Problems solved by technology
[0003] Most of the existing outdoor fire hydrants are columnar fire hydrants exposed above the ground. In order to remind pedestrians and vehicles, red or other brightly colored paints are often painted on their surfaces, but pedestrians or vehicles often hit the fire hydrants by mistake. The occurrence of accidents will easily lead to damage to the fire hydrant, so that the fire hydrant cannot supply water normally, and the outdoor fire hydrant is prone to rust after being exposed to wind and rain, making it difficult to open or close the water outlet of the fire hydrant The phenomenon

The invention provides an outdoor crash-proof underground fire hydrant based on rotation limitation, and relates to the technical field of fire-fighting equipment. The outdoor crash-proof undergroundfire hydrant based on rotation limitation comprises a ground, and a water receiving pipe is fixedly arranged at the bottom of the ground. A transverse plate is fixedly arranged at the top end of the water receiving pipe, and a sleeve is fixedly arranged at the top end of the transverse plate. A lifting pipe is glidingly connected in the sleeve, and a disc is fixedly arranged on the periphery of the lifting pipe. According to the outdoor crash-proof underground fire hydrant based on rotation limitation, the fire hydrant can be arranged below the ground and a cover plate can be protected to avoid the collision between people and vehicles and the fire hydrant, so the safety of the fire hydrant is improved, the normal use of the fire hydrant is ensured, the corrosion of the fire hydrant is decelerated, and the service life of the fire hydrant is prolonged. Moreover, a water outlet can move up and down and can extend above the ground during taking water, so the connection of a water hose and the water outlet is facilitated.
Description
technical field [0001] The invention relates to the technical field of fire-fighting facilities, in particular to an outdoor anti-collision underground fire hydrant based on rotation and positioning. Background technique [0002] The outdoor fire hydrant is a water supply facility installed on the underground fire water supply network near the building and beside the road. It is mainly used by fire trucks and cleaning vehicles. One of the important fire fighting facilities. [0003] Most of the existing outdoor fire hydrants are columnar fire hydrants exposed above the ground. In order to remind pedestrians and vehicles, the surface is often coated with red or other brightly colored paints, but pedestrians or vehicles often hit the fire hydrants by mistake. The occurrence of accidents will easily lead to damage to the fire hydrant, so that the fire hydrant cannot supply water normally, and the outdoor fire hydrant is prone to rust after being exposed to wind and rain, makin...
