Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing equipment technology, and more specifically to a portable fine mist fire extinguishing device. Background Technology

[0002] Fine mist fire extinguishing devices, especially high-pressure fine water mist, are now widely used. They are highly efficient at extinguishing fires and preventing the spread of fires. They also have a significant washing and scouring effect on smoke and dust, which can improve visibility at fire scenes and facilitate the evacuation of personnel and fire fighting and rescue.

[0003] Currently, when using portable fine mist fire extinguishing devices, their structure mainly utilizes branch pipes to support the fine mist nozzles, transport water through the branch pipes, and then spray the water from the fine mist nozzles towards the fire source to extinguish the fire. In order to adapt to fire sources in different locations, the angle of the fine mist spray can be adjusted by changing the angle of the branch pipes. However, the angle between the fine mist nozzles and the branch pipes is generally fixed. If there are obstacles near the fire source, it is difficult to avoid the obstacles by simply adjusting the angle of the branch pipes, which affects the water spraying towards the fire source. Therefore, it has the defect of insufficient applicability.

[0004] In view of this, the present invention proposes a portable fine mist fire extinguishing device to solve this problem. Utility Model Content

During the use of the fine mist nozzle, a servo motor drives the horizontal lead screw to rotate, which in turn moves the moving block. The support rod supports the outer cylinder rod, allowing adjustment of the height of the fine mist nozzle. The extension and retraction of the electric push rod causes the inner cylinder rod to extend, further adjusting the height and distance of the fine mist nozzle.

Multiple fine mist nozzles increase the width of the mist spray, improving extinguishing effectiveness. A positioning component, using threaded set screws to engage with different toothed grooves, locks the core rod in place. The hydraulic rod's extension and retraction move the rack, which, through meshing with the gear disc, deflects the outer cylinder rod, adjusting the direction of the fine mist nozzles and further expanding the extinguishing angle. A rotary joint reduces the torsional effect of the outer cylinder rod's deflection on the spring telescopic tube, protecting it. Attached Figure Description
