Description

Technical Field

[0001] This utility model relates to the technical field of fire smoke extraction, and in particular to a window-type electric mobile fire smoke extraction machine. Background Technology

[0002] In fire accidents, dense smoke is a key factor hindering rescue efforts and endangering lives. Traditional smoke extraction equipment has many limitations, and currently, mobile fire-fighting smoke extraction fans powered by internal combustion engines and water-driven mobile fire-fighting smoke extraction fans are the main types used. These two types of mobile fire-fighting smoke extraction fans have the following disadvantages when used in high-rise residential buildings:

[0003] • Limited smoke extraction efficiency and capacity: High-rise residential buildings have large spaces and high vertical heights, resulting in large volumes of smoke that spread widely during fires. Assuming each apartment is 100 square meters with a floor height of 3 meters, the total room volume is approximately 300 cubic meters. Due to the limited placement of internal combustion and water-driven mobile fire exhaust fans (which can only be placed far from the fire source near doorways), the smoke extraction capacity is limited. This makes it difficult to completely replace the air in the entire room, effectively remove large amounts of smoke in a short time, and meet the large-scale smoke extraction needs of high-rise residential buildings, thus affecting personnel evacuation and fire rescue operations.

[0004] • Inconvenient to move and operate: Stairwells in high-rise residential buildings are narrow and may contain evacuation personnel. Internal combustion and water-driven mobile smoke exhaust fans are large and heavy, making them difficult to move to upper floors. Moreover, they are easily obstructed when moving and operating in narrow spaces such as stairwells, affecting their rapid deployment and use.

[0005] • Significantly affected by building structure and layout: High-rise residential buildings have complex structures with multiple rooms, corridors, and stairwells. Internal combustion and water-driven mobile smoke exhaust fans can usually only blow air towards the fire source at the room entrance to exhaust smoke. For areas far from where the smoke exhaust fan is placed, such as corners or enclosed rooms, smoke is difficult to exhaust effectively, and the smoke exhaust effect is limited by the building structure and layout.

[0006] • Water and air pollution issues: Water-driven mobile fire exhaust fans require an external high-pressure water source or a dedicated high-pressure pump as their power source. In high-rise residential fires, the fire hydrant system may be damaged and unable to supply water normally, and water must be prioritized for firefighting. Therefore, using water-driven exhaust fans may result in a lack of water supply. Using internal combustion mobile fire exhaust fans, on the other hand, requires ensuring a sufficient fuel supply, and the engine generates noise and exhaust fumes, which may pose additional hazards to people in the relatively enclosed indoor environment of a high-rise building. The issue of exhaust emissions also needs to be considered.

[0007] • High level of coordination required: When using mobile fire exhaust fans in high-rise residential buildings, close coordination with other fire-fighting equipment and rescue operations is necessary. For example, coordination with the laying of fire hoses and the establishment of evacuation routes is required. Improper coordination may prevent the exhaust fans from functioning effectively and could even affect the efficiency of the entire fire and rescue operation. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0027] like Figures 1-3 As shown, a window-type electric mobile fire smoke exhaust fan includes a main body 1, which has a square structure. The bottom of the main body 1 is provided with a bottom concave strip 2. The top of the main body 1 is provided with a placement slot 1 3 and a placement slot 2 4. Both the placement slot 1 3 and the placement slot 2 4 are provided with telescopic rod fixing plates 5. The telescopic rod fixing plates 5 are provided with telescopic rod fixing clips 6. The telescopic rod fixing clips 6 are provided with telescopic rods 7. The top of the telescopic rods 7 is provided with a telescopic rod top fixing piece 8.

[0028] In this embodiment, the main body 1 is provided with foldable and hidden handles 9 on the top and sides, the main body 1 is provided with a duct assembly 10, the side wall of the main body 1 is provided with a bracket fixing plate, the interior of the main body 1 is provided with an inverter, a motor controller, a long bracket and a short bracket, and the side of the main body 1 is also provided with a mains power conversion switch 11, a switch 12 and a mains power interface 13. The inverter, motor controller, battery and duct assembly are electrically connected and are existing technologies.

[0029] In this embodiment, the bottom concave strip 2 is made of rubber material, and at least two grooves are provided on the bottom concave strip 2. An aluminum alloy protective cover 14 is provided on the side wall of the main body 1. The protective cover can protect the stable operation of the fan blades and can perform airflow guiding function.

[0030] In this embodiment, a battery is also provided on the side wall of the main body 1, and the battery is placed in the battery fixing frame 15. At the same time, the end of the battery fixing frame 15 is fixed by the battery baffle 16, and the top of the telescopic rod top fixing member 8 is serrated.

[0031] In this embodiment, the ventilation duct assembly 10 includes a cover duct 17, a rear ventilation screen 18, a motor screw fixing sleeve 19, and a motor 20. The main body 1 also includes a cover 21. Driven by electric power, it does not emit harmful exhaust gases such as carbon monoxide and hydrocarbons during operation, unlike internal combustion smoke exhaust fans. In fire scenes, especially indoor spaces, a clean air environment is crucial. It can avoid secondary damage to the respiratory tract of trapped personnel, reduce potential threats to the health of rescue firefighters, and does not increase the pollution burden on the surrounding environment. The main body 1 has a length, width, and height of 650x210x650mm. After the electric smoke exhaust fan is connected to the power supply and the start button is pressed, it can reach the rated speed and start smoke exhaust operation within a few seconds. In contrast, internal combustion smoke exhaust fans require cumbersome steps such as checking fuel and preheating the engine, which takes a long time. In fire rescue scenarios where every second counts, the window-type electric fire smoke exhaust fan can respond quickly, giving people an advantage in evacuation and fire fighting. At the same time, the size cannot be too large, as an excessively large size is inconvenient for single-person use and is not conducive to smoke exhaust.

[0032] In this embodiment, the telescopic rod fixing clip 6 is made of aluminum alloy and has a size of 32-36mm. The side wall of the main body 1 also includes a window breaker fixing plate and a window breaker hammer 22. The window breaker hammer 22 can break the window when the window cannot be opened at the fire scene, so that the equipment can be placed on the window.

[0033] In this embodiment, the motor screw fixing sleeve 19 is used to fix the motor 20, and the telescopic length of the telescopic rod 7 is 60-120cm.

[0034] In this embodiment, the window breaker hammer 22 is made of No. 45 steel and is fixed on the window breaker hammer fixing plate. The telescopic rod fixing clip 6 is set on the telescopic rod fixing tube 23.

[0035] The working principle of this utility model is as follows: After the power is turned on, the motor 20 starts quickly, driving the fan impeller to rotate at high speed; through the rotation of the impeller, a negative pressure zone is formed at the fan inlet, rapidly drawing in the smoke from the room; the drawn-in smoke is accelerated by the fan and then discharged outside the window or through the smoke exhaust pipe to a designated outdoor area, achieving rapid smoke exhaust; after the electric smoke exhaust fan is turned on, pressing the start button allows it to reach the rated speed and begin smoke exhaust operation within a few seconds; in contrast, internal combustion smoke exhaust fans require cumbersome steps such as checking fuel and preheating the engine, which takes longer. In the critical fire rescue scenario where every second counts, the window-type electric fire smoke exhaust fan can respond quickly, giving personnel evacuation and fire fighting an advantage; without the complex mechanical structure of an internal combustion engine, it does not require frequent replacement of consumables such as engine oil, spark plugs, and filters. Its main maintenance work is concentrated on routine inspection and maintenance of the motor, electrical wiring, and fan components, which not only saves manpower, material resources, and financial resources, but also reduces downtime caused by equipment failure and maintenance, ensuring that the smoke exhaust fan is always available.

[0036] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
