Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire extinguishing equipment technology, specifically to a fire extinguishing system structure with a cooling function. Background Technology
[0002] Ceiling-mounted sprinkler cooling systems are a key system widely used in building fire protection. Their main function is to effectively control fire and reduce fire damage by automatically spraying extinguishing agents or coolants. The system consists of sprinkler heads, piping systems, control systems, storage devices, and support structures. Sprinkler heads are installed in the ceiling and are responsible for evenly spraying extinguishing agents onto the danger zone when a fire occurs. The piping system is responsible for transporting the extinguishing agent from the water source or storage device to the sprinkler heads, ensuring that the spray range covers the entire area. The control system includes heat and smoke detectors and automatic control valves, which can quickly detect the fire in its early stages and automatically activate the sprinkler system. The storage device provides the necessary extinguishing agent reserves. The support structure ensures that the sprinkler equipment is installed stably and does not affect the overall layout of the building. However, at present, the piping structure of the ceiling-mounted sprinkler fire extinguishing and cooling structure is fixed. That is, when a fire occurs, the detector detects the fire, the control system activates the sprinkler valves, and the extinguishing agent is sprayed to cover the fire source area. At this time, the sprinkler heads spray water vertically downwards, but the spray range of the sprinkler heads is limited, and there are spray blind spots between adjacent pipes and sprinkler heads. The existence of these blind spots means that some areas may not receive sufficient fire extinguishing spray when a fire occurs, resulting in the fire not being controlled in time and even causing the fire to spread. Utility Model Content
[0003] The purpose of this utility model is to provide a fire extinguishing system structure with cooling function. The U-shaped liquid guide pipe in the U-shaped frame is fixed to the indoor ceiling wall by the L-shaped double pipe hanger. When fire extinguishing is required, the water pump and the self-resetting oscillating drive assembly are controlled by the motor remote controller. The water pump causes water to enter the U-shaped liquid guide pipe and several equally spaced straight diversion pipes. The self-resetting oscillating drive assembly and the pulley transmission structure cause each straight diversion pipe to reciprocate in both directions to eliminate the spray blind zone between adjacent straight diversion pipes and nozzles, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a fire extinguishing system structure with cooling function, comprising two U-shaped frames, L-shaped double-pipe hangers installed at both ends of the top wall of the U-shaped frames, and a loop-shaped liquid guide pipe installed between the two U-shaped frames. A water pump for supplying water to the loop-shaped liquid guide pipe is installed on one outer wall of one of the U-shaped frames. Several equally spaced straight diversion pipes are arranged inside the loop-shaped liquid guide pipe. Rotary joints are installed at both ends of each straight diversion pipe. The end of the rotary joint furthest from the straight diversion pipe is connected to the loop-shaped liquid guide pipe. The pipes are interconnected. Several second nozzles are installed in a straight, equally spaced array at the bottom of the straight diverter pipe. A pulley drive structure is installed between the straight diverter pipes to maintain synchronous rotation. A self-resetting oscillating drive assembly for driving one of the straight diverter pipes to reciprocate forward and reverse deflection is installed inside one of the U-shaped frames. A motor remote controller is installed at the bottom of the U-shaped frame below the self-resetting oscillating drive assembly. The output of the motor remote controller is electrically connected to the input of the self-resetting oscillating drive assembly and the water pump.
[0005] Preferably, several equally spaced first nozzles are installed at the front and rear edges of the bottom end of the spiral liquid guide tube.
[0006] Preferably, the L-shaped double-tube hanger consists of two L-shaped steel pipes welded and fixed to one side of the top wall of the U-shaped frame, and a connecting beam fixed between the two L-shaped steel pipes.
[0007] Preferably, the self-resetting yaw drive assembly includes a support frame fixed to the bottom end of one of the U-shaped frames, a motor mounted at the bottom end of the support frame, a cam mounted at the top end of the motor drive shaft, and a slide mounted slidably at the bottom of the support frame. The support frame is equipped with a hydraulic damper to prevent the slide from moving away from the cam. The top end of the slide is equipped with a gear and rack transmission structure that is interconnected with one of the straight shunt pipes. The input ends of the motor and water pump are electrically connected to the output end of the motor remote controller.
[0008] Preferably, the gear and rack transmission structure includes a driving rack fixed to one side of the top of the slide and a driven gear fixed to one end of one of the straight splitter tubes, and the driven gear and the driving rack mesh with each other.
[0009] Preferably, the pulley drive structure includes a synchronous pulley mounted on one end of the surface of the straight splitter pipe and a multi-wedge belt fitted between several synchronous pulleys.
[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: This fire extinguishing system with cooling function adopts a U-shaped frame with a loop-shaped liquid guide pipe, which is fixed to the indoor ceiling wall by an L-shaped double-pipe hanger. Combined with remote motor control, a water pump, and a self-resetting oscillating drive assembly, the dynamic adjustment of the sprinkler system is achieved. The self-resetting oscillating drive assembly and pulley transmission structure drive each straight branch pipe to rotate synchronously in both directions, allowing the nozzles to move continuously within a preset spatial range, thereby achieving dynamic coverage of the spray area. As the oscillation changes continuously, the spray range expands, the coverage area increases significantly, and blind spots are significantly reduced, ensuring that every corner is covered in the event of a fire. First, timely fire suppression spraying is achieved. Second, by utilizing a remote motor controller, operators can adjust the frequency of the straight splitter pipe and nozzle oscillation according to different fire scenarios or spatial layouts to achieve customized spray coverage. This allows for rapid adjustments under different environments and fire conditions, meeting diverse fire protection needs. Finally, fires are often unpredictable, with the location of the fire source and the direction of fire spread constantly changing. Static sprinkler systems struggle to cope with these changes, easily resulting in insufficient coverage or blind spots. Oscillating motion, on the other hand, allows the nozzles to continuously move, tracking the fire source or the direction of fire spread, precisely spraying the extinguishing agent onto the fire source and its surrounding area, thereby accelerating fire suppression and reducing the possibility of fire spread.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0018] Please see Figure 1-5 The present invention provides an embodiment of a fire extinguishing system structure with cooling function, comprising two U-shaped frames 1, L-shaped double-pipe hangers 2 installed at both ends of the top wall of the U-shaped frames 1, and a loop-shaped liquid guide pipe 3 installed between the two U-shaped frames 1. A water pump 10 for conveying water to the loop-shaped liquid guide pipe 3 is installed on one outer wall of one side of one of the U-shaped frames 1. The L-shaped double-pipe hanger 2 consists of two L-shaped steel pipes welded and fixed to one side of the top wall of the U-shaped frame 1 and a connecting beam fixed between the two L-shaped steel pipes.
[0019] The inner side of the U-shaped liquid guide tube 3 is provided with several equally spaced straight diversion tubes 5. Both ends of the straight diversion tubes 5 are equipped with rotary joints 7. The end of the rotary joint 7 away from the straight diversion tube 5 is connected to the U-shaped liquid guide tube 3. Several second nozzles 6 are installed in a straight, equally spaced array at the bottom of the straight diversion tubes 5. A belt drive structure 8 is installed between the straight diversion tubes 5 to maintain synchronous rotation. A self-resetting oscillating drive assembly 9 is installed inside one of the U-shaped frames 1 to drive one of the straight diversion tubes 5 to reciprocate forward and reverse deflection. When the straight diversion tube 5 is driven to reciprocate forward and reverse rotation by the self-resetting oscillating drive assembly 9 and the belt drive structure 8, the two ends of the straight diversion tube 5 are kept unobstructed by the rotary joints 7 and the U-shaped liquid guide tube 3, so that the water source supplied by the water pump 10 can smoothly enter the straight diversion tube 5 through the U-shaped liquid guide tube 3 and the rotary joints 7 until it is sprayed out through the second nozzles 6.
[0020] A motor remote controller 11 is installed at the bottom of the U-shaped frame 1 below the self-resetting yaw drive assembly 9. The output terminal of the motor remote controller 11 is electrically connected to the input terminal of the self-resetting yaw drive assembly 9 and the water pump 10.
[0021] Several first nozzles 4 with equal spacing are installed at the front and rear edges of the bottom of the U-shaped liquid guide pipe 3. The several first nozzles 4 at the bottom of the U-shaped liquid guide pipe 3 form a water curtain in the area below the U-shaped frame 1 to further accelerate the fire extinguishing process.
[0022] The self-resetting yaw drive assembly 9 includes a support frame 901 fixed to the bottom of one of the U-shaped frames 1, a motor 902 mounted at the bottom of the support frame 901, a cam 903 mounted at the top of the drive shaft of the motor 902, and a slide block 904 slidably mounted at the bottom of the support frame 901. A hydraulic damper 905 is installed inside the support frame 901 to prevent the slide block 904 from moving away from the cam 903. A gear and rack transmission structure connected to one of the straight shunt pipes 5 is mounted at the top of the slide block 904. The input terminals of the motor 902 and the water pump 10 are electrically connected to the output terminal of the motor remote controller 11. When the self-resetting yaw drive assembly 9 is working, it is activated by the motor remote controller 11. When motor 902 operates, it drives cam 903 to rotate. When cam 903 strikes slide 904, slide 904 drives drive rack 906 to slide. At this time, hydraulic damper 905 is in a compressed state, and driven gear 907 is driven to rotate by drive rack 906. That is, the rotating end of rotary joint 7 connected to drive rack 906 and straight diverter pipe 5 are driven to rotate. When cam 903 separates from slide 904, hydraulic damper 905 pushes slide 904 and drive rack 906 to reset, and then straight diverter pipe 5 flips to realize the reciprocating forward and reverse deflection of straight diverter pipe 5 and second nozzle 6, so as to cover a larger area, reduce dead angles, and improve the comprehensiveness of fire extinguishing.
[0023] The gear and rack transmission structure includes a driving rack 906 fixed on one side of the top of the slide 904 and a driven gear 907 fixed on one end of one of the straight split pipes 5. The driven gear 907 and the driving rack 906 mesh with each other. The belt drive structure 8 includes a synchronous pulley installed on one end of the surface of the straight split pipe 5 and a multi-wedge belt fitted between several synchronous pulleys.
[0024] Adjacent straight shunt pipes 5 are connected by a pulley drive structure 8, meaning that multiple pipes share the driving power from the self-resetting yaw drive assembly 9, ensuring the synchronization of their actions.
[0025] In this embodiment, during use, the operator first confirms that the U-shaped liquid guide pipe 3, the L-shaped double-pipe hanger 2, and several straight diversion pipes 5 are intact, without cracks, blockages, or leaks. The operator checks if the second nozzle 6 is clean, ensuring it is unobstructed and provides good spraying. The operator also confirms that the water pump 10 is in normal working order, the power connection is secure, the self-resetting oscillating drive assembly 9 and the pulley drive structure 8 are operating normally without jamming or abnormal noise, and the connection between the motor remote controller 11 and the water pump 10 and the self-resetting oscillating drive assembly 9 is normal and communication is smooth. The operator then starts the water pump 10 and the self-resetting oscillating drive assembly 9 via the motor remote controller 11. The water pump 10 allows water to enter the U-shaped liquid guide pipe 3 and several straight diversion pipes 5, which spray out from the second nozzle 6 at the bottom of the straight diversion pipe 5. The operator then sets the motion parameters of the self-resetting oscillating drive assembly 9 via the motor remote controller 11. If the location of the fire source is known... The self-resetting oscillation drive assembly 9 can adjust the oscillation direction of each straight diverter pipe 5, so that the second nozzle 6 faces the fire source or the area where the fire may spread. If the location of the fire source is unknown and a large area of water spray is required, the self-resetting oscillation drive assembly 9 drives one of the straight diverter pipes 5 to reciprocate forward and reverse, so that the second nozzle 6 moves continuously in space. The other straight diverter pipes 5 move together under the drive of the pulley transmission structure 8. At this time, the staff should closely observe the smoothness of the oscillation movement of the straight diverter pipes 5 to ensure that the mechanical parts are operating normally without abnormal vibration or noise. The duration and frequency of the oscillation movement should be adjusted according to the development of the fire to ensure that the spray range covers all fire sources and flammable areas. When the fire is controlled or extinguished, the self-resetting oscillation drive assembly 9 is turned off to stop the movement of the straight diverter pipes 5 and the second nozzle 6. Then the water pump 10 is turned off to cut off the water supply and avoid unnecessary water consumption and structural damage.
