Description

Fire hydrant water pressure monitoring facilities

Technical Field

The utility model relates to a fire-fighting equipment technical field, concretely relates to fire hydrant water pressure monitoring facilities.

Background

Fire hydrants are one of the necessary devices for urban fire suppression systems. When a fire occurs, if the water pressure in the fire hydrant is insufficient, the fire fighting opportunity is missed, and a great loss is caused. Therefore, real-time monitoring of the water pressure within the hydrant is essential.

The existing fire hydrant water pressure monitoring equipment is directly contacted with water in a fire hydrant through a pressure sensor, so that the water pressure in the fire hydrant is measured. However, since the pressure sensor is in direct contact with water in the hydrant, it is inconvenient to take out and replace the pressure sensor when the pressure sensor is damaged.

The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In the description of the present application, it is to be understood that the terms "longitudinal," "lateral," "horizontal," "top," "bottom," "upper," "lower," "inner" and "outer" and the like are used in the orientation or positional relationship shown in the drawings, which are used for convenience in describing the present invention and for simplicity in description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

As shown in fig. 1-5, the utility model provides a fire hydrant water pressure monitoring facilities, including box 10, piston rod 20, controller 30, fixed block 40, alarm 50, transmitter 60 and pressure sensor 70.

The case 10 is provided on one side of the hydrant 90 and is integrally formed with the hydrant 90. The inner cavity of the box body 10 is communicated with the inner cavity of the fire hydrant 90 through the communication hole 15, and the inner cavity of the box body 10 is arranged at the top of the box body 10 in an opening mode and forms an opening 11. The top of the box 10 is provided with a cover 12, one side of the cover 12 is hinged with one side of the top of the box 10, and the other side of the cover 12 is detachably connected with the other side of the top of the box 10. The cover 12 is used to close the opening 11 to protect the components in the inner cavity of the box 10.

One end of the piston rod 20 is disposed in the communication hole 15, and the other end thereof extends into the inner cavity of the case 10 after passing through the communication hole 15. The piston rod 20 can move in the communication hole 15 and keep a seal with the hole wall of the communication hole 15 all the time during the movement to prevent water in the hydrant 90 from entering the tank 10.

The controller 30, the fixed block 40, the alarm 50 and the emitter 60 are all fixedly arranged in the inner cavity of the box body 10. The fixed block 40, the alarm 50 and the emitter 60 are all electrically connected with the controller 30, and the alarm 50 is preferably an audible and visual alarm. The pressure sensor 70 is provided between the piston rod 20 and the fixed block 40, and specifically, one end of the pressure sensor 70 is fixedly connected to the other end of the piston rod 20, and the other end abuts against the fixed block 40.

The specific working process is as follows: the water under pressure in the hydrant 90 presses the piston rod 20, and the piston rod 20 presses the pressure sensor 70 between the fixed block 40, so the design of the piston rod 20 plays a role of transferring the water pressure, and prevents the pressure sensor 70 from directly contacting the water in the hydrant 90. The pressure sensor 70 transmits the detected water pressure value in the fire hydrant 90 to the controller 30, the controller 30 compares the water pressure value with a preset alarm value, if the water pressure value is higher than or lower than the alarm value, the controller 30 controls the alarm 50 to alarm, and simultaneously sends alarm information to a terminal through the emitter 60 to remind a manager to check and maintain before.

In addition, when the pressure sensor 70 is damaged, the maintenance personnel only need to close the water stop valve on the water pipe communicated with the fire hydrant 90 and then directly replace the damaged pressure sensor 70 in the box body 10, and since the pressure sensor 70 is not in direct contact with the water in the fire hydrant 90, the pressure sensor 70 is conveniently taken out and replaced.

In one embodiment, the other side of the cover 12 and the other side of the top of the case 10 are both provided with locking holes 13. The other side of the cover body 12 is provided with a padlock which is locked in the two lock holes 13. Normally, the box body 10 is closed by a padlock, so that pedestrians or children are prevented from opening the box body 10 at will and damaging parts in the box body 10. When the maintenance personnel need to maintain, the key is opened by a portable key.

In one embodiment, a groove 14 is formed on a side wall of the box body 10 away from the hydrant 90, a display 80 is fixedly arranged in the groove 14, and the display 80 is electrically connected with the controller 30. The controller 30 converts the received water pressure value and displays the converted value on the display screen 80, which is convenient for people to observe. When a fire occurs, the fire fighter or the fire suppression personnel can directly know the water pressure value in the fire hydrant 90 by observing the display screen 80, so that the follow-up fire extinguishing judgment can be conveniently made at once.

In one embodiment, the outer circumferential surface of the piston rod 20 is formed with an inwardly extending seal groove 21. A sealing ring 22 is arranged between the piston rod 20 and the hole wall of the communication hole 15, and the sealing ring 22 is positioned in the sealing groove 21. The inner side of the sealing ring 22 is fixedly connected with the groove wall of the sealing groove 21 of the piston rod 20, and the outer side of the sealing ring is tightly attached to the hole wall of the communicating hole 15. The sealing ring 22 is designed to further improve the sealing between the piston rod 20 and the wall of the communication hole 15 to prevent water in the hydrant 90 from entering the tank 10.
