[0002] A sprinkler fire extinguishing device is a fire-fighting device used for emergency treatment when a forest fire occurs. Currently, most of the sprinkler fire extinguishing devices on the market directly allow users to use a water pipe to spray water at the flames to extinguish the fire.

[0003] Fire hydrants are a common fire-fighting device, mainly including hoses, water guns or fire hydrant boxes. The hose is a hose that connects the fire hydrant and the water gun, used to transport water. The water gun is installed on the top of the hose to spray water and extinguish the fire. After the water is sprayed from the water gun, the water gun will produce a relatively large recoil. The recoil will cause the operator to constantly lower the position of the water gun during the fire-fighting process so that the ejected water can accurately fall on the burning area. Therefore, during long-term use, the operator's hand holding the water gun will become fatigued, reducing the accuracy of the position of the ejected water. Utility Model Content

[0020] according to Figure 1 , 2 As shown in Figure 3, in this embodiment, a large-space sprinkler fire extinguishing device is proposed, including a mobile vehicle 1 and a lifting plate 3. The lifting plate 3 is tilted above the mobile vehicle 1, and the lower end of the lifting plate 3 is hinged to a hinge seat 4 arranged at the upper end of the mobile vehicle 1. An adjustment mechanism for adjusting the angle between the mobile vehicle 1 and the lifting plate 3 is provided between the mobile vehicle 1 and the lifting plate 3; the angle of the lifting plate 3 is adjustable, and the mobile vehicle 1 supports the lifting plate 3 to move arbitrarily on the ground.

[0021] A rectangular limit frame is provided at one end of the lifting plate 3 at a high position, and the rectangular limit frame is fixedly connected to the lifting plate 3. A pipe nozzle 9 is provided in the rectangular limit frame, and the pipe nozzle 9 is connected to the water injection pipe 5 provided above the lifting plate 3. Both ends of the pipe nozzle 9 extend outside the rectangular limit frame, and both ends of the pipe nozzle 9 are provided with retaining rings 10 for preventing the pipe nozzle 9 from escaping from the rectangular limit frame. The water injection pipe 5 is generally fixed to the pipe nozzle 9 by a flange. When extinguishing a fire, the adjustment mechanism will adjust the angle of the lifting plate 3. When the angle of the lifting plate 3 changes, the spray height of the pipe nozzle 9 will also change, and the fire sources in different areas are extinguished. Since the lifting plate 3 is supported in conjunction with the rectangular limit frame, during the fire extinguishing process, the operator does not need to lift the pipe nozzle 9 for a long time, saving manpower.

[0022] Regarding the specific structure of the mobile vehicle 1 and how the mobile vehicle 1 moves up and down on the ground, please refer to the following description.

[0023] Two wheel brackets 16 are provided at the lower end of the mobile vehicle 1. The wheel brackets 16 are fixedly connected to the mobile vehicle 1. A mobile wheel 2 is provided on each side of the wheel bracket 16. The mobile wheel 2 is rotatably connected to the wheel bracket 16. One of the two wheel brackets 16 is a front bracket and the other is a rear bracket. Two mobile wheels 2 are provided on each wheel bracket 16. The mobile wheels 2 are rotatably connected to the left and right sides of the wheel bracket 16. When adjusting the water flow spraying position of the fire extinguishing equipment, the mobile vehicle 1 is pushed to move, and the wheel bracket 16 supports the mobile vehicle 1 to quickly transfer on the ground.

[0024] About the regulatory agencies:

[0025] The adjustment mechanism includes electric push rods 6 arranged on both sides of the mobile vehicle 1, the installation end of the electric push rod 6 is fixedly connected to the mobile vehicle 1, the output end of the electric push rod 6 is provided with a limit block 17, the limit block 17 is rotatably connected to the electric push rod 6, and the upper end surface of the lifting plate 3 is provided with an adjustment seat 7, and the adjustment seat 7 is provided with a limit groove 8. The limit block 17 is inserted into the limit groove 8 and slidably connected to the limit groove 8. The mobile vehicle 1 is provided with an electric push rod 6 on both sides, and the lifting plate 3 is also provided with a limit block 17 on both sides.

[0026] comprehensive Figure 1 and Figure 3 The specific operation mode of the regulatory mechanism is:

[0027] When the electric push rod 6 pushes the limit block 17 upward, the limit block 17 slides along the limit groove 8 and pushes the adjustment seat 7, and the lifting plate 3 rotates around the hinge seat 4, so that the rectangular limit frame is lifted upward, and the spraying height and spraying distance of the tube nozzle 9 are increased. When the electric push rod 6 pulls the limit block 17 down, the limit block 17 slides in the opposite direction along the limit groove 8 and pulls the adjustment seat 7, and the lifting plate 3 rotates in the opposite direction around the hinge seat 4, so that the rectangular limit frame falls, and the spraying height and spraying distance of the tube nozzle 9 are reduced.

[0028] About the rectangular limit frame:

[0029] The rectangular limiting frame includes a support plate 11, a cover plate 13 and two side baffles 12. The support plate 11 is fixedly connected to one end of the lifting plate 3 away from the hinge seat 4. The two side baffles 12 are fixedly connected to the two ends of the support plate 11. The two cover plates 13 are detachably connected to the upper ends of the side baffles 12. It should be noted that the diameter of the pipe nozzle 9 is smaller than the distance between the two cover plates 13, and the diameter of the retaining ring 10 is larger than the distance between the two cover plates 13.

[0030] comprehensive Figure 2 and Figure 3 , the use of the rectangular limit frame is:

[0031] After removing the cover plate 13 from the upper end of the side baffle 12, put the pipe nozzle 9 connected with the water injection pipe 5 between the two side baffles 12, and then fix the cover plate 13 to the upper end of the side baffle 12. The two retaining rings 10 limit the pipe nozzle 9 from both ends of the pipe nozzle 9 to prevent the pipe nozzle 9 from falling off from between the support plate 11 and the cover plate 13. However, the pipe nozzle 9 can still move left and right between the two side baffles 12. The advantage of such a design is that it can facilitate the operator to adjust the spray direction of the water flow of the pipe nozzle 9 according to the location of the fire source, and it is more flexible.

[0032] The connection method between the side baffle 12 and the cover plate 13 is described below.

[0033] The two ends of the cover plate 13 are equipped with fixing bolts 14, which pass through the cover plate 13 and are threadedly connected with the thread grooves provided on the upper ends of the side baffles 12. When the cover plate 13 is removed from the upper ends of the side baffles 12, the fixing bolts 14 at the two ends of the cover plate 13 can be screwed out from the thread grooves provided on the side baffles 12.

[0034] A better embodiment is that a groove 15 is provided at the upper end of the side baffle 12, and the two ends of the cover plate 13 are plugged into the two grooves 15. In the process of fixing the cover plate 13 to the upper end of the side baffle 12, the two ends of the cover plate 13 will be inserted into the grooves 15 provided at the upper end of the side baffle 12, thereby strengthening the structural strength of the joint between the cover plate 13 and the side baffle 12. When in use, the initial positioning of the cover plate 13 by the groove 15 can also facilitate the staff to screw the fixing bolt 14 into the corresponding thread groove.

[0035] The working principle of the present application: the water injection pipe 5 is generally fixed to the pipe nozzle 9 through a flange. After the cover plate 13 is removed from the upper end of the side baffle 12, the pipe nozzle 9 connected with the water injection pipe 5 is placed between the two side baffles 12, and then the cover plate 13 is fixed to the upper end of the side baffle 12. Two retaining rings 10 limit the pipe nozzle 9 from both ends of the pipe nozzle 9 to prevent the pipe nozzle 9 from falling off between the support plate 11 and the cover plate 13. The pipe nozzle 9 can still move left and right between the two side baffles 12. Water flows out from the pipe nozzle 9 through the water injection pipe 5. When extinguishing a fire, the adjustment mechanism will adjust the angle of the lifting plate 3. When the angle of the lifting plate 3 changes, the spray height of the pipe nozzle 9 will also change, and the fire sources in different areas will be effectively extinguished.
