Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment, and in particular to a fire extinguishing and smoke exhaust water gun assembly for high-rise buildings. Background Technology

[0002] Fire hoses are water-spraying tools used for extinguishing fires. When connected to a fire hose, they can spray a dense and powerful stream of water, offering advantages such as long range and large water volume. Based on the different jet patterns and characteristics, fire hoses can be classified as straight-stream hoses, spray hoses, and multi-purpose hoses. Before using a fire hose, open the fire hydrant door, remove the hose and hose, and check the hose and connectors for damage. If any are damaged, do not use the hose. Lay the hose towards the fire, taking care to avoid twisting. Connect the hose to the fire hydrant, accurately inserting the connector into the groove and tightening it clockwise. After connection, at least two operators should firmly grip the hose and aim it at the fire source (never aim at people to avoid injury from high pressure). Another operator should slowly open the fire hydrant valve to its maximum, spraying at the base of the fire until it is completely extinguished.

[0003] However, existing high-rise fire hoses often encounter the following problems in use: Different high-rise fire scenarios present numerous complex situations, such as varying sizes of the fire-affected spaces, different types of combustible materials, and vastly different directions and speeds of fire spread. In such cases, the requirements for the angle and spray range of the water flow during firefighting differ. For example, in confined and complex indoor fire scenarios, the sprinkler head may need to precisely adjust the water flow angle to accurately spray water into narrow corners or concealed fire points. Due to limited space, the spray range does not need to be excessively large, but precise control is essential. In large warehouse fire scenarios, the fire area is often large and the fire spreads rapidly. This requires the sprinkler head to have a sufficiently large spray range to cover a large area, and it may need to spray from different angles to adapt to different fire directions. However, traditional sprinkler heads, due to their structural and functional limitations, often lack flexibility. They can mostly only operate at fixed angles and relatively fixed spray ranges, making it difficult to adjust flexibly according to different fire scenarios. Therefore, they may not achieve the ideal firefighting effect when dealing with complex and changing fire situations. Utility Model Content

[0004] The main objective of this invention is to provide a fire extinguishing and smoke extraction water gun assembly for high-rise buildings, so as to effectively solve the problem mentioned in the background art that the existing water guns cannot meet the needs of fire extinguishing in high-rise environments, where different stages of fire require the use of water flow at different angles for effective extinguishing.

[0037] 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.

[0038] 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.

[0039] like Figure 1-5 As shown, a fire extinguishing and smoke extraction water gun assembly for high-rise buildings includes: an acute-angle nozzle 1, a main pipe 2, a right-angle nozzle 3, an extension rod 4, and a sealing joint 53. Each of the acute-angle nozzle 1, main pipe 2, right-angle nozzle 3, and extension rod 4 has a corresponding sealing joint 53 installed at one end. The main pipe 2 can be arbitrarily connected to the sealing joints 53 of the acute-angle nozzle 1, right-angle nozzle 3, and extension rod 4. The extension rod 4 can be arbitrarily connected to the sealing joints 53 of the acute-angle nozzle 1, right-angle nozzle 3, and main pipe 2.

[0040] In this invention, to quickly control the fire, an acute-angle nozzle 1 is designed, comprising: one end of an acute-angle tube 11 connected to a corresponding sealing joint 53; a water gun nozzle 12 installed at the other end of the acute-angle tube 11; and a first window breaker 13 installed at the end of the water gun nozzle 12. The acute-angle nozzle 1 is designed to achieve rapid high-angle water spraying at a fire scene. Due to its 80-degree angle, it ensures that the sprayed water flow accurately reaches the ceiling of a high-rise fire. This design ensures that the water flow reflects and diffuses at a high angle, providing wider fire extinguishing coverage, especially suitable for high-rise building fires. Installing a window breaker at the end of the acute-angle nozzle 1 allows for rapid window breaking and quick access to water flow during a fire, thereby improving fire extinguishing efficiency. The window breaker design takes into account scenarios requiring rapid rescue and fire extinguishing in emergency situations.

[0041] In this invention, to achieve smoke extraction, a right-angle nozzle 3 is designed, which also includes: one end of a guide pipe 31 connected to a corresponding sealing joint 53, one end of a U-shaped pipe 32 connected to the other end of the guide pipe 31, an atomizing nozzle 33 installed at the other end of the U-shaped pipe 32, and a second window breaker 34 installed at the end of the atomizing nozzle 33. The right-angle nozzle 3 is suitable for situations requiring water mist spraying towards windows or lower angles, especially near windows in high-rise buildings. The structure of the U-shaped pipe 32 allows the U-shaped opening to be easily fixed into the windowsill, enabling the water mist to directly enter the room. According to Bernoulli's principle, pressure decreases where fluid velocity increases, thus creating a low-pressure zone in the water mist spray area. Surrounding air is drawn into this low-pressure zone, creating negative pressure. This negative pressure causes indoor air to flow in the direction of the water jet, carrying smoke and heat outdoors, achieving smoke extraction. The right-angle nozzle 3 is also equipped with a second window breaker 34, making the design more multifunctional and enhancing the flexibility of on-site operation.

[0042] In this invention, the main pipe 2 also includes: a straight water supply pipe 21; a main handle 22 installed at one end of the water supply pipe 21; a horizontal handle 23 installed on the outer surface of the main handle 22; and a diagonal handle 24 installed on the side wheel surface of the main handle 22. The pipe section, as the core of the entire system, connects the various nozzles and the extension rod 4. The design of the main handle 22, the horizontal handle 23, and the diagonal handle 24 makes operation more comfortable and stable, especially in high-rise fires where it may be necessary to hold the nozzle for extended periods or adjust the spray angle. The design of these handles helps firefighters operate the water gun flexibly, especially maintaining control under high pressure.

[0043] In this embodiment, to enable the various components to be arbitrarily and quickly inserted, a sealing connector 53 is designed, including: an infusion channel 52 opened within the connector body 51, one end of the sealing connector 53 inserted into the infusion channel, and a retaining spring 54 sleeved on the port of the inserted end of the sealing connector 53, the retaining spring 54 being located within the infusion channel 52. The retaining spring 54 is typically elastic and can deform within a certain range. Taking the water pipe 21 as an example, in the quick-connect connector for the water pipe 21, the cylindrical groove on the retaining spring 54 body divides the retaining spring 54 body into several opening and closing pieces. When the water pipe 21 is inserted into the connector body and force is applied to the inside of the connector body, the opening and closing pieces expand outward under the pressure of the water pipe body, and the protrusions in the opening and closing pieces engage in the second groove in the connector body, thereby realizing the function of locking the water pipe 21.

[0044] In the above embodiments, the working principle of the retaining spring 54 is based on its elastic deformation and recovery capability. In the quick-connect water pipe connector, when an external force is applied to the water pipe towards the outside of the connector body, the water pipe drives the retaining spring 54 to move towards the outside of the connector body, and the boss in the retaining spring 54 moves from the second groove to the first groove of the connector body. Since the radial distance of the first groove is less than the radial distance of the second groove, the engaging piece in the retaining spring 54 retracts towards the water pipe body, further clamping the water pipe body, making the connection between the connector and the water pipe stable, and the water pipe body is not easily pulled out of the connector body. The annular spring piece of the inner ring of the annular retaining spring 54 is inclined downward, allowing the pipe to be easily inserted. When the pipe is to be pulled out upward, the outer wall of the pipe is locked by the annular spring piece. At this time, by a specific operation, i.e., rotating the pipe body while pulling it outward, the annular retaining spring 54 is released, thereby realizing the operation of pulling out the pipe.

[0045] It should be noted that, in the case of a high-rise building fire extinguishing and smoke extraction water gun assembly designed in this utility model, firefighters only need to climb to the floor below the fire floor in the event of a high-rise fire. They can then quickly assemble the assembly by directly inserting the water supply end of the water pipe 21 into the sealing joint 53 of the acute-angle nozzle 1, as needed. If the window sill of the fire floor is too high, an extension rod 4 can be installed between the acute-angle nozzle 1 and the water supply pipe 21. Afterwards, the firefighter holds the main handle 22 and uses the first window breaker 13 of the acute-angle nozzle 1 to break the window glass, connecting the water flow. The water pipe will guide the water flow through the bottom end of the main handle 22 to the water gun nozzle 12 for high-angle water spraying. The acute-angle pipe 11 has an angle of 80 degrees, which can easily spray the water stream to the ceiling of the upper floor, achieving the conditions for transitional water spraying. High-angle water spraying towards the ceiling is employed. High-angle water spraying maximizes the spread and settling of water impacting the ceiling, while also achieving optimal atomization, thus covering the fire area to the greatest extent. Water spraying lowers indoor temperature, slowing the spread of fire and creating more favorable conditions for interior attack. Once the fire is under control, the extension rod 4 is inserted into the sealing joint 53 of the right-angle nozzle 3, and finally, the main pipe 2 is connected to the sealing joint 53 of the extension rod 4, completing the assembly of the right-angle nozzle 3. Finally, the atomizing nozzle 33 of the right-angle nozzle 3 is used to directly spray water mist into the building at an angle flush with the window. When the fire hose sprays water mist, the spray creates airflow and negative pressure. This negative pressure causes indoor air to flow in the direction of the water spray, carrying smoke and heat outdoors, achieving smoke extraction. Simultaneously, the water mist itself absorbs and settles smoke and dust, further purifying the air.

[0046] 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.
