    DESCRIPTION
    Firewall suspension apparatus and procedure to use it to stop the spread of fire.
    Background of the invention
    Field of the Invention
    The present invention relates to a firewall suspension apparatus and a method of using said apparatus to stop the spread of fire. More particularly, the present invention relates to a firebreak suspension apparatus for stopping the spread of a forest fire and a method for using said apparatus.
    Description of the prior art
    Worldwide, wildfires or large-scale uncontrolled fires occur more frequently as climate change worsens, and sometimes they are complicated due to other natural or human factors. Forest fires predominate particularly in autumn and winter. Over the past 20 years, large uncontrolled fires, such as the uncontrolled fire of 1987 at Daxing'anling in China, the uncontrolled fires of 2010 in Russia and the uncontrolled fires of 2010 in California, have caused enormous damage to property, human lives and the natural environment because the flames lasted a long time and affected a large area each time. Since forest fires tend to occur in windy mountainous areas difficult to reach for firefighters, stopping forest fires has always been a great challenge. Although firefighters have managed to reach the site, it is difficult to quell the flames on trees 10 meters high with existing fire extinguishing equipment.
    It is not uncommon to see news about forest fires or wild lands. Since normally a forest covers a large area and that each piece of land within the forest can become a trigger to induce another fire, if forest fires cannot be suffocated in an early state, they can lead to disastrous results. The uncontrolled fire of 2016 at Fort McMurray in Canada is

    A recent example. The uncontrolled fire began approximately 15 km southwest of the city of Fort McMurray in Alberta, Canada, on May 1, 2016. It spread rapidly and swept the city, destroying more than 2,400 homes and buildings and causing the greatest evacuation by fire uncontrolled of the history of Alberta. The uncontrolled fire continued to spread to northern Alberta and reached Saskatchewan on May 19, spreading through almost 590,000 hectares (1,500,000 acres) before it was declared under control on July 5, 2016. Uncontrolled fire hindered Canadian oil sand operations and it was the most expensive natural disaster in the history of Canada. It is clear that forest fires can have disastrous results.
    Various firefighting equipment has been developed to solve problems related to forest fires. Most existing fire extinguishing technologies focus on ground fire extinguishing equipment or air fire extinguishing techniques that use helicopters to spray water or fire extinguishing foam. However, sprayed water or foam can easily evaporate or be removed by wind, obtaining little success in extinguishing forest fires.
    Summary of the invention
    An object of the present invention is to provide a firebreak suspension apparatus that can prevent a forest fire from spreading further, and a method of using said apparatus to prevent the spread of fire.
    Another object of the present invention is to provide a firebreak suspension apparatus that can effectively block the propagation of a forest fire, and a method of using said apparatus to stop the spread of fire.
    To achieve the above objectives, a firewall suspension apparatus according to the present invention comprises an upper suspension device and a lower suspension device.

    Detailed description of the preferred embodiments
    Figure 1 shows a firewall suspension apparatus (100) comprising an upper suspension device (10) and a lower suspension device (20). The upper suspension device (10) includes a first transmission mechanism (11), a plurality of trees (12) having fire retardant fabrics (14) therein, and an upper suspension support frame (13), in that the shafts (12) and the first transmission mechanism (11) are mounted on the upper suspension support frame (13), and the first transmission mechanism (11) drives the shafts (12) to unwind or wind up the fireproof fabrics (14). The lower suspension device (20) includes a second transmission mechanism (21), a plurality of first cutter shafts (22), and a first lower suspension support frame (23). The first cutter shafts (22) and the second transmission mechanism (21) are mounted on the first lower suspension support frame (23), which is suspended at the lower end of the fire retardant fabrics (14). The second transmission mechanism (21) drives the first cutter shafts (22), so that the objects under the lower suspension device (20) can be easily cut and felled by the first cutter shafts (22).
    Figure 1 shows that the firewall suspension apparatus (100) according to the present invention further comprises suspension arms (30) in the upper suspension support frame (13). The suspension arms (30) are used to suspend the firewall suspension apparatus (100) of a helicopter (not shown), so that the firewall suspension apparatus (100) can be suspended from a helicopter used in a task of Fire extinguishing that aims to create a separation between parts in flames and without flames at the place of fire and to extinguish the fire further. In an embodiment of the present invention, each of the flame retardant fabrics (14) has a width of 50 m and a length of 200 m. The flame retardant fabrics (14) arranged in each tree (12) are separated from each other; In addition, as shown in Figure 1, the flame retardant fabrics (14) in each two adjacent trees are arranged alternately to reduce wind speed. In addition, each

    Fire retardant fabric (14) has at least two holes (not shown) on opposite sides thereof, and a steel cable (15) passes through each hole to connect the upper suspension device (10) and the suspension device lower (20) to support the weight of the lower suspension device (20).
    Figure 2 is a schematic view of the lower suspension device of the firewall suspension apparatus. The lower suspension device (20) of the firewall suspension apparatus (100) further comprises a plurality of third transmission mechanisms (24) and a plurality of second cutter shafts (25). A pair of cutters (26) are provided on two opposite sides of each second cutter shaft (25). The third transmission mechanisms (24), the second cutter shafts (25) and the cutters (26) are arranged on the outer edge of the first lower suspension support frame (23). The third transmission mechanisms (24) drive the second cutter shafts (25), which then cause the cutters (26) to move, so that the cutters (26) can easily stop and cut down objects around the lower suspension device (20).
    See Figure 2 and Figure 3. Figure 3 is a schematic view showing a single cutter shaft and a pair of cutters according to the present invention. In this embodiment, each cutter (26) comprises a guide plate (27) and a chain (28). The guide plate (27) is fixed to the outer edge of the first lower suspension support frame (23) by means of a support part (29). The second cutter shaft (25) is a cogwheel, whose teeth fit into the chains (28) and are coupled therewith. As such, when each third transmission mechanism (24) drives a corresponding second cutter shaft (25), that second cutter shaft (25) then causes, therefore, the chains (28) on two opposite sides to wind up. Consequently, the cutters (26) are also simultaneously winding to cut and cut nearby objects.
    Furthermore, in this embodiment, the first lower suspension support frame (23) is in the form of a cuboid. Each of the two long opposite sides of the first lower suspension support frame (23) is provided with three sets of a third transmission mechanism (24), a second cutter shaft (25), and a pair of cutters (26 ). On the contrary, each of the two opposite short sides is provided with a set of a third transmission mechanism (24), a second cutter shaft (25), and a pair of cutters (26). Every two seconds cutter trees

    Adjacent (25) are arranged in such a way that they do not align, and therefore, each pair of cutters (26) connected to a second cutter shaft (25) does not align with another pair of cutters (26). In addition, in this embodiment, each pair of cutters (26) connected to a second cutter shaft (25) overlaps with another pair of cutters (26). Thus, when a pair of cutters (26) is rolling up and cutting down objects, the objects are not likely to get stuck between two adjacent pairs of cutters (26). In addition, the only pair of cutters (26) on each of the two short opposite sides has a length that is greater than the width of the first lower suspension support frame (23), and extends beyond the cutters in the opposite sides long. Similarly, this arrangement can prevent objects from getting stuck between two adjacent pairs of cutters while they are curling up and cutting down objects. As such, for the firewall suspension apparatus (100), the specific arrangement of the third transmission mechanisms (24), the second cutter shafts (25) and the cutters (26) allows the lower suspension device (20 ) work in a larger area to cut and cut objects around it; furthermore, objects can be cut and felled more completely by means of the lower suspension device (20).
    See Figure 4 and also Figures 1 and 2 as necessary. Figure 4 is a schematic view showing the use of the firebreak suspension apparatus according to the present invention. When a forest fire occurs and multiple helicopters are ready to be sent to the place of the fire, the firewall suspension devices (100) of the present invention can be suspended from the helicopters and sent together to the place of the fire. The number of firewall suspension devices (100) to be used at the fire site is based on the magnitude of the fire. When helicopters with firebreak suspension devices (100) reach the site of the fire, they can be used to surround burning areas depending on the spread and severity of the forest fire. Then, the first transmission mechanism (11) of each firewall suspension apparatus (100) can drive the plurality of trees (12) having fire retardant fabrics (14) therein. The flame retardant fabrics (14) in each firewall suspension apparatus (100) can be slowly unwound and, at the same time, the second transmission mechanism (21) can drive the plurality of first cutter shafts (22) to cut and cut branches or tree trunks under the lower suspension device (20). Meanwhile, the plurality of third transmission mechanisms (24) can drive the respective second cutter shafts (25) to

    35
    cut and cut down tree branches or trunks around the lower suspension device (20). The flame retardant fabrics (14) can stop the spread of the flames forming a surface of firewalls, which creates a separation between parts in flames and without flames in the place of the fire. In addition, each firewall suspension apparatus (100) is arranged so that its axial direction and wind direction form an acute angle. As such, when the wind blows in the direction of the firewall suspension devices (100) that have been set to surround the flames, the wind has to blow through several rows of flame retardant fabrics (14) arranged alternately in each apparatus (100) of suspension of firewalls and then will become increasingly weak. In Figure 4, the wind directions are indicated by the arrows. It can be seen that the wind blowing through the first firewall suspension apparatus (100) is indicated by thick bold arrows. When the wind comes into contact with the first row of fire retardant fabrics (14) in the first firewall suspension apparatus (100), the wind is hindered a bit and then continues to blow towards the next row of flame retardant fabrics (14) . Therefore, after flowing through the rows of fire retardant fabrics in the plurality of firewall suspension apparatuses (100), the wind that reaches the fire retardant fabrics in the last helicopter suspended suspension apparatus (100) is suspended from the helicopter. has weakened considerably, as indicated by the thin dashed arrows. As such, the wind can be effectively blocked and the spread of the flames can be stopped. The helicopters can then release water from suspended spray systems to help extinguish the fire. As such, the firewall suspension apparatus (100) of the present invention can effectively prevent the fire from spreading further.
    Figure 5 is a flowchart showing a procedure for using the firebreak suspension apparatus of the present invention to stop the spread of fire. The procedure comprises the following steps. First, in step (S1), determine the wind direction of the fire place. Then, in step (S2), based on the magnitude of the fire, use multiple helicopters to suspend the firebreak suspension devices respectively, by means of which the firebreak suspension devices are disposed to windward; the axial direction of each firewall suspension apparatus and the wind direction form an acute angle; and a plurality of firewall suspension devices are suspended and arranged along the wind path. Then, in step (S3), make the upper suspension device of each firewall suspension apparatus
    Unroll the flame retardant fabrics and have the lower suspension device of each cutter suspension apparatus cut and crease objects from below. Finally, in step (S4), make the fire retardant fabrics in the firebreak suspension devices form a surface of firewalls, which creates a separation between parts in flames 5 and without flames in the fire place.
    A firebreak suspension apparatus according to the present invention is intended to be suspended from a helicopter to reach the site of the fire, and is disposed to windward depending on the direction of the wind at the site of the fire. The lower suspension device 10 of the firewall suspension apparatus can be used to cut and cut obstacles around or under it. In addition, the flame retardant fabrics in the upper suspension device can be used to form a firewall surface, which creates a separation between parts in flames and without flames at the site of the fire. As such, the firewall suspension apparatus according to the present invention can effectively stop the spread of a forest fire.
