Description

{A stand for a fire hose spray test}

The present invention relates to a fire hose fire-fighting water spray test stand, and more particularly, to a fire hose fire-hose fire-hose fire-fighting fire hose fire- To a pedestal for spraying fire water.

In general, firefighting facilities are facilities that detect when fire occurs, notify the surrounding area, turn off the fire, facilities to secure water necessary for fire fighting, and facilities to help the firefighting team.

In other words, fire fighting equipment, alarm equipment, evacuation equipment, fire fighting water equipment, fire fighting equipment can be organized.

Among the fire extinguishing facilities, the fire hose is a facility for providing a duct for discharging water for fire fighting, and is one of the most important facilities among the fire extinguishers in the apartment house and fire extinguishing facilities connected to the fire trucks.

The fire hose includes a nozzle for controlling the flow rate and water pressure of the injected fire water, and the nozzle is installed at the end of the fire hose.

When a fire occurs, the fire hose is handled by the general public or a firefighter and the fire suppression is made.

In other words, when a fire hydrant is installed in a public housing or a public building, anyone who witnesses the fire operates the fire hydrant and uses the fire hose to spray the fire water to suppress the fire. When the fire hydrant Firefighters use fire hoses installed in fire trucks to conduct fire suppression.

In this case, when the fire is suppressed by using a fire hydrant installed in the building, there is no great problem. However, when the fire is sprayed from the outside of the building in case of a large fire, the fire water is sprayed while controlling the flow rate and water pressure of the fire water very important.

That is, when the fire hose can not reach the ignition point even if the elevated ladder is used, it is important to use the nozzle installed at the end of the fire hose because the fire extinguishing operation must be performed by using the water pressure of the fire water to efficiently fire the fire water.

It is also important to use the fire hose considering the water pressure that is lost when several fire hoses are connected and used.

However, conventionally, there is no test data on the correlation between the water pressure injected by the fire-fighting water and the distance of the fire-fighting water injected, so that the fire suppression depends on the experience of the fire-fighter.

The use of such a conventional fire hose has a problem in that the use efficiency of the fire hose is low when a large fire occurs.

Therefore, in order to solve such a problem, it is necessary to test the correlation between the water pressure of the fire water sprayed from the fire hose and the spray distance of the fire water through the test.

Meanwhile, in order to test the correlation between the water pressure of the fire water and the spray distance, it is necessary to apply the water pressure while applying various water pressure.

In this case, since the water pressure of the fire water is high, several people are holding the fire hose and the fire water is sprayed. In this process, it is difficult to predict the fluctuation of the fire hose according to the water pressure of the fire water.

In other words, a safety accident may occur to a person holding a fire hose by water pressure sprayed by a fire fighter, and when a fire hose is missed, a safety accident may occur to all the people involved in the test due to the fire hose fluctuation It is.

This completes the preparation of fire-fighting water injection through the fire hose.

Thereafter, when the pump is operated to spray the fire water, the fire water passes through the fire hose connection pipe 700 and is injected through the nozzle.

At this time, since the water pressure is measured through the water pressure meter 710 installed in the fire hose connection pipe 700, it is possible to measure the distance through which the water is sprayed according to the water pressure of the water.

In addition, since the correlation of the distance of the fire water spraying distance according to the angle of the nozzle can be grasped, the manual work of the fire hose spraying distance can be easily and accurately performed.

Furthermore, since the waterproofing can be performed unattended, the test can be performed without a safety accident caused by the fire hose grasping.

Meanwhile, the detachment structure of the fixing table 600 can be provided in a simpler structure than a screw connection using the fixing bolts B. [

This is shown as another embodiment of the present invention, and will be described with reference to FIGS. 5 and 6 attached hereto.

The upper fixing table 620 and the lower fixing table 610 are detachably attached to the upper fixing table 620 and the lower fixing table 610 by means of the detachable means 800.

The detachment means 800 includes a hook 810, an insertion hole 820, an access hole 830, a housing 840, a locker 850, a stopper 860, .

The hook 810 serves to constrain the upper fixture 620 to the lower fixture 610 and extends downward from both the bottom sides of the upper fixture 620.

The insertion stud 820 is a passage through which the hook 810 is inserted into the lower fixing table 610 and is formed so as to pass through at a position corresponding to the hook 810.

Next, the entrance and exit study 830 provides a passage through which the locker 850 moves in and out of the lower fixing table 610, and is formed on the side surface of the lower fixing table 610.

Next, the housing 840 has a structure in which the locker 850 is installed, and is formed to have an internal space on a side surface of the lower fixing table 610.

Next, the locker 850 is installed in the housing 840, which serves to restrain the hook 810 inserted through the insertion stud 820 or release the hook 810 that has been restrained.

The locker 850 moves to the inside of the lower fixing table 610 through the access hole 830 formed in the side surface of the lower fixing table 610 and fixes or disengages the hook 810 located inside the lower fixing table 610, .

At this time, the tip end (left side in the drawing) of the locker 850 forms an inclined surface corresponding to the inclined surface of the hook 810, and the locker 850 is formed with a stopper 860 hooked to the entrance and exit 830.

The stopper 860 restricts the locker 850 from being excessively inserted into the lower fixing table 610 and is formed to have a larger diameter than the diameter of the access hole 830.

The locker 850 is elastically supported by the spring S in the housing 840.

At the rear end of the locker 850, a knob 861 positioned outside the housing 840 is formed.

That is, the user can grasp the handle 861 and pull the front end of the locker 850 out of the lower fixing table 610.

At this time, the handle 861 forms a latching hole 861a and can be hinged to the rear end of the locker 850. [

With such a configuration, the handle 861 can be rotated about the hinge and folded toward the side of the housing 840.

On the other hand, a locking ring 841 bent outward from the housing 840 is formed on the side surface of the housing 840.

The latching ring 841 is configured such that the knob 861 folded to the side of the housing 840 can be hooked and fixed.

Desorption operation of the upper fixing table 620 and the lower fixing table 610 by the detachment means 800 having the above-described configuration will be described.

The fire hose connection pipe 700 is seated on the first seating portion 611 in a state where the upper fixing table 620 is separated from the lower fixing table 610.

Next, when the fire hose connection pipe 700 is covered with the upper fixture 620, the hook 810 is automatically lowered through the insertion hole 820.

In this process, the hook 810 pushes the slope of the locker 850 and pushes the locker 850 out of the lower fixture 610 through the entrance / exit 830.

At this time, the locker 850 is retracted while the spring S is retracted. When the hook 810 is further lowered below the locker 850, the spring S is restored and the locker 850 is retracted.

At this time, the locker 850 is positioned above the hook 810 as shown in FIG. 5, and the hook 810 is restrained inside the lower fixture 610.

Thus, the upper fixture 620 is not released from the lower fixture 610.

In order to prevent the locker 850 from being pushed by the water pressure of the fire water even if the locker 850 restrains the hook 810 as described above, the handle 861 And the latching hole 861a is fixed to the latching ring 841 formed on the side surface of the housing 840 by rotation.

This completes the coupling of the upper fixture 620 to the lower fixture 610.

Thereafter, in order to separate the upper fixing table 620 from the lower fixing table 610, the knob 861 is rotated to release the latching hole 861a from the latching hook 841. [

Next, the knob 861 is pulled to release the locker 850 that has been restraining the hook 810.

Thereafter, the upper fixing table 620 is lifted to separate the upper fixing table 620 from the lower fixing table 610, thereby completing the separation process of the upper fixing table 620.

As described above, according to the present invention, there is a technical feature that a pedestal for spraying fire-fighting water spraying test is capable of water-proofing the fire-fighting hose.

Accordingly, it is possible to easily and accurately perform the manual work on the correlation between the water pressure and the spraying distance of the fire hose of the fire hose, and can be effectively used in the field of fire drill and fire fighting.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
