[0002] Fire hydrant cabinets are devices used to store fire hoses. They are generally installed in the wall. Depending on the installation method, they are divided into surface-mounted, concealed-mounted, and semi-concealed-mounted types.

[0003] Existing fire hydrant cabinets have a relatively limited capacity for storing fire hoses during use. For example, Chinese Patent Publication No. CN219090948U discloses a fire hydrant cabinet for fire protection engineering. The cabinet's inner bottom wall is fixedly connected to a limit box, which has a certain height. A rotating column is located above the limit box. The distance between the limit box and the rotating column determines the maximum diameter of the fire hose that can be reeled. In other words, the distance between the limit box and the rotating column determines the maximum length of the fire hose that can be reeled. Due to the certain height of the limit box, the distance between the limit box and the rotating column becomes relatively limited, which affects the maximum length of the fire hose that can be reeled, resulting in significant waste of internal space within the cabinet. Accordingly, the present application proposes a fire hydrant cabinet for fire protection engineering. Utility Model Content

[0023] Reference Figure 1-6 , a fire hydrant cabinet for fire protection engineering, including a box body 2, an L-shaped limit block 9 is fixedly connected to the inside of the box body 2, the number of the L-shaped limit block 9 is two, the material of the L-shaped limit block 9 is aluminum alloy, the L-shaped limit block 9 is fixedly connected to the box body 2 by welding, the L-shaped limit block 9 is used to clamp the sprinkler head of the fire hose, when the device is completed after winding, the sprinkler head can be clamped through the gap between the two L-shaped limit blocks 9 to facilitate the next use, the limit column 23, the limit column 23 is slid in the side wall of the box body 2, when the limit column 23 is pushed upward, the limit column 23 can completely slide into the side wall of the box body 2, under the action of gravity, the limit column 23 will fall again,

[0024] The front end of the box body 2 is rotatably connected with the protective door 1. The material of the protective door 1 and the box body 2 is aluminum alloy. The protective door 1 and the box body 2 are formed by stamping.

[0025] A large limit plate 3 is fixedly connected to the side wall of the protective door 1, and a small limit plate 5 is fixedly connected to the side wall of the box body 2 behind the large limit plate 3. A limit rod 4 is arranged in the large limit plate 3, and the limit rod 4 passes through the large limit plate 3 and the small limit plate 5. A storage wheel 16 is rotatably connected to the inner center of the box body 2. There is a certain gap between the pressure plate 13 and the storage wheel 16. The purpose of setting this gap is to facilitate the installation of the pressure plate 13 when winding up the fire hose.

[0026] A clamping shaft 11 is fixedly connected above the storage wheel 16 near the upper right corner of the box body 2. The clamping shaft 11 and the pressure block 18 are used to limit the storage wheel 16. When the pressure block 18 is pressed downward and then rotated to the horizontal part of the lower end of the positioning groove 21, the pressure block 18 will press the blocking block 17 downward. At this time, the front end of the blocking block 17 will be pressed into the limiting groove 15, locking the position of the storage wheel 16. When the fire hose needs to be used, the pressure block 18 is rotated in the opposite direction.

A fire hydrant 10 is fixedly provided on the lower surface of the interior of the box body 2. The fire hydrant 10 is a prior art and is used to supply water to the fire hose. It is usually connected to the water outlet of the water pipe. The purpose of being arranged near the fire hose is to facilitate the use of water to extinguish the fire as soon as possible.

[0030] When using this device, first remove the two positioning rods 14, then the pressure plate 13, and then place the fire hose in the position of the original pressure plate 13, then press the pressure plate 13 down, and then push the limit column 23 upwards, and then pass the fire hose through the two pressure plates 7, by adjusting the position between the pressure plates 7, so that the pressure roller 8 can be pressed on the fire hose, and then tighten the nut 6 to fix the position of the pressure plates 7, and then rotate the storage wheel 16 through the storage rod 12 so that the fire hose can be wound on the storage wheel 16. The pressure roller 8 can rotate. When the fire hose passes through When passing between the water pressure rollers 8, the water pressure rollers 8 will squeeze out the water in the used fire hose. When use is completed, loosen the nut 6, then move the limit column 23 upwards, and pull out the fire hose. The sprinkler head on the fire hose is clamped between the L-shaped limit blocks 9, and then press the pressing block 18 downward and rotate it to press the front end of the clamping block 17 into the limit groove 15, and then slide the limit rod 4 upward. At this time, the limit rod 4 can be pulled out, and then close the protective door 1, and then insert the limit rod 4 between the large limit plate 3 and the small limit plate 5 to complete the use of this device.
