Description

Rotatable hook device for external rescue of high-rise buildings

technical field

The invention belongs to the technical field of firefighting and rescue equipment, in particular to a rotatable hook device for external rescue of high-rise buildings.

Background technique

Rescue for high-rise disasters such as high-rise and super high-rise building fires has always been a difficult problem in the field of fire protection. With the acceleration of urban modernization, urban land use has become increasingly tight, and high-rise buildings have sprung up like mushrooms after rain. Observers predict that China will build no less than 50,000 high-rise buildings in the next 20 years, and high-rise buildings have the characteristics of many vertical shafts, many combustibles, many floors, long vertical distances, dense personnel, and complex functions. When a fire breaks out, the fire often spreads rapidly, the evacuation is difficult, the firefighters are physically exhausted, and the fire supply is difficult to ensure, which brings great difficulties to the fire fighting work. This has become an important issue of widespread concern around the world. The implementation of external attack is an important tactical measure to extinguish high-rise building fires. However, there are still many unfavorable factors in the rescue of high-rise building fires, such as insufficient fire-fighting climbing ability, few evacuation methods, difficult rescue, blocked fire attack, and large fire-fighting water consumption. , difficulty in exhausting smoke, etc. Judging from the current practice of fire fighting in high-rise buildings, the existing external rescue equipment such as elevating fire-fighting vehicles still has the following problems: first, it cannot be equipped in large quantities in small and medium-sized cities due to its high price; Long and low rescue efficiency, especially restricted by the surrounding environment and space (roads, podiums, etc.) of high-rise buildings, resulting in the existence of "combat blind spots" on the fire scene; The high-rise building fire that raises height fire-fighting vehicle then seems powerless at present. At the same time, fires in high-rise buildings also show new characteristics of going from outside to inside, from high to low. For fires caused by the outside of the building, it is more difficult to rescue the fire caused by the outside of the building because it does not have complete fire separation facilities and fixed fire extinguishing facilities inside the building. Similarly, once a fire breaks out in a hazardous chemical storage location, conventional firefighting equipment cannot quickly approach the fire area. Using unmanned aerial vehicles to quickly enter the dangerous area for fire reconnaissance or replace manual execution of some fire fighting and rescue tasks can greatly reduce losses and improve rescue efficiency. , to gain time. A reasonable external rescue plan can use drones to drop rescue equipment and build rescue channels. Most of these solutions require setting hooks on the top of high-rise buildings or other designated rescue locations to provide a focus for drones to drop rescue equipment. However, the existing hooks cannot meet the requirement that the noose is randomly dropped and hit when the unmanned aerial vehicle is used for external rescue. Therefore, it is necessary to develop a special high-rise building external rescue rotatable hook device to make up for the deficiencies in the prior art.

Contents of the invention

The purpose of the present invention is to address the deficiencies in the prior art, to provide a rotatable hook device for external rescue of high-rise buildings, to provide a starting point for drones to drop rescue equipment, so that rescuers are not limited by the height of buildings at the fire site, and are convenient Implement multi-point rescue, deliver the first batch of necessary rescue equipment to designated rescue locations as soon as possible, help rescuers build rescue channels, and rescue trapped people from the disaster scene.
