Description

Technical Field

[0001] This utility model relates to the field of spray fire extinguishing technology, specifically a spray fire extinguishing device. Background Technology

[0002] A sprinkler fire suppression system is a fire-fighting device that automatically activates based on temperature sensors and directly suppresses the spread of fire by spraying water. It is primarily used for early fire control, cooling, and flame retardancy in buildings, and is widely applicable in civil, commercial, and industrial settings to protect life and property. According to existing technologies, such as the sprinkler fire suppression device for fire engineering described in Chinese patent document CN220938890U, the disclosed technical solution adjusts the spray pattern of the sprinkler heads according to the fire intensity. During the sprinkler fire suppression process, starting motor one drives threaded rod one to rotate, thereby causing sliding mounting block one to slide laterally along the moving longitudinal plate. Starting motor two drives threaded rod two to rotate, causing sliding mounting block two to slide longitudinally along the sprinkler head. This allows the sprinkler head to move to any position indoors for better and more efficient fire suppression.

[0003] According to its publicly available technical solution, the existing technology uses a motor to drive a threaded rod to rotate, and the rotation of the threaded rod is linked to the sliding of the mounting block, thereby moving the sprinkler head and changing the coverage area of ​​the sprinkler head. Since the sprinkler head sprays water in all directions, when the fire source is singular and the fire is small, personnel cannot actively control the water source to concentrate the spray on the fire source for rapid fire extinguishing, resulting in low fire extinguishing efficiency.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 4This utility model provides the following technical solution: a sprinkler fire extinguishing device, including a sprinkler fire extinguishing device body and a ceiling 22. The sprinkler fire extinguishing device body includes a sprinkler head 1, a release mechanism 2, and a recovery assembly 3. A conical cover 16 is welded to the surface of the sprinkler head 1. The recovery assembly 3 is located above the ceiling 22. The end of the sprinkler head 1 passes through the bottom surface of the ceiling 22. A water pipe 12 is connected to the end of the sprinkler head 1. A sliding groove 27 is provided on the top surface of the ceiling 22. A fixing plate 14 is welded to the top surface of the ceiling 22. When the device is triggered, the sprinkler head 1 can be released and switched to handheld mode by pulling the rubber ball 11. After the fire is extinguished, the motor 7 can be started to complete the storage and reset of the device.

[0023] In this embodiment, the release mechanism 2 includes a spring rod 19, a short rod 15, a sliding plate 9, a first reel 4, and a second reel 5. The short rod 15 is inserted into the surface of the spray head 1 via a bearing. A torsion spring is fitted onto the surface of the short rod 15, with its two ends welded to the surface of the spray head 1 and the surface of the short rod 15, respectively. The end of the spring rod 19 passes through the surface of the short rod 15. A splash plate 17 is welded to one end of the spring rod 19, and a handle 18 is welded to the bottom surface of the splash plate 17. A stop block 20 is welded to the other end of the spring rod 19. The end of the first reel 4 is inserted into the top surface of the sliding plate 9 via a bearing. A protrusion 28 is installed on the bottom surface of the sliding plate 9, and the protrusion 28 is embedded inside the groove 27. The second reel 5 is inserted into the top of the fixed plate 14 via a bearing. On the surface of the first roller 4 and the second roller 5, circular baffles are welded. A traction rope 10 is connected to the surface of the first roller 4, and a rubber ball 11 is connected to the other end of the traction rope 10. A circular hole is opened on the surface of the ceiling 22, and the rubber ball 11 is placed inside the circular hole. One end of the water pipe 12 is connected to the surface of the second roller 5. A groove 23 is opened on the surface of the spray head 1. A U-shaped plate 25 is welded to the end of the sliding plate 9. A convex ring 24 is welded to the side of the U-shaped plate 25. The convex ring 24 is embedded in the groove 23. When the splash plate 17 moves down, the linkage block 20 moves down, causing the rubber ball 11 to fall. This pulls the rubber ball 11 and the linkage sliding plate 9 to move, thereby causing the convex ring 24 to disengage from the groove 23, thus releasing the spray head 1.

[0024] In this embodiment, the recycling component 3 includes a motor 7, a fixed disc 26, a belt 6, a first gear 8, and a second gear 13. The end of the first drum 4 is inserted into the bottom surface of the fixed disc 26 via a bearing. A fixing rod 21 is welded to the bottom surface of the fixed disc 26, and the other end of the fixing rod 21 is welded to the top surface of the sliding plate 9. The motor 7 is mounted on the top surface of the fixed disc 26, and a rotating shaft is inserted into the end of the motor 7. The end of the rotating shaft is welded to the top surface of the first drum 4 and passes through the top surface of the fixed disc 26. The first gear 8 is welded to the surface of the first drum 4, and the second gear 13 is welded to the surface of the second drum 5. The belt 6 is fitted onto the surfaces of the first gear 8 and the second gear 13. The rotation of the rotating shaft drives the first drum 4 to rotate, which in turn drives the first gear 8 to rotate. The rotation of the first gear 8, in conjunction with the rotation of the second gear 13, causes the second drum 5 to rotate, thereby realizing the collection of the traction rope 10 and the water pipe 12.

[0025] Working principle: When the device is triggered, water flows into the sprinkler head 1 through the water pipe 12. The water inside the sprinkler head 1 rushes towards the top surface of the splash plate 17, and the water on the surface of the splash plate 17 is finally sprayed into the room. The splash plate 17 is pushed downward by the water, and the displacement of the splash plate 17 causes the spring rod 19, handle 18 and stop block 20 to move synchronously. During the downward movement of the stop block 20, the rubber ball 11 falls down through the round hole. The displacement of the rubber ball 11 causes the traction rope 10 to move. During the displacement of the traction rope 10, the first drum 4 rotates. The rotation of the first drum 4 drives the first gear 8 to rotate. The rotation of the first gear 8 drives the belt 6 to rotate. The rotation of the belt 6 drives the second gear 13 to rotate. The rotation of the second gear 13 drives the second drum. 5 rotates, and during the rotation of the second drum 5, the water pipe 12 is unwound. When the traction rope 10 wrapped around the surface of the first drum 4 is completely detached, the surface of the first drum 4 is only connected to the end of the traction rope 10. At this time, the rubber ball 11 stops falling and stays above the ground. When the fire source in the room is singular and the fire is small, pull the rubber ball 11. The rubber ball 11 moves downward, causing the first drum 4 to move. During the movement of the first drum 4, the sliding plate 9 moves along the slide groove 27. The movement of the sliding plate 9 causes the U-shaped plate 25 and the convex ring 24 to move. When the convex ring 24 moves to the point of disengaging from the groove 23 of the sprinkler head 1, the inner wall of the groove 23 of the sprinkler head 1 is embedded with a magnetic strip. The sprinkler head 1 falls downward to the ground. Pick up the sprinkler head 1 and lift it upward. Pulling handle 18 causes it to rotate, which in turn rotates the splash plate 17 and spring rod 19 synchronously. When the splash plate 17 stops blocking the water source, it is displaced by the elastic force of the spring rod 19. At this time, the sprinkler head 1 forms a water jet nozzle, directing water towards the fire source. When the fire is extinguished, the water source is turned off. Releasing handle 18 causes the short rod 15 to rotate under the force of the torsion spring, which in turn drives the spring rod 19 and splash plate 17 to rotate synchronously, turning on motor 7. Motor 7 drives the first drum 4 to rotate. During the rotation of the first drum 4, the traction rope 10 is rewound around the surface of the first drum 4. The rotation of the first drum 4 drives the first gear 8 to rotate, which in turn drives the belt 6 and the second gear 13 to rotate. The rotation of the second gear 13 drives the second drum 5 to rotate. During the rotation of the second drum 5, the water pipe 12 is rewound around the surface of the second drum 5. As the traction rope 10 winds, the rubber ball 11 moves upward. During the winding of the water pipe 12, the spray head 1 moves upward. When the rubber ball 11 moves into the round hole of the ceiling 22, the top surface of the stop block 20 is below the round hole, and the groove 23 on the surface of the spray head 1 moves to the area of ​​the convex ring 24. The convex ring 24 on the side of the U-shaped plate 25 is attracted by the magnetic strip on the inner wall of the groove 23 and moves. The movement of the convex ring 24 drives the U-shaped plate 25 and the sliding plate 9 to move synchronously. When the side of the convex ring 24 moves to contact the inner wall of the groove 23, the movement stops, completing the locking of the spray head 1, and the motor 7 is turned off.The rubber ball 11 is blocked by the stop block 20 and cannot move downwards.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
