Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fire fighting, in particular to a fire fighting nozzle with an adjustable water spraying range. Background Art
[0002] A fire sprinkler is a nozzle device used for drainage at the end of a fire pipe. When a fire occurs, water flows through the fire pipe and sprays out from the fire sprinkler, spraying water over a wide area at the fire site, thereby reducing the fire or extinguishing the fire. At the same time, the fire scene can be quickly cooled down. Existing fire sprinklers can be quickly installed on fire pipes such as fire hoses or fixed fire pipes, and use water pressure to spray a large range of water or fire extinguishing agents, which can quickly extinguish weaker fires. They are widely used in various industrial sites or residential corridors, greatly improving the fire prevention capabilities of the above scenarios and greatly improving the survival probability of workers or residents in the event of a fire.
[0003] Although the above-mentioned prior art can solve the corresponding technical problems, it still has certain defects: although the existing fire sprinkler can quickly spray high-pressure water outward, it can only spray water in a small range in the aimed direction, and the coverage area is small. If there are many fire points in the fire scene, it is easy to cause the fire intensity of other fire points to increase rapidly during the single-point spraying process, and it is difficult to quickly extinguish the fire scene with multiple fire points, so that its fire containment effect is poor and it is difficult to ensure the safety of users. Utility Model Content
[0004] The utility model aims to provide a fire sprinkler with an adjustable water spray range, a large spray range and a good effect of suppressing fires at multiple ignition points, in view of the defects and shortcomings of the prior art.

[0006] A further improvement is that the injection nozzle is a conical pipeline structure.
[0007] A further improvement is that the opening and closing ring includes a rotating ring slidably arranged on the outer wall of the inner tube and an inner groove arranged on the inner wall of the rotating ring, a sealing block is slidably arranged in the inner groove, the bottom of the sealing block slides and is closed and fits against the inner wall of the dispersed water spray pipe, and an elastic part is arranged between the top of the sealing block and the inner wall of the inner groove.
[0008] A further improvement is that: the elastic member is an elastic sheet.
[0009] A further improvement is that the elastic member is a telescopic column structure, which includes a guide cylinder arranged on the inner wall of the inner receiving groove and a sliding column with one end of the outer wall slidingly arranged on the inner wall of the guide cylinder, the other end of the sliding column is fixedly connected to the top of the blocking block, and a telescopic spring is also provided between the sliding column and the guide cylinder.
[0010] A further improvement is that the opening and closing ring also includes an anti-slip ring sleeved on the outer wall of the rotating ring.
[0011] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: when a fire with multiple ignition points occurs, the utility model can twist the opening and closing loop so that the sealing block of the opening and closing loop cannot block the dispersed water spray pipe, and then the water flow is sprayed outward through the dispersed water spray pipe, thereby making multiple streams of water sprayed from a larger range, expanding the spray range of the nozzle, and then effectively curbing the fire with multiple ignition points to ensure the safety of users.

[0017] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.
[0018] See also Figure 1-4 As shown, the technical solution adopted in this specific embodiment is: a fire sprinkler with adjustable water spray range, including a connecting pipe 1 and a transmission block 2 with one end arranged at one end of the connecting pipe 1 and connected to the connecting pipe 1, the other end of the transmission block 2 is provided with a spray nozzle 3 connected to the transmission block 2, the transmission block 2 includes an inner tube 22 arranged at one end of the connecting pipe 1 and connected to the connecting pipe 1, and an opening and closing ring 21 slidably arranged on the outer wall of the inner tube 22, a water flow cavity 24 is arranged in the inner tube 22, and a dispersed water spray pipe 23 is also arranged inside the inner tube 22, which is connected to the water flow cavity 24 and the end of which passes through the side of the inner tube 22 close to the spray nozzle 3, and the inner wall of the opening and closing ring 21 slides The opening and closing ring 21 includes a rotating ring 211 slidably arranged on the outer wall of the inner tube 22 and an inner groove 212 arranged on the inner wall of the rotating ring 211. A blocking block 213 is slidably arranged in the inner groove 212. The bottom of the blocking block 213 slides and is closed and fitted to the inner wall of the dispersed water spray pipe 23. An elastic member is arranged between the top of the blocking block 213 and the inner wall of the inner groove 212. The elastic member is a telescopic column structure. The telescopic column structure includes a guide cylinder 214 arranged on the inner wall of the inner groove 212 and a sliding column 215 with one end of the outer wall slidingly arranged on the inner wall of the guide cylinder 214. The other end of the sliding column 215 is connected to the blocking block 21 3 is fixedly connected at the top, and a telescopic spring 216 is also arranged between the sliding column 215 and the guide cylinder 214. When a large-scale spraying is required, the opening and closing ring 21 is twisted so that the inner wall of the opening and closing ring 21 no longer fits the closed dispersed water spraying pipe 23, so that the water flows from the water flow cavity 24 into the dispersed water spraying pipe 23, so that the fire sprinkler can spray water in a large range. When in use, the connecting pipe 1 is connected to the external water pipe, so that the water of the external water pipe enters the transmission block 2 through the connecting pipe 1, and flows from the water flow cavity 24 into the spray nozzle 3 to spray outward. When a fire at a single ignition point occurs, the ignition point can be quickly cooled down and extinguished by spraying outward through the spray nozzle 3, and when multiple ignition points occur, the ignition point can be extinguished by spraying outward. When a disaster occurs, the rotating ring 211 of the opening and closing ring 21 can be twisted, so that the rotating ring 211 rotates with the blocking block 213. At this time, under the influence of the longitudinal component of the torsion force, the blocking block 213 will be pressed into the inner contraction groove 212, and at the same time, the sliding column 215 slides toward the guide cylinder 214, squeezing the telescopic spring 216 to generate elastic force, so that the blocking block 213 loses its blocking effect on the dispersed water spray pipe 23, and the water flows from the water flow cavity 24 into the dispersed water spray pipe 23 and sprays outward, thereby making multiple streams of water spray from a larger range, expanding the spray range of the nozzle, and effectively curbing fires at multiple ignition points to ensure the safety of users;
[0019] The spray nozzle 3 is a conical pipe structure, which is conducive to making the water flow spray more concentrated and having a better effect on extinguishing a single fire point;
[0020] The elastic member may also be an elastic sheet, which is conducive to making installation and disassembly easier;
[0021] The opening and closing ring 21 also includes an anti-slip ring 217 sleeved on the outer wall of the rotating ring 211, which is beneficial to enhance the friction between the user's hand, thereby making the torque force transmission better and the rotation opening and closing faster.
[0022] Working principle of the utility model: When the utility model is used, the connecting pipe 1 is connected to the external water pipe, so that the water of the external water pipe enters the transmission block 2 through the connecting pipe 1, and flows from the water flow cavity 24 into the injection nozzle 3 to be sprayed outward. When a fire with a single ignition point occurs, the injection nozzle 3 can be used to spray outward to quickly cool down the ignition point and extinguish the fire. When a fire with multiple ignition points occurs, the rotating ring 211 of the opening and closing ring 21 can be twisted, so that the rotating ring 211 can rotate with the blocking block 213. At this time, Affected by the longitudinal component of the torsion, the blocking block 213 will be pressed into the retracted groove 212, and at the same time, the sliding column 215 will slide toward the guide cylinder 214, squeezing the telescopic spring 216 to generate elastic force. At this time, the blocking block 213 will lose its blocking effect on the dispersed water spray pipe 23, and then the water flow will enter the dispersed water spray pipe 23 from the water flow chamber 24 and spray outward, thereby making multiple streams of water spray out from a larger range, expanding the spray range of the nozzle, and then effectively curbing fires with multiple ignition points to ensure the safety of users.
