Oscillating Elevated Fire Extinguishing Monitor for Port Crane}

The present invention relates to an oscillating elevated fire extinguishing monitor for port cranes. More specifically, it is attached to a container crane that unloads containers installed at a container-only pier, and immediately detects a fire that occurs on a ship during berthing or unloading or while operating in coastal waters. This is about the oscillating elevated fire extinguishing monitor for port cranes, which is an elliptical fire extinguishing equipment that allows response and suppression.

In general, if a fire occurs in a ship, oil refinery, or petrochemical plant that handles crude oil, gas, or chemicals, it not only causes enormous human and material damage, but also causes environmental damage due to the leakage of crude oil, gas, and chemicals. It also causes pollution and destruction of the ecosystem.

In order to minimize damage from such fires, ships, oil refineries, and petrochemical plants that handle crude oil, gas, and chemicals are equipped with fire suppression devices to enable rapid suppression in the early stages of a fire.

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

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

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

U.S. Patent No. 5,791,565 (Hydrostatic bearing for monitors) and U.S. Patent No. 6,305,620 (Firefighting monitor apparatus) have disclosed technology related to manual monitors. However, in the case of the manual method, firefighters are required to extinguish fires. Since the spray direction must be controlled by directly rotating the fire extinguishing monitor to the left and right, it has the disadvantage of being difficult to apply to fire sites where human access is difficult.

Meanwhile, the automatic fire extinguishing monitor is an unmanned waterproof device developed to overcome the problems of the manual fire extinguishing monitor. It is manufactured to enable automatic operation for application to fire sites where it is difficult to access manpower for fire extinguishing work. , In particular, by implementing a structure in which the nozzle is rotated back and forth by providing an oscillating device, a wide range of fire suppression is possible.

Korean Patent Publication No. 10-2020-0098090 has announced an oscillating monitor for fire extinguishing that is capable of extinguishing fires according to the characteristics of each fire zone by having a structure capable of reciprocating rotation and spraying type conversion by the hydraulic pressure of fire extinguishing water. Since the height at which the fire extinguishing water is sprayed cannot be adjusted, there is a disadvantage in that it is difficult to extinguish a fire that occurs higher than the fire extinguishing monitor or a fire that occurs at a long distance from the fire extinguishing monitor.

U.S. Patent Publication No. 5,791,565 (1998.08.11) U.S. Patent Publication No. 6,305,620 (October 23, 2001) Korean Patent Publication No. 10-2020-0098090 (2020.08.20.)

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

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

As shown in Figure 1, the oscillating elevated fire extinguishing monitor for port cranes largely consists of a monitor unit 100, a nozzle unit 200, an oscillating unit 300, a multi-stage elevation unit 400, and an expansion joint 500. ), a fire water supply pipe 700, and a docking unit unit 720.

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

At this time, the fire extinguishing water is a type of fire extinguishing agent used for fire suppression, and can be used in place of other fire extinguishing agents such as fresh water, sea water, and foam fire extinguishing agent.

The fire extinguishing water flowing into the monitor unit 100 is sprayed by the nozzle unit 200 installed on the upper part of the monitor unit 100.

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

Meanwhile, an oscillating unit 300 is provided on one side of the monitor unit 100 to reciprocate and rotate the monitor unit 100.

Preferably, the oscillating unit 300 is fixedly installed on one side of the outer periphery of the supply pipe 110, and is provided with an induction pipe 320 in communication with the supply pipe 110 to discharge the fire extinguishing water from the supply pipe 110. After receiving a portion of the fire extinguishing water to generate rotational power, the monitor unit 100 can be rotated back and forth using the rotational power.

At this time, the oscillating unit 300 is provided with a power transmission unit 340 to transmit the rotational power to the lower part of the monitor unit 100, thereby enabling the monitor unit 100 to rotate horizontally.

Next, the lower part of the monitor unit 100 is raised or lowered in the vertical direction and the height of the monitor unit 100 is adjusted so that the fire extinguishing oscillating elevated monitor can spray the fire extinguishing water from a high place. A multi-stage lifting unit 400 is formed.

The multi-stage lifting part 400 is provided with a lifting body part 410 formed by sequentially inserting a plurality of lifting bodies, and a lifting wire 430 is connected to the lifting body part 410 to connect the lifting wire 430. As the lifting body is pulled out or retracted by winding or unwinding, the lifting body part 410 expands and contracts in a multi-stage structure to raise or lower the monitor part 100 to adjust the height from one side of the crane 600. .

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

However, when the supply pipe 110 is directly connected to the fire water supply line, the supply pipe 110 and the fire water supply line may be separated or damaged at the interconnection portion due to the raising and lowering of the multi-stage lifting unit 400. Since this may occur, in order to prevent this, one or more expansion joint pipes 500 that can expand in the longitudinal direction are installed between the supply pipe 110 and the fire water supply line.

In other words, the supply pipe 110 is connected to the fire water supply line via the expansion joint 500, and through this, the expansion joint 500 is raised and lowered at the height of the multi-stage lifting unit 400. By expanding or contracting in the longitudinal direction in response, separation and damage to the connection portion of the supply pipe 110 and the fire water supply line can be prevented.

At this time, the expansion joint 500 may be formed of a bellows-type expansion joint, a sleeve-type expansion joint, a loop-type expansion joint, etc., but is not limited thereto and is formed of various types of pipes that can be expanded and contracted in the longitudinal direction. Of course it can be done.

You can.

Therefore, since the hydraulic pressure of the fire water supplied to the nozzle unit 200 acts on the lower surface of the baffle head 232, when the worker grasps the handle 238-1 of the switching member 238 and pulls it in one direction, , As the other end of the switching member 238 comes out of the fixing groove 234-3, the baffle head 232 moves upward due to the water pressure of the fire extinguishing water, as shown in FIG. 3, A portion of the seat portion 210 may be opened to provide a passage through which the fire extinguishing water is sprayed radially.

Here, the plurality of fixing grooves 234-3 are spaced apart from each other at a predetermined interval.

In addition, a locking protrusion 222 protruding along the circumference is formed on the inner peripheral surface of the through hole 220, and a step 238-2 protruding outward is formed on the outer peripheral surface of the switching member 238 to form the handle 238-2. Even if 1) is held and pulled in one direction, the switching member 238 is prevented from being separated from the nozzle unit 200.

In addition, the switching member 238 is provided with a first elastic member 239 on the outer peripheral surface corresponding to between the stopping protrusion 222 and the step 238-2 to elastically support the switching member 238. Let's do it.

Meanwhile, 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 a sliding groove 234-2 formed long in the longitudinal direction on the lower outer periphery of the support shaft 234. Since it is inserted, the upward movement range of the baffle head 232 can be limited.

In summary, the nozzle unit 200 is capable of changing the spray form of the fire water by the spray control unit, and the spray port 233 of the baffle head 232 and the spray of the support shaft 234 Not only can the fire extinguishing water be intensively sprayed through the hole 234-1, that is, jet sprayed, but in particular, the fire zone is adjacent to the place where the fire oscillating monitor for fire extinguishing is installed or is 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 is sprayed radially, that is, sprayed.

FIG. 4 is a cross-sectional view showing another embodiment of the nozzle portion shown in FIG. 1.

As shown in FIG. 4, even in a state where the upper opening of the nozzle unit 200 is closed by the baffle head 232, the fire extinguishing agent is sprayed finely through the injection hole 233. A plurality of first injection holes 233-1 may be formed, and a plurality of second injection holes 234-1a may be formed on the support shaft 234.
