Description

Technical Field

[0001] The present invention relates to the technical field of fire smoke exhaust, in particular to a window-type electric mobile fire smoke exhaust machine. Background Art

[0002] In fire accidents, thick smoke is a key factor hindering rescue and endangering lives. There are many limitations in traditional smoke exhaust equipment. Currently, mobile fire smoke exhaust machines driven by internal combustion engines and water-driven mobile fire smoke exhaust machines are mainly used. The above two types of mobile fire smoke exhaust machines have the following disadvantages when used in high-rise residential buildings: Limited smoke exhaust effect and capacity: High-rise residential buildings have large building spaces and high vertical heights. The amount of smoke generated by fires is large and the diffusion range is wide. Calculated based on an area of 100 square meters per suite and a floor height of 3 meters, the total room volume is 300 cubic meters. Due to the layout position problem of internal combustion engine-driven and water-driven mobile fire smoke exhaust machines (which can only be arranged at the door far from the fire source), the smoke exhaust volume is limited, making it difficult to achieve the purpose of overall air replacement in the entire room, difficult to effectively discharge a large amount of smoke in a short time, and difficult to meet the large-scale smoke exhaust requirements of high-rise residential buildings, thus affecting the evacuation of personnel and the development of fire rescue work.

[0003] · Inconvenient to move and operate: The stairwells in high-rise residential buildings are narrow and there may be evacuating people. Internal combustion engine-driven and water-driven mobile smoke exhaust machines are large in volume and heavy in weight, making it difficult to carry them to high-rise floors. Moreover, when moving and operating in narrow spaces such as stairwells, they are easily blocked, affecting their rapid deployment and use.

[0004] · Greatly affected by building structure and layout: The building structures of high-rise residential buildings are complex, with multiple rooms, corridors, stairwells, etc. Internal combustion engine-driven and water-driven mobile fire smoke exhaust machines usually can only blow air towards the fire source at the position of the room door for smoke exhaust. For some areas far from the placement position of the smoke exhaust machine, such as the smoke in corners and enclosed rooms, it is difficult to effectively exhaust, and the smoke exhaust effect will be restricted by the building structure and layout.

[0005] · Problems of water source and gas source pollution: Water-driven mobile fire smoke exhaust machines need to be connected to an external high-pressure water source or equipped with a special high-pressure pump as a power source. At the fire scene of high-rise residential buildings, there may be a situation where the fire water source system is damaged and cannot supply water normally, and the water source should be given priority to fire extinguishing, so there may be no water source when using water-driven smoke exhaust machines. And using an internal combustion engine-driven mobile fire smoke exhaust machine requires ensuring sufficient fuel supply, and the engine will generate noise and exhaust gas when running, which may cause additional harm to personnel in a relatively enclosed high-rise indoor environment, and the problem of exhaust gas emission also needs to be considered.

[0006] · High requirements for coordinated cooperation: When using a mobile fire smoke exhaust fan in high-rise residential buildings, it is necessary to closely cooperate with other fire-fighting equipment and rescue operations. For example, it is necessary to coordinate with the laying of fire hoses and the setting of evacuation passages for personnel. If the cooperation is improper, the function of the smoke exhaust fan may not be fully exerted, and even the efficiency of the entire fire rescue work may be affected. Summary of the Invention

A placement groove 1 3 and a placement groove 2 4 are provided on the top of the main body 1. Telescopic rod fixing plates 5 are provided on both the placement groove 1 3 and the placement groove 2 4. Telescopic rod fixing clips 6 are provided on the telescopic rod fixing plates 5. A telescopic rod 7 is provided on the telescopic rod fixing clip 6. A telescopic rod top fixing piece 8 is provided on the top of the telescopic rod 7; In this embodiment, folding and hidden handles 9 are provided on both the top and the side of the main body 1. An air duct assembly 10 is provided on the main body 1. A bracket fixing plate is provided on the side wall of the main body 1. An inverter, a motor controller, a long bracket and a short bracket are provided inside the main body 1. A mains power conversion switch 11, a switch 12 and a mains power interface 13 are also provided on the side of the main body 1. The inverter, the motor controller, the battery and the air duct assembly are electrically connected, and it is prior art.

[0022] In this embodiment, the bottom groove strip 2 is made of rubber material, and at least two grooves are provided on the bottom groove 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 wind blades and can play a role in guiding the flow.

[0023] 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 a battery baffle 16. The top of the telescopic rod top fixing piece 8 is serrated.

[0024] In this embodiment, the air duct assembly 10 includes a cover air duct 17, a rear air net 18, a motor screw fixing sleeve 19, and a motor 20. The main body 1 also includes a cover plate 21, which is driven by electric energy. During operation, it will not emit harmful exhaust gases such as carbon monoxide and hydrocarbons like an internal combustion smoke exhaust fan. At the fire scene, especially in the indoor space, a clean air environment is very important, which can not only avoid secondary damage to the respiratory tract of trapped persons, but also reduce the potential threat to the health of rescue firefighters, and will not increase the pollution burden of the surrounding environment. The length, width and height of the main body 1 are 650x210x650mm respectively. After the electric smoke exhaust fan is powered on, press the start button and it can reach the rated speed and start the smoke exhaust operation in just a few seconds; in contrast, the internal combustion smoke exhaust fan has to go through cumbersome steps such as checking the fuel and preheating the engine, which takes a long time; in the fire rescue scene where every second counts, the window-type electric fire smoke exhaust fan can respond quickly, seize the opportunity for personnel evacuation and fire fighting, and at the same time, the size cannot be too large. Too large size is not convenient for single-person use and is not conducive to smoke exhaust.

[0028] The working principle of the present invention 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 area is formed at the fan inlet, and the indoor smoke is quickly sucked in; the sucked smoke is accelerated by the fan and discharged out of the window or discharged to the designated outdoor area through the smoke exhaust pipe to achieve rapid smoke exhaust; after the electric smoke exhaust machine is powered on, press the start button, and it can reach the rated speed and start the smoke exhaust operation in just a few seconds; in contrast, the internal combustion smoke exhaust machine has to go through tedious steps such as checking the fuel and preheating the engine, which takes a long time. In the fire rescue scene where every second counts, the window-type electric fire smoke exhaust machine can respond quickly and seize the opportunity for personnel evacuation and fire fighting; without the complex mechanical structure of the internal combustion engine, there is no need to frequently replace consumables such as engine oil, spark plugs, filters, etc. Its main maintenance work is concentrated on the routine inspection and maintenance of the motor, electrical circuit and fan components, which not only saves manpower, material and financial resources, but also reduces the downtime caused by equipment failure maintenance, ensuring that the smoke exhaust machine is available at any time.

[0029] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention 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 perform equivalent replacements for some of the technical features.
