Description

Technical Field

[0001] The present invention belongs to the technical field of fire sprinklers, and in particular relates to a fire sprinkler with a drilling intrusion function and a fire extinguishing method. The sprinkler penetrates the external surface by autonomous drilling and extends to the internal space of the fire source, thereby realizing directional fire extinguishing in concealed spaces (such as mezzanines and pipe wells), puncture fire extinguishing in closed containers (such as lithium battery packs and chemical storage tanks), and emergency treatment of special fire situations that traditional sprinkler systems cannot cover. Background Art

[0002] The sprinklers currently used in fire protection systems can only extinguish open flames outside the nozzles and are ineffective against hidden fire sources such as those in wall cavities and inside equipment. Traditional sprinkler technology also faces the problem of explosion-proof casings blocking the penetration of fire extinguishing agents, making it impossible to continuously suppress internal re-ignition. Some improvement solutions rely on drilling holes first and then inserting sprinklers deeper into the interior to extinguish the fire, which delays fire extinguishing. Summary of the Invention

[0003] In order to overcome the problems existing in the prior art, the present invention provides a fire sprinkler with a drilling intrusion function, which has the characteristics of puncturing and extinguishing fires in hidden spaces and closed containers. It is used in conjunction with an electric drill and a water injector to achieve drilling and spraying fire extinguishing agent to extinguish fires at the same time.

[0004] The fire sprinkler comprises a sprinkler body and a drill head component. A water outlet is provided in the middle of the sprinkler body, and the water outlets are distributed at equal intervals around the sprinkler body.

[0005] Furthermore, the lower part of the nozzle body is a water injector joint, and the water injector joint is provided with a water outlet hole and a water injector mounting hole, and the water outlet holes are distributed at equal intervals around the water injector joint.

[0006] Furthermore, a nozzle is provided on the water outlet, and the water outlet is connected to the nozzle via threads.

[0007] Furthermore, the inner wall of the water injector mounting hole is provided with an internal thread for connecting the water injector.

[0008] Furthermore, a drill bit connecting hole is provided on the upper portion of the nozzle body, and an internal thread is provided on the inner wall of the drill bit connecting hole for connecting the drill bit component.

[0009] Furthermore, the drill bit component is a multi-blade step drill, the drill bit is provided with a chip groove, the bottom of the step drill is provided with a drill bit connecting column, the outer wall of the drill bit connecting column is provided with a thread, and can be rotatably fixed in the drill bit connecting hole.

[0010] The present invention also provides a fire extinguishing method using the fire sprinkler, comprising the following steps: (1) Equipment assembly steps: a. Fix the drill bit component to the drill bit connection hole of the nozzle body through threaded connection; b. Fix the water injector into the water injector mounting hole of the nozzle body through threaded connection; c. Install the water injector on the chuck of the electric drill; (2) Positioning steps: a. Determine the location of the fire source and the surface of the obstacle that needs to be drilled; b. Align the drill tip of the fire sprinkler head with the predetermined drilling position; (3) Drilling fire extinguishing synchronization steps: a. Start the electric drill and make the drill bit start rotating and drilling; b. Simultaneously start the water injector to allow the fire extinguishing agent to pass through the central channel of the nozzle body; c. Fire extinguishing agent is sprayed from the water outlet hole, and fire extinguishing operation begins during the drilling process; (4) In-depth fire extinguishing steps: a. After the drill bit penetrates the obstacle, continue to advance the nozzle body; b. Extend the nozzle to the core area of the fire source and spray the fire extinguishing agent directly to the fire source; (5) Fire extinguishing completion steps: a. After confirming that the fire source is completely extinguished, stop the water supply from the water injector; b. Turn off the electric drill and exit the fire sprinkler.

[0011] Furthermore, in the drilling and fire extinguishing synchronization step, the electric drill speed and propulsion pressure can be adjusted according to the material of the obstacle, and the fire extinguishing agent injection pressure can be adjusted at the same time to ensure the best drilling and fire extinguishing effects.

[0012] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention provides a drill bit component on the upper part of the nozzle body, which can realize active intrusion fire extinguishing. After the drill bit penetrates the obstacle, the nozzle extends to the core area of the fire source to spray the fire extinguishing agent; (2) The present invention can realize the synchronous operation of drilling and spraying. The fire extinguishing agent is released through the central channel of the nozzle during the drilling process, eliminating the steps of drilling first and then spraying the fire extinguishing agent, thus seizing the opportunity to extinguish the fire; (3) The fire extinguishing method provided by the present invention is simple to operate and can complete the drilling and fire extinguishing operations in an integrated manner, thereby significantly improving the fire extinguishing efficiency. It is particularly suitable for extinguishing fires in enclosed spaces and concealed fire sources. BRIEF DESCRIPTION OF THE DRAWINGS
