Referring to fig. 1, 2, 3, 4, 5 and 6, when the fire hydrant needs to be used, the rotating rod 6 is difficult to rotate due to rust generated when the fire hydrant body 1 is not used for a long time, at this time, the air outlet pipe 151 is manually rotated, the air inlet end of the air outlet pipe 151 faces the movable cavity 15 and inflates the air bag 13 inside the water storage cavity 2 through the inflation joint 11, so that the air bag 13 is expanded and the air inside the air bag 13 is squeezed by the overpressure to enter the air outlet groove 14 and finally enter the movable cavity 15, the bearing 61 is driven to rotate by the rotation of the air blowing fan blade 62, the bearing 61 is continuously rotated to generate heat by continuously inflating the air bag 13, the heat generated by the bearing 61 causes the iron rust around the rotating rod 6 to loosen, so that the rotating rod 6 is convenient to rotate, and meanwhile, the air inside the movable cavity 15 enters the air outlet groove 41 through the air outlet groove 152, and through the design of the exhaust groove 41, the gas pressure entering the exhaust groove 41 changes to generate vibration, the vibration generated through the gas pressure change causes the iron rust generated at the contact part of the ball valve 4 and the inner wall of the water storage cavity 2 to loosen, the torque required by the rotating handle 7 is reduced, the opening time of the fire hydrant body 1 is shortened, and the probability of fire spreading is reduced, when the fire hydrant body 1 is not placed, in order to detect the fire hydrant body 1, the air bag inside the water storage cavity 2 is only needed to be inflated through the inflation connector 11, and the air outlet pipe 151 is manually rotated to enable the air inlet of the air outlet pipe 151 to face the air outlet groove 14, if the interior of the fire hydrant is not blocked by the iron rust, the gas inside the air bag 13 enters the air outlet pipe 151 under the action of the water pressure, and the air flow enters the air outlet pipe 151, and through the design of the air outlet pipe 151, the air pressure change generates vibration and makes sound when the air flow enters the air outlet pipe 151, if the interior of the hydrant is blocked by rust, the exhaust speed of the air flow in the air bag 13 is slow, and when the air flow enters the air outlet pipe 151, vibration cannot be generated due to the slow air flow, so that sound cannot be generated, and the detection of the hydrant is realized.
The using method of the invention has the following working principle:
firstly, when the fire hydrant is detected, only the air bag 13 in the fire hydrant body 1 needs to be inflated at the inflation connector 11, so that the air bag 13 is expanded, if the interior of the fire hydrant body 1 is not blocked by rust, water pressure acts on the air bag 13, the baffle plate 122 is reset by the elastic hinge 121 to block the air inlet groove 12, so that the air in the air bag 13 can only enter the air outlet groove 14 when being squeezed by water, at the moment, the air inlet end of the air outlet pipe 151 is manually rotated towards the air outlet groove 14, so that the air enters the air outlet pipe 151, through the design of the air outlet pipe 151, the pressure of the air entering the air outlet pipe 151 is changed to generate vibration and sound, if the interior of the fire hydrant body 1 is blocked by the rust, the air bag 13 is slowly exhausted without the water pressure, and the air is not enough to generate vibration when entering the interior of the air outlet pipe 151, so that the sound is not generated, with this realization to fire hydrant body 1 detect, secondly, when needing the water source rescue conflagration, only need manually rotate the inlet port of outlet duct 151 towards activity chamber 15, and aerify the gasbag through inflation joint 11, make the inside gas of gasbag 13 finally transmit to activity chamber 15 inside and blow fan blade 62 and rotate through air outlet groove 14, drive bearing 61 through fan blade 62 simultaneously and rotate, it makes bearing 61 continuously rotate and produce the heat to aerify to gasbag 13 to last, make the iron rust that bull stick 6 place produced take place to become flexible through the produced heat of bearing 61, the inside gas of activity chamber 15 transmits to inside exhaust duct 41 through air discharge duct 152 simultaneously, and through the design of exhaust duct 41. Make the gas pressure that gets into inside exhaust duct 41 change and produce the vibration, make ball valve 4 become flexible with the produced iron rust of water cavity 2 inner wall contact part through the vibration that the inside gas of exhaust duct 41 produced because of pressure variation for bull stick 6 is rotated easily when rotating 7, has reduced the fire hydrant and has opened the required moment of time thereof, has shortened the time that the fire hydrant opened, and has reduced the probability that the condition of a fire spreads.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
