[0002] Traditional high-rise building firefighting methods primarily rely on ladder trucks, indoor fire hydrant systems, and manual firefighting by firefighters. However, these methods have numerous limitations when it comes to combating high-rise building fires. Given the significant challenges faced by high-rise building firefighting and the shortcomings of existing firefighting methods and drones, the development of a drone specifically designed for high-rise building firefighting is of great practical significance.

[0003] Currently, among the existing high-rise firefighting drones, such as the patent with authorization announcement number CN207311843U, this high-rise building firefighting drone can extinguish fires from above through the drone. The high-rise building firefighting drone includes: a heavy-duty drone body, a water pump, pipes and nozzles installed at the bottom of the body, a fixing device for firefighting equipment at the bottom of the body, a soft water pipe connecting the drone and the ground, a water pump, pipes and valves on the ground, and a fire hydrant.

[0004] However, during the use of this drone, it was found that its functionality was relatively simple, which reduced the efficiency of fire extinguishing. In addition, when encountering closed windows on high floors, it was unable to spray water into the room to extinguish the fire, which increased the limitations of its use. Summary of the Invention

The water flow direction is controlled by the delivery device so that the water is delivered to the inside of the second delivery pipe. The water entering the second delivery pipe flows through the first sleeve and the first delivery pipe, so that the fire extinguishing bomb in the first sleeve is pushed during the water flow, so that the fire extinguishing bomb is launched outward to the fire position, thereby achieving a combined efficient fire extinguishing effect of water and fire extinguishing bombs, and by moving and connecting the window breaking assembly to be set in the gap between the first delivery pipe and the second delivery pipe, the power of the water flow pushes the window breaking assembly to shatter the glass, thereby achieving an efficient window breaking fire extinguishing effect, improving the safety of fire fighting, and reducing usage limitations.

At this time, the blocking device blocks between the second delivery pipe and the connecting pipe, so that water cannot enter the inside of the second delivery pipe. The water in the connecting pipe enters the inside of the multiple groups of cylinders through multiple groups of hoses, so that the water pushes the multiple groups of piston rods to move. After the multiple groups of piston rods move, they drive the two groups of sealing kits to move, so that the two groups of sealing kits seal the gaps between the first delivery pipe, the second delivery pipe and the first sleeve. Then the blocking device is opened to allow water to quickly enter the inside of the second delivery pipe, so that the water flow pushes the fire extinguishing bomb or the window breaking component to be delivered, thereby enhancing kinetic energy and improving the effect of fire extinguishing and window breaking.

Two sets of elastic side plates 501 are slidably installed in the reduced diameter channel 404. The breaking ball 502 is arranged between the two sets of elastic side plates 501. Multiple sets of elastic support sheets 503 and limiting rings 504 are respectively arranged on the inner side walls of the reduced diameter channel 404.

[0037] The intercepting device includes a blocking member 801 and a second motor 802. The blocking member 801 is rotatably arranged inside the conveying box 201.

[0041] Example 3

[0042] Based on Example 1, the present invention provides a drone for high-rise building firefighting, further comprising a connecting frame 601, a rod 602, a second tension spring 603, and a fixing seat 604.

When multiple groups of insertion rods 602 are inserted into the fixing seat 604, the second electric cylinder 701 drives the limit plate 702 to move downward, so that the limit plate 702 supports and limits the upper part of the multiple groups of insertion rods 602, thereby fixing the rotation of the multiple groups of insertion rods 602, and improving the connection firmness between the connecting frame 601 and the box 102.

[0044] like Figures 1 to 10 As shown, a drone for high-rise building firefighting of the present invention connects a delivery device to external firefighting equipment via a pipeline during operation. By controlling the drone body 101 to fly to a fire extinguishing location, water is pumped into the delivery device at high pressure by the external firefighting equipment, causing the water spray pipe 103 to spray water outward to extinguish the fire. One set of first sleeves 106 is moved to the gap between the first delivery pipe 104 and the second delivery pipe 105, and the first delivery pipe 104, the second delivery pipe 105, and the first sleeve 106 are connected. The delivery device controls the direction of water flow so that water is delivered to the interior of the second delivery pipe 105.

[0047] 2. The water flow pushes the elastic side plates 501 outward, which in turn drives the crushing balls 502 outward. When the elastic side plates 501 and the crushing balls 502 move out of the reduced diameter channel 404, the two sets of elastic side plates 501 are displaced to one side by air resistance, while the crushing balls 502 continue to disperse and move forward due to inertia, shattering the window glass, thereby improving the window breaking effect.
