Description

Day and night forest fire extinguishing device using helicopter {Apparatus for extinguishing forest fire by the water tank hanging down from the helicopter}

The present invention relates to a day and night forest fire extinguishing device using a helicopter, and more particularly, having a water tank, a pumping pump, and a pumping pipe, and having a plurality of waterproof holes at the bottom of the water tank, and opening and closing each water hole. Install a valve to freshen the fire extinguishing water in the water tank using a pumping pump and pumping pipe, and fly to the forest fire area to optimize the waterproofing of the fire extinguishing water according to the progress of the fire. It relates to a day and night forest fire extinguishing device using a helicopter that can perform forest fire extinguishing.

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

first. As shown in the figure (1) below, the bucket is hung on the helicopter rope, and the fire water in the river or lake is immersed in the bucket and flown to the forest fire area, and the opening and closing plate installed to open on both sides of the bottom of the bucket By opening the water to the fire extinguishing water in the bucket is one.

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. Therefore, fresh water can be used in rivers or lakes that are deeper than the height of the bucket. Desalination of fire water is impossible.

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 following figure (2), the helicopter itself is provided with a water tank and pumping pump, and the extinguishing water in the river or lake is freshwater pumped by the pump to move to the forest fire area, and then the water tank By opening the opening and closing plate to be installed to open to both sides on the lower surface there is a thing that the fire extinguishing water in the bucket is waterproof.

Figure (2)

However, such a conventional device is capable of fresh water by a pumping pump even in shallow water puddles. However, if there are obstacles such as trees in the vicinity, the descent of the helicopter is practically impossible, so the danger is not only followed by fresh water. 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 the following figures (3a) and (3b), the helicopter itself has a water tank, a pumping pump, and a fresh water / water pipe, so that the digestive water in the river or lake is pumped by the pump and the fresh water / water pipe. It is used to waterproof through fresh water / water pipe after flying to wildfire area by fresh water.

Figure (3a)

Figure (3b)

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 descending flight of the helicopter is practically impossible, so that 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, in order to solve the problems as described above, the present invention can be appropriately adjusted according to the progress of the forest fire, and the fresh water regardless of the depth of the water source and the water resistance per hour and the waterproof area of the fire water in the water tank.
