Description

Technical Field

[0001] The utility model relates to a fire rescue device for the facade of a high-rise building, belonging to the technical field of building fire rescue. Background Art

[0002] For fires on the facades of high-rise buildings, there are currently the following effective fire-fighting equipment and devices: high-rise jet fire trucks, fire-fighting unmanned helicopters, exterior wall water curtain sprinkler devices and hanging basket-type fire-fighting systems.

[0003] There is a height limitation for high-lift jet fire trucks in firefighting on the facades of high-rise buildings. The highest height of high-lift jet fire trucks currently designed is 62 meters, and fires above this height cannot be effectively extinguished.

[0004] The unmanned helicopter takes off with a fire hose and can spray water or foam directly on the fire wall to extinguish the fire. Since the weight of the fire hose hung by the unmanned helicopter increases with the increase of height, the lifting height will also be subject to certain restrictions.

[0005] A sprinkler fire extinguishing device similar to that used indoors is installed on the top of a high-rise building. The sprinkler head is installed on the outside of the top of the building, facing the wall. After the sprinkler system is activated, the water sprayed from the sprinkler head will flow down along the wall, playing a certain role in controlling the fire on the building's facade from spreading upward. Since the water volume of the sprinkler system is small, it is not easy to aim at the fire location, and in many cases, the fire cannot be extinguished.

[0006] Comparison patent:

[0008] 2) Document No. CN111544817A, a super high-rise building fire extinguishing system and method, published on August 18, 2020; this utility model uses a compressed air foam generating device to quickly transport compressed air foam to any floor through a fixed foam fire extinguishing pipeline installed on the high-rise facade.

[0009] 3) Document number CN114870304A is a hanging basket type high-rise building fire-fighting device, published on August 9, 2022; this utility model can move the water pipe and the booster pump upward to a certain height by setting a hanging basket body, a connecting valve, a water pipe, a scale, a driving motor, a steel rope and a rotating rod. The booster pump can boost the water in stages, thereby increasing the range and flow rate of the water so that the water can be sprayed to the fire point outside the high-rise building.

[0010] 4) Document No. CN116531689A A high-rise building fire-fighting device, published on August 4, 2023; the utility model installs the fire-fighting device on the building, including a water tank, a booster pump, a water pipe and an installation cabinet arranged on the top floor of the building. One end of the booster pump is connected to the water tank and the other end is connected to the water pipe. The water outlet of the water pipe is passed through and movably installed on the installation cabinet. The water outlet is connected to a water spraying mechanism, and the installation cabinet is connected to a lifting mechanism and an extension mechanism. The installation cabinet is moved to the position of the designated floor by the lifting mechanism, and then the water outlet is driven to the window of the room where the fire occurs through the extension mechanism, and then further positioned by the water spraying mechanism to spray water, thereby automatically aligning the fire hose to the fire scene, realizing fire fighting in high-rise buildings.

[0011] 5) Document No. CN116920313A A fire-fighting device for high-rise buildings, published on October 24, 2023

[0012] The utility model includes a track, a support frame, a lifting frame and a water spray pipe. The track is fixed on the roof of a high-rise building. The support frame slides with the track. The support frame is connected to the lifting frame through an upper pull rope. The lifting frame is suspended on one side of the high-rise building. A water spray pipe is arranged in the lifting frame. A nozzle is arranged on the side wall of the water spray pipe. The water spray pipe is connected to a high-pressure water pump through a water inlet pipe.

[0013] It can be seen that the existing hanging basket type high-rise building fire extinguishing system has the following disadvantages:

[0014] Disadvantages of existing technology:

[0015] 1) It requires the cooperation of ground mobile fire-fighting equipment. The hanging basket itself does not have the fire-fighting ability. It is necessary to rely on firefighters to extinguish the fire and rescue in the hanging basket. The fire-fighting and rescue positions are fixed;

[0016] 2) Firefighting equipment must be installed on all sides of high-rise buildings, and the lifting mechanism must be fixed to the building, which is easily damaged by fire on the facade and causes failure, thus losing the firefighting ability;

[0017] 3) Insufficient stability. As the lifting frame moves down to a lower position, the accuracy of water spraying and fire extinguishing will be reduced due to the influence of wind force and the reaction force of water spraying. Utility Model Content
