Document Type and Number:
WIPO Patent Application WO/2020/166937
Kind Code:
A1
Abstract:
The present invention relates to an angle-type dry pendent sprinkler head which is installed on a wall surface of a building to extinguish a fire early by sprinkling firewater in the event of a fire, and allows a dry pendent having an improved structure to be installed without winding a heating wire on a portion where a wall forms an angle of 90°. To this end, the present invention comprises: a first dry pendent (10) which is connected to a branch pipe (93) and is provided with a first flow path opening/closing means (20) for closing a portion connected to the branch pipe and maintaining an empty space therein; a pull-out means (21) installed at a side of the first flow path opening/closing means (20) to be compressed; an elbow (30) coupled to an end of the first dry pendent (10); a power transfer means (40) which is installed in the elbow (30) so as to change the power direction by 90° and transmit the power of the pull-out means; a second dry pendent (60) which is coupled to an opposite end of the elbow (30) and is provided with a second flow path opening/closing means (50) operated by the power transferred through the power transfer means (40); first and second bushings (31) and (32) for coupling the first and second dry dependents (10) and (60) to the elbow (30) so as to maintain airtightness; a frame (61) which is coupled to the second dry pendent (60) via a screw and has an open outlet; an omnidirectional deflector (70) which is installed in the frame (61) so as to be pulled out and is provided with a flange (71) at one end thereof and a plurality of upward bending portions (74) at the other end thereof so as to form a spraying space (73) radially from a flat bottom surface (72); and a heat collector (80) which is installed at an outlet side of the frame (61) such that the omnidirectional deflector (70) can be accommodated in the frame (61), and which responds to fire.
