Oscillating Elevated Monitor for Fire-Fighting}

The present invention relates to an oscillating elevated monitor for fire extinguishing, and more particularly, has a structure capable of reciprocating rotation and change of spray type by the water pressure of fire extinguishing water, and is designed to be able to go up and down in the vertical direction, so that each fire zone It relates to an oscillating elevated monitor for fire suppression capable of suppressing fire according to its characteristics.

In general, when a fire breaks out in a ship, refinery, petrochemical plant, etc. that handles crude oil, gas, chemicals, etc., it not only causes enormous human and material damage, but also causes leakage of crude oil, gas, chemicals, etc. to the environment. It also causes pollution and destruction of ecosystems.

In order to minimize the damage caused by such fires, ships handling crude oil, gas, chemicals, etc., oil refineries, petrochemical plants, etc. are equipped with fire suppression devices to enable rapid suppression in the initial stage of fire occurrence.

Among these fire suppression devices, there is a fire extinguishing monitor that sprays an extinguishing agent such as water (extinguishing water) or foam.

A fire extinguishing monitor is mainly connected to a fixed pipe or hose, and is a type of fire extinguishing agent that discharges a large amount of fire extinguishing agent by aiming at the fire area by adjusting the discharge angle of a fixed nozzle. It is also called a water cannon or water cannon. .

Fire extinguishing monitors are largely divided into manual and automatic types according to the operation method. Manual types include lever-operated and gear-operated types, and automatic types include hydraulic, pneumatic, hydraulic, and electric oscillating monitors. .

U.S. Patent No. 5,791,565 (Hydrostatic bearing for monitors) and U.S. Patent No. 6,305,620 (Firefighting monitor apparatus) disclose technology related to passive monitors. Since the direction of spraying must be controlled by rotating the fire extinguishing monitor in the left and right directions, it is difficult to apply to fire sites where human access is difficult.

On the other hand, the automatic fire extinguishing monitor is an unmanned waterproofing device developed to overcome the problems of the manual fire extinguishing monitor. In particular, by implementing a structure in which an oscillating device is provided to reciprocate and rotate the injection port, a wide range of fire suppression is possible.

Korean Patent Publication No. 10-2020-0098090 discloses an oscillating monitor for fire extinguishing capable of suppressing fire according to the characteristics of each fire zone by having a structure capable of reciprocating rotation and changing the spray shape by the water pressure of fire extinguishing water. Since the height at which fire extinguishing water is sprayed cannot be adjusted, there is a disadvantage in that it is difficult to extinguish a fire that occurs at a higher place than the fire extinguishing monitor or a fire that occurs at a distance from the fire extinguishing monitor.

1 is a perspective view of an oscillating elevated monitor for fire extinguishing according to a preferred embodiment of the present invention.

As shown in FIG. 1, the oscillating elevated monitor for fire extinguishing largely includes a monitor unit 100, a nozzle unit 200, an oscillating unit 300, a multi-stage lift unit 400, and an expansion joint 500. include

The monitor unit 100 has a pipe shape and constitutes the body of the oscillating elevated monitor for fire extinguishing. Preferably, the monitor unit 100 is formed by interconnecting a plurality of pipes by bolting or welding. The lower part is connected to a fire extinguishing water supply line through which fire extinguishing water is supplied by the expansion joint pipe 500 to be described later, and in the event of a fire, a flow path so that the fire extinguishing water flows into the monitor unit 100 to suppress the fire. A supply pipe 110 providing is installed.

At this time, the fire extinguishing water is a kind of fire extinguishing agent used for fire suppression, and may be used as a substitute for other fire extinguishing agents such as fresh water, sea water, and foam fire extinguishing agents.

The fire extinguishing water introduced into the monitor unit 100 is sprayed by the nozzle unit 200 installed above the monitor unit 100 .

The nozzle unit 200 is provided with a spray control unit inside to change the spray type in consideration of the distance from the fire area and the characteristics of the fire area, and a more detailed description will be described later.

Meanwhile, in order to supply fire extinguishing water to the monitor unit 100, as mentioned above, the supply pipe 110 should be connected to the fire extinguishing water supply line.

However, when the supply pipe 110 is directly connected to the fire extinguishing water supply line, separation between the supply pipe 110 and the fire extinguishing water supply line due to the elevation of the multi-stage lifting unit 400 or damage to the interconnection part, etc. Since this may occur, in order to prevent this, one or more expansion joints 500 capable of extending in the longitudinal direction are installed between the supply pipe 110 and the fire extinguishing water supply line.

In other words, the supply pipe 110 is connected to the fire extinguishing water supply line through the expansion joint pipe 500, and through this, the expansion joint pipe 500 increases the height of the multi-stage elevation part 400. It is possible to prevent separation and damage to the connection portion of the supply pipe 110 and the fire extinguishing water supply line by being extended or contracted in the longitudinal direction corresponding to.

In addition, the switching member 238 has an elastic member 239 on an outer circumferential surface corresponding between the locking step 222 and the step 238-2 to elastically support the switching member 238. .

On the other hand, one end of the fixing member 236 is fixed on the inner surface of the nozzle unit 200, and the other end is attached to the sliding groove 234-2 long-indented in the lower outer periphery of the support shaft 234 in the longitudinal direction. Since it is inserted, the upward movement range of the baffle head 232 can be limited.

In other words, the nozzle unit 200 can change the spray form of the fire extinguishing water by the spray control unit, and the spray hole 233 of the baffle head 232 and the spray of the support shaft 234 Through the hole 234-1, not only can the fire extinguishing water be intensively sprayed, that is, jet sprayed, but in particular, the fire zone is adjacent to the place where the oscillating monitor for fire extinguishing is installed or within the fire range. When is wide, the switching member 238 is operated to change the position of the baffle head 232 so that the fire extinguishing water can be sprayed radially, that is, sprayed.
