[0035] The embodiments of the present invention are described in detail below.

[0036] Please refer to Figures 1-6, the embodiment provides a portable fire-fighting equipment for pumping flue gas, including a fan 1, two sections of air pipe 2 connected to the output and input of the fan 1 respectively, and a mobile power supply box 3 providing power supply for the fan 1 through the power supply line 4. The design of the mobile power supply box 3 makes the whole equipment more portable and flexible. In the fire scene, the power supply box 3 can be quickly moved according to the needs to provide power support for the fan 1. This design greatly improves the applicability and practicality of the equipment. The output and input of the fan 1 are provided with a ring-shaped and radially outwardly expanding flange 101, a plurality of jack 102 are arranged in a ring array on the flange 101, and the design of the flange 101 provides the basic structure for the connection of the fan 1 and the air pipe 2, and the radially outwardly expanding shape increases the connection area and enhances the stability of the connection. The arrangement of the jack 102 provides a positioning point and a fixing point for the subsequent bolt 203 connection, ensuring the accurate alignment and firm connection between the air pipe 2 and the fan 1.

[0037] In order to improve safety, an explosion-proof relay can be arranged in the fan 1. This design provides additional safety protection for potential dangerous environments such as gas leakage. The explosion-proof relay can effectively prevent explosion caused by sparks or arcs inside electrical equipment, ensuring the safe operation of the equipment in flammable and explosive environments. In the fire scene, especially when dealing with fires in chemical plants, oil depots or gas stations, the equipment must have high explosion-proof performance to prevent secondary disasters;

[0038] The connection between the air pipe 2 and the fan 1 is provided with a connecting ring 201, which is in sealing contact with the flange 101. One side of the connecting ring 201 is provided with an axially outwardly protruding butt ring 202, which is connected with the air pipe 2 in a socket joint. The other side of the connecting ring 201 is provided with a plurality of bolts 203 corresponding to each jack 102 and inserted and matched. The design of the connecting ring 201 realizes the quick connection and sealing between the air pipe 2 and the fan 1. The socket joint of the butt ring 202 and the air pipe 2 ensures the stable connection between the air pipe 2 and the connecting ring 201, and the cooperation of the bolt 203 and the jack 102 realizes the accurate positioning and fixing between the fan 1 and the air pipe 2. This design makes the installation and disassembly of the air pipe 2 simple and fast;

[0039] The connecting ring 201 is rotationally connected with a plurality of plectra 204 away from one side of the fan 1, and the end of the plectra 204 is fixedly provided with a hook 205 extending to the flange 101, and the plectra 204 and the hook 205 form a V-shaped structure, when the plectra 204 is pushed to the bottom in an arbitrary clockwise direction, the flange 101 and the edge of the connecting ring 201 in contact with each other will be jointly inserted into the V-shaped structure, and the V-shaped structure formed by the plectra 204 and the hook 205 is the key to realize the tight sealing between the fan 1 and the air pipe 2. When the plectra 204 is pushed, the V-shaped structure will be inserted into the edge of the flange 101 and the connecting ring 201 to form a tight sealing layer. This design not only enhances the sealing of the connection, but also makes it easy to remove the seal by reversing the plectra 204 without using any tools.

[0040] In summary, the patent of the application realizes a portable fire-fighting equipment for pumping flue gas through the design of the flange 101 at the output end and the input end of the fan 1, the design of the connecting ring 201 of the air pipe 2, the V-shaped structure design of the plectra 204 and the hook 205, and the design of the mobile power supply box 3. This equipment not only has stable connection and good sealing, but also is very simple and fast to install and disassemble, greatly improving the efficiency and safety of fire-fighting work.

[0041] In use, first, the connecting ring 201 of the air pipe 2 is aligned with the flange 101 of the fan 1, the pins 203 on the connecting ring 201 correspond to the insertion holes 102 on the flange 101, then the connecting ring 201 is pushed towards the flange 101 until the pins 203 are completely inserted into the insertion holes 102 to achieve preliminary connection, then the plectra 204 on the connecting ring 201 are pushed to make the V-shaped structure formed by the plectra 204 and the hook 205 jointly insert the flange 101 and the edge of the connecting ring 201 into the V-shaped structure to form a tight sealing layer, then the mobile power supply box 3 is connected with the fan 1 through the power supply line 4 to ensure normal power supply, then the fan 1 is started to pump flue gas, when the air pipe 2 needs to be disassembled, the plectra 204 are pushed in the opposite direction to make the flange 101 and the edge of the connecting ring 201 move out of the V-shaped structure formed by the plectra 204 and the hook 205, then the connecting ring 201 is pulled out, this disassembly method is also simple and fast without using tools.

[0042] In some embodiments, as shown in FIG. 2 or FIG. 4, the air pipe 2 is a telescopic adjustable bellows with good flexibility and telescopic adjustment. The telescopic adjustable bellows design enables the air pipe 2 to adjust the length according to the actual use scene. In the fire scene, there are often various complex terrains and obstacles. The traditional fixed length air pipe 2 may not meet all needs, while the telescopic adjustment of the bellows greatly enhances the adaptability of the equipment, which can easily bypass obstacles and reach the position where smoke needs to be pumped. Moreover, the flexibility of the bellows makes it easier to bend and shape during installation without the need for additional tools or complex operation steps.

[0043] Preferably, as shown in FIGS. 1-3, the top of the fan 1 and the power supply box 3 is respectively provided with a pipe rack 103 and a wire rack 301. Both the pipe rack 103 and the wire rack 301 are composed of at least three vertical columns arranged vertically, forming a stable support structure. The air pipe 2 can be wrapped on the pipe rack 103 after being shortened to the shortest length, realizing the convenient storage of the air pipe 2. The power supply wire 4 can be wound and stored on the wire rack 301, ensuring the neatness and order of the power supply wire 4. The design of the pipe rack 103 and the wire rack 301 provides a special storage space for the air pipe 2 and the power supply wire 4. When the equipment is not in use, the air pipe 2 can be shortened to the shortest length and wrapped on the pipe rack 103, and the power supply wire 4 can be wound on the wire rack 301, which greatly reduces the occupied space of the equipment, making it more portable and storage-friendly. For portable fire-fighting equipment that needs to be moved frequently and used in different places, this design greatly improves the portability and practicality of the equipment.

[0044] In some embodiments, as shown in FIGS. 7-9, the air pipe 2 includes several pipe bodies made of flexible windproof cloth 207 and annular skeletons 206 arranged between adjacent pipe bodies. The annular skeletons 206 are used to maintain the basic shape of the air pipe 2, and when the air pipe 2 needs to be stored, only the concentric stacking of the annular skeletons 206 is required, which is very convenient. The flexible windproof cloth 207, as the main part of the air pipe 2, can be easily folded and bent, realizing the flexible extension and bending of the air pipe 2. The annular skeleton 206 is a hollow metal ring structure with a ring-shaped gap 2061 on the inside. The end of the flexible windproof cloth 207 on both sides of the annular skeleton 206 is inserted into the gap 2061 and reversely rolled inside the annular skeleton 206, realizing the connection between the annular skeleton 206 and the flexible windproof cloth 207. Moreover, a metal heat dissipation ring 209 is embedded in the gap 2061. The heat dissipation ring 209 is interference fitted between the rolled ends of adjacent flexible windproof cloth 207, with the inner circle of the heat dissipation ring 209 remaining in the pipe body and the outer circle extending into the annular skeleton 206.

[0045] Specifically, the design of the annular skeleton 206 not only maintains the basic shape of the air pipe 2, but also makes the air pipe 2 extremely convenient to store. By simply stacking the annular skeletons 206 concentrically, the occupied space of the air pipe 2 can be greatly reduced, facilitating carrying and storage. In the fire scene, this design enables firefighters to quickly deploy the air pipe 2, improving response speed. The flexible windproof cloth 207 as the main part of the air pipe 2 has excellent flexibility and scalability. This enables the air pipe 2 to be easily folded and bent according to actual needs, adapting to various complex terrains and obstacles, and ensuring smooth smoke extraction. The design of the split 2061 on the inner side of the annular skeleton 206, and the reverse rolling of the end of the flexible windproof cloth 207 in the split 2061, realizes the stable connection between the annular skeleton 206 and the flexible windproof cloth 207. This connection not only enhances the structural strength of the air pipe 2, but also improves its durability, ensuring that the air pipe 2 is not easily damaged during long-term use, and is also very simple to disassemble and assemble. When transporting high-temperature smoke, the heat dissipation ring 209 can quickly transfer the heat in the air pipe 2 to the annular skeleton 206 made of metal, and then to the outside through the annular skeleton 206, avoiding excessive heat accumulation in the air pipe 2. This design effectively reduces the working temperature of the air pipe 2, improves the safety of the equipment, and prevents potential risks caused by high temperature. Moreover, the presence of the heat dissipation ring 209 can also make the flexible windproof cloth 207 inserted into the split 2061 tighter, thereby improving the connection strength between the flexible windproof cloth 207 and the annular skeleton 206. In the above structure, the connection between the annular skeleton 206 and the flexible windproof cloth 207 is simple and effective, without the need for complex installation steps or professional tools. Only by slightly opening the split 2061 on the annular skeleton 206 can the flexible windproof cloth 207 be quickly inserted or extracted. At the same time, the embedding of the heat dissipation ring 209 does not increase the difficulty of installation, but rather reduces the maintenance frequency of the air pipe 2 due to high temperature, thereby reducing the use cost.

[0046] Preferably, as shown in FIGS. 7-8, the annular framework 206 is provided with a clamp 208, which is used to tighten the split 2061 on the inner side of the annular framework 206, thereby clamping the flexible windproof cloth 207 and the heat dissipation ring 209 inserted into the split 2061. This clamping action effectively prevents the flexible windproof cloth 207 from being pulled out of the split 2061 during use due to external force or internal smoke pressure, thereby enhancing the structural stability and connection reliability of the air duct 2. The clamp 208 not only clamps the flexible windproof cloth 207, but also ensures that the heat dissipation ring 209 is firmly embedded in the split 2061, which ensures that the heat dissipation ring 209 can effectively transfer the heat in the air duct 2 to the annular framework 206 and dissipate to the outside through the annular framework 206, thereby avoiding excessive heat accumulation in the air duct 2 and improving the safety of the equipment. In addition, the design of the clamp 208 makes the connection and disconnection process of the flexible windproof cloth 207 and the annular framework 206 more convenient. During installation, only the end of the flexible windproof cloth 207 needs to be inserted into the split 2061, and then the clamp 208 needs to be tightened. During disassembly, only the clamp 208 needs to be loosened, and the flexible windproof cloth 207 can be easily pulled out of the split 2061.

[0047] In some embodiments, as shown in FIG. 3, the top of the fan 1 is provided with a lifting ring 104, which is used to connect with the lifting equipment. In the fire scene, the fan 1 often needs to be installed at a specific height or position according to the actual situation, so as to more effectively pump smoke. The design of the lifting ring 104 makes the fan 1 can be easily lifted and fixed at the required position by the lifting equipment.

[0048] In some embodiments, as shown in FIG. 3, the bottom of the fan 1 is provided with a base 105, the vertical section of the base 105 is L-shaped, and the base 105 has a trapezoidal structure with a narrow top and a wide bottom. The trapezoidal structure makes the base 105 more stable when placed and less likely to fall over.

[0049] In some embodiments, as shown in FIGS. 1-3, the bottom of the fan 1 and the power supply box 3 are both equipped with multiple universal wheels 106, so that the fan 1 and the power supply box 3 can easily move on various ground surfaces.

[0050] In some embodiments, as shown in FIG. 3, the input end and the output end of the fan 1 are both provided with a filter screen 107, which is designed to be detachable and fixed to the inner side of the port of the fan 1 by buckles or bolts. The filter screen 107 is preferably made of stainless steel material with high temperature resistance and corrosion resistance, which can effectively block large particle impurities and sparks in the smoke.

[0051] In some embodiments, as shown in FIG. 10, the power supply box 3 and the fan 1 are both equipped with a double shoulder strap 302, which can adjust the length to adapt to users of different body types, so that users can easily carry the power supply box 3 and the fan 1 to move quickly in the fire scene.

[0052] In some embodiments, a harmful gas detection probe is provided in the fan 1, which further improves the safety and intelligence level of the device. The harmful gas detection probe can monitor the concentration of harmful gases such as carbon monoxide and hydrogen sulfide in the flue gas pumped by the fan 1 in real time. Once the concentration of harmful gases exceeds the safety standard, the probe will immediately issue an alarm to remind the operator to take appropriate measures such as evacuating the scene or adjusting the working state of the device to avoid poisoning or damage to the device. This intelligent design not only improves the automation level of the device, but also effectively prevents potential risks caused by harmful gas leakage.

[0053] Moreover, a 24V battery power supply, an inverter, an explosion-proof protector and a start button are integrated in the power supply box 3. The 24V battery power supply serves as the main power supply to provide power support for the entire device. When the fan 1 needs to be started, the 24V DC output by the battery power supply is first converted into 220V AC through the inverter, then passes through the explosion-proof protector for safety isolation and protection, and finally outputs to the fan 1. The fan 1 is designed to be driven by 220V AC and is equipped with a start button. Firefighters only need to press the start button to start the operation of the fan 1 to start pumping flue gas.

[0054] The specific embodiments are only an explanation of the present application, which is not a limitation of the present application. Those skilled in the art can make modifications to the embodiments without creative contribution after reading the specification, as long as the modifications are within the scope of the claims of the present application.
