Description

Technical Field

[0001] This utility model relates to the field of sprinkler technology, specifically a fire sprinkler head. Background Technology

[0002] Fire sprinkler heads are key components of automatic sprinkler systems, widely used in various buildings, warehouses, factories, and other locations. Their main function is to automatically activate upon sensing temperature changes during a fire, spraying water to control and extinguish the fire. Due to the importance of fire sprinkler heads in fire prevention and control, their reliability and stability are directly related to the safety of life and property. However, in cold regions or low-temperature winter environments, fire sprinkler heads are prone to freezing and failure. When the ambient temperature is below freezing, the water inside the sprinkler head may freeze, causing the sprinkler head to fail to open normally, or even to stop spraying water during a fire. This situation seriously affects the reliability of the fire protection system and increases the risk of fire.

[0003] Therefore, we have designed a fire sprinkler head to solve the above problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 In this embodiment: a fire sprinkler head is mainly used to prevent the sprinkler head from freezing in low temperature environment and to ensure that the fire protection system can operate normally in emergency situations. The fire sprinkler head includes a sprinkler head body 1, an insulation board 2, an electric heating wire 3, a temperature control switch 4, a battery compartment 5, a battery 6, a shell 7, a cover plate 8, a protrusion 9, an external threaded pipe 10, a plug 11, a bracket 12, a glass ball 13, and a sprinkler plate 14.

[0019] Please see Figure 1The nozzle body 1 has a water inlet at the top and a water outlet at the bottom. The water inlet is connected to the water supply pipe through an external threaded pipe 10 to ensure that the water source can smoothly enter the nozzle body 1. A plug 11 is installed on the water outlet to seal the water outlet when not in operation to prevent water leakage. A bracket 12 is installed at the bottom of the nozzle body 1. A glass ball 13 is placed between the bracket 12 and the plug 11. The glass ball 13 is hollow and filled with kerosene. When the ambient temperature rises to a certain value, the kerosene in the glass ball 13 expands, causing the glass ball 13 to break, thereby releasing the plug 11 and allowing water to spray out from the water outlet. A sprinkler plate 14 is installed at the bottom of the bracket 12 and is located directly below the water outlet of the nozzle body 1. The function of the sprinkler plate 14 is to evenly disperse the water flow to form a large-area sprinkler effect, thereby improving the fire extinguishing efficiency.

[0020] Please see Figures 1-3 The nozzle body 1 has an insulation plate 2 installed on its outer side, and an electric heating wire 3 embedded on its inner side. The main function of the insulation plate 2 is to provide insulation for the nozzle body 1 in low-temperature environments and prevent the nozzle from freezing. The insulation plate 2 is fitted with a housing 7, and a battery compartment 5 is installed inside the housing 7. The battery compartment 5 contains a removable and replaceable battery 6. The electric heating wire 3 is powered by the battery 6 and can heat the nozzle body 1 in low-temperature environments, thereby ensuring that the temperature of the nozzle body 1 is kept above the freezing point. A temperature control switch 4 is installed at the bottom of the nozzle body 1 to control the switching of the electric heating wire 3. When the ambient temperature is lower than the set value, the temperature control switch 4 automatically turns on the circuit and the electric heating wire 3 starts to heat. When the temperature rises above the set value, the temperature control switch 4 automatically turns off the circuit and stops heating. By setting the temperature control switch 4 to control the switching of the electric heating wire 3, energy is saved and overheating is effectively prevented.

[0021] Please see Figure 3 and Figure 4 The front of the housing 7 has an opening, and the inside of the opening has a slot. A removable cover 8 is installed in the slot. By pulling the cover 8 out of the slot, the battery compartment 5 and the battery 6 inside the housing 7 can be exposed, making it convenient for the user to replace the battery later. The front of the cover 8 has a protrusion 9, which makes it easy for the user to open and close the cover 8.

[0022] Working principle: Under normal circumstances, the water outlet of the nozzle body 1 is sealed by the plug 11, and water will not flow out. When the ambient temperature rises to the expansion temperature of kerosene, the glass ball 13 breaks, the plug 11 is released, and water sprays out from the water outlet and is evenly sprayed onto the fire source through the water spray plate 14.

[0023] In low-temperature environments, when the temperature control switch 4 detects that the temperature is lower than the set value, it automatically connects the circuit of the heating wire 3, and the heating wire 3 starts to heat the nozzle body 1 to prevent the nozzle body 1 from freezing. When the temperature rises above the set value, the temperature control switch 4 automatically disconnects the circuit and stops heating.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
