Embodiment Construction

[0027] Embodiment of the invention

[0028] Preferred embodiments of the present invention are shown below. In the following embodiments, the fire extinguishing object is the charging system of the sodium-sulfur battery, figure 1 is the front view of the charging system for a sodium-sulfur battery, figure 2 is a longitudinal section view, image 3 It is a perspective view of a battery module.

[0029] In these figures, 1 is a battery module, and as described above, the battery module 1 is a member that accommodates a plurality of sodium-sulfur single cells inside a heat insulating container. A charging system for a sodium-sulfur battery is configured by combining a plurality of such battery modules 1 according to the charging capacity. Each of these battery modules 1 is a rectangular parallelepiped with a width and depth of approximately 2 m and a height of approximately 1 m, and is accommodated in a multi-layered manner inside a rack 2 whose entire height is approximatel...

Abstract

The present invention pertains to a feature for extinguishing fire by using gas pressure to discharge fire-extinguishing sand onto the upper surface of an object to be fire-extinguished, such as a battery stored among other batteries on a rack. The present invention involves providing a deflector plate (16) in the tip section of a flat nozzle body (12), and uniformly dispersing the fire-extinguishing sand on an entire upper-surface by spraying the same in a downward-diagonal direction and causing the same to bounce.

Description

technical field [0001] The present invention relates to a fire extinguishing nozzle suitable for extinguishing a fire extinguishing object having a flat upper space such as a battery module case accommodating an assembled battery, and a fire extinguishing method using the same. Background technique [0002] A charging system using an assembled battery is constituted by combining a plurality of battery modules in which hundreds of single cells are housed in a heat-insulated container. These battery modules are housed inside the rack in multiple layers. For example, when five layers are usually stacked, the height from the bottom surface (ground) to the uppermost layer is approximately 5 m. And in order to reduce the installation space as much as possible, the height of each layer of the rack is set to be only slightly larger than the height of the battery module, so the height of the upper space of the battery module is only about a few centimeters. However, the upper space ...
