Description

Oscillating monitor for fire-fighting

The present invention relates to an oscillating monitor for fire extinguishing, and more particularly, by having a structure capable of reciprocating rotation and injection form conversion by the water pressure of fire extinguishing water, thereby improving fire extinguishing efficiency to enable fire suppression according to the characteristics of each fire zone. It relates to an oscillating monitor.

In general, if a fire occurs in ships, refineries, petrochemical plants, etc. that handle crude oil, gas, chemicals, etc., it will cause enormous human and material damage, as well as the environment due to the outflow of crude oil, gas, chemicals, etc. Pollution and ecosystem destruction are also caused.

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

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

Fire extinguishing monitors are mainly connected to fixed pipes or hoses, and are a type of extinguishing agent discharged in large quantities by aiming at the fire area by adjusting the discharge angle of the nozzle at which the position is fixed, and is often called a waterproof gun or water cannon. .

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

U.S. Patent No. 5,791,565 (Hydrostatic bearing for monitors) and U.S. Patent No. 6,305,620 (Firefighting monitor apparatus) have known techniques for manual monitoring, but in the case of manual method, firefighters are required to extinguish fires. There is a disadvantage in that it is difficult to apply to fire sites where human access is difficult because the spray direction must be controlled by rotating the fire extinguishing monitor in the left and right directions.

On the other hand, the automatic fire extinguishing monitor is an unmanned waterproof device developed to overcome the problems of the manual fire extinguishing monitor, and is manufactured to enable automatic driving for application to fire sites where human access for fire extinguishing work is difficult. , In particular, by implementing a structure in which an oscillating device is provided to reciprocate the injection port, a wide range of fire suppression is possible.
