Description

[0001] Sprinklers for flood prevention device [

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an apparatus for preventing a sprinkler, and more particularly, to an apparatus for preventing a sprinkler against sprinkler.

Generally, a sprinkler is installed in a building and is installed in a ceiling of a room to fire fire in a room when a fire occurs.

Such a sprinkler is capable of evolving fire by spraying water over a wide area within a short time, and has been widely used in factories, offices and apartment houses due to its excellent effect on early evolution.

However, in a factory for manufacturing semiconductors or electronic products using expensive manufacturing equipment, water sprays often occur due to malfunction of the sprinkler in the absence of fire. And water sprayed from the sprinkler by the malfunction causes infiltration into an expensive manufacturing apparatus, thereby causing damage to many property such as failure of the apparatus.

In order to overcome such a problem, there is known a "apparatus for preventing water spillover for an up-and-down spray type spring cooler" (hereinafter referred to as "a conventional sprinkler water spoilage prevention apparatus") of Korean Utility Model Registration No. 0343749.

A conventional flood prevention device is installed on a ceiling or a side wall of a building to block water sprayed due to a malfunction of a sprinkler installed for initial fire evolution in the event of a fire, A drain pipe formed at a lower end thereof with a coupling groove formed to protrude outwardly, a bellows pipe formed at an upper portion thereof, and a transparent window formed at a lower portion thereof; An elastic body in the form of a leaf spring having a fixing protrusion formed at an upper end thereof; A water pan coupled to a rubber plate having a dome shape on an upper surface thereof, a drain hole formed on a bottom surface thereof, and a head insertion hole formed on a central portion thereof; And a PVC water bag installed to communicate with the drain pipe.

However, when the conventional sprinkler preventing apparatus for a sprinkler configured as described above is used, the following problems arise.

First, the height of the ceiling of a room in a semiconductor manufacturing factory is maintained at a high height of about 6 to 9 m. Therefore, when the conventional flotation prevention device is used, the length of the drain pipe should be about 6 to 9 m. However, since the drain pipe constituting the conventional flood prevention device is composed of a metal or a synthetic vertical pipe, when the length is made long, the flood prevention device has a heavy own weight, which makes it difficult for the user to carry it.

In addition, since the flood prevention apparatus having a long drain pipe is bulky and difficult to store in a factory, it has a problem that it can not be quickly coped with malfunction of the sprinkler.

Further, when the drain pipe constituting the conventional flood prevention apparatus is made as long as 6 m to 9 m, the strength of the drain pipe is weak, and the drain pipe is bent and broken during use.
