In the embodiment, the function realized by the first elastic element 50 is that, under the action of no water pressure, the first elastic element 50 drives the sealing float ball 330 to communicate with the floating rod 310 to move downward, so as to drive the floating rod 310 to move to the second position, and the floating rod 310 drives the folding warning assembly 40 to fold and form the second state. The state is judged as no water state.

[0022] The setting of the first elastic element 50 can avoid the problem that the floating rod 310 cannot descend when there is no water in the fire hydrant due to friction interference.
