Description

Technical Field

[0001] The utility model relates to the field of fire hydrants, in particular to a convenient-operation intelligent fire hydrant indoor. Background Art

[0002] Indoor fire hydrants are a type of fixed firefighting tool, which are mainly used to control combustibles, isolate combustible materials and eliminate fire sources. Existing firefighting systems include outdoor fire hydrant systems, indoor fire hydrant systems and fire extinguisher systems. Among them, indoor fire hydrants are interfaces with valves that supply water to the fire scene through indoor pipelines. They are used as indoor fixed firefighting facilities in buildings, etc. They are usually installed in fire hydrant boxes and are used in conjunction with fire hoses, water guns, fire hose reels and other equipment.

[0003] The existing indoor fire hydrants do not have the function of telescopic movement. The fire hydrants are fixed in the fire box, so that when the fire hose is used to extinguish the fire, the fire hose will rub and squeeze the corners of the fire box. In severe cases, a bent part will be formed, resulting in insufficient water supply to the fire hose. At the same time, the internal space of the fire box is small, and subsequent maintenance of the fire hydrant is inconvenient, which is inconvenient for people to use and reduces the convenient operability of the indoor fire hydrant. Therefore, it is urgent to develop an intelligent fire indoor hydrant that can be telescopically adjusted to prevent the fire hose from rubbing and squeezing the corners of the fire box and facilitate the subsequent maintenance of the fire hydrant.

[0020] The water inlet hole at the lower end of the bolt body 1 is located on one side of the outer diameter surface of the bolt body 1, and a telescopic tube 9 is fixedly arranged at the water inlet hole, and a water through hole 91 connected to the central cavity of the bolt body 1 is arranged in the center of the telescopic tube 9; a fixed tube 10 is also arranged on one side of the telescopic tube 9, and the fixed tube 10 is fixedly connected to the water delivery pipeline through a thread; a protruding sliding shaft section is arranged at the end of the telescopic tube 9 away from the bolt body 1; the telescopic tube 9 is slidably arranged in the central through hole of the fixed tube 10 through the sliding shaft section, and a sealing ring 11 is fixedly arranged at the sliding cooperation between the telescopic tube 9 and the fixed tube 10; the fixed tube 10 is fixedly connected to a limited retaining ring 12 on the side close to the bolt body 1, and a mounting hole is arranged on the outer diameter surface of the limited retaining ring 12, and a locking structure 13 for locking the telescopic tube 9 and the fixed tube 10 is fixedly arranged in the mounting hole;

[0021] The telescopic tube 9 is provided with a slide groove 92 on the outer diameter surface of the side close to the locking structure 13, and a clamping groove 93 is provided at the bottom of the slide groove 92 close to the bolt body 1;

[0022] The locking structure 13 includes a clamping shaft 131 slidably installed in the mounting hole of the limit retaining ring 12, one end of the clamping shaft 131 extends into the clamping groove 93 of the telescopic tube 9, and the other end of the clamping shaft 131 extends to the outside of the limit retaining ring 12; a locking block 132 for limiting the clamping shaft 131 is also fixedly provided on the mounting hole; a spring 133 is fixedly provided between the locking block 132 and the clamping shaft 131.

[0023] Working principle:

[0024] The fire hydrant of the utility model is fixedly installed in the fire box, and the fixed pipe 10 is fixedly connected to the water supply pipe. When using the fire hydrant of the utility model, the fire hose buckle is buckled with the pipe tooth interface 8 on the fire hydrant, and then the hand wheel 5 on the fire hydrant is turned to make the valve stem 4 drive the sealing valve disc 6 to move downward, and the water flows out from the opening between the sealing valve disc 6 and the sealing seat ring 7, and flows into the fire hose through the water outlet for fire fighting; when the water flows into the fire hose for use, the clamping shaft 131 on the locking structure 13 can be pulled up to make the lower end of the clamping shaft 131 disengage from the clamping groove 93 provided on the telescopic tube 9, and the lower end of the clamping shaft 131 enters the slide groove 92 provided on the telescopic tube 9, and then the fire hydrant body 1 can be pulled outward to move the fire hydrant body 1 to the outside of the fire box, which is convenient for use and prevents friction between the fire hose and the fire box.

[0025] After the fire is extinguished, the fire hydrant body 1 can be pushed inward to retract it into the fire hydrant box. After the fire hydrant body 1 moves to a suitable position, the clamping shaft 131 is re-inserted into the clamping groove 93 under the action of the spring 133 to lock and fix the telescopic tube 9 and the fixed tube 10. Then, the hand wheel 5 is turned to close the fire hydrant. When the lower end of the clamping shaft 131 is disengaged from the clamping groove 93 provided on the telescopic tube 9, the lower end of the clamping shaft 131 enters into the slide groove 92 provided on the telescopic tube 9, and the telescopic tube 9 and the fixed tube 10 are guided and limited by the clamping shaft 131 and the slide groove 92 to prevent circumferential rotation.

[0026] At the same time, when the fire hydrant needs to be inspected, the clamping shaft 131 on the locking structure 13 can also be pulled out to make the lower end of the clamping shaft 131 and the clamping groove 93 set on the telescopic tube 9 fall off, and then the fire hydrant body 1 can be pulled outward to move the fire hydrant body 1 to the outside of the fire box, which is convenient for the inspection of the fire hydrant.

[0027] Although the present disclosure has been described in detail with reference to the exemplary embodiments, the present disclosure is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes may be made thereto without departing from the scope of the present disclosure.
