limits their flexibility and effectiveness in practical applications. The inability to adjust according to wind direction and strength at the fire scene leads to poor ventilation and may even exacerbate the fire. Especially in high-rise buildings or complex building structures, accurate control of wind direction is crucial for fire evacuation and firefighting. Utility Model Content

[0003] The purpose of this invention is to provide a direction-adjustable fire ventilation window that can adjust the direction and ventilation volume of the ventilation window according to the wind direction and wind force, so as to effectively remove smoke and harmful gases and provide favorable conditions for personnel evacuation and rescue.

[0004] This utility model includes a window frame with a ventilation opening inside the window frame connecting the inside and outside of the wall. A mounting portion extends vertically outward from the four edges of the ventilation opening, and a telescopic window sash is mounted on the outer side of the mounting portion. The telescopic window sash includes a bottom frame fixed to the outer edge of the mounting portion and a top frame movably connected to the outer side of the bottom frame. A front sash is mounted inside the top frame. A side sash is mounted on the side of the telescopic window sash, located between the top and bottom frames. A through groove is provided around the bottom frame at the corresponding position of the side sash, penetrating both the inner and outer sides of the bottom frame. A receiving cavity extending from the outside inward is provided on the mounting portion at the corresponding position of the through groove. One end of the side sash is fixed to the inner side of the top frame and can move within the receiving cavity under the influence of the top frame.

[0005] Preferably, the side sash includes a left sash, a right sash, an upper sash, and a lower sash respectively disposed on the four sides of the telescopic window sash, and the inner frame of each side sash can pass through the through groove and can move within the receiving cavity.

[0006] Preferably, the top frame is movably connected to the outside of the bottom frame via a hydraulic cylinder, and the top frame can drive the side fan to move within the receiving cavity under the pushing force of the hydraulic cylinder.

[0007] Preferably, there are no fewer than four hydraulic cylinders, which are evenly spaced on the frame of the telescopic window sash.

[0008] Preferably, the front panel is equipped with several movable flaps, which can be opened and closed under the action of external force.

[0009] Preferably, a plurality of movable flaps are installed on the side fan, and each movable flap on the side fan can be opened and closed independently under the action of external force.

[0010] In summary, this utility model has the following beneficial effects:

[0011] 1. Through the design of the telescopic window sash, the opening and closing state of the window sash can be flexibly adjusted according to the external wind force and wind direction conditions to adapt to different ventilation needs. Especially when the wind speed is high or the wind direction is unfavorable, the ventilation effect can be optimized by adjusting the opening direction of the window sash and the opening and closing of the movable flap, so that the ventilation window can maintain good performance under various climatic conditions.

[0012] 2. When the top frame of the telescopic window sash retracts to a position where it fits against the bottom frame, the side sash retracts into the receiving cavity. This not only reduces the area occupied by the window sash but also prevents dust accumulation on the upper side sash, thus simplifying maintenance. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] The orientations mentioned in this specification refer to the orientation of the adjustable fire ventilation window of this utility model when it is working normally. They do not limit the orientation during storage and transportation, and only represent relative positional relationships, not absolute positional relationships.

[0020] like Figures 1 to 4As shown, a direction-adjustable fire ventilation window includes a window frame 1 embedded in a wall, with a ventilation opening 2 connecting the inside and outside of the wall within the window frame 1; the four edges of the ventilation opening 2 extend vertically outward to form mounting portions 3, and a telescopic window sash is installed on the outer side of the mounting portions 3; the telescopic window sash includes a bottom frame 4 fixed to the outer edge of the mounting portions 3, and a top frame 5 movably connected to the outer side of the bottom frame 4, with a front sash 6 installed within the top frame 5, the area of ​​the front sash 6 being adapted to the ventilation opening 2 and capable of covering the area of ​​the ventilation opening 2; the telescopic... A side sash 7 is installed on the side of the window sash, located between the top frame 5 and the bottom frame 4. The area of ​​the side sash 7 is adapted to the gap between the top frame 5 and the bottom frame 4. Around the bottom frame 4, corresponding to the side sash 7, there is a through groove 401 that passes through both the inner and outer sides of the bottom frame 4. On the mounting part 3, corresponding to the through groove 401, there is a receiving cavity 301 that extends from the outside to the inside. One end of the side sash 7 is fixed to the inner side of the top frame 5 and passes through the through groove 401 under the drive of the top frame 5, and moves within the receiving cavity 301.

[0021] Furthermore, the side sash 7 includes a left side sash 701, a right side sash 702, an upper side sash 703, and a lower side sash 704 respectively disposed on the four sides of the telescopic window sash; each side sash 7 includes a side sash outer frame and a movable flap 2 installed in the side sash outer frame, the side sash outer frame and the movable flap 2 form a whole, and the inner side frame of each side sash can pass through the through groove 401 and move within the receiving cavity 301; when the sealing requirements of the ventilation window are relatively high, the gap between two adjacent side sashes can be sealed with a soft cloth.

[0022] Furthermore, the top frame 5 is movably connected to the outside of the bottom frame 4 via a hydraulic cylinder 8. Under the pushing force of the hydraulic cylinder 8, the top frame 5 can drive the side sash 7 to move within the receiving cavity 301, thereby realizing the opening and closing of the telescopic window sash side. There are no fewer than four hydraulic cylinders 8, which are evenly spaced on the frame of the telescopic window sash, making the top frame 5 more evenly stressed and the structure more stable.

[0023] Furthermore, the front fan 6 is equipped with several movable flaps 1, which can open and close under the action of external force; the side fan 7 is equipped with several movable flaps 2, and each movable flap 2 on the side fan 7 can open and close independently under the action of external force; at the same time, different ventilation volumes can be achieved by controlling the opening and closing angles of the movable flaps on the front fan 6 and the side fan 7. This part is existing technology and will not be described in detail here.

[0024] When in use, if the outside wind is weak or the wind direction is opposite to the ventilation window, the outdoor wind direction has little impact on the ventilation. The top frame 5 of the retractable window sash retracts to a position flush with the bottom frame 4, and the side sash 7 retracts into the receiving cavity 301. When the hinged flap on the front sash 6 opens, the retractable window sash forms an airflow channel at the ventilation opening 2, aligned with the direction of the ventilation opening 2, allowing normal ventilation. The retraction of the top frame 5 to flush with the bottom frame 4 reduces the window sash's footprint and prevents dust accumulation on the upper side sash 703. When the outdoor wind speed is high... If the wind is blowing inwards from the ventilation window, it can easily cause drafts, hindering the exhaust of indoor air. In this case, close the first movable flap on the front sash 6 to prevent wind from entering from the front of the sash. At the same time, activate the hydraulic cylinder 8 to open the top frame 5 and open the second movable flap on the side sash 7. Ventilation and exhaust can then be achieved through the side sash 7. Meanwhile, the second movable flap on the side sash 7 can be opened and closed independently. When it is hot in summer, if there is a side wind coming from outside, the airflow direction can be changed by opening the side sash 7 on the side of the incoming wind and closing the side sash 7 on the opposite side of the incoming wind, thereby achieving a better ventilation effect.

[0025] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
