Description

Technical Field

[0001] This utility model is a fire protection device for high-rise buildings, belonging to the field of building fire protection. Background Technology

[0002] To meet fire safety requirements, high-rise buildings are generally equipped with smoke alarm sensors, which are used in conjunction with automatic sprinkler systems for initial fire suppression. The sprinkler system typically consists of a sprinkler head installed around a smoke alarm. However, this system has some obvious problems: the spray range of the sprinkler head is limited and cannot be adjusted, which makes it difficult to quickly contain the fire. The fire spreads rapidly and fails to achieve the expected fire suppression effect, often resulting in major disasters. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fire protection device for high-rise buildings.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A fire protection device for high-rise buildings includes a keel box, which is connected and fixed to the ceiling keel by a side mounting plate. The bottom of the keel box has several movable openings. The interior of the keel box is equipped with a fire sprinkler mechanism and a movable adjustment mechanism. The bottom of the keel box is equipped with an electrical control box, and smoke sensors and flame sensors are respectively installed on both sides of the bottom of the electrical control box.

[0006] Furthermore, the fire sprinkler mechanism includes a fixed rod and a water supply pipe fixed inside the keel box. The fixed rod is fixed in the middle of the keel box, and several push rods are rotatably connected to the fixed rod. The bottom end of the push rod passes through the movable opening to the bottom of the keel box and is connected and fixed to the water supply shell. The bottom of the water supply shell is connected to a high-pressure nozzle. The water supply shell is connected to the water supply pipe through a water delivery hose. A solenoid valve is provided at the connection between the water supply pipe and the water supply pipeline.

[0007] Furthermore, the movable adjustment mechanism includes sliding plates that slide on both sides inside the keel box, a movable plate fixed between the two sliding plates, and a number of oblique holes adapted to the push rod on the movable plate. The top end of the push rod passes through the oblique holes to the top of the movable plate and is connected and fixed to the limiting block.

[0008] Furthermore, a fixed plate is fixed to the top of the skateboard near the side of the movable plate. One side of the fixed plate is connected to the side output end of the electric push rod through a movable connector. The electric telescopic rod is laterally fixed to the vertical plate, and the top of the vertical plate is fixed to the inner top side of the keel box.

[0009] Furthermore, the movable connector includes a T-shaped slider and a T-shaped groove. The T-shaped groove is formed on the outer side surface of the fixed plate. The T-shaped slider is slidably connected in the T-shaped groove. The end of the T-shaped slider extends through to the outside of the fixed plate and is connected and fixed to the side output end of the electric push rod.

[0010] Furthermore, the movable adjustment mechanism also includes a support frame fixed to the outer surface of the side of the water supply pipe and a rotating ring rotatably connected to the outer surface of the water supply pipe. The end of the water delivery hose near the water supply shell rests on the support frame. A counterweight rod is fixed to one side of the outer surface of the rotating ring, and the counterweight rod presses on the end of the water delivery hose near the water supply pipe.

[0011] Furthermore, the bottom of the inner walls on both sides of the keel box is provided with a sliding groove, and the end of the sliding plate is slidably connected in the sliding groove.

[0012] Furthermore, elastic shielding pads are provided on both sides of the inner wall of the movable opening, and the elastic shielding pads on both sides are stacked and staggered together.

[0013] Furthermore, the electrical control box is equipped with a microcontroller, which is electrically connected to the smoke sensor, the flame sensor, the electric push rod, and the solenoid valve.

[0014] The beneficial effects of this utility model are:

[0015] Through the design of the fire sprinkler system and the movable adjustment mechanism, the fire sprinkler system can be driven to carry out fire sprinkler operations when a fire is detected by a smoke sensor or flame sensor, so as to achieve the fire extinguishing effect. The movable adjustment mechanism drives the fire sprinkler system to swing in an arc shape, thereby increasing the fire sprinkler system's fire spray range and thus better extinguishing fires inside the building.

[0016] Through the design of the fire sprinkler system, when the smoke sensor or flame sensor detects a fire, the microcontroller in the electrical control box will activate the solenoid valve. The opening of the solenoid valve will connect the water circuit, and the water will be transported to the water supply tank through the water supply pipe and water delivery hose. Finally, it will be sprayed into the building interior through the high-pressure nozzle, thereby achieving the fire extinguishing effect.

[0017] Through the design of the active adjustment mechanism, when the smoke sensor or flame sensor detects a fire, the microcontroller in the electrical control box will activate the electric push rod. The electric push rod pushes the fixed plate to move laterally back and forth. The fixed plate pushes the inner wall of the moving plate through the sliding plate. While the moving plate is moving back and forth, it will squeeze the fixed rod through the inner wall of the inclined hole. The squeezing of the inclined surface will push the push rod to rotate around the fixed rod as the fulcrum, thereby realizing the rotation action of the high-pressure nozzle and thus improving the fire extinguishing range of the high-pressure nozzle.

[0018] Through the design of the movable adjustment mechanism, while the push rod drives the water supply shell to swing back and forth, it will pull the water delivery hose to move, thereby meeting the water delivery needs. During this process, the support frame will support the water delivery hose, and the counterweight pressure rod will drive the water delivery hose to reset and retract under the action of gravity, so as to prevent the water delivery hose from affecting the rotation of the push rod.

[0019] The movable connector, consisting of a T-shaped slider and a T-shaped groove, provides a small range of movement space between the electric push rod and the fixed plate when the electric push rods on both sides malfunction and cannot move synchronously. This allows the electric push rod to meet the power requirements for moving the fixed plate and the movable plate. Attached Figure Description

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.

[0029] Please see Figures 1-6 This utility model provides a technical solution for a fire protection device for high-rise buildings, including a keel box 1. The keel box 1 is connected and fixed to the ceiling keel via a side mounting plate 2. The bottom of the keel box 1 has several movable openings 3. The interior of the keel box 1 is equipped with a fire sprinkler mechanism and a movable adjustment mechanism. The bottom of the keel box 1 is equipped with an electrical control box 4. The bottom two sides of the electrical control box 4 are respectively equipped with smoke sensors 5 and flame sensors 6. The electrical control box 4 is equipped with a microcontroller. The microcontroller is electrically connected to the smoke sensor 5, the flame sensor 6, the electric push rod 9, and the solenoid valve. Through the design of the fire sprinkler mechanism and the movable adjustment mechanism, when the smoke sensor 5 or the flame sensor 6 detects a fire, the fire sprinkler mechanism can be driven to perform fire sprinkler operation to achieve a fire extinguishing effect. The movable adjustment mechanism drives the fire sprinkler mechanism to swing in an arc shape, thereby increasing the fire sprinkler range of the fire sprinkler mechanism and thus better extinguishing the fire inside the building.

[0030] See Figure 5The fire sprinkler system includes a fixed rod 12 and a water supply pipe 13 fixed inside the keel box 1. The fixed rod 12 is fixed in the middle of the keel box 1, and several push rods 14 are rotatably connected to the fixed rod 12. The bottom end of the push rod 14 passes through the movable opening 3 and extends to the bottom of the keel box 1, where it is connected and fixed to the water supply shell 15. The bottom of the water supply shell 15 is connected to a high-pressure nozzle 16. The water supply shell 15 is connected to the water supply pipe 13 through a water delivery hose 18. A solenoid valve is provided at the connection between the water supply pipe 13 and the water supply pipeline. Through the design of the fire sprinkler system, when the smoke sensor 5 or the flame sensor 6 detects a fire, the microcontroller in the control box 4 will activate the solenoid valve. The opening of the solenoid valve will connect the water circuit, and the water will be delivered to the water supply shell 15 through the water supply pipe 13 and the water delivery hose 18, and finally sprayed into the building interior through the high-pressure nozzle 16, thereby achieving the fire extinguishing effect.

[0031] See Figures 3-6The movable adjustment mechanism includes sliding plates 7 that slide on both sides inside the keel box 1. Slide grooves are provided at the bottom of the inner walls on both sides of the keel box 1. The ends of the sliding plates 7 are slidably connected within the slide grooves. A movable plate 10 is fixed between the two sliding plates 7. The movable plate 10 has several sets of oblique holes 11 adapted to the push rod 14. The top end of the push rod 14 passes through the oblique holes 11 and extends above the movable plate 10, connecting and fixing to a limiting block 17. A fixing plate 8 is fixed to the top of the sliding plate 7 near the movable plate 10. One side of the fixing plate 8 is connected to the side output end of the electric push rod 9 via a movable connector. The vertical plate is fixed to the top of the keel box 1. The movable connector includes a T-shaped slider and a T-shaped groove. The T-shaped groove is formed on the outer side of the side of the fixed plate 8. The T-shaped slider is slidably connected in the T-shaped groove. The end of the T-shaped slider extends to the outside of the fixed plate 8 and is connected and fixed to the side output end of the electric push rod 9. Through the movable connector composed of the T-shaped slider and the T-shaped groove, when the electric push rods 9 on both sides malfunction and cannot move synchronously, the T-shaped slider and the T-shaped groove can provide a small range of movement space between the electric push rod 9 and the fixed plate 8, thereby satisfying the needs of the electric push rod. 9. The power required to move the fixed plate 8 and the movable plate 10; the movable adjustment mechanism also includes a support frame 19 fixed to the outer surface of the side of the water supply pipe 13 and a rotating ring 20 rotatably connected to the outer surface of the water supply pipe 13. The end of the water supply hose 18 near the water supply shell 15 rests on the support frame 19. A counterweight rod 21 is fixed to one side of the outer surface of the rotating ring 20, and the counterweight rod 21 presses against the end of the water supply hose 18 near the water supply pipe 13; through the design of the movable adjustment mechanism, when the smoke sensor 5 or the flame sensor 6 detects a fire, the microcontroller in the electrical control box 4 will activate the electric push rod 9, which will push the fixed plate 8 to move laterally back and forth. The fixed plate 8 pushes the inner wall of the movable plate 10 through the sliding plate 7. While the movable plate 10 moves back and forth, it will squeeze the fixed rod 12 through the inner wall of the inclined hole 11. The squeezing of the inclined surface will push the push rod 14 to rotate around the fixed rod 12 as the fulcrum, thereby realizing the rotation of the high-pressure nozzle 16 and thus increasing the fire extinguishing range of the high-pressure nozzle 16. While the push rod 14 drives the water supply shell 15 to swing back and forth, it will pull the water supply hose 18 to move, thereby meeting the water supply needs. During this process, the support frame 19 will support the water supply hose 18, and the counterweight pressure rod 21 will drive the water supply hose 18 to reset and retract under the action of gravity, so as to prevent the water supply hose 18 from affecting the rotation of the push rod 14.

[0032] See Figure 2Both sides of the inner wall of the movable opening 3 are provided with elastic shielding pads, and the elastic shielding pads on both sides are stacked and staggered together. Through the design of the elastic shielding pads, the movable opening 3 can be shielded without affecting the rotation of the push rod 14.

[0033] The circuits and electronic components, modules and controllers, or the heat dissipation holes and maintenance doors in the space of the adapted electrical equipment are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this application does not involve improvements to software and methods or heat dissipation and maintenance.

[0034] In use, when the smoke sensor 5 or the flame sensor 6 detects a fire, the microcontroller in the control box 4 will activate the solenoid valve and the electric push rod 9. The opening of the solenoid valve connects the water circuit, and the water flows through the water supply pipe 13 and the water delivery hose 18 to the water supply shell 15, and finally sprays into the building interior through the high-pressure nozzle 16, thereby achieving the fire extinguishing effect. The electric push rod 9 pushes the fixed plate 8 to move laterally back and forth. The fixed plate 8 pushes the inner wall of the moving plate 10 through the sliding plate 7. While the moving plate 10 is moving back and forth, it will push the fixed rod 9 through the inner wall of the inclined hole 11. 2. The pressure from the inclined plane will push the push rod 14 to rotate around the fixed rod 12, thereby realizing the rotation of the high-pressure nozzle 16 and increasing the fire extinguishing range of the high-pressure nozzle 16. While the push rod 14 drives the water supply shell 15 to swing back and forth, it will pull the water supply hose 18 to move, thereby meeting the water supply needs. During this process, the support frame 19 will support the water supply hose 18, and the counterweight pressure rod 21 will drive the water supply hose 18 to reset and retract under the action of gravity, so as to prevent the water supply hose 18 from affecting the rotation of the push rod 14.
