Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a high-pressure fine water mist fire extinguishing device. Background Art

[0002] Fire extinguishing devices have a variety of fire extinguishing methods. For example, foam fire extinguishing has the advantages of high foaming multiples and can quickly fill the fire space in a short time. It is mainly suitable for extinguishing fires of various solid combustibles such as oil, wood, fiber, rubber, etc., but the fire extinguishing effect on underground projects, ships, valuable instruments and equipment and items is poor. High-pressure fine water mist can extinguish fires quickly and has the characteristics of no pollution, little damage on the site, good fire extinguishing effect, low water consumption, and good electrical insulation.

[0003] The nozzles in traditional handheld fire extinguishing devices have a single function, which is only equipped with a single fine water mist spraying function or a foam spraying function. The prior art mentions the use of nozzle switching, but it basically controls different valve ports inside the pipeline to use the corresponding nozzles for fire extinguishing. The production and processing process of the built-in structure is technically cumbersome, and the subsequent use, maintenance and replacement are also relatively difficult.

DETAILED DESCRIPTION

[0021] The utility model is further described in detail below through the drawings and embodiments.

[0022] like Figure 1-2 As shown: a high-pressure fine water mist fire extinguishing device, including a spray gun connector 1, a water outlet pipe 2, an adjustment component, a rotating seat 4, a connecting seat 5, and a nozzle 6. The spray gun connector 1 is connected to an external water pipe and connected to the water outlet pipe 2. The far end of the water outlet pipe 2 is rotatably connected to the rotating seat 4. The connecting seat 5 is tightly in contact with the outer side of the rotating seat 4 and fixed to the water outlet pipe 2. The nozzle 6 is installed on the connecting seat 5, which is provided with multiple nozzles with different functions and used for different modes (such as short-range fine water mist scattering fire extinguishing, long-range jet fine water mist fire extinguishing, foam fire extinguishing, etc.). An adjustment component is installed on the water outlet pipe 2, wherein the rotating seat 4 is only connected to one of the nozzles 6, and the rotating seat 4 is driven by the adjustment component to rotate and switch to connect to any nozzle 6.

[0023] The switchable structures of the nozzles 6 are all external, so the operation is simpler and the installation and maintenance are easy.

[0024] The outer wall of the connecting seat 5 is connected with a long rod 3 , which extends to the water outlet pipe 2 and is connected to the outer wall of the water outlet pipe 2 , so that the connecting seat 5 can be fixed and almost avoid being affected by the movement of the rotating seat 4 .

[0025] like Figure 3-4 As shown: the adjustment component includes a rotating gear ring 7, which is pivotally connected to the outer wall of the water outlet pipe 2. The rotating gear ring 7 is longitudinally connected to a pillar 8 with two ends passing through. A spring 9 is axially connected inside the pillar 8. A pull handle 10 is connected to the upper end of the spring 9. The pull handle 10 is located inside the pillar 8 and is axially connected to an extension rod 11. The other end of the extension rod 11 is connected to a clamping column 12. A through hole 13 is opened at the rotating gear ring 7 corresponding to the pillar 8. Under normal conditions, the clamping column 12 is placed in the through hole 13 under the action of the spring 9. It should be noted that the wall of the water outlet pipe 2 is provided with through openings equal to the number of nozzles 6, and the positions of the through openings correspond to the positions of the nozzles 6.

[0026] The outer wall of the pillar 8 is connected with a support rod 13, and the distal end of the support rod 13 is connected to the outer wall of the rotating seat 4, so that the two rotate in unison. After the rotating gear ring 7 is switched, the clamping column 12 passes through the through hole 13 and is inserted into the through port, so that the rotating gear ring 7 is limited to the water outlet pipe 2. When it is necessary to switch to a different nozzle 6 mode, the handle 10 can be pulled outward to separate the pillar 8 from the through port.

[0027] When rotating and switching different modes of the nozzle 6, the rotation angle needs to be controlled relatively accurately, and the process of rotating the opening of the clamping column 12 requires a certain trial and error time, which is relatively slow. Figure 2 As shown, magnets can be arranged at the periphery of the connecting port 14 opened on the rotating seat 4, and magnets with different magnetic properties are respectively arranged at the nozzle 6 installed on the connecting seat 5. After the connecting port 14 is aligned with the corresponding nozzle 6, the two magnets overlap, and then there is a greater suction force when it is rotated to the desired position to facilitate rotation adjustment.

[0028] The above-mentioned embodiments are for inspiration. Through the above-mentioned description, relevant staff can make various changes and modifications without departing from the scope of the invention. The technical scope of this new type of use is not limited to the content in the specification, and its protection scope must be determined according to the scope of the claims.
