Description

Technical Field

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

[0002] Fire detection sprinkler systems are a core component of modern fire protection systems. They are mainly used for early fire detection, automatic alarm, and precise fire suppression. By integrating advanced sensing technology, intelligent control, and high-efficiency fire suppression components, they achieve full automation of the "detection-response-disposal" process, minimizing fire risks and losses.

[0003] Current fire safety inspections typically employ fire suppression systems that link alarms with sprinkler heads. However, traditional sprinkler heads have significant limitations: firstly, they generally use a fixed installation structure, usually pre-installed in specific locations on the ceiling or walls; secondly, the spray angle and coverage area when triggered are constrained by the pre-installed location, resulting in limited coverage at a single point. This rigid design has two major technical drawbacks: on the one hand, to achieve full-area coverage, multiple sprinkler heads must be densely arranged on the ceiling, significantly increasing installation costs and piping complexity; on the other hand, the spray direction cannot be dynamically adjusted according to the fire source location, easily creating blind spots in irregularly shaped spaces or special fire scenarios. Utility Model Content

[0004] The purpose of this utility model is to provide a fire detection and sprinkler extinguishing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire detection sprinkler extinguishing device, including a sprinkler head, and further comprising:

A connecting frame is provided between the opposite sides of the two support rods. An adjusting component is provided on one side of the top of the limit frame. The adjusting component includes a first cylinder and a first gear.

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.

[0022] Please see Figures 1-4 As shown, a fire detection sprinkler extinguishing device includes a sprinkler head 1, and further includes:

[0023] A top plate 2 is installed on the top of the spray head 1. A detection alarm device 3 is installed on one side of the spray head 1 and fixed to the top plate 2. A limit frame 4 is fixedly connected to the top of the top plate 2. A water inlet pipe 5 is connected to the top of the spray head 1.

[0024] A universal joint 6 is installed on top of the water inlet pipe 5. A water supply pipe 7 is installed on top of the universal joint 6. A limit ring 8 is fixedly connected to the surface of the water inlet pipe 5. A support rod 9 is rotatably connected inside the limit frame 4. A connecting frame 10 is provided between the opposite sides of the two support rods 9. An adjusting component 11 is provided on one side of the top of the limit frame 4. The adjusting component 11 includes a first cylinder 1101 and a first gear 1102. The top plate 2 facilitates the limiting installation of the spray head 1. The top plate 2 is the existing ceiling. The detection alarm device 3 facilitates the detection alarm operation in conjunction with the spray head 1. The limit frame 4 The adjustment component 11 is conveniently supported, while the water inlet pipe 5 facilitates the flow of water into the spray head 1. The top of the water inlet pipe 5 is movably connected to the universal head 6, allowing the water inlet pipe 5 to swing left and right. It should be noted that the connection between the universal head 6 and the water inlet pipe 5 is a universal bamboo joint pipe. Then, it is combined with the water supply pipe 7 to facilitate connection with other pipes for water supply. The limiting ring 8 facilitates the subsequent swinging of the water inlet pipe 5. The support rod 9 is fixed to the connecting frame 10, and the support rod 9 rotates inside the limiting frame 4, allowing it to swing in conjunction with the adjustment component 11 to increase the spray range.

[0025] A solenoid valve 12 is installed on the surface of the water supply pipe 7. Extension plates 13 are fixedly connected to both sides of the spray head 1. A protective railing 14 is installed at the bottom of the extension plate 13. The protective railing 14 is ring-shaped. A reinforcing block 15 is fixedly connected to one side of the limit frame 4. The bottom of the reinforcing block 15 is fixedly connected to the top plate 2. The solenoid valve 12 allows for convenient control of whether the water supply pipe 7 is supplying water. A dual triggering mechanism is achieved through the integrated smoke detection alarm device 3 and the solenoid valve 12's electrical linkage control module. When the smoke sensor detects that the ambient concentration exceeds the standard... When the internal pipeline of the sprinkler head 1 ruptures, the control system immediately activates the solenoid valve 12 to quickly deliver the extinguishing medium through the water supply pipe 7. The extension plate 13 facilitates the installation and fixation of the guardrail 14. The guardrail 14 is a ring shape that covers the surface of the sprinkler head 1, which can prevent the sprinkler head 1 from triggering the sprinkler system due to slight external impact, reducing the waste of resources caused by accidental triggering. The reinforcement block 15 is fixed between the top plate 2 and the limit frame 4, which can improve the connection strength between the two and ensure the strength of use.

[0026] The first cylinder 1101 is fixed to the top of the limiting frame 4, and the first gear 1102 is fixed to the surface of one of the support rods 9. The piston end of the first cylinder 1101 is fixedly connected to the push plate 1103. The first tooth block 1104 that meshes with the first gear 1102 is fixedly connected to one side of the push plate 1103. When the user needs the spray head 1 to swing back and forth, the first cylinder 1101 is opened, and the piston end of the first cylinder 1101 drives the push plate 1103 to move. The push plate 1103 is slidably connected to the inside of the limiting frame 4. When the push plate 1103 moves, it will drive the first tooth block 1104 to move up and down. As the first tooth block 1104 moves, it will mesh with the first gear 1102 to rotate. When the first gear 1102 rotates, it will drive the support rod 9 and cooperate with the connecting frame 10 to shake.

[0027] A fixing plate 16 is fixedly connected to one side of the connecting frame 10. A second cylinder 17 is fixedly connected to one side of the fixing plate 16. A movable plate 18 is fixedly connected to the piston end of the second cylinder 17. A toothed plate 19 is fixedly connected to one side of the movable plate 18. A second gear 20 is meshed with the bottom of the toothed plate 19. A retaining rod 21 is fixedly connected inside the second gear 20. One end of the retaining rod 21 is fixedly connected to the limiting ring 8, and the other end of the retaining rod 21 is fixedly connected to the connecting frame 10. A limiting post 22 is fixedly connected to the top of the connecting frame 10. The surface of the limiting post 22 is slidably connected to the inside of the movable plate 18. Plate 16 is fixed to one side of connecting frame 10 to facilitate support of second cylinder 17. If the user needs to swing the spray head 1 left and right, the second cylinder 17 is opened to make the movable plate 18 drive the toothed plate 19 to move back and forth. As the toothed plate 19 moves, it will mesh with the second gear 20 to rotate. When the second gear 20 rotates, it will drive the retaining rod 21 to rotate. As the retaining rod 21 rotates, it will drive the limiting ring 8 to make the spray head 1 swing left and right, thereby increasing the spray range. During the movement of the movable plate 18, the retaining rod 21, which is slidably connected inside, can improve the stability of the movable plate 18 during movement.

[0028] Working principle: First, through the integrated smoke detection alarm device 3 and solenoid valve 12 electrical linkage control module, a dual triggering mechanism is achieved. When the smoke sensor detects that the ambient concentration exceeds the standard or the internal glass of the sprinkler head 1 is broken, the control system immediately activates the solenoid valve 12, quickly delivering the extinguishing medium through the water supply pipe 7. At this time, the water flow will be delivered to the inside of the water inlet pipe 5 through the universal joint 6, and then sprayed out through the sprinkler head 1. However, both the first cylinder 1101 and the second cylinder 17 are electrically connected to the remote controller. When the user needs the sprinkler head 1 to swing back and forth, the first cylinder 1101 is opened. The piston end of the first cylinder 1101 drives the push plate 1103 to move. When the push plate 1103 moves, it will drive the first toothed block 1104 to move up and down. The movement engages the first gear 1102, causing it to rotate. When the first gear 1102 rotates, it drives the support rod 9 and the connecting frame 10 to sway. At this time, the retaining rod 21 on the connecting frame 10 works with the limiting ring 8 to drive the spray head 1 to sway back and forth. Meanwhile, if the user needs the spray head 1 to sway left and right, the second cylinder 17 is opened to make the movable plate 18 drive the toothed plate 19 to move back and forth. As the toothed plate 19 moves, it engages the second gear 20, causing it to rotate. When the second gear 20 rotates, it drives the retaining rod 21 to rotate. As the retaining rod 21 rotates, it drives the limiting ring 8 to make the spray head 1 sway left and right, thereby increasing the spray range. During the movement of the movable plate 18, the retaining rod 21, which is slidably connected inside, can improve the stability of the movable plate 18 during movement.
