Forest and grassland fire prevention system and forest and grassland fire prevention method

Abstract

To provide a forest and grassland fire prevention system for efficiently laying and recovering fire protection fabrics in the event of a forest and grassland fire. [Solution] The forest and grassland fire protection system combines a stretchable fire-resistant fabric (1) with a fire-resistant fabric laying vehicle (3) that quickly deploys and retrieves it, enabling efficient construction of a fire wall at the scene of a fire. Furthermore, deployment can be performed by a driver and an assistant, or retrieved by a single driver, improving work efficiency. Furthermore, by ensuring that the bottom of the fire-resistant fabric (1) adheres to the ground, fire is prevented from passing underneath the fabric, improving its performance as a fire wall. The first and third protrusions (21 and 23) of the support (2), the holes (13 and 14) in the fire-resistant fabric (1), and the engaging portions (521 and 522) of the guide member (4) work together to firmly secure the fire-resistant fabric (1) to the ground, enabling rapid deployment and retrieval.

Description

[0015] A forest and grassland fire protection system according to one embodiment of the present invention will be described with reference to the drawings. In this forest and grassland fire protection system, when a forest and grassland fire breaks out, a fire-protection fabric laying vehicle 3 is driven along the periphery of the fire, fire-protection fabric 1 is deployed from the fire-protection fabric laying vehicle 3, and posts 2 are inserted into holes 13 and 14 in the fire-protection fabric 1 to lay it on the ground. After the forest and grassland fire is extinguished, the direction of the fire-protection fabric laying vehicle 3 is reversed, and the fire-protection fabric laying vehicle 3 is driven along the laid fire-protection fabric 1, and the fire-protection fabric 1 is retrieved by the fire-protection fabric laying vehicle 3. Hereinafter, the forward direction, which is the traveling direction of the fire-protection fabric laying vehicle 3, is defined as the X direction, the left-right direction, which is the width direction of the fire-protection fabric laying vehicle 3, is defined as the Y direction, and the up-down direction, which is perpendicular to both the X and Y directions, is defined as the Z direction. In the following description, the present embodiment will be described in detail, with the forward direction, which is the traveling direction of the fire-protection fabric laying vehicle 3, defined as the X direction, the left-right direction, which is the width direction of the fire-protection fabric laying vehicle 3, is defined as the Y direction, and the up-down direction, which is perpendicular to both the X and Y directions, is defined as the Z direction.

[0016] As shown in Figures 2 and 3, the forest and grassland fire protection system includes a fire protection fabric 1, a support 2, and a fire protection fabric laying vehicle 3.

[0017] As shown in FIG. 1(A), the fire-resistant fabric 1 is a stretchable fabric made of one or a combination of silicone glass fiber fire-resistant fabric, basalt fiber fabric, and aramid stainless steel wire fabric. The fire-resistant fabric 1 is a strip extending in one direction. While 80% of fire-resistant fabrics on the market are silicone glass fiber fire-resistant fabrics, the exposed glass fibers can cause lung cancer if inhaled, and stomach cancer if ingested. Therefore, in this embodiment, the fire-resistant fabric 1 can be made of a combination of flame-retardant glass fiber fabric, basalt fiber fabric, and aramid stainless steel wire fabric. The fire-resistant fabric 1 is wound around a shaft 11 to form a fire-resistant fabric roll 10. Each pair of two vertically spaced holes 13 and 14 is formed in the fire-resistant fabric 1 at a distance W1 (W1 = 7 m) in the stretching direction. The vertical width H1 of the fire-resistant cloth 1 is 1.5 m, and the hole 13 is located at a position H2 (H2 = 6 cm) below the upper edge of the fire-resistant cloth 1. The hole 14 is located at a position H3 (H3 = 6 cm) above the lower edge of the fire-resistant cloth 1.

[0018] As shown in FIG. 1(B), the support 2 is a columnar member extending in the vertical direction. The width W4 of the support 2 is 6 mm. The lower portion of the support 2 is tapered, and the length H2 of the tapered portion is 15 cm. A first protrusion 21 protruding laterally is provided above the tapered portion of the support 2. A second protrusion 22 protruding laterally is provided above the first protrusion 21. The distance H3 between the first protrusion 21 and the second protrusion 22 is 3 cm. A third protrusion 23 protruding laterally is provided above the second protrusion 22. The distance H4 between the first protrusion 21 and the third protrusion 23 is 1.38 m. The portion of the support 2 above the third protrusion 23 is inclined at a predetermined angle θ (θ = 15 degrees) with respect to the extension direction, and the height H5 of the inclined portion is 6 cm. The first protrusion 21 is for hooking onto the edge of the hole 14 when the support 2 is inserted into the lower hole 14 of the fire-resistant cloth 1. The third protrusion 23 is for hooking onto the edge of the hole 13 when the support 2 is inserted into the upper hole 13 of the fire-resistant cloth 1. The second protrusion 22 serves as a grip to be held by hand when removing the support 2 from the fire-resistant cloth 1.

[0019] As shown in Figures 2 and 3, the fire-protective fabric laying vehicle 3 includes a vehicle body 31, a plurality of tires 32 supporting the vehicle body 31, an engine serving as a drive source 33 for driving the tires 32, a front and rear drawers 35 and 36 provided on the loading platform 310 of the vehicle body 31, a guide member 4, and a driver's seat 37. The front drawer 35 is installed at the front of the loading platform 310 of the vehicle body 31, and the rear drawer 36 is installed at the rear of the loading platform 310. The front drawer 35 is a drawer on which the fire-protective fabric roll 10 is placed when the fire-protective fabric 1 is deployed. The rear drawer 36 is a drawer on which the fire-protective fabric roll 10 is rotated and wound up when the fire-protective fabric 1 is retrieved. The driver's seat 37 is provided with a chair 38, a steering wheel 39, an accelerator (not shown), a brake (not shown), and a transmission (not shown). It is assumed that the driver and assistant will work together when deploying, and that the driver will operate it alone when retrieving.

[0020] Next, the guide member 4 installed on the firestop fabric laying vehicle 3 will be described. As shown in FIGS. 4 and 5, the guide member 4 has two upright pillars 5, one in the front and one in the rear, and two guide rails 6, one in the top and one in the bottom. As shown in FIG. 4, the upright pillars 5 are generally U-shaped when viewed from the X direction, which is the traveling direction of the vehicle body. The upright pillars 5 have a first rod 51 and a second rod 52 extending parallel to each other, and a third rod 53 interposed therebetween. The length H6 of the second rod 52 is longer than the length H5 of the first rod 51. Two engaging portions 521 and 522 spaced apart vertically are provided on the surface of the second rod 52 facing the first rod 51. Note that, although the engaging portions 521 and 522 are bent into a hook shape in FIGS. 1, 2, and 4, their shape is not limited to a hook shape. For example, the engaging portions 521 and 522 may be formed as through-holes for inserting the guide rails 6 or as locking protrusions for pressing the fourth rod 61 of the guide rails 6 against them. Any shape is acceptable as long as the structure can hold the two upper and lower guide rail sections 6 in a predetermined position in the vertical direction (a position where the two guide rail sections 6 can hold and guide the fireproof cloth 1 in an unfolded state).

[0021] As shown in FIG. 5, the guide rail unit 6 has a generally L-shape as a whole when viewed from the vertical Z direction. The guide rail unit 6 includes a fourth rod 61 and a fifth rod 62 connected to one end of the fourth rod 61. As shown in FIGS. 2 and 3, the guide rail unit 6 is attached to the engaging portions 521 and 522 of the upright column 5 with the fifth rod 62 facing inward. Of the two upper and lower guide rail units 6 shown in FIGS. 2 and 3, the lower surface of the fourth rod 61 of the upper guide rail unit 6, excluding the left and right ends (portions that engage with the engaging portions 521 and 522), protrudes downward by the thickness of the engaging portions 521 and 522. As a result, when the upper guide rail unit 6 is engaged with the engaging portions 521 and 522, the portion of the lower surface of the guide rail unit 6 sandwiched between the engaging portions 521 and 522 is flush with the surfaces of the engaging portions 521 and 522, enabling smooth guidance of the fire-retarding cloth 1.

[0022] As shown in Fig. 2, when the fire-protective cloth 1 is deployed, the first rods 51 of the two uprights 5 are attached to the two connectors 351L and 352L on the left side of the front drawer 35 or to the two connectors 351R and 352R on the right side. As a result, the fire-protective cloth 1 is pulled out from the fire-protective cloth roll 10 on the front drawer 35, supported between the upper and lower guide rails 6, and guided to the rear of the fire-protective cloth laying vehicle 3. As shown in Fig. 3, when the fire-protective cloth 1 is retrieved, the direction of the fire-protective cloth laying vehicle 3 is reversed from when the fire-protective cloth 1 is deployed, and the uprights 5 are attached to the two connectors 361L and 362L on the left side of the rear drawer 36 or to the two connectors 361R and 362R on the right side. As a result, the fire-protective cloth 1 is supported between the upper and lower guide rails 6 and retrieved into the fire-protective cloth roll 10 on the rear drawer 36. Here, when the upright portions 5 are attached, the upper surfaces of the guide rail portions 6 attached to the lower engagement portions 522 of the second rods 52 of the two upright portions 5 are configured to be at the same vertical height as the loading platform 310.

[0023] Here, when the fire-resistant cloth 1 is deployed or retrieved, the second rods 52 of the two upright portions 5 and the two guide rail portions 6 attached to the engaging portions 521, 522 of the second rods 52 are located on the outside in the width direction of the fire-resistant cloth laying vehicle 3.

[0024] 6 is a flowchart showing a forest and grassland fire prevention method according to one embodiment of the present invention. As shown in FIG. 6, the forest and grassland fire prevention method includes a laying step S10 and a removal step S20.

[0025] In the laying step of step S10, in the event of a forest fire, the driver and an assistant unfold and lay the fire-resistant cloth 1. First, the fire-resistant cloth roll body 10, with the fire-resistant cloth 1 wound around an axis, is placed on the front drawer 35. In addition, a pressure bar 90 is placed between the two upper and lower engagement parts 521, 522 of the front upright part 5 of the two upright parts 5. As a result, the fire-resistant cloth 1 pulled out from the front drawer 35 goes around the pressure bar 90 and is guided between the two upper and lower guide members 4.

[0026] Next, the tip of the fire-resistant fabric 1 is hung on the guide member 4, and the support pole 2 is passed through the holes 13 and 14 at the tip side and inserted into the ground. In this state, when the driver of the fire-resistant fabric laying vehicle 3 moves the vehicle 3 forward, the fire-resistant fabric 1 is pulled, and the front drawstring 35 and the fire-resistant fabric roll 10 rotate together, and the fire-resistant fabric 1 is pulled out from the fire-resistant fabric roll 10. At this time, the driver drives the fire-resistant fabric laying vehicle 3 forward, and an assistant inserts the support poles 2 into the holes 13 and 14 of the fire-resistant fabric 1 deployed at the rear of the fire-resistant fabric laying vehicle 3 and hammers them into the ground to secure the fire-resistant fabric 1 to the ground. By utilizing the vertical flexibility of the fire-resistant fabric 1, the support pole 2 can be inserted first into the lower hole 14, and then the fire-resistant fabric 1 can be stretched and passed through the upper hole 13 through the support pole 2, achieving smooth laying work.

[0027] In the withdrawal step of step S20, after the fire is extinguished, the driver independently retrieves the fire-protective cloth 1. First, the driver reverses the direction of the fire-protective cloth laying vehicle 3, places the partially unfolded fire-protective cloth roll 10 on the rear drawer 36, and hangs the fire-protective cloth 1 on the guide member 4. In this state, the driver rotates the rear drawer 36 while moving the fire-protective cloth laying vehicle 3 forward. This pulls the fire-protective cloth 1, removing the support poles 2 that had been inserted into the ground from the ground. The fire-protective cloth 1 is then guided by the guide member 4 and the hold-down bar 90 and wound up onto the fire-protective cloth roll 10. The driver removes the support poles 2 from the fire-protective cloth 1 as the fire-protective cloth 1 passes beside the driver. This series of actions enables the driver to independently and efficiently retrieve the fire-protective cloth.

[0028] According to the forest and grassland fire protection system of this embodiment, the combination of an elastic fireproof cloth 1 and a fireproof cloth laying vehicle 3 that quickly deploys and retrieves it makes it possible to efficiently construct a fire wall at the fire scene.

[0029] In addition, the deployment work can be performed by the driver and an assistant, and the recovery work can be performed by the driver alone, improving work efficiency.

[0030] Furthermore, by making the lower part of the fireproof cloth 1 adhere to the ground, the fire is prevented from passing under the fireproof cloth, improving its performance as a fire wall.

[0031] The first protrusion 21 and third protrusion 23 of the support 2, the holes 13, 14 of the fire-resistant cloth 1, and the engagement portions 521, 522 of the guide member 4 work together to firmly fix the fire-resistant cloth 1 to the ground, while allowing for rapid laying and retrieval operations.

[0032] Furthermore, the second protrusion 22 serves to make it easier to grasp the support pole 2 when retrieving it, thereby reducing the burden on the worker and increasing safety.

[0033] Although one embodiment of the present invention has been described above, various modifications are possible. For example, as shown in Fig. 7, the pressure bar 90 in Fig. 2 may be replaced with an X-shaped pressure bar 90A. This pressure bar 90A has a first bar spanning between the engagement portion 521 on the front pillar 5 and the engagement portion 521 on the rear pillar 5, and a second bar spanning between the engagement portion 521 on the rear pillar 5 and the engagement portion 521 on the front pillar 5, with the first and second bars fixed at their intersecting positions. This modification allows for smoother guidance of the fire-retardant cloth 1. [Explanation of symbols]
