Description

Heat Collecting Plate Fixing Device for Sprinkler}

The present invention relates to a heat collecting plate fixing device for firefighting equipment, and more particularly, to a heat collecting plate fixing device for firefighting equipment that can be fixed by simply, conveniently and safely combining a heat collecting plate or a shielding plate to a sprinkler that is a firefighting equipment.

A sprinkler is an initial extinguishing of a fire using fire water when a fire occurs, and a sprinkler activates an automatic fire extinguishing and alarm system when the indoor temperature exceeds a certain temperature (for example, 70℃ or higher) to prevent an accident. Can be prevented. Therefore, it is mandatory to install it in apartments and houses as well as buildings where many people are concentrated such as department stores, hotels, and hospitals.

The sprinkler is installed on a structure or indoor ceiling spaced apart from the floor of a building, and the separation distance from the ceiling surface and installation method are stipulated in the rules related to fire fighting technology or fire fighting regulations.

Here, the head of the sprinkler coupled to the pipe connected to the fire extinguishing water has a heat-sensing part that senses heat, and the heat-sensing part detects heat due to fire, etc. The pump is activated to supply extinguishing water to extinguish the fire.

However, when sprinkler piping is installed in a building with a high ceiling such as a warehouse or factory, if the distance between the ceiling and the location where the sprinkler piping is installed is wide, the heat flow of the fire passes through the sprinkler piping and rises to the ceiling, and the heat sensing unit of the sprinkler takes time to detect the heat. It takes. There is a high concern that it will not be possible to extinguish the fire at the initial stage because it takes time for the heat sensor to detect heat. Therefore, it is preferable to provide a heat collecting device or a'heat collecting plate' so that heat can be quickly detected in the sprinkler pipe part.

In addition, this heat collecting device not only collects heat, but also prevents delaying the reaction of the sprinkler pipe due to fire due to water sprayed from the upper side, and prevents dust and impurities falling into the sprinkler pipe from the upper side. It can also function as a protection, and in this case, it is also called a shielding device or'shielding plate' because it functions as a shield.

And, such a'collecting plate' or'shielding plate' is a bottom-up type applied when a sprinkler is attached in a vertical direction to a pipe according to the type of sprinkler installed, and a side wall type applied when a sprinkler is attached in a horizontal direction to a pipe. In this case, the present invention can be applied to fix the'collecting plate' or'shield plate' to the sprinkler. In addition, when a protection net for protecting the sprinkler from foreign matter is covered, a device for fixing the protection net to the sprinkler is also required, and the present invention may also be applied in this case.

Such a conventional heat collecting plate or shielding plate is disclosed in Registration Utility Model Publication No. 20-0472191 (2014.04.09. Announcement). However, in the prior art, since the part that is deformed to have elasticity is in the direction of the thickness of the plate, the elasticity is very high or it is difficult to control the elasticity, especially when placing the ladder in a high position, so excessive force must be applied. There is a risk of falling over, and it has a problem that it is difficult to work alone.
