Description

Technical Field

[0001] This utility model relates to the field of fire protection engineering technology, and in particular to a sprinkler fire extinguishing device used in fire protection engineering. Background Technology

[0002] Fire sprinkler systems, as important fire extinguishing equipment, are mainly divided into two categories: fixed and mobile. Fixed sprinkler systems are typically installed in fixed locations such as buildings and can automatically activate to extinguish fires in specific areas when a fire occurs. However, in some special scenarios, such as temporary construction sites, field work areas, confined spaces, or situations where the location of the fire is not fixed, fixed fire extinguishing systems may not be able to meet the fire extinguishing needs.

[0003] Portable fire sprinkler systems have emerged to address this need, offering flexibility and convenience by allowing for rapid deployment to fire scenes. However, current portable sprinkler systems still have some shortcomings. Firstly, their nozzles are typically fixed, resulting in a single, fixed direction of fire suppression and difficulty in covering blind spots. In actual firefighting operations, when encountering fire sources obscured by corners or obstacles, operators must frequently reposition the system to adjust the fire suppression direction, wasting time and energy and significantly impacting firefighting efficiency. Secondly, existing portable sprinkler systems cannot effectively disperse dense smoke near the system. At fire scenes, dense smoke not only obstructs the operator's vision, affecting their assessment of the fire and operational procedures, but can also harm their respiratory system, greatly hindering firefighting efforts. Therefore, this application proposes a sprinkler system for fire protection engineering. Summary of the Invention

[0004] The purpose of this invention is to address the problems in the prior art where the fire extinguishing direction is singular and fixed, and where personnel need to frequently move the device when encountering fire sources that are obstructed by corners or obstacles, thus affecting the fire extinguishing efficiency, and where dense smoke obstructs the user's vision. The invention proposes a sprinkler fire extinguishing device for fire protection engineering.

[0005] The technical solution of this utility model is as follows: a sprinkler fire extinguishing device for fire protection engineering, including a base plate, a water storage tank fixedly installed at the top of the base plate, a telescopic hose fixedly passing through one side of the water storage tank, a water pump installed at one end of the telescopic hose near the water storage tank, a drive box fixedly connected to the other end of the telescopic hose, a handle fixedly installed at the top of the drive box, a nozzle fixedly connected to one side of the drive box, a fixing block fixedly fitted on the nozzle, a fan fixedly installed at the end of the fixing block away from the nozzle, and a transmission device provided between the fan and the drive box.

[0006] Optionally, the transmission device includes a rotating rod rotatably connected to the drive box. Several curved plates arranged in a circular array are fixed on the curved surface of the rotating rod. The end of the rotating rod closest to the fan rotatably passes through the drive box and is fixedly fitted with a gear plate. A transmission shaft is rotatably mounted on one side of the fan. The transmission shaft is fixedly connected to the fan shaft. A bevel gear is fixedly mounted on one end of the transmission shaft. The bevel gear meshes with the gear plate.

[0007] Optionally, two long rods are fixedly installed on one side of the top of the base plate, and a crossbar is fixedly connected to the top of the two long rods. A handle is fixedly installed on the side of the crossbar away from the water storage tank.

[0008] Optionally, a rubber sleeve is fixedly installed on the handle, and the rubber sleeve is provided with anti-slip texture.

[0009] Optionally, a vertical plate is fixedly installed on the top of the base plate, and the top of the vertical plate is provided with an arc-shaped groove adapted to the telescopic hose.

[0010] Optionally, casters are provided at the four corners of the bottom of the base plate.

[0011] Optionally, a water inlet pipe is fixedly connected to the top of the water storage tank, and a pipe plug is provided at the top of the water inlet pipe.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] This utility model utilizes water to flush the bending plate, causing the bending plate to rotate in the direction of the bending plate protrusion. Through the transmission of the rotating rod and gears, the fan is activated to blow away the dense smoke near the user, preventing the dense smoke from obstructing the staff's vision and affecting their judgment and operation of the fire.

[0014] Furthermore, users can lift the nozzle and fan by the handle, and with the telescopic hose, easily adjust the angle to aim at blind spots or through obstacles to target the fire source, eliminating the need to frequently move the device to adjust the fire extinguishing direction, thus improving the device's functionality and ease of use.

[0026] Example

[0027] like Figures 1 to 2 As shown, the sprinkler fire extinguishing device for fire protection engineering proposed in this utility model includes a base plate 1, a water storage tank 2 fixedly installed at the top of the base plate 1, an inlet pipe 3 fixedly connected to the top of the water storage tank 2, and a pipe plug at the top of the inlet pipe 3. This facilitates water replenishment, and the pipe plug prevents impurities from entering the water storage tank and contaminating the water source when the inlet pipe is idle or not needed. A telescopic hose 4 is fixedly threaded through one side of the water storage tank 2, and its length can be easily adjusted to easily bypass obstacles. A vertical plate 15 is fixedly installed at the top of the base plate 1, and the top of the vertical plate 15 has an arc-shaped groove adapted to the telescopic hose 4. This groove is used to hold and fix the telescopic hose 4. A water pump 5 is installed at one end of the telescopic hose 4 near the water storage tank 2, and a drive box 6 is fixedly connected to the other end of the telescopic hose 4. A handle 16 is fixedly installed at the top of the drive box 6, and a nozzle 14 is fixedly connected to one side of the drive box 6. When the water pump 5 is started, water is drawn out, passes through the drive box 6, reaches the nozzle 14, and is sprayed out to extinguish the fire. A fixing block 13 is fixedly fitted onto the nozzle 14, and a fan 12 is fixedly installed at the end of the fixing block 13 away from the nozzle 14. The user can lift the nozzle 14 and the fan 12 by using the handle 16, and with the help of the telescopic hose 4, it is easy to adjust the angle to aim at blind spots or pass through obstacles to aim at the fire source.

[0028] Furthermore, two long rods 18 are fixedly installed on one side of the top of the base plate 1. A crossbar 19 is fixedly connected to the top of each long rod 18. A handle 20 is fixedly installed on the side of the crossbar 19 away from the water storage tank 2. Casters 17 are installed at the four corners of the bottom of the base plate 1. Workers can move the base plate by gripping the handle 20 and using the casters 17 for traction. Rubber sleeves with anti-slip textures are fixedly installed on both the handle 20 and the carrying handle 16. In firefighting situations where there may be water stains, the rubber material and surface texture increase friction, preventing slippage in wet environments or when hands are sweaty.

[0029] like Figures 3 to 4As shown, in this embodiment, a transmission device is provided between the fan 12 and the drive box 6. The transmission device includes a rotating rod 7 rotatably connected inside the drive box 6. Several curved plates 8 arranged in a circular array are fixed on the curved surface of the rotating rod 7. One end of the telescopic hose 4 is fixedly inserted through the drive box 6 and aligned with the curved plate 8 located below. Water flows over the curved plate 8, causing the curved plate 8 to rotate in the direction of the curved plate protrusion. The rotation of the curved plate 8 drives the rotating rod 7 to rotate. The end of the rotating rod 7 closest to the fan 12 rotates through the drive box 6 and is fixedly fitted with a gear disc 9. A drive shaft 11 is rotatably installed on one side of the fan 12. The drive shaft 11 is fixedly connected to the fan shaft. A bevel gear 10 is fixedly installed at one end of the drive shaft, and the bevel gear 10 meshes with the gear disc 9. The rotation of the rotating rod 7 drives the gear disc 9 to rotate, causing the bevel gear 10 to rotate. The drive shaft 11 rotates accordingly, thereby starting the fan 12 and blowing away the dense smoke near the user.

[0030] The working principle of this embodiment is as follows: When the user holds the handle 20 and moves the traction device through the universal wheels 17 to the fire scene, the water pump is started and the water is pumped out through the drive box 6 to the nozzle 14 to spray out and extinguish the fire. The water rushes over the curved plate 8, causing the curved plate 8 to rotate in the direction of the curved plate protrusion. The rotation of the curved plate 8 drives the rotating rod 7 to rotate, which drives the gear plate 9 to rotate, causing the bevel gear 10 to rotate. The transmission shaft 11 rotates accordingly, thereby starting the fan 12 to blow away the dense smoke near the user and prevent the dense smoke from obstructing the staff's vision and affecting the judgment and operation of the fire.

[0031] Users can lift the nozzle 14 and fan 12 by the handle 16, and with the help of the telescopic hose 4, it is easy to adjust the angle to aim at blind spots or pass through obstacles to aim at the fire source. This eliminates the need to frequently move the device to adjust the fire extinguishing direction, improving the functionality and ease of use of the device.

[0032] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
