Tarpaulin holder for fire hoses {Holder of Water Cannon for Fire Hose}

The present invention relates to a tarpaulin holder for a fire hose, and more specifically, when a fire hose is sprayed with a fire hose connected to a fire engine or a fire hose connected to a fire suppression facility around a fire generating place, it is provided at the end of the fire hose. The present invention relates to a tarpaulin holder for a fire hose, which enables the sprayer to spray the fire fighting water to continuously spray the fire fighting water to the point where the fire occurred without manpower.

In general, in the event of a fire, the fire hose of the fire truck or fire extinguishing equipment provided in the vicinity of the fire engine is promptly moved to the fire place, and then a tarpaulin is installed at the end of the fire hose to spray fire water into the fire place. Will be suppressed.

At this time, there is a case where it is necessary to continuously spray the fire fighting water toward the same point of the fire place, and it is impossible to grip the fire fighting hose and tarpaulin for a long time due to severe fatigue in the spraying pressure of the fire fighting water. If you do not continue to grasp, or if there is a risk of explosion, you will not be close to the fire.

In this case, by mounting the tarpaulin for the fire hose using a cradle, it is possible to continuously extinguish the fire water by spraying it into the fire place without manpower.

As a prior art of the cradle, a manned or unmanned waterproof rod for mounting a fire hose is known in Korean Registered Room 20-0436120.

The prior art adjusts the semi-cylindrical cradle 6 and the fixing band 9 and the semi-cylindrical cradle 6 to fix the fire hose A and the nozzle B without shaking as shown in FIG. 1. According to the handle 11 and the "U" shaped yoke 5 to fix the left and right movements of the semi-cylindrical cradle 6 and move only in the upper and lower directions, and according to the vertical movement of the semi-cylindrical cradle 6 A circular pin 7 with a fixed position changing, a bolt 8 selectively fixing the circular pin 7, and fixing the up and down movement of the "U" shaped yoke 5 and moving only the left and right directions A 360 degree rotating tripod head 3, a bolt 4 for selectively fixing the direction of the rotating tripod head 3, a tripod 1 supporting the tripod rotating head 3 on the ground, The wire 13 and the turnbuckle 14 for fixing and adjusting the angle of the tripod 1 leg and the wire 13 at the center of the tripod 1 are supported. The third circular hole is composed of rings (2).

According to the prior art having such a configuration, the fire hoses (A) and nozzles (B) branched from indoor and outdoor fire hydrants are fixed and mounted on the semi-cylindrical cradle (6), thereby allowing self-adjusting waterproofing up, down, left, and right. And, compared to holding the fire hose (A) and the nozzle (B) directly and waterproofing, there is an effect that does not require significant manpower or power.

In addition, since the up, down, left, and right movements of the semi-cylindrical cradle 6 can be fixed by using the circular pins 7 and bolts 8, the nozzle direction is fixed in the fire zone in a danger area such as an explosion. Evacuation and safety can be met at the same time, and the angle of the tripod (1) can be adjusted according to the user, and the semi-cylindrical base (6) and the tripod (1) can be folded, which means that It has the effect of being placed in a fire hydrant.
