Description

Technical Field

[0001] The invention belongs to the technical field of fire fighting equipment, and in particular relates to a smoke exhaust water gun. Background Art

[0002] When a building fire occurs, the building structure and form are diverse, and the internal divisions are complex. After the fire breaks out, it is easy to cause large-scale smoke filling, which brings difficulties to rescue and fire fighting, especially when the combustibles generate a lot of heat and smoke during the combustion process. The heat will spread outward in the form of heat conduction, heat radiation and heat convection. As a carrier of material transfer during combustion, the temperature of fire smoke can often reach 300-800℃, which will carry a lot of heat out of the combustion area and spread to other parts of the building along the doors, windows, corridors, stairs, pipes, holes, etc. of the building, posing a serious threat to the trapped and the firefighters entering the building. In addition, in high-rise buildings, the high-temperature smoke generated by the fire will quickly spread to the upper floors along the interior of the building under the dual effects of buoyancy and chimney effect, making it increasingly difficult to intercept and control the fire, and it is very easy to form a three-dimensional fire.

[0003] Experiments have shown that people are in danger of death if they come into contact with thick smoke for 4 to 5 minutes. This is because the solid and liquid particles in the smoke scatter and absorb light, so that only a portion of the light can pass through the smoke, causing visibility at the fire scene to be greatly reduced. Due to the light-dimming effect of the smoke, the fire smoke greatly reduces people's ability to identify targets, and weakens the role of accident lighting and evacuation signs. The inability to quickly exhaust smoke in the fire scene increases the difficulty of rescue for firefighters, and greatly reduces the efficiency of firefighting and rescue.

[0004] The existing water-driven smoke exhaust method has been used for decades, but there are still the following problems: firefighters must operate indoors. First, they need to extinguish the fire indoors, and then spray a large amount of water mist from a nearby window to exhaust the thick smoke and toxic gases generated indoors out of the window. This operation method poses a great threat to the personal safety of firefighters. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a smoke exhaust water gun, which forms a placement groove that can be hung on the windowsill through a first U-shaped water pipe connected to the water pipe and a water pipe hook, so that firefighters can place the water gun outdoors at the window and directly start the water gun to spray a large amount of water mist outward, thereby forming a negative pressure to discharge the thick smoke and a large amount of toxic gases generated by indoor burning out of the window, thereby solving the problem that indoor operation may pose a great threat to the personal safety of firefighters.

[0023] The following embodiments of the present invention are described in detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a smoke exhaust water gun comprises a water gun body 1, one end of the water gun body 1 is connected to a water gun connector 2, the other end of the water gun body 1 is connected to a water pipe 3, the top of the water pipe 3 is connected to a first U-shaped water pipe 4, the U-shaped bottom of the first U-shaped water pipe 4 is cross-connected with a second U-shaped water pipe 5, outlets of the first U-shaped water pipe 4 and the second U-shaped water pipe 5 are both provided with water outlet nozzles 6, a water pipe hook 7 is provided on the outside of the connection between the first U-shaped water pipe 4 and the water pipe 3, and a crushing end 8 is provided on the outside of the cross intersection of the first U-shaped water pipe 4 and the second U-shaped water pipe 5.

[0025] Specifically, a smoke exhaust water gun can efficiently perform smoke dispersal and fire extinguishing operations. The water gun body 1 is the core supporting structure of the entire smoke exhaust water gun and is made of high-strength lightweight materials to ensure stability and durability during operation. Its appearance design conforms to the principles of ergonomics, making it convenient for firefighters to hold it for a long time without feeling tired. The water gun connector 2 is installed at one end of the water gun body 1 and adopts a standard threaded interface, which is convenient for quick connection with the fire water source. It is also convenient to replace water gun heads of different specifications or types to meet the needs of different scenarios. At the other end, the water pipe 3 is connected to the water gun body 1 in the form of a high-strength hose or a hard pipe, which is responsible for transporting water to the front end of the water gun.

[0026] The top of the water pipe 3 is connected to the first U-shaped water pipe 4, which not only optimizes the water flow distribution, but also increases the spray range. The U-shaped bottom of the first U-shaped water pipe 4 is designed as a cross-shaped structure, which is connected to the second U-shaped water pipe 5 in all directions. Such a layout allows the water flow to be evenly distributed in multiple directions, improving the efficiency of smoke exhaust and fire extinguishing. A water outlet nozzle 6 is configured at each outlet of the first U-shaped water pipe 4 and the second U-shaped water pipe 5. The water outlet nozzle 6 is equipped with a small nozzle inside, which can produce high-pressure fine mist, which can effectively disperse smoke, reduce water waste, and protect on-site equipment.

[0027] In order to enhance the functionality and practicality of the water gun, a water pipe hook 7 is cleverly arranged on the outside of the connection between the first U-shaped water pipe 4 and the water pipe 3. This hook can be used as a temporary hanging point to facilitate firefighters to flexibly operate the water gun in a complex environment, and can also be used as a demolition tool to assist in clearing obstacles and opening up a channel for rescue operations.

[0028] A crushing end 8 is installed outside the cross intersection of the first U-shaped water pipe 4 and the second U-shaped water pipe 5. The crushing end 8 is made of hard alloy, sharp and strong, and can easily penetrate a thick smoke layer or crush obstacles, opening a path for the water flow to reach the fire source directly, greatly improving the efficiency of smoke exhaust and fire extinguishing.

[0029] When a fire occurs, the firefighter holds the water gun body 1, connects the water pipe 3 and the first U-shaped water pipe 4 according to the actual situation, extends it to the window, breaks the window with the breaking end 8, hangs it on the windowsill through the bend where the first U-shaped water pipe 4 and the water pipe 3 are combined, and starts the water gun so that the water nozzle 6 forms a large amount of water mist sprayed out of the window, forming a negative pressure to discharge the indoor burning smoke and a large amount of toxic gases out of the window. The firefighters can achieve the smoke exhaust and fire extinguishing effect without entering the room.

[0030] This smoke exhaust water gun achieves efficient, flexible and multifunctional smoke exhaust and fire extinguishing effects through its unique design and sophisticated layout. It is an indispensable and important tool in firefighting work.

[0031] Combination Figure 4 , Figure 5 and Figure 6 As shown, the water outlet end of the water pipe 3 is provided with a connector 31, the inner wall of the connector 31 is provided with an internal thread, the water outlet end of the water pipe 3 is threadedly connected to the bottom of the first U-shaped water pipe 4, the water inlet end of the water pipe 3 is provided with an external thread, and the water inlet end of the water pipe 3 is threadedly connected to the water gun connector 2.

[0032] Specifically, a connector 31 is designed at the water outlet of the water pipe 3, which not only enhances the connection stability between the water pipe and the subsequent pipeline, but also ensures the smooth flow of water during the transmission process. The inner wall of the connector 31 is provided with internal threads, which are processed according to strict tolerance standards to ensure that it can be tightly and firmly connected with the bottom of the first U-shaped water pipe 4. The bottom of the first U-shaped water pipe 4 is also designed with matching external threads. When the two are tightened together by rotation, a strict waterproof barrier can be formed to effectively prevent high-pressure water from leaking at the connection point and ensure a continuous and stable supply of water.

[0033] At the other end of the water pipe 3, i.e. the water inlet end, an external thread is provided to achieve seamless connection with the water gun connector 2. The water gun connector 2 is also designed with an internal thread that matches the external thread of the water inlet end of the water pipe 3. The two can be tightly connected together by a simple rotation operation. Not only is the operation simple and fast, but the connection is also reliable and can withstand the high-pressure water flow from the water source, ensuring the normal operation of the entire smoke exhaust water gun system.

[0034] It is worth noting that both the connection between the connector 31 and the first U-shaped water pipe 4 and the connection between the water inlet end of the water pipe 3 and the water gun connector 2 use standardized thread specifications. This not only improves the interchangeability between the various components of the smoke exhaust water gun, allowing firefighters to quickly replace damaged components in an emergency, but also facilitates daily maintenance and reduces the cost of use.

[0035] In order to ensure the sealing and durability of the connection, the connector 31 and the water inlet end of the water pipe 3 are treated with special anti-corrosion technology during the processing to enhance their corrosion resistance and extend their service life.

[0036] Combination Figure 2 , Figure 3 and Figure 4 As shown, the water pipe 3 is formed by splicing together multiple sections of water pipes.

[0037] Specifically, the water pipe 3, as an important component of the smoke exhaust water gun, fully considers the flexibility and convenience in actual use. To achieve this goal, the water pipe 3 is designed to be spliced ​​by multiple sections of water pipes. Each section of the water pipe is made of high-strength, corrosion-resistant materials to ensure stable performance under high-pressure water flow and complex environments. These water pipes not only have sufficient strength and toughness to withstand the impact of water flow, but also have good wear resistance, which extends the service life of the water pipe.

[0038] In terms of splicing, both ends of each water pipe are designed with standardized connection interfaces. These interfaces can be either threaded interfaces or quick-plug interfaces, depending on the needs of the actual application scenario. The threaded interface is connected by rotating and tightening, which has the advantages of firm connection and not easy to loosen; while the quick-plug interface is convenient for quickly replacing or adjusting the water pipe in an emergency, which improves the convenience of operation.

[0039] The design of splicing multiple sections of water pipes not only improves the flexibility of the water pipes, enabling them to adjust their length and shape as needed to adapt to different working environments and space constraints. At the same time, this design also facilitates the transportation and storage of water pipes. During transportation, the water pipes can be split into multiple sections, reducing the volume and weight, making them easier to carry and transport; during storage, multiple sections of water pipes can also be neatly stacked or hung to save space.

[0040] Combination Figure 4 , Figure 5 and Figure 6 As shown, the water pipe hook 7 is a semicircular structure, one side of the water pipe hook 7 remains parallel to the water pipe 3 and forms a placement groove 9 that can hang on the windowsill, and auxiliary support rods 13 are arranged between the other side of the water pipe hook 7 and the outer walls of the second U-shaped water pipe 5 on both sides.

[0041] Furthermore, the water pipe hook 7 not only enhances the functionality of the water gun, but also greatly improves its practical value. The water pipe hook 7 is a semicircular structure, which not only makes its appearance more streamlined and more ergonomic, but also ensures its stability and reliability when hanging on a support such as a window sill. One side of the water pipe hook 7 is parallel to the water pipe 3, and a placement groove 9 that can hang on the window sill is cleverly formed.

[0042] Auxiliary support rods 13 are arranged between the other side of the water pipe hook 7 and the outer walls of the second U-shaped water pipe 5 on both sides. These auxiliary support rods 13 not only play a role in reinforcing the hook structure, making it more durable, but also improve the stability of the hook during use. The connection parts of the auxiliary support rods 13, the hook and the pipe are all made of high-strength materials and are processed by precision machining and welding to ensure the firmness and reliability of the connection.

[0043] Combination Figure 4 , Figure 5 and Figure 6 As shown, a cooling terminal 10 is provided on the back of each water outlet nozzle 6, and a protective cover 14 is provided on all cooling terminals 10. A plug-in connection structure is adopted between the cooling terminal 10 and the protective cover 14.

[0044] Specifically, each water outlet nozzle 6 is cleverly designed with a cooling terminal 10 on the back to effectively disperse and reduce the heat generated during the operation of the nozzle, ensuring that the device can continue to operate efficiently and stably. These cooling terminals 10 are not only made of high thermal conductivity materials to accelerate the conduction and dissipation of heat, but also their shape and layout are carefully calculated to maximize the heat dissipation area and improve the heat dissipation efficiency.

[0045] In order to ensure that the cooling end 10 is protected from pollution and physical damage from the external environment during non-use or maintenance, all cooling ends 10 are equipped with protective covers 14. These protective covers 14 not only have the basic protection functions of dust and water resistance, but also can isolate the influence of temperature changes on the internal precision structure of the cooling end to a certain extent, thereby extending its service life.

[0046] The connection between the cooling terminal 10 and the protective cover 14 adopts an innovative plug-in structure, which greatly simplifies the installation and removal process, allowing users to quickly and easily complete the operation when cleaning, inspecting or replacing the cooling terminal, without using complex tools or additional auxiliary equipment. The plug-in structure also ensures the tightness and stability of the connection part, preventing loosening or falling off due to vibration or external force during use, further improving the overall safety and reliability of the system.

[0047] In addition, the design of the plug-in connection structure also takes into account details that are easy to identify and operate. For example, the protective cover may be provided with eye-catching logos or color codes so that users can quickly and accurately find and operate the corresponding protective cover. At the same time, the plug-in interface may adopt anti-slip and self-locking designs to ensure that it will not be easily separated due to misoperation in the connected state, which provides great convenience for users.

[0048] Combination Figure 2 , Figure 3 and Figure 4 As shown, all water outlet nozzles 6 are atomizing nozzles.

[0049] Furthermore, all water outlet nozzles 6 adopt atomizing nozzles, which not only greatly improves the functionality and efficiency of the smoke exhaust water gun, but also reflects the efficient use of water resources and in-depth consideration of the impact on the environment. The atomizing nozzle can disperse the water flow into countless fine water mist particles through its internal precise atomization structure. These tiny particles not only have a larger surface area, but can also more effectively contact and adsorb smoke particles in the air, thereby accelerating the dilution and dissipation of smoke and improving the smoke exhaust effect. At the same time, because the water mist particles are extremely small, they can evaporate quickly, reducing the impact of humidity on the on-site environment and avoiding secondary damage caused by large amounts of water flow.

[0050] The use of atomizing nozzles also means that a wider area can be covered at the same water flow rate, improving the efficiency of water resource utilization. Compared with traditional water spraying methods, atomizing nozzles can achieve the same smoke exhaust effect with less water, which is undoubtedly a more environmentally friendly and sustainable choice for the current situation of increasingly tight water resources.

[0051] Combination Figure 1 , Figure 2 and Figure 3 As shown, a water gun handle 11 for easy holding is arranged on one side of the water gun body 1, and a water gun control valve 12 for controlling water flow is arranged on the other side of the water gun body 1.

[0052] Furthermore, the water gun body 1, as the core component of the smoke exhaust water gun, fully integrates ergonomic principles and actual operation requirements, aiming to provide firefighters with the most convenient and efficient use experience in emergency situations. On one side of the water gun body 1, a water gun grip 11 is provided for easy gripping. On the other side opposite to the water gun grip 11, a water gun control valve 12 for controlling the water flow is provided. This control valve is a key component in the operation of the smoke exhaust water gun, which allows firefighters to accurately adjust the switch, flow rate and spray mode of the water flow according to the fire situation and smoke exhaust requirements.

[0053] It is worth noting that high-strength connection methods and sealing designs are used between the water gun body 1, the water gun handle 11 and the water gun control valve 12 to ensure that under high-pressure water flow, the entire water gun system can maintain a tight and stable connection to prevent water leakage or loose components, thereby ensuring efficient and safe use of the smoke exhaust water gun.

[0054] Combination Figure 1 , Figure 2 and Figure 3 As shown, the surface of the water gun handle 11 is provided with anti-slip textures.

[0055] Specifically, the water gun handle 11 is not only related to the comfort and stability of firefighters during operation, but also directly related to the safety and efficiency of operation. Anti-slip patterns are cleverly set on the surface of the water gun handle 11, which not only improves the stability of the grip, but also further enhances the firefighters' confidence in operation in emergency situations. The design of the anti-slip patterns has been carefully calculated and tested, and its shape, depth and distribution have been optimized to ensure the best anti-slip effect in various environments. These patterns usually have an uneven shape, which not only helps to increase the friction between the hand and the grip to prevent slipping in wet or slippery conditions, but also allows firefighters to feel obvious tactile feedback when holding, so as to control the water gun more accurately.

[0056] When a fire occurs, the firefighter holds the water gun handle 11 on the water gun body 1, connects the water pipe and the first U-shaped water pipe 4 according to the actual situation, extends it to the window, breaks the window with the broken end 8, hangs it on the windowsill through the placement groove 9 formed by the water pipe hook 7 and the water pipe 3, starts the water gun control valve 12, and the water nozzle 6 forms a large amount of water mist sprayed out of the window, forming a negative pressure to discharge the indoor burning smoke and a large amount of toxic gases out of the window. Firefighters can achieve the smoke exhaust and fire extinguishing effect without entering the room.

[0057] The anti-slip pattern also has a certain aesthetic and recognition. It not only improves the overall visual effect of the water gun handle, but also enables firefighters to quickly identify and accurately hold the handle in an emergency, reducing the time wasted on finding the grip position. It is usually made of wear-resistant and corrosion-resistant materials to ensure that it can maintain clear patterns and good anti-slip performance under long-term use and frequent operation. At the same time, the processing of these patterns has also been finely polished and processed to avoid injuries to firefighters' hands due to sharp edges or uneven surfaces.

[0058] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
