DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1-Figure 4 The present invention provides the following technical solutions: a fireproof integrated power distribution cabinet, comprising a cabinet body 1, a cabinet door 2 hinged on the front side of the cabinet body 1, a perfluorohexanone fire extinguisher bottle 3 fixed to the outer wall of the cabinet body 1, a hard pipe 4, a drug hose 5 and a nozzle 10, and also comprising: an electrical component mounting frame 101, a movable mounting frame 8, a tee 9 and a driving assembly 6.

[0040] Further, by Figure 1 and Figure 2 As shown, in this embodiment, two electrical component mounting frames 101 are symmetrically fixed in the cabinet 1, the movable mounting frame 8 is located in the cabinet 1 and has the freedom of movement in the vertical direction, the tee 9 is fixed on the movable mounting frame 8, the two nozzles 10 are symmetrically fixed at both ends of the tee 9 and face the electrical component mounting frame 101, the hard pipe 4 is fixed on the cabinet 1, and one end of the hard pipe 4 is connected to the perfluorohexanone fire extinguisher bottle 3, and the other end is connected to the agent hose 5, and the other end of the agent hose 5 is connected to the tee 9, the driving assembly 6 is used to drive the movable mounting frame 8 to move in the vertical direction, and the driving assembly 6 includes a threaded screw 61 and a driving motor 62, and the threaded screw 61 is rotatably mounted in the cabinet 1 , and the threaded screw 61 passes through the movable mounting frame 8 and is connected to the movable mounting frame 8 by threaded engagement. The driving motor 62 is fixed to the top of the cabinet 1 to drive the threaded screw 61 to rotate. After adopting the above scheme, when in use, the electrical components are respectively fixed on the two electrical component mounting frames 101 on both sides, which can avoid the electrical components being too compact. When the electrical components catch fire, the perfluorohexanone fire extinguisher bottle 3 is opened, and the driving motor 62 is started at the same time. The driving motor 62 drives the threaded screw 61 to rotate. The movable mounting frame 8 drives the two nozzles 10 to move in the vertical direction under the action of threaded engagement. The nozzles 10 can spray fire extinguishing agent to electrical components at different heights, thereby improving the efficiency of fire extinguishing.

[0041] It should be noted that perfluorohexanone fire extinguishing agent will vaporize and absorb a large amount of heat at 50°C. When facing combustion, perfluorohexanone will reorganize into stable molecules to interrupt the branch chain reaction of the combustion process in the fire source, thereby inhibiting the redox reaction in the combustion process. At the same time, it absorbs heat and reduces the temperature of the fire scene. Under continuous and repeated physical and chemical effects, the flame is quickly extinguished. The application of perfluorohexanone automatic fire extinguishing device in the distribution cabinet is a prior art and will not be elaborated in this article.

[0042] Preferably, by Figure 1 As shown, in this embodiment, the driving assembly 6 also includes: guide columns 63, two guide columns 63 are symmetrically fixed in the cabinet 1, and the guide columns 63 pass through the movable mounting frame 8. After adopting the above scheme, the two guide columns 63 are used to guide the movable mounting frame 8, thereby improving the stability of the movable mounting frame 8 and preventing the movable mounting frame 8 from rotating when the threaded screw 61 rotates.

[0043] Optionally, by Figure 1 As shown, in this embodiment, it also includes: a fixing frame 7, which is fixed to the outer wall of the cabinet 1 by bolts, and the perfluorohexanone fire extinguisher bottle 3 is fixed on the fixing frame 7.

[0044] Further, by Figure 1 and Figure 3 As shown, in this embodiment, it also includes: an arc-shaped hoop body 11, a fixing block 12, a threaded rod 13 and a butterfly nut 14. The two fixing blocks 12 are symmetrically fixed to the outer wall of the fixing frame 7. The threaded rod 13 is fixed on the fixing block 12 and passes through the arc-shaped hoop body 11. The butterfly nut 14 is installed on the protruding end of the threaded rod 13 by threaded engagement. After adopting the above scheme, when installing the perfluorohexanone fire extinguisher bottle 3, the arc-shaped hoop body 11 and the fixing frame 7 are used to clamp the perfluorohexanone fire extinguisher bottle 3. After tightening the butterfly nut 14, the perfluorohexanone fire extinguisher bottle 3 can be stably clamped by the arc-shaped hoop body 11 and the fixing frame 7, thereby ensuring the stability of the installation of the perfluorohexanone fire extinguisher bottle 3 and avoiding the adjustable clamping force.

[0045] Optionally, by Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the fixing frame 7 includes: a positioning plate 71, a supporting plate 72 and a fixing foot 73. The positioning plate 71 has an arc-shaped groove 711. The supporting plate 72 is fixed to the bottom end of the positioning plate 71 for supporting the perfluorohexanone fire extinguisher bottle 3. The two fixing feet 73 are symmetrically fixed to the outer wall of the fixing frame 7, and the fixing feet 73 have fixing holes 731. After adopting the above scheme, the positioning plate 71 is fixed to the cabinet 1 with bolts, and the arc-shaped groove 711 cooperates with the arc-shaped hoop body 11 to clamp the perfluorohexanone fire extinguisher bottle 3. The supporting plate 72 is used to support the perfluorohexanone fire extinguisher bottle 3, which is convenient for the installation of the perfluorohexanone fire extinguisher bottle 3 and further improves the stability of the installation of the perfluorohexanone fire extinguisher bottle 3.

[0046] Preferably, by Figure 1 As shown, in this embodiment, there is a gap between the electrical component mounting frame 101 and the inner wall of the cabinet 1. After adopting the above design, when extinguishing a fire, it is convenient for the perfluorohexanone agent to quickly fill the inner space of the entire cabinet 1, and the front and rear sides of the electronic components are filled with perfluorohexanone agent, so the fire extinguishing efficiency is higher.

[0047] Preferably, by Figure 1 As shown, in this embodiment, the electrical component mounting frame 101 is fixed in the cabinet 1 by bolts. After adopting the above design, the installation is more convenient while ensuring the stable installation of the electrical component mounting frame 101. It is also convenient to disassemble, repair or replace the damaged electrical component mounting frame 101.

[0048] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the nozzle 10 is an atomizing nozzle, so that the perfluorohexanone agent sprayed from the nozzle 10 is in the form of mist gas, which makes it easier for the perfluorohexanone agent to quickly fill the inner space of the entire cabinet 1.

[0049] It should be noted that the drive motor 62 is a conventional device purchased on the market with a built-in power switch. Technicians in this field can make a conventional selection according to usage requirements.

[0053] When an electrical component catches fire, the perfluorohexanone fire extinguisher bottle 3 is opened and the drive motor 62 is started at the same time. The drive motor 62 drives the threaded screw 61 to rotate. The movable mounting frame 8 drives the two nozzles 10 to move in the vertical direction under the action of the thread rotation. The nozzles 10 spray mist-like perfluorohexanone agent to extinguish the electrical components at different heights, thereby improving the efficiency of fire extinguishing.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
