Abstract

Provided is a dropping-type fire extinguishing body that, in fire extinguishing using a gel-like fire extinguishing agent, can allow the fire extinguishing agent to be smoothly conveyed and dropped.
A dropping-type fire extinguishing body 1 to be dropped onto the fire site to extinguish the fire, wherein a gelling agent 3 is contained in a bag body 2 formed of a water-permeable material and water is permeated into the body and is mixed with the gelling agent to prepare a gel-like fire extinguishing agent, thereby filling the gel-like fire extinguishing agent into the inside of the bag body.

First claim

The invention claimed is:

1. A dropping-type fire extinguishing body to be dropped on a fire site for extinguishing the fire, wherein the dropping-type fire extinguishing body comprises a bag body formed of a water-permeable material which stores a gel-like fire extinguishing agent, and the gel-like fire extinguishing agent is formed by allowing water to be permeated into the bag body and to be absorbed in a gelling agent stored therein, whereby the inside of the bag body is filled with the gel-like fire extinguishing agent, and wherein the bag body is formed of a low impact-resistant material.

2. The dropping-type fire extinguishing body according to claim 1 , wherein the bag body is formed of a material that is easily melted by heat.

3. The dropping-type fire extinguishing body according to claim 1 , wherein the bag body further contains surfactant agent.

4. The dropping-type fire extinguishing body according to claim 1 , wherein the bag body, when filled with the gel-like fire extinguishing agent through permeation of water, has an outer shape of a triangular pyramid shape or a spherical shape or a cubic shape.

5. The dropping-type fire extinguishing body according to claim 1 , wherein the gelling agent is an edible gelling agent selected from gelatin, carrageenan, agar, and polysaccharides.

6. A gelling agent-storage bag body for the manufacture of a dropping-type fire extinguishing body according to claim 1 , the gelling agent-storage bag body comprising:
the gelling agent; and
the bag body formed of the water-permeable material and containing the gelling agent.

7. A dropping-type fire extinguishing body dropping apparatus, the apparatus comprising:
a gelling agent storage body according to claim 6 loaded thereon,

wherein the apparatus is configured to be brought into a position above a fire site and is configured to allow the dropping-type fire extinguishing body to be dropped on the fire site.

8. An aircraft loaded with a dropping-type fire extinguishing body dropping apparatus according to claim 7 .

9. A dropping-type fire extinguishing body dropping apparatus, the apparatus comprising:
a dropping-type fire extinguishing body according to claim 1 loaded thereon, wherein the apparatus is configured to be brought into a position above a fire site and is configure to allow the dropping-type fire extinguishing body to be dropped on the fire site.

10. An aircraft loaded with a dropping-type fire extinguishing body dropping apparatus according to claim 9 .

11. A fire extinguishing method comprising:
using an aircraft according to claim 10 ;
mixing the gelling agent with water within the aircraft during movement to a fire site to form the dropping-type fire extinguishing body;
loading the dropping-type fire extinguishing body on the dropping-type fire extinguishing body dropping apparatus; and
when the aircraft arrives at a position above the fire site, dropping the dropping-type fire extinguishing body on a fire by the dropping-type fire extinguishing body dropping apparatus.

12. The fire extinguishing method according to claim 11 , wherein the dropping-type fire extinguishing body is dropped while predicting an optimal position for dropping of the dropping-type fire extinguishing body to a fire site with a high accuracy by acquiring data on the shape and weight of the dropping-type fire extinguishing body, information on wind direction and speed and information on fire position of a fire site, information on position, altitude, course, and speed of the aircraft and calculating an optimal dropping position of the dropping-type fire extinguishing body.

13. A fire extinguishing method comprising:
using an aircraft according to claim 10 ;
loading a dropping-type fire extinguishing body dropping apparatus on which the dropping-type fire extinguishing body has been preloaded, on the aircraft when the aircraft flies to a fire site; and
when the aircraft arrives at a position above the fire site, dropping the dropping-type fire extinguishing body on a fire site by the dropping-type fire extinguishing body dropping apparatus.

14. The fire extinguishing method according to claim 13 , wherein the dropping-type fire extinguishing body is dropped while predicting an optimal position for dropping of the dropping-type fire extinguishing body to a fire site with a high accuracy by acquiring data on the shape and weight of the dropping-type fire extinguishing body, information on wind direction and speed and information on fire position of a fire site, information on position, altitude, course, and speed of the aircraft and calculating an optimal dropping position of the dropping-type fire extinguishing body.

15. A method for manufacturing a dropping-type fire extinguishing body, the method comprising:
providing a bag body formed of a water-permeable material and a low impact-resistant material, the bag body containing a gelling agent; and
allowing water to permeate into the bag body and to be mixed with the gelling agent to prepare a gel-like fire extinguishing agent, thereby filling the gel-like fire extinguishing agent into the bag body.

16. A dropping-type fire extinguishing body to be dropped on a fire site for extinguishing the fire, wherein the dropping-type fire extinguishing body comprises a bag body formed of a water-permeable material which stores a gel-like fire extinguishing agent, and the gel-like fire extinguishing agent is formed by allowing water to be permeated into the bag body and to be absorbed in a gelling agent stored therein, whereby the inside of the bag body is filled with the gel-like fire extinguishing agent, and wherein the bag body has a low impact-resistant joined portion.

17. A dropping-type fire extinguishing body to be dropped on a fire site for extinguishing the fire, wherein the dropping-type fire extinguishing body comprises a bag body formed of a material that is water-permeable and which stores a gel-like fire extinguishing agent, and the gel-like fire extinguishing agent is formed by allowing water to be permeated into the bag body and to be absorbed in a gelling agent stored therein, whereby the inside of the bag body is filled with the gel-like fire extinguishing agent, and wherein the material of the bag body contains polylactic acid.

18. The dropping-type fire extinguishing body according to claim 17 , wherein the content of the polylactic acid is not less than 80% by mass.

19. The dropping-type fire extinguishing body according to claim 17 , wherein the basis weight of the polylactic acid is 10 to 30 g/m 2 .
