Description

Technical Field

[0001] The utility model relates to the field of fire-fighting equipment, in particular to a sprinkler for fire emergency rescue. Background Art

[0002] A sprinkler for fire emergency rescue is a fire-fighting and extinguishing device and a widely used fixed fire-fighting facility. It has the characteristics of low price and high fire-extinguishing efficiency. The sprinkler for fire emergency rescue is generally installed on the wall or ceiling and connected to a water network pipeline filled with pressure, or individual sprinklers are installed along the pipeline to protect the area below them. In case of a fire, it can automatically release water or other fire extinguishing agents to control the fire or extinguish the fire source, or at least control the heat and limit the generation of toxic smoke;

[0003] For the commonly used sprinkler for fire emergency rescue, by setting a sprinkler head, a heat-sensitive glass bulb, a side support frame, a water-blocking block, a sprinkler, etc., kerosene, ether and other solutions are stored in the heat-sensitive glass bulb. The action temperatures of various colors are: red 68°C, yellow 79°C, green 93°C, blue 141°C. The top of the sprinkler head is threaded and is threadedly connected inside the water pipe. In case of a fire, when the heat-sensitive glass bulb in the sprinkler head is exposed to high temperature, the liquid inside will start to expand. When the set expansion temperature is exceeded, the liquid will squeeze the glass bulb and break it. At this time, the water-blocking block will slide down from the inside of the sprinkler head, and the water in the water pipe will flow out. The ejected water will fall into the sprinkler and splash to the protected area below;

[0004] For the commonly used sprinkler for fire emergency rescue, when a large number of installations are required, it is extremely inconvenient. It is necessary to manually rotate the sprinkler into the water pipe, which wastes installation time and reduces the installation efficiency. Therefore, a sprinkler for fire emergency rescue is proposed to solve the above problems. Content of the Utility Model

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figure 2 and Figure 3 and Figure 4, an embodiment of the utility model provides a fire emergency sprinkler head, including a sprinkler head 1. A support frame 2 is fixedly connected to the bottom of the sprinkler head 1 to prevent the thermal glass tube 3 from falling off. A thermal glass tube 3 is fixedly connected inside the support frame 2. A plug block 4 is arranged at the top of the thermal glass tube 3. When the thermal glass tube 3 is subjected to high temperature, the thermal liquid inside expands to burst the thermal glass tube 3, causing the plug block 4 to slide off from the inside of the sprinkler head 1 due to excessive water pressure, and the sprinkler head 1 sprays out water. A telescopic hose 5 is fixedly connected to the top of the sprinkler head 1, enabling the sprinkler head 1 to move and facilitating the adjustment of the installation angle. A connecting pipe 6 is fixedly connected to the top of the telescopic hose 5. A water pipe 7 is slidably connected inside the connecting pipe 6, facilitating the connection between the connecting pipe 6 and the water pipe 7. Two mounting blocks 8 are fixedly connected to the outer periphery of the connecting pipe 6. An installation shell 9, the top of the mounting block 8 is fixedly connected to the shell 9, and other components are installed inside the shell 9. A bolt 10 is slidably connected inside the shell 9. A sliding block 11 is fixedly connected to the outer periphery of the bolt 10. A spring 12 is fixedly connected to the side of the sliding block 11 away from the connecting pipe 6. One end of the spring 12 away from the sliding block 11 is fixedly connected to the inner wall of the shell 9. Pull the pull column 16, the pull column 16 drives the bolt 10, the bolt 10 moves to drive the sliding block 11, and the sliding block 11 compresses the spring 12 when moving. When the spring 12 is compressed, it generates an elastic force. Release the pull column 16, and the elastic force can push the sliding block 11, and the sliding block 11 drives the bolt 10 to reset. An adjusting component is arranged outside the sprinkler head 1, which can adjust the installation angle of the sprinkler head 1. The bolt 10 passes through the connecting pipe 6 and is inserted into the inner wall of the water pipe 7 to fix the water pipe 7 and prevent the water pipe 7 from slipping out. The outer side of the sliding block 11 is slidably connected to the inner wall of the shell 9, and the sliding block 11 can compress the spring 12 or be pushed by the spring 12 when moving. The outer side of the plug block 4 is slidably connected inside the sprinkler head 1, enabling the plug block 4 to fall off and facilitating the spraying of water. One end of the bolt 10 away from the connecting pipe 6 is fixedly connected to a pull column 16.

[0033] Referring to Figure 1 and Figure 2 , the adjusting component includes a mounting rod 13. The outer side of the bottom of the mounting rod 13 is fixedly connected to the outer side of one of the mounting blocks 8, and other components are installed. A threaded rod 14 is threadedly connected inside the bottom end of the mounting rod 13. A connecting block 15 is rotatably connected to the outer periphery of the threaded rod 14. The connecting block 15 is hinged to the sprinkler head 1. When the threaded rod 14 rotates, it drives the connecting block 15, the connecting block 15 drives the sprinkler head 1, and the sprinkler head 1 drives the telescopic hose 5 to adjust the angle of the sprinkler head 1. One end of the threaded rod 14 away from the connecting block 15 is fixedly connected to a turning head 17, which facilitates the rotation of the threaded rod 14.

[0034] Working principle: During installation, pull the pull rod 16. The pull rod 16 drives the plug 10 to be withdrawn from the inside of the connecting pipe 6. The movement of the plug 10 drives the sliding block 11, and the sliding block 11 compresses the spring 12, causing the spring 12 to generate elastic force. Slide the water pipe 7 into the inside of the connecting pipe 6. Release the pull rod 16. The elastic force generated by the spring 12 pushes the sliding block 11, and the sliding block 11 drives the plug 10 to automatically insert into the inner wall of the water pipe 7, preventing the water pipe 7 from falling off and slipping out. When adjusting the installation angle, rotate the rotating head 17. The rotating head 17 drives the threaded rod 14 to rotate. The threaded rod 14 drives the connecting block 15, and the connecting block 15 drives the nozzle 1. The nozzle 1 drives the telescopic hose 5. The forward and reverse rotations of the threaded rod 14 can adjust the installation angle of the nozzle 1 to more accurately protect the area to be protected. After adjusting to the appropriate angle, stop rotating the rotating head 17. When the heat-sensitive glass tube 3 is exposed to high temperature, the heat-sensitive liquid inside expands due to heat and bursts the heat-sensitive glass tube 3. The fragments of the heat-sensitive glass tube 3 fall off, causing the plug block 4 to lose support. The water pressure inside the nozzle 1 squeezes the plug block 4 out of the nozzle 1, and the water source sprays out from the inside of the nozzle 1.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
