Description

Technical Field

[0001] This utility model relates to the technical field of fire sprinkler systems, specifically a large-scale fire sprinkler system. Background Technology

[0002] Large-area fire sprinkler systems can spray water mist onto a large fire area, forming a layer of water mist that effectively isolates the fire source from the surrounding environment, preventing the fire from spreading. The water mist can quickly remove heat, lower the temperature of the fire, and slow down the fire, thereby effectively controlling its spread. The water mist sprayed by the sprinkler system can not only lower the temperature of the fire, but also evaporate the smoke, reducing the impact of smoke on firefighters and trapped people, and improving the escape success rate.

[0003] For example, a fire sprinkler device disclosed in authorization announcement number CN209361724U includes a sprinkler head body and a nozzle. The nozzle is movably installed in the inner cavity of the sprinkler head body. A connecting slider is symmetrically fixed on the outer surface of the nozzle. Water outlet holes are opened at equal intervals on the surface of the nozzle. The slider is movably locked in the inner cavity of the sprinkler head body. A support block is integrally formed at the lower end of the sprinkler head body. The connecting slider is fixed on the outer surface of the nozzle and is movably locked in the inside of the connecting groove. When fire water impacts, it prevents the nozzle from being sprayed away due to excessive impact force. When a fire occurs and the glass rod is detonated, the water flow impacts the nozzle, causing it to be locked at the bottom of the sprinkler head body. At the same time, the sealing plate is locked at the upper end of the inner cavity of the support frame, so that the water flow can flow directly downwards, expanding the fire protection range.

[0004] Although it avoids the nozzle being sprayed away due to excessive impact force, allowing the water flow to flow directly downwards, thus expanding the fire-fighting range, it is reasonably designed, easy to use, inexpensive, and its length can be freely adjusted.

[0005] However, the existing fire sprinkler systems of this type are not conducive to omnidirectional rotation and adjustment of the area for spraying, are not convenient for flexibly adjusting the spray angle for fixed-point spraying, are not convenient for large-scale long-distance mobile spraying, and are not convenient for long-distance mobile spraying with water tanks, which greatly affects the operating efficiency of the fire sprinkler system. Utility Model Content

[0006] The purpose of this utility model is to provide a large-area fire sprinkler device to solve the problems mentioned in the background art, such as the inconvenience of fire sprinkler devices for omnidirectional rotation and adjustment of the area for spraying, the inconvenience of flexibly adjusting the spray angle for fixed-point spraying, the inconvenience of convenient large-area long-distance mobile spraying, and the inconvenience of carrying water tanks for long-distance mobile spraying, which affect the operating efficiency of fire sprinkler devices.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a large-area fire sprinkler system, comprising a support plate and a water storage pan. The water storage pan is located at the bottom of the support plate, and a water tank body is installed at the top of the support plate. A power pump is installed at the bottom of the water tank body, extending to the outside of the support plate. A drain pipe is installed at the output end of the power pump, and an adapter sleeve is fitted at the bottom of the drain pipe. A water pipe is movably installed inside the adapter sleeve, and a limit plate is installed at the bottom of the water pipe. The bottom of the limit plate is connected to the water storage pan. A snap-fit ​​sleeve is fitted outside the drain pipe, and the snap-fit ​​sleeve is connected to the limit plate. The water storage tray is slidably connected to the limiting plate. A gear plate is fitted onto the end of the water storage tray near the limiting plate. A stepper motor is installed on the side wall of the snap-fit ​​sleeve. A first gear is installed on the output end of the stepper motor. The first gear meshes with the gear plate. Five sets of hollow brackets with equal spacing are installed on the side wall of the water storage tray. An electric push rod is installed inside each hollow bracket. A telescopic rod is installed on the output end of each electric push rod. A U-shaped frame is installed on the end of the telescopic rod away from the hollow bracket. A power motor is installed inside the U-shaped frame. A large gear is installed on the output end of the power motor. A U-shaped sleeve is provided on the outside of each U-shaped frame.

[0008] Preferably, each of the U-shaped sleeves has a rotating shaft installed inside, and the U-shaped sleeve is movably connected to the U-shaped frame through the rotating shaft. A small gear is installed at the center of each rotating shaft.

[0009] Preferably, the small gear meshes with the large gear, and the nozzles are installed on the side of the U-shaped sleeve away from the U-shaped frame.

[0010] Preferably, the water storage pan above the hollow support is equipped with a flexible hose, which extends through the U-shaped sleeve into the interior of the nozzle.

[0011] Preferably, a fire monitor is installed at the bottom of the water storage pan, and the water pipe extends through the limiting plate into the interior of the water storage pan.

[0012] Preferably, the support plate is provided with two sets of guide rails on its exterior, and two sets of support frames are installed on the side walls on both sides of the support plate. Each support frame is equipped with a driven wheel assembly.

[0013] Preferably, all driven wheel assemblies are slidably connected to the inside of the guide rail, and a servo motor is installed on the outer wall of the support frame on one side of the support plate.

[0014] Preferably, the output end of the servo motor is equipped with a drive wheel, and the drive wheel is slidably connected to the bottom end of the guide rail.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the fire sprinkler device not only realizes the all-round rotation and adjustment of the area by the large-area sprinkler device, which facilitates the flexible adjustment of the spray angle for fixed-point spraying, but also realizes the convenient large-area long-distance mobile spraying of the large-area fire sprinkler device, which facilitates long-distance mobile spraying with water tank and improves the operating efficiency of the fire sprinkler device.

[0016] (1) When spraying is required, water in the tank is pumped to the inside of the diversion pipe by a power pump. The diversion pipe is then connected to the water pipe via an adapter sleeve, and the water enters the water storage pan.

The power motor drives the large gear. The large gear rotates, driving the small gear to rotate, which in turn drives the rotating shaft, U-shaped sleeve, and nozzle to rotate to a certain angle, facilitating up-and-down adjustable spraying. With the cooperation of multiple rotational movements, water inside the water storage pan is transported to the fire monitor and sprayed out by the monitor. Water inside the water storage pan is also transported through a hose to the nozzle and sprayed out by the nozzle. This allows the large-area spraying device to perform all-round rotational adjustment spraying over the area, facilitating large-area spraying from multiple outlets and allowing for flexible adjustment of the spray angle for targeted spraying, thus increasing the spraying range.

[0017] (2) The active wheel is driven to rotate by the servo motor. The active wheel drives the support frame to move on the surface of the guide rail under the support of the driven wheel assembly. The support frame drives the support plate and the water tank body to move to the designated area, so as to facilitate multi-position mobile spraying and facilitate long-distance mobile spraying with water tank. This realizes convenient large-area long-distance mobile spraying of the large-area fire sprinkler device, facilitates long-distance mobile spraying with water tank, and improves the operating efficiency of the fire sprinkler device.
