Description

Apparatus for extinguishing forest fire by the water tank hanging down from the helicopter}

The present invention relates to a forest fire extinguishing apparatus using a helicopter, and includes a water tank, a pumping pump, and a pumping pipe, and a water valve having a plurality of waterproof holes on the bottom of the water tank, and the opening degree of each waterproof hole being adjustable. By installing the pumping pump and pumping pipe, the water tank is used for fresh water and the fire is moved to the forest fire area to control the opening of the waterproof valve to optimize the waterproofing of the fire water according to the progress of the forest fire. The present invention relates to a spray type fire extinguishing device using a helicopter that can perform a more efficient and rapid forest fire extinguishing.

Forest fire extinguishing device using a conventional helicopter is as follows.

first. As shown in the figure (1), the bucket is hung on the helicopter by rope, etc., so that the fire water in the river or lake, etc. can be immersed in the bucket to fly to the forest fire area, and then the opening / closing opening and closing plate installed to open on both sides of the bottom of the bucket is opened. So that there is a waterproof water to digest the bucket.

Figure (1)

In order to effectively extinguish a forest fire, it is desirable to appropriately adjust the amount of waterproof water per hour and the fresh water of fire fighting water according to the progress of the forest fire.

In other words, when extinguishing a large fire with a large flame, it is desirable to increase the waterproof amount per hour and narrow the waterproof area.When extinguishing a small fire or a small flame in the early stage of ignition, the waterproof amount per hour is reduced and the waterproof area is increased. It is preferable.

However, such a conventional device has a narrow horizontal and waterproof width in the direction of flight of the helicopter since the fire extinguishing water contained in the bucket is temporarily waterproofed like a waterfall when the opening / closing plate provided at the bottom of the bucket is opened. Because of being waterproof, there is a problem that does not effectively perform forest fire extinguishing.

That is, in the conventional apparatus, since the hourly waterproof amount or the waterproof area cannot be adjusted when waterproofing the fire water in the bucket, regardless of the initial ignition, the big fire, and the remaining light, both the waterproof amount and the waterproof area per hour become the same. There is a problem that does not perform effectively.

In addition, in order to flush fire water into the bucket, the bucket must be completely submerged in rivers or lakes, so fresh water can be made in rivers or lakes that are deeper than the height of the bucket, but there are only puddles of water that are shallower than the height of the bucket. There is no fresh water in fire fighting water.

Therefore, if there are no rivers or lakes that are deeper than the height of the bucket adjacent to the forest fire area, they should move to the river or lake with the appropriate depth and fresh water, and then move to the forest fire area to waterproof fire water. There is a problem that can not be carried out.

Second, as shown in the figure (2), the helicopter itself has a water tank and a pumping pump, so that the water for extinguishing water in a river or a lake is immersed in the water tank by a pump and then moved to a forest fire area and then on the bottom of the water tank. By opening the opening and closing plate that is installed to open to both sides, there is one to ensure that the fire extinguishing water in the bucket is waterproof.

Figure (2)

However, such a conventional device is capable of fresh water by a pump pump even in shallow water puddles. However, if there are obstacles such as trees around, the descent of the helicopter is practically impossible, so that the risk is not accompanied, and therefore, fresh water is impossible. Even if fresh water is available, the opening / closing type waterproofing system is open and closed, so the waterproofing area of the water per hour and the fresh water in the water tank is constant regardless of the degree of forest fire. do.

Third, as shown in Figure (3), the helicopter itself has a water tank, a pumping pump, and a fresh water / water pipe, so that fire water in rivers or lakes can be immersed in a water tank by a pump and fresh water / water pipe. It is used to waterproof through fresh water / waterproof pipe after flight movement.

Figure (3)

In such a conventional apparatus, fresh water is possible even in shallow water puddles and the like, but there is a problem in that forest fire extinguishing cannot be effectively performed because the waterproof area is very narrow. In other words, if there are obstacles, such as trees, the descent of the helicopter is practically impossible, and therefore, the danger is not followed, and therefore, fresh water is impossible. Even if fresh water is available, the opening / closing type waterproofing system is open and closed, so the waterproofing area of the water per hour and the fresh water in the water tank is constant regardless of the degree of forest fire. do.

Therefore, the object of the present invention can be adjusted according to the progress of the forest fire, and the fresh water regardless of the depth of the water source can be properly adjusted according to the progress of the forest fire and the amount of waterproof water per hour and the waterproof water in the water tank to move from fresh water to forest fire area The aim is to provide a forest fire extinguishing device using a helicopter that can reduce the time to perform forest fire extinguishing effectively and quickly.

The forest fire extinguishing device using the helicopter of the present invention can be waterproofed by opening a plurality of waterproof valves installed in a plurality of waterproof holes drilled in the bottom plate of the water tank in a spray type, so that it can be waterproof in a wide waterproof width in the horizontal direction. This will enable effective forest fire extinguishing.

The forest fire extinguishing device using the helicopter of the present invention can extinguish a fire over a larger area by reducing the amount of waterproofing by reducing the opening degree of the waterproof valve smaller than the maximum opening when extinguishing the small fire or the remaining fire of the initial stage of the fire ignition. Will be.

When the fire extinguishing device using the helicopter of the present invention extinguishes a large fire in which a large flame occurs, it is possible to intensively extinguish a large fire area by maximizing the amount of waterproofing by maximizing the opening degree of the waterproof valve.

In addition, the forest fire extinguishing device using the helicopter of the present invention can use the pumping pump and pumping hose to dehydrate the fire water in the water tank, so that the water can be dehydrated in a deep river or hose as well as a shallow water puddle. Therefore, it is possible to easily secure fire extinguishing water in the vicinity of the forest fire area, it is possible to perform a rapid forest fire extinguishing.
