Description

Technical Field

[0001] The utility model relates to the technical field of fire protection, in particular to a manual opening and closing mechanism for a fire smoke exhaust window. Background Art

[0002] The fire smoke exhaust window opening and closing mechanism is an important part of the building design that is used to automatically or manually open the window in an emergency to quickly discharge the smoke, heat and harmful gases inside the building, thereby ensuring the safe evacuation of personnel and reducing fire losses. This type of mechanism is usually linked with the building's fire alarm system, and can automatically respond when the fire starts, or it can be manually operated. The specific functions and structures are as follows: 1. Automatic control: Combined with the fire alarm system, when the detector senses that the smoke and temperature exceed the set value, the linkage controller sends a signal, the electric smoke exhaust window mechanism automatically starts, and the window opens. 2. Manual operation: In emergency situations or tests, manual switches or mechanical pull rods and buttons can directly open the smoke exhaust window, which is convenient for flexible control. 3. Power redundancy: The design is equipped with battery backup, and the main power can still be operated when the power is off to ensure emergency operation. 4. Detection and feedback: There is a feedback mechanism to report the window opening status to the fire control room for easy monitoring and recording. 5. Closing mechanism: When the fire alarm is lifted or the smoke exhaust is completed, it can be automatically or manually reset according to the settings, and the window can be electrically closed to prevent dust and wind and rain. 6. Structure: The structure is stable, fire-resistant and high-temperature-resistant, anti-corrosion, easy to maintain, and adaptable to harsh environments. 7. Installation: Comply with building standards, position, quantity, size, height, angle calculation, and consider building ventilation, escape, and smoke flow. The design and installation of the fire smoke exhaust window opening and closing mechanism is a key part of fire safety regulations. It must comply with the regulations of the local fire department to ensure rapid and effective smoke exhaust in the event of a fire, buy time for escape and rescue, and reduce losses.

[0003] In the prior art, a hand-cranked gear transmission assembly is mainly used to drive the main shaft of the window to rotate, thereby realizing the opening and closing effect of the window sill. However, the transmission efficiency of this opening and closing device is very low, that is, it is difficult to open a large area in a short time, and fires are generally very urgent, which causes a certain delay in rescue operations and is not conducive to the first-time search and rescue of personnel.

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a manual opening and closing mechanism for a fire smoke exhaust window.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0012] According to a further technical solution, a handle is provided at the end of the cotton rope.

[0013] According to a further technical solution, the rollers and the guide rods are symmetrically distributed on both sides of the window frame.

[0014] As a further technical solution, the cotton rope is made of reinforced toughness material.

[0018] By setting up the buffer plate and sliding box damping groove structure, the window will not hit the windowsill directly when it is stored, but will be slowly buffered to the windowsill to be closed, which avoids the problem of damage caused by excessive movement of the windowsill.

[0019] In order to prevent the window from falling quickly when being lowered inside the windowsill, and then hitting the windowsill and damaging the window, we use an anti-fall component; the main principle of the anti-fall component is to realize transmission by clamping the groove wheels on both sides on the surface of the cotton rope, and at the same time, a damping bearing is installed on the groove wheel shaft to prevent the cotton rope from moving too quickly and causing the window to fall quickly, thereby ensuring the safety of the device during use.

[0020] This structure is combined with the structure of the fire-fighting window sill, which solves the problem of traction of fire-fighting facilities in accordance with local conditions and avoids occupying a large amount of indoor space. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Working principle:

[0040] In the actual setting process of the utility model, the following technical problems existing in the prior art are solved: the prior art mainly adopts a hand-cranked gear transmission component to drive the main shaft of the window to rotate, thereby realizing the opening and closing effect of the window sill. However, the transmission efficiency of this opening and closing device is very low, that is, it is difficult to open a large area in a short time, and fires are generally very urgent, which causes a certain delay in the rescue operation and is not conducive to the rescue of personnel in the first time. A manual opening and closing component 2 for the smoke exhaust window is proposed;

[0041] When a fire occurs and fire rescue is required, the locking member 15 is manually unscrewed to disengage the locking member 15 from the squeezing cotton rope 7. The handle 16 is held and the cotton rope 7 is pulled outward. The cotton rope 7 is guided and driven by the roller 8 and the guide rod 9, and the transmission ratio has the advantage of full transmission compared to the gear transmission. The end of the cotton rope 7 pulls up the window 5, so that the window 5 is pulled upward from the inside of the window frame 3, while exposing the fire escape passage inside the window frame 3. Finally, the locking member 15 is locked again inside the sliding box 13 to prevent the window 5 from falling and causing risks.

[0042] When the window 5 needs to be retracted after use, it is only necessary to loosen the locking piece 15 and the cotton rope 7. During the process, it is necessary to pay attention to controlling the force of loosening the rope to prevent the window 5 from violently hitting the window frame 3; in order to avoid this situation to the greatest extent, the inside of the sliding box 13 is set as a damping groove 14, and the bottom of the window 5 is also provided with a buffer plate 6 to buffer this impact force. At the same time, in order to prevent the window 5 from falling rapidly during the process of being lowered inside the window sill 12, and then hitting the window sill 12 to damage the window 5, we use an anti-falling assembly 17; the anti-falling assembly 17 is used to increase the damping effect of the sliding box 13 to ensure the overall safety of the device. The main principle of the anti-falling assembly 17 is to realize transmission by clamping the groove wheels 23 on both sides on the surface of the cotton rope 7, and at the same time, a damping bearing 22 is installed on the rotating shaft of the groove wheel 23 to prevent the cotton rope 7 from moving too fast, thereby causing the window 5 to fall rapidly, thereby ensuring the safety of the device during use.
