Description

Technical Field

[0001] This utility model relates to the field of perfluorohexanone fire extinguishing technology, specifically a novel water mist perfluorohexanone fire extinguishing device that is easy to replace. Background Technology

[0002] Perfluorohexanone (FK-5-1-12) is a special fire extinguishing agent, belonging to the fluorinated compound fire extinguishing agent class. Its application in firefighting is typically for extinguishing liquid fires, electronic equipment fires, and other similar high-risk fire situations.

[0003] Its working principle is as follows: Perfluorohexanone fire extinguishing agent works by cooling, inhibiting chemical chain reactions, and suppressing the oxygen supply. When sprayed onto a fire source, it can rapidly evaporate and absorb heat, lowering the fire source temperature. Furthermore, the fluorine atoms in the perfluorohexanone molecule can react with free radicals, inhibiting the spread of flames. Most importantly, perfluorohexanone can reduce the oxygen supply around the fire source, suffocating it.

[0004] Existing perfluorohexanone (PFH) fire extinguishing devices are mostly inconvenient to transport and difficult to replace quickly, thus limiting their practicality. To address these issues, a novel water mist-type PPH fire extinguishing device that is easy to replace is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a novel water mist perfluorohexanone fire extinguishing device that is easy to replace, which solves the problem that most existing perfluorohexanone fire extinguishing devices in the background art are inconvenient to transport and difficult to replace quickly, resulting in poor practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel water mist perfluorohexanone fire extinguishing device that is easy to replace, comprising a movable base, two sliding grooves on the top of the movable base, a buffer assembly in the sliding groove, a placement seat connected to the top of the buffer assembly, an installation groove on the top of the placement seat, a bidirectional threaded rod passing through and rotatably connected in the installation groove, a handwheel fixedly connected to the rear end of the bidirectional threaded rod, movable plates threaded to both sides of the outer ring of the bidirectional threaded rod, clamps fixedly connected to the top of the two movable plates, a U-shaped frame on the outside of the clamps, multiple springs fixedly connected to the inside of the U-shaped frame, and the other end of the springs fixedly connected to the clamps, two grooves on adjacent sides of the two U-shaped frames, a perfluorohexanone bottle in each of the two grooves, a connecting head fixedly connected to the top of the perfluorohexanone bottle, a spray pipe fixedly connected to the outside of the connecting head, a nozzle fixedly connected to the end of the spray pipe, and casters fixedly connected to the four corners of the bottom of the movable base.

[0007] By adopting the above technical solution, the two movable plates and the U-shaped frame can be driven to move relative to each other or in opposite directions by the bidirectional threaded rod, which facilitates the replacement and installation of the fire extinguishing device.

[0008] As a further description of the above technical solution: the buffer assembly includes sliders, both sliders are disposed in the slide groove, and a support rod is rotatably connected to the adjacent side of the two sliders. The adjacent end of the two support rods is rotatably connected to the bottom of the placement seat. A spring damper is disposed on the opposite side of the two sliders, and the spring damper is disposed in the slide groove.

[0009] By adopting the above technical solution, when encountering bumpy roads or uneven ground during transportation, the spring damper of the buffer component can absorb vibration energy, preventing the vibration from being directly transmitted to the perfluorohexanone bottle above. At the same time, the support rod rotatably connected to the bottom of the slider and the placement seat can function when subjected to horizontal force, maintaining the balance and stability of the placement seat through adaptive adjustment of its own angle, ensuring the safety of the bottle.

[0010] As a further description of the above technical solution: dampers are fixedly connected to the four corners of the top of the movable seat, and the top of the dampers is fixedly connected to the placement seat.

[0011] By adopting the above technical solutions, the damper can further assist in buffering and fixing the mounting base, ensuring the stability of the device in multiple ways during stationary or moving processes.

[0012] As a further description of the above technical solution: the handwheel is located on the outside of the placement seat, and a limit pin is provided through the handwheel.

[0013] By adopting the above technical solution, the handwheel is provided with multiple evenly distributed holes on its outside. The through-hole limit pin is inserted into the groove on the outside of the placement seat to limit the handwheel.

[0014] As a further description of the above technical solution: the bottom of the movable plate is disposed in the mounting groove, and the outside of the movable plate is slidably connected to the inner wall of the mounting groove.

[0015] By adopting the above technical solution, the mounting groove serves to limit the movement of the moving plate.

[0016] As a further description of the above technical solution: guide columns are fixedly connected to both sides of the U-shaped frame, and the guide columns are slidably connected to both sides of the clamping plate.

[0017] By adopting the above technical solution, grooves are opened on both sides of the clamping plate, and the two sides of the clamping plate can slide along the guide post through the grooves.

[0018] As a further description of the above technical solution: a protective cover is fixedly connected to the top of the placement seat, and the perfluorohexanone bottle is placed inside the protective cover.

[0019] By adopting the above technical solution, the protective cover serves to protect the perfluorohexanone bottle.

[0020] As a further description of the above technical solution: a handle is fixedly connected to the left side of the movable seat.

[0021] By adopting the above technical solution, the perfluorohexanone bottle can be moved by using a handle in conjunction with casters.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. This utility model provides a novel, easily replaceable water mist perfluorohexanone fire extinguishing device. Firstly, the handle, casters, slide rail, slider, spring damper, support rod, placement base, and damper work together. The handle and casters allow the perfluorohexanone bottle to be moved. During transport, when encountering bumpy roads or uneven ground, the spring damper in the buffer assembly absorbs vibration energy, preventing direct transmission of vibration to the perfluorohexanone bottle. Simultaneously, the support rod, rotatably connected to the bottom of the placement base, functions under horizontal force, adjusting its angle to maintain the balance and stability of the placement base, ensuring the safety of the bottle.

[0024] 2. This utility model provides a novel water mist perfluorohexanone fire extinguishing device that is easy to replace. The device works in cooperation with a base, mounting groove, bidirectional threaded rod, handwheel, moving plate, clamping plate, U-shaped frame, guide column, protective cover, spring, and groove. The bidirectional threaded rod can drive the two moving plates and U-shaped frame to move relative to each other or in opposite directions, which facilitates the replacement and installation of the fire extinguishing device. Furthermore, the clamping plate, under the combined action of spring force and threaded transmission, gently and firmly clamps the new bottle, ensuring that the bottle will not shake or shift during subsequent use and movement.

[0030] 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.

[0031] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0032] Reference Figure 1-4 This utility model discloses a novel water mist perfluorohexanone fire extinguishing device that is easy to replace. It includes a movable base 1 for support, with two sliding grooves 2 on its top. A buffer assembly is installed within each groove 2, and a placement seat 6 is connected to the top of the buffer assembly. The placement seat 6 has a groove on its top for placing the perfluorohexanone bottle 19. An installation groove 8 is provided on the top of the placement seat 6, through which a bidirectional threaded rod 9 is rotatably connected. A handwheel 10 is fixedly connected to the rear end of the bidirectional threaded rod 9, allowing the handwheel 10 to rotate the bidirectional threaded rod 9. Both sides of the outer ring of the rod 9 are threaded with movable plates 11. Each movable plate 11 has a clamping plate 12 fixedly connected to its top. The bidirectional threaded rod 9 can drive the two movable plates 11 and clamping plates 12 to move relative to or away from each other. A U-shaped frame 13 is provided on the outer side of the clamping plate 12. Multiple springs 16 are fixedly connected to the inner side of the U-shaped frame 13, with the other end of each spring 16 fixedly connected to the clamping plate 12. The compression of the springs 16 causes the U-shaped frame 13 to retract. Two grooves 17 are provided on adjacent sides of the two U-shaped frames 13, with anti-slip pads inside to improve stability. A perfluorohexanone bottle 19 is provided in each of the two grooves 17. A connecting head 20 is fixedly connected to the top of the perfluorohexanone bottle 19, and a spray pipe 21 is fixedly connected to the outside of the connecting head 20. A nozzle 22 is fixedly connected to the end of the spray pipe 21, enabling water mist fire extinguishing. Universal wheels 24 are fixedly connected to the four corners of the bottom of the movable base 1 for easy movement.

[0033] Reference Figure 2The buffer assembly includes two sliders 3, both of which are set in the slide groove 2. Each of the two sliders 3 is rotatably connected to a support rod 5 on an adjacent side. Each of the two support rods 5 is rotatably connected to the bottom of the placement seat 6 at an adjacent end. Each of the two sliders 3 is provided with a spring damper 4 on an opposite side, and the spring damper 4 is set in the slide groove 2. When encountering bumpy roads or being placed on uneven ground during transportation, the spring damper 4 of the buffer assembly can absorb vibration energy and prevent vibration from being directly transmitted to the perfluorohexanone bottle 19 above.

[0034] Reference Figure 2 and Figure 3 Dampers 7 are fixedly connected to the four corners of the top of the movable base 1, and the top of the dampers 7 is fixedly connected to the placement base 6. The dampers 7 can further assist in buffering and fixing the placement base 6, ensuring the stability of the device in multiple directions during stationary or moving processes. The handwheel 10 is located on the outside of the placement base 6, and a limit pin 18 is provided through the handwheel 10. Multiple evenly distributed holes are provided on the outside of the handwheel 10. The limit pin 18 passes through the holes and is inserted into the groove on the outside of the placement base 6 to limit the handwheel 10. The bottom of the movable plate 11 is located in the mounting groove 8, and the outside of the movable plate 11 is slidably connected to the inner wall of the mounting groove 8. The mounting groove 8 serves to limit the movable plate 11. Guide posts 14 are fixedly connected to both sides of the U-shaped frame 13. The outside of the guide posts 14 is slidably connected to both sides of the clamping plate 12. The clamping plate 12 has grooves on both sides, and the clamping plate 12 can slide along the guide posts 14 through the grooves. A protective cover 15 is fixedly connected to the top of the placement base 6, and the perfluorohexanone bottle 19 is placed inside the protective cover 15, which serves to protect the perfluorohexanone bottle 19. A handle 23 is fixedly connected to the left side of the movable base 1.

[0035] Working Principle: When not in use, the device relies primarily on the four casters 24 at the bottom corners for flexible movement. Its direction of travel can be easily controlled via the handle 23 on the left side, allowing it to be easily pushed to various potential fire-risk areas such as warehouses and server rooms. At this time, the placement base 6 is located above the moving base 1, connected by a unique buffer assembly. During transport, when encountering bumpy surfaces, the spring damper 4 absorbs vibration energy, preventing direct transmission of vibration to the perfluorohexanone bottle 19 above. Simultaneously, the slider 3, rotatably connected to the support rod 5 at the bottom of the placement base 6, functions under horizontal force, maintaining the balance and stability of the placement base 6 through adaptive angle adjustments, ensuring the safety of the bottle. Furthermore, the dampers 7 fixedly connected to the four corners of the top of the moving base 1 further assist in buffering and securing the placement base 6, ensuring the stability of the device from multiple directions, whether stationary or in motion. The protective cover 15 on top of the placement base 6 adds an extra layer of protection to the perfluorohexanone bottle 19, blocking potential collisions, dust, and debris, ensuring the bottle's appearance and internal structure remain undamaged and always in good working order. During fire extinguishing, the extinguishing agent inside the perfluorohexanone cylinder 19, driven by a specific mechanism (commonly a high-pressure gas propellant within the cylinder itself, or power delivery via an external pump, depending on the device design), enters the spray pipe 21 through the connector 20. The spray pipe 21 serves as a delivery channel, precisely guiding the liquid perfluorohexanone to the nozzle 22 at the end. The nozzle 22 is a crucial element in achieving fire extinguishing; utilizing its precisely designed internal structure and fluid dynamics principles, it instantly breaks down and atomizes the flowing liquid perfluorohexanone, transforming it into tiny droplets that are then sprayed outwards at high speed in a dense fog-like manner. These droplets provide multiple fire extinguishing effects at the fire scene. When the extinguishing agent in the bottle is depleted or needs to be replaced regularly, turning the handwheel 10 drives the bidirectional threaded rod 9 to rotate. The bidirectional threaded rod 9 drives the two moving plates 11 and the clamping plate 12 to move in opposite directions, allowing the perfluorohexanone bottle 19 to be quickly removed for replacement. During installation, the perfluorohexanone bottle 19 is placed in the groove at the top of the placement seat 6. Then, turning the handwheel 10 drives the two clamping plates 12 to move relative to each other. The clamping plates 12 drive the two U-shaped frames 13 and the groove 17 to move relative to each other, clamping the perfluorohexanone bottle 19 externally. The retraction of the spring 16 allows the U-shaped frames 13 to retract, gently and firmly clamping the new bottle. After installation, the limiting pin 18 is inserted through the hole in the handwheel 10 into the groove on the outside of the placement seat 6 to limit the handwheel 10 and improve stability.
