Description

TECHNICAL FIELD

[0001] The utility model relates to the field of fire fighting tools, especially relates to a vertical spread water gun for putting out fires on the facade of a multi-storey building. BACKGROUND

[0002] A fire water gun is a special device used for extinguishing fires, usually used in conjunction with a fire hose. It sprays water to extinguish the fire source. Its design and function determine the efficiency and safety of fire extinguishing, especially in high-rise buildings or large area fires, the fire water gun plays a vital role. The main body of the water gun is usually made of corrosion-resistant materials such as aluminum alloy or stainless steel, which can withstand high-pressure water flow. The front end of the water gun is designed to adjust the shape and intensity of the water flow. Common nozzle types include straight-line water flow, suitable for long-distance fire extinguishing. The basic principle of the fire water gun is to deliver water to the water gun through the water pump, and spray water flow to the fire source through the nozzle. The water flow is usually in a high-pressure state to ensure that it covers a wider range and extinguishes the fire source. During the water flow spraying process, the nozzle of the water gun can change the shape and intensity of the water flow through the adjusting valve to adapt to different fire scenes.

[0003] However, the following problems are often encountered in the prior art:

[0004] (1) The traditional fire extinguishing equipment may not be able to distribute water flow evenly or adjust it accurately, resulting in some fire sources not being effectively extinguished, affecting the efficiency of fire extinguishing, especially in complex environments such as high-rise buildings, where fire sources may be distributed at different locations. This greatly increases the difficulty of fire extinguishing.

[0005] (2) When extinguishing high-rise fires, to prevent the fire on the bottom floor from spreading vertically through the facade of the wall, firefighters need to climb to the high-rise and spray water from the window to extinguish the fire. Firefighters need to hold the water pipe for a long time to ensure stable water supply when extinguishing high-rise fires, but this method is prone to exposure to dangerous environments such as fire sources, smoke, and heat waves, which can reduce evacuation time and increase the risk of injury and death, posing a safety hazard. INVENTION CONTENTS

[0006] The main purpose of the utility model is to provide a vertical spread water gun for putting out fires on the facade of a multi-storey building, which solves at least one problem mentioned in the background art to some extent.

[0007] To achieve the above-mentioned purpose, the technical scheme adopted by the utility model is:

[0008] A vertical spread water gun for putting out fires on the facade of a multi-storey building, comprising:

[0009] A main water pipe;

[0010] A three-way connector, one of the interfaces of the three-way connector communicates with the main water pipe;

[0011] Branch pipes, at least two of which are provided, each of which is connected to the remaining two ports of the tee interface. The diameter of one end of each branch pipe is larger than the diameter of the other end, and the smaller port of any two branch pipes can be connected to the larger port.

[0012] Multiple branch pipes are provided, and each branch pipe is equipped with the multiple branch pipes, which are installed side by side and parallel to each other on the branch pipe.

[0013] A first fixing rod, one end of which is installed on the body of the main water pipe;

[0014] The second fixing rod has one end installed on the main water pipe. The second fixing rod is parallel to the first fixing rod, and there is a gap between the first fixing rod and the second fixing rod.

[0015] Also includes:

[0016] A screw, one end of which passes through the top end of the second fixing rod, and the screw is threadedly connected to the second fixing rod;

[0017] A force-applying rod, one end of which is fixedly connected to the other end of a screw;

[0018] A baffle is installed laterally on the main water pipe, and the baffle is located in the gap between the first fixing rod and the second fixing rod.

[0019] Also includes:

[0020] Drainage holes are provided in the pipe bodies of the plurality of branch pipes;

[0021] Two sealing caps are provided, which cover the unconnected ends of the two branch pipes.

[0022] The two diverter pipes on the outer edge of the plurality of diverter pipes have their drain holes tilted outwards.

[0023] The drainage holes of the remaining branch pipes extend perpendicularly to the ground.

[0024] The drainage holes are arranged horizontally.

[0025] The large ports of any two of the branch pipes have the same diameter as the tee connector.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] (1) Through the design of the diversion pipe, the angle of the water flow can be adjusted according to the specific location of the fire source to expand the spraying range and achieve simultaneous fire suppression at multiple points. The spray nozzle design of the diversion pipe ensures that the water flow can cover multiple locations on the facade of high-rise buildings, effectively suppressing the spread of fire. Through the detachable design and flexible adjustable branch pipe and diversion pipe system, the equipment can adapt to the facades of buildings of different heights and structures. This means that it can be quickly deployed and used in both high-rise buildings and low-rise buildings.

[0028] (2) The design of the fixing rod and screw allows the water gun to be securely fixed to the building's windows, preventing the water hose from shifting or becoming unstable under high-pressure water flow, which could affect the fire extinguishing effect. The addition of a baffle further ensures a stable water spray and can resist interference from the fire source. Because the water gun can be securely fixed to the exterior of the building, firefighters do not need to hold the water hose in contact with the fire source for extended periods, reducing their risk of exposure to the fire source. At the same time, the equipment's efficiency and stability minimize the risks during fire extinguishing. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] like Figs. 1-2 As shown, a water gun for extinguishing vertically spreading fires on the exterior facade of multi-story buildings includes: a main water pipe 1, a T-junction 2, branch pipes 3, multiple diversion pipes 4, a first fixing rod 5, and a second fixing rod 6. One of the interfaces of the T-junction 2 is connected to the main water pipe 1. At least two branch pipes 3 are provided, each connected to the remaining two interfaces of the T-junction 2. The T-junction 2 serves as the water flow distribution center, distributing the water flow from the main water pipe 1 to the two branch pipes 3. This design ensures efficient water flow distribution to different areas, especially through the diversion pipes connected to the branch pipes 3. Through reasonable water flow distribution, the fire on the exterior facade of multi-story buildings can be effectively extinguished. The diameter of one end of the branch pipe 3 is larger than the diameter of the other end, and the small port of any two branch pipes 3 can be connected to the large port. Each branch pipe 3 has multiple diversion pipes 4 installed on its body. The diversion pipes are installed side by side in parallel on the body of the branch pipe 3. One end of the first fixing rod 5 is installed on the body of the main water pipe 1, and one end of the second fixing rod 6 is installed on the body of the main water pipe 1. The second fixing rod 6 and the first fixing rod 5 are in a parallel position, and there is a gap between the first fixing rod 5 and the second fixing rod 6.

[0036] In this invention, to cope with high water pressure and ensure portability, the tee connector 2 can be made of high-pressure resistant plastics such as polycarbonate or aluminum alloy, capable of withstanding the pressure of water flow while maintaining a light weight for easy operation and carrying by firefighters. When operating on the exterior facade of high-rise buildings, the tee connector 2 can effectively distribute water flow without direct contact with the fire source, ensuring water supply to multiple branch pipes 4, and is suitable for various building types such as office buildings, residential buildings, and shopping malls.

[0037] In this embodiment, one end of the screw 7 passes through the top of the second fixing rod 6, and the screw 7 is threadedly connected to the second fixing rod 6. One end of the force-applying rod 8 is fixedly connected to the other end of the screw 7. The baffle 9 is horizontally installed on the body of the main water pipe 1, and the baffle 9 is located in the gap between the first fixing rod 5 and the second fixing rod 6. The main function of the fixing rod and the screw 7 is to stably fix the main water pipe 1 at the window position, preventing the water pipe from moving under the action of water pressure, and ensuring the stability and safety of the entire fire extinguishing operation. By rotating the screw 7 through the force-applying rod 8, the torque generated can firmly fix the water pipe to the window. To ensure that the fixing rod and the screw 7 do not deform under the action of high-pressure water flow, it is recommended to use high-strength steel or aluminum alloy materials, which can provide sufficient strength and corrosion resistance.

[0038] This also includes multiple branch pipes 4, each with a drain hole 10. Two sealing caps 11 are provided, covering the unconnected ends of two branch pipes 3. The drain hole 10 design of the branch pipes helps to evenly distribute the water flow, ensuring the spray angle and distribution range of the water flow. The sealing caps 11 can easily seal the ports of the branch pipes 3, preventing water leakage when not connected, and can be quickly disassembled for the addition of branch pipes 3. The two branch pipes on the outermost edge of the multiple branch pipes 4 have drain holes 10 angled outwards. The drain holes 10 of the remaining branch pipes 4 extend perpendicularly to the ground and are arranged horizontally. The water flow is distributed in a fan shape through the water spray holes of the multiple branch pipes 4, ensuring that fires in each direction can be effectively extinguished. This design is particularly suitable for extinguishing large-area exterior facade fires, quickly suppressing the fire source and controlling its spread.

[0039] It should be noted that when using the water gun designed for extinguishing the vertical spread of fire on the exterior facade of a multi-story building, once the fire on the ground floor begins to spread upwards through the facade, firefighters need to connect the water supply hose to the main water pipe 1, and then carry the main water pipe 1 to the higher floors where the fire has not yet spread. At this time, depending on the size and width of the high-rise window or the fire intensity, the sealing caps 11 of the unconnected ends of the two branch pipes 3 can be removed, and additional branch pipes 3 can be added. After the additional branch pipes 3 are completed, the sealing caps 11 are clamped, the baffle 9 is placed on the edge of the window, and the force rod 8 is manually rotated. The force rod 8 receives the applied force and drives the screw 7 to rotate. The torque generated by the rotation of the screw 7 begins to move towards the first fixing rod 5. After the end of the second fixing rod 6 contacts the wall of the window and abuts against the wall, the main water pipe 1 is fixed to the window. Finally, the water flow is connected, and the water flows through the main water pipe 1 into the tee connector 2. From the tee connector 2, it is distributed to multiple branch pipes 4 of the branch pipe 3. At this time, the water sprayed from the drain holes 10 of the branch pipes will spread in a fan shape, extinguishing the fire on the floors below. During this process, firefighters only need to secure the main water pipe 1 to the window before they can evacuate to a safe area, avoiding the situation where the fire spreads too quickly and they are unable to evacuate in time if they are holding the water hose.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
