This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Figure 1 This is a schematic diagram of a fire extinguishing device according to an embodiment of this application.

[0028] refer to Figure 1The fire extinguishing device 1000 includes a fire extinguishing cart 1100 and a fireproof barrier 1200. The fire extinguishing cart 1100 includes a fire extinguishing nozzle 1110 and a fire extinguishing material tank 1120 connected to the fire extinguishing nozzle 1110. The fire extinguishing nozzle 1110 of the fire extinguishing cart 1100 can spray the individual fire extinguishing materials stored in the fire extinguishing material tank 1120 to the fire point. The fireproof barrier 1200 can enclose the burning target, thereby isolating flames and high temperatures, and can facilitate the accumulation of fire extinguishing materials to cover the burning template, achieving efficient fire extinguishing. The fireproof barrier 1200 can be used in conjunction with the fire extinguishing cart 1100 or independently. This application specification and accompanying drawings illustrate the structure of the fireproof barrier 1200 using the fireproof barrier 1200 in conjunction with the fire extinguishing cart 1100 as an example.

[0029] Figure 2 This is a partial enlarged view of a fireproof enclosure according to an embodiment of this application.

[0030] refer to Figure 2 The fireproof enclosure 2000 provided in this application has a telescopic structure, which allows it to be used with various fire extinguishing and firefighting equipment for portable transportation and rapid deployment. The fireproof enclosure 2000 includes a telescopic pole fixing frame 2100, a telescopic pole 2200, and a first scissor link assembly 2300. The fireproof enclosure 2000 according to the embodiment of this application has the same structure as the fireproof enclosure 1000, and will not be described differently below.

[0031] The telescopic pole mounting bracket 2100 can be a rigid support made of stainless steel or similar materials, serving as the base for the telescopic movement of the fireproof barrier 2000. The telescopic pole 2200 can be driven by various power sources, such as an electric motor or a compressed gas source. The telescopic pole 2200 includes a fixed end and a movable end that can extend and retract relative to the fixed end. The fixed end of the telescopic pole 2200 is fixedly connected to the telescopic pole mounting bracket 2100, thereby providing support for the extension and retraction of the telescopic pole 2200.

[0032] The first scissor lift linkage 2300 can be composed of multiple connecting links, with adjacent links (e.g., links 2310 and 2320) hinged to each other. The rightmost end of the first scissor lift linkage 2300 is the fixed end, which is connected to the movable end of the telescopic rod 2200. Therefore, when the telescopic rod 2200 extends, the first scissor lift linkage 2300 is pushed out; conversely, when the telescopic rod 2200 retracts, the first scissor lift linkage 2300 is pulled back. A first fireproof cloth 2400 covers the outside of the scissor lift linkage 2300. The first fireproof cloth 2400 may have a foldable structure. For example, a rope can be connected between the movable end and the fixed end of the first scissor lift linkage 2300. The first fireproof cloth 2400 is hung on the rope. Therefore, when the first scissor link assembly 2300 is deployed, the first fireproof cloth 2400 also deploys along with the deployment of the first scissor link assembly 2300; when the first scissor link assembly 2300 is retracted, the first fireproof cloth 2400 also folds along with the retraction of the first scissor link assembly 2300.

[0033] In scenarios involving firefighting of a burning vehicle, the first fireproof cloth 2400 is used to cover the areas on both sides of the vehicle (i.e., the door area). As the fire truck (e.g., fire extinguisher 1100) carrying the fireproof barrier moves towards the burning vehicle, the first scissor lift assembly 2300 and the first fireproof cloth 2400 are in a retracted / folded state, facilitating the movement of the fire truck and improving its maneuverability. Upon arrival near the burning vehicle, the first scissor lift assembly 2300 and the first fireproof cloth 2400 can be deployed. To further reduce the size of the fireproof barrier when folded, the telescopic pole mounting bracket 2100 can be fixed to the sliding rod.

[0034] Figure 3 This is a magnified view of a portion of the area near the telescopic pole mounting bracket.

[0035] refer to Figure 3 The fireproof enclosure 2000 also includes a base 2500. The base 2500 can be connected to a fire truck (e.g., a fire extinguisher 1100). The fireproof enclosure 2000 also includes a sliding bar. Figure 3 The slide bar is shown in the form of a first slide bar 2610 and a second slide bar 2620. However, those skilled in the art will understand that the slide bar may include only one slide bar or more than two slide bars, as long as the function of unfolding along the width direction of the train can be realized.

[0036] According to an embodiment of this application, the first slide bar 2610 and the second slide bar 2620 can be driven by a power source (e.g., an electric motor) and symmetrically extend to both sides.

[0037] According to another embodiment of this application, the first slide bar 2610 and the second slide bar 2620 can be driven independently by different power sources, thereby achieving independent precession control. This may be advantageous in actual firefighting scenarios. In situations such as underground parking garages or places with high density of people and vehicles, the fire truck (e.g., fire extinguishing cart 1100) may not be able to be precisely aligned with the burning vehicle due to limitations of the surrounding environment. In this case, if the total length of the first slide bar 2610 and the second slide bar 2620 is greater than the width of the burning vehicle, the fire truck (e.g., fire extinguishing cart 1100) can asymmetrically deploy the first slide bar 2610 and the second slide bar 2620 according to the relative position between the fire truck and the burning vehicle, so that both sides of the burning vehicle can be covered by the first fireproof cloth.

[0038] Since the first scissor lift linkage 2300 and the first fireproof cloth 2400 are used to shield both sides of the burning vehicle along its length, the total extension length of the first scissor lift linkage 2300 is relatively long. To enhance the rigidity of the first scissor lift linkage 2300, the first scissor lift linkage 2300 according to the embodiment of this application adopts a double-layer linkage structure, with the two layers of linkages connected by a pin.

[0039] To further reduce the size of the fireproof enclosure 2000 after it is stowed away, the fireproof enclosure 2000 also includes a rotatable structure. (Reference) Figure 4 The fireproof enclosure 2000 includes a slewing support frame 3100. The telescopic pole fixing frame 2100 is rotatably connected to the slewing support frame 3100 via a slewing support shaft 3200. When the fireproof enclosure 2000 is stored, the telescopic pole fixing frame 2100 rotates 180 degrees clockwise from its previous state, thus folding to the right side of the slewing support frame 3100.

[0040] Although only one telescopic rod fixing bracket 2100 is shown in the figure, as Figures 1 to 3 As shown, the fireproof enclosure 2000 also includes another telescopic pole fixing frame symmetrical to the telescopic pole fixing frame 2100.

[0041] Figure 5 This is a magnified view of a portion of the area near the movable end of the first scissor lift linkage of the fireproof enclosure.

[0042] refer to Figure 5At the movable end of the first scissor lift assembly 2300, a module for deploying fireproof cloth at the front or rear of a burning vehicle is fixed. Specifically, a first lead screw 4100 is fixed at the movable end of the first scissor lift assembly 2300. A first slider 4200 is threaded onto the first lead screw 4100. The first lead screw 4100 can be rotated by a motor, thereby causing the first slider 4200 to move up and down. A second scissor lift assembly 4300 is connected to the first slider 4200. Under the up and down pushing of the first slider 4200, the second scissor lift assembly 4300 can extend and retract. Similar to the first protective cloth, a foldable second fireproof cloth (not shown in the figure) is provided on the second scissor lift assembly 4300. Since the second scissor link assembly 4300 and the second fireproof cloth are used to cover the front or rear of the vehicle, and the width of the vehicle is usually relatively small, in order to reduce the overall weight of the fireproof barrier 2000, the second scissor link assembly 4300 can be set as a single-layer link assembly.

[0043] A wheel assembly 4400 is provided below the first lead screw 4100, which can drive the first lead screw 4100 and the scissor linkage assembly 4300 to move when the first scissor linkage assembly 2300 extends or retracts. The wheel assembly 4400 includes a fixed wheel 4410 and a foldable wheel 4420. The foldable wheel 4420 can be folded elastically according to the undulation of the road surface, thereby improving the passability of the fireproof barrier 2000 when extended.

[0044] The first lead screw 4100, the second scissor link assembly 4300, and the second fireproof cloth can also be installed in pairs, so that they can extend from both sides to the middle. This can further reduce the strength requirement of the second scissor link assembly 4300 and improve the structural strength of the fireproof enclosure 2000.

[0045] Figure 6 This is a partial enlarged view of the fireproof barrier on one side of the telescopic pole fixing frame.

[0046] refer to Figure 6On this side of the telescopic pole fixing frame 2100, a second lead screw 5100 may also be provided. The second lead screw 5100 is fixedly connected to the telescopic pole fixing frame 2100. A second slider 5200 is threadedly connected to the second lead screw 5100. The second lead screw 5100 can be driven by a motor to rotate, thereby driving the second slider 5200 to move up and down. A third scissor linkage assembly 5300 is connected to the second slider 5200. Under the up and down pushing of the second slider 5200, the third scissor linkage assembly 5300 can extend and retract. Similar to the first protective cloth, a foldable second fireproof cloth (not shown in the figure) is provided on the third scissor linkage assembly 5300. Since the third scissor linkage assembly 5300 and the second fireproof cloth are used to cover the front or rear of the vehicle, and the width of the vehicle is usually relatively small, in order to reduce the overall weight of the fireproof barrier 2000, the third scissor linkage assembly 5300 can be set as a single-layer linkage assembly. A foldable third fireproof cloth (not shown) is provided on the third scissor link assembly 5300.

[0047] The second lead screw 5100, the third scissor linkage group 5300, and the third fireproof cloth can also be installed in pairs, so that they can extend from both sides to the middle. This can further reduce the strength requirement of the third scissor linkage group 5300 and improve the structural strength of the fireproof enclosure 2000.

[0048] The fireproof barrier 2000 according to the embodiments of this application may also be equipped with a sensor module to sense the position and size of the burning vehicle. Alternatively, fire trucks that cooperate with the fireproof barrier 2000 provided in the embodiments of this application may be equipped with such sensor modules. The fireproof barrier 2000 according to the embodiments of this application can automatically determine the required extension length of each scissor lift assembly based on the position and size of the burning vehicle detected by the sensor module, thereby realizing the automatic deployment of the fireproof barrier.

[0049] The above description is merely an illustration of the embodiments of this application and the technical principles employed. Those skilled in the art should understand that the scope of protection involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the described technical concept.
