成されている。In the figure, (1) is an insulated container in which cell assemblies (2) consisting of sodium-sulfur cells are arranged and housed. A plug (4) made of a heat insulating material is fitted to the negative side port to make it airtight. Furthermore, inside this insulation/thermal container (1),
As shown in Fig. 2, a hollow and sealed stainless steel fire extinguishing agent spouting body (5) whose internal pressure is maintained at a predetermined value is provided above the cell assembly (2). A plurality of openings (6) are formed in the fire extinguishing agent spouting body (5) and open toward each cell of the cell assembly (2), and each opening (6) is made of aluminum alloy or the like. A sealing body made by combining two types of low melting point metals with different melting points (sealed by force. The two types of low melting point metals are the same and seal the opening (6) as shown in Figure 2. For example, the sealed body (7) having a relatively low melting point of about 400 to 500°C (
7a) and a sealed body (with a melting point of 50 to 100°C higher than this)

It may be arranged so that the part sealed with is in a required positional relationship. In addition to the box shape shown in FIG. 2, the fire extinguishing agent jetting body (5) may also be a pipe type with closed ends and multiple bends as shown in FIG. In this case as well, a similar opening (6) and sealing body (7) may be provided. Furthermore, a heat insulating container (1)
On the outside, a pulp (8

効果を高め短時間で消火できる。(Function) A device configured in this way is normally operated at a high temperature of about 300 to 350°C, similar to conventional high-temperature battery devices, and in this case, the extinguishant jetting body (5) A sealing body (7) made of a low melting point metal closes the opening (6).
) remains in a solid state because it has not reached its melting point, and the inside of the fire extinguishing agent jet (5) is sealed and maintains a pressure value above a predetermined value, but in the unlikely event that a fire occurs. In such a case, the temperature near the point where the accident occurred will rise rapidly, and the sealing body (7) of the opening (6) near the point will heat and melt and open, causing the extinguishing agent jet (5) to open. )
The internal pressure value will drop all at once. At the same time, the gas pressure sensor θ0) sends an abnormality detection signal, and the extinguishing agent (9) automatically supplies the extinguishing agent to the extinguishing agent jetting body (5). As a result, the sealing body (7) melts. The fire extinguishing agent is intensively sprayed from the opened opening (6) toward the cell, which is the point where the accident occurred, and the fire is instantly extinguished. Furthermore, the sealing body is composed of two types of low melting point metals with different melting points, and during the initial extinguishing stage, the lower melting point metal melts open and sprays an appropriate amount of extinguishing agent, but the fire does not stop. If the fire is expanded, the lower melting point metal with a higher melting point will also be melted open and a large amount of fire extinguishing agent will be introduced to increase the fire extinguishing effect and extinguish the fire in a short time.

論である。In this way, in the present invention, extinguishing agent is sprayed intensively only on the cells where a fire accident has occurred, so extinguishing can be carried out extremely efficiently in a short time and with a small amount of extinguishing agent used. It becomes possible. It goes without saying that even if a fire accident occurs not in one place but in multiple places, fire extinguishing can be carried out similarly quickly and efficiently.

できるという利点も有するものである。(Effects of the Invention) As is clear from the above explanation, in the present invention, extinguishing agent can be intensively sprayed only on the cells where an accident has occurred, so extinguishing can be carried out extremely quickly and efficiently. The amount of extinguishing agent used is also minimal and economical.
In particular, when the sealing body is composed of two types of low melting point metals with different melting points, only the low melting point metal with the lower melting point melts and opens during the initial extinguishing stage to spray an appropriate amount of extinguishing agent. If a fire spreads, the metal with a higher melting point melts open and a large amount of extinguishing agent is introduced, increasing the extinguishing effect and extinguishing the fire in a short time.Furthermore, the structure is simple and there is no need for extra fire. Another advantage is that the entire device can be miniaturized without taking up much space.
