[0002] A ground fire hydrant is an outdoor fire water supply facility that is installed directly above the ground. It is mainly composed of a valve, a water outlet and a hydrant body. Since part of its shell is exposed to the ground, it can be quickly found and used in the event of a fire. It is easy to operate, quick and efficient, and can effectively control the spread of fire. The main components of a ground fire hydrant include a valve, a water outlet and a hydrant body. Its water inlet is usually connected to the city's tap water network, and fire water is provided through the valve and the outlet. The design of the ground fire hydrant makes it very convenient and quick in water discharge operation. It is the main water supply facility for fire brigades to extinguish fires. The advantages of ground fire hydrants include easy installation, quick operation and the ability to quickly provide water in an emergency. Since it is directly exposed to the surface, it is very obvious, so it can be quickly found and used in the event of a fire, effectively controlling the spread of fire. In addition, the ground fire hydrant has a simple structure, is easy to maintain, and is suitable for use in various environments. However, the existing ground fire hydrants have average impact resistance and are not convenient for protecting the valves, which affects the service life of the valves.

[0003] For example, the announcement number is CN212026444U, which discloses a ground fire hydrant, comprising an upper bolt body, a lower bolt body, a breakable bolt, an upper connecting rod, a lower connecting rod, and a connecting head, wherein one end of the lower connecting rod is inserted into the lower portion of the connecting head, a first coupling knot is fixedly connected to the upper portion of the connecting head, a second coupling knot is fixedly connected to the upper connecting rod near the connecting head, the second coupling knot presses against the first coupling knot, the upper connecting rod is provided with a pressing step arranged around the outer wall of the upper connecting rod, a pressing block is provided at the upper end of the upper bolt body, a pressing spring is sleeved on the upper connecting rod, one end of the pressing spring presses against the pressing step, and the other end of the pressing spring presses against the pressing block. The pressing spring applies a downward force to the upper connecting rod, so that the second coupling knot can be firmly pressed against the first coupling knot when it tips over or rolls during transportation or installation.

[0004] The above-mentioned above-ground fire hydrant has average impact resistance during use and is not convenient for protecting the valve, which affects the service life of the valve. Utility Model Content
