Description

Technical Field

[0001] This utility model relates to the field of forest fire prevention tools, specifically a convenient fire suppression device for forest fire prevention. Background Technology

[0002] Forest fires are a major disaster that endangers forest resources and ecological security. Extinguishing the initial fire and clearing the fire site are key steps in controlling the spread of the fire. Currently, firefighters often use tools such as flame-retardant mops, flame-retardant patters, and wind-powered fire extinguishers when dealing with surface fires and shrub fires.

[0003] Reference patent document: Patent Publication No. CN202387143U, Patent Publication Date 2012-08-22, discloses a toothed forest fire prevention tool, comprising: a head and a handle. The head is formed by sequentially arranged flame-retardant strips fixed within a toothed flame-retardant fastening clamp. The other end of the toothed flame-retardant fastening clamp is fixed to the handle by a hose clamp or pin. This utility model is suitable for widespread use in forests nationwide. It has better flame-retardant strip fastening effect, is easier to replace, saves resources, and covers a larger fire suppression area than existing bundled mop-type fire-fighting tools, thus improving the efficiency of forest fire prevention and suppression.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found: Among existing forest fire fighting devices, traditional handheld fire fighting tools (such as fire-extinguishing mops and simple flame-retardant patters) mostly adopt an integrated fixed structure. Although the flame-retardant components are firmly connected to the handle, the assembly flexibility is poor. When the flame-retardant components are worn or damaged, the entire tool needs to be replaced, which not only increases the cost of consumables, but may also delay the fire response due to untimely replacement. Although some detachable fire fighting tools support component replacement, they rely on fasteners such as bolts and clips for connection. When assembling, additional tools are required, making the operation cumbersome and time-consuming. At the same time, the flame-retardant working range of existing fire fighting tools is fixed and cannot be flexibly adjusted according to the size of the fire (such as the width of the fire line and the height of the flames). Moreover, the flame-retardant mop strip is easy to get tangled with weeds and shrubs in the forest during the carrying process, which not only increases the difficulty of carrying, but may also cause wear and tear on the flame-retardant components and affect the fire fighting effect.

[0005] Therefore, this utility model provides a convenient fire-fighting device for forest fire prevention. Utility Model Content

[0006] In order to solve the problems of existing forest fire fighting devices, such as difficulty in replacing flame-retardant components, inflexible adjustment of the fighting range, and easy entanglement with vegetation when carried, the purpose of this utility model is to provide a convenient forest fire fighting device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a convenient forest fire suppression device, including a handle, the lower part of which is provided with an adjustment mechanism for easy assembly and adjustment by the user. The adjustment mechanism includes: The mounting assembly includes a mounting shell fixedly mounted on the lower part of the handle. A drive rod is rotatably mounted on the lower part of the mounting shell. Both ends of the drive rod are mounted with transmission rods via fisheye bearings. Two symmetrically distributed limiting plates are slidably engaged in the middle of the mounting shell. The other ends of the two transmission rods are mounted on the top center of the limiting plates via fisheye bearings. A mounting block is provided at the lower part of the mounting shell. A collection shell is fixedly mounted at the bottom end of the mounting block. Two sets of symmetrically distributed flame-retardant strips are provided at the lower part of the collection shell. A telescopic assembly, located in the middle of the collection shell, is used to adjust the length of the flame-retardant strip.

[0008] Preferably, the telescopic assembly includes a winding shaft rotatably mounted in the middle of the collecting shell, with a second worm gear rotatably mounted at both ends of the winding shaft, and a second worm rotatably mounted on both sides of the collecting shell. Both second worms are meshed with the second worm gears, and both sets of flame-retardant strips are wound around the outer surface of the winding shaft.

[0009] Preferably, the mounting assembly further includes a first worm gear rotatably mounted on the upper part of the mounting housing, a first worm rotatably mounted on one side of the upper part of the mounting housing, the first worm and the first worm gear meshing with each other, and the top center of the drive rod fixedly mounted on the bottom center of the first worm gear.

[0010] Preferably, the mounting block has slots on both sides of the center, and the two limiting plates are slidably locked inside the slots.

[0011] Preferably, the upper part of the mounting shell is provided with a mounting groove, and the mounting block is slidably engaged inside the mounting groove.

[0012] Preferably, two symmetrically distributed limiting rods are fixedly installed in the middle of the mounting shell, and both limiting plates are slidably locked onto the outer surface of the limiting rods.

[0013] Beneficial effects This utility model provides a convenient fire-fighting device for forest fire prevention. Compared with the prior art, it has the following advantages: 1. With this application, the operator only needs to push the mounting block into the mounting groove, and then rotate the No. 1 worm gear. The worm gear will drive the drive rod to rotate, and then the transmission rod will push the two limit plates to move precisely towards each other along the limit rod. Finally, they will be firmly locked into the slot of the mounting block, thus eliminating the need for bolts and other fasteners commonly used in traditional tools, making the installation and replacement of flame retardant strips more convenient.

[0014] 2. The operator of this application can control the simultaneous extension or retraction of the two sets of flame-retardant strips by synchronously rotating the No. 2 worm gears on both sides of the collection shell, thereby driving the No. 2 worm wheel to retract or retract, which in turn drives the winding shaft. This allows firefighters to quickly adjust the effective extinguishing range according to the size of the fire and their distance from the fire source, greatly enhancing tactical flexibility. At the same time, by collecting the flame-retardant strips after winding, it is possible to avoid the flame-retardant strips getting tangled with weeds in the forest when the operator takes the fire extinguishing device to the fire site, making it more convenient to carry.

[0021] 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 without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a convenient forest fire suppression device, including a handle 1, with an adjustment mechanism 2 at the lower part of the handle 1, which can be used to facilitate user assembly and adjustment. The adjustment mechanism 2 includes: The mounting assembly 21 includes a mounting shell 211 fixedly mounted on the lower part of the handle 1. A drive rod 215 is rotatably mounted on the lower part of the mounting shell 211. Both ends of the drive rod 215 are mounted with transmission rods 2151 via fisheye bearings. Two symmetrically distributed limiting plates 214 are slidably clamped in the middle of the mounting shell 211. The other ends of the two transmission rods 2151 are mounted on the top middle of the limiting plates 214 via fisheye bearings. A mounting block 216 is provided at the lower part of the mounting shell 211. By rotating the drive rod 215 and driving it through the transmission rods 2151, the two limiting plates 214 can be moved relative to each other, thereby clamping and fixing the lower mounting block 216 during installation. A collection shell 221 is fixedly mounted at the bottom of the mounting block 216. Two sets of symmetrically distributed flame-retardant strips 225 are provided at the lower part of the collection shell 221. The flame-retardant strips 225 are made of a composite material of glass fiber and flame-retardant cotton, which has good heat insulation and fire extinguishing effects and can quickly cover small flames. The telescopic component 22 is located in the middle of the collection shell 221 and is used to adjust the length of the flame-retardant strip 225.

[0023] The telescopic assembly 22 includes a winding shaft 224 rotatably mounted in the middle of the collection shell 221. Secondary worm gears 223 are rotatably mounted at both ends of the winding shaft 224, and secondary worms 222 are rotatably mounted on both sides of the collection shell 221. Both secondary worms 222 are meshed with the secondary worm gears 223. By simultaneously rotating the secondary worms 222 on both sides, the secondary worm gears 223 are driven to rotate, thus synchronously driving the winding shaft 224 to rotate. This causes the flame-retardant strips 225 on its outer surface to be wound and released. Both sets of flame-retardant strips 225 are wound around the outer surface of the winding shaft 224. By providing secondary worm gears 223 and secondary worms 222 at both ends of the winding shaft 224, and by simultaneously locking both ends, the winding shaft 224 can be prevented from rotating on its own during operation to the greatest extent possible, ensuring the stability of the length of the flame-retardant strips 225.

[0024] The mounting assembly 21 also includes a first worm gear 212 rotatably mounted on the upper part of the mounting housing 211. A first worm 213 is rotatably mounted on one side of the upper part of the mounting housing 211. The first worm 213 and the first worm gear 212 are meshed together. The top middle of the drive rod 215 is fixedly mounted on the bottom middle of the first worm gear 212. By setting the first worm 213 and the first worm gear 212, rotating the first worm 213 drives the first worm gear 212 to rotate, thereby driving the drive rod 215 to rotate. Under the cooperation of the transmission rod 2151 and the limiting plate 214, the drive rod 215 limits and fixes the mounting block 216. At the same time, the worm gear and worm structure has a self-locking function, which can prevent the mounting block 216 from falling off due to shaking after it is fixed.

[0025] The mounting block 216 has slots 2141 on both sides of the center. Two limiting plates 214 are slidably locked inside the slots 2141. By locking the limiting plates 214 into the slots 2141, the mounting block 216 can be fixed in a limited position, that is, the flame retardant strip 225 at the bottom can be installed and fixed.

[0026] The upper part of the mounting shell 211 has a mounting groove 2161, and the mounting block 216 is slidably locked inside the mounting groove 2161. By setting the mounting groove 2161, the mounting block 216 can be slidably locked into the mounting groove 2161 so that it can be more stable after installation.

[0027] Two symmetrically distributed limiting rods 217 are fixedly installed in the middle of the mounting shell 211. Two limiting plates 214 are slidably locked on the outer surface of the limiting rods 217. The setting of the limiting rods 217 can ensure that when the drive rod 215 rotates, the two limiting plates 214 can be driven to slide relative to or opposite to each other along the limiting rods 217 to limit and fix the mounting block 216 through the transmission rod 2151.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] During operation, the operator rotates the first worm gear 213 on the upper part of the mounting shell 211, which drives the first worm wheel 212 to rotate. The rotation of the first worm wheel 212 then drives the drive rod 215 fixed at its bottom to rotate synchronously. The rotational motion of the drive rod 215 is converted into a pushing or pulling force on the two limiting plates 214 through the transmission rod 2151 connected by the fish-eye bearings at both ends. When it is necessary to install the lower fire extinguishing component, the mounting block 216 is pushed in along the mounting groove 2161, and then the first worm gear 213 is operated to make the two limiting plates 214 move relative to each other, and finally they are locked into the slots 2141 on both sides of the mounting block 216, thus completing the firm locking of the mounting block 216 and the entire lower component. The self-locking structure formed by the first worm wheel 212 and the first worm gear 213 can effectively prevent loosening during the vibration of fire fighting operations and ensure the reliability of the connection. After the device is fixed in place, the user holds handle 1 to extinguish the fire. The flame-retardant strips 225 suspended under the collection shell 221 can be used directly to extinguish the flames. When it is necessary to adjust the effective length of the flame-retardant strips 225 according to the width or distance of the fire line, the operator can simultaneously rotate the second worm gears 222 on both sides of the collection shell 221. Each second worm gear 222 drives the second worm wheel 223 that meshes with it to rotate. The two second worm wheels 223 together drive the rotation of the winding shaft 224. The forward or reverse rotation of the winding shaft 224 can simultaneously release the two sets of flame-retardant strips 225 to extend or retract them to shorten. Similarly, the two-way self-locking mechanism composed of the second worm wheel 223 and the second worm gear 222 ensures that the flame-retardant strips 225 can be reliably locked at any extension length, and will not accidentally rewind due to force during extinguishing or dragging, thus ensuring the stability and effectiveness of the fire extinguishing operation.
