The terms "install," "connect," "join," and "fix" should be interpreted broadly. For example, "connect" can be a fixed connection, a detachable connection, or an integral connection; "join" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0051] like Figures 1-4 As shown, this embodiment provides a fire-fighting sprinkler device 100 for building fire protection, including a first nozzle 20 and a connecting pipe 10 disposed on the first nozzle 20, which is used to connect to a pipeline system;

[0052] The first nozzle 20 is connected to the second nozzle 30 via a connecting pipe 306;

[0053] The second nozzle 30 includes a mounting base 303, in which a tension spring 304 is provided. The first end of the tension spring, which is away from the tension spring seat, is mounted on the sealing device 50. The sealing device 50 is fixedly mounted on the mounting base 303, and one end of the sealing device 50 extends out of the mounting base 303 and is located outside the mounting base.

[0054] The tail end of the tension spring is disposed on the tension spring seat and is integrally disposed with the tension spring seat.

[0055] Furthermore, a valve stem 305 is provided in the connecting pipe 306 that is integrally formed with and connected to the mounting base 303, and the valve stem is mounted on the spring seat;

[0056] The valve stem 305 end away from the tension spring is connected to the sealing element 308 by a fixed connection (e.g., welding, adhesive, etc.). When in a non-working state (unopened state), the sealing element 308 abuts against the inner wall of the connecting pipe of the first nozzle 20 to prevent water from entering the chamber 202 through the connecting pipe of the first nozzle. The sealing element 308 is made of elastic material so that the outer wall of the sealing element can fit tightly against the inner wall of the connecting pipe.

[0057] Furthermore, the sealing device is made of a fusible material. When it is in a low-temperature state, the sealing device is in a solid state. When it is in a high-temperature state (obtained through multiple experiments, the melting temperature is generally 68°C), it will melt and become liquid.

[0058] Furthermore, the outer diameter of the seal is smaller than the inner diameter of the connecting pipe.

[0059] Furthermore, the chamber 202 is provided with multiple sets of spray holes 201.

[0060] In this embodiment, it should be noted that when the device is not in operation, the pressure exerted by the compression spring 304 on the seal is greater than the pressure exerted by the water on the seal. When a fire occurs, the temperature rises, and the sealing device is melted by the high temperature, releasing the pressure exerted by the compression spring on the seal. Under the impact of the water pressure, the seal is pushed into the connecting pipe 306 by the water pressure. At this time, the water flows into the chamber 202 and the connecting pipe 306, and the water is sprayed out through the nozzle provided on the chamber 202.

[0061] Because existing fire sprinkler systems have nozzles that are closed when not in use, prolonged periods of disuse can lead to blockages from dust, grease, corrosion, or other substances, resulting in areas without water coverage and creating blind spots. To resolve these technical issues, please refer to [link to relevant documentation / reference]. Figure 1-4 As shown, the water outlet of the mounting base 303 is connected to the guide pipe 302, and the water outlet of the guide pipe 302 is connected to the spray plate 301. The spray plate has multiple sets of spray holes; and the spray plate 301 is made of stainless steel and is arranged in an umbrella shape.

[0062] In practical applications, when a fire occurs, the temperature rises, melting the sealing device and releasing the pressure exerted on the seal by the compression spring. Under the impact of water pressure, the seal is pushed into the connecting pipe 306. At this time, water flows into the chamber 202 and the connecting pipe 306. Part of the water flows out through the nozzles set on the chamber 202, while the other part of the water is transported to the guide pipe 302 through the connecting pipe 306 and sprayed out through the spray holes of the spray plate. By using the first and second nozzles in combination, the water coverage area can be increased, preventing the occurrence of blind spots.

[0063] To improve the stability of fire sprinkler systems, please refer to [link / reference]. Figure 2 As shown, a protective mechanism 40 for improving stability is installed on the connecting pipe 306 of the fire extinguishing sprinkler device 100; the protective mechanism 40 includes a slide rail 401, which is installed on the wall or building to be installed by a fastening nut; a sliding clamping plate 404 is provided inside the slide rail 401, which can slide inside the slide rail, and the slide rail 401 also includes a bent end 402, and the groove 403 matches the bent end 402;

[0064] The sliding clamping plate 404 is arc-shaped and is used to clamp the connecting pipe 306. An ear plate 405 is provided on the sliding clamping plate 404 away from the slide rail 401. The ear plate 405 is threadedly connected to a fastening screw in the threaded hole and is fixedly connected by a fastening nut.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not restrictive. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
