Example 3

The present example is for explaining the effects of the fire extinguishing apparatus 1 for an outer wall of a high-rise building and the fire extinguishing method 2 for an outer wall of a high-rise building of the present invention.

The high-rise building outer wall fire extinguishing device 1 is arranged at multiple points 1-2 layers below a fire-starting layer, the fire-starting layer and 1-2 layers above the fire-starting layer of a high-rise building in a echelon attack mode from the fire-extinguishing attack starting layer of the high-rise building fire according to the deployment sequence of high-rise fire-extinguishing force, the arrangement position is selected to be close to a window, a balcony and the like of the high-rise building, and each fire-starting vertical surface is arranged.

The electric spraying part 6 of the fire extinguishing device 1 for the outer wall of the high-rise building extends out of the high-rise building from a window of the high-rise building (wherein the length of the quick-connection supporting fixing rod 4 of the fire extinguishing device for the outer wall of the high-rise building after being unfolded is greatly increased, so that the electric spraying part 6 can be ensured to extend out far enough from the inside of the high-rise building to the outside, and the influence of a protruding structure on the outer wall of the high-rise building on the spraying range is avoided).

The fire extinguishing device is connected with a pressurized fire fighting water supply (liquid) hose, so that all-around water discharge or fire fighting foam can be carried out on all-around fire-starting parts of the upper, lower, left and right 360-degree fire-starting parts of the outer wall (outside) of the high-rise building to extinguish the fire, the three-dimensional spread of the fire along the outer wall (outside) of the high-rise building is cut off, and the fire-extinguishing range is controlled in the limited space of horizontal and vertical fire partitions within a certain range, so that ten fire-extinguishing tactics such as interception, breakthrough, segmentation, clamping, combined attack, containment, forcible entry, plugging, smoke discharge, monitoring and the like are effectively implemented, the fire-extinguishing rescue force has the external fire-extinguishing capacity of the high-rise building with any height, and the fire-extinguishing success rate of the high-rise building, particularly the super high-rise building, is greatly improved.

The high-rise building exterior wall fire extinguishing method 2 has the characteristic of no height limitation, and the no height limitation means that the high-rise building exterior wall fire extinguishing device 1 can be arranged at a high-rise building window at any height to carry out external fire extinguishing on a high-rise building.

The fire extinguishing method 2 for the outer wall of the high-rise building has the characteristic of being not limited by wind power, the wind power does not influence the implementation of the fire extinguishing method 2 for the outer wall of the high-rise building, and the fire extinguishing method is difficult to implement when the wind power exceeds 6 levels when the traditional fire extinguishing methods for the high-rise buildings such as a fire extinguishing unmanned aerial vehicle and a lifting fire truck are used.

One of the key points of the fire extinguishing method 2 for the outer wall of the high-rise building is that the electric spraying part 6 of the fire extinguishing device for the outer wall of the high-rise building extends out from the inside of the high-rise building to the outside, and water or fire-fighting foam is sprayed to the fire part on the outer wall (outside) of the high-rise building from the inside of the high-rise building to extinguish fire, so that the fire extinguishing capability of the high-rise fire truck exceeding the maximum lifting capacity can be achieved, and the high-rise building can be prevented from being extinguishedFire behavior along the outer vertical surface of the building outer wall (outside) from outside to inside

The fire extinguishing agent can rapidly spread and expand in a three-dimensional way from inside to outside, and can extinguish fire in a high-rise building outer wall (outer vertical surface) by 'external fire and internal rescue'; the length of the quick-connection supporting fixing rod 4 of the fire extinguishing device 1 for the outer wall of the high-rise building after being unfolded is greatly increased, the electric spraying part 6 can be ensured to extend out far enough from the inside of the high-rise building to the outside, and the influence of a protruding structure on the outer wall of the high-rise building on the spraying range is avoided.

The second key point of the fire extinguishing method 2 for the outer wall of the high-rise building is that the stable water bag 7 of the fire extinguishing device 1 for the outer wall of the high-rise building is centrally placed on the lower support frame 20 of the lower support part 9 of the support and power control part 3 and the telescopic stable support 23, and the fire-fighting lance can quickly play a role in stabilizing the fire extinguishing device 1 for the outer wall of the high-rise building after being filled with water quickly, so that the reaction force brought to the fire extinguishing device 1 for the outer wall of the high-rise building when the electric injection part 6 injects the fire extinguishing agent is counteracted, the overturning of the fire extinguishing device 1 for the outer wall of the high-rise building in use is prevented, the whole weight and the size of the fire extinguishing device 1 for the outer wall of the high-rise building are greatly reduced, the burden of a fire fighter on climbing the building with heavy load is reduced, the physical strength is saved, the fire fighter can rescue the fire in the first time and the first time, and the fire extinguishing efficiency is improved.

The third key point of the fire fighting method 2 for the high-rise building outer wall is that the fire fighting water supply method adopts a mode of carrying out multistage coupling pressurization water supply by a plurality of fire trucks, a plurality of fire-fighting hand-lifting motor-driven pumps and a plurality of fire-fighting transfer water bags to supply fire fighting water, so that the fire fighting water is ensured to be delivered to the positions near the fire fighting floors of the high-rise building, when the flow and the pressure of the tail fire-fighting water are insufficient, the fire-fighting transfer water bags and the fire-fighting hand-lifting motor-driven pumps can be additionally arranged at the tail end, the water for indoor fire hydrant at the positions of the tail end floors and the positions near the upper, lower, left and right fire zones is conveyed into the additionally arranged fire-fighting transfer water bags through fire hoses, and then the water is sucked and pressurized through the plurality of fire-fighting hand-lifting motor-driven pumps, so that the fire fighting water supply with sufficient flow and pressure is continuously provided for the fire fighting device 1 on the high-rise building outer wall, and the fire fighting device 1 of the high-rise building can be arranged at any height and is not limited by the height of the water supply height.

Different from chemical fire or fire extinguishment of low-rise and multi-rise buildings, fire fighting water supply of high-rise and especially super high-rise buildings is very difficult, firstly, high-reliability uninterrupted sustainable water supply is required, large-flow water supply which is difficult to realize is not pursued, secondly, the flow, the pressure and the shooting range are enough, the smaller the flow, the higher the water supply height is, the higher the uninterrupted sustainable water supply reliability is, the more danger of 'ash and reburning' after water supply interruption can be reduced, and the more potential danger brought to rescue workers and rescued people after water supply interruption can be reduced.

When the 'echelon attack' fire extinguishing tactic is implemented, a plurality of sets of high-rise building outer wall fire extinguishing devices 1 can be arranged in different water jet places simultaneously to extinguish fire so as to improve the fire extinguishing efficiency, conditionally can be arranged in the water jet places in a front-mounted manner, and a plurality of sets of high-rise building outer wall fire extinguishing devices 1 are preset in the high-rise building, so that the high-rise building fire can be better 'early, small and hit' and eliminated at the initial stage.

Although the present invention has been described to a certain degree, it will be apparent that various modifications may be made without departing from the spirit and scope of the invention. It is to be understood that the invention is not to be limited to the described embodiments, but is to be accorded the scope of the appended claims, including equivalents of each element described.
