Description

Technical Field

[0001] The utility model belongs to the technical field of fire escape devices, and particularly relates to a multifunctional window sill fixer for fire rescue. Background Art

[0002] With the continuous advancement of China's modernization drive and urbanization process, modern high-rise buildings in cities are emerging in an endless stream. While modern buildings reflect the grand urban landscape, they also bring many conveniences to people's lives. However, various buildings also have the problem of poor safety. Due to the complex building structure and dense population, once a fire or other emergencies occur on a certain floor, it is particularly important to achieve efficient and safe fire rescue. Currently, in fire rescue, when firefighters receive a fire alarm in a building, they will quickly enter the interior of the building according to the on-site situation. Firefighters wear fire suits and gas masks and enter the interior through the windows of the building, thus shuttling through the fire scene indoors. Therefore, in the process of fire rescue, firefighters need to use safety ropes to achieve their own safe fixing and movement. However, there are generally no fixed points for hanging safety ropes on the existing buildings, especially on one side of the window. It is also impossible for firefighters to drill holes on the spot with electric tools such as electric drills because time is pressing after the fire breaks out, and firefighters lack understanding of the relevant building conditions. At the same time, for the masses who need to escape from the window, they usually use a slow descent escape rope to quickly evacuate from a high place to a safe area on the ground. However, there are also no effective anchor points for fixing the slow descent escape rope at the existing window sill position, thus unable to guarantee the escape efficiency. More fatally, when extinguishing a fire in a building, especially a high-rise building, it is necessary to install a fire hose from the fire hydrant on the ground, and then pull the fire hose into the window of the floor where the fire occurs and penetrate it into the interior for water supply. However, when the fire hydrant is opened, the fire hose expands instantly under the high pressure of water, resulting in the fire hose shaking. There are also no anchor points for fixing or guiding the fire hose at the existing building window sills, and the fire hose is prone to large swings or falling. The general method of fixing the fire hose in the existing building is usually to tie the fire hose to a pillar beside the window sill or fix it on a firm object. However, in the process of fire extinguishing, it is not always possible to find a firm object like a pillar to fix the fire hose, and the fire hose will expand during water supply, and this method cannot ensure the stability of the fire hose during water supply, resulting in a significant reduction in the fire extinguishing function.

[0003] In view of the above situation, it is necessary to set up a fixing device that can be quickly and firmly fixed on the window sill, so as to achieve reliable fixation of the fire hose and improve the efficiency of fire extinguishing and rescue. Therefore, the applicant has made a beneficial design, and the technical solution to be introduced below is generated under this background. Content of the Utility Model
