Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, and in particular to a fire sprinkler system with wide coverage. Background Technology

[0002] Hazardous chemicals are substances that are flammable, explosive, toxic, harmful, and corrosive, and can cause harm or damage to personnel, facilities, and the environment. Therefore, the safety of hazardous chemicals is of paramount importance. When a fire occurs in a chemical facility, firefighters must be on the front line fighting the fire with fire hoses.

[0003] Existing fire hoses rely on manual adjustment of water flow pattern and spray distance, and can only adjust the water flow direction through nozzles with limited angles. They cannot achieve dynamic coverage of non-uniform fire fields, resulting in insufficient fire extinguishing accuracy and a high risk of local fire reignition.

[0004] Therefore, the shortcomings of traditional fire hoses in terms of performance stability and environmental adaptability can no longer meet the high standards required for modern fire prevention and control. Utility Model Content

[0020] 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.

[0021] It should be noted that if there are directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model, they are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0022] Furthermore, if the descriptions in this utility model involve terms such as "first" or "second," they are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments:

[0024] Reference Figures 1-4 A wide-area fire sprinkler system includes a base 1, a placement groove 2 on one side of the top of the base 1, a stepper motor 3 fixedly installed in the placement groove 2, a first threaded rod 4 vertically installed on the top of the stepper motor 3, the first threaded rod 4 being threadedly connected to a threaded hole on the side of the mounting plate 5, positioning seats 6 fixedly installed on the front and rear sides of the top of the mounting plate 5, a turntable 7 rotatably installed on the top of the positioning seats 6, a clamping mechanism fixedly installed on the top of the turntable 7, the clamping mechanism being used to clamp fire hoses 10, vertical plates 11 fixedly installed on the left and right sides of the top of the mounting plate 5, a drive motor 12 fixedly installed on the outer side of the vertical plates 11, two second threaded rods 13 rotatably arranged between the two vertical plates 11, one end of the two second threaded rods 13 being fixedly connected to the output ends of the two drive motors 12 respectively, and an external rack 14 fixedly installed on the outer side of the turntable 7, the external rack 14 being meshed with the second threaded rods 13.

[0025] Optionally, the clamping mechanism includes outer fixed plates 8 fixedly installed on the left and right sides of the turntable 7. An arc-shaped clamping plate 9 is fixedly installed on the top of the outer fixed plate 8. A through hole 17 is opened on the outer side of the arc-shaped clamping plate 9. A transmission rod 18 is movably installed inside the through hole 17. A stop plate 20 is fixedly installed at one end of the transmission rod 18 located inside the arc-shaped clamping plate 9. A handle 21 is fixedly installed at the other end of the transmission rod 18. A spring 19 is sleeved on the surface of the transmission rod 18 and between the arc-shaped clamping plate 9 and the stop plate 20. The transmission rod 18 facilitates quick adjustment of the position of the stop plate 20 in conjunction with the handle 21. The spring 19 facilitates the use of its deformable characteristics to provide installation space for the fire hose 10 by utilizing its deformation characteristics. At the same time, the tension of the spring 19 can also be used to embed the stop plate 20 into the recessed area on the surface of the fire hose 10, thereby ensuring the stability of the fire hose 10 after installation.

[0026] Optionally, the top of the positioning seat 6 is provided with several slots 15, and a rotating ball 16 is movably installed inside the slot 15. The rotating ball 16 helps to reduce the mutual wear between the turntable 7 and the positioning seat 6 when the turntable 7 rotates, thereby increasing the service life of the device.

[0027] Optionally, a limiting rod 22 is fixedly installed on the other side of the base 1 opposite to the first threaded rod 4. The limiting rod 22 is movably connected to the round hole opened on the side of the assembly plate 5. A top plate 23 is fixedly installed between the top of the limiting rod 22 and the top of the first threaded rod 4. The limiting rod 22 helps to ensure the stable lifting and lowering of the assembly plate 5, avoids the influence of the rotation of the first threaded rod 4 when the assembly plate 5 is lifted and lowered, and reduces the stress on the first threaded rod 4.

[0028] Optionally, a positioning rod 24 is fixedly installed in the middle of the top of the turntable 7. The top of the positioning rod 24 is threadedly connected to a limiting plate 25. The positioning rod 24 facilitates the positioning of the turntable 7, thereby preventing the turntable 7 from dislodging from the positioning seat 6 when rotating. The limiting plate 25 facilitates further limiting of the turntable 7, thereby preventing the turntable 7 from dislodging from the positioning rod 24 when rotating, and ensuring the stability of the turntable 7 when rotating.

[0029] The working principle of this utility model:

[0030] When using this device, the two handles 21 drive the two transmission rods 18 to be pulled outwards. The transmission rods 18 drive the abutment plate 20 to move outwards synchronously. The abutment plate 20 compresses the spring 19. As the abutment plate 20 moves, the gap between the two abutment plates 20 increases. The fire hose 10 is inserted through the gap. When the handles 21 are released, the spring 19 releases tension and pushes the abutment plate 20 to cooperate with the arc-shaped clamping plate 9 to hold the fire hose 10. The stepper motor 3 drives the mounting plate 5 to rise and fall through the first threaded rod 4. The mounting plate 5 drives the fire hose 10 to rise and fall synchronously, so that the fire hose 10 can adapt to fire points at different heights and cover fire points at a greater distance. The drive motor 12 drives the turntable 7 to rotate through the second threaded rod 13 and the external rack 14. The turntable 7 drives the fire hose 10 to rotate, so that the coverage area of ​​the fire hose 10 is increased.

[0031] The present invention has thus far described the technical solution of the present invention with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
