Description

Technical Field

[0001] This utility model relates to the technical field of fire protection facilities, and in particular to an indoor fixed fire extinguishing device. Background Technology

[0002] Fire hose reel systems are a common building fire extinguishing facility, frequently seen in daily life. The fire hose reel box is the end of the system and a crucial component for direct water spraying in fire suppression.

[0003] In actual use, the fire hose is pulled out for fire extinguishing. After use, the hose is directly wound onto the reel. At this time, the surface of the hose may be covered with dust and debris. Therefore, the cleanliness of the rewound hose is poor, and there is a risk of bacterial growth, which is not conducive to long-term storage and subsequent use. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the present invention provides an indoor fixed fire extinguishing device.

[0005] The indoor fixed fire extinguishing device provided by this utility model adopts the following technical solution:

[0006] An indoor fixed fire extinguishing device includes a fire box containing a fire hose reel. The fire hose reel includes two fixedly mounted outer reels, with a connecting shaft rotatably passing between them. Two inner reels are fitted and fixedly connected to the connecting shaft, located between the two outer reels. A fire hose is wound around the connecting shaft. A handle is installed at one end of the connecting shaft, a spray gun is installed at one end of the fire hose, and a water supply pipe is connected to the other end of the fire hose. A connecting plate is installed on the outer wall of the outer reels, and a guide frame is fixedly connected between the two connecting plates. A brush is installed on the inner wall of the guide frame, and the fire hose passes through the guide frame.

[0007] By adopting the above technical solution, when the fire hose is rolled up, the brush continuously cleans the sewage and impurities on the surface of the fire hose, so that the fire hose remains clean after being rolled up.

[0008] Optionally, a roller is rotatably connected to the inner wall of the guide frame. The roller is located on the side of the brush near the outer disc and makes rolling contact with the fire hose.

[0009] By adopting the above technical solution, the roller is used to roll and support the fire hose, which effectively improves the smoothness of the fire hose during winding or unwinding.

[0010] Optionally, a sliding groove is provided on the outer wall of the outer plate from top to bottom. The sliding groove is arranged circumferentially around the connecting shaft. A positioning screw is slidably installed in the sliding groove. The positioning screw passes through the connecting plate and is fixed by a positioning nut.

[0011] By adopting the above technical solution, it is easy to adjust the unwinding direction of the fire hose to adapt to different usage environments.

[0012] Optionally, a vacuum breaker is installed on the water supply pipe.

[0013] By adopting the above technical solution, the installation of the vacuum breaker reduces the risk of water backflow and contamination within the reel.

[0014] In summary, this utility model has at least one of the following beneficial technical effects:

[0015] 1. When rewinding the fire hose, the brush continuously cleans the surface of the fire hose to remove sewage and impurities, so that the fire hose remains clean after being rewound;

[0016] 2. The roller is used to roll and support the fire hose, which effectively improves the smoothness of the fire hose during winding or unwinding;

[0017] 3. The vacuum breaker reduces the risk of water backflow and contamination within the reel. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 The present invention will be described in further detail below.

[0024] This utility model discloses an indoor fixed fire extinguishing device. (Refer to...) Figure 1The indoor fixed fire extinguishing device includes a fire box 1, a fire hose reel 2 is rotatably installed inside the fire box 1, a fire hose 3 is wound on the fire hose reel 2, a spray gun 4 is installed at the water outlet of the fire hose 3, a water supply pipe 5 is connected to the water inlet of the fire hose 3, and a vacuum breaker 6 is also installed on the water supply pipe 5 to limit water backflow and prevent pollution.

[0025] Reference Figure 1 and Figure 2 The fire hose reel 2 includes two fixedly installed outer reels 20. A connecting shaft 200 is rotatably inserted between the outer reels 20. One end of the connecting shaft 200 passes through the outer reels 20 and is equipped with a handle 201. Two inner reels 21 are fixedly fitted onto the connecting shaft 200. The two inner reels 21 are located between the two outer reels 20. The fire hose 3 is wound around the connecting shaft 200 and is located between the two inner reels 21.

[0026] Reference Figure 1 and Figure 2 An mounting bracket 22 is fixedly connected to the outer disc 20. The mounting bracket 22 is hinged to the inner wall of the fire box 1, allowing the fire hose reel 2 to rotate outward from the fire box 1. A sliding groove 202 is provided on the outer wall of the outer disc 20, which is arranged circumferentially around the connecting shaft 200 from top to bottom. A connecting plate 23 is provided on the outer side of the outer disc 20 corresponding to the sliding groove 202. A positioning screw 24 is slidably installed in the sliding groove 202. The positioning screw 24 passes through the connecting plate 23 and is fixed by a positioning nut 25. A rectangular guide frame 26 is fixed between the two connecting plates 23. The fire hose 3 passes through the guide frame 26, and a gap is provided between the guide frame 26 and the edge of the outer disc 20.

[0027] Reference Figure 3 and Figure 4 Four L-shaped mounting plates 27 are fixedly attached to the side of the guide frame 26 near the outer plate 20. The four mounting plates 27 are located at the four corners of the guide frame 26. A roller 28 is rotatably connected between two adjacent mounting plates 27, and the fire hose 3 rolls in contact with the roller 28. Four brushes 29 are installed on the side of the guide frame 26 away from the outer plate 20.
