FIG. 2 is a perspective view showing an installation state of a fire-fighting outdoor fire hydrant according to the present invention.

1 to 3, a fire-fighting outdoor fire hydrant according to an embodiment of the present invention includes a lifting plate (not shown) installed along a space 10 formed at a lower portion of a sidewalk block 17 installed on a road, A lifting and lowering pipe 30 installed on the lifting plate 30 and slidably installed along the water pipe 12 and having a discharge port 54 and provided with an on-off valve 56; A door member 36 which is openably and closably provided on the entrance side of the space portion 10 so as to open and close the space portion 10, Closing cylinder 38 for pushing or pulling the cylinder 36 and pushing or pulling the cylinder 36, and a fuel supply system A working pressure supply section 70 for supplying the working fluid to the cylinder 34 and the opening and closing cylinder 38, And a switch unit (80) for transmitting the protrusion signal to the operating pressure supply unit (70).

The space portion 10 is formed by recessing the bottom surface of the lower portion of the sidewalk block 17 installed on the road in a downward direction and a concrete structure or a synthetic resin panel or a metal panel constituting the inner wall of the space portion 10 is installed Thereby forming the inner wall of the space portion 10.

A guide rail 32 is provided on the inner wall of the space portion 10 so that the lift plate 30 is slidable in the vertical direction and the lift plate 30 is formed at the center of the lift portion 30, The water pipe 12 extending upwardly extends through the lifting plate 30 and upward.

A plurality of lifting cylinders 34 are provided between the bottom surface of the lifting plate 30 and the bottom surface of the space portion 10. In this embodiment, the elevating cylinder 34 is installed at each corner of the lifting plate 30 having a rectangular shape Four elevating cylinders 34 are installed.

Accordingly, when the rod protrudes from the lifting cylinder 34, the lifting plate 30 is lifted and the fire hydrant is protruded to the ground to connect the fire hose and open the on-off valve 56 so that the fire extinguishing water can be sprayed.

A door member 36 slid sideways is provided at the upper end of the space portion 10 and a door member 36 is retracted on the inner wall of the space portion 10 opposite to the outer end portion of the door member 36 And a side surface of the door member 36 is provided with a support protrusion that protrudes in the lateral direction, and the support protrusion is connected to the rod of the opening / closing cylinder 38.

Therefore, when the rod protrudes from the opening / closing cylinder 38, the door member 36 slides toward the working space provided on the inner wall of the space portion 10, so that the upper portion of the space portion 10 is opened.

The operating pressure supply unit 70 includes a pressure vessel in which a combustible fuel is stored, an ignition plug 74 installed in the pressure vessel and providing a flame inside the pressure vessel to cause the fuel to explode, And a distribution valve 76 for distributing the working pressure to a plurality of lines to supply operating pressure.

A spark plug 74 is installed at one side of the pressure tank 72. A liquefied fuel such as petroleum is supplied to the pressure tank 72 at a predetermined pressure or higher As shown in Fig.

Accordingly, when the operator operates the switch unit 80 to operate the ignition plug 74, the flame is supplied to the pressure tank 72, so that the liquefied fuel detonates and provides operating pressure along the pipe.

The liquefied fuel stored in the pressure tank 72 is stored with a small amount of fuel so as to provide a pressure such that the rod protrudes from the lifting cylinder 34 and the opening and closing cylinder 38, It is possible to prevent safety accidents due to the explosion of the fuel.

The piping connected to the distribution valve 76 is branched from the distribution tank 76 to six or eight and connected to the four lift cylinders 34 and the two or four opening and closing cylinders 38, The pair of door members 36 are slid laterally to open the upper portion of the space portion 10, and the lifting plate 30 is lifted to the ground.

At this time, the sidewalk block 17 seated on the upper surface of the door member 36 falls to the sidewalk block 17 disposed adjacent to the sidewalk by the rising fire hydrant. Therefore, the elevating plate 30 is disposed on the upper surface of the space portion 10, The fire hydrant is disposed so as to protrude from the plate 30.

The fire hydrant according to the present embodiment is provided with the case 14 surrounding the outflow pipe 50 and the stopper member 16 surrounding the outflow port 54 formed in the upper portion of the outflow / It is possible to prevent the protruding and contracting pipe 50 from being deformed or damaged.

Since the check valve is provided in the distribution valve 76 of this embodiment, the operating pressure provided from the pressure tank 72 is supplied to the plurality of cylinders through the distribution valve 76, so that the operating pressure inside the cylinder is low It is possible to prevent the fire hydrant from descending to the inside of the space portion 10 during the fire fighting operation.

After the fire-fighting operation is completed, a release valve for discharging operating pressure from a plurality of cylinders is opened to allow a plurality of rods to be inserted into the respective cylinders, and the pressure tank 72 ), So that the following fire-fighting work can be carried out.

The switch portion 80 includes a knob 82 exposed to the ground, an extension portion 86 extending from the knob 82 to the underground and having a first inclined surface 87, And a pressing block 88 for turning the direction of the operating force pressing the ignition plug 74 to operate.

The knob 82 is provided with a rectangular box made of a safety glass 84 at a position where one of the sidewalk blocks 17 is installed and a knob 82 is installed inside the safety glass 84 The operator can use the tool such as an ax to break the safety glass 84 and to expose the knob 82 to the ground when a fire is generated in the vicinity and a fire hydrant is required.

When the operator presses the knob 82, the extension bar 86 extending downward from the knob 82 is moved downward and the first inclined face 87 formed at the lower end of the extension bar 86 is pressed against the push block 88 While pushing the second inclined surface 88a, the pressing block 88 is moved toward the spark plug 74 side.

The pressing block 88 is provided so as to be slidable in the lateral direction in the horizontal hole portion opposed to the spark plug 74 and the second inclined surface 87 opposed to the first inclined surface 87 is formed at the inner end portion of the pressing block 88. [ And a locking projection 88b is formed at the center of the pressing block 88 so as to protrude in the vertical direction.

Since the elastic member 88c is interposed between the engaging projection 88b of the pressing block 88 and the stepped portion of the hole portion so that the pressing block 88 provides an elastic force for pressing the pressing block 88 in the direction of the extension base 86, The push block 88 pushes up the extension bar 86 to keep the knob 82 in a protruded state.

Reference numeral 52 denotes a stopper 52 formed by bending the lower end of the projecting / retracting pipe 50 inward.

Thus, a fire-fighting outdoor fire hydrant, which is housed in a basement so as to prevent a collision with a pedestrian or a vehicle to prevent a breakdown, and which can protrude to the ground when a worker operates the switch portion when a fire occurs, .
