It is a kind of to limit the Anti-collision fire hydrant for rolling connection based on ball
Technical field
It is specially a kind of that the Anti-collision fire hydrant for rolling connection is limited based on ball the present invention relates to technical field of fire control.
Background technique
Fire hydrant, formal call are fire hydrant, are a kind of fixed fire fighting devices, main function be control combustible, every
Exhausted oxidizer eliminates ignition source, is broadly divided into indoor fire hydrant and outdoor fire hydrant, mainly for fire fighting truck from municipal water supply pipe network
Or fire extinguishing is implemented in the water intaking of outdoor fire fighting water supply network, can also be directly connected to water band, hydraulic giant goes out above-water method, so, indoor and outdoor disappears
It is also one of the important fire fighting device to fight a fire that fire, which ties system,.
And in order to supply water in time to fire fighting truck, outdoor fire hydrant is generally fixedly arranged at roadside, and is exposed to road
More than face, therefore it is subject to the collision of foreign matter and vehicle, but is rigid contact between traditional Outdoor Fire Hydrant and ground,
Therefore it is easy for the case where bending deformation occur after being collided, causes internal spool that can not be operated, make fire hydrant
It can not be opened, influence the normal use of fire hydrant, and the direction of the water outlet of traditional Outdoor Fire Hydrant is fixed, Wu Fagen
It is adjusted according to the difference in ignition point orientation, so that the phenomenon that water band of connection will appear bending, reduces the flow velocity of water.
To solve the above problems, now proposing a kind of Anti-collision fire hydrant for limiting based on ball and rolling connection, fire-fighting can be made
Bolt rotates, and makes the water outlet of water receiving column side towards water spraying direction is needed, and avoids bending at fire hydrant and water band connection
The generation of phenomenon, ensure that the proper flow of water flow, while can be avoided the rigid impact between water receiving column and ground, effectively slow
The deformation for having solved water receiving column ensure that the normal use of fire hydrant.
