Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a sprinkler head protection device and a sprinkler head with the same. Background Art

[0002] High-pressure water mist nozzles use high pressure to break water into tiny droplets or mist. These droplets cover a large area in the air, effectively reducing the temperature at the fire scene and controlling the fire. In modern industry and construction, high-pressure water mist nozzles are widely used in various firefighting systems due to their advantages such as efficient cooling, rapid fire extinguishing, and minimal water staining.

[0003] Existing high-pressure fine water mist nozzle fixing methods usually adopt rigid connection, such as threaded connection, pipe clamp connection and the like.

[0004] The above-mentioned rigid connection method lacks effective buffering and vibration reduction measures. When the nozzle pipe is impacted by external force, it is easy to be scratched and worn, and may even cause damage to the nozzle, affecting the fire extinguishing effect. In addition, the rigidly connected nozzle is prone to fatigue cracks due to stress concentration under vibration and impact conditions, further shortening the service life of the nozzle.

[0040] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] like Figure 1 The figure shows a specific embodiment of the nozzle protection device provided in this embodiment, which includes: an assembly frame 1, a buffer surround sleeve 2, and a connector 3. The buffer surround sleeve 2 is placed inside the assembly frame 1, and is used to be mounted on the outer wall of the nozzle pipe 6; the connector 3 has two symmetrically distributed on both sides of the buffer surround sleeve 2, one end of the connector 3 is connected to the inner side of the assembly frame 1, and the other end of the connector 3 is connected to the outer side of the buffer surround sleeve 2, and the connector 3 is rotatably connected to the assembly frame 1 and / or the buffer surround sleeve 2.

[0042] like Figure 3 As shown, in the sprinkler protection device provided in this embodiment, the assembly bracket 1 is used to install and secure the sprinkler protection device as a whole, and the buffer surround 2 is used to secure the sprinkler pipe 6. The assembly bracket 1 and the buffer surround 2 are rotatably connected via two symmetrically distributed connectors 3. This arrangement can buffer the sprinkler head from vibrations caused by external forces or internal high-pressure water flow, thereby improving the durability and flexibility of the sprinkler head and extending its service life.

[0043] like Figure 1 As shown, in the sprinkler head protection device provided in this embodiment, the connecting member 3 is a bearing support rod, one end of which is connected to the assembly frame via a rotating bearing 4. This arrangement enables the buffer surround 2 to rotate accordingly based on the impact experienced by the sprinkler head. Of course, the above description is not restrictive; in some alternative embodiments, the connecting member 3 can also be connected to the assembly frame via a roller ball bearing.

[0044] like Figure 1 As shown, in the nozzle protection device provided in this embodiment, the other end of the connecting member 3 is fixedly connected to the buffer surrounding sleeve 2. Specifically, the connecting member 3 and the buffer surrounding sleeve 2 are fixedly connected by glue. Of course, the above description is not restrictive. In some alternative embodiments, the connecting member 3 and the buffer surrounding sleeve 2 can also be connected by other means, such as mechanical connection.

[0045] like Figure 2 As shown, in the nozzle protection device provided in this embodiment, a sponge pad 5 is disposed inside the assembly frame 1. This arrangement can reduce wear caused by the contact between the rotating buffer sleeve 2 and the assembly frame 1, further effectively buffering and reducing vibration. Of course, the above description is not restrictive. In some alternative embodiments, the sponge pad 5 can also be made of other materials, such as rubber pads.

[0046] like Figure 2 As shown, in the nozzle protection device provided in this embodiment, the sponge pads 5 are symmetrically arranged, with the two sponge pads 5 being respectively positioned between the two connecting members 3. This arrangement effectively cushions the vibration of the nozzle in multiple directions. Of course, the above description is not restrictive. In some alternative embodiments, the sponge pads 5 can also be configured as a ring surrounding the buffer sleeve 2.

[0047] Such as Figure 1As shown, in the nozzle protection device provided in this embodiment, the buffer surrounding sleeve 2 is a rubber sleeve. Because rubber has high elasticity, high tensile strength, and good durability, it can improve the applicability and durability of the nozzle protection device. Of course, the above description is not restrictive. In some alternative embodiments, the buffer surrounding sleeve 2 can also be made of other materials, such as silicone.

[0048] In addition, if Figure 3 As shown, this embodiment further provides a nozzle, comprising: a nozzle pipe 6, a nozzle body 7 and a nozzle protection device. The buffer surrounding sleeve 2 of the nozzle protection device is used to be sleeved on the outer wall of the nozzle pipe 6, and the nozzle body 7 is placed at the end of the nozzle pipe 6.

[0049] like Figure 3 As shown, in the nozzle provided in this embodiment, a plurality of nozzle protection devices are sequentially connected to the nozzle pipe 6 to further enhance the overall cushioning and vibration reduction effects. Of course, the above description is not restrictive. In some alternative embodiments, the nozzle protection device may have more or only one.

[0050] like Figure 4 As shown, in the nozzle protection device provided in this embodiment, a sealing ring 8 is provided at the connection between the nozzle body 7 and the nozzle pipe 6, which prevents water leakage in the pipe and improves the reliability of the nozzle. Of course, the above description is not restrictive. In some alternative embodiments, the sealing connection between the nozzle body 7 and the nozzle pipe 6 can also be achieved by other means, such as adhesive sealing.

[0051] like Figure 4 As shown, in the nozzle provided in this embodiment, a filter screen 9 is provided at one end of the nozzle pipe 6. Specifically, the filter screen 9 is a circular fine filter screen. This configuration reduces the amount of impurities entering the nozzle, prevents nozzle clogging, and increases the service life of the nozzle. Of course, the above description is not restrictive. In some alternative embodiments, the filter screen 9 can also be configured as a multi-layer filter structure.

[0052] Working principle:

[0053] The nozzle protection device is fixed to the desired position through the assembly frame 1, and the nozzle pipe 6 is fixed by the buffer surround sleeve 2. The assembly frame 1 and the buffer surround sleeve 2 are directly rotatably connected through the cooperation of the bearing support rod and the rotating bearing 4. When the nozzle is impacted by external force or internal high-pressure water flow, the buffer surround sleeve 2 rotates accordingly according to the impact on the nozzle, and the impact is reduced by rotation. At the same time, the sponge pad 5 further buffers and reduces the collision and wear generated by the buffer surround sleeve 2 and the assembly frame 1 during the rotation process, thereby avoiding wear and damage to the nozzle due to impact, thereby improving the stability of the nozzle and increasing the service life of the nozzle.

[0054] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
