Abstract
Description
Technical Field
[0001] This invention relates to firebreak facilities, specifically to a rapidly deployable wildfire firebreak and its usage method. Background Technology
[0002] Forest fires not only cause severe ecological and economic losses, but the large amounts of carbon dioxide they release also seriously hinder current global goals for reducing carbon emissions. Therefore, emergency management measures for forest fires need to be continuously supported by new technologies. Currently, firebreaks mainly rely on two types of measures: one is utilizing natural barriers such as rivers and roads, but their distribution is constrained by terrain, and their fire-stopping effect has obvious regional limitations; the other is constructing firebreaks artificially, i.e., clearing combustible vegetation within a certain width of the ground surface.
[0003] Traditional manual firebreaks require clearing approximately 5 meters of flammable material, typically necessitating 20 firefighters working continuously for 6 to 8 hours per kilometer. In the high temperatures (often exceeding 300°C) and dense smoke of the fire scene, workers face extremely high safety risks. According to statistics from the Forestry Bureau, between 2020 and 2025, approximately 30% of firefighting injuries and fatalities occurred during firebreak construction.
[0004] The existing technology has the following main shortcomings: (1) The natural isolation zone is uncontrollable and its spatial distribution may not coincide with the fire area; (2) The efficiency of manual cleaning is low (about 200 m² / h), which is difficult to keep up with the speed of fire spread; (3) The construction safety risk is prominent, and the probability of personnel suffering heat radiation injury during close-range operations is as high as 62%.
[0005] Therefore, there is an urgent need for a wildfire firebreak that can be quickly deployed, supports modular expansion, and effectively blocks the spread of flames, in order to make up for the shortcomings of traditional fire prevention methods in terms of timeliness, adaptability, and safety. Summary of the Invention
[0006] The present invention aims to provide a firebreak that can be rapidly deployed in mountainous terrain, thereby improving upon the shortcomings of existing firebreak methods in terms of deployment speed, scalability, and construction safety.
[0007] To solve the above-mentioned technical problems, the present invention provides a wildfire isolation strip, comprising: fireproof cloth; uprights and upright rollers, wherein the uprights are slidably inserted through the axis of the upright rollers, and the two are rotatable relative to each other in the circumferential direction and fixed in the radial direction; the inner edge of the fireproof cloth is fixedly connected to the upright rollers, so that the fireproof cloth can unfold with the rotation of the upright rollers; safety hooks and safety hook buckles, wherein a plurality of safety hooks are vertically equidistantly distributed along the outer edge of the fireproof cloth and fixedly connected thereto, and the arrangement height of the plurality of safety hook buckles corresponds one-to-one with the arrangement height of each safety hook, and is fixedly connected to the uprights.
[0008] As a further improvement, a tensioning device is also included, comprising: a top loop, a top tensioning rope, and a top tensioner.

Additionally, a middle loop, a middle tensioning rope, and a middle tensioner are also included. The middle loop is fixedly connected to the middle of the fireproof cloth at equal intervals; the middle tensioning rope passes through the middle loop and is fixed at one end to the upright; the middle tensioner is fixed to the upright and installed at the same height as the middle loop and the middle tensioning rope. The equipment includes a bottom loop, a bottom tension rope, and a bottom tensioner. The bottom loops are fixedly connected to the bottom of the fireproof cloth at equal intervals. The bottom tension rope passes through the bottom loops and is fixed at one end to the upright. The bottom tensioner is fixed to the upright and installed at the same height as the bottom loops and the bottom tension rope.
[0009] As a further improvement, it also includes counterweight tiles, which are fixedly connected to the bottom end of the fireproof cloth.
[0010] As a further improvement, it also includes ground anchor buckles, which are fixedly connected to the bottom end of the fireproof cloth.
[0011] As a further improvement, a wind rope buckle is also included, which is fixedly connected to the top of the column.
[0012] As a further improvement, a ladder is installed on the column roller for firefighters to climb and carry out construction work; the column roller is also equipped with a locking device to prevent the column roller from rotating freely.
[0013] This invention also provides a method for using a wildfire firebreak, comprising the following steps: Based on the location of the forest fire and the distribution characteristics of the surrounding ridges, identifying the ridge where the wildfire firebreak will be installed; using a helicopter to hoist a first post equipped with a safety hook and loop, inserting it into a pre-set anchoring hole at the outermost edge; the helicopter suspending the first wildfire firebreak with ropes and hoisting it to the vicinity of the first post; firefighters using climbing equipment climbing to various positions on the post rollers, connecting the safety hooks and loops on the first post to the safety hooks of the first wildfire firebreak; the helicopter hoisting the first wildfire firebreak, moving it along the ridge towards the first pre-set anchoring hole, so that the fireproof cloth of the first wildfire firebreak is carried by the helicopter. The helicopter moves and gradually unfolds the firebreak; it inserts the posts of the first firebreak into the first pre-set anchor holes; it then hoists the second firebreak to the vicinity of the first firebreak; firefighters use climbing equipment to climb to various positions on the post rollers and connect the safety hooks of the first firebreak to the safety hooks of the second firebreak one by one; the helicopter hoists the second firebreak and moves it along the ridge toward the second pre-set anchor holes, causing the fireproof cloth of the second firebreak to gradually unfold as the helicopter moves; the helicopter inserts the posts of the second firebreak into the second pre-set anchor holes; the above hoisting and connection steps are repeated to complete the installation of subsequent sections of the firebreak.
[0014] This invention also provides another method for using firebreaks, comprising the following steps: Based on the location of the forest fire and the distribution characteristics of the surrounding ridges, identifying the ridge where the firebreak will be installed; using a helicopter to hoist a first post equipped with a top tensioner, a middle tensioner, a bottom tensioner, and a safety hook and loop, inserting it into a pre-set anchoring hole at the outermost edge; the helicopter suspends the first firebreak via ropes and hoists it to the vicinity of the first post; firefighters use climbing equipment to ascend to various positions on the post rollers and align the safety hook and loop on the first post with the safety hook of the first firebreak. The top, middle, and bottom tension ropes of the first firebreak should be connected and installed in the top tensioner, middle tensioner, and bottom tensioner of the first post, respectively. A helicopter will hoist the first firebreak and move it along the ridge towards the first pre-set anchor hole, causing the fireproof cloth of the first firebreak to gradually unfold as the helicopter moves. The helicopter will insert the posts of the first firebreak into the first pre-set anchor holes.

The top and bottom tension ropes are fully tightened; the guy rope buckles and ground stake buckles of the first firebreak are secured; the helicopter lifts the second firebreak to the vicinity of the first firebreak; firefighters use climbing equipment to climb to various positions on the column rollers, connecting the safety hook buckles of the first firebreak to the safety hooks of the second firebreak one by one, and installing the top, middle, and bottom tension ropes of the second firebreak into the top, middle, and bottom tensioners of the first firebreak, respectively; the helicopter lifts the second firebreak along... The ridge moves towards the second pre-set anchor hole, causing the fireproof cloth of the second firebreak to gradually unfold as the helicopter moves; the helicopter inserts the posts of the second firebreak into the second pre-set anchor hole; firefighters tighten the top, middle, and bottom tensioners on the first firebreak, and tighten all the top, middle, and bottom tensioners on the second firebreak; the guy rope buckles and ground stake buckles of the second firebreak are secured; the above hoisting, connecting, tightening, and securing steps are repeated to complete the installation of subsequent sections of the firebreak.
[0015] Compared with the prior art, the present invention has the following beneficial technical effects: Making full use of terrain advantages: Considering the characteristics of mountainous terrain, this system utilizes a naturally formed three-tiered ridge system (primary main ridge, secondary secondary ridge, and tertiary branch ridge) to construct a firebreak network. By prioritizing the deployment of firebreaks along the primary / secondary ridges, and relying on the natural continuity of the ridgeline, the forest area is divided into multiple closed units, thus forming strip-shaped firebreaks on higher ridges, achieving full-area physical separation of the fire zone. Fire isolation mechanism: The fire isolation belt of this invention uses fireproof cloth with a vertical height of ≥10m and high flame retardancy as the core isolation barrier. The fireproof cloth with aluminum foil layer has the dual functions of high temperature barrier and heat radiation barrier, which can effectively cut off the flame propagation path and prevent the fire from spreading laterally; Low-combustible geological base: As a tectonic uplift zone, the mountain ridge has been subjected to long-term differential weathering, resulting in exposed bedrock. This characteristic eliminates pathways for underground fire spread and prevents flames from penetrating through fissures at the bottom of the firebreak. Rapid Deployment by Air: Through helicopter hoisting and coordinated operations, the firebreak of this invention can be rapidly deployed in a modular manner to meet the emergency response needs during wildfire outbreaks.

It should be noted that the column 3 and the column roller 301 can move relative to each other in the circumferential direction, but there is no relative movement in the radial direction.
[0034] The inner edge of the fireproof cloth 1 is fixedly connected to the column roller 301. The reason for this arrangement is that when the wildfire isolation belt of the present invention is in use, the fireproof cloth 1 can be quickly unfolded as the column roller 301 rotates while the column 3 remains fixed.
[0035] The wind rope buckle 302 is fixedly connected to the top of the column 3.
[0036] refer to Figure 3 The counterweight tiles 201 and ground nail buckles 202 are fixedly connected to the bottom end of the fireproof cloth 1. Safety hooks 401 are evenly distributed along the outer edge of the fireproof cloth 1 and fixedly connected thereto. The safety hook buckles 402 correspond one-to-one with the safety hooks 401 in height and are fixedly connected to the column 3. It should be noted that the safety hooks 401 and safety hook buckles 402 are installed in pairs, and each pair of safety hooks and safety hook buckles is installed at the same height.
[0037] refer to Figure 3 and Figure 4 The top loops 701 are fixedly connected to the top of the fireproof cloth 1 at equal intervals. The top tension rope 801 passes through the top loops 701, and one end is fixedly connected to the upright 3. The top tensioner 901 is fixedly connected to the upright 3.

It should be noted that the central loops 702, the central tension rope 802, and the central tensioner 902 are installed at the same height.
[0039] Bottom loops 703 are fixedly connected to the bottom of the fireproof cloth 1 at equal intervals. Bottom tension ropes 803 pass through the bottom loops 703, and one end is fixedly connected to the upright 3. Bottom tensioner 903 is fixedly connected to the upright 3. It should be noted that the bottom loops 703, bottom tension ropes 803, and bottom tensioner 903 are installed at the same height.
[0040] refer to Figures 1 to 4 This can also be used to illustrate a second embodiment of the wildfire isolation belt of the present invention. The wildfire isolation belt includes a fireproof cloth 1, uprights 3, upright rollers 301, safety hooks 401, and safety hook buckles 402.
[0041] refer to Figure 1 and Figure 2 The column 3 is located at the axis of the column roller 301; the column 3 is slidably connected to the column roller 301. It should be noted that the column 3 and the column roller 301 can move relative to each other in the circumferential direction, but there is no relative movement in the radial direction.
[0042] The inner edge of the fireproof cloth 1 is fixedly connected to the column roller 301. The reason for this arrangement is that when the wildfire isolation belt of the present invention is in use, the fireproof cloth 1 can be quickly unfolded as the column roller 301 rotates while the column 3 remains fixed.
[0043] refer to Figure 3 Safety hooks 401 are evenly distributed along the outer edge of the fireproof cloth 1 and fixedly connected thereto. Safety hook rings 402 are arranged at heights corresponding to the safety hooks 401 and are fixedly connected to the uprights 3. It should be noted that the safety hooks 401 and safety hook rings 402 are installed in pairs, with each pair of safety hooks and safety hook rings installed at the same height.
[0044] In some embodiments, a ladder is installed on the upright roller 301 of the wildfire isolation zone of the present invention for firefighters to climb and carry out construction work. A locking device is provided on the upright roller 301 to prevent free rotation of the upright roller 301.
[0045] refer to Figures 5 to 7 The method of using the wildfire firebreak according to the first embodiment of the present invention is as follows: Step 1: Reference Figure 5 and Figure 6Based on the location of the forest fire and the distribution characteristics of the surrounding ridges, the locations of the ridges for installing firebreaks were determined. This selection was made because ridges are structurally high and sparsely vegetated, and their strip-like distribution divides the forest into several independent units. Therefore, installing firebreaks on ridges is most effective in isolating fire sources.
[0046] Step 2: Use a helicopter to hoist a first column equipped with a top tensioner 901, a middle tensioner 902, a bottom tensioner 903, and a safety hook 402, and insert it into the preset anchoring hole at the outermost edge position.
[0047] Step 3: The helicopter suspends the first firebreak using ropes and hoists it to the vicinity of the first pillar 3 from Step 2.
[0048] Step 4: Firefighters use climbing equipment to climb to the corresponding positions on the column roller 301, connect the safety hooks 402 on the first column to the safety hooks 401 on the first firebreak, and install the top tension rope 801, middle tension rope 802, and bottom tension rope 803 of the first firebreak into the top tensioner 901, middle tensioner 902, and bottom tensioner 903 of the first column, respectively.
[0049] Step 5: The helicopter hoists the first firebreak and moves it along the ridge toward the first pre-set anchor hole. Since the outer edge of the fireproof cloth 1 of the first firebreak is fixedly connected to the first post, the fireproof cloth 1 of the first firebreak will gradually unfold as the post 3 moves with the helicopter.
[0050] Step Six: The helicopter inserts the first firebreak post 3 into the first pre-set anchor hole.
[0051] Step 7: Firefighters tighten the ropes using the top tensioner 901, middle tensioner 902, and bottom tensioner 903 on the first upright. This operation tightens all the top tensioning ropes 801, middle tensioning ropes 802, and bottom tensioning ropes 803 on the first firebreak, ensuring that the fireproof cloth 1 of the first firebreak will not deform significantly due to strong winds or other factors.
[0052] Step 8: Secure the guy rope buckles 302 and ground stake buckles 202 of the first wildfire isolation zone using existing technology.
[0053] Step Nine: The helicopter will airlift the second firebreak to the vicinity of the first firebreak.
[0054] Step 10: Firefighters use climbing equipment to climb to the corresponding positions on the column roller 301, connect the safety hooks 402 of the first firebreak to the safety hooks 401 of the second firebreak one by one, and install the top tension rope 801, middle tension rope 802 and bottom tension rope 803 of the second firebreak into the top tensioner 901, middle tensioner 902 and bottom tensioner 903 of the first firebreak, respectively.
[0055] Step 11: The helicopter hoists the second firebreak and moves it along the ridge toward the second pre-set anchoring hole. Since the outer edge of the fireproof cloth 1 of the second firebreak is already fixedly connected to the first firebreak, the fireproof cloth 1 of the second firebreak will gradually unfold as the support column 3 moves with the helicopter.
[0056] Step 12: The helicopter inserts the post 3 of the second firebreak into the second pre-set anchor hole.
[0057] Step Thirteen: Firefighters tighten the top tension rope 901, middle tension rope 902, and bottom tension rope 903 on the first firebreak. This operation tightens all the top tension rope 801, middle tension rope 802, and bottom tension rope 803 on the second firebreak, ensuring that the fireproof cloth 1 of the second firebreak will not deform significantly due to strong winds or other factors.
[0058] Step Fourteen: Secure the wind rope buckles 302 and ground stake buckles 202 of the second wildfire isolation zone using existing technology.
[0059] Step 15: Repeat steps 9 to 14 above to connect the third firebreak with the second firebreak, the fourth firebreak with the third firebreak, the fifth firebreak with the fourth firebreak, the sixth firebreak with the fifth firebreak, and so on, until all firebreaks are installed.
[0060] refer to Figures 5 to 7 The method of using the wildfire firebreak according to the second embodiment of the present invention is as follows: Step 1: Reference Figure 5 and Figure 6 Based on the location of the forest fire and the distribution characteristics of the surrounding ridges, the locations of the ridges for installing firebreaks were determined. This selection was made because ridges are structurally high and sparsely vegetated, and their strip-like distribution divides the forest into several independent units. Therefore, installing firebreaks on ridges is most effective in isolating fire sources.
[0061] Step 2: Use a helicopter to lift the first column equipped with a safety hook 402 and insert it into the preset anchor hole at the outermost edge position.
[0062] Step 3: The helicopter suspends the first firebreak using ropes and hoists it to the vicinity of the first pillar 3 from Step 2.
[0063] Step 4: Firefighters use climbing equipment to climb to the corresponding positions of the column rollers 301 and connect the safety hooks 402 on the first column to the safety hooks 401 of the first wildfire isolation zone one by one.
[0064] Step 5: The helicopter hoists the first firebreak and moves it along the ridge toward the first pre-set anchor hole. Since the outer edge of the fireproof cloth 1 of the first firebreak is fixedly connected to the first post, the fireproof cloth 1 of the first firebreak will gradually unfold as the post 3 moves with the helicopter.
[0065] Step Six: The helicopter inserts the first firebreak post 3 into the first pre-set anchor hole.
[0066] Step 7: The helicopter will transport the second firebreak to the vicinity of the first firebreak.
[0067] Step 8: Firefighters use climbing equipment to climb to the corresponding positions on the column roller 301 and connect the safety hooks 402 of the first firebreak to the safety hooks 401 of the second firebreak one by one.
[0068] Step Nine: The helicopter hoists the second firebreak and moves it along the ridge toward the second pre-set anchoring hole. Since the outer edge of the fireproof cloth 1 of the second firebreak is already fixedly connected to the first firebreak, the fireproof cloth 1 of the second firebreak will gradually unfold as the support column 3 moves with the helicopter.
[0069] Step 10: The helicopter inserts the post 3 of the second firebreak into the second pre-set anchor hole.
[0070] Step 11: Secure the guy rope buckles 302 and ground stake buckles 202 of the second wildfire isolation zone using existing technology.
[0071] Step 12: Repeat steps 7 to 11 above to connect the third firebreak with the second firebreak, the fourth firebreak with the third firebreak, the fifth firebreak with the fourth firebreak, the sixth firebreak with the fifth firebreak, and so on, until all firebreaks are installed.
[0072] refer to Figure 4It should be noted that connector 5 is a type of connector used by helicopters to lift and transport the firebreaks of this invention. This connector can be remotely controlled to grasp and release the firebreaks of this invention. The technology and usage of connector 5 can be found in existing technologies, and will not be elaborated upon here.
[0073] In some embodiments, the first step of the method described in the first embodiment further includes: using a helicopter-mounted chainsaw to trim the branches and leaves of trees on both sides of the pre-defined wildfire isolation zone. Specific implementation methods can refer to existing technologies that use helicopter-mounted chainsaws to trim branches and leaves of trees near high-voltage power lines. The purpose of this arrangement is to minimize the proximity of ignition sources to the wildfire isolation zone of this invention.
[0074] In some embodiments, after the firebreak is constructed, unmanned helicopters and robotic dogs equipped with fire extinguishers are used around its perimeter to conduct real-time patrols and extinguish any sporadic fires that may penetrate the firebreak.
[0075] In some embodiments, using a helicopter to transport drilling equipment to a predetermined location to open pre-set anchor holes has the advantage of enabling rapid response to fire-fighting missions.
[0076] In other embodiments, a fleet of vehicles is used to transport drilling equipment to a predetermined location for the opening of pre-set anchoring holes, which has the advantage of lower construction costs.
[0077] In some embodiments, the top end of the guy rope is connected to the top of the post 3 of the firebreak of the present invention, and the bottom end of the guy rope is connected to the ground anchor. The purpose of this arrangement is to ensure that the firebreak of the present invention can maintain its shape and stability in windy weather.
[0078] In some embodiments, multiple unmanned heavy-duty helicopters are used in parallel to complete the deployment of all firebreaks more quickly.
