[0026] In some embodiments, a first zipper is provided at the top of the annular support frame, and a second zipper is provided at the bottom of the fourth fireproof cloth;

[0036] The beneficial effects of this utility model embodiment are as follows:

[0037] The forest and grassland fire prevention and flame retardant device provided in this embodiment includes a barrel-shaped telescopic firewall. The barrel-shaped telescopic firewall includes annular support frames, a first flexible connecting component, a first ground fixing component, a first fireproof cloth, a second fireproof cloth, and a third fireproof cloth. Multiple annular support frames are arranged sequentially. The first flexible connecting component connects every two adjacent annular support frames, making the interval between every two adjacent annular support frames adjustable. The first ground fixing component is disposed on at least one annular support frame to fix the barrel-shaped telescopic firewall to the ground. The first and second fireproof cloths are disposed on both sides of the multiple annular support frames for laying on the ground on the fire-facing and fire-resistant sides of the barrel-shaped telescopic firewall. The third fireproof cloth is disposed on the fire-resistant side of the multiple annular support frames facing the barrel-shaped telescopic firewall.

[0038] When forest and grassland fire prevention and flame retardant devices are applied to forest and grassland fire prevention, on the one hand, multiple ring-shaped support frames are sequentially spaced apart, and the first ground fixing component is fixed to the ground, so that the barrel-shaped telescopic firewall is extended and in a fire-retardant state. Because the multiple ring-shaped support frames are sequentially spaced apart, multiple independent, liftable support positions can be formed with the ground. Furthermore, due to the small contact area between the bottom of the ring-shaped support frames and the ground, the forest and grassland fire prevention and flame retardant device easily adapts to uneven terrain environments such as grasslands, dunes, deserts, shrublands, and woodlands, forming good support with the ground. On the other hand, with the barrel-shaped telescopic firewall extended and in a fire-retardant state, the first and second fireproof cloths are laid on the ground on both sides of the ring-shaped support frames, which can smother and extinguish ground flames. The third fireproof cloth is unfolded on the fire-facing side of the multiple ring-shaped support frames facing the barrel-shaped telescopic firewall, which can block ground flames. Using both smothering and blocking methods for fire prevention and flame retardancy can achieve efficient fire prevention and flame retardancy.

[0039] When the forest and grassland fire prevention and flame retardant device is in standby mode, multiple ring-shaped support frames are arranged in close succession, so that the barrel-shaped telescopic firewall is retracted and in a retracted state. Because the barrel-shaped telescopic firewall is lightweight, small in size, and foldable, it can be carried by a single soldier and quickly erected, moved, and retrieved, thus effectively improving the fire prevention and flame retardant effect of the forest and grassland fire prevention and flame retardant device.

[0061] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art based on this application are within the protection scope of the present utility model.

[0062] Forests and grasslands are often located in areas with uneven terrain, making conventional panel-type firebreaks poorly adaptable. The rigid structure of the panels makes it difficult to conform to irregular ground, easily creating gaps between the firebreak and the ground, thus reducing fire resistance. Furthermore, transporting and installing the panels in complex terrain becomes extremely difficult, requiring significant manpower and time, severely impacting the efficiency of fire prevention and suppression. These problems directly affect the effectiveness and timeliness of fire isolation, making the rapid and efficient containment of forest and grassland fires a pressing technical challenge.

[0063] Figure 1 This is a structural schematic diagram of a forest and grassland fire prevention and flame retardant device provided in this application. Figure 2 for Figure 1 The diagram shows the structure of the annular support frame and the first flexible connecting component of the forest and grassland fire prevention and flame retardant device. Figure 1 and Figure 2 As shown, to solve the above problems, this application provides a forest and grassland fire prevention and flame retardant device, including a barrel-shaped telescopic firewall 1. The barrel-shaped telescopic firewall 1 includes annular support frames 11, a first flexible connecting component 12, a first ground fixing component 13, a first fireproof cloth 14, a second fireproof cloth 15, and a third fireproof cloth 16. There are multiple annular support frames 11, which are arranged sequentially. The first flexible connecting component 12 connects every two adjacent annular support frames 11 and makes the interval between every two adjacent annular support frames 11 adjustable. The first ground fixing component 13 is disposed on at least one annular support frame 11 for fixing the barrel-shaped telescopic firewall 1 to the ground. The first fireproof cloth 14 and the second fireproof cloth 15 are disposed on both sides of the multiple annular support frames 11 for laying on the ground on the unexposed side A and the fire-facing side B of the barrel-shaped telescopic firewall 1. The third fireproof cloth 16 is disposed on the side of the multiple annular support frames 11 facing the fire-facing side B of the barrel-shaped telescopic firewall 1.

[0064] The barrel-shaped telescopic firewall 1 achieves telescopic movement by adjusting the spacing between multiple annular support frames 11. Specifically, the barrel-shaped telescopic firewall 1 can be circular, and the annular support frames 11 can be circular rings. In practice, the barrel-shaped telescopic firewall 1 is not limited to a circle; it can also be an elliptical or irregular annular structure.

[0065] The ring-shaped support frame 11 can be made of metal materials to provide good and stable support for the forest and grassland fire prevention and flame retardant device.

[0066] The first flexible connecting component 12 is flexible, thus enabling the annular support frame 11 to move freely in both the horizontal and vertical directions. This allows the barrel-shaped telescopic firewall 1 to extend and retract; when extended, the barrel-shaped telescopic firewall 1 is in a fire-retardant state, and when retracted, it is in a retracted state.

[0067] The method of using the forest and grassland fire prevention and flame retardant device according to this application embodiment is as follows:

[0068] When forest and grassland fire prevention and flame retardant devices are applied to forest and grassland fire prevention, multiple annular support frames 11 are sequentially spaced, and the first ground fixing component 13 is fixed to the ground, allowing the barrel-shaped telescopic firewall 1 to extend and be in a fire-retardant state. The first fireproof cloth 14 and the second fireproof cloth 15 are laid on the ground on both sides of the annular support frames 11, which can smother and extinguish ground flames. On the one hand, because the multiple annular support frames 11 are sequentially spaced, they can form multiple independent, liftable support positions with the ground. Furthermore, because the bottom of the annular support frames 11 has a small contact area with the ground, the forest and grassland fire prevention and flame retardant device is easily adapted to uneven terrain environments such as grasslands, sand dunes, deserts, shrublands, and woodlands, forming good support with the ground. On the other hand, the third fireproof cloth 16 is unfolded on the fire-facing side B of the multiple annular support frames 11 facing the barrel-shaped telescopic firewall 1, which can block ground flames. Using both smothering and blocking methods for fire prevention and flame retardancy can achieve efficient fire prevention and flame retardancy.

[0069] When the forest and grassland fire prevention and flame retardant device is in standby mode, multiple ring-shaped support frames 11 are arranged in close succession, so that the barrel-shaped telescopic firewall 1 is retracted and in a retracted state. Because the barrel-shaped telescopic firewall 1 is lightweight, small in size and foldable, when the forest and grassland fire prevention and flame retardant device is used in forest and grassland fire prevention, it can be carried by a single soldier and quickly set up, moved and retrieved, so as to effectively improve the fire prevention and flame retardant effect of the forest and grassland fire prevention and flame retardant device.

[0070] To address the technical issue of flexible connection between adjacent annular support frames 11 of the barrel-shaped telescopic firewall 1, the first flexible connection component 12 may include at least one of a spring 121 and a limiting pull wire 122, wherein at least one of the spring 121 and the limiting pull wire 122 connects each of two adjacent annular support frames 11.

[0071] For example, the first flexible connection component 12 includes multiple springs 121, which can be metal helical springs. These multiple helical springs connect two adjacent annular support frames 11. Under the tension of the springs 121, the multiple annular support frames 11 can automatically retract, facilitating the storage of the barrel-shaped telescopic firewall 1. Simultaneously, the extensibility of the springs 121 allows the distance between the annular support frames 11 to be adjusted within a certain range to adapt to different terrains or usage requirements.

[0072] The metal helical spring and the ring support frame 11 can be connected by snap-fit, bolt fixing or welding.

[0073] For example, the first flexible connection component 12 includes a limiting wire 122, which is connected to each annular support frame 11. The maximum spacing between two adjacent annular support frames 11 is limited based on the length of the limiting wire 122 between each pair of adjacent annular support frames 11. Taking five annular support frames 11 as an example, the length of the limiting wire 122 is 5m, and the limiting wire 122 is connected to one annular support frame 11 every 1m. Therefore, when the barrel-shaped telescopic firewall 1 extends, the maximum spacing between two adjacent annular support frames 11 is 1m, and the extended length of the barrel-shaped telescopic firewall 1 is 5m.

[0074] The limiting pull wire 122 can be a metal wire, such as steel wire. The number of limiting pull wires 122 is not limited to one, but can be multiple, with multiple limiting pull wires 122 arranged around the inner wall of the annular support frame 11. For example, there are four limiting pull wires 122, which are respectively arranged at the top, bottom, left, and right positions of the inner wall of the annular support frame 11.

[0075] The metal wire and the ring support frame 11 can be connected by snap-fit, bolt fixing or welding.

[0076] The limiting wire 122 and spring 121 can be individually installed on the annular support frame 11. Alternatively, the limiting wire 122 and spring 121 can be combined and both installed on the annular support frame 11. The spring 121 provides initial tension and cushioning, while the limiting wire 122 acts as a restraint when the spring 121 reaches its maximum elongation, preventing excessive stretching. This combined design ensures both the flexibility of the connection and the stability of the overall structure. Furthermore, this flexible connection design improves the wind resistance of the forest and grassland fire prevention and flame retardant device. When encountering strong winds, the spring 121 can absorb some of the wind force, reducing the impact on the overall structure. The limiting wire 122 can prevent excessive spacing between the frames, avoiding structural deformation or damage caused by wind.

[0077] In the implementation of this application, there is also the problem of how to fix the barrel telescopic firewall 1 to the ground. In some embodiments, the first ground fixing component 13 includes: at least one first ground pull rope 131 and at least one second ground pull rope 132; the first end of the at least one first ground pull rope 131 is connected to the annular support frame 11 on the first side of the barrel telescopic firewall 1, and the second end of the at least one first ground pull rope 131 is used to fix it to the ground; the first end of the at least one second ground pull rope 132 is connected to the annular support frame 11 on the second side of the barrel telescopic firewall 1, and the second end of the at least one second ground pull rope 132 is used to fix it to the ground.

[0078] The first ground tension rope 131 and the second ground tension rope 132 can be made of high-strength nylon rope or steel wire rope to ensure sufficient tensile strength and durability. The number of tension ropes can be adjusted according to the size of the barrel-shaped telescopic firewall 1 and the expected external forces, typically with at least two ropes on each side to provide sufficient stability. For example, in some embodiments, there are three first ground tension ropes 131 and three second ground tension ropes 132. The first ends of the three first ground tension ropes 131 are connected to the upper, left, and right positions of the annular support frame 11 on the first side of the barrel-shaped telescopic firewall 1, and the second ends of the three first ground tension ropes 131 are fixed to the ground on the first side of the barrel-shaped telescopic firewall 1 in three directions: front and sides. The first ends of the three second ground tension ropes 132 are connected to the upper, left, and right positions of the annular support frame 11 on the second side of the barrel-shaped telescopic firewall 1, and the second ends of the three second ground tension ropes 132 are fixed to the ground on the second side of the barrel-shaped telescopic firewall 1 in three directions: front and sides. By setting three ropes on each side, a stable structure is formed, which effectively enhances the wind resistance of the forest and grassland fire prevention and flame retardant device.

[0079] Among the multiple annular support frames 11, the cross-section of the annular support frames 11 on both sides is larger, so as to better accommodate the tension of the first ground pull rope 131 and the second ground pull rope 132.

[0080] Figure 3 for Figure 1 The diagram shows the structure of the first and second fireproof cloths of the forest and grassland fire prevention and flame retardant device before they are deployed. Figure 4 for Figure 3 The image shows a side view of a forest and grassland fire prevention and flame retardant device. Figure 5 for Figure 1 The side view shown is of the forest and grassland fire prevention and flame retardant device in its fire prevention and flame retardant state. Figure 3 , Figure 4 and Figure 5 As shown, to solve the problem of fixing and disassembling fireproof cloth in forest and grassland fire prevention and flame retardant devices, at least one of the first fireproof cloth 14 and the second fireproof cloth 15 is detachably connected to the annular support frame.

[0081] Specifically, the first fireproof cloth 14 is disposed on the side of the annular support frame 11 facing the unexposed surface A. The bottom of the first fireproof cloth 14 is fixedly connected to the bottom of the annular support frame 11, and the top of the first fireproof cloth 14 is detachably connected to the top of the annular support frame 11 through the first zipper assembly 141. When the barrel-shaped telescopic firewall 1 is retracted and in the retracted state, the first fireproof cloth 14 covers the side of the multiple annular support frames 11 facing the unexposed surface A of the barrel-shaped telescopic firewall 1. The top of the first fireproof cloth 14 is connected to the top of the annular support frame 11 through the first zipper assembly 141. When the barrel-shaped telescopic firewall 1 is extended and in the fireproof and flame-retardant state, the top of the first fireproof cloth 14 is separated from the top of the annular support frame 11, and the first fireproof cloth 14 can be laid on the ground of the unexposed surface A of the barrel-shaped telescopic firewall 1.

[0082] Specifically, the second fireproof cloth 15 is disposed on the side of the annular support frame 11 facing the fire-facing side B. The bottom of the second fireproof cloth 15 is fixedly connected to the bottom of the annular support frame 11, and the top of the second fireproof cloth 15 is detachably connected to the top of the annular support frame 11 through the second zipper assembly 151. When the barrel-shaped telescopic firewall 1 is retracted and in the retracted state, the second fireproof cloth 15 covers the third fireproof cloth 16, and the top of the second fireproof cloth 15 is connected to the top of the annular support frame 11 through the second zipper assembly 151. When the barrel-shaped telescopic firewall 1 is extended and in the fire-retardant state, the top of the second fireproof cloth 15 separates from the top of the annular support frame 11, and the second fireproof cloth 15 can be laid on the ground of the fire-facing side B of the barrel-shaped telescopic firewall 1.

[0083] In practical applications, this design solves the problem of fixing and disassembling fireproof cloth in forest and grassland fire prevention and retardant devices. By combining the bottom fixed connection and the top detachable connection of the first fireproof cloth 14 and the second fireproof cloth 15, the stability of the first fireproof cloth 14 and the second fireproof cloth 15 during use is ensured, while also improving the convenience of storing, carrying, and deploying the forest and grassland fire prevention and retardant device. For example, when fire prevention is needed, simply unzip the first zipper assembly 141 at the top of the first fireproof cloth 14 and the second zipper assembly 151 at the top of the second fireproof cloth 15 to easily lay the first fireproof cloth 14 and the second fireproof cloth 15 on the ground. This greatly reduces the deployment time of the forest and grassland fire prevention and retardant device and improves fire prevention efficiency.

[0084] Figure 6 for Figure 1 The diagram shows the deployment process of the first footing of the forest and grassland fire prevention and flame retardant device. Figure 7 for Figure 1 The diagram shown is a structural schematic of the first anchor of the forest and grassland fire prevention and flame retardant device. Figure 6 and Figure 7As shown, in order to further improve the installation stability of forest and grassland fire prevention and flame retardant devices in complex terrain, the first ground fixing component 13 includes: a first foot 133, which is connected to the bottom of the annular support frame 11 facing the fire-facing side B and the unfacing side A, for fixing to the ground.

[0085] Furthermore, to facilitate the fixing and storage of the first foot 133 in the forest and grassland fire prevention and flame retardant device, the first foot 133 includes: a first side wall 1331, a second side wall 1332, and a bottom wall 1333. The bottom wall 1333 connects the first side wall 1331 and the second side wall 1332, forming a groove between the first side wall 1331 and the second side wall 1332. The first side wall 1331 and the first side of the annular support frame 11, and the second side wall 1332 and the second side of the annular support frame 11 are rotatably connected on the same axis, so that the first foot 133 is rotatably connected to the annular support frame 11. When the first foot 133 rotates relative to the annular support frame 11 to the locking state, the annular support frame 11 extends into the groove. The bottom wall 1333 is provided with at least one opening 1334. When the first foot 133 rotates relative to the annular support frame 11 to the open state, the annular support frame 11 is dislodged from the groove. The at least one opening 1334 is used for fixing to the ground through a connector.

[0086] When storage is required, the first foot 133 can be rotated to the locking state, and the ring support frame 11 can be inserted into the groove to achieve compact storage, which is convenient for transportation and storage.

[0087] When needed, the first foot 133 can be rotated to the open position, and the annular support frame 11 disengages from the groove. The opening 1334 on the bottom wall 1333 secures the first foot 133 to the ground via a connector.

[0088] Figure 8 for Figure 1 The diagram shows the structure of the first side of the forest and grassland fire prevention and flame retardant device. Figure 9 for Figure 1 The diagram shown is a structural schematic of the second side of the forest and grassland fire prevention and flame retardant device. Figure 8 and Figure 9 As shown in some embodiments of this application, the forest and grassland fire prevention and flame retardant device is a modular design, and multiple barrel-shaped telescopic firewalls 1 can be assembled with each other. The outer walls of the annular support frame 11 on both sides of the barrel-shaped telescopic firewall 1 are respectively provided with a first docking structure 191 and a second docking structure 192, so that the first docking structure 191 of one barrel-shaped telescopic firewall 1 is connected to the second docking structure 192 of another barrel-shaped telescopic firewall 1 adjacent to it.

[0089] The first mating structure 191 can be a snap fastener with a cap, and the second mating structure 192 can be a matching slot. The first side of the slot is larger than the size of the cap, allowing the cap to be inserted, while the second side of the slot is smaller than the size of the cap. After the cap is inserted into the first side of the slot, one barrel-shaped telescopic firewall 1 is rotated while the other barrel-shaped telescopic firewall 1 remains stationary. The cap slides from the first side of the slot to the second side and is then snapped into place. In this way, two adjacent barrel-shaped telescopic firewalls 1 can be quickly connected through the cooperation of the snap fastener and the slot.

[0090] Specifically, there can be multiple first docking structures 191 and multiple second docking structures 192, with the multiple first docking structures 191 and multiple second docking structures 192 surrounding the outer wall of the annular support frame 11. For example, there are four first docking structures 191 and four second docking structures 192, located at the top, bottom, left, and right positions of the annular support frame 11.

[0091] Figure 10 This is a schematic diagram of the fire-facing surface B of another forest and grassland fire prevention and flame-retardant device provided in this application. Figure 11 This is a schematic diagram of the structure of the unexposed surface A of another forest and grassland fire prevention and flame retardant device provided in this application. Figure 12 for Figure 11 The diagram shows the disassembled structure of a forest and grassland fire prevention and flame retardant device. Figure 13 for Figure 11 The diagram shows the structural schematic of the triangular firewall of the forest and grassland fire prevention and flame retardant device in its folded state. Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown in the above embodiment, the third fireproof cloth 16 of the barrel-shaped telescopic firewall 1 plays a role in blocking open flames. The third fireproof cloth 16 constitutes the first-level fireproof surface of the forest and grassland fire prevention and flame retardant device. In the following embodiment, the forest and grassland fire prevention and flame retardant device also includes a triangular firewall 2 that can be used in combination with the barrel-shaped telescopic firewall 1 to further improve the fire prevention and flame retardant effect.

[0092] The triangular firewall 2 includes: a folding frame 21, a second flexible connection component 22, and a fourth fireproof cloth 23. The fourth fireproof cloth 23 can cooperate with the third fireproof cloth 16 of the barrel-shaped telescopic firewall 1 to form a higher firewall, effectively blocking the spread of fire.

[0093] The folding frame 21 comprises multiple folding frames 21, corresponding to the number of annular support frames 11. These folding frames 21 are arranged sequentially at intervals. Each folding frame 21 includes: a support leg 211, a first folding leg 212, a second folding leg 213, and a third folding leg 214. The first end of the first folding leg 212 is rotatably connected to the top of the support leg 211. The first end of the second folding leg 213 is rotatably connected between the top and bottom of the support leg 211. The first end of the third folding leg 214 is rotatably connected between the top and bottom of the support leg 211. A second flexible connecting component 22 connects the support legs 211 of two adjacent folding frames 21 to limit the spacing between adjacent folding frames 21. The top of the annular support frame 11 is provided with a first receiving portion 17 and a second receiving portion 18. 7 is used to connect with the second end of the first folding leg 212, and the second receiving part 18 is used to connect with the second end of the second folding leg 213. When the first receiving part 17 is connected with the second end of the first folding leg 212, and the second receiving part 18 is connected with the second end of the second folding leg 213, the first folding leg 212, the second folding leg 213 and the supporting leg 211 form a triangular support structure. The second end of the third folding leg 214 and the second end of the supporting leg 211 are used to support the ground on the unexposed side A. When the second end of the third folding leg 214 and the second end of the supporting leg 211 are supported on the ground, the second end of the third folding leg 214 tilts and unfolds towards the side of the barrel-shaped telescopic firewall 1, and the second end of the supporting leg 211 tilts and unfolds away from the side of the barrel-shaped telescopic firewall 1. The fourth fireproof cloth 23 is disposed on the first folding leg 212 of the multiple folding frames 21.

[0094] In some embodiments, the second flexible connection component 22 includes a first connecting line and a second connecting line. The first connecting line connects the top of the support legs 211 of two adjacent folding frames 21, and the second connecting line connects the middle of the support legs 211 of two adjacent folding frames 21, so as to limit the spacing between each pair of adjacent folding frames 21.

[0095] In some embodiments, the second flexible connection component 22 includes a third connection line that connects the first folding legs 212 (such as the bottom of the first folding legs 212) of two adjacent folding skeletons 21 to limit the spacing between each pair of adjacent folding skeletons 21.

[0096] Understandably, the second flexible connection component 22 is not limited to including at least one of the first, second, and third connecting lines, i.e., it can limit the spacing between each pair of adjacent folded skeletons 21.

[0097] The folding frame 21 can be folded and unfolded. When the first folding leg 212, the second folding leg 213, and the third folding leg 214 are folded toward the supporting leg 211, the folding frame 21 is in a folded state for easy carrying and transport. When the first folding leg 212, the second folding leg 213, and the third folding leg 214 are unfolded relative to the supporting leg 211, the folding frame 21 is in an unfolded state. The folding frame 21 can be assembled with the barrel-shaped telescopic firewall 1. The third fireproof cloth 16 and the fourth fireproof cloth 23 are connected to provide a secondary fireproof surface to further improve the fireproof effect.

[0098] The method of using the triangular firewall 2 in this embodiment is as follows:

[0099] When forest and grassland fire prevention and flame retardant devices are applied to forest and grassland fire prevention, and a large fire requires the erection of a triangular fire wall 2, the barrel-shaped telescopic fire wall 1 can be erected first. Then, the first folding leg 212, the second folding leg 213, and the third folding leg 214 are unfolded. The first receiving part 17 of the barrel-shaped telescopic fire wall 1 is connected to the second end of the first folding leg 212, and the second receiving part 18 of the barrel-shaped telescopic fire wall 1 is connected to the second end of the second folding leg 213, so that the first folding leg 212, the second folding leg 213, and the supporting leg 211 form a triangular support structure. This triangular support structure has strong support strength, enabling the triangular fire wall 2 to withstand greater wind force and fire impact. The second end of the third folding leg 214 is tilted and unfolded towards one side of the barrel-shaped telescopic fire wall 1 and supported on the ground. The bottom of the folding frame 21 is tilted and unfolded away from the barrel-shaped telescopic fire wall 1 and supported on the ground. The third folding leg 214 and the folding frame 21 are tilted and supported on the ground, forming a stable support with the ground.

[0100] To facilitate the installation of the triangular fire wall 2, the second end of the second folding leg 213 is a telescopic end, such as a telescopic rod structure or a threaded adjustment structure. During assembly, the first receiving part 17 of the barrel-shaped telescopic fire wall 1 and the second end of the first folding leg 212 are connected first. If the distance between the second receiving part 18 and the second end of the second folding leg 213 is not suitable due to uneven ground, the length of the second end of the second folding leg 213 can be adjusted to facilitate the connection between the second receiving part 18 and the second end of the second folding leg 213.

[0101] The bottom end of the support leg 211 is telescopic, for example, by adopting a telescopic rod structure or a threaded adjustment structure. During assembly, if the bottom end of the support leg 211 is difficult to form a good support with the ground due to uneven ground, the length of the bottom end of the support leg 211 can be adjusted so that the bottom end of the support leg 211 can form a stable support with the ground.

[0102] The telescopic rod structure can consist of two sleeves that can slide relative to each other. The inner sleeve has multiple positioning holes, and the outer sleeve has spring pins that engage with these positioning holes. The length of the telescopic rod can be adjusted by pressing the spring pins and sliding the inner sleeve.

[0103] Both the first receiving part 17 and the second receiving part 18 can be a plug-in structure. The second end of the first folding leg 212 and the first receiving part 17 can be plugged in and connected. The second end of the second folding leg 213 and the second receiving part 18 can be plugged in and connected.

[0104] After the triangular fire wall 2 and the barrel-shaped telescopic fire wall 1 are assembled, in order to quickly and easily connect the fourth fireproof cloth 23 and the third fireproof cloth 16, a first zipper 161 is provided at the top of the annular support frame 11, and a second zipper 162 is provided at the bottom of the fourth fireproof cloth 23. When the second end of the first folding leg 212 of the triangular fire wall 2 is connected to the first receiving part 17, the second end of the second folding leg 213 is connected to the second receiving part 18, and the second end of the third folding leg 214 and the second end of the support leg 211 are supported on the ground, the first zipper 161 can be connected to the second zipper 162 to connect the fourth fireproof cloth 23 and the third fireproof cloth 16. The design of these two zippers allows the fourth fireproof cloth 23 and the third fireproof cloth 16 to be quickly and firmly connected together.

[0105] The triangular firewall 2 also includes a second foot 25, which is connected to the second end of the third folding leg 214 and is used to connect with the first foot 133 on the bottom of the annular support frame 11 facing the unexposed surface A, and to be fixed to the ground. In this application, the connection between the second foot 25 and the first foot 133 further enhances the overall stability of the connection between the triangular firewall 2 and the barrel-shaped telescopic firewall 1.

[0106] In specific implementation, openings are provided on both the second foot 25 and the first foot 133. After the connector passes through the openings of the second foot 25 and the first foot 133, it is inserted into the ground, thereby connecting and fixing the second foot 25 and the first foot 133 to the ground.

[0107] In order to further improve the stability of the triangular firewall 2 during the implementation of this application, in some embodiments, the triangular firewall 2 further includes: at least one third ground rope 241 and at least one fourth ground rope 242; the first end of the at least one third ground rope 241 is connected to the folded frame 21 on the first side of the triangular firewall 2, and the second end of the at least one third ground rope 241 is used to fix it to the ground; the first end of the at least one fourth ground rope 242 is connected to the folded frame 21 on the second side of the triangular firewall 2, and the second end of the at least one fourth ground rope 242 is used to fix it to the ground.

[0108] The third ground guy rope 241 and the fourth ground guy rope 242 can be made of high-strength nylon rope or steel wire rope to ensure sufficient tensile strength and durability. The number of guy ropes can be adjusted according to the size of the triangular fire wall 2 and the expected external force, usually at least two guy ropes on each side to provide sufficient stability. For example, in some embodiments, there are three third ground guy ropes 241 and three fourth ground guy ropes 242. The first ends of the three third ground guy ropes 241 are connected to the three corners of the triangular support structure on the first side of the triangular fire wall 2, and the second ends of the three third ground guy ropes 241 are fixed to the ground on the first side of the triangular fire wall 2 in three directions (front and sides). The first ends of the three fourth ground guy ropes 242 are connected to the three corners of the triangular support structure on the second side of the triangular fire wall 2, and the second ends of the three fourth ground guy ropes 242 are fixed to the ground on the second side of the triangular fire wall 2 in three directions (front and sides). By setting three guy ropes on each side, a stable structure is formed, effectively enhancing the wind resistance of the forest and grassland fire prevention and flame retardant device.

[0109] Figure 14 for Figure 11 The diagram shows the structure of the first side of the triangular firewall 2 in the forest and grassland fire prevention and flame retardant device. Figure 15 for Figure 11 The diagram shows the structure of the second side of the triangular firewall 2 in the forest and grassland fire prevention and flame retardant device. Figure 14 and Figure 15 As shown, multiple triangular firewalls 2 can be assembled together. The outer walls of the folded frame 21 on both sides of the triangular firewall 2 are respectively provided with a third docking structure 26 and a fourth docking structure 27, so that the third docking structure 26 of one triangular firewall 2 can be connected to the fourth docking structure 27 of another adjacent triangular firewall 2.

[0110] The third mating structure 26 can be a protruding buckle, and the fourth mating structure 27 can be a matching groove. In this way, two adjacent triangular firewalls 2 can be quickly connected through the cooperation of the buckle and the groove.

[0111] This approach allows multiple fire-resistant and flame-retardant devices to be connected to form a larger firewall, increasing the fire-resistant area and improving fire protection. At the same time, this modular design also increases the flexibility of the device, allowing the length and shape of the firewall to be adjusted according to actual needs, adapting to different terrains and fire conditions.

[0112] The embodiments of this application have at least the following advantages:

[0113] In the embodiments of this application, when preventing the spread of forest and grassland fires, the barrel-shaped telescopic firewall 1 can be used alone, employing both blocking and suffocation fire-retardant methods. When the fire is large, the triangular firewall 2 can be used in combination with the barrel-shaped telescopic firewall 1 to provide fire resistance against higher and more intense fires, significantly increasing the fire resistance level.

[0114] Because the first fireproof cloth 14 and the second fireproof cloth 15 on both sides of the barrel-shaped telescopic firewall 1 can be unfolded and laid flat on both sides of the barrel-shaped telescopic firewall 1, they can play a role in suffocating and extinguishing fires. Because the triangular firewall 2 is fixed by a sturdy triangular support structure, it can be used in windy weather conditions. Because the bottom of the barrel-shaped telescopic firewall 1 has a small contact area with the ground, and because each small segment of the barrel-shaped telescopic firewall 1 module is relatively short, it is suitable for fire prevention and flame retardancy in environments such as grasslands, undulating sand dunes, deserts, shrublands, woodlands, undulating mountain forests, and even other fire prevention units.

[0115] Furthermore, because the barrel-shaped telescopic firewall 1 and the triangular firewall 2 modules are lightweight, small in size, and foldable, they can be carried by a single soldier and quickly erected, moved, and retrieved, thus significantly improving the fire prevention and flame retardant effect of the forest and grassland fire prevention and flame retardant device.

[0116] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
