Is 60 cm to 1 m long and is mainly used for extinguishing fires in outdoor oil tanks, enclosures, or yard in the yard, it has no remote control or automatic start function, and it weighs 50 to 100 kg and is a barrel nozzle. The operation was a fire extinguisher that artificially operated two handles each in the vertical and horizontal directions to discharge water. The above-mentioned conventional water gun is heavy and tall, so it is suitable for outdoor operation, but it is difficult to operate and move in a narrow area or narrow passage even outdoors. There was a surface that was exposed and was liable to be soiled, which spoiled the appearance.

[0003]

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, the Applicant intends to improve the conventional water gun function. Firstly, the capacity mechanism is a labor-saving mechanism with good operability, and the appearance and dust pollution, Maintenance function to prevent rusting and a compact form that is easy to carry and move. Secondly, even if the mechanical capacity is a mini size, it has effective functions that are not inferior to conventional ones, and aims to expand the range of activities that can be freely moved indoors as well as outdoors.
Thirdly, it was an object of the present invention to provide a water monitor that is not only a manual operation but also an automatic operation, and has a wide-ranging and advanced function by a remote control function in conjunction with fire detection ITV technology. .

[0004]

[Means for Solving the Problems] As means for achieving the above-mentioned object, a base C connected to a water supply unit and a lateral C-shaped ellipse which is mounted on a rotating unit on the base and is capable of a constant wide-angle rotation. -Shaped bifurcated tube and a short nozzle part mounted on both tip tube parts to which the elliptical bifurcated tube is joined via rotary bearings, and the nozzle part vertically orients at an elevation angle, The gist of the invention is that the water discharge is automatically and manually switchable, and that the cover body is attached to the main body of the base and the ITV camera and the remote control device are connected.

[Embodiment]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below.
FIG. 1 is a front view of the compact water discharge fire extinguisher of the present invention, and FIG. 2 is a side view. In the drawings, f is a device main body, 1 is a base, and 1
a is a flange. The flange 1a is the water supply pipe 2 of the water supply unit
As shown in FIG. 4, the motor valve 21 attached to the water supply pipe automatically opens and closes by remote control. 22 is a manual valve. Reference numeral 3 is a bifurcated pipe installed on the base 1, and a horizontal plane rotation of a horizontal starting and rotating part 4 which is branched into bifurcated pipes 3a and 3b from the pipe base and is formed into a horizontal C-shaped elliptical shape and is supported by the pipe base. The gear mechanism makes a turning motion in a wide angle of 300 ° in the horizontal direction. 5 is a horizontal starting worm gear of the horizontal plane rotation gear mechanism, 6 is a worm shaft, 7 is a drive unit, 8
Is the drive shaft. The branched bifurcated pipes 3a and 3b are provided with a nozzle 10 supported through rotary bearings 9 and 9 by bearings attached to the connecting portions of the two tip pipe portions opposite to each other as shown in FIGS. To project. Maximum nozzle size is 1
It is formed with a length of 0 cm and a minimum of 5 cm, which is about 1/10 of the conventional size. As shown in FIG. 2, the nozzle 10 includes a vertically moving gear shaft 12 connected to a driving unit 15 and a vertically moving gear 13 axially attached to the gear shaft 12 so that the nozzle 10 has a dip angle of −80 ° and an elevation angle of 60 °.
It can move up and down a total of 140 °. The structure of the nozzle has a function corresponding to the conventional long barrel nozzle by adjusting the gap of the water discharge adjusting valve 14 attached to the tip using a special structure nozzle, and the volume of the device main body f has a vertical height of 38 cm and a horizontal width. Is 3
It is a 0 cm compact type water spray fire extinguisher. By adjusting the nozzle 10, switching to either straight line (jet) water discharge or diffusion (spray) water discharge by adjustment, the water discharge performance jumps about 30 m at a straight line (jet) distance, and sprays a width of 4 m to 5 m by diffusion (spray). It has a flying distance of 10m. Reference numeral 15 is a water discharge switching drive unit, 16 is a manual handle, 17 is an ITV camera for detecting the ignition point of a fire, 18 is a control box, 19 is a remote control box, and 20 is a cover body attached to the main body f.

[0006]

The compact water discharge fire extinguisher of the present invention has a compact equipment which can be effectively used for indoor water discharge, and includes a bifurcated pipe and a nozzle in the main body cover, and a vertical motor for driving the nozzle up and down. Gears are arranged and a horizontal motor and gears are arranged for horizontal movement, which can be steplessly switched, and switching between a straight line (jet) and diffusion (spray) can also be continuously changed. The main body is equipped with an ITV camera that detects the ignition point, determines the water discharge point, and automatically opens and closes the water discharge valve with an ON / OFF switch. Even if the power is lost, manually open the valve by changing to the ON-OFF switch.
The vertical and horizontal movements of the nozzle are operated by the handle, and when the nozzle moves vertically, the nozzle automatically orients downward when it reaches a dip angle of -15 ° to -80 ° and a dip angle of -15 °.
The water is gradually diffused on the basis of, and the water is designed to be maximum when the dip angle reaches −80 °, and the water discharge pressure at the dip angle is adjusted to be lower than that at the dip angle.

[0007]

As described above, the small water fire extinguisher according to the present invention can be provided as a water fire extinguisher for indoor fire extinguishing, which is equipped with an effective automatic control and a manual device which are excellent in operability, labor saving and functionality as well as maintenance of the main body.
