Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, and in particular to a fire sprinkler head that is easy to maintain. Background Technology

[0002] Fire sprinklers, as a key component of fire protection systems, play a vital role. In modern buildings, they are widely installed on walls or ceilings, closely connected to the fire water network, ready to activate rapidly in the event of a fire, spraying water to extinguish the flames and protect lives and property. Fire sprinklers have a long history of development, evolving and improving over hundreds of years, and have now become one of the most efficient and reliable modern fire protection technologies.

[0003] Fire sprinklers, as a key component of fire protection systems, play a vital role. In modern buildings, they are widely installed on walls or ceilings, closely connected to the fire water network, ready to activate rapidly in the event of a fire, spraying water to extinguish the flames and protect lives and property. Fire sprinklers have a long history of development, evolving and improving over hundreds of years, and have now become one of the most efficient and reliable modern fire protection technologies.

[0004] Patent document CN221206600U discloses a fire sprinkler head and fire sprinkler device that are easy to replace and maintain, belonging to the field of fire sprinkler head technology. This easy-to-replace and maintain fire sprinkler head includes a connecting assembly and a sprinkler assembly. The connecting assembly includes a pipe, a connecting plate, a clamping rod, an elastic element, and a sprinkler tube. The connecting plate has slots and connecting grooves. The sprinkler assembly includes a frame, a plug, a temperature-sensing glass bulb, and a deflector. The frame is located at the bottom end of the sprinkler tube, and one end of the plug is hinged to the sprinkler tube. By using a pipe, connecting plate, clamping rod, elastic element, and sprinkler tube, and avoiding threaded connection installation, the clamping rod secures the sprinkler tube, preventing contact between the connection point and water. This snap-fit ​​method facilitates overall disassembly, assembly, replacement, and maintenance. The frame, plug, temperature-sensing glass bulb, and deflector, along with the hinged connection between the plug and sprinkler tube, prevent waste due to plug detachment during sprinkler use, thus saving costs.

[0005] As with the prior art of the aforementioned patent, the working principle of the fire sprinkler head is the same as that of most fire sprinklers in the prior art. By breaking the temperature-sensitive glass bulb, the blockage above falls out, and then the water inside the fire pipe can spray out from the joint to achieve the spraying effect. However, this design has drawbacks. First, the blockage will fall off from the top and is not easy to find after one use. More importantly, during the spraying process, the fallen blockage will fall down with the water flow, which may cause injury to people or objects nearby. Second, the glass shards produced after the temperature-sensitive glass bulb breaks will be sprayed out with the water flow, which may also cause injury to people or objects below. Furthermore, the collection and disposal of glass shards is required during subsequent maintenance, which is quite cumbersome. Utility Model Content

[0025] Reference Figure 1-6 A fire sprinkler head that is easy to maintain includes a connector 1, two connecting brackets 3, and a deflector plate 6. A nozzle 15 is provided through the connector 1. A disassembly assembly is provided between the two connecting brackets 3 and the connector 1. A protective cylinder 7 is fixedly installed at the top of the deflector plate 6. The two connecting brackets 3 are fixedly installed on both sides of the protective cylinder 7. An abutment cylinder 13 is snapped into the inside of the protective cylinder 7. A glass rod 10 is provided between the abutment cylinder 13 and the protective cylinder 7. The bottom end of the glass rod 10 contacts the bottom end of the protective cylinder 7, and the top end of the glass rod 10 contacts the top end of the abutment cylinder 13. A sealing assembly is provided between the abutment cylinder 13 and the nozzle 15 of the connector 1. After the connector 1 is installed on the fire pipeline, when a fire occurs... When the ambient temperature reaches the critical temperature of the expansion solution inside the glass rod 10, the internal solution will squeeze the glass rod 10 to break. The glass rod 10 will break directly inside the protective cylinder 7. After the upper sealing component loses the upward limiting force of the glass rod 10, it will release the seal under the action of gravity and the water pressure inside the pipe. A large amount of water will be sprayed out from the spray nozzle 15 of the connector 1. The water flow will be sprayed out through the splash plate 6 to achieve the spraying effect required for fire fighting. After the glass rod 10 breaks, it will not leak inside the protective cylinder 7. The sealing component is fixed on the abutment cylinder 13 and will not fall off. This provides convenience for the subsequent maintenance of the device and increases the safety when the spraying conditions are triggered.

[0026] As a preferred technical solution in this embodiment, the connector 1 is provided with a threaded groove 2; the connector 1 can be locked onto the fire pipe through the threaded groove 2, making its disassembly process easier.

[0027] As a preferred technical solution of this embodiment, the disassembly assembly includes two insertion slots 4 and two fixing bolts 5 opened at the bottom of the connector 1. The top ends of the two connecting brackets 3 are inserted into the insertion slots 4 and locked by the fixing bolts 5 on both sides. The protective cylinder 7, the abutment cylinder 13 and the splash plate 6 can be disassembled and installed in a unified manner through the connecting brackets 3.

[0028] As a preferred technical solution of this embodiment, the sealing component includes a sealing member 11 fixedly installed on the top of the abutment cylinder 13, and the sealing member 11 seals the bottom of the water nozzle 15; the sealing member 11 can seal the water nozzle 15.

[0029] As a preferred technical solution of this embodiment, the sealing assembly further includes a sealing element 12, which is disposed between the sealing element 11 and the abutment cylinder 13. The sealing element 12 can increase the sealing between the water nozzle 15 and the sealing element 11, and prevent unnecessary water leakage at the water nozzle 15 of the connector 1 under normal conditions.

[0030] As a preferred technical solution of this embodiment, the protective cylinder 7 is provided with a through groove 8 inside. The through groove 8 includes a first vertical groove 801 and a second vertical groove 803. An arc-shaped groove 802 is provided between the first vertical groove 801 and the second vertical groove 803. A guide block 14 is fixedly installed on the side wall of the abutment cylinder 13. The guide block 14 is slidably connected to the through groove 8. When the abutment cylinder 13 and the protective cylinder 7 are installed, the guide block 14 slides down the first vertical groove 801, and then the abutment cylinder 13 is rotated. The guide block 14 slides inside the arc-shaped groove 802. When it slides to the top of the second vertical groove 803, the abutment cylinder 13 falls naturally and comes into contact with the glass rod 10 inside. At this time, the sealing component 11 above the abutment cylinder 13 is correspondingly blocked at the position of the water spray nozzle 15. When the glass rod 10 breaks, the abutment cylinder 13 continues to slide down inside the second vertical groove 803 through the guide block 14, thereby realizing the downward release of the sealing component.

[0031] As a preferred technical solution in this embodiment, filters 9 are provided on both sides of the protective cylinder 7. The filters 9 are mainly used to allow external hot air to flow into the interior of the protective cylinder 7, so that the glass rod 10 inside can respond quickly.

[0032] As a preferred technical solution in this embodiment, the side wall of the protective cylinder 7 is provided with a heat-conducting coating 16; the heat-conducting coating 16 can conduct external temperature and heat into the interior of the protective cylinder 7 as soon as a fire occurs, preventing the glass rod 10 from malfunctioning due to insufficient temperature.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
