Description

Technical Field

[0001] The utility model relates to the field of fire sprinklers, in particular to an embedded sprinkler device for fire engineering. Background Art

[0002] The main function of a fire sprinkler is to extinguish fire and prevent the spread of fire, while increasing people's safety. The working principle of a fire sprinkler system is to use temperature sensing and pressure sensing to control water spraying. When a fire occurs, the fire will cause the temperature and pressure to rise. After the fire sprinkler system senses these changes, it will automatically start the water spray device to spray water to extinguish the fire source.

[0003] After searching, Chinese patent announcement number: CN219462396U discloses an embedded building fire sprinkler device, which supports the lifting seat by arranging an organic solution glass tube so that the sprinkler head body is embedded in the inner cavity of the protective shell when there is no fire. In this way, the protective shell protects the sprinkler head body to prevent the glass tube from being damaged by bumps. Moreover, the embedded structure hides the sprinkler head body, making it more beautiful. When a fire occurs, the organic solution glass tube expands and ruptures due to high temperature and cooperates with the spring to push the sprinkler head body out of the inner cavity of the protective shell to extinguish the fire. The sprinkler head body is activated to descend by the fire principle, which is low in cost.

[0004] In the above technical solution, the sprinkler head is embedded in the protective shell and high temperature is used to make the organic solution glass tube drop down to extinguish the fire. However, this method cannot allow the sprinkler head to be embedded in the protective shell again for subsequent fire extinguishing after the fire is extinguished, so that the protective shell can only be used once or the organic solution glass tube needs to be replaced, which increases the complexity of embedding the sprinkler head and increases the cost of using the sprinkler device. Therefore, an embedded sprinkler device for fire protection engineering is proposed to solve the above problems. Utility Model Content

The slide groove 7, slider 8, positioning hole 9, insertion rod 10 and spring 11 are arranged in two groups and distributed with the central axis of the protective shell 5 as the axis of symmetry. The insertion rod 10 is inserted into the positioning hole 9 through the elasticity of the spring 11 to position the lifting seat 4 in a fixed position inside the protective shell 5, so that the sprinkler head body 1 is embedded in the inside of the protective shell 5 under normal conditions. The protective shell 5 provides shielding protection for the sprinkler head body 1, and a release component is provided inside the protective shell 5, and a protective auxiliary component is provided inside the protective shell 5.

[0034] Reference Figure 4-Figure 6The bottom end of the tension spring 6 is fixedly connected to the upper surface of the lifting seat 4, and the top end of the tension spring 6 is fixedly connected to the inner surface of the protective shell 5. The side of the slider 8 away from the slide groove 7 is fixedly connected to the outer wall of the lifting seat 4, and the outer wall of the insertion rod 10 is adapted to the inner wall of the positioning hole 9. The releasing component includes a push plate 12, which is located inside the positioning hole 9. When the insertion rod 10 is located inside the positioning hole 9, it can fit with the side wall of the push plate 12. The outer wall of the push plate 12 is adapted to the inner wall of the positioning hole 9. The top of the push plate 12 is fixedly connected to the bottom of the extrusion plate 14. A through groove 13 is provided on the surface of the slider 8. The inner wall of the through groove 13 is slidably connected to the extrusion plate 14. The upper surface of the lifting seat 4 is fixedly connected with a fixing plate 16. The side of the fixing plate 16 is fixedly connected with a capsule 15. The capsule 15 is made of expandable rubber material. The inner wall of the sac 15 is fixedly connected to a water diversion pipe 17, and part of the water diversion pipe 17 is retractable. The end of the water diversion pipe 17 away from the sac 15 passes through the inside of the threaded neck 3. The water diversion pipe 17 can transfer part of the water introduced by the threaded neck 3 into the inside of the sac 15. The protective auxiliary component includes a drain pipe 18. The outer wall of the drain pipe 18 is fixedly connected to the inner wall of the sac 15. A valve 19 is provided on the surface of the drain pipe 18. The valve 19 controls whether the drain pipe 18 discharges the water inside the sac 15. The inner wall of the chute 7 is fixedly connected to a press switch 20. When the switch end of the press switch 20 is subjected to force, the valve 19 automatically opens. When the press switch 20 lacks force, the switch end rebounds and the valve 19 automatically closes.

[0035] Reference Figure 1 and Figure 3 The outer wall of the insertion rod 10 is fixedly connected to a magnet ring 21, and the outer wall of the protective shell 5 is fixedly connected to a fixing ring 22. The magnet ring 21 is magnetically connected to the opposite side of the fixing ring 22. The magnetic cooperation between the magnet ring 21 and the fixing ring 22 can make the insertion rod 10 always remain close to one end of the positioning hole 9.

[0036] Working principle: When a fire occurs indoors, the sprinkler head body 1 introduces water through the threaded neck 3 to spray water to extinguish the fire. A small amount of water will enter the water diversion pipe 17, and the water will immediately enter the capsule 15 to expand it. After the capsule 15 expands, it applies force to the extrusion plate 14, and the extrusion plate 14 drives the push plate 12 to squeeze the insertion rod 10. The insertion rod 10 gradually moves outward and the spring 11 is stretched accordingly. After the positioning hole 9 is disengaged from the positioning of the insertion rod 10, the lifting seat 4 drives the sprinkler head body 1 to slide down instantly due to gravity. At this time, the slider 8 slides in the slide groove 7 to guide the movement of the sprinkler head body 1. After the sprinkler head body 1 is removed from the protective shell 5, it sprays water to extinguish the fire. At the same time, the slider 8 applies pressure to the press switch 20, so that the valve 19 is automatically opened, and the drain pipe 18 discharges the water inside the capsule 15 The water source stops transmitting after the fire is extinguished, and the water source inside the sac 15 is completely discharged. The sprinkler head body 1 is still outside the protective shell 5. The staff pushes the sprinkler head body 1 upward, and the valve 19 is automatically closed after the press switch 20 is released from the pressure. The slider 8 slides inside the slide groove 7. When the sprinkler head body 1 cannot be pushed, the slider 8 squeezes the insertion rod 10. When the insertion rod 10 gradually approaches the positioning hole 9, the magnet ring 21 and the fixing ring 22 are attracted by the elasticity of the spring 11, so that the insertion rod 10 is quickly inserted into the positioning hole 9 to fix the lifting seat 4, so that the sprinkler head body 1 is removed from the protective shell 5 when it needs to extinguish the fire, and is embedded in the protective shell 5 for protection when not in use, so that the sprinkler head body 1 and the protective shell 5 can be used repeatedly to reduce costs.
