Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing device technology, specifically a high-pressure fine water mist fire extinguishing device with a quickly switchable nozzle. Background Technology

[0002] In the field of fire protection, high-pressure fire extinguishing devices are widely used in various fire scenarios due to their high extinguishing efficiency. Currently, common high-pressure fire extinguishing devices are mainly divided into two types: direct-flow water type and atomized water type. Each type has its own functional focus to adapt to different fire extinguishing needs.

[0003] Common high-pressure fine water mist fire extinguishing devices typically employ fixed nozzle structures. Switching between nozzle modes requires specialized tools to disassemble and replace different components, a cumbersome and time-consuming process that fails to meet the need for rapid adjustment of fire extinguishing methods in fire environments. While some adjustable devices can achieve mode switching, they lack the ability to dynamically adjust spray parameters, thus failing to meet the operational requirements of fire extinguishing devices. Therefore, a high-pressure fine water mist fire extinguishing device with rapidly switchable nozzles is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-pressure fine water mist fire extinguishing device with a quickly switchable nozzle, thereby solving the technical problem that switching nozzle modes requires special tools to disassemble and replace different components due to the use of a fixed nozzle structure, which is cumbersome and time-consuming.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure fine water mist fire extinguishing device with rapidly switchable nozzles, comprising:

[0006] A water tank, wherein a pressure tank is installed on the outside of the water tank, and a pressure valve is installed at the bottom of the pressure tank;

[0007] A water pipe is connected to the outlet of a pressure valve and a water tank. A spray gun is installed at the outlet of the water pipe. A water nozzle is connected to the outlet of the spray gun. A hinge frame is movably connected to the outside of the water nozzle through a bearing.

[0008] A snap-fit ​​base is installed on the outside of the hinge frame. An adjusting plate is inserted inside the snap-fit ​​base. An impact-type atomizing head is installed on the inner side of the adjusting plate. A through groove is opened in the middle of the inside of the adjusting plate. Limiting slots are opened on both sides of the through groove inside the adjusting plate.

[0009] A transmission plate is inserted into both sides of the inside of the card holder. Limiting blocks are connected to the inside of the transmission plate, and springs are inserted into both sides of the inside of the limiting blocks.

[0010] Preferably, the water tank is connected to a mounting base on its outer side, and the mounting base is equipped with shoulder straps on both outer sides. The inner side of each shoulder strap is covered with a flexible pad to facilitate wearing the device on the back.

[0011] Preferably, the number of limiting slots is 10-20 sets, the interior of each limiting slot is connected to the interior of the through slot, and the size of the limiting plug is adapted to the limiting slot, which facilitates the insertion of the limiting plug into the interior of the limiting slot.

[0012] Preferably, a horizontal plate is connected to the middle of the inner cavity of the card seat, the outer ends of the springs are all connected to the corresponding positions on the outside of the horizontal plate, and the outer ends of the transmission plate are all equipped with protruding strips to facilitate pressing.

[0013] Preferably, a rubber buffer pad is fitted on the outside of the bearing at the connection between the hinge frame and the water nozzle. The surface of the rubber buffer pad has an arc-shaped groove, and wear-resistant particles are embedded in the inside of the arc-shaped groove, so that the hinge frame has resistance when swinging.

[0014] Preferably, the handle of the spray gun is equipped with a heat insulation sleeve, and the side of the water tank is equipped with a transparent observation window. A water level scale line is provided on one side of the transparent observation window to facilitate observation.

[0015] Compared with the prior art, this utility model provides a high-pressure fine water mist fire extinguishing device with quick nozzle switching, which has the following beneficial effects:

[0016] 1. This high-pressure fine water mist fire extinguishing device with quick-switchable nozzles can pressurize the water inside the tank through an added pressure tank and spray it out from the nozzle in the form of a straight water jet. When it is necessary to switch to fine water mist spray mode, the hinge bracket can be pushed to make it horizontal, so that the impact atomizing head is located directly in front of the water outlet nozzle. This allows the water sprayed from the water outlet nozzle to be transformed into fine water mist through the impact atomizing head. The nozzle switching can be completed by simply moving the hinge bracket without the need for additional tools, which improves the ease of use of the fire extinguishing device.

[0017] 2. This high-pressure fine water mist fire extinguishing device with quick-change nozzles allows for adjustment of the distance between the impact atomizing head and the water nozzle by pressing the transmission plate, which in turn moves the adjusting plate out of the limiting slot. This adjustment is achieved when operating in confined spaces by shortening the distance between the impact atomizing head and the water nozzle to enhance the water flow impact and ensure that the droplets penetrate obstacles. In open areas, increasing the distance optimizes the droplet distribution density and prevents premature evaporation due to excessively dense droplets, thus improving the practicality of the mist fire extinguishing device.

Detailed Implementation

[0025] 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.

[0026] This utility model provides a technical solution: a high-pressure fine water mist fire extinguishing device with a quickly switchable nozzle, comprising a water tank 1, a pressure tank 2, a mounting base 3, a pressure valve 4, a water pipe 5, a spray gun 6, a shoulder strap 7, a water nozzle 8, a hinge frame 9, a snap-fit ​​base 10, an adjusting plate 11, an impact atomizing head 12, a through groove 13, a limiting slot 14, a transmission plate 15, a horizontal plate 16, a limiting block 17, a spring 18, and a protruding strip 19.

[0027] Please see Figure 1 The water tank 1 is equipped with a pressure tank 2 on its outside. The pressure tank 2 is equipped with a pressure valve 4 at its bottom. The water tank 1 is connected to a mounting base 3 on its outer side. Both sides of the mounting base 3 are equipped with shoulder straps 7, and the inner side of the shoulder straps 7 is covered with a flexible pad.

[0028] Water pipe 5 connects to the outlet of pressure valve 4 and water tank 1. A spray gun 6 is installed at the outlet of water pipe 5. Please refer to [link / reference]. Figure 2The outlet of spray gun 6 is connected to a water nozzle 8. Please refer to [link / reference]. Figure 3 The outside of the water nozzle 8 is movably connected to the hinge frame 9 via a bearing;

[0029] The snap-fit ​​connector 10 is mounted on the outside of the hinge frame 9. Please refer to [link / reference]. Figure 4 Each card holder 10 has an adjustment plate 11 inserted inside. An impact-type atomizing head 12 is installed on the inner side of the adjustment plate 11. A through groove 13 is opened in the middle of the inside of the adjustment plate 11. Limiting slots 14 are opened on both sides of the through groove 13 inside the adjustment plate 11.

[0030] The added pressure tank 2 can pressurize the water inside the water tank 1 and spray it out from the spray gun 6 in the form of a straight water jet. When it is necessary to switch to the fine water mist spray mode, the hinge frame 9 can be pushed to make it horizontal, so that the impact atomizing head 12 is located in front of the water outlet nozzle 8. This allows the water sprayed from the water outlet nozzle 8 to be turned into a fine water mist by the impact atomizing head 12. The nozzle switching can be completed by simply moving the hinge frame 9 without the need for additional tools, thus improving the ease of use of the fire extinguishing device.

[0031] Please see Figure 5 and Figure 6 The transmission plate 15 is inserted into both sides of the inside of the card holder 10. The inner side of the transmission plate 15 is connected to the limit block 17, and the inner sides of the limit block 17 are each inserted with a spring 18.

[0032] The number of limiting slots 14 is 10-20 sets. The inside of each limiting slot 14 is connected to the inside of the through slot 13. The size of the limiting block 17 is adapted to the limiting slot 14. A horizontal plate 16 is connected to the middle of the inner cavity of the card seat 10. The outer ends of the springs 18 are connected to the corresponding positions on the outside of the horizontal plate 16. The outer ends of the transmission plate 15 are equipped with protrusions 19.

[0033] By pressing the transmission plate 15, the limiting insert 17 is disengaged from the limiting slot 14, thereby allowing the adjusting insert 11 to be pulled out. This allows the distance between the impact atomizing head 12 and the water nozzle 8 to be adjusted. In narrow spaces, the impact atomizing head 12 and the water nozzle 8 can be shortened to enhance the water flow impact force and ensure that the droplets penetrate obstacles. In open areas, the distance can be increased to optimize the droplet distribution density and prevent premature evaporation due to excessively dense droplets, thus improving the practicality of the fog fire extinguishing device.

[0034] A rubber buffer pad is fitted on the outside of the bearing at the connection between the hinge frame 9 and the water nozzle 8. The surface of the rubber buffer pad has an arc-shaped groove, and wear-resistant particles are embedded in the inside of the arc-shaped groove. A heat insulation sleeve is installed at the handle of the spray gun 6. A transparent observation window is installed on the side of the water tank 1, and a water level scale line is provided on one side of the transparent observation window.

[0035] This design utilizes a pressure tank 2 to pressurize the water inside the water tank 1, allowing it to be sprayed out of the spray gun 6 as a straight water jet. When switching to a fine water mist spray mode, the hinge frame 9 can be pushed to a horizontal position, positioning the impact atomizing head 12 directly in front of the water outlet nozzle 8. This allows the water sprayed from the water outlet nozzle 8 to be atomized into a fine water mist by the impact atomizing head 12. Sprayer switching can be completed simply by moving the hinge frame 9 without the need for additional tools, significantly improving the ease of use of the fire extinguishing device. Simultaneously, by pressing the transmission plate 15, the limiting insert 17 is disengaged from the limiting slot 14, thereby allowing the adjusting insert 11 to be pulled out. This allows the distance between the impact atomizing head 12 and the water nozzle 8 to be adjusted. In narrow spaces, the impact atomizing head 12 and the water nozzle 8 can be shortened to enhance the water flow impact force and ensure that the droplets penetrate obstacles. In open areas, the distance can be increased to optimize the droplet distribution density and prevent premature evaporation due to excessively dense droplets, thus improving the practicality of the fog extinguishing device.
