[0002] An outdoor fire hydrant is a water supply facility installed on the fire water supply network outside a building. It is mainly used for fire trucks to draw water from the municipal water supply network or the outdoor fire water supply network for fire extinguishing. It can also be directly connected to a water hose or a water gun to discharge water for fire extinguishing. It is one of the important fire-fighting facilities for fighting fires.

[0003] However, since outdoor fire hydrants have no protective measures and are placed outdoors all year round, they are easily hit by vehicles, causing damage to the fire hydrants. Once the fire hydrants are damaged, they cannot be used when unexpected situations require fire extinguishing, endangering personal safety, and a lot of water will be wasted after damage.

[0019] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.

[0020] refer to Figure 1-3The embodiment of the utility model discloses: an impact-proof and explosion-proof fire hydrant, comprising a fire hydrant body 1, four protection plates 2, the protection plates 2 are evenly arranged around the fire hydrant body 1, the upper and lower ends of the protection plates 2 are respectively hinged with an upper shock absorber 5 and a lower shock absorber 7, the other ends of the upper shock absorber 5 and the lower shock absorber 7 are respectively arranged on the fire hydrant body 1, and a buffer rod 9 is also arranged in the middle position of the protection plate 2, the fire hydrant body 1 is provided with a sliding sleeve 11, the buffer rod 9 is slidably inserted into the sliding sleeve 11, and a first buffer spring 10 is arranged in the sliding sleeve 11, one end of the first buffer spring 10 is connected to the inside of the sliding sleeve 11, and the first buffer spring 10 is against the buffer rod 9. Among them, when the fire hydrant is hit, it first hits the protection plate 2, the protection plate 2 acts on the upper shock absorber 5 and the lower shock absorber 7, and the buffer rod 9 pushes and compresses the first buffer spring 10, thereby reducing the impact force, avoiding direct impact on the fire hydrant body 1, causing the fire hydrant to burst, thereby improving the service life of the fire hydrant.

[0021] In order to facilitate the installation and connection of the protection plate 2, a first connecting ear 4 is provided on the protection plate 2, a second connecting ear 3 is provided on the upper end of the fire hydrant body 1, the upper shock absorber 5 is provided on the first connecting ear 4 and the second connecting ear 3 by bolts and nuts, a third connecting ear 6 is provided on the protection plate 2, a fourth connecting ear 8 is provided on the lower end of the fire hydrant body 1, and the lower shock absorber 7 is provided on the third connecting ear 6 and the fourth connecting ear 8 by bolts and nuts. Among them, the upper shock absorber 5 and the lower shock absorber 7 are locked by bolts and nuts, which can facilitate the disassembly and assembly of the upper shock absorber 5 and the lower shock absorber 7, and is conducive to assembly and use.

[0022] In order to drain the water in the fire hydrant after fire fighting, thereby avoiding freezing and cracking of the fire hydrant, the fire hydrant further includes a drain pipe 12 and a dredging rod 14. The drain pipe 12 is arranged on the fire hydrant body 1 and is connected to the inside of the fire hydrant. The drain pipe 12 is located at the valve disc position inside the fire hydrant body 1. A sealing cap 13 for blocking the drain pipe 12 is threadedly connected on the drain pipe 12. A sealing ring is provided between the sealing cap 13 and the drain pipe 12. The dredging rod 14 is penetrated by the sealing cap 13.

A spring 15 is provided on the dredging rod 14, and the spring 15 is sleeved on the dredging rod 14. One end of the spring 15 is against the sealing cap 13, and the other end of the spring 15 is against the pressing handle. A sealing sleeve for preventing water leakage is also provided in the sealing cap 13. When the fire hydrant is finished being used, the sealing cap 13 is rotated to open the drain pipe 12, and the water inside the fire hydrant is discharged through the sealing cap 13. This prevents water from remaining inside the fire hydrant and freezing the fire hydrant. When the drain pipe 12 is blocked, the unblocking rod 14 is pressed, and the unblocking rod 14 penetrates into the drain pipe 12 and leads to the inside of the fire hydrant, thereby unblocking the blockage and draining the water smoothly.

[0023] In order to further buffer the impact force on the protective plate 2 and thus increase the service life of the protective plate 2, the protective plate 2 includes a sliding plate 22 and a fixed frame 21, the upper shock absorber 5 and the lower shock absorber 7 are arranged on the fixed frame 21, the sliding plate 22 is slidably arranged on the fixed frame 21, and a second buffer spring 23 is arranged between the fixed frame 21 and the sliding plate 22.

[0024] In order to further protect the protection plate 2 , an elastic layer 24 is provided on the sliding plate 22 .
